Based on the ecological and economic problems in Good Agriculture Practice (GAP) of Chinese material medica, we introduced the origin, concept, features and operative technology of eco-agriculture worldwide, emphasizing its modes on different biological levels of landscape, ecosystem, community, population, individual and gene in China. And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.

Introduction: A meta-analysis is a statistical and analytical method which combines and synthesizes different independent studies and integrates their results into one common result. Goal: Analysis of the journals “Medical Archives”, “Materia Socio Medica” and “Acta Informatica Medica”, which are located in the most eminent indexed databases of the biomedical milieu. Material and methods: The study has retrospective and descriptive character, and included the period of the calendar year 2014. Study included six editions of all three journals (total of 18 journals). Results: In this period was published a total of 291 articles (in the “Medical Archives” 110, “Materia Socio Medica” 97, and in “Acta Informatica Medica” 84). The largest number of articles was original articles. Small numbers have been published as professional, review articles and case reports. Clinical events were most common in the first two journals, while in the journal “Acta Informatica Medica” belonged to the field of medical informatics, as part of pre-clinical medical disciplines. Articles are usually required period of fifty to fifty nine days for review. Articles were received from four continents, mostly from Europe. The authors are most often from the territory of Bosnia and Herzegovina, then Iran, Kosovo and Macedonia. Conclusion: The number of articles published each year is increasing, with greater participation of authors from different continents and abroad. Clinical medical disciplines are the most common, with the broader spectrum of topics and with a growing number of original articles. Greater support of the wider scientific community is needed for further development of all three of the aforementioned journals. PMID:25870484

The Acta Astronautica Journal was firstly published in 1955 as the official Journal of the International Astronautical Federation (IAF) with the title Astronautica Acta. It is entering its 60th year in 2014. In 1962, the Astronautica Acta became the official Journal of the International Academy of Astronautics (IAA) established in 1960. A total of 18 volumes had been published from 1955 to 1973 under the leadership of three Editor-in-Chiefs: F. Hecht, Theodore von Karman, and Martin Summerfield. In 1974, A.K. Oppenheim became the new Editor-in-Chief and several evolved changes were performed including change of the title to Acta Astronautica (for grammatical correctness), cover page change, and format change. From 1974 to 2010, another three Editor-in-Chiefs led the journal with 67 volumes published. They were A.K. Oppenheim, Jean-Pierre Marec, and Rupert Gerzer. The current Editor-in-Chief Jeng-Shing Chern (Rock) took over the job from 2011. Total pages and articles published in 2012 are 3586 and 356, respectively. Currently, the Acta Astronautica Editorial Board consists of one Editor-in-Chief, 15 Co-Editors, one Managing Editor and one Honorary Editor-in-Chief (Jean-Pierre Marec). After 59 years, the Acta Astronautica has become a well-known journal worldwide. Its current rank and impact factor are 7/63 and 0.701, respectively. This paper presents some of the details as well as new strategies and steps. In particular, supports from the IAA Academicians are mandatory and most welcome.

Sakae Miki said Classified Emergency Materia Medica had been the dominant standard of herbology throughout Joseon Dynasty, and that Compendium of Materia Medica had only been accepted so lately that a few books used herbological result of it in the late Joseon Dynasty. But according to Visiting Old Beijing Diary written by Munjoong Seo in 1690, Compendium of Materia Medica was in fact introduced before the year 1712, the year Miki Sakae argued to be the year Compendium of Materia Medica was accepted to Joseon officially. Now, we can assume that the introducing year of Compendium of Materia Medica was faster than Miki Sakae's opinion by the following reasons; the effort of Joseon government and intellectuals to buy new books of Ming & Ching; the publishing year of the book for living in countryside regarded as the first citing literature of Compendium of Materia Medica. And the True Records of the Joseon Dynasty and many collections written by intellectuals in the 18th century show that the herbological knowledge from Compendium of Materia Medica had already spread to the corners of Joseon Dynasty. Thus we can make the following assumption: Classified Emergency Materia Medica and Compendium of Materia Medica had coexisted in the late Joseon Dynasty. Sakae Miki suggested 6 examples which used Compendium of Materia Medica in the late Joseon Dynasty. I reviewed two of them in this paper, Essentials of Materia Medica & Handbook of Prescriptions from Materia Medica. Essentials of Materia Medica quoted Compendium of Materia Medica briefly focusing clinical use, and Handbook of Prescriptions from Materia Medica also re-compiled Compendium of Materia Medica to practical use according to the form of Treasured Mirror of Eastern Medicine. It means that the results of Compendium of Materia Medica have been used positively, based on the herbology of materia medica from countryside. From this point of view, the hyphothesis there weren't any herbological progress after accepting

Acta Ophthalmologica appeared as the scientific journal of the Nordic ophthalmological Societies in 1923. The intention was to expose the clinical and experimental developments among the ophthalmological communities of the four Nordic countries: Denmark, Finland, Norway and Sweden. The collaboration within the field of ophthalmology had been attempted with the publication of 'Nordisk ophthalmologisk Tidsskrift' in the years 1889-1892. Now, once again, the wish for a tighter Nordic cooperation was explored by enthusiastic ophthalmologists in all four countries. One person stands out as the driving force, K.K.K. Lundsgaard, who in spite of his early death in 1931 was remembered by name on the front page of Acta since 1936 by the Latin phrase 'A K.K.K. Lundsgaard edi coepta'. The present review recalls details from the early years when the journal found its place in the ophthalmology and creates the background for some reflections on purpose and goals by publishing a scientific journal. © 2011 The Authors.

Supak-Smolcic, Vesna; Simundic, Ana-Maria

2015-01-01

Recent findings of authorship criteria violations in the manuscripts submitted to Biochemia Medica show that almost 40% of authors do not meet necessary criteria for authorship and thus indicate the need for better dissemination of editorial policy on authorship in our journal. We believe that such cases are mostly due to the authors' unawareness or the lack of understanding of the authorship criteria. With this article we therefore wish to declare our editorial policy on authorship and authorship criteria. Biochemia Medica endorses the authorship policy provided by the International Committee of Medical Journal Editors (ICMJE). Information on authorship is assessed by self-reported authorship claims during on-line manuscript submission. Those who meet ICMJE criteria shall be listed as authors, and all listed authors shall fulfill ICMJE criteria. All authors should be responsible for content of the article and have to know other authors' contributions to the study. Biochemia Medica will follow recommendations provided by Committee on Publication Ethics (COPE) flowcharts for possible disputes. By adhering to this procedure we hope to raise awareness about the importance of compliance with ICMJE authorship recommendations.

According to archaeological discoveries, humans began to make use of marine natural resources early in the Palaeolithic era. In the Spring and Autumn period and Warring States period, they began to use marine life as medicines and also had simple cognitions on their efficacy and processing. In the Qin and Han dynasties, people further deepened the understanding of the marine Chinese materia medica and created prescriptions making use of marine drugs. In the Tang and Song period, the number of marine Chinese materia medica species and corresponding prescriptions apparently increased. The cognitions of the property, flavor, efficacy as well as the compatible principle of marine Chinese materia medica was further deepened and the scope of their treatment also significantly expanded. In the Ming and Qing dynasties, the cognition of the marine Chinese materia medica was mainly the conclusions of the previous experience. After the founding of the People's Republic of China (PRC), with the development of science and technologies, the ability of exploiting and utilizing the marine Chinese materia medica by people dramatically increased, and the species of marine Chinese materia medica reached more than one thousand. However, the development of marine Chinese materia medica is confronted with new problems; although the number of species of marine Chinese materia medica increased, the understanding of their property and flavor is obviously lagging behind, which seriously affects the clinical application of marine Chinese materia medica.

The major objective in root canal treatment is to disinfect the entire root canal system. Cleaning, shaping, and use of antimicrobial medicaments are effective in reducing the bacterial load to some extent, but some bacteria do remain behind and multiply, causing reinfection. Taking into consideration the ineffectiveness, potential side-effects and safety concerns of synthetic drugs, the herbal alternatives for endodontic usage might prove to be advantageous. Over the past decade, interest in drugs derived from medicinal plants has markedly increased. Phytomedicine has been used in dentistry as anti-inflammatory, antibiotic, analgesic, sedative and also as endodontic irrigant. Herbal preparations can be derived from the root, leaves, seeds, stem, and flowers. The PubMed database search revealed that the reference list for natural medicaments featured 1480 articles and in dentistry 173 articles. A forward search was undertaken on the selected articles and author names. This review focuses on various natural drugs and products as well as their therapeutic applications when used as phytomedicine in dentistry. PMID:25558153

Based on the current shortage of genuine/false authentication and quality evaluation in the molecular identification, and the weak functional gene research in the establishment of two-dimensional molecular markering methods for Chinese materia medica, the authors proposed a new method, the bimolecular marking methods (BIMM) for Chinese materia medica, combining DNA marker and metabolomics marker, that could simultaneously research the species and quality differences at the molecular level at the present stage. The authors introduced the concept, principle, methods, and technical process of BIMM, and summarized the technical advantages in this paper. Meanwhile, the application of BIMM in the identification of multiple sources of Chinese materia medica, years-identification, different locations, elite germplasm research, discovery of new drugs resources, protection of new varieties was also discussed. As a supplement of two-dimensional molecular markering method for Chinese materia medica, BIMM would not only expand connotation of identification of Chinese materia medica but also provide another effective way for quality evaluating.

Listeria monocytogenes (Lm) is a ubiquitous bacterium able to survive and thrive within the environment and readily colonizes a wide range of substrates, often as a biofilm. It is also a facultative intracellular pathogen, which actively invades diverse hosts and induces listeriosis. So far, these two complementary facets of Lm biology have been studied independently. Here we demonstrate that the major Lm virulence determinant ActA, a PrfA-regulated gene product enabling actin polymerization and thereby promoting its intracellular motility and cell-to-cell spread, is critical for bacterial aggregation and biofilm formation. We show that ActA mediates Lm aggregation via direct ActA-ActA interactions and that the ActA C-terminal region, which is not involved in actin polymerization, is essential for aggregation in vitro. In mice permissive to orally-acquired listeriosis, ActA-mediated Lm aggregation is not observed in infected tissues but occurs in the gut lumen. Strikingly, ActA-dependent aggregating bacteria exhibit an increased ability to persist within the cecum and colon lumen of mice, and are shed in the feces three order of magnitude more efficiently and for twice as long than bacteria unable to aggregate. In conclusion, this study identifies a novel function for ActA and illustrates that in addition to contributing to its dissemination within the host, ActA plays a key role in Lm persistence within the host and in transmission from the host back to the environment.

By investigating the mainstream works of herbal classics of successive ages, it is found that adulteration of Chinese materia medica appeared early in ancient China. The main methods of adulteration was producing fraud medicines in the Northern-Southern Dynasties, fake medicines began to appear in the Tang Dynasty, and status of adulteration of Chinese materia medica ran unchecked since the Ming and Qing Dynasty. By statistics, there were 76 kinds of adulteration varieties before the Republican period. The main varieties were precious drugs, animal drugs and artifacts. Commonly methods used in the process included forging and adulterating, dealing with 11 kinds and 68 kinds respectively. Adulteration probably lead to the result of imposing the changes of the used medicinal parts of Herba Pogostemonis; Radix Aconiti Lateralis prepared by adding salt, Radix Angelica Sinensis processed by wine, and Radix Astragalis seu Hedysaris processed with bee honey. However, the root cause of adulteration in Chinese materia medica was the dissociation of professional physician and pharmacist, resulting in the ignorance of medical practitioners became unable to recognize Chinese materia medica; and the immorality of medicinal merchants. Besides, rating the quality of materia medica based on its producing areas without differentiating the false from the genuine may also contribute to this result passively.

Citrus medica cv. 'liscia' and C. medica cv. 'rugosa' are two taxa of citron, belonging to the biodiversity of South Italy, in particular of Amalfi Coast, in the Campania region. The chemical composition of the essential oils (EOs) from fruit peels of both C. medica cultivars was studied by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analyses. In all, 100 compounds were identified, 82 for C. medica cv. 'liscia', accounting for 91.4% of the total oil, and 88 for C. medica cv. 'rugosa', accounting for 92.0% of the total oil. Monoterpene hydrocarbons are the main constituents in both oils of C. medica cv. 'liscia' (79.1%) and C. medica cv. 'rugosa' (80.2%). In both oils, limonene (67.2%-62.8%) and camphene (8.5%-10.9%) are the main constituents. The antimicrobial activity of the EOs was assayed against some bacterial strains: Bacillus cereus (DSM 4313), Bacillus cereus (DSM 4384), Staphylococcus aureus (DSM 25693), Pseudomonas aeruginosa (ATCC 50071), and Escherichia coli (DSM 8579). Low concentrations of C. medica cv. 'rugosa' EO showed an inhibitory effect on P. aeruginosa and higher concentrations inhibited more B. cereus (4384) and E. coli than S. aureus. The cytotoxicity of the EO was evaluated against SH-SY5Y cell line. The influence of the EO on the expression of adenylate cyclase 1 (ADCY1) was also studied. The antimicrobial activity registered confirm their traditional uses as food preserving agents and led us to hypothesize the possible use of these oils as antimicrobials. The alterations in ADCY1 expression suggested a role for limonene in effects on the central nervous system.

Cognitive task analysis (CTA) is a set of methods for identifying cognitive skills, or mental demands, needed to perform a task proficiently. The product of the task analysis can be used to inform the design of interfaces and training systems. However, CTA is resource intensive and has previously been of limited use to design practitioners. A streamlined method of CTA, Applied Cognitive Task Analysis (ACTA), is presented in this paper. ACTA consists of three interview methods that help the practitioner to extract information about the cognitive demands and skills required for a task. ACTA also allows the practitioner to represent this information in a format that will translate more directly into applied products, such as improved training scenarios or interface recommendations. This paper will describe the three methods, an evaluation study conducted to assess the usability and usefulness of the methods, and some directions for future research for making cognitive task analysis accessible to practitioners. ACTA techniques were found to be easy to use, flexible, and to provide clear output. The information and training materials developed based on ACTA interviews were found to be accurate and important for training purposes.

Chinese Materia Medica (CMM) decoction dregs are the residues of medicinal materials after decoction. Accurate identification of CMM in decoction dregs will be helpful for exploring the causes of poisoning or other medical incidents arising after the ingestion of CMM decoctions. To determine how decoction affects the characteristics used to authenticate specific CMM, a systematic study was carried out. In this study, two pairs of Materia Medica that are commonly confused-namely, Baizhu (Atractylodis Macrocephalae Rhizoma) and Cangzhu (Atractylodis Rhizoma), Baishao (Paeoniae Alba Radix) and Chishao (Paeoniae Rubra Radix)-were chosen for investigation. Each pair of Materia Medica has similar morphology in appearance, but they have different functions in Chinese clinic. After decoction, with regard to gross morphological characters, the results showed that bark and wood could be easily distinguished. The striation of vessels and fibers became more prominent because of the contraction of parenchymatous cells, but the lignified cells did not. As for the microscopic characteristics, the cells with thickened walls, such as stone cells and fibers, were basically stable. Most of the parenchymatous cells were broken. Crystals of calcium oxalate showed no changes as they were insoluble in water. Starch granules were gelatinized and aggregated in parenchymatous cells. Inulins were substantially reduced in number as they dissolved in water during decoction. According to these changes in morphological and microscopic characteristics after decoction, the dregs of two pairs of Materia Medica could be distinguished. Copyright © 2010 Wiley-Liss, Inc.

Nature of Chinese materia medica is the nucleus in the theory of Chinese material medica, according to the recognition of Traditional Chinese Medicine, which is the character of the drug related on curative effect. Nature and efficacy of a drug is through the medical material, then, physical environment, including the temperature, humidity, atmospheric water, wind, topography, soil, micro-organism, and so on, influence the growth and development of the medical meterial. In this paper, we researched the explanation on nature of Chinese materia medica in the medical books of past dynasties, combined with the modem research, analyzed the relationship between generative reception and physical environmental factors, and discussed the effect of physical environmental factors on nature of Chinese materia medica. We indicated that the formation of Chinese materia medical nature is that the drug receptive the change of physical environmental factors, and resulted by the synthetic action of the factors, such as climate, soil, biology, topography, etc.

To evaluate the influence of the use of digital applications in medicament calculation education for nursing students. An experimental study was developed with a sample of 100 nursing students, who were divided randomly into two groups (use of the Calculation Medicines - CalcMed application - available free on the Internet, n=50) and control (conventional method of the calculator use and pre-math skills, n=50). Both groups were assessed before and after the application of the teaching strategy through a test with ten specific questions of medicament calculations. The study group showed a mean score of 8.14 versus an average of 5.02 in the control group. The average time of test execution was faster in the study group compared to the control group (15.7 versus 38.9 minutes). The strategy of using this application positively influences learning and enables greater security in the implementation of medicament calculations.

Standards of commodity classes of Chinese materia medica is an important way to solve the "Lemons Problem" of traditional Chinese medicine market. Standards of commodity classes are also helpful to rebuild market mechanisms for "high price for good quality". The previous edition of commodity classes standards of Chinese materia medica was made 30 years ago. It is no longer adapted to the market demand. This article researched progress on standards of commodity classes of Chinese materia medica. It considered that biological activity is a better choice than chemical constituents for standards of commodity classes of Chinese materia medica. It is also considered that the key point to set standards of commodity classes is finding the influencing factors between "good quality" and "bad quality". The article also discussed the range of commodity classes of Chinese materia medica, and how to coordinate standards of pharmacopoeia and commodity classes. According to different demands, diversiform standards can be used in commodity classes of Chinese materia medica, but efficacy is considered the most important index of commodity standard. Decoction pieces can be included in standards of commodity classes of Chinese materia medica. The authors also formulated the standards of commodity classes of Notoginseng Radix as an example, and hope this study can make a positive and promotion effect on traditional Chinese medicine market related research.

To study on the differences between chromatopharmacokinetics (pharmacokinetics with fingerprint chromatography) and chromatopharmacodynamics (pharmacodynamics with fingerprint chromatography) of Chinese materia medica formulae to answer the question whether the pharmacokinetic parameters of multiple composites can be utilized to guide the medication of multiple composites. On the base of established four chromatopharmacology (pharmacology with chromatographic fingerprint), the pharmacokinetics, and pharmacodynamics were analyzed comparably on their mathematical model and parameter definition. On the basis of quantitative pharmacology, the function expressions and total statistical parameters, such as total zero moment, total first moment, total second moment of the pharmacokinetics, and pharmacodynamics were analyzed to the common expressions and elucidated results for single and multiple components in Chinese materia medica formulae. Total quantitative pharmacokinetic, i.e., chromatopharmacokinetic parameter were decided by each component pharmacokinetic parameters, whereas the total quantitative pharmacodynamic, i.e., chromatopharmacodynamic parameter were decided by both of pharmacokinetic and pharmacodynamic parameters of each components. The pharmacokinetic parameters were corresponded to pharmacodynamic parameters with an existing stable effective coefficient when the constitutive ratio of each composite was a constant. The effects of Chinese materia medica were all controlled by pharmacokinetic and pharmacodynamic coefficient. It is a special case that the pharmacokinetic parameter could independently guide the clinical medication for single component whereas the chromatopharmacokinetic parameters are not applied to the multiple drug combination system, and not be used to solve problems of chromatopharmacokinetic of Chinese materia medica formulae.

Bi-directional regulation is referred to a balancing effect of both acu-moxibustion and Chinese materia medica interventions when the human body is experiencing a hyperactivity or hypoactivity due to abnormal intrinsic or external factors. In the present paper, the authors analyze their identical and different characteristics from: 1) definition; 2) characters of regulative effects of acu-moxibustion therapy: A) differentiation of meridian and zangfu-organs being the basis of treatment, B) four factors (acupoint-location, body's functional state, acupoint-formula and needle-manipulation techniques) dependant, C) entirety regulation, and D) centrotaxis modulation; 3) characters of Chinese materia medica intervention: including a) correspondence between the drug property and the syndrome being the basis of the regulative effect, b) multi-factors [components (antagonist and agonist), combination, dosages and processing quality of Chinese materia medica, and functional state of the human body] dependant, c) entirety regulation, and d) both centrotaxis and deviation adjustment. In one word, the bi-directional regulation effect is one of the basic characteristics of both acu-moxibustion and Chinese materia medica in clinical practice, but their basis and modes for inducing effects are different.

Whether indeed Fudao(Chinese characters) is Fudao(Chinese characters)? By reviewing the genuine evolution of A. argyi, doing textual research on Fudao(Chinese characters) and combing with field survey data of national census of Chinese Materia Medica resources, this paper concluded that the word Fudao(Chinese characters) firstly emerged in Figure Canon of Chinese Materia Medica(Bencao tujing) of Susong in Song dynasty and was applied in later generations, but the implication was not clear, then emerged both Tangyin and Fudao(Chinese characters) in Compendium of Materia Medica(Bencao gangmu). The place Fudao(Chinese characters) is one of the graves of Bianque, that existed from Shang and Zhou dynasty and never changed until now, the A. argyi of Tangyin was famous from the grave of Bianque in Fudao(Chinese characters), which could infer that Lishizhen considered Fudao (Chinese characters) was Fudao(Chinese characters) indeed, and the origin of northern A. argyi was Fudao(Chinese characters) in Tangyin county.

Bhat, Kishore G; Sogi, Suma

2016-01-01

Aims The aim of this study was to determine the relative antimicrobial effectiveness of these endodontic medicaments and various vehicles using an agar well diffusion assay. Materials and methods Double Antibiotic Paste(DAP), modified DAP, 2% Chlorhexidine gluconate and their combination with four vehicles namely Polyethylene glycol 400 (PEG), Propylene glycol (PG), combinations of PG with PEG and lastly Glycerine were tested using agar well diffusion assay. The minimum bactericidal concentration was noted against four standard strains of organisms ie Streptococcus mutans ATCC( American Type Culture Collection) 25175, Staphylococcus aureus ATCC 12598, Enterococcus faecalis ATCC 35550 and Eschericia coli ATCC 25922. Successful endodontic therapy depends upon thorough disinfection of root canals. In some refractory cases, routine endodontic therapy is not sufficient, so intracanal medicaments are used for proper disinfection of canals. Issues of resistance, limited spectrum of activity and lack of antifungal properties, the hunt for the ideal intracanal medicament continues. In this regard, the vehicles used to form the pastes play a supportive role by forming the appropriate consistency for placement and may dramatically influence their chemical characteristics like their solubility and diffusion. Thus, inorder to use safer and equally effective intracanal medicaments, Chlorhexidine gluconate is being unveiled in this study. Results The difference between the four vehicles when combined with the same endodontic medicament studied above is nonsignificant (NS) except against Porphyromonas gingivalis. Propylene glycol is significantly effective than Glycerine when used with DAP ie C+M medicament combination. (p = 0.029) Conclusion 2% chlorhexidine gluconate and modified DAP can definitely replace DAP and triple antibiotic paste as end-odontic medicaments with chlorhexidine having an added advantage of bactericidal action, substantivity, biocompatibility, low toxicity

Trope, M

1990-10-01

The purpose of the study was to compare the effect of three intracanal medicaments on the incidence of post-instrumentation flare-ups. All teeth were instrumented to a predetermined minimum size using a 0.5% solution of sodium hypochlorite as the irrigant. Formocresol, Ledermix, and calcium hydroxide were placed in strict sequence irrespective of the presence or absence of symptoms or radiographic signs of apical periodontitis. The patients were given written post-operative instructions and a prescription for 600 mg ibuprofen to be taken if mild to moderate pain developed. If severe pain and/or swelling developed the patient was instructed to call the office immediately and was considered to have had a flare-up. Twelve flare-ups occurred in teeth with radiographic signs of apical periodontitis; none in teeth without periapical radiolucencies. Six of the twelve flare-ups occurred in retreatment cases and the other six occurred in teeth without previous endodontic treatment. No significant difference was found in the flare-up rate among the three intracanal medicaments.

To determine the viability of Enterococcus faecalis in infected human root dentine in vitro after exposure to root canal medicaments based on chlorhexidine and octenidine. Human root segments (n = 40) were infected with E. faecalis for 8 weeks. Root dentine samples (rd) collected at week 4 served as individual baseline values. At week 8, the root segments were randomly divided into four test groups (n = 10 each) for the placement of one of the following medicaments in the root canals: calcium hydroxide paste (CH), chlorhexidine gel (CHX-gel) (5.0%), chlorhexidine/gutta-percha points (CHX-GP) (active points(®) ; Roeko, Langenau, Germany) and octenidine gel (OCT-gel) (5.0%) followed by incubation for 4 weeks. The effect on E. faecalis viability was assessed by two fluorescent dyes (syto 9/propidium iodide) to determine the 'proportion of viable bacteria' (PVB%) and number of 'colony-forming units' (CFU). Mean values and 95% confidence intervals (CI) were calculated for PVB% and log CFU, and the difference between groups was established. Viable and dead bacterial cells were detected in all 'rd' samples at weeks 4 and 8. The treatment with CHX-gel, CHX-GP and OCT-gel resulted in significantly lower PVB% values with 15.4%, 3.5% and 0%, respectively. No growth (CFU) was recorded for these samples at week 12. When medicated by CH, the PVB% was increased without a corresponding change in CFUs. In contrast to calcium hydroxide, both CHX - and octenidine-based intracanal medicaments were effective in decreasing the viability of E. faecalis. OCT showed the most favourable results and may have potential as an endodontic medicament. © 2012 International Endodontic Journal.

Written records of oral medical traditions have had significant impact on the development of medicine and the pharmacopoeias. Modern ethnobotanical studies in Europe and the Mediterranean region, however, have so far largely overlooked the richness and accuracy of historic sources and ignored their probable influence on the development of today's local traditional medicines. Here, we explore the common fundament of traditional knowledge for the medicinal plant uses in Sardinia and Sicily by comparing the selection of medicinal species and specific uses with those of Dioscorides' De Materia Medica. We use (i) a quantification of citations for medicinal species mentioned in ethnobotanical studies conducted in Sardinia and Sicily (ii) a comparison of the flora and medicinal flora with a chi(2)-test (iii) a binomial approach recently introduced into ethnobotany (iv) a comparison of the most frequently used species with the indications cited in Dioscorides' De Materia Medica (v) and a crosscheck of all mentioned species with their appearance in Berendes' translation of De Materia Medica. We identified a core group of 170 medicinal species used on either islands, which accumulate 74% of all citations and are best represented in De Materia Medica. The 15 most frequently used species of both islands demonstrate intriguing parallels for indications with Dioscorides' work. The ethnopharmacopoeia of Sicily and Sardinia are shallow stereotypes of the different editions of De Materia Medica and talking of oral tradition in this respect is a contradiction. The medicinal species of Sardinia and Sicily are largely widespread and common species, including many weeds, which are not facing threat of extinction. Therefore, using traditional medicinal practices as an argument for conservation biology or vice versa is not scientifically sound.

Metabonomics, a newly developing subject secondary to genomics, transcriptomics, and proteomics, is an important constituent part of systems biology. It is believed to be the final direction of the systems biology. It can be directly applied to understand the physiological and biochemical states by its "metabolome profile" as a whole. Therefore, it can provide a huge amount of information different from those originating from other "omics". In the modernization of Chinese materia medica research, the application of metabonomics methods and technologies has a broad potential for future development. Especially it is of important theoretical significance and application value in holistic efficacies evaluation, active ingredients studies, and safety research of Chinese materia medica.

Dry retraction cords help to displace the gingiva and also to absorb the gingival crevicular fluid and saliva to maintain a dry field. When used along with medicaments whether these medicaments help to improve the absorption of fluid or affect the fluid absorption by decreasing the efficiency of the retraction cord is unknown. The aim of the study was to know the effect of various medicaments on the fluid absorbency of the retraction cords and also, to know whether the thickness of the retraction cords influences it's fluid absorbency. A total of 90 samples of 5cm length retraction cords were taken. Cords were divided into 30 samples for each cord thickness of 0, 1 and 2. Of these 30 samples, 10 samples were used to measure dry weight (Group I), 10 samples were immersed in 15.5% ferric sulfate (Group II) and remaining 10 samples were immersed in 10% aluminium chloride (Group III) for a period of 20 minutes. The excess medicament was removed by blotting paper. Initial weight was recorded. Following this, five cords from each group were immersed in plasma solution and remaining in artificial saliva for 10 minutes. Then these were taken out and measured. The amount of the fluid absorbed was determined by subtracting the weight before fluid immersion (weight after immersion in test medicament) from the weight after fluid immersion (weight after immersion in plasma or artificial saliva). The study was analyzed through one-way ANOVA and Bonferroni post-hoc comparisons for pair wise differences. When immersed in medicaments, there is a significant difference in absorption of fluids (artificial saliva and plasma) between the untreated dry cord and cord treated with 15.5% ferric sulfate (p<0.05). But, there was no significant difference in fluid absorption between the dry untreated cord and cord treated with 10% aluminum chloride and between cords treated with 15.5% ferric sulfate and 10% aluminum chloride. Ferric sulfate (15.5%) is a better medicament for absorption of

DNA barcodes have been increasingly used in authentication of medicinal plants, while their wide application in materia medica is limited in their accuracy due to incomplete sampling of species and absence of identification for materia medica. In this study, 95 leaf accessions of 23 species (including one variety) and materia medica of three Pharmacopoeia-recorded species of Angelica in China were collected to evaluate the effectiveness of four DNA barcodes (rbcL, matK, trnH-psbA and ITS). Our results showed that ITS provided the best discriminatory power by resolving 17 species as monophyletic lineages without shared alleles and exhibited the largest barcoding gap among the four single barcodes. The phylogenetic analysis of ITS showed that Levisticum officinale and Angelica sinensis were sister taxa, which indicates that L. officinale should be considered as a species of Angelica. The combination of ITS + rbcL + matK + trnH-psbA performed slight better discriminatory power than ITS, recovering 23 species without shared alleles and 19 species as monophyletic clades in ML tree. Authentication of materia medica using ITS revealed that the decoction pieces of A. sinensis and A. biserrata were partially adulterated with those of L. officinale, and the temperature around 80 °C processing A. dahurica decoction pieces obviously reduced the efficiency of PCR and sequencing. The examination of two cultivated varieties of A. dahurica from different localities indicated that the four DNA barcodes are inefficient for discriminating geographical authenticity of conspecific materia medica. This study provides an empirical paradigm in identification of medicinal plants and their materia medica using DNA barcodes. PMID:24961287

In this study, 95 leaf accessions of 23 species (including one variety) and materia medica of three Pharmacopoeia-recorded species of Angelica in China were collected to evaluate the effectiveness of four DNA barcodes (rbcL, matK, trnH-psbA and ITS). Our results showed that ITS provided the best discriminatory power by resolving 17 species as monophyletic lineages without shared alleles and exhibited the largest barcoding gap among the four single barcodes. The phylogenetic analysis of ITS showed that Levisticum officinale and Angelica sinensis were sister taxa, which indicates that L. officinale should be considered as a species of Angelica. The combination of ITS + rbcL + matK + trnH-psbA performed slight better discriminatory power than ITS, recovering 23 species without shared alleles and 19 species as monophyletic clades in ML tree. Authentication of materia medica using ITS revealed that the decoction pieces of A. sinensis and A. biserrata were partially adulterated with those of L. officinale, and the temperature around 80 °C processing A. dahurica decoction pieces obviously reduced the efficiency of PCR and sequencing. The examination of two cultivated varieties of A. dahurica from different localities indicated that the four DNA barcodes are inefficient for discriminating geographical authenticity of conspecific materia medica. This study provides an empirical paradigm in identification of medicinal plants and their materia medica using DNA barcodes. © 2014 The Authors.

The aim of the present study was to investigate antibacterial characteristic and Enterococcus faecalis (E. faecalis) biofilm suppression effect of different vehicles of calcium hydroxide as intracanal medicaments in short and long-term. Fifty-four human single-root teeth were contaminated with E. faecalis bacteria. The teeth were randomly divided into three experimental (n=16) and one control group (n=6). Each group was then exposed to various intracanal medicaments, namely calcium hydroxide paste (group 1), calcium hydroxide with chlorhexidine (group 2), calcium hydroxide with silver nanoparticles suspension (AgNPs) (group 3), and saline as the control group (group 4). Cultures were made from each group after one week and one month, and the number of colonies was counted. Moreover, a sample of each group was examined under electron microscope. Kruskal-Wallis test served for inter-group comparisons, and Mann-Whitney test served for comparison between the two incubation periods. All the intracanal medicaments resulted in significant decrease in number of colonies compared to control group in both incubation periods. After one week, the mixture of calcium hydroxide and AgNPs was the most effective medicament against E. faecalis bacteria (p<.05). No significant difference in antibacterial effect of the medicaments existed after one month incubation period (p>.05). AgNPs was more effective on the E. faecalis biofilm than other tested vehicles in short-term medication. AgNPs seems to have a good potential to be used as an appropriate vehicle of calcium hydroxide in order to eliminate of E. faecalis biofilm from human dentine in short-term.

Curidium Medica, plc is a personalized medicine company intent on developing targeted medicines and their associated companion diagnostics to treat patients more effectively and safely. Through the use of its proprietary gene-expression analysis tool, Homomatrix ® , Curidium aims to reveal different patient subgroups characterized by distinct underlying disease mechanisms. This is anticipated to lead to the identification of diagnostics to subclassify patients within heterogeneous disease populations and improved therapies for different patient subgroups, ultimately resulting in the development of personalized medicines using companion diagnostics and targeted treatments. The company's initial focus on diseases of the CNS has resulted in the identification of a blood diagnostic tool, PsychINDx™, which classifies patients with schizophrenia/bipolar disorder into four subgroups. PsychINDx may have the potential to improve the treatment of patients with schizophrenia/bipolar disorder. Curidium aims to continue to use this approach to improve patient treatments in a variety of therapeutic areas and heterogeneous diseases. The first such additional application using Homomatrix has been initiated within a strategic research alliance with Takeda (Osaka, Japan) in the area of major depressive disorder.

