    Sudanese medicinal and aromatic plants (Alternanthra repens, Ambrosia maritima, Citrus paradisi, Croton zambesicus, Lepidium sativum, Morettia phillaena, Nauclea latifolia, Plectranthus barbatus, Pluchea dioscorides, and Sphaeranthus suaveolens) were analyzed for their chemical composition, mineral contents and secondary constituents. The concentration of manganese, copper, iron, nickel, lead, zinc and potassium in plant samples was performed using x-ray fluorescence spectrometry. The trace elements found in the smallest amount of the investigated plant species are lead, nickel and copper, while high concentration was detected for potassium, iron and manganese. Mn was accumulated with high level in Alternanthra repens species. Potassium was abundant in S. suaveolens and Ambrosia maritima. The values of concentration obtained for all studied elements were compared with published values of reference material, trace elements in Hay (powder) by International Atomic Energy Agency. Phyto chemical analysis of investigated plants was performed for constituents: Flavonoids, saponins, tannins, alkaloids, amino acids and sugars. The methanolic extracts of P.barbatus, C.paradisi, A.repens, N.latifolia, L. sativum and C. zambesicus are found to contain alkaloids. Results of TLC analysis were shown as R f values for saponins, bitter principles, essential oils, flavonoids and alkaloids. Quantification of flavonoids and tannins showed that flavonoid content was highest in case of Alternanthera repens and Sphaeranthus suavertens, whereas the highest tannin content was in case of Nauclea latifolia and Sphaearanthus suavertens. The results suggest that the user of traditional Sudanese crude drugs should be warned of potential danger of heavy metal poisoning because their concentrations seem to be higher than maximum values allowed by health agencies in several countries. This study has provided some biochemical basis for the ethno medical use of extracts from different candidate

    Hibiscus sabdariffa L. is a plant native to tropical Africa and intensively cultivated in Sudan. Its calyces are widely consumed with many uses in Sudanese folk medicine. The dried calyces of H. sabdariffa were subjected to soak in 80% v/v methanol to get the methanolic extract, which was tested against five Gram-negative and three Gram-positive referenced bacterial strains using disc diffusion method. Selected bioactive phytochemical compounds were also investigated using qualitative methods. The results of the antibacterial test indicate that the methanol extract of H. sabdariffa calyces contained effective antibacterial agent(s), revealed a considerable zone of inhibition against all tested Gram-negative and Gram-positive bacteria, and it was a competitor to gentamicin and greatly higher than penicillin which showed weak or no effect. The results of current investigation support the folk medicine application of this plant against different microbial ailments and suggest it as a promising source for new antibacterial agents.

    Ebtihal Abdalla M. Mohieldin

    Full Text Available Abstract In Sudan, some medicinal plants, such as Acacia seyal, Calotropis procera and Balanites aegyptiaca have been used to prevent or treat oral health problems. The stem and stem bark of Terminalia laxiflora Engl., Combretaceae, are used as antiseptics for mouthwash to prevent gingivitis and thrush in Africa. Methanol and 50% hydroethanolic extracts of 25 plants that are used in traditional Sudanese medicine for several diseases and cavity disorders were screened for anti-cavity activities. T. laxiflora methanolic wood extracts, which exhibited such activity, were investigated. The crude extracts were assayed for their antimicrobial activities against Streptococcus sobrinus in terms of minimum inhibitory concentration and glucosyltransferase inhibition. The active extract of T. laxiflora wood was subsequently fractionated by different chromatographic techniques. Isolated compounds were identified by spectroscopic methods and assessed for S. sobrinus and glucosyltransferase inhibitory effects. Methanolic extracts of Terminalia brownii (bark, T. laxiflora (wood, A. seyal (bark, Persicaria glabra (leaves and Tamarix nilotica (stem showed good activities against both S. sobrinus and glucosyltransferase (MIC ≤ 1 mg/ml, IC50 values <50 µg/ml. Over all plant extracts, T. laxiflora demonstrated the good combined activities (MIC 0.5 mg/ml, glucosyltransferase, IC50 10.3 µg/ml; therefore, its methanolic wood extracts were selected for further phytochemical studies. Four constituents were isolated by chromatographic techniques and identified by spectroscopic techniques. Pharmacological evaluation of the obtained compounds showed that flavogallonic acid dilactone had comparatively good antibacterial activity. In the glucosyltransferase inhibitory test, terchebulin displayed potent activity with an IC50 of 7.5 µM. The screening presented in this study showed that methanol extracts of T. laxiflora wood possessed promising anti-cavity effects.

    In this study was measured concentration of naturally occurring radionuclides 2 38U , 2 32T h and 4 0K in samples of sudanese medicinal plants. The radionuclide activity concentrations in samples analyzed ranged from 4.09 to 41.07 Bq kg -1 for 2 38T h and from 353.14 to 2270.21 Bq kg -1 for 4 0k . No trace of artificial radionuclide was determined in all the samples. The effective dose due to the presence of these radionuclides was estimated and found to be 0.524 mSv/year which is well below the permissible levels. (Author)

  7. Comparison between INAA and ICP-OES: analysis of Sudanese medicinal plants

    The aim of this study was to provide elemental concentrations in medicinal plants and mainly to compare the two different determination methods (INAA and ICP-OES after wet digestion) elemental analysis of 14 Sudanese medicinal plants was carried out using INAA and ICP-OES techniques. The selection of reported elements was done according to intersection of elements determined by both techniques. This intersecting element list contained Ca, K, Fe, Mn, Mg, Sr, Zn, Cu, Co, and Cr. INAA correlated well with ICP-OES measurements of the same plants as long as concentrations were sufficiently above LoQ. Correlation coefficients (R 2 ) in this case is close to 1. Generally, INAA results tended to be higher compared to ICP-OES. The performance and possible source of errors of both techniques was discussed also with respect to measurements of certified reference materials. INAA provided the advantage of having both, faster and non destructive sample preparation than ICP-OES. Therefore, INAA may be technique of choice for Ca, K, Zn, and Mg elements specifically when samples are needed for further investigations. Regarding the low concentrations e.g for Cr, Ni or Cu, ICP-OES is the superior technique over INAA due to the sufficiently low limits of determination and thus gaining more detectable results at low concentrations.

    2014-01-01

    Background Diabetes mellitus is a chronic metabolic disease with life-threatening complications. Despite the enormous progress in conventional medicine and pharmaceutical industry, herbal-based medicines are still a common practice for the treatment of diabetes. This study evaluated ethanolic and aqueous extracts of selected Sudanese plants that are traditionally used to treat diabetes. Methods Extraction was carried out according to method described by Sukhdev et. al. and the extracts were tested for their glycogen phosphorylase inhibition, Brine shrimp lethality and antioxidant activity using (DPPH) radical scavenging activity and iron chelating activity. Extracts prepared from the leaves of Ambrosia maritima, fruits of Foeniculum vulgare and Ammi visnaga, exudates of Acacia Senegal, and seeds of Sesamum indicum and Nigella sativa. Results Nigella sativa ethanolic extract showed no toxicity on Brine shrimp Lethality Test, while its aqueous extract was toxic. All other extracts were highly toxic and ethanolic extracts of Foeniculum vulgare exhibited the highest toxicity. All plant extracts with exception of Acacia senegal revealed significant antioxidant activity in DPPH free radical scavenging assay. Conclusions These results highly agree with the ethnobotanical uses of these plants as antidiabetic. This study endorses further studies on plants investigated, to determine their potential for type 2 diabetes management. Moreover isolation and identification of active compounds are highly recommended. PMID:24885334

    Fingerprints are important biometric variables that show manifold utilities in human biology, human morphology, anthropology, and genetics. Their role in forensics as a legally admissible tool of identification is well recognized and is based on their stability following full development, individualistic characteristics, easy classification of their patterns, and uniqueness. Nevertheless, fingerprint ridge density and its variability have not been previously studied in the Sudanese population. Hence, this study was conducted to analyze the topological variability in epidermal ridge density and to assess the possibility of its application in determining sex of Sudanese Arabs. The data used for this study were prints of all 10 fingers of 200 Sudanese Arab individuals (100 men and 100 women) aged between 18 and 28 years. Fingerprint ridge density was assessed for three different areas (radial, ulnar and proximal) for all 10 fingers of each subject. Significant variability was found between the areas (p crime scenes can be useful to determine sex of Sudanese individuals based on fingerprint ridge density; furthermore, ridge density can be considered a morphological trait for individual variation in forensic anthropology.

    Extracts of 111 Sudanese medicinal plants were subjected to preliminary antibacterial screening against four standard organisms (Bacillus subtilis, Stapylococcus aureus, Escherichia coli and pseudomonas aeruginasa). Out of the 573 extracts screened, 433 (70%) exhibited inhibitory activity against one ore more of the four tested bacteria. Most of the bioactive extracts (61%) showed inhibitory effects against the four organisms, while 11% were active against three, 20% against two and 8% against one organism. Based on the potent antibacterial activity and availability, eighteen plant species were selected and further extracted and subjected to antimicrobial investigation. About 38% of each of the methanolic and chloroformic extracts studied showed marked inhibitory effects against the tested organisms, where as the aqueous extracts exhibited less bioactivity (24%). None of these aqueous and methanolic extracts showed inhibitory against the two standard fungi tested (Aspergillus niger and candida albicans), while 97% of the chloroformic extracts exerted inhibitory effects against A. niger and 94% against C.albicans. On the basis of its prominent antimicrobial profiles against both bacteria and fungi tested, vernonia amygdalina was chosen as an appropriate candidate to pursue in depth phytochemical studies. the chloroformic extract which exhibited the most significant antimicrobial activity was subjected to bioactivity-directed fractionation. The bioactive fractions yielded two sesquiter-pene lactones, identified on the basis of their spectroscopical data (UV, IR, 1 H, NMR and mass spectroscopy) as vernodalin and vernolepin. Vernolepin has not been previously reported in this taxon, and it is the first time to publish the 13 C NMR of this compound. The present study established evidence of the potent antimicrobial activity of these two sesquiterpene lactones. The possible biogenetic pathway and structure/ activity relationships were discussed.

    Periodontal diseases are one of the major health problems and among the most important preventable global infectious diseases. Porphyromonas gingivalis is an anaerobic Gram-negative bacterium which has been strongly implicated in the etiology of periodontitis. Additionally, matrix metalloproteinases-9 (MMP-9) is an important factor contributing to periodontal tissue destruction by a variety of mechanisms. The purpose of this study was to evaluate the selected Sudanese medicinal plants against P. gingivalis bacteria and their inhibitory activities on MMP-9. Sixty two methanolic and 50% ethanolic extracts from 24 plants species were tested for antibacterial activity against P. gingivalis using microplate dilution assay method to determine the minimum inhibitory concentration (MIC). The inhibitory activity of seven methanol extracts selected from the 62 extracts against MMP-9 was determined by Colorimetric Drug Discovery Kit. In search of bioactive lead compounds, Combretum hartmannianum bark which was found to be within the most active plant extracts was subjected to various chromatographic (medium pressure liquid chromatography, column chromatography on a Sephadex LH-20, preparative high performance liquid chromatography) and spectroscopic methods (liquid chromatography-mass spectrometry, Nuclear Magnetic Resonance (NMR)) to isolate and characterize flavogalonic acid dilactone and terchebulin as bioactive compounds. About 80% of the crude extracts provided a MIC value ≤4 mg/ml against bacteria. The extracts which revealed the highest potency were: methanolic extracts of Terminalia laxiflora (wood; MIC = 0.25 mg/ml) followed by Acacia totrtilis (bark), Ambrosia maritima (aerial part), Argemone mexicana (seed), C. hartmannianum (bark), Terminalia brownii (wood) and 50% ethanolic extract of T. brownii (bark) with MIC values of 0.5 mg/ml. T. laxiflora (wood) and C. hartmannianum (bark) which belong to combretaceae family showed an inhibitory activity over 50% at

    Full Text Available This research investigates the influence of new media agendas on traditional news media according to the theoretical framework of intermedia agenda-setting during the 2010 Sudanese presidential elections. Upon applying content analysis, cross-lagged correlation analysis, and Rozelle-Campbell Baseline analysis, the paper provides evidence of intermedia agenda-setting in Sudanese media across a number of dependent variables. Sudanese newspapers influenced the agenda of Sudanese blogs whilst blogs have an increasing impact on the agenda of the newspapers. Our content analysis found that the agendas of socio-political blogs were strongly correlated with those of the newspapers. The findings also presented evidence of intermedia agenda-setting between socio-political blogs and citizen journalism.

    The aim of the present study is to identify and characterize the antimalrial agents from traitional Sudanese medicinal plants. 49 plants parts representing 26 species from 15 families were extracted and screened for their in vitro antimalrial activity using P. falciparum strain 3D7 which is chloroquine sensitive and Dd2 strain which is chloroquine resistant and pyrimethamine sensitive.The plant species investigated exhibited diverse botanical families. They includes Annonaceae, Aristolochiaceae, Asteraceae, Balantiaceae, Caesalpiniceae, Celasteraceae, Cucurbitaceae, Fabaceae, Graminae, Meliaceae, Myrtaceae, Polygonaceae, Rubiaceae, Rutaceae, and simaroubaceae. The evaluation of these plants for their antimalarial activity and their effect on lymphocyte proliferation was carried out. 57 extracts were tested on the chloroquine sensitive strain (3D7). Where 34 extracts (59%) exhibited significant activity against 3D7 with IC{sub 50} values {<=} 50 {mu} g/ml. While 21 extracts (57%) showed antimalrial activities with IC{sub 50} values {<=} 50 {mu} g/ml on Dd2. 13 extracts (22%) and ten extracts (18%) only showed an activity with IC{sub 50} values {<=} 5 {mu} g/ml on 3 D7 and Dd2, respectively. The activities of some plant extracts, which affected 3D7 strain, were measured using the radiolabelled ({sup 3}H) hypoxanthine method and microscopical count. 15 plant extracts (48%) from 32 showed IC{sub 50} values {<=} 50 {mu} g/ml against 3D7 strain using the radiolabelled hypoxanthine methods and only 5 extracts (16%) showed IC{sub 50} values {<=} 5 {mu} g/ml against 3D7. Most of the extracts screened had a low effect on lymphocyte proliferation (IC{sub 50} values >100 {mu} g/ml), where as Sonochous cornatus, Balanites aegyptiaca, Tamarindus indica, Acacia nilotica, Annona squamosa, Eucalyptus globulus and Cassia tora enhanced lymphocyte proliferation. liquid-liquid partition of methanolic preparation of Acacia nilotica seeds and husk showed that the ethylacetate phase

  7. Silver lining: building a shared Sudanese identity through food.

    Crofts, A V

    2010-01-01

    The displaced of Sudan, due to both decades of civil war and natural disasters, are disproportionately female and many are responsible for dependents. For those settling in the capital, Khartoum, their livelihood depends on carving out ways to earn money in an urban area that is experiencing tremendous growth from the millions of recent arrivals. When confronted with the immediate need to provide for their families, women turn to a skill universally expected of them: cooking. Therefore, Khartoum is home to a thriving micro-economy of food vendors. By selling these dishes in the capital, they broaden the culinary horizons of the city while preserving their own food traditions. Their growing numbers provide an opportunity for regional foodways to gain wider introduction, adaptation, and, finally, adoption. These same vendors also facilitate a nascent sense of a shared Sudanese identity and nationalism. For established Khartoum urbanites, the definition of Sudanese food (and, by extension, what it means to be Sudanese) expands as street-vendor fare moves to restaurants and becomes more widely available throughout the city. As urban Sudanese overcome their preconceptions and discover a taste for regional cuisines, meals function as unofficial diplomacy during this turbulent time in Sudan's history.

    1993-01-01

    A Vancouver, British Columbia, independent and its Sudanese partner have filed a development plan with the government of Sudan to produce an initial 40,000 b/d from Heglig and Unity oil fields in Sudan. Arakis Energy Corp., and the private Sudanese company State Petroleum Corp. (SPC) want to begin the first commercial hydrocarbon production in the destitute, war torn country. They are picking up where Chevron Corp. left off after years of grappling with an ambitious, costly - and ultimately futile - effort to export crude-oil from Sudan. After finding almost 300 million bbl of oil in Sudan during the early 1980s, Chevron scuttled a $2 billion project to export 50,000 b/d of Sudanese crude in 1986. It drilled 90 wells and sank more than $1 billion into the project. But it dropped the plan, citing the 1986 collapse of oil prices and concerns over security after repeated guerrilla attacks delayed work. The paper details the project

    Full Text Available Cynthia A Mannion, Shelley Raffin-Bouchal, Christena Jane HenshawFaculty of Nursing, University of Calgary, Calgary, Alberta, CanadaBackground: Refugees experience dietary changes as part of the daily challenges they face resettling in a new country. Sudanese women seek to care and feed their families, but face language barriers in the marketplace, limited access to familiar foods, and forced new food choices. This study aimed to understand the acceptability of a purse-sized nutrition resource, “The Market Guide”, which was developed to help recently immigrated Sudanese refugee women identify and purchase healthy foods and navigate grocery stores.Methods: Eight women participated in a focus group, four of whom were also observed during accompanied grocery store visits. Individual interviews were conducted with four health care workers at the resettlement center to gather perceptions about the suitability of The Market Guide. Focus groups and interviews were audiotaped and transcribed. Data from field notes and transcripts were analyzed using grounded theory for preliminary open codes, followed by selective and theoretical coding.Results: The Market Guide was of limited use to Sudanese women. Their response to this resource revealed the struggles of women acculturating during their first year in Calgary, Canada. We discovered the basic social process, “Navigating through a strange and complex environment: learning ways to feed your family.” Language, transportation, and an unfamiliar marketplace challenged women and prevented them from exercising their customary role of “knowing” which foods were “safe and good” for their families. The nutrition resource fell short of informing food choices and purchases, and we discovered that “learning to feed your family” is a relational process where trusted persons, family, and friends help navigate dietary acculturation.Conclusion: Emergent theory based on the basic social process may

    Full Text Available This paper examines the experiences of some Sudanese women working in the media. The paper brings to the center of analysis voices and experiences of women reporters, presenters, head of media sections, directors, and writers through adopting autobiographic and ethnographic research methods. The main question of this paper is how the “glass ceiling” metaphor-the invisible barriers that one, read women, can see through but not easily get through is applicable to the position of women in the media institutions of Sudan? Applying qualitative research methods, the paper found that Sudanese women journalists are constantly facing and negotiating gender disparities in work place, and poor working conditions; cultural/society’s perception of women working in the media; limited margin of press freedom in the country, and confronting the Islamist perception of the government of the Sudanese “woman”.

    Full Text Available The objective of this study was to assess the genetic relationships and diversity and to estimate the amount of gene flow among the five chicken populations from Sudan and South Sudan and commercial strain of egg line White Leghorn chickens. The chicken populations were genotyped using mtDNA D-loop as a molecular marker. PCR product of the mtDNA D-loop segment was 600 bp and 14 haplotypes were identified. The neighbor-joining phylogenetic tree indicated that the indigenous Sudanese chickens can be grouped into two clades, IV and IIIa only. Median joining networks analysis showed that haplotype LBB49 has the highest frequency. The hierarchal analysis of molecular variance (AMOVA showed that genetic variation within the population was 88.6% and the differentiation among the population was 11.4%. When the populations was redefined into two geographical zones, rich and poor Savanna, the results were fractioned into three genetic variations: between individuals within population 95.5%, between populations within the group 0.75%, and genetic variation between groups 3.75%. The pair wise Fst showed high genetic difference between Betwil populations and the rest with Fst ranging from 0.1492 to 0.2447. We found that there is large number of gene exchanges within the Sudanese indigenous chicken (Nm=4.622.

    2015-03-01

    Eumycetoma is a debilitating chronic inflammatory fungal infection that exists worldwide but it is endemic in many tropical and subtropical regions. The major causative organism is the fungus Madurella mycetomatis. The current treatment of eumycetoma is suboptimal and characterized by low cure rate and high recurrence rates. Hence, an alternative therapy is needed to address this. Here we determined the antifungal activity of seven Sudanese medicinal plant species against Madurella mycetomatis. Of these, only three species; Boswellia papyrifera, Acacia nubica and Nigella sativa, showed some antifungal activity against M. mycetomatis and were further studied. Crude methanol, hexane and defatted methanol extracts of these species were tested for their antifungal activity. B. papyrifera had the highest antifungal activity (MIC50 of 1 ug/ml) and it was further fractionated. The crude methanol and the soluble ethyl acetate fractions of B. papyrifera showed some antifungal activity. The Gas-Liquid-Chromatography hybrid Mass-Spectrophotometer analysis of these two fractions showed the existence of beta-amyrin, beta-amyrone, beta-Sitosterol and stigmatriene. Stigmatriene had the best antifungal activity, compared to other three phytoconstituents, with an MIC-50 of 32 μg/ml. Although the antifungal activity of the identified phytoconstituents was only limited, the antifungal activity of the complete extracts is more promising, indicating synergism. Furthermore these plant extracts are also known to have anti-inflammatory activity and can stimulate wound-healing; characteristics which might also be of great value in the development of novel therapeutic drugs for this chronic inflammatory disease. Therefore further exploration of these plant species in the treatment of mycetoma is encouraging.

    The estimation of stature from body parts is one of the most vital parts of personal identification in medico-legal autopsies, especially when mutilated and amputated limbs or body parts are found. The aim of this study was to assess the reliability and accuracy of using lower limb measurements for stature estimations. The stature, tibial length, bimalleolar breadth, foot length and foot breadth of 160 right-handed Sudanese Arab subjects, 80 men and 80 women (25-30 years old), were measured. The reliability of measurement acquisition was tested prior to the primary data collection. The data were analysed using basic univariate analysis and linear and multiple regression analyses. The results showed acceptable standards of measurement errors and reliability. Sex differences were significant for all of the measurements. There was a positive correlation coefficient between lower-limb dimensions and stature (P-value Arabs. Copyright © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    This study investigated differences in mental health knowledge and beliefs between participants from the Iraqi and Sudanese refugee communities, and Australian-born individuals, in Sydney, Australia. Ninety-seven participants were given vignettes of characters describing symptoms of major depressive disorder and posttraumatic stress. They were required to identify psychological symptoms as disorders, rate beliefs about the causes of and helpful treatments for these disorders, and rate attitude statements regarding the two characters. Australian participants recognized the presented symptoms as specific mental disorders significantly more than Iraqi and Sudanese participants did, and reported causal and treatment beliefs which were more congruent with expert beliefs as per the western medical model of mental disorder. The Sudanese group endorsed supernatural and religious causal beliefs regarding depression and posttraumatic stress symptoms most often; but both Sudanese and Iraqi participants strongly supported options from the supernatural and religious treatment items. However, evidence for pluralistic belief systems was also found. Although sampling was non-random, suggesting caution in the interpretation of results, it appears that the mental health literacy of lay Australians may be more aligned with the western medical model of mental disorder than that of Iraqi and Sudanese refugee communities. Mental health literacy support needs of Iraqi and Sudanese refugee communities resettled in western countries such as Australia might include education about specific symptoms and causes of mental disorder and the effectiveness of psychiatric treatments. These findings provide useful directions for the promotion of optimal service utilization among such communities.

    Malnutrition showed a high incidence among Sudanese children under five years of age. It affects directly the endocrine system of such children. In this the thyroid gland selected as a very important endocrine organ to be studied in 49 malnourished children under five years. Other 20 well- nourished children were selected to act as a control subjects . Both study and control groups were match for age and sex. The patients were seen and assessed for the disease in different hospital in Khartoum by consultant pediatrician. Thyroid function (thyroxineT4 and Triiodothyronine) was tested with a sensitive radioimmunoassay (RIA) technique. Some other biochemical parameters (hemoglobin Hb % total protein) were also investigated for the two groups (Patients and control) to confirm malnutrition. The means of the investigated parameters of the patients were compared with those of control group. The results showed 20 % of the malnourished children was complained of sever hypothyroidism (T4<25μmol/I) and (T3<0.3μmol/I) considering the normal range (55-142μmol/I) and (0.8-3μmol/I) respectively. The difference was highly significant together. The patients group showed low level in the two parameters, which indicate malnutrition. The the thyroid function in the malnourished children was severely affected by malnutrition, and such a test is strongly recommended to be a routine investigation for malnourished children.

    2016-01-01

    Given the persistent recurrence of armed conflict, influential actors owe it to the affected communities to take action. The legitimacy of health professionals to mitigate the effects of conflict relates to their ability to save lives and address the physical and mental consequences of armed conflict during which thousands of lives may be lost. Medical professionals have unique and potentially far-reaching skills. These become crucial during wartime and disasters in terms of providing medical services and humanitarian aid. However, they are insufficiently used in one area: involvement in politics as a tool to foster peace. Despite this, Sudanese individuals from medical backgrounds have participated actively in conflict resolution and peace-building processes. In fact, their political actions throughout the last six decades have aimed to prevent conflict at four different levels, which are described by Yusuf et al. in their article on the political involvement of health professionals in prevention. Their stand against President Nimeiri's Sharia laws was primordial prevention of religious conflict at the national level. Their leading role in the second Sudanese Intifada uprising was a key factor in saving the country from civil war, and another example of primary prevention. Sudanese physicians were also involved in secondary prevention by being influentially involved in almost all national peace agreements. Avoiding disputes at the tertiary level represents the weakest link in their repeated efforts. This paper outlines the different roles Sudanese medical personnel have taken in peacemaking. It also critically evaluates them in order to consider new methods of political involvement that suit future challenges.

    In this study fertility hormones were measured for 587 infertile Sudanese female referred from gynecological clinics. The ages of these female ranges from 16-50 years divided into seven groups. Eighty seven percent of them are in the age range between 21 and 40 year which correlate with the female's fertile period and 5.6% of them under 20 years. Sensitive (IRMA) method was used for measuring the hormone concentration. The objective of this study was to found out the percentage of hormonal disorders and its relation to the age in infertile Sudanese females. The age group (21-25) was the most affected group by the Poly Cystic Ovary Syndrome (PCOS) and represented 5.1% of the total number of patients. The least group was the age group (41-45) with a percentage of 0.4. The LH and the FSH in the age group of (31-35) was found to be higher than the other groups and represented 11.4% and 7.8% from the total number of patients respectively. The least percent of high level of LH and FSH was found to be in the most fertile age group (15-20) and it was 1.7% and 1.0% from the total number of studied patient, respectively. Those who were in the age range (26-30) with hyperprolactinaemia represented 10.4% of patients, while those with age rang (46-50) with hyperprolactinaemia represented the lowest percentage (1.2%). The percentage of patients having high LH and high FSH was 44.5% and 29.1% respectively, while the hyperprolactinaemia among the infertile Sudanese female was found to 38.2%.(Author)

    Background: There are differences in the distribution of ABO, sub group A BO and Rh(D) blood groups in different populations of the world. Relatively little information is available about blood group distributions in Sudanese population. To see the frequency of ABO, subgroup ABO and Rh(D) blood groups in major Sudanese ethnic groups(Danagla Shaygia and Gaaleen). Blood testing for ABO, subgroup ABO and Rh(D) typing was done over six months, in 300 unrelated individuals, from both genders. Blood samples were collected from students of the college of medical laboratory science - Sudan University of Science and Technology using finger prick method and following routine slide method. Blood group 'O' was the most predominant ( 52.7%) in both Rh positive and negative subjects followed by blood group A, B and AB. Majority (98.0%)o f the subjects were Rh(D) positive and only 2% were Rh negative. The predominant subgroup of ABO was A2 (14.1% ). The frequency of ABO blood groups in both Rh positive and negative subjects among the major Sudanese ethnic group was similar to that reported from neighbouring regions. (author)

    In this study fertility hormones were measured for 587 infertile Sudanese female referred from gynecological clinics. The ages of these female ranges from 16 - 50 years divided into seven groups. Eighty seven percent of them are in the age range between 21 and 40 year which correlate with the female's fertile period and 5.6% of them under 20 years. Sensitive (IRMA) method was used for measuring the hormone concentration. The objective of this study was to found out the percentage of hormonal disorders and its relation to the age in infertile Sudanese females. The age group (21 - 25) was the most affected group by the Poly-Cystic Ovary Syndrome (PCOS) and represented 5.1% of the total number of patients. The least group was the age group (41- 45) with a percentage of 0.4. The LH and the FSH in the age group of (31- 35) was found to be higher than the other groups and represented 11.4% and 7.8% from the total number of patients respectively. The least percent of high level of LH and FSH was found to be in the most fertile age group (15 - 20) and it was 1.7% and 1.0% from the total number of studied patient, respectively. Those who were in the age range (26 - 30) with hyperprolactinemia represented 10.4% of patients, while those with age range (46 - 50) with hyperprolactinemia represented the lowest percentage (1.2%). The percentage of patients having high LH and high FSH was 44.5% and 29.1% respectively , while the hyperprolactinemia among the infertile Sudanese female was found to 38.2%. (Authors)

    This study explored the impact of separation from family members on the mental health and wellbeing of Sudanese refugees in Australia, and the coping strategies used. In-depth interviews were conducted with Sudanese community representatives and health workers, primary and mental health care practitioners, health service managers and policy makers. Interviews were analysed using thematic analysis. Separation was perceived as having a negative impact on the mental health of Sudanese refugees in Australia, and manifested in concern about the safety of relatives abroad and in changing roles. The pressure to send money home emerged as a high priority for Sudanese refugees, often superseding local concerns. Several strategies were used to bridge the separation gap, including maintaining contact through the use of information communication technologies, and family-reunification. Separation from family can be an ongoing source of stress and sadness among refugees in countries such as Australia. While resettling refugees are actively taking steps to cope with the impact of separation, awareness of the issue in mainstream services appears to be low. Separation from family continues to affect refugees' lives in countries of resettlement. While it may be difficult to alter the course of the monumental circumstances that cause forced migration, service providers can support refugees' coping abilities by understanding these global-local intersections. © 2013 The Authors.

    2011-01-01

    Full Text Available The livestock sector of Sudan provides livelihood for about 17% of the population. Sudanese livestock products meet the domestic demand for meat in addition to a substantial excess for export amounting to about 22% of total country exports. It contributes about 19% of GDP. Sheep marketing in Sudan is characterised by traditional operations and is informally organised, although, recently there are great efforts by the formal livestock authorities to organise some secondary and terminal livestock markets. These markets are deficient in basic infrastructures and systematic marketing research. The system as a whole is faced by various complex obstacles and constraints, which decrease the contribution of livestock in general, and sheep in particular, to the national economy, and suppress the optimum exploitation of this resource. These obstacles are represented in the lack of transportation networks that connect the production and consumption centres to break the seasonality of supply that creates shortages and high prices at the consumption centres. This paper employs the policy analysis matrix (PAM technique to examine the Sudanese live sheep and mutton competitiveness in the international market. The results indicated that the market price was greater than the border price implying a positive incentive as an implicit subsidy to the live sheep exporter. The mutton exporters were found subsidised as well. The international value added (IVA indicted a positive foreign exchange earnings or savings. Exported live sheep and mutton coefficient of competitiveness (CIC implied that sheep and mutton exports are profitable and internationally competitive.

    Toombak is a local form of snuff widely used in Sudan. Dipping snuff is a common habit in Sudanese male subject. Many reports have related at the high incidence rate of oral cancer and other types of cancer in Sudanese subjects to this habit. trace elements such as Cu, Co, Cd, Cr, Fe, Mn, Pb, and Zn were measured using atomic absorption spectrometry in soil on which toombak is grown and toombak eaves. The average concentration (μg/g) of these elements in soil and toombak leaves were found to be 60.8 and 18.1 (Cu), 72.2 and 50.9 (Zn), 48.4 and 19.9 (Co), 398.6 and 211.7 (Mn), 17391.9 and 6410.7 (Fe), 16.1 and 5.3 (Cr), 27.7 and 7.9 (Pb), 7.2 and 4.8 (Cd), respectively. Soil to plant transfer factor was determined and found to be less than unity. The correlation coefficient between concentrations of trace elements in soils, and their soil-to-toombak transfer factors divided the elements into two groups, first group have inverse correlation while the second group is independent of their soil concentration.

    The objective of this study is to assess the presence of plaque, gingivitis, and caries in a group of Sudanese children with congenital heart defects CHDs (cases) and compare them to children without CHDs (controls). This analytical cross-sectional study included cases (N = 111, with a mean age of 7.2 ± 3.0 years) and controls (N = 182, with a mean age of 7.2 ± 2.8 years) from Khartoum, Sudan. Examinations were done by two calibrated dentists using plaque index, gingival index, and WHO (World Health Organization) caries diagnostic criteria (dmft/DMFT index: decayed, missing, and filled teeth). Children with CHDs (cases) had statistically significantly higher mean number of sites with plaque and gingivitis than children without CHDs (controls), although almost all children experienced plaque. Cases also experienced significantly higher mean dmft/DMFT than controls (age group 1, 3-7 years: 3.7 vs 2.3 and age group 2, 8-12 years: 1.3 vs 0.6). The Significant Caries Indices in cases (age groups 1 and 2) were also significantly higher than among controls (SiC 8.2 vs 5.9 and 1.8 vs 0.8, respectively). Fillings were totally lacking among cases and scarce among controls. The findings clearly showed that this group of Sudanese children with CHDs was more severely affected with gingivitis and caries than the control group without CHDs. These results are cause for concern in children at risk of developing systemic infections and serious complications related to poor oral health. These findings provide important baseline data for planning appropriate dental preventive strategies for Sudanese children with CHDs.

    Medical diaspora options, including the engagement of expatriate physicians in development efforts within their home country, are being called for to reverse the effects of brain drain from developing countries. This paper presents the results of a study exploring the potential contributions for the Sudanese Medial Diaspora Options to the healthcare delivery system (HCDS) in Sudan, focusing on the options of temporal and permanent returns and the likely obstacles faced in their implementation. This was a cross-sectional study using a mixed methods design including quantitative and qualitative approaches. For the quantitative approach, the study, which focused on the possible contribution of the diaspora to healthcare delivery in Sudan, was based on an online survey using random purposive and snowballing sampling techniques involving 153 Sudanese physicians working in Saudi Arabia and other Gulf States, the United Kingdom, the Republic of Ireland, and the United States of America. The qualitative approach involved in-depth interviews with returnee physicians and key informants in Sudan, focusing on the return experiences, the barriers for return, and the options to improve future contributions. Despite contributions of the Sudanese medical diaspora being of a small scale considering the size of the phenomenon, as well as infrequent and not appropriately organized, their inputs to academia and the links built with overseas institutions and specialist clinical services were nevertheless remarkable. The main barrier to temporal return was inappropriate organization by the local counterparts, while those for permanent return of physicians were poor work environment, insufficient financial payment, unsecured accommodation, and offspring education. The study identified short-term return as a feasible option considering the country's current conditions. Proper coordination mechanisms for short-term returns and facilitation of permanent return through stakeholders

    1995-06-01

    This study examines how Sudanese women are portrayed in the mass media. Data are obtained from a content analysis of historical records of Sudanese daily newspapers and women's magazines and from surveys among female editors in print media. The following types of newspapers are reviewed: independent newspapers; papers for the Al-Umma Party, a communist party, a Bathist party, a Muslim Nationalist Islamic Front Party, and a National Union Democratic Party; and a current military government paper. Women's magazines are published by women. Articles focus on women as the main newsmakers, women's life issues, female authors, a female focus but a male author, and famous Sudanese women. 16 content themes are identified. Women were not extensively featured or photographed in either newspapers or magazines. The Al-Umma Party paper and Al-Sudan Al-Hadith paper (an independent paper) were the only two newspapers with at least 10 photos of women. Women were pictured as professionals, educated persons, and leaders. There were 17 female editors. These editors preferred an image of women as leaders, followed by productive workers. Only 11.76% believed that women's dual roles as producers and reproducers should be portrayed. Female editors did not want a special women's page. 52.94% (the largest percentage) preferred targeting women with substantial leadership abilities. 17.65% desired the portrayal of women as workers and housewives. 58.82% did not think that the mass media image changed behavior or attitudes, because most Sudanese women are illiterate. Women's issues in both newspapers and women's magazines were devoted to women's work, achievements, and needs. The authors recommend removal of obstacles to women's equal participation in the mass media and press and research on the effect of media images on women's self-perception and behavior.

    The impact of trauma on refugee mental health has been a particular focal point for research and treatment in Western contexts, despite uncertainty about the degree to which this corresponds with refugees' needs, mental health beliefs and healing mechanisms. This study explored the mental health beliefs of resettling Sudanese refugees in Australia. In-depth qualitative interviews were conducted with Sudanese community representatives and with a range of health and social work professionals who were not necessarily Sudanese. The concept of trauma was not universally considered to be salient for Sudanese refugees. Key informants, especially those in refugee-oriented services, emphasised stoicism and a desire to move forward and questioned the appropriateness of Western psychological therapies. Processes that exist within the family and the Sudanese community to deal with stressors like loss, grief and social isolation were explained. Dialogue between services and community members is needed to ensure responses to refugee mental health are sensitive to the diversity of needs and mental health beliefs of refugees. This will enable workers to ascertain how individual refugees understand their experiences of distress or sadness and to determine whether community strategies and/or professional responses are appropriate. © The Author(s) 2015.

    Full Text Available Background/objective: The anatomy of vermiform appendix displays great variations in length and position between different populations. The reports relating these variations to a specific etiological factor are few. This study aims to describe the positions and lengths of vermiform appendix among Sudanese cadavers. Methods: This descriptive study was carried out in Omdurman Teaching Hospital Morgue and Omdurman Islamic University-Sudan. Sixty Sudanese cadavers (30 male and 30 female, were dissected in the period from June 2013 to June 2014. The positions and the lengths of vermiform appendix were measured in millimeters. The data was analyzed by SPSS version 20. Results: The cadavers’ age ranged between 20 to 80 years according to their medico-legal reports. Retrocaecal position was mainly observed in 60%, pelvic in 35%, post-ileal in 3.3%, and pre-ileal in 1.7%. The lengths of the appendix was found < 69 mm in 23.3%, 70-110 mm in 60%, and > 110 mm in 16.7%, also the study showed insignificant difference between the lengths and ages (p < 0.08, and between males and females (p = 0.23. Age was the influencing factor for the positions of vermiform appendixes (p = 0.04. Conclusion: The study showed that the commonest lengths of the appendix were 70-110 mm while the common position was retrocaecal regardless to age or gender. This data should be considered in surgical removal of the inflamed appendix.

    The aim of this study was to develop intergenerational understanding of the factors perceived to be influencing the sexual health and wellbeing of young Sudanese refugees in Queensland, Australia. Data from 11 semi-structured, face-to-face interviews exploring sexual health knowledge, attitudes and behaviours with young people aged 16 to 24 years, and five focus groups with adults from the broader Queensland Sudanese community, were compared and contrasted. Findings indicate that sexual health-related knowledge, attitudes and beliefs, along with patterns of sexual behaviour, are changing post-resettlement and this creates considerable intergenerational discord and family conflict. Study findings provide an understanding of how the interplay between traditional cultural gender, parenting and relationship norms and perceived normative Australian beliefs and patterns of behaviour influence the construction of both young people's and their parents' attitudes to sexual health post-arrival. We suggest that sexuality education programmes adapted to the specific cultural- and age-related contexts need to be introduced early within the resettlement process for both young people and their families.

    This study was conducted in order to identify the menopausal statues of Sudanese women which is critically important in determining the treatment strategy for infertile patients. In this study samples were collected from two hundred Sudanese women, aged between 35 and 62. They were from different social classes and are not suffering any systemic or endocrine disease. They were not exposed to any surgical intervention by complete hysterectomy or partial removal of ovaries or thyroidectomy. Reproductive hormones were determined for these women. Immunoradiometric Assay (IRMA) was adopted for the measurement of serum prolactin, follicle stimulating hormone, and luteinizing hormone. Enzyme linked immunosorbent assay (ELISA) was used for the determination of estradiol and esterone, whereas, enzyme immunoassay (tube format) was used for the determination of serum testosterone. Average menopausal age for Sudanese women was determined in this study and found to be 43.0±4.2 which is lower than that of the neighboring countries. A new classification system was developed during this study which uses a combination of symptoms together with hormonal profile in order to identify the menopausal status of women. The three key tools of this system are FSH and LH level together with the absence of menstrual cycle during the last three months. The new classification scheme had successfully differentiated the early peri-menopausal women from pre-menopausal ones. The early peri-menopausal women according to the new classification scheme are suffering cycle irregularities and amenorrhea but with normal hormonal levels. The new classification scheme is now, clearly indicating that amenorrhea with normal hormonal levels may be an indication to the beginning of the peri-menopausal life. The big challenge faced during this study had been the sub-classification of the peri-menopausal stage as it is not a single homogeneous stage but a wide heterogenous and transitional stage extending from

    Full Text Available Essential and nonessential heavy metals like iron (Fe, nickel (Ni, manganese (Mn, zinc (Zn, copper (Cu, cadmium (Cd, chromium (Cr, and lead (Pb were analyzed in four selected medicinal plants such as Capparis spinosa, Peganum harmala, Rhazya stricta, and Tamarix articulata by flame atomic absorption spectrophotometer (FAAS. These medicinal plants are extensively used as traditional medicine for treatment of various ailments by local physicians in the area from where these plants were collected. The concentration level of heavy metals in the selected plants was found in the decreasing order as Fe > Zn > Mn > Cu > Ni > Cr > Cd > Pb. The results revealed that the selected medicinal plants accumulate these elements at different concentrations. Monitoring such medicinal plants for heavy metals concentration is of great importance for physicians, health planners, health care professionals, and policymakers in protecting the public from the adverse effects of these heavy metals.

