OBJECTIVES--To compare analgesic efficacy and pain caused by administration of lidocaine/prilocaine cream (EMLA(R)) versus xylocaine 1% local infiltration for punch biopsy and electrocoagulation of genital warts in men. DESIGN--Open randomised comparative parallel-group study. SETTING--Department of Dermatovenereology, University Hospital Rotterdam/Dijkzigt, the Netherlands. PATIENTS--63 males with warts on the genital mucosa and/or perianal area. METHODS--EMLA(R) cream (2.5-5 g) was applied during 13-45 minutes before surgery. Xylocaine 1% (0.1-4 ml) was infiltrated 0.5-4 minutes before surgery. Pain during administration and surgery was assessed by the patient on a verbal rating scale and on a visual analogue scale. RESULTS--EMLA(R) application was painless in all patients (n = 31) whereas xylocaine infiltration was slightly painful in 17/29 patients and moderately painful in 10/29 patients. EMLA(R) analgesia was satisfactory for 94% of biopsies and 62% of electrocoagulations. Xylocaine infiltration was satisfactory in all procedures. CONCLUSIONS--EMLA(R) application on the male genital mucosa is painless but it has a lower analgesic efficacy than xylocaine infiltration. However EMLA is a useful anaesthetic for taking biopsies in this area and may be used as premedication for local infiltration. PMID:1607191

More than 50% of children report apian during venepuncture or intravenous cannulation and using local anaesthetics before needle procedures can lead to different success rates. This study examined how many needle procedures were successful at the first attempt when children received either a warm lidocaine and tetracaine patch or an eutectic mixture of lidocaine and prilocaine (EMLA) cream. We conducted this multicentre randomised controlled trial at three tertiary-level children's hospitals in Italy in 2015. Children aged three to 10 years were enrolled in an emergency department, paediatric day hospital and paediatric ward and randomly allocated to receive a warm lidocaine and tetracaine patch or EMLA cream. The primary outcome was the success rate at the first attempt. The analysis included 172 children who received a warm lidocaine and tetracaine patch and 167 who received an EMLA cream. The needle procedure was successful at the first attempt in 158 children (92.4%) who received the warm patch and in 142 children (85.0%) who received the cream (p = 0.03). The pain scores were similar in both groups. This study showed that the first-time needle procedure success was 7.4% higher in children receiving a warm lidocaine and tetracaine patch than EMLA cream. ©2017 Foundation Acta Paediatrica.

Dental pain management is one of the most critical aspects of modern dentistry which might affect patient's quality of life. Several methods are suggested to provide a painless situation for patients. Desensitization of the oral site using topical anesthetics is one of those methods. The improvements of topical anesthetic agents are probably one of the most important advances in dental science in the past 100 years. Most of them are safe and can be applied on oral mucosa with minimal irritation and allergic reactions. At present, these agents are various with different potent and indications. Eutectic mixture of local anesthetics (EMLA) (lidocaine + prilocaine) is a commercial anesthetic agent which has got acceptance among dental clinicians. This article provides a brief review about the efficacy of EMLA as a topical anesthetic agent when used during dental procedures. PMID:27746520

Previous work indicates that sympathetic nerves participate in the vascular responses to direct cooling of the skin in humans. We evaluated this hypothesis further in a four-part series by measuring changes in cutaneous vascular conductance (CVC) from forearm skin locally cooled from 34 to 29 degrees C for 30 min. In part 1, bretylium tosylate reversed the initial vasoconstriction (-14 +/- 6.6% control CVC, first 5 min) to one of vasodilation (+19.7 +/- 7.7%) but did not affect the response at 30 min (-30.6 +/- 9% control, -38.9 +/- 6.9% bretylium; both P < 0.05, P > 0.05 between treatments). In part 2, yohimbine and propranolol (YP) also reversed the initial vasoconstriction (-14.3 +/- 4.2% control) to vasodilation (+26.3 +/- 12.1% YP), without a significant effect on the 30-min response (-26.7 +/- 6.1% YP, -43.2 +/- 6.5% control; both P < 0.05, P > 0.05 between sites). In part 3, the NPY Y1 receptor antagonist BIBP 3226 had no significant effect on either phase of vasoconstriction (P > 0.05 between sites both times). In part 4, sensory nerve blockade by anesthetic cream (Emla) also reversed the initial vasoconstriction (-20.1 +/- 6.4% control) to one of vasodilation (+213.4 +/- 87.0% Emla), whereas the final levels did not differ significantly (-37.7 +/- 10.1% control, -37.2 +/- 8.7% Emla; both P < 0.05, P > 0.05 between treatments). These results indicate that local cooling causes cold-sensitive afferents to activate sympathetic nerves to release norepinephrine, leading to a local cutaneous vasoconstriction that masks a nonneurogenic vasodilation. Later, a vasoconstriction develops with or without functional sensory or sympathetic nerves.

Sixty animals were divided into 4 groups: group 1, saline solution (control); group 2, poloxamer gel (thermosetting vehicle); group 3, lidocaine and prilocaine poloxamer thermosetting gel; group 4: EMLA, a lidocaine and prilocaine dermatological cream. Injections of 2% Evans blue were administrated intravenously into the lateral caudal vein. In order to analyze vascular permeability, the tested substances were injected intradermally. The rats were sacrificed 3, 6, and 9 hours after injection of the substances. The dorsal skin was dissected and removed. The vascular permeability was evaluated by the measurement of area of dye extravasation and the dye was subsequently extracted after immersion in formamide. Statistical analyses were made by ANOVA with Bonferroni's post hoc test and Pearson correlation. The 2 methods to analyze the exudative phase of the inflammatory process showed statistically significant difference among the groups and periods of evaluation (P < .05). Both methods had a significant correlation (P < .0001). Under the tested conditions, the anesthetic agents showed mild initial inflammatory response when implanted in subcutaneous connective tissue.

A simple approach for the synthesis of Lidocaine-Ibuprofen ionic liquid stabilized silver nanoparticles (IL-AgNPs) was reported in this work. The shape, size and surface morphology of the Lidocaine-Ibuprofen ionic liquid stabilized AgNPs were characterized by using spectroscopic and microscopic techniques such as Ultraviolet-visible spectroscopy (UV-Visible), X-ray diffraction (XRD) analysis, Selected area electron diffraction (SAED), Transmission electron microscopy (TEM). TEM analysis showed the formation of 20-30nm size of IL-AgNPs with very clear lattice fringes. SAED pattern confirmed the highly crystalline nature of fabricated IL stabilized AgNPs. EDS results confirmed the formation of nanosilver. The fabricated IL-AgNPs were studied for their local anesthetic effect in rats. The results of local anesthetic effect showed that the time for onset of action by IL-AgNPs is 10min, which is significantly higher than that for EMLA. Further, tactile test results confirmed the stronger and faster local anesthetic effect of IL-AgNPs when compared to that of EMLA. Copyright © 2017. Published by Elsevier B.V.

Amide local anaesthetics have previously been shown to reduce oedema and improve dermal perfusion following experimental burns. Previous studies have used invasive techniques for burn oedema quantification which do not allow continuous monitoring in the same animal. The present study used digital image colour analysis to investigate the effect of topical local anaesthetics on burn-induced extravasation of Evans blue albumin. A standardised full-thickness burn injury (1 x 1 cm) was induced in the abdominal skin of anaesthetised rats. The burn area was subsequently covered with 0.5 g of lidocaine-prilocaine cream 5% (25 mg of each in 1 g; EMLA, ASTRA, Sweden) or placebo cream during the first hour post-burn. One hour after the burn trauma, animals received Evans blue dye intravenously. Skin colour appearances were recorded by macrophotography before the burn and 5, 60. 65, 90, 120, 150, and 180 min post-burn. Colour slides were digitised and colour changes were analysed using the normalised red-green-blue (n-rgb) colour system. Results showed a significant inhibition of Evans blue extravasation between 60 and 180 min post-burn in EMLA-treated animals versus controls. Topical local anaesthetics are potent inhibitors of burn-induced plasma albumin extravasation, probably by direct action on vascular permeability and by inhibition of various steps of the pathophysiological response after burn injury.

ELA-max: A new topical lidocaine formulation.

Goldman, Ran D

2004-05-01

To evaluate the role of a new formulation of lidocaine (ELA-max) in local anesthesia in children and compare it with the eutectic mixture of local anesthetics (EMLA). Relevant literature was identified by a MEDLINE search (1966-November 2003) using the search terms ELA-max and EMLA. Bibliographies of selected articles were also examined to include all relevant investigations. The product manufacturer was contacted for inclusion of the most recent data available. Topical anesthesia in children is clinically challenging. ELA-max has been shown to be as effective as EMLA for venipuncture in children, but with faster onset. Adverse effects, such as transient blanching with redness and erythema, have been reported. Further investigation is needed to determine the effectiveness of ELA-max on other painful procedures in children, as well as its safety.

Introduction. Topical application of local anesthetics is currently considered to be the easiest, most effective, and convenient way for treatment of patients who may be undergoing superficial dermatosurgical procedures. Materials and Methods. This study compares the anesthetic potential of 2.5% lidocaine and 2.5% prilocaine topical cream with 7% lignocaine and 7% tetracaine combination cream for radio ablative dermatosurgery when applied, under occlusion, for 30 minutes. 40 subjects of achrocordons were enrolled in this split-side randomized trial. Result. The pain severity experienced by subjects in terms of visual analogue scale score was significantly lesser for lignocaine/tetracaine combination cream as compared to lidocaine/prilocaine combination. Conclusion. This small study proves the efficacy of lidocaine/tetracaine combination as a topical anesthetic cream when applied for a short time interval of 30 minutes. This will help a dermatosurgeon to perform various dermatological procedures in a better and efficient manner with a shorter waiting period for analgesia to set in. PMID:24600520

Recent advances in topical anesthesia

PubMed Central

2016-01-01

Topical anesthetics act on the peripheral nerves and reduce the sensation of pain at the site of application. In dentistry, they are used to control local pain caused by needling, placement of orthodontic bands, the vomiting reflex, oral mucositis, and rubber-dam clamp placement. Traditional topical anesthetics contain lidocaine or benzocaine as active ingredients and are used in the form of solutions, creams, gels, and sprays. Eutectic mixtures of local anesthesia cream, a mixture of various topical anesthetics, has been reported to be more potent than other anesthetics. Recently, new products with modified ingredients and application methods have been introduced into the market. These products may be used for mild pain during periodontal treatment, such as scaling. Dentists should be aware that topical anesthetics, although rare, might induce allergic reactions or side effects as a result of an overdose. Topical anesthetics are useful aids during dental treatment, as they reduce dental phobia, especially in children, by mitigating discomfort and pain. PMID:28879311

While there are many reasons people choose not to donate blood, pain sustained during the venipuncture portion of the blood donation process is likely one deterrent to volunteer donation. The purpose of this study was to survey the improvement in likelihood of donation if participants were given the option of a topical anesthetic cream prior to venipuncture. Over a three month period 316 adults (convenience sample) completed a one page survey consisting of twelve questions pertaining to blood donation. Participants were asked about their likelihood of donating blood in the near future (No Possibility, Possible, Likely, Certain). They were then informed of the possibility of using a topical anesthetic cream prior to donation. Subsequently, their likelihood of donating blood was reassessed. Fifty (16%) subjects reported an increased likelihood of donating blood if offered a topical anesthetic (p〈0.0001). Of these respondents reporting an increase in donation likelihood, eleven improved by 2 or more likelihood categories. Amongst the 169 participants who never donated blood, 34 (20%) reported an increased likelihood of donation after being told about the topical anesthetic cream, compared to 16 (10%) of the 147 subjects who had previously donated blood (p=0.02). The findings of this study suggest that providing a topical anesthetic had a positive effect on the study participants' likelihood of donating blood. This improvement was greater amongst those who have never donated blood. Hawaii Medical Journal Copyright 2011.

Comparison of skin anesthetic effect of liposomal lidocaine, nonliposomal lidocaine, and EMLA using 30-minute application time.

Liposomes are microscopic phospholipid vessels that have been utilized to extend the action of topical medications. Previous studies have demonstrated that liposomal vehicles can prolong the action of a variety of medications, including antifungals, anesthetics, interferon, and antineoplastic agents. The purpose of this study was to examine the degree and duration of anesthesia produced by lidocaine in a liposomal vehicle compared with lidocaine in a nonliposomal vehicle and compared with EMLA. The topical preparations in this study were allowed to contact the skin for a 30-minute period prior to evaluation of anesthetic effectiveness. Unoccluded and Tegaderm-occluded topical preparations were evaluated in two separate arms of the study. Thirteen healthy volunteers (three male, 10 female) were recruited for the nonocclusion arm of the study. Six healthy volunteers (two male, four female) were recruited for the occlusion arm of the study. Subjects with a history of allergy to lidocaine, a history of seizures, cardiac or respiratory difficulty, pregnant patients, and patients less than 18 years old were excluded. Written informed consent was obtained from all patients prior to testing. The volar forearms of the volunteers were swabbed with isopropyl alcohol and allowed to dry. A template was then utilized to mark 2 x 2-cm squares with a skin marker on both volar forearms. In total, nine squares corresponding to nine test areas were marked. The nine test preparations were applied to the test areas in a double-blinded fashion using a clean swab stick. The test preparations were then allowed to remain on the skin for 30 minutes in either occluded or nonoccluded from depending upon the arm of the study. Following the 30-minute application period, the test preparations were wiped off with clean gauze. Testing for anesthesia was performed by following a previously published method utilizing gentle pinpricks. A new pinprick apparatus was used for each patient. Pinprick testing was performed at 0, 15, 30, 60, and 90 minutes following the end of the 30-minute application period. Patients' responses to the pinprick were recorded in a binary fashion, as being either: 1) totally painless or 0) painfully sharp to any degree. Ten applications of the pinprick were applied randomly across each 2 x 2-cm test area. The number of painless applications of the pinprick out of a total of 10 applications of the pinprick was then recorded for each test area at every particular test time. In total, nine test preparations were evaluated. Analysis of the data was performed by a PhD statistical faculty consultant from the UCLA Mathematics Department. Liposomal lidocaine preparations evidenced longer durations of anesthesia than lidocaine preparations in nonliposomal vehicles. Five percent liposomal lidocaine preparations were statistically equivalent to EMLA in anesthetic effectiveness. Five percent liposomal lidocaine is an effective alternative topical agent for use in the attainment of temporary local anesthesia of the skin.

To characterize liposomal-lidocaine formulations for topical use on oral mucosa and to compare their in vitro permeation and in vivo anesthetic efficacy with commercially available lidocaine formulations. Large unilamellar liposomes (400 nm) containing lidocaine were prepared using phosphatidylcholine, cholesterol, and α-tocoferol (4:3:0.07, w:w:w) and were characterized in terms of membrane/water partition coefficient, encapsulation efficiency, size, polydispersity, zeta potential, and in vitro release. In vitro permeation across pig palatal mucosa and in vivo topical anesthetic efficacy on the palatal mucosa in healthy volunteers (double-blinded cross-over, placebo controlled study) were performed. The following formulations were tested: liposome-encapsulated 5% lidocaine (Liposome-Lido5); liposome-encapsulated 2.5% lidocaine (Liposome-Lido2.5); 5% lidocaine ointment (Xylocaina®), and eutectic mixture of lidocaine and prilocaine 2.5% (EMLA®). The Liposome-Lido5 and EMLA showed the best in vitro permeation parameters (flux and permeability coefficient) in comparison with Xylocaina and placebo groups, as well as the best in vivo topical anesthetic efficacy. We successfully developed and characterized a liposome encapsulated 5% lidocaine gel. It could be considered an option to other topical anesthetic agents for oral mucosa.

Since topical anesthetics alone seldom provide adequate analgesia for laser resurfacing procedures, injectable forms of anesthesia are often required. However, their application is uncomfortable for the patient. In this study, it is investigated whether microneedle application would enhance the efficacy of topical anesthetics. Forty-seven patients participated in the study. Topical anesthetic agent EMLA was applied to the whole face of the patients. Microneedle treatment was applied to one side of the face with a roller-type device. Whole-face carbon dioxide laser resurfacing therapy was carried out then. The pain that patients experienced was assessed by using visual analog scale (VAS) method. VAS scores of two sides of the face were compared by using Wilcoxon signed-rank test. The mean of VAS score of the microneedle treated side was 2.1 ± 1.1 while that of the untreated side was 5.9 ± 0.9 and this difference was statistically significant (Wilcoxon signed-rank test, the Z-value is - 5.9683 and the p-value is < 0.001). This study revealed that microneedle application, with a roller-type device, is a safe and easy procedure in providing sufficient anesthesia for facial laser resurfacing without the need for supplementary nerve blocks or injections.

Skin blood flow responses to the iontophoresis of acetylcholine and sodium nitroprusside in man: possible mechanisms.

Morris, S J; Shore, A C

1996-10-15

1. The mechanisms involved in the human skin blood flow responses to iontophoretic application of acetylcholine (ACH; delivered using an anodal charge) or sodium nitroprusside (SNP; administered with a cathodal charge) are unclear. The aims of this study were to investigate possible contributions of prostaglandin production to the increase in skin blood flow induced following the iontophoresis of ACh and to investigate possible contributions from local sensory nerves to the perfusion responses induced by ACh, SNP and their vehicles. 2. The contribution of prostaglandins to the ACh response was determined in a randomized double-blind study of eight healthy subjects, who were studied on two occasions. Basal responses to ACh were measured before the oral administration of 600 mg soluble aspirin in diluted orange juice (1 occasion or orange juice (1 occasion) and again 30 min after the drink. The contribution of local sensory nerve activation to the responses to ACh and ACh vehicle (8 subjects) and to SNP and SNP vehicle (7 subjects) was assessed. EMLA (5%) (a eutectic mixture of lignocaine and prilocaine) and placebo cream were applied to two separate areas on the forearm in a double-blind randomized manner 2 h before drug responses were measured. In all studies the skin microcirculation responses to iontophoretically applied drug vehicle (1 site) and drug (2 sites) were recorded by laser Doppler perfusion imaging. 3. The increase in forearm skin perfusion (P < 0.001) in response to the iontophoresis of ACh minus the response to ACh vehicle was not significantly different following placebo or aspirin administration. The increase in forearm skin red blood cell flux (P < 0.001) in response to the iontophoresis of ACh minus the response to ACh vehicle was not significantly different at the placebo-compared with the EMLA-treated site. THe small increase in perfusion (P < 0.001) in response to the iontophoresis of ACh vehicle was significantly inhibited at the EMLA-compared with the placebo-treated site (P < 0.05). The marked increase in perfusion (P < 0.001) in response to the iontophoresis of SNP vehicle was significantly inhibited at the EMLA-compared with the placebo-treated site (P < 0.01). 4. These data suggest that in healthy volunteers: (1) mechanisms other than prostaglandin production and local sensory nerve activation may be involved in the increase in skin perfusion observed following the iontophoretic application of ACh; and (2) stimulation of local sensory nerves may be responsible for the increase in tissue perfusion observed following the iontophoretic application of either ACh vehicle or SNP vehicle.

Topical anesthetics have evolved from a simple solution of cocaine to creams, ointments, gels, liposomal preparations, and to the latest sophisticated patches and peels. Topical anesthetics are essential for performing diagnostic, therapeutic, and cosmetic dermatology procedures. These anesthetics noninvasively deliver anesthesia in locally required areas. In this review, we present an overview on the mechanism of precutaneous absorption of skin and address the composition, duration of onset of anesthetic effect, uses, and side effects that are applicable for the products. Also discussed are the novel advances of using heat to enhance penetration of the anesthetic as seen in Synera™ patch and delivery of anesthesia using a peel method as seen in the yet to be US Food and Drug Administration-approved S-Caine peel.

Injection of dermal fillers for soft tissue augmentation is a minimally invasive cosmetic procedure with growing popularity. However, patients often express concern about pain with such procedures. A topical anesthetic cream formulated with lidocaine/tetracaine 7%7% was approved by the United States Food and Drug Administration in 2006 and recently reintroduced to the market for use during superficial dermatological procedures. A Phase 3 study was conducted to assess the efficacy and safety of lidocaine/tetracaine 7%7% cream versus placebo cream when used to induce local dermal anesthesia during injections with hyaluronic acid. Mean visual analog scale scores significantly favored lidocaine/tetracaine 7%7% cream. A significant percent of subjects also indicated that lidocaine/tetracaine 7%7% cream provided adequate pain relief and that they would use lidocaine/tetracaine 7%7% cream again. Investigators also rated lidocaine/tetracaine 7%7% cream significantly better than placebo cream for providing adequate pain relief and on the assessment of pain scale. Lidocaine/tetracaine 7%7% cream was safe and well tolerated with most subjects reporting no erythema, edema, or blanching. No related adverse events were reported with lidocaine/tetracaine 7%7% cream; one related adverse event of erythema was reported with placebo cream. The results of this study indicate that lidocaine/tetracaine 7%7% cream is efficacious and safe at providing pain relief for soft tissue augmentation with hyaluronic acid.

Lidocaine/tetracaine 7%7% cream was safe and well tolerated with most subjects reporting no erythema, edema, or blanching. No related adverse events were reported with lidocaine/tetracaine 7%7% cream; one related adverse event of erythema was reported with placebo cream. The results of this study indicate that lidocaine/tetracaine 7%7% cream is efficacious and safe at providing pain relief for soft tissue augmentation with hyaluronic acid. PMID:25371769

Aim: The purpose of the present study was to determine the potential of Jatropha curcas latex in the cream formulation on CD68 immune expression (macrophages) during inflammatory phase wound healing process in mice skin. Materials and Methods: Amount of 12 two-months-old male mice were used between 30 and 40 g. To surgical procedures, wound skin incision was performed 2.0 cm in length until subcutaneous on the paravertebral of each animal. The treatment was carried under locally anesthetized with procaine cream. The mice were allotted into four groups of each, entire surface of each group wound covered by base cream control, sulfadiazine 0.1% cream, J. curcas latex cream 10% and, 15%, respectively. All experiments were performed twice a day for 3 days. The wound healing was assayed in stained histological sections in immunohistochemical of the wounds. CD68 expression was investigated under a microscope. Results: The results showed that the cream from the 10% and 15% latex of J. curcas revealed moderate immune reaction to CD68 on wound healing. Conclusion: We concluded that the latex cream of J. curcas possesses anti-inflammatory activity in wound healing process of mice skin. PMID:29657387

Facial burns are quite common among children. Many different wound-covers can be used for dressing burn wounds, which is usually painful for the patients. These covers can also be combined with local anesthetic creams. Lidocaine-prilocaine cream 5% (LPC) is commonly used as a topical anesthetic by physicians performing plastic surgery. In the present study, we investigated the effects of topical LPC on pain cessation in pediatric patients with face burn and compared results with a control group in which LPC was not used in the wound dressing. Thirty pediatric patients (average age 11.3, range 8-15) among those who admitted to our emergency service and plastic surgery outpatient clinic between 2003 and 2006 were included in this study. The patient's burned areas ranged between 1 and 5% percent of their total body surface. The need for analgesic medicine was recorded in the first, second and third 8-hour periods postburn in both groups, and pain level was evaluated at these time points using a verbal rating scale. There was a significant difference between the two groups with respect to values of the first and second 8-hour periods, while in the third 8-hour period, no significant difference was observed. We conclude that topical local anesthetics administered for 16 hours postburn significantly reduce the duration of pain after injury, which suggests a potential use in clinical practice in the treatment of children with face burn. While LPC was found to have an ameliorating effect in the first 16 hours, we recommend oral analgesic co-therapy support since it loses its efficacy in the last 8-hour period.

The aim of this work was to develop anesthetic bioadhesive films containing benzocaine and study their in vitro skin permeation and in vivo performance, in comparison with commercial formulations. Films containing 3% and 5% w/w of benzocaine were prepared and characterized by weight, drug content, thickness and morphology. In vitro permeation assays were performed in vertical diffusion cells using full-thickness pig ear skin as barrier. Intensity and duration of analgesia were evaluated in rats by tail-flick test, and skin histological analysis was carried out. Tail-flick test showed that the duration of benzocaine-induced analgesia was significantly prolonged with the films compared to commercial creams, in agreement with the higher in vitro permeation. Histological analysis of the rat tail skin did not reveal morphological tissue changes nor cell infiltration signs after application of the commercial creams or films. Results from our study indicate that the films developed in this work can be considered as innovative dermal/transdermal therapeutic systems for benzocaine local delivery.

We compare pain and anxiety associated with peripheral intravenous (IV) cannula insertion after pretreatment with no local anesthesia, 4% lidocaine cream, or subcutaneously injected, buffered 1% lidocaine. In a randomized, crossover design, 3 peripheral IVs were inserted in each of 70 medical students or nurses. In random order, insertion sites were pretreated with nothing, lidocaine cream, or injected, buffered lidocaine. After each IV insertion, subjects recorded pain, anxiety, and preference (as patient and provider) for each technique on a 10-point numeric rating scale. Higher scores indicated greater pain, anxiety, and preference. Median pain scores (interquartile range [IQR]) were 7 (4 to 8) without local anesthesia, 3 (2 to 5) with lidocaine cream, and 1 (1 to 2) with injected, buffered lidocaine. Median anxiety scores (IQR) were 4 (2 to 7) without local anesthesia, 2 (1 to 4) with lidocaine cream, and 2 (1 to 3) with injected, buffered lidocaine. There was no detectable difference in anxiety scores between lidocaine cream and injected, buffered lidocaine. Most IV placement attempts were successful, regardless of technique. Seventy percent of subjects indicated they would "always" request buffered lidocaine for peripheral IV insertion. In adult health care providers, pain and anxiety associated with peripheral IV insertion is significantly reduced by using topical lidocaine cream or injected, buffered lidocaine. Injected, buffered lidocaine reduces IV insertion pain more than lidocaine cream, without affecting success. Adults desire the use of local anesthetic techniques for IV insertion for themselves and for their patients.

Hospitalised newborn neonates frequently undergo painful invasive procedures that involve penetration of the skin and other tissues by a needle. One intervention that can be used prior to a needle insertion procedure is application of a topical local anaesthetic. To evaluate the efficacy and safety of topical anaesthetics such as amethocaine and EMLA in newborn term or preterm infants requiring an invasive procedure involving puncture of skin and other tissues with a needle. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase and CINAHL up to 15 May 2016; previous reviews including cross-references, abstracts, and conference proceedings. We contacted expert informants. We contacted authors directly to obtain additional data. We imposed no language restrictions. Randomised, quasi-randomised controlled trials, and cluster and cross-over randomised trials that compared the topical anaesthetics amethocaine and eutectic mixture of local anaesthetics (EMLA) in terms of anaesthetic efficacy and safety in newborn term or preterm infants requiring an invasive procedure involving puncture of skin and other tissues with a needle DATA COLLECTION AND ANALYSIS: From the reports of the clinical trials we extracted data regarding clinical outcomes including pain, number of infants with methaemoglobin level 5% and above, number of needle prick attempts prior to successful needle-related procedure, crying, time taken to complete the procedure, episodes of apnoea, episodes of bradycardia, episodes of oxygen desaturation, neurodevelopmental disability and other adverse events. Eight small randomised controlled trials met the inclusion criteria (n = 506). These studies compared either EMLA and placebo or amethocaine and placebo. No studies compared EMLA and amethocaine. We were unable to meta-analyse the outcome of pain due to differing outcome measures and methods of reporting. For EMLA, two individual studies reported a statistically significant reduction in pain compared to placebo during lumbar puncture and venepuncture. Three studies found no statistical difference between the groups during heel lancing. For amethocaine, three studies reported a statistically significant reduction in pain compared to placebo during venepuncture and one study reported a statistically significant reduction in pain compared to placebo during cannulation. One study reported no statistical difference between the two groups during intramuscular injection.One study reported no statistical difference between EMLA and the placebo group for successful venepuncture at first attempt. One study similarly reported no statistically significant difference between Amethocaine and the placebo group for successful cannulation at first attempt.Risk for local redness, swelling or blanching was significantly higher with EMLA (typical risk ratio (RR) 1.65, 95% confidence interval (CI) 1.24 to 2.19; typical risk difference (RD) 0.17, 95% CI 0.09 to 0.26; n = 272; number needed to treat for an additional harmful outcome (NNTH) 6, 95% CI 4 to 11; I 2 = 92% indicating considerable heterogeneity) although not for amethocaine (typical RR 2.11, 95% CI 0.72 to 6.16; typical RD 0.05, 95% CI -0.02 to 0.11, n = 221). These local skin reactions for EMLA and amethocaine were reported as short-lasting. Two studies reported no methaemoglobinaemia with single application of EMLA. The quality of the evidence on outcomes assessed according to GRADE was low to moderate. Overall, all the trials were small, and the effects of uncertain clinical significance. The evidence regarding the effectiveness or safety of the interventions studied is inadequate to support clinical recommendations. There has been no evaluation regarding any long-term effects of topical anaesthetics in newborn infants.High quality studies evaluating the efficacy and safety of topical anaesthetics such as amethocaine and EMLA for needle-related pain in newborn term or preterm infants are required. These studies should aim to determine efficacy of these topical anaesthetics and on homogenous groups of infants for gestational age. While there was no methaemoglobinaemia in the studies that reported methaemoglobin, the efficacy and safety of EMLA, especially in very preterm infants, and for repeated application, need to be further evaluated in future studies.

We observed that olfactory stimulation with scent of grapefruit oil elevated the activities of sympathetic nerves, and increased the plasma glycerol concentration and blood pressure. In contrast, olfactory stimulation with scent of lavender oil had opposite effects in rats. These suggest that changes in autonomic activities cause physiological functions via histaminergic H1 and H3 receptor. Moreover, it has been reported that somatic sensory stimulation affected autonomic neurotransmission. To examine effects of skin application of urea-containing cream on cutaneous arterial sympathetic nerve activity (CASNA), blood flow, and transepidermal water loss (TEWL). The activity of CASNA was determined by electrophysiological method, and cutaneous blood flow was determined using laser flowmeter in urethane-anesthetized rats, TEWL was measured using VapoMeter in the back skin of HWY hairless rats. CASNA was markedly and significantly inhibited by skin application of 10% urea-containing cream, whereas cutaneous blood flow was significantly elevated via histaminergic H3-receptor. In conscious hairless rats, TEWL was significantly decreased 24 h after application of 10% urea-containing cream to the back skin. These findings suggest that skin application of 10% urea-containing cream increases the cutaneous blood flow and water retaining ability, and that histaminergic H3-receptors may mediate these effects. © 2010 John Wiley & Sons A/S.

The aim of this study is to observe the synergistically enhanced percutaneous penetration and skin analgesia of tetracaine gel containing menthol and ethanol through experimental and clinical studies. Four anesthetic gels containing 4% tetracaine in carbomer vehicle named T-gel (containing no menthol or ethanol), 5%M/T-gel (containing 5% menthol), 70%E/T-gel (containing 70% ethanol, an optimal concentration for antiseptic), and 5%M+70%E/T-gel (containing both 5% menthol and 70% ethanol), respectively, were fabricated. The in vitro mouse skin permeation was investigated using a Franz diffusion cell. The mouse skin morphology was examined by a scanning electron microscope. The in vivo skin analgesic effect in mice was evaluated using the von Frey tests. To determine the efficacy of tetracaine gels for managing the pain in human volunteers, a paralleled, double-blinded, placebo-controlled, randomized controlled trial design combined with verbal pain scores (VPS) was performed. The combination of menthol and ethanol (5%M+70%E/T-gel) conferred significantly higher tetracaine diffusion across full-thickness mouse skin than 5%M/T-gel, 70%E/T-gel, and T-gel. The ultra structure changes of mouse skin stratum corneum treated with 5%M+70%E/T-gel were more marked compared with those of any other tetracaine gel. von Frey tests in mice showed a synergistically enhanced effect of menthol and ethanol on the analgesia of tetracaine gel. The mean VPS were significantly lower for volunteers treated with 5%M+70%E/T-gel than those receiving other gels or the EMLA cream. 5%M+70%E/T-gel possessed the shortest anesthesia onset time, the longest anesthesia duration and the strongest anesthesia efficacy. Seventy percent ethanol in 5%M+70%E/T-gel not only improved the analgesic efficacy of the tetracaine gel through synergistically enhanced percutaneous permeation with menthol but also served as an antiseptic agent keeping drug application site from infection. 5%M+70%E/T-gel is a potential topical anesthesia preparation for clinical use.

The aim of this study is to explore the effect of topical application of Aloe vera on skin wound healing. Thirty-six male Sprague-Dawley rats weighing 150-200 grams were divided into four groups. All groups were anesthetized, shaved, and exposed to round full-thickness punch biopsy on the back: group I (control); group II (treated with 1% Aloe vera cream); group III (treated with 2% Aloe vera cream); and group IV (treated with madecassol®). The treatments were given once a day. Macroscopic and microscopic examination were observed at 5, 10, and 15 days after skin biopsy. Skin specimens were prepared for histopathological study using H&E stain and IHC stain against CD4 + and CD8 + lymphocytes. All the data were analyzed using SPSS16. The result showed that topical application of 1% and 2% Aloe vera cream significantly reduced the percentage of the wound, leucocytes infiltration, angiogenesis, and expression of CD8 + lymphocytes and increased the epidermal thickness and the expression of CD4 + lymphocytes ( p ≤ 0,05). There was no significant difference in the number of fibroblasts in all groups. Topical application of 1% and 2% Aloe vera cream has wound healing potential via their ability to increase the ratio of CD4 + /CD8 + lymphocytes in the wound area.

Heightened motor and sensory (mirror-touch) referral induced by nerve block or topical anesthetic.

Mirror neurons allow us to covertly simulate the sensation and movement of others. If mirror neurons are sensory and motor neurons, why do we not actually feel this simulation- like "mirror-touch synesthetes"? Might afferent sensation normally inhibit mirror representations from reaching consciousness? We and others have reported heightened sensory referral to phantom limbs and temporarily anesthetized arms. These patients, however, had experienced illness or injury of the deafferented limb. In the current study we observe heightened sensory and motor referral to the face after unilateral nerve block for routine dental procedures. We also obtain double-blind, quantitative evidence of heightened sensory referral in healthy participants completing a mirror-touch confusion task after topical anesthetic cream is applied. We suggest that sensory and motor feedback exist in dynamic equilibrium with mirror representations; as feedback is reduced, the brain draws more upon visual information to determine- perhaps in a Bayesian manner- what to feel.

Pain management policies and practices in pediatric emergency care: a nationwide survey of Italian hospitals

PubMed Central

2013-01-01

Background Pain experienced by children in emergency departments (EDs) is often poorly assessed and treated. Although local protocols and strategies are important to ensure appropriate staff behaviours, few studies have focussed on pain management policies at hospital or department level. This study aimed at describing the policies and reported practices of pain assessment and treatment in a national sample of Italian pediatric EDs, and identifying the assocoated structural and organisational factors. Methods A structured questionnaire was mailed to all the 14 Italian pediatric and maternal and child hospitals and to 5 general hospitals with separate pediatric emergency room. There were no refusals. Information collected included the frequency and mode of pain assessment, presence of written pain management protocols, use of local anaesthetic (EMLA cream) before venipuncture, and role of parents. General data on the hospital and ED were also recorded. Multiple Correspondence Analysis was used to explore the multivariable associations between the characteristics of hospitals and EDs and their pain management policies and practices. Results Routine pain assessment both at triage and in the emergency room was carried out only by 26% of surveyed EDs. About one third did not use algometric scales, and almost half (47.4%) did not have local protocols for pain treatment. Only 3 routinely reassessed pain after treatment, and only 2 used EMLA. All EDs allowed parents’ presence and most (17, 89.9%) allowed them to stay when painful procedures were carried out. Eleven hospitals (57.9%) allowed parents to hold their child during blood sampling. Pediatric and maternal and child hospitals, those located in the North of Italy, equipped with medico-surgical-traumatological ED and short stay observation, and providing full assessment triage over 24 hours were more likely to report appropriate policies for pain management both at triage and in ER. A nurses to admissions ratio ≥ median was associated with better pain management at triage. Conclusions Despite availability of national and international guidelines, pediatric pain management is still sub-optimal in Italian emergency departments. Multifaceted strategies including development of local policies, staff educational programs, and parental involvement in pain assessment should be carried out and periodically reinforced.

The aim of this study was to assess the efficacy in pain reduction of topical 2 % lidocaine compared to a placebo cream in children with oral mucosal lesions due to trauma or aphthous ulcers or in the prevention of clamp placement pain. The design was a double-blind, randomized, placebo-controlled, four-center trial on 64 patients. Pain intensity and relief were measured using a 100-mm visual analog scale (VAS). One-tailed Student's t test and ANOVA were used for statistical analyses. Independent of the pain origin, application of 2 % lidocaine cream led to a mean reduction in VAS pain intensity of 19.7 mm ± 18.3, which was significantly greater than that obtained with the placebo cream (p = .025). Analyses showed a statistically significant efficacy of the 2 % lidocaine cream (p < .0001). Its efficacy was not associated to any local or systemic adverse drug reaction, as reported by the patients. As the most important population represented in our patients was children whom a rubber dam clamp was placed, we also specifically analysed this population, and we were able to demonstrate a significantly greater efficacy of the 2 % lidocaine cream on the pain caused by the rubber dam clamp placement in comparison to the placebo cream (p < .005). A significant reduction in pain intensity occurred after application of 2 % lidocaine cream, and the effect was significantly greater than that obtained with the placebo cream. Considering the study's limitations, this product appears safe for use in children. For painful benign lesions of the oral mucosa (trauma or aphthous ulcers) or for preventing painful iatrogenic procedures such as rubber dam clamp placement, it is essential to treat or prevent pain onset, especially in the pediatric population for whom a painful experience could end in refusal of dental care. Application of a topical anesthetic in this specific situation is of particular interest, as is defining its efficacy and safety.

Needle-related procedures (venipuncture, intravenous cannulation) are the most common source of pain and distress for children. Reducing needle related pain and anxiety could be important in order to prevent further distress, especially for children needing multiple hospital admissions. The aim of the present open randomized controlled trial was to investigate the efficacy of adding an active distraction strategy (videogame) to EMLA premedication in needle-related pain in children. One-hundred and nine children (4 -10 years of age) were prospectively recruited to enter in the study. Ninety-seven were randomized in two groups: CC group (conventional care: EMLA only) as control group and AD group (active distraction: EMLA plus videogame) as intervention group. Outcome measures were: self-reported pain by mean of FPS-R scale (main study outcome), observer-reported pain by FLACC scale, number of attempts for successful procedure. In both groups FPS-R median rate was 0 (interquartile range: 0-2), with significant pain (FPS-R > 4) reported by 9% of subjects. FLACC median rate was 1 in both groups (interquartile range 0-3 in CC group; 0-2 in AD group). The percentage of children with major pain (FLACC > 4) was 18% in CC group and 9% in AD group (p = 0.2). The median of necessary attempts to succeed in the procedures was 1 (interquartile range 1-2) in both groups.. Active distraction doesn't improve EMLA analgesia for iv cannulation and venipuncture. Even though, it resulted in an easily applicable strategy appreciated by children. This technique could be usefully investigated in other painful procedures.

Ehrlichiosis and anaplasmosis are important emerging tickborne zoonoses that affect both humans and animals. Knowledge of the geographic distribution and prevalence of Ehrlichia spp. and Anaplasma phagocytophilum in Wisconsin is important information as a baseline for future comparisons. Reported human cases between 2009 and 2015 were identified using the Wisconsin Electronic Disease Surveillance System (WEDSS) and mapped by county of residence. Vector surveillance was established using ticks collected from animals by partners, including veterinary medical clinics, domestic animal shelters, and wildlife rehabilitation centers from 40 Wisconsin counties. A total of 1835 Ixodes scapularis tick specimens (larvae, nymphs, and adults) were collected from 18 different domestic and wildlife species from July 2011 to November 2015. An additional 1136 nymphs were collected by drag sampling at 23 locations in 19 counties in 2015. A real-time PCR assay that detects and distinguishes several Ehrlichia species, including a pathogenic Ehrlichia muris-like agent (EMLA), and A. phagocytophilum was performed on adult and nymphal ticks. A total of 757 I. scapularis ticks (predominately adults) were tested from animal collections, with 67 (8.9%) individuals positive for A. phagocytophilum and 22 (2.9%) positive for EMLA DNA. Of the 1150 questing nymphs, 62 (5.4%) were positive for A. phagocytophilum and 10 (0.9%) were positive for EMLA DNA. Specimens of I. scapularis that were positive for A. phagocytophilum were found in 27 of the 33 counties surveyed. Specimens that were positive for EMLA were less common and were found in nine counties. This study provides the first statewide survey of I. scapularis ticks for these pathogens and indicates that the risk of human exposure is widely distributed.

Effects on skin blood flow by provocation during local analgesia.

Although topical analgesia cream has been used for several years, little is known about its effects on the microcirculation. Previous studies have shown a vasoconstrictive effect after short application times and a vasodilatation after longer application. It has also been shown that vasomotion does not occur in the analgesized skin. The present study was undertaken to investigate the alterations in skin blood perfusion following local cooling, local heating and pin-pricking after the establishment of analgesia. In 11 healthy volunteers, skin analgesia was attained by use of a eutectic mixture of lidocaine and prilocaine (EMLA, Astra Pain Control AB, Sweden) applied to the skin three hours prior to provocation. The changes in skin blood perfusion, after applying three different provocation methods, were studied using the laser Doppler technique. Local cooling and heating to temperatures of +10 and +45 degrees C, respectively, were applied for 9 s by use of a copper probe (O12 mm). In the pin-prick provocation method, a combined effect of deflection and penetration of the skin to in total 3 mm was attained. Identical provocation methods were applied to placebo treated and untreated skin areas. After heat provocation, significant differences in the perfusion response between the treatments were seen (P < 0.0001). Skin areas treated with analgesia cream responded with a slow increase in perfusion that persisted beyond the four minute measurement period. Placebo and untreated areas decreased their perfusion over time. After cooling a significant reduction in skin perfusion was seen, irrespective of the treatment. Similarly, after pin-pricking a perfusion increase was seen for all treatments. The findings indicate that topical analgesia influences the myogenic control of the blood flow in those vascular plexa measured by laser Doppler following heat provocation. No differences could be seen in the response to pin-pricking and cooling for the different treatments. Copyright 2000 Academic Press.

Nitrous oxide availability.

Murray, M J; Murray, W J

1980-04-01

Nitrous oxide (N2O) is marketed as an inhalation anesthetic and as a food ingredient (e.g., whipping cream propellant). In the human, inhalation has been associated with "highs," peripheral nerve damage, mitotic poisoning of bone marrow, psychosis, and mental impairment. Exposure to hypoxemic mixtures has resulted in death. The commercial N2O sources specifically studied were aerosol whipping cream containers (three brands) and 6.5-cm cylinders, or chargers (two brands). The gas content and N2O concentrations of these devices were measured. The aerosol cans, when not shaken, will dispense at least 3 liters of 87 to 90% N2O. Charger misuse may occur when they are substituted for identically designed carbon dioxide (CO2) chargers of a seltzer bottle; 4.3 to 5.0 liters of 93 to 98% N2O is expelled at a controllable rate. The toxicity of these inexpensive N2O products, their high potential for misuse, and the absence of labeling (chargers) argue that their distribution be discontinued.

Topical capsaicin 8% was developed for the treatment of peripheral neuropathic pain. The pain reduction is associated with a reversible reduction of epidermal nerve fiber density (ENFD). During its application, topical capsaicin 8% provokes distinct pain. In a randomized, double-blind study analyzed with a block factorial analysis of variance, we tested whether cooling the skin would result in reliable prevention of the application pain without inhibiting reduction of ENFD. A capsaicin 8% patch was cut into 4 quarters and 2 each were applied for 1 hour on the anterior thighs of 12 healthy volunteers. A randomization scheme provided for 1 of the application sites of each thigh to be pretreated with EMLA and the other with placebo, whereas both application sites of 1 thigh, also randomly selected, were cooled by cool packs, resulting in a site temperature of 20°C during the entire treatment period. The maximum pain level given for the cooled sites (visual analogue scale [VAS] 1.3 ± 1.4) proved to be significantly lower than for the non-cooled sites (VAS 7.5 ± 1.9) (P < .0001). In contrast, there was no significant difference in application pain between the sites pretreated with EMLA or with placebo (VAS 4.1 ± 3.6 vs 4.8 ± 3.5, P = .1084). At all application sites, ENFD was significantly reduced by 8.0 ± 2.8 (ENF/mm ± SD, P < .0001), that is, 70%, with no significant differences between the sites with the different experimental conditions. In conclusion, cooling the skin to 20°C reliably prevents the pain from capsaicin 8% patch application, whereas EMLA does not. ENFD reduction is not inhibited by cooling.

Topical anaesthetic cream (TAC) is commonly used as a pre-treatment of ablative fractional resurfacing (AFR) laser. Most of anaesthetic cream contains distilled water as major component. Therefore, pre-operative TAC may interfere the photothermal reaction in the skin treated with fractional carbon-dioxide (FCO 2 ) laser and fractional erbium-doped yttrium aluminium garnet (FEr:YAG) laser. The objective of the study was to compare the ablative width (AW) and coagulative depth (CD) of AFR laser with and without pre-treatment with TAC. Four Thai females who underwent abdominoplasty were included in the study. The excised skin of each subject was divided into four areas. TAC (eutectic mixture of local anaesthesia; EMLA) with 1-h occlusion was applied only on the first and second areas. The first and third areas were treated with FCO 2 at 15 mj and 5% density. The second and fourth areas were treated with FEr:YAG at 28 J/cm 2 and 5% density. Six biopsied specimens were obtained from each area. A total of 96 specimens (24 specimens from each area) were collected from four patients and examined randomly by two dermatopathologists. The ablative width and coagulative depth from each specimen were determined. In FCO 2 -treated specimens, the mean AW of the specimens that were pre-treated with TAC and control was 174.86 ± 24.57 and 188.52 ± 41.32 μm. The mean CD of the specimens that were pre-treated with TAC and control was 594.96 ± 111.72 and 520.03 ± 147.40 μm. There were no significant differences in AW and CD between both groups (p = 0.53 and p = 0.15). In FEr:YAG-treated specimens, the mean AW of the specimens that were pre-treated with TAC and control was 381.11 ± 48.02 and 423.65 ± 60.16 μm. The mean CD of the specimens that were pre-treated with TAC and control was 86.03 ± 29.44 and 71.59 ± 18.99 μm. There were no significant differences in AW and CD between both groups (p = 0.16 and p = 0.24). The pre-treatment with TAC provided no statistically difference from the control group on AW and CD of both FCO 2 and FEr:YAG laser irradiation. However, there was a tendency to have narrower AW and deeper CD of the areas that were pre-treated with TAC when comparing to that of the control.

Whether men with lifelong premature ejaculation (PE) prefer on-demand drug treatment to delay ejaculation time to daily drug treatment, has never been studied as a separate study question. To study how men with lifelong PE feel about the use of serotonergic antidepressants, and which option they would prefer for themselves: either a daily drug, a drug to be used on demand, or a topical anesthetic cream to be applied on demand. Treatment preference was determined by questionnaire. An observational questionnaire survey in a clinical sample. Preferences of different treatment strategies were queried before and after standard efficacy and safety information. A consecutive group of 88 men with lifelong PE who decided for themselves to be seen for rapid ejaculation was studied. The age was 37 +/- 11 years (mean +/- SD), range 18-64 years. None of these men was ever treated for PE and 21% used medication that did not affect sexual performance. Of them, 71 (81%) preferred a drug for daily use, 14 (16%) a drug on demand, while three men preferred topical anesthetic cream. Those men who initially preferred daily treatment did not change their view after standard information about efficacy and side effects, while 9 of 17 men who initially preferred on-demand drug treatment had switched their preferences to daily oral drug usage. Around 60% of men did not care about the nature of the drug, i.e., an antidepressant. The most frequently reported argument to prefer daily drug treatment was that this strategy would have the least effects toward the spontaneity of having sex. As opposed to agents that must be taken 4-6 hours prior to coitus and with the methods used here, this group of Dutch men with lifelong PE favor uninterrupted daily drug treatment to delay ejaculation mainly because daily treatment guarantees no interference with the spontaneity of having sex.