The survey of traditional knowledge related to Chinese materia medica resources is the important component and one of the innovative aspects of the fourth national survey of the Chinese materia medica resources. China has rich traditional knowledge of traditional Chinese medicine (TCM) and the comprehensive investigation of TCM traditional knowledge aims to promote conservation and sustainable use of Chinese materia medica resources. Building upon the field work of pilot investigations, this paper introduces the essential procedures and key methods for conducting the survey of traditional knowledge related to Chinese materia medica resources. The essential procedures are as follows. First is the preparation phrase. It is important to review all relevant literature and provide training to the survey teams so that they have clear understanding of the concept of traditional knowledge and master key survey methods. Second is the field investigation phrase. When conducting field investigations, survey teams should identify the traditional knowledge holders by using the 'snowball method', record the traditional knowledge after obtaining prior informed concerned from the traditional knowledge holders. Researchers should fill out the survey forms provided by the Technical Specification of the Fourth National Survey of Chinese Materia Medica Resources. Researchers should pay particular attention to the scope of traditional knowledge and the method of inheriting the knowledge, which are the key information for traditional knowledge holders and potential users to reach mutual agreed terms to achieve benefit sharing. Third is the data compilation and analysis phrase. Researchers should try to compile and edit the TCM traditional knowledge in accordance with intellectual property rights requirements so that the information collected through the national survey can serve as the basic data for the TCM traditional knowledge database. The key methods of the survey include regional

A collection of nodule isolates from Medicago polymorpha obtained from southern and central Portugal was evaluated by M13-PCR fingerprinting and hierarchical cluster analysis. Several genomic clusters were obtained which, by 16S rRNA gene sequencing of selected representatives, were shown to be associated with particular taxonomic groups of rhizobia and other soil bacteria. The method provided a clear separation between rhizobia and co-isolated non-symbiotic soil contaminants. Ten M13-PCR groups were assigned to Sinorhizobium (Ensifer) medicae and included all isolates responsible for the formation of nitrogen-fixing nodules upon re-inoculation of M. polymorpha test-plants. In addition, enterobacterial repetitive intergenic consensus (ERIC)-PCR fingerprinting indicated a high genomic heterogeneity within the major M13- PCR clusters of S. medicae isolates. Based on nucleotide sequence data of an M13-PCR amplicon of ca. 1500 bp, observed only in S. medicae isolates and spanning locus Smed_3707 to Smed_3709 from the pSMED01 plasmid sequence of S. medicae WSM419 genome's sequence, a pair of PCR primers was designed and used for direct PCR amplification of a 1399-bp sequence within this fragment. Additional in silico and in vitro experiments, as well as phylogenetic analysis, confirmed the specificity of this primer combination and therefore the reliability of this approach in the prompt identification of S. medicae isolates and their distinction from other soil bacteria.

The first material recorded about hair charcoal is seen in Nei jing ( Inner Canon ). It has a history of over 2 000 years for the carbonization of Chinese materia medica. There were controversies on this matter and its clinical application was seldom seen and underdeveloped. After the Yuan Dynasty, the main theory of carbonic herbs for hemostasis, and keeping the nature of the medicines after carbonization was gradually formed, and physicians of generations began to conduct in-depth research. Through repeated practice and verification, people summed up the suitable species of Chinese materia medica and its principle for carbonization. The methods and degree of carbonization of Chinese materia medica are reasonably discussed, with its principle and basis for application primarily interpreted.

By Zhuang materia medica, it refers to application of medicines under the instructions of medical theory of Zhuang ethnic group. By studying the pronunciation of the Zhuang language for the terms "zhu yu", "bai jiu", and "mi gu" included in the shan hai jing nan shan jing (The Classic of Southern Mountain in Classic of Seas and Mountains) carried out by the Zhuang scholar Qin Bao-lin, it was concluded that the Zhuang minority already applied medicines early in the pre-Qin period. Through extensive cultural communication in different regions in the Wei-Jin-Southern-Northern Dynasties, the medicinal experiences of the Zhuang ethnic group appeared in ancient literature. The antidotes in Zhou hou fang (Handbook of Prescriptions for Emergency), for instance, were mostly coming from the Southern Ridge area. Since the Sui-Tang Dynasties, many materia medica recorded in the herbal works and regional gazetteers, and Annals such as the Guangxi Annals, Gazetteer of Nanning County, and Gazetteer of Liuzhou County, Gazetteer of Binzhou County etc., also carry medicines such as Cinnamom twigs and bark, and mangosteen etc., which are similar to those of the Zhuang medicines. In the Republican period, many manuscripts of Zhuang medicines appeared. After 1949, many institutions of Zhuang medicine were set up successively, including The Nanning Medical Institute, The Medical Institute of Wuzhou, The Medical Institute of Guilin. Systematic researches were also done, with publication of a series of works on Zhuang materia medica. Reformation of part of the prescription forms of Zhuang medicine were also accomplished.

In the second half of the nineteenth century several ophthalmological journals appeared (Germany, England, France, United States). In the northern countries (Denmark, Finland, Norway, Sweden) an initiative lead to 'Nordisk ophthalmologisk Tidsskrift' published in the scandinavian languages in the years 1889-92. The 'driving force' behind the journal was the first professor in Ophthalmology in Copenhagen, Dr. Edmund Hansen Grut. The purpose with this presentation is to give the background for the rise and fall of the journal which was an attempt to promote Nordic Ophthalmology. The authors turned out, however, to be mainly those involved as editors. The journal never gained broad acceptance and it simply stopped in 1892, without any closing remarks. In spite of its short life the journal should be remembered for the very first publication on the arcuate scotoma, the Bjerrum scotoma from 1889. Although shortlived the initiative was not in vain, as can be read in the preface to the very first volume of Acta ophthalmologica. © 2011 The Author.

Symbiotic nitrogen fixation (SNF) between rhizobia and legumes requires metabolic coordination within specialized root organs called nodules. Nodules formed in the symbiosis between S. medicae and barrel medic (M. truncatula) are indeterminate, cylindrical, and contain spatially distinct developmental zones. Bacteria in the infection zone II (ZII), interzone II-III (IZ), and nitrogen fixation zone III (ZIII) represent different stages in the metabolic progression from free-living bacteria into nitrogen fixing bacteroids. To better understand the coordination of plant and bacterial metabolism within the nodule, we used liquid and gas chromatography coupled to tandem mass spectrometry (MS) to observe protein and metabolite profilesmore » representative of ZII, IZ, ZIII, whole-nodule, and primary root. Our MS-based approach confidently identified 361 S. medicae proteins and 888 M. truncatula proteins, as well as 160 metabolites from each tissue. The data are consistent with several organ- and zone-specific protein and metabolite localization patterns characterized previously. Here, we used our comprehensive dataset to demonstrate how multiple branches of primary metabolism are coordinated between symbionts and zones, including central carbon, fatty acid, and amino acid metabolism. For example, M. truncatula glycolysis enzymes accumulate from zone I to zone III within the nodule, while equivalent S. medicae enzymes decrease in abundance. We also show the localization of S. medicae's transition to dicarboxylic acid-dependent carbon metabolism within the IZ. The spatial abundance patterns of S. medicae fatty acid (FA) biosynthesis enzymes indicate an increased demand for FA production in the IZ and ZIII as compared to ZI.

Objective:To determine the effect of different retraction cord medicaments on surface detail reproduction of polyvinyl siloxane impression materials and compare this effect on any two brands of commercially available polyvinyl siloxane impression materials. Material and methods: Four stainless steel dies were made according to ADA specification no.19. Three dies were treated with aluminium chloride (5%), ferric sulphate (13.3%) and epinephrine (0.1%) while the fourth one was left untreated to serve as control. Two impression materials (Dentsply and 3M ESPE) were used. Results: All the three medicaments adversely affected the surface detail reproduction of both the brands of the polyvinyl siloxane impression materials. These effects were statistically significant as compared to untreated control. The impressions of 3M ESPE brand have shown better surface detail reproduction as compared to Dentsply impression material. Conclusion: Surface detail reproduction of the polyvinyl siloxane impression materials is adversely affected by the retraction cord medicaments. The presence of moisture or any traces of the medicaments should be removed from the tooth surface to provide a dry field for the correct reproduction of the surface detail of these materials. Key words:Polyvinyl Siloxane, retraction cord medicaments, surface detail reproduction. PMID:24455069

Mutations in skeletal muscle α-actin 1-encoding gene (ACTA1) cause autosomal dominant or recessive myopathies with marked clinical and pathological heterogeneity. Patients typically develop generalized or limb-girdle pattern of weakness, but recently a family with scapuloperoneal myopathy was reported. We describe a father and 2 children with childhood-to-juvenile onset distal myopathy, carrying a novel dominant ACTA1 variant, c.757G>C (p.Gly253Arg). Father had delayed motor development and developed significant proximal weakness later in life; he was initially misdiagnosed as having spinal muscular atrophy based on electromyographic findings. His children had predominant anterior distal leg and finger extensor involvement. Nemaline rods were abundant on the daughter's biopsy, absent on the father's initial biopsy, and extremely rare on the father's subsequent biopsy a decade later. The father's second biopsy also showed myofibrillar pathology and rare fibers with actin filament aggregates. The present family expands the spectrum of actinopathy to include a distal myopathy.

The functional ingredients in Chinese materia medica are the main active substance for traditional Chinese medicine and most of them are secondary metabolites derivatives. Until now,the main method to obtain those functional ingredients is through direct extraction from the Chinese materia medica. However, the income is very low because of the high extraction costs and the decreased medicinal plants. Synthetic biology technology, as a new and microbial approach, can be able to carry out large-scale production of functional ingredients and greatly ease the shortage of traditional Chinese medicine ingredients. This review mainly focused on the recent advances in synthetic biology for the functional ingredients production. Copyright© by the Chinese Pharmaceutical Association.

For more systematic medical education, Dr. O. R. Avison translated medical textbooks into Korean since he took charge of Jejungwon in 1893. The first book he chose was Anatomy of the Human Body. He, however, failed to see it published after losing its manuscript twice. Instead, Materia Medica Part. I was brought into the world first in 1905, for which he translated Materia Medica and Therapeutics written by John Mitchell Bruce from the U. K. At that time, this book was in widespread use in the English-speaking world as a textbook for pharmacology. It is also assumed that Avison used it as a textbook for his classes in Canada before coming to Korea. For the publication of Materia Medica Part. I, Avison did not translate Bruce's original text in full, but translated only the selected passages. He followed a principle of using Korean alphabets (Hangeul) only, but in combination with Chinese characters, if necessary. He put pharmacological terms into existing Korean equivalents or newly coined words, but also borrowed many from Japanese terms. That's because Japan moved faster to introduce Western medicine than Korea did, so that many pharmacological terms could be defined and arranged more systematically in Japanese. Moreover, Japan took such a favorable stance in the state of international affairs that many of Japanese-style terms could be introduced into Korea in most fields including medicine. By translating Materia Medica Part. I in cooperation with his disciple KIM Pilsoon after Gray's Anatomy of the Human Body, Avison tried to lay groundwork for providing medical education in Korea based on the British-American medicine. It is assumed that he took an independent stance in selecting and translating Western medical textbooks on his own rather than simply accepting the existing Chinese translation of Western medical textbooks. Despite all his efforts, he might find it difficult to translate all the Western medical terms into Korean within a short period of time

TetR-dependent gene regulation in intracellular Listeria monocytogenes demonstrates the spatiotemporal surface distribution of ActA.

To enable specific and tightly controlled gene expression both in vitro and during the intracellular lifecycle of the pathogen Listeria monocytogenes, a TetR-dependent genetic induction system was developed. Highest concentration of cytoplasmic TetR and best repression of tetO-controlled genes was obtained by tetR expression from the synthetic promoter Pt 17 . Anhydrotetracycline (ATc) as inducer permitted concentration-dependent, fine-tuned expression of genes under control of the tetO operator and a suitable promoter. The actin-polymerizing ActA protein represents a major virulence factor of L. monocytogenes, required for actin-based motility and cell-to-cell spread in infected host cells. To be able to observe its spatial and temporal distribution on intracellular L. monocytogenes cells, conditional mutants featuring actA placed under TetR control were used to infect PtK2 epithelial cells. Following induction at different time intervals, the subsequent recruitment of actin by L. monocytogenes could be monitored. We found that cells displayed functional ActA after approximately 15 min, while formation of polarized actin tail was complete after 90-120 min. At this point, intracellular motility of the induced mutants was indistinguishable from wild-type bacteria. Interestingly, de novo ActA synthesis in intracellular Listeria also demonstrated the temporal, asymmetric redistribution of the membrane-anchored proteins from the lateral walls toward the cell poles. © 2017 John Wiley & Sons Ltd.

The aim was to determine the effect of four different intracanal medicaments on the apical seal of the root canal system in vitro. Fifty freshly extracted intact human permanent maxillary central incisors were collected, stored and disinfected. The root canals were prepared to a master apical size of number 50 using step back technique. Depending upon the intracanal medicament used, the teeth were divided randomly into five groups of 10 teeth each including one control group and four experimental groups. Group A: No intracanal medicament. Group B: Calcium hydroxide powder mixed with distilled water. Group C: Calcium hydroxide gutta percha points (calcium hydroxide points). Group D: 1% chlorhexidine gel (hexigel). Group E: Chlorhexidine gutta percha points (Roeko Activ Points). The medication was left in canals for 14 days. Following removal of the intracanal medicament, all the groups were obturated with lateral compaction technique. The apical leakage was then evaluated using dye extraction method with the help of a spectrophotometer. RESULTS were statistically analyzed using Kruskal-Wallis and Mann-Whitney U-test, which showed statistically significant difference among the five groups tested. It can be concluded from this study that the control group showed least amount of leakage, whereas the 1% chlorhexidine gel group showed maximum amount of leakage. Apical leakage was observed with all the experimental groups with little variations in between them. Under the parameters of this study, it can be concluded that use of intracanal medicaments during endodontic treatment has a definite impact on the apical seal of the root canal system.

It was discovered that four properties showed significant positive correlations with tastes of "pungent and sweet" , channels of "spleen" , "stomach" , "kidney" and "toxicity" , but also showed significant negative correlations with tastes of "bitter" and "light" and six channels such as "large intestine" , "heart", "bladder" , "gallbladder" , "small intestine" and "lung" (in descending order of correlation ) (P <0. 01). It was indicated that the more hot the Chinese medicine nature, the more possible it contained "toxicity" , tastes of "pungent" and "sweet" , and the more possible it was belong to channels of "spleen" , "stomach" and "kidney". As well, the more cold the Chinese medicine nature, the more possible it contained tastes of "bitter" and "light", and the more possible it was belong to six channels such as "large intestine", etc.

Using Chinese Materia Medica (CM) as injections is an innovation that is proving effective in extensive clinical use in Mainland China. However, recent reports have focused on adverse reactions, ignoring the considerable successes of these preparations. In order to achieve balance in the media and in the minds of the public, we suggest the first step is to clarify the concepts of and differences between adverse drug reactions (ADR) and adverse events (AE) for all concerned-the public, medical practitioners, government officials, and lawmakers. Second, the State Food and Drug Administration should raise the requirements for Chinese Materia Medica Injection (CMI) registration and license approval and emphasize the importance of evidence-based CMI development and evidence-based CMI license approval. Thirdly, drug companies and institutions should reinforce basic research about the quality control of herbs and CMI-drug interactions. Fourth, the Government should clarify the legal responsibilities for CMI approval agencies, CMI developers, medical doctors, and patients. Fifth, the medical association and Government should enhance training for health care professionals concerning the usage of CMIs. And finally sixth, State Food and Drug Administration should monitor the content and quality of the directions for use of CMI. © 2010 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

One of the advantages of biopharmaceutics classification system of Chinese materia medica (CMMBCS) is expanding the classification research level from single ingredient to multi-components of Chinese herb, and from multi-components research to holistic research of the Chinese materia medica. In present paper, the alkaloids of extract of huanglian were chosen as the main research object to explore their change rules in solubility and intestinal permeability of single-component and multi-components, and to determine the biopharmaceutical classification of extract of Huanglian from holistic level. The typical shake-flask method and HPLC were used to detect the solubility of single ingredient of alkaloids from extract of huanglian. The quantitative research of alkaloids in intestinal absorption was measured in single-pass intestinal perfusion experiment while permeability coefficient of extract of huanglian was calculated by self-defined weight coefficient method.

In December 2016, Elsevier launched a new tool that helps measure the citation impact of academic journals, called the CiteScore index. The CiteScore index values for 2015 confirmed the status of Acta Dermatovenerologica Alpina, Pannonica et Adriatica (Acta Dermatovenerol APA) as the leading journal in dermatology and sexually transmitted infections in the region. Sixty-five articles published in Acta Dermatovenerol APA from 2012 to 2014 received a total of 77 citations in 2015, resulting in a CiteScore index value of 1.18 for the journal. More than half of the articles published from 2012 to 2014 received at least one citation in 2015. Acta Dermatovenerol APA performed well in all three categories listed because it is ranked 384th out of 1,549 journals in the category General Medicine (75th percentile), 53rd out of 122 journals in the category Dermatology (56th percentile), and 142nd out of 246 journals in the category Infectious Diseases (42nd percentile).

Neuregulin-1 (NRG-1) includes an extracellular epidermal growth factor-like domain and an intracellular domain (NRG-1-ICD). In response to transforming growth factor-β1, its cleavage by proteolytic enzymes releases a bioactive fragment, which suppresses the vascular smooth muscle cell (VSMC) proliferation by activating ErbB (erythroblastic leukemia viral oncogene homolog) receptor. However, NRG-1-ICD function in VSMCs remains unknown. Here, we characterize the function of NRG-1-ICD and underlying mechanisms in VSMCs. Immunofluorescence staining, Western blotting, and quantitative real-time polymerase chain reaction showed that NRG-1 was expressed in rat, mouse, and human VSMCs and was upregulated and cleaved in response to transforming growth factor-β1. In the cytoplasm of HASMCs (human aortic smooth muscle cells), the NRG-1-ICD participated in filamentous actin formation by interacting with α-SMA (smooth muscle α-actin). In the nucleus, the Nrg-1-ICD induced circular ACTA2 (alpha-actin-2; circACTA2) formation by recruitment of the zinc-finger transcription factor IKZF1 (IKAROS family zinc finger 1) to the first intron of α-SMA gene. We further confirmed that circACTA2, acting as a sponge binding microRNA (miR)-548f-5p, interacted with miR-548f-5p targeting 3' untranslated region of α-SMA mRNA, which in turn relieves miR-548f-5p repression of the α-SMA expression and thus upregulates α-SMA expression, thereby facilitating stress fiber formation and cell contraction in HASMCs. Accordingly, in vivo studies demonstrated that the localization of the interaction of circACTA2 with miR-548f-5p is significantly decreased in human intimal hyperplastic arteries compared with normal arteries, implicating that dysregulation of circACTA2 and miR-548f-5p expression is involved in intimal hyperplasia. These results suggest that circACTA2 mediates NRG-1-ICD regulation of α-SMA expression in HASMCs via the NRG-1-ICD/circACTA2/miR-548f-5p axis. Our data provide a molecular

All previous literatures about Chinese herbal medicines show distinctive traditional Chinese medicine (TCM) flavors. Compendium of Materia Medica is an influential book in TCM history. The TCM flavor theory and flavor standardization principle in this book has important significance for modern TCM flavor standardization. Compendium of Materia Medica pays attention to the flavor theory, explain the relations between the flavor of medicine and its therapeutic effects by means of Neo-Confucianism of the Song and Ming Dynasties. However,the book has not reflected and further developed the systemic theory, which originated in the Jin and Yuan dynasty. In Compendium of Materia Medica , flavor are standardized just by tasting medicines, instead of deducing flavors. Therefore, medicine tasting should be adopted as the major method to standardize the flavor of medicine.

To compare the efficacy of calcium hydroxide powder mixed with 0.2% chlorhexidine digluconate or mixed with normal saline as intracanal medicament in the treatment of apical periodontitis. Subjects were 55 in number aged 17 to 60 years. Two-visit conventional root canal treatment was performed on 70 teeth. The teeth were divided by randomization (balloting) into two groups: control group and experimental group, each with 35 teeth treated with calcium hydroxide mixed with normal saline or with 0.2% chlorhexidine digluconate as intracanal medicament respectively. All treated teeth were evaluated clinically and radiographically for signs and symptom of periapical infection at specified periods postoperatively. Overall efficacy of medicament was rated based on quality guidelines for endodontic treatment by the European Society of Endodontology 2006. A postoperative favorable outcome of 97.1% in the control group and 94.3% in the experimental group was observed at 6-month review. This difference was not statistically significant (p > 0.05). The use of normal saline or 0.2% chlorhexidine digluconate to mix calcium hydroxide used as intracanal medicament during endodontic treatment resulted in high postoperative favorable outcomes. Efficacy of 0.2% chlorhexidine digluconate as a vehicle for mixing calcium hydroxide as an intracanal medicament in the treatment of apical periodontitis is comparable to the efficacy of calcium hydroxide mixed with normal saline.

The most relevant problems related to the management of neurological disorders are (i) the frequent hospitalization in nonspecialist departments, with the need for neurological consultation, and (ii) the frequent requests of GPs for highly specialized investigations that are very expensive and of little value in arriving at a correct diagnosis. In 1996, the Consorzio di Bioingegneria e Informatica Medica in Italy realized the CISNet project (in collaboration with the Consorzio Istituti Scientifici Neuroscienze e Tecnologie Biomediche and funded by the Centro Studi of the National Public Health Council) for the implementation of a national neurological excellence centers network (CISNet). In the CISNet project, neurologists will be able to give on-line interactive consultation and off-line consulting services identifying correct diagnostic/therapeutic procedures, evaluating the need for both examination in specialist centers and admission to specialized centers, and identifying the most appropriate ones.

To compare the antimicrobial activities of Activ Point (Roeko, Langenau, Germany), Calcium Hydroxide Plus Point (Roeko, Langenau, Germany), calcium hydroxide, 1% chlorhexidine gel and bioactive glass (S53P4) against Enterococcus faecalis and Streptococcus mutans. One hundred and twenty extracted single-rooted human teeth were used. After removing the crowns, root canals were prepared by using the Protaper rotary system. Following autoclave sterilization, root canals were incubated at 37 °C with E. faecalis ATCC 29212 and S. mutans RSHM 676 for 1 week. The specimens, which were divided into five treatment groups for each microorganism according to the intracanal medicament used, were tested in 10 experimental runs. In each experimental run, 10 roots were included as treatment, one root as positive control and one root as sterility control. Sterile paper points were utilized to take samples from root canals after the incubation of teeth in thioglycollate medium at 37 °C for 1 week. Samples taken from teeth by sterile paper points were inoculated onto sheep blood agar, and following an overnight incubation, the colonies grown on sheep blood agar were counted and interpreted as colony-forming units. Results were tested statistically by using Kruskal-Wallis and Conover's nonparametric multiple comparison tests. CHX gel (P < 0.001 and P < 0.001), Activ Point (P = 0.003 and P = 0.002) and Ca(OH)₂ (P = 0.010 and P = 0.005) were significantly more effective against E. faecalis than that of Ca(OH)₂ Plus Point and bioactive glass, respectively. On the other hand, compared with Ca(OH)₂ , CHX gel (P < 0.001), and Activ Point (P < 0.001), bioactive glass (P = 0.014) produced significantly lower colony counts of S. mutans. When compared with the positive control, treatment with Ca(OH)₂ Plus Point (P = 0.085 and P = 0.066) did not produce significantly lower colony counts of E. faecalis and S. mutans, respectively.

Endodontic lubricants, irrigants and medicaments help prepare and disinfect root canal systems (RCS) but primary and secondary cases involve different microbes and therefore it is unlikely that one protocol will be effective for both case types. Each individual 'solution' or sequence of'solutions' could play a significant role in each case type, but there are no detailed published guidelines in existence. To help inform clinical practice it was decided to undertake a literature review followed by a UK and Republic of Ireland wide audit on current endodontic'solution' usage within dental schools. The literature review was undertaken under the following headings: pre-op oral rinse; file lubricants; root canal irrigants and intracanal medicaments and provides an evidence base for protocol development for both primary and retreatment cases.The audit project and the protocols developed from the findings of both the literature review and audit will be presented in Part 2.

Our aim was to investigate if: (a) authors of Biochemia Medica meet authorship criteria given by International Committee of Medical Journal Editors (ICMJE), (b) authorship violations are more frequent in submissions containing some type of scientific misconduct. Self-reported authorship contributions regarding the three ICMJE criteria were analysed for all submissions to Biochemia Medica (February 2013-April 2015) which were forwarded to peer-review. To test the differences in frequencies we used Chi-squared test. P<0.05 was considered statistically significant. 186 manuscripts were authored by 804 authors. All ICMJE criteria were met by 487/804 (61%) authors. The first and the last author met all the criteria more frequently than those authors in between (P<0.001). The degree to which ICMJE criteria was met for the first author did not differ between manuscripts authored by only one author and those authored by >1 author (P=0.859). In 9% of the manuscripts ICMJE criteria were not met by a single author. Authors of the 171/186 manuscripts declared that all persons qualify for authorship but only 49% of them satisfied all ICMJE criteria. Authors have failed to acknowledge contributors in 88/186 (47%) manuscripts; instead these contributors have been listed as authors without fulfilling ICMJE criteria. Authorship violation was not more common in 42 manuscripts with some type of scientific misconduct (P=0.135). Large proportion of authors of the manuscripts submitted to Biochemia Medica do not fulfil ICMJE criteria. Violation of authorship criteria is not more common for manuscripts with some type of scientific misconduct.

De Materia Medica written by Pedanios Dioscorides (1 century CE) has shaped European and Mediterranean herbal medicine to a large extent. Despite its fundamental importance for modern medico-botanical traditions the content of this work has never been systematically assessed. We present a quantitative survey of the botanical drugs described in De Materia Medica (ex Matthioli, 1568) and identify overall therapeutic, diachronic and botanical patterns. The extracted data may serve as a baseline and help to better contextualize research on herbal drugs and phytotherapy. Therapeutic uses of herbal drugs were extracted through line-by-line reading of a digitized version of the treatise. For each plant usage mentioned in the text we recorded (I) the chapter number, (II) the putative botanical identity, (III) the plant part, (IV) the symptoms or disease, (V) the mode of administration, (VI) our biomedical interpretation of the ancient ailment or disease description as well as (VII) the organ- and symptom-defined category under which the use was filed. An introduction to Dioscorides' De Materia Medica and Matthioli's Renaissance commentary is followed by a description of the employed methodology. The results and discussion section introduces the generated database comprising 5314 unique therapeutic uses of 536 plant taxa and 924 herbal drugs. Separate subsections address salient patterns such as the frequent recommendation of Fabaceae seeds for dermatology, Apiaceae seeds as antidotes and Apiaceae exudates for neurology and psychosomatic disorders as well as the heavy reliance on subterranean parts as drugs. The therapeutic knowledge described in De Materia Medica (ex Matthioli, 1568) offers unique insights into classical Mediterranean epidemiology and herbal medicine. Drugs that lost importance over time as well as remedies used for diseases now controlled by preventive medicine and industrially produced drugs may be interesting starting points for research on herbal

The antiepileptic Materia Medica of Pediacus Dioscorides.

Eadie, M J

2004-09-01

Since it was written about the middle of the 1st Century AD, and up to comparatively recent times, the great Herbal, or Materia Medica, of Dioscorides provided medicine with its chief source of information about what were then considered therapeutic substances. The work contained data on various materials of botanical, biological and mineral origin which were claimed to provide benefit to sufferers from epilepsy, though often with no clear underlying rationale for their use. Some of these materials continued to be used as antiepileptic remedies over many centuries till they were finally recognised to be without useful effect in the disorder. The longest survivor amongst the Dioscoridean antiepileptic remedies was a rather esoteric one, viz. two stones taken from the belly of a young swallow during the rising phase of the moon and also whilst the swallow's parent birds were absent from the nest. The stones, or one of them, were worn against the skin of the seizure sufferer. The use of the swallow stones for epilepsy was recommended as late as in the writings of Thomas Willis (1675).

Phylogenetic relationships of Indian Citron (Citrus medica L.) with other important Citrus species have been inferred through sequence analyses of rbcL and matK gene region of chloroplast DNA. The study was based on 23 accessions of Citrus genotypes representing 15 taxa of Indian Citrus, collected from wild, semi-wild, and domesticated stocks. The phylogeny was inferred using the maximum parsimony (MP) and neighbor-joining (NJ) methods. Both MP and NJ trees separated all the 23 accessions of Citrus into five distinct clusters. The chloroplast DNA (cpDNA) analysis based on rbcL and matK sequence data carried out in Indian taxa of Citrus was useful in differentiating all the true species and species/varieties of probable hybrid origin in distinct clusters or groups. Sequence analysis based on rbcL and matK gene provided unambiguous identification and disposition of true species like C. maxima, C. medica, C. reticulata, and related hybrids/cultivars. The separation of C. maxima, C. medica, and C. reticulata in distinct clusters or sub-clusters supports their distinctiveness as the basic species of edible Citrus. However, the cpDNA sequence analysis of rbcL and matK gene could not find any clear cut differentiation between subgenera Citrus and Papeda as proposed in Swingle's system of classification.

The objective of this study was to evaluate the influence of irrigants on the antimicrobial potential of calcium hydroxide paste in dogs' teeth with apical periodontitis. Forty-eight premolar teeth of adult mongrel dogs had their root canals opened to the oral environment for 6 months. The root canals were prepared and treated with different irrigating solutions and intracanal medicaments, according to the following groups: 1) 2.5% sodium hypochlorite (NaOCl) + calcium hydroxide paste (CHP); 2) 2% chlorhexidine (CHX) + CHP; 3) vinegar + CHP; 4) vinegar + vinegar. In group 4, both the irrigating solution and intracanal medicament were vinegar, which was renewed every 7 days. Each sample was collected by using two paper points maintained in position for 1 min, and individually transported and immersed in 7 mL of Letheen broth (LB), followed by incubation at 37 degrees C for 48 h. Microbial growth was analyzed by two methods: turbidity of the culture medium and subculture on a specific nutrient broth (brain heart infusion). After 21 days, all experimental groups had microbial growth, however, in different percentages: group 1 - 30%; group 2 - 30%; group 3 - 40%; group 4 - 60%. All materials tested had antimicrobial potential; however, the influence of calcium hydroxide paste on the control of microorganisms must be remembered.

The evaluation of permeability in biopharmaceutics classification system of Chinese materia medica (CMMBCS) requires multicomponent as a whole in order to conduct research, even in the study of a specific component, should also be put in the multicomponent environment. Based on this principle, the high content components in Gegen Qinlian decoction were used as multicomponent environmental impact factors in the experiment, and the relevant parameters of intestinal permeability about puerarin were measured with using in situ single-pass intestinal perfusion model, to investigate and evaluate the intestinal permeability of puerarin with other high content components. The experimental results showed that different proportions of baicalin, glycyrrhizic acid and berberine had certain influence on intestinal permeability of puerarin, and glycyrrhizic acid could significantly inhibit the intestinal absorption of puerarin, moreover, high concentration of berberine could promote the absorption of puerarin. The research results indicated that the important research ideas of permeability evaluation in biopharmaceutics classification system of Chinese materia medica with fully considering the effects of other ingredients in multicomponent environment.

To compare the effects of Allium sativum oil and formocresol on the pulp tissue of the pulpotomized teeth. Twenty children were selected for this study. All children had a pair of non-vital primary molars. A sterile paper point was dipped in the root canals prior to the mortal pulpotomy. These paper points were collected in transfer media and immediately transported to the microbiological lab to be investigated microbiologically (for Streptococcus mutans and Lactobacillus acidophilus). Then the procedure of mortal pulpotomy was performed. After 2 weeks, the cotton pellets were removed and sterile paper points were dipped in the root canals for microbiological examination. Then comparison between the count of bacteria before and after treatment was conducted. Statistical analysis was performed using independent t-test and paired t-test at the significance level of α = 0.05. After application of both medicaments, there was a marked decrease in S. mutans and L. acidophilus counts. The difference between the mean of log values of the count before and after the application was highly significant for both medicaments (P < 0.05); however, better results were obtained when A. sativum oil was used. A. sativum oil had more powerful antimicrobial effects than formocresol on the bacteria of the infected root canals.

Long-term use of intracanal medicaments such as calcium hydroxide (CH) reduces the fracture resistance of dentin. The present study was undertaken to evaluate the fracture resistance of radicular dentin on long-term use of CH, chlorhexidine (CHX) with lycopene (LP). To compare the fracture resistance of radicular dentin when intracanal medicaments such as CH, CHX with LP were used for 1-week and 1-month time interval. Sixty single-rooted extracted human permanent premolars were collected, and complete instrumentation was done. Samples were divided into three groups based on intracanal medicament used. Group 1 - no medicament was placed (CON), group 2 - mixture of 1.5 g of CH and 1 ml of 2% CHX (CHCHX), group 3 - mixture of 1.5 g of CH, 1 ml of CHX and 1 ml of 5% LP solution (CHCHXLP). After storage period of each group for 1-week and 1-month, middle 8 mm root cylinder was sectioned and tested for fracture resistance. Results were analyzed using paired t-test. At 1-month time interval, there was a statistically significant difference in fracture resistance between CHCHX and CHCHXLP groups. Addition of LP has not decreased the fracture resistance of radicular dentin after 1-month.