    Full Text Available The main objective of this study is to provide a database for renal transplantation in Sudan and to determine the HLA antigens and haplotype frequencies (HFs in the study subjects. HLA typing was performed using the complement-dependant lymphocytotoxicity test in 250 unrelated healthy individuals selected as donors in the Sudanese Renal Transplantation Program. Considerable polymorphism was observed at each locus; A2 (0.28, A30 (0.12, A3 (0.09, A24 (0.09, A1 (0.09, and A68 (0.06 were the most frequent antigens in the A locus, while B51 (0.092, B41 (0.081, B39 (0.078, B57 (0.060, B35 (0.068, B 50 (0.053 and B 52 (0.051 were the most common B locus antigens. DR13 (0.444 and DR15 (0.160 showed the highest antigen frequencies (AFs in the DR locus. In the DQ locus, DQ1 showed the highest gene frequency (0.498, while DQ2 and DQ3 AFs were (0.185 and (0.238, respectively. The most common HLA-A and -B haplotypes in positive linkage disequilibrium were A24, B38; A1, B7; and A3, B52. The common HLA-A and -B HFs in positive linkage disequilibrium in the main three tribe-stocks of the study subjects (Gaalia, Nile Nubian and Johyna were A24, B38 for Gaalia; A24, B38 and A2, B7 for Johyna; and A2, B64 and A3, B53 for Nile Nubian. These results suggest that both class I and class II polymorphisms of the study subjects depict considerable heterogeneity, which reflects recent admixture of this group with neighboring Arabs and African populations.

    Background Forced migration is associated with sexual vulnerability. However, little is known about the sexual health literacy and needs of refugee-background youth post resettlement. Conducted in partnership with the Queensland Sudanese community, this study used a cross-sectional survey to explore the sexual health knowledge, attitudes and behaviours of a convenience sample of 16- to 24-year-old Sudanese-background youth in Australia (n=229). Sexually transmissible infection (STI) and HIV knowledge scores were generally low, although they were found to significantly improve the longer participants had lived in Australia (Pbehaviour score suggests generally low levels of risk-taking behaviour. However, of the 140 sexually active participants, 3.1% reported a STI diagnosis, 9.0% reported sex leading to a pregnancy and 33.1% reported they had experienced unwanted sex. Participants also reported engaging in behaviours such as anal sex (33%) and sharing injecting drug equipment. Patterns of sexual behaviour among this predominately refugee-background group are not dissimilar to those of other young Australians. Nonetheless, the self-reported patterns of risk behaviour combined with the low and inaccurate levels of sexual health knowledge suggest this group of young people remain sexually vulnerable, particularly early within their resettlement experience. Culturally and contextually informed sexual health interventions are needed early within the resettlement experience.

    Vitamin C or ascorbic acid, a very useful constituent of redox mechanism is used in medicine and also added in manufactured food for anti-oxidation. A UV-spectrophotometric method was used for the determination of Vitamin C in 4 different medicinal plants. High amount of Vitamin C 160 mg/100 g was found in Citrulus colcocynthis, followed by Hippophae rhamonides oil 136.1 mg/100g. A relatively low concentration of Vitamin C was recorded in Glycyrhiza glabra 56.2 mg/100g and Withinia somnifera 51.50 mg/100 g. The presence of high concentration of Vitamin C in selected medicinal plants might be responsible for their therapeutic effects and uses in the traditional system of medicine. (author)

    2016-02-01

    Full Text Available Objective: To present an updated and compiled checklist of Sudanese seaweeds as an example for the region for conservational as well as developmental purposes. Methods: The checklist was developed based on both field investigations using line transect method at 4 sites along the Red Sea coast of Sudan and review of available studies done on Sudanese seaweeds. Results: In total 114 macroalgal names were recorded and were found to be distributed in 16 orders, 34 families, and 62 genera. The Rhodophyceae macroalgae contained 8 orders, 17 families, 32 genera and 47 species. The Phaeophyceae macroalgae composed of 4 orders, 5 families, 17 genera, and 28 species. The 39 species of the Chlorophyceae macroalgae belong to 2 classes, 4 orders, 12 families, and 14 genera. The present paper proposed the addition of 11 macroalgal taxa to be included in Sudan seaweeds species list. These include 3 red seaweed species, 1 brown seaweed species and 7 green seaweed species. Conclusions: This list is not yet inclusive and it only represents the macroalgal species common to the intertidal areas of Sudan Red Sea coast. Further investigation may reveal the presence of more species. While significant levels of diversity and endemism were revealed for other groups of organisms in the Red Sea region, similar work still has to be performed for seaweeds. Considering the impact of climate change on communities’ structure and composition and the growing risk of maritime transportation through the Red Sea particularly that may originate from oil tankers as well as that may emanate from oil exploration, baseline data on seaweeds are highly required for management purposes.

This study aims to assess metal levels which include Cadmium (Cd), Chromium (Cr), Copper (Cu), Nickel (Ni), and Lead (Pb) in cosmetic products. These elements have draft limits because they are identified as potential impurities and are known to be toxic. This study aims to provide information to the population that may be beneficial to public health. Samples were collected from different brands obtained from markets in Jordan, Sudan, and Syria. Some of the selected cosmetic products were eyeliner, eye pencil, mascara, lipstick, powder, face cream, body cream, sun block, Vaseline, and the traditional eye cosmetic (kohl). The heavy metal content in these samples were determined by atomic absorption spectrometry (AAS). Based on analysis of variance analysis, a significant difference in heavy metal levels was found for samples obtained from Jordanian and Sudanese markets. The acid digestion method used in this study was based on procedures recommended by Nnorom et al. with some modifications as follows. (i) A weight of 2.0 g of cosmetic sample was dissolved in a mixture of 6 mL of high quality concentrated 69% nitric acid (HNO 3 ; Merck, Darmstadt, Germany) and 4 mL of concentrated 37% hydrochloric acid (Scharlau, Spain) in a porcelain crucible and heated on a hotplate to near dryness. (ii) An aliquot of 15 mL HNO 3 (1.00 M) was added to the digested sample and filtered through a Whatman No. 40 filter paper. (iii) The digested sample was transferred quantitatively into a 25 mL volumetric flask and then diluted with deionized water. (iv) Each digested sample was evaporated at 70 °C to about 1 mL and transferred into a polyethylene flask and diluted with 25 mL deionized water. (v) Blank was treated in the same procedure. In Jordan the concentration ranges of heavy metals in the collected samples were: Cd (0.03-0.10 μg/g), Cr (0.0-1.00

    This study was conducted during the period from february 2004 to july 2004; with the objective of measuring the levels of estrogen (E2), carcinoembryonic antigen (CEA) and cancer antigen of breast (CA-15.3) so as to facilitate the early diagnosis of breast cancer and to determine the involvement of these parameters as risk factors for breast cancer. Ninety blood samples were collected from Sudanese females, divided into two groups; control group and patients groups. The patients group was sixty Sudanese females visiting the Radio Isotope Center, Khartoum (RICK) and they were confirmed as breast cancer patients by histopathology. The levels of the above mentioned parameters were determined by using radioimmunoassay technique. The results showed that , no significant (P=0.05) difference between the levels of the estrogen in patients compared to the control, on the other hand, there was non-significant (p<0.05) elevation in CEA levels in the patients with breast cancer compared to the control. The levels of CA 15.3 was significantly (p<0.0001) higher in the breast cancer patients compared to the control.(Author)

    Full Text Available Abstract Background Nasopharyngeal carcinoma (NPC is the most common cancer arising from the nasopharynx that varies significantly from other cancers of the head and neck in its occurrence, causes, clinical behavior, and treatment. NPC caused by an interaction between infection with EBV and environmental and genetic factors, encompasses a multistep oncogenic process. The frequency of Epstein-Barr virus EBV among nasopharyngeal carcinoma is well known worldwide, however, in the Sudan there is barely a published data. The aim of this study was to detect Epstein-Barr virus (EBV in nasopharyngeal carcinoma (NPC biopsies obtained from Sudanese patients using Polymerase Chain reaction. Methods This is a descriptive, retrospective hospital based study, conducted at the National Center for ENT diseases and the Faculty of Medical Laboratory Science, University of Khartoum, Khartoum City, Sudan. Archival blocks were obtained from 82 patients diagnosed as having nasopharyngeal carcinoma were molecularly examined for the presence of Epstein-Barr virus. Results Eighty two Paraffin fixed tissue sections were examined for the presence of the virus using PCR, EBV was identified in 51/ 82 (62.2% samples and couldn’t be identified in 31/ 82 (37.8% tissue samples. Out of the 51 infected samples, 33/51 (64.7% were found among males and 18/27 (66.7% were found among females. Conclusion The present study is providing strong evidence supporting the general association of EBV infection in NPC among Sudanese patients.

    The recounted experiences of an emergency support engineer revealed the importance of involving women in decision making at the local level. The task involved the provision of a gender sensitive technical program: a construction project to identify and supply safe, clean tap water for Sudanese refugees resettled in Uganda border areas where Ugandans had just returned as refugees in Zaire. There was squabbling among refugees because soap distribution was unsatisfactory, and a village elder revealed that corruption among elected officials was interfering with relief supplies. The village elder was able to notify an Oxfam spring technician, and other village women were consulted about suitable springs for providing permanent supplies during the dry season. Several springs were located, and one was selected. Six women helped prepare the spring for piped water, and, in the process, learned about spring technology. The location of tapstands was accomplished with village men and women mapping exact locations. Six taps were needed to serve a population of 100 people. Refugees helped with the digging of trenches, fixing the pipes, and assembling the tapstands. The operation took two weeks, but after the work was done, no one would use the tap water. A health educator consultant had to assure the villagers that the water was safe. Within days, villagers and refugees were using the tap water. Street theater was used to convey another health message about the importance of water tap maintenance. As a consequence, six men and women formed a sanitary committee to make certain the areas remained clean and well drained and that water was not wasted. Committee members were trained to make simple repairs. The lesson learned was that women can be effectively involved at the local level, if one listens intently, talks with women, and watches behavior carefully.

    In this study 672 pregnant Sudanese women were involved in order to determine the reference values of human chorionic gonadotropin (HCG) and alpha feto protein (AFP). Blood samples were collected from different maternity centers in Khartoum and Omdurman maternity. Sensitive immunoradiometric assay (IRMA), method was used for measuring HCG and AFP in maternal serum. The data collected reveals that, the behavior of both AFP and HCG resemble that of the international one, where the peak concentrations of HCG are reached at 7-9 weeks of pregnancy then decrease, then staying relatively constant during the second trimester and increasing slightly towards term. The maternal serum concentration of AFP increases during pregnancy, reaching its peak during the last trimester. The concentration of AFP and HCG in maternal serum with relative couples was also compared to that of ir relative couples. Relative couples showed significant increase in maternal AFP level in the first and third trimesters (p=0.001and 0.000) respectively. The HCG concentration in both groups was not significantly different throughout the pregnancy (p>0.15). It is recommended that each laboratory establishes its own normal values. Since sudanese obstetrician depends previously on values from abroad, this study may help them to handle their patients depending on our own reference values.(Author)

    Full Text Available Abstract Background There is a growing interest in high income countries to control expenditure on medicines by improving the rationale for their selection. However, in middle income countries with differing priorities and needs, little attention has been paid to this issue. In this paper we explore the policies and processes for the selection and use of medicines in a group of hospitals in Chile, a middle income country which has recently joined the OECD. Methods A combination of qualitative and quantitative methods was used. A national survey questionnaire was distributed to investigate the role and operation of PTCs (Pharmacy and Therapeutics Committees. Interviews were conducted with key actors in the selection of medicines in large urban public hospitals. Results The national survey had an overall response rate of 42% (83 out of 196, whilst 7 out of 14 hospitals participated in the qualitative study. High complexity hospitals are large urban hospitals; all of which claim to have a working PTC. The pharmacy offices are mainly involved in dispensing medicines with little involvement in clinical duties. The interviews conducted suggest that the formulary of all the hospitals visited is no more than a stock list. PTCs are unable to influence the prescribing practices of doctors. Members do not feel prepared to challenge the opinions of specialists requesting a certain drug, and decisions are based primarily on costs. The inclusion of medicines in the clinical practice of hospitals is as a result of doctors bypassing the PTC and requesting the purchase of exceptional items, some of which are included in the formulary if they are widely used. Conclusions There is an urgent need to develop medicine policies in hospitals in Chile. The procedures used to purchase medicines need to be revised.

    The external ear and its prints have multifaceted roles in medico-legal practice, e.g., identification and facial reconstruction. Furthermore, its norms are essential in the diagnosis of congenital anomalies and the design of hearing aids. Body part dimensions vary in different ethnic groups, so the most accurate statistical estimations of biological attributes are developed using population-specific standards. Sudan lacks comprehensive data about ear norms; moreover, there is a universal rarity in assessing the possibility of sex estimation from ear dimensions using robust statistical techniques. Therefore, this study attempts to establish data for normal adult Sudanese Arabs, assessing the existence of asymmetry and developing a population-specific equation for sex estimation. The study sample comprised 200 healthy Sudanese Arab volunteers (100 males and 100 females) in the age range of 18-30years. The physiognomic ear length and width, lobule length and width, and conchal length and width measurements were obtained by direct anthropometry, using a digital sliding caliper. Moreover, indices and asymmetry were assessed. Data were analyzed using basic descriptive statistics and discriminant function analyses employing jackknife validations of classification results. All linear dimensions used were sexually dimorphic except lobular lengths. Some of the variables and indices show asymmetry. Ear dimensions showed cross-validated sex classification accuracy ranging between 60.5% and 72%. Hence, the ear measurements cannot be used as an effective tool in the estimation of sex. However, in the absence of other more reliable means, it still can be considered a supportive trait in sex estimation. Further, asymmetry should be considered in identification from the ear measurements. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Objective(s: In an attempt to discover new natural active extracts against malaria parasites, the present study evaluated the antiplasmodial properties of selected plants based on Iranian traditional medicine. Materials and Methods: Ten plant species found in Iran were selected and collected based on the available literature about the Iranian traditional medicine. The methanolic extracts of these plants were investigated for in vitro antimalarial properties against chloroquine-sensitive (3D7 and multi-drug resistant (K1 strains of Plasmodium falciparum. Their in vivo activity against Plasmodium berghei infection in mice was also determined. Cytotoxicity tests were carried out using the Raji cells line using the MTT assay. The extracts were phytochemically screened for their active constituents. Results: According to the IC50 and selectivity index (SI values, of the 10 selected plant species, Citrullus colocynthis, Physalis alkekengi, and Solanum nigrum displayed potent in vitro antimalarial activity against both 3D7 and K1 strains with no toxicity (IC50= 2.01-18.67 µg/ml and SI=3.55 to 19.25.  Comparisons between treated and untreated control mice showed that the mentioned plant species reduced parasitemia by 65.08%, 57.97%, and 60.68%, respectively.  The existence of antiplasmodial compounds was detected in these plant extracts. Conclusion: This was the first study to highlight the in vitro and in vivo antiplasmodial effects of             C. colocynthis, P. alkekengi, and S. nigrum in Iran. Future studies can use these findings to design further biological tests to identify the active constituents of the mentioned plant species and clarify their mechanism of action.

    There is increasing awareness about the association of sleep quality and academic achievement among university students. However, the relationship between sleep quality and academic performance has not been examined in Sudan; this study assessed the relationship between sleep quality and academic performance among Sudanese medical students. A case-control study was conducted among 165 male and female medical students at two Sudanese universities. Excellent (A) and pass (C) academic groups were invited to respond to a self-administered questionnaire, using the Pittsburgh Sleep Quality Index (PSQI). Students also completed a diary detailing their sleep habits for 2 weeks prior to filling out the questionnaire. Various parameters of sleep quality were then compared between the two groups. A significant difference (p sleep quality, subjective sleep rating, bedtime later than midnight, sleep latency, and daytime dysfunction (during driving, preparing a meal, etc.). No differences were found between groups for the use of sleep medications. The mean sleeping hours was (7 ± 1.9) and (6.3 ± 1.9) for the excellent and pass groups respectively (p < 0.05). A significant difference (p < 0.001) between the excellent and average groups was found for weekday and weekend bedtime, weekend wake-up time, and weekend wake-up delay. No differences were found between groups for the weekday's wake- up time, and bedtime delay during weekends. Besides, snoring was present in 9.2 % of the excellent group versus 28 % in pass group (p < 0.005).

    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.

    Recently, the popularity of internal medicine residency has been decreasing. We studied the effect of an improved working environment and a decrease in residents' workload on the selection of internal medicine residency. An organizational diagnosis team joined our department and identified several causes for residents' heavy workload. These findings were subsequently discussed in a workshop and led to a modification of the daily routine and a parallel decrease in workload and rise in residents' satisfaction. Following these changes, the demand for residency in our department rose. We conclude that an improvement in the working environment and workload during residency increases the residents' satisfaction and the demand for residency in internal medicine.

    To explore the process of partnership between university researchers, students, and South Sudanese refugee women to address the health challenges associated with their resettlement transition to the United States. This qualitative study used a community-based collaborative action research (CBCAR) framework in the design, collection, and analysis of the qualitative data. Twenty refugee women participated in this study. Five health education seminars followed by an audio-recorded focus group were held over 9 months. A final focus group was held to confirm derived themes and develop an action plan. The partnership between the refugee women and researchers resulted in awareness of how power structures and differing expectations affected the process. The dialog in the focus groups provided an opportunity for refugee women to voice challenges to their health in resettlement. A pattern was recognized about how political and sociocultural events affected the process of CBCAR. Dialog and sharing differing worldviews and perspectives led to insights about ways to improve the health of the South Sudanese refugee community. CBCAR is a useful framework to address health concerns of a refugee community. Insights from this study provided a foundation for a future intervention research project with the refugee women. © 2015 Wiley Periodicals, Inc.

    Medicines are becoming a major component of health expenditure in China. Selection of effective and cost-effective medicines represents an important effort to improve medicines use. A guideline on cost-effectiveness studies has been available in China. This guideline, however, fails to be a practical tool to prepare and critically appraise economic evidence. This article discusses, in the Chinese context, the approach to integrating economic component into the medicines selection, and elaborates the methods of producing economic evidence, including conducing economic reviews and primary economic studies. © 2010 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

    Activity concentrations of Pu isotopes in surface marine sediments collected from the Sudanese coast of the Red Sea is presented. The following concentration ranges were determined: 238 Pu, 4.7-28.6 mBq/kg; 239+240 Pu, 53-343 mBq/kg dry weight. The average activity ratios of 238 Pu/ 239+240 Pu (0.075 ± 0.045 mBqk/kg) and 239+240 Pu/ 137 Cs (0.026 ± 0.025 mBq/kg) are appropriately comparable to the literature values that are characteristic of the global fallout from the atmospheric nuclear weapon tests. However, 239/240 Pu/ 137 Cs ratio in sediments collected from the biologically rich fringing reef is an order of magnitude higher compared to other sampling locations. (author)

    This study deals with the determination of thyroid related hormones (T4,T3 and TSH) levels in sudanese patients with end-stage renal disease (ESRD) and under haemodialysis to determine the best means of treatment. This is the first time in Sudan to investigate thyroid related hormones on patients with chronic renal failure and was done on 61 patients and 60 symptoms-free subjects as controls. Radioimmunoassay (RIA) technique is used for the determination of serum total T4 and T3,whereas, TSH was determination using immunoradiometric assay (IRMA). T-test calculation revealed that the mean concentrations of total T4 and T3 of the patients were much lower than that of the normal subjects (p 0.05).These results revealed that, serum total T4 levels tent to decline after long term treatment with haemodialysis. Serum total T3 level fluctuate in lower margin of the normal range in haemodialyzed patients. As serum total thyroxine (T4) tends to decline in haemodialyzed patients, the use of thyroxine replacement therapy is highly recommended. (Author)

    Quality in laboratory medicine is often described as doing the right test at the right time for the right person. Laboratory processes currently operate under the oversight of an accreditation body which gives confidence that the process is good. However, there are aspects of quality that are not measured by these processes. These are largely focused on ensuring that the most clinically appropriate test is performed and interpreted correctly. Clinical quality indicators were selected through a two-phase process. Firstly, a series of focus groups of clinical scientists were held with the aim of developing a list of quality indicators. These were subsequently ranked in order by an expert panel of primary and secondary care physicians. The 10 top indicators included the communication of critical results, comprehensive education to all users and adequate quality assurance for point-of-care testing. Laboratories should ensure their tests are used to national standards, that they have clinical utility, are calibrated to national standards and have long-term stability for chronic disease management. Laboratories should have error logs and demonstrate evidence of measures introduced to reduce chances of similar future errors. Laboratories should make a formal scientific evaluation of analytical quality. This paper describes the process of selection of quality indicators for laboratory medicine that have been validated sequentially by deliverers and users of the service. They now need to be converted into measureable variables related to outcome and validated in practice.

    Prostate cancer is one of the most common malignancies worldwide, with an estimated 40,000 new case diagnosed annually. Insulin-like growth factor-1 (IGF-1) is important to the growth and function of prostate gland, but its incidence and mortality have been associated with increased circulating IGF-1 levels and this causes a high risk to the prostate gland cells in development of cancer. To fulfill these hypotheses we do a prospective study of prostate gland in Sudanese men at the Physicians Urology Health department in Khartoum State hospitals (2004-2009) to assayed circulating levels of IGF-1, PSA, E2 and testosterone among 110 known cases of prostate cancer (Ca.P), 110 benign prostate hyperplasia (BPH) and 110 matched controls subjects (CG). Using non isotopic enzyme methods of Enzyme Linked Sorbent Assay (ELISA), kits produced from Germany DRG company and sensitive micro plate reader and SPSS and ANOVAS one way statistic programme to analysis the data. So when we compare these three groups with ages, types of cancers, and the IGF-1, PSA, E2 and testosterone parameters, there was significant (p=0.04) and the associations between these hormones parameters was (p=0.01). Also when we compare the IGF-1 levels at 95% of upper quartiles of confidence interval in CG group (180ng/ml) with the IGF-1 levels at 25% of lower quartiles of confidence interval in the (Ca.P) and (BPH) group (165ng/ml) and (134ng/ml) respectively, the CG-IGF-1 group was higher than (Ca.P and BPH) groups at these percentiles, with associations between them of (p=0.05). This apparent discrepancy of the risk fallen to the normal (CG) group can be explained using the risk ratio (RR), odds ratio (OR) and confidence interval (CI) with Ca.P patients groups, (OR 2.4, 95% CI 0.71-7.9) (RR 2.3, 95% C10.7-7.1), showing that the risk fallen to the (CG) group was ten (10) times higher than the known cancer patients of the Ca.P, with significant of (p=0.05). So there were associations between high circulating

    Medicinal plants are used by many ethnic groups as a source of medicine for the treatment of various ailments in both humans and domestic animals. These plants produce secondary metabolites that have antimicrobial properties, thus screening of medicinal plants provide another alternative for producing chemical fungicides that are relatively non-toxic and cost-effective. Leaf extracts of selected South African plant species ( Bucida buceras, Breonadia salicina, Harpephyllum caffrum, Olinia ventosa, Vangueria infausta and Xylotheca kraussiana ) were investigated for activity against selected phytopathogenic fungi ( Aspergillus niger, Aspergillus parasiticus, Colletotricum gloeosporioides, Penicillium janthinellum, P. expansum, Trichoderma harzianum and Fusarium oxysporum ). These plant fungal pathogens causes major economic losses in fruit industry such as blue rot on nectaries and postharvest disease in citrus. Plant species were selected from 600 evaluated inter alia, against two animal fungal pathogens ( Candida albicans and Cryptococcus neoformans ). Antioxidant activity of the selected plant extracts were investigated using a qualitative assay (2, 2-diphenyl-1-picrylhydrazyl (DPPH)). Bioautography assay was used to determine the number of antifungal compounds in plant extracts. All plant extracts were active against the selected plant phytopathogenic fungi. Moreover, Bucida buceras had the best antifungal activity against four of the fungi, with minimum inhibitory concentration (MIC) values as low as 0.02 mg/ml and 0.08 mg/ml against P. expansum, P. janthinellum, T. harzianum and F. oxysporum . The plant extracts of five plant species did not possess strong antioxidant activity. However, methanol extract of X. kraussiana was the most active radical scavenger in the DPPH assay amongst the six medicinal plants screened. No antifungal compounds were observed in some of the plant extracts with good antifungal activity as shown in the microdilution assay, indicating

    The unpredictable nature of precipitation within the East African (EA) region makes it one of the most vulnerable, food insecure regions in the world. There is a vital need for forecasts to inform decision makers, both local and regional, and to help formulate the region's climate change adaptation strategies. Here, we present a suite of different seasonal forecast models, both statistical and dynamical, for the EA region. Objective regionalization is performed for EA on the basis of interannual variability in precipitation in both observations and models. This regionalization is applied as the basis for calculating a number of standard skill scores to evaluate each model's forecast accuracy. A dynamically linked Land Surface Model (LSM) is then applied to determine forecasted flows, which drive the Sudanese Hydroeconomic Optimization Model (SHOM). SHOM combines hydrologic, agronomic and economic inputs to determine the optimal decisions that maximize economic benefits along the Sudanese Blue Nile. This modeling sequence is designed to derive the potential added value of information of each forecasting model to agriculture and hydropower management. A rank of each model's forecasting skill score along with its added value of information is analyzed in order compare the performance of each forecast. This research aims to improve understanding of how characteristics of accuracy, lead time, and uncertainty of seasonal forecasts influence their utility to water resources decision makers who utilize them.

    2015-03-01

    Full Text Available Knowledge about evidence-based medicine selection and the role of the Drug and Therapeutics Committee (DTC is an important topic in the literature but is scarcely discussed in Brazil. Our objective, using a qualitative design, was to analyze the medicine selection process performed in four large university hospitals in the state of Rio de Janeiro. Information was collected from documents, interviews with key informants and direct observations. Two dimensions were analyzed: the structural and organizational aspects of the selection process and the criteria and methods used in medicine selection. The findings showed that the DTC was active in two hospitals. The structure for decision-making was weak. DTC members had little experience in evidence-based selection, and their everyday functions did not influence their participation in DTC activities. The methods used to evaluate evidence were inadequate. The uncritical adoption of new medicines in these complex hospital facilities may be hampering pharmaceutical services, with consequences for the entire health system. Although the qualitative approach considerably limits the extent to which the results can be extrapolated, we believe that our findings may be relevant to other university hospitals in the country.

    Residency program selection is a significant experience for emerging physicians, yet there is limited information about how applicants narrow their list of potential programs. This study examines factors that influence residency program selection among medical students interested in family medicine at the time of application. Medical students with an expressed interest in family medicine were invited to participate in a 37-item, online survey. Students were asked to rate factors that may impact residency selection on a 6-point Likert scale in addition to three open-ended qualitative questions. Mean values were calculated for each survey item and were used to determine a rank order for selection criteria. Logistic regression analysis was performed to identify factors that predict a strong interest in urban, suburban, and rural residency programs. Logistic regression was also used to identify factors that predict a strong interest in academic health center-based residencies, community-based residencies, and community-based residencies with an academic affiliation. A total of 705 medical students from 32 states across the country completed the survey. Location, work/life balance, and program structure (curriculum, schedule) were rated the most important factors for residency selection. Logistic regression analysis was used to refine our understanding of how each factor relates to specific types of residencies. These findings have implications for how to best advise students in selecting a residency, as well as marketing residencies to the right candidates. Refining the recruitment process will ensure a better fit between applicants and potential programs. Limited recruitment resources may be better utilized by focusing on targeted dissemination strategies.

    Despite the established role of the Pap smear test (PST) in prevention and early detection of cervical cancer, it is still rarely practiced in Sudan. Many challenges hinder the establishment of an effective cervical cancer screening program, including socio-cultural factors. Therefore, this study aimed to investigate the knowledge, attitudes and practices (KAP) of Sudanese women with regard to the Pap smear test and cervical cancer. A total of 500 married women aged 14 to 58 years were recruited from obstetric clinics, hospitals and universities in Khartoum in 2014. Data were collected using a standardized, pretested questionnaire that inquired socio-demographic characteristics and their KAP about cervical cancer and the PST. More than 52% of participating women were above 30 years of age, and the majority (78.8%) were university degree holders. A total of 486 (97.2 %) of participants were resident in urban areas of Khartoum State. However about 48% of the respondents had never heard about PST, and only 15.8% of the participants had undergone a Pap smear test previously; 46.6% (233/500) knew that the human papilloma virus (HPV) was the causative agent, but only 39.2% (196/500) had heard about HPV vaccination, and only 11.4% (57/500) had received the vaccine. However 68% of the respondents agreed to do Pap smear if properly informed about the test and 75.4% of the respondents agreed to participate in a cervical cancer screening program. Despite a high educational level, less than half of our participants had accurate knowledge about cervical cancer, HPV, and cervical cancer screening. Health education about cervical cancer, HPV and sexually transmitted infections and the role of PST in cervical cancer prevention are crucial when designing interventions aimed at improving cervical cancer screening for Sudanese women.

    Full Text Available Vesicoureteral reflux (VUR is a common congenital renal tract anomaly in children. Reports from Sudan are scanty. We report the characteristics, presentation and outcome of primary VUR in a tertiary care hospital. The records of 30 patients (16 males; 53% followed-up between January 2004 and December 2010 were reviewed. The mean age at the time of diagnosis was 4 ± 3.9 years and 47% were <2 years of age. Renal ultrasound scan (USS failed to predict VUR in 17% of the patients. On voiding cysturethrogram (VCUG, VUR was bilateral in 57% and severe grade in 64%. Grades were not significantly associated with age, gender or site of VUR. Initial dimercaptosuccinic acid radionuclide scan showed renal damage in 61.5% of the patients. Renal damage was significantly associated with female gender and severe VUR, but not with age of onset or history of urinary tract infection (UTI. Thirteen patients (43.3% presented with acute UTI, eight (26.6% with non-specific urinary tract symptoms and nine (30% with persistently elevated serum creatinine. Urine cultures were positive in 73% of patients, and E. coli was the most common pathogen. Renal impairment at presentation was significantly associated with bilateral severe VUR and history of UTI but not age or gender. After a mean follow-up period of 1.78 years (6 months to 5 years, 70% of patients remained with normal renal function and 30% progressed to chronic kidney disease; two of them died. In conclusion, our data is different from many studies. Features of primary VUR in Sudanese children are late age of onset, equal gender affection and predominance of severe grade. Presentation is associated with a high rate of UTI, renal damage and advanced renal impairment. Measures to improve early detection and treatment of VUR may reduce the risk of kidney damage.

METHODS This article is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015, a cross-sectional study that consisted of an information gathering in a sample of cities in the five regions of Brazil. The data used were collected by interviews with those responsible for pharmaceutical services (PS (n = 506, professionals responsible for the dispensing of medicines (n = 1,139, and physicians (n = 1,558. To evaluate the difference between ratios, we adopted the Chi-square test for complex samples. The differences between the averages were analyzed in generalized linear models with F-test with Bonferroni correction for multiple comparisons. The analyses considered significant had p≤0.05. RESULTS The professionals responsible for pharmaceutical services reported non-existence of a formally constituted Pharmacy and Therapeutics Committee (PTC (12.5%. They claimed to have an updated (80.4% list of Essential Medicines (85.3% and being active participants of this process (88.2%. However, in the perception of respondents, the list only partially (70.1% meets the health demands. Of the interviewed professionals responsible for the dispensing of medicines, only 16.6% were pharmacists; even so, 47.8% reported to know the procedures to change the list. From the perspective of most of these professionals (70.9%, the list meets the health demands of the city. Among physicians, only 27.2% reported to know the procedures to change the list, but 76.5% would have some claim to change it. Most of them reported to base their claims in clinical experiences (80.0%. For 13.0% of them, the list meets the health demands. CONCLUSIONS As this is the first national survey of

    Full Text Available Background: Vitiligo is the most common pigmentary skin disorder. It is a multifactorial polygenic disease with epidermal melanocyte destruction. The cytokines profile found in vitiliginous patients was not fully elucidated. Aims: We sought to assess the autoimmune nature of vitiligo by comparing plasma levels of interleukin (IL-17, IL-23, and transforming growth factor beta (TGF-b in adult Sudanese vitiligo patients with matched control individuals. Subjects and Methods: Case-control study was conducted in Khartoum Dermatologic Teaching Hospital, in the period between July and December 2013. The cases were 42 adult Sudanese vitiligo patients matched with 43 control individuals. The cytokines were measured in the plasma by the quantitative "sandwich" ELISA. Results: Patients showed a significant lower median (25-75 th inter-quartile of TGF-β than control (0.042 [0.041-0.044] vs. 0.047 [0.042-0.049]; P ͳ 0.001. Both IL-17 and IL-23 showed no significant difference between cases and controls. IL-17 showed a significant inverse relationship when correlated with TGF-β (r = −0.24; P = 0.026 while showing direct relationship when correlated with age (r = 0.28; P = 0.009. Conclusion: The positive findings detected in this study coincide with the important immunoregulatory role of the TGF-β, and support the autoimmune nature of the disease.

    Access to medicines is a universal right. Low availability and low affordability of medicines are issues that deny this right to a significant proportion of the world population. The objective of this study was to determine the availability, price and affordability of essential medicines prescribed to treat non communicable diseases in Sri Lanka. Methodology was based on the 2nd edition of the World Health Organization Health Action International Manual. A country survey was conducted and facilities representing both public and private pharmacies were selected. A total of 109 facilities was surveyed. At each facility data on the availability and prices of 50 essential medicines for non communicable diseases were collected. Percentage availability, median price of originator brand and lowest priced generic, median price ratio to the International Reference Price were calculated for surveyed medicines. Affordability was determined using the daily incomes of the lowest--paid unskilled government worker. Semi government community pharmacies had the highest (>80%) availability while outdoor pharmacies of public health care facilities, private pharmacies and outdoor pharmacies of private hospital showed a fairly high availability (50 - 80%) of surveyed medicines.Unit price of 76% of selected individual medicines was less than ten Sri Lankan rupees. Out of these 28% of medicines cost less than one Sri Lanka rupee. For 21 of the surveyed medicines the median price ratio to the international reference price was less than one. The prices of originator brands for 14 surveyed medicines were more than five times that of the lowest price generics.Less than a single day's wages was adequate to purchase a month's supply of the lowest priced generic of more than 67% of surveyed medicines. The availability of selected essential medicines was fairly high in both public and private sectors in Sri Lanka. Most medicines are affordable to the lowest income earners in the community. There

    The function of the thyroid gland is under the control of pituitary gland through the thyroid stimulating hormone (TSH). It secretes the thyroid hormones tetra-iodo-thyronine (T 4 ) and Tri-iodo-thyronine (T 3 ). More secretion of thyroid hormones (hyperthyroidism) and low secretion (hypothyroidism) sometimes happen. This study was carried out to determine thyroid disorders in patients referred to radioimmunoassay (RIA) laboratory of Sudan Atomic Energy Commission (SAEC) during 2006-2010 for the thyroid function test. Disorders were detected using radioimmunoassay and Immuno radiometric assay. The total number of patients referred during these years were found to be 4700 sudanese patients, among them 4165 were females representing 88.6% compared to 535 males representing 11.4%. The total concentration of thyroid hormones thyroxine (T 4 ), tri iodine thyronine (T 3 ) and thyroid simulating stimulating hormones (TSH) were d terminated the prevalence of euthyroid was (66.5%), hypothyroidism was (11.8%) and of hyperthyroidism was (21.7%). These percentages did not vary significantly with sex. (Author)

    Objective: The aims of this study were to determine the prevalence of hypodontia in the permanent dentition in a sample of Sudanese patients who sought orthodontic treatment and to compare the results with the reported findings of other populations. Materials and Methods: Orthodontic files including orthopantomographs of 1069 patients (760 females and 309 males - more than 8 years old) were examined and inspected for evidence of hypodontia. Results: The prevalence of hypodontia of the present sample was 5.1%. Hypodontia was found considerably more frequently in the mandible than in the maxilla. The distribution of missing teeth was noticed in the left side more than in the right side. The most frequently missing teeth were the maxillary lateral incisors, followed by the mandibular second premolars, maxillary second premolars and mandibular left lateral incisor. The majority of patients had two or three teeth missing, but rarely more than 5 teeth missing. Conclusions: The prevalence of hypodontia of this study was within the range of that reported in the literature. The incidence of hypodontia in the anterior segment requires great need for orthodontic and prosthodontic treatment. With early detection of hypodontia, alternative treatment modalities can be planned and performed with a multidisciplinary team approach restoring the esthetic and function. PMID:25143929

    Selective laser sintering (SLS) 3-dimensional printing is currently used for industrial manufacturing of plastic, metallic and ceramic objects. To date there have been no reports on the use of SLS to fabricate oral drug loaded products; therefore, the aim of this work was to explore the suitability of SLS printing for manufacturing medicines. Two thermoplastic pharmaceutical grade polymers, Kollicoat IR (75% polyvinyl alcohol and 25% polyethylene glycol copolymer) and Eudragit L100-55 (50% methacrylic acid and 50% ethyl acrylate copolymer), with immediate and modified release characteristics respectively, were selected to investigate the versatility of a SLS printer. Each polymer was investigated with three different drug loadings of paracetamol (acetaminophen) (5, 20 and 35%). To aid the sintering process, 3% Candurin ® gold sheen was added to each of the powdered formulations. In total, six solid formulations were successfully printed; the printlets (3D printed tablets) were robust, and no evidence of drug degradation was observed. In biorelevant bicarbonate dissolution media, the Kollicoat formulations showed pH-independent release characteristics, with the release rate dependent on the drug content. In the case of the Eudragit formulations, these showed pH-dependent, modified-release profiles independent of drug loading, with complete release being achieved over 12h. In conclusion, this work has demonstrated that SLS is a versatile and practical 3D printing technology which can be applied to the pharmaceutical field, thus widening the armamentarium of 3D printing technologies available for the manufacture of modern medicines.

    The risk of Plasmodium falciparum infection is variable over space and time and this variability is related to environmental variability. Environmental factors affect the biological cycle of both vector and parasite. Despite this strong relationship, environmental effects have rarely been included in malaria transmission models.Remote sensing data on environment were incorporated into a temporal model of the transmission, to forecast the evolution of malaria epidemiology, in a locality of Sudanese savannah area. A dynamic cohort was constituted in June 1996 and followed up until June 2001 in the locality of Bancoumana, Mali. The 15-day composite vegetation index (NDVI), issued from satellite imagery series (NOAA) from July 1981 to December 2006, was used as remote sensing data.The statistical relationship between NDVI and incidence of P. falciparum infection was assessed by ARIMA analysis. ROC analysis provided an NDVI value for the prediction of an increase in incidence of parasitaemia.Malaria transmission was modelled using an SIRS-type model, adapted to Bancoumana's data. Environmental factors influenced vector mortality and aggressiveness, as well as length of the gonotrophic cycle. NDVI observations from 1981 to 2001 were used for the simulation of the extrinsic variable of a hidden Markov chain model. Observations from 2002 to 2006 served as external validation. The seasonal pattern of P. falciparum incidence was significantly explained by NDVI, with a delay of 15 days (p = 0.001). An NDVI threshold of 0.361 (p = 0.007) provided a Diagnostic Odd Ratio (DOR) of 2.64 (CI95% [1.26;5.52]).The deterministic transmission model, with stochastic environmental factor, predicted an endemo-epidemic pattern of malaria infection. The incidences of parasitaemia were adequately modelled, using the observed NDVI as well as the NDVI simulations. Transmission pattern have been modelled and observed values were adequately predicted. The error parameters have shown the smallest

    Background The risk of Plasmodium falciparum infection is variable over space and time and this variability is related to environmental variability. Environmental factors affect the biological cycle of both vector and parasite. Despite this strong relationship, environmental effects have rarely been included in malaria transmission models. Remote sensing data on environment were incorporated into a temporal model of the transmission, to forecast the evolution of malaria epidemiology, in a locality of Sudanese savannah area. Methods A dynamic cohort was constituted in June 1996 and followed up until June 2001 in the locality of Bancoumana, Mali. The 15-day composite vegetation index (NDVI), issued from satellite imagery series (NOAA) from July 1981 to December 2006, was used as remote sensing data. The statistical relationship between NDVI and incidence of P. falciparum infection was assessed by ARIMA analysis. ROC analysis provided an NDVI value for the prediction of an increase in incidence of parasitaemia. Malaria transmission was modelled using an SIRS-type model, adapted to Bancoumana's data. Environmental factors influenced vector mortality and aggressiveness, as well as length of the gonotrophic cycle. NDVI observations from 1981 to 2001 were used for the simulation of the extrinsic variable of a hidden Markov chain model. Observations from 2002 to 2006 served as external validation.

    Full Text Available This study is primarily investigating teachers’ perceptions about the application of oral corrective feedback in Sudanese EFL classrooms. It attempts to explore and rationalize the application of oral feedback in an EFL context, specifically in Sudan. For this purpose, a questionnaire was designed and distributed to (70 EFL secondary school teachers. An observation checklist was also used during class visits to further support the qualitative data. The results showed that EFL teachers have different views about giving oral corrective feedback. The findings also revealed that recast is the most commonly used approach, followed by elicitation and metalinguistic feedback, respectively. Clarification requests were found to be the least commonly used approach. Regarding teaching language systems, it was found that recasts is the most common approach used in teaching vocabulary and pronunciation whereas metalinguistic is highly preferred in teaching grammar. The study concluded with some relevant recommendations: First, it is the responsibility of the concerned authorities to make the school environment a better place for learning; class size and learning aids are important to help facilitate the role of the teacher in offering good quality teaching where feedback is provided for every learner. Second, educators and experts should hold regular seminars and conferences, issue magazines and periodicals on feedback and other relevant ELT topics. Moreover, teachers should be trained on how to give feedback on oral production. Finally, teachers should push students towards pair/group work because by doing so this will provide opportunities for ST-ST and T-ST feedback.

