A Comparison Study of the Blood Component Quality of Whole Blood Held Overnight at 4°C or Room Temperature  

PubMed Central

Background. The use of plasma frozen within 24?hrs is likely to increase. Whole blood (WB) and buffy coats (BCs) can be held for a few hrs or overnight before processing. Methods. Twenty-four bags of WB for plasma and 12 bags for platelet (PLT) concentrates were collected. The fresh frozen plasma (FFP) was prepared within 6?hrs. I-FP24 and II-FP24 samples were prepared either from leukodepleted WB that was held overnight or from WB that was held overnight before leukodepletion. The PLT concentrates (PCs) were prepared from BCs within 6?hrs (PC1) and within 18 to 24?hrs (PC2). The typical coagulation factors and some biochemical parameters were determined. Results. Compared to the FFP samples, the levels of FVII and FVIII in the I-FP24 and II-FP24 samples decreased significantly. The pH, Na+, LDH, and FHb levels differed significantly between II-FP24 and FFP. Compared to PC1, PC2 exhibited lower pH, pO2, and Na+ levels, a higher PLT count, and increased pCO2, K+, Lac, and CD62P expression levels. Conclusion. FP24 is best prepared from WB that was stored overnight at 4°C and then leukodepleted and separated within 24?hrs. PCs are best produced from BCs derived from WB that was held overnight at room temperature.

Feasibility of Overnight Closed-Loop Control Based on Hourly Blood Glucose Measurements  

PubMed Central

Introduction Safe and effective closed-loop control (artificial pancreas) is the ultimate goal of insulin delivery. In this study, we examined the performance of a closed-loop control algorithm used for the overnight time period to safely achieve a narrow target range of blood glucose (BG) concentrations prior to breakfast. The primary goal was to compare the quality of algorithm control during repeated overnight experiments. Materials and Methods Twenty-three subjects with type 1 diabetes performed 2 overnight experiments on each of three visits at the study site, resulting in 138 overnight experiments. On the first evening, the subject’s insulin therapy was applied; on the second, the insulin was delivered by an algorithm based on subcutaneous continuous glucose measurements (including meal control) until midnight. Overnight closed-loop control was applied between midnight and 6 a.m. based on hourly venous BG measurements during the first and second nights. Results The number of BG values within the target range (90–150 mg/dl) increased from 52.9% (219 out of 414 measure-ments) during the first nights to 72.2% (299 out of 414 measurements) during the second nights (p < .001, ?2-test). The occurrence of hypoglycemia interventions was reduced from 14 oral glucose interventions, the latest occurring at 2:36 a.m. during the first nights, to 1 intervention occurring at 1:02 a.m. during the second nights (p < .001, ?2-test). Conclusions Overnight controller performance improved when optimized initial control was given; this was suggested by the better metabolic control during the second night. Adequate controller run-in time seems to be important for achieving good overnight control. In addition, the findings demonstrate that hourly BG data are sufficient for the closed-loop control algorithm tested to achieve appropriate glycemic control.

Ambient overnight hold of whole blood prior to the manufacture of blood components.  

PubMed

Blood services routinely separate whole blood into components that are then stored under different conditions. The storage conditions used for whole blood prior to separation must therefore be a compromise between the needs of the red cells (which benefit from refrigeration) and plasma and platelets (which are better preserved at ambient temperature). For many years, the approach has been to manufacture plasma and platelet components on the day of blood collection, and to refrigerate any unprocessed blood for manufacture into red cell components on the following day. However, this can make it challenging to maintain adequate stocks of all components. The European practice of 'ambient hold' of whole blood for up to 24 hours prior to processing allows greater flexibility in blood component manufacture, and the data reviewed suggest there is relatively little impact on the quality of red cell or plasma components, and an improvement in the quality of platelet components.

Process improvement by eliminating mixing of whole blood units after an overnight hold prior to component production using the buffy coat method.  

PubMed

The elimination of a thorough manual mixing of whole blood (WB) which takes place following the overnight hold, but before the first centrifugation step, during buffy coat component production at Canadian Blood Services (CBS) was investigated. WB was pooled after donation and split. Pairs of platelet, red blood cell (RBC), and plasma components were produced, with half using the standard method and half using a method in which the mixing step was eliminated. Quality assessments included yield, pH, CD62P expression and morphology for platelets, hemoglobin, hematocrit, hemolysis, and supernatant K(+) for RBCs, and volume and factor VIII activity levels for plasma. All components, produced using either method, met CBS quality control criteria. There were no significant differences in platelet yield between components produced with and without mixing. A significant difference was seen for RBC hemolysis at expiry (P = 0.03), but for both groups, levels met quality control requirements. Noninferiority of components produced without mixing was confirmed for all parameters. Manual mixing is laborious and has a risk of repetitive strain for production staff and its significance is unclear. Elimination of this step will improve process efficiencies without compromising quality. PMID:24066260

The effects of repeated ingestion of high and low glucose-electrolyte solutions on gastric emptying and blood 2H2O concentration after an overnight fast.  

PubMed

The addition of carbohydrate to drinks designed to have a role in rehydrating the body is commonplace. The gastric emptying and fluid uptake characteristics following repeated ingestion of drinks with high and low glucose concentrations were examined in eight subjects (three male and five female). Following a 13 h fluid restriction period, the subjects ingested a volume of test solution amounting to 3 % of the initial body mass over a period of 60 min. Test drinks were 2 and 10 % glucose-electrolyte solutions with osmolalities of 189 (SD 3) and 654 (SD 3) mOsm/kg, respectively. The initial bolus of each test solution contained 10 g of (2)H(2)O. Blood samples were collected throughout drinking and for 60 min afterwards. Gastric volumes were determined via gastric aspiration at 15 min intervals for 120 min. No difference between trials in total stomach volume was observed until 30 min after the ingestion of the first bolus of test drink, but blood (2)H concentration was increased during both trials 10 min after ingestion of the first bolus. Blood (2)H concentration was greater at this time point during the 2 % glucose trial than during the 10 % glucose trial and remained higher for the duration of the trial with the exception of one time point. Urine volume at the end of the trial was greater in the 2 % glucose trial than in the 10 % glucose trial. It is concluded that the reduced overall rate of fluid uptake following ingestion of the 10 % glucose solution was due largely to a relatively slow rate of gastric emptying. PMID:21733327

Renal Arterial Blood Flow Measurement by Breath-held MRI: Accuracy in Phantom Scans and Reproducibility in Healthy Subjects  

PubMed Central

This study evaluates reliability of current technology for measurement of renal arterial blood flow by breath-held velocity-encoded MRI. Overall accuracy was determined by comparing MRI measurements with known flow in controlled flow loop phantom studies. Measurements using prospective and retrospective gating methods were compared in phantom studies with pulsatile flow, not revealing significant differences. Phantom study results showed good accuracy with deviations from true flow consistently below 13% for vessel diameters 3 mm and above. Reproducibility in human subjects was evaluated by repeat studies in six healthy control subjects, comparing immediate repetition of the scan, repetition of the scan plane scouting, and week-to-week variation in repeated studies. The standard deviation in the four-week protocol of repeated in-vivo measurements of single-kidney renal flow in normal subjects was 59.7 ml/min, corresponding with an average coefficient of variation of 10.55%. Comparison of RBF reproducibility with and without gadolinium contrast showed no significant differences in mean or standard deviation. A breakdown among error components showed corresponding marginal standard deviations (coefficients of variation) 23.8 ml/min (4.21%) for immediate repetition of the breath-held flow scan, 39.13 ml/min (6.90%) for repeated plane scouting, and 40.76 ml/min ( 7.20%) for weekly fluctuations in renal blood flow.

The overnight effect on the Taiwan stock market  

NASA Astrophysics Data System (ADS)

This study examines statistical regularities among three components of stocks and indices: daytime (trading hour) return, overnight (off-hour session) return, and total (close-to-close) return. Owing to the fact that the Taiwan Stock Exchange (TWSE) has the longest non-trading periods among major markets, the TWSE is selected to explore the correlation among the three components and compare it with major markets such as the New York Stock Exchange (NYSE) and the National Association of Securities Dealers Automated Quotation (NASDAQ). Analysis results indicate a negative cross correlation between the sign of daytime return and the sign of overnight return; possibly explaining why most stocks feature a negative cross correlation between daytime return and overnight return [F. Wang, S.-J. Shieh, S. Havlin, H.E. Stanley, Statistical analysis of the overnight and daytime return, Phys. Rev. E 79 (2009) 056109]. Additionally, the cross correlation between the magnitude of returns is analyzed. According to those results, a larger magnitude of overnight return implies a higher probability that the sign of the following daytime return is the opposite of the sign of overnight return. Namely, the predictability of daytime return might be improved when a stock undergoes a large magnitude of overnight return. Furthermore, the cross correlations of 29 indices of worldwide markets are discussed.

Ambulatory laparoscopic cholecystectomy: An audit of day case vs overnight surgery at a community hospital in Japan  

PubMed Central

AIM: To evaluate the applicability and safety of ambulatory laparoscopic cholecystectomy (LC) and to compare day case and overnight stay LC. METHODS: Data were collected retrospectively and consecutively for day case and overnight stay LC patients from July 1, 2009 to April 30, 2011. Outcomes were analyzed for patient demographics, operation time, blood loss during operation and frequency and reasons for unexpected or prolonged hospitalization in each group. RESULTS: There was no hospital mortality and no patient was readmitted with serious morbidity after discharge. 50 patients received a day case LC and 19 had an overnight stay LC. There was a significant difference in age between both groups (P < 0.02). There were no significant differences between the day case LC performed (n = 41) and failed (n = 9) groups and between the day case LC performed and the one night stay LC (n = 12) groups. There was a significant difference in age between the one night stay and more nights stay LC groups (P < 0.05). Thus, elderly patients showed a tendency to like to stay in hospital rather than being a day case. The proportion of unexpected or prolonged hospitalization was not significantly different between the day case and overnight stay LC groups, when the patient’s request was excluded. CONCLUSION: Day case LC can be performed with a low rate of complications. In overnight stay patients, there are many who could be performed safely as a day case. Moreover, we need to take special care to treat elderly patients.

Effects of acetazolamide on overnight oxygenation and acute mountain sickness in patients with asthma.  

PubMed

The aim of the study was to assess effects of acetazolamide in prevention of acute mountain sickness (AMS) and on overnight oxygenation, in patients with asthma treated at the altitude of 3,200 m. Sixteen patients with asthma, 6 males and 10 females, mean age 32 yrs, were first investigated at low altitude (760 m). They presented with mild airways obstruction, normal arterial blood gases, and normal oxygenation at night studied by pulse oximetry. After initial investigations, patients were divided by random number into the treated (T) and control (C) groups of eight patients each. T group patients received acetazolamide, 750 mg daily for 2 days, before the ascent and on the first day at altitude (3,200 m). Symptoms of AMS developed in seven patients from group C and in three from group T. The overnight pulse oximetry, performed on the first night at altitude, revealed that group T patients had statistically higher (p < 0.05) initial, 91 vs 87%, mean, 90 vs 86%, and minimum, 84 vs 75%, arterial oxygen saturation than group C patients. Overnight pulse oximetry was repeated on the 5th, 10th and 17th day at altitude, and showed that in group C patients, from the 5th day onwards, oxygenation improved to the level observed in group T patients on the first night. We conclude that pretreatment with acetazolamide before the ascent prevented patients with asthma from developing symptoms of AMS, and alleviated acute changes in arterial oxygen saturation brought about by the high altitude hypoxia.

Changes in overnight arterial oxygen saturation after mandibular setback.  

PubMed

Mandibular setback reduces space in the pharyngeal airway, and it has been suggested that it might induce sleep-disordered breathing. We report on its effects on space in the pharyngeal airway and respiratory function during sleep. We studied 78 patients (29 men and 49 women) in whom skeletal class III malocclusions had been corrected. The mean (range) age at operation was 24 (16-38) years and body mass index (BMI) 21.4 (16.1-30 .9)kg/m(2). Morphological changes were evaluated on lateral cephalograms taken three times: preoperatively, a few days postoperatively, and more than 6 months postoperatively. Overnight arterial oxygen saturation (SpO2) was measured by pulse oximetry 6 times: preoperatively, and on days 1, 3, 5, and 7, and 6 months postoperatively; oximetric indices were calculated. Those immediately after mandibular setback were significantly worse than those preoperatively, although they gradually improved. There were positive correlations between BMI and oximetric indices, and little association between changes in mandibular position and oximetric indices. There was no evidence of sleep-disordered breathing 6 months after mandibular setback because most patients adapt to the new environment for respiratory function during sleep. However, some (particularly obese) patients may develop sleep-disordered breathing just after mandibular setback. In such patients attention should be paid to respiratory function during sleep in the immediate postoperative period, and careful postoperative follow-up is needed. PMID:22853977

Effects of overnight refrigeration on the microscopic evaluation of sputum.  

PubMed Central

Microscopic evaluation of sputum permits selection of specimens suitable for culture, assessment of likely pathogens, and the best interpretation of culture results. We prospectively evaluated 50 sputum specimens which were promptly submitted to our clinical laboratory; smears and cultures were performed both immediately and after 20 h of refrigeration. Specimens were grouped according to the numbers of squamous epithelial cells and neutrophils per low-power field present on coded Gram-stained smears. The numbers of bacteria in five oil immersion fields were used to characterize smears for predominant, mixed, or scanty forms. After refrigeration, only three specimens changed group from a definite loss of squamous epithelial cells, and only two changed group from a definite loss of neutrophils. Based on cellular composition, the majority of samples would have been processed identically both before and after refrigeration. In contrast, organism forms detected on smears and their relative quantities were dramatically altered after refrigeration. A predominant smear form was gained in 11 and lost in 8 refrigerated specimens. The frequent changes on smears observed overall resulted from both increases and decreases in numbers of bacteria and yeasts. The majority of sputum culture results were insignificantly affected by the refrigeration of specimens. We conclude that 20 h of refrigeration renders sputum useless for the microscopic evaluation of potential pathogens and the subsequent interpretation of culture results. However, overnight refrigeration does not affect the determination from smears of sputum suitability for culture based on cellular composition.

Overnight Fasting Regulates Inhibitory Tone to Cholinergic Neurons of the Dorsomedial Nucleus of the Hypothalamus  

PubMed Central

The dorsomedial nucleus of the hypothalamus (DMH) contributes to the regulation of overall energy homeostasis by modulating energy intake as well as energy expenditure. Despite the importance of the DMH in the control of energy balance, DMH-specific genetic markers or neuronal subtypes are poorly defined. Here we demonstrate the presence of cholinergic neurons in the DMH using genetically modified mice that express enhanced green florescent protein (eGFP) selectively in choline acetyltransferase (Chat)-neurons. Overnight food deprivation increases the activity of DMH cholinergic neurons, as shown by induction of fos protein and a significant shift in the baseline resting membrane potential. DMH cholinergic neurons receive both glutamatergic and GABAergic synaptic input, but the activation of these neurons by an overnight fast is due entirely to decreased inhibitory tone. The decreased inhibition is associated with decreased frequency and amplitude of GABAergic synaptic currents in the cholinergic DMH neurons, while glutamatergic synaptic transmission is not altered. As neither the frequency nor amplitude of miniature GABAergic or glutamatergic postsynaptic currents is affected by overnight food deprivation, the fasting-induced decrease in inhibitory tone to cholinergic neurons is dependent on superthreshold activity of GABAergic inputs. This study reveals that cholinergic neurons in the DMH readily sense the availability of nutrients and respond to overnight fasting via decreased GABAergic inhibitory tone. As such, altered synaptic as well as neuronal activity of DMH cholinergic neurons may play a critical role in the regulation of overall energy homeostasis.

Alpha activity during rem sleep contributes to overnight improvement in performance on a visual discrimination task.  

PubMed

The purpose of this preliminary study was to clarify the association between cortical and subcortical activities during REM and non-REM sleep with overnight improvement of performance on a procedural memory task. Eleven healthy volunteers (M age = 23.8 yr., SD = 3.1) participated in this study which was conducted over two consecutive nights: an adaptation night and the experimental night. They underwent a visual discrimination task before and after the experimental night. A positive correlation was observed between overnight performance improvement on the visual discrimination task and EEG alpha band power during REM sleep, while no significant correlation was observed between the performance and either the amount of Stage REM sleep, REM activity, or other sleep variables. The findings corroborate other studies and suggest that cortical activity during REM sleep contributed to procedural memory consolidation and highlights the importance of measuring quantitative REM sleep components to elucidate the role of physiological sleep on memory consolidation in humans.

Molecular characterization of Acanthamoeba isolated from amebic keratitis related to orthokeratology lens overnight wear  

PubMed Central

In an effort to characterize, on the molecular scale, the Acanthamoeba initially isolated from the cornea of an amoebic keratitis patient associated with overnight-wear orthokeratology lens in Korea, we conducted mitochondrial DNA restriction fragment length polymorphism, 18S rDNA sequencing, and drug sensitivity analyses on the isolate (KA/PE1). The patient was treated with polyhexamethylene biguanide, chlorhexidine and oral itraconazole, which resulted in resolution of the patient's ocular inflammation. The majority of the molecular characteristics of the KA/PE1 were determined to be identical, or quite similar, to those of A. castellanii Ma strain, which had been isolated also from amoebic keratitis. The risk of Acanthamoeba keratitis as a potential complication of overnight orthokeratology is briefly discussed.

Reduced overnight consolidation of procedural learning in chronic medicated schizophrenia is related to specific sleep stages.  