Aucklandia lappa Decne was first recorded in the Sheng nong ben cao jing (Shennong's Classic of Materia Medica). Through the textual research of herbal literature, it was found that the costus root in the Sheng nong ben cao jing perhaps was not the plant of Aucklandia lappa Decne of Compositae, but the eaglewood or Lignum Aquilasria Resinatum based on the comprehensive judgment of shape, taste, nature, and function etc. In the Sheng nong ben cao jing, it only includes costus root without the title of eaglewood, and Tao Hongjing recorded both herbs together in his Ming yi bie lu (Supplementary Records of Celebrated Physicians), which became a foreshadow of misunderstanding of the later generations. Beginning from the Tang ben cao (Materia Medica of the Tang Dynasty), the costus root was considered as the plant of Auckiandia lappa Decne from the Compostae with its profound influence until now.

Ala-al-din abu Al-Hassan Ali ibn Abi-Hazm al-Qarshi al-Dimashqi, known as Ibn al-Nafis (1210-1288 AD), was a Muslim Syrian physician primarily famous for being the first to describe the pulmonary circulation of the blood. The most voluminous of his books is Alshamel fi Sana'at tebbi'at, which is a comprehensive medical encyclopedia. It comprised 300 volumes of notes, from which only 80 volumes are published. His writings are cataloged in many libraries around the world. The aim of this review article, as a tribute to Ibn al-Nafis, was to introduce his valuable but neglected encyclopedia of Materia Medica. Ibn al-Nafis' traditional approach in his "Alshamel fi Sana'at tebbi'at" book is studied in the present article. Alshamel fi Sana'at tebbi'at covers three branches of knowledge. The first category is devoted to theoretical traditional medicine. The second is in four sections where much of it is not available yet. The third category is on Materia Medica covering the aspect of Unani medicine, from which only 28 volumes of the comprehensive book on the traditional medicine have been found so far. The latter, introduces mono-ingredient medications in alphabetical order. Each chapter, in several parts, is dedicated to the botanical characteristics and nature of each mono-ingredient medication. In addition, this book explains traditional pharmacokinetic of every single medication for each human body organs. Based on pharmaco-mechanistic perspective on Alshamel fi Sana'at tebbi'at, it could be considered as the main reference book on traditional medicine and pharmacy, worthy of revival.

Toxicity of Chinese materia medica (CMM) is an important part of Chinese herbal nature theory. In clinical application, the dosage, time limitation and compatibility of CMM is mainly determined by toxicity. At present, there is no uniform toxicity classification standard for the evaluation of Chinese herbal toxicity. Therefore, it is significant to research toxicity classification of CMM. The current situation of toxicity classification of CMM is reviewed in this paper, and proposed research thoughts are as follows: the measurement of toxicity parameters, the confirmation of poisoning target organs, the investigation on toxic mechanism by serum pharmacology and toxicokinetics, the comprehensive evaluation on toxicity based on quantitative theory.

A cost comparison study was made of Excerpta Medica's abstracting journals, based upon actual costs to a library. Unit costs were determined for six sections of EM as compared with six corresponding abstract journals. On average, EM sections were found to be 138% more costly than corresponding abstract journals. The effects of splitting of EM journal titles were also analyzed. This practice increases the price of a total subscription to EM and makes comprehensive information retrieval more difficult. A survey of medical school librarians as users of EM points to dissatisfaction with its increasing price, particularly when it results from title splitting. PMID:843653

A rapid and sensitive dot-blot hybridization assay using in vitro-transcribed digoxigenin-labelled RNA probes (riboprobes) was developed aiming at detection of citrus exocortis viroid (CEVd) in crude sap of infected Citrus medica plants. The protocol includes a very quick and simple preparation of RNA extracts from samples using a denaturation step with formaldehyde. From our results, the employment of this step is highly recommended because the hybridization signals in formaldehyde-denatured samples were significantly stronger when compared with that of extracts without formaldehyde treatment. The assay was found to be sensitive enough to detect 0.1 ng of purified CEVd RNA and was able to detect viroid in 0.2 mg of symptomatic Citrus medica leaves. The use of riboprobes also allowed hybridization under high temperature conditions, avoiding non-specific background.

Tumor-associated macrophages (TAMs) play a key role in all stages of tumorigenesis and tumor progression. TAMs secrete different kinds of cytokines, chemokines, and enzymes to affect the progression, metastasis, and resistance to therapy depending on their state of reprogramming. Therapeutic benefit in targeting TAMs suggests that macrophages are attractive targets for cancer treatment. Chinese materia medica (CMM) is an important approach for treating cancer in China and in the Asian region. According to the theory of Chinese medicine (CM) and its practice, some prescriptions of CM regulate the body's internal environment possibly including the remodeling the tumor microenvironment (TME). Here we briefly summarize the pivotal effects of TAMs in shaping the TME and promoting tumorigenesis, invasion, metastasis and immunosuppression. Furthermore, we illustrate the effects and mechanisms of CMM targeting TAMs in antitumor therapy. Finally, we reveal the CMM's dual-regulatory and multi-targeting functions on regulating TAMs, and hopefully, provide the theoretical basis for CMM clinical practice related to cancer therapy.

The role of contact allergy in rosacea has rarely been investigated. In this retrospective study, 361 out of 76,697 patients tested and documented by the Information Network of Departments of Dermatology between 1995 and 2002 had rosacea. Patch tests included standard series and constituents of cosmetics and topical medicaments. 118/361 had additionally been patch tested with their own cosmetics/medicaments. Positive reactions occurred to nickel (II) sulfate in 9.3%, fragrance mix in 8.8%, thimerosal in 6.9%, Myroxylon pereirae resin in 5.9%, potassium dichromate in 4.6% and propolis in 2.8%. Whereas rosacea patients had a significantly higher risk of contact allergy to propolis compared to the remaining patients, in an age- and sex-adjusted analysis, contact allergy to nickel was significantly less frequent in this group. For Lyral, the risk was elevated, albeit not significantly. Only 2/329 patients were positive to neomycin sulfate and 1/100 to gentamicin sulfate, among the panel of (topical) antibiotics tested. Among 118 patients tested with their own products, 3 were tested to metronidazole, 1 reacting positively. Irritant or doubtful patch test reactions were provoked by various substances (vehicles, oxidants and preservatives of various creams), which might also be clinically important, considering the heightened sensitivity of rosaceous skin.

A simple and accurate scoring system to predict risk of transfusion for patients undergoing cardiac surgery is lacking. We identified independent risk factors associated with transfusion by performing univariate analysis, followed by logistic regression. We then simplified the score to an integer-based system and tested it using the area under the receiver operator characteristic (AUC) statistic with a Hosmer-Lemeshow goodness-of-fit test. Finally, the scoring system was applied to the external validation dataset and the same statistical methods applied to test the accuracy of the ACTA-PORT score. Several factors were independently associated with risk of transfusion, including age, sex, body surface area, logistic EuroSCORE, preoperative haemoglobin and creatinine, and type of surgery. In our primary dataset, the score accurately predicted risk of perioperative transfusion in cardiac surgery patients with an AUC of 0.76. The external validation confirmed accuracy of the scoring method with an AUC of 0.84 and good agreement across all scores, with a minor tendency to under-estimate transfusion risk in very high-risk patients. The ACTA-PORT score is a reliable, validated tool for predicting risk of transfusion for patients undergoing cardiac surgery. This and other scores can be used in research studies for risk adjustment when assessing outcomes, and might also be incorporated into a Patient Blood Management programme. © The Author 2017.

To evaluate and compare the effect of antibacterial intracanal medicaments on inter-appointment flare-up in diabetic patients. Fifty diabetic patients requiring root canal treatment were assigned into groups I, II, and III. In group I, no intracanal medicament was placed. In groups II and III, calcium hydroxide and triple antibiotic pastes were placed as intracanal medicaments, respectively. Patients were instructed to record their pain on days 1, 2, 3, 7, and 14. Inter-appointment flare-up was evaluated using verbal rating scale (VRS). Overall incidence of inter-appointment flare-up among diabetic patients was found to be 16%. In group I, 50% of the patients and in group II, 15% of the patients developed inter-appointment flare-up. However, no patients in group III developed inter-appointment flare-up. The comparison of these results was found to be statistically significant (P = 0.002; χ(2) = 12.426). However, with respect to intergroup comparison, only the difference between groups I and III was found to be statistically significant (P = 0.002; χ(2) = 12.00). Calcium hydroxide and triple antibiotic paste are effective for managing inter-appointment flare-ups in diabetic patients.

Near-infrared chemical imaging (NIR-CI) is an emerging technology that combines traditional near-infrared spectroscopy with chemical imaging. Therefore, NIR-CI can extract spectral information from pharmaceutical products and simultaneously visualize the spatial distribution of chemical components. The rapid and non-destructive features of NIR-CI make it an attractive process analytical technology (PAT) for identifying and monitoring critical control parameters during the pharmaceutical manufacturing process. This review mainly focuses on the pharmaceutical applications of NIR-CI in each unit operation during the manufacturing processes, from the Western solid dosage forms to the Chinese materia medica preparations. Finally, future applications of chemical imaging in the pharmaceutical industry are discussed. Copyright © 2015 John Wiley & Sons, Ltd.

2014-01-01

Aim: To evaluate and compare the effect of antibacterial intracanal medicaments on inter-appointment flare-up in diabetic patients. Materials and Methods: Fifty diabetic patients requiring root canal treatment were assigned into groups I, II, and III. In group I, no intracanal medicament was placed. In groups II and III, calcium hydroxide and triple antibiotic pastes were placed as intracanal medicaments, respectively. Patients were instructed to record their pain on days 1, 2, 3, 7, and 14. Inter-appointment flare-up was evaluated using verbal rating scale (VRS). Results: Overall incidence of inter-appointment flare-up among diabetic patients was found to be 16%. In group I, 50% of the patients and in group II, 15% of the patients developed inter-appointment flare-up. However, no patients in group III developed inter-appointment flare-up. The comparison of these results was found to be statistically significant (P = 0.002; χ2 = 12.426). However, with respect to intergroup comparison, only the difference between groups I and III was found to be statistically significant (P = 0.002; χ2 = 12.00). Conclusions: Calcium hydroxide and triple antibiotic paste are effective for managing inter-appointment flare-ups in diabetic patients. Triple antibiotic paste is more effective than calcium hydroxide in preventing the occurrence of flare-up in diabetic patients. PMID:24944440

2014-03-01

Many important drugs in the Chinese materia medica (CMM) are known to be toxic, and it has long been recognized in classical Chinese medical theory that toxicity can arise directly from the components of a single CMM or may be induced by an interaction between combined CMM. Traditional Chinese Medicine presents a unique set of pharmaceutical theories that include particular methods for processing, combining and decocting, and these techniques contribute to reducing toxicity as well as enhancing efficacy. The current classification of toxic CMM drugs, traditional methods for processing toxic CMM and the prohibited use of certain combinations, is based on traditional experience and ancient texts and monographs, but accumulating evidence increasingly supports their use to eliminate or reduce toxicity. Modern methods are now being used to evaluate the safety of CMM; however, a new system for describing the toxicity of Chinese herbal medicines may need to be established to take into account those herbs whose toxicity is delayed or otherwise hidden, and which have not been incorporated into the traditional classification. This review explains the existing classification and justifies it where appropriate, using experimental results often originally published in Chinese and previously not available outside China.

Chinese marine materia medica (CMMM) is a vital part of traditional Chinese medicine (TCM). Compared with terrestrial TCM, CMMM, derived from specific marine habitats, possesses peculiar chemical components with unique structures reflecting as potent pharmacological activities, distinct drug properties and functions. Nowadays, CMMM appears to be especially effective in treating such difficult diseases as cancers, diabetes, cardio-cerebrovascular diseases, immunodeficiency diseases and senile dementia, and therefore has become an important medicinal resource for the research and development of new drugs. In recent years, such development has attracted wide attention in the field of medicine. In this study, the CMMM resources in China were systematically investigated and evaluated. It was found that the historic experiences of Chinese people using CMMM have continuously accumulated over a period of more than 3600 years, and that the achievements of the research on modern CMMM are especially outstanding. By June 2015, 725 kinds of CMMMs from Chinese coastal sea areas have been identified and recorded, covering 1552 organisms and minerals. More than 3100 traditional prescriptions containing CMMMs have been imparted and inherited. However, the number of CMMMs is less than the 8188 terrestrial TCMs, from more than 12,100 medicinal terrestrial plants, animals and minerals. In the future, the research and development of CMMM should focus on the channel entries (TCM drug properties), compatibility, effective ingredients, acting mechanisms, drug metabolism and quality standard. This study reveals the high potential of CMMM development. PMID:26950133

Sun, Xing; Chen, Lijue; Zeng, Fanbo

2011-01-01

The objective of this paper was to investigate the effects of a Chinese Materia Medica variant -Fubao Danggui Jiao (FDJ)-on experimental endometriosis. An endometriosis model was created by virtue of auto-transplantation of endometrial tissue onto rats' abdominal walls. The implants were allowed to grow for 30 days until the successful completion of the model. After that, forty endometriotic rats were randomly divided into four study groups and given different treatments: (1) negative control group (water, 2ml/kg, per os); (2) FDJ-A group (FDJ, 2ml/kg, per os); (3) FDJ-B group (FDJ, 4ml/kg, per os); (4) Danazol group (70mg/kg, per os). After 30 days with treatments, the volumes of endometriotic implants in each rat were measured. The implants and normal uterine horns were removed for routine histological examination. FDJ caused significant decreases in volumes of the surviving endometriotic implants, with two different doses having statistically equivalent effects. Upon histological examination, FDJ was observed to cause regression of epithelium and stroma of endometriotic implants. FDJ had revealed promising therapeutic effects on endometriosis.

To establish the HPLC fingerprint of flavonoids of the six clinical frequently used Chinese materia medica for regulating Qi flow,such as Citri grandis, C. grands, Citri Reticulatae Pericarpium, Citri Reticulatae Pericarpium Viride, Aurantii Fructus, and Aurantii Fructus Immaturus from Citrus, and analysis differences in the fingerprints to provide scientific basis for profile-effect research and clinical reasonable use. HPLC was performed on a C18 column with methanol-water (with acetic acid), to establish HPLC fingerprints of the six kinds of medicinal herbs on the same chromatograph condition. The six frequently used Chinese materia medica were divided into naringin type and hesperidin type according to the method of phytochemotaxonomy. Based on the retention time of chromatograph peaks, C. grandis and C. grands had fifteen common peaks; Citri Reticulatae Pericarpium, Citri Reticulatae Pericarpium Viride, Aurantii Fructus and Aurantii Fructus Immaturus had ten common peaks. All herbs had five common peaks. Compared with mutual model, the holistic similarity of chromatograms of C. grandis and C. grands was in the range of 0.9285 - 0.9962. The degree of similarity was high. For Citri Reticulatae Pericarpium, Citri Reticulatae Pericarpium Viride and Aurantii Fructus Immaturus, it was in the range of 0.9221 - 0.9973 and high. But the similarity of Aurantii Fructus was only in 0.4547 - 0.7733 with the mutual model. The established fingerprints of flavonoids of the six common traditional Chinese medicines can be used to compare the differences intuitively. Meanwhile, the peak height and peak areas of characteristic peaks are different remarkably, but whether it is connected with the different function of regulating Qi flow of the six medical materials in clinical use, is still needed to be studied.

Extraction of polysaccharides from Gynura medica (GMPs) was optimized by response surface methodology (RSM). A central composition design including three parameters, namely extraction temperature (X₁), ratio of water to raw material (X₂) and extraction time (X₃), was used. The best conditions were extraction temperature of 91.7 °C, extraction time of 4.06 h and ratio of water to raw material of 29.1 mL/g. Under the optimized conditions, the yield of GMPs was 5.56%, which was similar to the predicted polysaccharides yield of 5.66%. A fraction named GMP-1 was obtained after isolation and purification by DEAE-52 and Sephadex G-100 gel chromatography, respectively. GMP-1, with a molecular weight of 401 kDa, mainly consisted of galacturonic acid (GalA), xylose (Xyl), glucose (Glu). Infrared spectroscopy was used to characterize the major functional groups of GMP-1 and the results indicated that it was an acidic polysaccharide. The antioxidant and α-glucosidase inhibitory activities of GMPs and GMP-1 were determined in vitro. The results indicated that GMPs and GMP-1 show potential for use in functional foods or medicines.

Authentication of Chinese Materia Medica (CMM) decoction dregs is important for ensuring the efficacy and safety of CMM when they are used in decoction. If someone got worse or poisoned after taking a decoction while the formula is appropriate, the authentication of CMM dregs is the effective method to explore the reasons. Therefore, a systematic study on the authentication of CMM dregs was carried out. In this study, two pairs of easily confused CMM dregs, Fenge (Puerariae Thomsonii Radix) and Shanyao (Dioscoreae Rhizoma), Dihuang (Rehmanniae Radix) and Huangjing (Polygonati Rhizoma), which mostly comprise storage tissues, were investigated by comparing the morphological and microscopic characteristics. Fenge and Shanyao contain abundant starch granules. After decoction their dregs were hard, nonstarchy and horn-like. Fully gelatinized starch granules were found in the powder of Fenge dregs while incompletely gelatinized starch granules were occasionally found in the Shanyao dregs. In contrast, Dihuang and Huangjing contain water-soluble sugars. After decoction, their dregs were hard and brittle. Their parenchymatous cells were shrunken and unknown crystals were found under microscope. Hence, the morphological and microscopic characteristics of CMM before and after decoction were different, and different changes in the CMM dregs can be illustrated by the different nature of their ergastic substance. These differences could be used to authenticate CMM dregs. Copyright © 2011 Wiley Periodicals, Inc.

This article presents the results of a study of the medicinal uses of natural substances in medieval and Ottoman al-Sham (the Levant). It involved a meticulous survey of a wide range of historical sources spanning approximately 1100 years and including medical and pharmacological literature, travelogues, geographical and agricultural literature, dictionaries, archives, the Genizah and other medieval sources. Our main goal was to arrive at a reconstruction of the unwritten materia medica of the medieval and Ottoman Levant. Of the many and varied medicinal substances on which we were able to extract information, we were able to identify 286. These are presented according to the following classification: 234 species of plants (81.8%); 27 species of animals (9.5%); 15 kinds of minerals (5.2%) and 10 substances of other or mixed origin (3.5%). Analysis of the data showed that the region under study served as the geographic origin of the majority of the substances, only a minority of the materials was imported. The main reason for this is the geographic location of the Levant as a junction between three continents, as a cultural meeting point and as trade center. Finally, our data revealed that the al-Sham region was an independent source of production and marketing of medicinal substances during the medieval and Ottoman periods.

Chinese vegetative materia medica in a venereological treatise by Jean Astruc from 1740.

Historical medical sources can be still queried for forgotten cures and remedies. Traditional Chinese medicine has dealt with lues venerea (syphilis) since the Five Dynasties period (10th century). Chinese indigenous materia medica and remedies recorded, studied or imported by the Europeans can reveal known or quite unknown medicinal plants. The studied Jean Astruc's work is a published ethnopharmacological survey carried out in Beijing in the 1730s and it deserves a modern interpretation. This is the first proposal to identify historical Chinese medicinal plants listed in a scarcely known medical treatise De Morbis venereis… ('On venereal diseases…') by Jean Astruc from 1740. I searched for the current uses and position of the taxonomically identified herbal stock in both traditional Chinese and official medical knowledge, with special attention to syphilis. Chinese names of drugs and their botanical identities (originally expressed by means of pre-Linnaean polynomials, and now interpreted as accepted binomials) were independently cross-checked with younger till most recent taxonomical and ethnopharmacological sources. Plants and drugs identified this way were queried for their modern applications in traditional Chinese and official medicine with special attention to sexually transmitted diseases (STD) and other uses which are similar to the 18th-century understanding of venereology. For 24 items of medicinal stock, 34 medicinal plants have been identified or suspected: Acacia catechu, Achyranthes bidentata, Akebia quinata, Angelica dahurica, A. sinensis, Aquilaria sinensis, Aralia cordata, Aristolochia fangchi, Chaenomeles sinensis, Ch. speciosa, Clematis vitalba, Coix lacryma-jobi, Commiphora myrrha, Cydonia oblonga, Daemonorops draco, D. jenkinsiana, Dictamnus dasycarpus, Dryobalanops sumatrensis, Forsythia suspensa, Glycyrrhiza uralensis, Lonicera confusa, L. hypoglauca, L. japonica, Ligusticum striatum (=L. chuanxiong), Piper kadsura, Pterocarpus

The Seongho School centered its studies mainly on classical Chinese texts of the Han (206 BC－AD 220) and pre-Han (?－221 BC) (xian-qin lianghan, ) periods rather than those of the Tang and Song dynasties (618-1279). gu xue scholarship emerged during the Ming dynasty era (1368 －1644) as an alternative to the scholarly trends of the Song dynasty, which were dependent on Zhu Xi's (, 1130－1200) Neo-Confucianism and its interpretation of Han and pre-Han classical Chinese texts. This scholarly trend influenced Korean and Japanese literature, philosophy, and even medicine from the seventeenth through the nineteenth centuries. Focusing on Korean scholarship, we find a great deal of research regarding the influence of gu xue on Korean classical Chinese literature and Confucian philosophy in the late Joseon period; however, no study has examined how this style of scholarship influenced the field of medicine during the same period. This study will investigate how the intellectuals of the Seongho School, who did the most to develop gu xue among Joseon intellectuals, were influenced by this style of scholarship in their study of the materia medica. Jeong Yak-yong (1762－1836), the representative intellectual of the Seongho School, did not focus on complicated metaphysical medical theories, such as the Yin-Yang and Five Elements theory (yin yang wu xing shui, ) or the Five Movements and Six Atmospheres theory (wu yun liu qi shui, ). Instead, his interests lay in the exact diagnoses of diseases and meticulous herbal prescriptions which formed an essential part of the Treatise on Exogenous Febrile Disease (Shang han lun, ) written by Zhang Zhungjing (, 150－219) in the Han dynasty. The Treatise was compatible with the scholarly purpose of gu xue in that they both

Abstract Historians of indigenous medicine in colonial India have looked more closely at the changes, reinventions and reformulations of institutions of Ayurveda and Unani than at the cognitive content of the drugs themselves. The few historians who have examined the changing content of indigenous medicines have conceptualised the creation of materia medica of Indian drugs through two tropes: one of circulation (of specific drugs) through epistemological and geographic boundaries and the second, of marginalisation of certain other drugs either through a lack of textual legitimacy or the lack of the newly discovered ‘active principles’ within each drug. While these approaches have been useful, there is a case to be made for understanding the creation of formularies of Indian drugs in 19th and 20th centuries through the prism of medical praxis in India.

In humans, more than 200 missense mutations have been identified in the ACTA1 gene. The exact molecular mechanisms by which, these particular mutations become toxic and lead to muscle weakness and myopathies remain obscure. To address this, here, we performed a molecular dynamics simulation, and we used a broad range of biophysical assays to determine how the lethal and myopathy-related H40Y amino acid substitution in actin affects the structure, stability, and function of this protein. Interestingly, our results showed that H40Y severely disrupts the DNase I-binding-loop structure and actin filaments. In addition, we observed that normal and mutant actin monomersmore » are likely to form distinctive homopolymers, with mutant filaments being very stiff, and not supporting proper myosin binding. Lastly, these phenomena underlie the toxicity of H40Y and may be considered as important triggering factors for the contractile dysfunction, muscle weakness and disease phenotype seen in patients.« less

A complex extraction system with the use of cloud-point extraction technique (CPE) was developed for sequential isolation of basic and acidic/neutral medicaments from human plasma/serum, screened by HPLC/DAD method. Eight model drugs (paracetamol, promazine, chlorpromazine, amitriptyline, salicyclic acid, opipramol, alprazolam and carbamazepine) were chosen for the study of optimal CPE conditions. The CPE technique consists in partition of an aqueous sample with addition of a surfactant into two phases: micelle-rich phase with the isolated compounds and water phase containing a surfactant below the critical micellar concentration, mainly under influence of temperature change. The proposed extraction system consists of two chief steps: isolation of basic compounds (from pH 12) and then isolation of acidic/neutral compounds (from pH 6) using surfactant Triton X-114 as the extraction medium. Extraction recovery varied from 25.2 to 107.9% with intra-day and inter-day precision (RSD %) ranged 0.88-1087 and 5.32-17.96, respectively. The limits of detection for the studied medicaments at λ 254nm corresponded to therapeutic or low toxic plasma concentration levels. Usefulness of the proposed CPE-HPLC/DAD method for toxicological drug screening was tested via its application to analysis of two serum samples taken from patients suspected of drug overdosing.

To evaluate the efficacy of 3% sodium hypochlorite (NaOCl), 17% ethylenediaminetetraacetic acid (EDTA), calcium hydroxide [Ca (OH)2], and 2% chlorhexidine in various combinations on Candida albicans in root canals for 48 h and 10 days. In this in vitro study, 95 extracted teeth were instrumented. MTCC 183 strain of C. albicans was introduced into the root canals and after 7 days, the average value of colony forming units (CFUs)/ml was determined in all the roots. Then the teeth were randomly divided into three groups: Group I (n = 15) was the control group and only saline was added to it. In group II (n = 40), 3% NaOCl was used as the irrigant and in group III (n = 40), 3% NaOCl and 17% EDTA were used as irrigants. Groups II and III were further divided into two subgroups (A and B) having 20 teeth each. After irrigation, Ca (OH)2 was placed in subgroup A and 2% chlorhexidine digluconate (CHX) solution in subgroup B of both groups as intracanal medicament. After 48 h, the CFUs/ml was determined in 45 teeth (5 from the control group and 10 from each subgroup). After 10 days, the CFUs/ml was determined in the remaining 50 teeth (10 from the control group and 10 from each subgroup). For statistical analysis, Statistical Package for Social Sciences (SPSS version 15, Chicago IL, USA) was used. A decrease in CFUs/ml of C. albicans was noted in all subgroups at 48 h, but the combination of NaOCl, EDTA, and CHX (group IIIB) was the most effective showing value of 0.095 × 10(5) CFUs/ml. On the 10(th) day, the CFUs/ml of C. albicans was further decreased in all subgroups; but again, subgroup IIIB was the most effective showing a value of 0.025 × 10(5) CFUs/ml. There was statistically significant difference in CFUs/ml of C. albicans at 48 h and on 10(th) day in all study groups. The antimicrobial activity of irrigant and intracanal medicament has a positive role in controlling the growth of C. albicans.

XXII European Congress of Medical Informatics (MIe 2009) took place in Sarajevo from August 30th to September 2nd 2009. Assessment of quality of papers presented at MIe 2009 was a process of observation, measurement, comparison and evaluation of the quality of orally presented papers. For this study, and for the first time since EFMI founding (1976) and MIE congresses, the authors introduced a specially created quality assessment form with five relevant paper quality variables (methodological approach, international influence, scientific content, language quality, technical features) which the first author of this article used in peer-review process of papers submitted for publication in the journal Acta Informatica Medica (as Editor-in-Chief for last 18 years). The survey was conducted on the principle of random sampling of participants of MIE 2009 Conference in Sarajevo, where specially trained interviewers (final year students of medicine and engineering at the University of Sarajevo) interviewed 33 session's chairs and 110 participants/listeners of MIE 2009 paper presentations in 33 sessions (of total 40). Data was collected, entered into a specially created database, analyzed and presented. From the total of 150 oral presentations at the MIE 2009, 110 oral presentations were graded by both chairs and participants/ listeners. Grading results were compared and we found that in 60% of cases (66 papers) session chairs gave higher ratings than other participants of the congress. The highest rating was 10, and the lowest 3. Only 3 of the papers received all four grades 10 from the session chairs. The most common grade given by chairs of the session was 8 (26.36%), followed by 7 (20%), 9 (19.32%), 6 (13.18%), 10 and 5 (7.50%), 4 (5%) and 3 (1.14%). Significant differences in quality assessment of papers done by chairs and those done by other participants/listeners are observed. This work should demonstrate the importance of introducing universal (uniform) scale for

To investigate the clinical manifestations, complications and treatment of medicament-like dermatitis due to trichloroethylene (TCE), so as to provide basis for studying its etiology and mechanism. Fifty patients with dermatitis due to TCE from 1997 to 2000 were analysed retrospectively. The occurrence of the dermatitis was not parallel to TCE exposure levels, without significant dose-effect relationship. This disease could be caused by both inhalation and skin exposure. The latency period of TCE dermatitis ranged from 5 to 66 days, and the average was 31.5 d (Medium). The major clinical manifestations included skin lesions, fever, superficial lymph node swelling and liver dysfunction. Infection was the major complication. Glucocorticoid was effective for treatment of this disease. The clinical manifestations due to TCE exposure were similar to dermatitis medicamentosa. The major clinical types of TCE dermatitis included exfoliative dermatitis and erythema multiforme. The dermatitis is considered to be mediated by delayed-type (IV) hypersensitivity. The key factors to treat this disease successfully included the use of glucocorticoid in time with sufficient dose and full course, professional skin care, active treatment to protect the liver and to avoid infection.

The governments and organizations responsible for scientific policies try to encourage equality of gender, among their priorities that of obtaining equal participation and full integration of women in all aspects of the scientific profession. The study analyzes the scientific production of women in the areas of Psychiatry by means of the bibliometric study of the papers published in ACTAS ESPANOLAS DE PSIQUIATRIA. A total of 458 papers published from 1999- 2006 period were downloaded from the Science Citation Index-Expanded database, these including original research papers, review articles and clinical cases. A bibliometric study broken down by gender was carried out to determine the existence or inequalities between men and women regarding scientific productivity, type of document, order of author signatures, on the institutional and geographical level. The papers were published by 1,194 different authors. The gender of 977 authors was identified, 587 (60.08%) men and 390 (39.92%) women. The percentage of women authorship has risen from 29.92% in 1999 to 38.86% in 2006. A total of 42.92% of authors having one published article were women, while (those with more than nine articles) only accounted for 33%. Bibliometric studies on scientific activity provide essential information to promote gender equality. An annual increase over 1% in the number of female authors in the journal has been observed, which if it continues will lead to a parity in coming years.

Citri Fructus (CF), the mature fruit of Citrus wilsonii Tanaka (CWT) or Citrus medica L. (CML), is an important citrus by-product with health promoting and nutritive properties. The present study compares the chemical and biological differences of CWT and CML. Thin layer chromatography and high performance liquid chromatography, coupled with quadrupole time-of-flight tandem mass spectrometry techniques, were employed to compare the chemical profiles of CWT and CML. A total of 25 compounds were identified and the results indicated that there were significant differences in chemical composition between the two CF species. The quantitative results obtained by HPLC coupled with diode array detector method demonstrated that naringin was present in the highest amounts in CWT, whilst nomilin was the most dominant constituent in CML. It was also found that CWT had significantly higher free radical-scavenging activity than CML. Copyright © 2014 Elsevier Ltd. All rights reserved.

During the period of the Republic of China, researches of experiments on Chinese materia medica developed extensively with the scientific process of Chinese medicine. Although the technology standard was relatively low and the reference value, limited. The experiences, positive or negative, obtained at that time still has reference significance to today's Chinese medicine scientific research. The notion that traditional Chinese medical and scientific research be conducted under the guidance of TCM theory; valuable experience contained in the ancient literature of traditional Chinese medicine be collected; and the transformation capacity of scientific research be elevated, has been accepted by modern TCM professionals. If you go back to the history, it can be seen that this notion was summarized through repeated practice during the critical moment of traditional Chinese medicine, which should be emphasized and its understanding deepened at any time.

Medicinal diets have a history of more than 2000 years. Locally referred to as yaoshan (Chinese: ), a medicinal diet is understood in China as a dietary product that combines herbs and food with the purpose of preventing and treating diseases or improving health under the guidance of traditional Chinese medicine theory. Medicinal diets are used in Chinese people's daily life and in specialized restaurants. Hundreds of Chinese materia medica (CMM) are used in medicinal diets; however, a comprehensive evaluation of medicinal diets is lacking. This is an exploratory study that aims to identify the CMM that are most frequently used in medicinal diets and to provide an updated view of the current situation of medicinal diets in China. A field study of 1221 people in 32 Chinese provinces was conducted over a period of approximately 6 months and included various types of interviews as well as a written questionnaire. Two approaches were used to analyse the data collected in the survey: (1) estimating the frequency of CMM consumed in daily diets; and (2) collecting CMM used in medicinal diet restaurants. Complementary information on the selected CMM was obtained from relevant databases, including PubMed, Google Scholar, Baidu Scholar, CNKI, and Web of Science. Ten CMM were reported as commonly used by more than 50% of the participants. Among these 10 species, most medicinally used parts were seeds and fruits. Pharmacological data from the literature revealed that these species are associated with a wide spectrum of biological properties, including antitumour (80%), antioxidant (50%), anti-diabetic (40%), antilipemic (40%), anti-aging (40%), antimicrobial (40%) and cardioprotective (40%) activities. Our survey shows that most medicinal diet restaurants are located in the eastern part of China, with the greatest numbers being found in Beijing and Guangzhou. Only Dioscoreae Rhizoma, Lycii Fructus, Chrysanthemi Flos and Longan Arillus were frequently consumed both in daily

A model for DNA computing using the recombination behavior of DNA molecules, known as a sticker system, was introduced by by L. Kari, G. Paun, G. Rozenberg, A. Salomaa, and S. Yu in the paper entitled DNA computing, sticker systems and universality from the journal of Acta Informatica vol. 35, pp. 401-420 in the year 1998. A sticker system uses the Watson-Crick complementary feature of DNA molecules: starting from the incomplete double stranded sequences, and iteratively using sticking operations until a complete double stranded sequence is obtained. It is known that sticker systems with finite sets of axioms and sticker rules generate only regular languages. Hence, different types of restrictions have been considered to increase the computational power of sticker systems. Recently, a variant of restricted sticker systems, called probabilistic sticker systems, has been introduced [4]. In this variant, the probabilities are initially associated with the axioms, and the probability of a generated string is computed by multiplying the probabilities of all occurrences of the initial strings in the computation of the string. Strings for the language are selected according to some probabilistic requirements. In this paper, we study fundamental properties of probabilistic simple sticker systems. We prove that the probabilistic enhancement increases the computational power of simple sticker systems.