Evidence that the human cutaneous venoarteriolar response is not mediated by adrenergic mechanisms

The venoarteriolar response causes vasoconstriction to skin and muscle via local mechanisms secondary to venous congestion. The purpose of this project was to investigate whether this response occurs through alpha-adrenergic mechanisms. In supine individuals, forearm skin blood flow was monitored via laser-Doppler flowmetry over sites following local administration of terazosin (alpha(1)-antagonist), yohimbine (alpha(2)-antagonist), phentolamine (non-selective alpha-antagonist) and bretylium tosylate (inhibits neurotransmission of adrenergic nerves) via intradermal microdialysis or intradermal injection. In addition, skin blood flow was monitored over an area of forearm skin that was locally anaesthetized via application of EMLA (2.5 % lidocaine (lignocaine) and 2.5 % prilocaine) cream. Skin blood flow was also monitored over adjacent sites that received the vehicle for the specified drug. Each trial was performed on a minimum of seven subjects and on separate days. The venoarteriolar response was engaged by lowering the subject's arm from heart level such that the sites of skin blood flow measurement were 34 +/- 1 cm below the heart. The arm remained in this position for 2 min. Selective and non-selective alpha-adrenoceptor antagonism and presynaptic inhibition of adrenergic neurotransmission did not abolish the venoarteriolar response. However, local anaesthesia blocked the venoarteriolar response without altering alpha-adrenergic mediated vasoconstriction. These data suggest that the venoarteriolar response does not occur through adrenergic mechanisms as previously reported. Rather, the venoarteriolar response may due to myogenic mechanisms associated with changes in vascular pressure or is mediated by a non-adrenergic, but neurally mediated, local mechanism.

This pilot study was designed to assess the impact of topical lidocaine and prilocaine cream on the pain response of very low birth weight infants undergoing percutaneous central venous line insertion. Infants were randomly assigned to receive 1 to 1.25 gm of the topical anesthetic or to receive zinc oxide placebo 1 hour before line insertion. Investigators blinded to treatment group assignment obtained serial measurements of heart rate, respiratory rate, systolic blood pressure, and oxygen saturation by pulse oximetry. Toxicity from lidocaine was assessed by clinical parameters, and toxic effects from prilocaine were assessed by methemoglobin levels (normal range 0% to 4%). Hearts rates increased significantly during line insertion in controls (n = 6) but not in treated patients (n = 7). Respiratory rates and blood pressure values increased significantly during line insertion in both groups. Oxygen saturation did not change significantly in either group. The percent of increase in heart and respiratory rates from baseline was attenuated in the treated patients compared with controls. Methemoglobin levels were 0.3% to 2.0% for the treated group and 0.3% to 0.7% for controls. The topical lidocaine and prilocaine cream application attenuated the lability of vital signs during line insertion in very low birth weight infants, with no evidence of toxicity.

Tail biopsy is a common procedure that is performed to obtain genetic material for determining genotype of transgenic mice. The use of anesthetics or analgesics is recommended, although identifying safe and effective drugs for this purpose has been challenging. We evaluated the effects of topical 2.5% lidocaine–2.5% prilocaine cream applied to the distal tail tip at 5 or 60 min before biopsy, immersion of the tail tip for 10 seconds in ice-cold 70% ethanol just prior to biopsy, and immersion of the tail tip in 0.5% bupivacaine for 30 s after biopsy. Mice were 7, 11, or 15 d old at the time of tail biopsy. Acute behavioral responses, plasma corticosterone, and blood glucose were measured after biopsy, and body weight and performance in elevated plus maze and open-field tests after weaning. Ice-cold ethanol prior to biopsy prevented acute behavioral responses to biopsy, and both ice-cold ethanol and bupivacaine prevented elevations in corticosterone and blood glucose after biopsy. Tail biopsy with or without anesthesia did not affect body weight or performance on elevated plus maze or open-field tests. We recommend the use of ice-cold ethanol for topical anesthesia prior to tail biopsy in mice 7 to 15 d old. PMID:27423152

2005-04-01

Type of thermal process [high temperature, short time pasteurization (HTST) or ultra-high temperature pasteurization (UHT)] and homogenization sequence (before or after pasteurization) were examined for influence on the physicochemical properties of natural cream (20% milk fat) and creams formulated with 20% low-melt, fractionated butteroil emulsified with skim milk, or buttermilk and butter-derived aqueous phase. Homogenization sequence influenced physicochemical makeup of the creams. Creams homogenized before pasteurization contained more milk fat surface material, higher phospholipid levels, and less protein at the milk fat interface than creams homogenized after pasteurization. Phosphodiesterase I activity was higher (relative to protein on lipid globule surface) when cream was homogenized before pasteurization. Creams formulated with skim milk and modified milk fat had relatively more phospholipid adsorbed at the milk fat interface. Ultra-high-temperature-pasteurized natural and reformulated creams were higher in viscosity at all shear rates investigated compared with HTST-pasteurized creams. High-temperature, short time-pasteurized natural cream was more viscous than HTST-pasteurized reformulated creams at most shear rates investigated. High-temperature, short time-pasteurized creams had better emulsion stability than UHT-pasteurized creams. Cream formulated with buttermilk had creaming stability most comparable to natural cream, and cream formulated with skim milk and modified butteroil was least stable to creaming. Most creams feathered in a pH range of 5.00 to 5.20, indicating that they were moderately stable to slightly unstable emulsions. All processing sequences yielded creams within sensory specifications with the exception of treatments homogenized before UHT pasteurization and skim milk formulations homogenized after UHT pasteurization.

A Tick Vector Transmission Model of Monocytotropic Ehrlichiosis

PubMed Central

Saito, Tais Berelli; Walker, David H.

2015-01-01

Background. Ehrlichioses are emerging, tick-borne diseases distributed worldwide. Previously established animal models use needle inoculation as a mode of infection; however, there is limited representation of natural transmission in artificially inoculated models compared with transmission by the tick vector. The objective of this study was to develop a tick vector transmission animal model of ehrlichial infection using a human pathogen, Ehrlichia muris–like agent (EMLA). Methods. Ixodes scapularis larvae were fed on EMLA-infected mice, and after molting, infected nymphs were used to infest naive animals. Results. Ehrlichiae were acquired by 90%–100% of feeding larvae. The majority of animals fed upon by infected nymphs developed sublethal infection with 27% lethality. Bacteria disseminated to all tissues tested with greatest bacterial loads in lungs, but also spleen, lymph nodes, liver, kidneys, brain, and bone marrow. Numerous foci of cellular infiltration, mitoses, and hepatocellular death were observed in liver. Mice infected by tick transmission developed higher antiehrlichial antibody levels than needle-inoculated animals. Tick-feeding-site reactions were observed, but there was no observed difference between animals infested with infected or uninfected ticks. Conclusions. For the first time we were able to develop a tick transmission model with an Ehrlichia that is pathogenic for humans. PMID:25737562

Evaluating sago as a functional ingredient in dietetic mango ice cream.

2010-10-01

A low fat mango ice cream (2.4% milk fat) was prepared in a mechanized 'ice and salt' type freezer using powdered sago at 2.5% as a natural bulking agent along with sodium alginate at 0.025% as adjunct. The low fat mango ice cream was compared with control mango ice cream having 10% milk fat and 0.15% sodium alginate as stabilizer. Both control as well as experimental ice creams contained 20% mango pulp solids. To impart richness to low fat mango ice cream, flavour enhancers like Cream Plus and Butter Buds were used at levels of 0.2% and 0.05%, respectively. The dietetic low fat ice creams compared well in sensory colour and appearance, flavour, body and texture, and melting quality to that of control ice cream. Incorporation of 2.5% powdered sago and 0.2% Cream Plus as flavour adjunct is recommended in the manufacture of 'low-fat' mango ice cream. The energy values for control and dietetic mango ice cream was 202.8 and 142.9 kcal/100 g, respectively, which represents about 30% reduction in calorie. The cost of ice cream per liter was Rs 39.9, Rs 37.6 and Rs 49.7 for experimental ice creams containing Cream Plus and Butter Bud, and control, respectively.

To determine if the use of hydrocortisone cream decreases perineal pain in the immediate postpartum period. This was a randomized controlled trial (RCT), crossover study design, with each participant serving as their own control. Participants received three different methods for perineal pain management at three sequential perineal pain treatments after birth: two topical creams (corticosteroid; placebo) and a control treatment (no cream application). Treatment order was randomly assigned, with participants and investigators blinded to cream type. The primary dependent variable was the change in perineal pain levels (posttest minus pretest pain levels) immediately before and 30 to 60 minutes after perineal pain treatments. Data were analyzed with analysis of variance, with p < 0.05 considered significant. A total of 27 participants completed all three perineal pain treatments over a 12-hour period. A reduction in pain was found after application of both the topical creams, with average perineal pain change scores of -4.8 ± 8.4 mm after treatment with hydrocortisone cream (N = 27) and -6.7 ± 13.0 mm after treatment with the placebo cream (N = 27). Changes in pain scores with no cream application were 1.2 ± 10.5 mm (N = 27). Analysis of variance found a significant difference between treatment groups (F2,89 = 3.6, p = 0.03), with both cream treatments having significantly better pain reduction than the control, no cream treatment (hydrocortisone vs. no cream, p = 0.04; placebo cream vs. no cream, p = 0.01). There were no differences in perineal pain reduction between the two cream treatments (p = .54). This RCT found that the application of either hydrocortisone cream or placebo cream provided significantly better pain relief than no cream application.

A new paradigm for the reversible blockage of whisker sensory transmission.

PubMed

Gener, Thomas; Reig, Ramon; Sanchez-Vives, Maria V

2009-01-30

The objective of this study was to explore a paradigm that would allow a temporary deprivation of whisker information lasting for a few hours. An additional requirement was to be non-invasive in order to be usable in awake chronically implanted rats without inducing stress. With that aim, electrophysiological recordings from the barrel cortex of anesthetized rats were obtained. The pressure of an air-puff (5-10 ms) delivered to the whiskers was adjusted to evoke a consistent response of around 100 microV (extracellular) or approximately 5 mV (intracellular) in the contralateral cortex. Lidocaine was then locally applied in different forms (cream, local injection, aerosol, drops) and concentrations (2-10%) to the base of the whiskers. The stimulus-induced response was monitored once every 5s for several hours (3-6h) in order to characterize its course of action. Local injection of lidocaine induced the fastest and most complete blockage, but was ruled out for being invasive. Out of the remaining forms of application, a lidocaine drop (0.4 ml, 10%) to the base of the whiskers was found to induce a reliable blockage (to an average 9% the original response). The maximum effect was reached after 150-200 min, and the response was totally recovered approximately 300 min after lidocaine application. This characterization should be useful to induce an efficient, short term and reversible blockage of whisker sensory transmission in both anesthetized and awake preparations, while not causing stress in an awake animal.

Ice cream, a popular product worldwide, is usually a milk-based product with other types of ingredients (fruit, eggs, cocoa, dried fruit, additives, and others). Different materials are used to obtain the desired taste, texture, consistency, and appearance of the final product. This study surveyed ice cream products available in Italy for heavy metals (lead, cadmium, chromium, tin, and arsenic). The differences between artisanal and industrial ice cream were also investigated because of the importance in the Italian diet and the diffusion of this ready-to-eat food. Ice cream sampling was performed between October 2010 and February 2011 in the northeast of Italy. A total of 100 samples were randomly collected from different sources: 50 industrial samples produced by 19 different brands were collected in coffee bars and supermarkets; 50 artisanal ice cream samples were gathered at nine different artisanal ice cream shops. Ten wooden sticks of industrial ice cream were analyzed in parallel to the ice cream. All samples were negative for arsenic and mercury. None of the artisanal ice cream samples were positive for lead and tin; 18% of the industrial ice cream samples were positive. All positive lead samples were higher than the legal limit stated for milk (0.02 mg/kg). All industrial ice cream samples were negative for cadmium, but cadmium was present in 10% of the artisanal ice cream samples. Chromium was found in 26% of the artisanal and in 58% of the industrial ice cream samples. The heavy metals found in the wooden sticks were different from the corresponding ice cream, pointing out the lack of cross-contamination between the products. Considering the results and the amount of ice cream consumed during the year, contamination through ice cream is a low risk for the Italian population, even though there is need for further analysis.

Herbal creams used for atopic eczema in Birmingham, UK illegally contain potent corticosteroids.

PubMed

Ramsay, H M; Goddard, W; Gill, S; Moss, C

2003-12-01

To determine whether "herbal creams" reported as being effective for the treatment of childhood atopic eczema contained corticosteroids. Patients attending the paediatric dermatology clinic at Birmingham Children's Hospital, April 2001 to March 2002, and who reported using "herbal creams" with good effect for atopic eczema were asked to submit the cream for analysis. Hydrocortisone, clobetasone butyrate, betamethasone valerate, and clobetasol propionate were analysed by HPLC. Twenty four creams from 19 patients, median (interquartile range) age 3.82 (0.69-7.98) years were analysed. All five creams labelled Wau Wa and the two labelled Muijiza cream contained clobetasol propionate. Thirteen of 17 unnamed creams contained corticosteroids: clobetasol proprionate (n = 4), clobetasol proprionate + hydrocortisone (n = 1), betamethasone valerate (n = 2), clobetasone butyrate (n = 3), and hydrocortisone (n = 2); there was an unidentified peak in one. Further analysis suggested Wau Wa cream contained approximately 20% proprietary Dermovate Cream in a paraffin base. No parents were aware that the creams contained steroid. The majority of herbal creams analysed illegally contained potent or very potent topical steroids. There is an urgent need for tighter regulation of herbal creams and for increased public education about the potential dangers of alternative therapies.

Effect of fat level on the perception of five flavor chemicals in ice cream with or without fat mimetics by using a descriptive test.

PubMed

Liou, B K; Grün, I U

2007-10-01

Fat mimetics are commonly used in the manufacture of low-fat and fat-free ice creams. However, the use of fat mimetics affects flavor and texture characteristics of ice cream, which results in decreased overall acceptability by consumers. The initial objective of this study was to investigate the release behavior of 5 strawberry flavor compounds in ice creams with Simplesse((R)), Litesse((R)), and Litesse((R))/Simplesse((R)) mixes using descriptive analysis. Fat mimetics and flavor formulation significantly influenced the perception of Furaneoltrade mark (cooked sugar flavor), alpha-ionone (violet flavor), and gamma-undecalactone (peach flavor), but there was no interaction between ice cream type and flavor formulation for the 3 flavors. Furaneol and ethyl-3-methyl-3-phenylglycidate (candy flavor) were perceived more strongly in full-fat ice cream, while cis-3-hexen-1-ol (grassy flavor), alpha-ionone, and gamma-undecalactone were perceived more strongly in low-fat ice cream. Ice creams with Simplesse and full-fat ice cream had similar sensory characteristics, while ice creams with Litesse were similar to low-fat ice creams in flavor characteristics, and ice creams with Litesse/Simplesse mixes were closer in flavor profile to low-fat ice cream but had similar texture properties to those of full-fat ice cream. Simplesse was found to be a better fat mimetic for duplicating the flavor profiles and mouthfeel of full-fat ice cream.

A survey of unopened ice cream, ice cream in use, and ice-cream-scoop water (n = 91) was conducted to determine the effect of scoop water hygiene on the microbiological quality of ice cream. An aerobic plate count around 10(6) c.f.u. ml-1 was the modal value for scoop waters. Unopened ice creams generally had counts around 10(3)-10(4) c.f.u. ml-1 and this increased by one order of magnitude when in use. Many scoop waters had low coliform counts, but almost half contained > 100 c.f.u. ml-1. E. coli was isolated in 18% of ice creams in use, and in 10% of unopened ice creams. S. aureus was not detected in any sample. Statistical analysis showed strong associations between indicator organisms and increased counts in ice cream in use. EC guidelines for indicator organisms in ice cream were exceeded by up to 56% of samples. PMID:9287941

A comparative study of the rheological and sensory properties of a petroleum-free and a petroleum-based cosmetic cream.

PubMed

Wang, Fan C; Marangoni, Alejandro G

A petroleum-free skin cream was developed using food-grade ingredients. The rheological and sensorial properties of this petroleum-free skin cream were compared to a commercially available petroleum-based skin cream. Specifically, large-amplitude oscillatory shear (LAOS) characterization of the two skin creams was performed. The petroleum-free skin cream showed similar linear and nonlinear viscoelastic rheological properties, comparable skin hydration functions, and consumer acceptance as the commercially available skin cream. A schematic diagram aiming to correlate the physical and sensorial properties of skin cream was also proposed at the end of the work. Results of this work could provide the cosmetic industry necessary information for the development of alternatives for petroleum-based skin creams.

Evaluation of the efficacy and tolerability of 0.5% fluorouracil cream and 5% fluorouracil cream applied to each side of the face in patients with actinic keratosis.

A new 0.5% fluorouracil cream has been developed that provides an alternative to the more highly concentrated topical formulations of fluorouracil that are currently available. This was a comparison of the tolerability and efficacy of the 0.5% and 5% fluorouracil creams in the treatment of actinic keratosis (AK). During this single-blind, randomized study, patients with > or =6 AK lesions were treated for 4 weeks with the 0.5% (once daily) and 5% (twice daily) fluorouracil creams applied to opposite sides of the face. After the end of treatment, patients were followed for an additional 4 weeks. Efficacy variables included absolute and percent reductions in AK lesions from baseline and total clearance of AK lesions. A questionnaire was used to evaluate patients' treatment preferences. Tolerability was evaluated through continuous monitoring of adverse events. Treatment with 0.5% fluorouracil cream reduced the number of AK lesions from 11.3 at baseline to 2.5 at the end of the 4-week follow-up phase, compared with a reduction from 10.3 to 4.2 lesions after treatment with 5% fluorouracil cream. The reduction was significantly greater with the 0.5% cream compared with the 5% cream (P = 0.044). The 0.5% cream was as effective as the 5% cream in terms of the percent reduction in AK lesions from baseline (67% and 47%, respectively) and in achieving total clearance of AK lesions (both treatments, approximately 43% of patients). Both treatments were associated with similar degrees of investigator-rated irritation; however, patients preferred the 0.5% cream because they felt it was more tolerable (P = 0.003), easier to apply, and had a once-daily application schedule. Although all patients experienced facial irritation in association with both creams, fewer patients treated with the 0.5% cream reported symptoms of facial irritation. In this study, 0.5% fluorouracil cream once daily was at least as effective as 5% fluorouracil cream twice daily in terms of the percent reduction in AK lesions and total clearance of AK lesions; it was more effective than the 5% cream in reducing the absolute number of AK lesions from baseline. Patients preferred the 0.5% cream to the 5% cream.

Olson, D W; White, C H; Watson, C E

2003-04-01

Sensory properties and rate of meltdown of nonfat (0% fat) and low-fat (2% fat) vanilla ice creams processed either by conventional valve homogenization or microfluidization of their mixes were compared with each other and to ice cream (10% fat) processed by conventional valve homogenization. Mixes for frozen dairy desserts containing 0, 2, and 10% fat were manufactured. Some of the nonfat and low-fat ice cream mixes were processed by microfluidization at 50, 100, 150, and 200 MPa, and the remaining nonfat and low-fat ice cream mixes and all of the ice cream mix were processed by conventional valve homogenization at 13.8 MPa, first stage, and 3.4 MPa, second stage. The finished frozen and hardened products were evaluated at d 1 and 45 for meltdown rate and for flavor and body and texture by preference testing. Nonfat and low-fat ice creams that usually had a slower meltdown were produced when processing their mixes by microfluidization instead of by conventional valve homogenization. Sensory scores for the ice cream were significantly higher than sensory scores for the nonfat and low-fat ice creams, but the sensory scores for the conventional valve homogenized controls for the nonfat ice cream and low-fat ice cream were not significantly different from the sensory scores for the nonfat ice cream and low-fat ice cream processed by microfluidization of the mixes, respectively. Microfluidization produced nonfat and low-fat ice creams that usually had a slower meltdown without affecting sensory properties.

Modern Grid middleware is built around components providing basic functionality, such as data storage, authentication, security, job management, resource monitoring and reservation. In this paper we describe the Computing Resource Execution and Management (CREAM) service. CREAM provides a Web service-based job execution and management capability for Grid systems; in particular, it is being used within the gLite middleware. CREAM exposes a Web service interface allowing conforming clients to submit and manage computational jobs to a Local Resource Management System. We developed a special component, called ICE (Interface to CREAM Environment) to integrate CREAM in gLite. ICE transfers job submissions and cancellations from the Workload Management System, allowing users to manage CREAM jobs from the gLite User Interface. This paper describes some recent studies aimed at assessing the performance and reliability of CREAM and ICE; those tests have been performed as part of the acceptance tests for integration of CREAM and ICE in gLite. We also discuss recent work towards enhancing CREAM with a BES and JSDL compliant interface.

Sour cream is a widely popular acidified dairy product. Volatile compounds and organic acids and their specific contributions to flavor or acceptance have not been established, nor has a comprehensive study been conducted to characterize drivers of liking for sour cream. The objective of this study was to characterize chemical and sensory properties of sour cream and to determine the drivers of liking for sour cream. Descriptive sensory and instrumental analyses followed by consumer testing were conducted. Flavor and texture attributes of 32 (22 full-fat, 6 reduced-fat, and 4 fat-free) commercial sour creams were evaluated by a trained descriptive sensory panel. Percent solids, percent fat, pH, titratable acidity, and colorimetric measurements were conducted to characterize physical properties of sour creams. Organic acids were evaluated by HPLC and volatile aroma active compounds were evaluated by gas chromatography-mass spectrometry with gas chromatography-olfactometry. Consumer acceptance testing (n=201) was conducted on selected sour creams, followed by external preference mapping. Full-fat sour creams were characterized by the lack of surface gloss and chalky textural attributes, whereas reduced-fat and fat-free samples displayed high intensities of these attributes. Full-fat sour creams were higher in cooked/milky and milk fat flavors than the reduced-fat and fat-free samples. Reduced-fat and fat-free sour creams were characterized by cardboard, acetaldehyde/green, and potato flavors, bitter taste, and astringency. Lactic acid was the prominent organic acid in all sour creams, followed by acetic and citric acids. High aroma-impact volatile compounds in sour creams were 2,3-butanedione, acetic acid, butyric acid, octanal, 2-methyl-3-furanthiol, 1-octene-3-one, and acetaldehyde. Positive drivers of liking for sour cream were milk fat, cooked/milky and sweet aromatic flavors, opacity, color intensity, and adhesiveness. This comprehensive study established sensory and instrumental properties of sour creams and their relationship to consumer acceptance. Copyright © 2013 American Dairy Science Association.

Development of technology for manufacture of ragi ice cream.

PubMed

Patel, I J; Dharaiya, C N; Pinto, S V

2015-07-01

Ragi (Finger millet) improves the nutritional value of ice cream by enhancing the iron and fibre content. Caramel flavoured medium fat ice cream (6 % fat) was prepared by addition of gelatinized malted ragi flour roasted in butter (MRB) @ 8 %, 9 % and 10 % by weight of mix and compared with control (C) i.e. vanilla ice cream containing 10 % fat. The overall acceptability score of product prepared using 9 % MRB was statistically (P > 0.05) at par with the C, hence, it was selected. In the next part of the study, ragi ice cream was prepared using 4 different flavours viz. vanilla, mango, chocolate and caramel. Chocolate flavoured ragi ice cream was adjudged as best, followed by mango, caramel and vanilla ice cream. The iron and fibre content of chocolate flavoured ragi ice cream was found to be 12.8 ppm and 1.36 % respectively. vs. 1.5 ppm and 0.18 % respectively in control (C). Heat shock treatment as well as storage up to 30 days had no adverse effect on the sensory quality of the chocolate flavored ragi ice cream. Incorporation of finger millet in ice cream resulted in reduction in the amount of stabilizer used and effectively functioned as fat replacer in ice cream.

Ice cream structural elements that affect melting rate and hardness.

PubMed

Muse, M R; Hartel, R W

2004-01-01

Statistical models were developed to reveal which structural elements of ice cream affect melting rate and hardness. Ice creams were frozen in a batch freezer with three types of sweetener, three levels of the emulsifier polysorbate 80, and two different draw temperatures to produce ice creams with a range of microstructures. Ice cream mixes were analyzed for viscosity, and finished ice creams were analyzed for air cell and ice crystal size, overrun, and fat destabilization. The ice phase volume of each ice cream were calculated based on the freezing point of the mix. Melting rate and hardness of each hardened ice cream was measured and correlated with the structural attributes by using analysis of variance and multiple linear regression. Fat destabilization, ice crystal size, and the consistency coefficient of the mix were found to affect the melting rate of ice cream, whereas hardness was influenced by ice phase volume, ice crystal size, overrun, fat destabilization, and the rheological properties of the mix.

Production of functional probiotic, prebiotic, and synbiotic ice creams.

2010-10-01

In this work, 3 types of ice cream were produced: a probiotic ice cream produced by adding potentially probiotic microorganisms such as Lactobacillus casei and Lactobacillus rhamnosus; a prebiotic ice cream produced by adding inulin, a prebiotic substrate; and a synbiotic ice cream produced by adding probiotic microorganisms and inulin in combination. In addition to microbial counts, pH, acidity, and physical and functional properties of the ice creams were evaluated. The experimental ice creams preserved the probiotic bacteria and had counts of viable lactic acid bacteria after frozen storage that met the minimum required to achieve probiotic effects. Moreover, most of the ice creams showed good nutritional and sensory properties, with the best results obtained with Lb. casei and 2.5% inulin. Copyright © 2010 American Dairy Science Association.

Rheological properties of ice cream mixes and frozen ice creams containing fat and fat replacers.

PubMed

Adapa, S; Dingeldein, H; Schmidt, K A; Herald, T J

2000-10-01

Ice cream mixes and frozen ice creams at milk fat levels of 12%, 8%, 6%, 6% plus a protein-based fat replacer, and 6% plus a carbohydrate-based fat replacer were evaluated for viscoelastic properties by dynamic testing with sinusoidal oscillatory tests at various frequencies. The storage modulus (G'), loss modulus (G"), and tan delta (G"/G') were calculated for all the treatments to determine changes in the viscous and elastic properties of the mixes and frozen ice creams due to fat content. In ice cream mixes, G' and G" exhibited a strong frequency dependence. The G" was higher than G' throughout the frequency range (1 to 8 Hz) examined, without any crossover, except for the 12% mix. Elastic properties of the ice cream mixes decreased as fat content decreased. Tan delta values indicated that fat replacers did not enhance the elastic properties of the ice cream mixes. In all frozen ice creams, G' and G" again showed a frequency dependence throughout the range tested (0.5 to 10 Hz). The amount of fat in ice creams and the degree of fat destabilization affected the elasticity in the frozen product. Even though the ice creams did not have significant elastic properties, when compared as a group the samples with higher fat content had higher elastic properties. The addition of protein-based and carbohydrate-based fat replacers did not enhance the elastic properties of the ice creams but did increase the viscous properties.

Determination of ultraviolet filter activity on coconut oil cosmetic cream

NASA Astrophysics Data System (ADS)

Widiyati, Eni

2017-08-01

A research on determination of ultraviolet (UV) filter activity of cosmetic cream with coconut oil as raw material has been done. The cream was made by mixing the oil phase (coconut oil, stearic acid, lanolin and cetyl alcohol) at 70°C and the water phase (glycerin, aquadest and triethanolamine) at 70°C, while stirring until reached a temperature of 35°C. It was made also a cream with inorganic sunscreen TiO2 and organic sunscreen benzophenone-3 as a comparison. To study the UV filter activity, each cream was determined the UV absorption using UV spectrophotometer. The results show that cosmetic cream with coconut oil as raw material absorbs UV rays in the region of UV-C, whereas the cream with TiO2 absorbs the UV rays from UV-C to UV-A and cream with benzophenone-3 absorbs the UV rays from UV-B to UV-A region. This means that, the cosmetic cream with coconut oil as raw material has an activity as UV-C filter. If this cream is expected to have an activity as a sunscreen, it must be added an inorganic or organic sunscreen or a mixture of both as an active materials.

High hydrostatic pressure modification of whey protein concentrate for improved body and texture of lowfat ice cream.

PubMed

Lim, S-Y; Swanson, B G; Ross, C F; Clark, S

2008-04-01

Previous research demonstrated that application of high hydrostatic pressure (HHP), particularly at 300 MPa for 15 min, can enhance foaming properties of whey protein concentrate (WPC). The purpose of this research was to determine the practical impact of HHP-treated WPC on the body and texture of lowfat ice cream. Washington State University (WSU)-WPC was produced by ultrafiltration of fresh separated whey received from the WSU creamery. Commercial whey protein concentrate 35 (WPC 35) powder was reconstituted to equivalent total solids as WSU-WPC (8.23%). Three batches of lowfat ice cream mix were produced to contain WSU-WPC without HHP, WSU-WPC with HHP (300 MPa for 15 min), and WPC 35 without HHP. All lowfat ice cream mixes contained 10% WSU-WPC or WPC 35. Overrun and foam stability of ice cream mixes were determined after whipping for 15 min. Ice creams were produced using standard ice cream ingredients and processing. The hardness of ice creams was determined with a TA-XT2 texture analyzer. Sensory evaluation by balanced reference duo-trio test was carried out using 52 volunteers. The ice cream mix containing HHP-treated WSU-WPC exhibited the greatest overrun and foam stability, confirming the effect of HHP on foaming properties of whey proteins in a complex system. Ice cream containing HHP-treated WSU-WPC exhibited significantly greater hardness than ice cream produced with untreated WSU-WPC or WPC 35. Panelists were able to distinguish between ice cream containing HHP-treated WSU-WPC and ice cream containing untreated WPC 35. Improvements of overrun and foam stability were observed when HHP-treated whey protein was used at a concentration as low as 10% (wt/wt) in ice cream mix. The impact of HHP on the functional properties of whey proteins was more pronounced than the impact on sensory properties.

Ice cream structure modification by ice-binding proteins.

2018-04-25

Ice-binding proteins (IBPs), also known as antifreeze proteins, were added to ice cream to investigate their effect on structure and texture. Ice recrystallization inhibition was assessed in the ice cream mixes using a novel accelerated microscope assay and the ice cream microstructure was studied using an ice crystal dispersion method. It was found that adding recombinantly produced fish type III IBPs at a concentration 3 mg·L -1 made ice cream hard and crystalline with improved shape preservation during melting. Ice creams made with IBPs (both from winter rye, and type III IBP) had aggregates of ice crystals that entrapped pockets of the ice cream mixture in a rigid network. Larger individual ice crystals and no entrapment in control ice creams was observed. Based on these results a model of ice crystals aggregates formation in the presence of IBPs was proposed.

2015-07-01

The effect of the addition of galactooligosaccharide (GOS) on the physicochemical, optical, and sensory characteristics of ice cream was investigated. Vanilla ice cream was supplemented with 0, 1.5, and 3.0% (wt/wt) GOS and characterized for pH, firmness, color, melting, overrun, as well as subjected to a discriminative sensory test (triangle test). For comparison purposes, ice creams containing fructooligosaccharide were also manufactured. The GOS ice creams were characterized by increased firmness and lower melting rates. Different perceptions were reported in the sensory evaluation for the 3.0% GOS ice cream when compared with the control, which was not observed for the fructooligosaccharide ice cream. Overall, the findings suggest it is possible to produce GOS ice cream with improved stability in relation to the physicochemical parameters and sensory perception.

2017-09-01

Observational studies of Mesem cream (based on Mesembryanthemum crystallinum L. plant extract) found that it had positive effects on skin hydration and smoothing of the skin. However, some patients reported skin irritation effects. The current study evaluated the skin tolerability of Mesem cream, as compared to the carrier cream (without the active ingredient), by using the isolated perfused bovine udder skin model. The primary outcomes investigated were cytotoxicity (i.e. cell viability), assessed with the MTT assay, and irritancy and inflammation, assessed by measuring PGE₂ tissue levels. A total reaction score was calculated by combining the results for each parameter. In the case of a single topical application, significant differences were found between the carrier cream and the Mesem cream. While the application of carrier cream resulted in low cytotoxicity (-8.4% change in viability, as compared to the untreated control), the Mesem cream was more cytotoxic (-18.7% change). In addition, one hour after application, PGE₂ levels were higher in Mesem cream-treated skin, as compared to carrier cream-treated skin (16.6% versus 11.3%). Further experiments (tape-stripped skin and repeated application) also found significant differences between the two creams in the results obtained. Evaluation of the effectiveness, safety and tolerability of phyto-cosmetic products is important. Our results confirmed the findings of two previous human observational studies (the human patch test and open application study). Future experiments to understand the underlying principles of its effectiveness, safety and tolerability should include extracts of M. crystallinum L. juice, as well as the Mesem cream itself. 2017 FRAME.

Influence of nanostructured lipid carriers (NLC) on the physical properties of the Cutanova Nanorepair Q10 cream and the in vivo skin hydration effect.

Pardeike, Jana; Schwabe, Kay; Müller, Rainer H

2010-08-30

Cutanvoa Nanorepair Q10 cream, the first NLC containing cosmetical product introduced to the market in October 2005, was compared to an identical o/w cream without NLC with regards to particle size, melting behaviour, rheological properties and the in vivo effect on skin hydration. The consistency, the spreadability on the skin and the subjective feeling of increase in skin hydration were evaluated using a standardized questionnaire, and compared to hydration data measured. Furthermore, it was shown by epicutaneous patch test that Cutanova Nanorepair Q10 cream has no irritating effects on the skin. By laser diffraction (LD) and differential scanning calorimetry (DSC) measurements it could be shown that NLC are physically stable in Cutanova Nanorepair Q10 cream. After 7 days application of Cutanova Nanorepair Q10 cream and NLC negative control cream an increase in skin hydration could be objectively confirmed by measurements in vivo. From day 28 on the skin hydration measured in the test areas of Cutanova Nanorepair Q10 cream was significantly higher than the skin hydration in the test areas of the NLC negative control cream (p=0.05). The subjective feeling of increase in skin hydration was also rated from the volunteers as superior for Cutanova Nanorepair Q10 cream. The rheological properties of Cutanova Nanorepair Q10 cream contributed to a better subjective impression of consistency and spreadability on the skin than found for NLC negative control cream.

Essential oil of Syzigium aromaticum has been formulated in O/W and W/O creams as anti-inflammatory dosage form. The purpose of this study was to evaluate the physical characteristic and irritation index of S. aromaticum essential oil in O/W and W/O creams. The creams were made by fusion method. The creams then were evaluated the physical characteristic including pH, viscosity, spreadability and adhesivity. The irritation index was obtained by irritation skin test in male rabbit. The results showed that the W/O and O/W creams have the value of pH: 6.3 and 6.27; spreadability: 3,18 and 4.17 cm2; adhesivity: 5.59 and 0.07 minutes; viscosity: 4.43 and 2.88 Pa.S, respectively. The irritation test showed that the control enhancer caused mild irritation in both of W/O and O/W creams. These findings indicated that type of cream might influence the physical characteristic and irritation index of S. aromaticum essential oil cream.

A ready to use food such as instant cream soup become the most suitable choice for those who prefer being practical and also can be applied in any emergency situation such as areas affected by disaster. The adding of milk powder as the main ingredient in cream soup creates a complex bounding of fat and starch which complicates the rehydration process and affects other physical appearance. This research was aimed to find the proper concentration of full cream milk powder concentration to obtain the best characteristics of instant cream soup of dried sweet potato puree. The method used in this research was randomized block design with 6 treatments (12.5%, 15%, 17.5%, 20%, 22.5% and 25%, with an addition of full cream milk powder) and twice repetition. Instant cream soup with 20% of full cream milk powder concentration gave the best physical and chemical characteristics. The physical and chemical characteristic shows that it has 6% water content, 95.47% rehydration value, 18% protein, 20.7% fat, 1080.25 cP viscosity and 30.5% rendement.

In the search for the ideal dithranol cream preparation for short-contact treatment of psoriasis, we investigated the clinical efficacy, side effects and patient appreciation of two dithranol cream preparations (cream A and B) in a double-blind left-right comparing study. Dithranol was dissolved at preparation in cream A and dispersed in cream B. Cream A is known to have a shelf life of 1 year, while cream B has a much shorter shelf life (several months). Ten patients with chronic plaque-type psoriasis were treated during 7 weeks in a short-contact regimen. The clinical efficacy was monitored by scoring of erythema, induration, scaling and involved area (PASI); skin irritation was scored visually, and patient appreciation was evaluated by means of a multiple-choice questionnaire. Dispersion of dithranol in a cream was associated with less irritation and less discoloration of the skin, and its efficacy was comparable with that of the cream in which the dithranol was dissolved. As the dispersed dithranol formulation is easier to be manufactured, its quality will be less depending on the pharmacist's experience and equipment, and so more reliable. Besides, it will be less expensive to prepare. We advise to use this formulation for short-contact treatment. Copyright 2000 S. Karger AG, Basel.

An analysis of at-home demand for ice cream in the United States.

Davis, C G; Blayney, D P; Yen, S T; Cooper, J

2009-12-01

Ice cream has been manufactured commercially in the United States since the middle of the 19th century. Ice cream and frozen dessert products comprise an important and relatively stable component of the United States dairy industry. As with many other dairy products, ice cream is differentiated in several dimensions. A censored translog demand system model was employed to analyze purchases of 3 ice cream product categories. The objective of this study was to determine the effect that changes in retail prices and consumer income have on at-home ice cream consumption. The analysis was based on Nielsen 2005 home scan retail data and used marital status, age, race, education, female employment status, and location in the estimations of aggregate demand elasticities. Results revealed that price and consumer income were the main determinants of demand for ice cream products. Calculated own-price elasticities indicated relatively elastic responses by consumers for all categories except for compensated bulk ice cream. All expenditure elasticities were inelastic except for bulk ice cream, and most of the ice cream categories were substitutes. Ongoing efforts to examine consumer demand for these products will assist milk producers, dairy processors and manufacturers, and dairy marketers as they face changing consumer responses to food and diet issues.

2016-10-01

In this work, we developed a wound healing cream composed of two different polymers, namely chitosan and gelatin with chlorhexidine along with calcium phosphate nanoparticles. The physicochemical properties of the prepared cream were investigated based on SEM, EDX, Raman, FTIR and the results indicated that the cream contained gelatin, chitosan, calcium phosphate nanoparticles and chlorhexidine. The maximum swelling ratio studies indicated that the ratio was around of 52±2.2 at pH7.4 and the value was increased in acidic and alkaline pH. The antimicrobial activity was tested against bacteria and the results indicated that, both chlorhexidine and the hybrid cream devoid of chlorhexidine exhibited antimicrobial activity but the chlorhexidine impregnated cream showed three fold higher antimicrobial activity than without chlorhexidine. In vivo wound healing promoting activities of hybrid cream containing 0.4mg/L chlorhexidine were evaluated on surgically induced dermal wounds in mice. The results indicated that the cream with incorporated chlorhexidine significantly enhanced healing compared with the control samples. For the field validations, the veterinary clinical animals were treated with the cream and showed enhanced healing capacity. In conclusion, a simple and efficient method for design of a novel wound healing cream has been developed for veterinary applications. Copyright © 2016 Elsevier B.V. All rights reserved.

The purpose of this work was to develop an effective carbomer hydrogel to be used to treat second-degree burns that combined ciprofloxacin and lidocaine (CbCipLid hydrogel). Its antibiotic and anesthetic efficacy and the physical and chemical properties of the CbCipLid hydrogel (release rate and kinetics, rheology, appearance, and drug content) were evaluated both before and after a sterilization cycle and also after 6 months of storage. For the in vivo studies, second-degree burns were developed in a rat model. Animals were divided into three groups: CbCipLid hydrogel, silver sulfadiazine cream (reference), and carbomer hydrogel (as control). The treatments were applied daily for 21 days, and the healing was monitored by macroscopic observation and histologic evaluation. The anesthetic effect was evaluated through the corneal touch threshold in a rabbit eye model. The CbCipLid hydrogel obtained is transparent and allows the loading of ciprofloxacin above its solubility at a neutral pH, with a rheology which is convenient for topical administration. Its physical and chemical properties remained unchanged after sterilization and for at least six additional months. Both ciprofloxacin and lidocaine are reversibly released from the CbCipLid hydrogel with a kinetics fitting the Higuchi model. The presence of a biologic-like fluid increased the rate of drug delivery through an ionic exchange mechanism. Treatment with the CbCipLid hydrogel decreased the wound-healing period, compared with the reference, and was associated with a greater number of fibroblasts and a faster rate of epithelialization and dermis reconstruction. These differences were assigned to the moist environment provided by the hydrogel and also to the presence of a therapeutic concentration of ciprofloxacin. Moreover, CbCipLid hydrogel provides an immediate anesthetic effect, which is significantly more intense than that of the reference. Based on these results, it is believed that the CbCipLid hydrogel could be a potential candidate in the prophylaxis/treatment of second-degree burns.

Ergonomics investigation of retail ice cream operations.

PubMed

Dempsey, P G; McGorry, R R; Cotnam, J; Braun, T W

2000-04-01

A comprehensive ergonomics evaluation of retail ice cream shops, including field and laboratory data collection, was conducted using a human:workplace model approach to ergonomics practice. The goal of the evaluation was to provide recommendations to enhance the health, safety, and productivity of shop employees. Active and passive surveillance and facility walk-throughs were used to guide the selection of analyses. A primary focus of the investigation was quantifying the task demands of scooping ice cream, which have not been documented in the literature. This goal was accomplished through the use of a custom-designed instrumented ice cream scoop. Data were collected at an ice cream shop under typical conditions, while the laboratory experiment investigated task demands of ice cream scooping over a range of realistic temperatures. Manual materials handling task analyses and anthropometric evaluations comprised the majority of other analyses performed. Recommendations are presented that are applicable to the operation of retail ice cream shops that serve hard (i.e., scooped) ice cream.

Effect of the fat globule sizes on the meltdown of ice cream.

PubMed

Koxholt, M M; Eisenmann, B; Hinrichs, J

2001-01-01

The meltdown of ice cream is influenced by its composition and additives and by fat globule size. The objective of this study was to examine the effect of fat globule size and fat agglomerate size on the meltdown stability of ice cream. Therefore, an ice cream mix (10% milk fat) was homogenized at pressures ranging from 0 to 30 MPa in single-stage, double-stage, and selective homogenization processes. The ice cream, produced on a continuous ice cream freezer, was characterized by an optimized meltdown test while, in addition, the fat globule sizes and the free fat content were determined in the mix and the molten ice cream. The meltdown was dependent on the fat agglomerate sizes in the unfrozen serum phase. Agglomerates smaller than a critical diameter led to significantly higher meltdown rates. Homogenization pressures of at least 10 MPa were sufficient to produce a stable ice cream. Furthermore, proof was provided that double-stage homogenization is not necessary for fat contents up to 10% and that selective homogenization is possible to produce stable ice creams. Based on these results a model was deduced describing the stabilizing mechanisms during the meltdown process.

Effect of storage temperature on quality of light and full-fat ice cream.

PubMed

Buyck, J R; Baer, R J; Choi, J

2011-05-01

Ice cream quality is dependent on many factors including storage temperature. Currently, the industry standard for ice cream storage is -28.9 °C. Ice cream production costs may be decreased by increasing the temperature of the storage freezer, thus lowering energy costs. The first objective of this research was to evaluate the effect of 4 storage temperatures on the quality of commercial vanilla-flavored light and full-fat ice cream. Storage temperatures used were -45.6, -26.1, and -23.3 °C for the 3 treatments and -28.9 °C as the control or industry standard. Ice crystal sizes were analyzed by a cold-stage microscope and image analysis at 1, 19.5, and 39 wk of storage. Ice crystal size did not differ among the storage temperatures of light and full-fat ice creams at 19.5 or 39 wk. An increase in ice crystal size was observed between 19.5 and 39 wk for all storage temperatures except -45.6 °C. Coldness intensity, iciness, creaminess, and storage/stale off-flavor of the light and full-fat ice creams were evaluated at 39 wk of storage. Sensory evaluation indicated no difference among the different storage temperatures for light and full-fat ice creams. In a second study, light and full-fat ice creams were heat shocked by storing at -28.9 °C for 35 wk and then alternating between -23.3 and -12.2 °C every 24h for 4 wk. Heat-shocked ice creams were analyzed at 2 and 4 wk of storage for ice crystal size and were evaluated by the sensory panel. A difference in ice crystal size was observed for light and full-fat ice creams during heat-shock storage; however, sensory results indicated no differences. In summary, storage of light or full-fat vanilla-flavored ice creams at the temperatures used within this research did not affect quality of the ice creams. Therefore, ice cream manufacturers could conserve energy by increasing the temperature of freezers from -28.9 to -26.1 °C. Because freezers will typically fluctuate from the set temperature, usage of -26.1 °C allows for a safety factor, even though storage at -23.3 °C did not affect ice cream quality.

Investigation on the photostability of tretinoin in creams.

PubMed

Brisaert, M; Plaizier-Vercammen, J A

2007-04-04

In this investigation, the photodegradation of some tretinoin cream formulations was evaluated. Several oils were selected to prepare the cream formulations: olive oil, maize oil, castor oil, isopropyl myristate and Miglyol 812. A solubility study showed that tretinoin is best soluble in castor oil (0.60g/100ml), followed by isopropyl myristate, maize oil, Miglyol 812 and olive oil, respectively, 0.35, 0.30, 0.29 and 0.22g/100ml. The photostability of tretinoin in oils is comparable with the photostability of a tretinoin lotion (ethanol/propylene glycol 50/50), castor oil and olive oil giving slightly better results than the other oils. Investigation of the photodegradation of tretinoin in o/w creams, prepared with the same oils as mentioned above, revealed that tretinoin is far more stable in the cream formulations than in the respective oils, however it is not clear whether this is due to the formulation or due to a different irradiation technique. Tretinoin seemed to be most stable in the olive oil cream, followed by the castor oil cream. However microscopic investigation revealed the presence of tretinoin crystals in the olive oil cream, while the other creams were free of it. As a conclusion, one can say that the cream prepared with castor oil seems to be the most suitable one, in terms of solubility of tretinoin and in terms of photostability.

Topical application of timolol cream is effective and convenient for treating superficial infantile hemangiomas. Intralesional injection of corticosteroids, such as diprospan, is useful for the treatment of superficia infantile hemangiomas without systemic side effects. We conducted a self-controlled study to investigate whether a combination of intralesional injection of diprospan with topical timolol 0.5% cream would be more efficient than timolol cream alone in thick superficial infantile hemangiomas. Thirty-eight patients with 39 thick superficial infantile hemangiomas were recruited. Each lesion was randomly divided into two equal parts: one part was treated with topical timolol 0.5% cream (timolol cream group), while the other part was treated with injection of diprospan combined with topical timolol 0.5% cream (combined treatment group). Infants were followed every 4 weeks to determine whether injections should be continued, and timolol cream was applied four times daily for 5 months. During 5 months of treatment, three specialist physicians were invited to evaluate the therapeutic effects. The combined treatment group showed better lesion involution than did the timolol cream group regarding lesion thickness and color of lesions. The combination of intralesional injection of diprospan with topical timolol 0.5% cream is a suitable and safe strategy for thick superficial infantile hemangiomas. © 2018 Wiley Periodicals, Inc.

2010-02-01

To optimize the formula of Glycyrrhiza flavonoid and ferulic acid cream and set up its quality control parameters. Reflect-line orthogonal simplex method was used to optimize the main factors such as amount of Myrj52-glyceryl monostearate and dimethicone, based on the appearance, spreadability and stability of the cream. 9.0% Myrj52-glyceryl monostearate (3:2) and 2.5% dimethicone were chosen in prescription. The prepared cream presented a good stability after being placed 24 h at 5 degrees C, 25 degrees C and 37 degrees C respectively,and its spreadability suited with the property of semi-fluid cream. [corrected] The formula of Glycyrrhiza flavonoid and ferulic acid cream is suitable, and its quality is stable. The reflect-line orthogonal simplex method is suitable for the formula optimization of cream.

2010-02-01

In this study, 809 samples of ice cream from different sources were investigated by using cultural methods for the presence of presumptive Bacillus cereus. Isolates from culture-positive samples were examined with a real-time PCR assay targeting a region of the cereulide synthetase gene (ces) that is highly specific for emetic B. cereus strains. The samples were collected from ice cream parlors and restaurants that produced their own ice cream and from international commercial ice cream companies in different regions of Bavaria during the summer of 2008. Presumptive B. cereus was found in 508 (62.7%) ice cream samples investigated, and 24 (4.7%) of the isolates had the genetic background for cereulide toxin production. The level of emetic B. cereus in the positive samples ranged from 0.1 to 20 CFU/g of ice cream.