PubMed

We previously reported that patients with schizophrenia failed to demonstrate normal sleep-dependent improvement in motor procedural learning. Here, we tested whether this failure was associated with the duration of Stage 2 sleep in the last quartile of the night (S2q4) and with spindle activity during this epoch. Fourteen patients with schizophrenia and 15 demographically matched controls performed a motor sequence task (MST) before and after a night of polysomnographically monitored sleep. Patients showed no significant overnight task improvement and significantly less than controls, who did show significant improvement. While there were no group differences in overall sleep architecture, patients showed significant reductions in fast sigma frequency power (45%) and in spindle density (43%) during S2q4 sleep at the electrode proximal to the motor cortex controlling the hand that performed the MST. Although spindle activity did not correlate with overnight improvement in either group, S2q4 sleep duration in patients significantly correlated with the plateau level of overnight improvement seen at the end of the morning testing session, and slow wave sleep (SWS) duration correlated with the delay in reaching this plateau. SWS and S2q4 sleep each predicted the initial level of overnight improvement in schizophrenia, and their product explained 77% of the variance, suggesting that both sleep stages are necessary for consolidation. These findings replicate our prior observation of reduced sleep-dependent consolidation of motor procedural learning in schizophrenia and link this deficit to specific sleep stages. They provide further evidence that sleep is an important contributor to cognitive deficits in schizophrenia. PMID:19665729

Here, we tested whether this failure was associated with the duration of Stage 2 sleep in the last quartile of the night (S2q4) and with spindle activity during this epoch. Fourteen patients with schizophrenia and 15 demographically matched controls performed a motor sequence task (MST) before and after a night of polysomnographically monitored sleep. Patients showed no significant overnight task improvement and significantly less than controls, who did show significant improvement. While there were no group differences in overall sleep architecture, patients showed significant reductions in fast sigma frequency power (45%) and in spindle density (43%) during S2q4 sleep at the electrode proximal to the motor cortex controlling the hand that performed the MST. Although spindle activity did not correlate with overnight improvement in either group, S2q4 sleep duration in patients significantly correlated with the plateau level of overnight improvement seen at the end of the morning testing session, and slow wave sleep (SWS) duration correlated with the delay in reaching this plateau. SWS and S2q4 sleep each predicted the initial level of overnight improvement in schizophrenia, and their product explained 77% of the variance, suggesting that both sleep stages are necessary for consolidation. These findings replicate our prior observation of reduced sleep-dependent consolidation of motor procedural learning in schizophrenia and link this deficit to specific sleep stages. They provide further evidence that sleep is an important contributor to cognitive deficits in schizophrenia.

Intragastric protein administration stimulates overnight muscle protein synthesis in elderly men.  

PubMed

The loss of skeletal muscle mass with aging has been attributed to an impaired muscle protein synthetic response to food intake. Therefore, nutritional strategies are targeted to modulate postprandial muscle protein accretion in the elderly. The purpose of this study was to assess the impact of protein administration during sleep on in vivo protein digestion and absorption kinetics and subsequent muscle protein synthesis rates in elderly men. Sixteen healthy elderly men were randomly assigned to an experiment during which they were administered a single bolus of intrinsically l-[1-(13)C]phenylalanine-labeled casein protein (PRO) or a placebo (PLA) during sleep. Continuous infusions with l-[ring-(2)H(5)]phenylalanine and l-[ring-(2)H(2)]tyrosine were applied to assess in vivo dietary protein digestion and absorption kinetics and subsequent muscle protein synthesis rates during sleep. We found that exogenous phenylalanine appearance rates increased following protein administration. The latter stimulated protein synthesis, resulting in a more positive overnight whole body protein balance (0.30 ± 0.1 vs. 11.8 ± 1.0 ?mol phenylalanine·kg(-1)·h(-1) in PLA and PRO, respectively; P < 0.05). In agreement, overnight muscle protein fractional synthesis rates were much greater in the PRO experiment (0.045 ± 0.002 vs. 0.029 ± 0.002%/h, respectively; P < 0.05) and showed abundant incorporation of the amino acids ingested via the intrinsically labeled protein (0.058 ± 0.006%/h). This is the first study to show that dietary protein administration during sleep is followed by normal digestion and absorption kinetics, thereby stimulating overnight muscle protein synthesis. Dietary protein administration during sleep stimulates muscle protein synthesis and improves overnight whole body protein balance. These findings may provide a basis for novel interventional strategies to attenuate muscle mass loss. PMID:21917635

Overnight malodor effect with a 0.454% stabilized stannous fluoride sodium hexametaphosphate dentifrice.  

PubMed

Stannous fluoride (SnF2) is a broad-spectrum antimicrobial agent effective against caries, plaque, and gingivitis. Because oral malodor has a microbial etiology, the potential immediate effects of SnF2 on malodor were evaluated in 2 independent, randomized clinical trials. Both studies used a similar double-blind, crossover design, with subjects randomized to a treatment sequence with a 0.454% stabilized SnF2 sodium hexametaphosphate dentifrice or sodium fluoride dentifrice control. Overnight malodor was assessed at baseline in the morning before brushing and 24 hours later, after morning and evening brushing with the assigned product. In the first study, volatile sulfur compounds (VSC) were measured instrumentally via a portable sulfide monitor (Halimeter) with an electrochemical gas sensor. The second study used second-person malodor assessment on a 9-point hedonic scale. Treatments were compared at each time point using analysis of variance for crossover designs. Seventy-five subjects completed the evaluation (26 in the first and 49 in the second clinical trial). The use of the stabilized SnF2 dentifrice resulted in statistically significant reduction of overnight VSC (P <.03) and the overnight hedonic scores (P <.02) relative to the negative control after 1 day of product use. These 2 randomized, controlled clinical trials provide evidence of significant immediate malodor activity for a 0.454% stabilized SnF2 sodium hexametaphosphate dentifrice. PMID:18186171

Practical closed-loop insulin delivery. A system for the maintenance of overnight euglycemia and the calculation of basal insulin requirements in insulin-dependent diabetics.  

PubMed

We evaluated a practical closed-loop system of insulin delivery consisting of hourly blood glucose determinations using glucose oxidase reagent strips and an intravenous infusion of insulin controlled by a commonly available controller. In 25 insulin-dependent diabetic subjects, this system was successful in achieving and maintaining near euglycemia (blood glucose, 101 +/- 2 mg/dL, mean +/- SE) in the fasting state between 0200 and 0800 hours. This system may be useful in the management of insulin-dependent diabetic patients in various hospital settings. Also, in 10 subjects treated subsequently using a continuous subcutaneous insulin infusion, the mean hourly insulin infusion rate using the described system correlated well (r = 0.92) with the optimal overnight basal rate needed during continous subcutaneous insulin infusion therapy.

Outcomes of Operations Performed by Attending Surgeons after Overnight Trauma Shifts  

PubMed Central

BACKGROUND To date, work-hour restrictions have not been imposed on attending surgeons in the United States. The purpose of this study was to investigate the impact of working an overnight trauma shift on outcomes of general surgery operations performed the next day by the post-call attending physician. STUDY DESIGN Consecutive patients over a 3.5-year period undergoing elective general surgical procedures were reviewed. Procedures were limited to hernia repairs (inguinal and ventral), cholecystectomies, and intestinal operations. Any operations that were performed the day after the attending surgeon had taken an overnight trauma shift were considered post-call (PC) cases; all other cases were considered nonpost-call (NP). Outcomes from the PC operations were compared with those from the NP operations. RESULTS There were 869 patients identified; 132 operations were performed PC and 737 were NP. The majority of operations included hernia repairs (46%), followed by cholecystectomies (35%), and intestinal procedures (19%). Overall, the PC operations did not differ from the NP operations with respect to complication rate (13.7% vs 13.5%, p = 0.93) or readmission within 30 days (5% vs 6%, p = 0.84). Additionally, multivariable logistic regression failed to identify an association between PC operations and the development of adverse outcomes. Follow-up was obtained for an average of 3 months. CONCLUSIONS Performance of general surgery operations the day after an overnight in-hospital trauma shift did not affect complication rates or readmission rates. At this time, there is no compelling evidence to mandate work-hour restrictions for attending general surgeons.

Transcranial direct current stimulation reduces negative affect but not cigarette craving in overnight abstinent smokers.  

PubMed

Transcranial direct current stimulation (tDCS) can enhance cognitive control functions including attention and top-down regulation over negative affect and substance craving in both healthy and clinical populations, including early abstinent (?1.5?h) smokers. The aim of this study was to assess whether tDCS modulates negative affect, cigarette craving, and attention of overnight abstinent tobacco dependent smokers. In this study, 24 smokers received a real and a sham session of tDCS after overnight abstinence from smoking on two different days. We applied anode to the left dorsolateral prefrontal cortex and cathode to the right supra-orbital area for 20?min with a current of 2.0?mA. We used self-report questionnaires Profile of Mood States (POMS) to assess negative affect and Urge to Smoke (UTS) Scale to assess craving for cigarette smoking, and a computerized visual target identification task to assess attention immediately before and after each tDCS. Smokers reported significantly greater reductions in POMS scores of total mood disturbance and scores of tension-anxiety, depression-dejection, and confusion-bewilderment subscales after real relative to sham tDCS. Furthermore, this reduction in negative affect positively correlated with the level of nicotine dependence as assessed by Fagerström scale. However, reductions in cigarette craving after real vs. sham tDCS did not differ, nor were there differences in reaction time or hit rate change on the visual task. Smokers did not report significant side effects of tDCS. This study demonstrates the safety of tDCS and its promising effect in ameliorating negative affect in overnight abstinent smokers. Its efficacy in treating tobacco dependence deserves further investigation. PMID:24065930

Overnight switch from ropinirole to transdermal rotigotine patch in patients with Parkinson disease  

PubMed Central

Background A recent trial involving predominantly Caucasian subjects with Parkinson Disease (PD) showed switching overnight from an oral dopaminergic agonist to the rotigotine patch was well tolerated without loss of efficacy. However, no such data have been generated for Korean patients. Methods This open-label multicenter trial investigated PD patients whose symptoms were not satisfactorily controlled by ropinirole, at a total daily dose of 3 mg to 12 mg, taken as monotherapy or as an adjunct to levodopa. Switching treatment from oral ropinirole to transdermal rotigotine was carried out overnight, with a dosage ratio of 1.5:1. After a 28-day treatment period, the safety and tolerability of switching was evaluated. Due to the exploratory nature of this trial, the effects of rotigotine on motor and nonmotor symptoms of PD were analyzed in a descriptive manner. Results Of the 116 subjects who received at least one treatment, 99 (85%) completed the 28-day trial period. Dose adjustments were required for 11 subjects who completed the treatment period. A total of 76 treatment-emergent adverse events (AEs) occurred in 45 subjects. No subject experienced a serious AE. Thirteen subjects discontinued rotigotine prematurely due to AEs. Efficacy results suggested improvements in both motor and nonmotor symptoms and quality of life after switching. Fifty-two subjects (46%) agreed that they preferred using the patch over oral medications, while 31 (28%) disagreed. Conclusions Switching treatment overnight from oral ropinirole to transdermal rotigotine patch, using a dosage ratio of 1.5:1, was well tolerated in Korean patients with no loss of efficacy. Trial registration This trial is registered with the ClincalTrails.gov Registry (NCT00593606).

Prolonged respiratory illness after single overnight continuous positive airway pressure humidification: endotoxin as the suspect.  

PubMed

A patient developed a prolonged respiratory illness after a single overnight use of tap water to humidify air supplied by a constant positive airway pressure (CPAP) device, which she had previously used for six years without difficulty. During those years, she used only distilled water for this purpose, as instructed by her sleep specialist. Analysis of the well water supplying her home showed no microorganisms, metals or other analytes likely to have caused her illness, but endotoxin was found at concentrations well above that recommended by the U.S. Pharmacopeia, as a maximum in water which may be inhaled as an aerosol.

Association between posttest dexamethasone and cortisol concentrations in the 1 mg overnight dexamethasone suppression test  

PubMed Central

It has been suggested that comparison of posttest dexamethasone and cortisol concentrations may improve the evaluation of the dexamethasone suppression test (DST) for Cushing's syndrome. In particular, this would be reasonable if posttest cortisol differs by dexamethasone levels within the range that is usually attained in the DST. Using fractional polynomial regression, we therefore studied the association between posttest 0800?h dexamethasone and cortisol levels in 53 subjects without Cushing's syndrome who were tested with the 1?mg overnight DST. Plasma dexamethasone was associated with plasma cortisol (P<0.001), and the regression line suggested a strong negative association related to dexamethasone levels <5?nmol/l. However, among the 94% of subjects with plasma dexamethasone >5.0?nmol/l, there was no association between dexamethasone and cortisol levels (P=0.55). In conclusion, subjects tested with the 1?mg overnight DST usually attain an 0800?h plasma dexamethasone >5?nmol/l, and plasma cortisol does not differ by plasma dexamethasone in these subjects. This suggests that routine comparison of dexamethasone and cortisol levels may not be a useful approach to improve the performance of the 1?mg DST. However, dexamethasone measurements may identify subjects with inadequately low plasma dexamethasone and may therefore be of value when retesting subjects with possibly false-positive DST results.

Behavioral Approaches to Training Developmentally Disabled Children for an Overnight EEG Procedure  

PubMed Central

Smith-Lemli-Opitz syndrome (SLOS) is a genetic syndrome associated with multiple congenital malformations, mental retardation, and autism spectrum behaviors. This clinical protocol was part of a larger study investigating the effects of a cholesterol-lowering medication for SLOS patients. Behavioral therapists were consulted to facilitate participants’ cooperation with an overnight electroencephalogram (EEG). Seventeen children participated in one 1-hour training session of a mock EEG. Behavioral methods included task analysis, differential reinforcement, and escape extinction. Descriptive data reveal low cognitive and adaptive functioning. Fifty three percent of children tolerated all steps of the training procedure and 88% of participants tolerated all of the actual EEG procedure. Behavioral methods of training children may be an effective preparation for EEG procedures for children with SLOS. This study indicates that sedation, anesthesia, or restraints are not necessary to accomplish EEG testing of children with SLOS. Results may generalize to children with a range of disabilities.

Predictors of Overnight Hospital Admission in Older African American and Caucasian Medicare Beneficiaries  

PubMed Central

Background. Potential disparities in health care utilization were examined using overnight hospitalization data from the University of Alabama at Birmingham Study of Aging, a longitudinal investigation of a stratified sample of Medicare beneficiaries. Methods. Racial differences in self-reported surgical and nonsurgical overnight hospital admissions were examined using Cox proportional hazards models. Andersen’s Behavioral Model provided the conceptual framework to identify other potential predictors of admission. Results. Nine hundred and forty-two participants, 50.1% African American, provided data at baseline and at least one follow-up assessment (mean age = 75.3 years, range: 65–106). African Americans were less likely to utilize surgical admissions compared with Caucasians in a bivariate model (hazard ratio = 0.63, 95% confidence interval = 0.41–0.98). This effect was not significant after controlling for demographics and self-reported physical health. Additional bivariate predictors of surgical admission were intact mental status, having private insurance, and higher education. African Americans were less likely to utilize nonsurgical admissions in both bivariate (hazard ratio = 0.74, 95% confidence interval = 0.59–0.93) and covariate-adjusted models (hazard ratio = 0.64, 95% confidence interval = 0.50–0.84). This effect was significantly stronger for men than for women, with African American men only 0.50 times as likely as Caucasian men to report a nonsurgical admission. Other bivariate predictors of nonsurgical admission were increased age, poor physical health, negative psychological characteristics, higher levels of social support, and low perceived discrimination. Conclusion. Underutilization of services has been linked to increased mortality in African Americans. Modifications in mutable domains associated with service utilization such as perceived discrimination, social support, and having private insurance may be beneficial.

Overnight atmospheric transport and chemical processing of photochemically aged Houston urban and petrochemical industrial plume  

NASA Astrophysics Data System (ADS)

Overnight atmospheric transport and chemical evolution of photochemically aged Houston urban and petrochemical industrial plume were investigated in July 2005. We report here on the 26 July episode in which the aged plume was tagged 1.5 h before sunset with a pair of free-floating controlled meteorological balloons, which guided quasi-Lagrangian aircraft sampling in the plume as it was advected 300 km to the north over 8 h. The aged plume around sunset was well mixed within a 1600 m residual layer, and was characterized by enhanced levels of aerosol, O3, CO, olefins, acetaldehyde, total odd nitrogen compounds (NOy), and relatively small amounts (<1 ppbv) of NOx. The plume experienced appreciable shearing overnight due to the development of a low-altitude nocturnal jet between 300 and 500 m above mean sea level (MSL). However, the plume above 600 m MSL remained largely undiluted even after 8 h of transport due to lack of turbulent mixing above the jet. About 40-60% of the NOx present in the aged plume around sunset was found to be depleted over this 8 h period. A constrained plume modeling analysis of the quasi-Lagrangian aircraft observations suggested that by dawn this NOx was converted to nitric acid, organic nitrates, and peroxy acyl nitrates via reactions of NO3 radicals with enhanced levels of olefins and aldehydes in the plume. Sensitivity of NOx depletion to heterogeneous hydrolysis of N2O5 on aerosols was examined. These results have significant implications for the impacts of urban and industrial pollution on far downwind regions.

Overnight Resting of PBMC Changes Functional Signatures of Antigen Specific T- Cell Responses: Impact for Immune Monitoring within Clinical Trials.  

PubMed

Polyfunctional CD4 or CD8 T cells are proposed to represent a correlate of immune control for persistent viruses as well as for vaccine mediated protection against infection. A well-suited methodology to study complex functional phenotypes of antiviral T cells is the combined staining of intracellular cytokines and phenotypic marker expression using polychromatic flow cytometry. In this study we analyzed the effect of an overnight resting period at 37°C on the quantity and functionality of HIV-1, EBV, CMV, HBV and HCV specific CD4 and CD8 T-cell responses in a cohort of 21 individuals. We quantified total antigen specific T cells by multimer staining and used 10-color intracellular cytokine staining (ICS) to determine IFN?, TNF?, IL2 and MIP1? production. After an overnight resting significantly higher numbers of functionally active T cells were detectable by ICS for all tested antigen specificities, whereas the total number of antigen specific T cells determined by multimer staining remained unchanged. Overnight resting shifted the quality of T-cell responses towards polyfunctionality and increased antigen sensitivity of T cells. Our data suggest that the observed effect is mediated by T cells rather than by antigen presenting cells. We conclude that overnight resting of PBMC prior to ex vivo analysis of antiviral T-cell responses represents an efficient method to increase sensitivity of ICS-based methods and has a prominent impact on the functional phenotype of T cells.

Hot rocks or no hot rocks: overnight retreat availability and selection by a diurnal lizard.  