Health food containing Chinese materia medica (CMM) conforms to the development demands of the age of big health and the theory of preventive treatment. In the view of health care and improvement of resisting diseases, it plays an important role in the market. It is very necessary to have further study and discussion on health food containing CMM. First of all, by comparing, analyzing and summarizing, the health food containing CMM could be defined as the health food which is qualified in security and functionality evaluation, with the traditional Chinese medicines(TCM) within TCM standards as the main raw materials, and the formulation-composition is based on the theory of TCM. It is characterized by higher safety than medicines, stronger biological activities than common food, multiple forms, abundant raw materials and integrated supervision and management. Secondly, we discussed the research and development (R&D) strategies and rules of health food containing CMM, pointing out that the core tasks of R&D include the investigation of formula, technology and the standards of quality. The fundamental principles of declaration and production include scientificity, rationality, reality and uniformity. Three key requirements (security, functionality and controllability) in the review as well as the process management of R&D and the key-points of risks control were summarized in this paper. Finally, the dynamic trends of policies and regulations related to health food containing CMM were analyzed in the view of registration, recording, raw materials and functions, and then related suggestions were proposed. Therefore, this article will be helpful in overall understanding the health food containing CMM and play a guiding role for its research and development.

Fifty-five subjects aged 17-60 years with teeth diagnosed to have apical periodontitis. Two-visit conventional root canal treatment of seventy teeth. The teeth were divided by randomization (balloting) into two groups: control group and experimental group, each with thirty-five teeth treated with calcium hydroxide mixed with normal saline or with 0.2% chlorhexidine digluconate as intracanal medicament respectively. Incidence of postoperative pain was assessed using the universal pain assessment tool and whether or not analgesic was taken. Incidence of post-operative pain. Postoperative pain occurred only at 1-day and 1-week reviews. In the control group, the overall incidence of pain was the same at both review periods (5.7%), while the experimental group showed a slight decrease in incidence between 1-day (17.2%) and 1-week (11.4%) reviews. Incidence of flare-ups was more in the experimental group (11.4%) than in the control group (5.7%). No significant statistical differences between the two groups were observed (p > 0.05). The incidence of postoperative pain was lower in the normal saline treatment group, but the difference was not statistically significant.

We report an eco-friendly method for the synthesis of copper nanoparticles (CuNPs) using Citron juice (Citrus medica Linn.), which is nontoxic and cheap. The biogenic copper nanoparticles were characterized by UV-Vis spectrophotometer showing a typical resonance (SPR) at about 631 nm which is specific for CuNPs. Nanoparticles tracking analysis by NanoSight-LM20 showed the particles in the range of 10-60 nm with the concentration of 2.18 × 10(8) particles per ml. X-ray diffraction revealed the FCC nature of nanoparticles with an average size of 20 nm. The antimicrobial activity of CuNPs was determined by Kirby-Bauer disk diffusion method against some selected species of bacteria and plant pathogenic fungi. It was reported that the synthesized CuNPs demonstrated a significant inhibitory activity against Escherichia coli followed by Klebsiella pneumoniae, Pseudomonas aeruginosa, Propionibacterium acnes and Salmonella typhi. Among the plant pathogenic fungi tested, Fusarium culmorum was found to be most sensitive followed by F. oxysporum and F. graminearum. The novelty of this work is that for the first time citron juice was used for the synthesis of CuNPs.

The activity of most deoxyribonuclease enzymes can be monitored by measuring the change in absorbance at 260 nm which accompanies the breakdown of the double-stranded structure of native DNA. An automated method for determining deoxyribonuclease activity, based on such an absorbance change, which can overcome problems of inhibition arising from the presence of inorganic cations, is described. Variations in inorganic cation concentration is a particular problem when measuring the activity of chromatographic fractions eluted via a salt gradient. A comparison is made between the automated and a manual method for the assay of deoxyribonuclease active constituents, of the medicament ‘Varidase’, eluted from a Cellex-D (Bio-Rad Laboratories Ltd) anionic exchange resin using a 0.05-1.0 M sodium chloride gradient.

On the 40th anniversary of the edition of Actas Urológicas Españolas, we assess the articles on history to determine the proportion represented, analysing the study subjects and their relevance, getting to know the authors, the main study centres and the interest that the studies offer for understanding the specialty. We extracted as many subjects of historic content from the journal as were published between January 1976 and December 2016. There were 103 historical studies representing 3% of the total number of articles, with a mean of 2.57 articles published annually, written by 127 separate urologists. As first author, there were 59 articles, and as coauthors, there were 68. The main activity came from 21 of the main university hospitals in Spain, and 43 of the articles were personal articles signed by a single individual. Their content mainly covers the facts of Spanish urology from the Renaissance to the 20th century, with special emphasis on the profile of Spanish specialists. Data on 22 of these specialists are provided in 37 articles. The evolution of diagnostic and treatment procedures, both medical and surgical, are well reflected, as are a number of diseases. Most of the studies are personal works of historical research and represent 3% of the total number of articles. As a whole, the quality is high, and the articles provide data with interesting details and useful reviews, giving them considerable value, as well as forming a precious compendium for the understanding of the history of Spanish urology. These articles are highly recommended reading. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

The present paper firstly reviewed the research progress and main methods of NIR spectral assignment coupled with our research results. Principal component analysis was focused on characteristic signal extraction to reflect spectral differences. Partial least squares method was concerned with variable selection to discover characteristic absorption band. Two-dimensional correlation spectroscopy was mainly adopted for spectral assignment. Autocorrelation peaks were obtained from spectral changes, which were disturbed by external factors, such as concentration, temperature and pressure. Density functional theory was used to calculate energy from substance structure to establish the relationship between molecular energy and spectra change. Based on the above reviewed method, taking a NIR spectral assignment of chlorogenic acid as example, a reliable spectral assignment for critical quality attributes of Chinese materia medica (CMM) was established using deuterium technology and spectral variable selection. The result demonstrated the assignment consistency according to spectral features of different concentrations of chlorogenic acid and variable selection region of online NIR model in extract process. Although spectral assignment was initial using an active pharmaceutical ingredient, it is meaningful to look forward to the futurity of the complex components in CMM. Therefore, it provided methodology for NIR spectral assignment of critical quality attributes in CMM.

European Materia Medica in Historical Texts: Longevity of a Tradition and Implications for Future Use

Recent research in the area of new drug discovery has shown the continued promise of looking to natural products for bioactive compounds. Researchers have thus turned to traditional medicine, which is still used widely throughout the world and increasingly in industrialized countries as well, to provide clues as to which products to investigate. The oral traditions on which much of this medical knowledge rests, however, are unstable, prompting researchers to turn to textual sources for potential drugs. This study uses Mediterranean/European medical texts from the 5th century BC to the 19th century A.D. to compile a list of the most commonly used “simples” – or single action drug substances – used in therapeutics in traditional European medicine. It finds that traditional European materia medica was based on a Dioscordean tradition that lasted through the 19th century with remarkably little variation, but is significantly different from the present-day herbal pharmacopoeia as represented by the National Institutes of Health. The most prominent simples of that tradition can thus provide clues to further bioactive compounds that have not as of yet been fully exploited for their potential, but were clearly of great use in the past.

The schola medica salernitana is considered the oldest medical school of modern civilization. Salerno's long medical tradition began during the Greco-Roman period in a Greek colony named Elea, where Parmenides decided to found a medical school. The fame of the school became more and more important during the 10th century, and it was best known in the 11th century. In the middle of 12th century, the school was at its apogee, and Salerno provided a notable contribution to the formulation of a medical curriculum for medieval universities. The most famous work of the Salernitan School was the Regimen Sanitatis Saleritanum, a Latin poem of rational, dietetic, and hygienic precepts, many of them still valid today. The school also produced a physician's reference book, with advice on how to treat a patient, a sort of code of conduct to help the physician to respect the patient and his or her relatives. The first science-based surgery appeared on the scene of the discredited medieval practice in Salerno, thanks to Roger of Salerno and his fellows. He wrote a book on surgery, called Rogerina or Post Mundi Fabricam, in which surgery from head to toe is described, with surprising originality. The important contribution to the School of Salerno made by women as female practitioners is outlined, and among them, Trotula de Ruggiero was the most renowned. The period when the School of Salerno, universally recognized as the forerunner of the modern universities, became a government academy was when Frederick II reigned over the Kingdom of the Two Sicilies, as Emperor of the Holy Roman Empire.

To establish the unitive multicomponent quality system bridged macrostate mathematic model parameters of material quality and microstate component concentration for Chinese materia medica (CMM). According to law of biologic laws of thermodynamics, the state functions of macrostate qulity of the CMM were established. The validation test was carried out as modeling drug as alcohol extract of Radix Rhozome (AERR), their enthalpy of combustion was determined, and entropy and the capability of information by chromatographic fingerprint were assayed, and then the biologic apparent macrostate parameters were calculated. The biologic macrostate mathematic models, for the CMM quality controll, were established as parameters as the apparent equilibrium constant, biologic enthalpy, Gibbs free energy and biologic entropy etc. The total molarity for the 10 batchs of AERR were 0.153 4 mmol x g(-1) with 28.26% of RSD, with the average of apparent equilibrium constants, biologic enthalpy, Gibbs free energy and biologic entropy were 0.039 65, 8 005 J x mol(-1), -2.408 x 10(7) J x mol(-1) and - 8.078 x 10(4) J x K(-1) with RSD as 6.020%, 1.860%, 42.32% and 42.31%, respectively.

The objective of this study was to evaluate the histo pathology effects of two medicaments Allium sativum oil and formocresol on the remaining pulp tissue of the permanent teething children. A total of 18 premolars were included in this study. Two sound premolars were extracted and subjected to histological examination to show the normal pulp tissue. Pulpo tomy procedure was performed in the rest of the remaining 16 premolars; half of them using Allium sativum oil and the rest of the tested premolars were medicated using formocresol and all were sealed with suitable restoration. Then, premolars extracted at variable intervals (48 hours, 2 weeks, 1 month, 2 months), stained using hemotoxylin and eosin etain (H&E) and prepared for histopathology examination. Histological evaluation seemed far more promising for Allium sativum oil than formocresol. Histological evaluation revealed that teeth treated with Allium sativa oil showed infammatory changes that had been resolved in the end of the study. On the contrary, the severe chronic infammation of pulp tissue accompanied with formocresol eventually produced pulp necrosis with or without fibrosis. In addition, pulp calcification was evidenced in certain cases. Allium sativum oil is a biocompatible material that is compatible with vital human pulp tissue. It offers a good healing potential, leaving the remaining pulp tissue healthy and functioning.

The quality of Chinese materia medica (CMM) is affected by every process in CMM manufacturing. According to multi-unit complex features in the production of CMM, on-line near infrared spectroscopy (NIR) is used as an evaluating technology with its rapid, non-destructive and non-pollution etc. advantages. With the research in institutions, the on-line NIR applied in process analysis and control of CMM was described systematically, and the on-line NIR platform building was used as an example to clarify the feasibility of on-line NIR technology in CMM manufacturing process. Then, from the point of application by pharmaceutical companies, the current on-line NIR research on CMM and its production in pharmaceutical companies was relatively comprehensively summarized. Meanwhile, the types of CMM productions were classified in accordance with two formulations (liquid and solid dosage formulations). The different production processes (extraction, concentration and alcohol precipitation, etc. ) were used as liquid formulation diacritical points; the different types (tablets, capsules and plasters, etc.) were used as solid dosage formulation diacritical points, and the reliability of on-line NIR used in the whole process in CMM production was proved in according to the summary of literatures in recent 10 years, which could support the modernization of CMM production.

Knowledge Discovery in Databases is gaining attention and raising new hopes for traditional Chinese medicine (TCM) researchers. It is a useful tool in understanding and deciphering TCM theories. Aiming for a better understanding of Chinese herbal property theory (CHPT), this paper performed an improved association rule learning to analyze semistructured text in the book entitled Shennong's Classic of Materia Medica. The text was firstly annotated and transformed to well-structured multidimensional data. Subsequently, an Apriori algorithm was employed for producing association rules after the sensitivity analysis of parameters. From the confirmed 120 resulting rules that described the intrinsic relationships between herbal property (qi, flavor and their combinations) and herbal efficacy, two novel fundamental principles underlying CHPT were acquired and further elucidated: (1) the many-to-one mapping of herbal efficacy to herbal property; (2) the nonrandom overlap between the related efficacy of qi and flavor. This work provided an innovative knowledge about CHPT, which would be helpful for its modern research.

To investigate the AAPH scavenging activities of 22 flavonoids and phenolic acids and 9 extracts of Chinese materia medica. The antioxidant activities of the samples were evaluated by an oxygen radical absorbance capacity method (ORAC), at the same time, the total contents of flavonoids and phenolic the 9 herb extracts were analyzed by Folin-Ciocalteu method, and the active components were qualitatively and quantitatively analyzed by an HPLC method. It was found that the tea extract showed the strongest AAPH activity with the ORAC value of 4786.40 micromol x g(-1) whereas safflower demonstrated the weakest activity with the ORAC value of 784.04 micromol x g(-1). As for compounds, quercetin had the strongest AAPH activity with the ORAC value of 12.90 while ( - )-EGC had the weakest activity with the ORAC value of 2.47. A quantitative relationship was obtained to describe the AAPH scavenging activity of the herb extracts: Y = 1844.8 lnX-3577.5, r = 0.8675, where Y stands for the ORAC vaule, and X stands for the concentration of total phenolic acids. Flavonoids and phenolic acids are the AAPH scavenging active ingredients in the Chinese herb extracts. It's a good way to study the antioxidant activity of Chinese herb extract and its chemical composition by combing ORAC method and HPLC method.

Chinese materia medica (CMM), including Chinese herbal, animal, and mineral medicine, has been widely researched in the past century for their biological and pharmacological activities. However, their mechanism and clinical efficacy studies did not always give expected results. For example, the most commonly used Chinese herb for menstrual disorders, Radix Angelicae sinensis, showed neither estrogenic nor progesteronic activity in laboratory and clinical studies. Its efficacy should not be denied simply based on such results, because it is mostly used together with other herbs in formulae. Moreover, its regulation on menstruation may take effect through other mechanisms, such as regulation of blood circulation. The key difference of Chinese medicine (CM) from conventional medicine is its unique holistic view on human body and diseases. CMM is mostly applied in clinic in the form of formulae. Study on individual CMM, simply using methods for development of conventional drugs, is unable to thoroughly reveal the power of CMM formulae. The reason may partly result from improper design due to the lack understanding about application principle of CMMs in CM, and/or to current lack of knowledge about the causes of some symptoms and diseases. This paper will introduce the importance of qi and blood in CM etiology and pathology, Zheng differentiation, formulation of CMMs, and explain why one formula can treat different diseases and one disease can be treated with different formulae. Examples in the paper will demonstrate that proper studies on Zheng and its corresponding clinically proven formulae could help scientists find new direction to explain and treat symptoms and diseases that so far modern medicine has been unable to, provided that the designer properly understands CM theories, etiology and pathology of CM, as well as modern medicine. Strategy suggestions about research methods for CMM and its formulae will be given at the end.

Increasing birth rates have raised questions for policy makers and hospital management about the economic costs of childbirth. The purpose of this article is to identify and review all existing scientific studies in relation to the economic costs of alternative modes of childbirth delivery and to highlight deficiencies in the existing scientific research. We searched Cochrane, Centre for Reviews and Dissemination, EconLit, the Excerpta Medica Database, the Health Economic Evaluations Database, MEDLINE and PubMed. Thirty articles are included in this review. The main findings suggest that there is no internationally acceptable childbirth cost and clinical outcome classification system that allows for comparisons across different delivery modes. This review demonstrates that a better understanding and classification of the costs and associated clinical outcomes of childbirth is required to allow for valid comparisons between maternity units, and to inform policy makers and hospital management. © 2013 The Authors Acta Obstetricia et Gynecologica Scandinavica © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

The Chinese Materia Medica, Tiepishihu, used as a tonic for over one thousand years, is a well-known precious medicine in China. According to the Chinese Pharmacopoeia, its source is the species Dendrobium officinale Kimura et Migo, which is distinguished from other species in Dendrobium genus. However, these species from the same genus are similar with Tiepishihu and caused confusion in the market. To find a quick and simple method to distinguish Tiepishihu from other similar species, histologic and microscopic methods were combined together to investigate the transverse section of stem of Tiepishihu and other similar species. Phloroglucinol test solution with hydrochloric acid was used to reveal the lignified tissue by staining the transverse section of Tiepishihu and similar species. Results revealed the unique identification characteristics to distinguish Tiepishihu from similar species, which were difficult to distinguish by other methods. The identification characteristics of Tiepishihu include the cells of vascular bundle sheath were stained red, parenchyma cells were not stained red. What's more, other species can be distinguished from each other with microscopic and histological characteristics. These characteristics proved stable and can be easily observed by normal light microscopic examination. This method is rapid, accurate, stable, and inexpensive. © 2017 Wiley Periodicals, Inc.

Vascular disease-causing mutation R258C in ACTA2 disrupts actin dynamics and interaction with myosin

Point mutations in vascular smooth muscle α-actin (SM α-actin), encoded by the gene ACTA2, are the most prevalent cause of familial thoracic aortic aneurysms and dissections (TAAD). Here, we provide the first molecular characterization, to our knowledge, of the effect of the R258C mutation in SM α-actin, expressed with the baculovirus system. Smooth muscles are unique in that force generation requires both interaction of stable actin filaments with myosin and polymerization of actin in the subcortical region. Both aspects of R258C function therefore need investigation. Total internal reflection fluorescence (TIRF) microscopy was used to quantify the growth of single actin filaments as a function of time. R258C filaments are less stable than WT and more susceptible to severing by cofilin. Smooth muscle tropomyosin offers little protection from cofilin cleavage, unlike its effect on WT actin. Unexpectedly, profilin binds tighter to the R258C monomer, which will increase the pool of globular actin (G-actin). In an in vitro motility assay, smooth muscle myosin moves R258C filaments more slowly than WT, and the slowing is exacerbated by smooth muscle tropomyosin. Under loaded conditions, small ensembles of myosin are unable to produce force on R258C actin-tropomyosin filaments, suggesting that tropomyosin occupies an inhibitory position on actin. Many of the observed defects cannot be explained by a direct interaction with the mutated residue, and thus the mutation allosterically affects multiple regions of the monomer. Our results align with the hypothesis that defective contractile function contributes to the pathogenesis of TAAD. PMID:26153420

The Doctrine of Signatures, Materia Medica of Orchids, and the Contributions of Doctor - Orchidologists.

Pearn, John

2012-12-01

The heritage of medicine is written in many forms. One repository is to be found in the history of orchids, the world's largest family of flowering plants. Orchids were so named by Theophrastus (c.372-288 BC) who recorded their medicinal use as an aphrodisiac and the promoter of virility, in the context of the Doctrine of Signatures. Such use endured for millennia, and was recorded both by Paracelsus (1493-1551) and Linnaeus (1707-1778). The history of orchidology and medicine are entwined in four domains: (a) orchids and their historical materia medica, within the paradigm of the Doctrine of Signatures; (b) the enduring and extensive contemporary medicinal and culinary use of orchids such as Vanilla and salep extracts of Orchis; (c) the scientific contributions of doctors as orchidologists; and (d) the heritage of more than a hundred doctors' names in the scientific etymology of the Orchidaceae family. Prominent orchidologists have included the Scottish doctor-soldier and botanist, Robert Brown (1773-1858); the Director of the State Herbarium at Leyden and the Rijks Museum, Carl Ludwig Blume (1796-1862); and Dr William Sterling MD (1888-1967). Among the more than 1250 genus names (and 33,000 species) of orchids are the names of more than a hundred doctors, their lives and works perpetuated in the scientific etymology of this family of exotic, beautiful, flamboyant, intriguing and often expensive flowers. Generic names record the lives and works of such as Aristotle (384-322BC) in Aristotelia Loureiro 1790; Cadet de Gassicourt (1769-1821) in Cadetia Gaudichaud 1826; Sir Joseph Dalton Hooker (1817-1911) in Sirhookera O. Kuntze 1891; and Dr Theodore Daniel Vrydag Zynen (fl. 1820-1850) in Vrydagzynea Blume 1858. One of the principal horticultural genera of orchids, Brassavola, records the life and work of the Ferrara and Padua physician and botanist, Antonio Musa Brassavola (1500-1555).

Ischemic stroke and ischemia/reperfusion (I/R) injury induced by thrombolytic therapy are conditions with high mortality and serious long-term physical and cognitive disabilities. They have a major impact on global public health. These disorders are associated with multiple insults to the cerebral microcirculation, including reactive oxygen species (ROS) overproduction, leukocyte adhesion and infiltration, brain blood barrier (BBB) disruption, and capillary hypoperfusion, ultimately resulting in tissue edema, hemorrhage, brain injury and delayed neuron damage. Traditional Chinese medicine (TCM) has been used in China, Korea, Japan and other Asian countries for treatment of a wide range of diseases. In China, the usage of compound TCM preparation to treat cerebrovascular diseases dates back to the Han Dynasty. Even thousands of years earlier, the medical formulary recorded many classical prescriptions for treating cerebral I/R-related diseases. This review summarizes current information and underlying mechanisms regarding the ameliorating effects of compound TCM preparation, Chinese materia medica, and active components on I/R-induced cerebral microcirculatory disturbances, brain injury and neuron damage.

The chemical composition of the essential oil of Citrus medica L. cv. Diamante peel obtained by hydrodistillation, cold-pressing and supercritical carbon dioxide extraction techniques was determined by GC/MS analysis. Forty-six components were fully characterised. Limonene and γ-terpinene were the major components of the oils obtained by hydrodistillation (HD) and cold-pressing (CP), while citropten was the major constituent in the oil obtained by supercritical carbon dioxide extraction (SFE). Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities were evaluated. The essential oil obtained by hydrodistillation exerted the highest inhibitory activity against BChE (IC₅₀ value of 154.6 µg mL⁻¹) and AChE (IC₅₀ value of 171.3 µg mL⁻¹. Interestingly, the oil obtained by cold-pressing exhibited a selective inhibitory activity against AChE. The essential oils have also been evaluated for the inhibition of NO production in LPS induced RAW 264.7 macrophages. The oil obtained by hydrodistillation exerted a significant inhibition of NO production with an IC₅₀ value of 17 µg mL⁻¹ (IC₅₀ of positive control 53 µg mL⁻¹).

To quantify the impact factor of the journal Actas Dermo-Sifiliográficas (AD) from 1986 to 1990 and from 1999 to 2003 and to identify the journal's citation pattern in those years. Citations obtained by AD in the periods from 1985-1990 and 1998-2003 for articles published from 1984 to 1989 and from 1997 to 2002 were collected using Science Citation Index Expanded (SCI). The number of times AD was cited doubled during the second period, increasing from 38 (period from 1985-1990) to 76 (period from 1998-2003). Considering the number of citations, AD's impact factor increased from 0.016 in 1986 to 0.040 in 2003. In both periods, citations corresponding to AD articles were included in a wide range of source journals, mainly dermatological publications abroad. The most referred journals in the second period were the Dutch publication Journal of the European Academy of Dermatology and Venereology (13 citations) and the Journal of the American Academy of Dermatology (12 citations). Unlike the period from 1985 to 1990 when no Spanish journal cited AD, four Spanish publications mentioned AD in the second period: Revista clínica española (6 citations), Archivos de bronconeumología (4 citations), Medicina clínica (3 citations) and the journal Enfermedades infecciosas y microbiología clínica (1 citation). Citations mainly corresponded to articles published by Spanish authors (63.2 % in the 1985-1990 period and 81.6 % in the period from 1998 to 2003). Self-citation increased from 10.5 % (first period) to 31.6 % (second period). The impact factor of AD is low and not comparable to other publications included in the Dermatology and Venereal Diseases field from SCI. Our results confirm the low citation rate of AD by source journals in this repertory. However, the increase of this rate in recent years seems to indicate a higher Spanish presence in SCI due to an increasing number of publications corresponding to Spanish authors in international journals and the inclusion of

The properties of Chinese materia medica are believed to be the summarization of the effects of biological performance on the various body states. Systemic discussion of chemical-factor elements, body-condition elements, biological-performance elements and their interrelationships is needed for research into the properties of Chinese materia medica. Following the practical characteristics of Chinese medicine, the three-element mathematical model was formed by introducing some mathematical concepts and methods and was used to study the cold or hot property of Chinese medicine, and to investigate the difference in biological performances of the two properties. By using the concept of different functionality of Chinese medicine on abnormal states and the idea of interaction in mathematics, the effects of chemical-factor elements and body-condition elements were normalized to the amount of biological performance which was represented by some important indicators. The three-element mathematical model was formed with scatter plots through four steps, including effect separation, intensity calculation, frequency statistics and relevance analysis. A comparison pharmacology experiment of administration of hot property medicines, Fuzi (Radix Aconiti Lateralis Preparata) and Rougui (Cortex Cinnamomi), and cold property medicines, Huangbai (Cortex Phellodendri) and Zhizi (Fructus Gardeniae) on normal and glucocorticoid-induced yang-deficiency and yin-deficiency states was designed. The results were analyzed by the mathematical model. The scatter plots were the main output of model analysis. The expression of cold property and hot property was able to be quantified by frequency distribution of biological indexes of administrations on yang-deficiency and yin-deficiency states in the "efficacy zone" and "toxicity zone" of the plots and by the relevance analysis. The ratios of biological indicator frequency in the "efficacy zone" of administrations on yang-deficiency state and yin

The 15th volume of the Acta Historica Astronomiae is at the same time the fifth collection of essays on the history of astronomy (Beitraege zur Astronomiegeschichte, Band 5), edited by the historians of astronomy W.R. Dick (Potsdam) and J. Hamel (Berlin). Besides a few short notices and book reviews, the book contains 11 major articles, which deal with astronomical topics covering the time from the 16th to the 20th centuries. The first article, on the analysis and interpretation of historical horoscopes as a source of the history of science, is based on the inaugural lecture of its author, Guenther Oestmann. After a general introduction, which deals with the principles of horoscope making, the author discusses the horoscope of Count Heinrich Ranzau (1526-1598), the Danish governor of Schleswig-Holstein, who was a friend of Tycho Brahe. Oestmann shows that the astronomical-mathematical basis of such a horoscope can be reconstructed and interpreted. However, it is hardly possible to gain an insight in the process how the interpretation of a horoscope was done in detail. The second and third articles, by Franz Daxecker, deal with Athanasius Kircher and Christoph Scheiner, two catholic astronomers of the 17th century. Kircher's Organum Mathematicum is a calculating device that can be used in the fields of arithmetic, geometry, chronology, astronomy, astrology and others. The author provides extracts of the description of the Organum taken from a book by Caspar Schott, which deal with chronology and astronomy. A photograph of the Organum indicates that this tool consists of a set of tables glued on wooden or cardboard, but details of its contents and applications remain pretty obscure for the reader - a few elaborated examples would have been helpful. The second paper deals with the life of Christoph Scheiner SJ, the co-discoverer of sunspots (next to Galileo), after leaving Rome in 1633 - the year of the Galileo trial. Scheiner spent his later years in the Austrian and

Aims: Evaluation of calcium ion and hydroxyl ion release and pH levels in various calcium hydroxide based intracanal medicaments. Objective: The purpose of this study was to evaluate calcium and hydroxyl ion release and pH levels of calcium hydroxide based products, namely, RC Cal, Metapex, calcium hydroxide with distilled water, along with the new gutta-percha points with calcium hydroxide. Materials and Methods: The materials were inserted in polyethylene tubes and immersed in deionized water. The pH variation, Ca++ and OH- release were monitored periodically for 1 week. Statistical Analysis Used: Statistical analysis was carried out using one-way analysis of variance and Tukey's post hoc tests with PASW Statistics version 18 software to compare the statistical difference. Results: After 1 week, calcium hydroxide with distilled water and RC Cal raised the pH to 12.7 and 11.8, respectively, while a small change was observed for Metapex, calcium hydroxide gutta-percha points. The calcium released after 1 week was 15.36 mg/dL from RC Cal, followed by 13.04, 1.296, 3.064 mg/dL from calcium hydroxide with sterile water, Metapex and calcium hydroxide gutta-percha points, respectively. Conclusions: Calcium hydroxide with sterile water and RC Cal pastes liberate significantly more calcium and hydroxyl ions and raise the pH higher than Metapex and calcium hydroxidegutta-percha points.

The cold/hot property of Chinese materia medica (CMM) and the application of its corresponding knowledge in the diagnosis, differentiation and treatment of diseases have been considered to be the extremely important part of traditional Chinese medicine (TCM). As highly abstracted TCM theory, the cold/hot property of CMMs is still not fully understood and remains to be elucidated by systems biology approach. The cold and hot properties of CMM are mainly defined by the response of the body to a given CMM. Metabolomics is a promising systems biology method to profile entire endogenous metabolites and monitor their fluctuations related to an exogenous stimulus. Thus, a metabolomics approach was applied to characterize the cold and hot properties of CMMs. Mice were intragastrically administered three selected cold property CMMs (i.e., Rheum palmatum L., radix et rhizoma; Coptis chinensis Franch, rhizome and Scutellaria baicalensis Georgi, radix) and three hot property CMMs (i.e., Cinnamomum cassia (L.) J. Presl, cortex; Zingiber officinale Roscoe, rhizoma and Evodia rutaecarpa (Juss.) Benth., fructus) once daily for one week. The comprehensive metabolome changes in the plasma of mice after treatment with cold or hot property CMMs were characterized by ultra-high performance liquid chromatography/time of flight mass spectrometry (UHPLC/Q-TOF-MS), and the potential biomarkers related to cold and hot properties of CMM were explored. Metabolites perturbation in plasma occurs after treatment with cold CMMs and hot CMMs in mice, and 15 and 16 differential biomarkers were identified to be associated with the cold and hot properties of CMMs, respectively. Among them, LPC (18:0), LPC (18:1), LPC (20:4) and LPC (20:5) showed decreased trends in the cold property CMM treated groups, but increased in the hot property CMM treated groups. There is a strong connection between the cold/hot property of CMMs and lysophosphatidylcholines metabolism. This study offers new insight

Discrepancies were found between the user's and the program's information, observing different levels of agreement: Absence of physician and administrative staff member 0%; Transfer to other service 25%; Death 50%; Option to quit 50%; Address change 57% and Change in therapeutic schedule 80%. The users' feeling of accepting the program was observed. In the health access concept, inactivity can be explained in the information dimension, in the degree of asymmetry between the patient's and the health professional's knowledge, identified through the indicators: education, knowledge and information sources. due to the low education level, the user does not assimilate the information on the steps of the program flowchart, does not return for the assessment that guarantees its continuity. Consequently, (s)he stops receiving the medication and spends a long time without treatment, increasing the cardiovascular risk of hypertensive (92% of the sample), diabetic (44%) and dyslipidemic patients (31%). verificar causas de inatividade no Programa Remédio em Casa, referidas por usuários de Unidade Básica de Saúde de São Paulo, comparando-as às registradas pelo programa e analisando-as no modelo teórico Conceito de Acesso à Saúde. estudo transversal entrevistando 111 usuários inativos; e documental, nos registros do programa. metade dos usuários desconhecia a condição de inatividade.

Group II introns are self-splicing catalytic RNAs that act as mobile retroelements. In bacteria, they are thought to be tolerated to some extent because they self-splice and home preferentially to sites outside of functional genes, generally within intergenic regions or in other mobile genetic elements, by mechanisms including the divergence of DNA target specificity to prevent target site saturation. RmInt1 is a mobile group II intron that is widespread in natural populations of Sinorhizobium meliloti and was first described in the GR4 strain. Like other bacterial group II introns, RmInt1 tends to evolve toward an inactive form by fragmentation, with loss of the 3' terminus. We identified genomic evidence of a fragmented intron closely related to RmInt1 buried in the genome of the extant S. meliloti/S. medicae species. By studying this intron, we obtained evidence for the occurrence of intron insertion before the divergence of ancient rhizobial species. This fragmented group II intron has thus existed for a long time and has provided sequence variation, on which selection can act, contributing to diverse genetic rearrangements, and to generate pan-genome divergence after strain differentiation. The data presented here suggest that fragmented group II introns within intergenic regions closed to functionally important neighboring genes may have been microevolutionary forces driving adaptive evolution of these rhizobial species.

