This is the third part of an article on the distribution of power and the nature of the state in Western industrialized societies and their implications in medicine. Parts I and II were published in the preceding issue of this Journal. Part I presented a critique of contemporary theories of the Western system of power; discussed the countervailing pluralist and power of elite theories, as well as those of bureaucratic and professional control; and concluded with an examination of the Marxist theories of economic determinism, structural determinism, and corporate statism. Part II presented a Marxist theory of the role, nature, and characteristics of state intervention. Part III focuses on the mode of that intervention and the reasons for its growth, with an added analysis of the attributes of state intervention in the health sector, and of the dialectical relationship between its growth and the current fiscal crisis of the state. In all three parts, the focus is on Western European countries and on North America, with many examples and categories from the area of medicine.

Notafilia is the study of paper money. Only a few countries in the world have issued banknotes with portraits of well-known scientists who brought international fame to their own people and medicine. PORTRAITS OF SCIENTISTS ON THE BANKNOTES OF YUGOSLAVIA, SERBIA AND MONTENEGRO AND SERBIA. Nikola Tesla and Mihailo Pupin Idvorski were the ingenious inventors and scientists of our time who made special contributions to radiology. Nikola Tesla (1856-1943) pioneered the use of X-rays for medical purposes, thus effectively laying the foundations of radiology and radiography, and revealed the existence of harmful effects of X-rays on the human body. Mihailo Pupin Idvorski (1854-1935) was worldwide famous for applying physics in practice, as well as in the basis of telephone and telegraph transmissions. He also studied the nature of X-rays and contributed to establishing of radiology. PORTRAITS OF SCIENTISTS ON THE BANKNOTES OF THE WORLD: Maria Sklodowska Curie (1867-1934) was the first woman to gain the academic title of the Academy of Medicine, Paris. Together with her husband Pierre Curie (1859-1906) she gave an outstanding contribution to science and medicine. The discovery of the radioactive elements introduced the concept of "radioactivity" into physics and "radiotherapy" as a new discipline in medicine, thus creating the conditions for the development of nuclear medicine, oncology, and mobile diagnostic radiology. This paper presents the banknotes featuring the portraits of Nikola Tesla, Mihailo Pupin Idvorski, Maria Sklodowska Curie and Pierre Curie, the world renowned scientists, who made enormous contributions to medicine and laid the foundation for radiology.

Commentary: Missing the elephant in my office: recommendations for part-time careers in academic medicine.

Science.gov (United States)

Helitzer, Deborah

2009-10-01

Several recent articles in this journal, including the article by Linzer and colleagues in this issue, discuss and promote the concept of part-time careers in academic medicine as a solution to the need to achieve a work-life balance and to address the changing demographics of academic medicine. The article by Linzer and colleagues presents the consensus of a task force that attempted to address practical considerations for part-time work in academic internal medicine. Missing from these discussions, however, are a consensus on the definition of part-time work, consideration of how such strategies would be available to single parents, how time or resources will be allocated to part-time faculty to participate in professional associations, develop professional networks, and maintain currency in their field, and how part-time work can allow for the development of expertise in research and scholarly activity. Most important, the discussions about the part-time solution do not address the root cause of dissatisfaction and attrition: the ever-increasing and unsustainable workload of full-time faculty. The realization that an academic full-time career requires a commitment of 80 hours per week begs the question of whether part-time faculty would agree to work 40 hours a week for part-time pay. The historical underpinnings of the current situation, the implications of part-time solutions for the academy, and the consequences of choosing part-time work as the primary solution are discussed. Alternative strategies for addressing some of the problems facing full-time faculty are proposed.

To determine the impact of Traditional Chinese Medicine on patients with chronic kidney disease (CKD). A total of 225 CKD patients in an outpatient department were recruited for this study, among whom 170 received regular Western and Chinese medicine treatments (control group) and 55 received treatments guided by the theory of Traditional Chinese Medicine (experimental group). The effectiveness of the treatments was determined through a pre-post comparison. Significant pre-intervention differences in age (P control group. No significant differences between the groups were found in changes of uric acid (P = 0.475), urine protein (P = 0.058), urine red cells (P = 0.577), and urine white cells (P = 0.01). A greater level of increase in estimated glomerular filtration rate was found in the experimental group compared with the control (P theory of Traditional Chinese Medicine can improve renal function through influencing glomerular filtration rate. The effect is more prominent than the regular treatment regime.

Despite the availability of more than 15 new "antiepileptic drugs", the proportion of patients with pharmacoresistant epilepsy has remained constant at about 20-30%. Furthermore, no disease-modifying treatments shown to prevent the development of epilepsy following an initial precipitating brain injury or to reverse established epilepsy have been identified to date. This is likely in part due to the polyetiologic nature of epilepsy, which in turn requires personalized medicine approaches. Recent advances in imaging, pathology, genetics, and epigenetics have led to new pathophysiological concepts and the identification of monogenic causes of epilepsy. In the context of these advances, the First International Symposium on Personalized Translational Epilepsy Research (1st ISymPTER) was held in Frankfurt on September 8, 2016, to discuss novel approaches and future perspectives for personalized translational research. These included new developments and ideas in a range of experimental and clinical areas such as deep phenotyping, quantitative brain imaging, EEG/MEG-based analysis of network dysfunction, tissue-based translational studies, innate immunity mechanisms, microRNA as treatment targets, functional characterization of genetic variants in human cell models and rodent organotypic slice cultures, personalized treatment approaches for monogenic epilepsies, blood-brain barrier dysfunction, therapeutic focal tissue modification, computational modeling for target and biomarker identification, and cost analysis in (monogenic) disease and its treatment. This report on the meeting proceedings is aimed at stimulating much needed investments of time and resources in personalized translational epilepsy research. This Part II includes the experimental and translational approaches and a discussion of the future perspectives, while the diagnostic methods, EEG network analysis, biomarkers, and personalized treatment approaches were addressed in Part I [1].

[Christian responsibility and experimental medicine. Experiments with and on humans, experiments on animals].

Science.gov (United States)

Grosse, Heinrich W

2002-01-01

The Jewish-Christian convictions that man was created as the image of God founded the "ethics of unavailability" which contrast with the utilitarian "ethics of interests." As man s nature is imperfect according to biblical understanding, those responsible in the field of experimental medicine should counteract all tendencies in society which promote an utopian definition of health and an eugenic mentality (idea of the "perfection of mankind"). Consequently, scientists must reflect their own image of man and the effects of their actions on this image. The goals of experimental medicine must also be examined under the aspect of fairness: do they only benefit a minority in the rich industrial nations? As in research on humans, the ethical evaluation of animal experiments must consider the question of the underlying image of humanity and the responsibility of mankind connected to it. Because of changes in society's values, the validity of traditional anthropocentrism is increasingly questioned. However, this does not affect the view of the special position of man as the bearer of responsibility. Even though there are different biblical statements on the relationship between man and animal, the Christian maxim to minimise violence towards animals can be derived from them. In the case of animal experiments this means: experiments which cause the animals severe suffering must be avoided by waiving the potential gain of knowledge from them. In general: in an ethical discussion on medical experiments using humans or animals, the public must be informed completely and involved effectively. A moratorium must be possible before plans become facts. Thinking about ethical problems in the area of experimental medicine should not be separated from the far-reaching questions about changes in our lifestyle and consumer behaviour.

Herbal medicine (HM) use is growing worldwide. Single herb preparations, ethnic and modern HM formulations are widely used as adjunct therapies or to improve consumer wellbeing. Areas covered: This final part in the publication series summarizes common tendencies in HM use as adjunct or alternative medicine, education of healthcare professionals and consumers, current and proposed guidelines regulating of production. We discuss potential HM-HM and HM-drug interactions that could lead to severe adverse events in situations where HMs are taken without proper medical professional oversight. Expert commentary: A number of serious problems have arisen with the steady global increase in HM use. HM interaction with conventional drugs (CD) may result in inadequate dosing of CD or adverse reactions; HM-HM interaction within herbal supplements could lead to toxicity of formulations. Inadequate education of clinicians and patients regarding medicinal properties of HMs must be addressed regionally and globally to ensure consumer safety.

Chaney, Kristin P; Macik, Maria L; Turner, Jacqueline S; Korich, Jodi A; Rogers, Kenita S; Fowler, Debra; Scallan, Elizabeth M; Keefe, Lisa M

Curricular review is considered a necessary component for growth and enhancement of academic programs and requires time, energy, creativity, and persistence from both faculty and administration. At Texas A&M College of Veterinary Medicine & Biomedical Sciences (TAMU), the faculty and administration partnered with the university's Center for Teaching Excellence to create a faculty-driven, data-enhanced curricular redesign process. The 8-step process begins with the formation of a dedicated faculty curriculum design team to drive the redesign process and to support the college curriculum committee. The next steps include defining graduate outcomes and mapping the current curriculum to identify gaps and redundancies across the curriculum. Data are collected from internal and external stakeholders including veterinary students, faculty, alumni, and employers of graduates. Data collected through curriculum mapping and stakeholder engagement substantiate the curriculum redesign. The guidelines, supporting documents, and 8-step process developed at TAMU are provided to assist other veterinary schools in successful curricular redesign. This is the first of a two-part report that provides the background, context, and description of the process for charting the course for curricular change. The process involves defining expected learning outcomes for new graduates, conducting a curriculum mapping exercise, and collecting stakeholder data for curricular evaluation (steps 1-4). The second part of the report describes the development of rubrics that were applied to the graduate learning outcomes (steps 5-8) and engagement of faculty during the implementation phases of data-driven curriculum change.

USE OF FRESH PARTS OF MEDICINAL PLANTS FOR HEALTH AND PRODUCTION IN LIVESTOCK – A NEW CONCEPT OF FARMING

Full Text Available Farm animals are reared for production to meet up the demand for animal protein in human. Various modern medicines are extensively used for production as well as treatment and prevention of diseases of animals, which can ultimately reach us through food chain. Herbs are now considered as an important source of alternative medicines. The Ayurvedic medicines prepared by manufacturers contain processed plant parts and added with preservative and other chemicals in many cases. The present way of research on herbal medicine follows the path of identification of active principles from the extracts of preserved parts of medicinal plants after testing of their efficacy in laboratory. This concept of research have the limitation of loss of many aromatic and other phytochemicals present in the living plant, which may have very important role when used together. Animals maintained in modern farm may be given relief from modern medicines in minor and moderate ailments, cure of problems related with their production with the validated fresh plant medicine available from the plants cultivated adjacent to the farm area. Consulting the reports of ethno-botanical study, a preliminary list of medicinal plant is prepared which are having antipyretic, analgesic, wound healing, immunostimulant, hepato-protective, fertility enhancing, pregnancy assisting, lactation assisting, anthelmintic, astringent, expectorant, purgative and anti-flatulent, nutriceutical, antiseptic, anti-dermatitis, anti-dysenteric and anti-enteric, hematenic, stomachic, diuretic and kidney stone removing effects and insecticidal or insect repelling effects. This list may be enriched further and plants may be selected for a farm from these groups according to the agro-climatic condition of the area, disease prevalence, problems encountered during farming practice and other requirements of the farm. Validation of reported effects of the plants is to be performed in fresh condition, so that parts

Extracts from IAEA's Resources Manual in Nuclear Medicine. Part-3: Establishing Nuclear Medicine Services

International Nuclear Information System (INIS)

2003-01-01

In the past, consideration was given to the categories of nuclear medicine ranging from simple imaging or in-vitro laboratories, to more complex departments performing a full range of in-vitro and in-vivo procedures that are also involved in advanced clinical services, training programmes, research and development. In developing countries, nuclear medicine historically has often been an offshoot of pathology, radiology or radiotherapy services. These origins are currently changing as less radioimmunoassay is performed and fully-fledged, independent departments of nuclear medicine are being set up. The trend appears to be that all assays (radioassay or ELISA) are done in a biochemistry laboratory whereas nuclear medicine departments are involved largely in diagnostic procedures, radionuclide therapy and non-imaging in-vitro tests. The level of nuclear medicine services is categorized according to three levels of need: Level 1: Only one gamma camera is needed for imaging purposes. The radiopharmaceutical supply, physics and radiation protection services are contracted outside the centre. Other requirements include a receptionist and general secretarial assistance. A single imaging room connected to a shared reporting room should be sufficient, with a staff of one nuclear medicine physician and one technologist, with back-up. This level is appropriate for a small private practice. Level 2: This is suitable for a general hospital where there are multiple imaging rooms where in-vitro and other non-imaging studies would generally be performed as well as radionuclide therapy. Level 3: his is appropriate for an academic institution where there is a need for a comprehensive clinical nuclear medicine service, human resource development and research programmes. Radionuclide therapy for in-patients and outpatients is provided

With this study, we aimed to document traditional uses of medicinal plants in the western part of Aladaglar/Nigde. This study was conducted between 2003 and 2005. The research area was in the western part of the Aladaglar mountains. The settlements in Aladaglar (5 towns and 10 villages) were visited during the field work. The plants collected by the help of medicinal plant users. The plants were identified and voucher specimens prepared. These voucher specimens were kept at the Herbarium of Istanbul University Faculty of Pharmacy (ISTE). We collected the information by means of semi-structured interviews with 170 informants (90 men and 80 women). In addition, the relative importance value of the species was determined and the informant consensus factor (FIC) was calculated for the medicinal plants researched in the study. According to the results of the identification, among 126 plants were used by the inhabitants and 110 species belonging to 40 families were used for medicinal purposes. Most of the medicinal plants used in Aladaglar/Nigde belong to the families Lamiaceae (25 species), Asteraceae (16 species), Apiaceae (7 species), Fabaceae (6 species) and Brassicaceae (5 species). The most commonly used plant species were Hypericum perforatumThymus sipyleus var. sipyleus, Rosa canina, Urtica dioica, Malva neglecta, Thymus leucotrichus, Salix alba, Mentha longifolia, Berberis crataegina, Juniperus oxycedrus, Viscum album subsp. abietis, Allium rotundum and Taraxacum stevenii. The most common preparations were infusion and decoction. The traditional medicinal plants have been mostly used for the treatment of cardiovascular diseases (86%), hemorrhoids (79%), urinary diseases (69%), diabetes (68%) and respiratory diseases (61%). The use of traditional medicine was still widespread among the inhabitants of Aladaglar mountains/Nigde region. Due to the lack of medical facilities in the villages of Aladaglar mountains, local people prefer herbal treatment rather than

Terror Medicine As Part of the Medical School Curriculum

Directory of Open Access Journals (Sweden)

Leonard A Cole

2014-09-01

Full Text Available Terror medicine, a field related to emergency and disaster medicine, focuses on medical issues ranging from preparedness to psychological manifestations specifically associated with terrorist attacks. Calls to teach aspects of the subject in American medical schools surged after the 2001 jetliner and anthrax attacks. Although the threat of terrorism persists, terror medicine is still addressed erratically if at all in most medical schools. This paper suggests a template for incorporating the subject throughout a 4-year medical curriculum. The instructional framework culminates in a short course for fourth year students, such as one recently introduced at Rutgers New Jersey Medical School, Newark, NJ. The proposed 4-year Rutgers curriculum serves as a model that could assist other medical schools contemplating the inclusion of terror medicine in pre-clerkship and clerkship training.

The gradual development of Chinese medicine is based on constant accumulation and summary of experience in clinical practice, but without the benefit of undergoing the experimental medicine stage. Although Chinese medicine has formed a systematic and unique theory system through thousands of years, with the development of evidence-based medicine, the bondage of the research methods of experience medicine to Chinese medicine is appearing. The rapid transition and transformation from experience medicine to evidence-based medicine have become important content in the development of Chinese medicine. According to the features of Chinese medicine, we propose the research idea of "taking two ways simultaneously," which is the study both in the ideal condition and in the real world. Analyzing and constructing the theoretical basis and methodology of clinical research in the real world, and building the stage for research technique is key to the effective clinical research of Chinese medicine. Only by gradually maturing and completing the clinical research methods of the real world could we realize "taking two ways simultaneously" and complementing each other, continuously produce scientific and reliable evidence of Chinese medicine, as well as transform and develop Chinese medicine from experience medicine to evidence-based medicine.

This paper is the continuation of Part I, which describes the high temperature and high pressure helium environment wear tests of graphite–graphite in frictional contact. In the present work, it has been attempted to simulate a Pebble Bed Reactor core environment as compared to Part I. The experimental apparatus, which is a custom-designed tribometer, is capable of performing wear tests at PBR relevant higher temperatures and pressures under a helium environment. This environment facilitates prediction of wear mass loss of graphite as dust particulates from the pebble bed. The experimental results of high temperature helium environment are used to anticipate the amount of wear mass produced in a pebble bed nuclear reactor.

Davorka Vrdoljak

2012-05-01

Full Text Available The concept of evidence based medicine (EBM as the integrationof clinical expertise, patient values and the best evidence was introduced by David Sackett in the 1980’s. Scientific literature in medicine is often marked by expansion, acummulation and quick expiration. Reading all important articles to keep in touch with relevant information is impossible. Finding the best evidence that answers a clinical question in general practice (GP in a short time is not easy. Five useful steps are described –represented by the acronym “5A+E”: assess, ask, acquire, appraise, apply and evaluate.The habit of conducting an evidence search “on the spot’’ is proposed. Although students of medicine at University of Split School of Medicine are taught EBM from the first day of their study and in all courses, their experience of evidence-searching and critical appraisal of the evidence, in real time with real patient is inadequate. Teaching the final-year students the practical use of EBM in a GP’s office is different and can have an important role in their professional development. It can positively impact on quality of their future work in family practice (or some other medical specialty by acquiring this habit of constant evidence-checking to ensure that best practice becomes a mechanism for life-long learning. Conclusion. EBM is a foundation stone of every branch of medicine and important part of Family Medicine as scientific and professional discipline. To have an EB answer resulting from GP’s everyday work is becoming a part of everyday practice.

Recent Advances in Antiepileptic Herbal Medicine.

Science.gov (United States)

Manchishi, Stephen M

2018-01-01

Epilepsy is one of the most common neurological disorders worldwide, with about 80 percent of cases thought to be in developing nations where it is mostly linked to superstition. The limited supply, high cost as well as low efficacy and adverse side effects of antiepileptic drugs (AEDs) is a matter of major concern. Herbal medicine has always been traditionally part of treatment of epilepsy. Herbal medicines are generally well tolerated, with fewer side effects. To highlight some herbal extracts that have been studied for their anticonvulsant activity in animal models, literature search from PubMed and Science Direct, was performed. The keywords for the search consisted of combinations of the following terms: Herbal antiepileptic and/or anticonvulsant, botanicals + epilepsy. Literature published in the last five years was considered. Eighteen (18) anticonvulsant herbal agents are reported and discussed. Experiments mostly consisted of phenotypic screens in rodents, with little diversity in screening methods. In most experiments, the tested extracts prolonged the time to onset of seizures and decreased their duration. Most experimenters implicate potentiation of GABAergic activity as the mode of action of the extracts, even though some experimenters did not fully characterise the bioactive chemical composition of their extracts. Potential herbal remedies have shown positive results in animal models. It remains unclear how many make it into clinical trials and eventually making part of the AED list. More rigorous research, applying strict research methodology with uniform herbal combinations, as well as clinical studies are urgently needed.

Astronomy, Astrology, and Medicine

Science.gov (United States)

Greenbaum, Dorian Gieseler

Astronomy and astrology were combined with medicine for thousands of years. Beginning in Mesopotamia in the second millennium BCE and continuing into the eighteenth century, medical practitioners used astronomy/astrology as an important part of diagnosis and prescription. Throughout this time frame, scientists cited the similarities between medicine and astrology, in addition to combining the two in practice. Hippocrates and Galen based medical theories on the relationship between heavenly bodies and human bodies. In an enduring cultural phenomenon, parts of the body as well as diseases were linked to zodiac signs and planets. In Renaissance universities, astronomy and astrology were studied by students of medicine. History records a long tradition of astrologer-physicians. This chapter covers the topic of astronomy, astrology, and medicine from the Old Babylonian period to the Enlightenment.

Chaotic non-planar vibrations of the thin elastica. Part I: Experimental observation of planar instability

Cusumano, J. P.; Moon, F. C.

1995-01-01

In this two-part paper, the results of an investigation into the non-linear dynamics of a flexible cantilevered rod (the elastica) with a thin rectangular cross-section are presented. An experimental examination of the dynamics of the elastica over a broad parameter range forms the core of Part I. In Part II, the experimental work is related to a theoretical study of the mechanics of the elastica, and the study of a two-degree-of-freedom model obtained by modal projection. The experimental system used in this investigation is a rod with clamped-free boundary conditions, forced by sinusoidally displacing the clamped end. Planar periodic motions of the driven elastica are shown to lose stability at distinct resonant wedges, and the resulting motions are shown in general to be non-planar, chaotic, bending-torsion oscillations. Non-planar motions in all resonances exhibit energy cascading and dynamic two-well phenomena, and a family of asymmetric, bending-torsion non-linear modes is discovered. Correlation dimension calculations are used to estimate the number of active degrees of freedom in the system.

Full Text Available Introduction: Aim of this review is to describe the recent applications of nuclear medicine techniques in diagnostics, particularly in oncology. Materials and methods: We reviewed scientific literature data searching for the current role of tomographic nuclear medicine techniques (SPECTand PET in oncology and summarized the main applications of these techniques. Results: Nuclear medicine techniques have a key role in oncology allowing early diagnosis of many tumours, an accurate staging of disease and evalutation of treatment response. Hybrid SPECT/CT and PET/CT imaging systems now provide metabolic and functional information from SPECTor PETcombined with the high spatial resolution and anatomic information of CT. The most frequent applications of SPECT/CT in oncology concern thyroid tumours, neuroendocrine tumours, bone metastases and lymph node mapping. Furthermore the evaluation of many tumours may benefit from PET/CT imaging. Discussion: The recent development of new radiopharmaceuticals and the growth of hybrid tomographic devices, such as SPECT/CT and PET/CT, now permits molecular imaging of biologic processes at the cellular level to improve both the diagnosis and treatment of many tumours.

Sports medicine is a profession pertaining to primary health care of sport population (competitors, coaches, referees, participants in sports recreation). It embraces the physical and mental health protection and promotion of participants in relation to a particular sport activity and sport environment, directing athletes to a sport and adapting them to sport and the sport to them. Sports medicine takes part in selection procedure, training process planning and programming, and cares for epidemiological, hygienic, nutritional and other problems in sport. The Republic of Croatia belongs to those world states in which the field of sports medicine is regulated neither by a law or by profession. A consequence is that wide circle of physicians and paramedics work in clubs and various medical units without any legal or/and professional control not being adequately educated nor having licence for it. This review is an appeal to the Croatian Medical Chamber and the Ministry of Health to make efforts to promote the education and medical profession in sports medicine.

Full Text Available Objective: To explore the effects of combined therapy of traditional Chinese medicine and western medicine on platelets, coagulative functions and inflammatory cytokines in patients with ulcerative colitis (UC. Methods: A total of 267 patients with UC were collected. 137 patients were treated with combined therapy of traditional Chinese medicine and western medicine as experimental group and 130 patients were treated with only western medicine as controls. Platelet count, coagulation function indexes and inflammatory cytokines were measured before and 15 d after the treatment. Results: No significantly differences were found in all indexes before treatment between two groups. After different treatments, platelet count (PLT, platelet distribution width (PDW were significantly decreased in both groups, but mean platelet volumn (MPV were significantly increased than before treatment. PLT and PDW were significantly lower and MPV were significantly higher in experimental group than control group. Fibrinogen (Fib and D-dimer (DD decreased significantly after treatment. Fib and DD in experimental group were significantly lower than controls. No significantly differences were found in activated partial thromboplastin time (APTT and prothrobin time (PT. Tumor necrosisi factor-α (TNF-α, interleukin-6 (IL-6 and interleukin-8 (IL-8 decreased significantly in both group after treatment. TNF-毩, IL-6 and IL-8 were significantly lower in experimental group than controls. Conclusion: Combined therapy of traditional Chinese medicine and western medicine can more effectively improve the cogulation, fibrinolysis and inflammation in patients with UC than only western medicine therapy.

Over the last centuries, there were many important discoveries in medicine that were crucial for gaining a better understanding of several physiological processes. Molecular modelling techniques are powerful tools that have been successfully used to analyse and interface medicinal chemistry studies with electrochemical experimental results. This special combination can help to comprehend medicinal chemistry problems, such as predicting biological activity and understanding drug action mechanisms. Electrochemistry has provided better comprehension of biological reactions and, as a result of many technological improvements, the combination of electrochemical techniques and biosensors has become an appealing choice for pharmaceutical and biomedical analyses. Therefore, this review will briefly outline the present scope and future advances related to the integration of electrochemical and medicinal chemistry approaches based on various applications from recent studies.

Diplazium esculentum is a widely used medicinal fern in Malaysia and other regions worldwide. Heavy metals in plants should be determined because prolonged human intake of toxic trace elements, even at low doses, results in organ malfunction and causes chronic toxicity. Hence, substantial information should be obtained from plants that grow on soils containing high concentrations of heavy metals. This study aimed to determine the physicochemical characteristics of soil and heavy metal concentrations (Pb, Cr, Mn, Cu, and Zn) in different parts of D. esculentum and soil, which were collected from the fern garden of Universiti Kebangsaan Malaysia. Results showed that heavy metals were highly accumulated in D. esculentum roots.

The presence of hair plays an important role in people's overall physical appearance and self-perception. As a result of increased life expectancy, the desire to look youthful plays a bigger role than ever.The use of medicinal plants is as old as mankind and the market will face many new products containing natural oils and herbs in coming years. In traditional Iranian medicine, many plants and herbal formulations are reported for hair growth as well as the improvement in hair quality. The aim of this article is to introduce effective medicinal plants in traditional Iranian medicine to prevent gray hair and advocate them as the new products. The present investigation is an overview study and has been codified by library search in the main sources of traditional Iranian medicine. In traditional Iranian medicine, three types of formulations are proposed to prevent gray hair, namely (i) treatment compounds, (ii) preventive compounds, and (iii) hair dyes to color gray hairs. Our search showed that the main parts of a plant that is used in the treatment and preventive compounds are seeds and fruits. These are primarily in the form of topical oil or oral compound (electuary). The majority of plant parts used in hair dyes is from the fruit and/or leaves. Natural products are highly popular and the use of plant extracts in formulations is on the rise. This is because synthetic based product may cause health hazards with several side effects. Considering the increased popularity of herbal drugs in hair care, it is worthwhile to conduct systemic investigation on the production and efficacy of these drugs. We trust that our investigation would encourage the use of traditional Iranian medicine in future hair care products.

Poor access to essential medicines is common in many low- and middle-income countries, partly due to an insufficient and inadequately trained workforce to manage the medicines supply chain. We conducted a prospective impact evaluation of the training and deployment of pharmacy assistants (PAs) to rural health centers in Malawi. A quasi-experimental design was used to compare access to medicines in two districts where newly trained PAs were deployed to health centers (intervention) and two districts with no trained PAs at health centers (comparison). A baseline household survey and two annual post-intervention household surveys were conducted. We studied children under five years with a history of fever, cough and difficulty in breathing, and diarrhea in the previous two weeks. We collected data on access to antimalarials, antibiotics and oral rehydration salts (ORS) during the childrens' symptomatic periods. We used difference-in-differences regression models to estimate the impact of PA training and deployment on access to medicines. We included 3974 children across the three rounds of annual surveys: 1840 (46%) in the districts with PAs deployed at health centers and 2096 (53%) in districts with no PAs deployed at health centers. Approximately 80% of children had a fever, nearly 30% had a cough, and 43% had diarrhea in the previous two weeks. In the first year of the program, the presence of a PA led to a significant 74% increase in the odds of access to any antimalarial, and a significant 49% increase in the odds of access to artemisinin combination therapies. This effect was restricted to the first year post-intervention. There was no effect of presence of a PA on access to antibiotics or ORS. The training and deployment of pharmacy assistants to rural health centers in Malawi increased access to antimalarial medications over the first year, but the effect was attenuated over the second year. Pharmacy assistants training and deployment demonstrated no impact on

Few studies have investigated placebo and nocebo effects in a human sexuality context. Studying placebo and nocebo responses in this context may provide insight into their potential to modulate sexual drive and function. To examine such effects in sexual medicine, 48 healthy, male heterosexual participants were divided into four groups. Each group received instruction to expect stimulating effects, no effect, or an inhibitory effect on sexual functions. Only one group received the dopamine agonist cabergoline; all other groups received placebo or nocebo. Modulations in sexual experience were examined through an established experimental paradigm of sexual arousal and masturbation-induced orgasm during erotic film sequences with instruction to induce placebo or nocebo effects. Endocrine data, appetitive, consummatory, and refractory sexual behavior parameters were assessed using the Arizona Sexual Experience Scale (ASEX) and the Acute Sexual Experience Scale (ASES). Results showed increased levels of sexual function after administration of cabergoline with significant effects for several parameters. Placebo effects were induced only to a small degree. No negative effects on sexual parameters in the nocebo condition were noted. This paradigm could induce only small placebo and nocebo effects. This supports the view that healthy male sexual function seems relatively resistant to negative external influences.

Full Text Available Abstract Background The Kagera region of north western Tanzania has a rich culture of traditional medicine use and practices. The dynamic inter-ethnic interactions of different people from the surrounding countries constitute a rich reservoir of herbal based healing practices. This study, the second on an ongoing series, reports on the medicinal plant species used in Katoro ward, Bukoba District, and tries to use the literature to establish proof of the therapeutic claims. Methodology Ethnomedical information was collected using Semi-structured interviews in Kyamlaile and Kashaba villages of Katoro, and in roadside bushes on the way from Katoro to Bukoba through Kyaka. Data collected included the common/local names of the plants, parts used, the diseases treated, methods of preparation, dosage, frequency and duration of treatments. Information on toxicity and antidote were also collected. Literature was consulted to get corroborative information on similar ethnomedical claims and proven biological activities of the plants. Results Thirty three (33 plant species for treatement of 13 different disease categories were documented. The most frequently treated diseases were those categorized as specific diseases/conditions (23.8% of all remedies while eye diseases were the least treated using medicinal plants (1.5% of all remedies. Literature reports support 47% of the claims including proven anti-malarial, anti-microbial and anti-inflammatory activity or similar ethnomedical uses. Leaves were the most frequently used plant part (20 species followed by roots (13 species while making of decoctions, pounding, squeezing, making infusions, burning and grinding to powder were the most common methods used to prepare a majority of the therapies. Conclusion Therapeutic claims made on plants used in traditional medicine in Katoro ward of Bukoba district are well supported by literature, with 47% of the claims having already been reported.

Abstract Objective To examine trends in family medicine training at a time when substantial pedagogic change is under way, focusing on factors that relate to extended family medicine training. Design Aggregate-level secondary data analysis based on the Canadian Post-MD Education Registry. Setting Canada. Participants All Canadian citizens and permanent residents who were registered in postgraduate family medicine training programs within Canadian faculties of medicine from 1995 to 2013. Main outcome measures Number and proportion of family medicine residents exiting 2-year and extended (third-year and above) family medicine training programs, as well as the types and numbers of extended training programs offered in 2015. Results The proportion of family medicine trainees pursuing extended training almost doubled during the study period, going from 10.9% in 1995 to 21.1% in 2013. Men and Canadian medical graduates were more likely to take extended family medicine training. Among the 5 most recent family medicine exit cohorts (from 2009 to 2013), 25.9% of men completed extended training programs compared with 18.3% of women, and 23.1% of Canadian medical graduates completed extended training compared with 13.6% of international medical graduates. Family medicine programs vary substantially with respect to the proportion of their trainees who undertake extended training, ranging from a low of 12.3% to a high of 35.1% among trainees exiting from 2011 to 2013. Conclusion New initiatives, such as the Triple C Competency-based Curriculum, CanMEDS–Family Medicine, and Certificates of Added Competence, have emerged as part of family medicine education and credentialing. In acknowledgment of the potential effect of these initiatives, it is important that future research examine how pedagogic change and, in particular, extended training shapes the care family physicians offer their patients. As part of that research it will be important to measure the breadth and uptake of

This work is carried out under cost-sharing contract with European Atomic Energy Community in the framework of its programme on Management and Storage of Radioactive Wastes. Part 1: PMATCH, A Program to Manage Thermochemical Data, describes the development and use of a computer program, by means of which new thermodynamic data from literature may be referenced to a common frame and thereby become internally consistent with an existing database. The report presents the relevant thermodynamic expressions and their use in the program is discussed. When there is not sufficient thermodynamic data available to describe a species behaviour under all conceivable conditions, the problems arising are thoroughly discussed and the available data is handled by approximating expressions. Part II: The Experimental Validation of Geochemical Computer models are the results of experimental investigations of the equilibria established in aqueous suspensions of mixtures of carbonate minerals (Calcium, magnesium, manganese and europium carbonates) compared with theoretical calculations made by means of the geochemical JENSEN program. The study revealed that the geochemical computer program worked well, and that its database was of sufficient validity. However, it was observed that experimental difficulties could hardly be avoided, when as here a gaseous component took part in the equilibria. Whereas the magnesium and calcium carbonates did not demonstrate mutual solid solubility, this produced abnormal effects when manganese and calcium carbonates were mixed resulting in a diminished solubility of both manganese and calcium. With tracer amounts of europium added to a suspension of calcite in sodium carbonate solutions long term experiments revealed a transition after 1-2 months, whereby the tracer became more strongly adsorbed onto calcite. The transition is interpreted as the nucleation and formation of a surface phase incorporating the 'species' NaEu(Co 3 ) 2

Piper umbellatum L. (Piperaceae) is a shrub found in the Amazon, Savannah and Atlantic Forest region of Brazil. It is widely used in folk medicine in many countries primarily for the treatment of gastric disorders. The aim of this study was to evaluate the gastroprotective and anti-ulcer effects of hydroethanolic extract of P. umbellatum (HEPu) leaves in experimental rodents. In addition, the anti-Helicobacter pylori activity of the extract was assessed. The leaves of P. umbellatum were macerated in 75% (1:3w/v) hydroethanolic solution to obtain HEPu. The gastroprotective and ulcer healing activities of HEPu were evaluated using acidified ethanol (acute) and acetic acid (chronic) gastric ulcer models in rodents. The anti-H. pylori activity was evaluated by in vitro broth microdilution assay using H. pylori cagA + and vacA + strain. The probable mechanism of action of HEPu was evaluated by determining gastric secretory parameters, antioxidant enzyme (catalase), non-protein sulfhydryl (glutathione) and malondialdehyde levels in gastric tissue, including pro-inflammatory (IL-1β, TNF-a, IL -17, RANTES, IFN-γ and MIP-2) and anti-inflammatory (IL-10) cytokines. HEPu demonstrated potent gastroprotection against acute ulcer induced by acidified ethanol and excellent healing effect of the chronic ulcer induced by acetic acid. The gastroprotective activity in acidified ethanol is partly attributed to the antioxidant mechanisms, while anti-secretory, anti-inflammatory and regeneration of the gastric mucosa are evoked as part of its antiulcer mechanism of action. The gastric ulcer healing of HEPu also involves restoration of the altered cytokines levels to near normal. However, it has no in vitro anti-H. pylori activity. The results of this study showed that HEPu possesses preventive and curative effects in experimental models of gastric ulcers in animals. These effects are partially dependent on antioxidant, antisecretory, anti-inflammatory and mucosa regeneration. It is

Like health care systems in other developed countries, Japan's health care system faces significant challenges due to aging of the population and economic stagnation. Advanced medicine (Senshin Iryou) is a unique system of medical care in Japan offering highly technology-driven medical care that is not covered by public health insurance. Advanced medicine has recently developed and expanded as part of health care reform. Will it work? To answer this question, we briefly trace the historical development of advanced medicine and describe the characteristics and current state of advanced medical care in Japan. We then offer our opinions on the future of advanced medicine with careful consideration of its pros and cons. We believe that developing advanced medicine is an attempt to bring health care reform in line rather than the goal of health care reform.