Rheological properties of reduced fat ice cream mix containing octenyl succinylated pearl millet starch.

PubMed

Sharma, Monika; Singh, Ashish K; Yadav, Deep N

2017-05-01

The octenyl succinyl anhydride (OSA) esterified pearl millet ( Pennisetum typhoides ) starch was evaluated as fat replacer in soft serve ice cream in comparison to other fat replacers viz. inulin, whey protein concentrate-70 and commercial starch. During temperature sweep test, the yield stress and flow behaviour index of un-pasteurized ice cream mixes increased as the temperature increased from 40 to 80 °C, while the consistency index decreased. Consistency index of aged ice cream mixes containing 2% fat replacer was higher as compared to mixes with 1% level. The aged ice cream mixes exhibited non-Newtonian behaviour as flow behaviour index values were less than one. Apparent viscosity (at 50 s -1 shear rate) of control as well as ice cream mix containing 1% OSA-esterified pearl millet starch samples was 417 and 415 mPas, respectively and did not differ significantly. The overrun of the ice cream (with 5 and 7.5% fat) containing 1 and 2% of above fat replacers ranged between 29.7 and 34.3% and was significantly lower than control (40.3%). The percent melted ice cream was also low for the ice creams containing 2% of above fat replacers at 5% fat content as compared to control. However, sensory acceptability and rheological characteristics of reduced fat ice creams containing 1.0 and 2.0% OSA-esterified pearl millet starch were at par with other fat replacers under the study. Thus, OSA-esterified pearl millet starch has potential to be used as fat replacer in reduced fat ice cream.

2014-11-01

This work was carried out to study the nutritional quality of milk of cows fed palm oil (PAL) or coconut fat (COC), and the use of that milk as raw material for ice cream production. Three treatments were tested with 23 healthy cows: control (CON), PAL, and COC. The milk was collected at d 21 and 36 of the experimental diet. Proximate composition (moisture, ash, fat, protein, and carbohydrates) and fatty acid composition were evaluated on milk and ice cream, and sensorial analysis, color (lightness, green/red, and blue/yellow), overrun, and texture were evaluated on the ice cream. Fatty acids present in milk and ice cream were determined by gas chromatography. Sensory analysis results showed that the ice cream acceptability index was above 70%. No difference was observed for proximate composition in milk and ice cream. Chromatographic analysis showed an increase in saturated fatty acid concentration in CON and lower levels in PAL; polyunsaturated fatty acid concentration was higher in PAL and lower in CON, in milk and ice cream; monounsaturated fatty acid concentration in milk was higher in PAL and lower in CON but no difference was found in ice cream. Comparing n-3 content in milk and ice cream, we observed that PAL had higher levels than CON and COC. The results indicate that it is feasible to add sources of fat to the animal feed for fatty acid composition modulation of milk and ice cream. Copyright © 2014 American Dairy Science Association.

Kaur, Chanchal Deep; Saraf, Swarnlata

2011-12-01

  Ultraviolet radiations generate reactive oxygen species, leading to adverse effects on skin properties. Botanical extracts are multifunctional in nature having various properties like photoprotection, anti-aging, moisturizing, antioxidant, astringent, anti-irritant, and antimicrobial activity.   The aim of this study was to formulate creams having Curcuma longa extract loaded novel vesicular systems (liposomes, ethosomes, and transfersomes) and study their photoprotective effect by assessment of skin hydration (Cutometer) and sebum content (Sebumeter).   The alcoholic C. longa extract loaded liposomes, ethosomes, and transfersomes having 0.5-2.0% w/w extract were prepared, evaluated for size, entrapment efficiency, and incorporated into the cream. Their long-term interaction with skin (6 weeks) was compared in terms of their effects on skin hydration and sebum content.   Vesicular size obtained was in the range 167.3 ± 3.0 to 262.4 ± 2.4 nm with low polydispersity index (0.2-0.3) and high entrapment efficiency. The efficacy was in the order C. longa extract loaded transfersomal creams > C. longa extract loaded ethosomal creams > C. longa extract loaded liposomal creams > C. longa extract loaded creams > Empty transfersome loaded cream > Empty ethosome loaded cream > Empty liposome loaded cream > Base cream.   The photoprotective properties of the constituents of C. longa extract and hydrant, moisturizing lipid components of nano vesicles with better skin penetration resulted in improvement in skin properties like skin hydration and sebum content. The herbal extract loaded nano vesicles incorporated in cream could be used as photoprotective formulations. © 2011 Wiley Periodicals, Inc.

2010-05-01

In the present project, Solid Lipid Nanoparticles (SLNs) bearing oxybenzone were prepared by ethanol injection method to improve its effectiveness as sunscreen. SLNs were characterized for particle size,polydispersity index, zeta potential and surface morphology. The optimized SLNs bearing oxybenzone were incorporated into water-removable cream base and compared with SLNs unloaded water-removable cream base for in vitro and in vivo parameters. Cream base formulation containing SLNs (Csd) with 5% oxybenzone showed slow drug release and better sun protecting factor (more than 25) compared to cream base containing 5% oxybenzone. Confocal Laser Scanning Microscopy was used to visualize the distribution of developed formulations in skin. CLSM indicated prolonged retention of SLNs in the stratum corneum as compared to plain cream base. These studies revealed that the cream base bearing SLNs exhibited good skin retention as well as enhanced sun protection effect compared to cream base.

Ignoring small predictable profits and losses: a new approach for measuring incentives for cream skimming.

PubMed

van Barneveld, E M; Lamers, L M; van Vliet, R C; van de Ven, W P

2000-02-01

Under inadequate capitation formulae competing health insurers have an incentive for cream skimming, i.e., the selection of enrollees whom the insurer expects to be profitable. When evaluating different capitation formulae, previous studies used various indicators of incentives for cream skimming. These conventional indicators are based on all actual profits and losses or on all predictable profits and losses. For the latter type of indicators, this paper proposes, as a new approach, to ignore the small predictable profits and losses. We assume that this new approach provides a better indication of the size of the cream skimming problem than the conventional one, because an insurer has to take into account its costs of cream skimming and the (statistical) uncertainties about the net benefits of cream skimming. Both approaches are applied in theoretical and empirical analyses. The results show that, if our assumption is right, the problem of cream skimming is overestimated by the conventional ways of measuring incentives for cream skimming, especially in the case of relatively good capitation formulae.

In this study, the possible effects of zinc on physicochemical properties of ice cream and the survival of Lactobacillus casei during a 90 days storage at -18°C was investigated. Samples were divided into four experimental groups as follows: control, zinc fortified ice cream, probiotic ice cream, zinc fortified and probiotic ice cream. The physicochemical, texture, organoleptic properties and the survival of probiotics, were investigated. Results showed that the addition of zinc did not affect the textural properties of ice creams. Viscosity and pH were independently decreased in all groups in the presence of zinc. A significant increase in the lipid oxidation rate especially in the zinc fortified group was also observed. The probiotic counts were maintained above the least advised quantities (106 cfu/g) which were subsequently reduced following the three months of storage. In the zinc fortified samples, the counts were higher compared to the other groups with no zinc addition. The addition of probiotics and zinc had no significant effect on the sensory properties of ice cream. As a final conclusion, the commercial production of zinc fortified ice cream is recommended.

The aim of this study was to investigate the effect of kumquat (Fortunella margarita) on the quality characteristics of ice cream. Kumquat paste (KP) was added to an ice cream mix at four concentrations, 0 (control), 5, 10 and 15% (w/w), for ice cream production. The increment of KP level caused an increase in acidity, vitamin C content, b* value and overrun value compared with the control ice cream. The apparent viscosity of samples decreased with the addition of KP at concentrations of 5 and 10% compared with the control. Results indicated that lyophilized water extract of KP (LKE) contained remarkable phenolic compounds. It was observed that LKE exhibited moderate in vitro antioxidant capacity. KP enhanced the color, flavor, vitamin C content and Mg and K contents of the ice cream. The addition of KP positively affected the sensory properties. KP may be used as a suitable source of natural color and flavor agent in ice cream production. KP enhanced the vitamin C content and Mg and K contents of ice cream and improved its sensory properties. © 2015 Society of Chemical Industry.

Pectin had been recovered from canning wastewater produced by chemical treatment of segment membrane during preparation of canned citrus in our previous research. The purpose of this study was to characterize the extracted pectin from canning wastewater, and to evaluate its application as a fat alternative to replace fat in ice cream. The monosaccharide composition and rheological properties of the pectin were determined. The influences of fat reduction and pectin addition on the physicochemical, rheological and sensory properties of low-fat ice cream were determined. The rheological results showed that pectin solutions were typical pseudoplastic fluids. The addition of pectin in ice cream can cause an increase in viscosity, overrun, and hardness, and a decrease in meltdown of the ice cream. When 0.72% pectin ( w / w ) is incorporated into ice cream, a prototype product of ice cream with 45% lower fat content compared to the control was made. Results indicated that their qualities such as appearance, flavor, and taste were not significantly different. The low-fat ice cream had higher smoothness scores and lower mouth-coating scores. Hence, pectin extracted from citrus canning wastewater can be potentially used as fat replacer in ice cream, which benefits both the environment and the food industry.

Solar ultraviolet exposure is the main cause of skin damage by initiation of reactive oxygen species (ROS) leading to skin collagen imperfection and eventually skin roughness. This can be reduced by proper revitalization of skin enhancing younger and healthier appearance. To evaluate the skin facial revitalization effect of a cream formulation containing the Moringa oleifera leaf extract on humans. Active cream containing 3% of the concentrated extract of moringa leaves was developed by entrapping in the inner aqueous phase of cream. Base contained no extract. Skin revitalizing parameters, i.e. surface, volume, texture parameters and surface evaluation of the living skin (SELS) were assessed comparatively after application of the base and active cream on human face using Visioscan(®) VC 98 for a period of 3 months. Surface values were increased by the base and decreased by the active cream. Effects produced for the base and active cream were significant and insignificant, respectively, as observed in the case of surface. Unlike the base, the active cream showed significant effects on skin volume, texture parameters (energy, variance and contrast) and SELS, SEr (skin roughness), SEsc (skin scaliness), SEsm (skin smoothness), and SEw (skin wrinkles) parameters. The results suggested that moringa cream enhances skin revitalization effect and supports anti-aging skin effects.

This study aimed to compare the effect of the stabilized novel topical botulinum neurotoxin type A (BoNTA) cream (CosmeTox) and a placebo cream on subjects, to compare clinician-reported outcomes, and to assess the safety and utility of the novel topical BoNTA cream for treating the entire upper face, chin, and neck areas. This study randomized 40 female subjects to receive either topical BoNTA (CosmeTox) cream (2 U/ml) or an identical placebo cream (without BoNTA) on the face, chin, and neck areas. The subjects were followed for 12 weeks. The main outcome measures were the Facial Line Outcomes questionnaire scores and results from the Self-Perception of Age instrument, which assesses age of appearance relative to actual age. The BoNTA topical cream (CosmeTox) treatment produced significant improvements in the Facial Lines Outcome scores, which were maintained throughout the study period and lasted more than 3 months. The BoNTA topical cream treatment also reduced the age of appearance for a majority of subjects. The placebo had no effect on any measure. No serious adverse events occurred during the entire study period. Topical treatment with the stabilized BoNTA cream (CosmeTox) to the entire upper facial lines resulted in significantly improved facial features and age appearance, as measured by the subjects and clinicians. The BoNTA cream (CosmeTox) resulted in a significantly younger, more satisfying, relaxed appearance.

Bacterial isolates, originating from 36 subclinically infected quarter milk samples, were labelled with 75Se and checked for cream-rising at various temperatures in a system analogous to the ABR test ("Abortus Bang Ringprobe"; the cream-rising test based on stained brucella organisms for detection of brucellosis). Diagnostic specificity and sensitivity were analyzed in experiments where labelled bacterial isolates were mixed with a number of quarter milk samples with known bacteriological status as well as samples from healthy control quarters. Creaming at 37 degrees C resulted in specific "recognization" as the bacterial isolates showed preferential flotation in the milk samples from which they had been isolated as well as is milk samples harbouring the same bacterial species. At lower creaming temperatures, the specificity was lost since all the isolates became concentrated in the cream phase irrespective of the milk sample. When comparing the specific recognization by cream of the respective bacteria, bacterial species vary: The prospects for developing diagnostic cream-rising tests for Streptococcus agalactiae, Staphylococcus aureus and Escherichia coli seems promising, but less so for coagulase-negative staphylococci, Streptococcus dysgalactiae, and Streptococcus uberis. The mechanism behind the cream-rising of labelled bacteria at 37 degrees C seems to lie in specific fat globule membrane-bound immunity of IgA type. Therefore the milk fat globules from chronically infected quarters function as absorbents for the respective isolates. Flotation of bacteria with cream indicates an in vivo mechanism enabling bacteria to invade the upper parts of milk ducts within the udder.(ABSTRACT TRUNCATED AT 250 WORDS)

In September 1994, the Minnesota Department of Health detected an increase in the number of reports of Salmonella enteritidis infections. After a case-control study implicated a nationally distributed brand of ice cream (Schwan's) in the outbreak, the product was recalled and further epidemiologic and microbiologic investigations were conducted. We defined an outbreak-associated case of S. enteritidis infection as one in which S. enteritidis was cultured from a person who became ill in September or October 1994. We established national surveillance and surveyed customers of the implicated manufacturer. The steps involved in the manufacture of ice cream associated with cases of S. enteritidis infection were compared with those of products not known to be associated with infection matched for the date of manufacture. Cultures for bacteria were obtained from ice cream samples, the ice cream plant, and tanker trailers that had transported the ice cream base (premix) to the plant. We estimate that S. enteritidis gastroenteritis developed in 224,000 persons in the United States after they ate Schwan's ice cream. The attack rate for consumers was 6.6 percent. Ice cream associated with infection contained a higher percentage of premix that had been transported by tanker that had carried nonpasteurized eggs immediately before (P = 0.02). S. enteritidis was isolated from 8 of 226 ice cream products (3 percent), but not from environmental samples obtained from the ice cream plant (n = 157) or tanker trailers (n = 204). This nationwide outbreak of salmonellosis was most likely the result of contamination of pasteurized ice cream premix during transport in tanker trailers that had previously carried nonpasteurized liquid eggs containing S. enteritidis. To prevent further outbreaks, food products not destined for repasteurization should be transported in dedicated containers.

Natural Oil-Based Emulsion Containing Allantoin Versus Aqueous Cream for Managing Radiation-Induced Skin Reactions in Patients With Cancer: A Phase 3, Double-Blind, Randomized, Controlled Trial

Purpose: To investigate the effects of a natural oil-based emulsion containing allantoin versus aqueous cream for preventing and managing radiation-induced skin reactions. Methods and Materials: A total of 174 patients were randomized and participated in the study. Patients received either cream 1 (the natural oil-based emulsion containing allantoin) or cream 2 (aqueous cream). Skin toxicity, pain, itching, and skin-related quality of life scores were collected for up to 4 weeks after radiation treatment. Results: Patients who received cream 1 had a significantly lower average level of Common Terminology Criteria for Adverse Events at week 3 (P<.05) but had statistically higher averagemore » levels of skin toxicity at weeks 7, 8, and 9 (all P<.001). Similar results were observed when skin toxicity was analyzed by grades. With regards to pain, patients in the cream 2 group had a significantly higher average level of worst pain (P<.05) and itching (P=.046) compared with the cream 1 group at week 3; however, these differences were not observed at other weeks. In addition, there was a strong trend for cream 2 to reduce the incidence of grade 2 or more skin toxicity in comparison with cream 1 (P=.056). Overall, more participants in the cream 1 group were required to use another topical treatment at weeks 8 (P=.049) and 9 (P=.01). Conclusion: The natural oil-based emulsion containing allantoin seems to have similar effects for managing skin toxicity compared with aqueous cream up to week 5; however, it becomes significantly less effective at later weeks into the radiation treatment and beyond treatment completion (week 6 and beyond). There were no major differences in pain, itching, and skin-related quality of life. In light of these results, clinicians and patients can base their decision on costs and preferences. Overall, aqueous cream seems to be a more preferred option.« less

The effect of additives on release and in vitro skin retention of flavonoids from emulsion and gel semisolid formulations.

To assess the effect of two different additives (propylene glycol (PG) and polyethylene glycol 400 (PEG 400)) on release and in vitro skin retention of quercetin and chrysin from semisolid bases (amphiphilic creams and acidic carbomer gels). For obtaining semisolid formulations, flavonoids were pre-dissolved in the liquid (PG or PEG 400) or directly suspended in the semisolid base. Three chrysin formulations ('cream 0', 'PG-cream' and 'PEG 400-cream') and five quercetin formulations ('cream 0', 'PG cream', 'PEG 400 cream', 'gel 0' and 'PG gel') were prepared. The release studies were carried out in Franz diffusion cells by means of a cellulose membrane. The porcine ear skin was used in in vitro skin retention studies. The dissolution was a prerequisite to increase the release rates of tested flavonoids from obtained semisolid formulations. The cumulative amount of chrysin released after 6 h from 'PEG 400 cream' containing partly dissolved form of that flavonoid was higher than that from 'cream 0' or 'PG cream' containing its suspended form. The formulations containing quercetin dissolved in PG ('PG cream', 'PG gel') or PEG 400 ('PEG 400 cream') exhibited higher release rates of that flavonoid than corresponding semisolid suspensions ('cream 0' or 'gel 0'). The effects of both liquid additives (PG and PEG 400) on the cumulative amount of quercetin released after 6 h were comparable. However, there was no correlation between the release rate and the skin retention. The amounts of the flavonoids found in the skin were strongly affected by the type of the used solvent. While PG increased the skin retention of both flavonoids, PEG 400 had no effect on chrysin skin retention and delayed quercetin skin absorption. The proper choice of the solvent added to the semisolid base is crucial for enhanced skin delivery of the tested flavonoids. PG is more efficient absorption promoter than PEG 400 of both chrysin and quercetin. © 2017 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

The investigation was aimed to determine prognostic factors related to postherpetic neuralgia (PHN), and treatment options for preventing PHN. The data showed 34 (17.0%) out of 188 patients with herpes zoster had severe pain after 4 weeks, and 22 (11.7%) after 8 weeks, compared with 109 (58.0%) at presentation. The age (>/=50 yr), surface area involved (>/=9%), and duration of severe pain (>/=4 weeks) might be the main factors that lead to PHN. On the other hand, gender, dermatomal distribution, accompanied systemic conditions, and interval between initial pain and initiation of treatment might not be implicated in PHN. The subjects were orally received antiviral (valacyclovir), tricyclic antidepressant (amitriptyline), and analgesic (ibuprofen) as the standard treatment in the group 1. In addition to the standard medication, lidocaine solution was sub- and/or perilesionally injected in the group 2, while lidocaine plus prilocaine cream was topically applied to the skin lesions in the group 3. The rates of PHN in the 3 treatment groups were not significantly different, suggesting adjuvant anesthetics may not be helpful to reduce the severity of pain. PMID:12378018

Anti-Pruritic Efficacy of Itch Relief Lotion and Cream in Patients With Atopic History: Comparison With Hydrocortisone Cream.

Objective: To evaluate the speed of onset and duration of relief of two ceramide-containing formulations with 1% pramoxine hydroxide (CeraVe® Itch Relief Lotion and Cream,Valeant Pharmaceuticals North America LLC, Irvine, CA) in patients with atopic history, including those with active flare and the comparative efficacy of CeraVe Itch Relief Cream to hydrocortisone 1% cream and night-time itch relief with continued use. Two double-blind, split-body, randomized studies in 66 male and female subjects, ages 11+ years, with history of atopic dermatitis (AD). Itch severity was assessed on a 10-point scale (where 0=none and 7-9=severe). Study one: single applications of ceramide-containing lotion or cream incorporating 1% pramoxine hydrochloride applied to opposite sides of the body. Study two (part 1): single application of ceramide-containing cream or hydrocortisone 1% cream. Study two (part 2): ceramide-containing pramoxine cream applied up to 4 times in a 24-hour period, over the course of 6 days. Itch relief assessed at baseline, 2, and 5 minutes, 1 (2 in study two), 4, and 8 hours post-application. Efficacy and aesthetic attributes were assessed at the same timepoints. Clinical evaluation of performance and mildness of the ceramide-containing 1% pramoxine hydrochloride cream at day 6 (study two, part 2). Study one: Relief of itching was rapid and long-lasting with significant reductions in severity after 2 minutes, and continued improvement over the 8 hour test period (P less than .001 versus baseline at all timepoints). Mean itch severity scores reduced progressively from 6 (moderate) at baseline to 1-2 (mild) after 8 hours, with all patients experiencing relief from itching. Rapid and long-lasting relief to dry, itchy, irritated skin was confirmed through patient self-assessment. Both lotion and cream formulations were non-greasy, absorbed quickly and easily, and were non-irritating. Study two: Ceramide-containing cream incorporating 1% pramoxine hydrochloride provided comparable improvement in itch relief (24.6% reduction in mean itch severity 2 minutes post-application, and 58.0% reduction 8 hours post-application) compared to hydrocortisone cream 1% (18.5% reduction and 59.7% reduction, respectively). Daily use of the ceramide-containing 1% pramoxine cream over 6-days provided all-night relief (87.5% agreement), and perception of skin looking and feeling healthier with each use (71.9% and 81.3% agreement, respectively). Results of study one and subsequent comparative study with hydrocortisone 1% cream are based on a single application. There were no placebo controls. Ceramide-containing lotion or cream containing 1% pramoxine provides both rapid and long-lasting relief of itching following a single application in atopic patients with or without active flare. Both formulations were well tolerated with aesthetic appeal. Comparable itch relief to hydrocortisone 1% cream was seen with the ceramide-containing cream over an 8-hour period following a single application. Further ceramide-containing 1% pramoxine hydrochloride cream was well tolerated with continued use over 6 days, delivering comfort and all-night relief for patients with atopic history suffering from reoccurrant itching.

Cost-Effectiveness of Ivermectin 1% Cream in Adults with Papulopustular Rosacea in the United States.

PubMed

2016-06-01

Papulopustular rosacea is a chronic skin disease involving central facial erythema in combination with papules and pustules. Papulopustular rosacea is treated with topical, systemic, or a combination of topical and systemic therapies. Currently approved topical therapies include azelaic acid gel/cream/foam twice daily (BID) and metronidazole cream/gel/lotion BID. Ivermectin 1% cream once daily (QD) is a new topical agent for the treatment of papulopustular rosacea that has been approved for the management of inflammatory lesions of rosacea and offers an alternative to current treatments. To evaluate the cost-effectiveness of ivermectin 1% cream QD compared with current topical treatments in order to understand the cost of adding ivermectin as a treatment option that would bring additional clinical benefit for adults with papulopustular rosacea in the United States. The cost-effectiveness of ivermectin 1% cream QD was compared with metronidazole 0.75% cream BID and azelaic acid 15% gel BID for adults in the United States with moderate-to-severe papulopustular rosacea using a Markov cohort state transition structure with 2 mutually exclusive health states (rosacea and no rosacea) and 5 phases. Patients could succeed or fail to respond to treatment and experience a relapse after treatment success. The model took a health care payer perspective (direct medical costs of topical and/or systemic therapy plus health care costs for physician and specialist visits) and used a 3-year time horizon. The model was run for a cohort of 1,000 patients. Costs (2014 U.S. dollars) and benefits (disease-free days and quality-adjusted life-years [QALYs]) were discounted at a rate of 3% per annum. Cost-effectiveness was determined by the incremental cost-effectiveness ratio (ICER) and measured in terms of incremental cost per QALY gained (estimated from health state utilities for patients with and without rosacea). Univariate and probabilistic sensitivity analyses (PSA) were conducted to assess the robustness of model outcomes. Compared with metronidazole 0.75% cream BID, ivermectin 1% cream QD was associated with higher costs but provided greater clinical benefit, with an ICER of $13,211 per QALY gained. For a cohort of 1,000 patients, ivermectin 1% cream QD provided an additional 72,922 disease-free days (200 years) over a 3-year period compared with metronidazole 0.75% cream BID, leading to a lower cost per disease-free day for ivermectin 1% cream QD ($4.54) compared with metronidazole 0.75% cream BID ($4.85). Ivermectin 1% cream QD was associated with lower total costs and greater clinical benefit compared with azelaic acid 15% gel BID at year 3 and dominated this treatment. After 3 years, ivermectin 1% cream QD was associated with the lowest health care costs ($62,767 compared with $73,284 for metronidazole 0.75% cream BID and $77,208 for azelaic acid 15% gel BID), reflecting a 15% reduction in physician visit costs, when compared with metronidazole 0.75% cream BID, and almost a 20% reduction, when compared with azelaic acid 15% gel BID. The univariate sensitivity analyses indicated that the results are sensitive to the time horizon selected: the longer the time horizon, the more beneficial the results for ivermectin 1% cream QD relative to the comparators, although even at 1 year, ivermectin 1% cream QD dominated azelaic acid 15% gel BID. The PSA suggested that ivermectin 1% cream QD was the most likely treatment to be cost-effective at a willingness-to-pay threshold of $15,000 and above. Ivermectin 1% cream QD had favorable incremental cost-effectiveness when compared with metronidazole 0.75% cream BID and dominated azelaic acid 15% gel BID in the treatment of papulopustular rosacea in the United States. Therefore, ivermectin 1% cream QD may be a good first-line treatment for papulopustular rosacea, providing additional clinical benefit at no or low additional cost. This study was sponsored by Galderma Laboratories. The sponsor was involved in the design of the model structure but not in the collection of the data used to populate the m

What device would be best for early infant male circumcision in east and southern Africa? Provider experiences and opinions with three different devices in Kenya.

Voluntary medical male circumcision (VMMC) reduces risk of HIV acquisition in heterosexual men by approximately 60%. As some countries approach targets for proportions of adolescents and adults circumcised, some are considering early infant male circumcision (EIMC) as a means to achieve sustainability of VMMC for long term reduction of HIV incidence. Evaluations of specialized devices for EIMC are important to provide programs with information required to make informed decisions about how to design safe, effective EIMC programs. We provide assessments by 11 providers with experience in Kenya employing all three of the devices most likely to be considered by various EIMC programs in east and Southern Africa. There was no one device that was seen to be clearly superior to the others. Each had its own advantages and disadvantages. Provider preferences were situation-specific. Most preferred the Mogen Clamp if they themselves were performing the procedure. However, most were concerned that not everyone will have the skills necessary for optimal safety. If someone else were circumcising their son, most would opt for the AccuCirc because of the risk of severing the glans when using the Mogen. A minority preferred the PrePex, but only if the baby received local anesthesia, not EMLA cream (a eutectic mixture of lidocaine 2.5% and prilocaine 2.5%), as presently prescribed by the manufacturer. In the context of a national EIMC program, all participants agreed that AccuCirc would be the device they would recommend due to protection of the glans from laceration and to the provision of a pre-assembled sterile kit that overcomes the need for additional supplies or autoclaving. All agreed that scaling up EIMC, integrating it with existing maternal child health services, will face significant challenges, not least of which is persuading already over-burdened providers to take on additional workload. These results will be useful to programmers considering introduction of EIMC services in sub-Saharan African settings.

The objective of present work was to develop novel sunscreen creams containing polymeric nanoparticles (NPs) of morin. Polymeric NPs containing morin were prepared and optimized. The creams containing morin NPs were also prepared and evaluated. Optimized NPs exhibited particle size of 90.6 nm and zeta potential of −31 mV. The entrapment efficiency of morin, within the polymeric NPs, was found to be low (12.27%). Fourier transformed infrared spectroscopy and differential scanning calorimetry studies revealed no interaction between morin and excipients. Transmission electron microscopy and atomic force microscopy revealed that the NPs were spherical in shape with approximately 100 nm diameter. Optimized NPs showed excellent in vitro free radical scavenging activity. Skin permeation and deposition of morin from its NPs was higher than its plain form. Different sunscreen creams (SC1–SC8) were formulated by incorporating morin NPs along with nano zinc oxide and nano titanium dioxide. SC5 and SC8 creams showed excellent sun protection factor values (≈40). In vitro and in vivo skin permeation studies of sunscreen creams containing morin NPs indicated excellent deposition of morin within the skin. Morin NPs and optimized cream formulations (SC5 and SC8) did not exhibit cytotoxicity in Vero and HaCaT cells. Optimized sunscreen creams showed excellent dermal safety. SC5 and SC8 creams demonstrated exceptional in vivo antioxidant effect (estimation of catalase, superoxide dismutase, and glutathione) in UV radiation-exposed rats. The optimized sunscreen creams confirmed outstanding UV radiation protection as well as antioxidant properties. PMID:26508854

The Effects of Fat Structures and Ice Cream Mix Viscosity on Physical and Sensory Properties of Ice Cream.

2017-08-01

The purpose of this work was to investigate iciness perception and other sensory textural attributes of ice cream due to ice and fat structures and mix viscosity. Two studies were carried out varying processing conditions and mix formulation. In the 1st study, ice creams were collected at -3, -5, and -7.5 °C draw temperatures. These ice creams contained 0%, 0.1%, or 0.2% emulsifier, an 80:20 blend of mono- and diglycerides: polysorbate 80. In the 2nd study, ice creams were collected at -3 °C draw temperature and contained 0%, 0.2%, or 0.4% stabilizer, a blend of guar gum, locust bean gum, and carrageenan. Multiple linear regressions were used to determine relationships between ice crystal size, destabilized fat, and sensory iciness. In the ice and fat structure study, an inverse correlation was found between fat destabilization and sensory iciness. Ice creams with no difference in ice crystal size were perceived to be less icy with increasing amounts of destabilized fat. Destabilized fat correlated inversely with drip-through rate and sensory greasiness. In the ice cream mix viscosity study, an inverse correlation was found between mix viscosity and sensory iciness. Ice creams with no difference in ice crystal size were perceived to be less icy when formulated with higher mix viscosity. A positive correlation was found between mix viscosity and sensory greasiness. These results indicate that fat structures and mix viscosity have significant effects on ice cream microstructure and sensory texture including the reduction of iciness perception. © 2017 Institute of Food Technologists®.

The mixture of olive oil and lime cream has been traditionally used to treat external burns in the region of Hatay/Antakya and middle Anatolia. Olive oil and lime cream have been employed by many physicians to treat many ailments in the past. A limited number of studies have shown the antibacterial effect of olive oil and that it does not have any toxic effect on the skin. But we did not find any reported studies on the mixture of olive oil and lime cream. The aim of this paper is to investigate the cytotoxic and antibacterial activity of olive oil and lime cream individually or/and in combination in vitro conditions, by using disk-diffusion method and in cell culture. The main purpose in using this mixture is usually to clear burns without a trace. Agar overlay, MTT (Cytotoxicity assay) and antibacterial susceptibility tests were used to investigate the cytotoxic and antibacterial activity of olive oil and lime cream. We found that lime cream has an antibacterial activity but also cytotoxic on the fibroblasts. On the other hand olive oil has limited or no antibacterial effect and it has little or no cytotoxic on the fibroblasts. When we combined lime cream and olive oil, olive oil reduced its cytotoxic impact. These results suggest that mixture of olive oil and lime cream is not cytotoxic and has antimicrobial activity.

The objective of this study was to determine how varying concentrations of the stabilizer, locust bean gum (LBG), and different levels of the emulsifier, mono- and diglycerides (MDGs), influenced fat aggregation and melting characteristics of ice cream. Ice creams were made containing MDGs and LBG singly and in combination at concentrations ranging between 0.0% to 0.14% and 0.0% to 0.23%, respectively. Particle size analysis, conducted on both the mixes and ice cream, and melting rate testing on the ice cream were used to determine fat aggregation. No significant differences (P < 0.05) were found between particle size values for experimental ice cream mixes. However, higher concentrations of both LBG and MDG in the ice creams resulted in values that were larger than the control. This study also found an increase in the particle size values when MDG levels were held constant and LBG amounts were increased in the ice cream. Ice creams with higher concentrations of MDG and LBG together had the greatest difference in the rate of melting than the control. The melting rate decreased with increasing LBG concentrations at constant MDG levels. These results illustrated that fat aggregation may not only be affected by emulsifiers, but that stabilizers may play a role in contributing to the destabilization of fat globules. © 2013 Institute of Food Technologists®

Amla (Indian gooseberry) and its processed products are rich source of vitamin C, phenols, dietary fibre and antioxidants. In contrast, ice cream is a poor source of these phytochemicals and antioxidants; therefore, the present investigation was undertaken to enhance the functional properties and nutritional quality of ice cream with the incorporation of processed amla. Ice cream was prepared using amla shreds, pulp, preserve and candy at 5 to 20 % and powder at 0.5 to 2.0 % levels in ice cream mix prior to freezing. Inclusion of amla products at augmented levels resulted in significant changes in physico-chemical properties and phytochemical content of ice cream. The total solids decreased on addition of shreds and pulp and increased with preserve, candy and powder in ice cream at increasing levels. The functional constituents i.e. fibre, total phenols, tannins, ascorbic acid and antioxidant activity increased with greater level of inclusion. Incorporation of processed amla raised the melting resistance of ice cream and decreased the overrun. The samples with 5 % shreds and pulp, 10 % preserve and candy and 0.5 % powder were found to have highest overall acceptability scores. Inclusion of amla in all the forms i.e. shreds, pulp, preserve, candy and powder enhanced the functional properties and nutritional value of ice cream.

Laser-induced breakdown spectroscopy (LIBS) was used to evaluate the effect of barrier creams (skin protective creams) on human skin. A Nd: YAG laser at 1,064 nm was used with a pulse energy of 100 mJ. A method was developed to measure the effectiveness of barrier creams against zinc ion absorption from aqueous zinc chloride solution and oil paste zinc oxide, which represent model hydrophilic and lipophilic metal compounds, respectively. Zinc was chosen since it posed no risk to human skin. 3 representative commercial barrier creams advertised as being effective against lipophilic and hydrophilic substances were evaluated by measuring zinc absorbed through the stratum corneum. 4 consecutive skin surface biopsies (SSB) were taken from biceps of the forearms of 6 volunteers at time periods of 0.5 h and 3 h after application of the protective cream. Results were compared with control skin where no barrier cream was used. The zinc atomic emission line at 213.9 nm was selected. Gate delay and gate width time was optimized to obtain the best signal-to-noise ratio (SNR) and precision. This method provided a facile and rapid screening of the effectiveness of skin barrier creams against zinc ion penetration. The barrier creams were shown to provide appreciable protection against the penetration of both ZnCl2 and ZnO into the skin.

A randomized and placebo-controlled study to compare the skin-lightening efficacy and safety of lignin peroxidase cream vs. 2% hydroquinone cream.

  Historically, the most effective treatments for skin lightening have contained hydroquinone. However, there is a need for an effective alternative.   The purpose of this study was to evaluate the skin-lightening efficacy and safety of lignin peroxidase (LIP) creams using a regimen of both day and night products compared with twice-daily application of 2% hydroquinone cream and placebo in Asian women.   This was a randomized, double-blind, placebo-controlled, split-face, single-center study of 51 patients. Patients were randomized to receive day and night LIP cream on one randomly selected side of their face and either 2% hydroquinone cream or placebo on the other.   A statistically significant change from baseline in the melanin index was observed in LIP-treated skin, with a mean reduction of 7.6% (P < 0.001) on Day 31. Conversely, hydroquinone and placebo did not provide a statistically significant lightening effect when instrumentally measured. Dermatologist scoring demonstrated a significant improvement in overall fairness as early as 8 days after treatment initiation in the LIP-treated group, which was not observed in the other groups. Overall, patients preferred the LIP creams.   The application of day/night LIP cream provided a significantly more rapid and observable skin-lightening effect than hydroquinone 2% cream or placebo. © 2011 Wiley Periodicals, Inc.

Seborrheic dermatitis (SD) is an inflammatory skin disorder affecting the scalp, face, and trunk, however, there are controversies surrounding its treatment. The aim of the study is to compare the efficacy of sertaconazole 2% cream with hydrocortisone 1% cream in the treatment of seborrheic dermatitis. In total, 138 patients suffering from seborrheic dermatitis were studied. Sixty-nine patients received local sertoconazole 2% cream and they were recommended to use the cream twice a day and for 4 weeks. To create a control group, 69 patients received hydrocortisone 1% cream twice a day for four weeks. At the time of referral, and at 2 and 4 weeks after their first visit, the patients were examined by a dermatologist to check the improvement of clinical symptoms. The mean age of patients was 36.45 +/- 13.23. The highest level of satisfaction (85.1%) was observed 28 days after sertaconazole consumption: 76.9% was recorded for the hydrocortisone group. No relapse of the disease one month after stopping treatment was observed in either the sertaconazole 2% group or the hydrocortisone 1% group. Sertaconazole 2% cream may be an excellent alternative therapeutic modality for treating seborrheic dermatitis.

Allium ampeloprasum subsp iranicum (Leek) has been traditionally used in antihemorrhoidal topical herbal formulations. This study aimed to evaluate its safety and efficacy in a pilot randomized controlled clinical trial. Twenty patients with symptomatic hemorrhoids were randomly allocated to receive the topical leek extract cream or standard antihemorrhoid cream for 3 weeks. The patients were evaluated before and after the intervention in terms of pain, defecation discomfort, bleeding severity, anal itching severity, and reported adverse events. A significant decrease was observed in the grade of bleeding severity and defecation discomfort in both the leek and antihemorrhoid cream groups after the intervention, while no significant change was observed in pain scores. There was no significant difference between the leek and antihemorrhoid cream groups with regard to mean changes in outcome measures. This pilot study showed that the topical use of leek cream can be as effective as a standard antihemorrhoid cream. © The Author(s) 2015.

The effect of gum tragacanth on the rheological properties of salep based ice cream mix.

Kurt, Abdullah; Cengiz, Alime; Kahyaoglu, Talip

2016-06-05

The influence of concentration (0-0.5%, w/w) of gum tragacanth (GT) on thixotropy, dynamic, and creep-recovery rheological properties of ice cream mixes prepared with milk or water based were investigated. These properties were used to evaluate the viscoelastic behavior and internal structure of ice cream network. The textural properties of ice cream were also evaluated. Thixotropy values of samples were reduced by increasing GT concentration. The dynamic and creep-recovery analyses exhibited that GT addition increased both ice cream elastic and viscous behaviors. The increasing of Burger's model parameters with GT concentration indicated higher resistance network to the stress and more elastic behavior of samples. The applying of Cox-Merz rule is possible by using shift factor (α). GT also led to an increase in Young's modulus and the stickiness of ice creams. The obtained results highlighted the possible application of GT as a valuable member to promote structural properties of ice cream. Copyright © 2016 Elsevier Ltd. All rights reserved.

Contamination of chlorhexidine cream used to prevent ascending urinary tract infections.

PubMed Central

Salveson, A.; Bergan, T.

1981-01-01

Chlorhexidine-containing cream is often used as an antimicrobial barrier to ascending urinary tract infection in patients with indwelling urethral catheters. The cream is dispensed in small tubes for personal use but repeated use of a tube still entails a potential infection hazard. The extent of cream contamination was analysed by emulsifying it in 1% peptone broth with 1% Tween-80 added as a wetting agent, and culturing quantitatively for bacteria and fungi by membrane filtration. Twenty-three per cent of cream samples and 35% of swabs taken from outside the tube beneath the screw cap demonstrated microbial contamination. Isolates included potential pathogens such as enterococci, staphylococci, Proteus mirabilis, Pseudomonas aeruginosa, opportunists like Moraxella spp. and diphtheroids, and contaminants such as Bacillus spp., micrococci, and a mould of the genus Cladosporium. Contamination of cream with a particular bacterial strain was found to precede urinary tract infection with the same microbe. We recommend that chlorhexidine cream for this use be dispensed in single dose units to ensure sterility. PMID:7240733

Tactile perception of skin and skin cream by friction induced vibrations.

PubMed

Ding, Shuyang; Bhushan, Bharat

2016-11-01

Skin cream smooths, softens, and moistens skin by altering surface roughness and tribological properties of skin. Sliding generates vibrations that activate mechanoreceptors located in skin. The brain interprets tactile information to identify skin feel. Understanding the tactile sensing mechanisms of skin with and without cream treatment is important to numerous applications including cosmetics, textiles, and robotics sensors. In this study, frequency spectra of friction force and friction induced vibration signals were carried out to investigate tactile perception by an artificial finger sliding on skin. The influence of normal load, velocity, and cream treatment time were studied. Coherence between friction force and vibration signals were found. The amplitude of vibration decreased after cream treatment, leading to smoother perception. Increasing normal load or velocity between contacting surfaces generated a smoother perception with cream treatment, but rougher perception without treatment. As cream treatment time increases, skin becomes smoother. The related mechanisms are discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

Optimization of fat-reduced ice cream formulation employing inulin as fat replacer via response surface methodology.

Pintor, Aurora; Severiano-Pérez, Patricia; Totosaus, Alfonso

2014-10-01

The use of new ingredients like inulin for fat replacement is of wide application in the food industry. The aim of the present work was to reduce the fat content on ice cream formulations. It was possible to reduce up to 25% of butyric and vegetable fats with 3% of inulin, with good textural and sensory characteristics of the final product. The substitution of fat with inulin increased the ice cream mix viscosity, improved air incorporation, and produced ice cream with soft and homogeneous textures. Color characteristics were not affected by the replacement. Hedonic sensory analysis showed that optimized fat-reduced inulin ice cream was not perceived different to commercial vanilla ice cream. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

When ice cream was poisonous: adulteration, ptomaines, and bacteriology in the United States, 1850-1910.

Geist, Edward

2012-01-01

With the increasing popularity of ice cream in the nineteenth century, the incidence of foodborne illness attributed to this dessert exploded. Struggling to understand the causes of the mysterious and sometimes lethal ailment called "ice cream poisoning," Victorian doctors and scientists advanced theories including toxic vanilla, galvanism in ice cream freezers, and extreme indigestion. In the late 1880s Victor C. Vaughan's argument that ice cream poisoning could be attributed to the ptomaine "tyrotoxicon" received widespread acceptance. To date historians have neglected the role played by the ptomaine theory of food poisoning in shaping the evolution of both scientific thinking and public health in the late nineteenth century. The case of ice cream poisoning illustrates the emergence, impact, and decline of the ptomaine idea.

Explaining tolerance for bitterness in chocolate ice cream using solid chocolate preferences.

Chocolate ice cream is commonly formulated with higher sugar levels than nonchocolate flavors to compensate for the inherent bitterness of cocoa. Bitterness, however, is an integral part of the complex flavor of chocolate. In light of the global obesity epidemic, many consumers and health professionals are concerned about the levels of added sugars in foods. Once a strategy for balancing undesirable bitterness and health concerns regarding added sugars has been developed, the task becomes determining whether that product will be acceptable to the consumer. Thus, the purpose of this research was to manipulate the bitterness of chocolate ice cream to examine how this influences consumer preferences. The main goal of this study was to estimate group rejection thresholds for bitterness in chocolate ice cream, and to see if solid chocolate preferences (dark vs. milk) generalized to ice cream. A food-safe bitter ingredient, sucrose octaacetate, was added to chocolate ice cream to alter bitterness without disturbing other the sensory qualities of the ice cream samples, including texture. Untrained chocolate ice cream consumers participated in a large-scale sensory test by indicating their preferences for blinded pairs of unspiked and spiked samples, where the spiked sample had increasing levels of the added bitterant. As anticipated, the group containing individuals who prefer milk chocolate had a much lower tolerance for bitterness in their chocolate ice cream compared with the group of individuals who prefer dark chocolate; indeed, the dark chocolate group tolerated almost twice as much added bitterant in the ice cream before indicating a significant preference for the unspiked (control) ice cream. This work demonstrates the successful application of the rejection threshold method to a complex dairy food. Estimating rejection thresholds could prove to be an effective tool for determining acceptable formulations or quality limits when considering attributes that become objectionable at high intensities.

Topical tretinoin is considered the gold standard to treat photoaged skin, but it is associated with side effects and only available upon prescription. To compare the efficacy, tolerance, and perception of a fixed proprietary combination (Retinol 0.2%/LR2412 2%) vs. tretinoin 0.025% cream in women with photoaged skin. In this randomized, parallel, double-blind, controlled clinical study, women applied to the entire face for 3 months in the morning a SPF 50 sunscreen and in the evening either the association of Retinol 0.2%/LR2412 2% or tretinoin 0.025%. Clinical and instrumental parameters were assessed at days 0, 28, 56, and 84. Subject perception of the efficacy, tolerance and cosmeticity of the tested products were assessed at days 28, 56, and 84. A total of 120 women (60 to Retinol 0.2%/LR2412 2% cream and 60 to tretinoin 0.025% cream) were included in the study. Both products improved considerably wrinkles, mottled pigmentation, pores, and global photodamage. No statistically significant differences were noted between Retinol 0.2%/LR2412 2% cream and tretinoin 0.025% cream. Adverse effects were mostly graded mild. Overall, Retinol 0.2%/LR2412 2% cream was better tolerated than tretinoin 0.025% cream. At all visits, subject perception of the association of Retinol 0.2%/LR2412 2% was either comparable to or better than tretinoin 0.025% cream. The treatment outcome of Retinol 0.2%/LR2412 2% cream does not differ from the one of tretinoin 0.025% cream. Clinical results were not statistically different. Furthermore, Retinol 0.2%/LR2412 2% cream is better tolerated and better perceived by women used to rejuvenation procedures. © 2015 The Authors Journal of Cosmetic Dermatology Published by Wiley Periodicals, Inc.

Crystallization mechanisms in cream during ripening and initial butter churning.

PubMed

Buldo, Patrizia; Kirkensgaard, Jacob J K; Wiking, Lars

2013-01-01

The temperature treatment of cream is the time-consuming step in butter production. A better understanding of the mechanisms leading to partial coalescence, such as fat crystallization during ripening and churning of the cream, will contribute to optimization of the production process. In this study, ripening and churning of cream were performed in a rheometer cell and the mechanisms of cream crystallization during churning of the cream, including the effect of ripening time, were investigated to understand how churning time and partial coalescence are affected. Crystallization mechanisms were studied as function of time by differential scanning calorimetry, nuclear magnetic resonance and by X-ray scattering. Microstructure formation was investigated by small deformation rheology and static light scattering. The study demonstrated that viscosity measurements can be used to detect phase inversion of the emulsion during churning of the cream in a rheometer cell. Longer ripening time (e.g., 5h vs. 0 h) resulted in larger butter grains (91 vs. 52 µm), higher viscosity (5.3 vs. 1.3 Pa · s), and solid fat content (41 vs. 13%). Both ripening and churning time had an effect on the thermal behavior of the cream. Despite the increase in solid fat content, no further changes in crystal polymorphism and in melting behavior were observed after 1h of ripening and after churning. The churning time significantly decreased after 0.5h of ripening, from 22.9 min for the cream where no ripening was applied to 16.23 min. Therefore, the crystallization state that promotes partial coalescence (i.e., aggregation of butter grains) is obtained within the first hour of cream ripening at 10 °C. The present study adds knowledge on the fundamental processes of crystallization and polymorphism of milk fat occurring during ripening and churning of cream. In addition, the dairy industry will benefit from these insights on the optimization of butter manufacturing. Copyright © 2013 American Dairy Science Association. Published by Elsevier Inc.

