RESUMO
OBJECTIVE: Posterior circulation ischemic stroke (PCiS) constitutes 20-30% of ischemic stroke cases. Detailed information about differences between PCiS and anterior circulation ischemic stroke (ACiS) remains scarce. Such information might guide clinical decision making and prevention strategies. We studied risk factors and ischemic stroke subtypes in PCiS vs. ACiS and lesion location on magnetic resonance imaging (MRI) in PCiS. METHODS: Out of 3,301 MRIs from 12 sites in the National Institute of Neurological Disorders and Stroke (NINDS) Stroke Genetics Network (SiGN), we included 2,381 cases with acute DWI lesions. The definition of ACiS or PCiS was based on lesion location. We compared the groups using Chi-squared and logistic regression. RESULTS: PCiS occurred in 718 (30%) patients and ACiS in 1663 (70%). Diabetes and male sex were more common in PCiS vs. ACiS (diabetes 27% vs. 23%, p < 0.05; male sex 68% vs. 58%, p < 0.001). Both were independently associated with PCiS (diabetes, OR = 1.29; 95% CI 1.04-1.61; male sex, OR = 1.46; 95% CI 1.21-1.78). ACiS more commonly had large artery atherosclerosis (25% vs. 20%, p < 0.01) and cardioembolic mechanisms (17% vs. 11%, p < 0.001) compared to PCiS. Small artery occlusion was more common in PCiS vs. ACiS (20% vs. 14%, p < 0.001). Small artery occlusion accounted for 47% of solitary brainstem infarctions. CONCLUSION: Ischemic stroke subtypes differ between the two phenotypes. Diabetes and male sex have a stronger association with PCiS than ACiS. Definitive MRI-based PCiS diagnosis aids etiological investigation and contributes additional insights into specific risk factors and mechanisms of injury in PCiS.

PURPOSE: Risk management in the healthcare sector is a highly relevant sub-domain and a crucial research area from the humanitarian perspective. The purpose of this paper is to focus on the managerial/supply chain risk factors experienced by the government hospitals in an Indian state. The present paper analyzes the inter-relationships among the significant risk factors and ranks those risk factors based on their criticality. DESIGN/METHODOLOGY/APPROACH: The current research focuses on 125 public hospitals in an Indian state. Questionnaire-based survey and personal interviews were conducted in the healthcare sector among the inpatients and hospital staff to identify the significant risk factors. An integrated DEMATEL-ISM-PROMETHEE method is adopted to analyze the impact potential and dependence behavior of the risk factors. FINDINGS: The analysis asserts the absence of critical risk factors that have a direct impact on patient safety in the present healthcare system under investigation. However, the results illustrate the remarkable impact potential attributed to the risk factor, namely, staff shortage in inducing other risk factors such as employee attitudinal issues, employee health issues and absenteeism altogether resulting in community mistrust/misbeliefs. Maintenance mismanagement, monsoon time epidemics, physical infrastructure limitations are also found to be significant risk factors that compromise patient satisfaction levels. PRACTICAL IMPLICATIONS: Multiple options are illustrated to mitigate significant risk factors and operational constraints experienced by public hospitals in the state. The study warrants urgent attention from government officials to fill staff vacancies and to improve the infrastructural facilities to match with the increasing demand from the society. Furthermore, this research recommends the hospital authorities to start conducting induction and training programs for the hospital employees to instill the fundamental code of conduct while working in hectic, challenging and even in conditions with limited resources. ORIGINALITY/VALUE: Only limited papers are visible that address the identification and mitigation of risk factors associated with hospitals. The present paper proposes a novel DEMATEL-ISM-PROMETHEE integrated approach to map the inter-relationships among the significant risk factors and to rank those risk factors based on their criticality. Furthermore, the present study discloses the unique setting of the public healthcare system in a developing nation.