Chinese medicine is a historic cultural legacy of China. It has made a significant contribution to medicine and healthcare for generations. The development of Chinese herbal medicine analysis is emphasized by the Chinese pharmaceutical industry. This study has carried out the experimental analysis of ten kinds of Chinese herbal powder including Fritillaria powder, etc., based on the photoacoustic spectroscopy (PAS) method. First, a photoacoustic spectroscopy system was designed and constructed, especially a highly sensitive solid photoacoustic cell was established. Second, the experimental setup was verified through the characteristic emission spectrum of the light source, obtained by using carbon as a sample in the photoacoustic cell. Finally, as the photoacoustic spectroscopy analysis of Fritillaria, etc., was completed, the specificity of the Chinese herb medicine analysis was verified. This study shows that the PAS can provide a valid, highly sensitive analytical method for the specificity of Chinese herb medicine without preparing and damaging samples.

Influence of Hydraulic Design on Stability and on Pressure Pulsations in Francis Turbines at Overload, Part Load and Deep Part Load based on Numerical Simulations and Experimental Model Test Results

International Nuclear Information System (INIS)

Magnoli, M V; Maiwald, M

2014-01-01

Francis turbines have been running more and more frequently in part load conditions, in order to satisfy the new market requirements for more dynamic and flexible energy generation, ancillary services and grid regulation. The turbines should be able to be operated for longer durations with flows below the optimum point, going from part load to deep part load and even speed-no-load. These operating conditions are characterised by important unsteady flow phenomena taking place at the draft tube cone and in the runner channels, in the respective cases of part load and deep part load. The current expectations are that new Francis turbines present appropriate hydraulic stability and moderate pressure pulsations at overload, part load, deep part load and speed-no-load with high efficiency levels at normal operating range. This study presents series of investigations performed by Voith Hydro with the objective to improve the hydraulic stability of Francis turbines at overload, part load and deep part load, reduce pressure pulsations and enlarge the know-how about the transient fluid flow through the turbine at these challenging conditions. Model test measurements showed that distinct runner designs were able to influence the pressure pulsation level in the machine. Extensive experimental investigations focused on the runner deflector geometry, on runner features and how they could reduce the pressure oscillation level. The impact of design variants and machine configurations on the vortex rope at the draft tube cone at overload and part load and on the runner channel vortex at deep part load were experimentally observed and evaluated based on the measured pressure pulsation amplitudes. Numerical investigations were employed for improving the understanding of such dynamic fluid flow effects. As example for the design and experimental investigations, model test observations and pressure pulsation curves for Francis machines in mid specific speed range, around n qopt = 50

Sauve, R.G.; Morandin, G.D.; Nadeau, E.

In a number of applications, the hydrodynamic effect of a fluid must be included in the structural evaluation of liquid-filled vessels undergoing transient loading. Prime examples are liquid radioactive waste transportation packages. These packages must demonstrate the ability to withstand severe accidental impact scenarios. A hydrodynamic model of the fluid is developed using a finite element discretization of the momentum equations for a three-dimensional continuum. An inviscid fluid model with an isotropic stress state is considered. A barotropic equation of state, relating volumetric strain to pressure, is used to characterize the fluid behavior. The formulation considers the continuum as a compressible medium only, so that no tension fields are permitted. The numerical technique is incorporated into the existing general-purpose three-dimensional structural computer code H3DMAP. Part 1 of the paper describes the theory and implementation along with comparisons with classical theory. Part 2 describes the experimental validation of the theoretical approach. Excellent correlation between predicted and experimental results is obtained

The foundation for a new era of data-driven medicine has been set by recent technological advances that enable the assessment and management of human health at an unprecedented level of resolution-what we refer to as high-definition medicine. Our ability to assess human health in high definition is enabled, in part, by advances in DNA sequencing, physiological and environmental monitoring, advanced imaging, and behavioral tracking. Our ability to understand and act upon these observations at equally high precision is driven by advances in genome editing, cellular reprogramming, tissue engineering, and information technologies, especially artificial intelligence. In this review, we will examine the core disciplines that enable high-definition medicine and project how these technologies will alter the future of medicine. Copyright © 2017 Elsevier Inc.

2017-11-01

An official medicines control laboratory (OMCL) provides an important contribution to combat counterfeit and illegal medicines. The OMCL supports the competent authorities in controlling the quality of authorised medicinal products in the legal supply chain. For detecting counterfeit medicines in the legal supply chain, a risk-based approach in choice of products is conducted. Furthermore, the OMCL analyses suspicious medicines from the illegal supply chain for any other authority. The chemical analysis of a suspicious sample is needed to identify such a sample as a counterfeit medicine. The analytical results are fundamental for the evaluation of the legal status of the product and for the assessment of it's inherent hazard to public health. The global market of illegal medicines is rapidly changing. Therefore a good national and international working liaison and co-operation between laboratories and authorities is obligatory to protect public health. The OMCL provides important knowledge of new trends in counterfeit and illegal medicines. Hence, it is an essential part in surveillance of medicinal products. The efficient networking enables prompt official interventions. Thus, risks for the public health by substandard medicines were reduced. Beside the chemical analysis, the OMCL can help to raise public awareness about counterfeit and illegal medicines. In Germany, the risk of counterfeit medicines reaching patients through the legal supply chain is still low, but the possibility cannot be ignored.

Nuclear medicine is a specialized area of radiology that uses very small amounts of radioactive materials to examine organ function and structure. Nuclear medicine is older than CT, ultrasound and MRI. It was first used in patients over 60-70 years ago. Today it is an established medical specialty and offers procedures that are essential in many medical specialities like nephrology, pediatrics, cardiology, psychiatry, endocrinology and oncology. Nuclear medicine refers to medicine (a pharmaceutical) that is attached to a small quantity of radioactive material (a radioisotope). This combination is called a radiopharmaceutical. There are many radiopharmaceuticals like DTPA, DMSA, HIDA, MIBI and MDP available to study different parts of the body like kidneys, heart and bones etc. Nuclear medicine uses radiation coming from inside a patient's body where as conventional radiology exposes patients to radiation from outside the body. Thus nuclear imaging study is a physiological imaging, whereas diagnostic radiology is anatomical imaging. It combines many different disciplines like chemistry, physics mathematics, computer technology, and medicine. It helps in diagnosis and to treat abnormalities very early in the progression of a disease. The information provides a quick and accurate diagnosis of wide range of conditions and diseases in a person of any age. These tests are painless and most scans expose patients to only minimal and safe amounts of radiation. The amount of radiation received from a nuclear medicine procedure is comparable to, or often many times less than, that of a diagnostic X-ray. Nuclear medicine provides an effective means of examining whether some tissues/organs are functioning properly. Therapy using nuclear medicine in an effective, safe and relatively inexpensive way of controlling and in some cases eliminating, conditions such as overactive thyroid, thyroid cancer and arthritis. Nuclear medicine imaging is unique because it provides doctors with

The purpose of this review is to explore what problems in medicine might benefit from such learning approaches and use examples from the literature to introduce basic concepts in machine learning. It is important to note that seemingly large enough medical data sets and adequate learning algorithms have been available for many decades, and yet, although there are thousands of papers applying machine learning algorithms to medical data, very few have contributed meaningfully to clinical care. This lack of impact stands in stark contrast to the enormous relevance of machine learning to many other industries.

(Apiaceae are three well-known medicinal plants from the Libyan flora, which have long been used for the treatment of inflammations. The aim of the present study was to investigate, for the first time, the anti-inflammatory property of the methanol (MeOH extracts of the aerial parts of these plants. Shade-dried and ground aerial parts of B. pseudodictamnus, S. fruticosa and T. garganica were Soxhlet-extracted with MeOH. The extracts were concentrated by evaporation under reduced pressure at 40°C. The anti-inflammatory activity of the extracts was evaluated using the carrageenan-induced mice paw edema model. The administration of the extracts at a dose of 500 mg/kg body weight produced statistically significant inhibition (p < 0.05 of edema within 3 h of carrageenan administration. The results demonstrated significant anti-inflammatory properties of the test extracts. Among the extracts, the S. fruticosa extract exhibited the most significant inhibition of inflammation after 3 h (62.1%. Thus, S. fruticosa could be a potential source for the discovery and development of newer anti-inflammatory ‘leads’ for drug development. The anti-inflammatory activity of B. pseudodictamnus and S. fruticosa could be assumed to be related to high levels of phenolic compounds, e.g., flavonoids, present in these plants.

Pedemonte, A.A.; Traverso, A.; Massardo, A.F.

2008-01-01

One of the most interesting methods of water introduction in a gas turbine circuit is represented by the humid air turbine cycle (HAT). In the HAT cycle, the humidification can be provided by a pressurised saturator (i.e. humidification tower or saturation tower), this solution being known to offer several attractive features. This part A is focused on an experimental study of a pressurised humidification tower, with structured packing inside. After a description of the test rig employed to carry out the measuring campaign, the results relating to the thermodynamic process are presented and discussed. The experimental campaign was carried out over 162 working points, covering a relatively wide range of possible operating conditions. Details about measured data are provided in the appendix. It is shown that the saturator's behaviour, in terms of air outlet humidity and temperature, is primarily driven by, in decreasing order of relevance, the inlet water temperature, the inlet water over inlet dry air mass flow ratio and the inlet air temperature. Finally, the exit relative humidity is shown to be consistently over 100%, which may be explained partially by measurement accuracy and droplet entrainment, and partially by the non-ideal behaviour of air-steam mixtures close to saturation

Differences in the origin of philosophy between Chinese medicine and Western medicine: Exploration of the holistic advantages of Chinese medicine.

2013-09-01

To explore advantages of Chinese medicine (CM) by analyzing differences in the origin of philosophy for human health between CM and Western medicine (WM). Methodologically, a distinctive feature of CM is its systems theory, which is also the difference between CM and WM. Since the birth of CM, it has taken the human body as a whole from the key concepts of "qi, blood, yin-yang, viscera (Zang-Fu), and meridian and channel", rather than a single cell or a particular organ. WM evolves from the Western philosophic way of thinking and merely uses natural sciences as the foundation. The development of WM is based on human structures, or anatomy, and therefore, research of WM is also based on the way of thinking of decomposing the whole human body into several independent parts, which is the impetus of promoting the development of WM. The core of CM includes the holistic view and the dialectical view. Chinese herbal medicines contain various components and treat a disease from multiple targets and links. Therefore, Chinese herbal medicines treat a diseased state by regulating and mobilizing the whole body rather than just regulating a single factor, since the diseased state is not only a problem in a local part of the body but a local reflection of imbalance of the whole body.

India has the distinction of financing its healthcare mainly through out-of-pocket expenses by individual families contributing to catastrophic health expenditure and impoverishment. Nearly 70 % of the expenditure is on medicines purchased at private pharmacies. Patients with chronic ailments are especially affected, as they often need lifelong medicines. Over the past years in India, there have been several efforts to improve drug availability at government primary health centres. In this study, we aim to understand health system factors that affect utilisation and access to generic medicines for people with non-communicable diseases. This study aims to understand if (and how) a package of interventions targeting primary health centres and community participation platforms affect utilisation and access to generic medicines for people with non-communicable diseases in the current district context in India. This study will employ a quasi-experimental design and a qualitative theory-driven approach. PHCs will be randomly assigned to one of three arms of the intervention. In one arm, PHCs will receive inputs to optimise service delivery for non-communicable diseases, while the second arm will receive an additional package of interventions to strengthen community participation platforms for improving non-communicable disease care. The third arm will be the control. We will conduct household and facility surveys, before and after the intervention and will estimate the effect of the intervention by difference-in-difference analysis. Sample size for measuring effects was calculated based on obtaining at least 30 households for each primary health centre spread across three distance-based clusters. Primary outcomes include availability and utilisation of medicines at primary health centres and out-of-pocket expenditure for medicines by non-communicable disease households. Focus group discussions with patients and in-depth interviews with health workers will also be

Nikola Tesla (1856- 1943) was a genius inventor and scientist, whose contribution to medicine is remarkable. Part I of this article reviewed special contributions of the world renowned scientist to the establishment of radiology as a new discipline in medicine. This paper deals with the use of Tesla currents in medicine. Tesla Currents in Medicine. Tesla's greatest impact on medicine is his invention of a transformer (Tesla coil) for producing high frequency and high voltage currents (Tesla currents). Tesla currents are used in diathermy, as they, while passing through the body, transform electrical energy into a therapeutic heat. In 1891, Tesla passed currents through his own body and was the first to experience their beneficial effects. He kept correspondence on electrotherapy with J. Dugan and S. H. Monell. In 1896, he used high frequency currents and designed an ozone generator for producing ozone, with powerful antiseptic and antibacterial properties. Tesla is famous for his extensive experiments with mechanical vibrations and resonance, examining their effects on the organ ism and pioneering their use for medical purposes. Tesla also designed an oscillator to relieve fatigue of the leg muscles. It is less known that Tesla's inventions (Tesla coil and wireless remote control) are widely used in modern medical equipment. Apart from this, wireless technology is nowadays widely applied in numerous diagnostic and therapeutic procedures. Nikola Tesla was the last Renais- sance figure of the modern era. Tesla bridged three centuries and two millennia by his inventions, and permanently indebted humankind by his epochal discoveries.

Ethiopia is endowed with abundant medicinal plant resources and traditional medicinal practices. However, available research evidence on indigenous anti-malarial plants is highly fragmented in the country. The present systematic review attempted to explore, synthesize and compile ethno-medicinal research evidence on anti-malarial medicinal plants in Ethiopia. A systematic web search analysis and review was conducted on research literature pertaining to medicinal plants used for traditional malaria treatment in Ethiopia. Data were collected from a total of 82 Ethiopian studies meeting specific inclusion criteria including published research articles and unpublished thesis reports. SPSS Version 16 was used to summarize relevant ethno-botanical/medicinal information using descriptive statistics, frequency, percentage, tables, and bar graphs. A total of 200 different plant species (from 71 families) used for traditional malaria treatment were identified in different parts of Ethiopia. Distribution and usage pattern of anti-malarial plants showed substantial variability across different geographic settings. A higher diversity of anti-malarial plants was reported from western and southwestern parts of the country. Analysis of ethno-medicinal recipes indicated that mainly fresh leaves were used for preparation of remedies. Decoction, concoction and eating/chewing were found to be the most frequently employed herbal remedy preparation methods. Notably, anti-malarial herbal remedies were administered by oral route. Information on potential side effects of anti-malarial herbal preparations was patchy. However, some anti-malarial plants were reported to have potentially serious side effects using different local antidotes and some specific contra-indications. The study highlighted a rich diversity of indigenous anti-malarial medicinal plants with equally divergent herbal remedy preparation and use pattern in Ethiopia. Baseline information gaps were observed in key geographic

Medical humanities' challenge to medicine.

Science.gov (United States)

Macnaughton, Jane

2011-10-01

Medicine is predicated on a view of human nature that is highly positivist and atomistic. This is apparent in the way in which its students are taught, clinical consultations are structured and medical evidence is generated. The field of medical humanities originally emerged as a challenge to this overly narrow view, but it has rarely progressed beyond tinkering around the edges of medical education. This is partly because its practitioners have largely been working from within a pervasive medical culture from which it is difficult to break free, and partly because the field has been insufficiently armed with scholarly thinking from the humanities. This is beginning to change and there is a sign that research in medical humanities has the potential to mount a persuasive challenge to medicine's ways of teaching, working and finding out. This article problematizes medicine's narrow viewpoint, grounding its critique in philosophical ideas from phenomenology and pragmatism. I will reflect upon the historical context within which medical humanities has emerged and briefly examine specific examples of how its interdisciplinary approach, involving humanities scholars with clinicians and medical scientists, may develop new research directions in medicine. © 2011 Blackwell Publishing Ltd.

Radiopharmaceuticals are nowadays under the responsibility of the radio-pharmacist because of their medicinal product status. Radiopharmacy belongs to the hospital pharmacy department, nevertheless, interactions with nuclear medicine department are important: rooms are included or located near nuclear medicine departments in order to respect radiation protection rules, more over staff, a part of the material and some activities are shared between the two departments. Consequently, it seems essential to formalize links between the radiopharmacy and the nuclear medicine department, setting the goals to avoid conflicts and to ensure patients' security. Modalities chosen for this formalization will depend on the establishment's organization. (authors)

Review of Anti-Inflammatory Herbal Medicines

2016-01-01

Full Text Available Medicinal plants and their secondary metabolites are progressively used in the treatment of diseases as a complementary medicine. Inflammation is a pathologic condition that includes a wide range of diseases such as rheumatic and immune-mediated conditions, diabetes, cardiovascular accident, and etcetera. We introduce some herbs which their anti-inflammatory effects have been evaluated in clinical and experimental studies. Curcuma longa, Zingiber officinale, Rosmarinus officinalis, Borago officinalis, evening primrose, and Devil’s claw are some of the introduced medicinal herbs in this review. Since the treatment of inflammation is not a one-dimensional remedy, this review tries to reach a multidimensional therapeutic approach to inflammation with the help of herbal medicine and modification in lifestyle.

Purpose: Since drug responses vary between patients, it is crucial to develop pre-clinical or co-clinical strategies that forecast patient response. In this study, we tested whether RNA-based therapeutics were suitable for personalized medicine by using patient-derived-organoid (PDO) and patient-derived-xenograft (PDX) models. Experimental Design: We performed microRNA (miRNA) profiling of PDX samples to determine the status of miRNA deregulation in individual pancreatic ductal adenocarcinoma (PDAC) patients. To deliver personalized RNA-based-therapy targeting oncogenic miRNAs that form part of this common PDAC miRNA over-expression signature, we packaged antimiR oligonucleotides against one of these miRNAs in tumor-penetrating nanocomplexes (TPN) targeting cell surface proteins on PDAC tumors. Results: As a validation for our pre-clinical strategy, the therapeutic potential of one of our nano-drugs, TPN-21, was first shown to decrease tumor cell growth and survival in PDO avatars for individual patients, then in their PDX avatars. Conclusions: This general approach appears suitable for co-clinical validation of personalized RNA medicine and paves the way to prospectively identify patients with eligible miRNA profiles for personalized RNA-based therapy.

Nicolet, C; Zobeiri, A; Maruzewski, P; Avellan, F

2010-01-01

The swirling flow developing in Francis turbine draft tube under part load operation leads to pressure fluctuations usually in the range of 0.2 to 0.4 times the runner rotational frequency resulting from the so-called vortex breakdown. For low cavitation number, the flow features a cavitation vortex rope animated with precession motion. Under given conditions, these pressure fluctuations may lead to undesirable pressure fluctuations in the entire hydraulic system and also produce active power oscillations. For the upper part load range, between 0.7 and 0.85 times the best efficiency discharge, pressure fluctuations may appear in a higher frequency range of 2 to 4 times the runner rotational speed and feature modulations with vortex rope precession. It has been pointed out that for this particular operating point, the vortex rope features elliptical cross section and is animated of a self-rotation. This paper presents an experimental investigation focusing on this peculiar phenomenon, defined as the upper part load vortex rope. The experimental investigation is carried out on a high specific speed Francis turbine scale model installed on a test rig of the EPFL Laboratory for Hydraulic Machines. The selected operating point corresponds to a discharge of 0.83 times the best efficiency discharge. Observations of the cavitation vortex carried out with high speed camera have been recorded and synchronized with pressure fluctuations measurements at the draft tube cone. First, the vortex rope self rotation frequency is evidenced and the related frequency is deduced. Then, the influence of the sigma cavitation number on vortex rope shape and pressure fluctuations is presented. The waterfall diagram of the pressure fluctuations evidences resonance effects with the hydraulic circuit. The time evolution of the vortex rope volume is compared with pressure fluctuations time evolution using image processing. Finally, the influence of the Froude number on the vortex rope shape and

Medical and veterinary medicine staff and specialists represent an important decision making group in national administration and institutions dealing with radiation protection and environmental protection matters in general. Still, their education in physics, especially in radiation physics is fragmentary and loose, both from technical and theoretical point of view. Within medicine and veterinary medicine studies as well as within other biomedical sciences (biology, pharmacology, biotechnology) radiation physics is usually incorporated in the first year curricula as a part of general physics or biophysics course. Some segments of radiation physics mainly as a technical base for different instrumentation methods and techniques could be also found within different graduate and post-graduate courses of radiology, physical therapy, radiation hygiene, environmental protection, etc. But the traditional approach in presenting the matter and inflexibility of the educational system strongly confront the growing public concern for the environmental problems dealing with radiation and demands for better informing and technical education for those involved in informing and administration. This paper considers some of these problems presenting a new approach in education in radiation physics for medical and veterinary medicine students based on education through student projects and work in the field, as well as on the strong collaboration among administration, universities and professional societies on the national and international level.

Goldsmith, Werner; Monson, Kenneth L

2005-01-01

This presentation is the continuation of the article published in Critical Reviews of Biomedical Engineering, 29(5-6), 2001. That issue contained topics dealing with components and geometry of the human head, classification of head injuries, some early experimental studies, and tolerance considerations. It then dealt with head motion and load characterization, investigations during the period from 1939 to 1966, injury causation and early modeling efforts, the 1966 Head Injury Conference and its sequels, mechanical properties of solid tissues, fluid characterization, and early investigation of the mechanical properties of cranial materials. It continued with a description of the systematic investigations of solid cranial components and structural properties since 1966, fetal cranial properties, analytical head modeling, and numerical solutions of head injury. The paper concluded with experimental dynamic loading of human living and cadaver heads, dynamic loading of surrogate heads, and head injury mechanics. This portion of the paper describes physical head injury experimentation involving animals, primarily primates, human cadavers, volunteers, and inanimate physical models. In order to address the entire domain of head injury biomechanics in the two-part survey, it was intended that this information be supplemented by discussions of head injury tolerance and criteria, automotive and sports safety considerations, and the design of protective equipment, but Professor Goldsmith passed away before these sections could be completed. It is nevertheless anticipated that this attenuated installment will provide, in conjunction with the first part of the survey, a valuable resource for students and practitioners of head injury biomechanics.

An ethnobotany of Western Cape Rasta bush medicine.

Aston Philander, Lisa

2011-11-18

This descriptive ethnobiological research is the first documentation of the materials utilized in the pharmacopeia of a novel group of herbalists, Rasta bush doctors, found in the botanically diverse Western Cape of South Africa. This article suggests that medicinal plants used by bush doctors unite the disparate ethnomedicines found in South Africa. Ethnospecies name and parts used were recorded during detailed inventories of 39 bush doctors. Collection of voucher specimens for botanical identification occurred in 15 locations. Herbal remedies were classified into use categories and were compared to historical ethnobotanical literature to ascertain previous cultural affiliations. There were 205 ethnospecies found in the Rastafari ethnobiology, 181 were used medicinally. Ethnospecies belong to 71 plant families and 71% belonged to six plant families: Rutaceae (13), Asteraceae (13), Apiaceae (9), Lamiaceae (8), Fabaceae (8), and Euphorbiaceae (7). The majority of remedies (49%) were foliage. Medicinal plants treated over 30 ailments including: gastrointestinal symptoms (11%), urogential complaints (11%), skin ailments (9%), and cardiovascular diseases (8%). Bush doctors appropriated remedies traditionally important to Zulu, KhoiSan, European and Xhosa healing traditions. Novel plants and plant utilization were noted for 22 plant species. Use of previously undocumented plant materials as medicinals denote distinct local knowledge including novel Rastafarian utilization of herbs for spiritual and ritual purposes. The range of the largely herbaceous pharmacopeia is narrow compared to the region's highly biodiverse materials and historical records of medicinal use. Bush doctors' experimentation with known herbal remedies illustrates a striking level of cross-cultural adaptation. This syncretic pharmacopeia reflects the cultural diversity of Southern Africa, drawing upon recent invasive species, European influence and traditional herbs used by the KhoiSan, Zulu and Xhosa

In the first, historical part the most important programs of "Medical Enlightenment", are pointed out, beginning with Leibniz, followed by the public health movement of the 18th century, up to the time of Immanuel Kant. Based on this historical background several concepts of a "Medical Culture" are analysed in detail, for instance the "Theorie einer Medizinal-Ordnung" by Johann Benjamin Ehrhard (1800), the "Medicinische Reform" by Rudolf Virchow (1848) and the programs of the "Gesellschaft Deutscher Naturforscher und Arzte" (about 1850-1890), the latter bearing both scientific and political character. Following the historical part, the question is raised whether "Enlightenment" is limited by medicine and whether medicine is able to provide a program for individual health education resulting in a more cultivated style of private life, and lastly how this might be realized.

The relevance of the Hippocratic Oath to the ethical and moral values of contemporary medicine. Part I: The Hippocratic Oath from antiquity to modern times.

2017-10-27

The present paper discusses the relevance and significance of the Hippocratic Oath to contemporary medical ethical and moral values. It attempts to answer the questions about some controversial issues related to the Oath. The text is divided in two parts. Part I discusses the general attributes and ethical values of the Oath, while Part II presents a detailed analysis of each passage of the Oath with regard to perennial ethical principles and moral values. Part I starts with the contribution of Hippocrates and his School of Cos to medicine. It continues by examining the moral dilemmas concerning physicians and patients in the Classical Times and in the Modern World. It also investigates how the Hippocratic Oath stands nowadays, with regard to the remarkable and often revolutionary advancements in medical practice and the significant evolution in medical ethics. Further, it presents the debate and the criticism about the relevance of the general attributes and ethical values of the Oath to those of modern societies. Finally, it discusses the endurance of the ethical values of the Hippocratic Oath over the centuries until today with respect to the physicians' commitment to the practice of patient-oriented medicine. Part I concludes with the Oath's historic input in the Judgment delivered at the close of the Nuremberg "Doctors' Trial"; this Judgement has become legally binding for the discipline in the Western World and was the basis of the Nuremberg Code. The ethical code of the Oath turned out to be a fundamental part of western law not only on medical ethics but also on patients' rights regarding research.

Regulatory problems in nuclear medicine

Governmental involvement in the practice of medicine has increased sharply within the past few years. The impact on health care has, for the most part, been in terms of financial interactions between health care facilities and federally funded health services programs. One might say that this type of governmental involvement has indirect impact on the medical and/or technical decisions in the practice of nuclear medicine. In other areas, however, governmental policies and regulations have had a more direct and fundamental impact on nuclear medicine than on any other medical specialty. Without an understanding and acceptance of this situation, the practice of nuclear medicine can be very frustrating. This chapter is thus written in the hope that potential frustration can be reduced or eliminated

Harvard School of Dental Medicine (HSDM) uses a hybrid problem-based approach to teaching in the predoctoral program. The objective structured clinical examination (OSCE) is a formative examination designed to assess the performance of students in the problem-based learning (PBL) curriculum. At HSDM three comprehensive examinations with OSCE components are administered during the third and fourth years of clinical training. The National Board Dental Examination (NBDE) Part II is taken in the final year of the predoctoral program. This study examines the association between the NBDE Part II and the comprehensive exams held at HSDM. Predoctoral students from the HSDM classes of 2005 and 2006 were included in this study. The outcome variable of interest was the scores obtained by students in the NBDE Part II, and the main independent variable of interest was the performance of students in the comprehensive exams (honors, pass, make-up exam to pass). The Mann-Whitney U-test was used to examine the association between the grades obtained in the each of the three comprehensive exams and the NBDE Part II scores. Multivariable linear regression analysis was also used to examine the association between the NBDE Part II scores and the comprehensive exam grades. The effect of potential confounding factors including age, sex, and race/ethnicity was adjusted. The results suggest that students who performed well in the comprehensive exams performed better on the NBDE Part II, even after adjusting for confounding factors. Future studies will examine the long-term impact of PBL on postdoctoral plans and career choices.

Experimental medicine in drug addiction: towards behavioral, cognitive and neurobiological biomarkers.

Science.gov (United States)

Duka, Theodora; Crombag, Hans S; Stephens, David N

2011-09-01

Several theoretical frameworks have been developed to understand putative processes and mechanisms involved in addiction. Whilst these 'theories of addiction' disagree about importance and/or nature of a number of key psychological processes (e.g. the necessity of craving and/or the involvement of drug-value representations), a number of commonalities exist. For instance, it is widely accepted that Pavlovian associations between cues and environmental contexts and the drug effects acquired over the course of addiction play a critical role, especially in relapse vulnerability in detoxified addicts. Additionally, all theories of addiction (explicitly or implicitly) propose that chronic drug exposure produces persistent neuroplastic changes in neurobiological circuitries underlying critical emotional, cognitive and motivational processes, although disagreement exists as to the precise nature of these neurobiological changes and/or their psychological consequences. The present review, rather than limiting itself to any particular theoretical stance, considers various candidate psychological, neurobiological and/or behavioral processes in addiction and outlines conceptual and procedural approaches for the experimental medicine laboratory. The review discusses (1) extinction, renewal and (re)consolidation of learned associations between cues and drugs, (2) the drug reward value, (3) motivational states contributing to drug seeking and (4) reflective (top-down) and sensory (bottom-up) driven decision-making. In evaluating these psychological and/or behavioral processes and their relationship to addiction we make reference to putative underlying brain structures identified by basic animal studies and/or imaging studies with humans.

Molecular nuclear medicine including PET and SPECT is one of the most important parts of the molecular imaging. The combinations of molecular unclear medicine with CT, MRI, ultrasound or optical imaging and synthesis of multimodality radiopharmaceuticals are the major trends of the development of nuclear medicine. Molecular nuclear medicine has more and more and more important value on the monitoring of response to biology involved gene therapy or stem cell therapy and the developments of new drug. (authors)

How philosophy of medicine has changed medical ethics.

Veatch, Robert M

2006-12-01

The celebration of thirty years of publication of The Journal of Medicine and Philosophy provides an opportunity to reflect on how medical ethics has evolved over that period. The reshaping of the field has occurred in no small part because of the impact of branches of philosophy other than ethics. These have included influences from Kantian theory of respect for persons, personal identity theory, philosophy of biology, linguistic analysis of the concepts of health and disease, personhood theory, epistemology, and political philosophy. More critically, medicine itself has begun to be reshaped. The most fundamental restructuring of medicine is currently occurring--stemming, in part, from the application of contemporary philosophy of science to the medical field. There is no journal more central to these critical events of the past three decades than The Journal of Medicine and Philosophy.

The global antimicrobial resistance has been a big challenge to the human health for years. It has to make balance between the safety of animal products and the use of antimicrobials in animal husbandry. Any methods that can minimize or even phase out the use of antimicrobials in animal husbandry should be encouraged. We herein describe the research strategies for feed additives and veterinary medicines from the side products of Chinese medicine resources industrialization. Killing two birds with one stone-besides the major purposes, the rational utilization of non-medicinal parts and wastes of industrialization of Chinese herbal medicines is also achieved under the proposed strategies.