2015-05-01

The aim of this study was to compare vasoconstrictor activity and, by inference, the clinical anti-inflammatory effectiveness of hydrocortisone in two different formulations: 1% dissolved hydrocortisone cream and 1% dispersed hydrocortisone cream. Moisturising capacity and safety were also determined. Both topical preparations were applied without occlusion on forearms twice daily for 5 days. An assessment of vasoconstriction was performed in a double-blinded manner pretreatment and then thrice daily for 6 days and once 7 days post-application, using an objective rating scale. For the dissolved preparation only, moisturising capacity was determined by measurement of transepidermal water loss (TEWL) at 0, 2, 4, 6 and 24 h, and also by the measurement of water content at 0 and 24 h. Safety was assessed by repeat insult patch tests (RIPT). In all, 10 volunteers completed the vasoconstrictor and moisturising studies, while 52 completed the RIPT. For 1% dissolved hydrocortisone cream and 1% dispersed hydrocortisone cream, respectively, areas under the blanching curves were 1240 and 295; total scores were 129.0 and 31.5; summed % total possible scores were 161.3 and 39.4; Tm/10 mean values were 3.47 and 1.64. The 1% dissolved hydrocortisone cream was found to be statistically more potent than the 1% dispersed hydrocortisone cream. Furthermore, the 1% dissolved hydrocortisone cream was found to be moisturising compared to no treatment. No adverse events were observed. A cream containing 1% dissolved hydrocortisone exhibits greater vasoconstrictor activity than a cream containing 1% dispersed hydrocortisone. © 2013 The Authors.

The management of sensitive skin, which affects over 60% of the general population, has been a long-standing challenge for both patients and clinicians. Because defective epidermal permeability barrier is one of the clinical features of sensitive skin, barrier-enhancing products could be an optimal regimen for sensitive skin. In the present study, we evaluated the efficacy and safety of two barrier-enhancing products, i.e., Atopalm (®) Multi-Lamellar Emulsion (MLE) Cream and Physiogel (®) Intensive Cream for sensitive skin. 60 patients with sensitive skin, aged 22-40 years old, were randomly assigned to one group treated with Atopalm MLE Cream, and another group treated with Physiogel Intensive Cream twice daily for 4 weeks. Lactic acid stinging test scores (LASTS), stratum hydration (SC) and transepidermal water loss (TEWL) were assessed before, 2 and 4 weeks after the treatment. Atopalm MLE Cream significantly lowered TEWL after 2 and 4 weeks of treatment (p < 0.01). In contrast, Physiogel Intensive Cream significantly increased TEWL after 2 weeks of treatment (p < 0.05) while TEWL significantly decreased after 4-week treatments. Moreover, both Atopalm MLE Cream and Physiogel Intensive Cream significantly increased SC hydration, and improved LASTS after 4 weeks of treatment. Both barrier-enhancing products are effective and safe for improving epidermal functions, including permeability barrier, SC hydration and LASTS, in sensitive skin. These products could be a valuable alternative for management of sensitive skin. Veterans Affairs Medical Center, San Francisco, California, USA, and NeoPharm Co., Ltd., Daejeon, Korea.

Optimal bone mass in early adulthood is achieved through appropriate diet and lifestyle, thereby protecting against osteoporosis and risk of bone fracture in later life. Calcium and vitamin D are essential to build adequate bones, but calcium intakes of many population groups do not meet dietary reference values. In addition, changes in dietary patterns are exacerbating the problem, thereby emphasizing the important role of calcium-rich food products. We have designed a calcium-fortified ice cream formulation that is lower in fat than regular ice cream and could provide a useful source of additional dietary calcium. Calcium absorption from two different ice cream formulations was determined in young adults and compared with milk. Sixteen healthy volunteers (25 to 45 years of age), recruited from the general public of The Netherlands, participated in a randomized, reference-controlled, double-blind cross-over study in which two test products and milk were consumed with a light standard breakfast on three separate occasions: a standard portion of ice cream (60 g) fortified with milk minerals and containing a low level (3%) of butter fat, ice cream (60 g) fortified with milk minerals and containing a typical level (9%) of coconut oil, and reduced-fat milk (1.7% milk fat) (200 mL). Calcium absorption was measured by the dual-label stable isotope technique. Effects on calcium absorption were evaluated by analysis of variance. Fractional absorption of calcium from the 3% butterfat ice cream, 9% coconut oil ice cream, and milk was 26%+/-8%, 28%+/-5%, and 31%+/-9%, respectively, and did not differ significantly (P=0.159). Results indicate that calcium bioavailability in the two calcium-fortified ice cream formulations used in this study is as high as milk, indicating that ice cream may be a good vehicle for delivery of calcium.

A study was performed to apply a probiotic strain into fermented ice cream mix with suitable fruit bases to develop a value-added product with a substantial level of viable organisms for a sufficient shelf life. Pure direct vat strain culture of Lactobacillus acidophilus (LA 5) in freeze-dried form was inoculated into a mixture of ice cream, frozen, and the number of viable organisms during frozen storage for a period of time was enumerated, using turbidity measurements with a spectrophotometer. An ice cream sample prepared without the probiotic culture was compared with the test sample for quality, by testing the basic quality parameters for ice cream. Results show a reduction in the over run of the probiotic ice cream compared to the nonprobiotic ice cream. Significantly high level (P < 0.05) of total solids (42%), proteins (16.5%), and titratable acidity (2.2%) was observed in the test sample compared to the nonprobiotic ice cream. Significantly low pH level in the probiotic sample may be due to the lactic acid produced by the probiotic culture. No significant difference (P > 0.05) in the fat content in the two types of ice cream was observed. A significantly low level (P < 0.05) of melting in the probiotic one may have resulted from less over run, than the nonprobiotic sample. Rapid reduction in the viable cells during frozen storage occurred at −18°C and gradual adaptation occurred over the first 4 weeks. At the 10th week, 1.0 × 107 numbers of viable organisms were present in 1 g of the probiotic ice cream. Results show the presence of a sufficient number of viable organisms in the product for the 10-week period, which would be beneficial to consumers. PMID:24804052

It was hypothesized that frozen yogurt and ice cream would be less healthy than yogurt. We examined daily energy and nutrient intake from yogurt, frozen yogurt, and ice cream among US adults. In-person 24-hour dietary recall data (n=6453) came from the 1999-2014 National Health and Nutrition Examination Survey. Regression analyses were performed to examine the differences in energy/nutrient intake from frozen yogurt and ice cream (with/without toppings) in comparison to yogurt. Approximately 5.3%, 0.9%, and 14.3% of US adults consumed yogurt, frozen yogurt, and ice cream on any given day, respectively. Among frozen yogurt and ice cream consumers, 29.7% and 14.8% added toppings to their consumption, respectively. Compared with yogurt, frozen yogurt consumption with and without toppings was associated with increased daily energy intake by 214.6 and 97.9kj, respectively; whereas ice cream consumption with and without toppings was associated with increased daily energy intake by 427.2 and 343.5kj, respectively. Compared with yogurt, frozen yogurt consumption was associated with a decreased intake of most vitamins/minerals under examination, but increased intake of sugar, total/saturated fat, cholesterol, fiber, and iron. Adding toppings to frozen yogurt further increased total and saturated fat intake. Compared with yogurt, ice cream consumption was associated with a decreased intake of multiple micronutrients, but increased intake of sugar, total/saturated fat, cholesterol, fiber, vitamins A and E, and iron. Adding toppings to ice cream further increased sugar intake. In conclusion, frozen yogurt and ice cream were less healthy than yogurt, and adding toppings made them even less desirable.

To evaluate the safety and efficacy of civamide cream 0.075% for the treatment of osteoarthritis (OA) of the knee. We conducted a 12-week, multicenter, randomized, double-blind study with a 52-week open-label extension. Patients with OA of the knee received either civamide cream 0.075% or a lower dose of civamide cream, 0.01%, as the control. The 3 co-primary endpoints in the double-blind study were the time-weighted average (TWA) of change from baseline to Day 84 in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale, the WOMAC physical function subscale, and the Subject Global Evaluation (SGE). In the 52-week open-label extension study, the Osteoarthritis Pain Score and SGE were assessed. A total of 695 patients were randomized to receive civamide cream 0.075% (n = 351) or civamide cream 0.01% (control; n = 344) in the double-blind study. Significance in favor of civamide cream 0.075% was achieved for the TWA for all 3 co-primary efficacy variables: WOMAC pain (p = 0.009), WOMAC physical function (p < 0.001), and SGE (p = 0.008); and at Day 84 for these 3 variables (p = 0.013, p < 0.001, and p = 0.049, respectively). These analyses accounted for significant baseline-by-treatment interactions. In the 52-week open-label extension, efficacy was maintained. Civamide cream 0.075% was well tolerated throughout the studies. These studies demonstrate the efficacy of civamide cream for up to 1 year of continuous use. Civamide cream, with its lack of systemic absorption, does not have the potential for serious systemic toxicity, in contrast to several other OA treatments.

Melasma is a common acquired cause of facial hyperpigmentation seen predominantly among females with significant psychological and social impact. It is often recalcitrant to treatment. Several topical hypopigmenting agents have been used to combat melasma. Hydroquinone and Kojic Acid are well established monotherapeutic agents for treating melasma. This study focuses mainly on the efficacy of once daily application of 4% Hydroquinone and 0.75% Kojic Acid cream (containing 0.75% Kojic acid and 2.5% vitamin C) so as to determine an effective modality of treatment for facial melasma. A total number of 60 patients with facial melasma attending the Out-patient department of Dermatology, Venerology and Leprosy, Fr. Muller Medical College Hospital, Mangalore from Oct 2008-April 2010 were studied. Patients were allocated alternately to group A and group B. Group A patients received 4% Hydroquinone cream and group B patient received a Kojic Acid cream (which contained 0.75% Kojic acid and 2.5% vitamin C) and were advised to apply topically once daily at night. Patients were followed up on 4(th), 8(th) and 12(th) week. At each visit side effects were noted and clinical response to treatment was calculated using the MASI score. Chi square test, student 't' test. At the 4(th) week post treatment evaluation, facial hyperpigmentation responded early to 4% Hydroquinone cream than to 0.75% Kojic Acid cream. At the end of 12 week treatment period, 4% Hydroquinone cream had an overall superiority to 0.75% Kojic Acid cream as a topical hypopigmenting agent. The results of the study show that 4% Hydroquinone cream is a better topical hypopigmenting agent with rapid rate of clinical improvement when compared to 0.75% Kojic Acid cream.

Melastoma malabathricum is a traditional herb that is used to treat wound on skin. It has also been proven to have antiviral activity against Herpes Simplex virus type 1 (HSV-1). In this study, M. malabathricum cream formulation was developed by incorporating M. malabathricum aqueous extract into cream base. The safety and biocompatibility of the formulated cream was investigated by topically applying the cream onto the back of ICR mice skin. Treatment with M. malabathricum was found to accelerate wound contraction with less scar formation. The effect of M. malabathricum has prompted a possibility that M. malabathricum might contribute in enhancing the healing process of cutaneous lesion caused by HSV-1. The formulated cream did not cause any skin irritation or adverse effect to ICR mice when topically applied within seven days of exposure.

Luliconazole is a novel topical antifungal imidazole with broad-spectrum and potent antifungal activity. The drug is under clinical development in the United States for management of dermatophytosis with a short-term treatment regimen. The present study was undertaken to investigate the clinical benefit of short-term therapy with luliconazole cream in guinea pig models of tinea corporis and tinea pedis induced with Trichophyton mentagrophytes. The dose-dependent therapeutic efficacy of topical luliconazole cream (0.02 to 1%), measured by macroscopic improvement of skin lesions and by fungal eradication as determined by a culture assay, was demonstrated using a tinea corporis model. The improvement in skin lesions seen with luliconazole cream was observed even at a concentration of 0.02%, and its efficacy at 0.1% was equal to that of 1% bifonazole cream. The efficacy of short-term therapy with 1% luliconazole cream, which is used for clinical management, was investigated using the tinea corporis model (4- and 8-day treatment regimens) and the tinea pedis model (7- and 14-day treatment regimens). The 1% luliconazole cream completely eradicated the fungus in half or less of the treatment time required for 1% terbinafine cream and 1% bifonazole cream, as determined by a culture assay for both models. These results clearly indicate that 1% luliconazole cream is sufficiently potent for short-term treatment for dermatophytosis compared to existing drugs. Luliconazole is expected to be useful in the clinical management of dermatophytosis. PMID:22391525

Ice recrystallization inhibition in ice cream as affected by ice structuring proteins from winter wheat grass.

PubMed

Ice recrystallization in quiescently frozen sucrose solutions that contained some of the ingredients commonly found in ice cream and in ice cream manufactured under commercial conditions, with or without ice structuring proteins (ISP) from cold-acclimated winter wheat grass extract (AWWE), was assessed by bright field microscopy. In sucrose solutions, critical differences in moisture content, viscosity, ionic strength, and other properties derived from the presence of other ingredients (skim milk powder, corn syrup solids, locust bean gum) caused a reduction in ice crystal growth. Significant ISP activity in retarding ice crystal growth was observed in all solutions (44% for the most complex mix) containing 0.13% total protein from AWWE. In heat-shocked ice cream, ice recrystallization rates were significantly reduced 40 and 46% with the addition of 0.0025 and 0.0037% total protein from AWWE. The ISP activity in ice cream was not hindered by its inclusion in mix prior to pasteurization. A synergistic effect between ISP and stabilizer was observed, as ISP activity was reduced in the absence of stabilizer in ice cream formulations. A remarkably smoother texture for ice creams containing ISP after heat-shock storage was evident by sensory evaluation. The efficiency of ISP from AWWE in controlling ice crystal growth in ice cream has been demonstrated.

Consumer preferences towards plant-based food have shifted significantly due to sustainable and healthy reasons. Dairy products consist of high Saturated Fatty Acid (SFA) and overconsumption of SFA could lead to cardiovascular diseases. Avocado contains high levels of fat dominated by Monounsaturated Fatty Acid (MUFA) and phytosterol that have the potential as a plant-based fat source to substitute dairy-fat in ice cream. The objective of this study was to analyze the physicochemical, rheological and sensorial properties of ice cream substituted with different concentrations of avocado paste ranging from 0%, 25%, 50%, 75% and 100% respectively against dairy fat to produce non-dairy fat ice cream. The psychochemical properties and total fat were determined. Sensorial quality and hedonic attributes of ice cream were investigated using 60 semi-trained panelists. There were significant differences (p<0.05) for overrun, melting rate, and viscosity of the ice cream substituted with avocado paste. The addition of avocado paste lead to the increase in viscosity and hardness of the ice cream significantly (p<0.05) while the sensorial properties for airiness and creaminess were perceived the same (p>0.05). The addition of 50% avocado paste was the most preferred among the panelists. Avocado could provide a potential substitution for dairy-fat in ice cream.

The aim of this study was to assess the effect in the enamel demineralization of low-intensity infrared laser (λ=810 nm, 100 mW/cm2, 90 sec, 4.47 J/cm2, 9 J) with or without photodynamic cream fluorinated or not fluorinated, using Optical Coherence Tomography (OCT). Background data: Lasers can be used as tools for the prevention of tooth enamel demineralization. All enamel specimens (n= 105) were analyzed using OCT at baseline, and randomly assigned into seven groups (n=15): C (+), laser application; C(-), no treatment; (F), acid fluoride gel; cream (IV); cream and neutral fluoride (IVF); cream and laser (IVL); and cream with neutral fluoride+ laser (IVFL). The specimens were submitted to all kind of treatments before demineralizing pH cycling challenge and were reanalyzed. ANOVA and Tukey's multiple comparative analysis (p <0.01) demonstrated a greater delta attenuation between baseline and post challenge for C + (0.034 +/- 0.011) compared to IVF (0.016 +/- 0.007) F (0.018 +/- 0.010) IVFL (0.019 +/- 0.008), and IVL (0.014 +/- 0.010). The cream laser group (IVL) also showed lower delta (0.014 +/- 0.010) compared to C - (0.025 +/- 0.008). The OCT technique demonstrated that cream associated with laser showed the lowest quantitative enamel mineral looses after cariogenic challenge.

To examine the initial viscosity and adhesive strength of modern denture adhesives in vitro. Three cream-type denture adhesives (Poligrip S, Corect Cream, Liodent Cream; PGS, CRC, LDC) and three powder-type denture adhesives (Poligrip Powder, New Faston, Zanfton; PGP, FSN, ZFN) were used in this study. The initial viscosity was measured using a controlled-stress rheometer. The adhesive strength was measured according to ISO-10873 recommended procedures. All data were analyzed independently by one-way analysis of variance combined with a Student-Newman-Keuls multiple comparison test at a 5% level of significance. The initial viscosity of all the cream-type denture adhesives was lower than the powder-type adhesives. Before immersion in water, all the powder-type adhesives exhibited higher adhesive strength than the cream-type adhesives. However, the adhesive strength of cream-type denture adhesives increased significantly and exceeded the powder-type denture adhesives after immersion in water. For powder-type adhesives, the adhesive strength significantly decreased after immersion in water for 60 min, while the adhesive strength of the cream-type adhesives significantly decreased after immersion in water for 180 min. Cream-type denture adhesives have lower initial viscosity and higher adhesive strength than powder type adhesives, which may offer better manipulation properties and greater efficacy during application.

Despite its effectiveness in treating primary axillary hyperhidrosis (PAH), topical botulinum toxin type A (BTX-A) is highly resistant to transdermal absorption. Topical BTX-A liposomal cream is recommended as a novel, noninvasive modality to enhance skin penetration. To evaluate the efficacy and safety of topical BTX-A liposomal cream in comparison with liposomal vehicle cream alone in the treatment of PAH. A prospective, randomized, double-blinded, split-site study was conducted in 20 subjects, aged 18 to 50 years, all of whom had symmetrical axillary sweating with Hyperhidrosis Disease Severity Scale scores between 2 to 4. All subjects were double-blinded to treatment regimens and randomly given 2 bottles, one containing topical BTX-A liposomal cream and one containing the vehicle cream without BTX-A, to be applied consistently to the same axilla nightly for 7 consecutive days. Clinical improvement and adverse reactions were evaluated at every follow-up visit. Axillary skin treated with topical BTX-A demonstrated superior sweat reduction and patient satisfaction to vehicle cream-treated axillary skin, with clinical and statistical significance, at baseline, weeks 2, 4, 6, and 8 of follow-up, without adverse effects. Topical BTX-A liposomal cream pharmaceutically enhances drug delivery, is painless, cost-effective, and overall an innovative treatment of PAH.

Neem cream was used as mosquito repellent to provide protection against Aedes albopictus, Ae. aegypti, Culex quinquefasciatus, Anopheles culicifacies and An. subpictus mosquitoes. The application of neem cream on exposed body parts @2.0 gm/person showed 78 (range 65-95), 89 (range 66-100) and 94.4 (range 66-100) per cent protection against Aedes, Culex and Anopheles mosquitoes respectively. Significant difference was observed between neem cream treated and untreated group of population for Aedes mosquitoes (p < 0.001). Application of neem cream was found to be a safe and suitable alternative to insecticide impregnated coils for personal protection against mosquitoes and one application was 68% effective for four hours.

In April 2013, a food poisoning outbreak caused by staphylococcal enterotoxins (SEs) in ice-cream occurred in Freiburg, Germany, among the 31 participants of a christening party. Of the 13 cases, seven were hospitalized or obtained ambulatory treatment. Different types of ice-cream, which was freshly produced at the hotel where the party took place, were found to contain SE and high amounts of coagulase positive staphylococci. Enterotoxigenic Staphylococcus aureus strains isolated from ice-cream and human cases were of the same spa-type (t127), harboured the sea gene and displayed identical phenotypic resistance-, Fourier transform infrared spectroscopy- (FT-IR) and microarray-profiles. Despite the strong microbiological and epidemiological evidence of ice-cream being the incriminated food vehicle of the outbreak, a common source of S. aureus from the ice-cream could not be deduced. As none of the employees carried the outbreak strain, either the equipment used for the production of the ice-cream or a contaminated ingredient is the most likely introduction source.

The macrocycle family of molecules called cucurbit[n]urils are potential drug delivery vehicles as they are able to form host-guest complexes with many different classes of drugs. This study aimed to examine the utility of Cucurbit[6]uril (CB[6]) in topical cream-based formulations for either localised treatment or for transdermal delivery. Cucurbit[6]uril was formulated into both buffered cream aqueous- and oily cream-based dosage forms. The solid state interaction of CB[6] with other excipients was studied by differential scanning calorimetry and the macrocycle's transdermal permeability was determined using rat skin. Significant solid state interactions were observed between CB[6] and the other dosage form excipients. At concentrations up to 32% w/w the buffered aqueous cream maintained its normal consistency and could be effectively applied to skin, but the oily cream was too stiff and is not suitable as a dosage form. Cucurbit[6]uril does not permeate through skin; as such, the results imply that cucurbituril-based topical creams may potentially only have applications for localised skin treatment and not for transdermal drug delivery.

The present study was carried out to enhance shelf life of pasteurized cream using Echinophora platyloba essential oil (EEO) and lycopene. For this purpose, two concentrations of EEO (0.10% and 0.50%) and lycopene (20 and 50 ppm) alone and together as combinations were added in pasteurized creams and analyzed for microbial characteristics, sensorial properties and lipid stability during storage at 4 ˚C and 25 ˚C for 14 days. Results of microbial and chemical analyses of experimental pasteurized creams showed that pasteurized creams treated with combinations of the EEO and lycopene in their higher concentrations had the best microbial and chemical properties and the most stability than control during storage (p < 0.05). Results of sensorial evaluation demonstrated that all treatments had favorable overall acceptability, even though, the best sensorial properties were observed in creams with combinations of EEO and lycopene in their lower concentrations. Therefore, based on the results of the present study, application of EEO and lycopene as natural preservatives is especially recommend in high fat dairy products such as butter and cream.

The presence of total and fecal coliforms, E. coli, Listeria sp and Salmonella sp. was evaluated in 65 samples of both commercial and homemade ice cream. 37.1% of homemade ice cream and 20% of commercial ice cream did not fulfill the international standard for total coliforms. At the same time 82.9% of home made samples and 56.7% of commercial ones presented fecal coliforms. E. coli was found in 51.4% of home made samples and 26.7% of commercial ones. Sixteen Listeria sp. isolates were obtained, 50% corresponded to Listeria monocytogenes and 50% to L. innocua. The overall presence of L. monocytogenes in ice cream samples was of 12.3% and it was isolated in all cases, from homemade ice cream samples. Salmonella was not isolated from the samples analyzed. Although the results obtained show an important improvement in the quality of ice cream, compared with a previous work done also in Costa Rica, further efforts shall be done, in order to offer safe products to consumers.

Temporal effects of dairy and vegetable fats (0 to 18%) on perception of strawberry flavor release and melting of ice cream were studied using the time intensity sensory method. Also, aroma and flavor attributes of the ice cream samples were evaluated. Only slight effects of fat on the rate of flavor release and flavor intensity were perceived. A slightly faster flavor release from the vegetable fat compared with dairy fat was noticed. Polydextrose and maltodextrin as bodying agents in the fat-free ice cream significantly increased flavor release and melting rate of the ice cream. Increasing fat content slightly retarded melting of ice cream in the mouth. No significant effect of the fat quality on perceived melting was noticed. Significant differences in aroma and flavor attributes of the fat-free and other samples were perceived. Intensity and sharpness of the strawberry aroma and flavor were greater in fat-free samples and they were perceived as nontypical. Fattiness and creaminess were highly correlated. Maltodextrin and polydextrose increased perceived fattiness and creaminess of fat-free ice cream.

The present study was undertaken to study the sunscreen activity of herbal formulation. There is no evidence of the sun protection factor (SPF) studies on essential oil of Calendula flowers (Calendula officinalis L., Asteraceae). The study investigates the in vitro SPF by ultraviolet specrtophotometry method of Calendula flower oil in a cream formulation. Calendula oil was isolated by Clavenger's apparatus, compositions were identified by GC-MS and the cream of calendula flower oil was prepared by homogenization method followed by evaluation for physical parameters. The sun protection factor of cream was evaluated by in vitro method employing UV-visible spectrophotometer (Shimazdu-1600). The SPF of Calendula oil in cream formulation exhibited good activity (SPF = 14.84 ± 0.16). Finding of this study suggested that calendula oil cream can be used to protect the skin from UV radiations in form of sunscreen cream and to maintain the natural pigmentation of the skin.

In this paper we describe the use of CREAM and CEMonitor services for job submission and management within the gLite Grid middleware. Both CREAM and CEMonitor address one of the most fundamental operations of a Grid middleware, that is job submission and management. Specifically, CREAM is a job management service used for submitting, managing and monitoring computational jobs. CEMonitor is an event notification framework, which can be coupled with CREAM to provide the users with asynchronous job status change notifications. Both components have been integrated in the gLite Workload Management System by means of ICE (Interface to CREAM Environment). These software components have been released for production in the EGEE Grid infrastructure and, for what concerns the CEMonitor service, also in the OSG Grid. In this paper we report the current status of these services, the achieved results, and the issues that still have to be addressed.

Ice recrystallization inhibition in ice cream by propylene glycol monostearate.

PubMed

Aleong, J M; Frochot, S; Goff, H D

2008-11-01

The effectiveness of propylene glycol monostearate (PGMS) to inhibit ice recrystallization was evaluated in ice cream and frozen sucrose solutions. PGMS (0.3%) dramatically reduced ice crystal sizes in ice cream and in sucrose solutions frozen in a scraped-surface freezer before and after heat shock, but had no effect in quiescently frozen solutions. PGMS showed limited emulsifier properties by promoting smaller fat globule size distributions and enhanced partial coalescence in the mix and ice cream, respectively, but at a much lower level compared to conventional ice cream emulsifier. Low temperature scanning electron microscopy revealed highly irregular crystal morphology in both ice cream and sucrose solutions frozen in a scraped-surface freezer. There was strong evidence to suggest that PGMS directly interacts with ice crystals and interferes with normal surface propagation. Shear during freezing may be required for its distribution around the ice and sufficient surface coverage.

Herbal plants are a major source of raw material for traditional medicines. Recently there has been an increase of interest to study the therapeutic potential of herbal plants as herbal care products. In this study, a preliminary study on the formulation of neem (Azadirachta Indica) ointment and cream have been conducted. The neem leaves were extracted and formulated into ointment and cream. The raw neem extract is added into the ointment and cream bases at four different concentrations (0% w/w, 0.5% w/w, 1% w/w and 2% w/w) and stored at three different storage temperatures (4°C, 25°C and 45°C). The semambu ointment and cream formulated were evaluated in terms of their colour and spreadability. It has been found that the extract content and storage temperature influence the colour and spreadability of the formulated neem ointment and cream.

The effect of different overrun levels on the sensory acceptance and survival of probiotic bacteria in ice cream was investigated. Vanilla ice creams supplemented with Lactobacillus acidophilus were processed with overruns of 45%, 60%, and 90%. Viable probiotic bacterial counts and sensory acceptance were assessed. All the ice creams presented a minimum count of 6 log CFU/g at the end of 60 d of frozen storage. However, higher overrun levels negatively influenced cell viability, being reported a decrease of 2 log CFU/g for the 90% overrun treatment. In addition, it was not reported an influence about acceptability with respect to appearance, aroma, and taste of the ice creams (P > 0.05). Overall, the results suggest that lower overrun levels should be adopted during the manufacture of ice cream in order to maintain its probiotic status through the shelf life. © 2012 Institute of Food Technologists®

The purpose of this paper is to investigate some quality attributes of low fat ice cream (LFIC) substituted with hulless barley flour (HBF) and barley ß-glucan (BBG). The methodology included in this paper is based on adding HBF (1, 2, 3 and 4 %) as a partial substitution of skim milk powder (SMP) and BBG (0.40 %) as a complete substitution of carboxy methyl cellulose (CMC). All mixes and resultant ice cream samples were evaluated for their physicochemical properties as well as the sensory quality attributes.The results indicated that substitution of SMP with HBF significantly increased total solids (TS), fat and crude fiber, while crude protein and ash significantly decreased in ice cream mixes. BBG exhibited the same manner of control. Specific gravity was gradually increased with adding HBFand BBG in the mixes and therefore the overrun percent was significantly changed in the resultant ice cream. Adding HBF in ice cream formula led to significant decrease in acidity with higher freezing point and the product showed higher ability to meltdown. BBG treatment showed the same trend of control. Values of flow time and viscosity significantly increased with increasing HBF in the ice cream mixes, but these values significantly decreased in BBG mix. The time required to freeze ice cream mixes was decreased with increasing the ratio of HBF but, increased in BBG treatment. The substitution of SMP with 1 and 2 % HBF significantly (P ≤ 0.05) enhanced sensory attributes of ice cream samples. While, BBG treatment achieved mild score and acceptability.

Pomegranate peel rich in phenolics, and pomegranate seed which contain a conjugated fatty acid namely punicic acid in lipid fraction remain as by-products after processing the fruit into juice. Ice cream is poor in polyunsaturated fatty acids and phenolics, therefore, this study was conducted to improve the functional properties of ice cream by incorporating pomegranate peel phenolics and pomegranate seed oil. Incorporation of the peel phenolics into ice cream at the levels of 0.1% and 0.4% (w/w) resulted in significant changes in the pH, total acidity, and color of the samples. The most prominent outcomes of phenolic incorporation were sharp improvements in antioxidant and antidiabetic activities as well as the phenolic content of ice creams. Replacement of pomegranate seed oil by milk fat at the levels of 2.0% and 4.0% (w/w) increased the conjugated fatty acid content. However, perception of oxidized flavor increased with the additional seed oil. When one considers the functional and nutritional improvements in the enrichment of the ice cream together with overall acceptability results of the sensory analysis, then it follows from this study that ice creams enriched with pomegranate peel phenolics up to 0.4% (w/w) and pomegranate seed oil up to 2.0% (w/w) could be introduced to markets as functional ice cream. Enrichment of ice creams with pomegranate by-products might provide consumers health benefits with striking functional properties of punicalagins in pomegranate peel, and punicic acid in pomegranate seed oil. © 2013 Institute of Food Technologists®

The development of structure in ice cream, characterized by its smooth texture and resistance to collapse during melting, depends, in part, on the presence of solid fat during the whipping and freezing steps. The objective of this study was to investigate the potential application of 10% rice bran wax (RBW) oleogel, comprised 90% high-oleic sunflower oil and 10% RBW, to replace solid fat in ice cream. A commercial blend of 80% saturated mono- and diglycerides and 20% polysorbate 80 was used as the emulsifier. Standard ice cream measurements, cryo-scanning electron microscopy (cryo-SEM), differential scanning calorimetry (DSC), and transmission electron microscopy (TEM) were used to evaluate the formation of structure in ice cream. RBW oleogel produced higher levels of overrun when compared to a liquid oil ice cream sample, creating a lighter sample with good texture and appearance. However, those results were not associated with higher meltdown resistance. Microscopy revealed larger aggregation of RBW oleogel fat droplets at the air cell interface and distortion of the shape of air cells and fat droplets. Although the RBW oleogel did not develop sufficient structure in ice cream to maintain shape during meltdown when a mono- and diglycerides and polysorbate 80 blend was used as the emulsifier, micro- and ultrastructure investigations suggested that RBW oleogel did induce formation of a fat globule network in ice cream, suggesting that further optimization could lead to an alternative to saturated fat sources for ice cream applications. © 2013 Institute of Food Technologists®

Radionuclide dispersion analysis is part of an important reactor safety analysis. From the analysis it can be obtained the amount of doses received by radiation workers and communities around nuclear reactor. The radionuclide dispersion analysis under normal operating conditions is carried out using the PC-CREAM code, and it requires input data such as source term and population distribution. Input data is derived from the output of another program that is PWR-GALE and written Population Distribution data in certain format. Compiling inputs for PC-CREAM programs manually requires high accuracy, as it involves large amounts of data in certain formats and often errors in compiling inputs manually. To minimize errors in input generation, than it is make coupling program for PWR-GALE and PC-CREAM programs and a program for writing population distribution according to the PC-CREAM input format. This work was conducted to create the coupling programming between PWR-GALE output and PC-CREAM input and programming to written population data in the required formats. Programming is done by using Python programming language which has advantages of multiplatform, object-oriented and interactive. The result of this work is software for coupling data of source term and written population distribution data. So that input to PC-CREAM program can be done easily and avoid formatting errors. Programming sourceterm coupling program PWR-GALE and PC-CREAM is completed, so that the creation of PC-CREAM inputs in souceterm and distribution data can be done easily and according to the desired format.

Antimicrobial potency of herbal extracts is well known. The review of patents and research articles revealed that several herbal extracts have been employed in the formulation of topical products such as creams, exclusive of the cream reported in the present study. 0ur previous study has established antimicrobial potency of supercritical carbon dioxide extracts of tuberose flowers, better known for its sweet fragrance. The present work focuses on formulating a topical antimicrobial herbal cream with methyl eugenol (principal antimicrobial compound) rich - supercritical carbon dioxide extract of tuberose flowers, having good combination of phytochemical and antimicrobial potencies. Supercritical carbon dioxide parameters such as temperature, pressure and time were optimized using full factorial experimental design to obtain methyl eugenol-rich extracts. A cream was formulated using the extract having the best combination of phytochemical and antimicrobial potencies and was assayed further for in vitro antimicrobial potency; physiochemical and sensory properties. Two commercial antimicrobial cream samples were used as reference samples in the study. The extract obtained at 40°C, 10 MPa, 135 min at 1 L min-1 flow rate of gaseous C02 showed the best combination of phytochemical and antimicrobial potencies and was used for formulation of herbal creams. The cream formulated with 5% w/w of extract arrested growth of the common human skin pathogen Staphylococcus aureus and showed stable physiochemical properties and high sensory appeal for a year. The cream could be considered as a 'finished herbal product&' in compliance with the World Health 0rganization guidelines.

Aloe vera is a medicinal plant that has been traditionally used to accelerate wound healing. Olive oil is also a natural product that may contribute to wound healing owing to its antimicrobial and anti-inflammatory effects. The present study aimed to evaluate the effect of an Aloe vera-olive oil (AVO) combination cream on the healing process of chronic wounds. In this randomised, double-blind, comparator-controlled, parallel-group trial, patients with chronic wounds were treated with either AVO cream or phenytoin cream as the standard treatment for a period of 30 days. Wound healing was evaluated using Bates-Jensen assessment tool and the severity of pain was assessed using a visual analogue scale (VAS). After initial assessment, 60 patients with chronic wounds (41 with pressure ulcer, 13 with diabetic wounds and 6 with venous ulcers), were recruited and randomised into 2 groups of 30. After 30 days of treatment, significant improvements in the wound size, depth, and edges; necrotic tissue type and amount; exudate type and amount; colour of wound surroundings; and peripheral tissue oedema score were observed in the AVO cream group (p<0.001). The total score of wound healing showed significant improvement with both AVO (p<0.001) and phenytoin (p<0.01) creams, although AVO was more efficacious (p<0.001). Likewise, although both treatments reduced the initial VAS score, the efficacy of AVO was significantly greater (p<0.001). AVO cream significantly accelerates biological healing of chronic wounds and helps to reduce pain severity with a higher efficacy compared with phenytoin cream.

Ice cream is a complex food matrix that contains multiple physical phases. Removal of 1 ingredient may affect not only its physical properties but also multiple sensory characteristics that may or may not be important to consumers. Fat not only contributes to texture, mouth feel, and flavor, but also serves as a structural element. We evaluated the effect of replacing fat with maltodextrin (MD) on select physical properties of ice cream and on consumer acceptability. Vanilla ice creams were formulated to contain 6, 8, 10, 12, and 14% fat, and the difference was made up with 8, 6, 4, 2, and 0% maltodextrin, respectively, to balance the mix. Physical characterization included measurements of overrun, apparent viscosity, fat particle size, fat destabilization, hardness, and melting rate. A series of sensory tests were conducted to measure liking and the intensity of various attributes. Tests were also conducted after 19 weeks of storage at -18°C to assess changes in acceptance due to prolonged storage at unfavorable temperatures. Then, discrimination tests were performed to determine which differences in fat content were detectable by consumers. Mix viscosity decreased with increasing fat content and decreasing maltodextrin content. Fat particle size and fat destabilization significantly increased with increasing fat content. However, acceptability did not differ significantly across the samples for fresh or stored ice cream. Following storage, ice creams with 6, 12, and 14% fat did not differ in acceptability compared with fresh ice cream. However, the 8% fat, 6% MD and 10% fat, 4% MD ice creams showed a significant drop in acceptance after storage relative to fresh ice cream at the same fat content. Consumers were unable to detect a difference of 2 percentage points in fat level between 6 and 12% fat. They were able to detect a difference of 4 percentage points for ice creams with 6% versus 10%, but not for those with 8% versus 12% fat. Removing fat and replacing it with maltodextrin caused minimal changes in physical properties in ice cream and mix and did not change consumer acceptability for either fresh or stored ice cream.

The effect of volatile compounds in white birch sticks obtained from four different geographical locations on the aroma of ice cream mix was investigated. Sensory evaluation, (specifically, a series of warmed-up paired comparisons) was conducted on stick-exposed ice cream mixes to determine whether aroma differences in those mixes could be detected. Batches of ice cream mix were exposed to the sticks and aged for 6 d at 4 degrees C and then assessed by the panelists by pairwise comparison. Findings suggest that differences in aroma of mixes that have been exposed to white birch sticks from four different geographical origins can be distinguished perceptually.

Dexpanthenol enhances skin barrier repair and reduces inflammation after sodium lauryl sulphate-induced irritation.

PubMed

Proksch, E; Nissen, H P

2002-12-01

Dexpanthenol-containing creams have been widely used for treatment of lesions (superficial wounds) of the skin and mucous membranes. Dexpanthenol is converted in tissues to pantothenic acid, a component of coenzyme A. Coenzyme A catalyses early steps in the synthesis of fatty acids and sphingolipids which are of crucial importance for stratum corneum lipid bilayers and cell membrane integrity. In the present study, the effects were examined of a dexpanthenol-containing cream on skin barrier repair, stratum corneum hydration, skin roughness, and inflammation after sodium lauryl sulphate (SLS)-induced irritation. Irritation was induced by application of SLS in patch test chambers. The dexpanthenol-contaming cream or the vehicle were applied twice daily and barrier repair, hydration, roughness, and inflammation of the skin were determined by using biophysical methods. Significantly accelerated skin barrier repair was found in treatments with the dexpanthenol-containing cream (verum) compared with vehicle-treated (placebo) or untreated skin. Both verum and placebo showed an increase in stratum corneum hydration, but significantly more so with the dexpanthenol-containing cream. Both creams reduced skin roughness, but again the verum was superior. The dexpanthenol-containing cream significantly reduced skin redness as a sign of inflammation in contrast to the vehicle, which produced no effect. Treatment with a dexpanthenol-containing cream showed significantly enhanced skin barrier repair and stratum corneum hydration, while reducing skin roughness and inflammation.

Survival of Lactobacillus acidophilus and Bifidobacterium bifidum in ice cream for use as a probiotic food.

Hekmat, S; McMahon, D J

1992-06-01

Probiotic ice cream was made by fermenting a standard ice cream mix with Lactobacillus acidophilus and Bifidobacterium bifidum cultures and then freezing the mix in a batch freezer. Survival of the L. acidophilus and B. bifidum, as well as beta-galactosidase activity, was monitored during 17 wk of frozen storage at -29 degrees C. After freezing of the fermented mix, bacterial counts were 1.5 x 10(8) cfu/ml for L. acidophilus and 2.5 x 10(8) cfu/ml for B. bifidum. Seventeen weeks after freezing, these counts had decreased to 4 x 10(6) and 1 x 10(7) cfu/ml, respectively. During the same period, beta-galactosidase activity decreased from 1800 to 1300 units/ml. Probiotic ice cream was prepared at pH 5.0, 5.5, and 6.0 to determine consumer preferences and was compared with standard Utah State University "Aggie" ice cream. All samples were strawberry-flavored and were evaluated by 88 judges. The preferred pH of probiotic ice cream, based on overall acceptance, was pH 5.5. We demonstrated that probiotic ice cream is a suitable vehicle for delivering beneficial microorganisms such as L. acidophilus and B. bifidum to consumers. The bacteria can be grown to high numbers in ice cream mix and remain viable during frozen storage.

Owing to the growing resistance among isolates of Candida species to usual antifungal agents and the well-known therapeutic potential of curcumin, the purpose of this study was to develop and validate a vaginal formulation containing this substance and to evaluating its effectiveness in the treatment of experimental vulvovaginal candidiasis METHODS: Curcumin was incorporated in a vaginal cream in three concentrations (0.01, 0.1 and 1.0%). The different concentrations of the cream and its controls were intravaginally administered in an immunosuppressed rat model to evaluate the efficacy in the treatment of experimental vulvovaginal candidiasis. Samples of the cream were also subjected to centrifugation and physical stability tests and an analytical method for quantification of curcumin was validated based on HPLC RESULTS: The formulation was stable and the HPLC method could be considered suitable for the quantitative determination of curcumin in the cream. After six days of pre-clinical study, the number of infected animals was 1/6 in all groups treated with curcumin vaginal cream and the fungal burden showed a progressive reduction. Reduction of the inflammatory infiltrate was observed in the group treated with 1.0% cream CONCLUSION: Vaginal cream containing curcumin could be considered a promising effective antifungal medicine in the treatment of vulvovaginal candidiasis.

2013-12-01

The objective of this study was to investigate the influence of emulsifiers, waxes, fat concentration, and processing conditions on the application of wax oleogel to replace solid fat content and create optimal fat structure in ice cream. Ice creams with 10% or 15% fat were formulated with rice bran wax (RBW), candelilla wax (CDW), or carnauba wax (CBW) oleogels, containing 10% wax and 90% high-oleic sunflower oil. The ice creams were produced using batch or continuous freezing processes. Transmission electron microscopy (TEM) and cryo-scanning electron microscopy were used to evaluate the microstructure of ice cream and the ultrastructure of oleogel droplets in ice cream mixes. Among the wax oleogels, RBW oleogel had the ability to form and sustain structure in 15% fat ice creams when glycerol monooleate (GMO) was used as the emulsifier. TEM images revealed that the high degree of fat structuring observed in GMO samples was associated with the RBW crystal morphology within the fat droplet, which was characterized by the growth of crystals at the outer edge of the droplet. Continuous freezing improved fat structuring compared to batch freezing. RBW oleogels established better structure compared to CDW or CBW oleogels. These results demonstrate that RBW oleogel has the potential to develop fat structure in ice cream in the presence of GMO and sufficiently high concentrations of oleogel. © 2013 Institute of Food Technologists®

2014-08-01

Stabilizers are used in ice cream to increase mix viscosity, promote smooth texture, and improve frozen stability. In this study, the effects of varying concentrations (0.00%, 0.15%, 0.30%, and 0.45%) of okra cell wall (OKW) and its corresponding water-soluble polysaccharide (OKP) on the physical characteristics of ice cream were determined. Ice cream mix viscosity was measured as well as overrun, meltdown, and consumer acceptability. Ice recrystallization was determined after ice cream was subjected to temperature cycling in the range of -10 to -20 °C for 10 cycles. Mix viscosity increased significantly as the concentrations of OKW and OKP increased. The addition of either OKW or OKP at 0.15% to 0.45% significantly improved the melting resistance of ice cream. OKW and OKP at 0.15% did not affect sensory perception score for flavor, texture, and overall liking of the ice cream. OKW and OKP (0.15%) reduced ice crystal growth to 107% and 87%, respectively, as compared to 132% for the control (0.00%). Thus, our results suggested the potential use of OKW and OKP at 0.15% as a stabilizer to control ice cream quality and retard ice recrystallization. OKP, however, at 0.15% exhibited greater effect on viscosity increase and on ice recrystallization inhibition than OKW. © 2014 Institute of Food Technologists®

Studies on Physical and Sensory Properties of Premium Vanilla Ice Cream Distributed in Korean Market.

PubMed

Choi, Mi-Jung; Shin, Kwang-Soon

2014-01-01

The object of this study was to investigate the difference in physical and sensory properties of various premium ice creams. The physical properties of the various ice creams were compared by manufacturing brand. The water contents of the samples differed, with BR having the highest value at 60.5%, followed by NT and CS at 57.8% and 56.9%, respectively. The higher the water content, the lower Brix and milk fat contents in all samples. The density of the samples showed almost similar values in all samples (p>0.05). The viscosity of each ice cream had no effect on the water content in any of the brands. Before melting of the ice cream, the total color difference was dependent on the lightness, especially in the vanilla ice cream, owing to the reflection of light on the surface of the ice crystals. The CS product melted the fastest. In the sensory test, CS obtained a significantly higher sweetness intensity score but a lower score for color intensity, probably due to the smaller difference in total color, by which consumers might consider the color of CS as less intense. From this study, the cold chain system for ice cream distribution might be important to decide the physical properties although the concentration of milk fat is key factor in premium ice cream.

Low-dose irradiation as a measure to improve microbial quality of ice cream.

Kamat, A; Warke, R; Kamat, M; Thomas, P

2000-12-05

The present study was undertaken to investigate the efficacy of low-dose irradiation to improve the microbial safety of ice cream. Initially three different flavors (vanilla, strawberry and chocolate) of ice cream were exposed, at -72 degrees C, to doses of 1, 2, 5, 10 and 30 kGy to gamma-radiation. Irradiation at 1 kGy resulted in reduction of microbial population by one log cycle, thus meeting the requirement limits prescribed by Bureau of Indian Standards. Pathogens such as Listeria monocytogenes 036, Yersinia enterocoliticta 5692 and Escherichia coli O157:H19, respectively, showed the D10 values 0.38, 0.15 and 0.2 kGy in ice cream at -72 degrees C suggesting the efficacy of low doses (1 kGy) in eliminating them. Sensory evaluation studies of ice cream irradiated at 1, 2, 3 and 5 kGy by a 15 member panel demonstrated that doses higher than 2 kGy irradiation induced off-odour and an aftertaste was evident in vanilla ice cream. A radiation dose of 1 kGy was sufficient to eliminate the natural number of pathogens present in the ice cream. No statistically significant differences were observed in the sensory attributes of all the three flavours of ice cream either unirradiated or exposed to 1 kGy (P < 0.05).

Denture-wearing favours the growth of Candida. In view of the fact that many denture wearers regularly use adhesives to enhance denture retention, stability and function, the aim of this work was to study the effect of denture adhesives on Candida albicans growth in vitro. The denture adhesives tested were Corega(®) cream, Kukident(®) cream, Novafix(®) cream, Polident(®) cream, Protefix(®) cream, Steradent(®) cream, Aderyn(®) powder, Corega(®) ultra powder, Protefix(®) powder and Corega(®) strip. C. albicans growth curves were obtained in the presence or absence of a 1% solution of the denture adhesive diluted in Sabouraud broth. Macro- and microscopic morphological changes in C. albicans were analysed, as was microbial contamination of the denture adhesive. Most of the denture adhesives studied induced morphological changes in C. albicans cells and colonies, but only two had any significant inhibitory effect on yeast growth. Kukident(®) cream markedly inhibited C. albicans growth in a concentration-dependent way, reducing the growth rate by 95%, whereas Corega(®) cream also inhibited C. albicans growth but in a non-concentration-dependent way, reducing the growth rate by 37%. In addition, denture adhesives available as powders had detectable microbial contamination. Some commercially available denture adhesives showed microbial contamination and some had significant inhibitory effect on C. albicans growth. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

Avocado (Persea americana Mill.) seed was often seen as waste and underutilized resources, especially in the food industry. The aim of this research was to modify the structure of avocado seed starch using the cross-linking method, to improve the viscosity stability in the cream soup. In the preliminary research, starch was isolated from the seed and modified by STPP (sodium tripolyphosphate) with 2%, 4%, and 6% concentration and were reacted for 1, 2, and 3 hours. Starches were analyzed for moisture and ash content, paste clarity, gel strength, swelling power, solubility, yield, and degree of whiteness. Based on the analysis results, the best reaction time and STPP concentration was 6% at 1 hour reaction time. Native starch and the best-modified starch were applied in the cream soup and compared with commercial cream soup. Cream soups were analyzed for viscosity stability using viscometer in 0, 1, 3, and 5 hours after storage in room temperature. The result showed that cream soup using modified starch has better viscosity stability than native starch and commercial cream soup after 5 hours storage, which was 181.7 ± 4.85 cP. Sensory analysis showed that cream soup using modified starch was more acceptable than the others. Avocado seed modified starch has phosphate group that strengthen the starch chain to prevent viscosity breakdown.