    This work was carried out mainly to analysis of some Sudanese phosphate ores, for their uranium abundance and total phosphorus content measured as P 2 O 5 %. For this purpose, 30 samples of two types of phosphate ore from Eastern Nuba Mountains, in Sudan namely, Kurun and Uro areas were examined. In addition, the relationship between uranium and major, and trace elements were obtained, also, the natural radioactivity of the phosphate samples was measured, in order to characterize and differentiate between the two types of phosphate ores. The uranium abundance in Uro phosphate with 20.3% P 2 O 5 is five time higher than in Kurun phosphate with 26.7% P 2 O 5 . The average of uranium content was found to be 56.6 and 310 mg/kg for Kurun and Uro phosphate ore, respectively. The main elements in Kurun and Uro phosphate ore are silicon, aluminum, and phosphorus, while the most abundant trace elements in these two ores are titanium, strontium and barium. Pearson correlation coefficient revealed that uranium in Kurun phosphate shows strong positive correlation with P 2 O 5 , and its distribution is essentially controlled by the variations of P2O5 concentration, whereas uranium in Uro phosphate shows strong positive correlation with strontium, and its distribution is controlled by the variations of Sr concentration. Uranium behaves in different ways in Kurun phosphate and in Uro phosphate. Uro phosphate shows higher concentrations of all the estimated radionuclides than Kurun phosphate. According to the obtained results, it can be concluded that Uro phosphate is consider as secondary uranium source, and is more suitable for uranium recovery, because it has high uranium abundance and low P 2 O 5 %, than Kurun phosphate.

    An anatomical study was carried out on mature leaves of five selected medicinal species of Rubiaceae from Peninsular Malaysia. The chosen medicinal species were Aidia densiflora, Aidia racemosa, Chasallia chartacea, Hedyotis auricularia and Ixora grandifolia. The objective of this study is to determine the taxonomic value of midrib anatomical characteristics. Leaves samples were collected from Taman Paku Pakis, Universiti Kebangsaan Malaysia, Bangi, Selangor and Kledang Saiong Forest Reserve, Perak, Malaysia. Leaves samples then were fixed in spirit and acetic acid (3:1), the midrib parts then were sectioned using sliding microtome, cleared using Clorox, stained in Safranin and Alcian blue, mounted in Euparal and were observed under light microscope. Findings in this study have shown all species have collateral bundles. The midrib vascular bundles characteristics that can be used as tool to differentiate between species or genus are vascular bundles system (opened or closed), shape and arrangement of main vascular bundles, presence of both additional and medullary vascular bundles, position of additional vascular bundles, shape of medullary vascular bundles, presence of sclerenchyma cells ensheathed the vascular bundles. As a conclusion, midrib anatomical characteristics can be used to identify and discriminate medicinal plants species studied in the Rubiaceae.

    Several Cecropia (Cecropiaceae) species are traditionally used in Latin America for the treatment of a variety of diseases including diabetes, arterial hypertension, asthma, bronchitis, anxiety, and inflammation. At present, a number of commercial products based on these plants have been introduced into the market with very little information on methods for guaranteeing their quality and safety. This work proposes potential chemical markers for the quality control of the raw materials of Cecropia obtusifolia Bertol., Cecropia peltata L., Cecropia glaziovii Snethl., Cecropia pachystachya Trécul, and Cecropia hololeuca Miq. The Herbal Chemical Marker Ranking System (Herb MaRS) developed by the National Institute of Complementary Medicine (NICM) at the University of Western Sydney was used for selecting chemical markers for the quality control of selected medicinal species of Cecropia. This review covers the period from 1982 to 2016. Chlorogenic acid, flavonoidal glycosides (orientin, isoorientin, vitexin, isovitexin, and rutin), catechin, epicatechin, procyanidins (B2, B5, and C1), steroids (β-sitosterol), and triterpenoids (α-amyrin, pomolic, tormentic and ursolic acids) were selected as chemical markers for the quality control of the leaves. It is necessary to establish comprehensive standards for guaranteeing quality, safety and efficacy of herbal drugs. The selection of adequate chemical markers for quality control purposes requires a good knowledge about the chemical composition of medicinal plants and their associated biological properties. To the best of our knowledge this review article is the first to address the identification and quantitative determination of the chemical markers for the genus Cecropia.

    Full Text Available Objective: To evaluate the antimicrobial activity of methanolic extracts of six marine macroalgae belonging to green algae (Chlorophyceae, brown algae (Phaeophyceae and the red algae (Rhodophyceae collected from the intertidal area of the Sudanese Red Sea coast near Port Sudan. Methods: Methanol was used for extracting the active principles of the algae and the disc diffusion method was performed to examine the activity and the minimum inhibitory concentration of the samples against four pathogenic bacteria and two fungi. Results: All tested algal extracts exhibited considerable bioactivity and inhibited the growth of all pathogenic microorganisms under investigation. The green alga Caulerpa racemosa produced the maximum inhibition zone (21 mm against Candida albicans while the red alga Laurencia papillosa showed low antimicrobial activity with the minimum inhibition zone of 10 mm against Pseudomonas aeruginosa. The tested algal extracts did not show any special antimicrobial influence on the selected microorganisms when they were considered as Grampositive and Gram-negative bacteria and fungi but the most efficient methanolic extracts in inhibiting microbial growth were those of green macroalgae followed by the brown and the red macroalgae respectively. Conclusions: The study demonstrated that the tested marine macroalgae from Sudanese Red Sea coast may represent a potential and alternative source for secondary metabolites with antimicrobial activity.

    2014-05-01

    Full Text Available The dictionary should always be present in language education. It is the tool with which EFL teachers can effectively perform teaching tasks in their classes. Good teachers should take on the habit of consulting their dictionaries to assimilate the lexical, syntactical, phonological, morphological, etymological and more other features of one word or expression that a good dictionary can provide. This paper is investigating the attitudes of English language teachers in the use of this important teaching aid. It is an additional viewpoint from EL teachers in four Sudanese State Universities on the use of dictionary in their classes. The findings of this research might be of significance to other researchers, teachers, language learners and textbook designers; and the results may be applicable in many similar EFL environments round the globe.

    Due to escalating conflicts and resultant economic constraints, different social services in low income and low-middle income countries have witnessed a decline in its standards, and increase in the costs. This situation has led to emergence of large numbers of patients and their families who cannot afford the costs of health services provided by public hospitals. On this background, and the old heritage of the Sudanese to help the needy, the Hawadith Street Initiative (HSI) was established. Named after the street on which it was founded - which translates indirectly to "Accidents Lane", HSI was established in 2012 by a group of youths, most of them in their twenties of age, and recently graduated. The main activity of the initiative is helping the needy hospital patients, especially with regards to their treatment costs, in Khartoum and other cities in Sudan. Starting with recreational programs for cancer patients, and public campaigns for donation of blood, the initiative's youths changed their activities. Using the social media, Facebook, they adopted the strategy of communication with potential donors, after sending posts containing brief anonymous presentations and call of help for needy cases. Currently HSI includes more than 2000 volunteers in Khartoum and 17 other cities. The most important achievement of HSI is the establishment of an intensive care unit at a children hospital in Omdurman city costing 435,880 US dollars. HSI demonstrates the possibility of delivering great services with minimum resources, and constitutes a unique organization, worldwide, in a new wave of Internet-based initiatives.

    Full Text Available Access to financial service has become a key phenomenon for economic development and poverty alleviation .Microfinance is one way of fighting poverty in Sudan, where most citizens are in need of it. However, despite the initial results showing a positive impact of microfinance on the livelihood of low-income people in Sudan, around 8 million of the Sudanese poor people are excluded from microfinance services. One potential remedy for the limited outreach of microfinance in Sudan may lie within enhancing the capacity of microfinance services providers (MFPs in the utilization of modern technology. Recent innovation in providing financial services in a convenient and efficient way is the use of mobile banking (m-banking technology in microfinance. M-banking promises to increase the efficiency and outreach of microfinance services in developing countries. This paper tries to examine the factors that influence the adoption of m-banking by microfinance sector in Sudan. In this respect, hypotheses were developed guided by Unified Theory of Acceptance and Use of Technology (UTAUT and Technology-organization-Environment (TOE models. Primary data were collected from MFPs and microfinance customers in Sudan using questionnaires and interviews. The study contributes to knowledge in terms of methods used by extending aforementioned theories through adding new variables to both models by putting both models in one study to fill the gaps in past studies; via examination of the demand (customers and supply (institutions through modifying them to include new variables related to m-banking in microfinance.

After his graduation from the Kitchener School of Medicine (renamed, Faculty of Medicine, University of Khartoum [U of K]) in 1934, he devoted his life for the development of laboratory medicine. He became the first Sudanese Director of Stack Medical Research Laboratories (1952 - 1962). He made valuable contributions by his services in the vaccine production and implementation programs, most notably in combating small pox, rabies and epidemic meningitis. In 1963 he became the first Sudanese Professor of Microbiology and Parasitology and served as the first Sudanese Dean of the Faculty of Medicine, U of K (1963-1969). He was an active loyal citizen in public life and served in various fields outside the medical profession. As Mayor of Omdurman, he was invited to visit Berlin in 1963 by Willy Brandt, Mayor of West Berlin (1957-1966) and Chancellor of the Federal Republic of Germany (1969 to 1974). Also as Mayor of Omdurman, he represented the City in welcoming Queen Elizabeth II during her visit to Sudan in February 1965. He also received State Medals from Egypt and Ethiopia. In 1973 he was appointed Chairman of the Sudan Medical Research Council, and was awarded the international Dr. Shousha Foundation Prize and Medal by the WHO for his contribution in the advancement of health, research and medical services.

    Full Text Available Ethnopharmacological studies are important for documenting and protecting cultural and traditional knowledge associated with the medical use of biodiversity. In this paper, we present a survey on medicinal plants used by locals in a community of Nova Viçosa, Viçosa, MG, Brazil, as a strategy to select medicinal plants for a phytotherapy-based local healthcare program. Eleven knowledgeable local informants were chosen by snowball sampling and interviewed about the use of medicinal plants. Plant samples were collected, herborised and then identified using traditional techniques and specialised literature. We sampled 107 medicinal plant species belonging to 86 genera and 39 families, predominantly Asteraceae with 16 species. Costus spicatus (Jacq. Sw, M. pulegium L., Rosmarinus officinalis L. and Ruta graveolens L. were found to have Consensus of Main Use corrected (CMUc values above 50%, which were in agreement with the traditional uses described by the informants. However, species with CMUc values equal to or above 20%, combined with the scientific information survey, were also used to select medicinal plants for the phytotherapy-based local healthcare program. The selection of medicinal plants based on the CMUc index from this particular community, in combination with the scientific survey, appears to be an effective strategy for the implementation of phytotherapy programs.Estudos etnofarmacológicos são importantes no registro e na preservação de conhecimentos de uma cultura tradicional associada ao uso medicinal da biodiversidade.

    2012-01-01

    A study was conducted to determine the degree of tooth loss, factors influencing tooth loss, and the extent of prosthodontic rehabilitation in Sudanese adults (≥ 16 years old) attending outpatient clinics in Khartoum State. Pearson and multivariate analyses were used to examine the relationships between tooth loss and specific characteristics determined through interviews and clinical examinations. The mean number of missing teeth was 3.6 (SD, 4.9) and the prevalence of edentulism was 0.1%. The prevalence of tooth loss (missing at least one tooth) was 78%; 66.9% of tooth loss was due to caries, and 11.2% was attributable to other reasons. Prosthetic replacement of missing teeth was evident in 3%, whereas a need for prosthetic replacement was evident in 57%. Having teeth was associated with age, gender, and socioeconomic status; tooth loss due to caries was associated with age, tribe, frequency of tooth-brushing, and a low rate of dental consultation. Tooth loss due to other reasons was associated with age, tribe, education, periodontal pocketing, tobacco use, tooth wear, and prosthetic status. The results of the present study indicated that the major cause of tooth loss was dental caries, thus emphasizing the importance of a public prevention-based healthcare program. Replacement of missing teeth was uncommon in the study subjects, which may reflect lack of access to this type of oral healthcare.

    2012-05-01

    Evolution has long provided a foundation for population genetics, but some major advances in evolutionary biology from the twentieth century that provide foundations for evolutionary medicine are only now being applied in molecular medicine. They include the need for both proximate and evolutionary explanations, kin selection, evolutionary models for cooperation, competition between alleles, co-evolution, and new strategies for tracing phylogenies and identifying signals of selection. Recent advances in genomics are transforming evolutionary biology in ways that create even more opportunities for progress at its interfaces with genetics, medicine, and public health. This article reviews 15 evolutionary principles and their applications in molecular medicine in hopes that readers will use them and related principles to speed the development of evolutionary molecular medicine.

    To detect the effect of some maternal risk factors such as age, parity, previous heavy babies and family history of diabetes, in glucose tolerance impairment and to stand on the state of insulin resistance which occurs in pregnancy and the possible role of cortisol, human placental lactogen and prolactin in augmentation of this state of insulin resistance as well as to show the effect of glucose tolerance deterioration on lipid metabolism, a study was carried out on Sudanese pregnant women. The study included thirty gestational diabetes mellitus (GDM) pregnant women, thirty impaired glucose tolerance (IGT) and thirty women with normal glucose tolerance as a control group. The GDM, IGT and the control group were screened from about 2000 Sudanese pregnant women in the different gestational weeks. The GDM and IGT women were all discovered in the third trimester of pregnancy, they found to be significantly older than the control group. The IGT group was found to have a first degree family history of diabetes incidence significantly more than that of the control group while the GDM group has significantly much higher results when compared with the normal control group. The incidence of previous heavy babies was significantly higher in the IGT group when compared with the control while that of GDM was significantly much higher. The GDM group was found to have significantly higher mean levels of fasting blood plasma glucose sugar than that of the IGT and the control groups. It was found that the serum cholestrol mean level and the serum triglycerides mean level of the IGT and that of the GDM were significantly higher than that of the control group. Also, there were no significant differences among serum fasting insulin mean levels of the three studied groups. Results of serum anti-insulin antibodies of the three studied groups were significantly different. Results of serum cortisol of the control group in the first, second and third trimesters revealed that cortisol

    This exploratory study piloted in Brisbane, Australia, reports on findings from in-depth focus-group discussions conducted with Sudanese and Eritrean women in Brisbane. We investigated and documented their experiences and knowledge of sexual and reproductive health and contraception, and explored their views on sexuality and relationships education within the family environment of minority ethnic communities in Australia. Underpinned by a qualitative psychosocial framework, the study also involved key-informant interviews with health and multicultural not-for-profit sector professionals. Through the knowledge and experiences shared by the participants, the key themes of cultural insensitivity, exclusion and poor communication within the family were highlighted by participants as determining factors in the achievement of sexual and reproductive health and good quality sex and relationships education. Participants proposed recommendations for how minority ethnic communities in Australia can more effectively support and communicate within the family environment to increase their own and their children's knowledge and understanding.

    Background:Recent studies indicate an independent association of apolipoprotein(a) small phenotypes with the diabetes and the onset of coronary heart disease.Apolipoprotein(a)small phenotypes when used together with Lipoprotein(a) levels make powerful markers in assessing the actual risk of developing coronary heart disease in diabetic patients. Objectives: Evaluation of clinical and diagnostic significant of Lipoprotein(a) levels and apolipoprotein(a) small phenotypes and its relation to coronary heart disease in Sudanese diabetic patients. Setting and duration of study: Diabetic patients attending hospitals and medical centers from May 2011-December 2012, in Khartoum, Sudan. Patients and Methods: This was a case control, hospital based study done on 138 Sudanese diabetic patients attending hospitals and medical centers in Khartoum. Patients were divided into 2 groups. One group had diabetic cases with coronary heart disease and the other were diabetic patients without coronary heart disease. Controls were age and gender matched. Blood samples were collected from both groups(patients and controls) and were run for apolipoproteins, lipoproteins and apolipoprotein(a) small phenotype,low-density lipoprotein,high-density lipoprotein and trigeminal ganglia. Results: The levels of Lipoprotein(a) of patients were significantly higher than controls (p<0.05). Apolipoprotein(a)small phenotype distribution showed a significant difference when compared between patients of both groups (diabetics with and without coronary heart disease) and controls (p<0.05). Both low-density lipoprotein and high-density lipoprotein cholesterol showed significant difference in both patient groups and controls (p<0.05). Total cholesterol and triglyceride levels showed no significant difference between patients and controls. Apolipoprotein(a) small phenotypes showed significant distribution in diabetic patients when compared with coronary heart disease patients (more than one low molecular weight

    Some traditional Chinese medicinal seeds and fruits are well known for their antioxidant properties. This research aims to investigate whether Fructus Lycii, Fructus Schisandrae Chinensis, Fructus Ligustri Lucidi and Semen Cuscutae protect DNA from oxidant challenge by hydrogen peroxide (H(2)O(2)). The standard comet assay was used to assess the genoprotective effect of these medicinal herbs. Blood was taken from three healthy adults, aged from 36 to 42. Lymphocytes were isolated and treated with different concentrations of aqueous herbal extracts, while controls were treated with phosphate buffered saline. The lymphocytes were stressed with 50 μM H(2)O(2). Treated cells were embedded in agarose and layered on slides. These sandwiched lymphocytes were lysed and afterwards subjected to an electric field in an alkaline environment. Damaged DNA was pulled out from the nucleus towards the positive electrode as a comet tail; its density was related to the degree of DNA damage. Finally, the slides were stained with fluorescence dye and tails were visually scored for 100 cells. The experiment was repeated three times and DNA damage in treated cells was compared to the controls. There was no statistical difference in DNA damage among the herb treated cells and untreated cells in the comet assay. Our data demonstrated that the selected medicinal herbs did not show in vitro DNA protection in the comet assay against oxidant challenge.

    The natural levels of 226 Ra in plant and soil samples have been studied. The field study was mainly conducted in western Sudan (Darfur and Kurdofan) where areas of high natural background radiation have been identified and Khartoum area was taken as a control to (i) assess in natural setting the soil-to-plant concentration ratios (concentration in dry sample / concentration in dry soil) of the naturally occurring radionuclide 226 Ra, (ii) establish base-line data on Radium activity concentration levels in environmental materials and (iii) explore the area of high natural radiation background in western Sudan.Low level gamma spectrometry, employing high purity germanium detector (HPGe) of relative efficiency 12%, has been used for the determination of 226 Ra activity concentrations in plant and soil samples. The mean Radium activity concentration found in soil ranged from 14.41 Bq/Kg to 79.08 Bq/Kg, the values correspond to the reported normal background levels of 226 Ra in soils worldwide. Radium activity concentrations found in Sudanese plants were significantly higher compared to those related to plants from normal background regions and significantly lower than those reported for plants from high background regions in other countries. The mean soil/plant concentration ratios (CRs) found in this study were 0.12, 0.15, 0.17 and 0.08 for whole plants, fruits and leafy vegetables, root vegetables and grains, respectively. These ranges of CR values are comparable with overall range of CR where environmental conditions are normal. The estimated daily intakes by individuals consuming foods of local origin were 1.00, 10.4 and 7.91 Bq/Day of radium Khour Abu Habil, Arkuri and Dumpir, respectively. Since the dietary habits were different, as it was noticed, these results have been much lower in comparison with those obtained from some European countries and United States.

    Thyroid diseases comprise a major health problem in Sudan. Although clinical diagnosis of thyroid diseases often easy, there are many diagnostic difficulties. So, laboratory investigations are essential in certain conditions. 97 Sudanese subjects were included in this study. According to the clinical features, patients were divided into three groups, either hyper or hypothyroid, and the control group. Laboratory diagnosis of these individuals was established in the diagnostic and research laboratory centre in Khartoum teaching hospital. The thyroid hormones studied are T 3 , T 4 , FT 4 (by enzyme immunoassay) and TSH (by the ultrasensitive enzyme immunoassay). Serum T 3 concentration was found to be high in 66% of the hyperthyroid patients, and low in 75% of the hypothyroid patients, and normal in 66.7% of the control group. Serum T 4 concentration was normal in one-third of the hyperthyroid patients, and one-fourth of the hypothyroid patients, and 90.9% of the control group. FT 4 was normal in the control group, low in 95% for the hypothyroid patients, and high in 66% of the hyperthyroid patients. Signs of hyperthyroidism were associated with high hormonal levels more than symptoms do. Hyperkinesis and eye signs had a significant correlation with the hormonal levels. No significant correlation was found between symptoms and signs of hypothyroidism and hormonal levels. So, clinical evaluation of patients is very important before assessing the laboratory values, and the free T 4 is more specific in the diagnosis of thyroid diseases. (Author)

    Thai/Lanna region has its own folklore wisdoms including the traditional medicinal plant recipes. Thai/Lanna medicinal plant recipe database "MANOSROI III" has been developed by Prof. Dr. Jiradej Manosroi. It consists of over 200,000 recipes for all diseases including cancer. To investigate the anti-proliferative and apoptotic activities on human colon cancer cell line (HT-29) as well as the cancer cell selectivity of the methanolic extracts (MEs) and fractions of the 23 selected plants from the "MANOSROI III" database. The 23 selected plants were extracted with methanol under reflux and evaluated for their anti-proliferative activity by sulforhodamine B assay. The 5 plants (Gloriosa superba, Caesalpinia sappan, Fibraurea tinctoria, Ventilago denticulata and Psophocarpus tetragonolobus) with potent anti-proliferative activity were fractionated by liquid-liquid partition to give 4 fractions including each hexane (HF), methanol-water (MF), n-butanol (BF) and water (WF) fractions. They were tested for anti-proliferative activity and cancer cell selectivity. The ME and fractions of G. superba which showed potent anti-proliferative activity were further examined for morphological changes and apoptotic activities by acridine orange (AO)/ethidium bromide (EB) staining. The ME of G. superba root showed active with the highest anti-proliferative activity at 9.17 and 1.58 folds of cisplatin and doxorubicin, respectively. After liquid-liquid partition, HF of V. denticulata, MFs of F. tinctoria, V. denticulata and BF of P. tetragonolobus showed higher anti-proliferative activities than their MEs. The MF of G. superba indicated the highest anti-proliferative activity at 7.73 and 1.34 folds of cisplatin and doxorubicin, respectively, but only 0.86 fold of its ME. The ME and HF, MF and BF of G. superba and MF of F. tinctoria demonstrated high cancer cell selectivity. At 50 µg/ml, ME, HF, MF and BF of G. superba demonstrated higher apoptotic activities than the two standard drugs

    The study was conducted in Saudi Arabia to assess the nutritional status of primary school Sudanese pupils and explore its' correlates. Anthropometric measurements of 400 (200 males and 200 females) students of age 6-12 were taken. Their daily food intake was assessed using food frequency and 24 h recall method. Data about the socio-economic characteristics of the students' families was collected through personal interview using a questionnaire. The study revealed that 31 and 8.75 % of the respondents suffer from underweight and overweight, respectively. The respondents' average daily intake of calories and fiber was significantly lower than that of the DRI, while their intake of protein, carbohydrates, unsaturated fat, some vitamins and iron was significantly higher than that of the DRI (unbalanced meals). Apart from the family monthly income none of the hypothesized predictors of the respondents' nutritional status were found to be significantly correlated with the students' nutritional status indicators.

    This paper explores the impact of pre-migration trauma, post-migration living difficulties and social support on the current mental health of 63 resettled Sudanese refugees. A semistructured interview including questionnaires assessing sociodemographic information, pre-migration trauma, anxiety, depression and posttraumatic stress, post-migration living difficulties and perceived social support were administered assisted by a bilingual community worker. Resettled refugees from Sudan evidenced a history of trauma. Less than 5% met criteria for posttraumatic stress but 25% reported clinically high levels of psychological distress. The results indicate that social support--particularly perceived social support from the migrant's ethnic community--play a significant role in predicting mental health outcomes. Pre-migration trauma, family status and gender were also associated with mental health outcomes. Refugees in Australia may constitute a particularly vulnerable group in terms of mental health outcomes. Culturally specific sequelae in terms of social isolation and acculturation may be particularly problematic for these migrants.

    Full Text Available Abstract: The goals and means of language study continue in the very center of debates among specialists in language teaching/learning. Different views relating to language and its functions are reflected in two main approaches to language teaching/learning. On the one hand, language is considered to be principally instrumental, a means of communicating thought and information. One the other hand, language is viewed as an important element of human being’s thought processes, perceptions, and self-expressions; and as such, it is placed at the core of translingual and transcultural competence. This paper investigates the current situation of teaching/learning foreign languages in the Sudanese universities with special focus on the goals of teaching these languages and their role in students’ future. Goals of language teaching and students’ attitudes towards the process will be related to the job opportunities available for the students on graduation. Data for the paper have been collected using questionnaires and interviews administered to students and teachers from five language departments at Khartoum University: English, French, German, Russian, and Chinese. Questionnaires and interviews on language attitude will be administered among Four-year language majors representing the four departments. The central question the paper tries to answer is whether there is a realistic match between the goals of language teaching/learning set by policy makers and students’ interests and expectations. Results are expected to contribute to the efforts made to restructure language-in-education curriculum at university level in a way that addresses the expectations of both policy makers and students. Keywords: Foreign language teaching and learning, goals, attitude.

    In low- and middle-income countries, patients and reimbursement agencies that purchase medicines in the private sector pay more for originator brands when generic equivalents exist. We estimated the savings that could be obtained from a hypothetical switch in medicine consumption from originator brands to lowest-priced generic equivalents for a selection of medicines in 17 countries. In this cost minimization analysis, the prices of originator brands and their lowest-priced generic equivalents were obtained from facility-based surveys conducted by using a standard methodology. Fourteen medicines most commonly included in the surveys, plus three statins, were included in the analysis. For each medicine, the volume of private sector consumption of the originator brand product was obtained from IMS Health, Inc. Volumes were applied to the median unit prices for both originator brands and their lowest-priced generics to estimate cost savings. Prices were adjusted to 2008 by using consumer price index data and were adjusted for purchasing power parity. For the medicines studied, an average of 9% to 89% could be saved by an individual country from a switch in private sector purchases from originator brands to lowest-priced generics. In public hospitals in China, US $ 370 million could be saved from switching only four medicines, saving an average of 65%. Across individual medicines, average potential savings ranged from 11% for beclometasone inhaler to 73% for ceftriaxone injection. Substantial savings could be achieved by switching private sector purchases from originator brand medicines to lowest-priced generic equivalents. Strategies to promote generic uptake, such as generic substitution by pharmacists and increasing confidence in generics by professionals and the public, should be included in national medicines policies.

    This study was conducted during the period from 15/01/04 to 24/04/04 at Sudan Fertility Care Association Center. Sixty nine Sudanese females using combined oral contraceptives were chosen for this study and twenty females not using contraceptives were used as controls. All individuals were within the same age group. Thyroid hormones; thyroxine (T 4 ), triiodothyronine (T 3 ), free thyroxine (FT 4 ) and free triiodothyronine (FT 3 ) were measured. In addition thyroid stimulating hormone (TSH) was also measured in both groups. The study groups were divided according to the period of using combined oral contraceptives into four groups group 1 (1-5) months, group 2 (7-16) months and group 3 (18-60) months and the control group of the non users. Determination of hormones concentrations were carried out using a highly sensitive specific radioimmunoassay (RIA) technique. The concentrations of serum T 4 in group 3 was significantly higher (P 4 in group 1 and 2 were found to be lower than in the control and the difference was not significant. Mean serum concentration of triiodothyronine in the study group 1, 2 and 3 were not significantly higher than the control group. Mean serum concentration of free triiodothyronine in the study groups 1, 2 and 3 were not significantly higher than the control group. Mean serum concentration of free thyroxine in the study group 1, 2 and 3 were not significantly higher than the control group. Mean serum concentration of TSH in groups 1, 2 and 3 were significantly (P<0.05) lower than in the control group.(Author)

    2009-02-01

    Medical students have had a declining interest in family medicine as a career. Some studies have shown a small inverse relationship between debt levels and primary care, but it is unclear how students perceive remuneration in different specialties and how these perceptions might influence career choice. Medical students at one school were surveyed to understand their perceptions of physician remuneration and to gain insight into how these perceptions might affect career selection. Response rate was 72% (560/781 students). Students' estimates of physician income were accurate throughout training, with the overall estimate for family medicine being lower than the actual income by only $10,656. The vast majority of students agreed with the statement that family physicians get paid too little (85%-89% of each class). The importance of payment as a factor in career decision making increased with higher debt and with advancing training. Students are able to accurately predict income by specialty from an early stage of training and have a negative perception of income in family medicine. The perception that family physicians make too little money could be an important driver--or at least a modifier--in the lack of interest in family medicine.

    The access to essential medicines for non-communicable disease treatment is unacceptably low worldwide. The fundamental right to health cannot be fulfilled without equitable access to essential medicines. A cross-sectional study was carried out in 94 community pharmacies of Kathmandu valley. Non-probability quota sampling method was adopted for the purpose. Village Development Committees with more than 5000 populations were included in the study. The availability of the selected essential medicines, their price and producer identity were observed. Data entry and analysis were carried out in Microsoft Excel and Statistical package for social science. The availability of the essential medicines was not 100% in Kathmandu valley. High competition and high price variation were seen in metformin 500 mg (254.6%) and atorvastatin 10 mg (327.6%). The study showed that maximum (54.7%) brands were manufactured in Nepal. Furthermore, atorvastatin 10 mg (0.6 day wage) was found to be quite expensive, and glibenclamide 5 mg (0.1 day wage) was the cheapest one for diabetes mellitus treatment for 1 month of treatment period compared to daily wages of other essential medicines. The availability of the selected essential medicines was found to be ununiform and insufficient in the entire region. High competition was observed in the products with high price variation, and the access to cost-effective brand was poor. Furthermore, it was found that government salary is affordable to treat non-communicable disease with the help of the essential medicines.

    Targeting epigenetic proteins is a rapidly growing area for medicinal chemistry and drug discovery. Recent years have seen an explosion of interest in developing small molecules binding to bromodomains, the readers of acetyl-lysine modifications. A plethora of co-crystal structures has motivated focused fragment-based design and optimization programs within both industry and academia. These efforts have yielded several compounds entering the clinic, and many more are increasingly being used as chemical probes to interrogate bromodomain biology. High selectivity of chemical probes is necessary to ensure biological activity is due to an on-target effect. Here, we review the state-of-the-art of bromodomain-targeting compounds, focusing on the structural basis for their on-target selectivity or lack thereof. We also highlight chemical biology approaches to enhance on-target selectivity.

    This work was examined whether intradermal immunization of healthy adult Sudanese volunteers with killed leishmania major (KLM) promastigotes plus BCG would induce antigen-specific T cell responses. Only healthy Sudanese volunteers with negative reactivity to leishmania skin test and with ≤20 mm induration of reactivity to purified protein derivative (PPD) were included in the trial. Group (A) (n=3): received a single dose (0.1ml) at a concentration of 10 mg protein of a whole cell component of KLM promastigotes/ml BCG, group (B) (n=12): received as a single dose of viable attenuated BCG alone (0.1 ml) at a concentration of 1 mg protein/ml diluent, group (C) (n=11): received the vaccine diluent only (Placebo) (o.1 ml). Study subjects were tested for their immunological and clinical responses before intervention, . Following vaccination 65% of group (A) subjects converted in their reactivity to leishmanin skin testing,non of the BCG vaccinated subjects converted in leishmanin skin test and only one subject of group (C) became leishmanin positive. Levels of Interferon-gamma (IFN-γ), interleukin-5 (IL-5) and interleukin-10 (IL-10) were measured by a double sandwich enzyme-linked immunosorbent assay (ELISA). A vaccine was considered as a positive responder in terms of cytokine production when the level of the produced cytokine was equal to the 80th percentile of the levels produced by the volunteers in the placebo group. 92% of the group vaccinated with KLM=BCG had circulating T cells. No significant of IL-5 or Il-10 was reported in any of the volunteers in the three group. Levels of anti l eishmania specific IgG were measured by ELISA in optical densities. Volunteers with mean antibody titre above the cut-off point (mean=3X standard deviation) were considered to have positive scores. Accordingly after vaccination 7.69% one volunteers in group (A) had a positive antibody response corresponding to 0% in the other two groups. No serious side effects were reported

    Cancer has been extensively characterized on the basis of genomics. The integration of genetic information about cancers with data on how the cancers respond to target based therapy to help to optimum cancer treatment. The increasing usage of sequencing technology in cancer research and clinical practice has enormously advanced our understanding of cancer mechanisms. The cancer precision medicine is becoming a reality. Although off-label drug usage is a common practice in treating cancer, it suffers from the lack of knowledge base for proper cancer drug selections. This eminent need has become even more apparent considering the upcoming genomics data. In this paper, a personalized medicine knowledge base is constructed by integrating various cancer drugs, drug-target database, and knowledge sources for the proper cancer drugs and their target selections. Based on the knowledge base, a bioinformatics approach for cancer drugs selection in precision medicine is developed. It integrates personal molecular profile data, including copy number variation, mutation, and gene expression. By analyzing the 85 triple negative breast cancer (TNBC) patient data in the Cancer Genome Altar, we have shown that 71.7% of the TNBC patients have FDA approved drug targets, and 51.7% of the patients have more than one drug target. Sixty-five drug targets are identified as TNBC treatment targets and 85 candidate drugs are recommended. Many existing TNBC candidate targets, such as Poly (ADP-Ribose) Polymerase 1 (PARP1), Cell division protein kinase 6 (CDK6), epidermal growth factor receptor, etc., were identified. On the other hand, we found some additional targets that are not yet fully investigated in the TNBC, such as Gamma-Glutamyl Hydrolase (GGH), Thymidylate Synthetase (TYMS), Protein Tyrosine Kinase 6 (PTK6), Topoisomerase (DNA) I, Mitochondrial (TOP1MT), Smoothened, Frizzled Class Receptor (SMO), etc. Our additional analysis of target and drug selection strategy is also fully

    As many as 229 medicinal plants have been currently used in the Bhutanese Traditional Medicine (BTM) as a chief ingredient of polyherbal formulations and these plants have been individually indicated for treating various types of infections including malaria, tumor, and microbial. We have focused our study only on seven species of these plants. We aim to evaluate the antiplasmodial, antimicrobial, anti-Trypanosoma brucei rhodesiense and cytotoxicity activities of the seven medicinal plants of Bhutan selected using an ethno-directed bio-rational approach. This study creates a scientific basis for their use in the BTM and gives foundation for further phytochemical and biological evaluations which can result in the discovery of new drug lead compounds. A three stage process was conducted which consisted of: (1) an assessment of a pharmacopoeia and a formulary book of the BTM for their mode of plant uses; (2) selecting 25 anti-infective medicinal plants based on the five established criteria, collecting them, and screening for their major classes of phytochemicals using appropriate test protocols; and (3) finally analyzing the crude extracts of the seven medicinal plants, using the standard test protocols, for their antiplasmodial, antimicrobial, anti-Trypanosoma brucei rhodesiense and cytotoxicity activities as directed by the ethnopharmacological uses of each plant. Out of 25 medicinal plants screened for their major classes of phytochemicals, the majority contained tannins, alkaloids and flavonoids. Out of the seven plant species investigated for their biological activities, all seven of them exhibited mild antimicrobial properties, five plants gave significant in vitro antiplasmodial activities, two plants gave moderate anti-Trypanosoma brucei rhodesiense activity, and one plant showed mild cytotoxicity. Meconopsis simplicifolia showed the highest antiplasmodial activity with IC(50) values of 0.40 μg/ml against TM4/8.2 strain (a wild type chloroquine and

    A sulfur-functionalized aminoacrolein derivative is used for the efficient and selective synthesis of heterocyclic sulfonyl chlorides, sulfonyl fluorides, and sulfonamides. The development of a 3-step parallel medicinal chemistry (PMC) protocol for the synthesis of pyrazole-4-sulfonamides effectively demonstrates the utility of this reagent. This reactivity was expanded to provide rapid access to other heterocyclic sulfonyl fluorides, including pyrimidines and pyridines, whose corresponding sulfonyl chlorides lack suitable chemical stability.

    In our country general internists are the providers of adult medical care in urban areas. In the past twenty years, with the increasing subspecialization within internal medicine and the development of advances in technology, the role of the general internist seems to be endangered. Recently much attention has been focused on this area and Divisions and Programs of General Internal Medicine have been established in most medical schools in the USA. The University of Buenos Aires instituted a Program of General Internal Medicine in its major teaching hospital in 1987. One of its purposes was to offer an educational experience to residents in the field of internal medicine primary care. This paper summarizes how this program was carried out and the subjects proposed in the area of Diagnosis and Treatment. The Program of General Internal Medicine is performed in the Outpatient Division and it is staffed by 3 faculty members and 4 fellows. Residents in Internal Medicine have a three month, full-time block rotation in the Program. A young, city dwelling, lower middle class population participates in the Program, with almost 10000 visits a year. The Program offers an experience that includes supervised patient care, an average of 100 office visits a month, and seminars and/or workshops covering topics of "Diagnosis and Treatment", "Case Presentations", "Clinical Epidemiology", "Prevention", and "Doctor-Patient Interview". In the area of Diagnosis and Treatment, the criteria used were: 1-frequency of diagnosis as determined by previous investigations, 2-relevant clinical conditions absent from the frequency list as determined by a consensus process by faculty members.(ABSTRACT TRUNCATED AT 250 WORDS)

    The Multiple Mini-Interview (MMI) uses multiple, short-structured contacts to evaluate communication and professionalism. It predicts medical school success better than the traditional interview and application. Its acceptability and utility in emergency medicine (EM) residency selection are unknown. We theorized that participants would judge the MMI equal to a traditional unstructured interview and it would provide new information for candidate assessment. Seventy-one interns from 3 programs in the first month of training completed an eight-station MMI focused on EM topics. Pre- and post-surveys assessed reactions. MMI scores were compared with application data. EM grades correlated with MMI performance (F[1, 66] = 4.18; p interview (mean difference = 1.36; p interview and MMI) was preferred over a MMI alone (mean difference = 1.1; p interview, participants were receptive to a mixed-methods interview. The MMI does correlate with performance on the EM clerkship and therefore can measure important abilities for EM success. Future work will determine whether MMI performance predicts residency performance. Copyright © 2014 Elsevier Inc. All rights reserved.

    The incomplete identification of the chemical components of traditional Chinese medicinal formula has been one of the bottlenecks in the modernization of traditional Chinese medicine. Tandem mass spectrometry has been widely used for the identification of chemical substances. Current automatic tandem mass spectrometry acquisition, where precursor ions were selected according to their signal intensity, encounters a drawback in chemical substances identification when samples contain many overlapping signals. Compounds in minor or trace amounts could not be identified because most tandem mass spectrometry information was lost. Herein, a molecular feature orientated precursor ion selection and tandem mass spectrometry structure elucidation method for complex Chinese medicine chemical constituent analysis was developed. The precursor ions were selected according to their two-dimensional characteristics of retention times and mass-to-charge ratio ranges from herbal compounds, so that all precursor ions from herbal compounds were included and more minor chemical constituents in Chinese medicine were identified. Compared to the conventional automatic tandem mass spectrometry setups, the approach is novel and can overcome the drawback for chemical substances identification. As an example, 276 compounds from the Chinese Medicine of Yi-Xin-Shu capsule were identified. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    A soil-to-plant transfer factor (TF) is an important parameter that could be used to estimate radionuclides levels in medicinal plants. This work reports concentrations of natural radionuclides ( 226 Ra and 40 K) and TFs in six Thai medicinal plants grown in central Thailand using an HPGe gamma ray spectrometer. Either root, leaf, or flower parts of each medicinal plant were selected for use in the investigation according to their practical uses in traditional medicine. The results showed that due to K being essential in plants, 40 K had higher arithmetic means of activity concentrations and geometric means of TFs (geometric standard deviations in parentheses) of 610 ± 260 Bq kg -1 dry weight (DW) and 2.0 (1.4), respectively, than 226 Ra, which had the activity concentrations and TFs of 4.8 ± 2.6 Bq kg -1 DW and 0.17 (1.8), respectively. The results also showed that the leaves of medicinal plants had higher activity concentrations and TFs than root and flower parts, probably due to higher metabolic activities in leaves. Furthermore, there was good agreement between the results from the current work and other similar reports on medicinal plants. The information obtained from this work could strengthen knowledge of natural radionuclides in plants and particularly increase available TF data on Thai medicinal plants.

    Thai/Lanna medicinal plant recipes have been used for the treatment of several diseases including oral and cervical cancers. To investigate anti-proliferative activity on human cervical (HeLa) and oral (KB) cancer cell lines of medicinal plants selected from Thai/Lanna medicinal plant recipe database "MANOSROI III". Twenty-three methanolic plant crude extracts were tested for phytochemicals and anti-proliferative activity on HeLa and KB cell lines for 24 h by the sulforhodamine B (SRB) assay at the doses of 1 × 10(1)-1 × 10(-6 )mg/ml. The nine extracts with the concentrations giving 50% growth inhibition (GI50) lower than 100 µg/ml were further semi-purified by liquid/liquid partition in order to evaluate and enhance the anti-proliferative potency. All extracts contained steroids/triterpenoids, but not xanthones. The methanolic extracts of Gloriosa superba L. (Colchinaceae) root and Albizia chinensis (Osbeck) Merr. (Leguminosae-Mimosoideae) wood gave the highest anti-proliferative activity on HeLa and KB cell lines with the GI50 values of 0.91 (6.0- and 0.31-fold of cisplatin and doxorubicin) and 0.16 µg/ml (28.78- and 82.29-fold of cisplatin and doxorubicin), respectively. Hexane and methanol-water fractions of G. superba exhibited the highest anti-proliferative activity on HeLa and KB cell lines with the GI50 values of 0.15 (37- and 1.9-fold of cisplatin and doxorubicin) and 0.058 µg/ml (77.45- and 221.46-fold of cisplatin and doxorubicin), respectively. This study has demonstrated the potential of plants selected from MANOSROI III database especially G. superba and A. chinensis for further development as anti-oral and cervical cancer agents.

    Panax L. (the ginseng genus) is a shade-demanding group within the family Araliaceae and all of its species are of crucial significance in traditional Chinese medicine. Phylogenetic and biogeographic analyses demonstrated that two rounds of whole genome duplications accompanying with geographic and ecological isolations promoted the diversification of Panax species. However, contributions of the cytoplasmic genomes to the adaptive evolution of Panax species remained largely uninvestigated. In this study, we sequenced the chloroplast and mitochondrial genomes of 11 accessions belonging to seven Panax species. Our results show that heterogeneity in nucleotide substitution rate is abundant in both of the two cytoplasmic genomes, with the mitochondrial genome possessing more variants at the total level but the chloroplast showing higher sequence polymorphisms at the genic regions. Genome-wide scanning of positive selection identified five and 12 genes from the chloroplast and mitochondrial genomes, respectively. Functional analyses further revealed that these selected genes play important roles in plant development, cellular metabolism and adaptation. We therefore conclude that positive selection might be one of the potential evolutionary forces that shaped nucleotide variation pattern of these Panax species. In particular, the mitochondrial genes evolved under stronger selective pressure compared to the chloroplast genes.