OBJECTIVE: The aim of this study was to compare the use of semi-automated (Medax Velox 2; Poggio Rusco, Italy) and automated (Bard Magnum Biopsy Instrument; Covington, GA, USA) core biopsy needles, for ultrasound guided breast biopsy. MATERIALS AND METHODS: A 14G semi-automatic spring loaded core biopsy needle with a 22-mm-throw (Medax Velox 2; Poggio Rusco, Italy) and 14-gauge automated needle device with a 22-mm-throw biopsy gun (Bard-Magnum Biopsy Instrument, Covington, GA, USA) were used for breast biopsies under ultrasound guidance on alternate months during the study period between July 2009 and May 2011. One hundred and sixty lesions were biopsied and specimens were sent for histological evaluation. RESULTS: The automated needle obtained a higher number of histology reports at 84% (67/80) as compared with the semiautomated needle at 60% (48/80) (Fisher exact test, p value=0.023). Inadequate samples with the automated needle were much less at 9% (7/60) than with the semiautomated needle at 23% (18/60) (Fisher exact test, p value=0.028). The semi-automated needle showed slightly less fragmented samples. However, the number of fragmented samples with definitive diagnosis was slightly higher with the automated compared with the semiautomated needle, at 16% (13/80) and 13% (10/80) respectively. Compared with histology of 29 lesions that were excised, the semi-automated needle had higher sensitivity (100%) but lower specificity (75%) and accuracy (90%) compared with the automated needle (88% sensitivity, 100% specificity, 95% accuracy). CONCLUSION: Definitive diagnosis from the study samples slightly favours the use of automated core biopsy needle as compared to semi-automated core biopsy needle.
RESUMO
The generation of patient-specific pluripotent stem cells has the potential to accelerate the implementation of stem cells for clinical treatment of degenerative diseases. Technologies including somatic cell nuclear transfer and cell fusion might generate such cells but are hindered by issues that might prevent them from being used clinically. Here, we describe methods to use dermal fibroblasts easily obtained from an individual human to generate human induced pluripotent stem (iPS) cells by ectopic expression of the defined transcription factors KLF4, OCT4, SOX2, and C-MYC. The resultant cell lines are morphologically indistinguishable from human embryonic stem cells (HESC) generated from the inner cell mass of a human preimplantation embryo. Consistent with these observations, human iPS cells share a nearly identical gene-expression profile with two established HESC lines. Importantly, DNA fingerprinting indicates that the human iPS cells were derived from the donor material and are not a result of contamination. Karyotypic analyses demonstrate that reprogramming of human cells by defined factors does not induce, or require, chromosomal abnormalities. Finally, we provide evidence that human iPS cells can be induced to differentiate along lineages representative of the three embryonic germ layers indicating the pluripotency of these cells. Our findings are an important step toward manipulating somatic human cells to generate an unlimited supply of patient-specific pluripotent stem cells. In the future, the use of defined factors to change cell fate may be the key to routine nuclear reprogramming of human somatic cells.

The effect of different triazole compounds, viz., triadimefon (TDM) and hexaconazole (HEX) treatments on the antioxidant metabolism of Solenostemon rotundifolius Poir., Morton plants was investigated in the present study under pot culture. Plants were treated with TDM at 15 mg l(-1) and HEX at 10 mg l(-1) separately by soil drenching on 80, 110 and 140 days after planting (DAP). The plants were harvested randomly on 90, 120 and 150 DAP for determining the effect of both the triazoles on non-enzymatic antioxidant contents like ascorbic acid (AA), reduced glutathione (GSH) and alpha-tocopherol (alpha-toc), activities of antioxidant enzymes like superoxide dismutase (SOD) and ascorbate peroxidase (APX). All the analyses were made in leaf, stem and tubers of both control and treated plants. It was found that both these triazole compounds have profound effects on the antioxidant metabolism and caused an enhancement in both non-enzymatic and enzymatic antioxidant potentials under treatments. These results suggest that, the application of triazoles may be a useful tool to increase the antioxidant production in S. rotundifolius and thereby make it an economical food crop.

The variations in antioxidant potentials and indole alkaloid content were studied in the present investigation, in two varieties (rosea and alba) of Catharanthus roseus, an important herb used in traditional as well as modern medicine, exposed to water deficit stress. The antioxidant and alkaloid profiles were estimated from root, stem, leaf, flowers and pods. The antioxidant potentials were examined in terms of non-enzymatic antioxidant molecules and activities of antioxidant enzymes. The non-enzymatic antioxidant molecules studied were ascorbic acid (AA), alpha-tocopherol (alpha-toc) and reduced glutathione (GSH). The estimated antioxidant enzymes were superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT), peroxidase (POX) and polyphenol oxidase (PPO). The antioxidant concentrations and activities of antioxidant enzymes were high under water deficit stress in all parts of the plants. Indole alkaloid content was high in the roots of rosea variety in response to stress when compared to alba variety.