A washing treatment was applied to caprine cream before churning in order to improve phospholipids and MFGM protein purification from buttermilk and butter serum. Cream obtained from a first separation was diluted with water and separated a second time using pilot plant equipment. Regular and washed creams were churned to produce buttermilk and butter, from which butter serum was extracted. The washing treatment allowed a significant decrease of the casein content. As a result, the phospholipids-to-protein ratios in washed buttermilk and butter serum were markedly increased by 2.1 and 1.7-folds respectively, which represents an advantage for the production of phospholipids concentrates. However, when compared with bovine cream, lower phospholipids-to-protein ratios were observed when the washing treatment was applied to caprine cream. A higher concentration of MFGM protein and a lower retention of phospholipids during washing treatment are responsible for the lower phospholipids-to-protein ratios in buttermilk and butter serum obtained from caprine cream. The phospholipids distribution in the butter making process was similar to the one obtained from bovine regular and washed cream. Phospholipids were preferentially concentrated in the butter serum rather than the buttermilk fraction. This simple approach permitted the production of caprine and bovine butter sera extracts containing up to 180 and 240 g phospholipids/kg sera, respectively, on a dry basis.

In a human acid pain model, which uses continuous intradermal pressure infusion of a phosphate-buffered solution (pH 5.2) to induce localized non-adapting pain, the flow was adjusted to result in constant pain ratings of about 20% or 50% on a visual analog scale (VAS). Six volunteers in each group participated in 4 different placebo-controlled double-blind cross-over studies to measure rapidly evolving cutaneous analgesia from topically applied new ointment formulations of acetylsalicylic acid (ASA) and salicylic acid (SA) as well as of commercial ibuprofen and benzocain creams. Similar, log-linear dose-response curves were found for both ASA and SA, significant in effect at 3 g/kg and higher drug contents and reaching saturation level at 15 or 30 g/kg, respectively, which, 20 min after application, caused a mean pain suppression of 95% using ASA and 80% using SA. Half-maximal effects were achieved using 3 g/kg ASA or 15 g/kg SA. The SA action was also clearly slower to develop. With an increased flow of the acidic buffer, producing lower effective tissue pH and more intense pain, the effect of ASA and SA decreased to 73% pain suppression. A competitive mechanism of both drug effects was suggested by the fact that, with 15 g/kg ASA and SA, pain reduction could be reversed by increasing the buffer flow by a factor of 1.75, on average. Commercial ibuprofen (50 g/kg) and benzocain creams (100 g/kg) were comparably as effective as ASA and SA, but the local anesthetic caused a loss of all cutaneous sensations while the touch threshold (von Frey) under the specific analgesics was the same as under the placebo ointment. Thus, topical applications of non-steroidal anti-inflammatory drugs (NSAIDS) dissolved in different ointment formulations have proven dose-dependently effective and specific in suppressing experimental acidotic pain by a local and competitive mechanism.

The changes in the reproductive barrier between hexaploid wheat ( Triticum aestivum L.) and rye ( Secale cereale L.) can be induced using in situ embryo rescue of abnormal embryos, yielding stable fertile amphidiploid plants. In intergeneric crosses between hexaploid wheat (Triticum aestivum L.) and rye (Secale cereale L.), postzygotic barriers may occur at different stages of hybrid development. One such mechanism is embryo lethality, which is genetically determined by the interaction and expression of two incompatible genes in wheat (Eml-A1) and rye (Eml-R1). Using in vitro culture methods as stressors, we overcame this hybrid lethality. Normal and abnormal embryos were observed to build embryogenic calli and produce regenerated plantlets in a similar manner. The high regenerative capacity of the abnormal embryos led us to conclude that the reproductive barrier in these intergeneric hybrids may have an epigenetic origin that can be easily overcome by culturing immature embryos via callus induction. After colchicine treatment during callus culture, amphidiploid plants were obtained. However, most of these plants did not produce seeds, due mainly to sterility of the pollen but also of the embryo sacs. These findings demonstrate that hybrid sterility affects both male and female gametophytes in plants obtained from abnormal embryos. The key roles of double fertilization and stress factors in the implementation of the apical meristem formation program in embryos from incompatible intergeneric crosses between hexaploid wheat and rye during in vitro culture are discussed. We also propose a hypothetical model for a wheat-rye lethality system involving differential expression of incompatible wheat Eml-A1 and rye Eml-R1b alleles in an identical genetic background.

Herbal cream imparts a chief role in regulating melanin production of skin. The phytoconstituents present in herbal cream impact biological functions of skin and contribute nutrients required for the healthy skin. In the present study, it was envisaged to prepare three batches of herbal cream (HC1, HC2 and HC3) containing ethanol extracts of Emblica officinalis (fruits), Daucus carota (root), Mangifera indica (leaves), Mentha arvensis (leaves), Terminalia arjuna (bark) and Cucumis sativus (fruits) and investigated the prepared cream for inhibitory effect on tyrosinase activity. The herbal cream was formulated by incorporating different ratio of extracts, by using cream base. Each formulation HC1, HC2 and HC3 were segregated into three different formulations (HC1.1, HC1.2, HC1.3, HC2.1, HC2.2, HC2.3, HC3.1, HC3.2 and HC3.3) by incorporating increasing ratio of extract in formulation. The HC3.2 cream produces highest tyrosinase inhibitory effect 65.23 +/- 0.07%, while the HC2.1 exhibited minimum tyrosinase inhibitory effect 26.19 +/- 0.08% compared to other prepared cream. Comparison of the inhibitory activity of the formulations demonstrated that the rank order was HC3.2 > HC3.3 > HC1.2 > HC1.3 > HC3.1 > HC1.1 > HC2.3 > HC2.2 > HC2.1. It has been observed from the result that the formulations of antityrosinase activity were not concentrate dependent. This finding suggests that decrease in antityrosinase activity of HC1 and HC3 might be considering that the incompatibility of the higher extract content with the base of cream. The HC3 produce the maximum inhibitory effects on tyrosinase activity might be due to higher level of polyphenol and flavonoids present in extracts.

To evaluate whether premature infants who received an exclusive human milk (HM)-based diet and a HM-derived cream supplement (cream) would have weight gain (g/kg/d) at least as good as infants receiving a standard feeding regimen (control). In a prospective noninferiority, randomized, unmasked study, infants with a birth weight 750-1250 g were randomly assigned to the control or cream group. The control group received mother's own milk or donor HM with donor HM-derived fortifier. The cream group received a HM-derived cream supplement if the energy density of the HM tested <20 kcal/oz using a near infrared HM analyzer. Infants were continued on the protocol until 36 weeks postmenstrual age. Primary outcomes included growth velocities and amount of donor HM-derived fortifier used. The hypothesis of noninferiority was established if the lower bound of the one-sided 95% CI for the difference in weight velocities exceeded -3 g/kg/day. There were no differences between groups in baseline demographics for the 78 infants studied except racial distribution (P = .02). The cream group (n = 39) had superior weight (14.0 ± 2.5 vs 12.4 ± 3.0 g/kg/d, P = .03) and length (1.03 ± 0.33 vs 0.83 ± 0.41 cm/wk, P = .02) velocity compared with the control group (n = 39). There were no significant differences in amount of fortifier used between study groups. The 1-sided 95% lower bound of the CI for the difference in mean velocity (cream-control) was 0.38 g/kg/d. Premature infants who received HM-derived cream to fortified HM had improved weight and length velocity compared with the control group. HM-derived cream should be considered an adjunctive supplement to an exclusive HM-based diet to improve growth rates in premature infants. Copyright © 2014 The Authors. Published by Elsevier Inc.

Objective Optimal bone mass in early adulthood is achieved through appropriate diet and lifestyle, thereby protecting against osteoporosis and risk of bone fracture in later life. Calcium and vitamin D are essential to build adequate bones, but calcium intakes of many population groups do not meet dietary reference values. In addition, changes in dietary patterns are exacerbating the problem, thereby emphasizing the important role of calcium-rich food products. We have designed a calcium-fortified ice cream formulation that is lower in fat than regular ice cream and could provide a useful source of additional dietary calcium. Calcium absorption from two different ice cream formulations was determined in young adults and compared with milk. Subjects/setting Sixteen healthy volunteers (25 to 45 years of age), recruited from the general public of The Netherlands, participated in a randomized, reference-controlled, double-blind cross-over study in which two test products and milk were consumed with a light standard breakfast on three separate occasions: a standard portion of ice cream (60 g) fortified with milk minerals and containing a low level (3%) of butter fat, ice cream (60 g) fortified with milk minerals and containing a typical level (9%) of coconut oil, and reduced-fat milk (1.7% milk fat) (200 mL). Calcium absorption was measured by the dual-label stable isotope technique. Statistical analysis Effects on calcium absorption were evaluated by analysis of variance. Results Fractional absorption of calcium from the 3% butterfat ice cream, 9% coconut oil ice cream, and milk was 26%±8%, 28%±5%, and 31%±9%, respectively, and did not differ significantly (P=0.159). Conclusions Results indicate that calcium bioavailability in the two calcium-fortified ice cream formulations used in this study is as high as milk, indicating that ice cream may be a good vehicle for delivery of calcium.

The effects of supplementation of oligofructose or inulin on the rheological characteristics and survival of Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 in low-fat ice cream stored at -18 degrees C for 90 d were studied. Addition of oligofructose or inulin to ice cream mix significantly increased apparent viscosity and overrun and developed the melting properties in ice cream during storage (P < 0.05). However, the highest increase in firmness, the lowest change in melting properties, and the longest 1st dripping time were obtained in probiotic ice cream containing inulin (P < 0.05). Some textural properties have also improved especially by the end of storage. Freezing process caused a significant decrease in the viability of Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 (P < 0.05). Oligofructose significantly improved the viability of L. acidophilus La-5 and B. animalis Bb-12 in ice cream mix (P < 0.05). Although the viable numbers for both bacteria decreased throughout the storage, the minimum level of 10(6) CFU/g was maintained for B. animalis Bb-12 in only ice cream with oligofructose during storage.

The primary objective of this study was to evaluate the physicochemical and rheological properties of butter produced by Lactobacillus helveticus fermented cream. The incorporation of putative probiotic - the L. helveticus, to ferment cream prior to butter production was anticipated to alter the nutritional composition of butter. Changes in crude macronutrients and the resultant modification relating to textural properties of butter induced upon metabolic activities of L. helveticus in cream were focused in this research. Fermented butter (LH-butter) was produced by churning the cream that was fermented by lactobacilli at 37 °C for 24 h. Physicochemical analysis, proximate analysis and rheology properties of LH-butter were compared with butter produced using unfermented cream (control). LH-butter showed a significantly (P<0.05) higher fat content and acid value; lower moisture and ash; and was softer than the control. Cream fermentation modified nutritional and textural properties of butter in which LH-butter contained higher health beneficial unsaturated fatty acids than the control and thus rendered the product softer. Its enrichment with probiotics could thus further enhance its functional property. Copyright © 2016 Elsevier Ltd. All rights reserved.

Photocarcinogenesis study of aloe vera [CAS NO. 481-72-1(Aloe-emodin)] in SKH-1 mice (simulated solar light and topical application study).

PubMed

2010-09-01

The popular recognition of the Aloe barbadensis Miller (Aloe vera) plant as a therapeutic dermatologic agent has led to the widespread incorporation of Aloe vera leaf extracts in skincare products. Studies have suggested that Aloe vera in skincare preparations may enhance the induction of skin cancer by ultraviolet radiation. A 1-year study was conducted in mice to determine whether the topical application of creams containing Aloe vera plant extracts (aloe gel, whole leaf, or decolorized whole leaf) or creams containing aloe-emodin would enhance the photocarcinogenicity of simulated solar light (SSL). 1-YEAR STUDY: groups of 36 male and 36 female Crl:SKH-1 (hr -/hr -) hairless mice received topical applications of control cream or creams containing 3% or 6% (w/w) aloe gel, whole leaf, or decolorized whole leaf or 7.46 or 74.6 µg/g aloe-emodin to the dorsal skin region each weekday morning. The mice were irradiated with SSL emitted from filtered 6 kW xenon arc lamps each weekday afternoon. The topical applications of creams and irradiance exposures were conducted 5 days per week for a period of 40 weeks. A 12-week recovery/observation period followed the 40-week treatment/exposure period. Additional groups of 36 male and 36 female mice received no cream and were exposed to 0.00, 6.85, 13.70, or 20.55 mJ⋅CIE/cm2 SSL per day. Mice that received no cream treatment and were exposed to increasing levels of SSL showed significant SSL exposure-dependent decreases in survival and significant increases in the in-life observations of skin lesion onset, incidence, and multiplicity, and significant SSL exposure-dependent increases in the incidences and multiplicities of histopathology-determined squamous cell nonneoplastic skin lesions (squamous hyperplasia and focal atypical hyperplasia) and squamous cell neoplasms (papilloma, carcinoma in situ, and/or carcinoma). Squamous cell neoplasms were not detected in mice that received no SSL exposure. The topical treatment with the control cream of mice that were exposed to SSL did not impart a measurable effect when compared with comparable measurements in mice that received no cream treatment and were exposed to the same level of SSL, suggesting that the control cream used in these studies did not alter the efficiency of the SSL delivered to mice or the tolerability of mice to SSL. The application of aloe gel creams to mice had no effect on body weights, survival, or the in-life observations of skin lesion onset, incidence, or multiplicity. The administration of aloe gel creams to male mice had no effect on the incidences or multiplicities of histopathology-determined squamous cell nonneoplastic skin lesions or neoplasms. Female mice treated with aloe gel creams (3% and 6%) had significantly increased multiplicities of squamous cell neoplasms. There were no treatment-related effects on body weights, survival, or the in-life observations of skin lesion onset, incidence, or multiplicity in mice treated with the whole leaf creams. In male mice exposed to SSL and treated with the 6% whole leaf cream, a significant increase was observed in the multiplicity of squamous cell neoplasms. Female mice exposed to SSL and treated with the 3% whole leaf creams had significantly decreased multiplicity of squamous cell nonneoplastic lesions and significantly increased multiplicity of squamous cell neoplasms. Female mice exposed to SSL and treated with the 6% whole leaf cream had significantly decreased multiplicity of squamous cell nonneoplastic lesions. The application of decolorized whole leaf creams to mice had no effect on body weights, survival, or the in-life observations of skin lesion onset, incidence, or multiplicity. Male mice administered the 3% decolorized whole leaf cream had significantly increased multiplicity of squamous cell neoplasms. Female mice administered the 3% decolorized whole leaf cream had significantly decreased multiplicity of squamous cell nonneoplastic skin lesions and significantly increased multiplicity of squamous cell neoplasms. In female mice that received the 6% decolorized whole leaf cream, there was a significant increase in the multiplicity of squamous cell neoplasms. As with the Aloe vera plant extracts, the application of aloe-emodin creams to mice had no measurable effect on body weights, survival, or the in-life observations of skin lesion onset, incidence, or multiplicity. The administration of aloe-emodin creams to male mice had no effect on the incidence or multiplicity of histopathology-determined nonneoplastic skin lesions or squamous cell neoplasms. Female mice treated with the 74.6 µg/g aloe-emodin cream had significantly decreased multiplicity of histopathology-determined squamous cell nonneoplastic skin lesions and significantly increased multiplicity of squamous cell neoplasms. these experiments investigated the potential of topical application of creams containing extracts of Aloe barbadensis Miller plant (aloe gel, whole leaf, or decolorized whole leaf) or aloe-emodin to alter the photocarcinogenic activity of filtered xenon arc simulated solar light (SSL) in male and female SKH-1 hairless mice. Data on skin lesions were collected both on digital images during the in-life phase and by histopathologic evaluation at necropsy. No effects of creams upon SSL-induced skin lesions were identified from data collected during the in-life phase. ALOE GEL OR ALOE-EMODIN: under the conditions of these studies, there was a weak enhancing effect of aloe gel or aloe-emodin on the photocarcinogenic activity of SSL in female but not in male SKH-1 mice based on an increase in the multiplicity of histopathologically-determined squamous cell neoplasms. under the conditions of these studies, there was a weak enhancing effect of aloe whole leaf or decolorized whole leaf on the photocarcinogenic activity of SSL in both male and female SKH-1 mice based on an increase in the multiplicity of histopathologically-determined squamous cell neoplasms.

To evaluate the caries risk based on the salivary levels of streptococcus mutans in children of 6-12 years of age group before and after consuming probiotic ice-cream containing Bifidobacterium lactis Bb-12 and Lactobacillus acidophilus La-5. A double blind, placebo controlled trial was carried out in 60 children aged between 6 to 12 years with zero decayed, missing, and filled teeth (DMFT). They were randomly divided into two equal groups. Saliva sample were collected before the consumption of ice-cream and Streptococcus mutans count was calculated and recorded as baseline data. For the next seven days both the groups were given ice creams marked as A and B. Saliva samples were collected after ice-cream consumption at the end of study period and also after a washout period of 30 days and again after six months. Samples were inoculated and colonies were counted. On statistical evaluation by students paired t-test, probiotic ice-cream brought significant reduction in the Streptococcus mutans count after seven days of ice-cream ingestion (p<0.001) and also after 30 d of washout period (p<0.001). There was no significant reduction (p=0.076) by normal ice-cream consumption. After six months of the study period in both the groups the salivary levels of Streptococcus mutans was similar to the baseline. Probiotic ice-cream containing Bifidobacterium lactis Bb-12 and Lactobacillus acidophilus La-5 can cause reduction in caries causative organism. The dosage of the probiotic organisms for the long term or synergetic effect on the oral health are still needed to be explored.

This study aimed to investigate the role of in situ exopolysaccharide (EPS) production by EPS(+)Streptococcus thermophilus strains on physicochemical, rheological, molecular, microstructural and sensory properties of ice cream in order to develop a fermented and consequently functional ice-cream in which no stabilizers would be required in ice-cream production. For this purpose, the effect of EPS producing strains (control, strain 1, strain 2 and mixture) and fermentation conditions (fermentation temperature; 32, 37 and 42 °C and time; 2, 3 and 4h) on pH, S. thermophilus count, EPS amount, consistency coefficient (K), and apparent viscosity (η50) were investigated and optimized using single and multiple response optimization tools of response surface methodology. Optimization analyses indicated that functional ice-cream should be fermented with strain 1 or strain mixture at 40-42 °C for 4h in order to produce the most viscous ice-cream with maximum EPS content. Optimization analysis results also revealed that strain specific conditions appeared to be more effective factor on in situ EPS production amount, K and η50 parameters than did fermentation temperature and time. The rheological analysis of the ice-cream produced by EPS(+) strains revealed its high viscous and pseudoplastic non-Newtonian fluid behavior, which demonstrates potential of S. thermophilus EPS as thickening and gelling agent in dairy industry. FTIR analysis proved that the EPS in ice-cream corresponded to a typical EPS, as revealed by the presence of carboxyl, hydroxyl and amide groups with additional α-glycosidic linkages. SEM studies demonstrated that it had a web-like compact microstructure with pores in ice-cream, revealing its application possibility in dairy products to improve their rheological properties.

A method for the determination of 37 fatty acids in natural cream and artificial cream was developed by comprehensive two-dimensional gas chromatography-mass spectrometry (GC×GC-MS). The samples were extracted with toluene and acetyl chloride-methanol (1:9,v/v) solution was added to the extract for fat esterification. Finally, the fatty acids were analyzed by GC×GC-MS. The GC conditions were as follows:a DB-5 column (30 m×0.25 mm×0.25 μm) was set as the 1st dimensional column and a BPX-50 column (2.5 m×0.1 mm×0.25 μm) was the 2nd dimensional column. The primary oven temperature was programmed from 50℃ (held for 2 min) to 180℃ at a rate of 20℃/min, followed by an increase to 250℃ at 2.5℃/min, then raised up to 300℃ (held for 5 min) at 3℃/min. The ion source temperature was 200℃ with auxiliary temperature of 300℃ in scan mode. All fatty acids were separated effectively and determined accurately while the modulation period was 5s and the scan range of MS was m/z 40-385. This procedure was applied to analyze the fatty acids in commercial natural cream and artificial cream from Chinese markets, among which we found the characteristic components in different kinds of samples. Compared with gas chromatography-flame ionization detector (GC-FID), GC×GC-MS method was more sensitive and more components of fatty acids were detected. Conclusively, this work suggests a new technical approach in analyzing fatty acids in natural cream and artificial cream, which is meaningful to ensure the quality identification and safety of natural cream.

The formation of reactive oxygen species (ROS) contributes to the pathogenesis and progression of several diseases. Polyphenols have been shown to be beneficial against ROS. The aim of this study was to evaluate the effects of a natural antioxidant ice cream on oxidative stress, vascular function, and physical performance. In this controlled, single-blind, crossover study, 14 healthy individuals were randomized to consume 100 g of either antioxidant ice cream containing dark cocoa powder and hazelnut and green tea extracts or milk chocolate ice cream (control ice cream). Participants were studied at baseline and 2 h after ingesting ice cream. Serum polyphenols, antioxidant status (ferric-reducing ability of plasma [FRAP]), nitric oxide (NOx) bioavailability, markers of oxidative stress (determination of reactive oxygen metabolites [d-ROMs] and hydrogen peroxide [H 2 O 2 ]), endothelium function (flow-mediated dilation [FMD] and reactive hyperemia index [RHI]), and exercise tolerance (stress test) were assessed, and the double product was measured. Serum polyphenols (P < 0.001), NOx (P < 0.001), FRAP (P < 0.005), FMD (P < 0.001), and RHI (P < 0.05) increased significantly, oxidative stress decreased (d-Roms, P < 0.001; H 2 O 2 , P < 0.001), and the double product (P < 0.001) was improved only after antioxidant ice cream ingestion. No changes were found after control ice cream ingestion. To our knowledge, this is the first study to demonstrate that a natural ice cream rich in polyphenols acutely improved vascular function and physical performance in healthy individuals through a reduction in oxidative stress.

The HACCP system is applied in the present study as a preventive food safety approach to control some hazards appearing in one of the ice cream production plants in Egypt. The problem comprised the presence of bacteriological and some chemical contamination in most of the company products. Before applying the HACCP system, the samples examination showed high total mesophilic plat count in 50% of the samples and high coliform count in all samples compared to the level recommended in the Egyptian standards. The highest staphylococcal count (negative for coagulase test) obtained was that of chocolate (1.3 x 10(4) CFU/g) followed by mango ice cream (l.0 x 10(4) CFU/g). Faecal coliform was only positive in mango ice cream. Additionally, the levels of lead, iron and copper have been determined. Copper was higher than the recommended level in all samples and ranged between 0.46 ppm in pistachio ice cream and 2.48 ppm in chocolate ice cream. Most of the CCPs in the ice cream production were mainly due to improper handling and practices throughout the processing steps and also related to the lack of food hygiene knowledge of the workers. The application of HACCP system has successfully reduced the bacteriological hazards in all samples. After applying the corrective actions, the highest total aerobic plate count (8.0 x 10(4)) was that of Swiss chocolate ice cream which corresponds to 50% of the recommended level by the Egyptian standards. Coliform count was less than 10 in all samples except mango ice cream (43 MPN). A significant decrease in staphylococcal count, faecal coliform and trace metal contamination was also recorded in all samples.

Introduction: To evaluate the caries risk based on the salivary levels of streptococcus mutans in children of 6-12 years of age group before and after consuming probiotic ice-cream containing Bifidobacterium lactis Bb-12 and Lactobacillus acidophilus La-5. Materials and Methods: A double blind, placebo controlled trial was carried out in 60 children aged between 6 to 12 years with zero decayed, missing, and filled teeth (DMFT). They were randomly divided into two equal groups. Saliva sample were collected before the consumption of ice-cream and Streptococcus mutans count was calculated and recorded as baseline data. For the next seven days both the groups were given ice creams marked as A and B. Saliva samples were collected after ice-cream consumption at the end of study period and also after a washout period of 30 days and again after six months. Samples were inoculated and colonies were counted. Results: On statistical evaluation by students paired t-test, probiotic ice-cream brought significant reduction in the Streptococcus mutans count after seven days of ice-cream ingestion (p<0.001) and also after 30 d of washout period (p<0.001). There was no significant reduction (p=0.076) by normal ice-cream consumption. After six months of the study period in both the groups the salivary levels of Streptococcus mutans was similar to the baseline. Conclusion: Probiotic ice-cream containing Bifidobacterium lactis Bb-12 and Lactobacillus acidophilus La-5 can cause reduction in caries causative organism. The dosage of the probiotic organisms for the long term or synergetic effect on the oral health are still needed to be explored. PMID:25859515

As known, fractional CO 2 resurfacing treatments are more effective than non-ablative ones against aging signs, but post-operative redness and swelling prolong the overall downtime requiring up to steroid administration in order to reduce these local systems. In the last years, an increasing interest has been focused on the possible use of probiotics for treating inflammatory and allergic conditions suggesting that they can exert profound beneficial effects on skin homeostasis. In this work, the Authors report their experience on fractional CO 2 laser resurfacing and provide the results of a new post-operative topical treatment with an experimental cream containing probiotic-derived active principles potentially able to modulate the inflammatory reaction associated to laser-treatment. The cream containing DermaACB (CERABEST™) was administered post-operatively to 42 consecutive patients who were treated with fractional CO 2 laser. All patients adopted the cream twice a day for 2 weeks. Grades were given according to outcome scale. The efficacy of the cream containing DermaACB was evaluated comparing the rate of post-operative signs vanishing with a control group of 20 patients topically treated with an antibiotic cream and a hyaluronic acid based cream. Results registered with the experimental treatment were good in 22 patients, moderate in 17, and poor in 3 cases. Patients using the study cream took an average time of 14.3 days for erythema resolution and 9.3 days for swelling vanishing. The post-operative administration of the cream containing DermaACB induces a quicker reduction of post-operative erythema and swelling when compared to a standard treatment.

The present study was undertaken to study the sunscreen activity of herbal formulation. There is no evidence of the sun protection factor (SPF) studies on essential oil of Calendula flowers (Calendula officinalis L., Asteraceae). The study investigates the in vitro SPF by ultraviolet specrtophotometry method of Calendula flower oil in a cream formulation. Calendula oil was isolated by Clavenger's apparatus, compositions were identified by GC–MS and the cream of calendula flower oil was prepared by homogenization method followed by evaluation for physical parameters. The sun protection factor of cream was evaluated by in vitro method employing UV–visible spectrophotometer (Shimazdu-1600). The SPF of Calendula oil in cream formulation exhibited good activity (SPF = 14.84 ± 0.16). Finding of this study suggested that calendula oil cream can be used to protect the skin from UV radiations in form of sunscreen cream and to maintain the natural pigmentation of the skin.

To examine the effect of chocobar ice cream containing bifidobacteria on salivary mutans streptococci and lactobacilli. A double-blind, randomised controlled trial was conducted with 30 subjects (18 to 22 years of age) divided into 2 groups, test (chocobar ice cream with probiotics) and control (chocobar ice cream without probiotics). The subjects were instructed to eat the allotted chocobar ice cream once daily for 18 days. Saliva samples collected at intervals were cultured on Mitis Salivarius agar and Rogosa agar and examined for salivary mutans streptococci and lactobacilli, respectively. The Mann-Whitney U-test, Friedman and Wilcoxon signed-rank tests were used for statistical analysis. Postingestion in the test group, a statistically significant reduction (p < 0.05) of salivary mutans streptococci was recorded, but a non-significant trend was seen for lactobacilli. Significant differences were was also observed between follow-ups. Short-term daily ingestion of ice cream containing probiotic bifidobacteria may reduce salivary levels of mutans streptococci in young adults.

The following strains of bacteria: Lactobacillus rhamnosus B 442, Lactobacillus rhamnosus 1937, and Lactococcus lactis JBB 500 were enriched with magnesium ions using Pulsed Electric Fields. The potentially probiotic strains were added to the mixture in the DVS process and applied for the production of ice cream which were then analyzed physicochemically and microbiologically. Results showed that addition of bacteria enriched with magnesium did not change chemical parameters of the ice cream and did not affect the freezing process, meltability, and hardness. No significant differences were noted in colour of the samples. The ice cream with addition of bacteria enriched with magnesium had higher adhesiveness. The results of viability determination showed that the total number of microorganisms in the ice cream was higher than in the starter cultures. Viability of the bacteria enriched with magnesium in the obtained ice cream was lower in comparison to the control samples. Copyright © 2017 Elsevier Ltd. All rights reserved.

To assess an objective method evaluating the effects of a retinaldehyde-based cream (RA-cream) on solar lentigines; 29 women randomly applied RA-cream on lentigines of one hand and a control cream on the other, once daily for 3 months. A specific method enabling a reliable visualisation of the lesions was proposed, using high-magnification colour-calibrated camera imaging. Assessment was performed using clinical evaluation by Physician Global Assessment score and image analysis. Luminance determination on the numeric images was performed either on the basis of 5 independent expert's consensus borders or probability map analysis via an algorithm automatically detecting the pigmented area. Both image analysis methods showed a similar lightening of ΔL* = 2 after a 3-month treatment by RA-cream, in agreement with single-blind clinical evaluation. High-magnification colour-calibrated camera imaging combined with probability map analysis is a fast and precise method to follow lentigo depigmentation. © 2014 John Wiley & Sons A/S.

Stability conditions and mechanism of cream soaps: role of glycerol.

PubMed

Sagitani, Hiromichi

2014-01-01

Fatty acids, fatty acid potassium soaps, glycerol and water are essential ingredients in the production of stable cream soaps. In this study, the behavior of these components in solution was investigated to elucidate the stability conditions and mechanism of cream soaps. It was determined that the cream soaps were a dispersion of 1:1 acid soap (1:1 molar ratio of potassium soap/fatty acid) crystals in the lamellar gel phase, which has confirmed from the phase behavior diagrams and small angle X-ray scattering data. Glycerol was crucial ingredient in the formation of the lamellar gel phase. The cleansing process of the cream soaps was also evaluated using the same diagrams. The structure of the continuous phase in cream soaps changed from lamellar gel to a micellar aqueous solution upon the addition of water. This structural change during the washing process is important in producing the foaming activity of acid soaps to wash away dirt or excess fats from the skin surface.

The substitution of milk fat with virgin coconut oil (VCO) was used to produce nutritious ice cream with pleasant coconut flavor and aroma. Three formulations were developed whereby formulation VCO4, VCO8 and VCO12 was substituted with 4%, 8% and 12% of VCO, respectively. The physicochemical properties of ice creams analyzed include overrun, meltdown, pH, titratable acidity, total solid, protein and fat content. The fatty acids profile of VCO formulated ice creams and their stabilities over 3 and 6 weeks storage were studied respectively using gas chromatography (GC). Qualitative descriptive analysis (QDA) and consumer affective test were performed among the trained and untrained panelists. Significant differences (p < 0.05) of overrun, pH, total solid, protein and fat content between ice cream formulations were observed except titratable acidity. Increased VCO content in ice cream formulations lowered the melting resistance of ice cream. For GC analysis, the major fatty acid identified was lauric acid. Upon storage time, the concentration of unsaturated fatty acid decreased but the concentration of saturated fatty acid increased. The result of QDA showed that formulation VCO4, VCO8 and VCO12 were significantly (p < 0.05) different in attributes of color, firmness and smoothness as compared to the control ice cream. Formulation VCO12 was highly accepted by panelists in terms of the acceptance level of appearance, aroma, texture, flavor and overall acceptability. Hence, it has a potential marketable value.

The study aimed to analyze the fatty acid content of Chlorella sp crude extract by using avocado oil solvent and determining the effectiveness of fatty acids Chlorella sp as the anti-aging cream The extraction of fatty acids from Chlorella sp using avocado oil as a solvent with three ratios were 1:10, 1:20 and 1:25 w/V. The highest lipid content was obtained at 1:20 w/V (gram microalgae: mL avocado oil) yielding 52.73%. Crude extracted were analysis by GC-MS and FTIR, and skin condition was determined by skin analyzer. The effectiveness test of Chlorella sp cream was applicated on the face of the panelists aged 20-60 years. From 10 panelists, the applied of Chlorella sp cream was 90% increased on the facial skin yielded moisture and oil content, 70% repair the skin structure. The composition of fatty acids Chlorella sp extract was palmitic acid, linoleic, oleic and stearate. Fatty acids crude extract of Chlorella sp can improve the effectiveness of anti-aging cream. The cream from Chlorella sp was more effective than the cream without containing microalgae. This is very promising because it is alternative to organic solvents i.e. green chemistry.

The primary objective of this study was to evaluate oxidation and firmness of butter and ice cream made with modified milkfat containing enhanced amounts of linoleic acid or oleic acid. The influence of the fatty acid profile of the HO milkfat relating to product properties as compared with the influence the fatty acid profile of the HL milkfat was the main focus of the research. Altering the degree of unsaturation in milkfat may affect melting characteristics and oxidation rates, leading to quality issues in dairy products. Three milkfat compositions (high-oleic, high-linoleic, and control) were obtained by modifying the diets of Holstein cows. Ice cream and butter were processed from milkfat obtained from cows in each dietary group. Butter and ice cream samples were analyzed to determine fatty acid profile and firmness. High-oleic milkfat resulted in a softer butter. Solid fat index of high-oleic and high-linoleic milkfat was lower than the control. Control ice cream mix had higher viscosity compared with high-oleic and high-linoleic, but firmness of all ice creams was similar when measured between -17 and -13 degrees C. Nutritional and textural properties of butter and ice cream can be improved by modifying the diets of cows.

The present study was designed to investigate the efficacy of a new formulation of alone, purified cannabidiol (CBD) (>98 %), the main non-psychotropic cannabinoid of Cannabis sativa, as a topical treatment in an experimental model of autoimmune encephalomyelitis (EAE), the most commonly used model for multiple sclerosis (MS). Particularly, we evaluated whether administration of a topical 1 % CBD-cream, given at the time of symptomatic disease onset, could affect the EAE progression and if this treatment could also recover paralysis of hind limbs, qualifying topical-CBD for the symptomatic treatment of MS. In order to have a preparation of 1 % of CBD-cream, pure CBD have been solubilized in propylene glycoland basic dense cream O/A. EAE was induced by immunization with myelin oligodendroglial glycoprotein peptide (MOG35-55) in C57BL/6 mice. After EAE onset, mice were allocated into several experimental groups (Naïve, EAE, EAE-1 % CBD-cream, EAE-vehicle cream, CTRL-1 % CBD-cream, CTRL-vehicle cream). Mice were observed daily for signs of EAE and weight loss. At the sacrifice of the animals, which occurred at the 28(th) day from EAE-induction, spinal cord and spleen tissues were collected in order to perform histological evaluation, immunohistochemistry and western blotting analysis. Achieved results surprisingly show that daily treatment with topical 1 % CBD-cream may exert neuroprotective effects against EAE, diminishing clinical disease score (mean of 5.0 in EAE mice vs 1.5 in EAE + CBD-cream), by recovering of paralysis of hind limbs and by ameliorating histological score typical of disease (lymphocytic infiltration and demyelination) in spinal cord tissues. Also, 1 % CBD-cream is able to counteract the EAE-induced damage reducing release of CD4 and CD8α T cells (spleen tissue localization was quantified about 10,69 % and 35,96 % of positive staining respectively in EAE mice) and expression of the main pro-inflammatory cytokines as well as several other direct or indirect markers of inflammation (p-selectin, IL-10, GFAP, Foxp3, TGF-β, IFN-γ), oxidative injury (Nitrotyrosine, iNOS, PARP) and apoptosis (Cleaved caspase 3). All these data suggest an interesting new profile of CBD that could lead to its introduction in the clinical management of MS and its associated symptoms at least in association with current conventional therapy.

To the best of our knowledge, till date no study comparing the efficacy and safety of terbinafine hydrochloride 1% cream and sertaconazole nitrate 2% cream has been done in localized tinea corporis and tinea cruris. This clinical trial was carried out to study and compare the efficacy of topical terbinafine hydrochloride 1% cream and sertaconazole nitrate 2% cream in localized tinea corporis and tinea cruris and to know the adverse effects of these antifungal creams. In this prospective, single blind, randomized control trial with two arms, patient were randomized into two groups Group A (treatment with terbinafine cream) and Group B (treatment with sertaconazole cream). A total of 38 patients were enrolled for the study, 20 patients in group A and 18 patients in group B. But five patients of group A and three patients of group B were lost for follow-ups. Therefore sample size was of 30 patients with 15 patients in group A and group B each. Patients in group A and B were treated with twice daily topical 1% terbinafine hydrochloride and 2% sertaconazole nitrate cream respectively for a total duration of three weeks. Clinical improvement in signs and symptoms of each clinical parameter, namely itching, erythema, papules, pustules, vesicles, and scaling were graded weekly and clinical cure was assessed. KOH mount and culture was done weekly up to 3 weeks to access mycological cure. Fungal culture was done on Sabouraud's dextrose agar with chloramphenicol and cycloheximide. Statistical analysis was done using students paired and unpaired t-tests from the data obtained. Comparison between Group A and Group B for complete cure (clinical and mycological) showed that at the end of 3 weeks both terbinafine and sertaconazole groups had 100% complete cure. When the two groups were compared for complete cure, at the end of 1(st) and 2(nd) week, statistically non-significant results were observed (P = 0.461 and P = 0.679 respectively). However, at the end of 2(nd) week, complete cure rate for terbinafine was 80% as compared to 73.35% for sertaconazole with no statistical significance. In both Group A and Group B, clinically significant local side effects like erythema, swelling, stinging sensation, or increased itching were not noticed. A majority of our patients in both the group showed Trichophyton rubrum followed by Trichophyton mentagrophytes growth on culture. In Group A, 11 patients showed growth of T. rubrum, 2 patients showed growth of T. mentagrophytes, and 1 patient had only KOH test positive. In Group B, 10 patients revealed growth of T. rubrum, followed by growth of T. mentagrophytes in 3 and Microsporum canis in 2 patients. The therapeutic response is more or less same in infection with different species. The newer fungistatic drug sertaconazole nitrate 2% cream was as effective as terbinafine hydrochloride 1% cream which is one of the fungicidal drugs, though terbinafine hydrochloride 1% cream has higher rates of complete cure at the end of 2 weeks as compared to sertaconazole nitrate 2% cream. Both the drugs showed good tolerability with no adverse effects.

Repellents are commonly used personal protection measures to avoid mosquito bites. In the present study, Advanced Odomos cream (12% N, N-diethyl-benzamide) was tested for its efficacy against mosquitoes in comparison to DEET (N,N-diethyl-3-methyl benzamide). Bioassays were conducted to assess the repellency of Advanced Odomos and DEET creams against Anopheles stephensi and Aedes aegypti. Their efficacy was tested on human volunteers applied with different concentrations of test creams ranging from 1 to 12 mg/cm 2 and by exposing them to mosquitoes at hourly intervals. Field evaluation was also carried out to test the duration of protection of the test creams against Anopheles and Aedes mosquitoes during whole night and day time collections, respectively on human volunteers. Mosquito collections were done using torch light and aspirator. Complete (100%) protection was achieved at 10 mg/cm 2 cream formulation of Advanced Odomos (1.2 mg a.i/cm 2 ) dose against An. stephensi and 12 mg/cm 2 (1.44 mg a.i./cm 2 ) against Ae. aegypti on human baits. There was no statistically significant differences in per cent protection against mosquito bites between Advanced Odomos and DEET cream (P>0.05) in respective doses. Complete protection up to 11 h was observed against Anopheles mosquitoes during whole night collections and up to 6 h against Ae. aegypti in day time collections. No adverse reactions such as itching, irritation, vomiting, nausea, etc. were reported by the volunteers. Advanced Odomos cream applied at 10 mg/cm 2 concentration provided 100% protection from Anopheles mosquitoes up to 11 h whereas about 6 h protection was recorded against Ae. aegypti. The laboratory and field trials indicate that for longer protection against Anopheles mosquitoes 10 mg/cm 2 will be appropriate and in case of Ae. aegypti more than 10 mg/cm 2 application is required for complete protection. In conclusion, the Advanced Odomos cream was comparable to the known repellent cream DEET for prolonged protection against malaria and dengue vectors.

A Natural Cream-to-Powder Formulation Developed for the Prevention of Diaper Dermatitis in Diaper-Wearing Infants and Children: Barrier Property and In-Use Tolerance Studies.

Gunt, Hemali B; Levy, Stanley B; Lutrario, Celeste A

2018-05-01

Diaper dermatitis is a common condition that develops in the diaper area due to factors such as elevated moisture, increased skin surface pH, and exposure to irritants from urine and feces. These factors suggest interventions to prevent or treat diaper dermatitis such as exposing the skin to air, frequent diaper changes, and thorough cleansing of the diaper area. Barrier creams and powders also have a role in preventing and treating diaper dermatitis. We developed a cream-to-powder product with a formula based on corn starch and other natural ingredients for use in the diaper area. Dye exclusion study: The barrier properties of the cream-to-powder product were assessed using a dye exclusion protocol. Skin color at treated and untreated forearm sites was measured at baseline and after exposure to crystal violet stain. The cream-to-powder product's ability to inhibit the water-soluble dye from reaching the skin was judged by comparing color changes at the treated and untreated sites. Tolerance-in-use study: The safety of the cream-to-powder product was assessed in a four-week tolerance-in-use study conducted in a group of 52 diaper-wearing infants and toddlers. Subjects' parents/guardians applied the cream-to-powder product at each diaper change. A pediatrician judged safety endpoints of erythema, dryness, and edema in the diaper area at baseline and at study end. Parents/guardians also completed a questionnaire at study end. These studies have complied with Good Clinical Practices (GCP/ICH). The cream-to-powder product prevented about 70% of the test dye from reaching the skin surface, demonstrating its ability to supplement the skin barrier. The tolerance-in-use study showed no statistically significant changes in any of the safety endpoints; there were no adverse events. Parents/guardians responses to the cream-to-powder product were overwhelmingly positive. Taken together, these results support that the cream-to-powder formulation is safe and effective for helping to prevent diaper dermatitis. J Drugs Dermatol. 2018;17(5):566-570.

This study aimed to determine the efficacy and safety of fluocinolone acetonide, hydroquinone, and tretinoin (FAHT) cream for the treatment of moderate and severe facial melasma. The primary objective was assessment of clinical efficacy, instrumental measured efficacy, and integral therapeutic efficacy at the end of weeks 4 and 8. A total of 233 subjects were randomly allocated (1:1 ratio) to receive topically administered FAHT cream (n = 117) or placebo (n = 116) once nightly for 8 weeks. Observed side effects were documented throughout. In the per protocol set (PPS; those subjects who met all requirements of the protocol), the integral therapeutic efficacy rate of FAHT cream on moderate and severe melasma was 68.57% (vs. placebo, 0.94%), the clinical effective rate of FAHT cream was 74.29 % (vs. placebo, 0.94%), and the instrumental measure efficacy of FAHT cream was 71.43% (vs. placebo, 6.60%). The difference in efficacy between the two groups was statistically significant (p < 0.001). In the full analysis set (FAS; the PPS and those subjects who were lost to follow-up but received at least one study treatment), the integral therapeutic efficacy rate of FAHT cream was 64.60% (vs. placebo, 0.88%), the clinical effective rate of FAHT cream was 69.91% (vs. placebo, 0.88%), and the instrumental measure efficacy of FAHT cream was 69.03 % (vs. placebo, 7.08%). The difference in efficacy between the two groups was statistically significant (p < 0.001). Of 113 subjects in the FAHT group, 34 (30.1%) reported adverse effects. Most of the pathological adverse effects were mild and resolved with either continuous treatment or discontinuation. Of 113 subjects in the placebo group, three (2.6%) reported mild adverse effects. No severe adverse effects or other abnormal clinical results were associated with the study treatment. FAHT cream is efficacious, well tolerated, and has a high margin of safety for the treatment of moderate and severe melasma in the Chinese population.

The purpose of this study was to examine flavor binding of high hydrostatic pressure (HHP)-treated whey protein concentrate (WPC) in a real food system. Fresh Washington State University (WSU, Pullman) WPC, produced by ultrafiltration of separated Cheddar cheese whey, was treated at 300 MPa for 15 min. Commercial WPC 35 powder was reconstituted to equivalent total solids as WSU WPC (8.23%). Six batches of low-fat ice cream were produced: A) HHP-treated WSU WPC without diacetyl; B) and E) WSU WPC with 2 mg/L of diacetyl added before HHP; C) WSU WPC with 2 mg/L of diacetyl added after HHP; D) untreated WSU WPC with 2 mg/L of diacetyl; and F) untreated commercial WPC 35 with 2 mg/L of diacetyl. The solution of WSU WPC or commercial WPC 35 contributed 10% to the mix formulation. Ice creams were produced by using standard ice cream ingredients and processes. Low-fat ice creams containing HHP-treated WSU WPC and untreated WSU WPC were analyzed using headspace-solid phase microextraction-gas chromatography. Sensory evaluation by balanced reference duo-trio test was carried out using 50 untrained panelists in 2 sessions on 2 different days. The headspace-solid phase microextraction-gas chromatography analysis revealed that ice cream containing HHP-treated WSU WPC had almost 3 times the concentration of diacetyl compared with ice cream containing untreated WSU WPC at d 1 of storage. However, diacetyl was not detected in ice creams after 14 d of storage. Eighty percent of panelists were able to distinguish between low-fat ice creams containing untreated WSU WPC with and without diacetyl, confirming panelists' ability to detect diacetyl. However, panelists were not able to distinguish between low-fat ice creams containing untreated and HHP-treated WSU WPC with diacetyl. These results show that WPC diacetyl-binding properties were not enhanced by 300-MPa HHP treatment for 15 min, indicating that HHP may not be suitable for such applications.

WenTong HuoXue Cream (WTHX-Cream) has been shown to effectively alleviate clinical symptoms of diabetic peripheral neuropathy (DPN). This study investigated the gene and protein expression of the pain-related molecule PLC-β3 in the dorsal root ganglion (DRG) of DPN rats. 88 specific pathogen-free male Wistar rats were randomly divided into placebo (10 rats) and DPN model (78 rats) groups, and the 78 model rats were used to establish the DPN model by intraperitoneal injection of streptozotocin and were then fed a high-fat diet for 8 weeks. These rats were randomly divided into the model group, the high-, medium-, and low-dose WTHX-Cream + metformin groups, the metformin group, the capsaicin cream group, and the capsaicin cream + metformin group. After 4 weeks of continuous drug administration, the blood glucose, body weight, behavioral indexes, and sciatic nerve conduction velocity were measured. The pathological structure of the DRG and the sciatic nerve were observed. PLC-β3 mRNA and protein levels in the DRG of rats were measured. Compared with the model group, the high-dose WTHX-Cream group showed increased sciatic nerve conduction velocity, improved sciatic nerve morphological changes, and increased expression of PLC-β3 mRNA and protein in the DRG. This study showed that WTHX-Cream improves hyperalgesia symptoms of DPN by inhibiting the reduction of PLC-β3 mRNA and protein expression in the diabetic DRG of DPN rats. PMID:29599806

To determine the effect of feeding frequency on appetite in normal weight (NW) and obese (OB) prepubertal children, we carried out a prospective, randomized interventional study of 18 NW and 17 OB children ages 6–10. Children received three or five feedings in random order on separate days. Total calories, carbohydrate, protein, and fat composition on each day were equal. Two hours following the last feeding, children were offered ice cream ad lib. The major outcome variable was kilocalories ice cream consumed. A visual analog scale to assess fullness was also administered before consumption of ice cream. We observed that OB children consumed 73.0 ± 37.4 kcal more after five feedings than after three feedings whereas the NW children consumed 47.1 ± 27.8 kcal less. There was significant interaction between meal pattern and weight group indicating that this change in ice cream consumption differed significantly between groups (P = 0.014 by two-factor analysis). Ice cream intake/kg was less in OB compared to NW subjects (P = 0.012). Fullness ratings before ice cream did not differ by meal pattern or weight group. However, pre-ice cream fullness predicted ice cream intake in NW but not OB children. In summary, OB and NW children differed in appetite response to meal frequency. Our data suggest that: (i) satiety in OB children is related more to proximity of calories (larger supper) than to antecedent distribution of calories and; (ii) NW children may be more prone to restrict intake based on subjective fullness.