Influence of systemic disorders on periodontal diseases is well established. However, of growing interest is the effect of periodontal diseases on numerous systemic diseases or conditions like cardiovascular disease, cerebrovascular disease, diabetes, pre-term low birth weight babies, preeclampsia, respiratory infections and others including osteoporosis, cancer, rheumatoid arthritis, erectile dysfunction, Alzheimer's disease, gastrointestinal disease, prostatitis, renal diseases, which has also been scientifically validated. This side of the oral-systemic link has been termed Periodontal Medicine and is potentially of great public health significance, as periodontal disease is largely preventable and in many instances readily treatable, hence, providing many new opportunities for preventing and improving prognosis of several systemic pathologic conditions. This review article highlights the importance of prevention and treatment of periodontal diseases as an essential part of preventive medicine to circumvent its deleterious effects on general health.

Gene mutation-based and specific therapies in precision medicine.

Wang, Xiangdong

2016-04-01

Precision medicine has been initiated and gains more and more attention from preclinical and clinical scientists. A number of key elements or critical parts in precision medicine have been described and emphasized to establish a systems understanding of precision medicine. The principle of precision medicine is to treat patients on the basis of genetic alterations after gene mutations are identified, although questions and challenges still remain before clinical application. Therapeutic strategies of precision medicine should be considered according to gene mutation, after biological and functional mechanisms of mutated gene expression or epigenetics, or the correspondent protein, are clearly validated. It is time to explore and develop a strategy to target and correct mutated genes by direct elimination, restoration, correction or repair of mutated sequences/genes. Nevertheless, there are still numerous challenges to integrating widespread genomic testing into individual cancer therapies and into decision making for one or another treatment. There are wide-ranging and complex issues to be solved before precision medicine becomes clinical reality. Thus, the precision medicine can be considered as an extension and part of clinical and translational medicine, a new alternative of clinical therapies and strategies, and have an important impact on disease cures and patient prognoses. © 2015 The Author.

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

Directory of Open Access Journals (Sweden)

Lev Efraim

2006-01-01

Full Text Available Abstract 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!

To examine general practitioners' (GPs') perception of their role in emergency medicine and participation in emergency services including ambulance call outs, and the characteristics of the GPs and casualty clinics associated with the GPs' involvement in emergency medicine. Cross-sectional online survey. General practice. General practitioners in Norway (n = 1002). Proportion of GPs perceiving that they have a large role in emergency medicine, regularly being on call, and the proportion of ambulance callouts with GP participation. Forty six percent of the GPs indicated that they play a large role in emergency medicine, 63 percent of the GPs were regularly on call, and 28 percent responded that they usually took part in ambulance call outs. Multivariable logistic regression analyses indicated that these outcomes were strongly associated with participation in multidisciplinary training. Furthermore, the main outcomes were associated with traits commonly seen at smaller casualty clinics such as those with an absence of nursing personnel and extra physicians, and based on the distance to the hospital. Our findings suggest that GPs play an important role in emergency medicine. Multidisciplinary team training may be important for their continued involvement in prehospital emergencies. Key Points   Health authorities and other stakeholders have raised concerns about general practitioner's (GPs) participation in emergency medicine, but few have studied opinions and perceptions among the GPs themselves.   • Norwegian GPs report playing a large role in emergency medicine, regularly being on call, and taking part in selected ambulance call outs.   • A higher proportion of GPs who took part in team training perceived themselves as playing a large role in emergency medicine, regularly being on call, and taking part in ambulance call outs.   • These outcomes were also associated with attributes commonly seen at smaller casualty clinics.

Herbal medicines (HMs) have been well known to people of the European Union (EU) and Russia for centuries. Currently, Western HMs can be classified into two categories, plant-derived conventional medicines and dietary supplements. Interest to HMs has grown rapidly in all countries during the past two decades. The main goal of this review article is to present the history of HMs in the EU and Russia, forms of modern HMs, including Oriental Medicines that are popular among consumers of both countries. Additional discussion points comprise safety and adulteration issues associated with HMs, including regulatory changes and new legislative measures undertaken by the authorities. Materials available from legislative and governmental websites, PubMed and news media were used. Expert commentary: Due to cultural diversities in the EU and Russia, traditional HMs of other regions, particularly Chinese Traditional and Ayurvedic medicines, are also popular. Recently, dietary supplements containing multiple herbal and other natural products have flooded the EU and Russian markets. Pharmacovigilance in these markets is challenging in terms of establishing quality and safety of ingredients, determining efficacy, and defining risks of herb-herb and herb-drug interactions. Both the EU and Russia have introduced new legislation aimed to overcome these deficiencies.

This paper provides significant ethnobotanical information on medicinal plants in Espiye in the Black Sea Region. Recording such data calls for urgency. This is the first ethnobotanical study in which statistical calculations about plants are carried out by means of FIC method in Northern (Espiye-Giresun) part of Turkey. This study aims to identify the wild plants collected for medicinal purposes by locals of Espiye which is located in the Black Sea Region of Turkey, and to identify the uses and local names of these wild plants. A field study had been carried out for a period of approximately 2 years (2012-2014). During this period, information about medicinal use of 55 wild and 15 cultivated plants were collected. Demographic characteristics of participants, names of the local plants, their utilized parts and preparation methods were investigated and recorded. Through face-to-face interviews, we identified and recorded demographic characteristics of the respondents. We interviewed 128 persons who are over the age of 29. The plant taxa were collected within the scope of the study; and herbarium materials were prepared. In addition, the relative significance value of the taxa was determined, and informant consensus factor (FIC) was calculated for the medicinal plants included in the study. We have found out in the literature review of the plants included in our study that 70 plant taxa are already used for medicinal purposes while 3 plants are not available among the records in the literature. The most common families are Asteraceae, Rosaceae, Lamiaceae, Malvaceae, and Ericaceae. We include in our study and report for the first time the medicinal uses of Alchemilla crinita Buser, Stachys sylvatica L., and Thymus leucotrichus Hal. var. leucotrichus Hal. Names of local plants in Turkey vary especially due to vernaculars. The plants that the locals of Espiye use are called with the same or different local names in various parts of Anatolia. We found out that locals

A rapid, sensitive, and reliable ultra-fast liquid chromatography combined with electrospray ionization tandem mass spectrometry (UFLC-ESI-MS/MS) method was established and applied to simultaneous determination of 31 triazine herbicides and their metabolites in multiple medicinal parts of traditional Chinese medicines (TCMs). A streamlined pretreatment approach using one-step extraction and dilution was proposed, which provided high-throughput processing, excellent recovery, and negligible interference. Afterwards, multiple-reaction monitoring (MRM) and information-dependent acquisition (IDA) triggered enhanced product ion spectra (EPI) was adopted to identify and quantify the targets in a single analysis. The optimized method was then validated according to the guidelines of the European Commission for the following parameters: Matrix effects, specificity, accuracy, precision, linearity, range, and stability. The LOD and LOQ for the 31 triazine herbicides were 0.1-10 μg kg -1 and 0.5-25 μg kg -1 , respectively. Recoveries at three concentration levels were within 67.9-120.3% with an associated precision RSD <20%. Using the proposed approach, trazines herbicides were determined from 44 commercially available TCMs. The detection rate of triazine herbicides residues was 15.9% of the total samples. Among them, atrazine, simeton, and simetryn were found in the radix, herba, and seed TCMs with values far below the referenced maximum residue limits (MRLs), but no residues were detected in either the flos or fructus. Taken together, this method has the potential to provide a means for triazines screening in extensive matrices, thereby laying the foundation for pesticide registration on TCMs. Moreover, it has the potential to guide further triazine residue control in TCMs. Copyright © 2017 Elsevier Ltd.

Evidence-based medicine allows veterinarians to practice high-quality medicine, because the basis for all decision making is quantitative, objective, and reproducible. Case reports and case series are limited in their scope and application. Cross-sectional studies, likewise, cannot provide answers to specific variable testing with a temporal application. It is essential for the reptile specialty to expand into case-control studies, cohort studies, and experimental/intervention studies. Unfortunately, much of the reptile literature remains limited to descriptive studies. This article reviews current evidence-based topics in reptile medicine and shares how everyone practicing in the field can contribute to improving this specialty. Copyright © 2017 Elsevier Inc.

Hatchett, Richard

2017-10-04

The medicines refrigerator is a common piece of equipment found in clinical areas. It is used to ensure specific medicines are safely stored within a narrow temperature range in line with manufacturers' instructions; this is usually between +2˚C and +8˚C, and ideally +5˚C. Drugs stored in the medicines refrigerator include: vaccines; insulin; chemotherapy drugs; topical preparations, such as some types of eye drops; and other treatments such as glucagon, which is used to manage severe hypoglycaemia. This article reviews the function of the medicines refrigerator and the checks required by healthcare practitioners to ensure that medicines remain safely stored and their effectiveness is maintained. It also outlines the medicines refrigeration procedure known as the 'cold chain', which includes the use of cold boxes or vaccine carriers to maintain the required temperature of medicines during transport from the manufacturer to user, or between healthcare departments. ©2012 RCN Publishing Company Ltd.

2002-01-01

Full text: A number of advances in diverse fields of science and technology and the fruitful synchronization of many a new development to address the issues related to health care in terms of prognosis and diagnosis resulted in the availability of host of modern diagnostic tools in medicine. Nuclear medicine, a unique discipline in medicine is one such development, which during the last four decades has seen exponential growth. The unique contribution of this specialty is the ability to examine the dynamic state of every organ of the body with the help of radioactive tracers. This tracer application in nuclear medicine to monitor the biological molecules that participate in the dynamic state of body constituents has led to a whole new approach to biology and medicine. No other technique has the same level of sensitivity and specificity as obtained in radiotracer technique in the study of in-situ chemistry of body organs. As modem medicine becomes oriented towards molecules rather than organs, nuclear medicine will be in the forefront and will become an integral part of a curative process for regular and routine application. Advances in nuclear medicine will proceed along two principal lines: (i) the development of improved sensitive detectors of radiation, powerful and interpretable data processing, image analysis and display techniques, and (ii) the production of exotic and new but useful radiopharmaceuticals. All these aspects are dealt with in detail in this talk

The growing popularity of complementary and alternative medicine (CAM), of which estimated 38% of adults in the United States used in 2007, has engendered changes in medical school curricula to increase students' awareness of it. Exchange programs between conventional medical schools and CAM institutions are recognized as an effective method of interprofessional education. The exchange program between Albert Einstein College of Medicine (Einstein, Yeshiva University) and Pacific College of Oriental Medicine, New York campus (PCOM-NY) is in its fifth year and is part of a broader relationship between the schools encompassing research, clinical training, interinstitutional faculty and board appointments, and several educational activities. The Einstein/PCOM-NY student education exchange program is part of the Einstein Introduction to Clinical Medicine Program and involves students from Einstein learning about Chinese medicine through a lecture, the experience of having acupuncture, and a four-hour preceptorship at the PCOM outpatient clinic. The students from PCOM learn about allopathic medicine training through an orientation lecture, a two-and-a-half-hour dissection laboratory session along side Einstein student hosts, and a tour of the clinical skills center at the Einstein campus. In the 2011/2012 offering of the exchange program, the participating Einstein and PCOM students were surveyed to assess the educational outcomes. The data indicate that the exchange program was highly valued by all students and provided a unique learning experience. Survey responses from the Einstein students indicated the need for greater emphasis on referral information, which has been highlighted in the literature as an important medical curriculum integrative medicine competency.

Between the Living and the Dead: Trauma Medicine and Forensic Medicine in the Mid-Qing.

Science.gov (United States)

Wu, Yi-Li

2015-03-01

This paper analyzes the influence of forensic medicine on therapeutic medicine through a case study of Qian Xiuchang and Hu Tingguang, two Chinese doctors who specialized in treating traumatic injuries. During the early nineteenth century, both men compiled medical treatises that sought to improve on a scholarly model of "rectifying bones" articulated in 1742 by the Imperially-Compiled Golden Mirror of the Medical Lineage . Both texts also incorporated information from forensic medicine, including official inquest diagrams and checklists promulgated by the Qing government. I show that they drew on these forensic materials to help address two interlinked medical issues: understanding the effects of injury on different parts of the body, and clarifying the location and form of the body's bones. Overall, I suggest that the exchange of ideas between the realm of therapeutic medicine and forensic medicine was an important epistemological strategy that doctors and officials alike employed to improve their knowledge of the material body.

[The methods of Western medicine in on ancient medicine].

Science.gov (United States)

Ban, Deokjin

2010-06-30

The treatise On Ancient Medicine attests that questions of method were being debated both in medicine and in philosophy and is important evidence of cross-discipline methodological controversy. The treatise On Ancient Medicine is the first attempt in the history of Greek thought to provide a detailed account of the development of a science from a starting point in observation and experience. The author of it criticizes philosophical physicians who attempt to systematized medicine by reducing it to the interaction of one or more of the opposites hot, cold, wet, and dry, factors. He regards the theory of his opponents as hypothesis(hypothesis). Medicine has long been in possession of both an archē and a hodos, a principle and a method, which have enabled it to make discoveries over a long period of time. As far as method is concerned, the traditional science of medicine attained the knowledge of the visible by starting from observation and experience, but it recommended the use of reasoning and analogies with familiar objects as a means of learning about the invisible. It also utilized inference from the visible to the visible(epilogismos) and inference from the visible to the invisible(analogismos). The use of analogy as a means of learning about the obscure was also part of the common heritage of early philosophy and medicine. But the author's use of the analogical method distinguishes it from Empedocles' well-known analogy comparisons of the eye to a lantern and the process of respiration to the operations of a clepsydra. According to the author, traditional science of medicine used functional analogy like wine example and cheese example to know the function of humors within the body and utilized structured analogy like a tube example and a cupping instrument example to acknowledge an organ or structure within the body. But the author didn't distinguish between the claim that medicine has a systematic method of making discoveries and very different claim that it

Experimental Program: assembly of an experiment as Fermilab E-531 to measure decay lifetimes, with tagged emulsion of charmed particles produced by high energy neutrinos was finished, and data taking now is in progress. An experiment to measure prompt neutrino production at Fermilab, E-613, was approved and detailed design of it is continuing. Search for parity violation in scattering of polarized protons, an experiment E-446-ZGS at ANL, was performed with the sensitivity of 10 -6 for detection of that process and yielded null results. Another run with improved sensitivity of 10 -7 is in preparation. Data analysis of the neutrino experiment E-310 at Fermilab will continue. Trimuon events, a new discovery, were identified in those data. Analysis of data on meson production from experiments performed at the ZGS--ANL, E-397, E-420 and E-428, with charged and neutral spectrometer will continue. A new relatively broad resonance (T approx. 70 MeV) with quantum numbers IJ/sup P/ = 00 -1 was discovered in the data from E-397. Analysis of beta decay of polarized Σ - hyperons is in progress. Participation in the design of the experimental areas for the Isabelle colliding proton beam accelerator will continue. Theoretical Program: topics of current interest in particle theory which will be investigated in the coming year are: the instanton-anti-instanton QCD gauge fields, discrete symmetries which may determine quark masses in the SU(2) x U(1) model, calculation of charmed meson production in e + e - collisions and formation of gluon jets, Higgs boson production in pp collisions, calculation of Higgs boson mass in terms of vector boson mass, study of Lagrangians with gauge and Higgs scalar fields, investigation of Faddeev--Popov determinants as related to quantum chromodynamics, a study of quantum flavor dynamics and anomalies in the axial vector Ward identity and a study of super symmetry as a part of a realistic model of leptonic interactions

Thermoluminescence dosimetry and its applications in medicine. Part 2: history and applications

International Nuclear Information System (INIS)

Kron, T.

1995-01-01

Thermoluminescence dosimetry (TLD) has been available for dosimetry of ionising radiation for nearly 100 years. The variety of materials and their different physical forms allow the determination of different radiation qualities over a wide range of absorbed dose. This makes TL dosimeters useful in radiation protection where dose levels of μ Gy are monitored as well as in radiotherapy where doses up to several Gray are to be measured. The major advantages of TL detectors are their small physical size and that no cables or auxiliary equipment is required during the dose assessment. TLD is considered to be a good method for point dose measurements in phantoms as well as for in vivo dosimetry on patients during radiotherapy treatment. As an integrative dosimetric technique, it can be applied to personal dosimetry and it lends itself to the determination of dose distributions due to multiple or moving radiation sources (e.g. conformal and dynamic radiotherapy, computed tomography). In addition, TL dosimeters are easy to transport, and they can be mailed. This makes them well suited for intercomparison of doses delivered in different institutions. The present article aims at describing the various applications TLD has found in medicine by taking into consideration the physics and practice of TLD measurements which have been discussed in the first part of this review. 198 refs., 4 tabs., 2 figs

Cavagnini, Gianluca; Sansoni, Giovanna; Trebeschi, Marco

2009-01-01

Crime scene documentation and legal medicine analysis are part of a very complex process which is aimed at identifying the offender starting from the collection of the evidences on the scene. This part of the investigation is very critical, since the crime scene is extremely volatile, and once it is removed, it can not be precisely created again. For this reason, the documentation process should be as complete as possible, with minimum invasiveness. The use of optical 3D imaging sensors has been considered as a possible aid to perform the documentation step, since (i) the measurement is contactless and (ii) the process required to editing and modeling the 3D data is quite similar to the reverse engineering procedures originally developed for the manufacturing field. In this paper we show the most important results obtained in the experimentation.

What is precision medicine?

König, Inke R; Fuchs, Oliver; Hansen, Gesine; von Mutius, Erika; Kopp, Matthias V

2017-10-01

The term "precision medicine" has become very popular over recent years, fuelled by scientific as well as political perspectives. Despite its popularity, its exact meaning, and how it is different from other popular terms such as "stratified medicine", "targeted therapy" or "deep phenotyping" remains unclear. Commonly applied definitions focus on the stratification of patients, sometimes referred to as a novel taxonomy, and this is derived using large-scale data including clinical, lifestyle, genetic and further biomarker information, thus going beyond the classical "signs-and-symptoms" approach.While these aspects are relevant, this description leaves open a number of questions. For example, when does precision medicine begin? In which way does the stratification of patients translate into better healthcare? And can precision medicine be viewed as the end-point of a novel stratification of patients, as implied, or is it rather a greater whole?To clarify this, the aim of this paper is to provide a more comprehensive definition that focuses on precision medicine as a process. It will be shown that this proposed framework incorporates the derivation of novel taxonomies and their role in healthcare as part of the cycle, but also covers related terms. Copyright ©ERS 2017.

Full Text Available Mainstreaming traditional systems of medicine and integrating them with the established health delivery mechanisms is an important step in accelerating advancement of health sciences to achieve current global health care goals. This paper proposes the "axial-model" of Integrative Medicine (IM. A replicable model, viable across multiple IM possibilities, which are clinically beneficial, supports evidence-based evolution and is socially acceptable. Axial model may be implemented to integrate two or more systems of medicines, provided they are legally regulated and approved for clinical administration. It proposes three consecutively phased clinical processes, named parallel, complementary and protocol, respectively. The model supports translational medicine by mainstreaming beneficial practices of traditional medicine as a part of its process of execution.

The operating conditions of the up-draught part of a large diameter and limited height is characterized by hydrodynamic non-uniformity of distribution of steam content field over its volume. In the up-draught part of the reactor owing to its limited height hydrodynamic flow stabilization over the section is not attained. The higher void fraction in the central region of the up-draught part (owing to higher energy release in the centre of the core) causes accelerated coolant motion upwatds which results in steam migration from the periphery to the centre and to increase of general non-uniformity of steam distribution. The revealed steam distribution non-uniformity over the height and radius of the up-draught part elucidates the discrepancy of experimental and calculation values of the average volumetric steam content and determines the necessity of the development of new calculation methods

Systems medicine promotes a range of approaches and strategies to study human health and disease at a systems level with the aim of improving the overall well-being of (healthy) individuals, and preventing, diagnosing, or curing disease. In this chapter we discuss how bioinformatics critically contributes to systems medicine. First, we explain the role of bioinformatics in the management and analysis of data. In particular we show the importance of publicly available biological and clinical repositories to support systems medicine studies. Second, we discuss how the integration and analysis of multiple types of omics data through integrative bioinformatics may facilitate the determination of more predictive and robust disease signatures, lead to a better understanding of (patho)physiological molecular mechanisms, and facilitate personalized medicine. Third, we focus on network analysis and discuss how gene networks can be constructed from omics data and how these networks can be decomposed into smaller modules. We discuss how the resulting modules can be used to generate experimentally testable hypotheses, provide insight into disease mechanisms, and lead to predictive models. Throughout, we provide several examples demonstrating how bioinformatics contributes to systems medicine and discuss future challenges in bioinformatics that need to be addressed to enable the advancement of systems medicine.

Medicine and ionizing rays: a help sheet in analysing risks in nuclear medicine

International Nuclear Information System (INIS)

Gauron, C.

2006-01-01

This document first proposes the various applicable legal and regulatory texts concerning radioprotection in the medical sector (European directives, institutions in charge of radioprotection, general arrangements, regulatory texts concerning worker protection against ionizing radiations, personnel specialized in medical radio-physics, electro-radiology operators, quality control of medical devices, and nuclear medicine and radiology). The second part proposes a synthesis of useful knowledge for radioprotection in the case of nuclear medicine when performing in vivo diagnosis, positron emission tomography or PET being excluded. Several aspects are considered: the concerned personnel, the course of treatment procedures, the hazards, the identification of the risk associated with ionizing radiation, the risk assessment and the determination of exposure levels, the strategy to control the risks (reduction of risks, technical measures concerning the installation or the personnel, teaching and information, prevention and medical monitoring), and risk control assessment. The next parts present the same kind of information but for positron emission tomography or PET with Fluorine 18, for therapeutic practice without hospitalization (activity of iodine 137 less than 740 MBq), for therapeutic practice in case of hospitalization (iodine 137 activity greater than 740 MBq), and when taking patients into care after treatment in a nuclear medicine (in this last case, legal and regulatory information focus on patients)

Rational use of medicines - Indian perspective!

Science.gov (United States)

Mohanta, G P; Manna, P K

2015-01-01

India, the largest democracy in the world, is with a federal structure of 29 states and 7 union territories. With a population of more than 1.2 billion, resource is always a constraint and so is in the health system too. In the federal structure, providing healthcare is largely the responsibility of state governments. Medicines are important component of health care delivery system and quality care is dependent on the availability and proper use of quality medicines. In spite of being known as pharmacy of the third world, poor access to medicines in the country is always a serious concern. Realizing the need of quality use of medicines, several initiatives have been initiated. As early as 1994, seeds of rational use of medicines were sown in the country with two initiatives: establishment of a civil society, Delhi Society for Promoting Rational Use of Drugs (DSPURD) and establishment of government agency in Tamil Nadu, a southern state, called Tamil Medical Services Corporation Limited (TNMSCL). DSPUD was in official association with World Health Organization Country Office for implementing essential medicine programme in the country for two biennia. In addition to organizing sensitising and training programme for healthcare professionals throughout the country, it looked after the procurement and appropriate use of medicines in Delhi government health facilities. TNMSCL has made innovations in medicine management including procurement directly from manufacturers as a part of pooled procurement, establishing warehouses with modern storage facilities and Information Technology enabled management of whole process. TNMSCL Model is now replicated in almost the entire country and even in some small other countries as it is successful in improving access to medicines.The National Government and the State Governments have developed strategies to promote rational use of medicines as a part of improving access and quality care in public health facilities.

Full Text Available Abstract Background Thousands of plants and animals possess pharmacological properties and there is an increased interest in using these materials for therapy and health maintenance. Efficacies of the application is critically dependent on the use of genuine materials. For time to time, life-threatening poisoning is found because toxic adulterant or substitute is administered. DNA barcoding provides a definitive means of authentication and for conducting molecular systematics studies. Owing to the reduced cost in DNA authentication, the volume of the DNA barcodes produced for medicinal materials is on the rise and necessitates the development of an integrated DNA database. Description We have developed an integrated DNA barcode multimedia information platform- Medicinal Materials DNA Barcode Database (MMDBD for data retrieval and similarity search. MMDBD contains over 1000 species of medicinal materials listed in the Chinese Pharmacopoeia and American Herbal Pharmacopoeia. MMDBD also contains useful information of the medicinal material, including resources, adulterant information, medical parts, photographs, primers used for obtaining the barcodes and key references. MMDBD can be accessed at http://www.cuhk.edu.hk/icm/mmdbd.htm.

Hostenkamp, Gisela

2012-01-01

Pharmaceutical expenditure growth has outpaced GDP and healthcare expenditure growth rates in Denmark as in most OECD countries for the last decade. A major part of this increase was due to high growth rates in specialist areas that are typically located in hospital settings. Yet the market...... for hospital medicines and their procurement are still poorly understood. The present paper characterises the market for hospital medicines in Denmark in terms of its organisation and developments between 2005 and 2009. In Denmark hospital medicines are publicly financed and procurement is centrally organised....... 98% of all medicines administered at Danish public hospitals are purchased through a public procurement agency by means of public tenders. Using data on actual contract prices we decompose pharmaceutical expenditure growth into the contributions from newly introduced medicines, price and volume...

Several parts of plants are used in herbal and Ayurvedic medicines of India. The different elemental constituents at trace levels of these plant parts play an effective role in the medicines prepared. Elemental composition of different parts (root, bark, leaf, seed) of some medicinal plants of North Eastern India has been determined by using proton induced X-ray emission (PIXE). A total of 14 elements, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Br, Rb, Sr, Y, Zr and Pb have been measured. Their concentrations were found to vary in different samples. Medicinal properties of these plant samples and their elemental distribution have been correlated. (author)

Applications of radioisotopes in medicine

International Nuclear Information System (INIS)

Sivaprasad, N.

2012-01-01

The application of radioisotopes in medicine is many folds. They can be classified into two main groups. (a) The radioisotope tagged labeled compounds suitable for safe administration in the body for diagnosis of various diseases of vital organs such as brain, kidney, thyroid etc and for treatment known as radiotherapy (b) The sealed source of radioisotopes for utilizing the radiation emitted from the radioisotope for treatment, particularly for radiation therapy of cancer. The former application of radioisotope in the field of medicine has led to the formation of special branch of medicine termed Nuclear Medicine - the branch of medicine deals with the use of radioisotope in the from of radiopharmaceuticals for investigation, diagnosis and treatment of diseases. Radioisotopes in the form of radiolabelled compound and bio-chemicals that are pharmaceutically and radiologically safe for administration in the body for diagnosis and treatment are called radiopharmaceuticals. The radiopharmaceuticals are the results of world-wide effort to bring nuclear energy in a tangible form for diagnosis and treatment. Radioisotopes as radiopharmaceuticals thus constitute one of the key requirements for nuclear medicine investigation and radiotherapy. In the case of sealed radioisotope source the radiation emitted by the radioactive source is utilized for the treatment and this mode of treatment is called radiation therapy where no radioactive substance is administrated into the body. This does not form the part of nuclear medicine

Epidemiology in wonderland: Big Data and precision medicine.

Science.gov (United States)

Saracci, Rodolfo

2018-03-01

Big Data and precision medicine, two major contemporary challenges for epidemiology, are critically examined from two different angles. In Part 1 Big Data collected for research purposes (Big research Data) and Big Data used for research although collected for other primary purposes (Big secondary Data) are discussed in the light of the fundamental common requirement of data validity, prevailing over "bigness". Precision medicine is treated developing the key point that high relative risks are as a rule required to make a variable or combination of variables suitable for prediction of disease occurrence, outcome or response to treatment; the commercial proliferation of allegedly predictive tests of unknown or poor validity is commented. Part 2 proposes a "wise epidemiology" approach to: (a) choosing in a context imprinted by Big Data and precision medicine-epidemiological research projects actually relevant to population health, (b) training epidemiologists, (c) investigating the impact on clinical practices and doctor-patient relation of the influx of Big Data and computerized medicine and (d) clarifying whether today "health" may be redefined-as some maintain in purely technological terms.

Experimental data obtained in this study (Part II) complement the speciation data presented in Part I, but also offer a basis for extensive facility cross-comparisons for both experimental ignition delay time (IDT) and laminar flame speed (LFS) observables. To improve our understanding of the ignition characteristics of propene, a series of IDT experiments were performed in six different shock tubes and two rapid compression machines (RCMs) under conditions not previously studied. This work is the first of its kind to directly compare ignition in several different shock tubes over a wide range of conditions. For common nominal reaction conditions among these facilities, cross-comparison of shock tube IDTs suggests 20-30% reproducibility (2σ) for the IDT observable. The combination of shock tube and RCM data greatly expands the data available for validation of propene oxidation models to higher pressures (2-40. atm) and lower temperatures (750-1750. K).Propene flames were studied at pressures from 1 to 20. atm and unburned gas temperatures of 295-398. K for a range of equivalence ratios and dilutions in different facilities. The present propene-air LFS results at 1. atm were also compared to LFS measurements from the literature. With respect to initial reaction conditions, the present experimental LFS cross-comparison is not as comprehensive as the IDT comparison; however, it still suggests reproducibility limits for the LFS observable. For the LFS results, there was agreement between certain data sets and for certain equivalence ratios (mostly in the lean region), but the remaining discrepancies highlight the need to reduce uncertainties in laminar flame speed experiments amongst different groups and different methods. Moreover, this is the first study to investigate the burning rate characteristics of propene at elevated pressures (>5. atm).IDT and LFS measurements are compared to predictions of the chemical kinetic mechanism presented in Part I and good

A few factors such as age, stress, and emotions may lead to impaired learning, memory loss, amnesia, and dementia or threats like schizophrenia and Alzheimer's disease (AD). Iranian traditional medicine (ITM) recommends some herbs and herbal preparations for the treatment or prevention of CNS problems. In this study, scientific evidence related to the effectiveness of ITM herbal medicine on memory, learning and AD is reviewed. The scientific evidence of plant efficacy was searched in electronic databases including PubMed, Scopus, SID, Science Direct, and Google Scholar by keywords such as memory, Alzheimer, amnesia, learning and scientific plant names from 1969 to 2014. The findings of this study confirmed the effectiveness of certain ITM medicinal plants on enhancing memory and learning or in the treatment/prevention of amnesia and AD. Some ITM plants like Melissa officinalis, Crocus sativus and Nigella sativa showed improving effects on memory and the treatment of AD in clinical trials. In some cases, active principles responsible for the efficacy of these plants on memory were also determined. Most of the studies on ITM plants were designed in animal models and a few herbs were evaluated in clinical trials on AD. Furthermore, there are insufficient or no investigations on certain herbal medicines used in ITM to confirm their effectiveness on memory and learning. Therefore, further experimental and clinical studies are necessary to evaluate the effectiveness of these plants on memory and AD as well as determining their active components.

The incidence of cardiovascular diseases (CVDs) is very high in human societies and their prevention and treatment are the most important priority in many countries. Hypertension makes an important contribution to the development of CVDs. This study aimed to collect the ethno-medicinal knowledge of the traditional healers of Shiraz on medicinal plants used in the treatment of hypertension. Ethno-medicinal data were collected from September 2012 to July 2013 through direct interview. Twenty-five healers were interviewed using semi-structured questionnaires and their traditional ethno-medicinal knowledge was recorded. Questionnaires were included apothecary personal information, plant local name, plant parts used, method of preparation, season of harvest and traditional use. Data collected from surveys and interviews were transferred to Microsoft Excel 2007 and analyzed. Analysis of data showed that, 27 medicinal plants from 22 families are used for the treatment of hypertension. The families with most antihypertensive species were Apiaceae (8%), Rosaceae (8%) and Papaveraceae (8%). The most frequently used plant parts were leaves (36%) followed by fruits (30%), aerial part (17%) and branches (7%). The most frequently used preparation method was decoction (95%). Borago officinalis (51.85%), Berberis vulgaris (51.58%) had the highest frequency of mention. The ethno-medicinal survey of medicinal plants recommended by traditional healers for the treatment of hypertension provides new areas of research on the antihypertensive effect of medicinal plants. In the case of safety and effectiveness, they can be refined and processed to produce natural drugs.

Nuclear power in human medicine

International Nuclear Information System (INIS)

Kuczera, Bernhard

2012-01-01

The public widely associate nuclear power with the megawatt dimensions of nuclear power plants in which nuclear power is released and used for electricity production. While this use of nuclear power for electricity generation is rejected by part of the population adopting the polemic attitude of ''opting out of nuclear,'' the application of nuclear power in medicine is generally accepted. The appreciative, positive term used in this case is nuclear medicine. Both areas, nuclear medicine and environmentally friendly nuclear electricity production, can be traced back to one common origin, i.e. the ''Atoms for Peace'' speech by U.S. President Eisenhower to the U.N. Plenary Assembly on December 8, 1953. The methods of examination and treatment in nuclear medicine are illustrated in a few examples from the perspective of a nuclear engineer. Nuclear medicine is a medical discipline dealing with the use of radionuclides in humans for medical purposes. This is based on 2 principles, namely that the human organism is unable to distinguish among different isotopes in metabolic processes, and the radioactive substances are employed in amounts so small that metabolic processes will not be influenced. As in classical medicine, the application of these principles serves two complementary purposes: diagnosis and therapy. (orig.)