PubMed

I used radio telemetry to determine the effects of substrate size and composition on overnight retreat site selection by western fence lizards (Sceloporus occidentalis). In watersheds of northern California (USA), these lizards occupy two habitat types differing in substrate characteristics: rocky cobble bars found in the dry, active channels of rivers and grassy upland meadows. Rocky substrates, found almost exclusively on cobble bars, provided warmer potential retreat sites than all available retreat sites on meadows during the first 5 h of inactivity. Only cobble and sand substrates provided retreats with temperatures within the preferred daily active range (32-36 degrees C) during the inactive period for these lizards (1900-0900 hours). Females on a cobble bar used rocks as retreats on >90% of nights during the breeding season whereas females on a meadow used wood (>70% of nights) and burrows (>25% of nights). In contrast to females, cobble bar males used rocks significantly less frequently (<70%) and slept in the open air significantly more frequently (25% vs. <1%). Cobble bar females further, showed a significant preference for cobbles 15 cm thick, whereas the rocks used by males did not differ significantly in thickness from those measured in randomly placed transects. Rocks 15 cm thick were the warmest retreats commonly available on this habitat type. Thus, thermal microenvironments available to and chosen by gravid female lizards differ considerably between river and non-river habitats. PMID:12802672

Pattern Recognition of Overnight Intracranial Pressure Slow Waves using Morphological Features of Intracranial Pressure Pulse  

PubMed Central

This study aimed to develop a new approach to detect intracranial pressure (ICP) slow waves based on morphological changes of ICP pulse waveforms. A recently proposed Morphological Clustering and Analysis of ICP Pulse (MOCAIP) algorithm was utilized to calculate a set of metrics that characterize ICP pulse morphology. A regularized linear quadratic classifier was used to test the hypothesis that classification between ICP slow wave and flat ICP could be achieved using features composed of mean values and dispersion of 24 MOCAIP metrics. To optimize the classification performance, three feature selection techniques (differential evolution, discriminant analysis and analysis of variance) were applied to find an optimal set of MOCAIP metrics under different criteria. In addition, we selected three sets of metrics common to those found by combination of two selection methods, to be used as classification features (differential evolution and analysis of variance, discriminant analysis and analysis of variance, and combination of differential evolution and discriminant analysis). To test the approach, a total of 276 selections of ICP recordings corresponding to two patterns without waves and containing slow waves were obtained from overnight ICP studies of 44 hydrocephalus patients performed at the UCLA Adult Hydrocephalus Center. Our results showed that the best classification performance of differentiation of slow waves from the ICP recording without slow waves was obtained using the combination of metrics common to both differential evolution and analysis of variance methods; achieving an accuracy of 89%, specificity 96%, and sensitivity 83%.

Quantitative Phenotyping of Duchenne Muscular Dystrophy Dogs by Comprehensive Gait Analysis and Overnight Activity Monitoring  

PubMed Central

The dystrophin-deficient dog is excellent large animal model for testing novel therapeutic modalities for Duchenne muscular dystrophy (DMD). Despite well-documented descriptions of dystrophic symptoms in these dogs, very few quantitative studies have been performed. Here, we developed a comprehensive set of non-invasive assays to quantify dog gait (stride length and speed), joint angle and limb mobility (for both forelimb and hind limb), and spontaneous activity at night. To validate these assays, we examined three 8-m-old mix-breed dystrophic dogs. We also included three age-matched siblings as the normal control. High-resolution video recorders were used to digitize dog walking and spontaneous movement at night. Stride speed and length were significantly decreased in affected dogs. The mobility of the limb segments (forearm, front foot, lower thigh, rear foot) and the carpus and hock joints was significantly reduced in dystrophic dogs. There was also a significant reduction of the movement in affected dogs during overnight monitoring. In summary, we have established a comprehensive set of outcome measures for clinical phenotyping of DMD dogs. These non-invasive end points would be valuable in monitoring disease progression and therapeutic efficacy in translational studies in the DMD dog model.

The Effect of Overnight In-House Attending Coverage on Perceptions of Care and Education on a General Medical Service  

PubMed Central

Background An increased emphasis on patient safety has led to calls for closer supervision of medical trainees. It is unclear what effect an increased degree of faculty presence will have on educational and clinical outcomes. The aim of this study was to evaluate resident and attending attitudes and preferences regarding overnight attending supervision. Methods This study was a cross-sectional electronic survey of physicians. Participants were resident and faculty physicians recently on inpatient service rotations after implementation of an overnight attending coverage system. Results Of 58 total respondents, most faculty (91%) and resident (92%) physicians reported they were satisfied with the overall quality of care delivered and believed the quality of care delivered overnight improved with an in-house attending system (90% and 85%, respectively). Most resident physicians (82%) believed the educational experience improved with the system of increased attending availability. Nearly all faculty (95%) and resident (97%) physicians preferred the in-house attending system to the traditional system of attendings being available by pager. The implementation of such coverage resulted in increased cost to the hospital for compensating covering hospitalist physicians. Conclusion In-house attending coverage was acceptable to both residents and faculty, with perceived improvements in quality and educational experience.

Overnight closed loop insulin delivery (artificial pancreas) in adults with type 1 diabetes: crossover randomised controlled studies  

PubMed Central

Objective To compare the safety and efficacy of overnight closed loop delivery of insulin (artificial pancreas) with conventional insulin pump therapy in adults with type 1 diabetes. Design Two sequential, open label, randomised controlled crossover, single centre studies. Setting Clinical research facility. Participants 24 adults (10 men, 14 women) with type 1 diabetes, aged 18-65, who had used insulin pump therapy for at least three months: 12 were tested after consuming a medium sized meal and the other 12 after consuming a larger meal accompanied by alcohol. Intervention During overnight closed loop delivery, sensor measurements of glucose were fed into a computer algorithm, which advised on insulin pump infusion rates at 15 minute intervals. During control nights, conventional insulin pump settings were applied. One study compared closed loop delivery of insulin with conventional pump therapy after a medium sized evening meal (60 g of carbohydrates) at 1900, depicting the scenario of “eating in.” The other study was carried out after a later large evening meal (100 g of carbohydrates) at 2030, accompanied by white wine (0.75 g/kg ethanol) and depicted the scenario of “eating out.” Main outcome measures The primary outcome was the time plasma glucose levels were in target (3.91-8.0 mmol/L) during closed loop delivery and a comparable control period. Secondary outcomes included pooled data analysis and time plasma glucose levels were below target (?3.9 mmol/L). Results For the eating in scenario, overnight closed loop delivery of insulin increased the time plasma glucose levels were in target by a median 15% (interquartile range 3-35%), P=0.002. For the eating out scenario, closed loop delivery increased the time plasma glucose levels were in target by a median 28% (2-39%), P=0.01. Analysis of pooled data showed that the overall time plasma glucose was in target increased by a median 22% (3-37%) with closed loop delivery (P<0.001). Closed loop delivery reduced overnight time spent hypoglycaemic (plasma glucose ?3.9 mmol/L) by a median 3% (0-20%), P=0.04, and eliminated plasma glucose concentrations below 3.0 mmol/L after midnight. Conclusion These two small crossover trials suggest that closed loop delivery of insulin may improve overnight control of glucose levels and reduce the risk of nocturnal hypoglycaemia in adults with type 1 diabetes.

Coal leases held real property  

SciTech Connect

Coal leases, which granted an exclusive, 20-year right to mine and dispose of coal, and provided for 20-year renewal options, held community real property so that any lease conveyance was void unless joined in by both spouses. In Padilla vs Roller (94 NM 234, 608 P.2d 1116 (1980), the court confronted the question of whether the transfers of a coal lease were void for the failure of the conveyor's wife to sign the transfer document. In a terse opinion written by Justice Federici, the New Mexico Supreme Court analogized the Padilla case to earlier cases involving other mineral leases. The court pointed out that oil, gas, and mineral leases had been held to be real property. The case of Terry vs Humphreys (1922) established that an oil or gas lease extending over a period of more than five years represents real property of the community and, consequently, requires the joinder of both spouses for its valid conveyance. The Padilla decision, in light of relevant case law, represents a consistent extension of the Humphreys rule. The terms of the leases involved in Padilla were similar to the terms of the leases construed in earlier cases. The fact that coal, rather than oil or gas, was at issue afforded no reason for barring the appliation of the rule. The Padilla decision, then, is a reasonable extension of well-established law into an increasingly significant area of resource development.

Effect of a Protected Sleep Period on Hours Slept During Extended Overnight In-hospital Duty Hours Among Medical Interns  

PubMed Central

Context A 2009 Institute of Medicine report recommended protected sleep periods for medicine trainees on extended overnight shifts, a position reinforced by new Accreditation Council for Graduate Medical Education requirements. Objective To evaluate the feasibility and consequences of protected sleep periods during extended duty. Design, Setting, and Participants Randomized controlled trial conducted at the Philadelphia VA Medical Center medical service and Oncology Unit of the Hospital of the University of Pennsylvania (2009–2010). Of the 106 interns and senior medical students who consented, 3 were not scheduled on any study rotations. Among the others, 44 worked at the VA center, 16 at the university hospital, and 43 at both. Intervention Twelve 4-week blocks were randomly assigned to either a standard intern schedule (extended duty overnight shifts of up to 30 hours; equivalent to 1200 overnight intern shifts at each site), or a protected sleep period (protected time from 12:30 AM to 5:30 AM with handover of work cell phone; equivalent to 1200 overnight intern shifts at each site). Participants were asked to wear wrist actigraphs and complete sleep diaries. Main Outcome Measures Primary outcome was hours slept during the protected period on extended duty overnight shifts. Secondary outcome measures included hours slept during a 24-hour period (noon to noon) by day of call cycle and Karolinska sleepiness scale. Results For 98.3% of on-call nights, cell phones were signed out as designed. At the VA center, participants with protected sleep had a mean 2.86 hours (95% CI, 2.57–3.10 hours) of sleep vs 1.98 hours (95% CI, 1.68–2.28 hours) among those who did not have protected hours of sleep (P < .001). At the university hospital, participants with protected sleep had a mean 3.04 hours (95% CI, 2.77–3.45 hours) of sleep vs 2.04 hours (95% CI, 1.79–2.24) among those who did not have protected sleep (P <.001). Participants with protected sleep were significantly less likely to have call nights with no sleep: 5.8% (95% CI, 3.0%–8.5%) vs 18.6% (95% CI, 13.9%–23.2%) at the VA center (P <.001) and 5.9% (95% CI, 3.1%–8.7%) vs 14.2% (95% CI, 9.9%–18.4%) at the university hospital (P=.001). Participants felt less sleepy after on-call nights in the intervention group, with Karolinska sleepiness scale scores of 6.65 (95% CI, 6.35–6.97) vs 7.10 (95% CI, 6.85–7.33; P=.01) at the VA center and 5.91 (95% CI, 5.64–6.16) vs 6.79 (95% CI, 6.57–7.04; P <.001) at the university hospital. Conclusions For internal medicine services at 2 hospitals, implementation of a protected sleep period while on call resulted in an increase in overnight sleep duration and improved alertness the next morning.

Overnight versus progressive conversion of multiple daily-dose divalproex to once-daily divalproex extended release: which strategy is better tolerated by adults with intellectual disabilities?  

PubMed

Divalproex (DVP) delayed release and DVP extended release (DVP ER) are approved by the Food and Drug Administration for bipolar disorder, epilepsy, and migraine prophylaxis. Divalproex ER is given once daily, improving compliance and reducing adverse events. Overnight switch to DVP ER is advised in the package insert but could produce more adverse events in this susceptible population. In this pilot study, we compared tolerability of overnight versus gradual switching to DVP ER in 16 adults with intellectual and developmental disabilities receiving DVP, in 9 for epilepsy and in all 16 for comorbid bipolar disorder. The study design was open with parallel groups. Sixteen subjects with intellectual and developmental disabilities were randomized to overnight or gradual conversion for 4 to 6 days. A blinded rater completed the Multidimensional Observation Scale for Elderly Subjects on days +1, +4, and +8 after the switch began. We found no major differences between the 2 groups at each time point. Neither group of subjects, except for 1 subject in the overnight group, manifested sedation, seizures, worsening of tremor, or gastrointestinal adverse events. One subject in the overnight group manifested acute diarrhea and vomiting, followed by a very brief tonic leg seizure 6 days later. Larger studies are warranted. PMID:19745651

Effects of early and late rest breaks during training on overnight memory consolidation of a keyboard melody.  

PubMed

In two experiments, we tested the extent to which overnight procedural memory consolidation is affected by extended rest breaks during training. In the first experiment, nonmusicians practiced a 5-element keypress sequence with their nondominant hand in 12 30-s practice intervals separated by 30-s pauses. In the second experiment, nonpianist musicians practiced a 13-note keyboard melody using the same procedures. In both experiments, approximately one-third of the subjects took a 5-min break after the first three blocks of practice; another third took a break after nine blocks of practice; the remaining participants did not take an extended break. All were trained in the evening and were retested the following morning. Participants in both experiments made dramatic improvements over the course of the training and retest sessions, and participants who took an extended rest break early in practice made the largest gains in performance between the end of training and the beginning of retest.

The effect of microgravity on the fragrance of a miniature rose, ``Overnight Scentsation™'' on Space Shuttle (STS-95)  

NASA Astrophysics Data System (ADS)

To evaluate the effects of microgravity on the production of aroma constituents, the OVERNIGHT SCENTSATION™ rose plant with both an unopened bud and a half bloom was sent into the space aboard NASA space shuttle STS-95 for 9 days, from October 29 through November 6, 1998. While the flower was blooming in space, it was analyzed over four consecutive days using IFF's proprietary Solid Phase Micro Extraction (SPME) method. After returning to Earth on November 6, the information collected in space was analyzed and compared with the data collected from the same type of rose plant on the ground. The comparative results of the space rose and the Earth rose showed a drastic difference in their fragrance molecules. .

Evaluation of flavonoids and enterolactone in overnight urine as intake biomarkers of fruits, vegetables and beverages in the Inter99 cohort study using the method of triads.  

PubMed

Since collection of 24 h urine samples is very time consuming and difficult to obtain, epidemiological studies typically only obtain spot urine samples. The aim of the present study was to evaluate whether flavonoids and enterolactone in overnight urine could substitute flavonoids and enterolactone in 24 h urine as an alternative and more feasible biomarker of fruit, vegetable and beverage intake. A total of 191 individuals in the Inter99 cohort in Denmark completed the validation study. Concentrations of nine urinary flavonoid aglycones (quercetin, isorhamnetin, tamarixetin, kaempferol, hesperetin, naringenin, eriodictyol, phloretin and apigenin) and enterolactone were determined in overnight and 24 h urine samples, and their validity as biomarkers of fruit, vegetable and beverage intake was evaluated in relation to two independent reference methods (Inter99 FFQ data and plasma carotenoids) by using the method of triads. The intakes of fruit, juice, vegetables and tea reported in the FFQ were reflected by the flavonoid biomarker both in overnight and 24 h urine samples. Validity coefficients for the flavonoid biomarker in overnight urine ranged from 0·39 to 0·49, while the corresponding validity coefficients for the biomarker in 24 h urine ranged from 0·43 to 0·66. Although the validity coefficients were lower for overnight urine than for the 24 h urine flavonoid biomarker, they were still of acceptable magnitude. In conclusion, the results indicate that flavonoids and enterolactone in overnight urine samples may be used as a more feasible biomarker than 24 h urine for the assessment and validation of fruit, juice, vegetable and tea intakes in epidemiological studies.

Hand-held multiple system gas chromatograph  

DOEpatents

A multiple parallel hand-held gas chromatograph (GC) system which includes several independent GCs. Each independent GC has its own injector, separation column, detector and oven and the GCs are mounted in a light weight hand-held assembly. Each GC operates independently and simultaneously. Because of different coatings in different separation columns, different retention times for the same gas will be measured. Thus, for a GC system with multiple parallel GCs, the system can measure, in a short period, different retention times and provide a cross-reference in the determination of the measured gas and to become a two-dimensional system for direct field use.

Metabolomic and transcriptomic changes induced by overnight (16 h) fasting in male and female Sprague-Dawley rats.  

PubMed

The overnight (16-h) fast is one of the most common experimental manipulations performed in rodent studies. Despite its ubiquitous employment, a comprehensive evaluation of metabolomic and transcriptomic sequelae of fasting in conjunction with routine clinical pathology evaluation has not been undertaken. This study assessed the impact of a 16-h fast on urine and serum metabolic profiles, transcript profiles of liver, psoas muscle, and jejunum as well as on routine laboratory clinical pathology parameters. Fasting rats had an approximate 12% relative weight decrease compared to ad libitum fed animals, and urine volume was significantly increased. Fasting had no effect on hematology parameters, though several changes were evident in serum and urine clinical chemistry data. In general, metabolic changes in biofluids were modest in magnitude but broad in extent, with a majority of measured urinary metabolites and from 1/3 to 1/2 of monitored serum metabolites significantly affected. Increases in fatty acids and bile acids dominated the upregulated metabolites. Downregulated serum metabolites were dominated by diet-derived and/or gut-microflora derived metabolites. Major transcriptional changes included genes with roles in fatty acid, carbohydrate, cholesterol, and bile acid metabolism indicating decreased activity in glycolytic pathways and a shift toward increased utilization of fatty acids. Typically, several genes within these metabolic pathways, including key rate limiting genes, changed simultaneously, and those changes were frequently correlative to changes in clinical pathology parameters or metabolomic data. Importantly, up- or down-regulation of a variety of cytochrome P450s, transporters, and transferases was evident. Taken together, these data indicate profound consequences of fasting on systemic biochemistry and raise the potential for unanticipated interactions, particularly when metabolomic or transcriptomic data are primary end points.

Meta-Analysis of Overnight Closed-Loop Randomized Studies in Children and Adults with Type 1 Diabetes: The Cambridge Cohort  

PubMed Central

Aim We reviewed the safety and efficacy of overnight closed-loop insulin delivery compared with conventional continuous subcutaneous insulin infusion (CSII) in two distinct age groups with type 1 diabetes mellitus (T1DM), young people aged 5 to 18 years and adults, combining data of previously published randomized studies. Methods We evaluated four randomized crossover studies in 17 children and adolescents [13.4 ± 3.6 years; mean ± standard deviation (SD)] and 24 adults (37.5 ± 9.1 years) on 45 closed-loop (intervention) and 45 CSII (control) visits. Each subject attended for two overnight study visits, using either closed-loop or conventional pump therapy, in random order. In each age group, studies were designed to mimic realistic likely scenarios. In the children and adolescent studies, closed loop was used following a standard evening meal and following 40 min of moderate-intensity exercise. In the adult studies, closed loop was commenced following a 60 g carbohydrate meal or a 100 g carbohydrate meal accompanied by alcohol. The primary outcome measure was time for which plasma glucose was within target range (3.91–8.0 mmol/liter). Results Overnight closed loop increased the time in target plasma glucose in both young (from 40% to 60%, p = .002) and adults (from 50% to 76%, p < .001) compared with conventional CSII. Combined analysis showed an increase from 43% to 71% with closed loop (p < .001). Additionally, closed loop reduced the time spent below 3.91 mmol/liter and above 8.0 mmol/liter, from 4.1% to 2.1% (p = .01) and 33% to 20% (p = .03), respectively. Glycemic variability, as measured by the SD of plasma glucose, was lower during closed loop compared with CSII (1.5 versus 2.1 mmol/liter, p = .007). Conclusions Overnight closed loop may improve glycemic control and reduce nocturnal hypoglycemia in both young people and adults with T1DM.