Atopic dermatitis is a chronic, pruritic inflammatory skin disease that adversely affects quality of life. The current study evaluates the efficacy of a shower cream and a lotion, each with skin-identical lipids and emollients, in the treatment of atopic dry skin of subjects with a history of atopic condition. In all, 40 healthy females with clinically dry skin on the lower legs were enrolled in the study and underwent 4 weeks of daily use of the shower cream and 2 additional weeks of both the shower cream and the body lotion. Subjects were evaluated at day 0, week 4, and week 6. Skin barrier function was assessed by Tewameter ® , skin hydration by Corneometer ® , smoothness and desquamation by Visioscan ® , and stratum corneum architecture by reflectance confocal microscopy (RCM). The investigator assessed the degree of dryness, roughness, redness, cracks, tingling and itch, and subjective self-assessment evaluated the perception of skin soothing, smoothness, and softness. Skin barrier function and skin moisture maintenance were significantly improved using the shower cream. The lotion with physiological lipids, together with the shower cream, also improved skin barrier function and moisture. Both the shower cream and the body lotion reduced clinical dryness, roughness, redness, cracks, tingling and itch, according to the dermatologist, and increased soothing, smoothness, and softness, according to the subjects of the study. The combination of a shower cream and a lotion with physiological lipids efficiently restores skin barrier function and increases skin hydration, becoming an effective skin-care option for patients with atopic dry skin. © 2018 Wiley Periodicals, Inc.

Papulopustular rosacea (PPR) is characterized by facial erythema and inflammatory lesions believed to be primarily caused by dysregulation of the innate immune system. More recent evidence also suggests that Demodex folliculorum mites may contribute to the etiology of PPR. Ivermectin (IVM) 1% cream is a novel topical treatment developed to treat PPR. Two phase 3 trials have demonstrated that IVM 1% cream was significantly better than vehicle at investigator global assessment (IGA) success rate and lesion reductions and that it was safe and well tolerated. Two 40-week extension studies of those trials were conducted to assess the long-term safety of IVM 1% cream vs azelaic acid (AzA) 15% gel. Subjects originally treated with IVM 1% continued on IVM 1% and those originally treated with vehicle switched to AzA 15% gel. IVM 1% cream was safe throughout the study with a lower incidence of related adverse events (AEs) compared to AzA 15% gel. No subjects in the IVM 1% cream group discontinued either study due to a related AE. IVM 1% also continued to be efficacious during the 40-week extension studies as the percentage of subjects with IGA scores of clear or almost clear was higher at the end of the study compared to baseline. The results of these 40-week extension studies support the use of IVM 1% cream as a long-term therapy for PPR as IVM 1% cream was shown to be safe and effective for up to 52 weeks of total treatment.

Almost everybody likes ice cream, so it can provide an excellent vehicle for discussing and demonstrating a variety of physical phenomena, such as Newton's law of cooling, Boyle's law and the relationship between microstructure and macroscopic properties (e.g. Young's modulus). Furthermore, a demonstration of freezing point depression can be used to make ice cream in the classroom!

Effect of Encapsulation on Viability of Bifidobacterium longum CFR815j and Physiochemical Properties of Ice Cream.

PubMed

Kataria, Ankita; Achi, Sajan C; Halami, Prakash M

2018-06-01

The health beneficial attributes of bifidobacteria and its safe association with the host gut has increased its significance as a probiotic. However delivering probiotic bifidobacteria with Minimum Biological Value (MBV) through product has always been a challenge. In the present study, an attempt was made to maintain the viability of native isolate of Bifidobacterium longum CFR 815j and deliver through ice-cream. B. longum CFR815j was microencapsulated in alginate starch capsules by emulsification followed by evaluation of bead stability in simulated gastrointestinal conditions. After incorporation in ice-cream, the effect on chemical properties, sensory parameters and meltdown characteristics of the product were also evaluated. Survival studies of B. longum revealed higher counts than 10 7 in the product which is essential for probiotic bacteria to exhibit beneficial effect. Further, all the properties of this ice-cream were comparable to the regular ice-cream. Our studies conclude that encapsulation was able to maintain the requisite MBV of bifidobacteria in ice-cream without affecting the sensory characteristics.

Effect of casein and inulin addition on physico-chemical characteristics of low fat camel dairy cream.

2018-05-21

The effect of the addition of the camel casein fraction on some physico-chemical properties of low fat camel milk cream was studied. Oil-in-water emulsions, 25, 30, and 35 (w/w) fat, were prepared using inulin, camel skim milk, milk fat and variable percentages of casein (1, 2, and 3% w/w). The droplet size, ζ-potential, surface protein concentration, viscosity and surface tension of low fat dairy creams was measured. Cream containing 2% (w/w) casein had better stability. The modifications in physico-chemical properties appeared to be driven by changes in particle size distribution caused by droplet aggregation. The cream containing 2% casein leads to a gradual decrease in droplet size, as the particle size decreased, apparent viscosity increased. When casein concentration increased, ζ-potential decreased due to combination of c terminal (negative charge) with the surface of fat particles but steric repulsion improved textural properties. Cream with 30% fat and 2% casein had the best result. Copyright © 2018 Elsevier B.V. All rights reserved.

Outbreak of verocytotoxin-producing E. coli O145 and O26 infections associated with the consumption of ice cream produced at a farm, Belgium, 2007.

In October 2007, an outbreak of verocytotoxin-producing Escherichia coli (VTEC) O145 and E. coli O26 occurred among consumers of ice cream produced and sold in September 2007 at a farm in the province of Antwerp (Belgium). The ice cream was consumed at two birthday parties and also eaten at the farm. Five children, aged between two and 11 years, developed haemolytic uraemic syndrome (HUS), and seven other co-exposed persons contracted severe diarrhoea. In three of the five HUS cases VTEC O145 infections were laboratory confirmed, one in association with VTEC O26. Identical isolates of E. coli O145 and O26 were detected with PCR and PFGE in faecal samples of patients and in ice cream leftovers from one of the birthday parties, in faecal samples taken from calves, and in samples of soiled straw from the farm at which the ice cream was produced. Ice cream was made from pasteurised milk and most likely contaminated by one of food handlers.

In this study, sixty-two (62) skin-lightening creams and soaps were analysed for total mercury and hydroquinone levels. Total mercury was determined by the Cold Vapour Atomic Absorption Spectrophotometry using an automatic mercury analyser and hydroquinone by High Performance Liquid Chromatography. The mean concentration of total mercury in skin toning creams and cosmetic soaps were 0.098 ± 0.082 and 0.152 ± 0.126 μg/g, respectively. The mean concentration of hydroquinone was 0.243 ± 0.385 and 0.035 ± 0.021 % in skin toning creams and cosmetic soaps, respectively. All the creams and soaps analysed had mercury and hydroquinone levels below the US Food and Drug Administration's acceptable limit of 1 μg/g and 2 %, respectively. The low levels of mercury and hydroquinone in the creams and soaps analysed in this study therefore do not pose any potential risk to consumers who are mostly women in Ghana.

In the highly competitive market, it is increasingly hard for ice cream stores to develop creative marketing strategies to retain existing customers and attract new ones. This study applies the means-end chain approach to identify the customer value, consequences, and attributes of ice cream and to suggest useful information for ice cream sellers to develop differential marketing strategies across various consumption situations (i.e. on a date, gathering with friends, craving for ice cream). This study conducted one-on-one in-depth interviews with participants. The interview content was subsequently analyzed and coded to produce an implication matrix and a hierarchical value map, which was further used to determine customers' value perceptions. The results indicate the terminal values of the highest strength comprised economy, pleasure, and efficiency. Pleasure was emphasized among consumers who were on a date or gathering with friends, whereas satisfaction was emphasized among consumers who craved ice cream. Based on the results, the study also provides suggestions to the industry and future researchers.

An Evidential Reasoning-Based CREAM to Human Reliability Analysis in Maritime Accident Process.

2017-10-01

This article proposes a modified cognitive reliability and error analysis method (CREAM) for estimating the human error probability in the maritime accident process on the basis of an evidential reasoning approach. This modified CREAM is developed to precisely quantify the linguistic variables of the common performance conditions and to overcome the problem of ignoring the uncertainty caused by incomplete information in the existing CREAM models. Moreover, this article views maritime accident development from the sequential perspective, where a scenario- and barrier-based framework is proposed to describe the maritime accident process. This evidential reasoning-based CREAM approach together with the proposed accident development framework are applied to human reliability analysis of a ship capsizing accident. It will facilitate subjective human reliability analysis in different engineering systems where uncertainty exists in practice. © 2017 Society for Risk Analysis.

Antiaging efficacy of melatonin-based day and night creams: a randomized, split-face, assessor-blinded proof-of-concept trial.

Skin is a complete and independent melatoninergic system. At the skin level, melatonin (Mel) acts as a relevant antioxidant and cytoprotective substance. Topical application of Mel is considered meaningful, since it can easily penetrate the stratum corneum. Exogenous Mel can be expected to represent a potent antioxidative defense system against skin aging mechanisms. Day and night creams containing Mel, carried in lipospheres (Melatosphere™), have been developed (Nutriage SPF 30 day cream and Nutriage night cream). The aim of this study was to evaluate the efficacy of a Mel-based cream as antiaging treatment. In a randomized, split-face, assessor-blinded, prospective 3-month study, 22 women (mean age 55 years) with moderate-severe skin aging were enrolled (clinical trial registration number: NCT03276897). Study products were applied in the morning (Nutriage day cream) and evening (Nutriage night cream) on the right or left side of the face. Primary outcomes were: 1) clinical evaluation of wrinkles' grade (crow's feet and nasolabial folds), surface microrelief, skin tonicity (resistance to pinching and traction, recovery after pinching) and skin dryness and 2) instrumental evaluation of skin roughness and 3D photographic documentation (Vectra H1 images system). Assessments of both clinical and instrumental evaluations were performed at baseline and after 1, 2 and 3 months of treatment by an investigator unaware of treatment allocation. All the subjects completed the study. Crow's feet was reduced significantly ( p =0.05) by -15% with the creams in comparison with the non-treated side after 3 months. At the end of the study, surface microrelief (-26.5%), skin profilometry (-13%), skin tonicity (+30%) and skin dryness (-59.5%) significantly improved with active treatment. Both products were well tolerated. In women with skin aging, Mel-based creams improved significantly skin tonicity and skin hydration with a significant reduction in skin roughness, supporting the skin antiaging effect of this molecule applied topically.

Abstract Objective: Infants may benefit from early nutritional intervention to decrease hospital stay. To evaluate the effects of adding a human milk (HM)-derived cream (Cream) product to a standard feeding regimen in preterm infants. Materials and Methods: In a prospective multicenter randomized study, infants with birth weights 750–1,250 g were assigned to a Control or Cream group. The Control group received a standard feeding regimen consisting of mother's own milk or donor HM with donor HM-derived fortifier. The Cream group received the standard feeding regimen along with an additional HM-derived cream supplement when the HM they received was <20 kcal/oz. Primary outcomes of this secondary analysis included comorbidities, length of stay (LOS), and postmenstrual age (PMA) at discharge. Results: We enrolled 75 infants (Control n = 37, Cream n = 38) with gestational age 27.7 ± 1.8 weeks and birth weight 973 ± 145 g (mean ± SD). After adjusting for gestational age, birth weight, and presence of bronchopulmonary dysplasia (BPD), the Cream group had a decreased PMA at discharge (39.9 ± 4.8 versus 38.2 ± 2.7 weeks, p = 0.03) and LOS (86 ± 39 versus 74 ± 22 days, p = 0.05). For 21 infants with BPD, these values trended toward significance for PMA at discharge (44.2 ± 6.1 versus 41.3 ± 2.7 weeks, p = 0.08) and LOS (121 ± 49 versus 104 ± 23 days, p = 0.08). Conclusions: Very preterm infants who received an HM-derived cream supplement were discharged earlier. Infants with BPD may have benefited the most. PMID:26982282

Background A non-steroidal, anti-inflammatory moisturizing cream containing rhamnosoft, ceramides, and L-isoleucine (ILE) (pro-AMP cream) has been recently developed for the specific treatment of atopic eczema (AE) of the face. In this trial, we evaluated the clinical efficacy and tolerability of pro-AMP cream in the treatment of facial AE in children in comparison with an emollient cream. Methods In a randomized, prospective, assessor-blinded, parallel groups (2:1) controlled trial, 107 children (72 allocated to pro-AMP cream and 35 allocated to control group) with mild-to-moderate chronic AE of the face were enrolled. Treatments were applied twice daily for a 6-week period. Facial Eczema Severity Score (ESS) was evaluated at baseline, week 3, and week 6, by an assessor unaware of treatment allocation. Investigator's Global Assessment (IGA) score was assessed at week 3 and at week 6. Tolerability was evaluated at week 3 and at week 6 using a 4-point score (from 0: low tolerability to 3: very good tolerability). Results At baseline ESS, mean (SD) was 6.1 (2.4) in the pro-AMP cream group and 5.3 (3) in the control group. In the pro-AMP group, in comparison with baseline, ESS was significantly reduced to 2.5 (−59%) after 3 wks and to 1.0 (−84%) at week 6 (p = 0.0001). In the control group, ESS was reduced to 3 (−42%) at week 2 and to 2.6 (−50%) at week 6. At week 6, ESS in pro-AMP cream was significantly lower than the control group (1.0 vs. 2.6; p = 0.001). Both products were well tolerated. Conclusion Pro-AMP cream has shown to be effective in the treatment of mild-to-moderate chronic lesion of AE of the face. Clinical efficacy was greater in comparison with an emollient cream. (Clinical trial Registry: NTR4084). PMID:24750568

We report what we think is the first treatment of oral dysplasia with 5% imiquimod cream. A 60-year-old man presented with varying degrees of dysplasia on the soft palate. A cover plate was fabricated and the patient was prescribed 5% imiquimod cream, a topical imunomodulator, for six weeks. The lesion improved and histological examination of an incisional biopsy found no features of dysplasia. This case highlights the efficacy of imiquimod cream in the treatment of dysplasia, and the need for development of a preparation suitable for the oral mucosa. Copyright © 2016.

Effect of Porcine Collagen Peptides on the Rheological and Sensory Properties of Ice Cream

PubMed Central

2015-01-01

The effects of low molecular-weight collagen peptides derived from porcine skin were investigated on the physicochemical and sensorial properties of chocolate ice cream. Collagen peptides less than 1 kDa in weight were obtained by sub-critical water hydrolysis at a temperature of 300℃ and a pressure of 80 bar. Ice cream was then prepared with gelatin powder and porcine skin hydrolysate (PSH) stabilizers mixed at seven different ratios (for a total of 0.5 wt%). There was no significant difference in color between the resulting ice cream mixtures. The increase in apparent viscosity and shear thinning of the ice cream was more moderate with PSH added than with gelatin. Moreover, the samples containing more than 0.2 wt% PSH had enhanced melting resistance, while the mixture with 0.2 wt% PSH had the lowest storage modulus at -20℃ and the second highest loss modulus at 10℃, indicating that this combination of hydrocolloids leads to relatively softer and creamier chocolate ice cream. Among the seven types of ice creams tested, the mixture with 0.2 wt% PSH and 0.3 wt% gelatin had the best physicochemical properties. However, in sensory evaluations, the samples containing PSH had lower chocolate flavor scores and higher off-flavor scores than the sample prepared with just 0.5 wt% gelatin due to the strong off-flavor of PSH.

Hyperforin is well-known for its anti-inflammatory, anti-tumor, anti-bacterial, and antioxidant properties. The application of a hyperforin-rich verum cream could strengthen the skin barrier function by reducing radical formation and stabilizing stratum corneum lipids. Here, it was investigated whether topical treatment with a hyperforin-rich cream increases the radical protection of the skin during VIS/NIR irradiation. Skin lipid profile was investigated applying HPTLC on skin lipid extracts. Furthermore, the absorption- and scattering coefficients, which influence radical formation, were determined. 11 volunteers were included in this study. After a single cream application, VIS/NIR-induced radical formation could be completely inhibited by both verum and placebo showing an immediate protection. After an application period of 4weeks, radical formation could be significantly reduced by 45% following placebo application and 78% after verum application showing a long-term protection. Furthermore, the skin lipids in both verum and placebo groups increased directly after a single cream application but only significantly for ceramide [AP], [NP1], and squalene. After long-term cream application, concentration of cholesterol and the ceramides increased, but no significance was observed. These results indicate that regular application of the hyperforin-rich cream can reduce radical formation and can stabilize skin lipids, which are responsible for the barrier function.

Fish protein powder is a functional ingredient that can be used for enhancing the nutritional value of food products. In this study the effect of fortification with different levels of fish protein powder (FP) on chemical properties and sensory quality of Persian ice cream with 0, 30 and 50 g kg(-1) FP during storage at - 18 °C for 4 months was investigated. Ice creams fortified with 50 and 30 g kg(-1) FP had significantly higher protein and solid-non-fat content than ice cream with 0% FP or 83, 69 and 51 g kg(-1) protein and 215, 204 and 181 g kg(-1) solid non-fat, respectively. All products had the same levels of fat, lactose, acidity and pH. They had similar sensory quality after production except for colour, but sensory properties of fortified samples changed significantly after 2 months of storage. Colour faded, cohesiveness decreased, sandiness/coarseness increased, sweetness decreased and fish flavour and off-odour increased. The control ice cream scored highest for additives odour and flavour. Development of ice cream fortified with fish protein powder could be an effective way to enhance nutritional and functional value of ice cream. But studies on storage stability, consumers' acceptance and attitudes are recommended if companies are planning to do so. Copyright © 2011 Society of Chemical Industry.

High consumption of bakery products such as cream-filled pastries may cause serious health risks and food poisoning to humans. Therefore, investigation of the microbial and chemical qualities of bakery products containing cream is necessary. The purpose of the present study was to investigate the chemical qualities and microbial contaminations of cream-filled pastries collected from confectioneries located in six cities in Chaharmahal Va Bakhtiari province (Southwestern Iran). Microbial tests and chemical characteristics (fat and acidity level) were done on 228 cream-filled pastries samples that were collected randomly from various confectioneries. After microbial tests, it was found that 33.33% of all samples were contaminated by microbial agents. The microbial tests showed that Shahrekord (10.09%) and Broujen (9.21%) cities had high levels of contamination and in Koohrang (1.31%) it was low compared with the other four cities. High contamination of coliforms (61.84%), staphylococci (48.68%), and yeast (27.63%) were observed in almost all samples. The chemical analysis showed maximum amounts of fat content and titratable acidity in cream-filled pastry samples obtained from Lordegan and Shahrekord cities, respectively. The findings of the present work demonstrated that the microbial contamination and chemical quality of cream-filled pastries produced in confectionaries of Chaharmahal Va Bakhtiari province were not in acceptable ranges. These problems may be related to fecal contamination of cream samples or lack of hygiene by handlers and it is necessary to observe the standards of hygiene and to develop safe food handling techniques and aseptic pastry manufacturing systems in some confectioneries of Chaharmahal Va Bakhtiari province.

A review of modern instrumental techniques for measurements of ice cream characteristics.

Bahram-Parvar, Maryam

2015-12-01

There is an increasing demand of the food industries and research institutes to have means of measurement allowing the characterization of foods. Ice cream, as a complex food system, consists of a frozen matrix containing air bubbles, fat globules, ice crystals, and an unfrozen serum phase. Some deficiencies in conventional methods for testing this product encourage the use of alternative techniques such as rheometry, spectroscopy, X-ray, electro-analytical techniques, ultrasound, and laser. Despite the development of novel instrumental applications in food science, use of some of them in ice cream testing is few, but has shown promising results. Developing the novel methods should increase our understanding of characteristics of ice cream and may allow online testing of the product. This review article discusses the potential of destructive and non-destructive methodologies in determining the quality and characteristics of ice cream and similar products. Copyright © 2015.

We report on the antimicrobial activity of a cream formulation of silver nanoparticles (AgNPs), biosynthesized using Withania somnifera extract. Aqueous extracts of leaves promoted efficient green synthesis of AgNPs compared to fruits and root extracts of W. somnifera. Biosynthesized AgNPs were characterized for their size and shape by physical-chemical techniques such as UV-visible spectroscopy, laser Doppler anemometry, transmission electron microscopy, scanning electron microscopy, atomic force microscopy, X-ray diffraction, and X-ray energy dispersive spectroscopy. After confirming the antimicrobial potential of AgNPs, they were incorporated into a cream. Cream formulations of AgNPs and AgNO3 were prepared and compared for their antimicrobial activity against human pathogens (Staphylococcus aureus, Pseudomonas aeruginosa, Proteus vulgaris, Escherichia coli, and Candida albicans) and a plant pathogen (Agrobacterium tumefaciens). Our results show that AgNP creams possess significantly higher antimicrobial activity against the tested organisms. PMID:26445537

The effect of the color red on consuming food does not depend on achromatic (Michelson) contrast and extends to rubbing cream on the skin.

Recent literature suggests that individuals may consume less food when this is served on red plates. We explored this intriguing effect in three experiments. Independent groups of participants were presented with constant amounts of popcorns, chocolate chips, or moisturizing cream, on red, blue, or white plates. They were asked to sample the foods (by tasting them) or the cream (by rubbing it on the hand and forearm) as they wished and to complete mock "sensory analysis" questionnaires. Results confirmed that red plates reduce taste-related consumption and extended this effect to the touch-related consumption of moisturizing cream. Suggesting that the effect was not due to a decrease in the consciously experienced appeal of products on red plates, overall appreciation of the foods or cream did not differ according to plate color. After careful photometric measures of the materials used for each food-plate pairing, we determined that food and cream consumption was not predicted by Michelson (achromatic) contrast. Although the origin of the intriguing effect of the color red on consumption remains unclear, our results may prove useful to future potential explanations. Copyright © 2013 Elsevier Ltd.

2018-05-01

Microencapsulated flaxseed oil powder (MFOP) was supplemented for the fortification of α-linolenic acid (ALA, ω-3 fatty acid) in ice cream. Processing parameters were optimized in terms of the stage of homogenization of ice-cream mix, level of fortification (3, 4 and 5%) and flavors (vanilla, butter scotch and strawberry). Data revealed that free fatty acids increased significantly during first 15 days in all the samples and then remained constant. Peroxide value and thiobarbituric acid value first increased up to 30 and 45 days, respectively; and then decreased followed by a gradual increase up to 120 days. Fatty acids profile showed 18.74-21.38% decrease in ALA content in fortified ice creams after 120 days. A serving of 100 g of freshly prepared functional ice cream was able to meet ~ 45% of the RDA (1.4 g ALA/day), which reduced to 35.37-36.56% on the end of storage i.e. 120 days. Overall, it can be concluded that MFOP was oxidative stable in ice-cream throughout the storage, which could be fortified successfully at 4% (w/w) level.

The anti-Malassezia furfur activity in vitro and in experimental dermatitis of six imidazole antifungal agents: bifonazole, clotrimazole, flutrimazole, ketoconazole, miconazole and sertaconazole.

Bifonazole, clotrimazole, flutrimazole, ketoconazole, miconazole and sertaconazole were tested for their activity against 23 isolates of Malassezia furfur by agar dilution in vitro. Topical formulations of the same agents were evaluated for efficacy against M. furfur skin infections in guinea pigs in vivo. The most potent inhibitor in vitro was ketoconazole (geometric mean minimum inhibitory concentration 0.51 microgram ml-1), followed by bifonazole (8.1 micrograms ml-1), then miconazole (14 micrograms ml-1), clotrimazole (15 micrograms ml-1) and flutrimazole (16 micrograms ml-1), with sertaconazole the least active (52 micrograms ml-1). In animal experiments involving three consecutive days of topical treatments, bifonazole 1% cream, clotrimazole 1% cream, flutrimazole 1% and 2% creams, ketoconazole 2% cream and shampoo and miconazole 2% cream all reduced M. furfur dermatitis lesion severity below that of untreated control animals; however, sertaconazole 2% gel and cream showed no reduction in lesion severity below control. The results confirm that ketoconazole is a more potent inhibitor of M. furfur in vitro than other topical antifungal agents of its class and suggest that sertaconazole is the least effective of such agents among those tested.

Retinoids and hydroxy acids have been widely used due to their effects in the regulation of growth and in the differentiation of epithelial cells. However, besides their similar indication, they have different mechanisms of action and thus they may have different effects on the skin; in addition, since the topical formulation efficiency depends on vehicle characteristics, the ingredients of the formulation could alter their effects. Thus the objective of this study was to compare the effects of retinoic acid (RA) and glycolic acid (GA) treatment on the hairless mouse epidermis thickness and horny layer renewal when added in gel, gel cream, or cream formulations. For this, gel, gel cream, and cream formulations (with or without 6% GA or 0.05% RA) were applied in the dorsum of hairless mice, once a day for seven days. After that, the skin was analyzed by histopathologic, morphometric, and stereologic techniques. It was observed that the effects of RA occurred independently from the vehicle, while GA had better results when added in the gel cream and cream. Retinoic acid was more effective when compared to glycolic acid, mainly in the cell renewal and the exfoliation process because it decreased the horny layer thickness. PMID:25632398

Effect of milk fat, cocoa butter, and whey protein fat replacers on the sensory properties of lowfat and nonfat chocolate ice cream.

2000-10-01

Lowfat and nonfat chocolate ice creams were made with 2.5% of milk fat, cocoa butter, or one of two whey protein-based fat replacers, Dairy Lo or Simplesse. Polydextrose was added as required so that all formulations contained the same amount of total solids. Ice cream was stored at a control temperature of-30 degrees C. Hardness, viscosity, and melting rate were measured by physical methods. Trained panelists conducted descriptive sensory analyses of the samples at 0, 6, and 12 wk. Attribute ratings were analyzed by analysis o variance with least significant difference mean separation and orthogonal contrasting. Data were also analyzed by multivariate analysis of variance with canonical variate analysis. Consumer acceptance (n = 50) did not differ among the fresh ice creams (wk 0). Ice cream containing milk fat had less intense cocoa flavor and was more resistant to textural changes over time compared with the other ice creams. Simplesse was more similar to milk fat than was Dairy Lo in its effect on brown color, cocoa flavor, cocoa character, and textural stability but was less similar in terms of thickness and mouthcoating.

To compare the levels of mutans streptococci and lactobacilli in saliva of school children, before and after consumption of probiotic and control ice-cream. A double-blind, cross-over, placebo-controlled trial was carried out in forty, 12-14 year-old children, with no clinically detectable caries. The selected children were randomized equally into two groups I and II. Following an initial run-in period of 1 week, children in group I and II were given ice-creams 'A' and 'B', respectively, for 10 days. Being a cross-over study, the ice-creams were interchanged in the two groups after a 2-week wash-out period. Saliva samples at baseline and follow-up were assessed using Dentocult SM and Dentocult LB kits. On statistical evaluation, it was seen that probiotic ice-cream brought about a statistically significant reduction (p-value = 0.003) in salivary mutans streptococci levels with no significant effect on lactobacilli levels. In conclusion, probiotic ice-cream containing Bifidobacterium lactis Bb-12 ATCC27536 and Lactobacillus acidophilus La-5 can reduce the levels of certain caries-associated micro-organisms in saliva.

Background In the coming years, a nutraceutical food may provide both physical and mental benefits that are commonly attributed to the active components of the food. Objective In this study, we determined the nutrient and mineral contents, sensory properties, and physical and chemical characteristics of ice creams manufactured using peach fibre at different concentrations (1 and 2%). Method A total of five experimental groups were formed: two types (from peach peel and pulp) of flour, two fibre concentrations (1 and 2%), and a control group without fibres. Results Flour obtained from peach pulp and peel was found to have a significant (p<0.05) effect on the chemical composition and elemental composition of ice cream samples, especially the rates of Ca, K, Mg, and P, which increased in the samples depending on the content of peach fibre. Sensory ratings and acceptability of ice creams decreased significantly with increasing peach peel fibre, whereas ice creams made with C (control) and B1 (ice creams made from 1% peach pulp fibre) was the highest scored by the panellists. Conclusions Peach fibre concentrates might be used as a good source of nutraceutical ingredients. PMID:27814781

Mercury is considered one of the most toxic elements for plants and animals. Nevertheless, in the Middle East, Asia and Latin America, whitening creams containing mercury are being manufactured and purchased, despite their obvious health risks. Due to the mass distribution of these products, this can be considered a global public health issue. In Mexico, these products are widely available in pharmacies, beauty aid and health stores. They are used for their skin lightening effects. The aim of this work was to analyze the mercury content in some cosmetic whitening creams using the cold vapor technique coupled with atomic absorption spectrometry (CV-AAS). A total of 16 skin-lightening creams from the local market were investigated. No warning information was noted on the packaging. In 10 of the samples, no mercury was detected. The mercury content in six of the samples varied between 878 and 36,000 ppm, despite the fact that the U.S. Food and Drug Administration (FDA) has determined that the limit for mercury in creams should be less than 1 ppm. Skin creams containing mercury are still available and commonly used in Mexico and many developing countries, and their contents are poorly controlled. PMID:21776243

SDZ ASM 981 is a selective inhibitor of the production of pro-inflammatory cytokines from T cells and mast cells in vitro. It is the first ascomycin macrolactam derivative under development for the treatment of inflammatory skin diseases. This study was designed to determine the safety and efficacy of SDZ ASM 981 cream at concentrations of 0.05%, 0.2%, 0.6% and 1.0% in the treatment of patients with atopic dermatitis and to select the concentration to be used in phase III studies. This was a double-blind, randomized, parallel-group, multicentre dose-finding study. A total of 260 patients were randomly assigned to treatment with SDZ ASM 981 cream at concentrations of 0.05%, 0.2%, 0.6%, or 1.0%, matching vehicle cream, or the internal control 0.1% betamethasone-17-valerate cream (BMV). Treatment was given twice daily for up to 3 weeks. A clear dose-response relationship for SDZ ASM 981 was evident, with 0.2%, 0.6% and 1.0% SDZ ASM 981 creams all being significantly more effective than vehicle (P = 0.041, 0.001 and 0.008, respectively) in terms of baseline to end-point changes in the Eczema Area Severity Index (EASI) and pruritus score. The 1.0% cream was the most effective SDZ ASM 981 concentration. BMV was more effective than the SDZ ASM 981 creams tested in this study. It appears that the efficacy plateau was not reached with the SDZ ASM 981 creams within 3 weeks treatment. SDZ ASM 981 was well tolerated. Burning or a feeling of warmth were the only adverse events reported more frequently in the 0.6% and 1.0% SDZ ASM 981 treatment groups than in the vehicle treatment group (42.9%, 48.9% and 34.9%, respectively). Few systemic adverse events were reported during the study (headache was the most frequent systemic event reported by 15 of 252 patients) and none was considered to be related to treatment. The local tolerability profile of the 1.0% cream was similar to that of the lower concentrations. 1.0% SDZ ASM 981 cream, which was shown to be safe, well tolerated and the most effective concentration in this study, was selected as the concentration to be further developed in phase III studies.

Standard guidelines of care: CO2 laser for removal of benign skin lesions and resurfacing.

PubMed

Krupashankar, D S

2008-01-01

Resurfacing is a treatment to remove acne and chicken pox scars, and changes in the skin due to ageing. MACHINES: Both ablative and nonablative lasers are available for use. CO 2 laser is the gold standard in ablative lasers. Detailed knowledge of the machines is essential. INDICATIONS FOR CO 2 LASER: Therapeutic indications: Actinic and seborrheic keratosis, warts, moles, skin tags, epidermal and dermal nevi, vitiligo blister and punch grafting, rhinophyma, sebaceous hyperplasia, xanthelasma, syringomas, actinic cheilitis angiofibroma, scar treatment, keloid, skin cancer, neurofibroma and diffuse actinic keratoses. CO 2 laser is not recommended for the removal of tattoos. AESTHETIC INDICATIONS: Resurfacing for acne, chicken pox and surgical scars, periorbital and perioral wrinkles, photo ageing changes, facial resurfacing. PHYSICIANS' QUALIFICATIONS: Any qualified dermatologist (DVD or MD) may practice CO 2 laser. The dermatologist should possess postgraduate qualification in dermatology and should have had specific hands-on training in lasers either during postgraduation or later at a facility which routinely performs laser procedures under a competent dermatologist/plastic surgeon, who has experience and training in using lasers. For the use of CO 2 lasers for benign growths, a full day workshop is adequate. As parameters may vary in different machines, specific training with the available machine at either the manufacturer's facility or at another centre using the machine is recommended. CO 2 lasers can be used in the dermatologist's minor procedure room for the above indications. However, when used for full-face resurfacing, the hospital operation theatre or day care facility with immediate access to emergency medical care is essential. Smoke evacuator is mandatory. Detailed counseling with respect to the treatment, desired effects, possible postoperative complications, should be discussed with the patient. The patient should be provided brochures to study and also given adequate opportunity to seek information. Detailed consent forms need to be completed by the patients. Consent forms should include information on the machine used; possible postoperative course expected and postoperative complications. Preoperative photography should be carried out in all cases of resurfacing. Choice of the machine and the parameters depends on the site, type of lesion, result needed, and the physician's experience. Localized lesions can be treated under eutectic mixture of local anesthesia (EMLA) cream anesthesia or local infiltration anesthesia. Full-face resurfacing can be performed under general anesthesia. Proper postoperative care is important to avoid complications.

Objective: To evaluate the efficacy and safety of luliconazole cream 1% applied once daily for 14 days in patients with interdigital tinea pedis. Design: Multicenter, randomized, double-blind, parallel-group, vehicle-controlled study. Setting: Private dermatology clinics and clinical research centers in the United States and Central America. Participants: Three hundred twenty-two male and female patients ≥12 years of age diagnosed with interdigital tinea pedis. Measurements: Complete clearance (i.e., clinical and mycological cure), effective treatment, and fungal culture and susceptibility. Results: At study Day 42, complete clearance was obtained by a larger percentage (14.0% [15/107] vs. 2.8% [3/107]; p<0.001) of patients treated with luliconazole cream 1% compared with vehicle. Also at Day 42, more luliconazole-treated patients compared with vehicle-treated patients obtained effective treatment (32.7% vs. 15.0%), clinical cure (15.0% vs. 3.7%), and mycologic cure (56.1% vs. 27.1%). Erythema, scaling, and pruritus scores were lower for the luliconazole cream 1% group compared with vehicle on Day 14, Day 28, and Day 42. For all species and the same isolates, the MIC50/90 for luliconazole cream 1% was 6- to 12-fold lower than for other agents tested. No patients discontinued treatment because of a treatment-emergent adverse event. Conclusion: Luliconazole cream 1% was safe and well-tolerated and demonstrated significantly greater efficacy than vehicle cream in patients with interdigital tinea pedis. PMID:25371767

2017-12-01

Fresh natural latex (around 40% rubber and 60% water) can be transformed to concentrated natural latex (around 60% rubber and 40% water) in order to realise economical transportation and easier latex product’s preparation. The concentrated natural latex is an extremely valuable material. It can be applied for many types of products, for example, foam rubber as pillow and mattress, elastic band, etc. Industrially, the concentrated natural latex can be prepared by centrifugation which requires an enormous expensive machine. From the eco-friendly products point of view, most of rubber entrepreneurs in the world try to develop a green rubber product. So, the main objective of this study is to prepare the cream concentrated latex without any sophisticated machine. Thus, we work on a simple, cheap and green method that does not use any expensive machine but uses water-based chemical as sodium alginate to prepare the cream concentrated latex. The optimal amount of sodium alginate in the latex was studied. The main characteristics of the cream concentrated latex were tested by various technics, such as alkalinity, total solid content (TSC), dry rubber content (DRC), etc. We found that there are no significant differences of results between fresh natural latex and cream concentrated latex, except for the TSC and DRC. The TSC and DRC of cream latex are higher than those of fresh natural latex. Finally, we propose a model of natural rubber particle and sodium alginate to form the cream concentrated latex.

Medicines for the treatment of rare diseases frequently do not attract the interest of the pharmaceutical industry, and hospital pharmacists are thus often requested by physicians to prepare personalized medicines. Tuberous Sclerosis Complex (TSC) is a rare disease that causes disfiguring lesions named facial angiofibromas. Various topical formulations of rapamycin (=sirolimus) have been proved effective in treating these changes in small case series. The present study provides for the first time characterization of a 0.1% rapamycin cream formulation presenting good rapamycin solubilisation. The first step of the formulation is solubilisation of rapamycin in Transcutol(®), and the second step is the incorporation of the mixture in an oil-in-water cream. A HPLC stability-indicating method was developed. Rapamycin concentration in the cream was tested by HPLC and confirmed that it remained above 95% of the initial concentration for at least 85days, without characteristic degradation peaks. The preparation met European Pharmacopoeia microbial specifications throughout storage in aluminum tubes, including when patient use was simulated. Odour, appearance and colour of the preparation were assessed and no change was evidenced during storage. The rheological properties of the cream also remained stable throughout storage. To conclude, we report preparation of a novel cream formulation presenting satisfactory rapamycin solubilisation for the treatment of TSC cutaneous manifestations, with stability data. The cream is currently being used by our patients. Efficacy and tolerance will be reported later. Copyright © 2016 Elsevier B.V. All rights reserved.

Background: Acne vulgaris is almost a widespread disease occurring in all races. Propionibacterium acnes initiate acne and inflammatory mediators aggravate it. Conventional therapies for acne include comedolytic, anti-inflammatory, and anti-biotic agents. Due to adverse effects of these therapies, people are searching for alternative options. In this context, a polyherbal formulation AHPL/AYTOP/0213 cream was developed for the treatment of Acne. Objective: The objective of this study is to study anti-inflammatory and antimicrobial activities of AHPL/AYTOP/0213 cream. Materials and Methods: Skin irritation study was conducted on AHPL/AYTOP/0213 cream as per OECD guidelines. (1) Anti-inflammatory activity: Anti-inflammatory activity of AHPL/AYTOP/0213 cream in comparison with diclofenac sodium cream was assessed in carrageenan-induced rat paw edema model. (2) Antimicrobial activity for P. acnes: P. acnes were incubated under anaerobic conditions. Aliquots of molten brain–heart infusion with glucose agar were used as the agar base. Formulation and clindamycin (10 mg/ml) were introduced in to the Agar wells randomly. (3) Antimicrobial activity for Staphylococcus epidermidis and Staphylococcus aureus: bacteria were incubated under aerobic conditions at 37°C. Tryptic soy broth with glucose agar was used as the agar base. A volume of 0.5 ml of formulation and clindamycin (10 mg/ml) were introduced in to the wells randomly. The antibacterial activity was evaluated by measuring zones of inhibition (in mm). Results: AHPL/AYTOP/0213 cream is nonirritant. Significant reduction in rat paw edema (43%) was observed with AHPL/AYTOP/0213 which was also comparable to diclofenac sodium cream (56.09%). Zone of inhibition for formulation was 20.68 mm, 28.20 mm, and 21.40 mm for P. acnes, S. epidermidis and S. aureus, respectively, which was comparable to clindamycin. The minimum inhibitory concentration of formulation AHPL/AYTOP/0213 obtained in anti-microbial study was 2.5 mg/mL. Conclusion: AHPL/AYTOP/0213 cream is nonirritant and possesses significant anti-inflammatory and antimicrobial activities, which further justifies its role in the management of acne vulgaris.

It seems evident from a wealth of scientific research that mercury is toxic. Because of the nature of the Saudi markets, different brands of skin-lightening creams are widely available. In this study, 38 skin-lightening cream samples were collected and analyzed for mercury by inductively coupled plasma spectrometry after an acid digestion procedure. About 45% of the tested skin-lightening cream samples contained mercury at levels well above the FDA's acceptable limit of 1 ppm. These findings are alarming and have wide legal and educational implications for Saudi Arabia in particular and developing countries in general. Further investigation for possible adverse health effects is also needed.

The balloon-borne Cosmic Ray Energetics And Mass (CREAM) experiment was launched from McMurdo Station Antarctica on December 1, 2009, an early-launch record for Antarctic Long Duration Balloon (LDB) flights. A cumulative exposure of ˜ 156 days was achieved when this 37-day fifth flight of CREAM was terminated over the Ross Ice Shelf on January 8, 2010. Combining a sampling calorimeter for energy measurement with multiple charge detectors for particle identification, CREAM-V provided a large data sample to measure elemental spectra for 1 ≤ Z ≤ 26 in energies above 1014 eV. This was the first time that CREAM was supported with the standard Support Instrumentation Package (SIP) for LDB payloads. The first four flights were supported by the Command and Data Module (CDM) developed by the NASA Wallops Flight Facility for Ultra Long Duration Balloon (ULDB) flights. The instrument performance, results from the ongoing data analysis, and future plans will be presented.

This study aimed to obtain the optimum formulation for stabilizers in ice cream that could contest with blends presented nowadays. Thus, different mixtures of three stabilizers, i.e. basil seed gum, carboxymethyl cellulose, and guar gum, at two concentrations (0.15 % & 0.35 %) were studied using mixture design methodology. The influence of these mixtures on some properties of ice cream and the regression models for them were also determined. Generally, high ratios of basil seed gum in mixture developed the apparent viscosity of ice cream mixes and decreased the melting rate. Increasing proportion of this stabilizer as well as guar gum in the mixtures at concentration of 0.15 % enhanced the overrun of samples. Based on the optimization criteria, the most excellent combination was 84.43 % basil seed gum and 15.57 % guar gum at concentration of 0.15 %. This research proved the capability of basil seed gum as a novel stabilizer in ice cream stabilization.

Tinea pedis, both in its acute and chronic phase, is a common skin condition that often is overlooked but can lead to onychomycosis and acute bacterial cellulitis if left untreated. Therefore, aggressive treatment with a topical antifungal agent is warranted. Sertaconazole nitrate cream 2% is a newer imidazole agent that possesses both fungicidal and fungistatic properties to eradicate existing infections. In addition to antifungal properties, it exhibits anti-inflammatory and antipruritic effects. Controlled clinical trials have confirmed its safety, tolerability, and efficacy in participants with tinea pedis. We report 2 patients with chronic tinea pedis of many years' duration and demonstrate the usefulness of sertaconazole nitrate cream 2% in the clinical setting. Tinea pedis was confirmed by results of a potassium hydroxide preparation. Both patients experienced marked improvement by the second week of twice-daily treatment with sertaconazole nitrate cream 2%. Clinical cure was achieved in both patients. These findings suggest that sertaconazole nitrate cream 2% is an effective option for the treatment of tinea pedis.

Selected volatile compounds of chocolate ice creams containing 0.6, 4.0, 6.0, or 9.0% milk fat or containing 2.5% milk fat, cocoa butter, or one of three fat replacers (Simplesse, Dairy Lo, or Oatrim) were analyzed by gas chromatography and gas chromatography-mass spectrometry using headspace solid-phase microextraction. The headspace concentration of most of the selected volatile compounds increased with decreasing milk fat concentration. Fat replacers generally increased the concentration of volatiles found in the headspace compared with milk fat or cocoa butter. Few differences in flavor volatiles were found between the ice cream containing milk fat and the ice cream containing cocoa butter. Among the selected volatiles, the concentration of 2,5-dimethyl-3(2-methyl propyl) pyrazine was the most highly correlated (negatively) with the concentration of milk fat, and it best discriminated among ice creams containing milk fat, cocoa butter, or one of the fat replacers.

Incontinence-associated dermatitis (IAD) is a common skin disorder affecting patients with urinary and/or faecal incontinence. Maintaining the skin's integrity is a challenge, particularly in the elderly and individuals with medical or surgical comorbidities. It is widely reported that the issue is complex and recognition is inconsistent, with symptoms often being confused with those of pressure ulcers. This article explores the causes of IAD, looking at the structure of healthy skin and the pathology that occurs during skin breakdown. It identifies risk factors and prevention and management strategies, including the use of barrier creams. The article then presents the results of a large product evaluation that took place with Cavilon Durable Barrier Cream (3M). The barrier cream was shown to be more effective in treating and managing patients with IAD than the previous product that patients had been using. A case study is also included to demonstrate the efficacy of the newest version of Cavilon Durable Barrier Cream.

Vulvovaginal candidiasis is one of the most common infections of the genital tract in women that causes many complications. Therefore, we examined the clinical effect of ginger cream along with clotrimazole compared to vaginal clotrimazole alone in this study. This double-blind clinical trial was conducted on 67 women admitted to the Gynecology Clinic of Hajar Hospital with vaginal candidiasis. The patients were divided randomly into two groups of 33 and 34 people. The diagnosis was made according to clinical symptoms, wet smear, and culture. Ginger-clotrimazole vaginal cream 1% and clotrimazole vaginal cream 1% were administered to groups 1 and 2, respectively, once a day for 7 days and therapeutic effects and symptoms were evaluated in readmission. Data analysis was performed using SPSS version 22, t -test and Chi-square. The mean value of variables itching ( P > 0.05), burning ( P > 0.05), and cheesy secretion ( P < 0.05) in users of ginger-clotrimazole was less than the other group after the treatment. Recurrence in clotrimazole group was 48.5% and in ginger-clotrimazole group 51.2% during the 1-month follow-up with no significant difference. Study results showed that cream containing ginger and clotrimazole 1% was more effective and may be more useful than the clotrimazole to treat vaginal candidiasis.

Microbial transglutaminase (MTGase) has been currently utilized to form new food structures and matrices with high physicochemical stability. Incorporation of this multi-functional enzyme into structural composition of milk protein-based products, such as cheese and ice cream, can not only be a successful strategy to improve their nutritional and technological characteristics through intramolecular cross-linking, but also to reduce the production cost by decreasing fat and stabilizer contents. The recent research developments and promising results of MTGase application in producing functional formulations of cheese and ice cream with higher quality characteristics are reviewed. New interesting insights and future perspectives are also presented. The addition of MTGase to cheese led to significant improvements in moisture, yield, texture, rheology and sensory properties, without changes in the chemical composition. Furthermore, pH value of ice cream is not affected by the MTGase treatment. Compared to untreated ice creams, application of MTGase significantly promotes consistency, fat destabilization, overrun and organoleptic acceptance, while a substantial reduction in firmness and melting rate of samples was observed. The addition of MTGase to cheese and ice cream-milk provides reinforcement to the protein matrix and can be considered as a novel additive for improving the physicochemical and organoleptic properties of final products.

The cognitive mechanism underlying the association between individual differences in reward sensitivity and food craving is unknown. The present study explored the mechanism by examining the role of reward sensitivity in attentional bias toward ice cream cues. Forty-nine college students who displayed high level of ice cream craving (HICs) and 46 who displayed low level of ice cream craving (LICs) performed an inattentional blindness (IB) task which was used to assess attentional bias for ice cream. In addition, reward sensitivity and coping style were assessed by the Behavior Inhibition System/Behavior Activation System Scales and Simplified Coping Style Questionnaire. Results showed significant higher identification rate of the critical stimulus in the HICs than LICs, suggesting greater attentional bias for ice cream in the HICs. It was indicated that attentional bias for food cues persisted even under inattentional condition. Furthermore, a significant correlation was found between the attentional bias and reward sensitivity after controlling for coping style, and reward sensitivity predicted attentional bias for food cues. The mediation analyses showed that attentional bias mediated the relationship between reward sensitivity and food craving. Those findings suggest that the association between individual differences in reward sensitivity and food craving may be attributed to attentional bias for food-related cues.

The effect of the Lactobacillus casei 01 and inulin addition on sheep milk ice cream during storage (-18 °C, 150 days) was investigated. Control, probiotic and synbiotic ice cream (10% w/w sheep milk cream; 10% w/w sheep milk cream, L. casei 01, 6 log CFU/mL; 10% w/w inulin, L. casei 01, 6 log CFU/mL, respectively) were manufactured. Microbiological counts (probiotic count, survival after in vitro gastrointestinal resistance, Caco-2 cell adhesion), bioactivity and microstructure were analysed. Physical and textural characteristics, colour parameters, thermal analysis and organic acids/volatile compounds were also evaluated. All formulations supported L. casei 01 viability and maintained above the minimum therapeutic level (>6 log CFU/mL) during storage. Inulin did not affect L. casei 01 survival after the passage through simulated gastrointestinal tract and adhesion to Caco-2 cells while improved the ACE-inhibitory and antioxidant activity. L. casei 01 addition produced several volatile compounds, such as carboxylic acids, alcohols, aldehydes and ketones. Also, scanning electron microscopy showed an interaction between probiotic bacteria and inulin fibre on synbiotic ice cream and the adhesion of L. casei to Caco-2 cells was observed.