    Evolution has long provided a foundation for population genetics, but many major advances in evolutionary biology from the 20th century are only now being applied in molecular medicine. They include the distinction between proximate and evolutionary explanations, kin selection, evolutionary models for cooperation, and new strategies for tracing phylogenies and identifying signals of selection. Recent advances in genomics are further transforming evolutionary biology and creating yet more opportunities for progress at the interface of evolution with genetics, medicine, and public health. This article reviews 15 evolutionary principles and their applications in molecular medicine in hopes that readers will use them and others to speed the development of evolutionary molecular medicine.

    HR-HPV subtypes are strongly linked to etiology of many human cancers including oral cancer. The epidemiology of infection with different HPV genotypes greatly varies in different countries. The aim of this study was to identify and genotype the HR-HPV subtypes in oral tissues obtained from Sudanese patients with oral lesions. In this retrospective study 200 patients with oral lesions were screened by molecular methods (PCR) for the presence of HR-HPV subtypes. Of the 200 patients, 100/200 were patients with oral cancer (ascertained as case group) and 100/200 were patients with non-neoplastic oral lesions (ascertained as control group). Out of the 200 patients, 12/200 (6%) were found with HR-HPV infection. Of the 12 positive patients, 8/12 (66.7%) were among cases and the remaining 4/12 (33.3%) were among control group. The distribution of different genotypes was: type HPV 16 6/12 (50%), HPV18 4/12 (34%), HPV 31 1/12 (8%) and HPV 33 1/12 (8%). In view of these findings, HPV particularly subtypes 16 and 18 play a role in the etiology of oral cancer in the Sudan.

    Full Text Available Abstract Background Prenatal use of traditional medicine or complementary and alternative medicine is widespread globally despite the lack of evidence of the effectiveness of these therapeutic options. Documentation on the prevalence and patterns of this maternal practice in the Zimbabwean setting was also lacking. Methods A cross sectional survey of 248 women at selected health centres in Harare was carried out to address the need for such data using an interviewer-administered questionnaire. Results Fifty-two (52% (95% C.I. 44%-60% of the participants reported to have used at least one traditional medicine intervention during the third trimester of their most recent pregnancy to induce labour, avoid perineal tearing and improve the safety of their delivery process. The study found prenatal use of traditional medicine to be significantly associated with nulliparity and nulligravidity. Such practice was also significant among participants residing in a particular high density suburb located in close proximity to informal traders of traditional medicines. Prenatal traditional medicine use was not significantly linked to experiencing an obstetrics-related adverse event. Instead, participants who reported not using any traditional medicine during pregnancy reported experiencing significantly more adverse events, mainly perineal tearing during delivery. Conclusions The practice of prenatal use of traditional medicine was significant in the study setting, with a prevalence of 52%. A variety of products were used in various dosage forms for differing indications. Nulliparity, nulligavidity and possible accessibility of these products were the factors significantly associated with prenatal use of traditional medicine. Prenatal use of traditional medicine was not significantly associated with any obstetric adverse event.

    Full Text Available Topical medicinal patches have been popular for the treatment of minor injuries like sprains and avulsions. Other inflammatory conditions like chronic musculo-tendinous pain and or fasciitis are also taken care of by local ointments or rubs. In the oriental communities, medicinal herbs frequently form the major components of the patches.In spite of the lack of scientific evidence of efficacy, the popularity of such traditional application persists for centuries.In this era of evidence-based clinical treatment, there is an urgent need to look into this traditional practice. The purpose should include a scientific verification of the efficacy of the practice, and once proven, further explorations would be indicated to bring the practice to a higher level.A system of comprehensive exploration was proposed and practiced in the past years to fulfill the aspiration. The research consisted of four areas:(1Identification of the suitable medicinal herbs for the topical study;(2Study of the biological activities of the selected herbs, concentrating on the areas of anti-inflammation, anti-oxidation, angiogenesis and cellular proliferation;(3Study on the transcutaneous transport of the chemicals of the selected herbs to deeper tissues; and(4Pilot clinical studies on common superficial inflammatory musculo-skeletal conditions to give objective clinical evidences to the topical applications.Five herbs were identified as suitable candidates of study. They were put into relevant laboratory platforms and were proven to be anti-oxidant, anti-inflammatory and pro-angiogenic. Three of the herbs were prepared as topical patches with an enhancer and used to treat three common ailments in pilot clinical trials, viz., plantar fasciitis, undisplaced metatarsal fracture and tendonitis of the wrist (de-Quervain’s disease and the elbow (Tennis elbow. The clinical results of the pilot studies were very positive.It is therefore concluded that further explorations are

    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 In this research work, the antioxidant and metabolomic profiling of seven selected medicinally important herbs including Rauvolfia serpentina, Terminalia arjuna, Coriandrum sativum, Elettaria cardamom, Piper nigrum, Allium sativum, and Crataegus oxyacantha was performed. The in vivo cardioprotective potential of these medicinal plants was evaluated against surgically induced oxidative stress through left anterior descending coronary artery ligation (LADCA in dogs. The antioxidant profiling of these plants was done through DPPH and DNA protection assay. The C. oxyacantha and T. arjuna showed maximum antioxidant potential, while the E. cardamom showed poor antioxidative strength even at its high concentration. Different concentrations of extracts of the said plants exhibited the protection of plasmid DNA against H2O2 damage as compared to the plasmid DNA merely treated with H2O2. The metabolomic profiling through LC-MS analysis of these antioxidants revealed the presence of active secondary metabolites responsible for their antioxidant potential. During in vivo analysis, blood samples of all treatment groups were drawn at different time intervals to analyze the cardiac and hemodynamic parameters. The results depicted that the group pretreated with HC4 significantly sustained the level of CK-MB, SGOT, and LDH as well as hemodynamic parameters near to normal. The histopathological examination also confirmed the cardioprotective potential of HC4. Thus, the HC4 being safe and inexpensive cardioprotective herbal combination could be considered as an alternate of synthetic drugs.

The results depicted that the group pretreated with HC4 significantly sustained the level of CK-MB, SGOT, and LDH as well as hemodynamic parameters near to normal. The histopathological examination also confirmed the cardioprotective potential of HC4. Thus, the HC4 being safe and inexpensive cardioprotective herbal combination could be considered as an alternate of synthetic drugs. PMID:29576858

    In the present study, the concentrations of Co, Cr, Fe, Hg, Rb, Se, Zn in the serum of 103 adult patients with newly diagnosed of leukemia (before treatment) were studied. Samples were collected from Radiation of Isotopes Center-Khartoum (RICK) and Institute of Nuclear Medicine and Molecular Biology-Aljazeera State. Samples were freeze-dried and analyzed using Neutron Activation Analysis (NAA). Serum levels of these elements were compared with the contents found in healthy group samples. The patients were divided into 4 groups: 1- Acute Lymphoid Leukemia (ALL), 2- Acute Myeloid Leukemia (AML), 3- Chronic Lymphoid Leukemia (CLL), 4- Chronic Myeloid Leukemia (CML). The control group was formed of 40 healthy subjects, data analysis was performed using the T-tests. partial correlation was used to study a relationship between two variables. It was found that, In group I (ALL): higher concentration of Cr, Fe, Hg, Rb, Zn, were found in the serum of patients with significant difference as compared to healthy group (p < 0.05). The concentration of Co was higher than the control group but statistically not significant. The level of selenium was considerably lower than in the control group (p < 0.05). In group II (AML): Significantly elevated values were found in Cr and Fe as compared to the control group. The concentrations of Co, Hg and Zn also were higher but statistically not significant (p> 0.05), the level of selenium was statistically lower than in the control group (p< 0.05). In group III (CLL): It was observed that contents of the Cr, Fe, Hg, Rb, Zn elements were elevated significantly (p<0.05) than healthy subjects. The concentration of Co was higher than the control group but statistically not significant, the level of selenium was considerably lower than in the control group (p < 0.05). In group 4 (CML): The concentrations of Fe, Hg, Rb, Zn were statistically higher than in the healthy subject (p < 0.05). Also the level of Cr was higher but statistically not

    The purpose of this study was to investigate the quality of a select group of medicines sold in accredited drug dispensing outlets (ADDOs) and pharmacies in different regions of Tanzania as part of an in-depth cross-sectional assessment of community access to medicines and community use of medicines. We collected 242 samples of amoxicillin trihydrate, artemether-lumefantrine (ALu), co-trimoxazole, ergometrine maleate, paracetamol, and quinine from selected ADDOs and pharmacies in Mbeya, Morogoro, Singida, and Tanga regions. The analysis included physical examination and testing with validated analytical techniques. Assays for eight of nine products were conducted using high-performance thin-layer chromatography (HPTLC). For ALu tablets, we used a two-tiered approach, where tier 1 was a semi-quantitative Global Pharma Health Fund-Minilab® method and tier 2 was high-performance liquid chromatography (HPLC) as described in The International Pharmacopoeia's monograph for artemether-lumefantrine. The physical examination of samples revealed no defects in the solid and oral liquid dosage forms, but unusual discoloration in an injectable solution, ergometrine maleate. For ALu, the results showed that of 38 samples, 31 (81.6%) passed tier 1 testing and 7 (18.4%) gave inconclusive drug content results. The inconclusive ALu samples were submitted for tier 2 testing and all met the quality standards. The pass rate using the HPTLC and TLC/HPLC assays was 93.8%; the failures were the ergometrine maleate samples purchased from both ADDOs and pharmacies. The disintegration testing of the solid dosage forms was conducted in accordance with US Pharmacopeia monographs. Only two samples of paracetamol, 1.2% of the solid dosage forms, failed to comply to standards. The study revealed a high overall rate of 92.6% of samples that met the quality standards. Although the overall failure rate was 7.4%, it is important to note that this was largely limited to one product and likely due to

    Holistic veterinary medicine treats the whole patient including all physical and behavioral signs. The root cause of disease is treated at the same time as accompanying clinical signs. Herbal and nutritional supplements can help support tissue healing and proper organ functioning, thereby reducing the tendency of disease progression over time. Proper selection of homeopathic remedies is based on detailed evaluation of clinical signs. Herbal medicines are selected based on organ(s) affected and the physiologic nature of the imbalance. Many herbal and nutraceutical companies provide support for veterinarians, assisting with proper formula selection, dosing, drug interactions, and contraindications. Copyright © 2014 Elsevier Inc.

    2015-12-01

    Full Text Available This article presents our analysis of Australian media reporting of the 2006 Tamworth City Council’s decision to refuse the resettlement of five Sudanese families in Tamworth (NSW and subsequent reversal, supposedly due to the pressure brought to bear on the council as a result of the media “hype.” The question at the core of our analyses is as follows: Did the media play a role in the over-(representation of this case as racist or was it just a case of the media reporting racism? Informed by media framing theory, we examine print media reports for patterns of presentation as well as representations of both the council and the refugees who were the focus of the reporting. We conclude that while the media played a significant role in making visible a case built on racial stereotypes, their reporting also contained racializing and paternalistic stereotyping that contribute to the reproduction of both everyday and systemic racism.

    Precision medicine can greatly benefit men's health by helping to prevent, diagnose, and treat prostate cancer, benign prostatic hyperplasia, infertility, hypogonadism, and erectile dysfunction. For example, precision medicine can facilitate the selection of men at high risk for prostate cancer for targeted prostate-specific antigen screening and chemoprevention administration, as well as assist in identifying men who are resistant to medical therapy for prostatic hyperplasia, who may instead require surgery. Precision medicine-trained clinicians can also let couples know whether their specific cause of infertility should be bypassed by sperm extraction and in vitro fertilization to prevent abnormalities in their offspring. Though precision medicine's role in the management of hypogonadism has yet to be defined, it could be used to identify biomarkers associated with individual patients' responses to treatment so that appropriate therapy can be prescribed. Last, precision medicine can improve erectile dysfunction treatment by identifying genetic polymorphisms that regulate response to medical therapies and by aiding in the selection of patients for further cardiovascular disease screening.

    Carr, S.W.

    1998-01-01

    Full text: Nuclear medicine occupies an important niche in the spectrum of medical capability. Since its initial application on a routine basis over 30 years ago its importance has continued to grow. For example, it is expected that over 430,000 Australians will have a nuclear medicine procedure in 1998. Current procedures using nuclear medicine are mainly concerned with diagnosis of oncology, cardiology and neurology. The main radioisotope used in nuclear medicine is Tc 99m, which is produced by a 'so called' Mo-Tc 99m generator. Other isotopes which currently find routine use are Ga-67, Th-201 and I-131. The selective uptakes by particular organs or structures is facilitated by the use of 'cold kits' which after the chemistry of the radioisotope many of the recent advances have been concerned with increasing the selectivity for a particular organ structure. Several of these new agents show increased selectivity using antibody a peptide recognition units

    Internal control genes are the constitutive genes which maintain the basic cellular functions and regularly express in both normal and stressed conditions in living organisms. They are used in normalization of gene expression studies in comparative analysis of target genes, as their expression remains comparatively unchanged in all varied conditions. Among internal control genes, actin is considered as a candidate gene for expression studies due to its vital role in shaping cytoskeleton and plant physiology. Unfortunately most of such knowledge is limited to only model plants or crops, not much is known about important medicinal plants. Therefore, we selected seven important medicinal wild plants for molecular identification of actin gene. We used gene specific primers designed from the conserved regions of several known orthologues or homologues of actin genes from other plants. The amplified products of 370-380 bp were sequenced and submitted to GeneBank after their confirmation using different bioinformatics tools. All the novel partial sequences of putative actin genes were submitted to GeneBank (Parthenium hysterophorus (KJ774023), Fagonia indica (KJ774024), Rhazya stricta (KJ774025), Whithania coagulans (KJ774026), Capparis decidua (KJ774027), Verbena officinalis (KJ774028) and Aerva javanica (KJ774029)). The comparisons of these partial sequences by Basic Local Alignment Search Tool (BLAST) and phylogenetic trees demonstrated high similarity with known actin genes of other plants. Our findings illustrated highly conserved nature of actin gene among these selected plants. These novel partial fragments of actin genes from these wild medicinal plants can be used as internal controls for future gene expression studies of these important plants after precise validations of their stable expression in such plants.

    Full Text Available Background: Uncorrected refractive error is a major cause of avoidable vision impairment and may have significant impact on social life, education and economic prospects of people. This condition could be easily treated by wearing spectacles, but because of attitudes and misconceptions of some communities towards spectacle wear and eye care, such methods are underutilised. Aim: To assess the attitudes and perceptions of Sudanese high-school students and their parents towards spectacle wear. Setting: The study was conducted in eight randomly selected high schools from the South Darfur state of Sudan. Methods: A cross-sectional school-based study comprising 387 high-school students with age ranging from 12 to 17 years together with 47 students’ parents with age ranging from 32 to 52 years. Quantitative and qualitative methods were used to collect data from eight high schools. Semi-structured questionnaires were distributed to collect the quantitative data, and seven focus group meetings were held in the schools with students’ parents to derive the qualitative data. Results: The findings revealed that 39%, 32% and 27.1% of the students believed that wearing spectacles affected their opportunities for education, employment and marriage, respectively. A total of 36.4% of the students believed that wearing spectacles could lead to making the eyes weaker or could damage the eyes, resulting in early blindness, and 22.5% of the respondents believed that spectacles were only for older people. In general, the perception towards spectacle wear was different between genders, with females appearing to be more vulnerable to social and psychological distress when wearing spectacles compared to males. A total of 79% of the parents were aware that wearing spectacles would improve vision if an eye doctor prescribed the spectacles. However, parents reported that the disadvantages of wearing spectacles were that they reduced the power of the eyes and

    In Mediterranean cultures written records of medicinal plant use have a long tradition. This written record contributed to building a consensus about what was perceived to be an efficacious pharmacopeia. Passed down through millennia, these scripts have transmitted knowledge about plant uses, with high fidelity, to scholars and laypersons alike. Herbal medicine's importance and the long-standing written record call for a better understanding of the mechanisms influencing the transmission of contemporary medicinal plant knowledge. Here we contextualize herbal medicine within evolutionary medicine and cultural evolution. Cumulative knowledge transmission is approached by estimating the causal effect of two seminal scripts about materia medica written by Dioscorides and Galen, two classical Greco-Roman physicians, on today's medicinal plant use in the Southern Italian regions of Campania, Sardinia, and Sicily. Plant-use combinations are treated as transmissible cultural traits (or “memes”), which in analogy to the biological evolution of genetic traits, are subjected to mutation and selection. Our results suggest that until today ancient scripts have exerted a strong influence on the use of herbal medicine. We conclude that the repeated empirical testing and scientific study of health care claims is guiding and shaping the selection of efficacious treatments and evidence-based herbal medicine.

    1984-01-01

    This guidebook for clinical nuclear medicine is written as a description of how nuclear medicine procedures should be used by clinicians in evaluating their patients. It is designed to assist medical students and physicians in becoming acquainted with nuclear medicine techniques for detecting and evaluating most common disorders. The material provides an introduction to, not a textbook of, nuclear medicine. Each chapter is devoted to a particular organ system or topic relevant to the risks and benefits involved in nuclear medicine studies. The emphasis is on presenting the rationales for ordering the various clinical imaging procedures performed in most nuclear medicine departments. Where appropriate, alternative imaging modalities including ultrasound, computed tomography imaging, and radiographic special procedures are discussed. Comparative data between nuclear medicine imaging and other modalities are presented to help guide the practicing clinician in the selection of the most appropriate procedure for a given problem.

    Sudan is endowed with a variety of indigenous goat breeds which are used for meat and milk production and which are well adapted to the local environment. The aim of the present study was to determine the genetic diversity and relationship within and between the four main Sudanese breeds of Nubian, Desert, Taggar and Nilotic goats. Using the 50 K SNP chip, 24 animals of each breed were genotyped. More than 96% of high quality SNPs were polymorphic with an average minor allele frequency of 0.3. In all breeds, no significant difference between observed (0.4) and expected (0.4) heterozygosity was found and the inbreeding coefficients (F IS ) did not differ from zero. F st coefficients for the genetic distance between breeds also did not significantly deviate from zero. In addition, the analysis of molecular variance revealed that 93% of the total variance in the examined population can be explained by differences among individuals, while only 7% result from differences between the breeds. These findings provide evidence for high genetic diversity and little inbreeding within breeds on one hand, and low diversity between breeds on the other hand. Further examinations using Nei's genetic distance and STRUCTURE analysis clustered Taggar goats distinct from the other breeds. In a principal component (PC) analysis, PC1 could separate Taggar, Nilotic and a mix of Nubian and Desert goats into three groups. The SNPs that contributed strongly to PC1 showed high F st values in Taggar goat versus the other goat breeds. PCA allowed us to identify target genomic regions which contain genes known to influence growth, development, bone formation and the immune system. The information on the genetic variability and diversity in this study confirmed that Taggar goat is genetically different from the other goat breeds in Sudan. The SNPs identified by the first principal components show high F st values in Taggar goat and allowed to identify candidate genes which can be used in the

    Health and tourism is an emerging theme in research. Focus of this article is on travel medicine, which is a well-established discipline in the medical sciences, but not yet quite so in the social sciences. There is a limited insight into the relationship between innovations and developments...... in medicines on the one hand, and economics and institutionalisation of tourism on the other hand. The article explores this issue. Three narratives provide examples of the interconnections. The first case describes developments in drugs for malaria and relations with tourism. The second case addresses...... recreational drugs. The third case investigates the concept of wilderness medicine and the pharmaceuticals and medical gears that facilitate this category of tourism. Thus, the paper demonstrates through some examples that innovations in the medical fields and institutionalisation of the use of medicine may...

    Lots of plants belonging to Asteraceae family are very popular in folk medicine in Poland. These plants are also known as being rich in acidic polysaccharides, due to the presence of hexuronic acids or its derivatives. Our preliminary experiments have shown that the extract from Conyza canadensis L. possesses various biological activity, including antiplatelet, antiocoagulant and antioxidant properties. The aim of our study was to assess if macromolecular glycoconjugates from selected herbal plants of Asteraceae family: Achillea millefolium L., Arnica montana L., Echinacea purpurea L., Solidago virgaurea L., Chamomilla recutita (L.) Rauschert., and Conyza canadensis L. protect platelet proteins against nitrative and oxidative damage induced by peroxynitrite, which is responsible for oxidative/nitrative modifications of platelet proteins: the formation of 3-nitrotyrosine and carbonyl groups. These modifications may lead to changes of blood platelet functions and can have pathological consequences. The role of these different medicinal plants in the defence against oxidative/nitrative stress in human platelets is still unknown, therefore the oxidative damage to platelet proteins induced by peroxynitrite and protectory effects of tested conjugates by the estimation of carbonyl group level and nitrotyrosine formation (a marker of protein nitration) were studied in vitro. The antioxidative properties of the polyphenolic-polysaccharide conjugates from selected tested medicinal plants were also compared with the action of a well characterized antioxidative commercial polyphenol - resveratrol (3,4',5-trihydroxystilbene). The obtained results demonstrate that the compounds from herbal plants: A. millefolium, A. montana, E. purpurea, C. recutita, S. virgaurea, possess antioxidative properties and protect platelet proteins against peroxynitrite toxicity in vitro, similar to the glycoconjugates from C. canadensis. However, in the comparative studies, the polyphenolic

  5. From cumulative cultural transmission to evidence-based medicine: Evolution of medicinal plant knowledge in Southern Italy

    Full Text Available In Mediterranean cultures written records of medicinal plant use have a long tradition. This written record contributed to building a consensus about what was perceived to be an efficacious pharmacopoeia. Passed down through millennia, these scripts have transmitted knowledge about plant uses, with high fidelity, to scholars and laypersons alike. Herbal medicine’s importance and the long-standing written record call for a better understanding of the mechanisms influencing the transmission of contemporary medicinal plant knowledge. Here we contextualize herbal medicine within evolutionary medicine and cultural evolution. Cumulative knowledge transmission is approached by estimating the causal effect of two seminal scripts about materia medica written by Dioscorides and Galen, two classical Greco-Roman physicians, on today’s medicinal plant use in the Southern Italian regions of Campania, Sardinia and Sicily. Plant-use combinations are treated as transmissible cultural traits (or memes, which in analogy to the biological evolution of genetic traits, are subjected to mutation and selection. Our results suggest that until today ancient scripts have exerted a strong influence on the use of herbal medicine. We conclude that the repeated empirical testing and scientific study of health care claims is guiding and shaping the selection of efficacious treatments and evidence-based herbal medicine.

  6. Defining the Nation: National Identity in South Sudanese Media Discourse Eine Nation definieren: Die nationale Identität im südsudanesischen Mediendiskurs

    2012-01-01

    Full Text Available This article examines debates about national identity in the media landscape of post-referendum and post-independence South Sudan. Having never existed as a sovereign state and with its citizens being a minority group in Sudan, collective action among South Sudanese has historically been shaped in response to external pressures: in particular, the aggressive nation-building pursued by successive Khartoum governments that sought to Arabize and Islamize the South. Today, in the absence of a clear-cut enemy, it is a major challenge for South Sudan to devise a common identity that unites the putative nation beyond competing loyalties to ethnicity, tribe and family. Analysing opinion pieces from South Sudanese online media and placing them in the context of contemporary African nationalism, this article gives an initial overview of the issues that dominate the public debate on national identity: fear of tribalism and regionalism, commemoration of the liberation struggle, language politics, and the role of Christianity.Dieser Artikel widmet sich den Debatten, die in südsudanesischen Medien von der Nachreferendumszeit bis einige Monate nach der Unabhängigkeit über die nationale Identität geführt wurden. Der Südsudan hatte nie als souveräner Staat existiert und innerhalb des Sudan hatten die Südsudanesen eine Minderheit gebildet. In der Geschichte war gemeinschaftliches Handeln der Südsudanesen in erster Linie als Reaktion auf Druck von außen in Erscheinung getreten, insbesondere im Zusammenhang mit Arabisierungs- und Islamisierungsbestrebungen von Regierungen in Khartum. Heute fehlt ein eindeutiges Feindbild. Daher ist der Entwurf einer gemeinsamen Identität, die das Land über konkurrierende Loyalitäten zu Stamm, Ethnie oder Familie hinweg zu einen vermag, eine große Herausforderung für den Südsudan. Auf der Grundlage von Meinungsäußerungen in südsudanesischen Online-Zeitungen, die er zum „neuen“ afrikanischen

    Full Text Available This paper explores the ways in which national culture intersects with urban environs to produce multinational subjectivity. Specifically, this paper shows the activity of Eritrean and Sudanese asylum seekers in Tel Aviv, Israel, as particularly generative of the life world building of Southern Tel Aviv (known as Little Africa. Juxtaposing these spaces of urban life, this paper also looks at the Holot Detention Facility as a space of life as well, situating the asylum seeker along various, migratory paths towards citizenship. With the near-total recreation of African life, this paper examines the Neve Sha’anan neighborhood as supportive of the LGBT and migrant communities, evidencing the flourishing of national culture outside of traditional boundaries. Particularly, this paper looks at “The Prevention of Infiltration Law” to discuss ideas of “infiltrators” using frameworks from Foucault, Merleau-Ponty, Levinas, Jean-Luc Nancy and Achille Mbembe. Examining ideas of space, place, ethics, embodiment, law, the body, street art, border fences, architecture, and minimalism, this paper juxtaposes BLM (Black Lives Matter and BDS (Boycott, Divestment, Sanctions from a transnational perspective of world-building, asking the question of where can one call a place, home.    Keywords: Tel Aviv, Eritrea, Sudan, asylum seekers, infiltration

    Lower availability of medicines in Nigerian public health facilities-the most affordable option for the masses-undermines global health reforms to improve access to health for all, especially the chronically ill and poor. Thus, a sizeable proportion of healthcare users, irrespective of purchasing power, buy medicines at higher costs from for-profit pharmacies. We examined user evaluation of medicine availability in public facilities and how this influences their choice of where to buy medicines in selected states-Cross River, Enugu and Oyo-in Nigeria. We approached and interviewed 1711 healthcare users using a semi-structured, interviewer-administered questionnaire as they exited for-profit pharmacies after purchasing medicines. This ensured that both clients who had presented at health facilities (private/public) and those who did not were included. Information was collected on why respondents could not buy medicines at the hospitals they attended, their views of medicine availability and whether their choice of where to buy medicines is influenced by non-availability. Respondents' mean age was 37.7±14.4 years; 52% were males, 59% were married, 82% earned ≥NGN18, 000 (US$57.19) per month, and 72% were not insured. Majority (66%) had prescriptions; of this, 70% were from public facilities. Eighteen percent of all respondents indicated that all their medicines were usually available at the public facilities, most (29%), some (44%) and not always available (10%). Reasons for using for-profit pharmacies included: health workers attitudes (43%), referral by providers (43%); inadequate money to purchase all prescribed drugs (42%) and cumbersome processes for obtaining medicines. Lower availability of medicines has serious implications for healthcare behavior, especially because of poverty. It is crucial for government to fulfill its mandate of equitable access to care for all by making medicines available and cheap through reviving and sustaining the drug revolving

    Full Text Available Abstract Background In Africa low birth weight (LBW ( Methods In 1000 Sudanese mothers with singleton births, anthropometric measurements (weight, height, mid-arm circumference and newborn birth weight were taken within 24 hours of delivery. Furthermore, maternal education and socio-economic status were recorded. The effect of these maternal variables on gestational age and birth weight was investigated by receiver operating characteristic (ROC curves and by multivariate logistic regression analysis. Results Although maternal height was significantly correlated (p = 0.002 with gestational age, we did not find maternal characteristics of value in determining the risk for preterm birth. Birth order was the strongest determinant of birth weight compared to other maternal characteristics. The LBW rate of first born babies of 12.2% was nearly twice that of infants of multiparous mothers. Maternal age and all maternal anthropometric measurements were positively correlated (p 12 years of education. Conclusion Birth order and maternal height were found to be the most important maternal parameters which influences birth weight and the risk for LBW. The duration of maternal education and not social class was found to significantly affect the risk for LBW.

    Full Text Available Personalized medicine is a branch of medicine that proposes customization of healthcare in which decisions and treatment are tailored according to individual patient needs. The field of personalized medicine relies on genetic information, proteomic information and clinical patient characteristics to individualize treatment. With advances in genetics, proteomics, pharmacogenetics and knowledgeable patient population, the opportunity exists to deliver never before levels of personalized care. Although general dentists may consider personalized medicine a concept for the future, the reality is that its direct application to everyday dentistry is closer than one might think. Use of personalized medicine in dentistry, especially in periodontology is progressing rapidly, and dentist should consider this approach while treating patients. Google and PubMed search was done to select articles for present review. Total 17 articles were used to compile information.

    The aim of this study was to explore the barriers to accessing medicines and pharmacy services among refugees in Queensland, Australia, from the perspectives of resettled African refugees. A generic qualitative approach was used in this study. Resettled African refugees were recruited via a purposive snowball sampling method. The researcher collected data from different African refugee communities, specifically those from Sudanese, Congolese and Somalian communities. Participants were invited by a community health leader to participate in the study; a community health leader is a trained member of the refugee community who acts as a 'health information conduit' between refugees and the health system. Invitations were done either face-to-face, telephonically or by email. The focus groups were digitally recorded in English and transcribed verbatim by the researcher. Transcripts were entered into NVIVO© 11 and the data were analysed using inductive thematic analysis. Four focus groups were conducted between October and November 2014 in the city of Brisbane with African refugees, one with five Somali refugees, one with five Congolese refugees, one with three refugee community health leaders from South Sudan, Liberia and Eritrea and one with three refugee community health leaders from Uganda, Burundi and South Sudan. Eleven sub-themes emerged through the coding process, which resulted in four overarching themes: health system differences, navigating the Australian health system, communication barriers and health care-seeking behaviour. With regard to accessing medicines and pharmacy services, this study has shown that there is a gap between resettled refugees' expectations of health services and the reality of the Australian health system. Access barriers identified included language barriers, issues with the Translating and Interpreter Service, a lack of professional communication and cultural beliefs affecting health care-seeking behaviour. This exploratory study has

    The development of resistant to current antimalarial drugs is a major challenge in achieving malaria elimination status in many countries. Therefore there is a need for new antimalarial drugs. Medicinal plants have always been the major source for the search of new antimalarial drugs. The aim of this study was to screen selected Malaysian medicinal plants for their antiplasmodial properties. Each part of the plants were processed, defatted by hexane and sequentially extracted with dichloromethane, methanol and water. The antiplasmodial activities of 54 plant extracts from 14 species were determined by Plasmodium falciparum Histidine Rich Protein II ELISA technique. In order to determine the selectivity index (SI), all plant extracts demonstrating a good antiplasmodial activity were tested for their cytotoxicity activity against normal Madin-Darby Bovine Kidney (MDBK) cell lines by 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Twenty three extracts derived from Curcuma zedoaria (rhizome), Curcuma aeruginosa (rhizome), Alpinia galanga (rhizome), Morinda elliptica (leaf), Curcuma mangga (rhizome), Elephantopus scaber (leaf), Vitex negundo (leaf), Brucea javanica (leaf, root and seed), Annona muricata (leaf), Cinnamomun iners (leaf) and Vernonia amygdalina (leaf) showed promising antiplasmodial activities against the blood stage chloroquine resistant P. falciparum (EC50 toxicity effect to MDBK cells in vitro (SI ≥10). The extracts belonging to eleven plant species were able to perturb the growth of chloroquine resistant P. falciparum effectively. The findings justified the bioassay guided fractionation on these plants for the search of potent antimalarial compounds or formulation of standardized extracts which may enhance the antimalarial effect in vitro and in vivo.

    Availability of correct and adequate information about medicines is an important aspect in ensuring rational use of medicines and hence facilitating safety and expected efficacy of medicines during therapy. Package inserts have proven to be a good source of information to the prescribers and patients whereby they have been useful in highlighting important information pertaining proper use and handling of the medicines. The present study was aimed at establishing the extent to which package inserts of medicines circulating on the markets of the East African Community (EAC) Partner States conform to medicines information requirements as established in the harmonized guidelines as well as national guidelines. A total of 99 package inserts from six (6) types of medicines namely Albendazole, Artemether/Lumefantrine (ALu), Ciprofloxacin, Paracetamol, Amoxicillin and Metronidazole were purposefully collected from three EAC Partner States: Kenya, Tanzania and Uganda. The medicines were selected based on their indications as first line treatments, high rates of utilization within the medicines supply system and their positions in treatment of diseases of public importance across EAC Partner States. The inserts were evaluated on the availability of information regarding fifteen (15) parameters as extracted from the EAC harmonized guidelines for registration of medicines. Moreover, comparisons were made between the percentage conformity of the branded versus generic products, markets from which the samples were collected, origin of the manufacturer and type of medicine. Majority (93.9-100%) of the medicines' package inserts highly conformed to the inclusion of the information regarding the description and composition of the medications, indications, dosage and methods of administration, warnings and precautions, contraindications and storage conditions. However, the information on handling and disposal, container package description, excipients used, clinical pharmacology of

    Full Text Available Background: Cardiac dysfunctions have been recognized as a common complication of sickle cell anaemia (SCA, and together with pulmonary disorder accounts for many deaths in these patients. However, sickle cell traits appear clinically normal, although they have genetic abnormality. The aim of this study was to assess the effect of sickle cell trait on cardiac prognostic markers by measuring high density lipoprotein (HDL-C, low density lipoprotein (LDL-C, cardiac creatine kinase (CK-MB, ultra-sensitive C reactive protein (us-CRP, total homocysteine (Hyc, and N-terminal pro-brain natriuretic peptide (NT-pro BNP tests in adult Sudanese patients with sickle cell trait.Methods: A cross-sectional study was performed in 200 healthy volunteers as a control group and 200 diagnosed patients with sickle cell trait. It was carried out in Khartoum Specialized Hospital, Al-Bayan Hospital, Obayed Clinical Center and Dr. Nadir Specialized Hospital, Sudan between January 2015 and January 2016. All participants were between 20-32 years old. LDL-C, HDL-C, CK-MB, NT-proBNP and hs-CRP concentrations were measured by Hitachi 912 full-automated Chemistry Analyzer (Roche Diagnostics, Germany as manufacturer procedure, while homocysteine level was measured by ELISA technique using special kit.Results: When compared to control group, the levels of LDL-C, hs-CRP and NT-proBNP revealed significant increase in patients’ sera (p<0.001, while Hyc and CK-MB levels were increased insignificantly in patients with SCT (p=0.069, p=0.054 respectively. On the other hand, comparison to control group, HDL-C showed insignificant reduction in patients (p=0.099.Conclusion: The results suggest that sickle cell trait increased the risk of patient-related complication secondary to cardiac dysfunction.

    Full Text Available Plants have been used since ancient times as an important source of biologically active substances. The aim of the present study was to investigate the phytochemical constituents (flavonoids and phenolics, antioxidant potential, cytotoxicity against HepG2 (human hepato carcinoma cancer cell lines and the antimicrobial activity of the methanol extract of selected traditional medicinal plants collected from Mizoram, India. A number of phenolic compounds were detected using HPLC-DAD-ESI-TOF-MS, mainly Luteolin, Kaempferol, Myricetin, Gallic Acid, Quercetin and Rutin, some of which have been described for the first time in the selected plants. The total phenolic and flavonoid contents showed high variation ranging from 4.44 to 181.91 µg of Gallic Acid equivalent per milligram DW (GAE/mg DW and 3.17 to 102.2 µg of Quercetin/mg, respectively. The antioxidant capacity was determined by DPPH (IC50 values ranges from 34.22 to 131.4 µg/mL, ABTS (IC50 values ranges from 24.08 to 513.4 µg/mL and reducing power assays. Antimicrobial activity was assayed against gram positive (Staphylococcus aureus, gram negative (Escherichia coli, Pseudomonas aeruginosa and yeast (Candida albicans demonstrating that the methanol extracts of some plants were efficacious antimicrobial agents. Additionally, cytotoxicity was assessed on human hepato carcinoma (HepG2 cancer cell lines and found that the extracts of Albizia lebbeck, Dillenia indica and Bombax ceiba significantly decreased the cell viability at low concentrations with IC50 values of 24.03, 25.09 and 29.66 µg/mL, respectively. This is the first report of detection of phenolic compounds along with antimicrobial, antioxidant and cytotoxic potential of selected medicinal plants from India, which indicates that these plants might be valuable source for human and animal health.

    Full Text Available The presence of an isolated limb or limb parts from different individuals presents a major challenge for medicolegal investigators in establishing identification in cases of wars, mass disasters, and criminal assaults because different populations have different sizes and proportions. The measurement of lower limb dimensions showed a high success rate in establishing individual identity in terms of sex and stature in various populations. However, there is a paucity of data concerning the correlation within the lower limb parts. This study aims to assess the existence of relationships within lower limb parts and to develop regression formulae to reconstruct limb parts from one another. The tibial length, bimalleolar breadth, foot length, and foot breadth of 376 right-handed Sudanese adults were measured. The results showed that all variables were significantly larger in males than in females. A significant positive correlation (P<0.001 was found within the lower limb parts. Sex-specific linear equations and multiple regression equations were developed to reconstruct the lower limb parts in the presence of single dimension or multiple dimensions from the same limb. The use of multiple regression equations provided a better reconstruction than simple regression equations. These results are significant in forensics and orthopedic reconstructive surgery.

    Full Text Available Background: Type 1 diabetes is a challenging metabolic disorder for health authorities in Sudan. The objective of this study was to assess the level of glycemic control and to determine the prevalence of dyslipidemia and complications among individuals with type 1 diabetes in Sudan. Materials and Methods: Individuals with type 1 diabetes, who were having the disease for at least 1 year, were invited to participate in this study. Data were collected from two diabetes centers, in the Capital Khartoum and Atbara City, North of Sudan. Participants were interviewed using standardized pretested questionnaire to record medical history, sociodemographic data, and life style characteristics. Blood pressure, body mass index, and waist circumference were measured. Blood samples were taken for measurement of lipid profile and glycosylated hemoglobin. Results: A total of eighty individuals with type 1 diabetes volunteered to participate in this study, 37.5% of males and 62.5% of females. Majority of the patients were aged between 40 and 70 years old. There was poor glycemic control (glycosylated hemoglobin> 7%, in 83.8%. Age and sex were significant factors associated with poor glycemic control in this cohort. High cholesterol, triglyceride, and low density lipoprotein were seen in 76.2%, 27.5%, and 48.8% of participants, respectively. Low high density lipoprotein was seen in 33.8%. Hypertension was determined in 21.3%. Peripheral neuropathy, visual impairment, diabetic foot, and myocardial infarction were seen in 50%, 48.8%, 18.8%, and 2.5% of patients, respectively. Conclusion: Sudanese adults with type 1 diabetes have poor glycemic control, high prevalence of dyslipidemia, and long-term complications.

    The objectives of this study were to determine the levels of the mineral nutrients, especially of trace elements, in some food items commonly consumed in Sudan and to compare the results of this work with local and international data. Food samples of fruits and vegetables were collected from different localities in Sudan. The samples were then prepared and their Br, Ca, Co, Cu, Fe, Mg, Mn, P, Pb, Na, Rb, Sr, and Zn content were determined using Atomic absorption spectroscopy (AAS), X-ray fluorescence spectroscopy (XRF), flame photometry and colorimetry. Verified standards TDD-1D and Hay-9 (supplied by the IAEA) were measured using the techniques mentioned above for accuracy. The Sudanese food items analyzed were found to contain considerable ranges of nutrients as follows: - Concentration levels for some of these elements Ca, Cu and Fe show higher values in fruits (4709, 21, and 633 ppm, respectively), and lower in vegetables (4094, 13, and 255 ppm , respectively). Pb and Mn were higher in vegetables (2 and 32 ppm, respectively) and lower in fruits (1 and 18 ppm) respectively). Na and Zn were higher in vegetables (3149 and 26 ppm, respectively) and lower in fruits (269 and 13 ppm, respectively). The values obtained agree, in general, with data available from other countries. Variations were observed among certain varieties of food. (Authors)

    This study was carried out to determine the level of natural radioactivity and heavy metals content of Sudanese rock phosphate used as low cost fertilizer. Thirty samples collected from two types of local phosphate rocks from the Nuba mountains (Uro and Kurun) were used in this study and the activity concentrations of natural radioactivity determined using gamma spectroscopy were compared to those found in samples of imported phosphorous fertilizers Single Super phosphate (SSP) and Triple Super phosphate (TSP). The results showed that the ' Ra activity concentration was 0.6 - 0.8 Bq/g for Uro and 0.3 - 0.5 Bq/g for Kurun. As for the most commonly used imported fertilizer TSP, the result was found to be greater than that of Uro (around 1.0 Bq/g). The heavy metals content of Uro and Kurun rocks measured using X-ray Fluorescence Technique showed their levels were below the toxic levels reported by Christina (1991). It is evident that the environmental hazard is comparable in the local and imported fertilizers and is acceptable in both cases by international standards. The determine factor therefore in optioning for the use of a local or an imported brand should then be the fertilizing efficiency of the brand used against other economic consideration rather than the fertilizers environmental impact

    Full Text Available Abstract Background Worldwide particularly in developing countries, a large proportion of the population is at risk for tropical parasitic diseases. Several medicinal plants are still used traditionally against protozoal infections in Yemen and Saudi Arabia. Thus the present study investigated the in vitro antiprotozoal activity of twenty-five plants collected from the Arabian Peninsula. Methods Plant materials were extracted with methanol and screened in vitro against erythrocytic schizonts of Plasmodium falciparum, intracellular amastigotes of Leishmania infantum and Trypanosoma cruzi and free trypomastigotes of T. brucei. Cytotoxic activity was determined against MRC-5 cells to assess selectivity. The criterion for activity was an IC50 T. brucei and selectivity index of >4. Results Antiplasmodial activity was found in the extracts of Chrozophora oblongifolia, Ficus ingens, Lavandula dentata and Plectranthus barbatus. Amastigotes of T. cruzi were affected by Grewia erythraea, L. dentata, Tagetes minuta and Vernonia leopoldii. Activity against T. brucei was obtained in G. erythraea, L. dentata, P. barbatus and T. minuta. No relevant activity was found against L. infantum. High levels of cytotoxicity (MRC-5 IC50 Cupressus sempervirens, Kanahia laniflora and Kniphofia sumarae. Conclusion The results endorse that medicinal plants can be promising sources of natural products with antiprotozoal activity potential. The results support to some extent the traditional uses of some plants for the treatment of parasitic protozoal diseases.