Eszopiclone Improves Overnight Polysomnography and Continuous Positive Airway Pressure Titration: A Prospective, Randomized, Placebo-Controlled Trial  

PubMed Central

Study Objectives: To assess whether premedication with eszopiclone would improve sleep duration and continuity during polysomnography, thereby improving the quality of diagnostic and CPAP titration studies. Design: Prospective, double-blinded, placebo-controlled trial Setting: Academic, multidisciplinary sleep center. Patients: 226 adult subjects undergoing polysomnography for suspected sleep disordered breathing; 113 received eszopiclone and 113 received placebo. Interventions: Subjects received eszopiclone 3 mg or matching placebo before polysomnography. We compared sleep latency, efficiency, total sleep time, and apnea-hypopnea index between these groups. We also compared rates of inadequate studies, defined as insufficient sleep time (< 120 min or sleep efficiency ? 70%) or incomplete CPAP titrations (? 5 events/h on the highest CPAP or complete intolerance). Measurements and Results: Eszopiclone premedication significantly improved a number of measured variables. Eszopiclone reduced sleep latency (21.7 ± 27.1 vs. 32.6 ± 38.2 min, P = 0.014), improved sleep efficiency (87.6% ± 10.8% vs. 78.1% ± 15.6%, P < 0.001), reduced wake after sleep onset (39.2 ± 31.9 vs. 64.5 ± 45.4 min, P < 0.001) and prolonged sleep time (346.5 ± 53.1 vs. 312.2 ± 64.2 min, P < 0.001). Sleep efficiencies ? 70% were more common with placebo than medication (21.2% vs. 7.1%, P = 0.004). Eszopiclone facilitated improved CPAP titrations with fewer residual events (5.7 ± 10.3 vs. 11.9 ± 19.6, P = 0.02) and fewer incomplete titrations (31.1% vs. 48.0%, P = 0.04). Poor quality studies (46.0% vs. 26.5%, P = 0.004) were more common with placebo than with eszopiclone. There was a trend for more non-usable studies with placebo (7.1% vs. 2.7%, P = 0.22). Side effects were uncommon and did not differ between groups. Conclusion: Pretreatment with eszopiclone improves the quality of polysomnography and CPAP titration and decreases the need to repeat studies. Given the ever-growing demand for polysomnography and the need to improve efficiency, the routine use of nonbenzodiazepines as premedication for polysomnography should be considered.

Digital hand-held temperature monitor  

NASA Astrophysics Data System (ADS)

A hand-held non-invasive monitoring instrument has been designed, constructed and tested to allow core temperature measurements to be obtained from human subjects who have swallowed a temperature-sensing radio transmitter (radio pill). This instrument uses a simple AM radio for a receiver, digital circuitry to decode the received signal and a four-digit LED module to display the temperature. The unit, which is battery-powered, can be held in one hand while an antenna probe is swept over the abdomen of the subject until a continuously audible signal is generated by a piezoelectric sound source, indicating reception. The digital display then presents the body core temperature in tenths of a degree Celsius.

Land Subsidence International Symposium held in Venice  

NASA Astrophysics Data System (ADS)

The Third International Symposium on Land Subsidence was held March 18-25, 1984, in Venice, Italy. Sponsors were the Ground-Water Commission of the International Association of Hydrological Sciences (IAHS), the United Nations Educational, Scientific, and Cultural Organization (UNESCO), the Italian National Research Council (CNR), the Italian Regions of Veneto and Emilia-Romagna, the Italian Municipalities of Venice, Ravenna, and Modena, the Venice Province, and the European Research Office. Cosponsors included the International Association of Hydrogeologists (IAH), the International Society for Soil Mechanics and Foundation Engineering (ISSMFE), and the Association of Geoscientists for International Development (AGID).Organized within the framework of UNESCO's International Hydrological Program, the symposium brought together over 200 international interdisciplinary specialists in the problems of land subsidence due to fluid and mineral withdrawal. Because man's continuing heavy development of groundwater, gas, oil, and minerals is changing the natural regime and thus causing more and more subsiding areas in the world, there had been sufficient new land subsidence occurrence, problems, research, and remedial measures since the 1976 Second International Symposium held in Anaheim, California, to develop a most interesting program of nearly 100 papers from about 30 countries. The program consisted of papers covering case histories of fluid and mineral withdrawal, engineering theory and analysis, karst “sink-hole”-type subsidence, subsidence due to dewatering of organic deposits or due to application of water (hydrocompaction), instrumentation, legal, socioeconomic, and environmental effects of land subsidence, and remedial works.

Should we do an oral glucose tolerance test in hypertensive men with normal fasting blood-glucose?  

Microsoft Academic Search

The objective of this study was to examine, using the new WHO criteria for diabetes mellitus, whether insulin and glucose before and after an oral glucose tolerance test would predict cardiovascular mortality in hypertensive men with normal fasting blood glucose. A standard oral glucose challenge was performed after an overnight fast in 113 hypertensive men with either hypercholesterolaemia or smoking.

Noninvasive Measurement of Murine Hepatic Acetyl-CoA 13C-Enrichment Following Overnight Feeding with 13C-Enriched Fructose and Glucose  

PubMed Central

The 13C-isotopomer enrichment of hepatic cytosolic acetyl-CoA of overnight-fed mice whose drinking water was supplemented with [U-13C]fructose, and [1-13C]glucose and p-amino benzoic acid (PABA) was quantified by 13C NMR analysis of urinary N-acetyl-PABA. Four mice were given normal chow plus drinking water supplemented with 5% [1-13C]glucose, 2.5% [U-13C]fructose, and 2.5% fructose (Solution 1) overnight. Four were given chow and water containing 17.5% [1-13C]glucose, 8.75% [U-13C]fructose and 8.75% fructose (Solution 2). PABA (0.25%) was present in both studies. Urinary N-acetyl-PABA was analyzed by 13C NMR. In addition to [2-13C]- and [1,2-13C]acetyl isotopomers from catabolism of [U-13C]fructose and [1-13C]glucose to acetyl-CoA, [1-13C]acetyl was also found indicating pyruvate recycling activity. This precluded precise estimates of [1-13C]glucose contribution to acetyl-CoA while that of [U-13C]fructose was unaffected. The fructose contribution to acetyl-CoA from Solutions 1 and 2 was 4.0 ± 0.4% and 10.6 ± 0.6%, respectively, indicating that it contributed to a minor fraction of lipogenic acetyl-CoA under these conditions.

An online failure detection method of the glucose sensor-insulin pump system: improved overnight safety of type-1 diabetic subjects.  

PubMed

Sensors for real-time continuous glucose monitoring (CGM) and pumps for continuous subcutaneous insulin infusion (CSII) have opened new scenarios for Type-1 diabetes treatment. However, occasional failures of either CGM or CSII may expose diabetic patients to possibly severe risks, especially overnight (e.g., inappropriate insulin administration). In this contribution, we present a method to detect in real time such failures by simultaneously using CGM and CSII data streams and a black-box model of the glucose-insulin system. First, an individualized state-space model of the glucose-insulin system is identified offline from CGM and CSII data collected during a previous monitoring. Then, this model, CGM and CSII real-time data streams are used online to obtain predictions of future glucose concentrations together with their confidence intervals by exploiting a Kalman filtering approach. If glucose values measured by the CGM sensor are not consistent with the predictions, a failure alert is generated in order to mitigate the risks for patient safety. The method is tested on 100 virtual patients created by using the UVA/Padova Type-1 diabetic simulator. Three different types of failures have been simulated: spike in the CGM profile, loss of sensitivity of glucose sensor, and failure in the pump delivery of insulin. Results show that, in all cases, the method is able to correctly generate alerts, with a very limited number of false negatives and a number of false positives, on average, lower than 10%. The use of the method in three subjects supports the simulation results, demonstrating that the accuracy of the method in generating alerts in presence of failures of the CGM sensor-CSII pump system can significantly improve safety of Type-1 diabetic patients overnight.

Practical applications of hand-held computers in dermatology.  

PubMed

For physicians, hand-held computers are gaining popularity as point of care reference tools. The convergence of hand-held computers, the Internet, and wireless networks will enable these devices to assume more essential roles as mobile transmitters and receivers of digital medical Information. In addition to serving as portable medical reference sources, these devices can be Internet-enabled, allowing them to communicate over wireless wide and local area networks. With enhanced wireless connectivity, hand-held computers can be used at the point of patient care for charge capture, electronic prescribing, laboratory test ordering, laboratory result retrieval, web access, e-mail communication, and other clinical and administrative tasks. Physicians In virtually every medical specialty have begun using these devices in various ways. This review of hand-held computer use in dermatology illustrates practical examples of the many different ways hand-held computers can be effectively used by the practicing dermatologist.

Overnight ACTH-Cortisol Dose-Responsiveness: comparison with 24-hr data, metyrapone administration, and insulin-tolerance test in healthy adults  

PubMed Central

Objective To estimate the dose-dependence of endogenous ACTH’s stimulation of adrenal cortisol secretion overnight. Design Ten-minute sampling for ACTH and cortisol over 8 and 24 hr (N=17), after metyrapone administration (N=6), during an insulin tolerance test (N=7). Subjects Healthy adults. Measurements ACTH dose-responsive estimates. Results Twenty-four hr ACTH-cortisol concentration pairs yielded an estimated EC50 (one-half maximally stimulatory ACTH concentration) of 5.1 (2.2–9.5) pmol/L [median (range)]. This did not differ from EC50’s based upon 8 or 6-hr data [5.9 (3.5–11) and 7.5 (3.7–41) pmol/L] in the same individuals. ACTH efficacy (maximally stimulatable cortisol secretion rate) was 8.4 (3.1–20), 11 (5.9–24) and 15 (5.9–22) nmol/L/min, when calculated over 24, 8 and 6 hr, respectively (P=NS). Adrenal sensitivity (slope term) was also consistent across sampling durations, viz., 14 (1.3–95), 18 (1.3–64) and 20 (1.3–64) slope units. Compared with placebo, metyrapone reduced ACTH efficacy from 11 (6.2–62) to 2.8 (1.5–4.5) nmol/L/min for cortisol (N=9, P<0.001), while increasing ACTH efficacy for 11-desoxycortisol from 2.3 (0.9–2.9) to 99 (70–218) nmol/L/min (N=6, P<0.01), thus affirming face validity. Combined ACTH and cortisol responses to hypoglycemia allowed an estimate of ACTH efficacy of 28 (22–81) nmol/L/min, compared with the control value of 8.7 (5.6–26), suggesting enhanced adrenal responsiveness. Conclusions The results suggest that endogenous ACTH-adrenal drive can be approximated from overnight 8-hr sampling of paired ACTH and cortisol concentrations. This strategy may have merit in clinical research in childhood, pregnancy, anxiety states, and frail elderly individuals, when ACTH injections are not desired.

How well are parent held records kept and completed?  

PubMed Central

During 1986 and 1987 parents in part of the Oxfordshire district health authority were given their child's health and development records while in the other part of the health district the records remained with the clinic. Between August 1988 and February 1989 an audit was made of a sample of parents attending child health clinics in the two areas: the study examined 284 parents who had parent held records and 168 who did not; how many records were available and if not, why not; how well and by whom records were completed and parents' views on who they felt should keep the record. Interviews revealed that parents with a parent held record liked the scheme and were confident about remembering to take the record to the clinic. Those without experience were less confident and more concerned about losing the record. At the time of the audit 7% of parent held records had been lost or forgotten, but 5% of clinic held records were not available for inspection. Overall, parent held records were more likely to have comments contributed by parents and to be more thoroughly completed by professionals. The results suggest that parent held records are not only workable but desirable.

How To Eliminate Narcissism Overnight  

PubMed Central

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition appears likely to eliminate the diagnosis of narcissistic personality disorder. There are significant problems with the discriminant validity of the current narcissistic personality disorder critiera set; furthermore, the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition's narrow focus on “grandiosity” probably contributes to the wide disparity between low narcissistic personality disorder prevalence rates in epidemiological studies and high rates of narcissistic personality disorder in clinical practice. Nevertheless, the best course of action may be to refine the narcissistic personality disorder criteria, followed by careful field testing and a search for biomarkers, rather than wholesale elimination of the narcissistic personality disorder category. The construct of “malignant narcissism” is also worthy of more intense empirical investigation.

Outcomes in 125 individuals with adrenal incidentalomas from a single centre. a retrospective assessment of the 1?mg overnight and low dose dexamethasone suppression tests.  

PubMed

Adrenal masses discovered incidentally during imaging studies - adrenal incidentalomas (AIs) - are common and prompt investigations to exclude secretory lesions and malignancy. Their best management strategy is unknown. Our objectives were to identify all outcomes of AI investigation in a UK centre and to assess the performance of the 2?mg low dose (LDDST) and 1?mg overnight dexamethasone (ODST) suppression tests in this setting. Out of 125 patients referred to our centre between 2005 and 2009 with AIs, 16 (12.8%) were diagnosed with secretory adrenal adenomas. 24 patients (23%) failed to suppress on LDDST or ODST using a serum cortisol cut-off of 50?nmol/l for both tests; in 12 this was due to false positive results. 5 patients were diagnosed with adrenal Cushing's syndrome and 7 with subclinical hypercortisolism. The use of a higher post LDDST (83?nmol/l) or ODST (138?nmol/l) cortisol cut-off would have resulted in missing 1 patient with Cushing's syndrome and 4 with subclinical hypercortisolism or 2 patients with Cushing's syndrome and 1 with subclinical hypercortisolism, respectively. In patients who had both tests, the ODST systematically resulted in higher post-test cortisol values compared with the LDDST. The adenoma diameter correlated with and was predictive of the post LDDST cortisol. Our results indicate that altering the post dexamethasone cut-off in accordance to published guidelines changes the performance of the suppression tests. The ODST may result in higher post-test cortisol levels compared to LDDST when used in patients with AIs. PMID:22048862

Overnight culture unmasks glucose-induced insulin secretion in mouse islets lacking ATP-sensitive K+ channels by improving the triggering Ca2+ signal.  

PubMed

A current model ascribes glucose-induced insulin secretion to the interaction of a triggering pathway (K(ATP) channel-dependent Ca(2+) influx and rise in cytosolic [Ca(2+)](c)) and an amplifying pathway (K(ATP) channel-independent augmentation of secretion without further increase of [Ca(2+)](c)). However, several studies of sulfonylurea receptor 1 null mice (Sur1KO) failed to measure significant effects of glucose in their islets lacking K(ATP) channels. We addressed this issue that challenges the model. Compared with controls, fresh Sur1KO islets showed slightly elevated basal [Ca(2+)](c) and insulin secretion. In 15 mm glucose, the absolute rate of secretion was approximately 3-fold lower in Sur1KO than control islets, with only poor increase above base line. Overnight culture of Sur1KO islets in 10 mm glucose (not in 5 mm) augmented basal insulin secretion and considerably improved the response to 15 mm glucose, which reached higher values than in control islets, in which culture had little impact. Glucose stimulation during KCl depolarization showed that the amplifying pathway is functional in fresh and cultured Sur1KO islets. The differences in insulin secretion between fresh and cultured Sur1KO islets and between Sur1KO and control islets were not attributable to differences in insulin content, glucose oxidation rate, or synchronization of [Ca(2+)](c) oscillations. The unmasking of glucose-induced insulin secretion in beta-cells lacking K(ATP) channels is paradoxically due to improvement in the production of a triggering signal (elevated [Ca(2+)](c)). The results show that K(ATP) channels are not the only transducer of glucose effects on [Ca(2+)](c) in beta-cells. They explain controversies in the literature and refute arguments raised against the model implicating an amplifying pathway in glucose-induced insulin secretion. PMID:17389589

Artificial blood  

PubMed Central

Artificial blood is a product made to act as a substitute for red blood cells. While true blood serves many different functions, artificial blood is designed for the sole purpose of transporting oxygen and carbon dioxide throughout the body. Depending on the type of artificial blood, it can be produced in different ways using synthetic production, chemical isolation, or recombinant biochemical technology. Development of the first blood substitutes dates back to the early 1600s, and the search for the ideal blood substitute continues. Various manufacturers have products in clinical trials; however, no truly safe and effective artificial blood product is currently marketed. It is anticipated that when an artificial blood product is available, it will have annual sales of over $7.6 billion in the United States alone.

Wet With Blood  

NSDL National Science Digital Library

The Chicago Historical Society (CHS) and Northwestern University have recently unveiled this fine online exhibit. The site is an interesting example of how contemporary scientific research methods (specifically DNA forensics) can be used to help solve the problem of authentication of historical museum objects. Conceived and created by the Textile Curator of the CHS, the site traces ongoing efforts made to authenticate blood stains on a cloak belonging to Mary Todd Lincoln and other Lincoln assassination relics held by the CHS. It offers a review of both these relics and their provenance and the scientific methods used, as well as QuickTime movies of the experts in action, and a QTVR tour of the textile conservation lab. In all, an interesting and surprisingly detailed look at the merger of history and forensic science.

Engineering issues for hand-held sensing devices, with examples  

NASA Astrophysics Data System (ADS)

It is now U.S. defense policy that there will be no new platform starts. The emphasis for platforms will be on O&M cost reduction, life-extension improvements, and force-multiplier- device upgrades. There is also an increasing emphasis on hand-held force-multiplier devices for individuals, which is the focus of this paper. Engineering issues include operations analysis, weight, cube, cost, prime power, ease of use, data storage, reliability, fault tolerance, data communications and human factors. Two examples of hand-held devices are given. Applications include USMC, Army, SOCOM, DEA, FBI, SS, Border Patrol and others. Barriers to adoption of such technology are also discussed.

A First Look at Mobile Hand-Held Device Traffic  

NASA Astrophysics Data System (ADS)

Although mobile hand-held devices (MHDs) are ubiquitous today, little is know about how they are used - especially at home. In this paper, we cast a first look on mobile hand-held device usage from a network perspective. We base our study on anonymized packet level data representing more than 20,000 residential DSL customers. Our characterization of the traffic shows that MHDs are active on up to 3% of the monitored DSL lines. Mobile devices from Apple (i.e., iPhones and iPods) are, by a huge margin, the most commonly used MHDs and account for most of the traffic. We find that MHD traffic is dominated by multimedia content and downloads of mobile applications.