Parente, María Emma; Gámbaro, Adriana; Boinbaser, Lucía; Roascio, Antonella

2014-01-01

Perceptions of essences for potential use in the development of a line of cosmetic emulsions containing olive oil were studied. Six cream samples prepared with six essences selected in a preliminary study were evaluated for overall liking and intention to purchase by a 63-women sample. A check-all-that-apply (CATA) question consisting of 32 terms was used to gather information about consumer perceptions of fragrance, affective associations, effects on the skin, price, target market, zones of application, and occasions of use. Hierarchical cluster analysis led to the identification of two consumer clusters with different frequency of use of face creams. The two clusters assigned different overall liking scores to the samples and used the CATA terms differently to describe them. A fragrance with jasmine as its principal note was selected for further development of cosmetic creams, as it was awarded the highest overall liking scores by respondents of the two clusters, and was significantly associated with cosmetic features including nourishing, moisturizing, softening, with a delicious and mild smell, and with a natural image, as well as being considered suitable for face and body creams. The use of CATA questions enabled the rapid identification of attributes associated by respondents with a cosmetic cream's fragrance, in addition to contributing relevant information for the definition of marketing and communication strategies.

Interdigital tinea pedis is one of the most common clinical presentations of dermatophytosis. This phase 3 study evaluated the safety and efficacy of luliconazole cream 1% in patients with tinea pedis. A total of 321 male and female patients aged ≥12 years with tinea pedis and eligible for modified intent-to-treat analysis were randomized 1:1 to receive luliconazole cream 1% (n=159) or vehicle (n=162) once daily for 14 days. Efficacy was evaluated at days 28 and 42 (i.e., days 14 and 28 posttreatment) based on clinical signs (erythema, scaling, pruritus) and mycology (KOH, fungal culture). The primary outcome was complete clearance at day 42. Safety evaluations included adverse events and laboratory assessments. Complete clearance at day 42 was achieved in 26.4% (28/106) of patients treated with luliconazole cream 1% compared with 1.9% (2/103) of patients treated with vehicle (P< 0.001). Similar safety profiles were obtained for luliconazole cream 1% and vehicle. This study was conducted in a relatively small population under controlled clinical trial conditions. Luliconazole cream 1% applied once daily for 14 days is well tolerated and more effective than vehicle in patients with tinea pedis.

Objective: To compare the efficacy and safety of a 3-day regimen of clindamycin vaginal ovules with a 7-day regimen of clindamycin vaginal cream for the treatment of bacterial vaginosis (BV) Methods: Women with a clinical diagnosis of BV were treated with a 3-day course of clindamycin ovules or a 7-day course of clindamycin cream administered intravaginally. Three hundred and eighty-four patients received study drug and were included in the evaluable patient population (ovule group, n = 204; cream group, n = 180). Assessments included pelvic examination and diagnostic testing. Primary efficacy endpoints were a resolution of two of three diagnostic criteria at the first follow-up visit and three of three diagnostic criteria at the second. Results: Cure rates in the evaluable patient population were similar between treatment groups: 53.7% (109/204) for the ovule group and 47.8% (85/180) for the cream group (p = 0.2471, 95% CI– 4.1–16.0%). The most commonly reported medical event, vulvovaginal pruritus, had similar incidence in both treatment groups. Conclusions: A 3-day course of clindamycin vaginal ovules is as effective and well-tolerated as a 7-day course of clindamycin vaginal cream in the treatment of BV. PMID:11368263

Hydroquinone neuropathy following use of skin bleaching creams: case report.

A 30-year old black woman presented with gradual onset of weakness of the legs associated with burning sensation in the feet for two months. She had been using two hydroquinone based skin bleaching creams (MGC by M. G. C. International, MEKAKO by Anglo Fabrics BOLTON Ltd) for about four years. Her BP was 80/40 mm Hg supine with un-recordable diastolic pressure on standing. She had decreased power (Grade 3/5), loss of deep tendon reflexes and impairment of deep sensation in the lower limbs. A complete blood count, urinalysis, serum electrolytes, serum creatinine and uric acid were all normal. Oral GTT, VDRL and brucella tests were negative. Chest and abdominal radiographs did not show any abnormalities. A diagnosis of peripheral neuropathy with autonomic neuropathy possibly due to hydroquinone toxicity was made and she was advised to stop using hydroquinone based skin bleaching creams. Four months later she was asymptomatic, her BP was 120/80 mmHg supine and standing, and neurological examination was normal. The case raises the question of whether hydroquinone based skin bleaching creams could be a cause of peripheral neuropathy and underscores the need for research on hydroquinone based skin bleaching creams and neuropathy particularly in black women involved in the sale and/or use of skin bleaching creams.

The efficacy of aloe extract in reducing radiation-induced skin injury is controversial. The purpose of the present 3-arm randomized trial was to test the efficacy of quality-tested aloe extract in reducing the severity of radiation-induced skin injury and, secondarily, to examine the effect of a moist cream versus a dry powder skin care regimen. A total of 248 patients with breast cancer were randomized to powder, aloe cream, or placebo cream. Acute skin toxicity was scored weekly and after treatment at weeks 1, 2, and 4 using a modified 10-point Catterall scale. The patients scored their symptom severity using a 6-point Likert scale and kept an acute phase diary. The aloe formulation did not reduce acute skin toxicity or symptom severity. Patients with a greater body mass index were more likely to develop acute skin toxicity. A similar pattern of increased skin reaction toxicity occurred with both study creams compared with the dry powder regimen. No evidence was found to support prophylactic application of quality aloe extract or cream to improve the symptoms or reduce the skin reaction severity. Our results support a dry skin care regimen of powder during radiation therapy. Copyright © 2015 Elsevier Inc. All rights reserved.

Determination of CME 3D parameters based on a new full ice-cream cone model

In space weather forecast, it is important to determine three-dimensional properties of CMEs. Using 29 limb CMEs, we examine which cone type is close to a CME three-dimensional structure. We find that most CMEs have near full ice-cream cone structure which is a symmetrical circular cone combined with a hemisphere. We develop a full ice-cream cone model based on a new methodology that the full ice-cream cone consists of many flat cones with different heights and angular widths. By applying this model to 12 SOHO/LASCO halo CMEs, we find that 3D parameters from our method are similar to those from other stereoscopic methods (i.e., a triangulation method and a Graduated Cylindrical Shell model). In addition, we derive CME mean density (ρmean=Mtotal/Vcone) based on the full ice-cream cone structure. For several limb events, we determine CME mass by applying the Solarsoft procedure (e.g., cme_mass.pro) to SOHO/LASCO C3 images. CME volumes are estimated from the full ice-cream cone structure. From the power-law relationship between CME mean density and its height, we estimate CME mean densities at 20 solar radii (Rs). We will compare the CME densities at 20 Rs with their corresponding ICME densities.

Over the past decades, the number of childhood obesity cases has increased significantly, which led to an increase in the number of adults suffering from degenerative diseases such as diabetes mellitus (DM). Glucomannan-Enriched Soy Milk Ice Cream (GSMIC) may prevent obesity in children. The aim of the study was to test the level of carbohydrates, protein, fat, dietary fiber, glycemic index, glycemic load, and organoleptic quality of GSMIC. This experiment used a completely randomized design to test three formulations of glucomannan flour and soy milk (0.5%, 1.5%, and 2.5%). The products were tested for nutritional composition, and evaluated on glycemic index, glycemic load, and organoleptic quality. GSMIC 2.5% had higher levels of dietary fiber and high carbohydrate, protein, and fat content compared to ice cream (3.99%, 30.7%, 1.50%, 1.33%, respectively). The glycemic index of ice cream and 2.5% GSMIC were 75.83 (75%) and 51.48 (51%), respectively, while the glycemic load of ice cream and 2.5% GSMIC were 9.04 and 11.61, respectively. Based on the organoleptic analysis, formulation preferred by the panellists was 2.5% glucomannan flour. Glucomannan flour affected the level of carbohydrates, protein, fat, dietary fiber, glycemic index, glycemic load, and organoleptic quality in soy milk ice cream.

The skin is a barrier membrane that separates environments with profoundly different water contents. The barrier properties are assured by the outer layer of the skin, the stratum corneum (SC), which controls the transepidermal water loss. The SC acts as a responding membrane, since its hydration and permeability vary with the boundary condition, which is the activity of water at the outer surface of the skin. We show how this boundary condition can be changed by the application of a barrier cream that makes a film with a high resistance to the transport of water. We present a quantitative model that predicts hydration and water transport in SC that is covered by such a film. We also develop an experimental method for measuring the specific resistance to water transport of films made of occluding barrier creams. Finally, we combine the theoretical model with the measured properties of the barrier creams to predict how a film of cream changes the activity of water at the outer surface of the SC. Using the known variations of SC permeability and hydration with the water activity in its environment (i.e. the relative humidity), we can thus predict how a film of barrier cream changes SC hydration.

The formation of radicals plays an important role in the development of atopic eczema or barrier-disrupted skin. We evaluated the radical scavenging effect of a cream containing a Hypericum perforatum extract rich in hyperforin in a double-blind placebo-controlled study on 11 healthy volunteers. Electron paramagnetic resonance spectroscopy was applied to determine radical formation during VIS/NIR irradiation of the inner forearm. The results were compared to ex vivo investigations on excised porcine ear skin after a single application of the creams. The non-treated skin was measured as control. The absolute values and the kinetics are not comparable for ex vivo and in vivo radical formation. Whereas in vivo, the radical production decreases with time, it remains stable ex vivo over the investigated timescale. Nevertheless, ex vivo methods could be developed to estimate the protection efficiency of creams. In vivo as well as ex vivo, the radical formation could be reduced by almost 80% when applying the hyperforin-rich cream onto the skin, whereas placebo resulted in about 60%. In vivo, a daylong protection effect could be validated after a 4-week application time of the cream indicating that a regular application is necessary to obtain the full effect. © 2013 John Wiley & Sons A/S.

The exposure to ultraviolet radiations (UVR) is the key source of skin sunburn; it may produce harmful entities, reactive oxygen species (ROS), leading to aging. The skin can be treated and protected from the injurious effects of ROS by using various pharmaceutical formulations, such as cream. Cream can be loaded with antioxidants to quench ROS leading to photo-protective effects. Moreover, modern medicines depend on ethnobotanicals for protection or treatment of human diseases. This review article summarizes various in vivo antioxidant studies on herbal creams loaded with phyto-extracts. These formulations may serve as cosmeceuticals to protect skin against injurious effects of UVR. The botanicals studied for dermatologic use in cream form include Acacia nilotica, Benincasa hispida, Calendula officinalis, Camellia sinensis, Camellia sinensis, Nelumbo nucifera, Capparis decidua, Castanea sativa, Coffea arabica, Crocus sativus, Emblica officinalis Gaertn, Foeniculum vulgare, Hippophae rhamnoides, Lithospermum erythrorhizon, Malus domestica, Matricaria chamomilla L., Moringa oleifera, Morus alba, Ocimum basilicum, Oryza sativa, Polygonum minus, Punica granatum, Silybum marianum, Tagetes erecta Linn., Terminalia chebula, Trigonella foenum-graecum, and Vitis vinifera. The observed anti-aging effects of cream formulations could be an outcome of a coordinating action of multiple constituents. Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed.

Children suffered from leukemia want to eat delicious dishes, such as cake and ice cream. However, it is very difficult to serve these foods to immune-compromised patients without application of any adequate sanitary measures. This study was conducted to evaluate application of irradiation to frozen ready-to-eat food, ice cream. Three ice creams with flavors of vanilla, chocolate and strawberry were manufactured and gamma irradiated at the absorbed doses of 1, 3, and 5 kGy at -70 °C. Total microflora and coliform bacteria were determined, and Listeria spp., Escherichia coli and Salmonella spp. were also tested by the use of API 20E Kit. Aerobic bacteria, yeast/mold and coliforms were contaminated in the levels of 2.3 to 3.3, 2.3 to 2.7 and 1.7 to 2.4 log CFU/g, respectively. In samples irradiated at 5 kGy, the growth of any microorganisms could not be observed. Listeria spp. and E. coli were detected at non-irradiated samples, but S. spp. was not existed. D10 values of L. ivanovii and E. coli were 0.75 and 0.31 kGy, respectively, in ice cream. From these results, irradiation technology can reduce the risk by the food-borne pathogens of ice cream.

A non-destructive method for monitoring creaming of emulsion-based formulations is in great demand because it allows us to understand fully their instability mechanisms. This study was aimed at demonstrating the usefulness of magnetic resonance (MR) techniques, including MR imaging (MRI) and MR spectroscopy (MRS), for evaluating the physicochemical stability of emulsion-based formulations. Emulsions that are applicable as the base of practical skin creams were used as test samples. Substantial creaming was developed by centrifugation, which was then monitored by MRI. The creaming oil droplet layer and aqueous phase were clearly distinguished by quantitative MRI by measuring T1 and the apparent diffusion coefficient. Components in a selected volume in the emulsions could be analyzed using MRS. Then, model emulsions having different hydrophilic-lipophilic balance (HLB) values were tested, and the optimal HLB value for a stable dispersion was determined. In addition, the MRI examination enables the detection of creaming occurring in a polyethylene tube, which is commonly used for commercial products, without losing any image quality. These findings strongly indicate that MR techniques are powerful tools to evaluate the physicochemical stability of emulsion-based formulations. This study will make a great contribution to the development and quality control of emulsion-based formulations.

Dental caries is one of the most common health problems in the world. Probiotics are one the various preventive methods to reduce dental caries. The aim of this study is to compare the effectiveness of probiotic ice cream and drink on salivary Streptococcus mutans levels in children of 6-12 years age group. A three phase study was carried out in children (n = 50) of 6-12 years age with zero decayed missing filled teeth (dmft)/DMFT. They were randomly divided into two equal groups. Saliva samples were collected before the consumptions of probiotic ice cream and probiotic drink. Colony count obtained was recorded as baseline data. For both groups probiotic ice cream and drink was given randomly for 7 days and a washout period of 90 days were given and then the saliva samples were collected and colony counting was done. Statistical analysis was performed using Student's paired t-test and multiple comparisons by Tukey's honest significant difference test which showed, there is a significant reduction in salivary S. mutans level in both groups after 7 days period. However, after washout period only probiotic ice cream showed reduction whereas drink did not. Also, there was no significant difference between probiotic ice cream and drink. Probiotic organisms definitely have a role in reducing the salivary S. mutans level and ice cream would be a better choice than drink. However, the prolonged use of the agents and their effects on caries is still to be determined.

Numerous modalities have been used to treat keloids and hypertrophic scars; however, optimal treatment has not yet been established. Therefore, prevention is the mainstay. Recently, silicone gel and tretinoin cream have been shown to be useful for the prevention of hypertrophic scars and keloids. However, there has been no comparative study of the two topical agents thus far. To determine and compare the effectiveness of silicone gel and tretinoin cream for the prevention of hypertrophic scars and keloids resulting from postoperative wounds and for scar improvement. This study included 26 patients with 44 different wounds. The postoperative wounds were divided into two treatment groups and one control group. The patients in the first and second treatment group applied silicone gel and tretinoin cream, respectively, twice a day on their wounds after their stitches were removed. In contrast, the control group patients did not apply anything. We used the Modified Vancouver Scar Scale to quantitatively examine the effectiveness of silicone gel and tretinoin cream just after stitches removal, and at 4, 8, 12 and 24 weeks after removal of the stitches. The silicone gel and tretinoin cream effectively prevented hypertrophic scars and keloids and improved scar effects in the two treatment groups compared with those in the control group. However, no significant difference was noted between the two treatment groups. To prevent hypertrophic scars and keloids and improve scars after surgery, application of a silicone gel or a tretinoin cream to the wounds is needed. © 2013 European Academy of Dermatology and Venereology.

Until recently, no prescription drug containing permethrin for the therapy of scabies was available on the German market.Therefore, a 5% permethrin cream formulation (InfectoScab 5%) was tested in a single-arm multi-center study including adults and children from 3 months of age with proven scabies. On day 0, patients were treated once with permethrin cream in the study center. Control examinations including dermatoscopy were performed on day 14+/-2 and on day 28+/-3. Patients who were not considered cured or who had contact to individuals with untreated scabies received one further treatment with permethrin cream on day 14+/-2. Itching and local tolerability of the cream were documented in patients' diaries. Side effects were assessed by history, skin inspection and evaluation of patients' notes. 106 patients in 13 centers were enrolled in the study. Their mean age was 29.2 years (range, 141 days to 71.9 years); 34% of them were children or adolescents. 78.3% of patients were either severely (3 body sites) or very severely (4-5 sites) affected. The cure rate on day 28+/-3 was 95.1% (95% confidence interval, 91.0-99.3%). Pruritus declined markedly and continuously. In general, the cream was well tolerated; side effects were almost invariably mild. Our results support the efficacy and safety of 5% permethrin cream in adults, children and infants suffering from scabies. These results have contributed to the approval of InfectoScab 5% in Germany for the treatment of scabies in October 2004.

The present work was aimed to develop an antiseptic cream formulation of Indian basil oil utilizing hydrophilic-lipophilic balance approach. In order to determine the required-hydrophilic lipophilic balance (rHLB) of basil oil, emulsions of basil oil were prepared by phase inversion temperature technique using water, Tween 80, and Span 80. Formulated emulsions were assessed for creaming (BE9; 9.8, BE10; 10.2), droplet size (BE18; 3.22 ± 0.09 μm), and turbidity (BE18; 86.12 ± 2.1%). To ensure correctness of the applied methodology, rHLB of light liquid paraffin was also determined. After rHLB determination, basil oil creams were prepared with two different combinations of surfactants, namely, GMS : Tween 80 (1 : 3.45) and SLS : GMS (1 : 3.68), and evaluated for in vitro antimicrobial activity, skin irritation test, viscosity and consistency. The rHLB of basil oil and light liquid paraffin were found to be 13.36 ± 0.36 and 11.5 ± 0.35, respectively. Viscosity, and consistency parameters of cream was found to be consistent over 90 days. Cream formulations showed net zone of growth inhibition in the range of 5.0–11.3 mm against bacteria and 4.3–7.6 mm against fungi. Primary irritation index was found to be between 0.38 and1.05. Conclusively stable, consistent, non-irritant, enriched antiseptic basil oil cream formulations were developed utilizing HLB approach. PMID:23984361

Recent research has shown that high frequency ultrasound (0.4-3 MHz), can enhance milkfat separation in small scale systems able to treat only a few milliliters of sample. In this work, the effect of ultrasonic standing waves on milkfat creaming was studied in a 6L reactor and the influence of different frequencies and transducer configurations in direct contact with the fluid was investigated. A recombined coarse milk emulsion with fat globules stained with oil-red-O dye was selected for the separation trials. Runs were performed with one or two transducers placed in vertical (parallel or perpendicular) and horizontal positions (at the reactor base) at 0.4, 1 and/or 2 MHz (specific energy 8.5 ± 0.6 kJ/kg per transducer). Creaming behavior was assessed by measuring the thickness of the separated cream layer. Other methods supporting this assessment included the measurement of fat content, backscattering, particle size distribution, and microscopy of samples taken at the bottom and top of the reactor. Most efficient creaming was found after treatment at 0.4 MHz in single and double vertical transducer configurations. Among these configurations, a higher separation rate was obtained when sonicating at 0.4 MHz in a vertical perpendicular double transducer setup. The horizontal transducer configuration promoted creaming at 2 MHz only. Fat globule size increase was observed when creaming occurred. This research highlights the potential for enhanced separation of milkfat in larger scale systems from selected transducer configurations in contact with a dairy emulsion, or emulsion splitting in general.

Hydrophilic creams containing clobetasol propionate (CP) or prednisolone (PS) were selected as model steroid formulations. Skin blanching, a*, was determined using a Chroma Meter after the application of 0.005, 0.01, 0.1, or 1.0% CP or PS hydrophilic cream to the back skin of guinea pigs and hairless rats for 24 h. The relationships between Δa*(6h) and the skin concentrations of the steroids were determined at 6 h after removal of the cream. Δa*(6h) was markedly decreased after the application of CP hydrophilic cream to guinea pigs, and a good linear relationship was observed between Δa*(6h) and skin concentration (r=0.98). In contrast, no relationship was observed between these parameters after the application of CP cream to the hairless rats. Although skin blanching was observed after PS cream application in guinea pigs, no relationship was observed between Δa*(6h) and skin concentration of PS in each animal. These results suggest that the skin blanching effect of CP in guinea pigs is greater than that of PS and that its blanching effect in guinea pigs was stronger than that in hairless rats. Guinea pigs were found to be a good animal model for determining the skin blanching produced by steroid creams. In addition, Chroma Meters can be effectively used in skin vasoconstrictive tests in guinea pigs.

The purpose of the study was to evaluate the effect of different homogenization speeds and times, anchor speeds and cooling times on the viscosity and cumulative % clobetasol 17-propionate released per unit area at 72 h from pilot scale cream formulations. A 2(4) full factorial central composite design for four independent variables were investigated. Thirty pilot scale batches of cream formulations were manufactured using a Wintech® cream/ointment plant. The viscosity and in vitro release of CP were monitored and compared to an innovator product that is commercially available on the South African market, namely, Dermovate® cream. Contour and three-dimensional response surface plots were produced and the viscosity and cumulative % CP released per unit area at 72 h were found to be primarily dependent on the homogenization and anchor speeds. An increase in the homogenization and anchor speeds appeared to exhibit a synergistic effect on the resultant viscosity of the cream whereas an antagonistic effect was observed for the in vitro release of CP from the experimental cream formulations. The in vitro release profiles were best fitted to a Higuchi model and diffusion proved to be the dominant mechanism of drug release that was confirmed by use of the Korsmeyer-Peppas model. The research was further validated and confirmed by the high prognostic ability of response surface methodology (RSM) with a resultant mean percentage error of (±SD) 0.17 ± 0.093 suggesting that RSM may be an efficient tool for the development and optimization of topical formulations.

Ice cream is a multiphase frozen food containing ice crystals, air cells, fat globules, and partially coalesced fat globule clusters dispersed in an unfrozen serum phase (sugars, proteins, and stabilizers). This microstructure is responsible for ice cream's melting characteristics. By varying both formulation (emulsifier content and overrun) and processing conditions (dasher speed), the effects of different microstructural elements, particularly air cells and fat globule clusters, on ice cream melt-down properties were studied. Factors that caused an increase in shear stress within the freezer, namely increasing dasher speed and overrun, caused a decrease in air cell size and an increase in extent of fat destabilization. Increasing emulsifier content, especially of polysorbate 80, caused an increase in extent of fat destabilization. Both overrun and fat destabilization influenced drip-through rates. Ice creams with a combination of low overrun and low fat destabilization had the highest drip-through rates. Further, the amount of remnant foam left on the screen increased with reduced drip-through rates. These results provide a better understanding of the effects of microstructure components and their interactions on drip-through rate. Manipulating operating and formulation parameters in ice cream manufacture influences the microstructure (air cells, ice crystals, and fat globule clusters). This work provides guidance on which parameters have most effect on air cell size and fat globule cluster formation. Further, the structural characteristics that reduce melt-down rate were determined. Ice cream manufacturers will use these results to tailor their products for the desired quality attributes. © 2018 Institute of Food Technologists®.

A moisturizing cream mixed with a steroid ointment is frequently prescribed to patients suffering from atopic dermatitis. However, there is a concern that the mixing operation causes destabilization. The present study was performed to investigate the stability of such preparations closely using magnetic resonance imaging (MRI). As sample preparations, five commercial moisturizing creams that are popular in Japan were mixed with an ointment base, a white petrolatum, at a volume ratio of 1 : 1. The mixed preparations were stored at 60°C to accelerate the destabilization processes. Subsequently, the phase separations induced by the storage test were monitored using MRI. Using advanced MR technologies including spin-spin relaxation time (T 2 ) mapping and MR spectroscopy, we successfully characterized the phase-separation behavior of the test samples. For most samples, phase separations developed by the bleeding of liquid oil components. From a sample consisting of an oil-in-water-type cream, Urepearl Cream 10%, a distinct phase-separation mode was observed, which was initiated by the aqueous component separating from the bottom part of the sample. The resultant phase separation was the most distinct among the test samples. To investigate the phase separation quantitatively and objectively, we conducted a histogram analysis on the acquired T 2 maps. The water-in-oil type creams were found to be much more stable after mixing with ointment base than those of oil-in-water type creams. This finding strongly supported the validity of the mixing operation traditionally conducted in pharmacies.

Objective The purpose of this study was to determine the effect of 2 concentrations of topical, comfrey-based botanical creams containing a blend of tannic acid and eucalyptus to a eucalyptus reference cream on pain, stiffness, and physical functioning in those with primary osteoarthritis of the knee. Methods Forty-three male and female subjects (45-83 years old) with diagnosed primary osteoarthritis of the knee who met the inclusion criteria were entered into the study. The subjects were randomly assigned to 1 of 3 treatment groups: 10% or 20% comfrey root extract (Symphytum officinale L.) or a placebo cream. Outcomes of pain, stiffness, and functioning were done on the Western Ontario and MacMaster Universities Osteoarthritis Index. Participants applied the cream 3× a day for 6 weeks and were evaluated every 2 weeks during the treatment. Results Repeated-measures analyses of variance yielded significant differences in all of the Western Ontario and MacMaster Universities Osteoarthritis Index categories (pain P < .01, stiffness P < .01, daily function P < .01), confirming that the 10% and 20% comfrey-based creams were superior to the reference cream. The active groups each had 2 participants who had temporary and minor adverse reactions of skin rash and itching, which were rapidly resolved by modifying applications. Conclusion Both active topical comfrey formulations were effective in relieving pain and stiffness and in improving physical functioning and were superior to placebo in those with primary osteoarthritis of the knee without serious adverse effects.

Algae have gained importance in cosmeceutical product development due to their beneficial effects on skin health and therapeutical value with bioactive compounds. Spirulina platensis Parachas (Phormidiaceae) is renowned as a potential source of high-value chemicals and recently used in skincare products. This study develops and evaluates skin creams incorporated with bioactive S. platensis extract. Spirulina platensis was cultivated, the aqueous crude extract was prepared and in vitro cytotoxicity of S. platensis extract in the range of 0.001-1% concentrations for 1, 3 and 7 d on HS2 keratinocyte cells was determined. Crude extracts were incorporated in skin cream formulation at 0.01% (w/w) concentration and in vitro wound healing and genotoxicity studies were performed. Immunohistochemical staining was performed to determine the collagen activity. 0.1% S. platensis extract exhibited higher proliferation activity compared with the control group with 198% of cell viability after 3 d. Skin cream including 1.125% S. platensis crude extract showed enhanced wound healing effect on HS2 keratinocyte cell line and the highest HS2 cell viability % was obtained with this concentration. The micronucleus (MN) assay results indicated that S. platensis extract incorporated creams had no genotoxic effect on human peripheral blood cells. Immunohistochemical analysis showed that collagen 1 immunoreactivity was improved by increased extract concentration and it was strongly positive in cells treated with 1.125% extract incorporated skin cream. The cell viability, wound healing activity and genotoxicity results showed that S. platensis incorporated skin cream could be of potential value in cosmeceutical and biomedical applications.

The main objective of the present study was to assess efficacy and safety of AHPL/AYTOP/0113 cream, a polyherbal formulation in comparison with Framycetin sulphate cream in acute wounds. It was an open label, randomized, comparative, parallel group and multi-center clinical study. Total 47 subjects were randomly assigned to Group-A (AHPL/AYTOP/0113 cream) and 42 subjects were randomly assigned to Group-B (Framycetin sulphate cream). All the subjects were advised to apply study drug, thrice daily for 21 days or up to complete wound healing (whichever was earlier). All the subjects were called for follow up on days 2, 4, 7, 10, 14, 17 and 21 or up to the day of complete wound healing. Data describing quantitative measures are expressed as mean ± SD. Comparison of variables representing categorical data was performed using Chi-square test. Group-A subjects took significantly less ( P < 0.05) i.e., (mean) 7.77 days than (mean) 9.87 days of Group-B subjects for wound healing. At the end of the study, statistically significant better ( P < 0.05) results were observed in Group-A than Group-B in mean wound surface area, wound healing parameters and pain associated with wound. Excellent overall efficacy and tolerability was observed in subjects of both the groups. No adverse event or adverse drug reaction was noted in any subject of both the groups. AHPL/AYTOP/0113 cream proved to be superior to Framycetin sulphate cream in healing of acute wounds.

This study measured skin hydration and occlusivity of two test products [halobetasol propionate lotion, 0.05% (HBP Lotion) and Ultravate® (halobetasol propionate) cream, 0.05% (HBP Cream)] at 2, 4, and 6 hours after application to skin test sites previously challenged by dry shaving, which was performed to compromise the integrity of the stratum corneum barrier. Trans-epidermal water loss (TEWL), an indicator of skin barrier function, was measured using cyberDERM, inc. RG-1 evaporimeter. Skin hydration was evaluated using IBS SkiCon-200 conductance meter. Test products were applied bilaterally on dry-shaved sites on the volar forearm sites, according to a randomization scheme, with two test sites untreated to serve as "dry-shaved" controls. TEWL and conductance were measured at 2, 4, and 6 hours post-treatment. HBP Lotion displayed a significant increase in skin hydration at 2, 4, and 6 hours post-treatment compared to the baseline values and dry-shaved controls (each, P less than 0.001). However, HBP Cream produced statistically significant increased skin hydration only after 6 hours (P less than 0.05). HBP Lotion was significantly more effective than HBP Cream in increasing skin hydration at 2 and 4 hours post-treatment (each, P less than 0.001), and had a directional advantage (not statistically significant) at 6 hours. Neither test product had a significant occlusive effect as measured by TEWL at 2, 4, and 6 hours post-application. Both formulations of HBP (Lotion and Cream) contributed to skin moisturization, as measured by skin conductance. HBP Lotion produced a significantly more rapid onset and higher level of moisturization at 2 and 4 hours post-application compared to HBP Cream. The TEWL results indicate that neither HBP Lotion nor HBP Cream provided any significant occlusivity to the skin.

The objective of the present study was the assessment and quantitative description of the growth behavior of Listeria monocytogenes as a function of temperature in vanilla cream pudding, formulated with or without cinnamon extract. Commercially prepared pasteurized vanilla cream pudding, formulated with (0.1% w/w) or without cinnamon extract, was inoculated with a five-strain mixture of L. monocytogenes (ca. 2logCFU/g) and stored aerobically at 4, 8, 12 and 16°C. At appropriate time intervals, L. monocytogenes populations were determined, and the primary model of Baranyi and Roberts was fitted to the derived microbiological data for the estimation of the pathogen's growth kinetic parameters. The effect of temperature on maximum specific growth rate (μ max ) was then modeled for each product type using a square-root-type model, and the developed models were validated using independent growth data generated during storage of inoculated vanilla cream samples under dynamic temperature conditions. Although the kinetic behavior of the pathogen was similar in cream with and without cinnamon extract during storage at higher temperatures, significant (P<0.05) differences were observed between the two product types at 4°C. With regard to secondary modelling, the estimated values of T min for cream with and without cinnamon extract were 0.39°C and -2.54°C, respectively, while the dynamic models exhibited satisfactory performance. Finally, as demonstrated by the findings of pulsed-field gel electrophoresis, both temperature and cinnamon extract affected the pathogen's strains dominating during storage. According to the collected data, cinnamon extract exhibits an important potential of enhancing the microbiological safety of vanilla cream pudding, provided that efficient temperature control is in place. The developed models should be useful in quantitative microbial risk assessment regarding the studied cream products. Copyright © 2017 Elsevier Ltd. All rights reserved.

To compare the efficacy of dioctahedral smectite and iodine glycerin (DSIG) cream with topical mouth rinse (composed of saline, gentamicin and Vitamin B12) in treatment of chemotherapy induced oral mucositis (OM). A total of 130 intensive chemotherapy or stem cells transplantation induced OM patients were recruited. Among these patients, 67 patients received topical mouth rinse and 63 patients received DSIG cream treatment. The OM would be treated on the OM appearance and sustained for 5 days. OM severity was measured daily using The American Oncology Nursing Society recommended Oral Assessment Guideline (OAG) score system. Compared with topical mouth rinse treatment, a significant lower OAG score was observed in DSIG cream treated patients. Specifically, the OAG scores were respectively 12.1 ± 1.1, 12.0 ± 1.2, 11.3 ± 1.3 and 10.4 ± 1.3 from day 2 to day 5 in topical mouth rinse treatment subgroup. Correspondingly, the OAG scores were respectively 10.2 ± 1.0, 9.3 ± 0.9, 8.5 ± 0.6 and 8.0 ± 0.2 for DSIG cream treatment subset (all P < 0.05). Importantly, compared with topical mouth rinse treatment, the DSIG cream significantly shortened OM repair time (4.68 ± 0.98 vs. 8.76 ± 1.80 days, P < 0.001). After 5 days treatment, 54 patients (85.7%) obtained complete regression with an OAG score ≤8, and 7 patients (11.1%) had partial regression with an OAG score of 9-10 in DSIG cream treatment subgroup. However, only 2 patients (3.0%) obtained completed regression and 32 patients (47.8%) had partial regression in topical mouth rinse treatment cohort. Moreover, no serious side-effect was observed in both cohorts. Compared with topical mouth rinse, DSIG cream significantly lowered the OAG score and shortened OM duration.

The objective of the present study is to systematically evaluate and compare the rheological behaviors of body cream and body lotion in actual usage situations. Using a strain-controlled rheometer, the steady shear flow properties of commercially available body cream and body lotion were measured over a wide range of shear rates, and the linear viscoelastic properties of these two materials in small amplitude oscillatory shear flow fields were measured over a broad range of angular frequencies. The temperature dependency of the linear viscoelastic behaviors was additionally investigated over a temperature range most relevant to usual human life. The main findings obtained from this study are summarized as follows: (1) Body cream and body lotion exhibit a finite magnitude of yield stress. This feature is directly related to the primary (initial) skin feel that consumers usually experience during actual usage. (2) Body cream and body lotion exhibit a pronounced shear-thinning behavior. This feature is closely connected with the spreadability when cosmetics are applied onto the human skin. (3) The linear viscoelastic behaviors of body cream and body lotion are dominated by an elastic nature. These solid-like properties become a criterion to assess the selfstorage stability of cosmetic products. (4) A modified form of the Cox-Merz rule provides a good ability to predict the relationship between steady shear flow and dynamic viscoelastic properties for body cream and body lotion. (5) The storage modulus and loss modulus of body cream show a qualitatively similar tendency to gradually decrease with an increase in temperature. In the case of body lotion, with an increase in temperature, the storage modulus is progressively decreased while the loss modulus is slightly increased and then decreased. This information gives us a criterion to judge how the characteristics of cosmetic products are changed by the usual human environments.

Xue, X. H.; Wang, C. B.; Dou, X. K.

2005-08-01

In this study, we use an ice-cream cone model to analyze the geometrical and kinematical properties of the coronal mass ejections (CMEs). Assuming that in the early phase CMEs propagate with near-constant speed and angular width, some useful properties of CMEs, namely the radial speed (v), the angular width (α), and the location at the heliosphere, can be obtained considering the geometrical shapes of a CME as an ice-cream cone. This model is improved by (1) using an ice-cream cone to show the near real configuration of a CME, (2) determining the radial speed via fitting the projected speeds calculated from the height-time relation in different azimuthal angles, (3) not only applying to halo CMEs but also applying to nonhalo CMEs.

In this research, maltodextrin (0, 1 and 2% w/w) and resistant starch (0, 1 and 2% w/w) were used in the formulation of low-fat ice cream (4% fat) and their effects on the physicochemical and sensory properties were investigated. The optimum levels of maltodextrin and resistant starch were determined by response surface methodology. Increment of maltodextrin and resistant starch increased acidity, viscosity, melting rate, time of dripping and overrun but decreased melting rate of ice cream. Results showed that the incorporation of maltodextrin and resistant starch at 0 and 2% w/w respectively, resulted into ice cream with suitable viscosity, melting rate, first dripping time, overrun and acidity.

Cakes were baked with normal ingredients and filled with cream, inoculated with different size enterotoxigenic-staphylococcal inocula. Samples of the cakes were incubated at room temperature and put in the refrigerator. Samples of cake and filling were taken at different times and analyzed for staphylococcal count and presence of enterotoxin. The smaller the inoculum, the longer the time required for sufficient growth (10(6)) to occur for production of detectable enterotoxin. Enterotoxin added to the cake dough before baking (210 degrees C, 45 min) did not survive the baking. The presence of enterotoxin in the contaminated cream filling indicated this as the cause of staphylococcal food poisoning from cream-filled cakes. Refrigeration of the cakes prevented the growth of the staphylococci.

Placebo analgesia is not due to compliance or habituation: EEG and behavioural evidence.

This study was designed to resolve whether experimental placebo responses are due to either increased compliance or habituation. We stimulated both forearms and recorded laser-evoked potentials from 18 healthy volunteers treated on one arm with a sham analgesic cream and an inactive cream on the other (treatment group), and 13 volunteers with an inactive cream on both arms (controls). The treatment group showed a significant reduction in the pain ratings and laser-evoked potentials with both the sham and inactive creams. The control group showed no evidence of habituation to the laser stimulus. The results indicate that the reduction in pain during experimental placebo response is unlikely to be due to sensory habituation or compliance with the experimental instructions.

Monobenzylether of hydroquinone is used worldwide to remove residual pigment in patients with vitiligo universalis. Because of the side effects reported with this drug, the use of monobenzylether of hydroquinone has been restricted in The Netherlands. Our purpose was to evaluate the long-term effectiveness and safety of a combination therapy consisting of topical 4-methoxyphenol (4-MP) cream and Q-switched ruby (QSR) laser in 16 patients with vitiligo universalis. In a retrospective study, patient record forms were evaluated. Data were collected regarding history as well as physical and histologic examination. The patients came to the institute for a follow-up visit after a treatment-free period of 2 to 36 months. Thirteen patients received both therapies. Three patients only used the cream. None of the areas was treated by the cream and QSR laser at the same time. In 11 of the 16 patients (69%; 95% confidence interval [CI], 41%-89%) total depigmentation was achieved using the 4-MP cream. Onset of depigmentation was between 4 and 12 months. Four of the 5 patients who did not respond to the 4-MP cream had successful depigmentation with the QSR laser. Mild burning or itching was reported with the cream in 4 cases (25%). Of the 11 patients who responded to the 4-MP cream, 4 had recurrence of pigmentation (relapse rate of 36%; 95% CI, 11%-69%) after a treatment-free period of 2 to 36 months. In 9 of the 13 patients (69%; 95% CI, 39%-91%) total depigmentation was achieved after QSR laser therapy. Onset of depigmentation was between 7 and 14 days after the treatment. Three of the 4 unresponsive patients showed total depigmentation after application of the 4-MP cream. No side effects were observed. Of the 9 patients who responded to QSR laser therapy, 4 had recurrence of pigmentation (relapse rate of 44%; 95% CI, 14%-79%) after a treatment-free period of 2 to 18 months. These patients had a negative Koebner phenomenon. Depigmentation therapy using a 4-MP cream and/or QSR laser therapy is an effective and safe method to remove disfiguring residual pigment in patients with vitiligo universalis. Patients should be warned that repigmentation may occur, even after total depigmentation has been achieved.

The market sales of premium ice cream have paralleled the growth in consumer desire for rich flavor and taste. Storage temperature is a major consideration in preserving the quality attributes of premium ice cream products for both the manufacturer and retailers during prolonged storage. We investigated the effect of storage temperature (-18℃, -30℃, -50℃, and -70℃) and storage times, up to 52 wk, on the quality attributes of premium ice cream. Quality attributes tested included ice crystal size, air cell size, melting resistance, and color. Ice crystal size increased from 40.3 μm to 100.1 μm after 52 wk of storage at -18℃. When ice cream samples were stored at -50℃ or -70℃, ice crystal size slightly increased from 40.3 μm to 57-58 μm. Initial air cell size increased from 37.1 μm to 87.7 μm after storage at -18℃ for 52 wk. However, for storage temperatures of -50℃ and -70℃, air cell size increased only slightly from 37.1 μm to 46-47 μm. Low storage temperature (-50℃ and -70℃) resulted in better melt resistance and minimized color changes in comparison to high temperature storage (-18℃ and -30℃). In our study, quality changes in premium ice cream were gradually minimized according to decrease in storage temperature up to-50℃. No significant beneficial effect of -70℃ storage was found in quality attributes. In the scope of our experiment, we recommend a storage temperature of -50℃ to preserve the quality attributes of premium ice cream.

Minkin, Mary Jane; Maamari, Ricardo; Reiter, Suzanne

2014-01-01

Postmenopausal vaginal atrophy, resulting from decreased estrogen production, frequently requires treatment. Estrogen preparations provide the most effective treatment; local application is preferred to systemic drugs when treating only vaginal symptoms. As local estrogen therapies have comparable efficacy, this study aimed to understand treatment practices, assess experiences with different forms of local estrogen-delivering applicators, and evaluate satisfaction. Women who were US residents aged ≥18 years, menopausal (no spontaneous menstrual period for ≥1 year or with a double oophorectomy), and receiving local estrogen therapy for 1–6 months (vaginal cream [supplied with a reusable applicator] or vaginal tablets [supplied with a single-use/disposable applicator]), completed an online questionnaire. Data from 200 women (100 cream users and 100 tablet users; mean therapy duration 3.48 months) showed that most stored medication in the room in which it was applied (88%) and applied it at bedtime (71%), a procedure for which cream users required, on average, more than twice the time of tablet users (5.08 minutes versus 2.48 minutes). Many cream users applied larger-than-prescribed amounts of cream, attempting to achieve greater efficacy (42%), or lower-than-recommended doses (45%), most frequently to avoid messiness (33%) or leakage (30%). More tablet users (69%) than cream users (14%) were “extremely satisfied” with their applicator. Postmenopausal women using local estrogen therapy were generally more satisfied with the application of vaginal tablets than cream. Patient satisfaction may help to facilitate accurate dosing. Positive perceptions of medication will help to optimize treatment, which, although not assessed in this study, is likely, in turn, to improve vaginal health. PMID:24648772

Background: Numerous therapeutic options have been tried in the management of melasma. Aims and Objectives: This prospective randomized study was planned to assess the efficacy of low potency triple combination (TC) cream (TC-hydroquinone 2%/tretinoin 0.05%/fluocinolone 0.01%) versus glycolic acid (GA) peels/azelaic acid (AA) 20% cream (GA/AA) combination in melasma. Materials and Methods: Forty patients with melasma were recruited into this study and randomized into two groups. Group A consisting 20 patients received TC cream once a day for night time application for 3 months. Group B comprising of 20 patients received GA/AA 20% cream combination for 3 months. The disease severity was monitored with digital photography, melasma area and severity index (MASI) score, which was calculated at baseline, 6 weeks and 12 weeks, and visual analog scale (VAS) score, which was calculated at baseline and 12 weeks. Results: Of 40 patients, 38 were completed the study. A significant reduction in MASI and VAS was recorded after 6 weeks and 12 weeks of treatment in both groups A and B (P = 0.001). However, there was no significant difference in the mean MASI scores between the two groups at baseline, 6 weeks and 12 weeks. Similarly, there was no difference in the mean VAS scores between the two groups at baseline and 12 weeks. Four patients in group A and 3 in group B experienced adverse effects such as irritation, dryness, and photosensitivity. Conclusion: Both low potency TC cream and GA/AA 20% cream combination are effective in treating melasma among Indian patients. PMID:25814702

This study aims to assess the moisturization in combination or single use (including seven general applications) of three common moisturizers: cream, toner, and spray water. Groups were set as C: cream only; T: toner only; C+T, T+C: cream or toner applied successively within a few minutes; C-T, C-S: cream applied with repeated toner or spray water every 2 h; T-T: toner applied with repeated toner every 2 h; and N: untreated group. Outcomes were the change in skin hydration from baseline at 2, 4, 6, and 8 h after applications. All treated zones displayed a significantly higher degree of hydration compared with the untreated zone ( p < 0.05). For normal skin (hydration value at baseline >35 a.u.), C-T led to greatest hydration change rate compared with others, followed by C+T, T+C, and C. Those three applications exhibited analogous hydration at each test point ( p > 0.05). The hydration rate of C-S differed slightly from T-T, followed by those four mentioned above, with T being the last. For dry skin (hydration value at baseline <35 a.u.), no statistical significance could be detected between C-T zone and C+T, T+C, and C zones ( p > 0.05), the other results were identical. When cream and toner were applied successively, the application order has little effect on skin hydration. The application of cream only was an effective and brief way to achieve favorable moisturization especially for dry skin. As a complement, repeated application of toner rather than spray water is efficacious for skin hydration.

Melasma is a difficult-to-treat hyperpigmentary disorder. While cysteamine is a known potent depigmenting agent, its efficacy in treating melasma has not been tested. To study the efficacy of cysteamine 5% cream in the treatment of patients with epidermal melasma. In this double-blind randomized study, participating patients (n = 50) received either placebo (n = 25) or cysteamine cream (n = 25). Cysteamine cream or placebo were applied on the lesions once a day at bedtime over 4 months. The efficacy of treatments was determined through Mexameter skin colorimetry, Melasma Area Severity Index (MASI) score, Investigator's Global Assessment (IGA) and patients' questionnaires, all performed at baseline and after 2 and 4 months of treatment. At baseline, the mean differences between pigmented and normal skin (calculated by Mexameter) were 75.2 ± 37 and 68.9 ± 31 in the cysteamine and placebo groups, respectively. After 2 and 4 months of application of cysteamine and placebo cream, the mean differences were 39.7 ± 16.6 and 26.2 ± 16 in the cysteamine group, and 63.8 ± 28.6 and 60.7 ± 27.3 in the placebo group, respectively. Statistically significant differences were found between the group outcomes at both points (P = 0.001 and P < 0.001). At the end of the treatment, the MASI scores were significantly lower in the cysteamine group vs. placebo (7.2 ± 5.5 vs. 11.6 ± 7.9, P = 0.02). The IGA and patients' viewpoints indicated significant efficacy of cysteamine cream vs. placebo. Cysteamine cream showed significant efficacy in the treatment of melasma. © 2014 British Association of Dermatologists.

Background Cellulite is a 'cottage cheese-like' cutaneous change caused by subcutaneous fat bulging into the dermis that usually leads to cosmetic problems. Slimming cream containing 3.5% water-soluble caffeine and xanthenes exhibits a lipolytic effect with penetration into the dermis. Objective To evaluate the efficacy and safety of slimming cream for the treatment of cellulite. Methods Fifteen subjects with cellulite applied slimming cream to the thighs and inner side of the upper arms twice daily for 6 weeks. Efficacy was assessed using a standard visual scale, changes in the circumferences of the thighs and upper arms, and patient satisfaction by a questionnaire at baseline, week 3, and week 6. Safety was assessed by inquiring about adverse events through questionnaires. Results The standard visual scale score improved significantly by 0.49 points (19.8%) at week 6. Thigh and upper-arm circumferences decreased by 0.7 cm (1.7%) and 0.8 cm (2.3%), respectively, at week 6. Slight itching and transient flushing were commonly reported, but no serious adverse event occurred. Conclusion The slimming cream tested appears to be effective for the treatment of cellulitis without serious adverse effects. However, additional large clinical trials are required to confirm the efficacy and safety of slimming cream for the treatment of cellulitis. PMID:26082579

Development of a full ice-cream cone model for halo CME structures

2015-04-01

The determination of three dimensional parameters (e.g., radial speed, angular width, source location) of Coronal Mass Ejections (CMEs) is very important for space weather forecast. To estimate these parameters, several cone models based on a flat cone or a shallow ice-cream cone with spherical front have been suggested. In this study, we investigate which cone model is proper for halo CME morphology using 33 CMEs which are identified as halo CMEs by one spacecraft (SOHO or STEREO-A or B) and as limb CMEs by the other ones. From geometrical parameters of these CMEs such as their front curvature, we find that near full ice-cream cone CMEs (28 events) are dominant over shallow ice-cream cone CMEs (5 events). So we develop a new full ice-cream cone model by assuming that a full ice-cream cone consists of many flat cones with different heights and angular widths. This model is carried out by the following steps: (1) construct a cone for given height and angular width, (2) project the cone onto the sky plane, (3) select points comprising the outer boundary, (4) minimize the difference between the estimated projection points with the observed ones. We apply this model to several halo CMEs and compare the results with those from other methods such as a Graduated Cylindrical Shell model and a geometrical triangulation method.