    Multi-drug resistant strains of fungi and bacteria are imposing the need for new drugs. Reliable natural sources with minor side effects are needed to control anti-human pathogenic invaders specially bacteria. Given the demands for natural products that are inherently safe and environmentally compatible, the advancement in antimicrobial potential has provided a better alternative to synthetic resistance antibiotics. In the present investigation such types of medicinal plants were selected for analyses that are used by local herbal practioners for multiple diseases. Thirty three extracts of Achillea millefolium, Acorus calamus, Arnebia nobilis, Fumaria indica, Gymnema sylvestre, Origanum vulgare, Paeonia emodi, Peganum harmala, Psoralea corylifolia, Rauwolfia serpentina and Vetiveria zizanioides in chloroform, ethanol and hexane were investigated for their antimicrobial potential. These extracts were tested against eight microorganisms including four gram negative bacterial strains viz., Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Salmonella typhi, three gram positive bacterial strains Staphylococcus aureus, Bacillus subtilis and Bacillus cereus and a fungal strain viz., Candida albicans. Majority of the extracts showed marked antimicrobial potential against the tested microorganisms. (author)

    Full Text Available Abstract Selection of chemical markers is crucial for the quality control of herbal medicines, including authentication of genuine species, harvesting the best quality raw materials, evaluation of post-harvesting handling, assessment of intermediates and finished products, and detection of harmful or toxic ingredients. Ideal chemical markers should be the therapeutic components of herbal medicines. However, for most herbal medicines, the therapeutic components have not been fully elucidated or easily monitored. Bioactive, characteristic, main, synergistic, correlative, toxic and general components may be selected. This article reviews the effective use of chemical markers in the quality control of herbal medicines including the selection criteria considering the roles and physicochemical factors which may affect the effective use of chemical markers.

    Abstract A constitutional guarantee of access to essential medicines has been identified as an important indicator of government commitment to the progressive realization of the right to the highest attainable standard of health. The objective of this study was to evaluate provisions on access to essential medicines in national constitutions, to identify comprehensive examples of constitutional text on medicines that can be used as a model for other countries, and to evaluate the evolution of constitutional medicines-related rights since 2008. Relevant articles were selected from an inventory of constitutional texts from WHO member states. References to states’ legal obligations under international human rights law were evaluated. Twenty-two constitutions worldwide now oblige governments to protect and/or to fulfill accessibility of, availability of, and/or quality of medicines. Since 2008, state responsibilities to fulfill access to essential medicines have expanded in five constitutions, been maintained in four constitutions, and have regressed in one constitution. Government commitments to essential medicines are an important foundation of health system equity and are included increasingly in state constitutions. PMID:27781006

    Complementary and alternative medicine have undoubtedly been gaining ground on the healthcare market, thus the vital question arises why patients choose these treatments, oftentimes at the cost of discontinuing the Western medical therapy. The aim of the authors was to investigate and scrutinize factors leading to the utilization of various alternative medical services. The basis of this qualitative research was medical anthropological fieldwork conducted at a clinic of Traditional Chinese Medicine including participant observation (355 hours), unstructured interviews with patients (n = 93) and in-depth interviews (n = 14). Patients of alternative medical systems often do not receive a diagnosis, explanation or cure for their illness from Western medicine, or they do not agree with what they are offered. In other instances, patients choose alternative medicine because it exhibits a philosophical congruence with their already existing explanatory model, that is, previous concepts of world, man or illness. A particular therapy is always part of a cultural system and it is embedded in a specific psycho-social context, hence choice of therapy must be interpreted in accordance with this perspective.

    Management of type 2 diabetes by delaying or preventing glucose absorption using natural products is gaining significant attention. Edible mushrooms are well documented for their nutritional and medicinal properties. This investigation was designed to evaluate the antidiabetic activity of aqueous extracts of selected culinary-medicinal mushrooms, namely, Pleurotus ostreatus, Calocybe indica, and Volvariella volvacea, using in vitro models (α-amylase inhibition assay, glucose uptake by yeast cells, and glucose adsorption capacity). The most active extract was subsequently examined in vivo using the oral starch tolerance test in mice. All prepared extracts showed dose-dependent inhibition of α-amylase and an increase in glucose transport across yeast cells. C. indica extract was the most active α-amylase inhibitor (half-maximal inhibitory concentration, 18.07 ± 0.75 mg/mL) and exhibited maximum glucose uptake by yeast cells (77.53 ± 0.97% at 35 mg/mL). All extracts demonstrated weak glucose adsorption ability. The positive in vitro tests for C. indica paved the way for in vivo studies. C. indica extract (200 and 400 mg/kg) significantly (P < 0.05) reduced postprandial blood glucose peaks in mice challenged with starch. The extract (400 mg/kg) and acarbose normalized blood glucose levels at 180 minutes, when they were statistically similar to values in normal mice. Thus, it may be concluded that the antidiabetic effect of C. indica is mediated by inhibition of starch metabolism (α-amylase inhibition), increased glucose uptake by peripheral cells (promotion of glucose uptake by yeast cells), and mild entrapment (adsorption) of glucose. Hence, C. indica can be developed as antidiabetic drug after detailed pharmacological studies.

    Selection of medicines that is inappropriate will lead to an empty result at medicines, this has an impact on medical services and economic value in hospital. The importance of an appropriate medicine selection process requires an automated way to select need based on the development of the patient's illness. In this study, we analyzed patient prescriptions to identify the relationship between the disease and the medicine used by the physician in treating the patient's illness. The analytical framework includes: (1) patient prescription data collection, (2) applying k-means clustering to classify the top 10 diseases, (3) applying Apriori algorithm to find association rules based on support, confidence and lift value. The results of the tests of patient prescription datasets in 2015-2016, the application of the k-means algorithm for the clustering of 10 dominant diseases significantly affects the value of trust and support of all association rules on the Apriori algorithm making it more consistent with finding association rules of disease and related medicine. The value of support, confidence and the lift value of disease and related medicine can be used as recommendations for appropriate medicine selection. Based on the conditions of disease progressions of the hospital, there is so more optimal medicine procurement.

    Nuclear medicine remains a vibrant and dynamic medical specialty because it so adeptly marries advances in basic science research, technology, and medical practice in attempting to solve patients' problems. As a physicist, it is my responsibility to identify or design new instrumentation and techniques, and to implement, validate, and help apply these new approaches in the practice of nuclear medicine. At Johns Hopkins, we are currently in the process of purchasing both a single-photon/coincidence tomographic imaging system and a dedicated positron emission tomography (PET) scanner. Given the exciting advances that have been made, but the conflicting opinions of manufacturers and colleagues alike regarding ''best'' choices, it seemed useful to review what is new now, and what is on the horizon, to help identify all of the important considerations in the design and selection of an imaging system. It is important to note that many of the ''advances'' described here are in an early stage of development, and may never make it to routine clinical practice. Further, not all of the advances are of equal importance, or have the same degree of general clinical applicability. Please also note that the references contained herein are for illustrative purposes and are not all-inclusive; no implication that those chosen are ''better'' than others not mentioned is intended.

    Internal medicine residents today face significant challenges in caring for an increasingly complex patient population within ever-changing education and health care environments. As a result, medical educators, health care system leaders, payers, and patients are demanding change and accountability in graduate medical education (GME). A 2012 Society of General Internal Medicine (SGIM) retreat identified medical education as an area for collaboration between internal medicine and geriatric medicine. The authors first determined a short-term research agenda for resident education by mapping selected internal medicine reporting milestones to geriatrics competencies, and listing available sample learner assessment tools. Next, the authors proposed a strategy for long-term collaboration in three priority areas in clinical medicine that are challenging for residents today: (1) team-based care, (2) transitions and readmissions, and (3) multi-morbidity. The short-term agenda focuses on learner assessment, while the long-term agenda allows for program evaluation and improvement. This model of collaboration in medical education combines the resources and expertise of internal medicine and geriatric medicine educators with the goal of increasing innovation and improving outcomes in GME targeting the needs of our residents and their patients.

    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.

    Post-migration stressors represent significant obstacle to refugee adjustment, and continued exposure to post-migration stressors can negatively affect mental and physical health. Communities of support maintained over the Internet may provide a sense of constancy and reliability that may insulate against the negative effects of stress. We conducted five focus group interviews with Iraqi and Sudanese refugees to understand how refugees use the Internet to access support in their daily lives. Four trends were observed: (a) Internet use was related to culture of origin, (b) refugees were reluctant to explore online, (c) children served as brokers of online knowledge, and (d) limited Internet access is associated with increased time and financial obligations. This study aims to contribute to theory on Internet-mediated social support and to refugee health by creating smoother pathways to self-sufficiency and allowing refugees to exhibit agency in constructing and maintaining online networks of support. © The Author(s) 2015.

    Selection in reproductive medicine today relies on normative assessments of what ‘good life’ consists of. This paper explores the terms under which such assessments are made by focusing on three particular concepts of ‘quality’: quality of life, biological quality and population quality....... It is suggested that the apparently conflicting hypes, hopes and fears that surround reproductive medicine can co-circulate because of the different forms of normative assessment that these concepts allow. To ensure clarity in bioethical deliberations about selection, it is necessary to highlight how...

    2006-09-01

    Near infrared (NIR) spectroscopy has raised a lot of interest in the pharmaceutical industry because it is a rapid and cost-effective analytical type of spectroscopy with no need for extensive sample preparation, and with the easy-realizable ability of on-line application. The NIR technology can increase the quality control standard of the Chinese medicine and accelerate the entry into the international market. In the present paper, two methods for wavelength selection are applied to the measurement of borneol, one of which is the multiple-chain stepwise, which tends to select many variables in the same area containing valuable information, and the other is the mixture genetic algorithm, which incorporates simulated annealing so as to improve the local searching ability while maintaining the global searching ability. The results present that the number of wavelength is reduced to 16% compared with the original number of wavelength, and the prediction accuracy has increased 47.6%. Therefore, the method of wavelength selection is a good way to enhance the prediction accuracy and simplify the model in NIR region.

    An examination was made concerning the relationships between Sudanese secondary science teachers' pupil control ideology and their students' perceptions/observations of the psychosocial environment of their science classrooms. One hundred secondary science teachers were classified as possessing humanistic (N = 20) or custodial (N = 20) control ideologies. A class (N = 40) of students was randomly selected for every teacher in both groups. The findings revealed that no significant relationships existed between the control ideologies of the teachers and their students' perceptions/observations of the classroom environment. Custodialism in control ideology was significantly related to the classroom environment psychosocial aspect of low support. Discussion and implications of the findings have been approached from both Sudanese and American perspectives.

    Decision-making for medicines to be accepted in Iran's public health insurance reimbursement list is a complex process and involves factors, which should be considered in applying a coverage for medicine costs. These processes and factors are not wholly assessed, while assessment of these factors is an essential need for getting a transparent and evidence-based approach toward medicine reimbursement in Iran. This paper aims to show an evidence-based approach toward medicine selection criteria to inform the medical reimbursement decision makers in Iranian health insurance organizations. To explore an adaptable decision-making framework while incorporating a method called "Borda" in medicine reimbursement assessment, we used the help of an expert group including decision makers and clinical researchers who are also policy makers to appraise the five chief criteria that have three sub criteria (Precision, Interpretability, and Cost). Also software "Math-lab"7, "SPSS" 17 and Excel 2007 were used in this study. "Borda" estimates the amount of perceived values from different criteria and creates a range from one to five while providing a comprehensive measurement of a large spectrum of criteria. Participants reported that the framework provided an efficient approach to systematic consideration in a pragmatic format consisting of many parts to guide decision-makings, including criteria and value (a model with the core of Borda) and evidences (medicine reimbursement based on criteria). The most important criterion for medicine acceptance in health insurance companies, in Iran, is the "life-threatening" factor and "evidence quality" is accounted as the fifth important factor. This pilot study showed the usefulness of incorporating Borda in medicine reimbursement decisions to support a transparent and systematic appraisal of health insurance companies' deeds. Further research is needed to advance Borda-based approaches that are effective on health insurance decision making.

    Halogenation is commonly used in medicinal chemistry to improve the potency of pharmaceutical leads. While synthetic methods for halogenation present selectivity and reactivity challenges, halogenases have evolved over time to perform selective reactions under benign conditions. The optimization of halogenation biocatalysts has utilized enzyme evolution and structure-based engineering alongside biotransformation in a variety of systems to generate stable site-selective variants. The recent improvements in halogenase-catalyzed reactions has demonstrated the utility of these biocatalysts for industrial purposes, and their ability to achieve a broad substrate scope implies a synthetic tractability with increasing relevance in medicinal chemistry.

    Space medicine is fundamental to the human exploration of space. It supports survival, function and performance in this challenging and potentially lethal environment. It is international, intercultural and interdisciplinary, operating at the boundaries of exploration, science, technology and medicine. Space medicine is also the latest UK specialty to be recognized by the Royal College of Physicians in the UK and the General Medical Council. This review introduces the field of space medicine and describes the different types of spaceflight, environmental challenges, associated medical and physiological effects, and operational medical considerations. It will describe the varied roles of the space medicine doctor, including the conduct of surgery and anaesthesia, and concludes with a vision of the future for space medicine in the UK.Space medicine doctors have a responsibility to space workers and spaceflight participants. These 'flight surgeons' are key in developing mitigation strategies to ensure the safety, health and performance of space travellers in what is an extreme and hazardous environment. This includes all phases from selection, training and spaceflight itself to post-flight rehabilitation and long-term health. The recent recognition of the speciality provides a pathway to train in this fascinating field of medicine and is a key enabler for the UK Government's commercial spaceflight ambition. © Crown copyright 2017.

    Plants have been used since ancient times as an important source of biologically active substances. The aim of the present study was to investigate the phytochemical constituents (flavonoids and phenolics), antioxidant potential, cytotoxicity against HepG2 (human hepato carcinoma) cancer cell lines, and the antimicrobial activity of the methanol extract of selected traditional medicinal plants collected from Mizoram, India. A number of phenolic compounds were detected using HPLC-DAD-ESI-TOF-MS, mainly Luteolin, Kaempferol, Myricetin, Gallic Acid, Quercetin and Rutin, some of which have been described for the first time in the selected plants. The total phenolic and flavonoid contents showed high variation ranging from 4.44 to 181.91 μg of Gallic Acid equivalent per milligram DW (GAE/mg DW) and 3.17 to 102.2 μg of Quercetin/mg, respectively. The antioxidant capacity was determined by DPPH (IC50 values ranges from 34.22 to 131.4 μg/mL), ABTS (IC50 values ranges from 24.08 to 513.4 μg/mL), and reducing power assays. Antimicrobial activity was assayed against gram positive (Staphylococcus aureus), gram negative (Escherichia coli, Pseudomonas aeruginosa), and yeast (Candida albicans) demonstrating that the methanol extracts of some plants were efficacious antimicrobial agents. Additionally, cytotoxicity was assessed on human hepato carcinoma (HepG2) cancer cell lines and found that the extracts of Albizia lebbeck, Dillenia indica, and Bombax ceiba significantly decreased the cell viability at low concentrations with IC50 values of 24.03, 25.09, and 29.66 μg/mL, respectively. This is the first report of detection of phenolic compounds along with antimicrobial, antioxidant and cytotoxic potential of selected medicinal plants from India, which indicates that these plants might be valuable source for human and animal health.

    Allergic rhinitis has long been a worldwide health problem with a global growth trend. The use of traditional Chinese medicines alone or integrated Chinese-Western medicines for its treatment is quite common in Taiwan. Respiratory diseases account for the majority of outpatient traditional Chinese medicine treatment, while allergic rhinitis accounts for the majority of respiratory diseases. We hereby conduct a comparative analysis between traditional Chinese medicine treatments and western medicine treatments for allergic rhinitis in Taiwan. The results of the analysis on the prescription difference of traditional Chinese medicine and western medicine treatments would be helpful to clinical guide and health policy decision making of ethnopharmacological therapy. Patients diagnosed as allergic rhinitis with diagnostic code 470-478 (ICD-9-CM) were selected as subjects from 2009-2010 National Health Insurance Research Database based on the claim data from the nationwide National Health Insurance in Taiwan. This retrospective study used Chi-Square test to test the effects of gender and age on visit of traditional Chinese medicine, western medicine, and integrated Chinese-Western medicine treatments. A total of 45,804 patients diagnosed as allergic rhinitis with ICD-9-CM 470-478 were identified from 2009-2010 NHIRD. There were 36,874 subjects for western medicine treatment alone, 5829 subjects for traditional Chinese medicine treatment alone, and 3101 subjects for integrated Chinese-Western medicine treatment. Female patients were more than male in three treatments. 0-9 years children had the highest visit frequency in western medicine and integrated Chinese-Western medicine groups, while 10-19 years young-age rank the highest in traditional Chinese medicine group. The Chi-square test of independence showed that the effects of gender and age on visit of three treatments were significant. The prescription drugs of western medicine treatment alone were almost for

    In Indonesia, herbal medicines are usually produced by small and medium enterprises which are relatively low in quality control. The purpose of this paper is to report that we have developed a taste sensor system with global selectivity, i.e., electronic tongue (e-tongue) for differentiation of Indonesian herbal medicines. The e-tongue was composed of five kinds of ion selective electrodes as working electrodes, data acquisition system, and pattern recognition system. Each ion selective electrode (ISE) was built by attaching lipid/polymer membrane. For this purpose, the five kinds of membranes were built by mixing lipid, plasticizer (nitrophenyl octyl ether/NPOE), polyvinyl chloride (PVC), and tetrahydrofuran (THF). In this study, we employed five kinds of lipid, namely oleic acid (OA), dioctyl phosphate (DOP), decyl alcohol (DA), dodecylamine (DDC), and trioctyl methyl ammonium chloride (TOMA). In this case, the membranes transform information of taste substances into electric signal. The five kinds of Indonesian herbal medicine were purchased from local supermarket in Yogyakarta, i.e., kunyit asam (made from turmeric and tamarind), beras kencur (made from rice and kencur), jahe wangi (made from ginger and fragrance), sirih wangi (made from betel leaf), and temulawak (made from Javanese ginger). Prior to detecting the taste from the Indonesian herbal medicine samples, each ion selective electrode was tested with five basic taste samples, i.e., for saltiness, sweetness, umami, bitterness, and sourness. All ISEs showed global selectivity to all samples. Furthermore, the array of ISEs showed specific response pattern to each Indonesian herbal medicine. For pattern recognition system, we employed principle component analysis (PCA). As a result, the e-tongue was able to differentiate five kinds of Indonesian herbal medicines, proven by the total variance of first and second principle components is about 93%. For the future, the e-tongue may be developed for quality

    Ten years ago specialists in Nuclear Medicine from the South of France formed an Association called ACOMEN. The objectives were to create a permanent exchange of ideas between members and a close collaboration with physicians. The group objectives have led to a combination of efforts on the behalf of each one to clarify our techniques for physicians having recourse to this speciality as well as the various categories of students passing through the Nuclear Medicine Departments. Different groups within the ACOMEN were assigned to specific subjects. Each group was in charge of building the framework of a certain topic, which was then illustrated by selected documents contributed by all members. A slide collection, complete with an explanatory booklet is the final result of this collaboration. Thus anyone concerned in any way, with nuclear medicine, is able to quickly become familiar with the techniques of the speciality, to be aware of its possibilities and its limitations and to update his hnowledge. One realizes that the first theme selected was not the easiest; pulmonary radionuclide explorations are, as everyone knows, variable and even personalized. However, the choice was deliberate. The difficulty should stimulate those responsible for the other themes as well as the people working with them. There is already a slide collection available to anyone who wishes to learn about the use of nuclear medicine in the diagnosis of respiratory diseases [fr

    In Western societies, Alzheimer's disease (AD) is the most common form of dementia and the sixth leading cause of death. In recent years, the concept of precision medicine, an approach for disease prevention and treatment that is personalized to an individual's specific pattern of genetic variability, environment and lifestyle factors, has emerged. While for some diseases, in particular select cancers and a few monogenetic disorders such as cystic fibrosis, significant advances in precision medicine have been made over the past years, for most other diseases precision medicine is only in its beginning. To advance the application of precision medicine to a wider spectrum of disorders, governments around the world are starting to launch Precision Medicine Initiatives, major efforts to generate the extensive scientific knowledge needed to integrate the model of precision medicine into every day clinical practice. In this article we summarize the state of precision medicine in AD, review major obstacles in its development, and discuss its benefits in this highly prevalent, clinically and pathologically complex disease.

    In Africa low birth weight (LBW) (birth weight. In 1000 Sudanese mothers with singleton births, anthropometric measurements (weight, height, mid-arm circumference) and newborn birth weight were taken within 24 hours of delivery. Furthermore, maternal education and socio-economic status were recorded. The effect of these maternal variables on gestational age and birth weight was investigated by receiver operating characteristic (ROC) curves and by multivariate logistic regression analysis. Although maternal height was significantly correlated (p = 0.002) with gestational age, we did not find maternal characteristics of value in determining the risk for preterm birth. Birth order was the strongest determinant of birth weight compared to other maternal characteristics. The LBW rate of first born babies of 12.2% was nearly twice that of infants of multiparous mothers. Maternal age and all maternal anthropometric measurements were positively correlated (p birth weight. A maternal height of birth weight, while the number of years of education was positively correlated with birth weight (p = 0.01). The LBW rate decreased from 9.2% for 12 years of education. Birth order and maternal height were found to be the most important maternal parameters which influences birth weight and the risk for LBW. The duration of maternal education and not social class was found to significantly affect the risk for LBW.

    Five culinary-medicinal mushrooms are commonly available in the Malaysian market: Agaricus bisporus (white and brown), Ganoderma lucidum, Hypsizygus marmoreus, Pleurotus floridanus, and P. pulmonarius. These species were selected for use in the current study, the aim of which was to investigate the antimelanogenesis and anti-inflammatory activity of these mushrooms in an attempt to evaluate their potential use in cosmeceuticals. Mushroom fruiting bodies were extracted with hot water, and the extracts were freeze-dried before testing. The antimelanogenesis activity of the extracts was determined by cell viability assay, measurement of intracellular melanin content, and cellular tyrosinase assay with B16F10 melanoma cells. The anti-inflammatory activity of the mushroom extracts was tested by measuring the levels of nitric oxide (NO), tumor necrosis factor (TNF)-α, and interleukin-10 excreted by RAW264.7 macrophages. Brown A. bisporus reduced intracellular melanin content to the largest extent-up to 57.05 ± 3.90%-without a cytotoxic effect on B16F10 melanoma cells. This extract also reduced cellular tyrosinase activity to 17.93 ± 2.65%, performing better than kojic acid, the positive control. In parallel, the extract from brown A. bisporus, at the highest concentration tested, has appreciable anti-inflammatory activity through reductions of NO and TNF-α levels. The other 5 extracts showed moderate antimelanogenesis and anti-inflammatory activities. In summary, our findings show that A. bisporus (brown) extract has the potential to be used as an ingredient in whitening skincare products and to sooth the inflammatory response on the skin.

    The aim of the present study was to evaluate the effect of gamma irradiation treatment on seeds of pepper cress (lepidium sativum L), seeds of black mustard (brassica nigra L.Koch), leaves of lemon grass (cymbopogon citratus), and calyces of roselle (hibiscus sabdariffa L), pods of senna (cassia senna L) and pods prickly acacia (Acacia nilotica L.). The radiation processing was carried out at dose levels of 0, 5, 10. 15 kGy. The irradiated and control samples were analyzed for microbial load, tannins and total phenol content as well as DPPH scavenging activity. The results indicated that gamma radiation treatment significantly reduced microbial load and showed that the total microbial load decreased linearly with absorbed radiation dose. They, also, indicated maximum reduction in tannin content in lemon grass, prickly acacia and roselle. On the other hand, irradiation with 15 kGy increased the tannin and phenol contents in black mustard, pepper cress and senna and reduced the phenol content of roselle and prickly acacia. The results also revealed that gamma irradiation resulted in significant decrease of DPPH radical scavenging activity of the different studied methanolic extracts with exception of pepper cress seeds.(Author)

    Leucorrhea or vaginal discharge is a conventional complaint. It is generally whitish, yellowish, or greenish vaginal discharge in females that might be normal or a symptom of infection. It is almost mucus discharge, which exhibit exfoliation of vaginal epithelial cells due to estrogen influence on the vaginal mucosa. It is important to identify the differences between physiologic and pathologic discharges. Leucorrhea is a well-known disease in Iranian traditional medicine (ITM). In their manuscripts, the word "Sayalan-e rahem" was used by Avicenna and some other Iranian traditional practitioners to describe this condition. Ancient practitioners believed that excessive residue (kesrate fozool) and weakness of digestion (Za'afe hazm) were the main causes of leucorrhea, for which herbal therapy was the main proposed treatment. In the present study, medicinal plants used in ITM for leucorrhea are introduced. In this research, six Iranian traditional textbooks including Canon of Medicine (Avicena 980-1037 AD), A-Hawi (Razes 865-925 AD), Tuhfat ul-Momineen (Mo'men tonekaboni, 17th century), Makhzan-ul-Adwiah (Aghili 18th century), Ikhtiarat Badi'i (Ansari 1329-1404 AD), and al-jāmi li-mufradāt al-adwiyawa al-aghdhiy (Ibn al-Baitar 1197 AD) were studied and searched for anti-leucorrhea medicines. Then the herbal medicines were selected and scored depending on their frequency in the above-mentioned textbooks. Additional attention was paid to provide the most suitable scientific name for each plant. This study introduced many Materia Medica with anti-leucorrhea activity and among them seven herbs including Rubus fruticosus L., Rhus coriaria L., Phoenix dactylifera L., Pimpinella anisum L., Rumex acetosa L., Olea europaea L. and Quercus lusitanica Lam. showed the most repetition in ITM prescriptions. These herbs can be introduced as new anti-leucorrhea herbal medicines for clinical research.

    Cancer cases numbers are increasing worldwide positioning this disease as the second cause of mortality for both sexes. Medicinal plants have been used in the fight against cancer as the basis for drug discovery and nowadays more than 70% of anticancer drugs have a natural origin. Mexico is regarded for its cultural and biological diversity, which is reflected in the vast traditional knowledge of herbal remedies. In this review we examined herbal remedies employed in colorectal cancer treatment (CRC). The goal of this work was to gather scientific reports of plants used in Mexican traditional medicine for CRC treatment. We performed a search on scientific literature databases using as keywords: "colon cancer", "gastric cancer", "cytotoxicity", studies "in vitro and in vivo", in combination with "Mexican medicinal plants" or "Mexican herbal remedies". The selection criteria of cytotoxic activity for extracts or pure compounds was based on the National Cancer Institute of USA recommendations of effective dose 50 (ED50) of ≤20μg/mL and ≤4μg/mL, respectively. In this review we report 25 botanic families and 39 species of plants used for the treatment of colon cancer in Mexico with evidence in studies in vitro and in vivo. Medicinal plants are still a great source of novel chemical structures with antineoplastic potential as it is proven in this work. The selection criteria and activity was narrowed for methodological purposes, nevertheless, drug discovery of natural origin continues to be a highly attractive R&D strategy.

    Precision medicine is interchangeably used with personalized medicine, genomic medicine and individualized medicine. Collectively, these terms refer to at least 5 distinct concepts in the context of AML. 1st, using molecular or omics data (e.g. genomics, epigenomics, transcriptomics, proteomics) to delineate or define subtypes of AML. 2nd, using these data to select the best therapy for someone with an AML subtype, such as a person with a FLT3-mutation. 3rd, using these data to monitor therapy-response such as measurable residual disease [MRD]-testing. 4th, using results of MRD-testing to select from amongst therapy-options such as additional chemotherapy or a haematopoietic cell transplant. And 5th, using these data to identify persons with hereditary forms of AML with potential therapy and surveillance implications. Here, we review these 5 conceptions and delineate where precision medicine is likely to afford greatest hope and where instead our rhetoric may constitute hype. Copyright © 2016 Elsevier Ltd.

    This study was performed to investigate the influence of cancer on selected trace elements among sudanese patients with confirmed breast cancer. Eighty samples of cancerous and normal tissues (total of one hundred and sixty) were obtained from the same breast of the same subject from different hospitals in Khartoum State. Samples were freeze dried and analyzed using neutron activation analysis (NAA). Neutron irradiations were performed at Egypt second research reactor with a maximum thermal flux of 2.37 Χ 10 14 n cm -2 s -1 . To examine if there was any difference in the concentrations of elements from normal and malignant tissues; Wilcox on signed ranks test was used. It was found that Al, Mn, Mg, Se, Zn, and Cr elements from the malignant tissues are significantly elevated (p 0.05). The results obtained have shown consistency with results obtained by some previous studies, however, no data could be found for the elements Mg, Cr, and Sc.(Author)

    The concentration of heavy trace elements chromium, manganese, nickel, copper, zinc, cadmium, and lead was measured in three main groups of alage, green, brown and red from the Sudanese coastal water of the Red Sea at seven main locations. The analyses were performed using atomic absorption spectrophotometry and x-ray fluorescence. Based on the overall average concentration (ppm), manganese was the most abundant element, (range 22.64-144.77) followed by chromium (rang 8.40-14.51), zinc (range 5.82-14.23), nickel (range 4.27-6.48) copper (range 2.83-7.75) lead range (1.29-1.80) and cadmium (rang 0.05-0.15). On comparing samples results at all locations, the results showed that Sawakin locations (1) and (2) algae have a highest content of trace elements. The concentration of trace elements in marine algae at, Sawakin (1), Klanieb and Sawakin (2) shows the higher uptake of lead giving the average of 1.69, 1.70, and 1.80, respectively compared with other locations, where the lowest concentration of manganese is observed at Sawakin (1) (38.19 ppm) and Sawakin (2) (41.04 ppm) with relative excess of lead concentration (1.69 and 1.80 ppm). Data obtained in this study were treated using classical descriptive statistics to explain the measuring central tendency. Correlation coefficient was also used to examine the relationship of different elements. Upon comparing the elemental concentration of the Red Sea alage with published literature, marine algae collected from the study area showed relative agreement with data reported but Sawakin harbor can be considered as slightly contaminated area by heavy metals. The study showed that the red algae has higher uptake of trace elements studied than brown and green algae with some variations of metal concentrations in some species which were apparently related to the specific accumulation capacity of each particular species. These species suggest their suitability for utilization as biomonitor for heavy metals in the Red Sea coastal

    The concept of molecular imaging has taken off over the past 15 years to the point of the renaming of the Society of Nuclear Medicine (Society of Nuclear Medicine and Molecular Imaging) and Journals (European Journal of Nuclear Medicine and Molecular Imaging) and offering of medical fellowships specific to this area of study. Molecular imaging has always been at the core of functional imaging related to nuclear medicine. Even before the phrase molecular imaging came into vogue, radionuclides and radiopharmaceuticals were developed that targeted select physiological processes, proteins, receptor analogs, antibody-antigen interactions, metabolites and specific metabolic pathways. In addition, with the advent of genomic imaging, targeted genomic therapy, and theranostics, a number of novel radiopharmaceuticals for the detection and therapy of specific tumor types based on unique biological and cellular properties of the tumor itself have been realized. However, molecular imaging and therapeutics as well as the concept of theranostics are yet to be fully realized. The purpose of this review article is to present an overview of the translational approaches to targeted molecular imaging with application to some naturally occurring animal models of human disease. © 2013 Published by Elsevier Inc.

    In human medicine, the information infrastructure that supports the knowledge translation processes of exchange, synthesis, dissemination, and application of the best clinical intervention research has developed significantly in the past 15 years, facilitating the uptake of research evidence by clinicians as well as the practice of evidence-based medicine. Seven of the key elements of this improved information infrastructure are clinical trial registries, research reporting standards, systematic reviews, organizations that support the production of systematic reviews, the indexing of clinical intervention research in MEDLINE, clinical search filters for MEDLINE, and point-of-care decision support information resources. The objective of this paper is to describe why these elements are important for evidence-based medicine, the key developments and issues related to these seven information infrastructure elements in human medicine, how these 7 elements compare with the corresponding infrastructure elements in veterinary medicine, and how all of these factors affect the translation of clinical intervention research into clinical practice. A focused search of the Ovid MEDLINE database was conducted for English language journal literature published between 2000 and 2010. Two bibliographies were consulted and selected national and international Web sites were searched using Google. The literature reviewed indicates that the information infrastructure supporting evidence-based veterinary medicine practice in all of the 7 elements reviewed is significantly underdeveloped in relation to the corresponding information infrastructure in human medicine. This lack of development creates barriers to the timely translation of veterinary medicine research into clinical practice and also to the conduct of both primary clinical intervention research and synthesis research.

  7. Herbal medicines for children: an illusion of safety?

    2001-04-01

    Herbal medicaments are in common use. In general, the judicious use of carefully selected and prepared herbal medications seems to cause few adverse effects and may be beneficial. However, toxic effects of these products have been reported with increasing frequency. Infants and children may be even more susceptible to some of the adverse effects and toxicity of these products because of differences in physiology, immature metabolic enzyme systems, and dose per body weight. Although information promoting the use of herbal medicine is widespread, true evidence-based information about the efficacy and safety of herbal medications is limited. Although the most conservative approach is to recommend against use of herbal medicine until such evidence is available, some patients are not receptive to this approach. A reasonable approach for health care providers may be to follow such use closely, assist in herbal therapeutic decisions, and monitor for adverse effects and interactions. This manuscript discusses general concepts about herbal medicines, public health implications, and a framework for mechanisms of adverse effects from the use of botanicals. Adverse effects and toxicity of selected herbal products, including Chinese herbal medicines, are presented. The authors propose a risk reduction approach in which physicians actively seek information about the use of complementary or alternative medicine while taking medical histories.

    The activity concentration of fallout radionuclides v.z., 238 Pu, 239+240 Pu, 241 Am, 137 Cs and 90 Sr has been measured in some species of multicellular marine algae, sea grass, coral fishes and shellfish, and surface sediments collected from the fringing reef at different locations along the Sudanese coast of the red sea.The measurements were carried out using alpha particle spectrometry, high resolution gamma spectrometry, gas flow proportional counter and liquid scintillation. In the sediments analyzed, the activity concentration averaged 2.65±1.3 ( 238 Pu), 47.96±26.3 ( 239+240 Pu), 19.1±6.5 ( 241 Am), 273±157 ( 137 Cs) and 140.8±73.9 ( 90 Sr) mBq/kg dry weight. Average activity concentrations(mBq/Kg dry weight) in marine algae from different locations were found to be 20.1±14.1, 21.6±13.3 and 8.5±3.8 ( 239+240 Pu), 6.2±4.0, 11.7±6.1 and 5.1±3.5 ( 241 Am) and 688±242, 868±713 and 116±14.8( 137 Cs) for brown, red and green algae, respectively. High levels of 137 Cs observed in brown and red algae seem to confirm that algae are responsive to the soluble phase of constituents in the ambient medium more than the elements associated to particulate matter. From the results obtained in this study, brown algae (cystoseria species) and red algae (lauranthia species) suggested their suitability to be used as a bio indicators. Activity concentrations of both 238 Pu, 239+240 Pu in fish are close to detection limits, while shellfish show values an order of magnitude higher relative to coral fish species. The lowest concentration for 239+240 Pu was met in the molluscs species tridacnica (2.4) and the highest value was met in the coral species favites. Committed effective dose (CED) from 137 Cs and 210 Po due to consumption of coral reef fishes was assessed from their respective activity concentration values measured in aforementioned 31 species of coral fishes using dose conversion factors (DRCFs). On the average, CED (μSv/y) values were found to be 0

    Full Text Available Background: Many natural products from plants have been recognized to exert anticancer activity. In this study, ethanolic extracts of selected medicinal herbs from Iranian flora including Alyssum homolocarpum Fisch. (from seeds, Urtica dioica L. (from aerial parts, Cichorium intybus L. (from roots and Solanum nigrum L. (from fruits, were evaluated for their cytotoxic effect on different cell lines.Methods: Cytotoxic effect of these extracts was studied on three different cancer cell lines; colon carcinoma (HT-29, colorectal adenocarcinoma (Caco-2 and breast ductal carcinoma (T47D. In addition, Swiss mouse embryo fibroblasts (NIH 3T3 were used as normal nonmalignant cells. MTT assay (3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide was utilized for calculating the cytotoxicity of extracts on cell lines.Results: Results showed the potent cytotoxic activity of U. dioica ethanolic extract against T47D cell line with IC50 value of 46.14±4.55 µg/ml. Other extracts showed poor activity with IC50>100 µg/ml.Conclusions: Cytotoxic activity recorded in the present study revealed high potential antiproliferative activity of U. dioica ethanolic extract against T47D cell line. The real IC50 values of this extract may be considerably lower than the IC50 measured in our study if its pharmacological active compounds become pure. The results emphasize the importance of studies on U. dioica ethanolic extract to characterize potential components as cytotoxic natural medicines.

    The objectives of this study were to determine the levels of the major and mineral nutrients, specially of trace elements, in some food items commonly consumed in Sudan, to assess the nutritional and energy values in these items and to compare the results of this work with local and international data.To achieve these objectives, food samples analyzed were collected from different localities in Sudan, and the samples were prepared for analysis using dry ashing and wet digestion. Moisture was determined using oven and freeze dryer. Proteins were determined by kjeldahl method. Fats were determined using ether extraction. Ash contents were determined using muffle furnace. Atomic absorption spectroscopy (AAS), X-ray flourescence spectroscopy (XRF), flame photometry and colorimetry techniques were employed for determination of elemental contents. The levels of food energy, moisture, carbohydrates, proteins, fats, crude fibre and ash contents were determined in legumes, cereals, oil seeds, flour and cereals products , vegetables, fruits, milk and milk products, and oil and fats. The elemental contents (Br, Ca, Co, Cu, Fe, Mg, Mn, P, Pb, Na, Rb, Sr and Zn). The Sudanese food items analyzed were found to contain considerable ranges of nutrients as follows: Food energy was found to be in its higest value (930 calg) in oil seeds and in the lowest range in vegetables (14.9-139 cal/g dry matter). Proteins contents were the the -ighest in oil seeds (17.4-27.7 g/100g of dry matter) and devoid in oils and fats. FAts contents were in the highest value (100% of dry matter) in oils and fats and in the lowest in vegetables (0.01-0.6 g/100g). Carbohydrates were in the highest range in cereals (73-79 g/100g of dry matter) and devoid in oils and fats. For the elemental contents the most significant elements have the following average: CA, CU and Fe were higher in fruits (4709, 21 and 633 ppm, respectively) and the lower in oils and fats (25, 2 and 11 ppm, respectively).

    The use of CT in medical diagnosis delivers radiation doses to patients that are higher than those from other radiological procedures. The aim of this study was to estimate radiation doses in abdomen CT examinations of patients in two Sudanese hospitals. Details were obtained from approximately 80 CT examinations and included all age groups ( adults and pediatric). The results from the two hospitals were compared with each other as well as with the IAEA guidance level for this particular investigation. The estimation of radiation doses were carried out by calculating volume dose index (CTD1vol), dose length product (DLP), doses to some organs of interest and effective dose (E) using the software program "CT EXPO V2.1". The study showed that the mean DLP of the one hospitals ASH is 1736.7 mGy.cm which is by far much higher than that for the other hospital NMDC which stands at 185.3 mGy.cm, as well as higher than the IAEA level which is 696 mGy.cm. The study showed that the mean CTD1vol for patients in ASH is 36.2 mGy which again higher than that for the other hospital which is 3.9 mGy and higher than the IAEA level which is 10.9 mGy calculating the effective dose for patients in the two hospitals reveals that the mean effective dose of patient in one hospital (ASH) is 26.25 mSv, which is quite high compared with other hospital (NMDC), which has the mean value of 2.8 mGv and also higher than the IAEA level from this investigation which is 7.6 mSv. Regarding organ doses, the study showed that organ doses in hospital ASH are always higher than that calculated in hospital NMDC and the highest doses in both hospital were delivered to the kidneys with mean values of 50.24 mGy and 5045 mGy for the two hospitals respectively. The study showed that there is an urgent need for optimizing patient doses in such CT examinations. This can be ensured by providing training and retraining for workers and conducting quality control measurements and preventive maintenance regularly so

    Within the competitive pharmacy market environment, community pharmacies are required to develop efficient marketing strategies based on contemporary information about consumer behavior in order to attract clients and develop customer loyalty. This study aimed to investigate the consumers' preferences concerning the selection of pharmacy and over-the-counter (OTC) medicines, and to identify customer segments in relation to these preferences. A cross-sectional study was conducted between February and March 2016 on a convenient quota sample of 300 participants recruited in the metropolitan area of Thessaloniki, Greece. The main instrument used for data collection was a structured questionnaire with close-ended, multiple choice questions. To identify customer segments, Two-Step cluster analysis was conducted. Three distinct pharmacy customer clusters emerged. Customers of the largest cluster (49%; 'convenience customers') were mostly younger consumers. They gave moderate to positive ratings to factors affecting the selection of pharmacy and OTCs; convenience, and previous experience and the pharmacist's opinion, received the highest ratings. Customers of the second cluster (35%; 'loyal customers') were mainly retired; most of them reported visiting a single pharmacy. They gave high ratings to all factors that influence pharmacy selection, especially the pharmacy's staff, and factors influencing the purchase of OTCs, particularly previous experience and the pharmacist's opinion. Customers of the smallest cluster (16%; 'convenience and price-sensitive customers') were mainly retired or unemployed with low to moderate education, and low personal income. They gave the lowest ratings to most of the examined factors; convenience among factors influencing pharmacy selection, whereas previous experience, the pharmacist's opinion and product price among those affecting the purchase of OTCs, received the highest ratings. The community pharmacy market comprised of distinct

    The extracts of nine selected Nigerian medicinal plants were investigated on Trypanosoma brucei brucei infected mice. The anti-inflammatory properties of hexane fraction of the most promising U. chamae extract was assessed by acute oedema of the mice paw model while the modulatory effect of the extract on Delayed-Type Hypersensitivity (DTH) response on in vivo leucocytes mobilization was evaluated. 'Dose-probing acute toxicity tests' established an oral and intraperitoneal LD50 for T. ivorensis stem bark as >1600 5000 mg/kg. Extracts of Khaya senegalensis, Harungana madagascariensis, Terminalia ivorensis, Curcuma longa, Ocimum gratissimum and Alcornea cordifolia showed weak anti-trypanosomal effect and did not exhibit significant clearance in parasitemia at the test dose administered compared with the positive control (Diminal®). However, the leaf extract of U. chamae and its hexane fraction demonstrated a significant response (P < 0.01). The fraction at 1000 mg/kg inhibited oedema by 107%. Uvaria. chamae demonstrated both antitrypanosomal and anti-inflammatory properties by increasing the survival time of infected mice due to reduction in parasitemia caused by T. brucei brucei.