To evaluate the methodological quality and reporting quality of randomized controlled trials(RCTs) published in China Journal of Chinese Materia Medica, we searched CNKI and China Journal of Chinese Materia webpage to collect RCTs since the establishment of the magazine. The Cochrane risk of bias assessment tool was used to evaluate the methodological quality of RCTs. The CONSORT 2010 list was adopted as reporting quality evaluating tool. Finally, 184 RCTs were included and evaluated methodologically, of which 97 RCTs were evaluated with reporting quality. For the methodological evaluating, 62 trials(33.70%) reported the random sequence generation; 9(4.89%) trials reported the allocation concealment; 25(13.59%) trials adopted the method of blinding; 30(16.30%) trials reported the number of patients withdrawing, dropping out and those lost to follow-up;2 trials （1.09%） reported trial registration and none of the trial reported the trial protocol; only 8(4.35%) trials reported the sample size estimation in details. For reporting quality appraising, 3 reporting items of 25 items were evaluated with high-quality,including: abstract, participants qualified criteria, and statistical methods; 4 reporting items with medium-quality, including purpose, intervention, random sequence method, and data collection of sites and locations; 9 items with low-quality reporting items including title, backgrounds, random sequence types, allocation concealment, blindness, recruitment of subjects, baseline data, harms, and funding;the rest of items were of extremely low quality(the compliance rate of reporting item<10%). On the whole, the methodological and reporting quality of RCTs published in the magazine are generally low. Further improvement in both methodological and reporting quality for RCTs of traditional Chinese medicine are warranted. It is recommended that the international standards and procedures for RCT design should be strictly followed to conduct high-quality trials

The 18th volume of the Acta Historica Astronomiae is at the same time the sixth collection of essays on the history of astronomy ("Beitræge zur Astronomiegeschichte, Band 6"), edited by the historians of astronomy W.R. Dick (Potsdam) and J. Hamel (Berlin). Besides a few short notices and book reviews, the book contains eight major articles, which deal with astronomical topics covering the time from the 16th to the 19th centuries. The first article by Michael Weichenhan (Berlin) deals with "the invention of the disk-shaped earth: a chapter of Copernican apologetics". The author shows that the concept of a "disc-shaped Earth" was by no means widespread in the middle ages, but restricted to the father of the church Lactantius and some adherents. Nevertheless, it was used by adherents of Copernicus to show the absurd consequences of a strictly literal biblical interpretation -- here concerning the Earth's shape, disc versus sphere, there the geocentric versus the heliocentric system. This thorough philosophical study is followed by two very short articles. "The measuring accuracy of Tycho's large sextant" by Johann Wünsch investigates O-C values of planet-star distances, as based on Tycho's observations as published in the Historia Coelestis (a compilation, which is also based on Tycho's manuscripts, and published in Regensburg in 1672). The result is that standard deviations are 80 arcseconds for Saturn and 89 arcseconds for Jupiter and Mars, an unexpectedly poor result in view of the general opinion that Tycho was famous for his precision work. "The astronomer Christoph Grienberger and the Galilei trial" by Franz Daxecker deals with a Jesuit astronomer who was both the disciple and successor of the mathematician-astronomer Christopher Clavius at the Collegium Romanum. While he was inclined to Galilei early on, he was forced to propagate Aristotelian doctrine. The brief article is very concise, but extremely tiresome to read (3 pages of pure text are embellished by

Yuzhu (Polygonati Odorati Rhizoma), Kangdingyuzhu (Polygonati Prattii Rhizoma), and zhugenqiyuzhu (Disporopsis Fuscopictae Rhizoma) are of the same family, but of different genera. They have all often used in Chinese Materia Medica (CMM) as Polygonati Odorati Rhizoma in China market. Three species of CMM are confused. For better application, we need to identify these plants accurately. This study use pharmacognosy technique and GC-MS analysis, three species of CMM were authenticated. In macroscopic characteristics, the fruit of Polygonati Odorati Rhizoma is blue-black, while the other two are maroon and dark purple orderly. Nodes of Polygonati Odorati Rhizoma are upward and light uplift, about 1 cm spacing, while the other are not. As for microscopic characteristics, the cortex of Polygonati Odorati Rhizoma only occupies about 1/5 of the radius of the transverse section with inconspicuous endodermis, which is much smaller than others. The type of vascular bundles of Polygonati Odorati Rhizoma is closed collateral, but the other is amphivasal. Raphides of calcium oxalate are scattered, but Raphides of the other two are like brooms and neat rows. GC-MS analysis of essential oil could provide different characteristics to distinguish three species. Twenty-three compounds were identified from essential oil of Polygonati Odorati Rhizoma and the main components were n-hexadecanoic acid (49.45%), while n-hexadecanoic acid of the other two are 23.92% and 9.45%. The content of n-hexadecanoic is strongly different. This research was aimed to establish a method by pharmacognosy and GC-MS analysis to identify three CMM and for providing scientifical data to ensure accuracy of origin of three species. © 2014 Wiley Periodicals, Inc.

In Persian ethnomedicine several herbal remedies and functional foods have been used to treat migraine headache which are mostly summarized in Qarabadin-e-kabir (Aghili-Shirazi MH, 1773). One of them is Citron syrup (Sharbat-e-Balang) containing edible Citrus medica L. fruit juice and sugar. The present study was designed to assess the efficacy and safety of Citron syrup on patients with migraine headache. Citron syrup was prepared as described in Qarabadin-e-kabir. In this double blind randomized placebo-controlled clinical trial, ninety patients with migraine headache were allocated to three parallel groups (Citron syrup, propranolol or placebo). Patients received 15ml of Citron syrup, placebo syrup or 20mg of propranolol tablet three times daily after a meal for 4 weeks. Primary outcomes were obtained from three measures: the frequency (per month), mean duration (hour) and mean intensity (visual analogue scale "VAS" 0-10 score) of headache attacks evaluated prior to and following 4 weeks of the intervention. Citron syrup was superior to placebo in reduction of headache attacks intensity (P<0.01) and duration (p<0.0001) and as effective as propranolol in patients with migraine headache (P>0.05). However, unlike propranolol, Citron syrup could not significantly reduce the frequency of attacks compared to placebo. No indication of any serious side effects from Citron syrup was observed. According to obtained results, Citron syrup as a traditional Persian remedy can be suggested as an effective treatment for decreasing pain intensity and duration of attacks in migraine headache and the effectiveness is comparable to propranolol. However, the syrup did not show significant effect on frequency of attacks. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

This paper aims to summarize the achievements during the implementation process of good agricultural practice (GAP) in Chinese Materia Medica (CMM), and on basis of analyzing the existing problems of GAP, to propose further implementation of GAP in TCM growing. Since the launch of GAP in CMM growing ten years ago, it has acquired great achievements, including: (1) The promulgation of a series of measures for the administration of the GAP approval in the CMM growing; (2) The expanded planting area of CMM; (3) The increased awareness of standardized CMM growing among farmers and enterprises; (4) The establishment of GAP implementation bases for CMM growing; (5) The improvement of theory and methodology for CMM growing; (6) The development of a large group of experts and scholars in GAP approval for CMM production. The problems existing in the production include: (1) A deep understanding of GAP and its certification is still needed; (2) The distribution of the certification base is not reasonable; (3) The geo-economics effect and the backward farming practices are thought to be the bottlenecks in the standardization of CMM growing and the scale production of CMM; (4) Low comparative effectiveness limits the development of the GAP; (5) The base of breeding improved variety is blank; (6) The immature of the cultivation technique lead to the risk of production process; (7) The degradation of soil microbial and the continuous cropping obstacle restrict the sustainable development of the GAP base. To further promote the health and orderly GAP in the CMM growing, the authors propose: (1) To change the mode of production; (2) To establish a sound standard system so as to ensure quality products for fair prices; (3) To fully consider the geo-economic culture and vigorously promote the definite cultivating of traditional Chinese medicinal materials; (4) To strengthen the transformation and generalization of basic researches and achievements, in order to provide technical

In recent years, effective models of disaster medicine curricula for medical schools have been established. However, only a small percentage of medical schools worldwide have considered at least basic disaster medicine teaching in their study program. In Italy, disaster medicine has not yet been included in the medical school curriculum. Perceiving the lack of a specific course on disaster medicine, the Segretariato Italiano Studenti in Medicina (SISM) contacted the Centro di Ricerca Interdipartimentale in Medicina di Emergenza e dei Disastri ed Informatica applicata alla didattica e alla pratica Medica (CRIMEDIM) with a proposal for a nationwide program in this field. Seven modules (introduction to disaster medicine, prehospital disaster management, definition of triage, characteristics of hospital disaster plans, treatment of the health consequences of different disasters, psychosocial care, and presentation of past disasters) were developed using an e-learning platform and a 12-hour classroom session which involved problem-based learning (PBL) activities, table-top exercises, and a computerized simulation (Table 1). The modules were designed as a framework for a disaster medicine curriculum for undergraduates and covered the three main disciplines (clinical and psychosocial, public health, and emergency and risk management) of the core of "Disaster Health" according to the World Association for Disaster and Emergency Medicine (WADEM) international guidelines for disaster medicine education. From January 2011 through May 2013, 21 editions of the course were delivered to 21 different medical schools, and 524 students attended the course. The blended approach and the use of simulation tools were appreciated by all participants and successfully increased participants' knowledge of disaster medicine and basic competencies in performing mass-casualty triage.

Self-medication is a means, besides changing one's lifestyle, of buying and taking non-prescription medicaments. This practice has several advantages. People save time and energy by not sitting for hours in the consulting room of the doctor with a simple ailment, and the doctors also have more time to deal with those requiring more serious treatment. Moreover, the expenditures of the state also decrease, as patients do not visit the doctor but buy non-prescription, i.e. non-supported, medicaments. The authors surveyed the habits and demands of a survey population concerning non-prescription medicaments, primarily in the pharmacies of Fejér county. A marketing research programme was completed in order to establish better co-operation between patients and pharmacists, within the framework of which 1450 questionnaires were distributed from March to June in 2005, 743 of which were completed and evaluated. The authors examined, whether there were differences within the answers given to professional questions (questions 1-25 of the questionnaire) through sex, age, qualifications and earning power. Answers were analyzed by statistical methods. Statistical analyses were carried out with the SPSS 13.0 program group. Those results were published, where significant differences were found. Half of the respondents take medicaments regularly, 65% of them watch advertisements about medicaments several times a day. 40% of those surveyed consult a professionally-qualified person about their decision before buying non-prescription medicaments. The population obtains much information from the brochures enclosed with medicaments, and almost 70% of them read these brochures. According to their opinions, when buying non-prescription products, pharmacists always recommend other possibilities as well, and they give details about the information concerning the application of the medicaments. In order for people to use non-prescription products properly, it would be definitely necessary to

Actin isoform specificity is required for the maintenance of lactation

PubMed Central

Weymouth, Nate; Shi, Zengdun; Rockey, Don C.

2014-01-01

Smooth muscle α-actin (Acta2) is one of six highly conserved mammalian actin isoforms that appear to exhibit functional redundancy. Nonetheless, we have postulated a specific functional role for the smooth muscle specific isoform. Here, we show that Acta2 deficient mice have a remarkable mammary phenotype such that dams lacking Acta2 are unable to nurse their offspring effectively. The phenotype was rescued in cross fostering experiments with wild type mice, excluding a developmental defect in Acta2 null pups. The mechanism for the underlying phenotype is due to myoepithelial dysfunction postpartum resulting in precocious involution. Further, we demonstrate a specific defect in myoepithelial cell contractility in Acta2 null mammary glands, despite normal expression of cytoplasmic actins. We conclude that Acta2 specifically mediates myoepithelial cell contraction during lactation and that this actin isoform therefore exhibits functional specificity. PMID:22123032

To establish the environmental endocrine disruptors (EEDs) induced precocious puberty macaca fascicularis model, thus verifying the antagonism of yin nourishing fire purging Chinese materia medica (YNFPCMM) against the estrogenic effects. (1) The female prepubescent monkeys at different months old were fed with high dose and low dose EEDs. By observing EEDs' estrogenic effects, the optimal age, the optimal exposure dose, and the optimal exposure time were determined. (2) Fifteen female prepubescent monkeys were randomly divided into the exposure group, the treatment group, and the control group, 5 in each group. Those in the exposure group were fed with EEDs such as nonylphenol (4-NP) and bisphenol A (BPA). Those in the treatment group were fed with EEDs and YNFPCMM. Those in the control group were fed with dissolvent such as corn oil. The therapeutic course was 4 weeks. By the end of the treatment, the serum estrogen level was measured and the maturation index of the vaginal keratinocytes was calculated. The uterus was extracted to measure the wet weight, the endometrial thickness, the ring-shaped myometrium thickness, the endometrial epithelial cells, and the glandular epithelium height. (1) Twenty month was the optimal exposure age. The low dose EEDs was the best exposure dose, and 4 weeks was the optimal exposure time. (2) Compared with the control group, the serum estrogen level obviously increased, the maturation index of the vaginal keratinocytes significantly increased, the wet uterus weight, the endometrial thickness, the ring-shaped myometrium thickness, the endometrial epithelial cells, and the glandular epithelium height significantly increased in the exposure group (P<0.05). Compared with the exposure group, the aforesaid indices significantly decreased in the treatment group (P<0.05). The EEDs induced precocious puberty macaca fascicularis model was successfully established in this study. The EEDs were proved to have estrogenic-like activities. YNFPC

The use of x rays to sterilize ophthalmological pharmaceutical preparations is described, particularly penicillin and fluorescein drops. The method used with penicillin is to place a tablet (1500 units) in a small vial which is closed with a cork and attached with Sellotape to a 5-ml eye-drop bottle containing 3 ml of normal saline. The bottles were sealed in two polythene envelopes and irradiated at the Wantage Research Lab (AERE) at a dose of 2.5 Mrad. The bags are then stored in a refrigerator at 4 deg C. When required for operation, the outer bag is opened with sterile scissors,more » and the contents tipped onto the surface of the sterile instrument tray. The dropper bulb is filled with saline and introduced into the vial, thereby dissolving the tablet of penicillin. All irradiated preparations were found to be absolutely sterile and fully potent. In the case of fluorescein, 1-in. lengths of gauge 2-intraarterial polythene tubes are filled with the dye from a syringe, and the ends of the tube sealed in a flame. Several hundreds of tubes are irradiated in a single container, and when required, one end of the tube is cut off and a drop squeezed out into the conjunctival sac. (BBB)« less

According to the World Health Organization, rational drug use means that patients receive medicines appropriate to their clinical needs, in doses that meet their individual requirements, for an adequate period of time, and at the lowest cost to them and their community. However, as far as one can see, the reality is very different. In Brazil, at least, 35% of medicines are purchased for self-medication. Medicaments are responsible for 27% of intoxications in Brazil and for 16% of deaths due to poisoning are caused by medicaments. Moreover, 50% of medicaments are prescribed, dispensed or used inappropriately and hospitals spend about 15 to 20% of their budgets to deal with the troubles caused by misuse of medicaments. The promise of immediate relief of suffering is a very attractive appeal, but it has its price. Sometimes the price we pay is our health. Rational drug use requires a very complex logical chain involving a number of variables and participation of different social actors including patients, health professionals, legislators, policy makers, industry, commerce and the government.

Insulin sensitizer prevents and ameliorates experimental type 1 diabetes.

2017-12-01

Insulin-dependent type-1 diabetes (T1D) is driven by autoimmune β-cell failure, whereas systemic resistance to insulin is considered the hallmark of insulin-independent type-2 diabetes (T2D). In contrast to this canonical dichotomy, insulin resistance appears to precede the overt diabetic stage of T1D and predict its progression, implying that insulin sensitizers may change the course of T1D. However, previous attempts to ameliorate T1D in animal models or patients by insulin sensitizers have largely failed. Sensitization to insulin by MEthyl-substituted long-chain DICArboxylic acid (MEDICA) analogs in T2D animal models surpasses that of current insulin sensitizers, thus prompting our interest in probing MEDICA in the T1D context. MEDICA efficacy in modulating the course of T1D was verified in streptozotocin (STZ) diabetic rats and autoimmune nonobese diabetic (NOD) mice. MEDICA treatment normalizes overt diabetes in STZ diabetic rats when added on to subtherapeutic insulin, and prevents/delays autoimmune T1D in NOD mice. MEDICA treatment does not improve β-cell insulin content or insulitis score, but its efficacy is accounted for by pronounced total body sensitization to insulin. In conclusion, potent insulin sensitizers may counteract genetic predisposition to autoimmune T1D and amplify subtherapeutic insulin into an effective therapeutic measure for the treatment of overt T1D.

An efficient antimicrobial agent action is required for a predetermined time period for absolute elimination of root canal microbes. Till date, there is limited or no data on the antimicrobial effect of octenidine as an intracanal medicament with chitosan (CTS) as a carrier against Candida albicans and Enterococcus faecalis . The aim of this microbiological study was to compare the antimicrobial efficacy of octenidine hydrochloride (OHC) and calcium hydroxide (Ca[OH] 2 ) as intracanal medicaments, both independently and along with CTS as a carrier molecule against the common resistant endodontic pathogens. A total of 160 single-rooted anterior teeth were selected, root canal preparation was done, and teeth were divided into two groups and contaminated with C. albicans and E. faecalis , which were further divided into four test groups each according to intracanal medicaments used. CTS was used as a vehicle for OHC and Ca(OH) 2 and antimicrobial assessment was performed on day 2 and day 7 following broth dilution method. Dentine samples were collected after each time interval, and the number of colony-forming units was determined. All four medicaments used in this study showed antifungal and antibacterial activity that diminished from day 2 to day 7. Group I (OHC alone) and Group IV (Ca[OH] 2 alone) showed significant antimicrobial activity against C. albicans and E. faecalis , respectively, than the other groups. A combination of OHC + CTS and Ca(OH) 2 + CTS produced inferior results than that of the medicaments used alone.

Author of this paper spent 1479 days in the siege of Sarajevo, during the period of war time in Bosnia and Herzegovina (B&H). This siege, lasting from 1992 to 1995 (e.g. Dayton Piece agreement was signed in November, 1995) represents the longest siege in the history of the world. Besides usual daily work, as the associate professor of Health education, Medical deontology and Medical informatics for the students of the Faculty of medicine, Faculty of dental medicine, Faculty of Pharmacy and Nursing college of University of Sarajevo, the author organized by himself and contributors, 10 scientific conferences in a sieged Sarajevo. All presented papers at those conferences are published in Proceedings abstract books, as the proof of continuing scientific work, in Sarajevo and other cities in B&H. Additionally, the author continued to publish, in that time, unique PubMed/MedLine indexed journal, - Medical Archives, (i.e. established in 1947) and, in 1993 formed a new journal named - "Acta Informatica Medica" (AIM) , as the Journal of the Bosnian Society of Medical informatics. Bosnian Society of Medical Informatics, thus became the first scientific association from Bosnia and Herzegovina, included in 1994, in the European Federation of Medical Informatics (EFMI) and the International Medical Informatics Assiciation (IMIA) , which was "miracle" from the besieged Sarajevo and war time result of aggression on Bosnia and Herzegovina. It should be noted that the importance of maintaining these academic gatherings, in the circumstances of war, was multifaceted. First of all, thanks to these meetings, the continuity of scientific meetings and activities in the besieged city of Sarajevo was not broken, as well as the continuity of scientific publication, which was crucial for the maintenance of the teaching staff at the university and, finally, in the expansion of the "scientific truth" about what happened in Sarajevo and B&H in these difficult times. All of this was critical

Laser-assisted drug delivery in dermatology: from animal models to clinical practice.

PubMed

Ali, Faisal R; Al-Niaimi, Firas

2016-02-01

Topical medicaments are the mainstay of the dermatologists' therapeutic arsenal. Laser-assisted drug delivery enhances the ability of topically applied medicaments to penetrate the skin. We discuss the mechanisms of laser-assisted drug delivery and animal models that have informed clinical practice. We review clinical studies that have employed laser-assisted drug delivery for a range of indications to date including non-melanoma skin cancer, vitiligo, scarring, vaccination, local anaesthesia, analgesia, viral warts, infantile haemangiomas and cosmetic uses. Studies thus far suggest that laser pre-treatment improves transepidermal absorption of topical agents and allows for a much deeper penetration of drugs than is possible with topical medicaments alone. This may allow more efficacious action of current treatments, such that conventional duration of treatment can be shortened or lower concentrations of active agents be used, potentially obviating side effects of treatment. The prospect of using laser technologies to facilitate transdermal vaccination and as an adjunct for inflammatory dermatoses and cosmetic indications remains in its infancy. As larger trials are published, involving greater numbers of patients and utilising various laser and topical medicament parameters, we will enhance our understanding of this nascent modality of treatment delivery.

Cachexia is a multifactorial syndrome, characterized by the loss of skeletal muscle mass and not fully reversible by nutritional support. Recent animal observations suggest that production of Activin A (ActA) and Myostatin (Mstn) by some tumors might contribute to cancer cachexia. Our goal was to investigate the role of ActA and Mstn in the development of the human cancer cachexia. The ACTICA study is a cross-sectional study, which prospectively enrolled patients from a tertiary-care center between January 2012 and March 2014. Subjects/Outcome Measures: One hundred fifty two patients with colorectal or lung cancer had clinical, nutritional and functional assessment. Body composition was measured by CT-scan, anthropometry, and bioimpedance. Plasma concentrations of ActA, Mstn, and Follistatin were determined. Cachexia was associated with reduced lean and fat mass (p < .01 and p < .001), reduced physical function, lower quality of life, and increased symptoms (QLQC30; p < .001). Anorexia (SNAQ score < 14) was more common in cachectic patients (CC) than in noncachectic patients (CNC) (p < .001). ActA concentrations in CC patients were higher than in CNC patients (+40%; p < .001) and were correlated positively with weight loss (R = 0.323; p < .001) and negatively with the SNAQ score (R = -0.225; p < .01). In contrast, Mstn concentrations were decreased in CC patients compared to CNC patients (-35%; p < .001). These results demonstrate an association between circulating concentrations of ActA and the presence of the anorexia/cachexia syndrome in cancer patients. Given the known muscle atrophic effects of ActA, our study suggests that increased circulating concentrations of ActA may contribute to the development of cachexia in cancer patients.

Influence of calcium hydroxide on the post-treatment pain in Endodontics: A systematic review

Introduction: Pain of endodontic origin has been a major concern to the patients and the clinicians for many years. Post-operative pain is associated with inflammation in the periradicular tissues caused by irritants egressing from root canal during treatment. It has been suggested that calcium hydroxide intra-canal medicament has pain-preventive properties because of its anti-microbial or tissue altering effects. Some dispute this and reasoned that calcium hydroxide may initiate or increase pain by inducing or increasing inflammation. Objective: To evaluate the effectiveness of calcium hydroxide in reducing the post-treatment pain when used as an intra-canal medicament Materials and Methods: The following databases were searched: PubMed CENTRAL (until July 2013), MEDLINE, and Cochrane Database of Systematic Reviews. Bibliographies of clinical studies and reviews identified in the electronic search were analyzed for studies published outside the electronically searched journals. The primary outcome measure was to evaluate the post-treatment pain reduction when calcium hydroxide is used as an intra-canal medicament in patients undergoing root canal therapy. Results: The reviews found some clinical evidence that calcium hydroxide is not very effective in reducing post-treatment pain when it is used alone, but its effectiveness can be increased when used in combination with other medicaments like chlorhexidine and camphorated monochlorophenol (CMCP). Conclusion: Even though calcium hydroxide is one of the most widely used intra-canal medicament due to its anti-microbial properties, there is no clear evidence of its effect on the post-treatment pain after the chemo-mechanical root canal preparation.

Background: An efficient antimicrobial agent action is required for a predetermined time period for absolute elimination of root canal microbes. Till date, there is limited or no data on the antimicrobial effect of octenidine as an intracanal medicament with chitosan (CTS) as a carrier against Candida albicans and Enterococcus faecalis. Aim: The aim of this microbiological study was to compare the antimicrobial efficacy of octenidine hydrochloride (OHC) and calcium hydroxide (Ca[OH]2) as intracanal medicaments, both independently and along with CTS as a carrier molecule against the common resistant endodontic pathogens. Materials and Methods: A total of 160 single-rooted anterior teeth were selected, root canal preparation was done, and teeth were divided into two groups and contaminated with C. albicans and E. faecalis, which were further divided into four test groups each according to intracanal medicaments used. CTS was used as a vehicle for OHC and Ca(OH)2 and antimicrobial assessment was performed on day 2 and day 7 following broth dilution method. Dentine samples were collected after each time interval, and the number of colony-forming units was determined. Results: All four medicaments used in this study showed antifungal and antibacterial activity that diminished from day 2 to day 7. Group I (OHC alone) and Group IV (Ca[OH]2 alone) showed significant antimicrobial activity against C. albicans and E. faecalis, respectively, than the other groups. Conclusion: A combination of OHC + CTS and Ca(OH)2+ CTS produced inferior results than that of the medicaments used alone. PMID:29599588

There is an ongoing discussion in the scientific community that even the leading scientific journals publish mainly research that is produced in the countries where these journals are based. We analysed data regarding the origin of publications in 11 leading general medical journals during the last 35 years: The Lancet, British Medical Journal, Journal of the American Medical Association, New England Journal of Medicine, Annals of Internal Medicine, Archives of Internal Medicine, American Journal of Medicine, Mayo Clinic Proceedings, Canadian Medical Association Journal, Medical Journal of Australia and Journal of Internal Medicine (previously called Acta Medica Scandinavica). Among the examined journals, The Lancet has been the most diverse regarding the origin of publications; in the period 1971-1975, 62.6% of its publications originated from the UK while the relevant figure dropped to 43.2% in the period 2001-2005 (19.4% decrease). During the period 2000-2005, the proportion of publications that originated from the country in which each one of the rest of the examined journals has been based ranged from 71.7% to 95.1%. This figure decreased by a proportion ranging from 10.9% to 19.4% for some major US- and UK-based medical journals during the 35-year study period. Our own interpretation of the findings of this study is that scientific journals will better serve the global scientific community as well as the public by adopting policies that increase the mixture of the origin of research that they publish, including work from scientists in developing countries, especially during the era we live.

To evaluate the effects of intracanal medicaments on endotoxins in root canals. Seventy-five freshly extracted maxillary incisors were used in this study. The crowns of teeth were sectioned near the CEJ in order to standardize the root length to 14 mm. The root canals were instrumented to an apical size #50 file and irrigated with 1% sodium hypochlorite solution and sterilized with 60Co gamma irradiation. Standardized suspension containing Escherichia coli endotoxin was inoculated into the 60 root canals. The specimens were randomly assigned to 5 groups (n=15), according to the intracanal medicament used: (G1) calcium hydroxide; (G2) polymyxin B; (G3) combination neomycin-polymyxin B-hydrocortisone; (G4) positive control (no intracanal medicament); (G5) negative control (no endotoxin and no intracanal medicament). After 7 days, the detoxification of endotoxin was evaluated by Limulus lysate assay and antibody production in B-lymphocytes culture. Groups 1, 2 and 5 presented the best results by Limulus lysate and were significantly different to groups 3 and 4 (p<0.05). Stimulation of antibodies production in cell culture by groups 1 and 6 was smaller and statistically different than groups 2, 3, 4 and 5 (p<0.05). Groups 2 and 5 induced a small increase in the antibodies production in relation to the groups 1 and 6. Groups 3 and 4 induced a significant increase of antibodies production (p<0.05). The calcium hydroxide and polymyxin B intracanal medicaments detoxified endotoxin in root canals and altered the properties of LPS to stimulate the antibody production by B-lymphocytes. The combination neomycin-polymyxin B-hydrocortisone did not detoxified endotoxin.

The results show remarkable improvements in the death registry coverage for both institutions, that amount to 97 or 98 per cent at the beginning of the 80's. Nevertheless, great differences can be observed between them regarding both structure and volume of deaths by sex and age."

This article describes a method for the detection and quantitation of cathine, pseudoephedrine, ephedrine, and methylephedrine in urine, using their deuterated analogues as internal standards and derivatization to form the corresponding trimethylsilyl derivatives after a simple liquid-liquid extraction. The study was designed to evaluate whether the urinary cutoff values set by the World Anti-Doping Agency for the banned ephedrines (cathine >5 microg/mL, ephedrine and methylephedrine >10 microg/mL) can be exceeded after the normal self-administration of common over-the-counter medicaments containing nonbanned ephedrines. The present method, after validation, has been applied on real urine samples obtained from 9 healthy volunteers taking different doses of over-the-counter preparations containing ephedrines. Results obtained from excretion studies show high interindividual differences in the urinary concentrations of both pseudoephedrine and cathine, not dependent on body weight or sex nor, in some instances, on the administered dose. The same typical therapeutic dose of pseudoephedrine (60 mg) produced a urinary concentration of more than 5 microg/mL for cathine and of more than 100 microg/mL for pseudoephedrine in 2 of 9 subjects only. When a dose of 120 mg was administered, cathine concentration exceeded 5 microg/mL in 4 of 7 subject, and also concentrations of pseudoephedrine above 100 microg/mL. After administration of 5 x 120 mg of pseudoephedrine (120 mg administered every 7 days for 5 weeks) to one of the subjects exceeding the urinary threshold values, the urinary concentration of cathine and pseudoephedrine exceeded 5 microg/mL (peak concentration 14.8 microg/mL) and 100 microg/mL (peak concentration 275 microg/mL), respectively. When the same subject took 180 mg of pseudoephedrine, the urinary concentration values were below 5 microg/mL for ephedrine and 100 microg/mL for pseudoephedrine.

Aim: The aim of the present study was to evaluate the bactericidal activity of propylene glycol, glycerine, polyethylene glycol 400 (PEG 400), and polyethylene glycol 1000 (PEG 1000) against selected microorganisms in vitro. Materials and Methods: Five vehicles, namely propylene glycol, glycerine, PEG 400, PEG 1000, and combination of propylene glycol with PEG 400, were tested for their bactericidal activity. The minimum bactericidal concentration was noted against four standard strains of organisms, i.e. Streptococcus mutans American Type Culture Collection (ATCC) 25175, Streptococcus mutans ATCC 12598, Enterococcus faecalis ATCC 35550, and Escherichia coli ATCC 25922, using broth dilution assay. Successful endodontic therapy depends upon thorough disinfection of root canals. In some refractory cases, routine endodontic therapy is not sufficient, so intracanal medicaments are used for proper disinfection of canals. Intracanal medicaments are dispensed with vehicles which aid in increased diffusion through the dentinal tubules and improve their efficacy. Among the various vehicles used, glycerine is easily available, whereas others like propylene glycol and polyethylene glycol have to be procured from appropriate sources. Also, these vehicles, being viscous, aid in sustained release of the medicaments and improve their handling properties. The most commonly used intracanal medicaments like calcium hydroxide are ineffective on many microorganisms, while most of the other medicaments like MTAD (Mixture of Tetracycline, an Acid, and a Detergent) and Triple Antibiotic Paste (TAP) consist of antibiotics which can lead to development of antibiotic resistance among microorganisms. Thus, in order to use safer and equally effective intracanal medicaments, newer alternatives like chlorhexidine gluconate, ozonized water, etc., are being explored. Similarly, the five vehicles mentioned above are being tested for their antimicrobial activity in this study. Results: All vehicles

The 14th volume of the Acta Historica Astronomiae is the Proceedings of a Colloquium International Relationships in Astronomy (in German) organised by the History of Astronomy Section of the Astronomische Gesellschaft held on September 18 in Lilienthal, Germany. The book contains 13 articles on astronomical topics covering the 19th and 20th centuries. The first paper is by Guenther Oestmann and deals with contemporary assessments of Johann Hieronymus Schroeter's (1745-1816) astronomical works and with later judgements of the scientific importance and significance of his observations as seen by astronomers and historians. This report is complemented by a second article on Schroeter's 25-ft reflector in Lilienthal near Bremen. To this end, author Felix Luehning has constructed a scale model of the telescope, and shows how the building of a model brings a deeper understanding of function and handling of this instrument. This brings us to a third paper on telescope building in Lilienthal: Hans-Joachim Leue describes the cooperation of Johann Hieronymus Schroeter and Johann Gottlieb Schrader in developing a white reflecting metal alloy for use as telescope mirror. The fourth article, by Klaus Schillinger, describes on the basis of archival documents the aquisition history of the Herschel telescopes, including telescope quality check, repair and building. Memorial sites referring to Wilhelm Olbers, Johann Hieronymus Schroeter, Friedrich Wilhelm Bessel and Carl Friedrich Gauss are described by Arno Langkavel in two walks outlined in the very last paper of this book. Peter Brosche, in the fifth paper, discusses the rediscovery of Ceres in December1801, a discovery that was the result of the combined efforts of a theoretician (Gauss) and an observer (Zach). Juergen Hamel's paper is based on previously unused archival sources and discusses the outstanding role played by H. C.

PubMed

2003-01-01

The 18th century was the 'Golden Age' of scientific academies and learned societies. The oldest national medical academy still in existence, the "Deutsche Akademie der Naturforscher" (Leopoldina), founded in 1652 in Schweinfurt as a private society, underwent steady growth after becoming an imperial institution with substantial privileges over the course of several decades. However, in comparison with other renowned academies in Europe, e.g. the English Royal Society or the French Académie des Sciences, it never gained a similar status due to the fact that its members lived far apart from each other and the seat of the academy was transferred to the residence of each new president, thus prohibiting the development of a geographical center. This paper focuses on the analysis of the central dialogue within the Leopoldina around 1750, the correspondence between the 6th president Andreas Elias Büchner (1701-1769), in Halle and the editor of the Leopoldina journal , the 13th Director Ephemeridum, Christoph Jacob Trew, in Nuremberg. Glancing at the four main topics of their long distance conversation - publishing the journal then called the '(Nova) Acta physico-medica', searching for new scientifically active members, improring the corporate identity amongst the Leopoldina members, enlarging the academy's library - it becomes clear that the Leopoldina profited greatly from the strong axis between Büchner and Trew. Their correspondence formed the center of a wide-spread network of letters through which the Leopoldina raised an active voice in the respublica litteraria, playing down Baroque curiosity and favoring a strong interest in rare and useful observations. Communication, interdisciplinarity and expertise formed the essential features of the Leopoldina's participation in the European natural scientific discourse.

Dental caries: strategies to control this preventable disease.