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

From Desire to Data: How JLab's Experimental Program Evolved Part 2: The Painstaking Transition to Concrete Plans, Mid-1980s to 1990

This is the second in a three-part article describing the development of the Thomas Jefferson National Accelerator Facility's experimental program, from the first dreams of incisive electromagnetic probes into the structure of the nucleus through the era in which equipment was designed and constructed and a program crafted so that the long-desired experiments could begin. These developments unfolded against the backdrop of the rise of the more bureaucratic New Big Science and the intellectual tumult that grew from increasing understanding and interest in quark-level physics. Part 2, presented here, focuses on the period from 1986 to 1990. During this period of revolutionary change, laboratory personnel, potential users, and DOE officials labored to proceed from the 1986 laboratory design report, which included detailed accelerator plans and very preliminary experimental equipment sketches, to an approved 1990 experimental equipment conceptual design report, which provided designs complete enough for the onset of experimental equipment construction.

The state of the art in nuclear medicine

International Nuclear Information System (INIS)

Scott, A.M.

1999-01-01

Recent improvements in the understanding of the physiologic and biologic mechanisms of health and disease have led to an expansion of nuclear medicine applications both in clinical studies and research. Advances in radiopharmaceutical development, instrumentation and computer processing have resulted in the implementation of Positron Emission Tomography for clinical studies, and improved treatments with radiopharmaceuticals particularly in cancer patients. There has also been a dramatic increase in the techniques available with nuclear medicine to detect and measure cellular biologic events in-vivo, which have important implications in clinical and basic science research. Nuclear medicine studies provide unique information on human physiology and remain an integral part of clinical medicine practice

Precision medicine: what's all the fuss about?

Barker, Richard

2016-01-01

Precision medicine is now recognized globally as a major new era in medicine. It is being driven by advances in genomics and other 'omics' but also by the desire on the part of both health systems and governments to offer more targeted and cost-effective care. However, it faces a number of challenges, from the economics of developing more expensive companion diagnostics to the need to educate patients and the public on the advantages for them. New models of both R&D and care delivery are needed to capture the scientific, clinical and economic benefits of precision medicine.

Infertility is one of the most important reproductive health concerns in the conventional medicine. Iranian traditional medicine presents different viewpoints in this regard which they could be of benefit and a good guide for the society of medicine. This study sought to provide the comprehensive investigation on the causes of infertility according to Iranian traditional medicine for understanding of old sages' ideas and categorizing of the causes of infertility. In this narrative review, we searched causes of infertility in traditional medicine books and available articles in this field. Iranian traditional physicians have investigated the causes of infertility in couples and attributed them to male and female causes. They have divided the main causes of infertility in both sexes into structural and functional abnormalities, that both traditional medicine and conventional medicine have a lot of participations, but the traditional medicine believes holistic approach in the treatment of diseases and the involvement of all parts of the body particularly specialty board members (heart, liver, brain, ovary, and testicles) in the proper conduct activities in different parts of the body such as reproduction system. There is also special attention to temperament Mizaj disorders. Given the numerous commonalities existing between traditional and conventional medicine in categorizing the causes of infertility, Iranian traditional medicine methods can be applied as a complementary solution in infertility. It could be also subject to further research and investigation due to its opposition to modern medicine in some regards. PMID:28835934

The crisis of the western system of medicine in contemporary capitalism.

Science.gov (United States)

Navarro, V

1978-01-01

This article makes a critique of current interpretations of the crises of the western system of medicine and presents alternative explanations for those crises. It indicates that the crises of medicine--reflected in its ubiquitous problems of costs and ineffectiveness--are due to and reflect the crises of legitimation and capital accumulation of contemporary capitalism. The article is divided into six parts: the first two define the characteristics of the crises of western contemporary capitalism and of its system of medicine, with a critique of current theories which try to explain them. Parts three and four contrapose to these theories a Marxist interpretation of the crises, tracing their causes to the needs created by the process of capital accumulation and to the demands expressed by the working population. The needs and demands generated by Capital and Labor are intrinsically in conflict, and are realized in the daily practice of class struggle. The characteristics and consequences of that struggle for health and for the organization, content, and ideology of medicine are analyzed in the fifth part. This class struggle takes place within a political context in which Capital and its social expression, the bouregeoisie or corporate class, have the dominant influence on the organs of the State. The sixth part of the article shows how that dominance determines the nature of the State responses to the crises of medicine. A primary thesis of this paper is that social class, class struggle, capitalism, and imperialism are not passé categories, as most ideologists of capitalism postulate, but rather they are the most important paradigms for understanding the crises of the western system of power and its medicine.

Making medicine; producing pleasure: A critical examination of medicinal cannabis policy and law in Victoria, Australia.

Science.gov (United States)

Lancaster, Kari; Seear, Kate; Ritter, Alison

2017-11-01

Several jurisdictions around the world have introduced policies and laws allowing for the legal use of cannabis for therapeutic purposes. However, there has been little critical discussion of how the object of 'medicinal cannabis' is enacted in policy and practice. Informed by Carol Bacchi's poststructuralist approach to policy analysis and the work of science and technology studies scholars, this paper seeks to problematise the object of 'medicinal cannabis' and examine how it is constituted through governing practices. In particular, we consider how the making of the object of 'medicinal cannabis' might constrain or enact discourses of pleasure. As a case example, we take the Victorian Law Reform Commission's review of law reform options to allow people in the Australian state of Victoria to be treated with medicinal cannabis. Through analysis of this case example, we find that although 'medicinal cannabis' is constituted as a thoroughly medical object, it is also constituted as unique. We argue that medicinal cannabis is enacted in part through the production of another object (so-called 'recreational cannabis') and the social and political meanings attached to both. Although both 'substances' are constituted as distinct, 'medicinal cannabis' relies on the 'absent presence' of 'recreational cannabis' to define and shape what it is. However, we find that contained within this rendering of 'medicinal cannabis' are complex enactments of health and wellbeing, which open up discourses of pleasure. 'Medicinal cannabis' appears to challenge the idea that the effects of 'medicine' cannot be understood in terms of pleasure. As such, the making of 'medicinal cannabis' as a medical object, and its invocation of broad notions of health and wellbeing, expand the ways in which drug effects can be acknowledged, including pleasurable and desirable effects, helping us to think differently about both medicine and other forms of drug use.

2015-05-26

This paper provides significant ethnobotanical information on medicinal plants in the villages of Çatak in the Eastern Anatolia Region. Recording such data calls for urgency. This is the first ethnobotanical study in which statistical calculations about plants are carried out by means of FIC method in Eastern (Van) part of Turkey. This study aims to identify the wild plants collected for medicinal purposes by locals of Çatak which is located in the Eastern Anatolia Region of Turkey, and to identify the uses and local names of these wild plants. A field study had been carried out for a period of approximately 2 years (2010-2012). During this period, 78 plants taxa were collected. Demographic characteristics of participants, names of the local plants, their utilized parts and preparation methods were investigated and recorded. The plant taxa were collected within the scope of the study; and herbarium materials were prepared. In addition, the relative significance value of the taxa was determined, and informant consensus factor (FIC) was calculated for the medicinal plants included in the study. We have found out in the literature review of the plants included in our study that 78 plant taxa are already used for medicinal purposes while 19 plants are not available among the records in the literature. The most common families are Asteraceae, Apiaceae, Lamiaceae, Rosaceae, Euphorbiaceae, Fabaceae, and Malvaceae. We include in our study and report for the first time the medicinal uses of Alchemilla buseriana Rothm., Astragalus longifolius Lam., Cephalaria microcephala Boiss., Euphorbia grisophylla M.S. Khan, Fritillaria crassifolia Boiss. & Huet. subsp. kurdica (Boiss. & Noe) Rix, Fritillaria pinardii Boiss., Malabaila lasiocarpa Boiss., Nepeta betonicifolia C.A.

Hospital Medicine (Part 1): what is wrong with acute hospital care?

LENUS (Irish Health Repository)

Kellett, John

2009-09-01

Modern hospitals are facing several challenges and, over the last decade in particular, many of these institutions have become dysfunctional. Paradoxically as medicine has become more successful the demand for acute hospital care has increased, yet there is no consensus on what conditions or complaints require hospital admission and there is wide variation in the mortality rates, length of stay and possibly standards of care between different units. Most acutely ill patients are elderly and instead of one straightforward diagnosis are more likely to have a complex combination of multiple co-morbid conditions. Any elderly patient admitted to hospital is at considerable risk which must be balanced against the possible benefits. Although most of the patients in hospital die from only approximately ten diagnoses, obvious life saving treatment is often delayed by a junior doctor in-training first performing an exhaustive complete history and physical, and then ordering a number of investigations before consulting a senior colleague. Following this traditional hierarchy delays care with several "futile cycles" of clinical activity thoughtlessly directed at the patient without any benefit being delivered. If acute hospital medicine is to be improved changes in traditional assumptions, attitudes, beliefs and practices are needed.

Personalised Medicine and the Economy of Biotechnological Promise.

Science.gov (United States)

Sturdy, Steve

2017-04-01

Rather than seek to distinguish hype from legitimate promise, it may be more helpful to think about personalised medicine as embodying a promissory economy which serves both to mobilize resources for research and - partly at least - to determine the ends to which that research is directed. Personalised medicine is a development of the larger promissory economy of medical biotechnology. As such, it systematically conflates public benefit with the pursuit of commercial and especially pharmaceutical interests. Consequently, research and development in personalised medicine tends to favour the production of expensive new treatments over unprofitable forms of prevention or more effective use of older therapies. A rebalancing of research priorities is needed to favour the pursuit of public benefit, even when it does not deliver private profits. This will in turn require sustained reflection, self-criticism and often self-denial on the part of public research funders and the scientists they support.

A Review of Herbal Remedies for Multiple Sclerosis-Like Disorders in Traditional Persian Medicine (TPM).

Zarshenas, Mohammad M; Ansari, Ramin; Dadbakhsh, Amirhossein; Mohammadi, Maryam

2018-01-01

Among various neurological disorders, multiple sclerosis (MS) is an expanding global immune- related inflammatory disease with complex etiologies. There is increasing demand for the use and administration of natural medicaments for this disorder. Traditional Persian Medicine (TPM) is a school of medicine and a medicinal plants-based resource for clinical studies put forward by Persian scholars. This paper aims to gather and study the effectiveness of all medicinal plants from the most popular Persian pharmacopeias. Five main Persian pharmacopeias from the 9th to the 18th century A.D. have been studied to identify the remedial plants for this disorder. Moreover, PubMed, and Scopus databases have been checked to derive relevant activities for these plants. Khaddar (numbness), Esterkha (Palsy) and Falej (quadriplegia) are traditional definitions; these are clinically close to what is known as MS in today's medicine. In all, 118 medicinal plants, related to 65 families, have been authenticated out of 157 chosen medicaments. Apiaceae is the most frequent family (13 reports). Fruits and roots of plants have been the most reported botanical parts (34 and 32 items). The employed routes of administration are topical, oral, or a combination of the two (27, 57, and 34 sequentially). Fifteen medicines have been reported for Khaddar, Esterkha, and Falej simultaneously. Antioxidant activities, immunomodulatory, and anti-inflammatory properties of medicines are known as some main mechanisms to manage MS. These functions are possessed by 81%, 36%, and 48% of the studied plants, respectively. Hence, conducting adducible clinical trials and highly approved experimental tests on animals may lead to novel drugs with lesser undesirable and much more therapeutic effects on controlling MS.

[Complementary and alternative medicine in oncology].

Science.gov (United States)

Hübner, J

2013-06-01

Complementary and alternative medicine are frequently used by cancer patients. The main benefit of complementary medicine is that it gives patients the chance to become active. Complementary therapy can reduce the side effects of conventional therapy. However, we have to give due consideration to side effects and interactions: the latter being able to reduce the effectiveness of cancer therapy and so to jeopardise the success of therapy. Therefore, complementary therapy should be managed by the oncologist. It is based on a common concept of cancerogenesis with conventional therapy. Complement therapy can be assessed in studies. Alternative medicine in contrast rejects common rules of evidence-based medicine. It starts from its own concepts of cancerogenesis, which is often in line with the thinking of lay persons. Alternative medicine is offered as either "alternative" to recommended cancer treatment or is used at the same time but without due regard for the interactions. Alternative medicine is a high risk to patients. In the following two parts of the article, the most important complementary and alternative therapies cancer patients use nowadays are presented and assessed according to published evidence.

Marketing Approval of Ethical Kampo Medicines.

Science.gov (United States)

Hakamatsuka, Takashi

2017-01-01

Kampo medicine is an original traditional medicine in Japan. Currently, 148 ethical Kampo formulations (Kampo prescription drugs) are registered in the National Health Insurance Price List. Kampo medicines can be prescribed under the national insurance system, which shows that they are part of conventional medicine in Japan. Japan has a unified drug approval system that does not distinguish between Western and Kampo medicines, and both are subject to the same regulations. The application for the market approval of ethical Kampo medicines is based on the general notification for drugs, i.e., "Handling of Ethical Combination Drugs" in "Precautions Necessary When Applying for Drug Marketing Approval" (Yakushokushinsa Notification No. 1121-12 of November 21, 2014). Furthermore, applications for the market approval of ethical Kampo medicines should follow the Kampo-specific notification of "Handling of Ethical Kampo Medicines" (Yakushin Notification No. 804 of June 25, 1980). Data from comparative studies with standard decoctions must be submitted with approval applications according to Yakushin 2 Notification No. 120 of May 31, 1985. The safety, efficacy, and quality of Kampo medicines are comprehensively assured by the Japanese Pharmacopoeia, Good Manufacturing Practice, Good Agricultural and Collection Practices, marketing approval certificate, approval standard, and pharmacovigilance. I believe that the basic framework for the market approval of ethical Kampo medicines has been established as described above. The key factors for the practical application of superior manufacturing technology and research achievements and the promotion of drug development are the specific guidelines for the approval of drugs of herbal origin.

Monte Carlo simulation in nuclear medicine

International Nuclear Information System (INIS)

Morel, Ch.

2007-01-01

The Monte Carlo method allows for simulating random processes by using series of pseudo-random numbers. It became an important tool in nuclear medicine to assist in the design of new medical imaging devices, optimise their use and analyse their data. Presently, the sophistication of the simulation tools allows the introduction of Monte Carlo predictions in data correction and image reconstruction processes. The availability to simulate time dependent processes opens up new horizons for Monte Carlo simulation in nuclear medicine. In a near future, these developments will allow to tackle simultaneously imaging and dosimetry issues and soon, case system Monte Carlo simulations may become part of the nuclear medicine diagnostic process. This paper describes some Monte Carlo method basics and the sampling methods that were developed for it. It gives a referenced list of different simulation software used in nuclear medicine and enumerates some of their present and prospective applications. (author)

Traditional Mediterranean and European herbal medicines.

Science.gov (United States)

Leonti, Marco; Verpoorte, Robert

2017-03-06

Written history allows tracing back Mediterranean and European medical traditions to Greek antiquity. The epidemiological shift triggered by the rise of modern medicine and industrialization is reflected in contemporary reliance and preferences for certain herbal medicines. We sketch the development and transmission of written herbal medicine through Mediterranean and European history and point out the opportunity to connect with modern traditions. An ethnopharmacological database linking past and modern medical traditions could serve as a tool for crosschecking contemporary ethnopharmacological field-data as well as a repository for data mining. Considering that the diachronic picture emerging from such a database has an epidemiological base this could lead to new hypotheses related to evolutionary medicine. The advent of systems pharmacology and network pharmacology opens new perspectives for studying past and current herbal medicine. Since a large part of modern drugs has its roots in ancient traditions one may expect new leads for drug development from novel systemic studies, as well as evidence for the activity of certain herbal preparations.

2017-07-12

Wild animals are widely used in traditional Asian medicine but information from Myanmar is lacking. We show that a wide range of animals are used at a pilgrimage site, mostly for their rendered fats and oils to be used in mixed concoctions. The majority of species were sold to be used to treat aching joints, muscle ache and skin diseases. To assess wildlife for sale for medicinal purposes, and document their medicinal use at Kyaiktiyo, a pilgrimage site at a 1100m tall mountain, with many of the pilgrims climbing to the top. In addition we address legal issues relating to the production and sale of traditional medicine that contain legally protected animals. Four visits were made to Kyaiktiyo, Myanmar, between 2000 and 2017 to quantify animal parts on display and through discussions with vendors to obtain information on medicinal use of these parts. Twenty-three species, mostly mammals, were recorded to be used for traditional medicine. The most common were Chinese serow Capricornis milneedwardsii, Asian elephant Elephas maximus, and Asiatic black bear Ursus thibetanus. Over 600 bodies or body parts were present. Combined, these parts purportedly provided cures or relief for at least 15 ailments or diseases. The most commonly mentioned treatment was that of using rendered animal fats/oils externally to relieve/cure aching joints or muscles. This treatment allegedly provides instant relief to pilgrims after an arduous climb up the mountain. Purported cures for various skin diseases was the next common use for the animal species on offer. Ten of the species observed for sale at Kyaiktiyo are listed as globally threatened, and 15 are protected and cannot be legally traded. Ambiguities in Myanmar's legislation mean that protected animals or their body parts cannot be traded, however traditional medicines can be made out of them provided rules relating to the manufacturing of traditional medicines are adhered to. This study indicated that animals and their parts

Ethnobotanical knowledge and traditional medicinal practices from different parts of the world are of global importance and documentation of ethnobotanical, and ethnopharmacological data is a key prerequisite for further research in the area of herbal medicine and its implementation in clinical practice. An attempt was made to evaluate the scientific output of research related to ethnobotany and herbal medicine in journals indexed in the subject area "Integrative and Complementary Medicine" in the period 2001-2013, in order to ascertain research trends in both subdisciplines. All articles related to ethnobotany and herbal medicine, extracted from journals included in the field of I&C Medicine and published in the period 2001-2013, have been analyzed for general bibliometric data, and specific data: ethnobotanical data (geographic, floristic, pharmacological, sociological and other relevant data) and phytotherapeutic data (type of applied herbal medicine, plant species studied, pharmacological activity of studied plant species and disease and disorder type studied on a particular model). In the studied period, the number of articles dealing with ethnobotany and herbal medicine increased 6.3-fold. Articles related to ethnobotanical studies documented medicinal flora from 81 countries, either giving an overview of overall medicinal flora, or presenting the ethnomedicinal aspect of the use of plants for the treatment of ailments typical to the studied area. Additionally, the authors provided significant information on the methods of use and herbal preparations. In herbal medicine studies, plants, traditional plant remedies, herbal medicinal products and active herbal compounds were tested for many of pharmacological activities (146), with the curative activity emerging as most frequently tested. Out of 39 model systems, most of the studies were carried out under controlled in vitro conditions (4589 articles), followed by rat in vivo (2320), human in vivo (1285), mouse

2017-02-02

Medicinal plants belong to the oldest known health care products that have been used by human beings all over the world and are major components of the formulations used in indigenous system of medicine practiced in many countries. Besides, finding place as health supplements, nutraceuticals, cosmetics, herbal tea etc. there has been a global insurgence of interest, including India, leading to enormous research/activities in the area of medicinal plants. The article is aimed to provide the effort and initiatives of ICMR towards research on medicinal plants and its contributions on consolidation of Indian research on medicinal plants that are very relevant and important in the national context. The various initiatives undertaken by ICMR on research on traditional medicines/medicinal plants in the past are reviewed and documented in this article. The multi-disciplinary, multicentric research initiatives of ICMR have resulted in validation of traditional treatment Kshaarasootra (medicated Ayurvedic thread) for anal fistula, Vijayasar (heart wood of Pterocarpus marsupium Roxb.) for diabetes mellitus, encouraging micro- and macrofilaricidal activity of Shakotak (stem bark of Streblus asper Lour.) in experimental studies an iridoid glycosides fraction isolated from root/rhizomes of Picrorhiza kurroa Royle ex Benth. (designated as Picroliv) for viral hepatitis. Other developmental and compilation of research works on Indian medicinal plants have resulted in publications of the thirteen volumes of quality standards, comprising of 449 Indian medicinal plants; three volumes of 90 phytochemical reference standards; fifteen volumes of review monographs on 4167 medicinal plant species; and one publication each on perspectives of Indian medicinal plants for management of liver disorders, lymphatic filariasis and diabetes mellitus (details available at http://www.icmr.nic.in/mpsite). The ICMR efforts assume special significance in the light of multifaceted use of medicinal plants

Lee, Ah-Ram; Yim, Je-Min; Kim, Won-Il

2012-01-01

Objectives: The aim of this study was to investigate the safety and the efficacy of Korean herbal, western and combination medicine use in patients with abnormal liver function tests. Methods: We investigated nerve disease patients with abnormal liver function tests who were treated with Korean herbal, western and combination medicine at Dong-Eui University Oriental Hospital from January 2011 to August 2011. We compared aspartic aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and total bilirubin (T-bil) levels before and after taking medicine and excluded patients who had liver-related disease when admitted. Results: AST and ALT were decreased significantly in patients who had taken herbal, western medicine. AST, ALT and ALP were decreased significantly in patients who had taken combination medicine. Compare to herbal medicine, AST, ALT and ALP were decreased significantly in patients who had taken western medicine, and ALT and ALP were decreased significantly in patients who had taken combination medicine. There were no significant differences between western and combination medicine. Conclusions: This study suggests that prescribed Korean herbal medicine, at least, does not injure liver function for patients’, moreover, it was shown to be effective in patients with abnormal liver function tests.

Nuclear medicine applications: Summary of Panel 4

International Nuclear Information System (INIS)

Wolf, A.P.

1988-01-01

Nuclear medicine is currently facing a desperate shortage of organic and inorganic chemists and nuclear pharmacists who also have advanced training in nuclear and radiochemistry. Ironically, this shortfall is occurring in the face of rapid growth and technological advances which have made the practice of nuclear medicine an integral part of the modern health care system. This shortage threatens to limit the availability of radiopharmaceuticals required in routine hospital procedures and to impede the development of new diagnostic and therapeutic agents. To redress this need and prevent a similar shortfall in the future, this panel recommends immediate action and a long-term commitment to the following: educating the public on the benefits of nuclear medicine; informing undergraduate and graduate chemistry students about career opportunities in nuclear medicine; offering upper level courses in nuclear and radiochemistry (including laboratory) in universities; establishing training centers and fellowships at the postgraduate level for specialized education in the aspects of nuclear and radiochemistry required by the nuclear medicine profession. 1 tab

The essence of alternative medicine. A dermatologist's view from Germany.

Science.gov (United States)

Happle, R

1998-11-01

In Germany, alternative medicine is presently very popular and is supported by the federal government. When deliberating on the essence of alternative medicine we should simultaneously reflect on the intellectual and moral basis of regular medicine. To provide an epistemological demarcation of the 2 fields, the following 12 theses are advanced: (1) alternative and regular medicine are speaking different languages; (2) alternative medicine is not unconventional medicine; (3) the paradigm of regular medicine is rational thinking; (4) the paradigm of alternative medicine is irrational thinking; (5) the present popularity of alternative medicine can be explained by romanticism; (6) some concepts of alternative medicine are falsifiable and others are not; (7) alternative medicine and evidence-based medicine are mutually exclusive; (8) the placebo effect is an important factor in regular medicine and the exclusive therapeutic principle of alternative medicine; (9) regular and alternative medicine have different aims: coming of age vs faithfulness; (10) alternative medicine is not always safe; (11) alternative medicine is not economic; and (12) alternative medicine will always exist. The fact that alternative methods are presently an integral part of medicine as taught at German universities, as well as of the physician's fee schedule, represents a collective aberration of mind that hopefully will last for only a short time.

In order to assess the choice of the sulphur-iodine thermochemical cycle for massive hydrogen production, a precise knowledge of the concentrations of the gaseous species (HI, I 2 , and H 2 O) in thermodynamic equilibrium with the liquid phase of the HI-I 2 -H 2 O ternary mixture is required, in a wide range of concentrations and for temperatures and pressures up to 300 degrees C and 50 bar. In the companion paper (Part 1) the experimental device was described, which enables the measurement of the total pressure and concentrations of the vapour phase (and thus the knowledge of the partial pressures of the different gaseous species) for the HI-I 2 -H 2 O mixture in the 20-140 degrees C range and up to 2 bar. This (Part 2) article describes the experimental device which enables similar measurements but now in the process domain. The results concerning concentrations in the vapour phase for the HI-I 2 -H 2 O initial mixture (with a global composition) in the 120-270 degrees C temperature range and up to 30 bar are presented. As previously, optical online diagnostics are used, based on recordings of infrared transmission spectra for HI and H 2 O and on UV/visible spectrometry for I 2 . The concentrations measured in the vapour phase are the first to describe the vapour composition under thermophysical conditions close to those of the distillation column. The experimental results are compared with a thermodynamic model and will help us to scale up and optimize the reactive distillation column we promote for the HI section of the sulphur-iodine cycle.

Tian, Changqing; Dou, Chunpeng; Yang, Xinjiang; Li, Xianting [Department of Building Science, School of Architecture, Tsinghua University, Beijing 100084 (People' s Republic of China)

2005-11-01

A test system is built first in order to investigate the instability of the automotive air conditioning (AAC) system with a variable displacement compressor (VDC), and hunting phenomena caused by the large external disturbance in the AAC system with a VDC and a thermal expansion valve, and in the AAC system with a VDC and a fixed-area throttling device are investigated experimentally in part 1 of this paper. The experimental results indicate that there also exist the hunting phenomena in the AAC system with a fixed-area throttling device. The system stability is found to be dependent on the direction of the external disturbance, and the system is apt to cause hunting when the condensing pressure decreases excessively since it may cause two-phase state at the throttling device inlet and make a large disturbance to the system. The piston stroke length will oscillate only when the oscillation amplitudes of forces acting on the wobble plate are great enough, otherwise the piston stroke length will be kept invariable, and then the system instability rule is also suitable for the AAC system with a fixed displacement compressor. From the experimental results, it is concluded that the two-phase flow at the throttling device inlet or at the evaporator outlet is the necessary condition but not sufficient condition for system hunting. Finally, a new concept, conservative stable region, is proposed based on the experimental results and theoretical analysis. (author)

Science.gov (United States)

Panee, Jun

2015-06-01

Bamboo plants play a significant role in traditional Asian medicine, especially in China and Japan. Biomedical investigations on the health-benefiting effects as well as toxicity of different parts and species of bamboo have been carried out worldwide since the 1960s, and documented a wide range of protective effects of bamboo-derived products, such as protection against oxidative stress, inflammation, lipotoxicity, cancer, and cardiovascular disease. Some of these products may interfere with male and female reproductive function, thyroid hormone metabolism, and hepatic xenobiotransformation enzymes. The diversity of bamboo species, parts of the plants available for medicinal use, and different extraction methods suggest that bamboo has great potential for producing a range of extracts with functional utility in medicine.

The general internist cannot be a passive bystander of the anticipated medical revolution induced by precision medicine. This latter aims to improve the predictive and/or clinical course of an individual by integrating all biological, genetic, environmental, phenotypic and psychosocial knowledge of a person. In this article, national and international initiatives in the field of precision medicine are discussed as well as the potential financial, ethical and limitations of personalized medicine. The question is not to know if precision medicine will be part of everyday life but rather to integrate early the general internist in multidisciplinary teams to ensure optimal information and shared-decision process with patients and individuals.

The use of herbs for therapeutic purpose is as old as human history. In Pakistan a major part of population is dependent on the traditional medicine derived from plants for primary health care system. The interest in the use of traditional system of medicine has gained popularity globally. The developed countries are shifting their focus to further research based on the indigenous knowledge collected from aboriginal people. The present study reviews the ethno-medicinal uses of family Apiaceae reported from Pakistan. Out of 167 species reported from Pakistan, 66 are found to be used medicinally. Most commonly treated disorders by use of Apiaceae herbal flora are gastrointestinal tract and liver disorders (28%) followed by cough, cold and respiratory tract problems (11%). The plant parts frequently used are roots (22%) followed by whole plant material (19%), leaf material (18%), fruit (13%), seed (12%), stem, flower, aerial parts (5%) and sap (1%). It is suggested to carry out similar studies for other families to explore the indigenous knowledge for the development of commercial products and to collectively document the scattered existing knowledge.

Scientific investigations and case studies from Asian medicine show that fungi have very promising pharmacological potential. This article provides an overview of the principles of authorization and market access of herbal drugs in Europe, with special reference to Germany. The current status regarding mushrooms is reported, with an aim toward supporting the development of legalized pharmaceutical preparations of medicinal mushrooms in Europe.

[Rational use of medicines].

Science.gov (United States)

Helali, A

2006-12-01

Every body speaks about inappropriate use of medicines and each one gives his own explanation. Politicians are telling about the waste of medicines and the money of their national budget. Citizens are saying that the physicians prescribe more than necessary for treatment and blame them as one part of the financial burden weighting on their family budget. Physicians give different explanation and think that the rational use of medicines is a sort of pressure to limit their freedom to prescribe what it seems to them necessary and better for their patients. Pharmacists dispensing medicines consider the prescription as a physician's prerogative and prefer to stay neutral in this debate. Within this large range of opinions, it is difficult to find general consensus, so that every body take care to not declare his proper opinion about the subject, the causes and the adequate solutions. Finally no changes take place in this issue. However, neither the government as responsible for the citizen's health, nor the health professionals and international organisations, are facing their complete obligations toward the populations by ensuring to them that the medicines are administered according to the health need of the patients, efficacious and safe , in doses that meet their own individual requirements, for an adequate period of time, and at the lower cost, and be secured against misuse by the pharmacist before the delivery to the patients. This is a worthwhile programme, but unfortunately without designate takers or promoters until now.

An effective management system that integrates quality management is essential for a modern nuclear medicine practice. The Nuclear Medicine and Diagnostic Imaging Section of the International Atomic Energy Agency (IAEA) has the mission of supporting nuclear medicine practice in low- and middle-income countries and of helping them introduce it in their health-care system, when not yet present. The experience gathered over several years has shown diversified levels of development and varying degrees of quality of practice, among others because of limited professional networking and limited or no opportunities for exchange of experiences. Those findings triggered the development of a program named Quality Management Audits in Nuclear Medicine (QUANUM), aimed at improving the standards of NM practice in low- and middle-income countries to internationally accepted standards through the introduction of a culture of quality management and systematic auditing programs. QUANUM takes into account the diversity of nuclear medicine services around the world and multidisciplinary contributions to the practice. Those contributions include clinical, technical, radiopharmaceutical, and medical physics procedures. Aspects of radiation safety and patient protection are also integral to the process. Such an approach ensures consistency in providing safe services of superior quality to patients. The level of conformance is assessed using standards based on publications of the IAEA and the International Commission on Radiological Protection, and guidelines from scientific societies such as Society of Nuclear Medicine and Molecular Imaging (SNMMI) and European Association of Nuclear Medicine (EANM). Following QUANUM guidelines and by means of a specific assessment tool developed by the IAEA, auditors, both internal and external, will be able to evaluate the level of conformance. Nonconformances will then be prioritized and recommendations will be provided during an exit briefing. The

Radiation exposure of workers in nuclear medicine

International Nuclear Information System (INIS)

Bujnova, A.

2008-01-01

Nuclear medicine is an interdisciplinary department that deals with diagnosis and therapy using open sources. Therefore workers in nuclear medicine are in daily contact with ionizing radiation and thus it is essential to monitor a radiation load. Each work must therefore carry out monitoring of workers. It monitors compliance with the radiation limits set by law, allows an early detection of deviations from normal operation and to demonstrate whether the radiation protection at the workplace is optimized. This work describes the principles of monitoring of workers in nuclear medicine and monitoring methods for personal dosimetry. In the next section the author specifically deals with personal dosimetry at the Department of Nuclear Medicine St. Elizabeth Cancer Institute, Bratislava (KNM-Ba-OUSA). The main part of the work is to evaluate the results of a one-year monitoring of radiation workers KNM-Ba-OUSA. (author)

2018-01-01

Dementia is a chronic neurodegenerative disease causing progressive and gradual impairment of different brain's cognitive functions. The prevalence of dementia is about 3 to 7% in different parts of the world. The aim of this study was to determine the etiologies of dementia according to the Traditional Persian Medicine scientists' viewpoint and introduce their recommended herbal remedies for this disease. The authors explored six main Traditional Persian Medicine textbooks for the disease of dementia, its etiologies and related recommended herbal treatments. Two main keywords of "Lisarghes" and" Nesyan" were searched for this purpose. Medical databases, including PubMed, Scopus, Google Scholar, and Science Direct were searched for related articles published between 1966 and 2016 to review the pharmacological components and active ingredients of suggested herbal medicines. According to the Traditional Persian Medicine, dementia is resulted from brain dystemperament, a condition caused by cold and moist or cold and dry tempers. To treat this disease, Traditional Persian scientists recommended various herbal remedies. Current studies have demonstrated that some of these medicinal plants have beneficial effects for the aforementioned disease, including acetyl cholinesterase inhibitory function, neuroprotective effects, and memory enhancing role. The Traditional Persian Medicine literature suggested different herbal remedies for treating dementia. Modern studies support the usefulness of some of these medicines. However, the effect of a large number of these remedies has remained unexamined, a matter which needs to be investigated in future researches.