The effects of two triazole compounds, triadimefon and hexaconazole, on the growth and carbohydrate metabolism were studied in Solenostemon rotundifolius Poir., Morton plants under pot culture. Plants were treated with triadimefon at 15mg l(-1) and hexaconazole at 10mg l(-1) separately by soil drenching on 80, 110 and 140 days after planting (DAP). The plants were harvested randomly and growth parameters were studied on 90, 120 and 150 DAP for determining the effect of both the triazole on growth and chlorophyll pigments. These triazole compounds increased the chlorophyll pigments. However, both the treatments decreased the fresh and dry weights of shoot and leaf area. Both these triazole resulted in a marginal increase in starch content and decreased the sugar contents. The carbohydrate metabolizing enzymes alpha- and beta-amylase activities were reduced and invertase activity increased in S. rotundifolius under triadimefon and hexaconazole treatments.

We have examined the changes in carbohydrate metabolism in food yam (Dioscorea esculenta (Lour.) Burk.) tubers and in an economically important spice cum medicinal plant turmeric (Curcuma longa L.) rhizomes under storage. Both specimens showed varied levels of dormancy and sprouting appeared at the end of dormant period. Harvested, fully matured tubers of yam and rhizomes of turmeric were stored in wooden boxes under the conditions of 28+/-2 degrees C temperature and 65-75% relative humidity (RH) in dark. The starch, sugars, enzymes of starch degradation, respiration, glycolysis, tricarboxylic acid (TCA) cycle and oxidative pentose phosphate pathway (PPP) were studied during 1-70 days after harvest (DAH). This investigation revealed that, the starch degradation and the enzymes involved, viz. alpha-amylases and starch phosphorylase showed a lower level of activity during early period of dormancy, while sugar content and enzymes of carbohydrate metabolism increased rapidly during sprouting. The isoenzymic profiles of alpha-amylases showed marked variations in these two phases. The key enzymes of glycolysis, TCA cycle and PPP, viz. aldolase, succinic dehydrogenase, malic dehydrogenase, glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase were increased even before the visible appearance of sprouting and their activities were at their maximum during sprouting. Based of the observations the dormancy period may be distinctly divided into peak period of rest and presprouting period.

In the present study, a pot culture experiment was conducted to estimate the ameliorating effect of propiconazole (PCZ) on drought stress in cowpea (Vigna unguiculata (L.) Walp.) plants. From 30 days after sowing (DAS), the plants were subjected to 3, 6 and 9 days interval drought (DID) stress and drought stress with PCZ at 15 and 15 mg l(-1) PCZ alone and 1 day interval irrigation was kept as control. The plant samples were collected on 34 DAS (3 DID), 37 DAS (6 DID) and 40 DAS (9 DID). The plants were separated into root, stem and leaf for estimating the antioxidant contents and activities of antioxidant enzymes. Individual and combined drought stress and PCZ treatments increased ascorbic acid (AA), alpha-tocopherol (alpha-toc) contents, superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT) and polyphenol oxidase (PPO) activities when compared to control. The PCZ treatment mitigated the adverse effects of drought stress by increasing the antioxidant potentials and thereby paved the way for overcoming drought stress in V. unguiculata plants.

PURPOSE: To estimate the prevalence of epilepsy in India by meta-analysis of previously published and unpublished studies and to determine patterns of epilepsy by using community-based studies. METHODS: We attempted to identify as many previously published and unpublished studies as possible on the prevalence of epilepsy in India. The studies were assessed with regard to methods and definitions. The prevalence rates for rural and urban populations and for men and women were calculated with a 95% confidence interval (CI). The studies that provided details on age structure, age-specific rates, and patterns of epilepsy were chosen for meta-analysis. Both crude values and age-standardized prevalence rates were calculated after accounting for heterogeneity. RESULTS: Twenty studies were found involving a sample population of 598,910, among whom 3,207 had epilepsy. This resulted in a crude prevalence of 5.35/1,000. After a correction for heterogeneity due to interstudy variation, the overall prevalence per 1,000 (and its 95% CI) was 5.33 (4.25-6.41); with urban areas at 5.11 (3.49-6.73); rural areas, 5.47 (4.04-6.9); men, 5.88 (3.89-7.87); and women 5.51 (3.49-7.53). After correction for the variability in estimates of heterogeneity, age-standardized rates (from five studies) revealed that the prevalence rates per 1,000 (and the 95% CI), were as follows: overall, 5.59 (4.15-7.03); men, 6.05 (3.79-8.31); women, 5.18 (3.04-7.32); urban, 6.34 (3.43-9.25); rural, 4.94 (3.12-6.76). Urban men and women had a higher prevalence of epilepsy compared with rural ones, however the difference was not statistically significant. Age-specific prevalence rates were higher in the younger age group, with the onset of epilepsy reported mostly in the first three decades of the sample population's lives. The treatment gap (i.e., the percentage of those with epilepsy who were receiving no or inadequate treatment) was more than 70% in the rural areas. CONCLUSIONS: Based on the total projected population of India in the year 2001, the estimated number of people with epilepsy would be 5.5 million. Based on a single study on the incidence of epilepsy, the number of new cases of epilepsy each year would be close to half a million. Because rural population constitutes 74% of the Indian population, the number of people with epilepsy in rural areas will be approximately 4.1 million, three fourths of whom will not be getting any specific treatment as per the present standard.