Formation and Maturation of the Calyx of Held  

PubMed Central

Sound localization requires precise and specialized neural circuitry. A prominent and well-studied specialization is found in the mammalian auditory brainstem. Globular bushy cells of the ventral cochlear nucleus (VCN) project contralaterally to neurons of the medial nucleus of the trapezoid body (MNTB), where their large axons terminate on cell bodies of MNTB principal neurons, forming the calyces of Held. The VCN-MNTB pathway is necessary for the accurate computation of interaural intensity and time differences; MNTB neurons provide inhibitory input to the lateral superior olive, which compares levels of excitation from the ipsilateral ear to levels of tonotopically matched inhibition from the contralateral ear, and to the medial superior olive, where precise inhibition from MNTB neurons tunes the delays of binaural excitation. Here we review the morphological and physiological aspects of the development of the VCN-MNTB pathway and its calyceal termination, along with potential mechanisms that give rise to its precision. During embryonic development, VCN axons grow towards the midline, cross the midline into the region of the presumptive MNTB and then form collateral branches that will terminate in calyces of Held. In rodents, immature calyces of Held appear in MNTB during the first few days of postnatal life. These calyces mature morphologically and physiologically over the next three postnatal weeks, enabling fast, high fidelity transmission in the VCN-MNTB pathway.

Promoting Physical Activity through Hand-Held Computer Technology  

PubMed Central

Background Efforts to achieve population-wide increases in walking and similar moderate-intensity physical activities potentially can be enhanced through relevant applications of state-of-the-art interactive communication technologies. Yet few systematic efforts to evaluate the efficacy of hand-held computers and similar devices for enhancing physical activity levels have occurred. The purpose of this first-generation study was to evaluate the efficacy of a hand-held computer (i.e., personal digital assistant [PDA]) for increasing moderate intensity or more vigorous (MOD+) physical activity levels over 8 weeks in mid-life and older adults relative to a standard information control arm. Design Randomized, controlled 8-week experiment. Data were collected in 2005 and analyzed in 2006-2007. Setting/Participants Community-based study of 37 healthy, initially underactive adults aged 50 years and older who were randomized and completed the 8-week study (intervention=19, control=18). Intervention Participants received an instructional session and a PDA programmed to monitor their physical activity levels twice per day and provide daily and weekly individualized feedback, goal setting, and support. Controls received standard, age-appropriate written physical activity educational materials. Main Outcome Measure Physical activity was assessed via the Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire at baseline and 8 weeks. Results Relative to controls, intervention participants reported significantly greater 8-week mean estimated caloric expenditure levels and minutes per week in MOD+ activity (p<0.04). Satisfaction with the PDA was reasonably high in this largely PDA-naive sample. Conclusions Results from this first-generation study indicate that hand-held computers may be effective tools for increasing initial physical activity levels among underactive adults.

Bacterial lipopolysaccharide mediates the loss of CD4 from the surface of purified peripheral blood monocytes.  

PubMed Central

In this study we have looked at the effect of lipopolysaccharide (LPS) on the surface antigen expression of cultured monocytes. Monocytes were purified from peripheral blood mononuclear cells (PBMC) and cultured in the presence or absence of LPS. The cultured cells were then stained with anti-MO3, anti-IL-2R and anti-CD4 MoAbs. We have shown that freshly isolated monocytes are IL-2R- and MO3-negative and express CD4 in low density. After overnight culture, without LPS, the expression of these surface markers remained relatively unchanged. However, in the presence of LPS (1 microgram/ml) CD4 expression was reduced to undetectable levels while the expression of IL-2R and MO3 was induced to maximal density. This effect of LPS on monocyte surface antigen expression was demonstrated with LPS preparations from Escherichia coli, Salmonella typhi and Vibrio cholerae. Surface antigen expression after 7 days culture in medium supplemented with non-heat-inactivated serum was essentially as seen after overnight culture, with the exception that LPS-induced IL-2R expression was transient. The ability to prepare monocytes that maintained surface CD4 expression after overnight culture was donor dependent. Images Fig. 5

[Effect of altitude on blood oxygenation during sleep in patients with bronchial asthma].  

PubMed

The aim of our study was to investigate the severity of overnight arterial blood desaturations in patients with asthma at the altitude of 3200 meters above sea level. 12 asthmatics and 12 healthy controls were investigated. Three overnight pulsoximetries were performed in all subjects, one at the lowland and on the 1st and 5th night at the altitude. Mean SaO2 at the lowland was significantly lower in asthmatics than in the controls (p < 0.01). After the ascent to high altitude severe fall in mean SaO2 was noted in both groups (from 94.3% to 85.8% in asthmatics and from 97.1% to 88.7% in controls) (p < 0.001 for both groups). After few days of acclimatization mean SaO2 rose to 88.8% in asthmatics and to 91.3% in controls, but was still significantly lower than at the lowland (p < 0.001 for both groups). At the altitude differences in mean SaO2 between two groups were not statistically significant. We conclude that severity of overnight desaturations at high altitude do not vary between asthmatics with impaired respiratory function and healthy subjects. PMID:8991562

Correlations between blood glucose and breath components from portable gas sensors and PTR-TOF-MS.  

PubMed

Acetone is one of the most abundant volatile compounds in the human breath and might be important for monitoring diabetic patients. Here, a portable acetone sensor consisting of flame-made, nanostructured, Si-doped WO3 sensing films was used to analyse the end tidal fraction of the breath (collected in Tedlar bags) from eight healthy volunteers after overnight fasting (morning) and after lunch (afternoon). After breath sampling, the gaseous components were also analysed by proton transfer reaction time-of-flight mass spectrometry (PTR-TOF-MS), and each person's blood glucose level was measured. The portable sensor accurately detected the presence of acetone with fast response/recovery times (<12 s) and a high signal-to-noise ratio. Statistical analysis of the relationship between the PTR-TOF-MS measurements of breath gases (e.g., acetone, isoprene, ethanol and methanol), sensor response and the blood glucose level was performed for both sampling periods. The best correlations were found after overnight fasting (morning): in particular, between blood glucose level and breath acetone (Pearson's 0.98 and Spearman's 0.93). Whereas the portable sensor response correlated best with the blood glucose (Pearson's 0.96 and Spearman's 0.81) and breath acetone (Pearson's 0.92 and Spearman's 0.69). PMID:23959908

Bone age maturity assessment using hand-held device  

NASA Astrophysics Data System (ADS)

Purpose: Assessment of bone maturity is traditionally performed through visual comparison of hand and wrist radiograph with existing reference images in textbooks. Our goal was to develop a digital index based on idealized hand Xray images that can be incorporated in a hand held computer and used for visual assessment of bone age for patients. Material and methods: Due to the large variability in bone maturation in normals, we generated a set of "ideal" images obtained by computer combinations of images from our normal reference data sets. Software for hand-held PDA devices was developed for easy navigation through the set of images and visual selection of matching images. A formula based on our statistical analysis provides the standard deviation from normal based on the chronological age of the patient. The accuracy of the program was compared to traditional interpretation by two radiologists in a double blind reading of 200 normal Caucasian children (100 boys, 100 girls). Results: Strong correlations were present between chronological age and bone age (r > 0.9) with no statistical difference between the digital and traditional assessment methods. Determinations of carpal bone maturity in adolescents was slightly more accurate using the digital system. The users did praise the convenience and effectiveness of the digital Palm Index in clinical practice. Conclusion: An idealized digital Palm Bone Age Index provides a convenient and effective alternative to conventional atlases for the assessment of skeletal maturity.

Ultratrace detector for hand-held gas chromatography  

DOEpatents

An ultratrace detector system for hand-held gas chromatography having high sensitivity, for example, to emissions generated during production of weapons, biological compounds, drugs, etc. The detector system is insensitive to water, air, helium, argon, oxygen, and C0.sub.2. The detector system is basically composed of a hand-held capillary gas chromatography (GC), an insulated heated redox-chamber, a detection chamber, and a vapor trap. For example, the detector system may use gas phase redox reactions and spectral absorption of mercury vapor. The gas chromatograph initially separates compounds that percolate through a bed of heated mercuric oxide (HgO) in a silica--or other metal--aerogel material which acts as an insulator. Compounds easily oxidized by HgO liberate atomic mercury that subsequently pass through a detection chamber which includes a detector cell, such as quartz, that is illuminated with a 254 nm ultra-violet (UV) mercury discharge lamp which generates the exact mercury absorption bands that are used to detect the liberated mercury atoms. Atomic mercury strongly absorbs 254 nm energy is therefore a specific signal for reducing compounds eluting from the capillary GC, whereafter the atomic mercury is trapped for example, in a silicon-aerogel trap.

Third Space Weather Summit Held for Industry and Government Agencies  

NASA Astrophysics Data System (ADS)

The potential for space weather effects has been increasing significantly in recent years. For instance, in 2008 airlines flew about 8000 transpolar flights, which experience greater exposure to space weather than nontranspolar flights. This is up from 368 transpolar flights in 2000, and the number of such flights is expected to continue to grow. Transpolar flights are just one example of the diverse technologies susceptible to space weather effects identified by the National Research Council's Severe Space Weather Events—Understanding Societal and Economic Impacts: A Workshop Report (2008). To discuss issues related to the increasing need for reliable space weather information, experts from industry and government agencies met at the third summit of the Commercial Space Weather Interest Group (CSWIG) and the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center (SWPC), held 30 April 2009 during Space Weather Week (SWW), in Boulder, Colo.

Evaluation of ultrasound lung comets by hand-held echocardiography  

PubMed Central

Background Ultrasound lung comets (ULCs) are a clinically useful sign of extravascular lung water. They require very limited technology (2 D-echo), and a short learning curve. The aim of the present study is to compare ULCs information obtained by experienced echocardiologists using a full feature echocardiographic platform and by inexperienced sonographers using a hand-held echocardiography system. Methods 20 consecutive in-hospital patients underwent, within 15' and in random order, 2 ultrasound examinations for ULCs by 2 observers with different specific expertise and different technology: 1) "high-tech veteran": ULCs assessment with full feature echocardiographic platform (HP Sonos 7500 Philips Medical Systems, Andover, MA, USA) by a trained echocardiologist, with ?2 years expertise in ULCs assessment and accredited by the European Association of Echocardiography; 2) and a "low-tech beginner": ULCs assessment with hand-held echocardiography (Optigo; Philips, Andover, MA) by an echocardiographer with very limited (30') dedicated training on ULCs assessment. In each patient, ULC score was obtained by summing the number of comets from each of the scanning spaces in the anterior right and left hemithorax, from the second to the fifth intercostal space. Results There was a significant, tight correlation (r = .958, p < 0.001) between the 2 observations in the same patient by "high-tech veteran" and "low-tech beginner". Conclusion ULCs are equally reliable in the hands of highly experienced echocardiologists using full feature echocardiographic platforms and in the hands of absolute beginners with miniaturized, compact, and battery-equipped echocardiographic systems. From the technological and expertise viewpoint, ULCs are the "kindergarten" of echocardiography, ideally suited for bedside evaluation of patients with both known or suspected heart failure.

Long-term performance of a hand held spirometer.  

PubMed Central

BACKGROUND: A study was undertaken to test the long term performance of a small hand held spirometer for self-administered serial spirometric testing. METHODS: Thirty turbine pocket spirometers (MicroMedical DiaryCard) were used in a clinical trial on 22 emphysematous patients with severe alpha 1-antitrypsin deficiency. The spirometers were able to store the date, time, forced expiratory volume in one second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), and flow-volume loop for each blow. Every four weeks when the patients came for alpha 1-antitrypsin infusions the performance of their spirometer was checked before and after retrieval of the data from the spirometer. Calibration checks were threefold and included volume calibration with a 1.0 litre and 3.0 litre syringe, and flow calibration with a decompression calibrator. RESULTS: After two years of study the mean number of spirometric recordings performed per spirometer was 693 (range 237-1178), and the mean number of calibration checks was 33 (range 2-57). The coefficient of variation of the calibration signal was 1-2% for syringes and 0.5-1% for the decompression calibrator. The bearings of one turbine exhibited excessive friction after 17 months. None of the other 29 instruments showed drift, and a general drift of all spirometers towards larger or smaller readings could not be shown. However, unforeseen problems in the stability of the calibrating devices were observed. CONCLUSIONS: The small hand held turbine spirometers are suitable for long term patient-administered serial spirometric testing. The two year durability is acceptable and the long term reproducibility excellent.

Comparison of blood alcohol concentrations after beer and whiskey.  

PubMed

To determine whether blood alcohol concentrations achieved by ingestion of various alcoholic beverages differ as a function of prandial state, healthy male volunteers, aged 24 to 48 years, were given the same amount of alcohol (0.3 g/kg) as different beverages. The alcohol was consumed in three prandial states: postprandial (1 hr after a meal, n = 10), prandial (during the meal, n = 10), and preprandial (after an overnight fast, n = 9). Each subject was tested with both beer and whiskey, and in the postprandial state also with wine and sherry, in a within-subjects design. Blood alcohol concentrations were estimated by breath analysis for 4 hr or until concentrations reached zero. Peak blood alcohol levels were higher with beer than with whiskey in the postprandial and prandial conditions (p < 0.01), whereas the opposite was true in the preprandial state (p < 0.05). Similarly, the area under the blood alcohol curve was higher with beer in the prandial state (p < 0.05), and higher with whiskey in the preprandial condition (p < 0.01). Wine and sherry yielded peak concentrations intermediate between those of beer and whiskey in the postprandial state. The results indicate that a dilute alcoholic drink can yield either higher or lower blood alcohol levels than a concentrated beverage, depending on the prandial state. PMID:8333604

Blood transfusion: uses, abuses, and hazards.  

PubMed Central

Homologous blood transfusion without risk is an unobtainable goal. Infection with human immunodeficiency virus continues to occur at an average rate of one infection per 100,000 transfusions, in spite of the most sensitive and specific testing available. In the past 30 years, the number of red cell antigens identified have increased from primarily ABO and Rh to some 400 antigens, which has also contributed to the hazards of blood transfusion. These risks can be minimized by the judicious use of homologous blood in conjunction with technological advances in transfusion medicine therapy and changes in attitudes of transfusionists. In the operating theater, there has been a resurgence in intraoperative autologous transfusion therapy, and patients are individualized rather than held to an arbitrary hemoglobin standard prior to anesthesia. In the preoperative period, elective surgical candidates may predeposit autologous blood or select directed donors. The prospective recipient or the directed donor may be candidate for recombinant erythropoietin therapy as a prelude to blood donation. This article discusses the uses of blood and blood products, the hazards of blood transfusion, and precautions that can be taken to minimize risks to the patient.

Public eyewitness confidence ratings can differ from those held privately.  

PubMed

Despite much research on eyewitness confidence, we know very little about whether confidence ratings given in public might differ from those held privately. This study tested a prediction derived from self-presentation theory that eyewitnesses will give lower confidence ratings in public when there is a possibility of their account being contradicted by other witnesses as compared to when they report their confidence in private. In groups of 3 or 4 people, 96 participants watched a videotape of a simulated robbery and then answered 16 forced-choice questions about details from the videotape. In half of the experimental sessions, the participants shared their answers and confidence ratings aloud with the other participants (public condition), and in the other half, the answers and ratings were not shared (private). As predicted, confidence ratings were significantly lower in the public condition than in the private condition, but the privacy manipulation had no effect on response accuracy. These results are consistent with a self-presentation explanation, and they highlight the need to examine public confidence ratings more thoroughly. PMID:11419379

Stereo vision based hand-held laser scanning system design  

NASA Astrophysics Data System (ADS)

Although 3D scanning system is used more and more broadly in many fields, such computer animate, computer aided design, digital museums, and so on, a convenient scanning device is expansive for most people to afford. In another hand, imaging devices are becoming cheaper, a stereo vision system with two video cameras cost little. In this paper, a hand held laser scanning system is design based on stereo vision principle. The two video cameras are fixed tighter, and are all calibrated in advance. The scanned object attached with some coded markers is in front of the stereo system, and can be changed its position and direction freely upon the need of scanning. When scanning, the operator swept a line laser source, and projected it on the object. At the same time, the stereo vision system captured the projected lines, and reconstructed their 3D shapes. The code markers are used to translate the coordinate system between scanned points under different view. Two methods are used to get more accurate results. One is to use NURBS curves to interpolate the sections of the laser lines to obtain accurate central points, and a thin plate spline is used to approximate the central points, and so, an exact laser central line is got, which guards an accurate correspondence between tow cameras. Another way is to incorporate the constraint of laser swept plane on the reconstructed 3D curves by a PCA (Principle Component Analysis) algorithm, and more accurate results are obtained. Some examples are given to verify the system.

Cordless hand-held optical 3D sensor  

NASA Astrophysics Data System (ADS)

A new mobile optical 3D measurement system using phase correlation based fringe projection technique will be presented. The sensor consist of a digital projection unit and two cameras in a stereo arrangement, whereby both are battery powered. The data transfer to a base station will be done via WLAN. This gives the possibility to use the system in complicate, remote measurement situations, which are typical in archaeology and architecture. In the measurement procedure the sensor will be hand-held by the user, illuminating the object with a sequence of less than 10 fringe patterns, within a time below 200 ms. This short sequence duration was achieved by a new approach, which combines the epipolar constraint with robust phase correlation utilizing a pre-calibrated sensor head, containing two cameras and a digital fringe projector. Furthermore, the system can be utilized to acquire the all around shape of objects by using the phasogrammetric approach with virtual land marks introduced by the authors1, 2. This way no matching procedures or markers are necessary for the registration of multiple views, which makes the system very flexible in accomplishing different measurement tasks. The realized measurement field is approx. 100 mm up to 400 mm in diameter. The mobile character makes the measurement system useful for a wide range of applications in arts, architecture, archaeology and criminology, which will be shown in the paper.

The contribution of urinary cations to the blood pressure differences associated with migration.  

PubMed

People living in unacculturated societies have a low average blood pressure and little rise in blood pressure with age. In a community-based survey in southwestern China, the authors assessed the contribution of urinary cation excretion to differences in blood pressure between an unacculturated group (Yi farmers) and migrants to an urban environment, as well as urban controls from a different ethnic group (Han). In March 1989, blood pressure and overnight urinary electrolyte levels were measured on 3 consecutive days in 313 Yi farmers, 265 Yi migrants, and 253 urban Han residents, all male. Of the urinary electrolytes, a higher sodium:potassium ratio best explained the higher blood pressure in the migrants. Yi farmers had lower systolic (106.7 mmHg vs. 114.8 mmHg, respectively) and diastolic (66.2 mmHg vs. 71.3 mmHg, respectively) blood pressures than Yi migrants. However, even after adjustment for age, body mass index, alcohol intake, and urinary sodium, potassium, calcium, and magnesium excretion, Yi farmers continued to have lower average blood pressures than Yi migrants. In pooled analyses of all three groups, urinary sodium and calcium were positively related and urinary potassium and magnesium were inversely related to blood pressure. Migration is associated with a higher blood pressure that is only partially explained by higher levels of adiposity and alcohol and sodium intake and lower levels of potassium and magnesium intake.