Boukandou Mounanga, Marlaine; Mewono, Ludovic; Aboughe Angone, Sophie

2015-11-04

In sub-Saharan Africa, traditional medicine is widely used in rural and urban areas also. This is essentially due to the prohibitive cost of pharmaceutical-based medicine and the low incomes of a major part of the population. In addition, the efficacies of many of these traditional and plant-based medicines are proven, but the fact remains that certain plants used in traditional medicine have toxic effects. It is in this perspective that we investigated by bibliographic literature on the toxicity of plants used in traditional medicine. It is crucial to gain knowledge on these plant-based medicines prepared and prescribed by practitioners, particularly in terms of toxicity, composition, specific efficacy of disease and to advise practitioners of this alternative medicine on the protection and security of patients.

Phytochemistry and pharmacology of anti-depressant medicinal plants: A review.

Science.gov (United States)

Martins, Jeanette; S, Brijesh

2018-05-16

Stress renders an individual to experience mental pressure and exhaustion which brings about feelings of anxiety, depression, anger and/or other negative emotions. Depression affects a person's state of mind, behaviour, health and is often associated with suicide. The use of anti-depressant drugs as therapeutic agents is associated with symptoms such as, delayed onset of action, side-effects, drug-drug and dietary interactions, sexual dysfunction, cardiac toxicity, etc. Thus, there is need to target these issues and improve current treatment options. Medicinal plants have long been used in discovering novel treatment strategies and compounds with promising roles in treating various disease conditions. There has been an increase, worldwide, in the use of medicinal plants and herbs for developing nutraceuticals for treatment of depression and other psychiatric disorders. Medicinal plants in their natural forms are valuable as they are rich in various phytochemical compounds. These phytochemical compounds have pharmacological roles in treating various diseases conditions; apart from being widely available in nature and commercially beneficial. The phytochemical compounds in plants are constantly being explored through various experimental studies to determine the molecular basis of how medicinal plants work in relation to drugs and diseases and to develop neutraceuticals for improving conditions. This review summarizes 110 medicinal plants and their phytochemical constituents that have been shown to possess anti-depressant activity. This review also highlights the various mechanisms of anti-depressant action of some of these plants and their plant parts like roots, stem, leaves, flowers, fruit or whole plant; phytochemical compounds showing anti-depressant activity such flavanoids, steroids, saponins, sugars, lectins, alkaloids, etc.; and various anti-depressant screening models used such as tail suspension test, forced swim test, chronic unpredictable stress test

2012-08-01

Regenerative medicine is expected to make a significant contribution by development of novel therapeutic treatments for intractable diseases and for improving the quality of life of patients. Many advances in regenerative medicine, including basic and translational research, have been developed and tested in experimental animals; pigs have played an important role in various aspects of this work. The value of pigs as a model species is being enhanced by the generation of specially designed animals through cloning and genetic modifications, enabling more sophisticated research to be performed and thus accelerating the clinical application of regenerative medicine. This article reviews the significant aspects of the creation and application of cloned and genetically modified pigs in regenerative medicine research and considers the possible future directions of the technology. We also discuss the importance of reproductive biology as an interface between basic science and clinical medicine. © 2012 Blackwell Verlag GmbH.

Medicine taking decisions: schizophrenia in comparison to asthma and epilepsy.

Science.gov (United States)

Marland, G R; Cash, K

2005-04-01

This paper outlines a recent PhD study that explored factors underpinning decisions of people with schizophrenia regarding neuroleptic medicine taking. Relevant studies tend to be within the world view of psychiatry, resting on traditional concepts of compliance and insight. These studies examined schizophrenia outwith the context of other illnesses taking a snap shot view of medicine taking decision making, thus de-emphasizing its process. The chosen method of grounded theory (Glaser and Strauss 1967) overcomes these deficiencies. Stage 1 data arose from patient interviews, patients with asthma, epilepsy and schizophrenia contributed (n = 45), carers also sometimes contributed (n = 11), all three conditions being episodic disorders vulnerable to environmental stressors. Stage 2 develops from stage 1, mental health workers involved in the care of people with schizophrenia were interviewed, plus one asthma specialist and one epilepsy specialist (n = 16). Their views were compared to perspectives arising from the patient interviews and were included in the data, out of which an explanatory typology emerged. The three parts of the typology comprise the study's major categories and are labelled as: direct-reactive, deferential-compliant, and active discerning and optimizing. Active discerning and optimizing consists of two stages; experimental-reflective and consolidation. The core category of responsive resolution contains themes which run through all major categories.

Jaundice is a very common symptom especially in the developing countries. It is associated with several hepatic diseases which are still major causes of death. There are many different approaches to jaundice treatment and the growing number of ethnomedicinal studies shows the plant pharmacology as very promising direction. Many medicinal plants are used for the treatment of jaundice, however a comprehensive review on this subject has not been published. The use of medicinal plants in drug discovery is highly emphasized (based on their traditional and safe uses in different folk medicine systems from ancient times). Many sophisticated analytical techniques are emerging in the pharmaceutical field to validate and discover new biologically active chemical entities derived from plants. Here, we aim to classify and categorize medicinal plants relevant for the treatment of jaundice according to their origin, geographical location, and usage. Our search included various databases like Pubmed, ScienceDirect, Google Scholar. Keywords and phrases used for these searches included: “jaundice,” “hyperbilirubinemia,” “serum glutamate,” “bilirubin,” “Ayurveda.” The first part of the review focuses on the variety of medicinal plant used for the treatment of jaundice (a total of 207 medicinal plants). In the second part, possible mechanisms of action of biologically active secondary metabolites of plants from five families for jaundice treatment are discussed. PMID:28860989

Essential medicines (EMs) are those medicines which satisfy the priority health care needs of the population. Although it is a fundamental human right, access to essential medicines has been a big challenge in developing countries particularly for children. WHO recommends assessing the current situations on availability and affordability of EMs as the first step towards enhancing access to them. Therefore, the aim of this study was to assess access to EMs for children based on availability, affordability, and price. We adapted the WHO and Health Action International tools to measure availability, affordability, and prices of EMs. We collected data on 22 EMs for children from 15 public to 40 private sectors' drug outlets in east Wollega zone. Availability was expressed as percentage of drug outlets per sector that stocked surveyed medicines on the day of data collection, and prices were expressed as median price ratio. Affordability was measured as the number of daily wages required for the lowest-paid government unskilled worker (1.04 US $per day) to purchase one standard treatment of an acute condition or treatment for a chronic condition for a month. The average availability of essential medicines was 43 % at public and 42.8 % at private sectors. Lowest priced medicines were sold at median of 1.18 and 1.54 times their international reference prices (IRP) in the public and private sectors, respectively. Half of these medicines were priced at 0.90 to 1.3 in the public sector and 1.23 to 2.07 in the private sector times their respective IRP. Patient prices were 36 % times higher in the private sector than in the public sector. Medicines were unaffordable for treatment of common conditions prevalent in the zone at both public and private sectors as they cost a day or more days' wages for the lowest paid government unskilled worker. Access to EMs to children is hampered by low availability and high price which is unaffordable. Thus, further study on larger scale is

Dangers in the practice of defensive medicine in hemostasis testing for investigation of bleeding or thrombosis: part I--routine coagulation testing.

Science.gov (United States)

Lippi, Giuseppe; Favaloro, Emmanuel J; Franchini, Massimo

2014-10-01

Defensive medicine is a term conventionally used for defining the medical (mal)practice of ordering medically questionable diagnostic testing, procedures, or visits, or to avoid high-risk patients or procedures. The practice of defensive medicine may primarily be aimed to reduce exposure to malpractice liability, to avoid patient criticism regarding "medical inaction," or to avoid "missing" some otherwise potential identifiable defect(s). Although the precise impact of defensive medicine in the field of laboratory testing is difficult to estimate from the current literature, the overuse or inappropriate use of laboratory resources ranges from 23 to 67%, and a large part of this can be attributed to medical liability concerns, with apparently little clinical awareness of the adverse consequences that may be associated with this practice. Essentially, performing inappropriate testing remarkably increases the risk of obtaining false-positive results due to statistical, preanalytical, and analytical reasons, thus triggering further and potentially even more invasive follow-up testing, inappropriate patient management, along with incremental increases of expenditure due to misuse of health care resources. As routine coagulation testing is commonly performed for the screening of patients with bleeding or thrombotic disorders, either a false-negative or a false-positive result may significantly impact on clinical outcomes and health care resources. The aim of this article is to describe the leading causes of physiological, pathological, therapeutic, and spurious variations of the prothrombin time, activated partial thromboplastin time, and D-dimer, as well as the potential clinical consequences emerging from the generation of false-negative and false-positive results with these tests.

During 2012, the USDHHS’s Health Resources and Services Administration funded 12 accredited preventive medicine residencies to incorporate an evidence-based integrative medicine curriculum into their training programs. It also funded a national coordinating center at the American College of Preventive Medicine, known as the Integrative Medicine in Preventive Medicine Education (IMPriME) Center, to provide technical assistance to the 12 grantees. To help with this task, the IMPriME Center established a multidisciplinary steering committee, versed in integrative medicine, whose primary aim was to develop integrative medicine core competencies for incorporation into preventive medicine graduate medical education training. The competency development process was informed by central integrative medicine definitions and principles, preventive medicine’s dual role in clinical and population-based prevention, and the burgeoning evidence base of integrative medicine. The steering committee considered an interdisciplinary integrative medicine contextual framework guided by several themes related to workforce development and population health. A list of nine competencies, mapped to the six general domains of competence approved by the Accreditation Council of Graduate Medical Education, was operationalized through an iterative exercise with the 12 grantees in a process that included mapping each site’s competency and curriculum products to the core competencies. The competencies, along with central curricular components informed by grantees’ work presented elsewhere in this supplement, are outlined as a roadmap for residency programs aiming to incorporate integrative medicine content into their curricula. This set of competencies adds to the larger efforts of the IMPriME initiative to facilitate and enhance further curriculum development and implementation by not only the current grantees but other stakeholders in graduate medical education around integrative medicine

Introduction of generic medicinal products to the market has increased access to modern therapies but also enabled significant reduction in their cost, leading to containment of public expenditures on medicinal products reimbursement. The critical assessment of bioequivalence of any reference medicinal product and its counterpart is based on comparison of their rate and extent of absorption. It is assumed that two medicinal products are bioequivalent when their rate and extent of absorption do not show significant differences when administered at the same dose under similar experimental conditions. Bioequivalent medicinal products are declared to be also therapeutically equivalent and can be used interchangeably. However, despite regulatory declaration, switching from reference to generic drugs is often associated with concerns of healthcare providers about decreased treatment effectiveness or occurrence of adverse drug reactions. The aim of this article is to provide a description of rules that guide registration of generic medicinal products in the European Union and to analyze specific examples from the scientific literature concerning therapeutic equivalence of reference and generic antidepressant and antipsychotic medicinal products.

Validation of immunohistochemistry (IHC) assays is a subject that is of great importance to clinical practice as well as basic research and clinical trials. When applied to clinical practice and focused on patient safety, validation of IHC assays creates objective evidence that IHC assays used for patient care are "fit-for-purpose." Validation of IHC assays needs to be properly informed by and modeled to assess the purpose of the IHC assay, which will further determine what sphere of validation is required, as well as the scope, type, and tier of technical validation. These concepts will be defined in this review, part 3 of the 4-part series "Evolution of Quality Assurance for Clinical Immunohistochemistry in the Era of Precision Medicine."

Amann, I; Heyder, R; Strehl, R

2009-08-01

University medicine in Germany requires significantly higher funding and investment because its tasks not only include health care but also research and teaching. However, over recent decades less and less funding compared to the development of the turnover has been available. This trend is due to decreasing public funding. The diminishing funding has caused a major backlog of investment at German university hospitals. The first part of the article summarizes the investments policies at university hospitals and other hospitals. The second part describes the investment needs in university medicine and exposes risk factors for research, education and health care due to the process of investment planning and realization. Goal-oriented solutions are shown to facilitate investments. The third part discusses several risks caused by insufficient investments in university medicine. There are special risks for research, teaching, and the capacity for innovation in university medicine besides economical and medical risks. Some policies and financial strategies to overcome the backlog in investments are presented. After a summary, the article concludes with some practical examples of further measures to ensure sustainable funding.

2014-01-01

The safety of herbal products has become a foremost apprehension in public health with their recognition and worldwide market growth and due in part to the widespread assumption that natural implies harmless. The global market of medicinal plants has been growing at a rate of 7-10% annually; capitalizing on the growing awareness of herbal and aromatic plants globally. The present study was conducted to assess the physiochemical parameters, microbial contamination and presence of heavy metals. The 24 medicinal plants were collected from open market places of various cities of Pakistan and tested by employing WHO and AOAC guidelines. Medicinal plants were found polluted with wide variety of potentially pathogenic bacterias. Microbial count and levels of arsenic and mercury in some plants were found elevated. The percentage (%) of physiochemical parameters i.e., foreign organic matter, total ash, acid insoluble ash, alcohol soluble extract, water soluble extract and moisture count of these medicinal plants were found statistically noteworthy. The nonexistence of quality control values for medicinal plants has been one of the key lacunas. Quality assurance system and WHO's guidelines on good agricultural and collection practices be methodically enforced in the medicinal plants supply chain i.e., cultivation, collection and distribution, although it is tricky task.

Biological agents have played an important role in the evolution of modern medical therapeutics. Recent advances in biologicals have in part been stimulated by the biotechnology revolution seen over the last several years. Toxicologists need to be aware of the proposed mechanisms and approved and experimental uses of these new biologic agents. Further, controversies about their use, efficacy, cost issues and potential toxicities should be known. Often these drugs are designed for small patient populations thus limiting the availability of human toxicological data bases. This paper reviews the pharmacology and toxicology of three new biologics (recombinant human DNase I, alpha 1-protease inhibitor, and nitric oxide). These agents appear to have important roles in treating specific diseases or disease states seen in pulmonary medicine.

Integrative medicine therapy using traditional Chinese medicine (TCM) combined with western medicine has shown some advantages in treating heart failure (HF), such as holistic concept; multi-target treatment; dialectical logic; personalized therapy; formulae compatibility; and reduction of side effects of western medicine. However, problems still exist in TCM treatment of HF, including non-uniformed categorization of TCM, lack of standardized syndrome differentiation and lack of an evidence base. The future of treatment of HF seems to be focused on reversing ventricular remodeling, improving cardiac rehabilitation, and accelerating experimental research and drug discovery in TCM.

Modeling and experimental study of residual stresses in NOREM hardfacing coatings used in valve parts

International Nuclear Information System (INIS)

Beaurin, G.

2012-01-01

Hardfacing coatings are widely used on the surfaces of parts subjected to drastic loadings. Norem02 alloy, Fe-based, is used in PWR nuclear power plants on valves seating surfaces. Its microstructure consists of a dendritic austenite structure with ferrite islets and carbides. This work tends to demonstrate that for this alloy, metallurgical evolution during the welding process has very little influence on mechanical properties. Tensile behavior was characterized and completed by dilatometry tests in welding process temperature range until 1000 Celsius degrees, in order to identify an elastoplastic model with non linear kinematic hardening rule. Temperature, displacements, distortions and residual stresses were measured during the PTAW (Plasma Transferred Arc Welding) process and used to identify an equivalent thermal loading by solving an inverse problem. Finally, the numerical simulation of the whole process using the EDF FEM software Code-Aster is presented. Predicted temperatures are consistent with experimental ones. In the same way, predicted displacements, residual distortions and residual stresses at the end of the cooling phase are close to experimental measures, validating the modeling strategy presented in this work.

Traditional medicine has been practised in Ghana for centuries with the majority of Ghanaians still patronising the services of traditional healers. Throughout Africa a large number of people use pangolins as a source of traditional medicine, however, there is a dearth of information on the use of animals in folk medicine in Ghana, in particular the use of pangolins. The aim of this study was to determine the prevalent use of pangolins and the level of knowledge of pangolin use among traditional healers in Ghana for the treatment of human ailments. Data was gathered from 48 traditional healers using semi-structured interviews on the traditional medicinal use of pangolin body parts in the Kumasi metropolis of Ghana. The cultural importance index, relative frequency of citation, informant agreement ratio and use agreement values were calculated to ascertain the most culturally important pangolin body part as well as the level of knowledge dissemination among traditional healers with regards pangolin body parts. Our study revealed that 13 body parts of pangolins are used to treat various medicinal ailments. Pangolin scales and bones were the most prevalent prescribed body parts and indicated the highest cultural significance among traditional healing practices primarily for the treatment of spiritual protection, rheumatism, financial rituals and convulsions. Despite being classified under Schedule 1 of Ghana's Wildlife Conservation Act of 1971 (LI 685), that prohibits anyone from hunting or being in possession of a pangolin, our results indicated that the use of pangolins for traditional medicinal purposes is widespread among traditional healers in Ghana. A study on the population status and ecology of the three species of African pangolins occurring in Ghana is urgently required in order to determine the impact this harvest for traditional medical purposes has on their respective populations as current levels appear to be unmonitored and unsustainable.

Animal-based medicines: biological prospection and the sustainable use of zootherapeutic resources

Directory of Open Access Journals (Sweden)

Eraldo M. Costa-Neto

2005-03-01

Full Text Available Animals have been used as medicinal resources for the treatment and relieve of a myriad of illnesses and diseases in practically every human culture. Although considered by many as superstition, the pertinence of traditional medicine based on animals cannot be denied since they have been methodically tested by pharmaceutical companies as sources of drugs to the modern medical science. The phenomenon of zootherapy represents a strong evidence of the medicinal use of animal resources. Indeed, drug companies and agribusiness firms have been evaluating animals for decades without paying anything to the countries from where these genetic resources are found. The use of animals' body parts as folk medicines is relevant because it implies additional pressure over critical wild populations. It is argued that many animal species have been overexploited as sources of medicines for the traditional trade. Additionally, animal populations have become depleted or endangered as a result of their use as experimental subjects or animal models. Research on zootherapy should be compatible with the welfare of the medicinal animals, and the use of their by-products should be done in a sustainable way. It is discussed that sustainability is now required as the guiding principle for biological conservation.Os animais são utilizados como recursos medicinais para o tratamento e alívio de um gama de doenças e enfermidades em praticamente toda cultura humana. A pertinência da medicina tradicional baseada em animais, embora considerada como superstição, não deve ser negada uma vez que os animais têm sido testados metodicamente pelas companhias farmacêuticas como fontes de drogas para a ciência médica moderna. O fenômeno da zooterapia representa uma forte evidência do uso medicinal de recursos animais.

Complementary and alternative medicine (CAM) is a group of diverse medical and healthcare systems, therapies, and products that are not presently considered part of conventional medicine. This article provides an up-to-date review of the efficacy of selected CAM modalities in the management of chronic pain. Findings are presented according to the classification system developed by the National Institutes of Health National Center for Complementary and Alternative Medicine (formerly Office of Alternative Medicine) and are grouped into four domains: biologically based medicine, energy medicine, manipulative and body-based medicine, and mind-body medicine. Homeopathy and acupuncture are discussed separately as "whole or professionalized CAM practices." Based on the guidelines of the Clinical Psychology Division of the American Psychological Association, findings indicate that some CAM modalities have a solid track record of efficacy, whereas others are promising but require additional research. The article concludes with recommendations to pain practitioners.

The incompatibility of traditional Chinese medicines is related to the clinical medication safety, so has attracted wide attentions from the public. With the deepening of studies on the incompatibility of traditional Chinese medicines represented by 18 incompatible herbs, the incompatibility of theory traditional Chinese medicines has raised to new heights. From the origin of incompatibility theory of traditional Chinese medicines, relationship of herbs, harms of incompatible herbs and principle of prevention to toxic effects of specific incompatible medicines, the innovation and development of the traditional Chinese medicine incompatibility theory was explored. Structurally, the incompatibility of traditional Chinese medicines refers to the opposition of two herbs based on seven emotions and clinical experience. The combination of incompatible herbs may lead to human harms, especially latent harm and inefficacy of intervention medicines. The avoidance of the combination of incompatible herbs and the consideration of both symptoms and drug efficacy are the basic method to prevent adverse reactions. The recent studies have revealed five characteristics of incompatible herbs. Toxicity potentiation, toxication, efficacy reduction and inefficacy are the four manifestations of the incompatible relations. The material changes can reflect the effects of toxicity potentiation and toxication of opposite herbs. The accumulation of toxicity and metabolic changes are the basis for latent harms. The antagonistic effect of main efficacies and the coexistence of positive and negative effects are the distinctive part of the incompatibility. The connotation of incompatible herbs plays an important role in the innovation of the traditional Chinese medicine incompatibility theory.

To review and summarize the development during the last 20 years and the current status of cosmetic medicine, i.e., cosmetic surgery, in China, for the healthier development of this specialty in the future. Literature concerned was reviewed, including conference abstracts, papers, and publications, and the present status and problems were analyzed. Cosmetic medicine was recognized as an independent specialty and gained its clear definition. The development of cosmetic medicine is an inevitable trend of the changing medical modules and the developing science and civilization. This trend fulfilled the need of the people. The related problems consisted of a high complication rate, confusion of management, and insufficient specific knowledge in part of the providers. The development of cosmetic medicine is an inevitable trend of the civilization development. For the healthy development of this specialty, scientific management and systemic education for the providers are crucial. Only those who have the plastic surgery background are able to participate in this practice.

The quantitative estimation of various trace element concentrations in medicinal plants is necessary for determining their effectiveness in treating various diseases and for understanding their pharmacological action. Elemental concentrations of some selected medicinal plants of north east India was measured by proton induced X-ray emission (PIXE) and proton induced γ-ray emission (PIGE) techniques. PIXE measurements were carried out using 2.4 MeV collimated protons from the 3 MV tandetron accelerator of NCCCM, Hyderabad (India) while the PIGE measurements were carried out using 3 MeV protons from the same accelerator in the same laboratory. Accuracy and precision of the techniques were assured by analyzing certified reference materials in the same experimental conditions. Various elements of biological importance in man's metabolism were found to be present in varying concentrations in the studied medicinal plants and no toxic heavy metals were detected. The concentration of the various elements in the medicinal plants and their role in treating various diseases are discussed.

Fengdan (Paeonia ostii) is one of Chinese 34 famous medicinal materials. This study investigated the concentrations of Arsenic (As), Chromium (Cr), Cadmium (Cd), Copper (Cu), Lead (Pb), Iron (Fe), Manganese (Mn), and Zinc (Zn) in rhizosphere soils, cortex mouton and seeds of Fengdan planted in a metal mining area, China. The mean concentrations of As, Cd, Cu, and Zn in the rhizosphere soils were above the limits set by the Chinese Soil Environmental Quality Standard (GB 15618-1995). The contamination factor (CF) of Cd was >5, while it was >2for As, Cu, Pb, and Zn in all the soils. The integrated pollution index for all the soils was >3 and ˂ 5. Metal concentrations in the edible parts of Fengdan were in the following decreasing order: Mn>Fe>Zn>Cu>Pb>As>Cr≥Cd. The transfer factor mean values for As, Cu, Cd and Fe in the cortex moutan of old Fengdan (over 6 years) were significantly higher than in young Fengdan. Available metal concentrations, pH and soil organic matter content influenced the metal concentrations of the cortex moutan. The results indicated that mining and smelting operations have led to heavy metals contamination of soils and medicinal parts of Fengdan. The major metal pollutants were elemental Cd, Cu, Pb, and Zn. Heavy metals mainly accumulated in the cortex moutan of Fengdan. The mean concentrations of Cd, Cu, and Pb in the old cortex moutan (over 6 years) were above those of the Chinese Green Trade Standards for Medicinal Plants and Preparations in Foreign Trade (WM/T2-2004).

Access to essential medicines is core to saving lives and improving health outcomes of people worldwide, particularly in the low- and middle-income countries. Having a trained pharmacy workforce to manage the supply chain and safely dispense medicines is critical to ensuring timely access to quality pharmaceuticals and improving child health outcomes. This study measures the impact of an innovative pharmacy assistant training program in the low-income country of Malawi on access to medicines and health outcomes. We employ a cluster quasi-experimental design with pre-and post-samples and decision analytic modeling to examine access to and the use of medicines for malaria, pneumonia, and diarrhea for children less than 5 years of age. Two intervention districts, with newly trained and deployed pharmacy assistants, and two usual care comparison districts, matched on socio-economic, geographic, and health-care utilization indicators, were selected for the study. A baseline household survey was conducted in March 2014, prior to the deployment of pharmacy assistants to the intervention district health centers. Follow-up surveys are planned at 12- and 24-months post-deployment. In addition, interviews are planned with caregivers, and time-motion studies will be conducted with health-care providers at the health centers to estimate costs and resources use. This impact evaluation is designed to provide data on the effects of a novel pharmacy assistant program on pharmaceutical systems performance, and morbidity and mortality for the most common causes of death for children under five. The results of this study should contribute to policy decisions about whether and how to scale up the health systems strengthening workforce development program to have the greatest impact on the supply chain and health outcomes in Malawi.

As part of a large medicinal chemistry program, we wish to develop novel selective estrogen receptor modulators (SERMs) as potential breast cancer treatments using a combination of experimental and computational approaches. However, one of the remaining difficulties nowadays is to fully integrate computational (i.e., virtual, theoretical) and medicinal (i.e., experimental, intuitive) chemistry to take advantage of the full potential of both. For this purpose, we have developed a Web-based platform, Forecaster, and a number of programs (e.g., Prepare, React, Select) with the aim of combining computational chemistry and medicinal chemistry expertise to facilitate drug discovery and development and more specifically to integrate synthesis into computer-aided drug design. In our quest for potent SERMs, this platform was used to build virtual combinatorial libraries, filter and extract a highly diverse library from the NCI database, and dock them to the estrogen receptor (ER), with all of these steps being fully automated by computational chemists for use by medicinal chemists. As a result, virtual screening of a diverse library seeded with active compounds followed by a search for analogs yielded an enrichment factor of 129, with 98% of the seeded active compounds recovered, while the screening of a designed virtual combinatorial library including known actives yielded an area under the receiver operating characteristic (AU-ROC) of 0.78. The lead optimization proved less successful, further demonstrating the challenge to simulate structure activity relationship studies.

Socializing Identity Through Practice: A Mixed Methods Approach to Family Medicine Resident Perspectives on Uncertainty.

Ledford, Christy J W; Cafferty, Lauren A; Seehusen, Dean A

2015-01-01

Uncertainty is a central theme in the practice of medicine and particularly primary care. This study explored how family medicine resident physicians react to uncertainty in their practice. This study incorporated a two-phase mixed methods approach, including semi-structured personal interviews (n=21) and longitudinal self-report surveys (n=21) with family medicine residents. Qualitative analysis showed that though residents described uncertainty as an implicit part of their identity, they still developed tactics to minimize or manage uncertainty in their practice. Residents described increasing comfort with uncertainty the longer they practiced and anticipated that growth continuing throughout their careers. Quantitative surveys showed that reactions to uncertainty were more positive over time; however, the difference was not statistically significant. Qualitative and quantitative results show that as family medicine residents practice medicine their perception of uncertainty changes. To reduce uncertainty, residents use relational information-seeking strategies. From a broader view of practice, residents describe uncertainty neutrally, asserting that uncertainty is simply part of the practice of family medicine.

The popularity of minimally invasive surgical procedures is driving the development of novel, safer and more accurate surgical tools. In this context a multi-part probe for soft tissue surgery is being developed in the Mechatronics in Medicine Laboratory at Imperial College, London. This study reports an optimization procedure using finite element methods, for the identification of an interlock geometry able to limit the separation of the segments composing the multi-part probe. An optimal geometry was obtained and the corresponding three-dimensional finite element model validated experimentally. Simulation results are shown to be consistent with the physical experiments. The outcome of this study is an important step in the provision of a novel miniature steerable probe for surgery.

Siraisi, Nancy G

2012-09-01

History of science and history of medicine are today largely organized as distinct disciplines, though ones widely recognized as interrelated. Attempts to evaluate the extent and nature of their relation have reached varying conclusions, depending in part on the historical period under consideration. This essay examines some characteristics of European medicine from the fifteenth to the early seventeenth century and considers their relevance for the history of science. Attention is given to the range of interests and activities of individuals trained in or practicing medicine, to the impact of changes in natural philosophy, to the role of observation, description, and accumulation of information, and to the exchange of knowledge among the medical community.

Haiyan Fu

2015-01-01

Full Text Available As an effective method, the fingerprint technique, which emphasized the whole compositions of samples, has already been used in various fields, especially in identifying and assessing the quality of herbal medicines. High-performance liquid chromatography (HPLC and near-infrared (NIR, with their unique characteristics of reliability, versatility, precision, and simple measurement, played an important role among all the fingerprint techniques. In this paper, a supervised pattern recognition method based on PLSDA algorithm by HPLC and NIR has been established to identify the information of Hibiscus mutabilis L. and Berberidis radix, two common kinds of herbal medicines. By comparing component analysis (PCA, linear discriminant analysis (LDA, and particularly partial least squares discriminant analysis (PLSDA with different fingerprint preprocessing of NIR spectra variables, PLSDA model showed perfect functions on the analysis of samples as well as chromatograms. Most important, this pattern recognition method by HPLC and NIR can be used to identify different collection parts, collection time, and different origins or various species belonging to the same genera of herbal medicines which proved to be a promising approach for the identification of complex information of herbal medicines.

Neutrons produced by research reactors are being used in nuclear medicine and other medical applications in several ways. The High Flux Reactor (HFR) based in Petten (The Netherlands), owned by the European Commission, has been working increasingly in this field of health care for the European citizen. On the basis of this experience, a survey has been carried out on the main possibilities of neutrons used in nuclear medicine. The most important and most well known is the production of radioisotopes for diagnosis and therapy. Ten million patients receive nuclear medicine in Europe each year, with more than 8 million made with the products issued from research reactors. The survey of the market and the techniques (cyclotron, PET) shows that this market will continue to increase in the future. The direct use of reactors in medicine is actually made by the Boron Neutron capture Therapy (BNCT) for the treatment of glioblastoma, which kills about 15.000 people in Europe each year. For this promising technique, HFR is the most advanced for experimental possibilities and treatment studies. Medical research is also made in other promising fields: the use beam tubes for characterizing of prostheses and bio-medical materials, alpha-immuno therapy products, new types of radioisotopes, new types of illness to be treated by BNCT, etc. (author)

A number of organisations are involved in the field of nuclear medicine education. These include International Atomic Energy Agency (IAEA), World Federation of Nuclear Medicine and Biology (WFNMB), Asia-Oceania Federation of Nuclear Medicine and Biology (AOFNMB), Society of Nuclear Medicine (SNM in USA), European Association of Nuclear Medicine (EANM). Some Universities also have M.Sc courses in Nuclear Medicine. In the Asian Region, an Asian Regional Cooperative Council for Nuclear Medicine (ARCCNM) was formed in 2000, initiated by China, Japan and Korea, with the main aim of fostering the spread of Nuclear Medicine in Asia. The Asian School of Nuclear Medicine (ASNM) was formed in February 2003, with the ARCCNM as the parent body. The Aims of ASNM are: to foster Education in Nuclear Medicine among the Asian countries, particularly the less developed regions; to promote training of Nuclear Medicine Physicians in cooperation with government agencies, IAEA and universities and societies; to assist in national and regional training courses, award continuing medical education (CME) points and provide regional experts for advanced educational programmes; and to work towards awarding of diplomas or degrees in association with recognised universities by distance learning and practical attachments, with examinations. There are 10 to 12 teaching faculty members from each country comprising of physicists, radio pharmacists as well as nuclear medicine physicians. From this list of potential teaching experts, the Vice-Deans and Dean of ASNM would then decide on the 2 appropriate teaching faculty member for a given assignment or a course in a specific country. The educational scheme could be in conjunction with the ARCCNM or with the local participating countries and their nuclear medicine organisations, or it could be a one-off training course in a given country. This teaching faculty is purely voluntary with no major expenses paid by the ASNM; a token contribution could be

Fish and aquatic invertebrates deserve evidence-based medicine. Pharmacologic information is available; most pharmacokinetic studies are derived from the aquaculture industry and extrapolated to ornamental fish. Conversely, advanced diagnostics and information regarding diseases affecting only ornamental fish and invertebrates require more peer-reviewed experimental studies; the examples of carp edema virus, sea star wasting disease, seahorse nutrition, and gas bubble disease of fish under human care are discussed. Antinociception is also a controversial topic of growing interest in aquatic animal medicine. This article summarizes information regarding new topics of interest in companion fish and invertebrates and highlights some future avenues for research. Copyright © 2017 Elsevier Inc.

In this paper the practical problem of nuclear medicine gamma counters calibration has been solved by using dose calibrators CRC-15R with standard error ±5%. The samples from technetium generators have been measured both by dose calibrators CRC-15R and gamma counter ICN Gamma 3.33 taking into account decay correction. Only the linear part of the curve has practical meaning. The advantage of this procedure satisfies the requirements from international standards: the calibration of sources used for medical exposure be traceable to a standard dosimetry laboratory and radiopharmaceuticals for nuclear medicine procedures be calibrated in terms of activity of the radiopharmaceutical to be administered.