    To assess the pharmaceutical sector to know whether people have access to essential medicines. The study was conducted in 20 public health clinics, five public district drug stores and 20 private retail pharmacies selected randomly in five different areas randomly selected (four states and a federal territory). The methodology used was adopted from the World Health Organization study protocol. The degree of attainment of the strategic pharmaceutical objectives of improved access is measured by a list of tested indicators. Access is measured in terms of the availability and affordability of essential medicines, especially to the poor and in the public sector. The first survey in the public health clinics and public district drug stores gathered information about current availability of essential medicines, prevalence of stock-outs and affordability of treatment (except drug stores). The second survey assessed affordability of treatment in public health clinics and private retail pharmacies. Availability, stock-out duration, percent of medicines dispensed, accessibility and affordability of key medicines. The average availability of key medicines in the public health clinics for the country was 95.4%. The average stock-out duration of key medicines was 6.5 days. However, average availability of key medicines in the public district drug stores was 89.2%; with an average stock-out duration of 32.4 days. Medicines prescribed were 100% dispensed to the patients. Average affordability for public health clinics was 1.5 weeks salary and for the private pharmacies, 3.7 weeks salary. The present pharmaceutical situation in the context of essential medicines list implementation reflected that the majority of the population in Malaysia had access to affordable essential medicines. If medicines need to be obtained from the private sector, they are hardly affordable. Although the average availability of essential medicines in Malaysia was high being more than 95.0%, in certain

    Full Text Available Free radical-mediated oxidation is often linked to various degenerative diseases. Biological substrates with lipids as major components are susceptible to oxygen-derived lipid peroxidation due to their composition. Lipid peroxide products act as biomarkers in evaluating the antioxidant potential of various plants and functional foods. The study focused on evaluation of the antioxidant potential of two extracts (methanol and 80% methanol of four medicinal plants, Andrographis paniculata, Costus speciosus, Canthium parviflorum, and Abrus precatorius, against Fenton reaction-mediated oxidation of three biological lipid substrates; cholesterol, low-density lipoprotein, and brain homogenate. The antioxidant activity of the extracts was measured by thiobarbituric acid reactive substances method. Also, the correlation between the polyphenol, flavonoid content, and the antioxidant activity in biological substrates was analyzed.

    The objective of this study were to determine the levels of the mineral nutrients, especially of trace elements, in some food items commonly consumed in Sudan and to compare the results of this work with local and international data. To achieve these objectives, food samples analyzed were collected from different localities in Sudan, and the samples were prepared for analysis by using dry ashing and wet digestion. Atomic absorption spectroscopy (AAS), x-ray fluorescence spectroscopy (XRF), flame photometry and colorimetry were used for the determination of the concentrations of elements in the samples, samples were ashed using muffle furnace at temperature 550 C. The quality of the data was verified by the analysis of standard reference materials TDD-ID and Hay-9. The levels of the elemental contents (Br, Ca, Co, Cu, Fe, Mg, Mn, P, Pb, Na, Rb, Sr, and Zn) were determined in legumes, cereals, oil seeds, flour and cereals products, vegetables, fruits, milk and milk products, egg, meats and fish, and oils and fats. The Sudanese food items analyzed were found to contain considerable ranges of nutrients as follows. Concentration levels for some of these elements Ca, Cu and Fe show values which were higher in fruits(4709, 21, and 633 ppm, respectively), and lower in vegetables (4094, 13, and 255 ppm, respectively). Pb and Mn were higher in vegetables (2 and 32 ppm, respectively) and lower in fruits (1 and 18 ppm) respectively). Na and Zn were higher in vegetables (3149 and 26 ppm, respectively) and lower fruits (269 and 13 ppm, respectively). The values obtained agree, in general, with data available from other countries. Variations were observed among certain varieties of food.(Author)

    The expiry of medicines in the supply chain is a serious threat to the already constrained access to medicines in developing countries. We investigated the extent of, and the main contributing factors to, expiry of medicines in medicine supply outlets in Kampala and Entebbe, Uganda. A cross-sectional survey of six public and 32 private medicine outlets was done using semi-structured questionnaires. The study area has 19 public medicine outlets (three non-profit wholesalers, 16 hospital stores/pharmacies), 123 private wholesale pharmacies and 173 retail pharmacies, equivalent to about 70% of the country's pharmaceutical businesses. Our findings indicate that medicines prone to expiry include those used for vertical programmes, donated medicines and those with a slow turnover. Awareness about the threat of expiry of medicines to the delivery of health services has increased. We have adapted training modules to emphasize management of medicine expiry for pharmacy students, pharmacists and other persons handling medicines. Our work has also generated more research interest on medicine expiry in Uganda. Even essential medicines expire in the supply chain in Uganda. Sound coordination is needed between public medicine wholesalers and their clients to harmonize procurement and consumption as well as with vertical programmes to prevent duplicate procurement. Additionally, national medicine regulatory authorities should enforce existing international guidelines to prevent dumping of donated medicine. Medicine selection and quantification should be matched with consumer tastes and prescribing habits. Lean supply and stock rotation should be considered.

    OBJECTIVES Like many other developing countries, South Africa provides free medicines through its public health care facilities. Recent policies encourage generic substitution in the private sector. This study explored South African consumer perceptions of drug quality and whether these perceptions influenced how people procured and used their medicines. METHODS The study was undertaken in Durban, Cape Town and Johannesburg in South Africa between December 2005 and January 2006. A combination of purposive and snowball sampling was used to recruit participants from low and middle socio-economic groups as well as the elderly and teenagers. Data were collected through 12 focus group discussions involving a total of 73 participants. Interviews were tape-recorded. Thematic analysis was performed on the transcripts. RESULTS Irrespective of socio-economic status, respondents described medicine quality in terms of the effect the medicine produced on felt symptoms. Generic medicines, as well as medicines supplied without charge by the state, were considered to be poor quality and treated with suspicion. Respondents obtained medicines from three sources: public sector hospitals and/or clinics, dispensing doctors and community pharmacies. Cost, avoidance of feeling 'second-class', receiving individualized care and choice in drug selection were the main determinants influencing their procurement behaviour. Selection of over-the-counter medicines was influenced by prior knowledge of products, through advertising and previous use. Participants perceived that they had limited influence on selection of prescription medicines. Generic substitution would be supported if the doctor, rather than the pharmacist, recommended it. CONCLUSIONS Our findings emphasize the importance of meaningful consumer involvement in the development of national medicines policies, and strategic campaigns targeting consumers and prescribers regarding the quality of generic and essential medicines.

    Full Text Available Background: Within the competitive pharmacy market environment, community pharmacies are required to develop efficient marketing strategies based on contemporary information about consumer behavior in order to attract clients and develop customer loyalty. Objectives: This study aimed to investigate the consumers’ preferences concerning the selection of pharmacy and over-the-counter (OTC medicines, and to identify customer segments in relation to these preferences. Methods: A cross-sectional study was conducted between February and March 2016 on a convenient quota sample of 300 participants recruited in the metropolitan area of Thessaloniki, Greece. The main instrument used for data collection was a structured questionnaire with close-ended, multiple choice questions. To identify customer segments, Two-Step cluster analysis was conducted. Results: Three distinct pharmacy customer clusters emerged. Customers of the largest cluster (49%; ‘convenience customers’ were mostly younger consumers. They gave moderate to positive ratings to factors affecting the selection of pharmacy and OTCs; convenience, and previous experience and the pharmacist’s opinion, received the highest ratings. Customers of the second cluster (35%; ‘loyal customers’ were mainly retired; most of them reported visiting a single pharmacy. They gave high ratings to all factors that influence pharmacy selection, especially the pharmacy’s staff, and factors influencing the purchase of OTCs, particularly previous experience and the pharmacist’s opinion. Customers of the smallest cluster (16%; ‘convenience and price-sensitive customers’ were mainly retired or unemployed with low to moderate education, and low personal income. They gave the lowest ratings to most of the examined factors; convenience among factors influencing pharmacy selection, whereas previous experience, the pharmacist’s opinion and product price among those affecting the purchase of OTCs

    Mali is one of the countries in West Africa where the health system rely the most on traditional medicine. The healers are mainly using medicinal plants for their treatments. The studies performed being the basis for this review is of importance as they will contribute to sustaining the traditional knowledge. They contribute to evaluate and improve locally produced herbal remedies, and the review gives also an overview of the plant preparations that will have the most potential to be evaluated for new Improved Traditional Medicines. The aim of this review is to give an overview of the studies performed related to medicinal plants from Mali in the period 1995-2015. These studies include ethnopharmacology, chemistry and biological studies of the plants that were chosen based on our interviews with the healers in different regions of Mali, and contribute to sustainable knowledge on the medicinal plants. The Department of Traditional Medicine, Bamako, Mali, is responsible for registering the knowledge of the traditional healers on their use of medicinal plants and also identifying compounds in the plants responsible for the bioactivities claimed. The studies reported aimed at getting information from the healers on the use of medicinal plants, and study the biology and chemistry of selected plants for the purpose of verifying the traditional use of the plants. These studies should form the basis for necessary knowledge for the development of registered Improved Traditional Medicines in Mali. The healers were the ethnopharmacological informants. Questions asked initially were related to wound healing. This was because the immune system is involved when wounds are healed, and additionally the immune system is involved in the majority of the illnesses common in Mali. Based on the results of the interviews the plant material for studies was selected. Studies were performed on the plant parts the healers were using when treating their patients.

    Full Text Available Survey data show that the use of generic medicines in Indonesia is relatively very small, which only amounted 7%. This is due to lack of knowledge and poor perceptions towards generic medicines. Knowledge level and perceptions towards generic medicines are inflenced by community characteristics and information resource regarding generic medicines. The aim of this study was to determine the association between community characteristic and information resources with knowledge level and perception towards generic medicines. This study was an analytical survey with cross-sectional descriptive approach on 142 selected respondents who were fulfi inclusion and exclusion criteria. This study was conducted in June 2014 at several randomly selected locations on Singkawang City. The study show that 76 respondents (53.5% had inadequate knowledge and 123 respondents (86.6% had a good perception towards generic medicines. There is signifiant relationship between ethnicity (p=0.000 and information resources (p=0.009 with knowledge level regarding generic medicines at signifiance level of p<0.05. Although good perceptions were noted among the respondents, widespread dissemination of information regarding generic medicines should be continued to increase generic medicines used.

    Full Text Available Cancer is one of the leading causes of death in the United States, and more than 1.5 million new cases and more than 0.5 million deaths were reported during 2010 in the United States alone. Following completion of the sequencing of the human genome, substantial progress has been made in characterizing the human epigenome, proteome, and metabolome; a better understanding of pharmacogenomics has been developed, and the potential for customizing health care for the individual has grown tremendously. Recently, personalized medicine has mainly involved the systematic use of genetic or other information about an individual patient to select or optimize that patient’s preventative and therapeutic care. Molecular profiling in healthy and cancer patient samples may allow for a greater degree of personalized medicine than is currently available. Information about a patient’s proteinaceous, genetic, and metabolic profile could be used to tailor medical care to that individual’s needs. A key attribute of this medical model is the development of companion diagnostics, whereby molecular assays that measure levels of proteins, genes, or specific mutations are used to provide a specific therapy for an individual’s condition by stratifying disease status, selecting the proper medication, and tailoring dosages to that patient’s specific needs. Additionally, such methods can be used to assess a patient’s risk factors for a number of conditions and to tailor individual preventative treatments. Recent advances, challenges, and future perspectives of personalized medicine in cancer are discussed.

    The essential traditional Chinese medicines (ETCM) are the characteristics of our National Essential Medicine List (NEML) and we should give full play to its unique advantage. The essential medicines of ETCM are specific, but also have dual characters, namely efficacy and ADRs. Although ADRs cannot be avoided, we can make efforts to control some conditions to minimize the possibility of ADRs. It is significant to give suggestions to reduce ADRs of ETCM under the ETCM system by analyzing the possibility of ADRs during ETCM selection, production distribution and use. This research focuses on ETCM, and the conclusion is also applicable to common traditional Chinese medicines. Copyright© by the Chinese Pharmaceutical Association.

    Nowadays, herbal medicines are widely used by most of the people, including the pre-surgical population. These medicines may pose numerous challenges during perioperative care. The objective of the current literature review is to dwell upon the impact of the use of herbal medicines during the perioperative period, and to review the strategies for managing their perioperative use. The data was generated from various articles of different journals, text books, web source, including, Entrez Pubmed, Medscape, WebMD, and so on. Selected only those herbal medicines for which information on, safety, usage, and precautions during the perioperative period was available. Thereafter, the information about safety, pharmacokinetics, and pharmacodynamics from selected literature was gathered and analyzed. The whole review focused on the fact that these commonly used alternative medicines could sometimes pose as a concern during the perioperative period, in various ways. These complications could be due to their direct action, pharmacodynamic effect, or pharmacokinetic effect. In view of the serious impacts of herbal medicine usage in perioperative care, the anesthesiologist should take a detailed history, especially stressing on the use of herbal medicine during the preoperative anesthetic assessment. The anesthesiologist should also be aware of the potential perioperative effects of those drugs. Accordingly, steps should to be taken to prevent, recognize, and treat the complications that may arise due to their use or discontinuation.

    The history of observation medicine has paralleled the rise of emergency medicine over the past 50 years to meet the needs of patients, emergency departments, hospitals, and the US health care system. Just as emergency departments are the safety net of the health system, observation units are the safety net of emergency departments. The growth of observation medicine has been driven by innovations in health care, an ongoing shift of patients from inpatient to outpatient settings, and changes in health policy. These units have been shown to provide better outcomes than traditional care for selected patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    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

    Buruli ulcer (BU) is the third most prevalent mycobacteriosis, after tuberculosis and leprosy. The currently recommended combination of rifampicin-streptomycin suffers from side effects and poor compliance, which leads to reliance on local herbal remedies. The objective of this study was to investigate the antimycobacterial properties and toxicity of selected medicinal plants. Sixty-five extracts from 27 plant species were screened against Mycobacterium ulcerans and Mycobacterium smegmatis, using the Resazurin Microtiter Assay (REMA). The cytotoxicity of promising extracts was assayed on normal Chang liver cells by an MTT assay. Twenty five extracts showed activity with minimal inhibitory concentration (MIC) values ranging from 16 µg/mL to 250 µg/mL against M. smegmatis, while 17 showed activity against M. ulcerans with MIC values ranging from 125 µg/mL to 250 µg/mL. In most of the cases, plant extracts with antimycobacterial activity showed no cytotoxicity on normal human liver cells. Exception were Carica papaya, Cleistopholis patens, and Polyalthia suaveolens with 50% cell cytotoxic concentrations (CC50) ranging from 3.8 to 223 µg/mL. These preliminary results support the use of some West African plants in the treatment of Buruli ulcer. Meanwhile, further studies are required to isolate and characterize the active ingredients in the extracts.

    Only recently, regulations on the names of medicines were developed. Regulations are mainly focused on avoiding the approval of medicine names that may be confusing to others. Furthermore, legal requirements do not include testing for human factors, such as potential users' preferences. To develop a set of new brand names of medicines, to determine subjects' preferred names, and to evaluate if the linguistic features of these names were related to subjects' preferences. Forty-six new names linguistically equivalent to the Portuguese brand names of medicines were developed. A panel of 13 postgraduates on linguistic studies were purposively enrolled. Participants were required to select and categorize the 6 most preferred names. From the 29 selected names: 62.1% ended in consonants, 65.5% contained at least one syllable of the CVC type, and 62.1% presented final stress. Considering these 3 linguistic features, there were statistically significant differences between the preferred and underpreferred names: χ 2 = 4.572, P = .032; χ 2 = 5.599, P = .018; and χ 2 = 4.572; P = .032, respectively. Some linguistic features of the evaluated names were related to subjects' preferences. Tests on subjects' preferences about the names of medicines may provide additional safety features addressed by the present regulations.

    Research on resident attrition rates suggests that medical students would benefit from more comprehensive career advising programs during medical school. Responding to this need, students and administrators at the Vanderbilt University School of Medicine (Vanderbilt) introduced a broad Careers in Medicine (CiM) program in 2005 to complement the CiM resources offered by the Association of American Medical Colleges (AAMC). In this article, the authors detail the Vanderbilt CiM program's four core components: career-related events, an elective course, specialty interest groups, and career advising. The authors discuss the program's implementation and its student-led organizational structure, and they provide a critical assessment of important lessons learned. Using data from internal satisfaction surveys and the AAMC's Medical School Graduation Questionnaire (GQ), they demonstrate the success of Vanderbilt's career counseling efforts. According to recent GQ data, Vanderbilt ranks above the U.S. medical school average on graduating students' ratings of overall satisfaction with career services and of the usefulness of key programming. The authors present this description of the Vanderbilt CiM model as a framework for other medical schools to consider adopting or adapting as they explore options for expanding their own career counseling services.

    Precision medicine is a new paradigm that combines diagnostic, imaging, and analytical tools to produce accurate diagnoses and therapeutic interventions tailored to the individual patient. This approach stands in contrast to the traditional "one size fits all" concept, according to which researchers develop disease treatments and preventions for an "average" patient without considering individual differences. The "one size fits all" concept has led to many ineffective or inappropriate treatments, especially for pathologies such as Alzheimer's disease and cancer. Now, precision medicine is receiving massive funding in many countries, thanks to its social and economic potential in terms of improved disease prevention, diagnosis, and therapy. Bioanalytical chemistry is critical to precision medicine. This is because identifying an appropriate tailored therapy requires researchers to collect and analyze information on each patient's specific molecular biomarkers (e.g., proteins, nucleic acids, and metabolites). In other words, precision diagnostics is not possible without precise bioanalytical chemistry. This Trend article highlights some of the most recent advances, including massive analysis of multilayer omics, and new imaging technique applications suitable for implementing precision medicine. Graphical abstract Precision medicine combines bioanalytical chemistry, molecular diagnostics, and imaging tools for performing accurate diagnoses and selecting optimal therapies for each patient.

    A constitutional guarantee of access to essential medicines has been identified as an important indicator of government commitment to the progressive realization of the right to the highest attainable standard of health. The objective of this study was to evaluate provisions on access to essential medicines in national constitutions, to identify comprehensive examples of constitutional text on medicines that can be used as a model for other countries, and to evaluate the evolution of constitutional medicines-related rights since 2008. Relevant articles were selected from an inventory of constitutional texts from WHO member states. References to states' legal obligations under international human rights law were evaluated. Twenty-two constitutions worldwide now oblige governments to protect and/or to fulfill accessibility of, availability of, and/or quality of medicines. Since 2008, state responsibilities to fulfill access to essential medicines have expanded in five constitutions, been maintained in four constitutions, and have regressed in one constitution. Government commitments to essential medicines are an important foundation of health system equity and are included increasingly in state constitutions.

    The aim of present was to document indigenous knowledge of medicinal plants traditionally used by inhabitants of Rawalakot Azad Kashmir and to screen selected medicinal plants for their antibacterial potential. Several field surveys were conducted to document indigenous knowledge of medicinal plants through interviews from local inhabitants during 2010-2013. During the study, 58 plant species, belonging to 37 families, were identified and their medicinal uses were recorded. Ethnobotanical data indicates that inhabitants of Rawalakot use medicinal plant mainly for the treatment of stomach, liver and sexual disorders. Usually fresh plant materials were used for medicinal preparations and administrated orally. Among all the species studied, three most frequently used medicinal plants Achillea millefolium, Berberis lycium and Zanthoxylum armatum were screened for their antibacterial potential by using disc diffusion method. The crude aqueous, petroleum ether and ethanolic extracts were found to be very active against selected bacterial strains. The present study contributes significantly to the medicinal plant knowledge and shows that medicinal plant knowledge is deteriorating among younger generations. Therefore, further research is needed to document indigenous knowledge, to find conservation status of medicinal plant species and to find antimicrobial compounds for more sophisticated usage of medicinal plants in future.

    This study aimed at synthesizing funding opportunities in the field of family medicine by determining the number of family medicine projects, as well as number of project leaderships and/ or participations by each country. This was done in order to encourage inclusion of physicians in countries with underdeveloped research networks in successful research networks or to encourage them to form new ones. We searched the Community Research and Development Information Service project database in February 2013. Study covered the period from years 1992 - 2012, selecting the projects within the field of general/family medicine. The search was conducted in February 2013. First search conducted in the CORDIS database came up with a total of 466 projects. After excluding 241 projects with insufficient data, we analysed 225 remaining projects; out of those, 22 (9.8%) were in the field of family medicine and 203 (90.2%) were from other fields of medicine. Sorted by the number of projects per country, Dutch institutions had the highest involvement in family medicine projects and were partners or coordinators in 18 out of 22 selected projects (81.8%), followed by British institutions with 15 (68.8%), and Spanish with 10 projects (45.5%). Croatia was a partner in a single FP7 Health project. Research projects in family medicine funded by the European Union show significant differences between countries. Constant and high-quality international cooperation in family medicine is the prerequisite for improvement and development of scientific research and the profession.

    Inflammatory disorders are common in modern life, and medicinal plants provide an interesting source for new compounds bearing anti-inflammatory properties. In this regard, Brazilian medicinal plants are considered to be a promising supply of such compounds due to their great biodiversity. To undertake a review on Brazilian medicinal plants with corroborated anti-inflammatory activities by selecting data from the literature reporting the efficacy of plants used in folk medicine as anti-inflammatory, including the mechanisms of action of their extracts and isolated compounds. A search in the literature was undertaken by using the following Web tools: Web of Science, SciFinder, Pub-Med and Science Direct. The terms 'anti-inflammatory' and 'Brazilian medicinal plants' were used as keywords in search engine. Tropicos and Reflora websites were used to verify the origin of the plants, and only the native plants of Brazil were included in this review. The publications reporting the use of well-accepted scientific protocols to corroborate the anti-inflammatory activities of Brazilian medicinal plants with anti-inflammatory potential were considered. We selected 70 Brazilian medicinal plants with anti-inflammatory activity. The plants were grouped according to their anti-inflammatory mechanisms of action. The main mechanisms involved inflammatory mediators, such as interleukins (ILs), nuclear factor kappa B (NF-κB), prostaglandin E2 (PGE2), cyclooxygenase (COX) and reactive oxygen species (ROS). The collected data on Brazilian medicinal plants, in the form of crude extract and/or isolated compounds, showed significant anti-inflammatory activities involving different mechanisms of action, indicating Brazilian plants as an important source of anti-inflammatory compounds.

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

    Precision medicine in oncology focuses on identifying which therapies are most effective for each patient based on genetic characterization of the cancer. Traditional chemotherapy is cytotoxic and destroys all cells that are rapidly dividing. The foundation of precision medicine is targeted therapies and selecting patients who will benefit most from these therapies. One of the newest aspects of precision medicine is liquid biopsy. A liquid biopsy includes analysis of circulating tumor cells, cell-free nucleic acid, or exosomes obtained from a peripheral blood draw. These can be studied individually or in combination and collected serially, providing real-time information as a patient's cancer changes. Copyright © 2016 Elsevier Inc. All rights reserved.

    Actinobacteria are a prolific source of antibiotics. Since the rate of discovery of novel antibiotics is decreasing, actinobacteria from unique environments need to be explored. In particular, actinobacterial biocontrol strains from medicinal plants need to be studied as they can be a source of potent antibiotics. We combined culture-dependent and culture-independent methods in analyzing the actinobacterial diversity in the rhizosphere of seven traditional medicinal plant species from Panxi, China, and assessed the antimicrobial activity of the isolates. Each of the plant species hosted a unique set of actinobacterial strains. Out of the 64 morphologically distinct isolates, half were Streptomyces sp., eight were Micromonospora sp., and the rest were members of 18 actinobacterial genera. In particular, Ainsliaea henryi Diels. hosted a diverse selection of actinobacteria, although the 16S ribosomal RNA (rRNA) sequence identity ranges of the isolates and of the 16S rRNA gene clone library were not congruent. In the clone library, 40% of the sequences were related to uncultured actinobacteria, emphasizing the need to develop isolation methods to assess the full potential of the actinobacteria. All Streptomyces isolates showed antimicrobial activity. While the antimicrobial activities of the rare actinobacteria were limited, the growth of Escherichia coli, Verticillium dahliae, and Fusarium oxysporum were inhibited only by rare actinobacteria, and strains related to Saccharopolyspora shandongensis and Streptosporangium roseum showed broad antimicrobial activity.

    Full Text Available Malaria, leishmaniasis and human African trypanosomiasis continue to be major public health problems in need of new and more effective drugs. The aim of this study was to evaluate in vitro antiprotozoal activity of twenty endemic medicinal plants collected from the island of Soqotra in the Indian Ocean. The plant materials were extracted with methanol and tested for antiplasmodial activity against erythrocytic schizonts of Plasmodium falciparum, for antileishmanial activity against intracellular amastigotes of Leishmania infantum and for antitrypanosomal activity against intracellular amastigotes of Trypanosoma cruzi and free trypomastigotes of T. brucei. To assess selectivity, cytotoxicity was determined against MRC-5 fibroblasts. Selective activity was obtained for Punica protopunica against Plasmodium (IC50 2.2 µg/mL while Eureiandra balfourii and Hypoestes pubescens displayed activity against the three kinetoplastid parasites (IC50 < 10 µg/mL. Acridocarpus socotranus showed activity against T. brucei and T. cruzi (IC50 3.5 and 8.4 µg/mL. Ballochia atrovirgata, Dendrosicycos socotrana, Dracaena cinnabari and Euphorbia socotrana displayed non-specific inhibition of the parasites related to high cytotoxicity.

    Aqueous extracts of three medicinal plants used in Malaysian traditional medicine for the treatment of diabetes were investigated. The nuts of Areca cathecu, leaves of Lagerstroemia speciosa and Ficus deltoidea were each extracted by boiling in distilled water. The aqueous extracts were filtered and the filtrates were then spray dried. Their biological evaluation was conducted to determine their blood glucose lowering effect in normoglycaemic and alloxan-induced diabetic rats. Commercially available antidiabetic drug, glybenclamide was used as positive control. Toxicity of the extracts was carried out using the brine shrimp lethality assay and in vivo acute toxicity test in rats. Aqueous extracts of all the plants studied showed significant reduction in blood glucose level up to 50% in rats over a period of 3 to 4 weeks. The largest reduction in blood glucose levels was exhibited by the aqueous extracts of the Lagestroemia speciosa, followed by the Ficus deltoidea and Areca cathecu. There was no evidence of toxicity of the extracts against the brine shrimp (up to 4,000 μg/ml) and in rats (up to 0.2% body weight). (Author)

    Traditional medicinal plants have been used as an alternative medicine in many parts of the world, including Ethiopia. There are many documented scientific reports on antimicrobial activities of the same. To our knowledge, however, there is no report on the anti-Quorum Sensing (Quorum Quenching, QQ) potential of traditional Ethiopian medicinal plants. As many of the opportunistic pathogenic bacteria depend on Quorum Sensing (QS) systems to coordinate their virulence expression, interference with QS could be a novel approach to control bacterial infections. Thus, the aim of this study was to evaluate selected medicinal plants from Ethiopia for their antimicrobial activities against bacterial and fungal pathogens; and to assess the interference of these plant extracts with QS of bacteria. Antimicrobial activities of plant extracts (oil, resins and crude extracts) were evaluated following standard agar diffusion technique. The minimum inhibitory concentrations (MIC) of potent extracts were determined using 96 well micro-titer plates and optical densities were measured using an ELISA Microplate reader. Interference with Quorum Sensing activities of extracts was determined using the recently established E. coli based reporter strain AI1-QQ.1 and signaling molecule N-(ß-ketocaproyl)-L-homoserine lactone (3-oxo-C6-HSL). Petroleum ether extract of seed of Nigella sativa exhibited the highest activity against both the laboratory isolated Bacillus cereus [inhibition zone (IZ), 44 ± 0.31 mm] and B. cereus ATCC 10987 (IZ, 40 ± 2.33 mm). Similarly, oil extract from mature ripe fruit husk of Aframomum corrorima and mature unripe fruit of A. corrorima revealed promising activities against Candida albicans ATCC 90028 (IZ, 35 ± 1.52 mm) and Staphylococcus aureus DSM 346 (IZ, 25 ± 1.32 mm), respectively. Antimicrobial activities of oil extract from husk of A. corrorima and petroleum ether extract of seed of N. sativa were significantly higher than that of

  13. Availability, diversification and versatility explain human selection of introduced plants in Ecuadorian traditional medicine.

    Directory of Open Access Journals (Sweden)

    G Hart

    Full Text Available Globally, a majority of people use plants as a primary source of healthcare and introduced plants are increasingly discussed as medicine. Protecting this resource for human health depends upon understanding which plants are used and how use patterns will change over time. The increasing use of introduced plants in local pharmacopoeia has been explained by their greater abundance or accessibility (availability hypothesis, their ability to cure medical conditions that are not treated by native plants (diversification hypothesis, or as a result of the introduced plants' having many different simultaneous roles (versatility hypothesis. In order to describe the role of introduced plants in Ecuador, and to test these three hypotheses, we asked if introduced plants are over-represented in the Ecuadorian pharmacopoeia, and if their use as medicine is best explained by the introduced plants' greater availability, different therapeutic applications, or greater number of use categories. Drawing on 44,585 plant-use entries, and the checklist of >17,000 species found in Ecuador, we used multi-model inference to test if more introduced plants are used as medicines in Ecuador than expected by chance, and examine the support for each of the three hypotheses above. We find nuanced support for all hypotheses. More introduced plants are utilized than would be expected by chance, which can be explained by geographic distribution, their strong association with cultivation, diversification (except with regard to introduced diseases, and therapeutic versatility, but not versatility of use categories. Introduced plants make a disproportionately high contribution to plant medicine in Ecuador. The strong association of cultivation with introduced medicinal plant use highlights the importance of the maintenance of human-mediated environments such as homegardens and agroforests for the provisioning of healthcare services.

    An understanding of student decision-making when selecting an emergency medicine (EM) training program is essential for program directors as they enter interview season. To build upon preexisting knowledge, a survey was created to identify and prioritize the factors influencing candidate decision-making of U.S. medical graduates. This was a cross-sectional, multi-institutional study that anonymously surveyed U.S. allopathic applicants to EM training programs. It took place in the 3-week period between the 2011 National Residency Matching Program (NRMP) rank list submission deadline and the announcement of match results. Of 1,525 invitations to participate, 870 candidates (57%) completed the survey. Overall, 96% of respondents stated that both geographic location and individual program characteristics were important to decision-making, with approximately equal numbers favoring location when compared to those who favored program characteristics. The most important factors in this regard were preference for a particular geographic location (74.9%, 95% confidence interval [CI] = 72% to 78%) and to be close to spouse, significant other, or family (59.7%, 95% CI = 56% to 63%). Factors pertaining to geographic location tend to be out of the control of the program leadership. The most important program factors include the interview experience (48.9%, 95% CI = 46% to 52%), personal experience with the residents (48.5%, 95% CI = 45% to 52%), and academic reputation (44.9%, 95% CI = 42% to 48%). Unlike location, individual program factors are often either directly or somewhat under the control of the program leadership. Several other factors were ranked as the most important factor a disproportionate number of times, including a rotation in that emergency department (ED), orientation (academic vs. community), and duration of training (3-year vs. 4-year programs). For a subset of applicants, these factors had particular importance in overall decision-making. The vast majority

    To assess the effects of extraction methods on antioxidant activities of selected Indian medicinal flora. Different parts of plants were extracted by hydroalcoholic and decoction methods using water and various concentrations of methanol (ME) viz. 75%, 50% and 25% ME. The antioxidant activity of all the different extracts was evaluated using two different antioxidant assays viz. 2,2-diphenyl-1-picryl hydrazyl (DPPH) free radical scavenging assay and superoxide anion radical scavenging assay. Total phenol and flavonoid content was also estimated. The results showed that the extracting solvent significantly altered the antioxidant property estimations of screened plants. High correlations between phenolic compositions and antioxidant activities of extracts were observed. High levels of antioxidant activities were detected in Manilkara zapota (M. zapota) as compared with other screened plants. The results obtained appear to confirm the effect of different methods on extraction of antioxidants and antioxidant property of M. zapota.

    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

    To suggest a scheme of decision making on pricing for medicines that are part of Free Regulated Regime, a regulation way of the pharmaceutical pricing policy in Colombia. It includes two regulation tools: international reference prices and a cost minimization analysis methodology. Following the current pricing policy, international reference prices were built with data from five countries for selected medicines, which are under Free Regulated Regime. The cost minimization analysis methodology includes selection of those medicines under Free Regulated Regime with possible comparable medicines, selection of comparable medicines, and treatment costs evaluation. As a result of the estimate of International Reference Prices, four medicines showed in the domestic pharmaceutical market a bigger price than the Reference Price. A scheme of decision-making was design containing two possible regulation tools for medicines that are part of Free Regulated Regime: estimate of international reference prices and cost minimization analysis methodology. This diagram would be useful to assist the pricing regulation of Free Regulated Regime in Colombia. As present results shows, international reference prices make clear when domestic prices are higher than those of reference countries. In the current regulation of pharmaceutical prices in Colombia, the international reference price has been applied for four medicines. Would be suitable to extend this methodology to other medicines of high impact on the pharmaceutical expenditure, in particular those covered by public funding. The availability of primary sources about treatment costs in Colombia needs to be improved as a requirement to develop pharmaco-economic evidence. SISMED is an official database that represents an important primary source of medicines prices in Colombia. Nevertheless, having into account that SISMED represents an important advantage of transparency in medicines prices, it needs to be improved in quality and data

    The possible ways to optimise the relation between diagnostic information and patient absorbed dose differ between nuclear medicine and X ray imaging. In nuclear medicine, very little has been done to find an optimal dosage of radiopharmaceuticals. Current nuclear medicine methods are discussed in the light of the recent ICRP Publications and the new EU Patient Directive. The paper also discusses how reference levels for administered activity may be derived from patient studies. In order to eliminate the most inappropriate choices (too low or too high activities), knowledge of the current statistical distribution of administered activities may be helpful. Different methods to estimate the amount of activity that should be administered to children of various body sizes to guarantee the same image quality as for adults are also discussed. Examples of current activity levels for common nuclear medicine procedures, indicating the state of the practice, are given. (author)

    Full Text Available Information about medicinal plants that is available in text documents is generally quite easy to access, however, one needs some efforts to use it. This research was aimed at utilizing crucial information taken from a text document to identify the family of several species of medicinal plants using a heuristic approach, i.e. genetic programming. Each of the species has its unique features. The genetic program puts the characteristics or special features of each family into a tree form. There are a number of processes involved in the investigated method, i.e. data acquisition, booleanization, grouping of training and test data, evaluation, and analysis. The genetic program uses a training process to select the best individual, initializes a generate-rule process to create several individuals and then executes a fitness evaluation. The next procedure is a genetic operation process, which consists of tournament selection to choose the best individual based on a fitness value, the crossover operation and the mutation operation. These operations have the purpose of complementing the individual. The best individual acquired is the expected solution, which is a rule for classifying medicinal plants. This process produced three rules, one for each plant family, displaying a feature structure that distinguishes each of the families from each other. The genetic program then used these rules to identify the medicinal plants, achieving an average accuracy of 86.47%.

    Publications linking hepatotoxicity to the use of herbal preparations are escalating. Herbal teas, traditional Chinese medicines (TCMs) and dietary supplements have been shown to contain pyrrolizidine alkaloids (PAs). Acute PA toxicosis of the liver can result in sinusoidal-obstruction syndrome, also known as veno-occlusive disease (VOD). This paper describes a sensitive and robust method for the detection of targeted PAs and their N-oxides (PANOs) in herbal products (selected herbal teas and TCMs) sourced within Ireland. The sample preparation includes a simple acidic extraction with clean-up via solid-phase extraction (SPE). Sample extracts were accurately analysed by using LC-ESI-MS/MS applying for the first time a pentafluorophenyl (PFP) core-shell column to the chromatographic separation of PAs and PANOs. The method was validated for selectivity, taking into consideration matrix effects, specificity, linearity, precision and trueness. Limits of detection (LOD) and limits of quantitation (LOQ) were quantified for all PAs and PANOs ranging from 0.4 to 1.9 µg kg⁻¹ and from 1.3 to 6.3 µg kg⁻¹, respectively. In this study 10 PAs and four PANOs were targeted because they are commercially available as reference standards. Therefore, this study can only report the levels of these PAs and PANOs analysed in the herbal teas and TCMs. The results reported represent the minimum levels of PAs and PANOs present in the samples analysed; commercially available herbal teas (n = 18) and TCMs (n = 54). A total of 50% herbal teas and 78% Chinese medicines tested positive for one or more PAs and/or PANOs included within this study, ranging from 10 to 1733 and from 13 to 3668 µg kg⁻¹, respectively.

  7. Balancing personalized medicine and personalized care.

    The current description of personalized medicine by the National Institutes of Health is "the science of individualized prevention and therapy." Although physicians are beginning to see the promise of genetic medicine coming to fruition, the rapid pace of sequencing technology, informatics, and computer science predict a revolution in the ability to care for patients in the near future. The enthusiasm expressed by researchers is well founded, but the expectations voiced by the public do not center on advancing technology. Rather, patients are asking for personalized care: a holistic approach that considers physical, mental, and spiritual well-being. This perspective considers psychological, religious, and ethical challenges that may arise as the precision of preventive medicine improves. Psychological studies already highlight the barriers to single gene testing and suggest significant barriers to the predictive testing envisioned by personalized medicine. Certain religious groups will likely mount opposition if they believe personalized medicine encourages embryo selection. If the technology prompts cost-containment discussions, those concerned about the sanctity of life may raise ethical objections. Consequently, the availability of new scientific developments does not guarantee advances in treatment because patients may prove unwilling to receive and act on personalized genetic information. This perspective highlights current efforts to incorporate personalized medicine and personalized care into the medical curriculum, genetic counseling, and other aspects of clinical practice. Because these efforts are generally independent, the authors offer recommendations for physicians and educators so that personalized medicine can be implemented in a manner that meets patient expectations for personalized care.