Cannabichromene and tetrahydrocannabinol determination in mouse blood and brain by gas chromatography-mass spectrometry.  

PubMed

Cannabichromene (CBC) is a phytocannabinoid, the second most abundant cannabinoid quantitatively in marijuana. CBC has been shown to produce antinociception and anti-inflammatory effects in rodents. This method is validated for the measurement of THC and CBC simultaneously after extraction from mouse blood or brain. Whole brain harvested from mice was homogenized 2:1 (v/w) with normal saline. Fifty nanograms of THC-d? was added to 0.5 mL of heparinized mouse blood, brain homogenate, and THC and CBC fortified blood or brain calibrators, then equilibrated overnight at 5 °C. Two milliliters of "ice cold" acetonitrile was added drop-wise while the sample was vortex mixed, and then the sample was centrifuged and stored overnight at -30 °C. The cannabinoids were extracted from the acetonitrile layer with 2 mL of 0.2 N NaOH and 4 mL of hexane/ethyl acetate (9:1). The solvent was isolated and evaporated to dryness. Trimethylsilyl derivatives were prepared and then analyzed by gas chromatography-mass spectrometry. Linearity in blood and brain of THC and CBC was 2-10,000 ng/mL (ng/g). THC and CBC recovery ranged from 56 to 78% in blood and brain. Precision was demonstrated at 100 ng/mL and 1000 ng/mL with CVs < 15%. The validated method allows for blood and brain concentrations of cannabinoids to be quantificated and correlated with pharmacological effects produced in mice. PMID:21871159

Portable Hand-Held Electrochemical Sensor for the Transuranics  

SciTech Connect

During the four-year period of the grant all of the goals of the originally proposed work were achieved, and some additional accomplishments are here reported. Two types of sensors were designed and built in the lab, capable of detecting uranium, plutonium and thorium at the 10 part-per-trillion level. The basis of both sensor types is a specially designed polymer having selective binding sites for actinyl ions of the form MO{sub 2}{sup 2+}(aq), where M is any actinide in the +6 oxidation state. This binding site also traps ions of the form MO{sub 2}{sup +}(aq), where M is any actinide in the +4 oxidation state. In this way, the polymer is responsive to the two most common water-soluble ions of the actinide series. The chelating ring responsible for binding the actinyl ions was identified from the literature, calix[n]arene where n = 6. Several versions of this sensing polymer were coated on conductive substrates and demonstrated for actinide sensing. An optimized sensor was developed and is fully described in this report. It has a polymer bilayer, fabricated under the particular conditions given below. Two different operating modes were demonstrated having different capabilities. One is the chemFET mode (a FET is a field effect transistor) and the other is the voltammetric mode. These two sensors give complementary information regarding the actinide species in a sample. Therefore our recommendation is that both be used together in a probe. A detailed design for such a probe has been filed as a patent application with the United States Patent Office, and is patent pending. The sensing polymer incorporating this actinyl-chelating ring was tested under a variety of conditions and the operating limits were determined. A full factorial experiment testing the polymerization method was conducted to optimize performance and characteristics of this polymer. The actinyl-sensing polymer was also deposited on the gate of a field effect transistor (FET) and demonstrated as a sensitive detector for uranium. Millimeter scale electrodes, operated by a hand-held instrument assembled in this lab and operated in the voltammetric mode, were transported to the DOE-Nevada test site (Las Vegas, NV) where field detection and quantitation of plutonium, uranium, and a mixture of these two elements was also demonstrated. Several probe designs were prepared, built and tested including probes with movable protective windows. A miniature, battery powered potentiostat was designed, built and demonstrated for use in a hand-held field portable instrument. This work was performed largely by undergraduates who gained valuable research experience, and many of them have continued on to graduate schools. In addition, they all gained exposure to and appreciation for national security research, in particular non-proliferation research. Four graduate students participated and one earned the MS degree on this project.

Direction-Sensitive Hand-Held Gamma-Ray Spectrometer  

SciTech Connect

A novel, light-weight, hand-held gamma-ray detector with directional sensitivity is being designed. The detector uses a set of multiple rings around two cylindrical surfaces, which provides precise location of two interaction points on two concentric cylindrical planes, wherefrom the source location can be traced back by back projection and/or Compton imaging technique. The detectors are 2.0 × 2.0 mm europium-doped strontium iodide (SrI2:Eu2+) crystals, whose light output has been measured to exceed 120,000 photons/MeV, making it one of the brightest scintillators in existence. The crystal’s energy resolution, less than 3% at 662 keV, is also excellent, and the response is highly linear over a wide range of gamma-ray energies. The emission of SrI2:Eu2+ is well matched to both photo-multiplier tubes and blue-enhanced silicon photodiodes. The solid-state photomultipliers used in this design (each 2.0 × 2.0 mm) are arrays of active pixel sensors (avalanche photodiodes driven beyond their breakdown voltage in reverse bias); each pixel acts as a binary photon detector, and their summed output is an analog representation of the total photon energy, while the individual pixel accurately defines the point of interaction. A simple back-projection algorithm involving cone-surface mapping is being modeled. The back projection for an event cone is a conical surface defining the possible location of the source. The cone axis is the straight line passing through the first and second interaction points.

The overnight thermal environment of infants.  

PubMed

Thirty healthy infants between nine and 19 weeks each had skin and room temperature monitored continuously for a single night. A simultaneous assessment of the insulating quality of the infants bedding was made. The maximum infant skin temperature noted was 37.4 degrees C, the room temperatures ranged from 10.9 degrees C to 26.2 degrees C over all study infants. The insulation score ranged from 17 to 68, with the mean 33 (SD, 13). There was a highly significant correlation between insulation score and maximum infant temperature. A significant inverse correlation between insulation score and outside temperature was noted, but not between insulation score and room temperature. These findings indicate that some infants are inappropriately overdressed for their environmental temperature. PMID:2304686

Overnight lexical consolidation revealed by speech segmentation.  

PubMed

Two experiments explored the consolidation of spoken words, and assessed whether post-sleep novel competitor effects truly reflect engagement of these novel words in competition for lexical segmentation. Two types of competitor relationships were contrasted: the onset-aligned case (such as "frenzylk"), where the novel word is a close variant of the existing word: they start at the same time point and overlap on most of their segments; and the fully embedding case (such as "lirmucktoze"), where the existing word corresponds to a smaller embedded portion of its novel competitor and is thus less noticeable. Experiment 1 (pause detection) revealed a similar performance for both cases, with no competitor effect immediately after exposure, but significant inhibition after 24 h and seven days. Experiment 2 (word spotting) produced exactly the same pattern; however, as is the case with existing word carriers (cf. McQueen, Norris, & Cutler, 1994), the inhibition was much stronger for fully embedded than for onset-aligned targets (e.g., "lirmuckt" vs. "frenzyl"). Meanwhile, explicit measures of learning, i.e., free recall and recognition, improved over time. These results cannot be explained by either consolidation of episodic traces or acquisition of new phonological/dialectal variants. We argue instead that they reflect a general trait of vocabulary learning and consolidation. PMID:22261419

Herein a new compact (6 × 7 × 12 cm3), cost-effective, and wide-field NIR scanner has been developed towards contact as well as no-contact based real-time imaging in both reflectance and transmission mode. The scanner mainly consists of an NIR source light (between 700- 900 nm), an NIR sensitive CCD camera, and a custom-developed image acquisition and processing software to image an area of 12 cm2. Phantom experiments have been conducted to estimate the feasibility of diffuse optical imaging by using Indian-Ink as absorption-based contrast agents. As a result, the developed NIR system measured the light intensity change in absorption-contrasted target up to 4 cm depth under transillumination mode. Preliminary in-vivo studies demonstrated the feasibility of real-time monitoring of blood flow changes. Currently, extensive in-vivo studies are carried out using the ultra-portable NIR scanner in order to assess the potential of the imager towards breast imaging..

Hand-held based near-infrared optical imaging devices: a review.  

PubMed

Near-infrared (NIR) optical imaging is a non-invasive and non-ionizing modality that is emerging as a diagnostic/prognostic tool for breast cancer and other applications related to functional brain mapping. In recent years, hand-held based optical imaging devices are developed for clinical translation of the technology, as opposed to the various bulky optical imagers available. Herein, we review the different hand-held based NIR devices developed to date, in terms of the measurement techniques implemented (continuous wave, time or frequency-domain), the imaging methods used, and the specific applications towards which they were applied. The advantages and disadvantages of the different hand-held optical devices are described and also compared with respect to a novel hand-held based device currently developed in our Optical Imaging Laboratory towards three-dimensional tomography studies.

Relationship between blood lead and blood pressure in the NHANES II survey  

SciTech Connect

A large body of experimental data has shown that lead raises blood pressure and increases responsiveness to alpha-adrenergic agonists in rats and pigeons. These studies suggest the need to look for a similar relationship in humans. This paper examines the robustness of the previously reported association between blood lead and blood pressure in adult males. The association remains strong and is essentially unchanged in tests that include nutritional factors and demographic factors, alone or together, or in tests that include insignificant terms. The relationship was not confounded by age; it held for all adult men in the 20-45 age group, the 40-59 age group, and the 46-74 age group. Interaction terms for 25 30-year age groups (20-49, 21-50,. . . , 45-74) were all insignificant, indicating no difference in the relationship by age. The relationship is also robust to the inclusion of a time trend to account possible omitted time-varying factors, and it held in a model that controlled for possible site effects. Given the strong experimental evidence, the relationship is likely causal.

First, we observed that only a low proportion of mDCs was infected by T. cruzi after overnight culture of whole blood samples and trypomastigotes, as compared with monocytes and granulocytes. Cord blood mDCs were also less infected than their adult counterpart. Second, expression levels of HLA-DR and co-stimulatory molecules CD80, CD83 and CD86 were similar on infected and uninfected mDCs. Parasite lysate also triggered mDCs phenotypic maturation of both cord and adult blood cells, though in a lower extent than live parasites. These results strongly support a central role for extracellular trypomastigotes in activation of mDCs when parasites are incubated with whole blood cells. However, viability of trypomastigotes was not absolutely required for mDC activation. PMID:22327272

The association between blood pressure and whole blood methylmercury in a cross-sectional study among Inuit in Greenland  

PubMed Central

Background The Inuit in Greenland have a high average consumption of marine species and are highly exposed to methylmercury, which in other studies has been related to hypertension. Data on the relation between methylmercury and hypertension is limited, especially in populations subjected to a high exposure of methylmercury. We examined the relation between whole blood mercury and blood pressure (BP) in Inuit in Greenland. Methods A cross-sectional population-based study among adult Inuit in Greenland was performed in 2005–2009. Information on socio-demography, lifestyle, BP, blood samples and clinical measurements was obtained – the latter after overnight fasting. BP was measured according to standardized guidelines. Whole blood mercury concentration was used as a marker of exposure. The analyses were restricted to Inuit aged 30–69?years with four Greenlandic grandparents (N?=?1,861). Multivariate regression analyses with inclusion of confounders were done separately for men and women with the omission of participants receiving anti-hypertensive drugs, except for logistic regression analyses of the relation between mercury and presence of hypertension (yes/no). Results The mean whole blood mercury level was 20.5??g/L among men and 14.7??g/L among women. In multivariate analyses adjusted for confounders, diastolic BP decreased with increasing mercury concentration. In men diastolic BP decreased significantly for each four-fold increase in mercury concentration (Beta?=??0.04, standard error?=?0.01, p?=?0.001), while no relation between mercury and diastolic BP was found among women. For systolic BP, a similar non-statistically significant result was seen only for men (Beta?=??0.02, standard error?=?0.01, p?=?0.06). A relation between mercury and hypertension was only found in men; the odds ratio for hypertension was 0.99 (95% CI: 0.98-0.99). No relation between quintiles of mercury and hypertension was found. The relationship between mercury and BP parameters may be non-linear: In analyses of quintiles of mercury the overall effect of mercury on BP parameters was only statistically significant for diastolic BP among men (Wald test, p?=?0.01), however pairwise comparisons showed that some quintiles were not statistically different. This result is supported by LOESS modelling. Conclusions No adverse associations between whole blood mercury and blood pressure were found. With increasing whole blood mercury concentrations, diastolic BP and the risk of hypertension decreased among men in the study: this may be explained by confounding by exercise or unknown factors.

Breast cancer imaging and tomography using a hand-held optical imager  

NASA Astrophysics Data System (ADS)

Hand-held optical imaging devices are currently developed by several research groups as a noninvasive and non-ionizing method towards clinical imaging of breast cancer. The devices developed to date are typically utilized towards spectroscopic imaging via reflectance-based measurements. Additionally, a couple of devices have been used to perform 3D tomography with the addition of a second modality (e.g. ultrasound). A hand-held optical device that is unique in its ability to perform rapid 2D imaging and 3D tomography (without the use of a second modality) has been developed in our Optical Imaging laboratory. Herein, diffuse optical imaging studies are performed in breast cancer subjects. For these studies, the subject lay in a recliner chair and both breast tissues were imaged with the hand-held optical device which uses 785 nm laser source and an intensified CCD camera-based detector. Preliminary results demonstrate the ability to image invasive ductal carcinoma and lymphatic spread, as compared to the patient's medical records (e.g. xray, ultrasound, MRI). Multiple imaging studies with a subject undergoing chemotherapy demonstrated the potential to monitor response to treatment. Currently, studies are carried out to tomographically determine the 3D location of the tumor(s) in breast cancer subjects using the hand-held optical device.

Use of hand-held echocardiography to facilitate the management of cardiac disease in older people.  

PubMed

Access to echocardiography remains suboptimal for many older patients; hand-held echocardiography may improve access to this investigation. New methods of service provision may, however, not always result in appropriate use by clinicians. The aim of this study was to test whether the provision of hand-held echocardiography in a geriatric medicine service results in appropriate requests and changes in patient management. The methodology involved in this, was a prospective study of 100 patients referred for hand-held echocardiography in a geriatric medicine service. Information on reason for request, time from request to study, medical history, echocardiography history and medication were collected. Clinicians were asked how results had changed management 7-14 days after the investigation. The mean age of participating patients was 82.6 years. Echo requests were deemed appropriate in 93% of cases. Median time from request to echo was three days for inpatients and 14 days for outpatients. Fifty percent (50/100) of echos led to a change in cardiovascular management; a total of 75 separate changes in cardiovascular management resulted. Seventy-six percent of changes were deemed appropriate; 10% inappropriate and insufficient information was present for 14% of decisions. Provision of hand-held echocardiography allowed rapid investigation of patients for selected abnormalities. Requests were appropriate and appropriate changes to patient management occurred in most patients. PMID:21515528

Clinical translation of a hand-held optical imager for breast cancer diagnostics: In vitro and in vivo tomography studies  

Microsoft Academic Search

Optical imaging is an emerging technology towards non-invasive breast cancer diagnostics. In recent years, portable and patient comfortable hand-held optical imagers are developed towards two-dimensional (2D) tumor detections. However, these imagers are not capable of three-dimensional (3D) tomography because they cannot register the positional information of the hand-held probe onto the imaged tissue.

Transport across the Blood-Brain Barrier of Pluronic Leptin  

PubMed Central

Leptin is a peptide hormone produced primarily by adipose tissue that acts as a major regulator of food intake and energy homeostasis. Impaired transport of leptin across the blood-brain barrier (BBB) contributes to leptin resistance, which is a cause of obesity. Leptin as a candidate for the treatment of this obesity is limited because of the short half-life in circulation and the decreased BBB transport that arises in obesity. Chemical modification of polypeptides with amphiphilic poly(ethylene oxide)-poly(propylene oxide) block copolymers (Pluronic) is a promising technology to improve efficiency of delivery of polypeptides to the brain. In the present study, we determined the effects of Pluronic P85 (P85) with intermediate hydrophilic-lipophilic balance conjugated with leptin via a degradable SS bond [leptin(ss)-P85] on food intake, clearance, stability, and BBB uptake. The leptin(ss)-P85 exhibited biological activity when injected intracerebroventricularly after overnight food deprivation and 125I-leptin(ss)-P85 was stable in blood, with a half-time clearance of 32.3 min (versus 5.46 min for leptin). 125I-Leptin(ss)-P85 crossed the BBB [blood-to-brain unidirectional influx rate (Ki) = 0.272 ± 0.037 ?l/g · min] by a nonsaturable mechanism unrelated to the leptin transporter. Capillary depletion showed that most of the 125I-leptin(ss)-P85 taken up by the brain reached the brain parenchyma. Food intake was reduced when 3 mg of leptin(ss)-P85 was administered via tail vein in normal body weight mice [0–30 min, p < 0.0005; 0–2 h, p < 0.001]. These studies show that the structure based Pluronic modification of leptin increased metabolic stability, reduced food intake, and allowed BBB penetration by a mechanism-independent BBB leptin transporter.

Effect of different kinds of fibre on postprandial blood glucose in insulin-dependent diabetics.  

PubMed

Dietary fibre may retard glucose absorption in normal and diabetic subjects. It is, however, unclear which type of fibre would be most suitable for this purpose. We therefore studied whether pectin differs from fibre from barley (85%) and citrus (15%) (Dumovital) in its effect on postprandial blood glucose responses. Eight insulin-dependent diabetics fasted overnight and were then given a meal without their morning insulin. The basic meal, composed of 90 g white bread and 120 g jam (total carbohydrate 105 g), was given three times: alone, with 15 g pectin and with 15 g Dumovital fibre. Blood glucose was measured for three hours. The tests showed that pectin administration considerably inhibited the postprandial rise in blood glucose, while Dumovital showed no such effect. Barley/citrus fibre (a mixture of cellulose, hemicellulose, lignin and pectin) has not the same inhibiting effect on postprandial rise in blood glucose as pure pectin in insulin-dependent diabetics. Thus, the specific type of fibre must be considered when prescribing dietary fibre to diabetics. PMID:6257055

Substrate Utilization by the Failing Human Heart by Direct Quantification Using Arterio-Venous Blood Sampling  

PubMed Central

Metabolic substrate utilization of the human failing heart is an area of controversy. The purpose of this study is to directly quantify myocardial substrate utilization in moderately severe heart failure, type 2 diabetes and healthy controls using simultaneous coronary sinus and arterial blood sampling. Patients with heart failure (n?=?9, mean NYHA 2.7±0.5), with type 2 diabetes (n?=?5) and with normal heart function (n?=?10) were studied after an overnight fast in connection with electrophysiological investigations/treatments. A systemic infusion of [2H2]palmitate allowed for the calculation of absolute palmitate extraction across the heart. Blood samples were analysed for non-esterified fatty acids, triacylglycerol, glycerol, glucose, pyruvate, lactate, 3-hydroxybutyrate, and blood gases after simultaneous sampling of arterial and coronary sinus blood. Arterio-coronary sinus metabolite concentration differences and fractional extractions for all substrates were similar between the groups. The absolute NEFA uptakes assessed by [2H2]palmitate extraction were also similar between the groups. Using direct measurements of metabolic substrate uptake by arterio-venous difference technique, the compensated human failing heart does not appear to have reduced myocardial fatty acid uptake.