The effects of whey protein addition and transglutaminase treatment, alone and in combination, on the physical and sensory properties of reduced-fat ice cream were investigated. Adding whey protein with or without enzyme treatment decreased melting rate, overrun, and hardness of the reduced-fat ice cream; however, the enzyme-treated sample had a higher melting rate and overrun and softer texture. Whey protein-fortified samples showed higher melting resistance, but lower overrun and firmer texture compared with the enzyme-treated sample without added whey protein. Whey protein addition with or without transglutaminase treatment caused an increase in apparent viscosity and a decrease in flow index of the reduced-fat ice cream; nevertheless, the flow behavior of full-fat sample was most similar to the enzyme-treated reduced-fat sample with no added whey protein. Descriptive sensory analyses showed that neither whey protein addition nor transglutaminase treatment significantly influenced the flavor and odor of reduced-fat ice cream, but they both noticeably improved the color and texture of the final product. The results of this study suggest that whey protein addition with transglutaminase treatment improves the physical and sensory properties of reduced-fat ice cream more favorably than does whey protein addition or transglutaminase treatment alone.

Objective: To make a comparison between terbinafine 1% cream and ketoconazole 2% cream in the treatment of pityriasis versicolor. Methods: This randomized single blind study included 110 patients with clinical diagnosis of pityriasis versicolor and positive mycological test for Malassezia furfur. The patients were randomly assigned to two groups. Group 1 used terbinafine cream and group 2 applied ketoconazole cream on the skin lesions for two weeks. Each group consisted of 55 patients. Clinical and mycological examinations were performed at baseline, at the end of the 2nd, 4th and 8th week of starting the treatment regimens. Results: At the end of the 2nd week we achieved cure rates of 72% and 64.3% for group 1 and group 2 respectively. At the end of the 4th week the respective cure rates for group 1 and group 2 were 81.2% and 69%, and at the end of the 8th week 70.8% of the patients in group 1 and 61.9% of the patients in group 2 were cured. Conclusion: The results of this study showed no significant statistical differences between the two groups in regard to cure and recurrence rates. But the numbers of cured patients were higher and recurrent cases were lower in group 1. PMID:25674122

Tinea cruris, a pruritic superficial fungal infection of the groin, is the second most common clinical presentation for dermatophytosis. This phase 3 study evaluated the safety and efficacy of topical luliconazole cream 1% in patients with tinea cruris. 483 patients were enrolled and 256 male and female patients aged ≥12 years with clinically evident tinea cruris and eligible for modified intent-to-treat analysis were randomized 2:1 to receive luliconazole cream 1% (n=165) or vehicle (n=91) once daily for 7 days. Efficacy was evaluated at baseline and at days 7, 14, 21, and 28 based on mycology (potassium hydroxide, fungal culture) and clinical signs (erythema, scaling, pruritus). The primary outcome was complete clearance at day 28 (21 days posttreatment). Safety evaluations included adverse events and laboratory assessments. Complete clearance was obtained in 21.2% (35/165) of patients treated with luliconazole cream 1% compared with 4.4% (4/91) treated with vehicle (P<0.001). The safety profile of luliconazole cream 1% was similar to vehicle. The study was conducted under controlled conditions in a relatively small population. Luliconazole cream 1% applied once daily for 7 days is more effective than vehicle and well tolerated in patients with tinea cruris.

The study aimed to evaluate the effects of two different sheep milk-based food matrices - fermented sheep milk and ice cream - with added probiotic bacteria (Lactobacillus casei 431) on dental enamel subjected to an in vitro highly cariogenic challenge. Sixty enamel blocks were selected and randomly allocated into five treatment groups (n=12): conventional fermented sheep milk (CFSM), probiotic fermented sheep milk (PFSM), conventional sheep milk ice cream (CSMIC), probiotic sheep milk ice cream (PSMIC) and control using deionized water. The blocks were subjected to highly cariogenic pH cycling and the products were applied (5min), in a blinded way, once a day to simulate a daily use for 8 consecutive days. A microhardness test was performed before and after the treatment to estimate the percentage of microhardness surface loss (% SML). Scanning electronic microscopy (SEM) was performed to confirm the mineral loss. All groups had lost microhardness after the experiment. However, CFSM and PFSM exhibited the most positive findings when compared to the control in both ice creams. Scanning electron microscopy showed less mineral loss in CFSM and PFSM compared with CSMIC, PSMIC and control after the cariogenic challenge. Overall, fermented milk decreased mineral loss from enamel subjected to a highly cariogenic challenge, regardless of the presence of probiotics in their composition, which had a higher efficacy compared to ice cream.

Effect of Zataria multiflora on bacterial vaginosis and Trichomonas vaginalis is shown in vivo and in vitro. We compare the effectiveness of Zataria multiflora cream and oral metronidazole pill on results of treatment for vaginal infections including Trichomonas and bacterial vaginosis; these infections occur simultaneously. The study included 420 women with bacterial vaginosis, Trichomonas vaginalis, or both infections together, who were randomly divided into six groups. Criteria for diagnosis were wet smear and Gram stain. Vaginal Zataria multiflora cream and placebo pill were administered to the experiment groups; the control group received oral metronidazole pill and vaginal placebo cream. Comparison of the clinical symptoms showed no significant difference in all three vaginitis groups receiving metronidazole pill and vaginal Zataria multiflora cream. However, comparison of the wet smear test results was significant in patients with trichomoniasis and bacterial vaginosis associated with trichomoniasis in the two treatment groups (p = 0.001 and p = 0.01). Vaginal Zataria multiflora cream had the same effect of oral metronidazole tablets in improving clinical symptoms of all three vaginitis groups, as well as the treatment for bacterial vaginosis. It can be used as a drug for treatment of bacterial vaginosis and elimination of clinical symptoms of Trichomonas vaginitis. PMID:26266260

The human immunodeficiency virus epidemic affects millions of people worldwide. As women are more vulnerable to infection, female-controlled interventions can help control the spread of the disease significantly. Glycerol monolaurate (GML), an inexpensive and safe compound, has been shown to protect against simian immunodeficiency virus infection when applied vaginally. However, on account of its low aqueous solubility, fabrication of high-dose formulations of GML has proven difficult. We describe the development of a vaginal cream that could be loaded with up to 35% GML. Vaginal drug levels and safety of 3 formulations containing increasing concentrations of GML (5%w/w, 15%w/w, and 35%w/w) were tested in rhesus macaques after vaginal administration. GML concentration in the vaginal tissue increased as the drug concentration in the cream increased, with 35% GML cream resulting in tissue concentration of ∼0.5 mg/g, albeit with high interindividual variability. Compared with the vehicle control, none of the GML creams had any significant effect on the vaginal flora and cytokine (macrophage inflammatory protein 3α and interleukin 8) levels, suggesting that high-dose GML formulations do not induce local adverse effects. In summary, we describe the development of a highly loaded vaginal cream of GML, and vaginal drug levels and safety after local administration in macaques.

A study of the microbiological quality of ice lice creams/sorbets sold on the streets of Phnom Penh city was conducted from April 1996 to April 1997. Socio-demographic and environmental characteristics with two ice/ice creams samples were collected from vendors selected in the city. A total of 105 vendors and 210 ice/ice creams samples were randomly selected for the study period. Ice/ice cream vendors in the streets of Phnom Penh were adults (mean age: 28 years old) with a male predominance (86.5%). Mean educational level of vendors was 5 years with no training in mass catering. Most ice creams and sorbets (81.7%) were made using traditional methods. Microbiological analysis performed in the laboratory of Pasteur Institute of Cambodia indicated the poor bacteriological quality of the samples. The proportions of samples classified unsafe according to microbiological criteria were 83.3% for total bacterial count at 30 degrees C, 70% for total coliforms, 30% for faecal coliforms, 12.2% for Staphylococcus aureus and 1.9% for presence of Salmonella spp. These bacterial results suggest that many other food products sold in the streets may be similarly poor. Safety measures should be undertaken to avoid potential threats. Regulation of the street food sector should be part of a larger strategy for enhanced food safety and environmental quality in the city.

The exposure to ultraviolet radiations (UVR) is the key source of skin sunburn; it may produce harmful entities, reactive oxygen species (ROS), leading to aging. The skin can be treated and protected from the injurious effects of ROS by using various pharmaceutical formulations, such as cream. Cream can be loaded with antioxidants to quench ROS leading to photo-protective effects. Moreover, modern medicines depend on ethnobotanicals for protection or treatment of human diseases. This review article summarizes various in vivo antioxidant studies on herbal creams loaded with phyto-extracts. These formulations may serve as cosmeceuticals to protect skin against injurious effects of UVR. The botanicals studied for dermatologic use in cream form include Acacia nilotica, Benincasa hispida, Calendula officinalis, Camellia sinensis, Camellia sinensis, Nelumbo nucifera, Capparis decidua, Castanea sativa, Coffea arabica, Crocus sativus, Emblica officinalis Gaertn, Foeniculum vulgare, Hippophae rhamnoides, Lithospermum erythrorhizon, Malus domestica, Matricaria chamomilla L., Moringa oleifera, Morus alba, Ocimum basilicum, Oryza sativa, Polygonum minus, Punica granatum, Silybum marianum, Tagetes erecta Linn., Terminalia chebula, Trigonella foenum-graecum, and Vitis vinifera. The observed anti-aging effects of cream formulations could be an outcome of a coordinating action of multiple constituents. Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed. PMID:26448818

Proper management of waste streams and residues from agro-industry is very important to prevent environmental pollution. In particular, the anaerobic co-digestion process can be used as an important tool for safe disposal and energy recovery from agro-industry waste streams and residues. The primary objective of this laboratory-scale study was to determine whether it was possible to recover energy (biogas) from ice-cream production residues and wastewater, through a mesophilic anaerobic co-digestion process. A high methane yield of 0.338 L CH4/gCOD(removed) could be achieved from anaerobic digestion of ice-cream wastewater alone, with almost 70% of methane in biogas, while anaerobic digestion of ice-cream production residue alone did not seem feasible. When wastewater and ice-cream production residue were anaerobically co-digested at a ratio of 9:1 by weight, the highest methane yield of 0.131 L CH4/gCOD(removed) was observed. Buffering capacity seemed to be imperative in energy recovery from these substrates in the anaerobic digestion process.

Effects of Green Banana Flour on the Physical, Chemical and Sensory Properties of Ice Cream.

PubMed

Yangılar, Filiz

2015-09-01

In the present study, possible effects of the addition of banana flour at different mass fractions (1 and 2%) are investigated on physical (overrun, viscosity), chemical (dry matter, fat and ash content, acidity, pH, water and oil holding capacity and colour), mineral content (Ca, K, Na, P, S, Mg, Fe, Mn, Zn and Ni) and sensory properties of ice cream. Fibre--rich banana pieces were found to contain 66.8 g per 100 g of total dietary fibre, 58.6 g per 100 g of which were insoluble dietary fibre, while 8.2 g per 100 g were soluble dietary fibre. It can be concluded from these results that banana is a valuable dietary fibre source which can be used in food production. Flour obtained from green banana pulp and peel was found to have significant (p<0.05) effect on the chemical composition of ice creams. Sulphur content increased while calcium content decreased in ice cream depending on banana flour content. Sensory results indicated that ice cream sample containing 2% of green banana pulp flour received the highest score from panellists.

The effects of application of ultrasonic waves to recombined milk emulsions (3.5% fat, 7% total solids) and raw milk on fat destabilization and creaming were examined. Coarse and fine recombined emulsions (D[4,3]=9.3 μm and 2.7 μm, respectively) and raw milk (D[4,3]=4.9 μm) were subjected to ultrasound for 5 min at 35°C and 400 kHz or 1.6 MHz (using a single transducer) or 400 kHz (where the emulsion was sandwiched between two transducers). Creaming, as calculated from Turbiscan measurements, was more evident in the coarse recombined emulsion and raw milk compared to that of the recombined fine emulsion. Micrographs confirmed that there was flocculation and coalescence in creamed layer of emulsion. Coalescence was confirmed by particle size measurement. These results imply that ultrasound has potential to pre-dispose fat particles in milk emulsions to creaming in standing wave systems and in systems with inhomogeneous sound distributions.

2012-09-01

The aims of this study were (1) to map sensory attributes of vanilla ice cream with reduced fat and sugar, and (2) to determine drivers of liking by applying external preference mapping and reveal the relationship between descriptive attributes and hedonic judgments using the partial least squares method. Descriptive sensory profiles (n=11) and consumer test (n=117) of 6 samples of vanilla ice cream (3 traditional and 3 with reduced fat and sugar) were determined. The attributes brightness and sweet aftertaste for sample and creaminess (appearance and texture) and sweet aroma contributed positively to the acceptance of ice cream samples. The attributes aeration, powdered milk aroma and flavor, and white chocolate aroma and flavor contributed positively to the acceptance of the ice creams. The attributes hydrogenated fat aroma and flavor were responsible for the lower acceptance of samples. The reduction in fat and sugar did not necessarily cause a decrease in acceptance. The most important factors were selection of the appropriate sweetener system and the use of good quality raw material. Copyright © 2012 American Dairy Science Association. Published by Elsevier Inc.

Mercury, hydroquinone and clobetasol propionate in skin lightening products in West Africa and Canada.

PubMed

Gbetoh, Mètogbé Honoré; Amyot, Marc

2016-10-01

Skin lightening products are types of cosmetics (creams, gels, lotions and soaps) applied voluntarily on skin. Several of these products contain a variety of active ingredients that are highly toxic. Among those toxic agents, the present study focuses on mercury, hydroquinone, and clobetasol propionate. Out of the 93 lightening soaps and 98 creams purchased in large city markets in sub-Saharan West Africa and in small ethnic shops in Canada, 68-84% of all creams and 7.5-65% of all soaps exceeded regulatory guidelines for at least one active ingredient when considering different regulations. Mercury was found in high concentrations mainly in soaps, while hydroquinone and clobetasol propionate concentrations exceeded US FDA standards in some creams for all countries included in our study. Concentrations of the three compounds declared on labels of soaps and creams usually did not correspond to concentrations actually measured, particularly for mercury and hydroquinone. Overall, our results indicate that most studied skin-lightening products are potentially toxic and that product labels are frequently inaccurate with respect to the presence of toxic agents.

The effects of the gastric pentadecapeptide BPC 157 were investigated when administered topically or systemically in burned mice. This agent is known to have a beneficial effect in a variety of models of gastrointestinal lesions, as well as on wound or fracture healing. Deep partial skin thickness burns (1.5x1.5 cm) covering 20% of total body area, were induced under anesthesia on the back of mice by controlled burning and gastric lesions were assessed 1, 2, 3, 7, 14 and 21 days following injury. The first application of BPC 157 was immediately following burning, and thereafter, once daily, until 24 h before sacrifice. In the initial experiments, exposure to direct flame for 5 s, the BPC 157 was applied at 10 microg or 10 ng/kg b.w. intraperitoneally (i.p.) by injection or alternatively, topically, at the burn, as a thin layer of cream (50 microg of BPC 157 dissolved in 2 ml of distilled water was mixed with 50 g of commercial neutral cream (also used as local vehicle-control)), while silver sulfadiazine 1% cream was a standard agent acting locally. Others received no local medication: they were treated i.p. by injection of distilled water (distilled water-control) or left without any medication (control). In subsequent experiments involving deeper burns (direct flame for 7 s), BPC 157 creams (50 microg, 5 microg, 500 ng, 50 ng or 5 ng of BPC 157 dissolved in 2 ml of distilled water was mixed with 50 g of commercial neutral cream), or vehicle as a thin layer of cream, were applied topically, at the burn. Compared with untreated controls, in both experiments, in the BPC 157 cream-treated mice all parameters of burn healing were improved throughout the experiment: less edema was observed and inflammatory cell numbers decreased. Less necrosis was seen with an increased number of capillaries along with an advanced formation of dermal reticulin and collagen fibers. An increased number of preserved follicles were observed. Two weeks after injury, BPC 157 cream-treated mice completely reversed the otherwise poor re-epithelization ratio noted in the untreated control or mice treated with vehicle only. Tensiometry investigation showed an increased breaking strength and relative elongation of burned skin, while water content in burned skin decreased. This was, however, not the case with the vehicle or silver sulfadiazine. Relative to the control values, in silver sulfadiazine cream-treated mice, only collagen fiber formation was increased, in addition to a decreased inflammatory cell number. Relative to control values, BPC 157 given i.p. decreased the number of inflammatory cells, lowered water content in burned skin, and raised breaking strength and relative elongation of burned skin during tensiometry. Through the experimental period, gastric lesions were continuously noted in all thermally injured mice left without local medication and they were consistently attenuated only by BPC 157 treatments: either given i.p. (at either dose), or given locally (at either concentration). Other treatments (i.e. local treatment with silver sulfadiazine cream or neutral cream in mice subjected for 5 s to direct flame), led to only poor, if any attenuation. This stable gastric pentadecapeptide appears to be active and gives a stimulation to burn healing at the defect site. The agent may act by causing an upregulation of the growth factors, as well as influencing other local factors.

2017-01-01

Oral magnesium supplementation is commonly used to support a low magnesium diet. This investigation set out to determine whether magnesium in a cream could be absorbed transdermally in humans to improve magnesium status. In this single blind, parallel designed pilot study, n = 25 participants (aged 34.3+/-14.8y, height 171.5+/-11cm, weight 75.9 +/-14 Kg) were randomly assigned to either a 56mg/day magnesium cream or placebo cream group for two weeks. Magnesium serum and 24hour urinary excretion were measured at baseline and at 14 days intervention. Food diaries were recorded for 8 days during this period. Mg test and placebo groups' serum and urinary Mg did not differ at baseline. After the Mg2+ cream intervention there was a clinically relevant increase in serum magnesium (0.82 to 0.89 mmol/l,p = 0.29) that was not seen in the placebo group (0.77 to 0.79 mmol/L), but was only statistically significant (p = 0.02)) in a subgroup of non-athletes. Magnesium urinary excretion increased from baseline slightly in the Mg2+ group but with no statistical significance (p = 0.48). The Mg2+ group showed an 8.54% increase in serum Mg2+ and a 9.1% increase in urinary Mg2+ while these figures for the placebo group were smaller, i.e. +2.6% for serum Mg2+ and -32% for urinary Mg2+. In the placebo group, both serum and urine concentrations showed no statistically significant change after the application of the placebo cream. No previous studies have looked at transdermal absorbency of Mg2+ in human subjects. In this pilot study, transdermal delivery of 56 mg Mg/day (a low dose compared with commercial transdermal Mg2+ products available) showed a larger percentage rise in both serum and urinary markers from pre to post intervention compared with subjects using the placebo cream, but statistical significance was achieved only for serum Mg2+ in a subgroup of non-athletes. Future studies should look at higher dosage of magnesium cream for longer durations. ISRCTN registry ID No. ISRTN15136969.

Vaginal dryness and associated symptoms may occur in women of any age and are a frequent burden after menopause. The North American Menopause Society recommends long-acting non-hormonal vaginal creams as first-line therapy. A new type of such creams was developed (Remifemin® FeuchtCreme in Austria and Germany). This hormone-free cream contains hamamelis virginiana distillate and well-established vaginal cream ingredients. We explored its physical function and tolerability in an open interventional clinical trial. 20 postmenopausal women (54 to 76 years, median 60) treated their vaginal dryness using this cream once daily for 7 days and reported about their symptoms before, 4 to 8 h after first and 14 to 22 h after last application. A physician assessed tolerability and local physical function. All patients completed the study. Local physical function significantly improved from dryness at baseline (mean 4.0 ± SD 1.8) to a normal moisture level, on average (6.3 ± 2.1 after first, 6.7 ± 2.1 after last application, p = 0.0001). Subjective assessment of a feeling vaginal dryness showed a significant improvement at both times (p = 0.0001). Onset and duration of feeling moisturized were reported to be 0 to 2 min and 11.3 ± 6.9 h after application. All women reported vaginal dryness at baseline. 55 and 80% of patients reported no dryness after first application and at the end of the investigation. The cream was seen at the application site for up to 21 h. Tolerability assessments did not reveal any relevant change over time. There were four adverse events in 4 patients, all not serious and of mild intensity: urinary urgency (2), diarrhoea (1) and mild spotting after first application (1). The latter was caused by the dry surface of the applicator and was avoided by moisturizing the surface of the applicator at subsequent applications. In conclusion, these study results indicate a well-tolerated and long-acting function of this new vaginal moisturizing cream. Further clinical research in more patients will follow.

Moisturisers prevent and treat dry skin. They can also protect sensitive skin, improve skin tone and texture, and mask imperfections. Herbal medicines or their extracts have been available as topical formulations and cosmetics. Arctium lappa L. (Asteraceae) has been used to treat inflammatory disorders and various skin problems. It could be a candidate herbal medicine for treating dry skin condition.This study aims to establish the efficacy and safety of a proposed herbal moisturising cream containing Arctium lappa L. seed extract, which has been approved by the Korean Ministry of Food and Drug Safety for use in cosmetics. This study is a randomised, double-blind, placebo-controlled study with two parallel groups (proposed herbal moisturising cream vs. placebo cream). We will recruit 66 healthy male and female participants, aged 20 to 65 years, who have been diagnosed with dry skin conditions. Participants will be randomly allocated to receive either the proposed herbal moisturising cream or a placebo cream for four weeks. Each participant will be examined for signs and symptoms before and after using the cream. Skin hydration, sebum (oily secretion) levels and transepidermal water loss (TEWL; constitutive loss of water from the skin surface) will be assessed. Participants will also be asked to fill out a health-related quality of life questionnaire. Safety will be assessed using blood tests, urine analysis, a pregnancy test, and the assessment of vital signs. This trial will utilise high-quality methodologies in accordance with both consolidated standards for reporting trials guidelines and the guidelines for clinical trials of cosmetics products that are aimed at expressions and advertisement approval in Korea. It will evaluate the clinical efficacy and safety of a proposed herbal moisturising cream containing Arctium lappa L. seed extract to treat dry skin conditions and provide itch relief. Moreover, we will also employ health-related quality of life questionnaires to assess changes in the quality of life. The results of this study will be used to present the evidence needed to request advertising/display allowances, in compliance with the recently amended Cosmetics Act for advertisement in Korea.

The use of the mandibular infiltration anesthetic technique in adults.

PubMed

Meechan, John G

2011-09-01

The author describes the use of the infiltration anesthetic technique to anesthetize mandibular teeth in adults and explores its mechanism of action. The author reviewed articles describing randomized controlled trials of the mandibular infiltration anesthetic technique in healthy participants. The author found that using the mandibular infiltration anesthetic technique can produce anesthesia in adult mandibular teeth. The success was dose dependent and the choice of anesthetic solution was significant; 4 percent articaine with 1:100,000 epinephrine was more effective than 2 percent lidocaine with 1:100,000 epinephrine. Combining buccal and lingual infiltrations increased success in the mandibular incisor region. The success of the mechanism of infiltration of anesthetic at the mandibular first molar appeared to depend on the mental foramen. The mandibular infiltration anesthetic technique is an effective method of anesthetizing mandibular incisors. Four percent articaine with epinephrine appears to be the preferred solution. The choice of anesthetic solution is important when using the infiltration anesthetic technique in the adult mandible.

Naltrexone (NTX) is a long-acting opiate antagonist. Low-dose naltrexone (LDN) therapy has shown promising results in the treatment of several autoimmune disorders. Our aim was to formulate NTX into a cream for the delivery of LDN and develop an analytical technique for the quantification of NTX and its active metabolite 6-β-naltrexol (NTXol) during transdermal diffusion cell permeation studies. A 1% w/w NTX cream was formulated and drug permeation was examined over 24 h using static Franz diffusion cells mounted with pig skin. A Liquid Chromatography Quadrupole-Time of Flight Mass Spectrometry (LC-MS Q-ToF) method was developed for the detection of NTX and NTXol in the receptor solution, skin membrane and residual cream on the donor chamber after completion of the diffusion studies. The cream formulation exhibited steady state release of NTX over 24 h after an initial lag time of 2.74 h. The bioconversion of NTX to NTXol in the skin membrane was 1.1%. It was concluded that the cream may be an effective formulation for the sustained transdermal delivery of LDN. The novel LC Q-ToF MS method allowed the accurate measurement of NTX and NTXol levels across the diffusion cell assemblies and the quantification of NTX metabolism in the skin.

The role of home-made ice cream as a vehicle of Salmonella enteritidis phage type 4 infection from fresh shell eggs.

Morgan, D.; Mawer, S. L.; Harman, P. L.

A family outbreak of Salmonella enteritidis PT4 infection is described in which home-made ice cream was identified as the vehicle of infection. The ice cream contained approximately 10(5) S. enteritidis PT4 organisms per gm and was probably contaminated by an infected shell egg containing between 10(5)-10(8) organisms. The continued relevance of the Chief Medical Officer's warning on the use of raw shell eggs is highlighted. Home-made ice cream using the same recipe as ice cream that had been incriminated as the cause of the family outbreak of S. enteritidis PT4 infection was used to study the growth of the organism that might have occurred in the 3-4 h it took to prepare the product. When the inoculum was in the stationary phase, as it would be from shell or other cross contamination, there was a lag phase of 3 h before growth occurred at room temperature. Even when actively multiplying organisms were introduced, as may be found in an infected egg, there was less than 3 log(10) increase in the salmonella count in 4 h at room temperature. It was, therefore, given the high S. enteritidis count, unlikely that the ice cream was cross-contaminated. By contrast, raspberry sorbet at pH 3.73 proved to be lethal to a large inoculum of S. enteritidis and may be a relatively safe raw egg containing product. PMID:8062876

Purpose Palmar-plantar erythrodysethesia (PPE) is a common chemotherapy and anti-VEGF multi-kinase inhibitor class-related toxicity that often results in debilitating skin changes and often limits the use of active anti-cancer regimens. Mechanistic and anecdotal clinical evidence suggested that topical application of sildenafil cream may help reduce the severity of PPE. Therefore, we conducted a randomized, double-blind, placebo-controlled pilot study to evaluate the feasibility, safety and efficacy of topical sildenafil cream for the treatment of PPE. Methods Eligible subjects were required to have grade 1–3 PPE associated with either capecitabine or sunitinib. Subjects were randomized to receive 1% topical sildenafil cream to the left extremities or right extremities and placebo cream on the opposite extremity. 0.5 mL of cream was applied to each affected hand/foot two times per day. The primary endpoint was improvement in PPE grading at any point on study. Clinical assessments were evaluated by NCI-CTC 4.0 grading and patient self-reported pain. Results Ten subjects were enrolled; 9 were evaluable for safety and efficacy. Five of nine subjects reported some improvement in foot pain and 3 of 8 subjects for hand pain improvement. One of these subjects noted specific improvement in tactile function. No treatment-related toxicities were observed. Conclusions In this limited, single center study, topical cream containing 1% sildenafil is feasible to administer, is well-tolerated, and may mitigate PPE-related symptoms due to anti-cancer therapeutic agents. Further validation is necessary. PMID:25341548

Facial hirsutism is a cosmetic concern for women and can lead to significant anxiety and lack of self-esteem. Eflornithine cream is indicated for the treatment of facial hirsutism. However, limited success rate and overall patient's satisfaction, even with a long-term and high-frequency application, leave room for improvement. The objective of this study is to test the effect of microneedle treatment on the in vitro skin permeation and the in vivo efficacy of eflornithine cream in a mouse model. In vitro permeation study of eflornithine was performed using Franz diffusion cell. In vivo efficacy study was performed in a mouse model by monitoring the re-growth of hair in the lower dorsal skin of mice after the eflornithine cream was applied onto an area pretreated with microneedles. The skin and the hair follicles in the treated area were also examined histologically. The hair growth inhibitory activity of eflornithine was significantly enhanced when the eflornithine cream was applied onto a mouse skin area pretreated with microneedles, most likely because the micropores created by microneedles allowed the permeation of eflornithine into the skin, as confirmed in an in vitro permeation study. Immunohistochemistry data revealed that cell proliferation in the skin and hair follicles was also significantly inhibited when the eflornithine cream was applied onto a skin area pretreated with microneedles. The integration of microneedle treatment into topical eflornithine therapy represents a potentially viable approach to increase eflornithine's ability to inhibit hair growth.

Omega-3 fatty acids and oxidative stability of ice cream supplemented with olein fraction of chia (Salvia hispanica L.) oil.

2017-02-07

Chia (Salvia hispanica L.) has been regarded as good source of polyunsaturated omega-3 fatty acids with cardiac, hepatic, hypotensive, antiallergic and antidiabetic role. Concentration of omega-3 fatty acids in chia oil can be enhanced by fractionation. Olein/low melting fraction of chia oil has higher concentration of omega-3 fatty acids. Therefore, main objective of current investigation was determination of various concentration effect of olein fraction of chia oil on omega-3 fatty acids, oxidative stability and sensory characteristics of ice cream. Ice cream samples were prepared by partially replacing the milk fat with olein fraction of chia oil at 5, 10, 15 and 20% concentrations (T 1 , T 2 , T 3 and T 4 ), respectively. Ice cream prepared from 100% milk fat was kept as control. Ice cream samples stored at -18 °C for 60 days were analysed at 0, 30 and 60 days of the storage period. Fatty acid profile, total phenolic contents, total flavonoids, free fatty acids, peroxide value, anisidine value and sensory characteristics of ice cream samples was studied. Concentration of α-linolenic acid, eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid in T 4 was 13.24, 0.58, 0.42 and 0.31%, respectively. Total phenolic contents of control, T 1 , T 2 , T 3 and T 4 were recorded 0.12, 1.65, 3.17, 5.19 and 7.48 mg GAE/mL, respectively. Total flavonoid content of control, T 1 , T 2 , T 3 and T 4 were found 0.08, 0.64, 1.87, 3.16 and 4.29 mg Quercetin Equivalent/mL. 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity of control, T 1 , T 2 , T 3 and T 4 was noted 5.61, 17.43, 36.84, 51.17 and 74.91%, respectively. After 60 days of storage period, the highest peroxide value of 1.84 (MeqO 2 /kg) was observed in T 4 , which was much less than allowable limit of 10 (MeqO 2 /kg). Flavour score was non-significant after 30 days of storage period. Supplementation of ice cream with olein fraction of chia oil enhanced the concentration of omega-3 fatty acids and improved the antioxidant perspectives of ice cream. These results suggest that omega-3 fatty acids and antioxidant characteristics of ice cream may be improved with olein fraction of chia oil for discerning consumers.

To investigate patient acceptability, efficacy, and skin biophysiological effects of a cream/cleanser combination for childhood atopic dermatitis. Paediatric dermatology clinic at a university teaching hospital in Hong Kong. Consecutive paediatric patients with atopic dermatitis who were interested in trying a new moisturiser were recruited between 1 April 2013 and 31 March 2014. Swabs and cultures from the right antecubital fossa and the worst eczematous area, disease severity (SCORing Atopic Dermatitis index), skin hydration, and transepidermal water loss were obtained prior to and following 4-week usage of a cream/cleanser containing lipid complex with shea butter extract (Ezerra cream; Hoe Pharma, Petaling Jaya, Malaysia). Global or general acceptability of treatment was documented as 'very good', 'good', 'fair', or 'poor'. A total of 34 patients with atopic dermatitis were recruited; 74% reported 'very good' or 'good', whereas 26% reported 'fair' or 'poor' general acceptability of treatment of the Ezerra cream; and 76% reported 'very good' or 'good', whereas 24% reported 'fair' or 'poor' general acceptability of treatment of the Ezerra cleanser. There were no intergroup differences in pre-usage clinical parameters of age, objective SCORing Atopic Dermatitis index, pruritus, sleep loss, skin hydration, transepidermal water loss, topical corticosteroid usage, oral antihistamine usage, or general acceptability of treatment of the prior emollient. Following use of the Ezerra cream, mean pruritus score decreased from 6.7 to 6.0 (P=0.036) and mean Children's Dermatology Life Quality Index improved from 10.0 to 8.0 (P=0.021) in the 'very good'/'good' group. There were no statistically significant differences in the acceptability of wash (P=0.526) and emollients (P=0.537) with pre-trial products. When compared with the data of another ceramide-precursor moisturiser in a previous study, there was no statistical difference in efficacy and acceptability between the two products. The trial cream was acceptable in three quarters of patients with atopic dermatitis. Patients who accepted the cream had less pruritus and improved quality of life than the non-accepting patients following its usage. The cream containing shea butter extract did not differ in acceptability or efficacy from a ceramide-precursor product. Patient acceptability is an important factor for treatment efficacy. There is a general lack of published clinical trials to document the efficacy and skin biophysiological effects of many of the proprietary moisturisers.

Background. Skin infections occur commonly and often present therapeutic challenges to practitioners due to the growing concerns regarding multidrug-resistant bacterial, viral, and fungal strains. The antimicrobial properties of zinc sulfate and copper sulfate are well known and have been investigated for many years. However, the synergistic activity between these two metal ions as antimicrobial ingredients has not been evaluated in topical formulations. Objective. The aims of the present study were to (1) formulate topical creams and gels containing zinc and copper alone or in combination and (2) evaluate the in vitro antibacterial activity of these metal ions in the formulations. Method. Formulation of the gels and creams was followed by evaluating their organoleptic characteristics, physicochemical properties, and in vitro antibacterial activity against Escherichia coli and Staphylococcus aureus. Results. Zinc sulfate and copper sulfate had a strong synergistic antibacterial activity in the creams and gels. The minimum effective concentration was found to be 3 w/w% for both active ingredients against the two tested microorganisms. Conclusions. This study evaluated and confirmed the synergistic in vitro antibacterial effect of copper sulfate and zinc sulfate in a cream and two gels. PMID:27885352

Striae are linear depressions of the skin and causes psychological and sexual problems in person. Different methods are used to prevent and treat them but there is no definitive method. We compared the effect of Aloe vera gel and sweet almond oil on striae gravidarum. In this double-blind clinical trial, 160 nulliparous women were enrolled and randomly divided into three case groups and one control group. The four groups were given 700 g Aloe vera, sweet almond oil, and base cream to use topically on the abdominal skin and forth group don't receive any medication as control group in five steps, they were examined study's variables (itching, erythema, and spread of striae) using statistical tests in SPSS. The findings showed that Aloe vera and sweet almond oil creams are more effective than the base cream and the control group to decrease itching and erythema and to prevent the spread of striae on the surface of abdomen (p < .05); however, all three creams had a similar effect on the diameter and the number of striae (p > .05). Aloe vera and sweet almond oil creams reduce the itching of striae and prevent their progression.

Twenty-two patients with severe or recalcitrant rosacea were divided into three treatment groups in a randomized, double-blind trial that compared low-dose oral isotretinoin (10 mg/d), topically applied tretinoin (0.025% cream), and the combined use of both isotretinoin and tretinoin. For the first 16 weeks of the trial, subjects received one of these three trial regimens. For the final 16 weeks, isotretinoin was withheld while tretinoin cream or a placebo cream was continued. Twenty subjects completed the trial. Each treatment produced therapeutic benefits with regard to the number of papules and pustules and erythema. Treatment with oral isotretinoin appeared to give a more rapid onset of improvement, but there were no differences between the groups after 16 weeks. This level of improvement continued during the succeeding 16 weeks of observation whether the subjects used the tretinoin or the placebo cream. Adverse events were minimal and well tolerated in all groups. Low-dose oral isotretinoin and topical tretinoin cream therapy appear to be beneficial in the treatment of severe or recalcitrant rosacea. No additive benefit is noted with the combined use of these two modalities.

Creaming and Parking in Quasi-Marketised Welfare-to-Work Schemes: Designed Out Of or Designed In to the UK Work Programme?

PubMed

Carter, Eleanor; Whitworth, Adam

2015-04-01

'Creaming' and 'parking' are endemic concerns within quasi-marketised welfare-to-work (WTW) systems internationally, and the UK's flagship Work Programme for the long-term unemployed is something of an international pioneer of WTW delivery, based on outsourcing, payment by results and provider flexibility. In the Work Programme design, providers' incentives to 'cream' and 'park' differently positioned claimants are intended to be mitigated through the existence of nine payment groups (based on claimants' prior benefit type) into which different claimants are allocated and across which job outcome payments for providers differ. Evaluation evidence suggests however that 'creaming' and 'parking' practices remain common. This paper offers original quantitative insights into the extent of claimant variation within these payment groups, which, contrary to the government's intention, seem more likely to design in rather than design out 'creaming' and 'parking'. In response, a statistical approach to differential payment setting is explored and is shown to be a viable and more effective way to design a set of alternative and empirically grounded payment groups, offering greater predictive power and value-for-money than is the case in the current Work Programme design.

Effects of Green Banana Flour on the Physical, Chemical and Sensory Properties of Ice Cream

PubMed Central

2015-01-01

Summary In the present study, possible effects of the addition of banana flour at different mass fractions (1 and 2%) are investigated on physical (overrun, viscosity), chemical (dry matter, fat and ash content, acidity, pH, water and oil holding capacity and colour), mineral content (Ca, K, Na, P, S, Mg, Fe, Mn, Zn and Ni) and sensory properties of ice cream. Fibre--rich banana pieces were found to contain 66.8 g per 100 g of total dietary fibre, 58.6 g per 100 g of which were insoluble dietary fibre, while 8.2 g per 100 g were soluble dietary fibre. It can be concluded from these results that banana is a valuable dietary fibre source which can be used in food production. Flour obtained from green banana pulp and peel was found to have significant (p<0.05) effect on the chemical composition of ice creams. Sulphur content increased while calcium content decreased in ice cream depending on banana flour content. Sensory results indicated that ice cream sample containing 2% of green banana pulp flour received the highest score from panellists. PMID:27904363

Trace amounts of potentially toxic metals can be either intentionally added to cosmetics or present as impurities in the raw materials. In the present study, the levels of lead, cadmium, nickel, chromium, and mercury have been assessed in 28 body creams and lotions, 10 powders, 3 soaps, 5 eye make-ups, and 4 lipsticks widely available on Nigerian markets. The increases over suggested or mandated levels of lead in these creams and lotions ranged from 6.1 to 45.9 and from 1.2 to 9.2 mg kg⁻¹ when compared with Cosmetic Ingredients Review Expert Panel 2007 and German safe maximum permissible limit of lead in cosmetics, respectively. About 61% of the body cosmetics, the lotions, and the creams contained detectable levels of nickel ranging from 1.1 to 6.4-9.2 mg kg⁻¹. Chromium and mercury were undetected in 100% of the cosmetic product. Taken together, lead and cadmium were high in creams and lotions. Most of the imported creams and creamy white coloured cosmetics contained higher levels of metal contaminants than the other colours. Regulatory Agencies in developing nations should take appropriate action for cosmetics that contain lead and cadmium beyond the reference limits.

n-Dodecyl β-D-maltoside specifically competes with general anesthetics for anesthetic binding sites.

PubMed

Xu, Longhe; Matsunaga, Felipe; Xi, Jin; Li, Min; Ma, Jingyuan; Liu, Renyu

2014-01-01

We recently demonstrated that the anionic detergent sodium dodecyl sulfate (SDS) specifically interacts with the anesthetic binding site in horse spleen apoferritin, a soluble protein which models anesthetic binding sites in receptors. This raises the possibility of other detergents similarly interacting with and occluding such sites from anesthetics, thereby preventing the proper identification of novel anesthetic binding sites. n-Dodecyl β-D-maltoside (DDM) is a non-ionic detergent commonly used during protein-anesthetic studies because of its mild and non-denaturing properties. In this study, we demonstrate that SDS and DDM occupy anesthetic binding sites in the model proteins human serum albumin (HSA) and horse spleen apoferritin and thereby inhibit the binding of the general anesthetics propofol and isoflurane. DDM specifically interacts with HSA (Kd = 40 μM) with a lower affinity than SDS (Kd = 2 μM). DDM exerts all these effects while not perturbing the native structures of either model protein. Computational calculations corroborated the experimental results by demonstrating that the binding sites for DDM and both anesthetics on the model proteins overlapped. Collectively, our results indicate that DDM and SDS specifically interact with anesthetic binding sites and may thus prevent the identification of novel anesthetic sites. Special precaution should be taken when undertaking and interpreting results from protein-anesthetic investigations utilizing detergents like SDS and DDM.

Cepan Cream is used for the topical treatment of scars and keloids resulting from burns, post-operative scars, and contractures. Cepan Cream makes scars more elastic, softer and paler. Plant extracts, heparin and allantoin in Cepan act on the biochemical processes in the developing connective tissue, preventing the formation of hyperplastic scars. These active ingredients enhance swelling, softening and loosening of connective tissue. It exerts softening and smoothing action on indurated and hyperplastic scar tissue, improving collagen structure. It promotes tissue regeneration and reduces exuberant granulation. Cepan is well tolerated.

An anesthetic mixture of medetomidine (MED), midazolam (MID), and butorphanol (BUT) has been used in laboratory animals. We previously reported that this anesthetic mixture produced closely similar anesthetic effects in BALB/c and C57BL/6J strains. We also demonstrated the efficacy of atipamezole (ATI), an antagonist of MED that produced quick recovery from anesthesia in mice. Anesthetics have various anesthetic effects among animal strains. However, the differences in the effects of anesthetic mixtures in rats are unclear. In the present study, we first examined effects of the abovementioned anesthetic mixture using three different rat strains: Wistar (WST), Sprague-Dawley (SD), and Fischer 344 (F344). Second, we examined how different dosages and optimum injection timing of ATI affected recovery from anesthesia in rats. We used the anesthetic score to measure anesthetic duration and a pulse oximeter to monitor vital signs. We found no significant differences in anesthetic duration among the three different strains. However, recovery from anesthesia in the SD strain took significantly longer than in the other strains. The antagonistic effects of ATI (0.15 mg/kg and 0.75 mg/kg) were equivalent when administered at 30 min after anesthetic mixture administration. The antagonistic effects of ATI 0.75 mg/kg were stronger than those of ATI 0.15 mg/kg at 10 min after anesthetic mixture administration. This anesthetic mixture is a useful drug that can induce similar anesthetic effects in three different strains and has an antagonist, ATI, that makes rats quickly recover from anesthesia. These results may contribute to the welfare of laboratory animals.

Vulvovaginal candidiasis is known as one of the most common fungal infection among women of reproductive age and considered as an important public health problem. In recent years, due to resistance to common antifungal medication, the use of traditional medicine of anti-fungal and herbal treatment increased. Therefore the objective of this study was to determine the effects of vaginal cream, mixture of yogurt and honey and comparing it with clotrimazole vaginal cream on symptoms of Vulvovaginal candidiasis in patients. In this randomized, triple blind clinical trial of 70 non-pregnant women infected with Candidal vulvovaginitis were placed in two groups of Vaginal cream mixed of yogurt and honey recipients (N=35) and clotrimazole vaginal cream (N=35). Both groups were treated for 7 days. At the beginning of study, Clinical and laboratory signs and symptoms were registered 7 and 14 days after treatment by questionnaire, observation form and secretions culture results. Data by chi-square test, t test, McNemar tests were analyzed by SPSS version 21. Significance level of 0.05 was considered. The result of present study reveals the significant differences in symptom improvement of ' yogurt and honey, than clotrimazole group (P<0.05) and also Positive results of the first cultures (one week after treatment) in "yogurt and honey" and clotrimazole (20% versus 8.6%) and second time cultivation (14 days after treatment) (17/1% versus 8.6%) were similar and there was no significant differences between the two groups. (P>0.05) CONCLUSION: This study indicated that he therapeutic effects of vaginal cream, yogurt and honey is not only similar with clotrimazole vaginal cream but more effective in relieving some symptoms of vaginal candidiasis. Therefore, the use of this product can be suggested as an herbal remedy for candida infection treatment.

Premenopausal women with low calcium intakes consumed calcium-fortified ice cream daily for 28 days. Bone markers, NTX, CTX and PTH decreased significantly by 7 days, with some evidence of a calcium dose-dependent effect. Bone marker responses were observed within 1 h of consuming ice cream. Body weight remained constant over 28 days. Dietary calcium is important for lifelong bone health. Milk is a good source of bioavailable calcium, but consumption has declined among young adults. The aims were to determine whether calcium-fortified ice cream, a palatable source of calcium, produces significant, sustainable changes in bone turnover markers and parathyroid hormone (PTH) in premenopausal women with calcium intake below recommended UK levels. Eighty women, ages 20-39 years (calcium intake <750 mg/day) were randomised to consume lower saturated fat/sugar ice cream containing 96, 244, 459 or 676 mg calcium daily for 28 days. Urinary NTX/Cr, serum CTX, PINP, 1,25D and PTH were measured (baseline, days 1, 7 and 28). Acute changes in CTX and PTH were measured over 5 h (n = 29 women). There were significant mean decreases by 7 days in NTX/Cr, CTX, PTH and 1,25D and increases in PINP (one sample t tests), with a significant dose-dependent effect on CTX analysis of covariance. Only CTX remained suppressed at 28 days. Serum CTX and PTH decreased within 1 h. Body weight did not change significantly between baseline and 28 days. Daily consumption of calcium-fortified ice cream by premenopausal women may significantly reduce levels of the bone resorption marker serum CTX, without stimulating weight gain. The ice cream could be incorporated into the diet to replace low-calcium snacks and thus help individuals with habitually low calcium intakes to meet recommended intakes. The 244 mg calcium preparation would provide more than a quarter of the UK daily recommended nutrient intake for premenopausal women.

Structural, compositional, and sensorial properties of United States commercial ice cream products.

Commercial vanilla ice cream products from the United States (full fat, low fat, and nonfat) were analyzed for their structural, behavioral (i.e., melt rate and drip-through), compositional, and sensorial attributes. Mean size distributions of ice crystals and air cells, drip-through rates, percent partially coalesced fat, percent overrun and total fat, and density were determined. A trained panel carried out sensory analyses in order to determine correlations between ice cream microstructure attributes and sensory properties using a Spectrum(TM) descriptive analysis. Analyses included melt rate, breakdown, size of ice particulates (iciness), denseness, greasiness, and overall creaminess. To determine relationships and interactions, principle component analysis and multivariate pairwise correlation were performed within and between the instrumental and sensorial data. Greasiness and creaminess negatively correlated with drip-through rate and creaminess correlated with percent total fat and percent fat destabilization. Percent fat did not determine the melt rate on a sensorial level. However, drip-through rate at ambient temperatures was predicted by total fat content of the samples. Based on sensory analysis, high-fat products were noted to be creamier than low and nonfat products. Iciness did not correlate with mean ice crystal size and drip-through rate did not predict sensory melt rate. Furthermore, on a sensorial level, greasiness positively correlated with total percent fat destabilization and mean air cell size positively correlated with denseness. These results indicate that commercial ice cream products vary widely in composition, structure, behavior, and sensory properties. There is a wide range of commercial ice creams in the United States market, ranging from full fat to nonfat. In this research we showed that these ice creams vary greatly in their microstructures, behaviors (the melt/drip-though, collapse, and/or stand up properties of ice cream products at ambient temperatures), and sensory properties. © 2014 Institute of Food Technologists®

Efficacy of a Hand Regimen in Skin Barrier Protection in Individuals With Occupational Irritant Contact Dermatitis.

2016-11-01

Occupational irritant contact dermatitis (OICD) is a dif cult and hard to manage condition. It occurs more frequently in certain occupations where contact with harsh chemicals, use of alcohol-based disinfectants, and frequent hand washing heightens the risk. Treatment for OICD includes patient education in addition to physical, topical, and systemic therapies. To review the pathogenesis and treatment options for OICD and evaluate the ef cacy of a selective skin-care regimen involv- ing a hand protectant cream alone as well as combined with a repair cream and speci c cleanser. A single-center open study was performed comprising 42 healthy male and female adult volunteers prone to occupational irritant contact dermatitis due to frequent wet work or contact with detergents. Between day 0 and day 7, subjects applied a hand protectant cream as needed on both hands (at least twice daily). On days 7 to 14, subjects applied a hand protectant cream and cleanser as needed on both hands (at least twice daily) as well as a repair cream each evening. A diary log was given to each volunteer for application control and for a subjective evaluation of daily tolerability. In these subjects prone to occupational irritant contact dermatitis, the hand protectant cream applied during the initial 7-day period was effective in restoring the damaged skin barrier and improving the stratum corneum hydration. A regimen that combined the hand protectant and repair creams with a speci c cleanser during a further 7-day period allowed contin- ued improvement of skin hydration and additional clinical bene ts while respecting the skin barrier function. The results of this study support the use of a 3-step approach for patients who are at risk of repeated exposure to external irritants. J Drugs Dermatol. 2016;15(suppl 11):s81-85..