PubMed

Rugg-Gunn, Andrew

2013-11-01

To provide a brief commentary review of strategies to control dental caries. Dental decay is one of man's most prevalent diseases. In many counties, severity increased in parallel with importation of sugar, reaching its zenith about 1950s and 1960s. Since then, severity has declined in many countries, due to the wide use of fluoride especially in toothpaste, but dental caries remains a disease of medical, social and economic importance. Within the EU in 2011, the cost of dental treatment was estimated to be €79 billion. The pathogenesis is well understood: bacteria in dental plaque (biofilm) metabolise dietary sugars to acids which then dissolve dental enamel and dentine. Possible approaches to control caries development, therefore, involve: removal of plaque, reducing the acidogenic potential of plaque, reduction in sugar consumption, increasing the tooth's resistance to acid attack, and coating the tooth surface to form a barrier between plaque and enamel. At the present time, only three approaches are of practical importance: sugar control, fluoride, and fissure sealing. The evidence that dietary sugars are the main cause of dental caries is extensive, and comes from six types of study. Without sugar, caries would be negligible. Fluoride acts in several ways to aid caries prevention. Ways of delivering fluoride can be classed as: 'automatic', 'home care' and 'professional care': the most important of these are discussed in detail in four articles in this issue of the Acta Medica Academica. Dental caries is preventable - individuals, communities and countries need strategies to achieve this. Copyright © 2013 by Academy of Sciences and Arts of Bosnia and Herzegovina.

Transmission of traditional knowledge over time and across culturally and historically related territories is an important topic in ethnopharmacology. Here, we contribute to this knowledge by analysing data on medicinal uses in two neighbouring areas of the Western Mediterranean in relation to a historical text that has been scarcely mentioned in historical studies despite its interest. This paper discusses the sharing of popular knowledge on the medicinal uses of plants between eastern Morocco and eastern Andalusia (Spain), focusing on one of the most useful plant families in the Mediterranean area: Lamiaceae. Moreover, we used the classical work of Ibn al-Baytar (13th century CE) The Compendium of Simple Medicaments and Foods as a basis to contrast the possible link of this information, analysing the influence of this historical text on current popular tradition of medicinal plant use in both territories. For data collection, we performed ethnobotanical field research in the eastern part of Morocco, recording current medicinal uses for the Lamiaceae. In addition, we systematically reviewed the ethnobotanical literature from eastern Andalusia, developing a database. We investigated the possible historical link of the shared uses and included in this database the information from Ibn al-Baytar's Compendium. To compare the similarity and diversity of the data, we used Jaccard's similarity index. Our field work provided ethnobotanical information for 14 Lamiaceae species with 95 medicinal uses, serving to treat 13 different pathological groups. Of the total uses recorded in Morocco, 30.5% were shared by eastern Andalusia and found in Ibn al-Baytar's work. There was a higher similarity when comparing current uses of the geographically close territories of eastern Morocco and eastern Andalucía (64%) than for eastern Morocco and this historical text (43%). On the other hand, coincidences between current uses in eastern Andalusia and the ones related in the Compendium

Due to the global rise in the use of traditional Chinese medicine (TCM), Chinese materia medica (medicinal materials, or CMM) are giving cause for concern over their evidence base, safety/possible toxicity, questionable quality and use of endangered species of both animals and plants. However, little if anything is actually known about the range of species used to produce CMM used in Europe and even in China. This study represents the first attempt to identify and compare the most important CMM used in both regions, to begin the process of assessing the risks to public health and possible future benefits. Data were collected from a convenience sample of TCM practitioners in the EU and mainland China, using a paper/online survey. Among other questions, respondents were asked (1) which conditions they most commonly treated using CMM and the likelihood of them using herbal manufactured products and decoctions in addition to raw herbs; (2) the perceived frequency with which they observed adverse events to CMM; (3) the frequency and reasons for use of 1 herbal formula and 6 specific individual herbs; (4) an open question about other CMM they used, including materials of non-plant origin. Data were entered into PASW statistics package and analysed using frequency tables, cross-tabulations and chi-squared tests to compare EU and Chinese results. From a total of 747 useable questionnaires (420 from China, 327 from the EU) of those responding from the EU, TCM was generally more commonly used for obstetric/gynaecological and dermatological conditions, compared to neurological and gastrointestinal diseases in China. Disorders treated by Chinese practitioners were more varied, and often more serious, than those treated by their European counterparts, and the range of materials used in China was wider. The potential for toxicity was not high in either region, but although greater in China due to the use of more potent CMM, the incidence of side effects was perceived to be

2012-01-01

After being indexed in 2006 in EMBASE/Excerpta Medica and Scopus, and later in Science Citation Index Expanded and Journal Citation Reports/Science Edition citation databases, Biochemia Medica launched a new web page and online manuscript submission system in 2010, and celebrated its first Impact Factor in the same year. Now, starting from the end of the 2011, the journal will also be indexed in PubMed/Medline, and this will contribute to increase the journal’s exposure and accessibility worldwide. This is an important breakthrough, which is expected to further increase the popularity of the journal, as well as the submission rate and citations. Although several tools are currently available as Web resources to retrieve scientific articles, whose functioning and basic criteria are thought to be rather similar, the functionality, coverage, notoriety and prominence may differ widely. The recent indexing of Biochemia Medica in PubMed/Medline has thereby given us the opportunity to provide a timely update on biomedical research platforms, their relationship with article submissions and journal rankings.

Veterinary pharmacology: history, current status and future prospects.

PubMed

Lees, P; Fink-Gremmels, J; Toutain, P L

2013-04-01

Veterinary therapeutics, based on the art of Materia Medica, has been practised for countless centuries, but the science of veterinary pharmacology is of very recent origin. This review traces the contribution of Materia Medica to veterinary therapeutics from the Egyptian period through to the Age of Enlightenment. The first tentative steps in the development of the science of veterinary pharmacology were taken in the 18th century, but it was not until the mid 20th century that the science replaced the art of Materia Medica. This review traces the 20th century developments in veterinary pharmacology, with emphasis on the explosion of knowledge in the 35 year period to 2010. The range of factors which have influenced the current status of the discipline are reviewed. Future developments are considered from the perspectives of what might be regarded as desirable and those innovations that might be anticipated. We end with words of encouragement for young colleagues intent upon pursuing a career in veterinary pharmacology. © 2013 Blackwell Publishing Ltd.

Cardiovascular aspects of geriatric medicines in traditional Persian medicine; a review of phytochemistry and pharmacology.

PubMed

Zarshenas, Mohammad M; Jamshidi, Sahar; Zargaran, Arman

2016-10-15

Geriatrics are a group of patients over 65 years and with multiple comorbidities and different functional impairments. Apart from decline in body mass, presence of exhaustion and general fatigue, an aged person may also suffer from various disorders. Approximately, around 30% of geriatric subjects have significant cardiovascular ailments. Apart from the intensive management of cardiovascular aspects in elderly, monitoring of the complementary cardiac medicine in those people should be received more attention. There are many management lines for a cardio-geriatric condition in Traditional Persian Medicine (TPM). Accordingly, this paper aimed to deal with those medicaments as well as evidence-based clinical aspects and phytochemistry. By searching through main pharmaceutical manuscripts of Persian medicine during 10th-18th centuries (A.D.), concurrently, natural medicines for geriatrics and remedies for cardiovascular ailments were derived. On the other side, related phytochemical and pharmacological aspects of those remedies were highlighted. In all, 38 cardiovascular and 34 geriatric medicaments were found in those manuscripts. Antihyperlipidemic and cholesterol lowering activities of those medicines were the most reported activities in current medicine. However, other pharmacological reports were related to hypotensive, coagulant, cardio-protective and cardiotonic activities. In regard of the chemical composition, medicaments were mainly of polyphenols and flavonoids and also most of the employed extracts and fractions were yielded from polar or semi-polar solvents. With reference to these findings, flavonoid-rich medicaments from Persian medicine may be selected as considerable herbs for geriatrics with cardiovascular ailments. Copyright © 2016 Elsevier GmbH.

Regulation, circulation and distribution of penicillin in Portugal (1944-1954).

PubMed

Bell, Victoria; Rui Pita, João; Pereira, Ana Leonor

Portugal did not participate in World War II but was one of the first countries in the world to receive penicillin for civilian use. The Portuguese Red Cross began to import the antibiotic from the United States of America in 1944 and appointed a controlling committee to oversee its distribution, due to the small amount available. In 1945, as world production increased, penicillin began to be distributed through the normal channels. An important role in its regulation was played by the official department responsible for controlling pharmaceutical and chemical products in Portugal, the Comissão Reguladora dos Produtos Químicos e Farmacêuticos (Regulatory Committee for Chemical and Pharmaceutical Products). Penicillin was imported as a raw material from 1947 and the first medicaments containing penicillin, prepared in Portugal, were released into the commercial circuit in 1948. A laboratory had been established in 1942 by the Comissão Reguladora for the analytical verification of medicaments and medicinal products with the aim of certifying their quality and minimizing the number of products with no attested therapeutic efficacy. The number of medicaments analysed by this laboratory increased substantially from 72 in the year of its foundation (1942) to 2478 in 1954, including, after 1948, medicaments containing penicillin. The aim of the present paper was to elucidate the role of the Comissão Reguladora dos Produtos Químicos e Farmacêuticos in regulating and controlling the distribution of penicillin in Portugal during the 1940s and 1950s.

This study is based on 25 well documented reports of cases which responded well to treatment with Petroleum. Materia medica data were compared with results in contemporary clinical practice. Many patients had characteristic skin problems; children often had recurrent or chronic upper respiratory tract problems. The most prominent mental feature is a quiet, withdrawn or stubborn disposition. The mental symptoms may be difficult to recognise. Detailed documentation in daily practice can be helpful for preserving data of the effect of a medicine; confirmation of statements given in materia medica; improving understanding of homeopathic medicines and differentiating the indications for medicines.

Among the issues of medical exchanges, medicaments are more often encountered than medical issues, based on ancient Chinese literatures, early in the Han-Jin Dynasties, Thailand, Malaysia, Indonesia, and Brunei had exchanges with China, also in Sui-Tang Dynasties. In the Song-Yuan Dynasties, ancient Singapore and the Philippines also incorporated in exchanges of medicament and goods. In the Ming-Qing dynasties, these 6 Asian countries had even more close contact with China, especially in trades and medical exchanges among the masses, carried out in a large scale thus, promoting the advent and development of TCM in Asiana Regions.

Sources of sensitization, cross-reactions, and occupational sensitization to topical anaesthetics among general dermatology patients.

PubMed

Jussi, Liippo; Lammintausta, Kaija

2009-03-01

Contact sensitization to local anaesthetics is often from topical medicaments. Occupational sensitization to topical anaesthetics may occur in certain occupations. The aim of the study was to analyse the occurrence of contact sensitization to topical anaesthetics in general dermatology patients. Patch testing with topical anaesthetics was carried out in 620 patients. Possible sources of sensitization and the clinical histories of the patients are analysed. Positive patch test reactions to one or more topical anaesthetics were seen in 25/620 patients. Dibucaine reactions were most common (20/25), and lidocaine sensitization was seen in two patients. Six patients had reactions to ester-type and/or amide-type anaesthetics concurrently. Local preparations for perianal conditions were the most common sensitizers. One patient had developed occupational sensitization to procaine with multiple cross-reactions and with concurrent penicillin sensitization from procaine penicillin. Dibucaine-containing perianal medicaments are the major source of contact sensitization to topical anaesthetics. Although sensitization to multiple anaesthetics can be seen, cross-reactions are possible. Contact sensitization to lidocaine is not common, and possible cross-reactions should be determined when reactions to lidocaine are seen. Occupational procaine sensitization from veterinary medicaments is a risk among animal workers.

Iontophoresis significantly increases the trans-dentinal delivery of osteoprotegerin, alendronate, and calcitonin.

2007-10-01

The purpose of this study was to evaluate the delivery of alendronate, calcitonin, and osteoprotegerin (OPG) through human dentin by both diffusion and iontophoresis for the potential treatment of invasive cervical resorption. Radiolabeled alendronate, calcitonin, and OPG were added to the top of a split chamber device that contained 1-mm thick dentin disks devoid of a smear layer. Transdentinal movement of medicaments by either random diffusion or application of an iontophoretic current was measured by analysis of gamma emission of effluent fractions. In addition, calcitonin delivery was evaluated at differing magnitudes of current (0-4 mA) by using the aforementioned chamber. Diffusion of all 3 medicaments was minimal. In contrast, the application of a 3-mA iontophoretic gradient significantly increased delivery for all 3 compounds at 10-, 20-, and 30-minute intervals. In addition, a linear increase in permeability was seen for calcitonin as milliamperes were increased from 0 to 4 (r = 0.947), with more than a 100-fold increase in delivery observed with iontophoresis. Delivery of the tested medicaments by using iontophoresis might prove to be a useful technique for treatment of invasive cervical resorption.

[The effects of Cardiodoron on cardio-respiratory coordination--a literature review].

PubMed

Cysarz, D; Heckmann, C; Kümmell, H C

2002-10-01

In healthy subjects self-regulation of the organism establishes the order of rhythmical functions. This self-regulation is altered in patients suffering from idiopathic orthostatic syndrome resulting from disturbances of functional aspects only. Thus the cardio-respiratory coordination, which may serve as the representative of the order of rhythmical functions, is modified. In the case of idiopathic orthostatic syndrome the anthroposophic medicine offers the medicament Cardiodoron(r). Does it stimulate self-regulation in order to normalise the cardio-respiratory coordination? This claim is analysed by a systematic review of the literature. Only those publications were considered where the cardio-respiratory coordination was analysed in studies with patients or healthy subjects. The methods of the studies with patients and healthy subjects vary strongly. Nevertheless, a normalisation of the cardio-respiratory coordination could be found in studies with patients suffering from idiopathic orthostatic syndrome as well as in studies with healthy subjects. The studies show that the use of the medicament results in a normalisation of the cardiorespiratory coordination. By stimulating the self-regulation the medicament leads to an improvement of the order of rhythmical functions in the human organism. Copyright 2002 S. Karger GmbH, Freiburg

[Fake malaria drugs].

2009-03-02

The literature on fake medicaments is sparse, even if approximately 15% of all medicaments are fake, a figure that for antimalarials in particular reaches 50% in parts of Africa and Asia. Sub-standard and fake medicines deplete the public's confidence in health systems, health professionals and in the pharmaceutical industry - and increase the risk that resistance develops. For a traveller coming from a rich Western country, choosing to buy e.g. preventive antimalarials over the internet or in poor malaria-endemic areas, the consequences may be fatal. International trade-, control- and police-collaboration is needed to manage the problem, as is the fight against poverty and poor governance.

An Empire's Extract: Chemical Manipulations of Cinchona Bark in the Eighteenth-Century Spanish Atlantic World.

Crawford, Matthew James

2014-01-01

In 1790, the Spanish Crown sent a "botanist-chemist" to South America to implement production of a chemical extract made from cinchona bark, a botanical medicament from the Andes used throughout the Atlantic World to treat malarial fevers. Even though the botanist-chemist's efforts to produce the extract failed, this episode offers important insight into the role of chemistry in the early modern Atlantic World. Well before the Spanish Crown tried to make it a tool of empire, chemistry provided a vital set of techniques that circulated among a variety of healers, who used such techniques to make botanical medicaments useful and intelligible in new ways.

The Mental Capacity Act--a balance between protection and liberty.

PubMed

Walters, Thomas Paul

The stated aim of the Mental Capacity Act is to provide greater protection to those who may lose their mental capacities, particularly in terms of informed consent, patient affairs, advanced decisions and research. This article attempts to explore this new statute by way of examining the scope to which the Act departs from the previous Common Law. Three key themes are identified within this new Act, which differentiate it from Common Law: patients' best interests, which is paramount to any care or treatment; proxy consent, whereby donees can now be appointed to take charge of medical decisions; and advanced directives, where so-called living wills can be enforced provided that they are specific, written, signed and witnessed. However, upon examining the statute it appears that rather than increasing patient autonomy and self-determination, evidence suggests that power is still being held by the medical profession. Whether patients have full autonomy or not, the main issue could be how to strike an effective and workable balance between protection and liberty.

The Metalloprotease Mpl Supports Listeria monocytogenes Dissemination through Resolution of Membrane Protrusions into Vacuoles

PubMed Central

Alvarez, Diego E.

2016-01-01

Listeria monocytogenes is an intracellular pathogen that disseminates within the intestinal epithelium through acquisition of actin-based motility and formation of plasma membrane protrusions that project into adjacent cells. The resolution of membrane protrusions into vacuoles from which the pathogen escapes results in bacterial spread from cell to cell. This dissemination process relies on the mlp-actA-plcB operon, which encodes ActA, a bacterial nucleation-promoting factor that mediates actin-based motility, and PlcB, a phospholipase that mediates vacuole escape. Here we investigated the role of the metalloprotease Mpl in the dissemination process. In agreement with previous findings showing that Mpl is required for PlcB activation, infection of epithelial cells with the ΔplcB or Δmpl strains resulted in the formation of small infection foci. As expected, the ΔplcB strain displayed a strong defect in vacuole escape. However, the Δmpl strain showed an unexpected defect in the resolution of protrusions into vacuoles, in addition to the expected but mild defect in vacuole escape. The Δmpl strain displayed increased levels of ActA on the bacterial surface in protrusions. We mapped an Mpl-dependent processing site in ActA between amino acid residues 207 to 238. Similar to the Δmpl strain, the ΔactA207–238 strain displayed increased levels of ActA on the bacterial surface in protrusions. Although the ΔactA207–238 strain displayed wild-type actin-based motility, it formed small infection foci and failed to resolve protrusions into vacuoles. We propose that, in addition to its role in PlcB processing and vacuole escape, the metalloprotease Mpl is required for ActA processing and protrusion resolution. PMID:27068088

Teeth with immature apex are managed by establishing an apical plug using various materials and techniques. However, the use of previously placed intracanal medicament may affect the sealing ability of permanent filling material used as an apical plug. To evaluate the effect of removal of previously placed Calcium Hydroxide, Chlorhexidine Digluconate and Camphorated Monochlorophenol as an intracanal medicament on the sealing ability of the Biodentine as an apical plug. A total of 72 recently extracted human permanent teeth with single root were selected and stored in saline at room temperature. The crown portion of each tooth was removed at the level of cemento enamel junction; 14mm root length was taken as standard length. All the roots were submerged in 20% sulphuric acid up to 3 mm from the apex, for four days for root resorption. One sample was cut longitudinally to look for root resorption under stereo microscope. The canal preparation was done; the roots were kept in moist gauze after instrumentation. A total of 71 roots were randomly divided into three groups. GROUP 1:Calcium hydroxide paste, GROUP 2: Chlorhexidine digluconate, GROUP 3: Camphorated Monochlorophenol (CMCP). The medicaments were removed with stainless steel hand files and 0.5% sodium hypochlorite irrigation. After removal of medicament Biodentine was placed in apical third of resorbed roots and the remaining portion of the canals was filled with gutta-percha. All the 71 roots were analysed with fluid filtration method for evaluating microleakage. Comparing all the three groups statistically there was no significant difference. The mean values were found more for group 1 followed by group 2 & 3. All the groups showed microleakage. Calcium hydroxide showed the maximum microleakage followed by Chlorhexidine digluconate and least with CMCP.

Revascularization outcome depends on microbial elimination because apical repair will not happen in the presence of infected tissues. This study evaluated the microbial composition of traumatized immature teeth and assessed their reduction during different stages of the revascularization procedures performed with 2 intracanal medicaments. Fifteen patients (7-17 years old) with immature teeth were submitted to the revascularization procedures; they were divided into 2 groups according to the intracanal medicament used: TAP group (n = 7), medicated with a triple antibiotic paste, and CHP group (n = 8), dressed with calcium hydroxide + 2% chlorhexidine gel. Samples were taken before any treatment (S1), after irrigation with 6% NaOCl (S2), after irrigation with 2% chlorhexidine (S3), after intracanal dressing (S4), and after 17% EDTA irrigation (S5). Cultivable bacteria recovered from the 5 stages were counted and identified by means of polymerase chain reaction assay (16S rRNA). Both groups had colony-forming unit counts significantly reduced after S2 (P < .05); however, no significant difference was found between the irrigants (S2 and S3, P = .99). No difference in bacteria counts was found between the intracanal medicaments used (P = .95). The most prevalent bacteria detected were Actinomyces naeslundii (66.67%), followed by Porphyromonas endodontalis, Parvimonas micra, and Fusobacterium nucleatum, which were detected in 33.34% of the root canals. An average of 2.13 species per canal was found, and no statistical correlation was observed between bacterial species and clinical/radiographic features. The microbial profile of infected immature teeth is similar to that of primarily infected permanent teeth. The greatest bacterial reduction was promoted by the irrigation solutions. The revascularization protocols that used the tested intracanal medicaments were efficient in reducing viable bacteria in necrotic immature teeth. Copyright © 2014 American Association of

Actin-based motility allows Listeria monocytogenes to avoid autophagy in the macrophage cytosol.

PubMed

Cheng, Mandy I; Chen, Chen; Engström, Patrik; Portnoy, Daniel A; Mitchell, Gabriel

Listeria monocytogenes grows in the host cytosol and uses the surface protein ActA to promote actin polymerisation and mediate actin-based motility. ActA, along with two secreted bacterial phospholipases C, also mediates avoidance from autophagy, a degradative process that targets intracellular microbes. Although it is known that ActA prevents autophagic recognition of L. monocytogenes in epithelial cells by masking the bacterial surface with host factors, the relative roles of actin polymerisation and actin-based motility in autophagy avoidance are unclear in macrophages. Using pharmacological inhibition of actin polymerisation and a collection of actA mutants, we found that actin polymerisation prevented the colocalisation of L. monocytogenes with polyubiquitin, the autophagy receptor p62, and the autophagy protein LC3 during macrophage infection. In addition, the ability of L. monocytogenes to stimulate actin polymerisation promoted autophagy avoidance and growth in macrophages in the absence of phospholipases C. Time-lapse microscopy using green fluorescent protein-LC3 macrophages and a probe for filamentous actin showed that bacteria undergoing actin-based motility moved away from LC3-positive membranes. Collectively, these results suggested that although actin polymerisation protects the bacterial surface from autophagic recognition, actin-based motility allows escape of L. monocytogenes from autophagic membranes in the macrophage cytosol. © 2018 John Wiley & Sons Ltd.

In 1996, the World Food Summit reaffirmed the inalienable right that each person across the globe has to access safe, adequate and nutritious food. At that time a goal was established to reduce by half the number of undernourished persons worldwide by 2015, in other words the year that we are now commencing. Different countries and organisations considered the necessity of reaching consensus and developing indicators for measuring household food insecurity. The availability of a simple but evidence-based measurement method to identify nutritionally at-risk population groups constitutes an essential instrument for implementing strategies that effectively address relevant key issues.

Potential fluoride toxicity from oral medicaments: A review.

PubMed

Ullah, Rizwan; Zafar, Muhammad Sohail; Shahani, Nazish

2017-08-01

The beneficial effects of fluoride on human oral health are well studied. There are numerous studies demonstrating that a small amount of fluoride delivered to the oral cavity decreases the prevalence of dental decay and results in stronger teeth and bones. However, ingestion of fluoride more than the recommended limit leads to toxicity and adverse effects. In order to update our understanding of fluoride and its potential toxicity, we have described the mechanisms of fluoride metabolism, toxic effects, and management of fluoride toxicity. The main aim of this review is to highlight the potential adverse effects of fluoride overdose and poorly understood toxicity. In addition, the related clinical significance of fluoride overdose and toxicity has been discussed.

Aspects of Solvent Chemistry for Calcium Hydroxide Medicaments

PubMed Central

Athanassiadis, Basil

Calcium hydroxide pastes have been used in endodontics since 1947. Most current calcium hydroxide endodontic pastes use water as the vehicle, which limits the dissolution of calcium hydroxide that can be achieved and, thereby, the maximum pH that can be achieved within the root canal system. Using polyethylene glycol as a solvent, rather than water, can achieve an increase in hydroxyl ions release compared to water or saline. By adopting non-aqueous solvents such as the polyethylene glycols (PEG), greater dissolution and faster hydroxyl ion release can be achieved, leading to enhanced antimicrobial actions, and other improvements in performance and biocompatibility.

During foetal development, neonatal period and childhood, the immune system is constantly maturing. In the foetus, infection responsiveness is low and associates with spontaneous abortion. During the neonatal period, the infection response shifts towards a more pro-inflammatory response. The immune system of the newborn acquires adaptive features as a result of exposure to microbes. The development of the human immune system is a continuous process where both accelerated and retarded development is deleterious. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

We sought to explore the relationship between vital capacity and obesity among university students in China. A cross-sectional study was designed to collect the routine health screening data for university students in 2013. The height, weight and force vital capacity of students were measured, and BMI was calculated with height and weight, so as to estimate the relationship between force vital capacity and obesity. Based on Working Group on Obesity references in China, obesity has a higher force vital capacity in both male and female university students. No correlation was found between vital capacity and BMI. obesity may have effect on pulmonary function among university students, which is a reference for further epidemic study.

Instinctive behaviours have evolved favouring the mother-infant dyad based on fundamental processes of neurological development, including oral tactile imprinting and latchment. Latchment is the first stage of emotional development based on the successful achievement of biological imprinting. The mechanisms underpinning imprinting are identified and the evolutionary benefits discussed. It is proposed that the oral tactile imprint to the breast is a keystone for optimal latchment and breastfeeding, promoting evolutionary success. ©2015 The Authors.

2018-03-07

To investigate the antibacterial activity of a novel intracanal medicament, iRoot FM, against Porphyromonas endodontalis and its effects on the proliferation and osteo-/odontogenic differentiation of stem cells from apical papilla (SCAP). The agar diffusion test was used to compare the antimicrobial efficacy of iRoot FM with two traditional intracanal medicaments, calcium hydroxide [Ca(OH) 2 ] and triple antibiotic paste (TAP). The CCK-8 assay was used to assess the proliferation rate of SCAP when exposed to the three intracanal medicaments. The expression levels of ALP and DMP-1 and the capacity to form mineralized nodules were used to evaluate the osteo-/odontogenic differentiation of SCAP, as assessed by real-time PCR, Western blotting and alizarin red S staining. Data were statistically analysed with one-way analysis of variance (anova), and comparisons between each of two groups were analysed by the least significance difference method. P values less than 0.05 were considered statistically significant. The zone of inhibition against P. endodontalis produced by iRoot FM was 20.74 ± 4.35 mm, whilst the zones of inhibition of Ca(OH) 2 and TAP were 24.89 ± 3.84 mm and 34.51 ± 1.20 mm. The antibacterial capacity of iRoot FM was similar to that of Ca(OH) 2 (P > 0.05). SCAP, cultured in conditioned medium with iRoot FM, was associated with greater proliferation and osteo-/odontogenic differentiation capacity than those cultured in conditioned medium with Ca(OH) 2 and TAP (P < 0.05). Moreover, iRoot FM had no negative effects on the proliferation rate of SCAP. iRoot FM exhibited excellent antibacterial activity against P. endodontalis and could improve the proliferation and differentiation of SCAP. The findings provide evidence that iRoot FM has potential as an intracanal medicament for endodontic procedures in immature permanent teeth. © 2018 International Endodontic Journal.

Evaluation of triple antibiotic paste removal by different irrigation procedures.

Regenerative endodontics aims to re-establish a functional pulp-dentin complex. First, the root canal system is disinfected primarily by irrigants and medicaments. Triple antibiotic paste (TAP), a commonly used intracanal medicament, has been shown to be directly toxic to stem cells at concentrations greater than 0.1 g/mL. Thus, its complete removal is a crucial step in regenerative endodontic procedures. We hypothesized that currently used irrigation techniques do not completely remove TAP from root canal system. TAP was radiolabeled by the incorporation of I(125), and calcium hydroxide (Ultracal; Ultradent, South Jordan, UT) was radiolabeled with Ca(45). The intracanal medicaments were placed into standardized human root segments and incubated for 28 days at 37°C. Then, canals were irrigated with EndoActivator (Dentsply, Tulsa, OK), passive ultrasonic irrigation, EndoVac (SybronEndo, Coppell, TX), or a syringe/Max-i-Probe needle (Dentsply Rinn, Elgin, IL) using a standardized irrigation protocol in a closed system. Radioactivity levels (counts per minute values) were measured for each tooth before and after the irrigation protocols. Furthermore, the canals were sequentially enlarged and dentin samples collected and evaluated for radioactivity. Data were analyzed with analysis of variance and Bonferroni post hoc testing (P < .05). Approximately 88% of the TAP was retained in the root canal system regardless of the irrigation technique used (no difference among groups). Furthermore, approximately 50% of the radiolabeled TAP was present circumferentially up to 350 μm within the dentin. Conversely, up to 98% of the radiolabeled intracanal calcium hydroxide was removed, and most residual medicament was found present in the initial 50 μm of dentin. Current irrigation techniques do not effectively remove TAP from root canal systems, possibly because of its penetration and binding into dentin. However, calcium hydroxide is effectively removed with significant less

We used next-generation sequencing to identify somatic alterations in multiple metastatic sites from an “exceptional responder” lung adenocarcinoma patient during his 7-yr course of ERBB2-directed therapies. The degree of heterogeneity was unprecedented, with ∼1% similarity between somatic alterations of the lung and lymph nodes. One novel translocation, PLAG1-ACTA2, present in both sites, up-regulated ACTA2 expression. ERBB2, the predominant driver oncogene, was amplified in both sites, more pronounced in the lung, and harbored an L869R mutation in the lymph node. Functional studies showed increased proliferation, migration, metastasis, and resistance to ERBB2-directed therapy because of L869R mutation and increased migration because of ACTA2 overexpression. Within the lung, a nonfunctional CDK12, due to a novel G879V mutation, correlated with down-regulation of DNA damage response genes, causing genomic instability, and sensitivity to chemotherapy. We propose a model whereby a subclone metastasized early from the primary site and evolved independently in lymph nodes. PMID:27900369

Les parametres de procede ainsi que les proprietes de la solution a electrofiler ont ete optimises dans le but de creer des fibres de PNVCL lisses, continues et sans perles. Des solutions du melange (PNVCL) / (PCL) ont ete ensuite preparees en suivant quatre methodes differentes de preparation. Ces methodes se basent sur l'emploi de solvants distincts, eau distillee et chloroforme, avec differentes concentrations de polymere, 42wt% et 30wt% respectivement. Ces solutions ont ete electrofilees en utilisant les parametres de procede qui correspondaient aux meilleures conditions pour l'electrofilage du PNVCL. Ensuite, le ketophofene, un medicament hydrophobe, a ete ajoute au PNVCL et au melange PNVCL/PCL avant l'electrofilage afin d'etudier la capacite des fibres de PNVCL et de melanges de retenir le medicament hydrophobe et a en faire sa liberation. Enfin, des fibres noyau-enveloppes ont ete obtenues par electrofilage coaxial, en utilisant une solution aqueuse du melange PNVCL/PCL (42 wt%) pour l'enveloppe et une solution aqueuse du PEG (30 wt%) pour le noyau.

Sedentary behavior and physical exercise seem to influence the nutritional status of the population independently. In this sense, sedentary behavior is associated inversely with healthy eating patterns and directly with BMI, body fat, risk of chronic diseases and psychological problems. By contrast, regular exercise is associated with a healthier diet and health benefits as the prevention or reduction of excess weight and disease prevention.

To improve the nutritional status and health of the population would be advisable to increase non-sedentary behaviors and decrease the time spent in front of the screen.

In 2011, the Nobel Prize in Physiology and Medicine was rewarded, in part, for research on the Drosophila immune response. The research described the role of the Drosophila Toll receptor in antifungal resistance, and the subsequent characterization of Toll-like receptors in mammals reshaped our understanding of the immune system. This review summarizes the potential of the Drosophila model and describes the path that has lead Drosophila to become an important model to study immunity. Drosophila melanogaster has been one of the most fruitful models to study innate immunity. © 2012 The Author(s)/Acta Paediatrica © 2012 Foundation Acta Paediatrica.

For a close follow-up of large groups of pacemaker patients and for evaluation of long term pacing on a reliable statistical basis, many pacemaker centers in the world are now using computer systems. A patient data system with structured display records, designed to give complete, comprehensive and surveyable information and which are immediately retrievable 24 hours a day, on display or printed sets, seems to offer an ideal solution. The pacemaker clinic at the Regional Hospital of Udine has adopted this type of system. The clinic in linked to a live, on-line patient data system (G/3, Informatica Friuli-Venezia Giulia). The input and retrieval of information are made through a conventional keyboard. The input formats have fixed headings with coded alternatives and a limited space for comments in free text. The computer edits the coded information to surveyable reviews. Searches can be made on coded information and data of interest.

characteristics of the aerobatic parabolic flights are different from the ones corresponding to the big Airbus-300 of Novespace-CNES-ESA aircraft. In this case, the two episodes of hypergravity reach 1.8g for 3 seconds with 20-25 seconds of low gravity in between whereas the small aerobatic plane reaches 3g level during roughly 2.5 seconds and 8 seconds period of low gravity. This means that the present potential alterations of the human body are more aggressive but also faster. [1] Y. Kawai, M. Doi, A. Setogawa, R. Shimoyama, K. Ueda, Y. Asai, K.

The ecological agriculture of traditional Chinese medicine (TCM) is generally acknowledged as the most advanced agricultural mode. However, it's still a doubt whether ecological agriculture could be widely applied in TCM agriculture. In this study, we first analyze both the differences and relationships between ecological and organic agriculture, which suggesting that ecological agriculture does not need all the inputs as traditional agriculture. After introducing the situation of ecological agriculture from all across the world, we analyze the differences and characteristics between ecological and chemical agricultures. Considered with the big challenge caused by chemical agriculture, we pointed out that ecological agriculture could definitely replace chemical agriculture. Last but not the least, combined with the situation and problems of Chinese agriculture, we analyze the distinctive advantages of TCM ecological agriculture from 3 aspects as its unique quality characteristics, its unique habitat requirements in production and its unique application and market characteristics, respectively. In conclusion, ecological agriculture is the straight way of TCM agriculture. Copyright© by the Chinese Pharmaceutical Association.