[Autologous blood transfusion].  

PubMed

Autologous blood transfusion techniques are the principal means of reducing allogeneic blood exposure. Those techniques were developed in order to prevent the risk of contamination by viruses, mainly HVB, HCV and HIV. However that risk has become so small that all studies show an exorbitant cost/efficiency ratio. Autologous blood transfusion would therefore be of no interest in terms of public health but a recent experimental study suggested a possible transmission of the BSE agent through blood. Until the matter is settled, the precaution principle means we should prefer alternative techniques to allogeneic blood whenever possible, hence a renewed interest in autologous transfusion.

Optimal use of blood in trauma patients  

PubMed Central

Injury is rapidly becoming the leading cause of death worldwide, and uncontrolled hemorrhage is the leading cause of potentially preventable death. In addition to crystalloid and/or colloid based resuscitation, severely injured trauma patients are routinely transfused RBCs, plasma, platelets, and in some centers either cryoprecipitate or fibrinogen concentrates or whole blood. Optimal timing and quantity of these products in the treatment of hypothermic, coagulopathic and acidotic trauma patients is unclear. The immediate availability of these components is important, as most hemorrhagic deaths occur within the first 3–6 h of patient arrival. While there are strongly held opinions and longstanding traditions in their use, there are little data within which to logically guide resuscitation therapy. Many current recommendations are based on euvolemic elective surgery patients and incorporate laboratory data parameters not widely available in the first few minutes after patient arrival. Finally, blood components themselves have evolved over the last 30 years, with great attention paid to product safety and inventory management, yet there are surprisingly limited clinical outcome data describing the long term effects of these changes, or how the components have improved clinical outcomes compared to whole blood therapy. When focused on survival of the rapidly bleeding trauma patient, it is unclear if current component therapy is equivalent to whole blood transfusion. In fact data from the current war in Iraq and Afghanistan suggest otherwise. All of these factors have contributed to the current situation, whereby blood component therapy is highly variable and not driven by long term patient outcomes. This review will address the issues raised above and describe recent trauma patient outcome data utilizing predetermined plasma:platelet:RBC transfusion ratios and an ongoing prospective observational trauma transfusion study.

Blood and tissue spatter associated with chainsaw dismemberment.  

PubMed

In response to the unexpected paucity of blood/tissue spatter at the site where a body of an adult woman was dismembered by an electric chainsaw, we dismembered two large pig carcasses with a small electric chainsaw in a controlled environment. These experiments demonstrated first that a large carcass could be easily dismembered by a small electric chainsaw. When the chainsaw bar is held parallel to the ground the majority of the blood and tissue is deposited directly beneath the saw and bar and very little elsewhere. If the discharge chute of the saw however is not oriented directly at the ground, larger amounts of blood and tissue may be sprayed on lateral surfaces or deposited some distance from the chainsaw. The characteristic striations created on the surface of wood as it is cut by a chainsaw can also be found on bony surfaces cut by a chainsaw. PMID:19737342

A simple medium enables bovine embryos to be held for seven days at 4?C  

PubMed Central

Cryopreservation methods using liquid nitrogen (LN2) for gametes and embryos are prevalent in mammalian artificial reproduction. However, the pregnancy rate from frozen embryos has not improved over the past two decades because freeze–thawing causes significant damage. The strict regulation of transportation of LN2 containers by airlines also limits exchange between breeders. In this article, we introduce a medium that enabled bovine embryos to be held for up to 7 days at 4°C. A pregnancy rate of 75% (24/32) was obtained for embryos held for 7 days in this medium and transferred to primed recipients. Its constituents were medium 199, foetal bovine serum, and HEPES for buffering. This technique will enable LN2-free storage and air transportation of embryos provided transplantation to recipients can be completed within 7 days.

Hand-held cow horn: resurgence of an old arm or a potential terrorist weapon.  

PubMed

A 23 year old man presented with intestinal evisceration from stab injury to the left side of the abdomen with a hand-held cow horn at a local night party. He complained of severe abdominal pain and bleeding at the site of injury. He was hemodynamically stable. At emergency exploration, the eviscerated bowel was viable with no adjacent mesenteric tear. Other intra abdominal organs were normal. The eviscerated bowel was lavaged and reduced into the abdomen through the 7 cm anterior abdominal wall laceration. The laceration was repaired and abdomen closed in layers. Post operative recovery was uneventful. The hand-held cow horn can easily be concealed and may pass through security checks undetected. It should be added to the ever increasing list of weapons of small scale terror. PMID:21502787

Views About Learning Physics Held by Physics Teachers with Differing Approaches to Teaching Physics  

NASA Astrophysics Data System (ADS)

Research into teacher thinking offers potential insights into ways of promoting better teaching. A recent qualitative study explored the views about physics, and learning and teaching physics of a group of teachers whose classroom practice was `traditional' and a group who used conceptual change teaching approaches. This paper focuses on the views about learning physics held by the two groups. To summarize and compare the groups, a composite description was created for each group. This composite description represents all the common views of teachers who were in that group. The composite description is termed `typical' teacher. The study concluded that the conceptual change teachers' views about learning physics were constructivist while the traditional teachers held absorptionist views.

Use of a hand-held Doppler to avoid abdominal wall vessels in laparoscopic surgery.  

PubMed Central

Laparoscopy in general surgery is becoming a wide-spread technique. Substantial anterior abdominal wall haemorrhage is a recognised complication of the laparoscopic technique. Ten patients were examined with an 8 MHz hand-held Doppler and the anterior abdominal wall vessels were marked on the skin. Colour flow duplex was used to confirm the presence of vessels found in this way. All 40 epigastric arteries were marked accurately and confirmed; 75 other intramural arteries were identified, although the majority were too small for duplex confirmation. The preoperative use of hand-held Doppler is a quick and non-invasive way to identify the epigastric and larger intramural arteries. Routine use of this technique to mark abdominal wall vessels in the areas of trocar insertion should reduce this complication of laparoscopic surgery.

Clearance monitoring using hand-held devices: operational implementation and challenges.  

PubMed

Clearance monitoring includes all measures taken and measurements performed to ensure that all pertinent regulatory conditions are met for clearance of waste material. For bulk material, only a limited number of monitoring techniques are feasible for providing the necessary proof of compliance in the time frames and at costs commensurate with operator and regulator expectations for decommissioning projects. Operationally, measurements using hand-held devices, such as contamination monitors using scintillator or proportional counter technology, might provide sufficiently short response times at acceptable accuracies to segregate the waste streams according to their level of contamination and allowing for a decision on their further processing. Recognizing the various limitations hand-held devices might display in bulk material screening during clearance monitoring measurements, the detection limits with respect to material self-attenuation and non-homogenous activity distributions have been investigated.

Evidence for ``held-back'' valence quarks from particle ratios in pp and pp collisions  

NASA Astrophysics Data System (ADS)

We show that recently measured particle ratios in the central region of pp and pp collisions give valuable information on the fate of valence quarks in a soft hadronic collision, indicating that a valence quark from each initial hadron is ``held back'' with a small momentum fraction. This mechanism is a key feature of the dual parton fragmentation approach to low-pT multiparticle production.

Noise reduction techniques in the design of a pneumatic-driven hand held power tool  

NASA Astrophysics Data System (ADS)

Pneumatic-driven hand-held power tools generate noise in the workplace. Current legislation in Europe and the USA aims at protecting workers against noise exposure. In the United States, the Occupational Safety and Health Administration (OSHA) requires that employers create a hearing conservation program if the noise exposure exceeds 85 dB(A). In the European Community under the Directive 2003/10/EC, employers are required to provide hearing protection if the noise exposure within the working environment exceeds 80 dB(A) and must require hearing protection to be worn if the noise exposure exceeds 85 dB(A). This paper examines the sources of noise which contribute to the overall noise from a hand-held power tool. A test plan was developed to identify these individual sources of noise and to determine if structure-borne noise or airborne noise is the dominant source relative to the overall noise level. The measurements were performed per International Standards Organization (ISO) 15744. This paper will describe the methodology used to identify the noise sources and reduce the overall noise of a hand-held power tool.

A hand-held electronic tongue based on fluorometry for taste assessment of tea.  

PubMed

A hand-held electronic tongue was developed for determining taste levels of astringency and umami in tea infusions. The sensing principles are based on quenching the fluorescence of 3-aminophthalate by tannin, and the fluorogenic reaction of o-phthalaldehyde (OPA) with amino acids to determine astringency and umami levels, respectively. Both reactions were measured by a single fluorescence sensing system with same excitation and emission wavelengths (340/425 nm). This work describes in detail the design, fabrication, and performance evaluation of a hand-held fluorometer with an ultra-violet light emitted diode (UVLED) and a photo-detector with a filter built-in. The dimension and the weight of proposed electronic tongue prototype are only 120×60×65 mm(3) and 150 g, respectively. The detection limits of this prototype for theanine and tannic acid were 0.2 ?g/ml and 1 ?g/ml, respectively. Correlation coefficients of this prototype compared with a commercial fluorescence instrument are both higher than 0.995 in determinations of tannin acid and theanine. Linear detection ranges of the hand-held fluorometer for tannic acid and theanine are 1-20 ?g/ml and 0.2-10 ?g/ml (CV<5%, n=3), respectively. A specified taste indicator for tea, defined as ratio of umami to astringency, was adopted here to effectively distinguish flavour quality of partially fermented Oolong teas. PMID:20728331

Gen-2 hand-held optical imager towards cancer imaging: reflectance and transillumination phantom studies.  

PubMed

Hand-held near-infrared (NIR) optical imagers are developed by various researchers towards non-invasive clinical breast imaging. Unlike these existing imagers that can perform only reflectance imaging, a generation-2 (Gen-2) hand-held optical imager has been recently developed to perform both reflectance and transillumination imaging. The unique forked design of the hand-held probe head(s) allows for reflectance imaging (as in ultrasound) and transillumination or compressed imaging (as in X-ray mammography). Phantom studies were performed to demonstrate two-dimensional (2D) target detection via reflectance and transillumination imaging at various target depths (1-5 cm deep) and using simultaneous multiple point illumination approach. It was observed that 0.45 cc targets were detected up to 5 cm deep during transillumination, but limited to 2.5 cm deep during reflectance imaging. Additionally, implementing appropriate data post-processing techniques along with a polynomial fitting approach, to plot 2D surface contours of the detected signal, yields distinct target detectability and localization. The ability of the gen-2 imager to perform both reflectance and transillumination imaging allows its direct comparison to ultrasound and X-ray mammography results, respectively, in future clinical breast imaging studies.

Hand-held optical imager (Gen-2): improved instrumentation and target detectability.  

PubMed

Hand-held optical imagers are developed by various researchers towards reflectance-based spectroscopic imaging of breast cancer. Recently, a Gen-1 handheld optical imager was developed with capabilities to perform two-dimensional (2-D) spectroscopic as well as three-dimensional (3-D) tomographic imaging studies. However, the imager was bulky with poor surface contact (~30%) along curved tissues, and limited sensitivity to detect targets consistently. Herein, a Gen-2 hand-held optical imager that overcame the above limitations of the Gen-1 imager has been developed and the instrumentation described. The Gen-2 hand-held imager is less bulky, portable, and has improved surface contact (~86%) on curved tissues. Additionally, the forked probe head design is capable of simultaneous bilateral reflectance imaging of both breast tissues, and also transillumination imaging of a single breast tissue. Experimental studies were performed on tissue phantoms to demonstrate the improved sensitivity in detecting targets using the Gen-2 imager. The improved instrumentation of the Gen-2 imager allowed detection of targets independent of their location with respect to the illumination points, unlike in Gen-1 imager. The developed imager has potential for future clinical breast imaging with enhanced sensitivity, via both reflectance and transillumination imaging. PMID:23224163

Evidence is presented to show that there is no hemolytic toxin producing the anemia in pernicious anemia. Partial evidence is presented to show that the periods of active blood destruction which are seen as the exception in pernicious anemia cases during a series of transfusions are due to the activity of the blood-destroying organs of the body rather than to the intrinsic weakness of the pernicious anemia blood corpuscle. It is questionable whether blood destruction is as important a factor in producing the anemia of pernicious anemia as it is at present usually assumed to be.

Drying drops of blood  

NASA Astrophysics Data System (ADS)

The drying of a drop of human blood is fascinating by the complexity of the physical mechanisms that occur as well as the beauty of the phenomenon which has never been previously evidenced in the literature. The final stage of full blood evaporation reveals for a healthy person the same regular pattern with a good reproducibility. Other tests on anemia and hyperlipidemic persons were performed and presented different patterns. By means of digital camera, the influence of the motion of red blood cells (RBCs) which represent about 50% of the blood volume, is revealed as well as its consequences on the final stages of drying. The mechanisms which lead to the final pattern of dried blood drops are presented and explained on the basis of fluid and solid mechanics in conjunction with the principles of hematology. Our group is the first to evidence that the specific regular patterns characteristic of a healthy individual do not appear in a dried drop of blood from a person with blood disease. Blood is a complex colloidal suspension for which the flow motion is clearly non-Newtonian. When drops of blood evaporate, all the colloids are carried by the flow motion inside the drop and interact.

Is there a link between hyperuricemia, morning blood pressure surge, and non-dipping blood pressure pattern in metabolic syndrome patients?  

PubMed Central

Background: Hypertensive patients usually have a blunted nocturnal decrease, or even increase, in blood pressure during sleep. There is also a tendency for increased occurrence of cardiovascular events between 6 and 12 am due to increased morning blood pressure surge (MBPS). Co-occurrence of metabolic syndrome (MetS) and hypertension is also a common problem. Hyperuricemia might trigger the development of hypertension, chronic renal failure, and insulin resistance. In this study, we aimed to determine whether there is a relationship between hyperuricemia, MetS, nocturnal blood pressure changes, and MBPS. Method: A total of 81 newly diagnosed hypertensive MetS patients were included in this study. Ambulatory blood pressure monitoring of patients was done and patients’ height, weight, and waist and hip circumferences were recorded. Fasting blood glucose (FBG), lipid profile, creatinine, potassium, uric acid, hematocrit levels were studied. Results: Non-dipper (ie, those whose blood pressure did not drop overnight) patients had higher waist–hip ratios (WHR) (P = 0.003), uric acid (P = 0.0001), FBG (P = 0.001), total and low-density lipoprotein cholesterol levels (P = 0.0001). Risk analysis revealed that hyperuricemia was a risk factor for non-dipping pattern (P < 0.0001, odds ratio = 8.1, 95% confidence interval = 1.9–33.7). Patients in the highest quadrant for uric acid levels had higher FBG (P = 0.001), low-density lipoprotein cholesterol (P = 0.017), WHR (P = 0.01), MBPS (P = 0.003), and night diastolic blood pressure compared with lowest quadrant patients (P = 0.013). Uric acid levels were also positively correlated with night ambulatory blood pressure (ABP) (r = 0.268, P =0.05), night diastolic blood pressure (r =0.3, P =0.05), and MBPS (r =0.3, P =0.05). Conclusion: Evaluation of hypertensive patients should also include an assessment of uric acid level and anthropometric measurements such as abdominal obesity. Hyperuricemia seems to be closely related to undesired blood pressure patterns and this may signal to the clinician that an appropriate therapeutic approach is required.

Blood rheology and aging  

PubMed Central

The flow properties of blood play significant roles in tissue perfusion by contributing to hydrodynamic resistance in blood vessels. These properties are influenced by pathophysiological processes, thereby increasing the clinical relevance of blood rheology information. There is well-established clinical evidence for impaired blood fluidity in humans of advanced age, including enhanced plasma and whole blood viscosity, impaired red blood cell (RBC) deformability and enhanced RBC aggregation. Increased plasma fibrinogen concentration is a common finding in many studies owing to the pro-inflammatory condition of aged individuals; this finding of increased fibrinogen concentration explains the higher plasma viscosity and RBC aggregation in elderly subjects. Enhanced oxidant stress in advanced age is also known to contribute to altered blood fluidity, with RBC deformability being an important determinant of blood viscosity. Several studies have shown that physical activity may improve the hemorheological picture in elderly subjects, yet well-designed observational and mechanistic studies are required to determine the specific effects of regular exercise on hemorheological parameters in healthy and older individuals.

Integrated Blood Barcode Chips  

PubMed Central

Blood comprises the largest version of the human proteome1. Changes of plasma protein profiles can reflect physiological or pathological conditions associated with many human diseases, making blood the most important fluid for clinical diagnostics2-4. Nevertheless, only a handful of plasma proteins are utilized in routine clinical tests. This is due to a host of reasons, including the intrinsic complexity of the plasma proteome1, the heterogeneity of human diseases and the fast kinetics associated with protein degradation in sampled blood5. Simple technologies that can sensitively sample large numbers of proteins over broad concentration ranges, from small amounts of blood, and within minutes of sample collection, would assist in solving these problems. Herein, we report on an integrated microfluidic system, called the Integrated Blood Barcode Chip (IBBC). It enables on-chip blood separation and the rapid measurement of a panel of plasma proteins from small quantities of blood samples including a fingerprick of whole blood. This platform holds potential for inexpensive, non-invasive, and informative clinical diagnoses, particularly, for point-of-care.

Designing blood oxygenators.  

PubMed

Extracorporeal blood oxygenators are used to provide cardiopulmonary support during open heart surgery. In the study reported here, mass transfer correlations were determined for commercially available blood oxygenators. Two configurations used commercially, flow outside and across bundles of hollow fibers and flow in thin channels between parallel flat sheet membranes, were investigated. Water and glycerol/water mixtures were used as a substitute for blood. Diffusion of oxygen into and out of these solutions was studied. For flow across bundles of hollow fibers, the mass transfer correlations derived here are in agreement with analogous correlations for crossflow heat exchangers. However, for flow in thin channels, the rate of mass transfer is often less than predicted from theory. This compromised mass transfer can be explained by considering slight variations in the thickness of the blood flow channels. The mass transfer correlations developed here could be used to design better blood oxygenators. PMID:12783841

Phase transitions of capillary-held liquids in a slit-like pore.  