    The objectives of this study were to determine the levels of the mineral nutrients, especially of trace elements, in some food items commonly consumed in sudan and to compare the results of this work with local and inter nation data. to achieve these objectives.Food samples were collected from different localities in sudan, and the samples were prepared for analysis using dry ashing and wet digestion. Atomic absorption spectroscopy (Aas), X-ray florescence spectroscopy (XRF), flame photometry and colorimetry were used for the determination of the concentrations of elements in the samples. Samples were ashed using muffle furnace at temperature 55 degree C. The quality of the data was verified by the analysis of standard reference materials TDD-Id and hay-9. The levels of the elemental contents (Br,Ca,Co,Cu,Fe,Mg,Mn,P,Pb,Na,Rb,Sr, and Zn) were determined in legumes, cereals, oil seeds, flour and cereal products, vegetables, fruits, milk and milk products, egg, meats and fish, and oils and fats. The sudanese food items analyzed were found to contain considerable ranges of nutrients as follows:-concentration levels for some of these elements Ca, Cu and Fe show values which were higher in fruits (4709,21, and 633 ppm, respectively), and lower in oils and fat s (25, 2, and 11 ppm, respectively). Pb and Mn were higher in flour and cereals products (4 and 34 ppm, respectively) and lower in fruits (1 ppm) and meats and fish (1 ppm and 4 ppm, respectively ). Na and Zn were higher in flour and cereals products and legumes (4970 and 39 ppm, respectively). The values obtained agree, in general, with data available from other countries. Variations were observed among certain varieties of food. (Author)

    Worldwide, an estimated 200 million girls and women have been subjected to female genital cutting. Female genital cutting is defined as an intentional injury to the female genitalia without medical justification. The practice occurs in at least 29 countries in Africa, the Middle East, and Asia. In addition, globalization and migration have brought immigrants from countries where cutting is commonly practiced to countries where cutting is not traditionally practiced and may even be illegal. In countries receiving immigrants, governments and development agencies would like to know if girls with parents who immigrated from practicing countries are at risk of being cut. Risk assessments, for example, could help governments identify the need for programs promoting the abandonment of cutting among immigrants. Extrapolating from the prevalence and incidence rates in practicing countries, however, is generally not sufficient to guarantee a valid estimate of risk in immigrant populations. In particular, immigrants might differ from their counterparts in the country of origin in terms of attitudes toward female genital cutting. Attitudes can differ because migrants represent a special sample of people from the country of origin or because immigrants acculturate after arriving in a new country. To examine these possibilities, we used a fully anonymous, computerized task to elicit implicit attitudes toward female genital cutting among Sudanese immigrants living in Switzerland and Sudanese people in Sudan. Results show that Sudanese immigrants in Switzerland were significantly more positive about uncut girls than Sudanese in Sudan, and that selective migration out of Sudan likely contributed substantially to this difference. We conclude by suggesting how our method could potentially be coupled with recent efforts to refine extrapolation methods for estimating cutting risk among immigrant populations. More broadly, our results highlight the need to better understand how

In the Nile painting company site, calcium, cobalt, nickel and lead exhibited high levels of concentration, whilst chromium, and copper displayed relatively high values with respect to their levels in the control site (Tutti Island). Iron exhibited a level nearly identical to that measured at the control site. No emission of zinc was monitored. In Battery Charging Shop site, Iron and lead, displayed the highest levels recorded, and calcium, chromium, copper, exhibited concentrations relatively high than the corresponding levels in the control site. Cobalt, nickel, and zinc have not been detected. The same trending was found in Khartoum University Printing Press site, with the exception that the level of iron is relatively high with respect to that of control site. In Mirghany Workshop site, calcium, iron, nickel, and zinc measured the highest values. Chromium, copper, and lead measured relatively high values with respect to their concentrations in the control site. No emission of cobalt was monitored. The average concentrations of calcium, iron, copper, and lead in Burri Power Station were nearly the same with that control site. Chromium, cobalt, nickel, and zinc, however, were not detected. In the indoor aerosol of Sudanese Mint Company site, cobalt, nickel, copper, and zinc, measured the highest values, whilst calcium, iron, chromium, and lead, displayed relatively high values with respect to their concentrations in the control site. The average concentrations of the elements under study in the indoor and outdoor aerosols of Sudanese Mint Company do not correlate to each other, but the outdoor measurements nearly resemble to those of the

    1999-01-01

    Radionuclides and radiopharmaceuticals play a kay role in nuclear medicine, both in diagnostics and therapy. Incorporation of radionuclides into biomolecules, and syntheses of radiolabelled compounds of high biological selectivity are a task for radiochemists working in the multidisciplinary field of radiopharmaceutical chemistry. The most commonly used radionuclide, 99m Tc, owes this popularity to its both nearly ideal nuclear properties in respect to medical imaging, and availability from inexpensive radionuclide generators. Also numerous other radionuclides are widely used for medical imaging and therapy. Labelling of biomolecules with radioiodine and various positron emitters is getting increasingly important. This review describes some chemical and radiochemical problems we meet while synthesizing and using 99m Tc-radiopharmaceuticals and radioiodine-labelled biomolecules. Also represented are the recent developments in the design and use of the second generation radiopharmaceuticals based on bifunctional radiochelates. Several principal routes of fast chemical synthesis concerning incorporation of short-lived positron emitters into biomolecules are outlined as well. The search for chemical structures of high biological selectivity, which would be activated by slow neutrons, is related to the method of Neutron Capture Therapy, an interesting option in nuclear medicine.

    This paper systematically studies relevant literatures at home and abroad in recent years. China National Knowledge Internet (CNKI) was used to collect the literatures for acute pharyngitis treated with traditional Chinese medicine from January 1, 2006, to December 31, 2016, and the bibliometric method was employed for statistical analysis. A total of 493 papers were preliminarily selected. According to the inclusion criteria and exclusion criteria, 182 eligible articles were selected. According to the evaluation and analysis of the literatures, the Guidelines for Clinical Research of New Drugs is currently used as the common standards for the diagnosis and treatment of acute pharyngitis; Chinese patent medicines are the main traditional Chinese medicine for treating this disease; Decoctions for treatment of this disease include Lonicerae Japonicae Flos, Scutellariae Radix, Platycodonis Radix, Forsythiae Fructus, Glycyrrhizae Radix et Rhizoma, Scrophdlariae Radix, Isatidis Radix, and Ophiopogonis Radix; The bloodletting puncture is the common external therapy. Traditional Chinese medicine and Western medicine have their own characteristics in the treatment of this disease. Western medicine for the treatment of acute pharyngitis are mainly antiviral, antibiotic and glucocorticoid drugs, whose disadvantages are toxicity, side effects, drug resistance and double infections. Traditional Chinese medicine doctors have rich experiences in the treatment of the disease, which is characterized by treatment determination based on syndrome differentiation, safe and reliable medication, significant curative effect, low drug resistance, and wide varieties of traditional Chinese medicine forms, convenient portability and taking, low price, and low toxic and side effects. It is an arduous and significant task to explore traditional Chinese medicine, and study and develop new-type effective drugs. Copyright© by the Chinese Pharmaceutical Association.

    Malignant tumor is one of the main causes for death in the world at present as well as a major disease seriously harming human health and life and restricting the social and economic development. There are many kinds of reports about traditional Chinese medicine patent prescriptions, empirical prescriptions and self-made prescriptions treating cancer, and prescription rules were often analyzed based on medication frequency. Such methods were applicable for discovering dominant experience but hard to have an innovative discovery and knowledge. In this paper, based on the traditional Chinese medicine inheritance assistance system, the software integration of mutual information improvement method, complex system entropy clustering and unsupervised entropy-level clustering data mining methods was adopted to analyze the rules of traditional Chinese medicine prescriptions for cancer. Totally 114 prescriptions were selected, the frequency of herbs in prescription was determined, and 85 core combinations and 13 new prescriptions were indentified. The traditional Chinese medicine inheritance assistance system, as a valuable traditional Chinese medicine research-supporting tool, can be used to record, manage, inquire and analyze prescription data.

    , descriptive statistics such as the means, standard deviations, and reliabilities of the scales were not equal across years. Therefore, we analyzed data separately by year, and then combined the results across years using meta-analysis. We first discuss the logic of analyzing the data for a single year, and then present the logic of combining the analyses.We expected that the residents in programs with sports medicine fellowships would show superior performance on the non-musculoskeletal sports medicine items. However, because assignment to fellowship was not random, we wanted to control for any possible differences in general family medicine knowledge that might exist between those residents who did and did not have a sports medicine fellowship at their residency program. Therefore, we treated scores on the family medicine scale as a covariate. We computed analysis of covariance (fellowship being a categorical independent variable with non-musculoskeletal sports medicine items as the dependent variable. The results allow for a statistical test of the effect of sports medicine fellowship while holding general family medicine knowledge constant. In other words, we applied a statistical control for self-selection into groups. We present results both with and without statistical control (i.e., both with and without the covariate because statistical control in the absence of random assignment to treatment, results in a very conservative test of the treatment effect when the treatment and covariate are correlated.To combine the studies, we used the method recommended by Hedges and colleagues (Hedges and Olkin, 1985; Hedges and Vevea, 1998. For each year, we first transformed the raw data to standardized scores by subtracting the variable's mean and dividing by the variable's standard deviation, so that all transformed variables had a mean of zero and a standard deviation of one. We then computed the analysis of covariance for each year and found the standardized regression weight

    1989-01-01

    The practice of occupational medicine has been portrayed as being fraught with ethical conflict and yet this problem has received little systematic study. A question and case study survey of a randomly selected cohort of members of the American Occupational Medical Association has been performed to examine the extent and nature of this problem in occupational medicine practice in the United States. The results indicate a strong reliance on traditional medical role models in responding to ethical conflict but with significant underlying tension between more deontological physician-patient approaches and more teleological public health approaches. These results have significant implications for the synthesis of bioethical theories based on a perceived complementarity of ethical reality, as well as suggesting important improvements in future occupational medicine training.

    Malignacies are still a major public concern worldwide and despite the intensive search for new chemotherapeutic agents, treatment still remains a challenging issue. This work was designed to assess the cytotoxicity of six selected Cameroonian medicinal plants, including Nauclea pobeguinii and its constituents 3-acetoxy-11-oxo-urs-12-ene (1), p-coumaric acid (2), citric acid trimethyl ester (3), resveratrol (4), resveratrol β- D -glucopyranoside (5) and strictosamide (6), against 8 drug-sensitive and multidrug-resistant (MDR) cancer cell lines. The resazurin reduction assay was used to evaluate the cytotoxicity of the crude extracts and compounds, whilst column chromatography was used to isolate the constituents of Nauclea pobeguinii. Structural characterization of isolated compounds was performed using nuclear magnetic resonance (NMR) spectroscopic data. Preliminary experiments on leukemia CCRF-CEM cells at 40 μg/mL showed that the leaves and bark extracts from Tragia benthamii, Canarium schweinfurthii, Myrianthus arboreus, Dischistocalyx grandifolius and Fagara macrophylla induced more than 50 % growth of this cell line contrary to the leaves and bark extracts of N. pobeguinii. IC50 values below or around 30 μg/mL were obtained with leaves and bark extracts of N. pobeguinii towards two and five, respectively, of the 8 tested cancer cell lines. The lowest IC50 value was obtained with the bark extract of N. pobeguinii against HCT116 (p53 (-/-) ) colon cancer cells (8.70 μg/mL). Compounds 4 and 6 displayed selective activity on leukemia and carcinoma cells, whilst 1-3 were not active. IC50 values below 100 μM were recorded with compound 5 on all 9 tested cancer cell lines as well as with 4 against 7 out of 8 and 6 against 2 out of 8 cell lines. Collateral sensitivity was observed in CEM/ADR5000 leukemia cells, MDA-MB-231-BCRP breast adenocarcinoma cells (0.53-fold), HCT116 (p53 (+/+) ) cells, human U87MG.ΔEGFR glioblastome multiforme cells to the methanolic

    The clinical therapeutics of traditional Chinese medicine (TCM) constitutes a complicated process which involves theory, diagnosis, and formula prescription with specific herbal dosage. Zhang Zhong-Jing's classic work, Treatise on Febrile and Miscellaneous Diseases, has been influencing TCM practice for almost 2000 years. However, during this extended period of time in Chinese history, the Chinese weight measurement system experienced noticeable changes. This change in the weight measurement system inevitably, and perhaps even negatively, affected TCM herbal dosage determination and treatment outcome. Thus, in modern society, a full understanding of the accuracy of herbal dose selection has a critical importance in the TCM daily practice of delivering the best treatment to the patients suffering from different illnesses. In the 973 Project of the Chinese National Basic Research Program, expert consensus on classic TCM formula dose conversion has been reached based on extensive literature review and discussion on the dose-effect relationship of classic TCM formulas. One "liang" in classic TCM formulas is equivalent to 13.8 g. However, based on many TCM basic and clinical studies of variable herbal formula prescriptions and herbal drug preparations, the rule of one liang equals 13.8 g should be adjusted according to different disease conditions. Recommended by the committee on TCM formula dose-effect relationship of the China Association of Chinese Medicine and the World Federation of Chinese Medicine Societies, the following expert consensus has been reached: (i) One liang converts to 6-9 g for the severely and critically ill patients. (ii) One liang converts to 3-6 g for the patients suffering from chronic diseases. (iii) One liang converts to 1-3 g in preventive medicine. The above conversions should be used as a future TCM practice guideline. Using this recommended guideline should enhance the effectiveness of daily TCM practice.

    Complementary medicines have associated risks which include toxic heavy metal(loid) and pesticide contamination. The objective of this study was to examine the speciation and bioavailability of lead (Pb) in selected complementary medicines. Six herbal and six ayurvedic medicines were analysed for: (i) total heavy metal(loid) contents including arsenic (As), cadmium (Cd), Pb and mercury (Hg); (ii) speciation of Pb using sequential fractionation and extended x-ray absorption fine structure (EXAFS) techniques; and (iii) bioavailability of Pb using a physiologically-based in vitro extraction test (PBET). The daily intake of Pb through the uptake of these medicines was compared with the safety guidelines for Pb. The results indicated that generally ayurvedic medicines contained higher levels of heavy metal(loid)s than herbal medicines with the amount of Pb much higher than the other metal(loid)s. Sequential fractionation indicated that while organic-bound Pb species dominated the herbal medicines, inorganic-bound Pb species dominated the ayurvedic medicines. EXAFS data indicated the presence of various Pb species in ayurvedic medicines. This implies that Pb is derived from plant uptake and inorganic mineral input in herbal and ayurvedic medicines, respectively. Bioavailability of Pb was higher in ayurvedic than herbal medicines, indicating that Pb added as a mineral therapeutic input is more bioavailable than that derived from plant uptake. There was a positive relationship between soluble Pb fraction and bioavailability indicating that solubility is an important factor controlling bioavailability. The daily intake values for Pb as estimated by total and bioavailable metal(loid) contents are likely to exceed the safe threshold level in certain ayurvedic medicines. This research demonstrated that Pb toxicity is likely to result from the regular intake of these medicines which requires further investigation. - Highlights: • Pb species in complementary medicines was

    To determine vending strategies and marketing themes employed by itinerant bus vendors, and assess the accuracy and completeness of information provided on medicines being sold in an urban setting in Nigeria. Cross-sectional study and content analysis of itinerant vending of medicines inside buses recorded with a mobile telephone on purposively selected routes in a mega city with an estimated 18 million residents in southwestern Nigeria over a 2-month period. Two coders independently assessed 192 vending episodes by 56 vendors for 147 OTC and prescription medicines. Inter-rater reliability (Gwet AC1 =0.924; p<0.0001). Fourteen thousands and four hundred potential consumers encountered 192 recorded episodes of vending of medicines inside 192 buses within the study periods. Forty-four (78•5%) of the 56 vendors were females in the 30-45 years age bracket, were mostly (75%) attired in the local 'Iro and Buba' Ankara fabric and showed laminated identity cards (97.5%) issued by the local association for 'marketers' of medicines inside buses, markets, and motor parks. Of the 14400 consumers encountered inside buses during the study period, between 6.7% and 48.3% purchased the medicines promoted. Prayers against death from road traffic accidents and diseases of physical and / or meta-physical origins were the most frequently used (76•8%) ice-breaking opening statement / strategy to gain consumers' attention. Hematinics, multi-vitamins, simple analgesic, NSAIDs and corticosteroids were the most frequently vended medicines. Consumers' enquiries were related to dosing for children (51.8%), elderly (28.6%), and pregnancy (52.7%); and contra-indications during pregnancy (8.9%). Factual medicines information such as dose, frequency, potential side effects and contra-indications were not provided in majority of vending episodes. Itinerant vending of medicines and the use of misleading and melodramatic themes to secure high consumer patronage appear considerable in Nigeria

    We describe a solid-phase extraction adsorbent based on molecularly imprinted polymers (MIPs), prepared with use of a mimic template. The MIPs were used for the selective extraction and determination of three chlorogenic acids as combined quality markers for Lonicera japonica and Lianhua qingwen granules. The morphologies and surface groups of the MIPs were assessed by scanning electron microscopy, Brunauer-Emmett-Teller surface area analysis, and Fourier transform infrared spectroscopy. The adsorption isotherms, kinetics, and selectivity of the MIPs were systematically compared with those of non-molecularly imprinted polymers. The MIPs showed high selectivity toward three structurally similar chlorogenic acids (chlorogenic acid, cryptochlorogenic acid, and neochlorogenic acid). A procedure using molecularly imprinted solid-phase extraction coupled with high-performance liquid chromatography was established for the determination of three chlorogenic acids from Lonicera japonica and Lianhua qingwen granules. The recoveries of the chlorogenic acids ranged from 93.1% to 101.4%. The limits of detection and limits of quantification for the three chlorogenic acids were 0.003 mg g -1 and 0.01 mg g -1 , respectively. The newly developed method is thus a promising technique for the enrichment and determination of chlorogenic acids from herbal medicines. Graphical Abstract Mimic molecularly imprinted polymers for the selective extraction of chlorogenic acids.

    Alkaloids, polyphenols, cyanogenic glycosides and saponins are among the main chemical compounds synthesized by plants but not considered essential for their basic metabolism. These compounds have different functions in plants, and have been recognized with medicinal and pharmacological properties. In this research, concentrations of the mentioned secondary metabolites were determined in the medicinal plants Artemisia absinthium, Cnidoscolus aconitifolius, Parthenium hysterophorus, Piper carpunya and Taraxacum officinale, from Ecuador, and related with cytotoxic effects against Artemia salina. Alcoholic and aqueous extracts from leaves of these selected plants were prepared at different concentrations. To assess cytotoxicity of these extracts, different bioassays with A. salina were undertaken, and the mortality rates and LC50 were obtained. Besides, concentrations of alkaloids, cyanogenic glycosides, phenols, tannins and saponins were determined by spectrophotometric methods; this constituted the first report of quantification of secondary metabolites in the selected plants from Ecuador. T. officinale had the highest concentration of total phenols (22.30 ± 0.23 mg/g) and tannins (11.70 ± 0.10 mg/g), C. aconitifolius of cyanogenic glycosides (5.02 ± 0.37 µg/g) and P. hysterophorus of saponins (6.12 ± 0.02 mg/g). Tannins values obtained were not adverse to their consumption. Alcoholic and aqueous extracts of selected plants had hemolytic activity depending on the concentration of saponins. Although the values of cyanogenic glycosides were permissible, it was necessary to monitor the presence of this metabolite in plants to minimize health problems. LC50 values ranged from extremely toxic (3.37 µg/mL) to highly toxic (274.34 μg/mL), in P. carpunya and T. officinale, respectively. From correlation analysis, it was observed that increase values of alkaloids concentrations had highly significant (pplants cytotoxicity decreased significantly (pplant extracts

    Thyroid hormone synthesis requires the presence of iodide. The sodium iodide symporter (NIS) is a glycoprotein which mediates the active uptake of iodide from the blood stream into the thyroid grand. NIS defects due to SLC5A5 gene mutations are known to cause congenital hypothyroidism (CH). The proposita is a 28-year-old female whose origin is the North Sudan where neonatal screening for CH is not available. She presented with severe constipation and a goiter at the age of 40 days. Laboratory testing confirmed CH and she was started on levothyroxine (L-T4). Presumably due to the delayed treatment the patient developed mental retardation. Her younger sister presented with a goiter, tongue protrusion and umbilical hernia and the youngest brother was also diagnosed with CH based on the TSH >100 µIU/mL at the age of 22 days and 8 days, respectively. Two siblings were treated with L-T4 and had normal development. Their consanguineous parents had no history of thyroid disorders. We performed whole exome sequencing (WES) on the proposita. WES identified a novel homozygous missense mutation in the SLC5A5 gene: c.1042T>G, p.Tyr348Asp, which was subsequently confirmed by Sanger sequencing. All affected children were homozygous for the same mutation and their unaffected mother was heterozygous. The NIS protein is composed of 13 transmembrane segments (TMS), an extracellular amino-terminus and an intracellular carboxyl terminus. The mutation is located in the TMS IX which has the most β-OH group-containing amino acids (serine and threonine) which is implicated in Na+ binding and translocation. In conclusion, a novel homozygous missense mutation in the SLC5A5 gene was identified in the Sudanese family with CH. The mutation is located in the TMS IX of the NIS protein which is essential for NIS function. Low iodine intake in Sudan is considered to affect severity of hypothyroidism in the patients.

    2009-02-01

    The potential for both positive and negative effects arising from direct-to-consumer advertising of prescription medicines challenges health policymakers to develop regulatory schemes which selectively capture the positive aspects of the practice. Australia has dealt with this quandary by banning the practice, while New Zealand and the United States permit it. However, in recent times pharmaceutical companies have been increasingly successful in introducing promotional materials into the Australian market. This article demonstrates that the Australian ban is consistent with striving for the major policy goal of quality use of medicines, thus providing the basis for arguing that solutions to strengthen the ban against the identified threats ought to be implemented. Quality use of medicines can be most effectively achieved via the combined effect of the strengthened ban and the mimicking of the limited positive aspects of direct-to-consumer advertising by government provision of non-promotional information to consumers.

    Benchmarking is as a structured continuous collaborative process in which comparisons for selected indicators are used to identify factors that, when implemented, will improve transfusion practices. This study aimed to identify transfusion medicine studies reporting on benchmarking, summarize the benchmarking approaches used, and identify important considerations to move the concept of benchmarking forward in the field of transfusion medicine. A systematic review of published literature was performed to identify transfusion medicine-related studies that compared at least 2 separate institutions or regions with the intention of benchmarking focusing on 4 areas: blood utilization, safety, operational aspects, and blood donation. Forty-five studies were included: blood utilization (n = 35), safety (n = 5), operational aspects of transfusion medicine (n = 5), and blood donation (n = 0). Based on predefined criteria, 7 publications were classified as benchmarking, 2 as trending, and 36 as single-event studies. Three models of benchmarking are described: (1) a regional benchmarking program that collects and links relevant data from existing electronic sources, (2) a sentinel site model where data from a limited number of sites are collected, and (3) an institutional-initiated model where a site identifies indicators of interest and approaches other institutions. Benchmarking approaches are needed in the field of transfusion medicine. Major challenges include defining best practices and developing cost-effective methods of data collection. For those interested in initiating a benchmarking program, the sentinel site model may be most effective and sustainable as a starting point, although the regional model would be the ideal goal.

    Full Text Available Objective: This study aimed to produce current data regarding behavioural aspects of non-prescription (over-the-counter medicine purchases, in light of changes in the pharmaceutical market and increasing provision of professional services in pharmacies.Methods: Data were collected in 15 community pharmacies in South-East Queensland, Australia, over 540 hours in five days in August, 2006. The method, previously validated, involved documentation of both observational and interview data. Fifteen trained researchers were stationed in a selected pharmacy each to unobtrusively observe all eligible sales of non-prescription medicines, and, where possible, interview the purchasers post-sale. Non-response was supplemented by observational data and recall by the salesperson. The data included details of the purchase and purchasing behaviour, while new questions addressed issues of topical importance, including customers’ privacy concerns. A selection of the analyses is reported here.Results: In total, 3470 purchases were documented (135-479 per pharmacy, with customers of 67.5% of purchases (74.7% excluding an outlier pharmacy participating in the survey. Customers averaged 1.2 non-prescription medicines per transaction. Two-thirds (67.2% of customers were female, and 38.8% of the customers were aged 31-45 years. Analgesics and respiratory medicines accounted for two-thirds of the sales data (33.4% and 32.4%, respectively. Intended-brand purchases comprised 71% of purchases (2004/2824; in-store substitution then occurred in 8.8% of these cases, mainly following recommendations by pharmacy staff. Medicines intended for self-use comprised 62.9% of purchases (1752/2785. First-time purchases (30.8%, 799/2594 were more commonly influenced by pharmacy staff than by advertising.Conclusions: This study used validated methods adapted to a changing marketplace, thus providing data that both confirm and add to knowledge surrounding medicine purchases.

    This work was conducted to evaluate the tannin content and its effect on ruminant's digestibility in 26 Sudanese sorghum varieties. Samples were brought from Agricultural Research Corporation, Wad Medani (ARC), hand cleaned and preserved in dark in plastic containers. Tannins content was measured by using vanillin-HCl method (Price et al, 1979) and in vitro digestibility was conducted to evaluate the dry meter digestibility and organic matter digestibility according to (Tilley and Terry, 1963). Results have shown that condensed tannins (vanillin-HCl) ranged between 0.39 g/kg and 23.08 g/kg, Tabat recorded the lowest value when Wad akar red recorded the highest value. An in vitro dry matter digestibility (INVDMD) and organic matter digestibility (OMD) trial were performed. There was a negative correlation (P<0.05) between organic matter and condensed tannins especially those contained high level of condensed tannins. The organic matter digestibility ranged between 680.11 g/kg in arfa gadamak commercial to 828.85 g/kg in dar baladi. The results have shown that the addition of polyethylene glycol (PEG) to in vitro incubated samples increased the gas produced in wad akar red in 24 hours by 29% compared to the control sample without (PEG). Higher significant correlation (P<0.001) between the clorox bleaching test and condensed tannins (vanillin-HCl) in samples was found. It is concluded that condensed tannins in sorghum are beneficial to ruminant when they are introduced in complete diets to avoid the inhibitory effects of condensed tannins in sorghum. Adding (PEG) to the ruminant diets which contain high levels of condensed tannins improved digestibility subsequently animal performance.(Author)

  17. Computer applications in nuclear medicine

    1987-01-01

    Digital computers were introduced to nuclear medicine research as an imaging modality in the mid-1960s. Widespread use of imaging computers (scintigraphic computers) was not seen in nuclear medicine clinics until the mid-1970s. For the user, the ability to acquire scintigraphic images into the computer for quantitative purposes, with accurate selection of regions of interest (ROIs), promised almost endless computational capabilities. Investigators quickly developed many new methods for quantitating the distribution patterns of radiopharmaceuticals within the body both spatially and temporally. The computer was used to acquire data on practically every organ that could be imaged by means of gamma cameras or rectilinear scanners. Methods of image processing borrowed from other disciplines were applied to scintigraphic computer images in an attempt to improve image quality. Image processing in nuclear medicine has evolved into a relatively extensive set of tasks that can be called on by the user to provide additional clinical information rather than to improve image quality. Digital computers are utilized in nuclear medicine departments for nonimaging applications also, Patient scheduling, archiving, radiopharmaceutical inventory, radioimmunoassay (RIA), and health physics are just a few of the areas in which the digital computer has proven helpful. The computer is useful in any area in which a large quantity of data needs to be accurately managed, especially over a long period of time

    To provide an opportunity for fourth-year students at the University of Wisconsin Medical School in Madison to immerse in urban community medicine during a 34-week program. This experience enhances the integrity of the fourth year as well as merges medicine and public health perspectives in medical education as called for by the Medicine and Public Health Initiative. A limited number of fourth-year Wisconsin medical students have the opportunity to select a one-year, continuity-based preceptorship at the Milwaukee clinical campus with a focus in one of three domains: family medicine, internal medicine, or women's health. Students participate in the following clinical activities: a one-year, integrated preceptorship (one to three half days per week in a primary preceptor's office), medicine subinternship, senior surgery clerkship, selectives (16-20 weeks of clerkships relevant to preceptorship focus area), and one month of out-of-city electives. Complementing this community-based clinical experience is the opportunity to develop an increased appreciation for urban community health issues and resources by participating in a required urban community medicine clerkship and a mentored student scholarly project focusing on an aspect of urban community medicine and population health. All students begin the year in July with a four-week urban community medicine clerkship, which is based on the St. Luke's family practice residency's community medicine rotation and arranged by residency faculty. They conduct a "windshield survey" of a Milwaukee neighborhood, observing health hazards and identifying assets, and then present these observations to others in the clerkship. During this first month, students are introduced to the work of a variety of social service agencies, the Milwaukee City Health Department, and the Aurora Health Care/UW community clinics, which serve the state's most diverse zip codes. They meet with providers and researchers who share their expertise in

    Package inserts that accompany medicines are a common source of information aimed at patients and should match patient abilities in terms of readability. Our objective was to determine the degree of readability of the package inserts for biological medicinal products commercially available in 2007 and compare them with the readability of the same package inserts in 2010. A total of 33 package inserts were selected and classified into five groups according to the type of medicine: monoclonal antibody-based products, cytokines, therapeutic enzymes, recombinant blood factors and other blood-related products, and recombinant hormones. The package inserts were downloaded from the European Medicines Agency website in 2007 and 2010. Readability was evaluated for the entire text of five of the six sections of the package inserts and for the 'Annex' when there was one. Three readability formulas were used: SMOG (Simple Measure of Gobbledygook) grade, Flesh-Kincaid grade level, and Szigriszt's perspicuity index. No significant differences were found between the readability results for the 2007 package inserts and those from 2010 according to any of the three readability indices studied (p>0.05). However, there were significant differences (preadability scores of the sections of the package inserts in both 2007 and 2010. The readability of the package inserts was above the recommended sixth grade reading level (ages 11-12) and may lead to difficulties of understanding for people with limited literacy. All the sections should be easy to read and, therefore, the readability of the medicine package inserts studied should be improved.

    The Delhi State Drug Policy was adopted in 1994 following which the first Essential Medicines List (EML) was developed in 1996. The Delhi State Essential Medicines Formulary was brought out in 1997. A need was felt to revise the formulary to match with the EML as the EML is renewed every 2 years. A survey was undertaken to elicit the opinions of the doctors practicing in the state on the usefulness of the formulary before revising and printing the updated version. The survey covered dispensaries, 10-20 bedded hospitals, 100-bedded hospitals and two tertiary care hospitals. Discussions were focused on questionnaires on attitudes toward adopting Essential Medicines Formulary using a 10-point scale. Of the 200 doctors approached, only 90 doctors completed the questionnaire. Sixty-nine respondents (76.6%) had received the copy of the formulary. Most practitioners welcomed the formulary and were satisfied with the coverage and selection of the medicines. Most respondents (76.9%) agreed that a well-developed formulary would improve the quality of the public health care system, although they had reservations about the authority, relevance and effect on professional autonomy. About 74% of the respondents used the formulary in clinical practice as a source of medicine information, which makes its regular revision necessary.

    Leishmaniasis is caused by protozoan parasites belonging to the genus Leishmania. Cutaneous leishmaniasis is the most common form of leishmaniasis in Iran. As there is not any vaccine for leishmaniasis, treatment is important to prevent the spreading of parasites. There is, therefore, a need to develop newer drugs from different sources. The aim of this study was to assess anti-leishmanial activity of the ethanolic extracts of 17 different medicinal plants against Leishmania major promastigotes and macrophage cell line J774. The selection of the hereby studied 17 plants was based on the existing information on their local ethnobotanic history. Plants were dried, powdered, and macerated in a hydroalcoholic solution. Resulting extracts have been assessed for in vitro anti-leishmanial and brine shrimp toxicity activities. Four plants, Caesalpinia gilliesii, Satureia hortensis, Carum copticum heirm, and Thymus migricus, displayed high anti-leishmanial activity (IC50, 9.76 ± 1.27, 15.625 ± 3.76, 15.625 ± 5.46, and 31.25 ± 15.44 μM, respectively) and were toxic against the J774 macrophage cell line at higher concentrations than those needed to inhibit the parasite cell growth (IC50, 45.13 ± 3.17, 100.44 ± 17.48, 43.76 ± 0.78, and 39.67 ± 3.29 μM, respectively). Glucantime as positive control inhibited the growth of L. major promastigotes with IC50 = 254 μg/ml on promastigotes (1 × 10(6)/100 μ/well) of a log phase culture, without affecting the growth of J774 macrophages. These data revealed that C. gilliesii, S. hortensis, C. copticum heirm, and T. migricus extracts contain active compounds, which could serve as alternative agents in the control of cutaneous leishmaniasis. The activity of these herbs against L. major promastigotes and macrophage cell line J774 was reported for the first time in our study.

    The current study was designed to document medicinal plant species that are traditionally used to treat tuberculosis (TB) by Ghanaian communities. The medicinal plants used against TB or its signs and symptoms were selected using library and online published data searches. A guided questionnaire interview was also conducted with a botanist involved in plant collection at the Centre for Scientific Research into Plant Medicine (CSRPM) at Mampong. Data obtained were entered in Excel and summarized into means and frequencies using SPSS 12.0.1 for windows, and expressed as tables and bar graphs. A total of 15 medicinal plant species distributed between 13 genera and 13 families were documented. The following medicinal plant species were found to be used against TB in Greater Accra and Eastern parts of Ghana: Azadirachta indica A. Juss. Stem bark (Meliaceae), Hygrophila auriculata Heine, whole plant (Acanthaceae), Chenopodium ambrosioides L. leaves (Amaranthaceae), Coix lacryma-jobi L. glumes (Poaceae), Solanum torvum Sw. unripe fruits (Solanaceae), Solanum torvum Sw. leaves (Solanaceae), Bidens pilosa L. whole plant (Asteraceae), Phyllanthus fraternus G.L. Webster leaves (Phyllanthaceae), Dissotis rotundifolia (Sm.) Triana, leaves (Melastomataceae), Cymbopogon giganteus Chiov. Leaves (Poaceae), Cyperus articulatus L. roots (Cyperaceae), Allium sativum L. bulb (Amaryllidaceae), Zingiber officinale Roscoe, rhizomes (Zingiberaceae), Allium cepa L. bulbs (Amaryllidaceae), Allium cepa L. leaves (Amaryllidaceae), Aloe vera var. barbadensis aqueous extract from leaves (Xanthorrhoeaceae), Aloe vera var. barbadensis organic extract from leaves (Xanthorrhoeaceae), Cocos nucifera Linn, water (Arecaceae) and Cocos nucifera Linn. Husk (Arecaceae). The collected plant species could be a source of a new class of drugs against TB.

    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.

    Little comparative evidence is available on utilisation of cancer medicines in different countries and its determinants. The aim of this study was to develop a statistical model to test the correlation between utilisation and possible determinants in selected European countries. A sample of 31 medicines for cancer treatment that obtained EU-wide marketing authorisation between 2000 and 2012 was selected. Annual data on medicines' utilisation covering the in- and out-patient public sectors were obtained from national authorities between 2008 and 2013. Possible determinants of utilisation were extracted from HTA reports and complemented by contacts with key informants. A longitudinal mixed effect model was fitted to test possible determinants of medicines utilisation in Belgium, Scotland and Sweden. In the all-country model, the number of indications reimbursed positively correlated with increased consumption of medicines [one indication 2.6, 95% CI (1.8-3.6); two indications 2.4, 95% CI (1.4-4.3); three indications 4.9, 95% CI (2.2-10.9); all P marketing authorisation [1.2, 95% CI (1.02-1.4); p marketing authorisation. Prices had a negative effect on consumption in Belgium and Sweden. The positive impact of financial MEAs in Scotland suggests that the latter may remove the regressive effect of list prices on consumption.

    Precision medicine allows tailoring of preventive or therapeutic interventions to avoid the expense and toxicity of futile treatment given to those who will not respond. Lung cancer is a heterogeneous disease functionally and morphologically. PET is a sensitive molecular imaging technique with a major role in the precision medicine algorithm of patients with lung cancer. It contributes to the precision medicine of lung neoplasia by interrogating tumor heterogeneity throughout the body. It provides anatomofunctional insight during diagnosis, staging, and restaging of the disease. It is a biomarker of tumoral heterogeneity that helps direct selection of the most appropriate treatment, the prediction of early response to cytotoxic and cytostatic therapies, and is a prognostic biomarker in patients with lung cancer.

    2011-01-01

    Nanoparticles and low-temperature plasmas have been developed, independently and often along different routes, to tackle the same set of challenges in biomedicine. There are intriguing similarities and contrasts in their interactions with cells and living tissues, and these are reflected directly in the characteristics and scope of their intended therapeutic solutions, in particular their chemical reactivity, selectivity against pathogens and cancer cells, safety to healthy cells and tissues and targeted delivery to diseased tissues. Time has come to ask the inevitable question of possible plasma-nanoparticle synergy and the related benefits to the development of effective, selective and safe therapies for modern medicine. This perspective paper offers a detailed review of the strengths and weakenesses of nanomedicine and plasma medicine as a stand-alone technology, and then provides a critical analysis of some of the major opportunities enabled by synergizing nanotechnology and plasma technology. It is shown that the plasma-nanoparticle synergy is best captured through plasma nanotechnology and its benefits for medicine are highly promising.

    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.

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.

    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.

    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.

    2009-10-01

    There are a large number of fuzzy concepts and fuzzy phenomena in traditional Chinese medicine, which have led to great difficulties for study of traditional Chinese medicine. In this paper, the mathematical methods are used to quantify fuzzy concepts of drugs and prescription. We put forward the process of innovation formulations and selection method in Chinese medicine based on the Possibility Construction Space Theory (PCST) and fuzzy pattern recognition. Experimental results show that the method of selecting medicines from a number of characteristics of traditional Chinese medicine is consistent with the basic theory of traditional Chinese medicine. The results also reflect the integrated effects of the innovation compound. Through the use of the innovation formulations system, we expect to provide software tools for developing new traditional Chinese medicine and to inspire traditional Chinese medicine researchers to develop novel drugs.

    Bedside point-of-care ultrasound (POCUS) is increasingly used to assess medical patients. At present, no consensus exists for what POCUS curriculum is appropriate for internal medicine residency training programs. This document details the consensus-based recommendations by the Canadian Internal Medicine Ultrasound (CIMUS) group, comprising 39 members, representing 14 institutions across Canada. Guiding principles for selecting curricular content were determined a priori. Consensus was defined as agreement by at least 80% of the members on POCUS applications deemed appropriate for teaching and assessment of trainees in the core (internal medicine postgraduate years [PGY] 1-3) and expanded (general internal medicine PGY 4-5) training programs. We recommend four POCUS applications for the core PGY 1-3 curriculum (inferior vena cava, lung B lines, pleural effusion, and abdominal free fluid) and three ultrasound-guided procedures (central venous catheterization, thoracentesis, and paracentesis). For the expanded PGY 4-5 curriculum, we recommend an additional seven applications (internal jugular vein, lung consolidation, pneumothorax, knee effusion, gross left ventricular systolic function, pericardial effusion, and right ventricular strain) and four ultrasound-guided procedures (knee arthrocentesis, arterial line insertion, arterial blood gas sampling, and peripheral venous catheterization). These recommendations will provide a framework for training programs at a national level.

    Thai Traditional Medicine (TTM) is available in many modern hospitals in Thailand. However, there have been difficulties in integrating TTM, particularly the practices of the use of herbal medicines, into modern healthcare services. Kabchoeng Hospital is one hospital that has been able to overcome these difficulties. Thus, this study aimed to document the successful utilization of herbal medicine at Kabchoeng Hospital. The documentation focused on both the knowledge of medicinal plants and the success factors that facilitated the utilization of herbal medicine in the context of a modern hospital in Thailand. Kabchoeng Hospital was intentionally selected for this case study. Participatory observation was used for the data collection. There were six groups of key informants: three applied Thai Traditional Medicine practitioners (ATTMPs), a pharmacist, two physicians, two folk healers, the head of an herbal cultivation and collection group, and 190 patients. The plant specimens were collected and identified based on the botanical literature and a comparison with authentic specimens; these identifications were assisted by microscopic and thin layer chromatography (TLC) techniques. Eighty-nine medicinal plants were used for the herbal preparations. The ATTMPs used these plants to prepare 29 standard herbal preparations and occasional extemporaneous preparations. Moreover, in this hospital, seven herbal preparations were purchased from herbal medicine manufacturers. In total, 36 preparations were used for 10 groups of symptoms, such as the treatment of respiratory system disorders, musculo-skeletal system disorders, and digestive system disorders. Four success factors that facilitated the utilization of herbal medicine at Kabchoeng Hospital were determined. These factors included a proper understanding of the uses of herbal medicines, the successful integration of the modern and TTM healthcare teams, the support of an herbal cultivation and collection group, and the

    To determine the prevalence, among adolescents, of medicine use for headache, stomachache, difficulties in getting to sleep and nervousness, and to analyse its association with common lifestyles. Data were taken from the Health Behaviour in School-aged Children (HBSC), a transnational study coordinated by the WHO. The data are collected through a self-administered questionnaire for investigating health and health behaviours. 80 middle schools and 84 high schools were randomly selected from all Italian public and private schools. The questionnaire was filled out by a representative sample of 2667 (50.1% males) 13- and 15- year-old Italian students. Medicine use for headache, stomachache, difficulties in getting to sleep and nervousness, socio-economic status, physical fitness, breakfast, smoking and drunkenness. Females are more likely than boys to use medicines for headache (41.2% vs 30%) and stomachache (29%vs 16.2%), but there are no gender differences regarding medicines for difficulties in getting to sleep and nervousness, which are used less frequently. The prevalence of the use of medicines does not increase with age. The related behaviours are: for headache, breakfast, smoking and drunkenness; for stomachache, physical fitness, breakfast and smoking; for difficulties in getting to sleep and nervousness, drunkenness. The extensive use of medicines in adolescence and its association with some lifestyles suggest the importance to develop education programmes for adolescents.

    Plant phenolics and flavonoids have a powerful biological activity, which outlines the necessity of their determination. The phenolics and flavonoids content of 20 medicinal plants were determined in the present investigation. The phenolic content was determined by using Folin-Ciocalteu assay. The total flavonoids were measured spectrophotometrically by using the aluminium chloride colorimetric assay. The results showed that the family Mimosaceae is the richest source of phenolics, (Acacia nilotica: 80.63 mg gallic acid equivalents, Acacia catechu 78.12 mg gallic acid equivalents, Albizia lebbeck 66.23 mg gallic acid equivalents). The highest total flavonoid content was revealed in Senna tora which belongs to the family Caesalpiniaceae. The present study also shows the ratio of flavonoids to the phenolics in each sample for their specificity.

    Objective: The Delhi State Drug Policy was adopted in 1994 following which the first Essential Medicines List (EML) was developed in 1996. The Delhi State Essential Medicines Formulary was brought out in 1997. A need was felt to revise the formulary to match with the EML as the EML is renewed every 2 years. Materials and Methods: A survey was undertaken to elicit the opinions of the doctors practicing in the state on the usefulness of the formulary before revising and printing the updated version. The survey covered dispensaries, 10–20 bedded hospitals, 100-bedded hospitals and two tertiary care hospitals. Discussions were focused on questionnaires on attitudes toward adopting Essential Medicines Formulary using a 10-point scale. Results: Of the 200 doctors approached, only 90 doctors completed the questionnaire. Sixty-nine respondents (76.6%) had received the copy of the formulary. Most practitioners welcomed the formulary and were satisfied with the coverage and selection of the medicines. Most respondents (76.9%) agreed that a well-developed formulary would improve the quality of the public health care system, although they had reservations about the authority, relevance and effect on professional autonomy. Conclusion: About 74% of the respondents used the formulary in clinical practice as a source of medicine information, which makes its regular revision necessary. PMID:20871765

    In recent years a number of intergovernmental initiatives have been activated in order to enhance the capacity of countries to improve access to essential medicines, particularly for mental disorders. In May 2013 the 66th World Health Assembly adopted the World Health Organization (WHO) Comprehensive Mental Health Action Plan 2013-2020, which builds upon the work of WHO's Mental Health Gap Action Programme. Within this programme, evidence-based guidelines for mental disorders were developed, including recommendations on appropriate use of medicines. Subsequently, the 67th World Health Assembly adopted a resolution on access to essential medicines, which urged Member States to improve national policies for the selection of essential medicines and to promote their availability, affordability and appropriate use. Following the precedent set by these important initiatives, this article presents eleven actions for improving access and appropriate use of psychotropic medicines. A 4 × 4 framework mapping actions as a function of the four components of access - selection, availability, affordability and appropriate use - and across four different health care levels, three of which belong to the supply side and one to the demand side, was developed. The actions are: developing a medicine selection process; promoting information and education activities for staff and end-users; developing a medicine regulation process; implementing a reliable supply system; implementing a reliable quality-control system; developing a community-based system of mental health care and promoting help-seeking behaviours; developing international agreements on medicine affordability; developing pricing policies and a sustainable financing system; developing or adopting evidence-based guidelines; monitoring the use of psychotropic medicines; promoting training initiatives for staff and end-users on critical appraisal of scientific evidence and appropriate use of psychotropic medicines.