Analysis of Dynamic Fracture Compliance Based on Poroelastic Theory - Part II: Results of Numerical and Experimental Tests

Science.gov (United States)

Wang, Ding; Ding, Pin-bo; Ba, Jing

2018-03-01

In Part I, a dynamic fracture compliance model (DFCM) was derived based on the poroelastic theory. The normal compliance of fractures is frequency-dependent and closely associated with the connectivity of porous media. In this paper, we first compare the DFCM with previous fractured media theories in the literature in a full frequency range. Furthermore, experimental tests are performed on synthetic rock specimens, and the DFCM is compared with the experimental data in the ultrasonic frequency band. Synthetic rock specimens saturated with water have more realistic mineral compositions and pore structures relative to previous works in comparison with natural reservoir rocks. The fracture/pore geometrical and physical parameters can be controlled to replicate approximately those of natural rocks. P- and S-wave anisotropy characteristics with different fracture and pore properties are calculated and numerical results are compared with experimental data. Although the measurement frequency is relatively high, the results of DFCM are appropriate for explaining the experimental data. The characteristic frequency of fluid pressure equilibration calculated based on the specimen parameters is not substantially less than the measurement frequency. In the dynamic fracture model, the wave-induced fluid flow behavior is an important factor for the fracture-wave interaction process, which differs from the models at the high-frequency limits, for instance, Hudson's un-relaxed model.

Addiction is a chronic and recurring disease that recurrence phenomenon is the most important challenge in treatment of this disease. Recent experiences have shown that synthetic drugs have undesirable side effects. Recent studies on medicinal plants have shown that they might be effective in treatment of different stages of addiction with lower side effects and costs. The aim of this study was to review the effects of medicinal plants in the treatment of morphine addiction in experimental animals. In this review article, by using keywords of morphine, withdrawal, and plants or herbal medicine in databases of indexing cites, desired articles were obtained since 1994. Inclusion criteria for selecting articles were the articles related to application of medicinal plants in decreasing symptoms resulting from morphine withdrawal were selected. Results of this study on experimental studies have shown that medicinal plants such as Trachyspermum copticum L and Melissa officinalis decrease the symptoms of withdrawal syndrome in a dose-dependent. Also, medicinal plants like Avena sativa, Hypericum perforatu, Passiflora incarnate, Valeriana officinalis, Satureja hortensis L, and Mentha piperita can have effects on behavior, emotions, and other problems of addicts, decreasing withdrawal symptoms. Results of this study showed that medicinal plants can be effective in controlling deprivation, decreasing dependency creation, and possibly DETOXIFICATION: of opioid addicts. © The Author(s) 2015.

Global view on radiation protection in medicine

Vano, E.

2011-01-01

When planning good management of ionising radiation in medicine, key factors such as ensuring that health professionals work together and convincing them that radiation protection (RP) represents a substantial part of the quality management system in their clinical practice are of utmost importance. The United Nations Scientific Committee on the Effects of Atomic Radiation has decided that one of the thematic priorities will be medical radiation exposure of patients. The International Commission on Radiological Protection has recently updated the report on RP in medicine and continues to work on focused documents centred on specific areas where advice is needed. The roles of the International Atomic Energy Agency, World Health Organization and the European Commission, in the area of RP in medicine, are described in the present document. The industry, the standardisation organisations as well as many scientific and professional societies are also dedicating significant effort to radiation safety aspects in medicine. Some of the efforts and priorities contemplated in RP in medicine over the coming years are suggested. The best outcome will be accomplished when all the actors, i.e. medical doctors, other health professionals, regulators, health authorities and the industry manage to work together. (authors)

On Heidegger, medicine, and the modernity of modern medical technology.

Science.gov (United States)

Brassington, Iain

2007-06-01

This paper examines medicine's use of technology in a manner from a standpoint inspired by Heidegger's thinking on technology. In the first part of the paper, I shall suggest an interpretation of Heidegger's thinking on the topic, and attempt to show why he associates modern technology with danger. However, I shall also claim that there is little evidence that medicine's appropriation of modern technology is dangerous in Heidegger's sense, although there is no prima facie reason why it mightn't be. The explanation for this, I claim, is ethical. There is an initial attraction to the thought that Heidegger's thought echoes Kantian moral thinking, but I shall dismiss this. Instead, I shall suggest that the considerations that make modern technology dangerous for Heidegger are simply not in the character - the ethos - of medicine properly understood. This is because there is a distinction to be drawn between chronological and historical modernity, and that even up-to-date medicine, empowered by technology, retains in its ethos crucial aspects of a historically pre-modern understanding of technology. A large part of the latter half of the paper will be concerned with explaining the difference.

With the development of ever-expanding synthetic methodologies, a medicinal chemist's toolkit continues to swell. However, with finite time and resources as well as a growing understanding of our field's environment impact, it is critical to refine what can be made to what should be made. This review seeks to highlight multiple cheminformatic approaches in drug discovery that can influence and triage design and execution impacting the likelihood of rapidly generating high-value molecules in a more sustainable manner. This strategy gives chemists the tools to design and refine vast libraries, stress "druglikeness", and rapidly identify SAR trends. Project success, i.e., identification of a clinical candidate, is then reached faster with fewer molecules with the farther-reaching ramification of using fewer resources and generating less waste, thereby helping "green" our field.

The history of veterinary medicine is closely tied to the development of human medicine. Evidence of animal medicine has been found in ancient civilizations, such as those of the Hindu, Babylonians, Hebrews, Arabs, Greeks, and Romans. Ancient Indian literature in the form of the holy Vĕda, Purăna, Brăhmaņa, epics, etc. is flooded with information on animal care. The Purăņa are ancient scriptures discuss varied topics like devotion to God and his various aspects, traditional sciences like Ayurvĕda, Jyŏtişa (Astrology), cosmology, concepts like dharma, karma, reincarnation and many others. The treatment of animal diseases using Ayurvedic medicine has been mentioned in Garudapurăna, Agnipurăņa, Atri-samhită, Matsyapurăņa and many other texts. The Garudapurăņa is one of the important Săttvika purăna, the subject matter is divided into two parts, viz. Pŭrvakhaņda (first part) and an Uttarakhaņda (subsequent part). Gavăyurvĕda, Gajăyurvĕda narrated briefly and Aśvăyurvĕda described detailly in Pŭrvakhaņda.

Evaluation and Visualization of Surface Defects - a Numerical and Experimental Study on Sheet-Metal Parts

International Nuclear Information System (INIS)

Andersson, A.

2005-01-01

The ability to predict surface defects in outer panels is of vital importance in the automotive industry, especially for brands in the premium car segment. Today, measures to prevent these defects can not be taken until a test part has been manufactured, which requires a great deal of time and expense. The decision as to whether a certain surface is of acceptable quality or not is based on subjective evaluation. It is quite possible to detect a defect by measurement, but it is not possible to correlate measured defects and the subjective evaluation. If all results could be based on the same criteria, it would be possible to compare a surface by both FE simulations, experiments and subjective evaluation with the same result.In order to find a solution concerning the prediction of surface defects, a laboratory tool was manufactured and analysed both experimentally and numerically. The tool represents the area around a fuel filler lid and the aim was to recreate surface defects, so-called 'teddy bear ears'. A major problem with the evaluation of such defects is that the panels are evaluated manually and to a great extent subjectivity is involved in the classification and judgement of the defects. In this study the same computer software was used for the evaluation of both the experimental and the numerical results. In this software the surface defects were indicated by a change in the curvature of the panel. The results showed good agreement between numerical and experimental results. Furthermore, the evaluation software gave a good indication of the appearance of the surface defects compared to an analysis done in existing tools for surface quality measurements. Since the agreement between numerical and experimental results was good, this indicates that these tools can be used for an early verification of surface defects in outer panels

Ethics and integrative medicine: moving beyond the biomedical model.

Guinn, D E

2001-01-01

For the most part, those who have written on the ethics of complementary and alternative medicine (CAM) and integrative medicine have attempted simply to apply traditional bioethics (in the form of principles of autonomy, beneficence, nonmaleficence, and justice) to this new area of healthcare. In this article I argue that adopting the practices of CAM requires a new ethical understanding that incorporates the values implicit in those practices. The characteristics of CAM and conventional medicine can be translated into the language of healthcare values in a variety of ways. I suggest that they support 5 core values: integrated humanity, ecological integrity, naturalism, relationalism, and spiritualism. Characteristics of both CAM and conventional medicine are present in value. What is now thought of as principlism is, in this understanding, simply a subset within these values.

The market for hospital medicine in Denmark

Full Text Available Pharmaceutical expenditure growth has outpaced GDP and healthcare expenditure growth rates in Denmark as in most OECD countries for the last decade. A major part of this increase was due to high growth rates in specialist areas that are typically located in hospital settings. Yet the market for hospital medicines and their procurement are still poorly understood. The present paper characterises the market for hospital medicines in Denmark in terms of its organisation and developments between 2005 and 2009. In Denmark hospital medicines are publicly financed and procurement is centrally organised. 98% of all medicines administered at Danish public hospitals are purchased through a public procurement agency by means of public tenders. Using data on actual contract prices we decompose pharmaceutical expenditure growth into the contributions from newly introduced medicines, price and volume increases and use summary statistics to compare market performance in both sectors. The market for hospital medicine is more concentrated than the pharmaceutical retail sector and the share of generics and parallel imported products is significantly lower. Between 2005 and 2009 expenditures for hospital medicines more than doubled -accounting for almost 40% of the total Danish pharmaceutical market in 2009. Price increases however - although positive and higher than in the pharmaceutical retail sector - were only moderate. The majority of the expenditure growth was due to an increase in utilisation and the introduction of new medicines in the hospital sector. Centralised tendering may therefore have important implications for competition and industry structure in the long run.

Several reports and books over the past decade have summarized bone measurement methods. This chapter serves as an update on those with particular reference to nuclear medicine approaches to bone density and skeletal uptake. Bone densitometry approaches include singe-photon absorptiometry(SPA) and dual-photon absortiometry neutron activation (DPA) of calcium, Compton scattering, ultrasound measurements and uptake of diphosphonates. Of these only SPA and DPA are used clinically; the other methods are largely experimental or investigational. Radiographic morphometry, radiographic indices, and X-ray QCT are dealt with

Over the centuries, a significant part of the Brazilian fauna is widely sold, more specifically in retail stores or street markets. The objective was to characterize the sale of medicinal animals in five large northeast cities. Information about the sale of zootherapeutic items was obtained in the cities of Aracaju-SE, Fortaleza-CE, Maceio-AL, Recife-PE, and Salvador-BA. A total of 68 animal species were sold for medicinal purposes in the cities studied; these are the first results on the use and sale of zootherapeutics in the markets of Aracaju, Fortaleza, and Salvador and first recorded on the medicinal use of the Achatina fulica, Trachycardium muricatum, Philodryas olfersii, Desmodus rotundus, and Leptodactylus vastus. Knowledge of the fauna utilized popular medicine is indispensable for conservation, demonstrating that research on this subject is necessary to determine appropriate practices for the management of the fauna.

[Nature as magician: on the Paracelsus heritage of modern medicine].

Science.gov (United States)

Heinz, Schott

2010-01-01

The concept of "natural magic" (magia naturalis) was very important for medicine and natural science of the early modem period. It stressed a new scientific world view (Weltanschauung) moving away from "supernatural" (superstitious) perceptions and trying to explain all spectacular marvels as results of natural processes. So, Nature (natura), often personified as a female figure, was considered as a (female) magician. Physicians and naturalists should learn from her art to become able to imitate and accomplish her work. In particular this concept was relevant for the al-chemical and magical medicine as the writings of PARACELSUS show. He perceived like many of his contemporaries Nature as a servant of God producing all things according to his will supplying them with "signatures" indicating the scholar (philosophus) their hidden ("natural") powers. The iconography and emblematics of the early modem period--partly directly influenced by the paracelsian thinking--illustrate in different ways the concept of natural magic. Especially the hierarchy God--Nature--Human and the phenomena of light representing divine wisdom and power were imagined. It is remarkable, that also during the enlightenment in regard to artificial electricity and animal magnetism analogous ideas appeared in connection with the light imagery (ether, fluidum). Finally, the romantic natural philosophy dealt with them intensively, and they stimulated not only natural scientific respectively (neuro) physiological, but also psychological (experimental) research.

Hamideh khorrampazouh

2018-02-01

Full Text Available Introduction: Enema or ‘hoqne’ is a therapeutic approach used for a wide range of diseases in the Iranian traditional medicine. The use of this method dates back to thousands of years to Hippocrates and Galen. The aim of this study was to review the history of enema and its methods and indices in the Iranian medicine and other complementary medicine.Methods: This review study was conducted on the Iranian medicine textbooks and articles published in the international databases, including Google Scholar, PubMed, Embase, and Scopus, as well as the Iranian databases, such as SID and Magiran. The searching process was performed using the following keywords: ‘Hoqne’, ‘Enema’, ‘Vasta’, ‘Basta’, and ‘Complementary and Alternative Medicine (CAM’. There was no limitation regarding the publication data of the included studies.Result: In the Iranian medicine, the term “hoqne” is equivalent to enema. Enema is used in various diseases of the brain, respiratory system, digestive system, urogenital system, and musculoskeletal system, as well as systemic diseases. Enema is one of the five main therapies in the Indian medicine or Ayurveda. In other types of complementary medicine, including Chinese medicine, this procedure has therapeutic applications. Although enema has been recognized as a diagnostic method in modern medicine, it has been considered as a therapeutic approach in the recent years.Conclusion: According to the findings of the reviewed studies, enema is a major therapeutic focus in complementary medicine, part of which has been confirmed in the recent studies. Given the low side effects and high success rate of this treatment, it can be used as a supplemental therapy for the management of poisoning, febrile seizures, prolonged functional constipation, and chronic kidney disease, as well as the prevention of swelling. However, this theory requires further investigation and targeted clinical trials. This method has been

Medical humanities’ challenge to medicine

Science.gov (United States)

Macnaughton, Jane

2015-01-01

Medicine is predicated on a view of human nature that is highly positivist and atomistic. This is apparent in the way in which its students are taught, clinical consultations are structured and medical evidence is generated. The field of medical humanities originally emerged as a challenge to this overly narrow view, but it has rarely progressed beyond tinkering around the edges of medical education. This is partly because its practitioners have largely been working from within a pervasive medical culture from which it is difficult to break free, and partly because the field has been insufficiently armed with scholarly thinking from the humanities. This is beginning to change and there is a sign that research in medical humanities has the potential to mount a persuasive challenge to medicine’s ways of teaching, working and finding out. This article problematizes medicine’s narrow viewpoint, grounding its critique in philosophical ideas from phenomenology and pragmatism. I will reflect upon the historical context within which medical humanities has emerged and briefly examine specific examples of how its interdisciplinary approach, involving humanities scholars with clinicians and medical scientists, may develop new research directions in medicine.

Education in the ambulatory setting should be an integral part of undergraduate medical education. However, previous studies have shown education in this setting has been lacking in medical school. Ambulatory education occurs on some internal medicine clerkships. The extent of this education is unclear. The purpose of this survey was to assess the structure, curriculum, assessment methods, and barriers to implementation of ambulatory education on the internal medicine clerkship. An annual survey of institutional members of the Clerkship Directors in Internal Medicine (CDIM) was done in April 2010. The data were anonymous and descriptive statistics were used to summarize responses. Free text results were analyzed using qualitative techniques. The response rate was 75%. The majority of respondents had a required ambulatory component to the clerkship. Ambulatory experiences distinct from the inpatient internal medicine experience were common (46%). Integration with either the inpatient experiences or other departmental clerkships also occurred. The majority of ambulatory educational experiences were with generalists (74%) and/or subspecialists (45%). The most common assessment tool was the National Board of Medical Examiners (NBME) ambulatory shelf exam. Thematic analysis of the question about how practice based learning was taught elicited four major themes: Not taught; taught in the context of learning evidence based medicine; taught while learning chronic disease management with quality improvement; taught while learning about health care finance. Barriers to implementation included lack of faculty and financial resources. There have been significant increases in the amount of time dedicated to ambulatory internal medicine. The numbers of medical schools with ambulatory internal medicine education has increased. Integration of the ambulatory experiences with other clerkships such as family medicine occurs. Curriculum was varied but difficulties with dissemination

Traditional medicines, HIV, and related infections: workshop 2C.

Patel, M; Bessong, P; Liu, H

2011-04-01

Traditional medicines are an integral part of health care worldwide, even though their efficacy has not been scientifically proven. HIV-infected individuals may use them singularly or in combination with conventional medicines. Many in vitro studies have proven the anti-HIV, anti-Candida, and anti-herpes simplex virus potential of traditional plants and identified some of the mechanisms of action. Very few in vivo studies are available that involve a small number of participants and show controversial results. In addition, knowledge is limited of the role of traditional medicines in the enhancement of the immune system. The use of traditional medicines with antiretroviral drugs (ARVs) has created a problem because drug interactions compromise the efficacy of ARVs. Several currently popular plants have been studied in the laboratory for their interaction with ARVs, with disadvantageous results. Unfortunately, no clinical trials are available. The science of traditional medicines is relatively new and is at present being modernized worldwide. However, there are still ethical issues regarding traditional medicines that need to be addressed-for example, regulations regarding quality control and standardization of medicines, regulation and education of healers who deliver these medicines, and unregulated clinical trials. The workshop addressed the following questions about traditional medicine and their use in HIV infection: What are the mechanisms of action of anti-HIV traditional medicines? Should traditional medicines be used in conjunction with ARV? Do traditional medicines enhance the immune system? Should medicinal plants be used for the control of oral infections associated with HIV? What are the ethical issues surrounding the use of traditional medicines for the treatment of HIV and associated infections?

Plants were an essential part of foraging for food and health, and for centuries remained the only medicines available to people from the remote mountain regions. Their correct botanical provenance is an essential basis for understanding the ethnic cultures, as well as for chemical identification of the novel bioactive molecules with therapeutic effects. This work describes the use of herbal medicines in the Beskid mountain ranges located south of Krakow and Lviv, two influential medieval centers of apothecary tradition in the region. Local botanical remedies shared by Boyko, Lemko, and Gorale ethnic groups were a part of the medieval European system of medicine, used according to their Dioscoridean and Galenic qualities. Within the context of ethnic plant medicine and botanical classification, this review identified strong preferences for local use of St John's-wort ( Hypericum perforatum L.), wormwood ( Artemisia absinthium L.), garlic ( Allium sativum L.), gentian ( Gentiana lutea L.), lovage ( Levisticum officinale W.D.J. Koch), and lesser periwinkle ( Vinca minor L.). While Ukrainian ethnic groups favored the use of guilder-rose ( Viburnum opulus L.) and yarrow ( Achillea millefolium L.), Polish inhabitants especially valued angelica ( Angelica archangelica L.) and carline thistle ( Carlina acaulis L.). The region also holds a strong potential for collection, cultivation, and manufacture of medicinal plants and plant-based natural specialty ingredients for the food, health and cosmetic industries, in part due to high degree of biodiversity and ecological preservation. Many of these products, including whole food nutritional supplements, will soon complement conventional medicines in prevention and treatment of diseases, while adding value to agriculture and local economies.

In recent years, more and more research shows that the pharmacokinetic parameter of traditional Chinese medicine can be affected by the disease states. It's possible that drug metabolic enzymes, transporters, cell membrane permeability and the change of microbes group could be interfered with physiological and pathological changes, which enables the pharmacokinetics of traditional Chinese medicine in the body to be altered, including the process of absorption, distribution, metabolism and excretion, and then the pharmacokinetic parameters of traditional chinese medicine are altered. It's found that investigating the pharmacokinetic of traditional Chinese medicine in the pathological state is more useful than that of in normal state because the great part of traditional Chinese medicine is mainly used to treat disease. This article reflects the latest research on the pharmacokinetic of traditional Chinese medicine in the disease state such as diabete, cerebral ischemia, liver injury, inflammatory disease, nervous system disorders and fever in order to provide certain reference for clinicians designing reasonable administration dose.

Nuclear Medicine Imaging Devices. Chapter 11

Imaging forms an important part of nuclear medicine and a number of different imaging devices have been developed. This chapter describes the principles and technological characteristics of the main imaging devices used in nuclear medicine. The two major categories are gamma camera systems and positron emission tomography (PET) systems. The former are used to image γ rays emitted by any nuclide, while the latter exploit the directional correlation between annihilation photons emitted by positron decay. The first section of this chapter discusses the principal components of gamma cameras and how they are used to form 2-D planar images as well as 3-D tomographic images (single photon emission computed tomography (SPECT)). The second section describes related instrumentation that has been optimized for PET data acquisition. A major advance in nuclear medicine was achieved with the introduction of multi-modality imaging systems including SPECT/computed tomography (CT) and PET/CT. In these systems, the CT images can be used to provide an anatomical context for the functional nuclear medicine images and allow for attenuation compensation. The third section in this chapter provides a discussion of the principles of these devices.

The study was conducted during spring and summer periods in 2010 and 2011 through face-to-face interview method to determine the local names, used parts, and medicinal usages of the determined plants. The plant samples collected from the study area were pressed, dried, and labeled according to the herbarium techniques, and identified. Totally 64 plant taxa belonging to 53 genera and 29 families were used by local people for different medicinal purposes in the area. The families including the highest number of taxa were Rosaceae (11 species), Asteraceae (6 species) and Lamiaceae (5 species). The species with the highest number of usage as herbal medicine were Urtica dioica, Anthemis cretica subsp. iberica, Petroselinum crispum,Allium cepa, Rheum ribes, Rosa dumalis subsp. boissieri var. boissieri and Vitis vinifera. Fruits and flowers were the most widely used parts of the plants. Decoction was the main method for using, and the primary therapeutic use of herbal remedies was for the respiratory system diseases such as cold, cough, asthma, and bronchitis.This study was the first carried out on 20 plant taxa used as traditional medicine, and the use of 28 taxa were recorded for the first time in Turkey. For maintaining the knowledge on traditional medicine, urgent studies should be carried out for recording before they have been completely lost. (author)

Since the ancient world relations exist between music and medicine. In the prehistoric music, dance, rhythm and religious practice were important parts of shamanism and early medical procedures. Important philosophers of the classic period already began with the scientific research of musical and medical questions. During the middle age convents conserved ancient knowledge. They offered medical care and taught the ancient knowledge of medicine, arts and music. The Gregorian choral was created. Traditions of popular believe expressed the relations between music and medicine. The Renaissance became the great époque of art, music and science. Leonardo da Vinci and Andreas Vesalius presented a new style of artistic working and scientific knowledge. Also the basics of western music, like tonality was developed. With the separation of scientific subjects in natural sciences and humanities, the relationships between music and medicine fall into oblivion. During the classic and romantic era music and art were important parts of cultural live of the well educated society. With the development of neurology, psychiatry and psychoanalysis more physicians and scientists were interested in musical questions. Questions about the role of music in human behavior and the ancient method to use music in medical treatment became popular. In the early 20th century the music therapy was developed. Today the effects of music to the human brain are investigated with radionuclear methods. A lot of investigations showed the effect of music and music performance to humans. Music plays an important part in psychotherapy, therapeutic pedagogy and medical care, the importance of music and music therapy increases. In the 80ies of the 20th century the performing arts medicine was developed, which asks for the medical problems of performing musicians. © Georg Thieme Verlag KG Stuttgart · New York.

Creating medico-legal opinion is a sophisticated investigative, analytical, decision-making and creative process. Forensic medicine specialist in cooperation with clinical medicine consultants, on the basis of evidence analysis, which was gathered during procedures and contained in the acts has to create an objective and essential opinion. This opinion is a vital, very important and irreplaceable proof in every case. Judicial body consults with forensic medicine specialist or specialists if there are circumstances for settlement of which there is a need of classified informations - art. 193 of Penalty Code. Forensic medicine specialists face many difficulties which may have effect on quality, positiveness of opinion, compliance with the deadline, increasing expectancy of judicial body or sides. It is very difficult to find clinical specialists which except their clinical knowledge have basic knowledge about law, the role and duties of an court expert. In this article we discuss creating-opinion problems, role and position of court expert in confrontation with expectations of judicial body and the Justice with particular emphasis on medical mistakes and assessment of medical proceedings. We show the complexity of creating of medical opinions, especially these institutional.

Why Cannot Today’s Medicine Tolerate Man?

Full Text Available Today, anyone who has travelled a little through history or reflected on social systems knows that although social systems are established and designed to satisfy our needs and demands, they have needs of their own which guarantee their life and may precede our needs. Hence, these systems, which were supposed to serve us indisputably like the genie, make us serve them in different ways. Medicine is one of such social systems which were undoubtedly established to satisfy our vital need to care and cure. To exist and develop, medicine needs to know and control personal and social conditions, and to actualize this need, it needs knowledge, money, and, perhaps prior to all of these, it needs to be trusted. To know man, he should be completely uncovered, observable, and dissected into his parts and the relationship between his parts should be explained in simple models. And to direct the condition toward maximum health, men should be converted into statistical entities and their individual differences, conditions, and narratives have to be ignored so that they become predictable and, consequently, controllable creatures. The story of relative, and almost necessary, conflict between man and medicine is as simple as it is explained. Before we go any further into the discussion, we should remember that a real man, with his whole phenomenological world and new-emergent and unique properties of autonomy and consciousness, may suddenly behave like a joker and disturb all the rules of medicine's play. It is natural that such subtleties cannot be tolerated by a materialistic model which is relying on knowledge of mechanistic organization of parts. The aim of this theoretical essay was to increase the readers’ awareness of biomedical model restrictions and organized cruelties it imposes on man in practice and theory. The discussion of alternate models which we are turning to recently has been undertaken in other essays.

The carbon isotope ratios and contents of mineral elements in leaves of Chinese medicinal plants

International Nuclear Information System (INIS)

Lin Zhifang; Sun Guchou; Wang Wei

1989-01-01

Leaf carbon isotope ratios and 13 kinds of mineral elements were measured on 36 species of common Chinese medicinal plants in a subtropical monsoon forest of Ding Hu Shan in Guangdong Province. The .delta.13C value were from -26.4 to -32.6%, indicating that all of the species belonged the photosynthetic C3 types. The relative lower value of δ13C was observed in the life form of shrubs. The contents of 7 elements (N, P, K, Ca, Na Mg, Si) were dependent upon the species, life form, medicinal function and medicinal part. Herb type medicine and the used medicinal part of leaves or whole plant showed higher levels of above elements than the others. Among the nine groups with different medicinal functions, it was found that more nitrogen was in the leaves of medicinal plants for hemophthisis, hypertension and stomachic troubles, more phosphorus and potassium were in the leaves for cancer and snake bite medicines, but more calcium and magnesium were in the leaves for curing rheumatics. Ferric, aluminium and manganese were the main composition of microelements in leaves. There were higher content of ferric in leaves for hemophthisis medicine, higher zinc in leaves for cold and hypertension medicine, and higher Cup in leaves of stomachic medicine. It was suggested that the pattern of mineral elements in leaves of Chinese medicinal plants reflected the different properties of absorption and accumulation. Some additional effect due to the high content of certain element might be associated with the main function of that medicine

Purpose. To investigate the therapeutic effects of topical administration of antioxidant medicinal plant extracts in a mouse model of experimental dry eye (EDE). Methods. Eye drops containing balanced salt solution (BSS) or 0.001%, 0.01%, and 0.1% extracts were applied for the treatment of EDE. Tear volume, tear film break-up time (BUT), and corneal fluorescein staining scores were measured 10 days after desiccating stress. In addition, we evaluated the levels of interleukin- (IL-) 1β, tumor necrosis factor- (TNF-) α, IL-6, interferon- (IFN-) γ, and IFN-γ associated chemokines, percentage of CD4+C-X-C chemokine receptor type 3 positive (CXCR3+) T cells, goblet cell density, number of 4-hydroxy-2-nonenal (4-HNE) positive cells, and extracellular reactive oxygen species (ROS) production. Results. Compared to the EDE and BSS control groups, the mice treated with topical application of the 0.1% extract showed significant improvements in all clinical parameters, IL-1β, IL-6, TNF-α, and IFN-γ levels, percentage of CD4+CXCR3+ T cells, goblet cell density, number of 4-HNE-positive cells, and extracellular ROS production (P model mice.

The Role of Damage-Associated Molecular Patterns (DAMPs in Human Diseases; Part II: DAMPs as diagnostics, prognostics and therapeutics in clinical medicine

Directory of Open Access Journals (Sweden)

Walter G. Land

2015-05-01

Full Text Available This article is the second part of a review that addresses the role of damage-associated molecular patterns (DAMPs in human diseases by presenting examples of traumatic (systemic inflammatory response syndrome, cardiovascular (myocardial infarction, metabolic (type 2 diabetes mellitus, neurodegenerative (Alzheimer’s disease, malignant and infectious diseases. Various DAMPs are involved in the pathogenesis of all these diseases as they activate innate immune machineries including the unfolded protein response and inflammasomes. These subsequently promote sterile autoinflammation accompanied, at least in part, by subsequent adaptive autoimmune processes. This review article discusses the future role of DAMPs in routine practical medicine by highlighting the possibility of harnessing and deploying DAMPs either as biomarkers for the appropriate diagnosis and prognosis of diseases, as therapeutics in the treatment of tumours or as vaccine adjuncts for the prophylaxis of infections. In addition, this article examines the potential for developing strategies aimed at mitigating DAMPs-mediated hyperinflammatory responses, such as those seen in systemic inflammatory response syndrome associated with multiple organ failure.

Full Text Available ABSTRACT Scientific and technological breakthroughs have compelled the current players in drug discovery to increasingly incorporate knowledge-based approaches. This evolving paradigm, which has its roots attached to the recent advances in medicinal chemistry, molecular and structural biology, has unprecedentedly demanded the development of up-to-date computational approaches, such as bio- and chemo-informatics. These tools have been pivotal to catalyzing the ever-increasing amount of data generated by the molecular sciences, and to converting the data into insightful guidelines for use in the research pipeline. As a result, ligand- and structure-based drug design have emerged as key pathways to address the pharmaceutical industry’s striking demands for innovation. These approaches depend on a keen integration of experimental and molecular modeling methods to surmount the main challenges faced by drug candidates - in vivo efficacy, pharmacodynamics, metabolism, pharmacokinetics and safety. To that end, the Laboratório de Química Medicinal e Computacional (LQMC of the Universidade de São Paulo has developed forefront research on highly prevalent and life-threatening neglected tropical diseases and cancer. By taking part in global initiatives for pharmaceutical innovation, the laboratory has contributed to the advance of these critical therapeutic areas through the use of cutting-edge strategies in medicinal chemistry.

We investigated the medicinal efficacies of plants used as food in 27 Korean Buddhist temples from 1997 to 2002. We studied 161 species of plants belonging to 135 genera in 65 families. Twenty-one plant parts were utilized as food in 42 different preparations. Approximately 82% of the plants studied had medicinal effects, with a wide range of efficacies (126 types). Of the medicinal plants, 52% were used for digestive problems, circulatory illnesses, and respiratory diseases. These results demonstrate that a high proportion of the food consumed in Korean temples is medicinal, and is used for a wide variety of diseases.

Present review aimed to provide a comprehensive documentation of plants used as anti-rheumatic ethnomedicines in Pakistan and to suggest future recommendations. Data on anti-rheumatic plants was collected from published scientific papers, reports and thesis using online searching engines such as Google Scholar PubMed and Science Direct. Five distinct zones in the country were classified on the basis of geography, humidity and rainfall. We used Sorenson similarity index for plants and their parts used between different zones. A total of 137 anti-rheumatic plant species representing 55 families and 104 genera are used in Pakistan. Herbs (87 plants) were the primary source of anti-rheumatic medicinal plants, while leaves (22 % plant species) were the most frequently used part in the preparation of ethnomedicinal recipes. Highest number of 52 medicinal plant species were found in Zone A having high mountains and cold climate where the prevalence of rheumatism was more common. Solanum surattense was found with highest conservation concerns as it was using in 13 different areas against rheumatism. Results of Sorenson index revealed that there is a similarity of plants and its parts uses between different zones. In conclusions, geography and climate have an important role in causing rheumatic disease. Pakistan has a number of anti-rheumatic plants that are used by the local populations through their traditional knowledge. Moreover, inter zonal similarities among plants and its part uses indicate higher pharmacological potency of these medicinal plants. Further, the review will also provide an insight regarding the conservation status of reported plants. (author)

We provide an extensive summary of the in vitro antibacterial properties of medicinal plants popularly used in Mexico to treat infections, and we discuss the ethnomedical information that has been published for these species. We carried out a bibliographic investigation by analyzing local and international peer-reviewed papers selected by consulting internationally accepted scientific databases from 1995 to 2014. We provide specific information about the evaluated plant parts, the type of extracts, the tested bacterial strains, and the inhibitory concentrations for each one of the species. We recorded the ethnomedical information for the active species, as well as their popular names and local distribution. Information about the plant compounds that has been identified is included in the manuscript. This review also incorporates an extensive summary of the available toxicological reports on the recorded species, as well as the worldwide registries of plant patents used for treating bacterial infections. In addition, we provide a list with the top plant species with antibacterial activities in this review RESULTS: We documented the in vitro antibacterial activities of 343 plant species pertaining to 92 botanical families against 72 bacterial species, focusing particularly on Staphylococcus aureus, Mycobacterium tuberculosis, Escherichia coli and Pseudomonas aeruginosa. The plant families Asteraceae, Fabaceae, Lamiaceae and Euphorbiaceae included the largest number of active species. Information related to popular uses reveals that the majority of the plants, in addition to treating infections, are used to treat other conditions. The distribution of Mexican plants extended from those that were reported to grow in just one state to those that grow in all 32 Mexican states. From 75 plant species, 225 compounds were identified. Out of the total plant species, only 140 (40.57%) had at least one report about their toxic effects. From 1994 to July 2014 a total of 11

Applicability of our computer programs PASS and PharmaExpert to prediction of biological activity spectra of rather complex and structurally diverse phytocomponents of medicinal plants, both separately and in combinations has been evaluated. The web-resource on phytochemicals of 50 medicinal plants used in Ayurveda was created for the study of hidden therapeutic potential of Traditional Indian Medicine (TIM) (http://ayurveda.pharmaexpert.ru). It contains information on 50 medicinal plants, their using in TIM and their pharmacology activities, also as 1906 phytocomponents. PASS training set was updated by addition of information about 946 natural compounds; then the training procedure and validation were performed, to estimate the quality of PASS prediction. It was shown that the difference between the average accuracy of prediction obtained in leave-5%-out cross-validation (94,467%) and in leave-one-out cross-validation (94,605%) is very small. These results showed high predictive ability of the program. Results of biological activity spectra prediction for all phytocomponents included in our database are in good correspondence with the experimental data. Additional kinds of biological activity predicted with high probability provide the information about most promising directions of further studies. The analysis of prediction results of sets of phytocomponents in each of 50 medicinal plants was made by PharmaExpert software. Based on this analysis, we found that the combination of phytocomponents from Passiflora incarnata may exhibit nootropic, anticonvulsant and antidepressant effects. Experiments carried out in mice models confirmed the predicted effects of Passiflora incarnata extracts.