From antiquity up into the 20th century tertian and quartan malaria which are caused by the parasites Plasmodium vivax and Plasmodium malariae were widespread in Central Europe. Hundreds of different remedies against malaria can be found in herbals from the Renaissance. To document and discuss from a modern pharmacological viewpoint the old remedies described in eight 16th and 17th century herbals written in German. Eight of the most important herbals of the 16th and 17th century including Bock (1577), Fuchs (1543), Matthiolus (1590), Lonicerus (1560), Brunfels (1532), Zwinger (1696), and Tabernaemontanus (1591 and 1678) were searched for terms related to malaria, and documented plants and recipes described for its treatment. Additionally the overlapping of these remedies with those in De Materia Medica by the Greek physician Dioscorides was studied. Three hundred and fourteen taxa were identified in the herbals for this indication. Recent pharmacological data was found for just 5% of them. The influence of De Materia Medica was shown to be negligible with only 3.5% of the remedies in common. European Renaissance herbals may be a valuable source of information for the selection of plants for focussed antiplasmodial screening programmes, but have received only little scientific attention. Antimalarial remedies from these herbals must be viewed as independent sources of knowledge separate from Dioscorides' De Materia Medica. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Ethno-diversity within current ethno-pharmacology as part of Israeli traditional medicine – A review

2006-01-01

The Holy Land has absorbed millions of immigrants in recent centuries: Jews from East and West, Druze, Circassians, Muslim and Christian Arabs. The land is unique and diverse in geographical location and ethnic groups, and also in its cultural characteristics, including traditional medicine and use of materia medica. However, these traditions have waned over the years. The young state of Israel adopted a "melting pot" approach to fashion Jews from all over the world into Israelis. The traditional medicine and materia medica of different ethnic groups (Yemenite, Iranian, and Iraqi Jews) are reviewed in this paper, as well as the ethno-botanical survey (first conducted in the 1980s, covering Bedouins, Druze, Circassians, and Muslim and Christian Arabs), and the matching ethno-pharmacological survey (conducted in the late 1990s) covering the medicines sold in stores. Present-day healers are usually not young and are believed to be the end of the chain of traditional medical knowledge. The ethno-diversity of Israel is becoming blurred; modernity prevails, and ethnic characteristics are fading. The characteristic lines of traditional medicine and materia medica have hardly lasted three generations. A salient former dividing line between ethnic groups, namely their use of different medicinal substances, paradoxically becomes a bridge for conservative users of all groups and religions. Shops selling these substances have become centers for "nostalgia" and preserving the oriental heritage, traditional medicine, and medicinal substances! PMID:16401348

Sabale, Vidya; Sabale, P. M.; Lakhotiya, C. L.

2009-01-01

Waxes have been used in many cosmetic preparations and pharmaceuticals as formulation aids. Rice bran wax is a byproduct of rice bran oil industry. Present investigation has been aimed to explore the possible utility of rice bran wax as ointment base compared to standard base. The rice bran wax obtained, purified and its physicochemical characteristics were determined. Ointment base acts as a carrier for medicaments. The ointment base composition determines not only the extent of penetration but also controls the transfer of medicaments from the base to the body tissues. Rice bran wax base was compared with standard base for appearance, spreadability, water number, wash ability and diffusibility. The results show that rice bran wax acts as an ointment base as far as its pharmaceutical properties are concerned and it could effectively replace comparatively costlier available ointment bases.

The prevalence of diabetes mellitus (DM) has rapidly increased worldwide. Excess body fat is an important risk factor for the disease. Strategies have been indicated for the prevention and treatment of DM. Recent studies have associated the consumption of oilseeds resulting in a lower risk of developing obesity and diabetes. It is believed that this effect is associated with low glycemic index and the high fiber content, the unsaturated fatty acids and the magnesium oilseeds. However, the mechanisms involved in appetite and type 2 diabetes control have not been fully elucidated among researchers yet. Thus, the objective of the present article was to critically analyze the articles published on this subject aiming at identifying strategies which may be used in the dietary treatment of diabetes.

Percutaneous gastrostomy, is the procedure of choice to provide enteral access in patients requiring nutritional support in this way in the long run, relegating the surgical gastrostomy. We present three patients requiring percutaneous gastrostomy for nutritional support. In two cases was performed endoscopic gastrostomy and another one using interventional radiology. While performing percutaneous gastrostomy clinical incidents were not detected, but when trying the replacement of gastrostomy tubes, showed the presence of gastrocolic fistula that caused failure or turnover in one case, or abdominal pain and diarrhea in the two other cases. Despite being a safe technique, should be done a proper patient selection in order to minimize the potential complications that may occur, as gastrocolic fistula, recommending in doubtful cases test of image such CT (computerized Tomography).

Citri Fructus identification by fingerprint and chemometrics was investigated in this paper. Twenty-three Citri Fructus samples were collected which referred to two varieties as Cirtus wilsonii and C. medica recorded in Chinese Pharmacopoeia. HPLC chromatograms were obtained. The components were partly identified by reference substances, and then common pattern was established for chemometrics analysis. Similarity analysis, principal component analysis (PCA) , partial least squares-discriminant analysis (PLS-DA) and hierarchical cluster analysis heatmap were applied. The results indicated that C. wilsonii and C. medica could be ideally classified with common pattern contained twenty-five characteristic peaks. Besides, preliminary pattern recognition had verified the chemometrics analytical results. Absolute peak area (APA) was used for relevant quantitative analysis, results showed the differences between two varieties and it was valuable for further quality control as selection of characteristic components.

Pharmacological interactions of anti-inflammatory-analgesics in odontology.

2009-02-01

In this second article we describe the more interesting pharmacological interactions in dental practice based on the prescription of analgesic narcotics, paracetamol and non-selective non-steroid anti-inflammatory drugs (NSAI) (which inhibit cyclooxigenase 1 -COX 1- and cyclooxigenase 2 -COX 2-) and selective NSAIs (COX 2 inhibitors). The importance of preventing the appearance of these pharmacological interactions is because these are medicaments prescribed daily in odontology for moderate pain treatment and inflammation in the oral cavity. Paracetamol can interact with warfarin and therefore care should be taken with chronic alcoholic patients. All NSAIs reduce renal blood flow and consequently are capable of reducing the efficacy of medicaments used for treating arterial hypertension, which act via a renal mechanism. Especial attention should be taken considering the risk of interaction between the antagonists of AT1 receptors of angiostensin II (ARAII) and the NSAIs.

A potent vaccine against tuberculosis, one of the world's deadliest diseases, is needed to enhance the immunity of people worldwide, most of whom have been vaccinated with the partially effective BCG vaccine. Here we investigate novel live attenuated recombinant Listeria monocytogenes (rLm) vaccines expressing the Mycobacterium tuberculosis (Mtb) 30 kDa major secretory protein (r30/Ag85B) (rLm30) as heterologous booster vaccines in animals primed with BCG. Using three attenuated Lm vectors, rLm Δ actA (LmI), rLm Δ actA Δ inlB (LmII), and rLm Δ actA Δ inlB prfA * (LmIII), we constructed five rLm30 vaccine candidates expressing the r30 linked in-frame to the Lm Listeriolycin O signal sequence and driven by the hly promoter (h30) or linked in-frame to the ActA N-terminus and driven by the actA promoter (a30). All five rLm30 vaccines secreted r30 in broth and macrophages; while rLm expressing r30 via a constitutively active prfA * regulon (rLmIII/a30) expressed the greatest amount of r30 in broth culture, all five rLm vaccines expressed equivalent amounts of r30 in infected macrophages. In comparative studies, boosting BCG-immunized mice with rLmIII/a30 induced the strongest antigen-specific T-cell responses, including splenic and lung polyfunctional CD4+ T-cells expressing the three cytokines of interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), and interleukin-2 (IL-2) ( P < 0.001) and splenic and lung CD8+ T-cells expressing IFN-γ ( P < 0.0001). In mice and guinea pigs, rLmIII/a30 and rLmI/h30 vaccines were generally more potent booster vaccines than r30 in adjuvant and a recombinant adenovirus vaccine expressing r30. In a setting in which BCG alone was highly immunoprotective, boosting mice with rLmIII/a30, the most potent of the vaccines, significantly enhanced protection against aerosolized Mtb ( P <0.01).

Maintenance of chondrocyte phenotype and robust expression and organization of macromolecular components with suitable cartilaginous properties is an ultimate goal in cartilage tissue engineering. We used a self-aggregating suspension culture (SASC) method to produce an engineered cartilage, “cartilage tissue analog” (CTA). With an objective of understanding the stability of phenotype of the CTA over long periods, we cultured chondrocytes up to 4 years and analyzed the matrix. Both early (eCTAs) (6 months) and aged (aCTAs) (4 years) showed type II collagen throughout with higher concentrations near the edge. Using Fourier transform-infrared imaging spectroscopy (FT-IRIS), proteoglycan/collagen ratio of eCTA was 2.8 times greater than native cartilage at 1 week, but the ratio was balanced to native level (p = 0.017) by 36 weeks. Surprisingly, aCTAs maintained the hyaline characteristics, but there was evidence of calcification within the tissue with a distinct range of intensities. Mineral/matrix ratio of those aCTA with “intensive” calcification was significantly higher (p = 0.017) than the “partial,” but when compared to native bone the ratio of “intensive” aCTAs was 2.4 times lower. In this study we utilized the imaging approach of FT-IRIS and have shown that a biomaterial formed is compositionally closely related to natural cartilage for long periods in culture. We show that this culture platform can maintain a CTA for extended periods of time (4 years) and under those conditions signs of mineralization can be found. This method of cartilage tissue engineering is a promising method to generate cartilaginous biomaterial and may have potential to be utilized in both cartilage and boney repairs. PMID:21630329

Chromite alteration processes within Vourinos ophiolite

NASA Astrophysics Data System (ADS)

Grieco, Giovanni; Merlini, Anna

2012-09-01

The renewed interest in chromite ore deposits is directly related to the increase in Cr price ruled by international market trends. Chromite, an accessory mineral in peridotites, is considered to be a petrogenetic indicator because its composition reflects the degree of partial melting that the mantle experienced while producing the chromium spinel-bearing rock (Burkhard in Geochim Cosmochim Acta 57:1297-1306, 1993). However, the understanding of chromite alteration and metamorphic modification is still controversial (e.g. Evans and Frost in Geochim Cosmochim Acta 39:959-972, 1975; Burkhard in Geochim Cosmochim Acta 57:1297-1306, 1993; Oze et al. in Am J Sci 304:67-101, 2004). Metamorphic alteration leads to major changes in chromite chemistry and to the growth of secondary phases such as ferritchromite and chlorite. In this study, we investigate the Vourinos complex chromitites (from the mines of Rizo, Aetoraches, Xerolivado and Potamia) with respect to textural and chemical analyses in order to highlight the most important trend of alteration related to chromite transformation. The present study has been partially funded by the Aliakmon project in collaboration between the Public Power Corporation of Greece and Institute of Geology and Mineral Exploration of Kozani.

Maple syrup urine disease (MSUD) is a hereditary disorder of branched chain amino/keto acid metabolism, caused by a decreased activity of the branched-chain alpha- ketoacid dehydrogenase complex (BCKAD), which leads to abnormal elevated plasma concentrations of branched-chain amino acids (BCAAs) clinically manifested as a heavy burden for Central Nervous system. The toxic accumulation of substrates promotes the development of a severe and rapidly progressive neonatal encephalopathy if treatment is not immediately given. This disorder has a specific medical management in acute phase in order to minimize mortality and morbidity. For all those reasons, it is important to include the MSUD as a possible diagnosis in a encephalopathic newborn. We present a colombian newborn with classical MSUD with fatal outcome as an example of metabolic emergency and a differential diagnosis in the encephalopathic newborn.

The aim of this study is to describe the experience of a group of mothers with obese children, regarding how early bond affects the relationship that both have with food and this, in turn, impacts on childhood obesity. The present study has a qualitative, exploratory and descriptive design. The sample consists of five chilean women between 22 and 39 years old, with obese children between 2 and 4 years old. In-depth interviews were carried out and open coding strategy was used as method of analysis. Results show a tendency of mothers to establish insecure attachment relations, difficulties of tuning and expression of affection, and a predominance of a permissive parenting style around food. This has important implications for prevention and treatment of obesity, focusing on the attachment bond between mother and child. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

As the root canal system considered to be complex and unpredictable, using root canal irrigants and medicaments are essential in order to enhance the disinfection of the canal. Sodium hypochlorite is the most common irrigant in endodontics. Despite its excellent antimicrobial activity and tissue solubility, sodium hypochlorite lacks some important properties such as substantivity and smear layer removing ability. The aim of this review was to address benefits and drawbacks of combining sodium hypochlorite with other root canal irrigants and medicaments. According to the reviewed articles, NaOCl is the most common irrigation solution in endodontics. However, it has some drawbacks such as inability to remove smear layer. One of the drawbacks of NaOCl is its inability to remove the smear layer and lack of substantivity. The adjunctive use of other materials has been suggested to improve NaOCl efficacy. Nevertheless, further studies are required in this field.

The aim of this review is to discuss the role of medicaments and materials used in teeth undergoing root canal treatment and how they affect the overall prognosis of root canal treated teeth. Irrigants, medicaments and materials play a vital role in RCT. They reduce the overall microbial load within the root canal system, help reduce inter-appointment pain, and induce apexification during RCT of permanent teeth with immature apices. In addition, they also help create a hermetic coronal and periradicular seal to entomb any residual microorganisms within the canals and prevent future ingress of contaminants into the root canal system and subsequent reinfection. Whilst the role of various materials in RCT has been thoroughly investigated, the available literature and longitudinal clinical studies evaluating the affect of such materials on the prognosis of RCT is scarce, and requires further investigation. © 2017 Australian Society of Endodontology Inc.

The treatment of chronic kidney disease represents 2.5% of the National Healthcare System budget. Given the panorama of economic crisis, actions aimed at containing the costs in this kind of pathologies should be implemented. Centralization of the management of the medications used for the treatment of chronic kidney disease and its complications aims at reducing the pharmaceutical expenditure. The new contracts of public healthcare administrations with companies of dialysis centers establish a single price by which the contractor takes care of the integral management of the patients, including the dialysis therapy and pharmacological treatment. Drug management at dialysis centers will be handled by specialized pharmacists by means of the creation of pharmacy departments or drug warehouse. these measures aim at improving healthcare of the patient in hemodialysis program, with health benefits at a lower healthcare cost.

Therapeutic strategies are needed to protect dopaminergic neurons in Parkinson’s disease (PD) patients. Oxidative stress caused by dopamine may play an important role in PD pathogenesis. Selective autophagy of mitochondria (mitophagy), mainly regulated by PINK1 and PARKIN, plays an important role in the maintenance of cell homeostasis. Mutations in those genes cause accumulation of damaged mitochondria, leading to nigral degeneration and early-onset PD. AMBRA1ActA is a fusion protein specifically expressed at the mitochondria, and whose expression has been shown to induce a powerful mitophagy in mammalian cells. Most importantly, the pro-autophagy factor AMBRA1 is sufficient to restore mitophagy in fibroblasts of PD patients carrying PINK1 and PARKIN mutations. In this study, we investigated the potential neuroprotective effect of AMBRA1-induced mitophagy against 6-hydroxydopamine (6-OHDA)- and rotenone-induced cell death in human neuroblastoma SH-SY5Y cells. We demonstrated that AMBRA1ActA overexpression was sufficient to induce mitochondrial clearance in SH-SY5Y cells. We found that apoptosis induced by 6-OHDA and rotenone was reversed by AMBRA1-induced mitophagy. Finally, transfection of SH-SY5Y cells with a vector encoding AMBRA1ActA significantly reduced 6-OHDA and rotenone-induced generation of reactive oxygen species (ROS). Altogether, our results indicate that AMBRA1ActA is able to induce mitophagy in SH-SY5Y cells in order to suppress oxidative stress and apoptosis induced by both 6-OHDA and rotenone. These results strongly suggest that AMBRA1 may have promising neuroprotective properties with an important role in limiting ROS-induced dopaminergic cell death, and the utmost potential to prevent PD or other neurodegenerative diseases associated with mitochondrial oxidative stress.

Basic fibroblast growth factor (bFGF) is a cytokine that promotes the regeneration of the periodontium, the specialized tissues supporting the teeth. bFGF, does not, however, induce the synthesis of smooth muscle actin alpha 2 (ACTA2), type I collagen (COL1), or COL3, which are principal molecules in periodontal ligament (PDL) tissue, a component of the periodontium. We have suggested the feasibility of using transforming growth factor-β1 (TGFβ1) to induce fibroblastic differentiation of PDL stem/progenitor cells (PDLSCs). Here, we investigated the effect of the subsequent application of TGFβ1 after bFGF (bFGF/TGFβ1) on the differentiation of PDLSCs into fibroblastic cells. We first confirmed the expression of bFGF and TGFβ1 in rat PDL tissue and primary human PDL cells. Receptors for both bFGF and TGFβ1 were expressed in the human PDLSC lines 1-11 and 1-17. Exposure to bFGF for 2 days promoted vascular endothelial growth factor gene and protein expression in both cell lines and down-regulated the expression of ACTA2, COL1, and COL3 mRNA in both cell lines and the gene fibrillin 1 (FBN1) in cell line 1-11 alone. Furthermore, bFGF stimulated cell proliferation of these cell lines and significantly increased the number of cells in phase G2/M in the cell lines. Exposure to TGFβ1 for 2 days induced gene expression of ACTA2 and COL1 in both cell lines and FBN1 in cell line 1-11 alone. BFGF/TGFβ1 treatment significantly up-regulated ACTA2, COL1, and FBN1 expression as compared with the group treated with bFGF alone or the untreated control. This method might thus be useful for accelerating the generation and regeneration of functional periodontium.

Maintenance of chondrocyte phenotype and robust expression and organization of macromolecular components with suitable cartilaginous properties is an ultimate goal in cartilage tissue engineering. We used a self-aggregating suspension culture (SASC) method to produce an engineered cartilage, "cartilage tissue analog" (CTA). With an objective of understanding the stability of phenotype of the CTA over long periods, we cultured chondrocytes up to 4 years and analyzed the matrix. Both early (eCTAs) (6 months) and aged (aCTAs) (4 years) showed type II collagen throughout with higher concentrations near the edge. Using Fourier transform-infrared imaging spectroscopy (FT-IRIS), proteoglycan/collagen ratio of eCTA was 2.8 times greater than native cartilage at 1 week, but the ratio was balanced to native level (p = 0.017) by 36 weeks. Surprisingly, aCTAs maintained the hyaline characteristics, but there was evidence of calcification within the tissue with a distinct range of intensities. Mineral/matrix ratio of those aCTA with "intensive" calcification was significantly higher (p = 0.017) than the "partial," but when compared to native bone the ratio of "intensive" aCTAs was 2.4 times lower. In this study we utilized the imaging approach of FT-IRIS and have shown that a biomaterial formed is compositionally closely related to natural cartilage for long periods in culture. We show that this culture platform can maintain a CTA for extended periods of time (4 years) and under those conditions signs of mineralization can be found. This method of cartilage tissue engineering is a promising method to generate cartilaginous biomaterial and may have potential to be utilized in both cartilage and boney repairs.

For a number of reasons, meat products are an exceptionally adequate means for introducing different bioactive compounds into the diet without modifying eating habits. In recent years, there has been a notable development of meat products designed as potentially functional foods. Within the framework of the functional food, this article provides a general view of the reasons that motivate and justify their formulation, with special emphasis on: a) aspects to be considered in their design in order to be able to make nutrition claims and statements concerning their health-promoting properties; b) the strategies employed to optimize the presence of functional ingredients, favoring the presence of beneficial bioactive compounds and limiting others with negative consequences for our health, and c) the procedures for demonstrating a relationship between the consumption of potentially functional meat products with beneficial effects on health and the way in which these studies are reflected in the literature.

Malnutrition is very common in hospitals and inpatients with prescription of oral nutritional supplementation have improvement of the nutritional status. To detect the total acceptance rate and a possible association between oral nutritional supplements intake and nutritional status. A cross-sectional study was carried out among 398 inpatients. Fifteen types of supplements were analyzed and nutritional status was detected by Subjective Global Assessment (SGA). Rest-ingestion index (RI) was obtained and Modified Poisson's regression was used to detect associations between nutritional status and intake of nutritional supplements. The prevalence of malnutrition was 43.7% and overall acceptance of supplements was around 75%. Industrialized supplements have better acceptance among well-nourished inpatients and patients who ate less than 80% of the supplement offered (industrialized or homemade) had higher risk for malnutrition (48%). There was an association between oral nutritional supplements intake and nutritional status, despite the good acceptance rate. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA.

This study evaluated the incidence of postoperative pain after intracanal dressings with either 0.12% chlorhexidine digluconate gel (CHX) or a calcium hydroxide/camphorated paramonochlorophenol/glycerin paste (CH/CPMC). Overall, 138 asymptomatic teeth had their canals instrumented under irrigation with 2.5% NaOCl and then dressed with either CH/CPMC or CHX. The incidence of different intensity levels of postoperative pain was registered for the period between appointments. Data revealed that 84% of the total number of cases treated with either medicament showed absence of any level of pain. No case medicated with CH/CPMC and four cases (5.8%) medicated with CHX were categorized as flare-ups. There were no statistically significant differences between all possible comparisons involving the two medicaments in treatment/retreatment cases and teeth with/without apical periodontitis lesions. The low incidence of postoperative pain after the use of both medications, coupled to their antimicrobial effectiveness, gives support to using one or the other in routine treatment/retreatment.

The dosage of antineoplastic drugs has historically been based on individualized prescription and preparation according to body surface area or patient´s weight. Lack of resources and increased assistance workload in the areas where chemotherapy is made, are leading to the development of new systems to optimize the processing without reducing safety. One of the strategies that has been proposed is the elaboration by dose banding. This new approach standardizes the antineoplastic agents doses by making ranges or bands accepting a percentage of maximum variation. It aims to reduce processing time with the consequent reduction in waiting time for patients; to reduce errors in the manufacturing process and to promote the rational drug use. In conclusion, dose banding is a suitable method for optimizing the development of anticancer drugs, obtaining reductions in oncologic patients waiting time but without actually causing a favorable impact on direct or indirect costs.

Carnosine, dipeptide formed by amino acids ß-alanine and L-histidine, has important physiological functions among which its antioxidant and related memory and learning. However, in connection with the exercise, the most important functions would be associated with muscle contractility, improving calcium sensitivity in muscle fibers, and the regulatory function of pH. Thus, it is proposed that carnosine is the major intracellular buffer, but could contribute to 7-10% in buffer or buffer capacity. Since carnosine synthesis seems to be limited by the availability of ß-alanine supplementation with this compound has been gaining increasing popularity among the athlete population. Therefore, the objective of this study literature review was to examine all those research works have shown the effect of ß-alanine supplementation on athletic performance. Moreover, it also has attempted to establish a specific dosage that maximizing the potential benefits, minimize paresthesia, the main side effect presented in response to supplementation.

Introduction: As the root canal system considered to be complex and unpredictable, using root canal irrigants and medicaments are essential in order to enhance the disinfection of the canal. Sodium hypochlorite is the most common irrigant in endodontics. Despite its excellent antimicrobial activity and tissue solubility, sodium hypochlorite lacks some important properties such as substantivity and smear layer removing ability. Objective: The aim of this review was to address benefits and drawbacks of combining sodium hypochlorite with other root canal irrigants and medicaments. Discussion: According to the reviewed articles, NaOCl is the most common irrigation solution in endodontics. However, it has some drawbacks such as inability to remove smear layer. One of the drawbacks of NaOCl is its inability to remove the smear layer and lack of substantivity. Conclusion: The adjunctive use of other materials has been suggested to improve NaOCl efficacy. Nevertheless, further studies are required in this field. PMID:29387282

[Role of probiotics in obesity management].

PubMed

Prados-Bo, Andreu; Gómez-Martínez, Sonia; Nova, Esther; Marcos, Ascensión

2015-02-07

Obesity is a major public health issue as it is related to several chronic disorders, including type-2 diabetes, high blood pressure, dyslipemia, cardiovascular diseases and cancer, among others. Novel research shows that the gut microbiota is involved in obesity and metabolic disorders, revealing that obese animal and human subjects have alterations in the composition of the gut microbiota compared to their lean counterparts. Moreover, it has been observed in germ-free mice that transplantation of the microbiota of either obese or lean mice influences body weight, suggesting that the gut ecosystem is a relevant target for weight management. Certain strains of probiotics may regulate body weight by influencing the host's metabolic, neuroendocrine and immune functions. Taken together, our knowledge about the influence of gut microbiota on obesity is progressing. Therefore, modulation of its composition through probiotics may provide new opportunities to manage overweight and obesity. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

zeolites (clinoptilolites) are a family of alluminosilicates and cations clustered to form macro aggregates by small individual cavities. In the medical area they are involved in detoxification mechanisms capturing ions and molecules into their holes. Actually, we classify about 140 types of natural and 150 synthetic zeolites, for specific and selective use. Clinoptilolite is a natural zeolite and it is the most widespread compound in the medical market. this review analyzes the main fields of zeolite utilization. we searched Pubmed/Medline using the terms "zeolite" and "clinoptilolite". in zoothechnology and veterinary medicine zeolite improves the pets' fitness, removes radioactive elements, aflatoxines and poisons. Zeolite displays also antioxidant, whitening, hemostatic and anti-diarrhoic properties, projected in human care. However very scanty clinical studies have been run up to now in immunodeficiency, oncology after chemotherapy and radiotherapy as adjuvants. further clinical investigations are urgently required after this review article publication which updates the state of the art.

It is known how diet plays an important role either in cancer occurrence or its prevention. A complete revision on the literature has been performed trying to gain knowledge on the diets that can prevent for cancer occurrence, or those that can cause malignancies. Fruits and vegetables are the foods that can prevent from cancer disease, soya and fishes also have demonstrated as preventive from some types of malignancies. Clear factors causing cancer are red meat and processed meat, dairy products and alcohol. The protective roles of vitamins, antioxidants and micronutrients still have to be deeply investigated. Obesity is a clear risk factor for cancer, calorie reduction has been proposed as a factor that has protective properties in laboratory studies, but this has to be demonstrated in a clinical scenario. The diet surveillance and an adequate selection of foods can be a useful and cheap method for malignant disease prevention in the general population. Copyright AULA MEDICA EDICIONES 2014.

The food consumption assessment methods are used in nutrition and health population surveys and are the basis for the development of guidelines, nutritional recommendations and health plans, The study of these issues is one of the major tasks of the research and health policy in developed countries. Major advances nationally in this area have been made since 1940, both in the reliability of the data and in the standardization of studies, which is a necessary condition to compare changes over time. In this article the history and application of different dietary surveys, dietary history and food frequency records are analyzed. Besides information from surveys conducted at a national level, the main data currently available for public health planning in nutrition comes from nutritional analysis of household budget surveys and food balance sheets, based on data provided by the Ministry of Agriculture.

Fonseca, Jorge; Adriana, Carla; Fróis-Borges, Miguel; Meira, Tânia; Oliveira, Gabriel; Santos, José Carlos

2015-04-01

Head and neck cancer (HNC) patients tend to develop dysphagia. In order to preserve the nutritional support, many undergo endoscopic gastrostomy (PEG). In HNC patients, ostomy metastasis is considered a rare complication of PEG, but there are no reports of successful treatment of these metastatic cancers. We report the case of a 65 years old pharyngeal/laryngeal cancer patient who underwent a PEG before the neck surgery. He was considered to be cured, resumed oral intake and the PEG tube was removed. Ten months after, he returned with a metastasis at the ostomy site. A block resection of the stomach and abdominal wall was performed. Two years after the abdominal surgery, he is free of disease. Although usually considered a rare complication of the endoscopic gastrostomy, ostomy metastasis may be more frequent than usually considered and the present case report demonstrates that these patients may have a favourable outcome.

2014-12-01

Rhynchophylla is a Chinese herb commonly used in clinical practice. It's also the primary herb of some famous Chinese herbal compound such as Tianma Gouteng decoction, and Lingyang Gouteng decoction. According the record from many previous materia medica literatures, rhynchophylla should be added later during decoction. Pharmaceutical research showed that rhynchophylla alkaloids were not stable. Which has resulted in many problems in the research and its application. For example, there was not a quantitative determination method in "Chinese Pharmacopoeia" of past and present versions, which seriously impacted its quality control and product application. Firstly, records from previous materia medica literatures and "Chinese Pharmacopoeia" were systematically sorted based on the chemical stability of rhynchophylla. Secondly, pharmaceutical research including chemical compositions and their stability, pharmacological effects, extraction process and quality analysis, was reviewed after reference of literatures published at home and abroad in recent decades. Positive reference and evidence for further research and development of rhynchophylla will be provided in the article.

Ehrmann, Ernest H; Messer, Harold H; Clark, Robert M

2007-12-01

The purpose of this research is to investigate the frequency of endodontic flare-ups using a visual analogue scale. Definitions of flare-ups vary widely as does their reported frequency. A flare-up was defined as an increase of 20 or more points on the visual analogue scale for a given tooth, within the periods of 4 h and 24 h after the initial treatment appointment. The data from a previous study were used to determine the incidence of flare-ups after using three modalities (Ledermix, calcium hydroxide and no medication) to manage patients presenting for relief of pain of endodontic origin. A statistical analysis showed that there were no significant differences in flare-up rates at both the 4-h and 24-h periods between the three modalities. Further research is required using the above definition of a flare-up and standardising treatment protocols.

For thousands of years, the natural resource for Chinese materiamedica has been the foundation of the traditional Chinese medicine industry, which provides abundant medicine for human. In recent years, increasing demands and irrational exploitation led to a lot of problems such as rapid decrease of traditional Chinese herbs reserves, low quality of medicine and dismishing traditional cultures. These restricted the development of the traditional Chinese medicine. To solve these problems, scientists have done much work on investigating traditional Chinese medicine resources, exploring the metabolic pathway of bioactive ingredients, cultivating new varieties, and carrying out synthetic biology. These studies provided a theoretical basis for sustainable utilizationand future developmentof traditional Chinese medicine resources.

Figures of Colombian immigrants in Venezuela in the period 1981-1986 as well as the development of their socio-demographic profile and their integration into the labor market are analyzed by means of ad hoc tables drawn from a Sample Home Survey by the Oficina Central de Estadisticas e Informatica and information from the civil record office. It is estimated that in 1987 there are only half a million Colombians in Venezuela and, contrary to what is generally assumed, not only has the afflux decreased (3/4 of the Colombians entered before 1981), but also a return migration can be observed. Colombian immigration is not homogeneous, but is made up of different groups as far as their professional skills and occupations are concerned. The number of Colombians engaged in household service and those living in rural areas has decreased, but not the number of active farm workers. A greater proportion of Colombians engaged in trade and sales activities is observed, but artisans and skilled labor are still the majority.

To comparing attitudes towards end-of-life (EOL) decisions in newborn infants between seven European countries. One paediatrician and one lawyer from seven European countries were invited to attend a conference to discuss the practice of EOL decisions in newborn infants and the legal aspects involved. All paediatricians/neonatologists indicated that the best interest of the child should be the leading principle in all decisions. However, especially when discussing cases, important differences in attitude became apparent, although there are no significant differences between the involved countries with regard to national legal frameworks. Important differences in attitude towards neonatal EOL decisions between European countries exist, but they cannot be explained solely by medical or legal reasons. ©2012 The Author(s)/Acta Paediatrica ©2012 Foundation Acta Paediatrica.

Second quantization of a covariant relativistic spacetime string in Steuckelberg-Horwitz-Piron theory

A relativistic 4D string is described in the framework of the covariant quantum theory first introduced by Stueckelberg [ Helv. Phys. Acta 14, 588 (1941)], and further developed by Horwitz and Piron [ Helv. Phys. Acta 46, 316 (1973)], and discussed at length in the book of Horwitz [Relativistic Quantum Mechanics, Springer (2015)]. We describe the space-time string using the solutions of relativistic harmonic oscillator [ J. Math. Phys. 30, 66 (1989)]. We first study the problem of the discrete string, both classically and quantum mechanically, and then turn to a study of the continuum limit, which contains a basically new formalism for the quantization of an extended system. The mass and energy spectrum are derived. Some comparison is made with known string models.

To determine in vitro the time required for recontamination of coronally sealed canals medicated with either calcium hydroxide (CaOH2), 2% chlorhexidine gel (CG) or with a combination of both. Eighty intact, caries-free, premolar teeth with straight roots and mature apices were selected for the study. After biomechanical preparation of 75 teeth, they were randomly divided into nine groups according to the intracanal medicament and the coronal seal with 'Intermediate Restorative Material' (IRM) as follows: (i) 10 teeth medicated with CG, coronally unsealed; (ii) 10 teeth medicated with CaOH2, coronally unsealed; (iii) 10 teeth medicated with CaOH2 + CG, coronally unsealed; (iv) 10 teeth medicated with CG + coronal seal; (v) 10 teeth medicated with CaOH2 + coronal seal; (vi) 10 teeth medicated with CG + CaOH2 + coronal seal; (vii) 10 teeth without intracanal medicament and coronally sealed; (viii) 5 teeth without intracanal medicament and coronally unsealed, used as the positive control group (PC); (ix) 5 teeth with intact crowns used as the negative control group (NC). Glass flasks were filled with Brain Heart Infusion broth (BHI), so that only the root apex was in contact with the broth, while the crown was immersed in human saliva + BHI (3:1). The flasks were then incubated at 37 degrees C in an atmosphere of 10% CO2, and microbial growth was checked daily. All specimens of the PC showed contamination within 1 day of incubation, while the NC showed no evidence of broth turbidity. Recontamination was detected after an average time of 3.7 days in the unsealed canals medicated with CG, 1.8 days in the group medicated with CaOH2 and 2.6 days in the group medicated with CaOH2 + CG. When the crowns were sealed with IRM, recontamination was detected within 13.5 days in the canals medicated with CG, after 17.2 days in the group medicated with CaOH2 and after 11.9 days in the group medicated with CG + CaOH2. The group with no medication, but sealed with IRM, showed

Baicalin supplementation reduces serum biomarkers of skeletal muscle wasting and may protect against lean body mass reduction in cancer patients: Results from a pilot open-label study.