PubMed

Dynamics of capillary held liquids plays important roles in a wide range of systems including adhesion, printing of paints and inks, the behavior of wet granular materials, and the mass transfer through porous media. Recent study suggested the presence of two distinct modes for the disappearance of capillary-held liquids in a slit-like pore of adjustable slit width that depended on the slit-opening rates. In contrast to the first mode that is well-documented in terms of the Young-Laplace equation, a novel and unexpected mode was observed when the liquid bridge was held in the vicinity of the thermodynamic phase boundary (equilibrium Kelvin length). Here we extended the study to three new compounds that have a wide range of vapor pressures. An evaporating liquid bridge developed large refractive index gradients that extended over a few micrometers from the edge of the meniscus once the slit width was increased beyond the equilibrium Kelvin length. This interfacial region with depleted refractive index retreated inward as the meniscus shrank with time, and the refractive index of the entire bridge subsequently fell from that of the liquid once the interfacial regions from the opposite sides of the shrinking bridge met at the center. The refractive index recovered to that of the liquid when the slit width was closed to below the Kelvin length and the vapor was allowed to recondense. The time scale of the evaporation and condensation depended on the size of the surface gap, and, when the surfaces were placed at a separation very close to the Kelvin length, it was possible to detect a stage in which the system was in an apparent kinetic equilibrium between two physical states--with and without the liquid connecting the two surfaces.

Phantom study of a new hand-held ?-imaging probe for radio-guided surgery.  

PubMed

In recent years, hand-held mini ?-cameras have been increasingly used to perform scintigraphic imaging during surgery. The aim of the present work was to evaluate the physical characteristics of a new high-sensitivity hand-held mini ?-camera through specific phantom measurements. To characterize the performances of the imaging probe Guardian2 hand-held ?-camera, we measured its sensitivity and depth transmission curve, the extrinsic spatial resolution and spatial linearity, the spatial uniformity, and the count-rate linearity. We also estimated its whole image quality through the contrast-to-noise ratio of four hot spheres (internal diameters ranging from 4.9 to 9.8 mm). The sensitivity of the imaging probe Guardian2 ?-camera was 204 counts/s/MBq; it had a high spatial resolution (2.5 mm FWHM at contact) and optimal linearity of counts (Pearson's coefficient, R=0.999). The integral uniformity was 12.0% in the useful field of view (FOV) and 8.8% in the central FOV, whereas the differential uniformity was 5.7% in the useful FOV and 4.0% in the central FOV. The system was able to detect and distinguish all four small spheres used for the whole quality test. The contrast-to-noise ratio was evaluated both at contact with the collimator and with a 5-cm-thick interposed Plexiglas slab. The ?-imaging probe that we evaluated demonstrated good performance, confidently allowing its use for specific clinical applications in radio-guided surgery. PMID:23103999

Workshop on cancer biometrics: identifying biomarkers and surrogates of cancer in patients: a meeting held at the Masur Auditorium, National Institutes of Health.  

PubMed

The current excitement about molecular targeted therapies has driven much of the recent dialog in cancer diagnosis and treatment. Particularly in the biologic therapy of cancer, identifiable antigenic T-cell targets restricted by MHC molecules and the related novel stress molecules such as MICA/B and Letal allow a degree of precision previously unknown in cancer therapy. We have previously held workshops on immunologic monitoring and angiogenesis monitoring. This workshop was designed to discuss the state of the art in identification of biomarkers and surrogates of tumor in patients with cancer, with particular emphasis on assays within the blood and tumor. We distinguish this from immunologic monitoring in the sense that it is primarily a measure of the tumor burden as opposed to the immune response to it. Recommendations for intensive investigation and targeted funding to enable such strategies were developed in seven areas: genomic analysis; detection of molecular markers in peripheral blood and lymph node by tumor capture and RT-PCR; serum, plasma, and tumor proteomics; immune polymorphisms; high content screening using flow and imaging cytometry; immunohistochemistry and tissue microarrays; and assessment of immune infiltrate and necrosis in tumors. Concrete recommendations for current application and enabling further development in cancer biometrics are summarized. This will allow a more informed, rapid, and accurate assessment of novel cancer therapies. PMID:15725954

Area estimation in pharmacokinetic studies using a hand-held programmable calculator.  

PubMed

A short program for area analysis in pharmacokinetic studies using the Hewlett-Packard HP41C hand-held programmable calculator is described. Area under the concentration-time curve is calculated firstly within defined time limits and then with extrapolation to infinite time using the slope constant of the terminal phase. Input of concentration-time data is simple and there is no limit on the number of time-concentration co-ordinates which can be entered for area calculation. PMID:6735513

Comprehensive approach to CT-guided procedures with a hand-held guidance device.  

PubMed

A technically successful biopsy or drainage procedure performed with computed tomographic (CT) guidance depends on two essential elements: determination of the correct entry point on the patient and placement of the biopsy needle or trocar drainage catheter along a predetermined track. A hand-held guidance device was used in conjunction with the lighting system on the CT scanner and measurements obtained from CT images to achieve this goal in 40 patients. The approach minimized trauma to the patient and decreased the time required for CT. PMID:2294561

Quantum manipulation of tunnelling for two bosons held in a driven triple-well  

NASA Astrophysics Data System (ADS)

Coherent control of quantum tunnelling is investigated analytically for two bosons held in a driven triple-well potential. In the high-frequency region within resonance, the non-Floquet states with slowly varying populations are constructed by the linear superposition of Floquet solutions. For the non-resonance case with appropriate reduced parameters, we obtain another set of analytical solutions and their numerical correspondences, which exhibits the selective tunnelling effect of atoms. Applying the presented analytical results, a scheme to transport two bosons from the first well to the third is suggested by adjusting the driving parameters.

Blood viscosity and circulatory shock  

Microsoft Academic Search

Rheological features of the whole blood and blood components are of potential importance for microcirculatory blood flow in circulatory shock. The relative contribution of vascular geometric and rheological factors to the resistance to blood flow in the various shock states in man, however, are hard to elucidate [73]. Blood viscosity is mainly determined by haematocrit. In low flow states RBC

Factors Influencing Blood Donation Behaviour  

Microsoft Academic Search

Worldwide there is a shortage of active blood donors, and the problem of attracting and retaining sufficient donors to meet demand for blood and blood products is a serious one. This study has identified variables that help explain the decision to donate blood. Thus, the findings offer blood collection agencies guidance with the task of formulating specific strategies to address

Red blood cell proteomics.  

PubMed

Since its discovery in the 17th century, the red blood cell, recognized in time as the critical cell component for survival, has been the focus of much attention. Its unique role in gas exchange (oxygen/CO(2) transport) and its distinct characteristics (absence of nucleus; biconcave cell shape) together with an - in essence - unlimited supply lead to extensive targeted biochemical, molecular and structural studies. A quick PubMed query with the word "erythrocyte" results in 198 013 scientific articles of which 162 are red blood cell proteomics studies, indicating that this new technique has been only recently applied to the red blood cell and related fields. Standard and comparative proteomics have been widely used to study different blood components. A growing body of proteomics literature has since developed, which deals with the characterization of red blood cells in health and disease. The possibility offered by proteomics to obtain a global snapshot of the whole red blood cell protein make-up, has provided unique insights to many fields including transfusion medicine, anaemia studies, intra-red blood cell parasite biology and translational research. While the contribution of proteomics is beyond doubt, a full red blood cell understanding will ultimately require, in addition to proteomics, lipidomics, glycomics, interactomics and study of post-translational modifications. In this review we will briefly discuss the methodology and limitations of proteomics, the contribution it made to the understanding of the erythrocyte and the advances in red blood cell-related fields brought about by comparative proteomics.

Orbital blood cyst.  

PubMed Central

A blood cyst of the orbit is an unusual cause of proptosis and most likely arises in a pre-existing haemangioma. If the cyst occurs at the apex of the orbit the blood should be aspirated. This is followed by excision of the cyst wall, the dissection being done with the aid of an operating microscope. If there is evidence of intracranial connection of the blood cyst, namely, splayed superior orbital fissure or cerebrospinal fluid leak, then the patient should be treated with an antibiotic to prevent intracranial infection.

Fate of codling moth (Lepidoptera: Tortricidae) in harvested apples held under short photoperiod.  

PubMed

Codling moth, Cydia pomonella L., is a cosmopolitan pest of pome and stone fruits. It has been identified as a quarantine pest of concern in a number of countries where it is not known to occur, most of them tropical or subtropical countries. Although considerable work has been done on the basic biology and physiology of this temperate pest, little is known on its potential to develop and establish in tropical environments with short photoperiods and few to no days below 10 degrees C. Apples were harvested over three field seasons (2007-2009) from unmanaged orchards in central Washington State and subjected to simulated commercial cold storage at 1.1 +/- 2 degrees C for up to 119 d. After cold storage, infested fruits were held at 20 degrees C under a 12:12 L:D photoperiod for up to 6 mo. Over the entire experiment only 27% of the larvae collected exited the fruit and cocooned. Of those 27%, only 1.06% of larvae held under a 12:12 L:D photoperiod successfully emerged as moths. No moths emerged when host fruit would be available in a representative importing country in the tropics over the 3 yr of testing. These results indicate that codling moth in apples from the Pacific Northwest pose little threat of surviving and establishing in tropical regions where daylength is insufficient to break diapause and the chilling requirement is not met.

Differential distribution of glycine receptor subtypes at the rat calyx of Held synapse  

PubMed Central

The properties of glycine receptors (GlyRs) depend upon their subunit composition. While the prevalent adult forms of GlyRs are heteromers, previous reports suggested functional ? homomeric receptors in mature nervous tissues. Here we show two functionally different GlyRs populations in the rat medial nucleus of trapezoid body (MNTB). Postsynaptic receptors formed ?1/? containing clusters on somatodendritic domains of MNTB principal neurons, co-localizing with glycinergic nerve endings to mediate fast, phasic inhibitory postsynaptic currents (IPSCs). By contrast, presynaptic receptors on glutamatergic calyx of Held terminals were composed of dispersed, homomeric ?1 receptors. Interestingly, the parent cell bodies of the calyces of Held, the globular bushy cells (GBCs) of the cochlear nucleus, expressed somatodendritic receptors (?1/? heteromers) and showed similar clustering and pharmacological profile as GlyRs on MNTB principal cells. These results suggest that specific targeting of glycine receptor ? subunit produces segregation of GlyR subtypes involved in two different mechanisms of modulation of synaptic strength.

Intraoperative radioimmunodetection of colorectal tumor with a hand-held radiation detector  

SciTech Connect

A hand-held gamma detection probe was used intraoperatively to localize primary and recurrent colorectal tumors in 28 patients 48 to 72 hours after they received an intravenous injection of 2.2 mCi of iodine-131 labeled anticarcinoembryonic antigen polyclonal baboon antibody. Preoperative evaluation included determination of serum carcinoembryonic antigen, barium enema, colonoscopy, chest film, computerized axial tomography, liver, spleen, and bone scans, and endoscopy when indicated. Preoperative whole-body imaging correctly localized primary tumors in only 33 percent of the patients, whereas it correctly demonstrated tumor in 64 percent of those with recurrent disease. Intraoperative tumor-to-background ratios derived from the detector probe were elevated in all patients, averaging 3.97:1 in primary lesions and 4.18:1 in recurrent tumors. Postoperatively, carcinoembryonic antigen was localized in tissues with the avidin-biotin peroxidase staining technique to confirm intraoperative readings. Variations in stain uptake in a patient could be correlated with variations in radiation detector readings in the same patient. Results support our previous work in nude mice, demonstrating the improved sensitivity and specificity of the hand-held gamma detection device over whole-body imaging for intraoperative localization of immunoradiolabeled tumors.

The development of the hand-held dual-sensor ALIS  

NASA Astrophysics Data System (ADS)

Since 2002, we have developed a new hand-held land mine detection dual-sensor ALIS. ALIS is equipped with a metal detector and a GPR, and it has a sensor tracking system, which can record the GPR and Metal detector signal with its location. It makes possible to process the data afterwards, including migration. The migration processing drastically increases the quality of the image of the buried objects. The new system, we do not need any standard mark on the ground. Also, ALIS uses two different GPOR systems, including VNA (Vector Network Analyzer) based GPR and an Impulse GPR. VNA based GPR can provide better quality GPR images, although the impulse GPR is faster and light weight. ALIS evaluation tests were held in mine affected courtiers including Afghanistan, Croatia, Egypt and Cambodia. In the two-month evaluation test in Cambodia, ALIS worked without any problem. After some demonstrations and evaluation, we got many useful suggestions. Using these advises, we have modified the ALIS and it is now more easy to use. ALIS will be commercialized in 2007.

Algorithms for a hand-held miniature x-ray fluorescence analytical instrument  

SciTech Connect

The purpose of this joint program was to provide technical assistance with the development of a Miniature X-ray Fluorescence (XRF) Analytical Instrument. This new XRF instrument is designed to overcome the weaknesses of spectrometers commercially available at the present time. Currently available XRF spectrometers (for a complete list see reference 1) convert spectral information to sample composition using the influence coefficients technique or the fundamental parameters method. They require either a standard sample with composition relatively close to the unknown or a detailed knowledge of the sample matrix. They also require a highly-trained operator and the results often depend on the capabilities of the operator. In addition, almost all existing field-portable, hand-held instruments use radioactive sources for excitation. Regulatory limits on such sources restrict them such that they can only provide relatively weak excitation. This limits all current hand-held XRF instruments to poor detection limits and/or long data collection times, in addition to the licensing requirements and disposal problems for radioactive sources. The new XRF instrument was developed jointly by Quantrad Sensor, Inc., the Naval Research Laboratory (NRL), and the Department of Energy (DOE). This report describes the analysis algorithms developed by NRL for the new instrument and the software which embodies them.

Development of a hand-held forensic-lidar for standoff detection of chemicals  

NASA Astrophysics Data System (ADS)

The design of a forensic-lidar is reported, enabling a single operator to perform the spectral identification of a labeled object at 5 m distance using a compact, hand-held instrument, low-power excitation (1 mW) and short sampling times (under 2 s) from a sample less than 100-?m thick. The system integrates a modified single-lens-reflex (SLR) telephoto camera with an optical-fiber coupled Raman probe head. Spectral analysis was achieved using an optical-fiber coupled spectrograph employing a volume-phase holographic grating, charge coupled device array detection and visible excitation. Thus, spectra may be acquired from objects encased in transparent packaging or behind glass windows. The use of a modified SLR camera enables accurate sample alignment using the visible spectrum and collection of surface-enhanced resonance Raman scattered flux through the SLR camera lens using epi-illumination. A single operator may acquire fingerprint recognition of a material using a single hand-held unit and spectrum-matching software. The instrument design is reported with preliminary performance such as spectrograph resolution and transmission. A preliminary spectrum is presented at a standoff distance of 5 m.

Stabilized, hand-held, gamma-ray verification instrument for special nuclear materials  

SciTech Connect

For many years, Los Alamos has developed intelligent, hand-held, search instruments for use by non-specialists to search for special nuclear materials (SNM). The instruments sense SNM by detecting its emitted radiation with scintillation detectors monitored by digital alarm circuitry. Now, we have developed a new hand-held instrument that can verify the presence or absence of particular radioisotopes by analyzing gamma-ray spectra. The new instrument is similar to recent, microprocessor-based, search instruments, but has LED detector stabilization, three adjustable regions-of-interest, and additional operating programs for spectrum analysis. We call the new instrument an SNM verification instrument. Its spectrum analysis capability can verify the presence or absence of specific plutonium isotopes in containers or verify the presence of uranium and its enrichment. The instrument retains the search capability, light weight, and low-power requirement of its predecessors. Its ready portability, detector stabilization, and simple operation allow individuals with little technical training to verify the contents of SNM containers. 5 refs., 5 figs.

Finger tracking for hand-held device interface using profile-matching stereo vision  

NASA Astrophysics Data System (ADS)

Hundreds of millions of people use hand-held devices frequently and control them by touching the screen with their fingers. If this method of operation is being used by people who are driving, the probability of deaths and accidents occurring substantially increases. With a non-contact control interface, people do not need to touch the screen. As a result, people will not need to pay as much attention to their phones and thus drive more safely than they would otherwise. This interface can be achieved with real-time stereovision. A novel Intensity Profile Shape-Matching Algorithm is able to obtain 3-D information from a pair of stereo images in real time. While this algorithm does have a trade-off between accuracy and processing speed, the result of this algorithm proves the accuracy is sufficient for the practical use of recognizing human poses and finger movement tracking. By choosing an interval of disparity, an object at a certain distance range can be segmented. In other words, we detect the object by its distance to the cameras. The advantage of this profile shape-matching algorithm is that detection of correspondences relies on the shape of profile and not on intensity values, which are subjected to lighting variations. Based on the resulting 3-D information, the movement of fingers in space from a specific distance can be determined. Finger location and movement can then be analyzed for non-contact control of hand-held devices.

Fast coregistered breast imaging in vivo using a hand-held optical imager  

NASA Astrophysics Data System (ADS)

A hand-held optical imaging device has been developed in our laboratory towards fast 2D imaging and 3D tomography for breast cancer diagnosis. The device has the unique abilities: (1) to contour to different tissue curvatures using a flexible probe face; (2) perform fast 2D imaging by employing simultaneous over sequential source illumination; and (3) self coregistration towards (future) 3D tomography. The objective of the current work is to demonstrate fast coregistered 2D imaging on breast tissue of healthy female subjects. Fluorescence imaging experiments are performed in vitro and in vivo to demonstrate coregistered imaging as well as the ability to detect deep targets from multiple surface scans. A 0.45 cc spherical target filled with 1 ?M indocyanine green is embedded at various depths of a cubical phantom filled with chicken breast (in vitro models). For in vivo studies, the fluorescent target is placed under the flap of the breast tissue to represent a tumor for fluorescence imaging. Multiple scans (fast continuous-wave images of fluorescence intensity) are collected and coregistered at different locations on the breast tissue. This study demonstrates the potential of the hand-held optical device towards future in vivo surface imaging and tomographic imaging for 3D tumor localization.

[Blood boosting today].  

PubMed

The last Winter Olympics and recent cycling events have once again called attention to the use by endurance sportsmen and women of a variety of approaches designed to increase the blood hemoglobin concentration and oxygen-carrying capacity. An increased hemoglobin concentration and maximal oxygen uptake can be achieved by training at high altitude or by "living high and training low". It can also be procured by "blood boosting" with erythropoietin or darbepoietin, blood infusion, or misuse of hemoglobin-based oxygen carriers. This paper describes methods of increasing oxygen transport, with the accent on blood infusion, which is again relevant today with the development of a test able to detect recombinant human erythropoietins.