Archaeogenetics in evolutionary medicine.

Archaeogenetics is the study of exploration of ancient DNA (aDNA) of more than 70 years old. It is an important part of the wider studies of many different areas of our past, including animal, plant and pathogen evolution and domestication events. Hereby, we address specifically the impact of research in archaeogenetics in the broader field of evolutionary medicine. Studies on ancient hominid genomes help to understand even modern health patterns. Human genetic microevolution, e.g. related to abilities of post-weaning milk consumption, and specifically genetic adaptation in disease susceptibility, e.g. towards malaria and other infectious diseases, are of the upmost importance in contributions of archeogenetics on the evolutionary understanding of human health and disease. With the increase in both the understanding of modern medical genetics and the ability to deep sequence ancient genetic information, the field of archaeogenetic evolutionary medicine is blossoming.

Full Text Available This study, conducted as part of our overall goal of regular pharmacovigilance of antimalarial medicines, reports on the quality of 132 artemisinin-based antimalarial medicines distributed in Ghana and Togo. Three methods were employed in the quality evaluation—basic (colorimetric tests for establishing the identity of the requisite active pharmaceutical ingredients (APIs, semi-quantitative TLC assay for the identification and estimation of API content, and HPLC assay for a more accurate quantification of API content. From the basic tests, only one sample totally lacked API. The HPLC assay, however, showed that 83.7% of the ACTs and 57.9% of the artemisinin-based monotherapies failed to comply with international pharmacopoeia requirements due to insufficient API content. In most of the ACTs, the artemisinin component was usually the insufficient API. Generally, there was a good correlation between the HPLC and SQ-TLC assays. The overall failure rates for both locally manufactured (77.3% and imported medicines (77.5% were comparable. Similarly the unregistered medicines recorded a slightly higher overall failure rate (84.7% than registered medicines (70.8%. Only two instances of possible cross-border exchange of medicines were observed and there was little difference between the medicine quality of collections from border towns and those from inland parts of both countries.

The use of online teaching tools facilitate the incorporation of self-learning methods. With a view to encouraging convergence in teaching tools and methods in Occupational Legal Medicine, an initiative was set up within the classes of Legal and Forensic Medicine at Saragossa University, as part of the EU funded NetWoRM project, which has been led since 1999 by Ludwig-Maximilians-Universität in Munich (Germany). The interest of medical students in Occupational Legal Medicine has so far been low and in addition different aspects complicate the teaching of Occupational Legal Medicine at medical schools: One reason for the low interest is the limited availability of bedside teaching, one of the students' most favourite and effective way to learn. The reason for that is that most medical schools with occupational departments only have outpatient clinics. "Interesting" patients who be need for educational purposes are therefore only available for a limited part of the day. However, in order to recognize and prevent occupational disorders each medical student and physician needs profound clinical knowledge in Occupational Legal Medicine. This project has proven to be highly efficient in permitting the creation and validation of teaching tools which cover and improve the traditional training of the Occupational Legal Medicine programme imparted in the degree of Medicine.

Medical imaging, including nuclear medicine, is a powerful tool for supporting learning in human morphology and physiology and understanding the nature of disease and response to treatment. The purposes of this study were to create a new case-based learning (CBL) model and to compare CBL and the traditional instructional approach (TIA) in a nuclear medicine clerkship. Internal consistency and expert validity were assessed for the instrument. A quasi-experimental, two-group pretest-posttest design was used for this study. A combination of CBL and the TIA was applied to the experimental group and the TIA only to the control group. Subjects were 70 undergraduate year 5 medical students in a clerkship curriculum. Before and after the educational intervention, students were tested with the instrument. Cronbach's α coefficients of the instrument ranged from 0.79 to 0.95, indicating acceptable to strong internal consistency. For expert validity, the suitability and fitness of the instrument were verified. The overall score was significantly improved for the experimental group (from 3.51 to 3.65, P = .03) but not for the control group (from 3.48 to 3.44, P = .49). The experimental group also showed significantly improved scores in teacher assessment and learning satisfaction, the latter the only domain showing a significant difference of the differences (P = .020). The integration of CBL, allied with the TIA, into clinical clerkships provides medical students with the opportunity to learn a nuclear medicine curriculum in an interactive and case-based format tailored specifically for medical students.

Ethnomedicinal studies are significant for the discovery of new crude drugs from indigenous reported medicinal plants. The current study aimed to report the indigenous medicinal knowledge of plants and herbal remedies used as folk medicines in Cholistan desert, Punjab Province, Pakistan. Rapid appraisal approach (RAA), semi-structured interviews, group meetings with herbalists, landowners and local people having awareness about the medicinal action of plants were employed to collect the data. This study reports 70 medicinal plants belonging to 27 families that were disseminated among 60 different genera and Poaceae was the predominant family over others with 13 reported medicinal plants. Among plant parts, leaves were the dominant over others with 26.4% used in herbal preparations followed by the stem (25.2%), fruit (21.5%), flower (16.3%), seed (6.5%), bark and pod (02%). Haloxylon recurvum exhibited the highest use vale (UV) 0.83 while least UV was exhibited by Mollugo cerviana that was 0.16. Important medicinal plants, reported in this study have been screened for phytochemical and pharmaceutical activities in different parts of the globe. It is recommended that reported medicinal plants having potent action for cancer and hepatitis must be screened for pharmacological activities. Copyright © 2014 Elsevier Ireland Ltd.

The aim of this study was to collect and document information concerning the medicinal plants used by indigenous people and traditional healers in the south of Kerman Province, Iran. Overall, 64 informants between the ages of 30 and 89 were interviewed about the modes of application and consumption of medicinal plants in the region. Quantitative analysis was conducted that included informant consensus factor (ICF), use value (UV), relative frequency of citation (RFC) and cultural importance index (CI). In the current study, a total of 115 medicinal plants in 41 families were reported in the south of the Kerman region. Apiaceae, Asteraceae and Lamiaceae (with 14 species each) were the families with the most medicinal plants. The most frequently used plant parts were leaves at 26.17% and aerial parts (23.49%). Decoction (53%), liniment (23%) and infusion (9%) were the most common preparation methods. The highest UVs were obtained from the following medicinal plants: Amygdalus eburnea Spach, Genista tinctoria L., Calotropis procera (Aiton) Dryand., Fortuynia garcinii (Burm.f.) Shuttlew. and Cerasus mahaleb (L.) Mill. The ICF results indicated that cold-flu and fever were the most common diseases (0.67) in the south of Kerman. Based on the current study, the south of Kerman has many potential medicinal plants, and these plants should be the focus of future research. Copyright © 2017 Elsevier Ireland Ltd.

Reproductive health care, including treatment of early pregnancy failure (EPF) and induced abortion, is an integral part of patient-centered care provided by family physicians, but data suggest that comprehensive training is not widely available to family medicine residents. The purpose of this study was to assess EPF and induced abortion management practices and attitudes of family medicine physician educators throughout the United States and Canada. These data were collected as part of a cross-sectional survey conducted by the Council of Academic Family Medicine Educational Research Alliance that was distributed via E-mail to 3152 practicing physician members of Council of Academic Family Medicine organizations. The vast majority of respondents (88.2%) had treated EPF, whereas few respondents (15.3%) had provided induced medication or aspiration abortions. Of those who had treated EPF, most had offered medication management (72.7%), whereas a minority had provided aspiration management (16.4%). Almost all respondents (95%) agreed that EPF management is within the scope of family medicine, and nearly three-quarters (73.2%) agreed that early induced abortion is within the scope of family medicine. Our findings suggest that family physician educators are more experienced with EPF management than elective abortion. Given the overlap of skills needed for provision of these services, there is the potential to increase the number of family physician faculty members providing induced abortions.

Bulgaria is one of the European countries with the greatest biodiversity, including biodiversity of medicinal plants. The object of this study is Chepan Mountain. It is located in Western Bulgaria and it is part of Balkan Mountain. On the territory of the Chepan Mountain (only 80 km2) we found 344 species of medicinal plants from 237 genera and 83 families. The floristic analysis indicates, that the most of the families and the genera are represented by a small number of inferior taxa. The hemicryptophytes dominate among the life forms with 49.71%. The biological types are represented mainly by perennial herbaceous plants (60.47%). There are 7 types of floristic elements divided in 27 groups. The largest percentage of species are of the European type (58.43%). Among the medicinal plants, there are two Balkan endemic species and 18 relic species. We described 23 species with protection statute. The anthropophytes among the medicinal plants are 220 species (63.95%).

Authoritative knowledge, evidence-based medicine, and behavioral pediatrics.

Kennell, J H

1999-12-01

Evidence-based medicine is the conscientious and judicious use of current best knowledge in making decisions about the care of individual patients, often from well-designed, randomized, controlled trials. Authoritative medicine is the traditional approach to learning and practicing medicine, but no one authority has comprehensive scientific knowledge. Archie Cochrane proposed that every medical specialty should compile a list of all of the randomized, controlled trials within its field to be available for those who wish to know what treatments are effective. This was done first for obstetrics by a group collecting and critically analyzing all of the randomized trials and then indicating procedures every mother should have and those that no mother should have. Support during labor was used as an example. Similar groups are now active in almost all specialties, with information available on the Internet in the Cochrane Database of Systematic Reviews. Developmental-behavioral pediatrics should be part of this movement to evidence-based medicine.

Only the remarkable organisation of Egyptian society, based on an economy of redistribution and allocation of tasks, enabled the erection of the pyramids and the construction of the great temples. Medicine naturally found its place in this organisation as illness was part of the afflictions the pharaoh had to fight against. This particular task was delegated to doctors. The organisation of a medical group could be witnessed on the banks of the Nile almost 5000 years ago and Hesy-Re "the greatest of doctors" (1750 BC), doctor to pharaoh Djoser, is one of the oldest known to mankind. Some doctors were assigned by Egyptian administration to deal with the health problems of communities of workers carrying out the same duties. We consider these doctors to be the pioneers of medicine in the workplace.

This three-part article presents an analysis of the distribution of power and of the nature of the state in Western industrialized societies, and details their implications in medicine. Part I presents a critique of contemporary theories of the Western system of power; discusses the countervailing pluralist and power elite theories, as well as those of bureaucratic and professional control; and concludes with an examination of the Marxist theories of economic determinism, structural determinism, and corporate statism. Part II presents a Marxist theory of the role, nature, and characteristics of state intervention. Part III focuses on the mode of that intervention and the reasons for its growth, with an added analysis of the attributes of state intervention in the health sector and of the dialectical relationship between its growth and the current fiscal crisis of the state. In all three parts, the focus is on Western European countries and on North America, with many examples and categories drawn from the area of medicine.

Women use more medicines than men because they fall ill more often and suffer more from chronic diseases, but also because women pay more attention to their health and have more consciousness and care about themselves. Although medicines can have different effects on women and men, women still represent a small percentage in the first phases of trials (22%) which are essential to verify drugs dosage, side effects, and safety. Even though women are more present in trials, studies results are not presented with a gender approach. This situation is due to educational, social, ethical and economical factors. The scientific research must increase feminine presence in clinical trials in order to be equal and correct, and all the key stakeholder should be involved in this process. We still have a long way to cover and it doesn't concern only women but also children and old people. The aim is to have a medicine not only illness-focused but patient-focused: a medicine able to take into consideration all the patient characteristics and so to produce a really personalized therapy. What above described is part of the reasons why in 2005 was founded the National Observatory for Women's Health (Osservatorio Nazionale sulla Salute della Donna, ONDa) which promotes a gender health awareness and culture in Italy, at all the levels of the civil and scientific society.

Hasan, M.M.; Karim, M.A.; Nahar, N.; Haque, M.M.

2002-01-01

For more than a half a century nuclear medicine is contributing in the field of medicine. Still nuclear medicine is not widely available in many countries. Especially in developing countries due to many a reasons nuclear medicine could not flourish in that way. Availability of radioisotope, high cost of instrument and sophistication of the branch are the three main reasons behind. Even the countries where nuclear medicine is functioning for quite a long time, the facilities for proper function are still not adequate. Training of manpower, maintenance of instruments, regular supply of isotopes and kit and cost effectiveness are some of the major problems. We have seen some fast developments in nuclear medicine in last few decades. Development of gamma detecting systems with SPECT, positron emission detector (PET), supported computer technology and introduction of some newer radiopharmaceuticals for functional studies are few of the examples. The developing countries also have a problem to go on parallel with these rapid development of nuclear medicine in other part of the world. In last few decades we have also witnessed development of CT, MRI, Ultrasound and other imaging modalities as our competitor. Specially for developing countries these have posed as a major challenge for nuclear medicine. A better understanding between developed and developing nations is the key point of todays ultimate success in any sector. For real development of nuclear medicine and to give the majority of the people the benefit of nuclear medicine a better and more active co-operation is needed between all the countries. The paper presents the difficulties and some practical problems of practicing nuclear medicine in a developing country. And also appeals for global co-operation to solve the problems for better interest of the subject

Training the next generation of providers in addiction medicine.

Rasyidi, Ernest; Wilkins, Jeffery N; Danovitch, Itai

2012-06-01

Within the United States there exists a profound discrepancy between the significant public health problem of substance abuse and the access to treatment for addicted individuals. Part of the insufficient access to treatment is a function of relatively low levels or professional experts in addiction medicine. Part of the low levels of professional addiction experts is the result of inadequate addiction medicine training of medical students and residents. This article outlines deficits in addiction medicine training among medical students and residents, yet real change in the addiction medicine training process will always be subject to the complexity of producing alterations across multiple credentialing institutions as well as the keen competition between educators for “more time” for their particular subject. Other hurdles include the broad-based issue of stigma regarding alcoholism and other substance abuse that likely impact all systems that regulate physician addiction medicine training. As noted in the discussion of psychiatry residency, even psychiatry residents manifest stigma regarding substance abusing patients. Five currently active processes may allow for fundamental change to the inertia in physician addiction medicine training while also potentially impacting stigma: 1. We appear to be at the beginning of the integration of addiction into traditional medicine through the formation of a legitimized addiction medicine subspecialty. 2. The training of primary care trainees and practitioners in the use of SBIRT is accelerating, thus creating another process of addiction integration into traditional medicine. 3. The PCMH is being established as a model for primary care 4. The Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) became effective for group health care plan years beginning on or after July 1, 2010; thereby, substance abuse benefits and cost are to be the same as general medical or surgical

Before the new round of healthcare reform in China, primary healthcare providers could obtain a fixed 15 % or greater mark-up of profits by prescribing and selling medicines. There were concerns that this perverse incentive was a key cause of irrational medicine use. China's new Essential Medicines Program (EMP) was launched in 2009 as part of the national health sector reform initiatives. One of its core policies was to eliminate primary care providers' economic incentives to overprescribe or prescribe unnecessarily expensive drugs, which were regarded as consequences of China's traditional financing system for health institutions. The objective of the study was to measure changes in prescribing patterns in primary healthcare facilities after the removal of the economic incentives for physicians to overprescribe as a result of the implementation of the EMP. A comparison design was applied to 8,258 prescriptions in 2007 and 8,278 prescriptions in 2010, from 83 primary healthcare facilities nationwide. Indicators were adopted to evaluate medicine utilization, which included overall number of medicines, average number of Western and traditional Chinese medicines, pharmaceutical expenditure per outpatient prescription, and proportion of prescriptions that contained two or more antibiotics. We further assessed the use of medicines (antibiotics, infusion, hormones, and intravenous injection) per disease-specific prescription for hypertension, diabetes, coronary artery heart disease, bronchitis, upper respiratory tract infection, and gastritis. A difference-in-difference analysis was employed to evaluate the net policy effect. Overall changes in indicators were not found to be statistically significant between the 2 years. The results varied for different diseases. The number of Western drugs per outpatient prescription decreased while that of traditional Chinese medicines increased. Overuse of antibiotics remained an extensive problem in the treatment of many diseases

Confronting zoonoses through closer collaboration between medicine and veterinary medicine (as 'one medicine').

In the 19th century, the concept of 'one medicine' was embraced by leaders in the medical and veterinary medical communities. In the 20th century, collaborative efforts between medicine and veterinary medicine diminished considerably. While there have been some notable exceptions, such as Calvin W. Schwabe's proposal for unifying human and veterinary medicine and joint efforts by the Food and Agriculture Organization and World Health Organization to control zoonotic diseases, 'one medicine' has languished in the modern milieu of clinical care, public health, and biomedical research. Risks of zoonotic disease transmission are rarely discussed in clinical care which is of particular concern if humans and/or animals are immunosuppressed. Physicians and veterinarians should advise their patients and pet-owning clients that some animals should not be pets. The risk of zoonotic disease acquisition can be considerable in the occupational setting. Collaborative efforts in biomedical research could do much to improve human and animal health. As the threat of zoonotic diseases continues to increase in the 21st century, medicine and veterinary medicine must revive 'one medicine' in order to adequately address these challenges. 'One medicine' revival strategies must involve medical and veterinary medical education, clinical care, public health and biomedical research.

Compartment modelling in nuclear medicine: a new program for the determination of transfer coefficients

International Nuclear Information System (INIS)

Hallstadius, L.

1986-01-01

In many investigations concerning transport/exchange of matter in a natural system, e.g. functional studies in nuclear medicine, it is advantageous to relate experimental results to a model of the system. A new computer program is presented for the determination of linear transfer coefficients in a compartment model from experimentally observed time-compartment content curves. The program performs a least-square fit with the specified precision of the observed values as weight factors. The resulting uncertainty in the calculated transfer coefficients may also be assessed. The application of the program in nuclear medicine is demonstrated and discussed. (author)

To determine the level and sources of medical student debt at the Christchurch School of Medicine. A questionnaire, The New Zealand Wellbeing, Intentions, Debt, and Experiences (WIDE) Survey of Medical Students, was developed and administered to all 204 medical students at the Christchurch School of Medicine and Health Sciences. Included were questions on student demographics, sources and levels of debt, parental financial support, and student perceptions of their debt. The response rate was 88%. International students, whose debt was with an overseas government, and students with mortgages were excluded from the data analysis. The combined total debt for the remaining 165 students was $7775000 with $6290000 (81%) owed to the Government Students Loans scheme. One quarter of 6th year medical students had a debt over $83250, 50% had a debt over $70000, and 75% had a debt over $50000. Student allowances were inaccessible to 64% of 4th and 5th year students and part-time employment during term-time was common. Lack of funds was reported to impair full participation in the medical course. The majority of medical students at the Christchurch School of Medicine accumulate high levels of debt, mainly dtrough the Government Student Loans scheme, during their medical training.

Ophiocordyceps sinensis is a valuable traditional Chinese medicine with a high market price. In this study, a polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) method based on 2 enzymes was developed to distinguish O. sinensis from 6 common counterfeit species. To verify the applicability of this method, we experimentally tested O. sinensis organisms, tablet preparations made from O. sinensis, and cultured mycelia isolated from O. sinensis. To validate the results from this PCR-RFLP method, all real samples were identified by internal transcribed spacer sequencing. This is, to our knowledge, the first time the PCR-RFLP method has been applied to identify O. sinensis. The selection of 2 restrictive enzymes for identification dramatically improved the accuracy and efficiency of this method. It is the great advantage of this method that sampling from either of 2 parts of O. sinensis-the fruiting body or the caterpillar body-would not cause any difference in the final experimental results. Therefore, this method is not only feasible for testing crude drugs of O. sinensis but it is also useful when the crude drugs are broken down into powder or made into tablets, demonstrating the promising prospect of application in quality control.

The paper deals with the development of the first editions of the Austrian Pharmacopoeia, Pharmacopoea Austriaca, since its origin in the year 1812. It demonstrates its gradual retardation in the period when nearly all medicinal substances had to be prepared only in pharmacies. The conception was changed as late as 1855 in the Fifth Edition, when it was allowed to buy many medicinal substances from producers or wholesalers. At the same time, requirements for organoleptic properties and chemical purity began to be introduced. The present communication also deals with the chemical drugs used in the mid-19th century and is based on a comparison of the pharmacopoeias of 1836 and 1855. It presents some typical examples, such as alkaloids and metal compounds.

Full Text Available Natural products and traditional medicines are of great importance. Such forms of medicine as traditional Chinese medicine, Ayurveda, Kampo, traditional Korean medicine, and Unani have been practiced in some areas of the world and have blossomed into orderly-regulated systems of medicine. This study aims to review the literature on the relationship among natural products, traditional medicines, and modern medicine, and to explore the possible concepts and methodologies from natural products and traditional medicines to further develop drug discovery. The unique characteristics of theory, application, current role or status, and modern research of eight kinds of traditional medicine systems are summarized in this study. Although only a tiny fraction of the existing plant species have been scientifically researched for bioactivities since 1805, when the first pharmacologically-active compound morphine was isolated from opium, natural products and traditional medicines have already made fruitful contributions for modern medicine. When used to develop new drugs, natural products and traditional medicines have their incomparable advantages, such as abundant clinical experiences, and their unique diversity of chemical structures and biological activities.

Prior to 1976, the Radiation Medicine Centre had conducted 12 short courses of five weeks' duration on medical uses of radioisotopes. A total of 162 medical and scientific personnel attended the courses from various parts of India. Owing to the rapid advances made in nuclear medicine these courses were becoming inadequate, and in 1973 the Centre introduced one-year full time training courses for doctors and science graduates, peparing them for examinations for the Diploma in Radiation Medicine (DRM) and the Diploma in Medical Radioisotope Techniques (DMRIT) of the University of Bombay. By March 1984, 64 doctors and 53 technologists had obtained the DRM and DMRIT. A recent survey indicated that 70% of the DRM physicians and 68% of the DMRIT technologists are employed in nuclear medicine departments. Besides the formal one-year training courses, the Centre has conducted advanced courses of two weeks' duration on scintigraphy and thyroid function tests. The Radiation Medicine Centre has been the regional reference centre in nuclear medicine for the World Health Organization and International Atomic Energy Agency for more than ten years. The Centre has trained sponsored personnel from other countries of the region. The Centre has also organized seven symposia, workshops and seminars, four of them in collaboration with WHO and one with the IAEA. (author)

[Motivation for the choice of complementary and mainstream medicine. Patients' behavior in a pluralistic medical system].

Schär, A; Messerli-Rohrbach, V

1999-02-01

The reasons for choosing between various therapeutic possibilities depend in part on rational and in part on emotional factors. This project dealt with the systematic verification of some decision factors most of which were known already. The project was divided in a qualitative and a quantitative part. The qualitative segment was based on semistructured interviews with patients of general practitioners or of naturopaths. This procedure is often used in ethnological research. It identified and evaluated the main motives for the individual choices of therapies by the patients. The quantitative part of the study was carried out by a procedure often used in social sciences, namely by strictly structured telephone interviews of several thousand policyholders of the health insurance fund Helvetia. The aim of this part of the study was to verify the findings of the qualitative study and to investigate the possible significance of additional sociological factors for the choice between different therapies. The conclusions drawn from the abundance of data show that a widespread use of complementary medicine is a reality. Both parts of the project came to the same conclusions. The patients use complementary medicine in a very pragmatic way, be it alternately, be it in parallel but not necessarily in addition to mainstream medicine. The behavior of the patients is very complex, depends on many factors, and can neither be predicted nor easily influenced, not even by an additional free insurance for complementary medicine which was offered to one of the subgroups of the study (in conjunction with J. Sommer's project 'A Randomized Experiment Studying the Effect of Including Complementary Medicine in the Mandatory Benefit Package of Health Insurance Funds in Switzerland'). The interpretation of the telephone interviews concerning the significance of some of the registered sociological factors turned out to be difficult. The project aimed primarily at illustrating the use of

Martin, P.M.

1977-01-01

Numerical description of medical and biologic phenomena is proliferating. Laboratory studies on patients now yield measurements of at least a dozen indices, each with its own normal limits. Within nuclear medicine, numerical analysis as well as numerical measurement and the use of computers are becoming more common. While the digital computer has proved to be a valuable tool for measurment and analysis of imaging and radioimmunoassay data, it has created more work in that users now ask for more detailed calculations and for indices that measure the reliability of quantified observations. The following material is presented with the intention of providing a straight-forward methodology to determine values for some useful parameters and to estimate the errors involved. The process used is that of asking relevant questions and then providing answers by illustrations. It is hoped that this will help the reader avoid an error of the third kind, that is, the error of statistical misrepresentation or inadvertent deception. This occurs most frequently in cases where the right answer is found to the wrong question. The purposes of this chapter are: (1) to provide some relevant statistical theory, using a terminology suitable for the nuclear medicine field; (2) to demonstrate the application of a number of statistical methods to the kinds of data commonly encountered in nuclear medicine; (3) to provide a framework to assist the experimenter in choosing the method and the questions most suitable for the experiment at hand; and (4) to present a simple approach for a quantitative quality control program for scintillation cameras and other radiation detectors

2001-01-01

Education in Nuclear Physics, Medical Physics and Radiation Protection in medicine and veterinary medicine studies on Belgrade University is an integral part of the curriculum, incorporated in different courses of graduate and post-graduate studies. During graduate studies students get basic elements of Nuclear Physics through Physics and/or Biophysics courses in the 1 st year, while basic knowledge in Medical Physics and Radiation Protection is implemented in the courses of Radiology, Physical Therapy, Radiation Hygiene, Diagnostic Radiology and Radiation Therapy in the 4 th or 5 th year. Postgraduate studies offer MSc degree in Radiology, Physical Therapy, while courses in Nuclear Physics, Nuclear Instrumentation, Radiation Protection and Radiology are core or optional. On the Faculty of Veterinary Medicine graduated students may continue their professional education and obtain specialization degree in Radiology, Physical Therapy or Radiation Protection. On the Faculty of Medicine there are specialization degrees in Medical Nuclear Physics. Still, a closer analysis reveals a number of problems both from methodological and cognitive point of view. They are related mostly to graduate students ability to apply their knowledge in practise and with the qualifications of the educators, as those engaged in graduate studies lack basic knowledge in biological and medical sciences, while those engaged in post graduate studies mostly lack basic education in physics. Therefore, a reformed curricula resulting from much closer collaboration among educators, universities and professional societies at the national level should be considered. (author)

An ethnobotanical survey was completed in a remote village and surrounding country of Xinjiang, where most Uyghur medicinal plants could be collected. This work clarifies and increases ethnobotanical data. We surveyed and organized aromatic medicinal plants that are commonly used in clinical settings to provide a significant reference for studying new medical activities. In the survey, informants who have traditional knowledge on aromatic Uyghur medicinal plants were interviewed between March 2014 and September 2014. Aromatic medicinal plant species and pertinent information were collected. Some therapeutic methods and modes of preparation of traditional aromatic medicinal plants were found. A total of 86 aromatic medicinal plant species belonging to 36 families were included in our study. We identified 34 plant species introduced from different regions such as Europe, India and Mediterranean areas. Fruits and whole plants were the most commonly used parts of plant, and most aromatic medicinal plants could be applied as medicine and food. We assigned the medicinal plants a use value (UV). Knowing the UV of species is useful in determining the use reliability and pharmacological features of related plants. Xinjiang is an area in which indigenous aromatic medicinal plants are diversely used and has therefore established a sound dimensional medical healthcare treatment system. Some aromatic Uyghur medicinal plants are on the verge of extinction. Hence, further strategies for the conservation of these aromatic medicinal plants should be prioritized.

Oral medicine (stomatology) is a recognized and increasingly important dental specialty in many parts of the world that recognizes and fosters the interplay between medical health and oral health. Its dental activities rely greatly on the underlying biology of disease and evidence-based outcomes. However, full recognition of the importance of oral medicine to patient care, research, and education is not yet totally universally acknowledged. To address these shortcomings, we outline the birth, growth, and future of oral medicine globally, and record identifiable past contributions to the development of the specialty, providing an accurate, unique, and valuable resource on oral medicine. Although it was challenging to gather the data, we present this information as a review that endeavors to summarize the salient points about oral medicine, based on MEDLINE, other internet searches, communication with oral medicine and stomatological societies across the world, the web page http://en.wikipedia.org/wiki/List_of_dental_organizations, and discussions with a wide range of key senior persons in the specialty.

The Dosage Form of Aragh in Treatment, from the Iranian Traditional Medicine Perspective.

Science.gov (United States)

Adl, Mehdi; Emtiazi, Majid

2016-05-01

The Iranian traditional medicine is one of the branches of complementary medicine and it is based on using the dosage forms of plants. One of the most common forms of pharmaceutical plants is Aragh. Due to ease-of-use, distillate is a more acceptable form among the public. In this article, it is attempted to study the usage forms and effects of Aragh according to the valid traditional medicine resources. This article is a review of Iranian traditional medicine textbooks such as Makhzan-ul-dawiah, Gharabadin Kabir, Cannon of Medicine, and other recent texts on medical plants. According to the traditional medicine, the process of getting Aragh is a kind of distillation, which is performed by using Ghar and Alembic (the equipment that are used in distillation). Distillation is the process of extracting and refining the fluid of a plant. Aragh of the plants is much more effective on the body than the plant itself. Traditional medicine regards Aragh as a new kind of drug (medicine) that is rarely mentioned in older texts (except for golab). However, the modern medicine regards it as a dosage form of essence, which is dissolved in water. The more the essence, the better the distillate gets. According to the traditional medicine sources, since the time of Hakim Aghil Khorasani, Aragh was used more and more every day. About 100 kinds of Araghs are mentioned in ancient texts, which are extracted from simple plants. Considering the distillation process and the way it performs, and by knowing that Aragh is a plant's softest and the most influential entity, it seems that it has a huge effect on Arvah and Ghova, the main parts like heart and brain and nervous parts.

[The teaching and application of alternative medicine in medical education programs].

Science.gov (United States)

Chiang, Han-Sun

2014-12-01

The history of alternative medicine is perhaps as long as the history of human medicine. The development of evidence-based medicine has not annihilated alternative medicine. On the contrary, more people turn to alternative medicine because this approach to treatment serves as an effective remedial or supportive treatment when used in conjunction with evidence-based medicine. In contemporary healthcare, alternative medicine is now an essential part of integrated medicine. In Taiwan, most professional medical practitioners have not received proper education about alternative medicine and therefore generally lack comprehensive knowledge on this subject. While alternative medicine may be effective when used with some patients, it may also impart a placebo effect, which helps restore the body and soul of the patients. Medical staff with advanced knowledge of alternative medicine may not only help patients but also improve the doctor-patient relationship. There is great diversity in alternative medicine, with some alternative therapies supported by evidence and covered by insurance. However, there also remain fraudulent medical practices that may be harmful to health. Medical staff must be properly educated so that they can provide patients and their family a proper understanding and attitude toward alternative medicine. Therefore, alternative medicine should be included in the standard medical education curriculum. Offering classes on alternative medicine in university for more than 10 years, the author shares his experiences regarding potential content, lecture subjects, group experience exercises, and in-class activities. This article is intended to provide a reference to professors in university medical education and offer a possible model for alternative medicine education in Taiwan.

Incommensurable Worldviews? Is Public Use of Complementary and Alternative Medicines Incompatible with Support for Science and Conventional Medicine?

Science.gov (United States)

Stoneman, Paul; Sturgis, Patrick; Allum, Nick; Sibley, Elissa

2013-01-01

Proponents of controversial Complementary and Alternative Medicines, such as homeopathy, argue that these treatments can be used with great effect in addition to, and sometimes instead of, ‘conventional’ medicine. In doing so, they accept the idea that the scientific approach to the evaluation of treatment does not undermine use of and support for some of the more controversial CAM treatments. For those adhering to the scientific canon, however, such efficacy claims lack the requisite evidential basis from randomised controlled trials. It is not clear, however, whether such opposition characterises the views of the general public. In this paper we use data from the 2009 Wellcome Monitor survey to investigate public use of and beliefs about the efficacy of a prominent and controversial CAM within the United Kingdom, homeopathy. We proceed by using Latent Class Analysis to assess whether it is possible to identify a sub-group of the population who are at ease in combining support for science and conventional medicine with use of CAM treatments, and belief in the efficacy of homeopathy. Our results suggest that over 40% of the British public maintain positive evaluations of both homeopathy and conventional medicine simultaneously. Explanatory analyses reveal that simultaneous support for a controversial CAM treatment and conventional medicine is, in part, explained by a lack of scientific knowledge as well as concerns about the regulation of medical research.