2016-07-01

Muscle wasting in patients with cancer has been linked to an increased activity of nuclear factor κB (NF-κB) and higher circulating levels of activin-A (ActA), a negative growth factor for muscle mass. Baicalin is a natural flavonoid that can reduce skeletal muscle atrophy in animal models of cancer cachexia by inhibiting NF-κB. This pilot open-label study assessed the effects of baicalin supplementation (50 mg daily for 3 months) in cancer patients who showed involuntary weight loss >5% over the past 6 months. A total of 20 patients were investigated. Participants were evaluated at baseline and at the end of the 3-month study period for the following endpoints: 1) changes from baseline in serum NF-κB and ActA levels; and 2) change from baseline in lean body mass (LBM). We observed significant reduction in both NF-κB (p<0.05) and ActA (p<0.05) serum levels from baseline to 3 months. At 3 months, patients also showed a significant mean increase in LBM (+0.8 kg, p<0.05 compared with baseline). Our pilot open-label data suggest that baicalin supplementation is potentially useful for contrasting lean body mass reduction in cancer patients with involuntary weight loss, an effect which is likely mediated by the inhibition of negative growth factors for muscle mass.

The spectral sensitivity of the human short-wavelength sensitive cones derived from thresholds and color matches.

PubMed

Stockman, A; Sharpe, L T; Fach, C

1999-08-01

We used two methods to estimate short-wave (S) cone spectral sensitivity. Firstly, we measured S-cone thresholds centrally and peripherally in five trichromats, and in three blue-cone monochromats, who lack functioning middle-wave (M) and long-wave (L) cones. Secondly, we analyzed standard color-matching data. Both methods yielded equivalent results, on the basis of which we propose new S-cone spectral sensitivity functions. At short and middle-wavelengths, our measurements are consistent with the color matching data of Stiles and Burch (1955, Optica Acta, 2, 168-181; 1959, Optica Acta, 6, 1-26), and other psychophysically measured functions, such as pi 3 (Stiles, 1953, Coloquio sobre problemas opticos de la vision, 1, 65-103). At longer wavelengths, S-cone sensitivity has previously been over-estimated.

Pinworm (Enterobius vermicularis) is the most common parasite among mankind. Ectopic pinworm infections in number of organs are broadly reported. The aim of this report is to review the pinworm infection in the scrotum on the basis of our case. Our patient is a young boy with persistent pain in the scrotums together with abdominal symptoms. He underwent several urgent operations. Pinworm was finally found in appendix vermiformis. We hypothesize that concurrent unresponsive orchido-epididymitis was caused by pinworm as well. Eradication happened finally with pyvrinembonate. Pinworm is a parasite that lives usually in the bowel. Many ectopic locations, like scrotum, are known. Orchido-epididymitis by pinworm has to be kept in mind when treating boys with persistent scrotal pain. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

Furosemide, because of its actions on the ubiquitous Na(+) -K(+) -2Cl(-) isoform cotransporter and its promotion of prostanoid production and release, also has non-diuretic effects on vascular smooth muscle, airways, the ductus arteriosus and theoretically the gastrointestinal tract. Loop diuretics also affect the central nervous system through modulation of the GABA-A chloride channel.   The loop diuretics have a variety of biological effects that are potentially harmful as well as beneficial. Care should be taken with the use of these agents because the range of their effects may be broader than the single action sought by the prescribing physician. © 2012 The Author(s)/Acta Paediatrica © 2012 Foundation Acta Paediatrica.

The abundance of C in carbonaceous and ordinary chondrites decreases exponentially with increasing shock pressure as inferred from the petrologic shock classification of Scott et al. [Scott, E.R.D., Keil, K., Stoffler, D., 1992. Shock metamorphism of carbonaceous chondrites. Geochim. Cosmochim. Acta 56, 4281-4293] and Stoffler et al. [Stoffler, D., Keil, K., Scott, E.R.D., 1991. Shock metamorphism of ordinary chondrites. Geochim. Cosmochim. Acta 55, 3845-3867]. This confirms the experimental results of Tyburczy et al. [Tyburczy, J.A., Frisch, B., Ahrens, T.J., 1986. Shock-induced volatile loss from a carbonaceous chondrite: implications for planetary accretion. Earth Planet. Sci. Lett. 80, 201-207] on shock-induced devolatization of the Murchison meteorite showing that carbonaceous chondrites appear to be completely devolatilized at impact velocities greater than 2 km s-1. Both of these results suggest that C incorporation would have been most efficient in the early stages of accretion, and that the primordial C content of the Earth was between 10(24) and 10(25) g C (1-10% efficiency of incorporation). This estimate agrees well with the value of 3-7 x 10(24) g C based on the atmospheric abundance of 36Ar and the chondritic C/36Ar (Marty and Jambon, 1987). Several observations suggest that C likely was incorporated into the Earth's core during accretion. (1) Graphite and carbides are commonly present in iron meteorites, and those iron meteorites with Widmanstatten patterns reflecting the slowest cooling rates (mostly Group I and IIIb) contain the highest C abundances. The C abundance-cooling rate correlation is consistent with dissolution of C into Fe-Ni liquids that segregated to form the cores of the iron meteorite parent bodies. (2) The carbon isotopic composition of graphite in iron meteorites exhibits a uniform value of -5% [Deines, P., Wickman, F.E. 1973.

Apical periodontitis (AP) is one of the most prevalent diseases of the teeth. Treatment of AP is based on the removal of the cause, i.e., bacteria from the root canals. Achievement of adequate bacterial eradication in one appointment treatment remains a controversy. This prospective study was conducted with the objective to compare the periapical healing of teeth with AP treated in (a) single visit versus (b) two visits, either with or without Vitapex as an intracanal medicament. Patients were selected randomly from the Department of Conservative Dentistry and Endodontics. Forty-three patients (81 teeth) met the inclusion criteria, i.e., AP (both symptomatic and asymptomatic) visible radiographically size ≥2 mm × 2 mm, not suffering from any immune-compromising disease, age between 16 and 65 years and tooth not accessed previously. Patients were randomly divided into three groups, i.e., single-visit group (Group 1), multi-visit group without any intracanal medicament (Group 2), and multi-visit group with Vitapex as interim intracanal medicament (Group 3). Comparison was done radiographically using periapical index (PAI). The primary outcome measure was the change in periapical radiolucency after 1 year assessed by PAI scores. The Mann-Whitney U-test was used to evaluate differences between groups at baseline (immediate postoperative) and at the 12-month follow-up evaluation. Change in PAI score for each group from baseline to 12-month follow-up evaluation was tested with the Wilcoxon signed rank test. The secondary outcome measures, proportion of teeth in each group that could be considered improved (decreased PAI score) or healed (PAI <2), were assessed with the Chi-square test. No statistically significant difference in periapical healing was found between three groups. After 1-year evaluation, no difference in periapical healing was found between single-visit treatment and multi-visit treatment groups with the given sample size.

Oral hygiene products, medications and drugs - hidden aetiological factors for dental erosion.

PubMed

Hellwig, Elmar; Lussi, Adrian

2014-01-01

Acidic or EDTA-containing oral hygiene products and acidic medicines have the potential to soften dental hard tissues. The low pH of oral care products increases the chemical stability of some fluoride compounds and favours the incorporation of fluoride ions in the lattice of hydroxyapatite and the precipitation of calcium fluoride on the tooth surface. This layer has some protective effect against an erosive attack. However, when the pH is too low or when no fluoride is present these protecting effects are replaced by direct softening of the tooth surface. Oral dryness can occur as a consequence of medication such as tranquilizers, antihistamines, antiemetics and antiparkinsonian medicaments or of salivary gland dysfunction. Above all, patients should be aware of the potential demineralization effects of oral hygiene products with low pH. Acetyl salicylic acid taken regularly in the form of multiple chewable tablets or in the form of headache powder, as well as chewing hydrochloric acids tablets for the treatment of stomach disorders, can cause erosion. There is most probably no direct association between asthmatic drugs and erosion on the population level. Consumers and health professionals should be aware of the potential of tooth damage not only by oral hygiene products and salivary substitutes but also by chewable and effervescent tablets. Several paediatric medications show a direct erosive potential in vitro. Clinical proof of the occurrence of erosion after use of these medicaments is still lacking. However, regular and prolonged use of these medicaments might bear the risk of causing erosion. Additionally, it can be assumed that patients suffering from xerostomia should be aware of the potential effects of oral hygiene products with low pH and high titratable acidity. © 2014 S.

To determine the time required for the recontamination of root canals medicated with four different materials. A total of 60 intact, caries-free, human single-rooted teeth with straight roots were selected for this study. After chemo-mechanical preparation they must be changed in the specimens into seven groups: 10 teeth medicated with calcium hydroxide (Ca(OH) 2) + Camphorated paramonochlorophanol (CPMC) (G.1); 10 medicated with 2.5% Sodium hypochlorite (NaOCL) (G.2); 10 medicated with 2% Chlorhexidine gluconate (CHX) in gel (G.3); 10 medicated with 2% CHX in gel + Ca(OH) 2 (G.4); 10 without intracanal medicament and sealed with a coronal temporary filling (G.5). Five teeth were without intracanal medicament and coronally unsealed, used as the positive control group (PC) (G.6) and 5 teeth with intact crowns used as the negative control group (NC) (G.7). Glass vials with rubber stoppers were adjusted for use. The medicaments were prepared and injected into the root canals using sterile plastic syringes. An apparatus was used to evaluate for 30 days leakage. The chamber was filled with 3 ml of human saliva and Brain Heart Infusion (BHI) broth, incubated at 37 degrees C and checked daily for the appearance of turbidity in the BHI broth. Recontamination was detected after an average time of 2.6 days in group 2, 15.9 days in group 3, 30 days in group 1, 27.6 days in group 4, 2.9 days in group 5, 1 day in the positive control, and there was no contamination in the negative control group. The NaOCl group showed the highest worst average of recontamination; on the other hand, high averages were also shown by Ca(OH) 2 + CPMC and Ca(OH) 2 + 2% CHX in gel.

On the local applications of antibiotics and antibiotic-based agents in endodontics and dental traumatology.

Antibiotics are a valuable adjunctive to the armamentarium available to health professionals for the management of bacterial infections. During endodontic treatment and when managing trauma to the teeth, antibiotics may be applied systemically (orally and/or parenterally) or locally (i.e. intra-dentally via irrigants and medicaments). Due to the potential risk of adverse effects following systemic application, and the ineffectiveness of systemic antibiotics in necrotic pulpless teeth and the periradicular tissues, the local application of antibiotics may be a more effective mode for delivery in endodontics. The aim of this article was to review the history, rationale and applications of antibiotic-containing irrigants and medicaments in endodontics and dental traumatology. The search was performed from 1981 to 2008 and was limited to English-language papers. The keywords searched on Medline were 'Antibiotics AND endodontics', 'Antibiotics AND root canal irrigation', 'Antibiotics AND intra-canal medicament', 'Antibiotics AND Dental trauma' and 'Antibiotics AND root resorption'. The reference section of each article was manually searched to find other suitable sources of information. It seems that local routes of antibiotic administration are a more effective mode than systemic applications. Various antibiotics have been tested in numerous studies and each has some advantages. Tetracyclines are a group of bacteriostatic antibiotics with antibacterial substantivity for up to 12 weeks. They are typically used in conjunction with corticosteroids and these combinations have anti-inflammatory, anti-bacterial and anti-resorptive properties, all of which help to reduce the periapical inflammatory reaction including clastic-cell mediated resorption. Tetracyclines have also been used as part of irrigating solutions but the substantivity is only for 4 weeks. Clindamycin and a combination of three antibiotics (metronidazole, ciprofloxacin and minocycline) have also been

Union of chemists exploited the disputes between pharmacists and legislators for its own prosperity. In 1780 the sale of natural drugs was permitted to the chemists for first time and the Trade Rules of 1856 (later amended) gave them a possibility of production, preparation and sale of poisons and medicaments, unless they were reserved for pharmacists only (section 15, article 14). Among the first founders of chemist's shops belonged the pharmacists who could not establish their own pharmaceutical store due to lack of finance or complaints from their colleagues. The chemist's didn't have to fulfill the obligatory requirements for rooms and equipment, they were not regularly checked and they had less expenses and also lower prices. Their lower profit from the sale of medicaments was compensated by selling typical chemist's articles. The pharmacists brought the level of chemists nearly to the level of organized pharmacy (pharmaceutics supervisory committee, division into regions, a two-years special school, producing and purchasing cooperatives). However, around 1925 the pharmacists became aliens from the point of view of chemists. The chemists felt their own existence threatened and tried to refuse pharmaceutical studies as an approval for chemist trade and tried to limit the sale of cosmetics and dietetics in the pharmaceutical stores. Without bashfulness, they themselves dispatched and prepared medicaments on medical and veterinary prescriptions even though it was illegal. Later they tried to legalize this state during the discussions of the reform of pharmaceutical law. Protesting pharmacists did not have efficient support either from the pharmaceutics supervisory committee, Ministry of Health Care, or Chamber of Commerce. The state solution to this problem which lacked any concept, and together with inconsistency and disunity among pharmacists themselves contributed to deepen the problems between pharmacists and chemists. Unfortunately, pharmacists often focused

To demonstrate that a nutritional support intervention, via naso-enteral tube-feeding or gastrostomy, has a significant impact on the nutritional status and body composition in severely malnourished children with cerebral palsy spastic quadriplegia. Thirteen patients with moderate/severe malnutrition and cerebral palsy spastic quadriplegia who were fed via naso-enteral tube-feeding or gastrostomy were included in a cohort study. Anthropometric measurements and estimated body composition by bioelectric impedance analysis were obtained. ANOVA and Wilcoxon tests were used. During the four weeks of nutritional recovery, an average weight increase of 2700 g was achieved. There were significant increases in anthropometric indicators, including BMI and weight/length (p < 0.01). The increase in arm fat area was significantly higher than the increase in arm muscle area (104.5 vs 17.5%). Intensive nutritional support for four weeks had a significant effect on the nutritional status and body composition of severe and moderately malnourished children with cerebral palsy spastic quadriplegia.

Diet, along with lifestyle factors, is an important determinant of the health status of an individual and of a community. Dietary assessment at the population level provides us with key information on the frequency and distribution of possible inadequate diets and/or nutritional status. It is also useful as input into the elaboration of food and nutrition policies aiming to improve dietary habits and the health status of a community. This article reviews the characteristics, advantages and limitations of the 24-hour dietary recall method (24hDR), which is one of the most widely used tools in nutrition epidemiology to identify food, energy and nutrient intake in national nutrition surveys, cross-sectional studies, clinical trials and cohort studies as well as in the evaluation of individual dietary intake and Total Diet assessment. To reduce the key factors associated with bias, the importance of previously trained interviewers is highlighted, as well as the role of support materials and the contribution of novel technologies.

the aim of this study was to evaluate the influence of consumption of a ketogenic diet supplemented with triheptanoin, a medium-chain anaplerotic triacylglycerol, on the liver fatty acid profile of Wistar rats. three groups of male Wistar rats (n = 10) were submitted to an AIN-93 control diet, a triheptanoin- based ketogenic diet, or a soybean oil-based ketogenic diet for 60 days. Excised livers were subjected to lipid extraction and methylation to obtain fatty acids methyl esters, which were subjected to gas chromatography- mass spectrometry. compared to the rats fed the control diet, those fed ketogenic diets showed a significant reduction in the concentrations of 9-hexadecenoic and 9-octadecenoic acids, whereas those fed triheptanoin showed increased levels of octadecanoic acid. changes in the liver fatty acid profiles of the rats fed a triheptanoin-based or a soybean oil-based ketogenic diet did not seem to be related to the dietary fat source, but rather to the characteristics of the ketogenic diets themselves.

Before, during and after physical activity, hydration is a limiting factor in athletic performance. Therefore, adequate hydration provides benefits for health and performance of athletes. Besides, hydration is associated to the intake of carbohydrates, protein, sodium, caffeine and other substances by different dietary aids, during the training and/or competition by athletes. These requirements have led to the development of different products by the food industry, to cover the nutritional needs of athletes. Currently in the European context, the legal framework for the development of products, substances and health claims concerning to sport products is incomplete and scarce. Under these conditions, there are many products with different ingredients out of European Food Safety Authority (EFSA) control where claims are wrong due to no robust scientific evidence and it can be dangerous for the health. Further scientific evidence should be constructed by new clinical trials in order to assist to the Experts Commitees at EFSA for obtaining robust scientific opinions concerning to the functional foods and the individual ingredients for sport population.

Obesity is a chronic disease with multiple origins. It is a widespread global phenomenon carrying potentially serious complications which requires a multidisciplinary approach due to the significant clinical repercussions and elevated health costs associated with the disease. The most recent evidence indicates that it shares a common characteristic with other prevalent, difficult-to-treat pathologies: chronic, low-grade inflammation which perpetuates the disease and is associated with multiple complications. The current interest in lipoinflammation or chronic inflammation associated with obesity derives from an understanding of the alterations and remodelling that occurs in the adipose tissue, with the participation of multiple factors and elements throughout the process. Recent research highlights the importance of some of these molecules, called pro-resolving mediators, as possible therapeutic targets in the treatment of obesity. This article reviews the evidence published on the mechanisms that regulate the adipose tissue remodelling process and lipoinflammation both in obesity and in the mediators that are directly involved in the appearance and resolution of the inflammatory process.

Non-scientific classification of Chinese herbal medicine as dietary supplement.

Bao, Kexin

2017-03-01

This article focuses the category status of Chinese herbal medicine in the United States where it has been mistakenly classifified as a dietary supplement. According to Yellow Emperor Canon of Internal Medicine (Huang Di Nei Jing), clinical treatment in broad sense is to apply certain poisonous medicines to fight against pathogeneses, by which all medicines have certain toxicity and side effect. From ancient times to modern society, all, or at least most, practitioners have used herbal medicine to treat patients' medical conditions. The educational curriculums in Chinese medicine (CM) comprise the courses of herbal medicine (herbology) and herbal formulae. The objective of these courses is to teach students to use herbal medicine or formulae to treat disease as materia medica. In contrast, dietary supplements are preparations intended to provide nutrients that are missing or are not consumed in suffificient quantity in a person's diet. In contrast, Chinese herbs can be toxic, which have been proven through laboratory research. Both clinical practice and research have demonstrated that Chinese herbal medicine is a special type of natural materia medica, not a dietary supplement.

To evaluate the beliefs, attitudes and phobias that Mexican medical and psychology students have towards obese people. A cross-sectional study was conducted with 528 students enrolled at the Autonomous University of Baja California in psychology and medical schools. Weight, height and waist circumference were evaluated. Beliefs about obesity were assessed with the BAOP scale, attitudes towards obese people by the ATOP scale and obesity phobias by the F-scale. Participants achieved a mean F-scale score of 3.4. Only seven per cent showed neutral or positive attitudes towards obesity (≤2.5). Less fat phobia was associated with beliefs that obesity was not a result of the person's self-control (p = 0.0001) and had better attitudes towards obese people (p = 0.0001). Men had higher risk of fat phobia (OR = 1.5). High prevalence of phobias and negative attitudes towards obesity was observed. Men had higher stigma. Copyright AULA MEDICA EDICIONES 2014.

Analyze the level of Life Quality (LQ) in relation to nutritional status in a sample of primary school children. Cross sectional study with 298 participants (53.35% female) of 8-12 years. LQ was assessed by the KIDSCREEN-10 questionnaire . Measures of weight and size were taken. The BMI (normal-weight, overweight and obesity) was categorized using standard criteria. To establish the relationship between the different statistical variables was performed the Kolmogorov- Smirnov test and analysis of variance. Nutritional status was significantly correlated with LQ (F = 5.096; p =, 007). School children with a normal- weight state showed higher LQ levels compared to those overweight (p = .015) and obese (p =, 013). The results show that nutritional status acts as a differentiating factor in LQ. Adopting active lifestyle behaviours that promote a healthy nutritional status not only can have benefits over health biological parameters (such as physical condition) but can also contribute to improve other LQ indicators and mental health .

Genetic variation of apolipoproteins, diet and other environmental interactions; an updated review.

2013-01-01

This paper summarizes the recent findings from studies investigating the potential environmental modulation of the genetic variation of apolipoprotein genes on metabolic traits. We reviewed nutrigenetic studies evaluating variations on apolipoproteins-related genes and its associated response to nutrients (mostly dietary fatty acids) or any other dietary or environmental component. Most revised research studied single nucleotide polymorphism (SNP) and specific nutrients through small intervention studies, and only few interactions have been replicated in large and independent populations (as in the case of -265T > C SNP in APOA2 gene). Although current knowledge shows that variations on apolipoprotein genes may contribute to the different response on metabolic traits due to dietary interventions, evidence is still scarce and results are inconsistent. Success in this area will require going beyond the limitations of current experimental designs and explore the hypotheses within large populations. Some of these limitations are being covered by the rapidly advance in high-throughput technologies and large scale-genome wide association studies. Copyright © AULA MEDICA EDICIONES 2013.

Therefore, the aim of this study was to compare patterns of habits in pre-university and university students in west-central area of Madrid. Descriptive longitudinal study with randomly selected students from Madrid in Madrid universities and schools-institutes. Accepting to participate 1590 students of both sex: 653 males (4,1%) and 937 women (58,9%). To facilitate the study were classified into ≤ 17 years (pre university) and ≥ 18 years (university). BMI, physical activity, alcohol consumption and negative habits with regard to food consumption was studied. Almost 80% have normal weight, are more active pre-university. Gender differences were observed, which should guide the actions of intervention in terms of physical activity or habits. It seems essential to make nutritional programs as well as psychosocial intervention in adolescents and youth to prevent and / or reduce alcohol consumption. Copyright AULA MEDICA EDICIONES 2014.

The continued appearance of scientific evidence about the role of diet and/or its components in health and wellness, has favored the emergence of functional foods which currently constitute one of the chief factors driving the development of new products. The application of multiple emulsions opens new possibilities in the design and development of functional foods. Multiple emulsions can be used as an intermediate product (food ingredient) into technological strategies normally used in the optimization of the presence of bioactive compounds in healthy and functional foods. This paper presents a summary of the types, characteristics and formation of multiple emulsions, possible location of bioactive compounds and their potential application in the design and preparation of healthy and functional foods. Such applications are manifested particularly relevant in relation to quantitative and qualitative aspects of lipid material (reduced fat/calories and optimization of fatty acid profile), encapsulation of bioactive compounds mainly hydrophilic and sodium reduction. This strategy offers interesting possibilities regarding masking flavours and improving sensory characteristics of foods. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA.

Since a new advanced therapy medicinal product is discovered until finally allowed its sale in the domestic market, it has to overcome a series of stages. Biomedical research is the first phase, currently its situation is encouraging to the increase in the number of clinical trials in Spain and in the rest of the world, despite the economic situation and the various difficulties that have faced the pharmaceutical laboratories. The next phase consists in obtaining the authorization of marketing of the European Medicines Agency. After authorization, will attempt to set a fair and moderate price for inclusion in the list of health provision of Social Security. A price for a drug that provides added value to health and society, a price that is generated profits for the pharmaceutical companies that hope to make up for the years of work and investment. Commitment to advanced therapy must be clear and forceful, to fund ongoing research projects and encouraging their creation with economic aid. Copyright AULA MEDICA EDICIONES 2014.

To evaluate the per capita availability of energy and macronutrients in the home and frequency of food consumption by adolescents and to relate them with anthropometric and biochemical variables, as well as verify if the eating habits of parents are associated to the children. We evaluated the weight, height, body fat (%BF), glucose, insulin, triglycerides, total cholesterol (TC) and fractions of 120 adolescents. We evaluated also the eating habits of adolescents and their parents. Adolescents with more than 35% of available lipids had 9.1-fold higher chances of presenting alterations in TC. Those who replaced the main meals for snacks had 3.66, 4.66 and 2.82 higher chances of presenting alterationsin %BF, insulin and triglycerides, respectively. The daily consumption of fruit was considered as a protective factor in relation to hyperinsulinemia. There was a similar feeding behavior among adolescents and their mothers. The results suggest the importance of specific attention to adolescent health, focused on family education. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA. All rights reserved.

To estimate the frequency, distribution, and trends of food security/insecurity conditions of families in Chiapas and their relationship with low income factor and sociodemographic characteristics. Retrospective and cross-sectional descriptive study. Information of 1430 households from The National Health and Nutrition Survey 2012 was included. The Food Insecurity was measured using the harmonized version of the Latin and Caribbean Food Security Scale for México. 83% of households in Chiapas has some type of food insecurity, 86.5% is concentrated in the lower socioeconomic levels, 85% of households in rural areas have food insecurity, 87% of households beneficiary of Oportunidades still have food insecurity. A large part of this population continues to have high levels of Food Insecurity. Clearly targeted social programs designed to eliminate this lag, fail to reduce levels of access to food which affects the physical and intellectual potential development of Chiapas people, becoming an obstacle to the development of the State. Reorientation of food policy in México is considered. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

[Soya isoflavones and evidences on cardiovascular protection].

PubMed

González Cañete, Natalia; Durán Agüero, Samuel

2014-06-01

Soya isoflavones represent a group of non-nutritive, bioactive compounds, of non-steroidal phenolic nature that are present in soy bean and derived foods. They share with other compounds the capacity of binding to estrogenic receptors from different cells and tissues so that they may act as phytoestrogens. The current interest in these compounds comes from the knowledge that in Asian populations with high levels of their consumption the prevalence of cancer and cardiovascular disease is lower, as compared to the Western countries populations. This cardiovascular benefit would be the result not only of the modulation of plasma lipids, which is a widely studied mechanism. This paper reviews the published evidence about the beneficial effects of soya isoflavones and the different mechanisms of action that would benefit cardiovascular health and that surpass the mechanisms traditionally approached such as the modulation of plasma lipids, and that implicate the regulation of cellular and enzymatic functions in situations such as inflammation, thrombosis, and atherosclerotic progression.

Gutiérrez López, Cristina; Mauriz, Jose L; Culebras, Jesús M

2015-07-01

Nowadays, balanced scorecards have updated traditional management systems in the business sector. In this way, Kaplan and Norton propose performance measurement through several perspectives with a logical sequence: internal processes and learning impact client services, so that financial performance is affected. The aim of the present paper is to analyze the main characteristics of balanced scorecard when it is applied to non-for-profit companies and, specifically to the health sector in the clinical nutrition field. This model improves the economic vision of management with clinical indicators that represent healthcare professional's perspective. The balanced scorecard would allow a proper monitoring and tracking system for the main healthcare indicators. This contributes to a better control in comparison with standards that are associated with adequate quality assistance. Owing to the role of management accounting and cost calculations, the definition of healthcare professionals as clients or users, and clinical results relevance, it is necessary to adapt the balanced scorecard to the specific characteristics of the clinical field, redefining both perspectives and indicators.

In the last decade, it has been suggested that whole- body vibration training (WBV) may increase neuromuscular performance and consequently affect the muscular improvement as either acute response to vibration or chronic adaptation training. Vibrating platforms generate frequencies from 5-45 Hz and vertical oscillations of 1-11 mm peak to peak, affecting more or less intensity acceleration changing by combining frequency and amplitude. Vibration training, in a session as various offers different results in regard to changes in body composition and in increasing the vertical jump, sprint, and the different manifestations of force development. These promising results await further research to establish parameters (duration, frequency and amplitude) with vibration stimulation in young active subjects. This literature review provides an update on the scientific evidence on the body vibrations in order to answer the question whether WBV, meaning the exercise by increasing the gravitational load collection, is a treatment option if the aim is to improve neuromuscular function, flexibility, balance, agility, coordination and body composition.

Over the last few years, changes in cutaneous homoeostasis resulting from sports activities have been reported. In particular, alterations in sweating mechanisms, the hydrolipid barrier, and surface bacterial flora, together with exposure to atmospheric conditions and the need to use medicaments, detergents, and other topical substances, predispose subjects to allergic contact dermatitis. To evaluate the incidence of allergic contact dermatitis in a group of young people practising sports activities. Patch tests were performed to confirm the diagnosis of irritant or allergic dermatitis; in addition, the radioallergoabsorbent test (RAST) to latex was evaluated in the group studied. Allergic contact dermatitis caused by thiourams (23.3%) and mercaptobenzothiazole (20.9%) was prevalent. Other haptens, such as benzocaine and nickel, which are contained in clothing, equipment, topical medicaments, and creams used for massage, were also allergenic. In two cases, RAST positivity to latex was registered. -The results suggest that close contact with sports equipment may increase the incidence of allergic contact dermatitis. Students practising certain sports may have "professional" allergic contact dermatitis to additives used in the production of rubber.

INTRODUCTIÓN: Obesity is a serious public health problem in Mexico, the National Health and Nutrition Survey (ENSANUT 2012) reported a 34.4% prevalence of overweight, and obesity in children aged 5-11. Recent research has suggested that the gut microbiota may be a risk factor of obesity through its influence on human metabolism. To evaluate association between the intestinal microbiota profile and obesity among children and whether this association is modified depending on the feeding pattern of a sample of schoolchildren from Mexico City. METODOLOGY AND RESULTS: Cross-sectional study on 1042 children aged 6-14 years; physical activity questionnaire, personal medical history and heredofamilial of obesity and type 2 diabetes were administered to all the children. Eating patterns was performed by principal component analysis (PCA). The association between intestinal microbiota and overweight / obesity depending on diet was assessed with logistic regression models. Our results shows that the interaction between the intestinal microbiota and diet, particularly high in fats and simple carbohydrates increases the chance of developing obesity.

Top athletes are subjected to intense training to achieve high performance. There are factors such as diet and strenuous exercise that affects body composition and can modify the performance. The aim of the study was to evaluate the effect of a personalized plan of diet and training on body composition. We studied the body composition of 18 professional rugby players using Kinanthropometry parameters. The study was conducted from the preseason to the end of the season taking into account the position of the player for measuring exercise intensity, and developing a personalized nutritional and training plan to each player. At baseline the players were away from the internationally recommended body composition, with high percentages of body fat. Appropriate and personalized diet plans and training custom achieved fat percentages close to those recommended. The personalized program of diet and training directed has adequate leverage to improve all parameters studied them bringing them as close to the ideal. Copyright AULA MEDICA EDICIONES 2014.

In recent years, antioxidant supplements have become popular to counter the effects of free radicals and muscle damage symptoms, including delayed onset muscle soreness (DOMS). To conduct a systematic review in different databases to determine the effects of antioxidant supplements on DOMS. We conducted a search in databases; Cochrane, Pubmed, Scopus and SportDiscus and Web of Science (WOS). The words and acronyms used were; Delayed onset muscle soreness, exercise induced muscle damage, DOMS, EIMD, antioxidant and oxidative stress. 54 articles were identified of which 48 were retreived, all in English, 17 related to vitamin C and E, supplements polyphenolic correspond to fourteen, eleven other antioxidant supplements and six to commercial supplements, all of them used to diminish the DOMS and other variables. Both vitamins and commercial supplements have low effectiveness in reducing DOMS, while polyphenols and other antioxidant supplements show moderate to good effectiveness in combating DOMS. However, most of the studies have effectiveness in reducing other symptoms of muscle damage besides helping in the post-exercise recovery. Copyright AULA MEDICA EDICIONES 2014.

Multimodal protocols to optimize perioperative care and to accelerate postoperative recovery include abbreviated pre-and postoperative fasting. The aim of this study was to investigate the pre and postoperative fasting period and the factors that influence it in patients who underwent elective operations. We included patients who underwent surgery of the digestive tract and abdominal wall. Data were collected from the patients and from their personal health records. We included 135 patients between 19 and 89 years old. Most were adults (75.55%), female (60.74%) and the most common procedures were hernioplasty (42.96%) and cholecystectomy (34.81%). The preoperative fasting periods for solids and liquids were similar, median 16.50 (5.50-56.92) and 15.75 (2.50- 56.92) hours, respectively. The preoperative fasting period was influenced by the instruction received and surgery time. Postoperative fasting period was 15.67 (1.67-90.42) hours and was influenced by type of surgery and lack of synchrony between the clinical meeting and the nutrition and dietetics service schedules.

The potential toxic effects of Al to organs and tissues used in drugs commonly applied in dyspepsia as therapeutic, have been studied. Brain, liver, kidney and serum samples obtained from Wistar rats treated with two commercial Al complexes were studied and compared with equivalent samples collected from healthy animals receiving a placebo. The major alterations found, connected with the persistent intake of medicaments based on Al compounds, are relative to the accumulation of Al in liver and kidney. Also, the Al levels increase in brain and serum of rats supplemented with one of the Al complexes used. In the liver and kidney samples analyzed alterations in the Cu and Zn content levels were observed. Furthermore, a tendency to the decrease of Fe content in kidney and an increase of the Mn levels in brain is observed. The elemental alterations found are probably related to the intake of the drugs tested and are dependent on the type of the Al complex administered. The results obtained suggest that the long term use of these medicaments in the clinical practice should be thought over.

Although some animal models of food allergy in have already have been described, none of them uses the allergen in the animals' diet. This work describes the comparison between two developed models of food allergy in BALB/c mice, based in the administration of the allergen in the diet or by intragastric way. The experiment last for 28 days and the animals had been sensitized by means of subcutaneous injection in 1st and 14th days with in natura extract milk, bovine extract meat or frog extract meat. The experimental model that uses the allergen in the unbroken form presented morphometric alterations when compared with the one that used the heat treat allergen. It was noticed the existence of some more resistant proteins than others related to the denaturation, once compared the results of the two models; the differences had been more prominent for the milk and frog allergens. These results confirm the epidemiologic data of allergy incidence in the world's population. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA. All rights reserved.