    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

    2013-12-01

    Populations of medicinal plants growing on serpentines and their respective soils were analyzed for Fe, Ni, Mn, Cr, Co, Cd, Cu, Zn, and Pb using inductively coupled plasma atomic emission spectrometry. Aqua regia extraction and 0.43 M acetic acid extraction were used for the quantification of pseudototal and bioavailable fractions, respectively, of elements in soil and nitric acid digestion for determination of total element content in plants. Screening was performed to (1) document levels of toxic metals in herbs extensively used in preparation of products and standardized extracts, (2) compare accumulation abilities of ferns and seed plants, and (3) estimate correlations between metal content in plants and their soils. The toxic element content of plants varied from site to site on a large scale. The concentrations of Fe and Ni were elevated while those of Cu, Zn, and Pb were close to average values usually found in plants. The highest concentrations for almost all elements were measured in both Teucrium species. Specific differences in metal accumulation between ferns and seed plants were not recorded. The investigated species are not hyperaccumulators but can accumulate toxic elements, in some cases exceeding permissible levels proposed by the World Health Organization and European Pharmacopoeia. The harvesting of medicinal plants from serpentines could be hazardous to humans.

    Midlevel providers (eg, nurse practitioners and physician assistants) have been integrated into orthopaedic systems of care in response to the increasing demand for musculoskeletal care. Few studies have examined patient perspectives toward midlevel providers in orthopaedic sports medicine. To identify perspectives of orthopaedic sports medicine patients regarding midlevel providers, including optimal scope of practice, reimbursement equity with physicians, and importance of the physician's midlevel provider to patients when initially selecting a physician. Cross-sectional study; Level of evidence, 3. A total of 690 consecutive new patients of 3 orthopaedic sports medicine physicians were prospectively administered an anonymous questionnaire prior to their first visit. Content included patient perspectives regarding midlevel provider importance in physician selection, optimal scope of practice, and reimbursement equity with physicians. Of the 690 consecutive patients who were administered the survey, 605 (87.7%) responded. Of these, 51.9% were men and 48.1% were women, with a mean age of 40.5 ± 15.7 years. More than half (51.2%) perceived no differences in training levels between physician assistants and nurse practitioners. A majority of patients (62.9%) reported that the physician's midlevel provider is an important consideration when choosing a new orthopaedic sports medicine physician. Patients had specific preferences regarding which services should be physician provided. Patients also reported specific preferences regarding those services that could be midlevel provided. There lacked a consensus on reimbursement equity for midlevel practitioners and physicians, despite 71.7% of patients responding that the physician provides a higher-quality consultation. As health care becomes value driven and consumer-centric, understanding patient perspectives on midlevel providers will allow orthopaedic sports medicine physicians to optimize efficiency and patient

    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

The articles published from 2002 to 2012 addressing the use of medicinal plants in dentistry were included and analyzed. The searches based on the descriptors and reading of abstracts, resulted in 155 articles. Of these, 44 were read in full and a total of 16 publications met the eligibility criteria and were selected. Laboratory studies predominated (10 and were limited to the evaluation of antimicrobial properties by means of tests for determining inhibitory, fungicidal and bactericidal concentrations. Three literature reviews and only one clinical trial with no blinding and randomization were found. It is highlighted the need for better methodological designs in the researches and greater production of clinical or in vivo studies.

    The following conclusions can be drawn: 1) Even though developments in data digitalization enable also other imaging techniques to extract functional information, it is likely that nuclear medicine will keep and possibly increase its key role for functional studies requiring quantitative data analyses. This statement is true at present and it will probably remain true for a long time to come. 2) Nuclear medicine is and will remain an important clinical tool also for morphological or morphodynamic studies in selected situations. Of course the integration of nuclear medicine studies with other diagnostic procedures is highly desirable. The highest clinical yield of multi-test diagnostic protocols will be anyway obtained by the wisest physician as sophysticated technology is no substitution for intelligent clinical judgment. 3) The development of new radiopharmaceuticals with well characterized biokinetic features allowing precise tissue characterization opens new frontiers to be exploited by nuclear medicine centers equipped with conventional technology (digital gammacameras, SPECT). 4) Positron emission tomography is the most important new development of nuclear medicine imaging. Not only PET has already shown its enormous possibilities for physiological and pathophysiological studies, but the clinical relevance of selected applications has been proved. More experience is however needed to assess systematically the whole impact of PET studies in clinical practice and to perform dependable cost/benefit studies. 5) Among all other imaging techniques NMR is the closest to nuclear medicine because of a strict ''compatibility of aptitudes, training and methodology'' (4). Accordingly future improvements of both methods will be better achieved if they could be integrated and the results compared with the same institutions

    The effectiveness of antimalarial drugs is declining at an ever accelerating rate, with consequent increase in malaria-related morbidity and mortality. The newest antiplasmodial drug from plants is needed to overcome this problem. The aim of this study was to assess antimalarial activity of the ethanolic extracts of 10 different medicinal plants from eight families against Plasmodium falciparum chloroquine-sensitive 3D7 strain. The selection of the hereby studied plants was based on the existing information on their local ethnobotanic history. Plants were dried, powdered, and macerated in a hydroalcoholic solution. Resulting extracts have been assessed for in vitro and in vivo antimalarial and brine shrimp toxicity activities. Of 10 plant species tested, four plants: Althea officinalis L. (Malvaceae), Myrtus communis Linn (Myrtaceae), Plantago major (Plantaginaceae), and Glycyrrhiza glabra L. (Papilionaceae) displayed promising antimalarial activity in vitro (50% inhibitory concentration values of 62.77, 42.18, 40.00, and 13.56 μg/mL, respectively) with no toxicity against brine shrimp larvae. The crude extracts of three active plants, G. glabra, M. communis, and A. officinalis, also significantly reduced parasitemia in vivo in female Swiss albino mice at a dose of 400 mg/kg compared to no treatment. Antiplasmodial activities of extracts of A. officinalis and M. communis are reported for the first time.

    Although there are current efforts to integrate herbal medicine (HM) into mainstream healthcare in Ghana, there is paucity of empirical evidence on the acceptability and concurrent use of HM, in the formal health facilities in Ghana. This study sought to determine client perception, disclosure and acceptability of integrating herbal medicine in mainstream healthcare in Kumasi, Ghana. A cross-sectional study was conducted from May to August, 2015. Five hundred patients presenting at the outpatient departments of Kumasi South, Suntreso and Tafo Government Hospitals in Kumasi were randomly selected. Interviews were conducted with the use of structured questionnaires. A logistic regression analysis, using backward selection, was conducted to determine the influence of socio-demographic and facility related factors on the odds of using HM at the facility. All statistical tests were two-sided and considered significant at a p-value of herbal medicines. Respondents who rated themselves wealthy had increased odds of using herbal medicines at the health facility as compared to those who rated themselves poor (OR = 4.9; 95%CI = 1.6-15.3). This study shows that integration of herbal medicine is feasible and herbal medicines may be generally accepted as a formal source of healthcare in Ghana. The results of this study might serve as a basis for improvement and upscale of the herbal medicine integration programme in Ghana.

    Over the past few decades, there has been a trend toward an increasing subspecialization in orthopaedic surgery, with orthopaedic sports medicine being one of the most competitive subspecialties. Information regarding the application and interview process for sports medicine fellowships is currently lacking. To survey orthopaedic sports medicine fellowship program directors (PDs) to better define the structure of the sports medicine fellowship interview and to highlight important factors that PDs consider in selecting fellows. Cross-sectional study. A complete list of accredited programs was obtained from the American Orthopaedic Society for Sports Medicine (AOSSM) website. An anonymous survey was distributed to fellowship PDs of all Accreditation Council for Graduate Medical Education (ACGME)-accredited orthopaedic sports medicine fellowships in the United States. The survey included 12 questions about the fellowship interview and selection process. Of the 95 orthopaedic sports medicine fellowship PDs surveyed, 38 (40%) responded. Of these, 16 (42.1%) indicated that they interview between 21 and 30 applicants per year. Eleven of the 38 fellowship programs (28.9%) have only 1 fellow per year at their respective program. Most programs (27/37, 73%) reported that between 0 and 5 faculty members interview applicants, and 29 of the 38 programs (76.3%) arrange for applicants to have ≥4 interviews during their interview day. Large group interviews are conducted at 36 of 38 (94.7%) sports medicine fellowship programs, and most programs (24/38, 63.2%) hold individual interviews that last between 5 and 15 minutes. The most important applicant criterion taken into account by PDs was the quality of the interview, with an average score of 8.68 of 10. The most significant factor taken into account by PDs when deciding how to rank applicants was the quality of the interview. Many orthopaedic sports medicine fellowship programs interview between 21 and 30 applicants per year

    The goal of precision medicine is to separate patient populations into groups to ultimately provide customized care tailored to patients. In terms of precision medicine, ~540 million people in the world have a genetic variant of the aldehyde dehydrogenase 2 (ALDH2) enzyme causing a flushing response and tachycardia after alcohol consumption. The genetic variant is identified as ALDH2*2 and originates from East Asian descendants of the Han Chinese. The variant is particularly important to consider when discussing lifestyle choices with patients in terms of risk for developing specific diseases, preventative screening, and selection of medications for treatment. Here we provide examples why patients with an ALDH2*2 variant need more individualized medical management which is becoming a more standard practice in the precision medicine era.

    The aim of this study was to estimate patient dose, the annual frequency and the number of staff and devices in the medical applications of ionizing radiation in Sudan. Survey was conducted on diagnostic radiology, nuclear medicine and radiotherapy. With respect to diagnostic radiology, only patient radiation dose was estimated. The data for diagnostic radiology was obtained from 24 peer reviewed scientific published literatures during the years ( 2006 - 2015). The collected publications included about 64 Sudanese hospitals covering different types of diagnostic exams. A values of the effective dose for pediatrics and adult patients were within the ranges of similar worldwide values published by UNSCEAR report in 2008 with exceptional to fluoroscopy hysterosalpingography for adult patients. For nuclear medicine procedures, questionnaires were distributed to five hospitals representing the whole existing NM department in Sudan at the time of of study. The estimated total annual frequency of diagnostic procedures was 0.2 per 1000 population. The estimated total annual collective and annual per caput effective dose from all NM procedures were 16.268 man Sv and 0.5 μSv, respectively. Comparing the annual per caput effective dose with UNSCEAR value our results was less than the worldwide value and greater than the value for heath care level 111-1 v countries. Questionnaires were also distributed to collect data on radiotherapy procedures performed in the two existing radioisotopes Sudanese hospitals. The prescribed dose and the number of fractions were comparable between the two hospitals. The minimum prescribed dose was 20 Gy with 5 fractions for nasopharynx (NPH) palliative and the maximum prescribed dose was 64 Gy with 32 fractions for prostate.(Author)

    Traditional interviews for residency and fellowship training programs are an important component in the selection process, but can be of variable value due to a nonstandardized approach. We redesigned the candidate interview process for our large pulmonary and critical care medicine fellowship program in the United States using a behavioral-based interview (BBI) structure. The primary goal of this approach was to standardize the assessment of candidates within noncognitive domains with the goal of selecting those with the best fit for our institution's fellowship program. Eight faculty members attended two BBI workshops. The first workshop identified our program's "best fit" criteria using the framework of the Accreditation Council for Graduate Medical Education's six core competencies and additional behaviors that fit within our programs. BBI questions were then selected from a national database and refined based on the attributes deemed most important by our faculty. In the second workshop, faculty practiced the BBI format in mock interviews with third-year fellows. The interview process was further refined based on feedback from the interviewees, and then applied with fellowship candidates for the 2014 recruitment season. The 1-year pilot of behavioral-based interviewing allowed us to achieve consensus on the traits sought for our incoming fellows and to standardize the interview process for our program using the framework of the Accreditation Council for Graduate Medical Education core competencies. Although the effects of this change on the clinical performance of our fellows have not yet been assessed, this description of our development and implementation processes may be helpful for programs seeking to redesign their applicant interviews.

    Access to free essential medicines is a critical component of universal health coverage. However availability of essential medicines is poor in India with more than two-third of the people having limited or no access. This has pushed up private out-of-pocket expenditure due to medicines. The states of Punjab and Haryana are in the process of institutionalizing drug procurement models to provide uninterrupted access to essential medicines free of cost in all public hospitals and health centres. We undertook this study to assess the availability of medicines in public sector health facilities in the 2 states. Secondly, we also ascertained the quality of storage and inventory management systems in health facilities. The present study was carried out in 80 public health facilities across 12 districts in Haryana and Punjab states. Overall, within each state 1 MC, 6 DHs, 11 CHCs and 22 PHCs were selected for the study. Drug procurement mechanisms in both the states were studied through document reviews and in-depth interviews with key stakeholders. Stock registers were reviewed to collect data on availability of a basket of essential medicines -92 at Primary Health Centre (PHC) level, 132 at Community Health Centre (CHC) level and 160 at tertiary care (District Hospital/Medical College) level. These essential medicines were selected based on the Essential Medicine List (EML) of the Department of Health (DOH). Overall availability of medicines was 45.2% and 51.1% in Punjab and Haryana respectively. Availability of anti-hypertensives was around 60% in both the states whereas for anti-diabetics it was 44% and 47% in Punjab and Haryana respectively. Atleast one drug in each of the categories including analgesic/antipyretic, anti-helminthic, anti-spasmodic, anti-emetic, anti-hypertensive and uterotonics were nearly universally available in public sector facilities. On the contrary, medicines such as thrombolytics, anti-cancer and endocrine medicines were available in less

    Information from Ayurveda meeting the analytical challenges of modern technology is an area of immense relevance. Apart from the cerebral task of bringing together two different viewpoints, the question at the pragmatic level remains 'who benefits whom'. The aim is to highlight the challenges in integration of information (Ayurvedic) and technology using test examples of Nuclear Magnetic Resonance (NMR) metabolomics and anti-HIV-1 potential of select Ayurvedic medicinal plants. The other value added objective is implications and relevance of such work for Ayurveda. Six medicinal plants (Azadirachta indica, Tinospora cordifolia, Swertia chirata, Terminalia bellerica, Zingiber officinale and Symplocos racemosa) were studied using high resolution proton NMR spectroscopy based metabolomics and also evaluated for anti-HIV-1 activity on three pseudoviruses (ZM53 M.PB12, ZM109F.PB4, RHPA 4259.7). Of the six plants, T.bellerica and Z.officinale showed minimum cell cytotoxicity and maximum anti-HIV-1 potential. T.bellerica was effective against all the three HIV-1 pseudoviruses. Untargeted NMR profiling and multivariate analyses demonstrated that the six plants, all of which had different Ayurvedic pharmacological properties, showed maximum differences in the aromatic region of the spectra. The work adds onto the list of potential plants for anti-HIV-1 drug molecules. At the same time, it has drawn attention to the different perspectives of Ayurveda and Western medicine underscoring the inherent limitations of conceptual bilinguism between the two systems, especially in the context of medicinal plants. The study has also highlighted the potential of NMR metabolomics in study of plant extracts as used in Ayurveda.

    This review article focuses on pre-clinical and clinical studies with some selected Brazilian medicinal plants in different areas of interest, conducted by research groups in Brazil and abroad. It also highlights the Brazilian market of herbal products and the efforts of Brazilian scientists to develop new phytomedicines. This review is divided into three sections. The section I describes the Brazilian large biodiversity and some attempts of Brazilian scientists to assess the pharmacological profile of most plant extracts or isolated active principles. Of note, Brazilian scientists have made a great effort to study the Brazilian biodiversity, especially among the higher plants. In fact, more than 10,000 papers were published on plants in international scientific journals between 2011 and 2013. This first part also discussed the main efforts to develop new medicines from plants, highlighting the Brazilian phytomedicines market. Despite the large Brazilian biodiversity, notably with the higher plants, which comprise over 45,000 species (20-22% of the total worldwide), and the substantial number of scientific publications on medicinal plants, only one phytomedicine is found in the top 20 market products. Indeed, this market is still only worth about 261 million American dollars. This represents less than 5% of the global Brazilian medicine market. The section II of this review focus on the use of Brazilian plant extract and/or active principles for some selected diseases, namely: central nervous systems disorders, pain, immune response and inflammation, respiratory diseases, gastrointestinal tract and metabolic diseases. Finally, section III discusses in more details some selected Brazilian medicinal plants including: Cordia verbenacea, Euphorbia tirucalli, Mandevilla velutina, Phyllanthus spp., Euterpe oleracea, Vitis labrusca, Hypericum caprifoliatum and Hypericum polyanthemum, Maytenus ilicifolia, Protium kleinii and Protium heptaphylium and Trichilia catigua.

    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.

    Interstitial lung diseases in general, and idiopathic pulmonary fibrosis in particular, are complex disorders with multiple pathogenetic pathways, various disease behaviour profiles and different responses to treatment, all facets that make personalised medicine a highly attractive concept. Personalised medicine is aimed at describing distinct disease subsets taking into account individual lifestyle, environmental exposures, genetic profiles and molecular pathways. The cornerstone of personalised medicine is the identification of biomarkers that can be used to inform diagnosis, prognosis and treatment stratification. At present, no data exist validating a personalised approach in individual diseases. However, the importance of the goal amply justifies the characterisation of genotype and pathway signatures with a view to refining prognostic evaluation and trial design, with the ultimate aim of selecting treatments according to profiles in individual patients.

    Traditional medicinal practices play a key role in health care systems in countries with developing economies. The aim of this survey was to validate the use of traditional medicine within local Nigerian communities. In this review, we examine the ethnobotanical uses of selected plant species from the Nigerian flora and attempt to correlate the activities of the isolated bioactive principles with known uses of the plant species in African traditional medicine. Thirty-three (33) plant species were identified and about 100 out of the 120 compounds identified with these plants matched with the ethnobotanical uses of the plants.

    Influenza is still a serious threat to human health with significant morbidity and mortality. The emergence of drug-resistant influenza viruses poses a great challenge to existing antiviral drugs. Traditional Chinese medicines (TCMs) may be an alternative to overcome the challenge. Here, 10 oral proprietary Chinese medicines were selected to evaluate their anti-influenza activities. These drugs exhibit potent inhibitory effects against influenza A H1N1, influenza A H3N2, and influenza B virus. Importantly, they demonstrate potent antiviral activities against drug-resistant strains. In the study of mechanisms, we found that Xiaoqinglong mixture could increase antiviral interferon production by activating p38 MAPK, JNK/SAPK pathway, and relative nuclear transcription factors. Lastly, our studies also indicate that some of these medicines show inhibitory activities against EV71 and CVB strains. In conclusion, the 10 traditional Chinese medicines, as kind of compound combination medicines, show broad-spectrum antiviral activities, possibly also including inhibitory activities against strains resistant to available antiviral drugs.

    The study aimed at assessment of the Polish occupational medicine service system after over ten years of functioning in the current shape, made by occupational nurses. The article focuses on the job satisfaction level among Polish occupational medicine nurses. The survey was performed among 600 randomly selected occupational medicine nurses, registered in the regional occupational medicine centers. A questionnaire, designed by the research team, containing several questions concerning different aspects of OMS system assessment, including a part dedicated to job satisfaction assessment, was sent to the selected occupational nurses. The response rate was 33.3% (200 questionnaires). The survey shows a relatively high satisfaction level in case of five out of eleven investigated job aspects, and a very low satisfaction level in case of two of them ("Possibility of professional promotion", "Salary"). 26% of the OMS nurses had considered going abroad to work as a nurse in the general health care system, and 17% in the OHS system. Almost 25% of them would not choose a profession of an occupational nurse once again, including 10% who would not choose a nurse job at all. There is a statistically significant correlation between the general job satisfaction and satisfaction with other aspects of nursing work. A strong correlation was observed in case of "Scope of performed tasks" and "Cooperation with employers (clients of the occupational medicine service units)". There is a statistically significant correlation of average strength between the decision concerning choosing an occupational nurse job in case of taking a decision on professional carrier once again and "General job satisfaction". Polish occupational nurses are satisfied with their job, however only 26% are fully satisfied. In their work there is place for improvement. The areas which definitely need attention and improvement are "Possibility of professional promotion" and "Salary". Improvements in cooperation

A pharmacy exit survey was conducted over a 6-month period across Malaysia. A one-stage random cluster sampling technique was employed as there was no national sampling framework available for conducting this survey. Face-to-face interviews using a validated and pre-tested questionnaire were conducted by trained data collectors. The non-prescription medicine purchasing pattern was explored and analysed descriptively. Chi-square/Fisher exact test was used to determine the association between study variables. Multinomial logistic regression analysis was used to determine the predictors of type of non-prescription medicine purchased. RESULTS: A total of 2729 pharmacy patrons agreed to participate in 60 selected pharmacy outlets. A total of 3462 non-prescription medicine were purchased during the study period with an average of 1.3 medicines per participant. Most of the non-prescription medicine purchased was meant for alimentary tract and metabolism (31.8%, followed by respiratory system (19.4% and musculoskeletal system (15.8% usage. Factors found to be associated with the choice of non-prescription medicine purchased were age group [χ2 = 170.75, (df = 57, p<0.01], locality [χ2 = 48.16, (df = 19, p<0.01], gender [χ2 = 32.93, (df = 13, p = 0.002], ethnic group [χ2 = 118.89, (df = 39, p<0.01] and type of occupation [χ2 = 222.434, (df = 117, p<0.01]. Non-prescription medicine purchased defined about 20% of the variance in the combination of predictors such as locality, gender, age, ethnicity, type of occupation and household income. CONCLUSION: The predictors for selection of non-prescription medicine were locality (urban or rural, gender, age, ethnicity, type of

    PHENOMENON: Attitudes of medical students toward family medicine as a specialty choice can provide information on the future supply of family physicians. Due to the current worldwide shortage of family physicians, these attitudes, with their subsequent effects on the state and dynamics of the healthcare system, are important to investigate. A web-based questionnaire was sent to 600 medical students, selected by a systematic random sampling technique, in 7 Egyptian medical schools. Participants were surveyed to assess their perception of the family medicine specialty as a future career and explore the impact of different factors, including undergraduate family medicine clerkships, on their attitudes toward family medicine. We had a response rate of 75.2% (n = 451). Although 90.7% of students believed in the vital role that family medicine can play in Egypt's healthcare system, only 4.7% showed an intention to choose it as a future career. Students choosing family medicine as a first-career choice were more likely to have a prior contact with family physicians as consumers. Exposure to an undergraduate family medicine curriculum was associated with increased knowledge about family medicine but not the intentions to pursue it as a career. INSIGHTS: Medical students in Egypt have a positive perception of family medicine as an important specialty but low interest in its choice as a future career.

    Thirteen plants which are traditionally used for the treatment of dysentery and diarrhoea in Myanmar were selected and tested for antibacterial activity by using agar disc diffusion technique. Polar and nonpolar solvents were employed for extraction of plants. The minimum inhibitory concentration (MIC) of the extracts with the most significant predominant activity were evaluated by plate dilution method. The plants Eugenia jambolana, Quisqualis indica, Leucaena glauca and Euphorbia splendens var. 1 were found to show significant antibacterial activity. It was also observed that extracts using nonpolar solvents did not show any antibacterial activity and extracts using polar solvents showed antibacterial activity on tested bacteria, indicating that the active chemical compound responsible for the antibacterial action must be a polar soluble compound.

    Background: Hand Eczema (HE) is a dermatological disorder with frequent relapses and multiple causes such as atopic, allergic and irritant contact dermatitis. The management is complex because of the wide range of different pathogenesis. Efficacy of some of available treatments is not well established and it can affect patients’ quality of life significantly. Methods: Reports on HE such as diagnosis, pathophysiology, pharmacological and nonpharmacological therapy that described in medieval Iranian medicine, were gathered and analyzed from selected medical and pharmaceutical textbooks of Iranian Traditional Medicine (ITM). The search of databases such as PubMed, EMBASE/Excerpta Medica, Science direct, Scopus, Google scholar, Web of science, Sid, Iran medex, Irandoc, was performed to reconfirm the efficacy of ITM remedies in conventional medicine from 1980-Jan-1 to 2015-Dec-30. Results: According to their opinion, HE is highly associated with liver function. This disorder was categorized into two main types as wet and dry ones. Most Iranian textbook explained signs of HE, as excessive skin itching, redness, burning and dryness. Treatments recommended by Iranian scientists were lifestyle modification, dietary intervention and performing the rules of prevention as well as herbal therapy and special manipulations. Conclusion: Iranian practitioners believed that, six essential principles, diet therapy and medicinal plants have high impact on treatment of HE. These remedies based on Iranian scholar’s experiences might be useful for further studies to the management of HE. PMID:27928524

    Approximately 45% of asthmatic families and 47% of non-asthmatic families had consulted an alternative-medicine practitioner at some time. The most popular form of alternative medicine was chiropractic (21.1% and 26.4%, respectively), followed by homoeopathy/naturopathy (18.8% and 12.7%, respectively), acupuncture (9.4% and 10.9%, respectively), and herbal medicine (4.7% and 6.4%, respectively), while the remainder (20.3% and 11.8% respectively) was distributed among iridology, osteopathy, hypnosis, faith healing and megavitamin therapy. More families were satisfied with orthodox medicine (87.1% and 93.6%, respectively) than with alternative medicine (84.2% and 75.1%, respectively). Crosstabulation analysis of pooled data both from asthma and from non-asthma groups showed that 76.4% were satisfied both with orthodox and with alternative medicine, and 16.4% were satisfied with orthodox, but not with alternative, medicine. In contrast, only 2.7% were dissatisfied with orthodox medicine and satisfied with alternative medicine (chi2 = 9.33; P less than 0.01). These findings do not support the view that patients who use alternative medicine are those who are disgruntled with orthodox medicine.

    Full Text Available OBJECTIVE: Sex-ratio at birth in families with previous girls is worse than those with a boy. Our aim was to prospectively study in a large maternal and child unit sex-ratio against previous birth sex and use of traditional medicines for sex selection. MAIN OUTCOME MEASURES: Sex-ratio among mothers in families with a previous girl and in those with a previous boy, prevalence of indigenous medicine use and sex-ratio in those using medicines for sex selection. RESULTS: Overall there were 806 girls to 1000 boys. The sex-ratio was 720:1000 if there was one previous girl and 178:1000 if there were two previous girls. In second children of families with a previous boy 1017 girls were born per 1000 boys. Sex-ratio in those with one previous girl, who were taking traditional medicines for sex selection, was 928:1000. CONCLUSION: Evidence from the second children clearly shows the sex-ratio is being manipulated by human interventions. More mothers with previous girls tend to use traditional medicines for sex selection, in their subsequent pregnancies. Those taking such medication do not seem to be helped according to expectations. They seem to rely on this method and so are less likely use more definitive methods like sex selective abortions. This is the first such prospective investigation of sex ratio in second children looked at against the sex of previous children. More studies are needed to confirm the findings.

    Nuclear medicine imaging studies involve evaluation of a large amount of image data. Digital signal processing techniques have introduced processing algorithms that increase the information content of the display. Nuclear medicine imaging studies require interactive selection of suitable form of display and pre-display processing. Static imaging study requires pre-display processing to detect focal defects. Point operations (histogram modification) along with zoom and capability to display more than one image in one screen is essential. This album mode of display is also applicable to dynamic, MUGA and SPECT data. Isometric display or 3-D graph of the image data is helpful in some cases e.g. point spread function, flood field data. Cine display is used on a sequence of images e.g. dynamic, MUGA and SPECT imaging studies -to assess the spatial movement of tracer with time. Following methods are used at the investigator's discretion for inspection of the 3-D object. 1) Display of orthogonal projections, 2) Display of album of user selected coronal/ sagital/ transverse orthogonal slices, 3) Display of three orthogonal slices through user selected point, 4) Display of a set of orthogonal slices generated in the user-selected volume, 5) Generation and display of 3-D shaded surface. 6) Generation of volume data and display along with the 3-D shaded surface, 7) Side by side display orthogonal slices of two 3-D objects. Displaying a set of two-dimensional slices of a 3-D reconstructed object through shows all the defects but lacks the 3-D perspective. Display of shaded surface lacks the ability to show the embedded defects. Volume display -combining the 3-D surface and gray level volume data is perhaps the best form of display. This report describes these forms of display along with the theory. (author)

    Full Text Available For the overall development of medicinal plants cultivation in Iran, there is a need to identify various effective factors on medicinal plant cultivation. A proper method for identifying the most effective factor on the development of the medicinal plants cultivation is essential. This research conducted in order to prioritizing of the effective criteria for the development of medicinal plant cultivation in North Khorasan province in Iran using Analytical Network Process (ANP method. The multi-criteria decision making (MCDM is suggested to be a viable method for factor selection and the analytic network process (ANP has been used as a tool for MCDM. For this purpose a list of effective factors offered to expert group. Then pair wise comparison questionnaires were distributed between relevant researchers and local producer experts of province to get their opinions about the priority of criteria and sub- criteria. The questionnaires were analyzed using Super Decision software. We illustrated the use of the ANP by ranking main effective factors such as economic, educational-extension services, cultural-social and supportive policies on development of medicinal plants. The main objective of the present study was to develop ANP as a decision making tool for prioritizing factors affecting the development of medicinal plants cultivation. Results showed that the ANP methodology was perfectly suited to tackling the complex interrelations involved in selection factor in this case. Also the results of the process revealed that among the factors, supporting the cultivation of medicinal plants, build the infrastructure for marketing support, having educated farmer and easy access to production input have most impact on the development of medicinal plant cultivation.

    Given the importance of health insurance for financing medicines and recent policy changes designed to reduce health-related out-of-pocket expenditure (OOPE) in Mexico, our study examined and analyzed the effect of health insurance on the probability and amount of OOPE for medicines and the proportion spent from household available expenditure (AE) funds. We conducted a cross-sectional analysis by using the Mexican National Household Survey of Income and Expenditures for 2008. Households were grouped according to household medical insurance type (Social Security, Seguro Popular, mixed, or no affiliation). OOPE for medicines and health costs, and the probability of occurrence, were estimated with linear regression models; subsequently, the proportion of health expenditures from AE was calculated. The Heckman selection procedure was used to correct for self-selection of health expenditure; a propensity score matching procedure and an alternative procedure using instrumental variables were used to correct for heterogeneity between households with and without Seguro Popular. OOPE in medicines account for 66% of the total health expenditures and 5% of the AE. Households with health insurance had a lower probability of OOPE for medicines than their comparison groups. There was heterogeneity in the health insurance effect on the proportion of OOPE for medicines out of the AE, with a reduction of 1.7% for households with Social Security, 1.4% for mixed affiliation, but no difference between Seguro Popular and matched households without insurance. Medicines were the most prevalent component of health expenditures in Mexico. We recommend improving access to health services and strengthening access to medicines to reduce high OOPE.

    We used the Atrocities Documentation Survey to determine whether Sudanese government forces were involved in racially targeting sexual victimization toward ethnically African women in the Darfur region of western Sudan. The US State Department conducted the survey by interviewing a randomized multistage probability sample of 1136 Darfur refugees at 20 sites in Chad in 2004. For a subset of 932 respondents who had fled from village clusters that accounted for 15 or more respondents per cluster, we used hierarchical linear models to analyze village-level patterns of reported sexual violence. We statistically controlled for individual sexual victimization to remove bias. Respondents reported being subjected to racial epithets associated with sexual victimization significantly more often during combined attacks by Sudanese government forces and Janjaweed militia forces than during separate attacks by either force. Combined attacks by Sudanese government forces and Janjaweed militia forces led to racial epithets being used more often during sexual victimization in Darfur. Our results suggest that the Sudanese government is participating in the use of sexual assault as a racially targeted weapon against ethnically African civilians.

    2013-12-01

    Increasing scientific knowledge and technical innovations in the areas of cell biology, biotechnology and medicine resulted in the development of promising therapeutic approaches for the prevention and treatment of human diseases. Advanced therapy medicinal products (ATMPs) reflect a complex and innovative class of biopharmaceuticals as these products are highly research-driven, characterised by innovative manufacturing processes and heterogeneous with regard to their origin, type and complexity. This class of ATMP integrates gene therapy medicinal products, somatic cell therapy medicinal products and tissue engineering products and are often individualized and patient-specific products. Multiple challenges arise from the nature of ATMPs, which are often developed by micro, small and medium sized enterprises, university and academia, for whom regulatory experiences are limited and regulatory requirements are challenging. Regulatory guidance such as the reflection paper on classification of ATMPs and guidelines highlighting product-specific issues support academic research groups and pharmaceutical companies to foster the development of safe and effective ATMPs. This review provides an overview on the European regulatory aspects of ATMPs and highlights specific regulatory tools such as the ATMP classification procedure, a discussion on the hospital exemption for selected ATMPs as well as borderline issues towards transplants/transfusion products.

    Full Text Available The dissolution test is an essential tool to assess the quality of herbal medicines in the solid dosage form for oral use. This work aimed to evaluate the dissolution behavior of three herbal medicines in the form of capsules and tablet containing Passiflora, produced with powder or dried extract. Assay of total flavonoids and dissolution methods were validated and obtained results allowed the quantification of flavonoids with precision, accuracy and selectivity. The percentage of total flavonoids found was 2% for capsule A (containing only powder, 0.97% for capsule B (containing only dried extract and 5.5% for tablet. Although the content was lower, the release of flavonoids present in the capsule containing dried extract was 12% higher over 30 min, with dissolved percentage values of 87 and 75, for the capsules containing extract and powder, respectively. The tablet containing dried extract presented dissolution of 76%, despite the higher content of flavonoids, which may be due to pharmacotechnical problems. Obtained data demonstrated the need to implement these tests in the quality control of herbal medicines, confirming the release of the active ingredients that underlie the pharmacological action of these medicines.

  10. Potentials for progress in laser medicine

    Lasers could come to occupy a highly important position in the armament of medicine. They are the brightest known sources of light, man-made or natural, and emit light having such properties as coherence and monochromaticity. Furthermore, lasers have the ability to deliver very brief pulses of light which can cause unique alterations in biological materials. The major obstacle to the increased use of lasers in medicine and surgery is not the availability of laser devices, but the dearth of basic information about laser-tissue interactions. We have recently demonstrated that, even in turbid tissue such as the dermis, it is possible simultaneously to induce microscopically selective thermal damage, localized to millions of selectively absorbing targets, while sparing surrounding tissues. These targets may be as small as organelles or as large as blood vessels. Such localized thermal damage is truly unique to pulsed laser exposures. The scope and medical utility of these lesions has yet to be fully understood. Thus, there is much research to be done in describing and characterizing laser-induced injury. There is, however, ample evidence that several laser therapies could be improved by using selectively absorbed, short pulses that lead to the spatial confinement of thermal injury. Treatment of port wine stains, pigmented lesions, atheromatous arterial plaques, and the fragmentation of kidney and gall stones are examples. It should also be possible to use a variety of systems to deliver exogenous laser targets on or within individual types of cells or organelles. Such chromophores may lead to new forms of cancer therapy, for example

    Complementary and alternative medicine (CAM) has gained increasing popularity over the last several decades internationally, leading to an increasing interest from decision makers and researchers as to how to assess the effectiveness of CAM. The attempts, however, have been unsatisfactory. The most important reason is a lack of attention to the theoretical characteristics of CAM, which are completely different from those of allopathic medicine or biomedicine. This study attempted to survey expert Traditional Chinese Medicine (TCM) practitioners in China to elucidate critical issues when assessing the effectiveness of TCM. A questionnaire (with 20 close-ended and 2 open-ended questions) about the influencing factors of measuring the cost and effectiveness of TCM was distributed to TCM practitioners who had been working in the field of research for at least 5 years and had published at least one related scientific article in the last 5 years. Internal consistency test was performed for all questions to verify the reliability of the questionnaire. Principal-component analysis was performed for remaining items after Kaiser-Meyer-Olkin (KMO) index and Bartlett's test of sphericity. A linear combination model was then built to evaluate the contribution of various factors involved for the selection of TCM into the health care reimbursement or insurance system. Of 429 questionnaires issued, 137 were returned from respondents from 31 medical and research institutions, giving a recovery rate of 31.93%. Internal consistency coefficient obtained was 0.745, indicating good reliability of this measurement scale, and the data passed the KMO test and Bartlett's test of sphericity (KMO index = 0.691). In addition, eight common factors were extracted after the rotation of principal-component analysis with a cumulative variance of 70.92%. Our findings suggested that factors to be considered during the selection of TCM in health care reimbursement or insurance system include patient

    The article is devoted to the comprehensive analysis of scientific, practical and legal issues of personalized medicine that is a rapidly developing science-driven approach to healthcare. It is concluded that there is lack of general legal framework for the encouragement of scientific researches and practical implementation in this field. The article shows foreign experience and prospects for the introduction of personalized medicine as a key concept of healthcare system, which is based on a selection of diagnostic, therapeutic and preventive measures that would be the most effective for a particular person in view of individual characteristics. The conclusions and proposals to improve the current legislation and development of personalized medicine in Ukraine are suggested.

    India has a rich country for the uses of Ayurvedic medicinal plants for treatment and also the north- Karnataka boasts an unparallel diversity of medicinal plants. The present study attempts to estimate and compare the level of trace and heavy metals in some selected leaves and root samples of Ayurvedic medicinal plants such as Mg, Al, K, Cr, Mn, Fe, Cu, Zn, and Cd. The samples are collected from different places of North-Karnataka regions and sample solutions prepared as the ratio of 1:25:25+950ml=1000ppm.the trace and heavy elemental concentration was estimated using Atomic Absorption Spectrometric (AAS) Method. The average concentrations of Mg, Mn, Fe and Zn, are ranging from 2ppm to 5250.2ppm and potassium (K) has more concentration as compare to all other. The other elements likes Al, Cr, Cu, and Cd were also estimed and presented in the table. Therefore, these medicinal plants are rich in some essential minerals, especially K, Mg, Mn, Fe and Zn which are essential for human health

  17. Individual Biomarkers Using Molecular Personalized Medicine Approaches.

    Molecular personalized medicine tries to generate individual predictive biomarkers to assist doctors in their decision making. These are thought to improve the efficacy and lower the toxicity of a treatment. The molecular basis of the desired high-precision prediction is modern "omex" technologies providing high-throughput bioanalytical methods. These include genomics and epigenomics, transcriptomics, proteomics, metabolomics, microbiomics, imaging, and functional analyses. In most cases, producing big data also requires a complex biomathematical analysis. Using molecular personalized medicine, the conventional physician's check of biomarker results may no longer be sufficient. By contrast, the physician may need to cooperate with the biomathematician to achieve the desired prediction on the basis of the analysis of individual big data typically produced by omex technologies. Identification of individual biomarkers using molecular personalized medicine approaches is thought to allow a decision-making for the precise use of a targeted therapy, selecting the successful therapeutic tool from a panel of preexisting drugs or medical products. This should avoid the treatment of nonresponders and responders that produces intolerable unwanted effects. © 2017 S. Karger AG, Basel.

    The 9 (th) Revision of German Medical Licensing Regulations for Physicians has come into effect on October 1 (st) 2003. Social medicine was separated into the fields "occupational health, social medicine" and the various cross-sectional modules: epidemiology, biometry, medical computer science; health economics, health-care system, public health; prevention, health promotion; rehabilitation, physical medicine, naturopathic treatment. This paper studies the realisation of teaching in the field social medicine at German medical faculties. The survey was conducted in collaboration with the German Association for Social Medicine and Prevention (DGSMP). A survey was conducted at 38 institutes of 36 German medical faculties. The written questionnaire contained mostly selection items in which chances and barriers of the field were queried with supply items. Information about time scale, general conditions and resources was aked for. On the basis of the guidelines of the DGSMP, the topics to be taught were evaluated concerning their relevance and integration into education. The response rate was 68% (n=26). Social insurance, basic principles, responsibility in the Social Security Code and the different providers were judged as the most important topics. There was a strong demand for lecturing material. 82% (n=18) of the faculties wished to have specific material, for example e-learning, examples, lesson plans, curricula and also textbooks. 91% (n=19) of the faculties requested an exchange of information between the faculties concerning educational contents, motivation of students and e-learning. The realisation of teaching is different between the faculties concerning the number of hours, teaching methods and number of students per year. The motivation of the students is one of the problems, but also the lack of acceptance within the clinic. Specific resources and exchange between the faculties are necessary concerning e-learning, which is offered at only few faculties so

    The advent of evolutionary medicine in the last two decades has provided new insights into the causes of human disease and possible preventative strategies. One of the strengths of evolutionary medicine is that it follows a multi-disciplinary approach. Such an approach is vital to future biomedicine as it enables for the infiltration of new ideas. Although evolutionary medicine uses Darwinian evolution as a heuristic for understanding human beings' susceptibility to disease, this is not necessarily in conflict with Islamic medicine. It should be noted that current evolutionary theory was first expounded by various Muslim scientists such as al-Jāḥiẓ, al-Ṭūsī, Ibn Khaldūn and Ibn Maskawayh centuries before Darwin and Wallace. In this way, evolution should not be viewed as being totally antithetical to Islam. This article provides a comparative overview of Islamic medicine and Evolutionary medicine as well as drawing points of comparison between the two approaches which enables their possible future integration.