The Asian School of Nuclear Medicine (ASNM) was formed in February 2003, with the ARCCNM as the parent body. Aims of ASNM: 1. To foster Education in Nuclear Medicine among the Asian countries, particularly the less developed ones. 2. To promote training of Nuclear Medicine Physicians in cooperation with government agencies, IAEA and universities and societies. 3. To assist in national and regional training courses, award continuing medical education (CME) points and provide regional experts for advanced educational programmes. 4. To work towards awarding of diplomas or degrees in association with recognized universities by distance learning and practical attachments, with examinations. The ASNM works toward a formal training courses leading to the award of a certificate in the long term. The most fundamental job of the ASNM remains the transfer of knowledge from the more developed countries to the less developed ones in the Asian region. The ASNM could award credit hours to the participants of training courses conducted in the various countries and conduct electronic courses and examinations. CME programmes may also be conducted as part of the regular ARCCNM meetings and the ASNM will award CME credit points for such activities

Poor representation of Blacks, Latinos, and Native Americans in medicine.

Science.gov (United States)

Rodriguez, José E; Campbell, Kendall M; Adelson, Wendi J

2015-04-01

In this article, the authors discuss how various systems in medicine are limiting representation of blacks, Latinos, and Native Americans. Flat and decreasing percentages of Underrepresented Minorities in Medicine (URMM), especially in the black and Native American populations, is concerning for family medicine since members from URMM groups care for minority and underserved populations in greater numbers. Underrepresentation is not only noted in the medical community but also in our medical schools when it comes to numbers of URMM faculty. The changing definition of "disadvantaged" in medical school admissions has also played a part in limiting URMM representation. In addition, the Medical College Admissions Test (MCAT) excludes black, Latino, and Native American students in greater numbers. The authors support these arguments with evidence from the medical literature. Although unintentional, these systems effectively limit representation of blacks, Latinos, and Native Americans in medicine. Effective changes are suggested and can be implemented to ensure that URMM individuals have equal representation in careers in medicine.

Narrative Based Medicine (NBM) can be defined as follows; a) It views the patient's illness as an unfolding story within the wider story of the patient's life and life-world; b) It acknowledges the patient as the narrator of the story and the subject of the tale; c) It recognizes that all medical theories, hypothesis and pathophysiologies as socially constructed narratives and accepts the coexistence of multiple different narratives; d) It regards the emergence of new stories from dialogue and discourse between patients and healthcare professionals as part of the treatment. Because psychiatry is the only area of specialist medicine where talking and listening are explicitly understood to be therapeutic, NBM can be adopted an effective perspective and method in psychiatry.

First, the traditional textbooks were reviewed to generate a list of animal products described as ingredients. Second, animal parts that are currently used in Bhutan were identified. Third, the ethnopharmacological uses of each animal ingredients were translated into English medical terminologies by consulting Traditional Physicians, clinical assistants, pharmacognosists, and pharmacists in Bhutan. Fourth, the animal parts were taxonomically identified and their Latin names were confirmed by crosschecking them with online animal databases and relevant scientific literature. The study found 73 natural products belonging to 29 categories derived from 45 medicinal animals (36 vertebrates and 9 invertebrates), comprising of 9 taxonomic categories and 30 zoological families. Out of 116 formulations currently produced, 87 of them contain one or more extracts and products obtained from 13 medicinal animals to treat more than 124 traditionally classified illnesses. Only five animal ingredients were found available in Bhutan and rest of the animal parts are being imported from India. Out of 73 natural products described in the traditional textbooks, only 13 of them (some omitted and few substituted by plants) are currently included in 87 formulations of BSM.

Multiple complex factors contribute to the slow pace of women's advancement into leadership positions in academic medicine. In this article, the authors propose that stereotype threat--under which individuals who are members of a group characterized by negative stereotypes in a particular domain perform below their actual abilities in that domain when group membership is emphasized--may play an important role in the underrepresentation of women in leadership positions in academic medicine. Research to objectively assess the impact of stereotype threat for women in academic medicine is feasible and necessary to confirm this hypothesis. Still, a number of conditions present in the academic medicine community today have been shown to trigger stereotype threat in other settings, and stereotype threat fits with existing research on gender in academic medicine. In the meantime, academic health centers should implement relatively simple measures supported by experimental evidence from other settings to reduce the risk of stereotype threat, including (1) introducing the concept of stereotype threat to the academic medicine community, (2) engaging all stakeholders, male and female, to promote identity safety by enacting and making faculty aware of policies to monitor potential instances of discrimination, and training faculty to provide performance feedback that is free of gender bias, (3) counteracting the effects of sex segregation at academic health centers by increasing exposure to successful female leaders, (4) reducing gender stereotype priming by avoiding stereotypically male criteria for promotion, grants, and awards, and (5) building leadership efficacy among female physicians and scientists.

Gastrointestinal disorders cause morbidity and can lead to mortality, especially in the developing world where sanitation is deficient. A large part of the human population relies on medicinal plants for treating various diseases, including gastrointestinal disorders. The present review summarizes the traditional uses of medicinal plants of Nepal used to treat gastrointestinal disorders, and evaluates their bio-efficacy based on a review of the available phytochemical and pharmacological literature. We searched different electronic databases and libraries for the literature on medicinal plants used in Nepal to treat gastrointestinal disorders. For each species, we also searched the literature for information on conservation status, as well as for phytochemical and pharmacological studies in support of the ethnobotanical information. We used principal component analysis to explore the relation among disorders and plant families, plant life forms, plant parts and preparation modes. We also performed permutation tests to determine if botanical families were used more often than expected considering their availability in the Nepali flora. We documented a total of 947 species belonging to 158 families and 586 genera used to treat gastrointestinal disorders in Nepal. Diarrhea was the disorder treated by the highest number of species (348), followed by stomachache (340) and dysentery (307). Among the reported species, five were endemic to Nepal, whereas 16 orchid species were protected under CITES Appendices II and III. The randomization test showed that species belonging to 14 families were used less often than expected, whereas plants belonging to 25 families were used more often than expected. The PCA scatter plot showed distinct groups of gastrointestinal disorders treated with similar plant life forms, plant parts, and/or preparation modes. We found 763 phytochemical studies on 324 species and 654 pharmacological studies on 269 species. We showed the diversity and

Pharmacologically active constituents from traditional medicinal plants have received great attention as sources of novel agents, pharmaceutical intermediates, and chemical entities for synthetic or semisynthetic drugs due to their potent pharmacological activities, low toxicity, and economic viability. Numerous components have been isolated from traditional medicinal plants, including alkaloids, flavonoids, and terpenoids, and clinical and experimental studies suggested that these components have useful pharmacological properties such as antiinfectious, antioxidative, and antiinflammatory effects. In this review, modern ethnobotanical approaches to explore folk medicinal plants as candidates for drug discovery with the greatest possibility of success are discussed. Determining the bioactive mechanisms and tracing structure-activity relationships will promote the discovery of new drugs and pharmacological agents.

[New horizons in medicine. The application of "fuzzy logic" in clinical and experimental medicine].

Science.gov (United States)

Guarini, G

1994-06-01

In medicine, the study of physiological and physiopathological problems is generally programmed by elaborating models which respond to the principals of formal logic. This gives the advantage of favouring the transformation of the formal model into a mathematical model of reference which responds to the principles of the set theories. All this is in the utopian wish to obtain as a result of each research, a net answer whether positive or negative, according to the Aristotelian principal of tertium non datur. Taking this into consideration, the A. briefly traces the principles of modal logic and, in particular, those of fuzzy logic, proposing that the latter substitute the actual definition of "logic with more truth values", with that perhaps more pertinent of "logic of conditioned possibilities". After a brief synthesis on the state of the art on the application of fuzzy logic, the A. reports an example of graphic expression of fuzzy logic by demonstrating how the basic glycemic data (expressed by the vectors magnitude) revealed in a sample of healthy individuals, constituted on the whole an unbroken continuous stream of set partials. The A. calls attention to fuzzy logic as a useful instrument to elaborate in a new way the analysis of scenario qualified to acquire the necessary information to single out the critical points which characterize the potential development of any biological phenomenon.

In this paper, the popular domestic varieties and quality standard of Scrophulariaceae plants used in Tibetan medicine were analyzed. The results showed that there were 11 genera and 99 species (including varieties), as well as 28 medicinal materials varieties of Scrophulariaceae plants were recorded in the relevant literatures. In relevant Tibetan standards arid literatures, there are great differences in varieties, sources, parts, and efficacies of medicinal plant. Among them, about 41.4% (including 41 species) of endemic plants, about 15.2% (including 15 species) of the original plants have medicinal standard legal records, except the medicinal materials of Scrophalaria ningpoensis, Lagotis brevituba, Picrorhiza scrophulariiflora, Veronica eriogyne general, most varieties have not completed quality standard. Consequently it is necessary to reinforce the herbal textual, resources and the use present situation investigation, the effects of the species resources material foundation and biological activity, quality standard, specification the medical terms of the plants, and promote Tibetan medicinal vareties-terminologies-sources such as the criterion and quality standard system for enriching the varieties of Tibetan medicinal materials and Chinese medicinal resources.

Material and Method: A total of 170 family physicians working in Kahramanmaras were included in the study. After obtaining informed consent a questionnaire comprising questions regarding socio-demographic properties, conveying contracted family physicians as family medicine specialists and organization of the training program was applied to participants. Results: Among physicians participating in the study 130 (76.5% were male and 40 (23.5% were female, with a mean age of 40.7±7.1 (min = 26 years, max = 64 years. The mean duration of professional experience of physicians was 15.3±7.0 (min = 2 years, max = 40 years years. Of all, 91 (53.5% participants had already read the decree on family medicine specialist training program for contracted family physicians. A hundred and fifteen (67.6% family physicians supported that Family Medicine Specialty program should be taken part-time without interrupting routine medical tasks. Only 51 (30.0% participants stated the requirement of an entrance examination (TUS for family medicine specialty training. Conclusion: Family medicine specialty training program towards family physicians should be considered in the light of scientific criteria. In family medicine, an area exhibited a holistic approach to the patient; specialty training should be through residency training instead of an education program. For this purpose, family medicine departments in medical faculties should play an active role in this process. Additionally further rotations in needed branches should be implemented with a revision of area should be performed. In medicine practical training is of high importance and distant or part-time education is not appropriate, and specialist training shall be planned in accordance with the medical specialty training regulations.

Elasto-dynamic analysis of a gear pump-Part III: Experimental validation procedure and model extension to helical gears

Science.gov (United States)

Mucchi, E.; Dalpiaz, G.

2015-01-01

This work concerns external gear pumps for automotive applications, which operate at high speed and low pressure. In previous works of the authors (Part I and II, [1,2]), a non-linear lumped-parameter kineto-elastodynamic model for the prediction of the dynamic behaviour of external gear pumps was presented. It takes into account the most important phenomena involved in the operation of this kind of machine. The two main sources of noise and vibration are considered: pressure pulsation and gear meshing. The model has been used in order to foresee the influence of working conditions and design modifications on vibration generation. The model's experimental validation is a difficult task. Thus, Part III proposes a novel methodology for the validation carried out by the comparison of simulations and experimental results concerning forces and moments: it deals with the external and inertial components acting on the gears, estimated by the model, and the reactions and inertial components on the pump casing and the test plate, obtained by measurements. The validation is carried out comparing the level of the time synchronous average in the time domain and the waterfall maps in the frequency domain, with particular attention to identify system resonances. The validation results are satisfactory globally, but discrepancies are still present. Moreover, the assessed model has been properly modified for the application to a new virtual pump prototype with helical gears in order to foresee gear accelerations and dynamic forces. Part IV is focused on improvements in the modelling and analysis of the phenomena bound to the pressure evolution around the gears in order to achieve results closer to the measured values. As a matter of fact, the simulation results have shown that a variable meshing stiffness has a notable contribution on the dynamic behaviour of the pump but this is not as important as the pressure phenomena. As a consequence, the original model was modified with the

Technical protocol for laboratory tests of transformation of veterinary medicinal products and biocides in liquid manures. Version 1.0

Energy Technology Data Exchange (ETDEWEB)

Kreuzig, Robert [Technische Univ. Braunschweig (Germany). Inst. fuer Oekologische Chemie und Abfallanalytik

2010-07-15

The technical protocol under consideration describes a laboratory test method to evaluate the transformation of chemicals in liquid bovine and pig manures under anaerobic conditions and primarily is designed for veterinary medicinal products and biocides. The environmentally relevant entry routes into liquid manures occur via urine and feces of cattle and pigs in stable housings after excretion of veterinary medicinal products as parent compounds or metabolites and after the application of biocides in animal housings. Further entry routes such as solid dung application and direct dung pat deposition by production animals on pasture are not considered by this technical protocol. Thus, this technical protocol focused on the sampling of excrements from cattles and pigs kept in stables and fed under standard nutrition conditions. This approach additionally ensures that excrement samples are operationally free of any contamination by veterinary medicinal products and biocides. After the matrix characterization, reference-manure samples are prepared from the excrement samples by adding tap water to adjust defined dry substance contents typical for bovine or pig manures. This technical protocol comprehends a tiered experimental design in two parts: (a) Sampling of excrements and preparation of reference bovine and pig manures; (b) Testing of anaerobic transformation of chemicals in reference manures.

The purpose of this article is to highlight medical education research studies published in 2008 that were methodologically superior and whose outcomes were pertinent to teaching and education in emergency medicine. Through a PubMed search of the English language literature in 2008, 30 medical education research studies were independently identified as hypothesis-testing investigations and measurements of educational interventions. Six reviewers independently rated and scored all articles based on eight anchors, four of which related to methodologic criteria. Articles were ranked according to their total rating score. A ranking agreement among the reviewers of 83% was established a priori as a minimum for highlighting articles in this review. Five medical education research studies met the a priori criteria for inclusion and are reviewed and summarized here. Four of these employed experimental or quasi-experimental methodology. Although technology was not a component of the structured literature search employed to identify the candidate articles for this review, 14 of the articles identified, including four of the five highlighted articles, employed or studied technology as a focus of the educational research. Overall, 36% of the reviewed studies were supported by funding; three of the highlighted articles were funded studies. This review highlights quality medical education research studies published in 2008, with outcomes of relevance to teaching and education in emergency medicine. It focuses on research methodology, notes current trends in the use of technology for learning in emergency medicine, and suggests future avenues for continued rigorous study in education.

Recognizing fundamental flaws in the fragmented US health care systems and the potential of an integrative, generalist approach, the leadership of 7 national family medicine organizations initiated the Future of Family Medicine (FFM) project in 2002. The goal of the project was to develop a strategy to transform and renew the discipline of family medicine to meet the needs of patients in a changing health care environment. A national research study was conducted by independent research firms. Interviews and focus groups identified key issues for diverse constituencies, including patients, payers, residents, students, family physicians, and other clinicians. Subsequently, interviews were conducted with nationally representative samples of 9 key constituencies. Based in part on these data, 5 task forces addressed key issues to meet the project goal. A Project Leadership Committee synthesized the task force reports into the report presented here. The project identified core values, a New Model of practice, and a process for development, research, education, partnership, and change with great potential to transform the ability of family medicine to improve the health and health care of the nation. The proposed New Model of practice has the following characteristics: a patient-centered team approach; elimination of barriers to access; advanced information systems, including an electronic health record; redesigned, more functional offices; a focus on quality and outcomes; and enhanced practice finance. A unified communications strategy will be developed to promote the New Model of family medicine to multiple audiences. The study concluded that the discipline needs to oversee the training of family physicians who are committed to excellence, steeped in the core values of the discipline, competent to provide family medicine's basket of services within the New Model, and capable of adapting to varying patient needs and changing care technologies.

2011-06-01

With the development of the knowledge economy, knowledge has become one of the most important resources for social progress and economic development. Some countries have proposed measures for the protection of their own traditional knowledge. Traditional Chinese medicine belongs to the category of intangible cultural heritage because it is an important part of Chinese cultural heritage. Today the value of traditional knowledge of Chinese medicine has been widely recognized by the domestic and international public. This paper discusses the definition of traditional knowledge of Chinese medicine and its protection, and evaluates research on its classification. We review the present status of the protection of traditional knowledge of Chinese medicine and tentatively put forward some possible ideas and methods for the protection of traditional knowledge of Chinese medicine. Our goal is to find a way to strengthen the vitality of traditional Chinese medicine and consolidate its foundation. We believe that if we could establish a suitable sui generis(sui generis is a Latin term meaning "of its own kind" and is often used in discussions about protecting the rights of indigenous peoples. Here we use it to emphasize the fact that protection of traditional knowledge of Chinese medicine cannot be achieved through existing legal means of protection alone due to its unique characteristics) system for traditional knowledge, a more favorable environment for the preservation and development of traditional Chinese medicine will ultimately be created.

Role of laboratory medicine in collaborative healthcare.

Watson, Ian D; Wilkie, Patricia; Hannan, Amir; Beastall, Graham H

2018-04-09

Healthcare delivery and responsibility is changing. Patient-centered care is gaining international acceptance with the patient taking greater responsibility for his/her health and sharing decision making for the diagnosis and management of illness. Laboratory medicine must embrace this change and work in a tripartite collaboration with patients and with the clinicians who use clinical laboratory services. Improved communication is the key to participation, including the provision of educational information and support. Knowledge management should be targeted to each stakeholder group. As part of collaborative healthcare clinical laboratory service provision needs to be more flexible and available, with implications for managers who oversee the structure and governance of the service. Increased use of managed point of care testing will be essential. The curriculum content of laboratory medicine training programs will require trainees to undertake practice-based learning that facilitates interaction with patients, clinicians and managers. Continuing professional development for specialists in laboratory medicine should also embrace new sources of information and opportunities for collaborative healthcare.

Egyptian imprints on Geto-Dacian magical medicine.

Several characteristics of Egyptian culture and civilization could be identified in prehistoric and ancient historic Geto-Dacian territories, belonging to modern Romania (Fig. 1). From early times, magic, religion and philosophy have been part of pre-scientific medicine. Therefore these aspects are to be tackled when speaking of medicine in mythological or legendary ages. Progress of ancient Geto-Dacian medicine was principally ascribed to the interface of local civilizations with ancient Egypt, Greece and Rome. Such connections were well documented and understood in historic times and were mainly based on texts of renowned Greek and Roman historians. Egyptian impact upon Dacia, -the ancient name of today's Romania-, was often explained in terms of indirect Greek- or Roman-mediated influences.The Greek and then the Roman colonies on the Black sea shore, together with later Roman colonies in Dacia Felix, founded in the heart of Transylvania, enabled access for Romania to Mediterranean cultures, including that of Egypt.

Justification of the hybrid nuclear medicine examinations

International Nuclear Information System (INIS)

Garcheva-Tsacheva, Marina B.

2015-01-01

The annual frequency of nuclear medicine examinations is increasing worldwide. This is partly a consequence of the recently introduced single photon emission tomography, combined with computed tomography, and positron emission tomography, combined with computed tomography, techniques, which combine functional, metabolic and morphological information important for the diagnosis of many diseases. However, since the effective radiation dose is the sum of the dose of two components, the hybrid examinations result in increased patient exposure. Accordingly, their justification becomes mandatory. It starts with their clinical importance-the opportunity to resolve a clinical problem decisive for patients' management. Knowledge of the indications, contraindications and the examinations' limitations is the responsibility of the nuclear medicine physician, as well as the choice of the most adequate examination and protocol. In conclusion, the cost and the accessibility of the examinations should not be the principal consideration as opposed to the diagnostic value and the exposure. Flexible protocols and algorithms should be used for hybrid nuclear medicine examinations. (authors)

Toxic pyrrolizidine alkaloids in herbal medicines commonly used in Ghana.

2017-04-18

Herbal medicines have been used for centuries for the management and treatment of various ailments due to the belief that they pose only little or no health risk and side effects, and also, in part, due to their availability, affordability and/or self-supply. However, the increasing information over the recent years on the occurrence of pyrrolizidine alkaloids (PAs) in honey, herbal food and tea products has raised concerns about the safety of herbal medicines with respect to contamination. To this day, little is known on the occurrence of toxic PAs in herbal medicines, especially in tropical West Africa. The aim of this study was therefore to determine the PA content of 70 well-known and widely patronized plant-derived medicinal preparations, which are commercialized in Ghana and some West African countries, in order to ascertain their potential health risk. PAs of the herbal medicinal products, sourced from specialized drugstores and mostly regulatory approved, were analyzed for their PA content by a HPLC-ESI-MS/MS sum parameter method. The results show that a total of 60% of the analyzed herbal products were PA positive, indicating an average PA-concentration of 25.0μg/kg. The maximum PA level (1290.0μg/kg) was attributed to a regulatory-approved herbal medicine not known, according to the list of declared ingredients, to contain PA-plant parts. Interestingly, higher PA content (average, 30.2μg/kg) was detected in regulatory-approved herbal medicines, in contrast to lower amount (average, 8.0μg/kg) detected in non-regulatory-approved products. The findings of this study clearly demonstrate that herbal medicines containing PA plants as ingredients, as well as some of those containing plant species not known to produce PAs, are likely to contain hepatotoxic PA at levels higher than the daily dose in food and herbal medicinal products proposed by the European Medicines Agency (i.e. 0.35μg PA per day for 50kg adult and 0.14μg PA per day for 20kg children

Few scholars of ancient medicine have considered that Hippocratic practice may be based in part upon the experience and tradition, handed-down from generation to generation, starting before the end of the Bronze Age in 1100 BC. This paper examines the evidence for medical practitioners in the Aegean in the second millennium BC, and of medical contacts between the Aegean and contemporary bronze age societies of Egypt and the Near East at this time, and suggests that some of these contacts may have been the start of Near Eastern influence on Greek medicine.

Morality and longevity in the viewpoint of Sasang medicine

2015-03-01

Full Text Available The concepts of morality and health of humans are discussed from the viewpoint of Sasang medicine, as described by Je-Ma Lee in his books Donguisusebowon and Gyeokchigo. Sasang medicine suggests that human beings exist with qualities of “heavenly loom,” “humanly affair,” and “nature and conduct in following parts.” In addition, Sasang medicine classifies people into the following four Sasang types: Tae-Yang, So-Yang, Tae-Eum, and So-Eum. This classification is based on the following traits: benevolence–righteousness–propriety–wisdom, manifestations of sorrow–anger–joy–pleasure (Seong and Jeong, and largeness and smallness of lung–spleen–liver–kidney. Human diseases are always caused by the excessive mind action of sorrow–anger–joy–pleasure. Mind action affects the body unilaterally and makes it ill. According to Sasang medicine, both good health and illness in human beings originate from morality. Therefore, realizing and acting in accordance with the right moral behavior are essential to lead a healthy life.

Full Text Available In traditional Chinese medicine theory (TCM, the affected parts of sprains, bruises and arthritis are considered to be under certain conditions of TCM concept. We administered two Kampo medicines with synergistic effects to promote quick recovery from these conditions. Jidabokuippo (Zhidapuyifang in Chinese, which means ‘decoction for contusions’ is expected to remove these conditions. Hachimijiogan (Baweidihuangwan in Chinese, which translates as ‘eight-ingredient pill with Rehmannia’ is expected to restore presumed minute bone injury and regulates bone metabolism by changing such conditions based on TCM theory. We administered the two prescriptions to 10 patients (age range: 40–85 years; 1 male, 9 females suffering from bruises, sprains, arthritis and spinal compression fracture without changing their routine intake of other drugs. Patients reported on changes in the pain of affected body parts by using the visual analog scale (VAS before and after administration of Kampo medicine. In almost all cases, recovery began promptly after administration and the pain disappeared within ∼2 weeks. Large doses for a short time brought about much quicker recovery than small doses. Administration of a combination of two Kampo medicines, Jidabokuippo and Hachimijiogan, quickly resolved the pain of bruises, sprains, arthritis and one spinal compression fracture.

In this article, we discuss our recent work in elucidating the mode-of-action of compounds used in traditional medicine including Ayurvedic medicine. Using computational ('in silico') approach, we predict potential targets for Ayurvedic anti-cancer compounds, obtained from the Indian Plant Anticancer Database given its chemical structure. In our analysis, we observed that: (i) the targets predicted can be connected to cancer pathogenesis i.e. steroid-5-alpha reductase 1 and 2 and estrogen receptor-β, and (ii) predominantly hormone-dependent cancer targets were predicted for the anti-cancer compounds. Through the use of our in silico target prediction, we conclude that understanding how traditional medicine such as Ayurveda work through linking with the 'western' understanding of chemistry and protein targets can be a fruitful avenue in addition to bridging the gap between the two different schools of thinking. Given that compounds used in Ayurveda have been tested and used for thousands of years (although not in the same approach as Western medicine), they can potentially be developed into potential new drugs. Hence, to further advance the case of Ayurvedic medicine, we put forward some suggestions namely: (a) employing and integrating novel analytical methods given the advancements of 'omics' and (b) sharing experimental data and clinical results on studies done on Ayurvedic compounds in an easy and accessible way.

Moral philosophy and psychology have sought to define the nature of right and wrong, and good and evil. The industrial turn of the twentieth century fostered increasingly technological approaches that conjoined philosophy to psychology, and psychology to the natural sciences. Thus, moral philosophy and psychology became ever more vested to investigations of the anatomic structures and physiologic processes involved in cognition, emotion and behavior--ultimately falling under the rubric of the neurosciences. Since 2002, neuroscientific studies of moral thought, emotions and behaviors have become known as--and a part of--the relatively new discipline of neuroethics. Herein we present Part 2 of a bibliography of neuroethics from 2002-2013 addressing the "neuroscience of ethics"--studies of putative neural substrates and mechanisms involved in cognitive, emotional and behavioral processes of morality and ethics. A systematic survey of the neuroethics literature was undertaken. Bibliographic searches were performed by accessing 11 databases, 8 literature depositories, and 4 individual journal searches, and employed indexing language for National Library of Medicine (NLM) Medical Subject Heading databases. All bibliographic searches were conducted using the RefWorks citation management program. This bibliography lists 397 articles, 65 books, and 52 book chapters that present (1) empirical/experimental studies, overviews, and reviews of neural substrates and mechanisms involved in morality and ethics, and/or (2) reflections upon such studies and their implications. These works present resources offering iterative descriptions, definitions and criticisms of neural processes involved in moral cognition and behaviors, and also provide a historical view of this field, and insights to its developing canon.

The Australian Nuclear Science and Technology Organisation (ANSTO) has a major research program in nuclear medicine; this article describes the information support given to the program by the Lucas Heights Research Laboratories (LHRL) Library. The INIS database is a prime indicator of the information held at LHRL Library, however, other databases also cover nuclear medicine. As part of the Australian library system the ANSTO Library's resources are accessed by subscription. The ANSTO Library staff can also search INIS for a fee for external enquiries but the other databases can presently only be searched for LHRL staff and affiliates. Even so, most major library and information services can provide access to these databases

As emergency medicine (EM) education evolves, a more advanced understanding of education scholarship is required. This article is the first in a series of three articles that reports the recommendations of the 2013 education scholarship consensus conference of the Academic Section of the Canadian Association of Emergency Physicians. Adopting the Canadian Association for Medical Education's definition, education scholarship (including both research and innovation) is defined. A rationale for why education scholarship should be a priority for EM is discussed.

The Chisobox experimental irradiator was installed at the Faculty of Medicine in Hradec Kralove, Radioisotope Laboratories and Vivarium, for the purposes of the scientific research of ionizing radiation effects on the living organisms. The irradiator was put into operation in 1977. After 1989, its use has been - significantly reduced and it was only employed for the sterilization of medical materials and aids as well as for the radiation treatment of antique and museum things having wood-worm. In January 2001, its next operation was determined by the SUJB decision (i.e. The State Office for Nuclear Safety) in which the constancy tests for all individual ionizing radiation sources being part of the system were required. As the f constancy tests were not performed at that time, the Faculty Management decided for the -- decommissioning of the irradiator in June 2001. In 2003, the Faculty of Medicine announced a tender for the category III workplace disposal. Primarily, the VF, a.s. in cooperation with the SURAO Prague (i.e. the Radioactive Waste Repository Authority) were to have disposed this workplace, and a hot cell designed to be built in Litomerice by the SURAO was to have been used for this project. However, the Faculty of Medicine got a grant for the irradiator disposal in 2004 providing that the disposal had to be finished in the same year. For this reason, the complete project has been assigned to the VF, a.s. Company, which put its hot cell into operation in 2004. The VF, a.s. Company finished the disposal of the irradiator in October/November 2004. After the agreement with the SURAO in April 2005, the sealed sources placed in the storage baskets were put into a newly manufactured container -a non-standard storage unit -and transported to be stored in the URAO Richard in Litomerice.

Traditional Chinese medicine (TCM), an alternative medicine, focuses on the treatment of human disease via the integrity of the close relationship between body and syndrome analysis. It remains a form of primary care in most Asian countries and its characteristics showcase the great advantages of personalized medicine. Although this approach to disease diagnosis, prognosis and treatment has served the medical establishment well for thousands of years, it has serious shortcomings in the era of modern medicine that stem from its reliance on reductionist principles of experimentation and analysis. In this way, systems biology offers the potential to personalize medicine, facilitating the provision of the right care to the right patient at the right time. We expect that systems biology will have a major impact on future personalized therapeutic approaches which herald the future of medicine. Here we summarize current trends and critically review the potential limitations and future prospects of such treatments. Some characteristic examples are presented to highlight the application of this groundbreaking platform to personalized TCM as well as some of the necessary milestones for moving systems biology of a state-of-the-art nature into mainstream health care.

Full Text Available Abstract The study of ethnobotany relating to any tribe is in itself a very intricate or convoluted process. This paper documents the traditional knowledge of medicinal plants that are in use by the indigenous Jaintia tribes residing in few isolated pockets of northeast India. The present study was done through structured questionnaires in consultations with the tribal practitioners and has resulted in the documentation of 39 medicinal plant species belonging to 27 families and 35 genera. For curing diverse form of ailments, the use of aboveground plant parts was higher (76.59% than the underground plant parts (23.41%. Of the aboveground plant parts, leaf was used in the majority of cases (23 species, followed by fruit (4. Different underground plant forms such as root, tuber, rhizome, bulb and pseudo-bulb were also found to be in use by the Jaintia tribe as a medicine. Altogether, 30 types of ailments have been reported to be cured by using these 39 medicinal plant species. The study thus underlines the potentials of the ethnobotanical research and the need for the documentation of traditional ecological knowledge pertaining to the medicinal plant utilization for the greater benefit of mankind.

Traditional systems of medicine have attained great popularity among patients in recent years. Success of this system in the treatment of disease warrants consideration, particularly in cases for which conventional medicine has been insufficient. This study investigates the similarities in principles and approaches of 3 traditional systems and explores whether conventional medicine is able to exploit the advantages of traditional systems. This study first identifies and explores the advantages of 3 well-known systems-traditional Iranian medicine (TIM), ayurveda, and traditional Chinese medicine (TCM)-that are similar in their basic principles and methods. Second, it clarifies whether and how conventional medicine could exploit the advantages of traditional systems as it modernizes, to become more personalized. Finally, this study investigates the possibility that conventional medicine could benefit from traditional typology to improve its personalization. The acknowledgment of the unity of humans and nature, applying rational methods, and personalized approaches is fundamentally similar in the 3 systems. Additionally, they all promote the holistic view that health is harmony and disease is disharmony of the body. Other similarities include their recognition of the unique nature of every person and their categorization of people into different body types. Although conventional medicine has mostly failed to incorporate the advantages of traditional medicine, its integration with traditional medicine is achievable. For instance, exploiting traditional typologies in genomic and other studies may facilitate personalization of conventional medicine. From its review, the research team concludes that prospects are bright for the integration of traditional and conventional medicines and, consequently, for a dramatic improvement in health systems.

Objective: One of the most common global disorders is related to gastrointestinal system. Functional dyspepsia (FD) defined as upper abdominal pain and discomfort in the absence of organic ailments is a prevalent disease without any confirmed medication. The purpose of this study was to find gastric disorders which might be coincidental to FD based on traditional Persian medicine (TPM). Materials and Methods: We searched the main textbooks of TPM including Al-Havi (by Rhazes), Canon of medicine (by Avicenna), ZakhireKhawrazmshahi (by Ismail Jorjani), Moalijat-e Aghili and Makhzan Al-adviya (by Mohammad Hosein AghiliShirazi), and ExirAzam (by Hakim Azam Khan). Also, we searched Pubmed, Scopus, Science Direct, Medline, scientific information database (SID), Iranmedex and Google Scholar from 1980 to 1 August 2014 for dyspepsia, gastrointestinal disease, traditional Persian medicine, and gastric dystemperaments. Results: There is no equivalent term for FD in traditional Persian medicine although similar signs and symptoms are visible in terms like simple cold dystemperament of stomach, indigestion, and digestion debility in TPM sources. Some treatments mentioned in TPM have shown promising results in the current experimental tests. Conclusion: Finding these similarities in complementary and alternative medicine (CAM) textbooks may lead to discovering new remedies for this widespread disease. PMID:27222829