The conformational preference of A and B rings in four differently functionalized bromosubstituted 4-en-3-one steroids is studied by concerted application of high-resolution one- and two-dimensional nuclear magnetic resonance (NMR) techniques, such as homonuclear and heteronuclear correlated spectroscopy, transient and steady-state nOe spectroscopy, temperature-dependent chemical chemical shift variation, and application of a modified Karplus equation. The steroids studied include 6 beta-bromocholest-4-en-3-one (3), 4,6 beta-dibromocholest-1,4-dien-3-one (2), 2 alpha,4,6 beta-tribromocholest-4-en-3-one (1), and (25R)-2 alpha,6 beta-dibromospirost-4-en-3-one (4). Steroids 1-4 were prepared by either acid-catalyzed or free-radical bromination from appropriate 4-en-3-one steroid. The study has yielded an insight into the factors responsible for conformational preferences of the A and B rings of these bromosubstituted steroids. Bromosubstitution at the 2 alpha position is responsible for the inversion of the A ring to inverted 1 beta,2 alpha-halfchair conformation. The electronic interaction between 4-bromine and carbonyl oxygen distorts the A-ring conformation further. Inversion of the A ring has a concomitant effect of distortion in the chair form of the B ring. Conformational preferences of A and B rings are not found to be influenced by transmission effect of a side chain or oxygenated ring system. Temperature-dependent NMR studies indicate the reduced conformational flexibility of the A ring for 2 alpha-bromosubstituted steroids. Complete assignment of the 13C and 1H resonances of two of the steroids studied (3 and 4) is presented.

RESUMO
Case control analysis of 204 patients with acute ischemic stroke revealed the matched pair odds ratio (and 95% confidence limits) for hypertension, ECG abnormality, heart disease of any type, diabetes, smoking and alcohol intake to be 3.95 (2.5, 6.2), 2.1 (1.4, 3.1), 2.1 (1.4, 3.2), 1.7 (1.1, 2.6), 1.8 (1.1, 2.8) and 1.5 (0.86, 2.6), respectively. Except alcohol intake, the other factors were statistically significant. Hemoglobin, packed cell volume (hematocrit), serum cholesterol, triglycerides and low-density lipoprotein cholesterol levels were not found to be significant. High-density lipoprotein (HDL) cholesterol and uric acid were significantly lower and the ratio of total cholesterol to HDL cholesterol (TC/HDL) was higher among stroke patients. The risk was considerably higher when there was any combination of hypertension, heart disease and HDL cholesterol level lower than 45 mg/dl. Logistic regression revealed hypertension, heart disease of any type, lower HDL cholesterol and uric acid and higher ratio of TC/HDL to be significant factors.

A unique photometer capable of measuring line intensities of <0.1% of the bright background continuum (5 x 10(6)/A) has been developed and successfully commissioned for the measurement of daytime OI 630.0-nm emission from the thermosphere. The photometer employs a low resolution (10(4)) Fabry-Perot etalon, temperature tuned narrowband (3-A) interference filter, radial chopper, and up/down counting system. The optimum choice of the photometer parameters and a unique method of eliminating the background enabled us to overcome the limitations of the earlier attempts to make measurements on such phenomena as dayglow and has opened up a wide range of uses. However, at present, it is being discussed only in the context of dayglow measurements.
RESUMO
An intensive search for 2 years for patients with Bell's palsy, conducted through the polyclinics, university hospitals and physiotherapy centres in Benghazi, revealed a total of 242 cases. The average annual incidence per 100,000 population was 23.35 and the age-adjusted incidence 35.72. The incidence increased with age up to the sixth decade. Seasonal clustering was noted in the months of December and January. Hypertension and diabetes mellitus were associated in 4.1% and 7% of patients, respectively. Only four patients presented during pregnancy. Recurrent facial paralysis was encountered in 5.4% of patients and was characterized by male preponderance and a tendency to recur more frequently on the same side as the initial paralysis. Familial incidence and bilateral involvement were rare features. Twelve per cent of patients who were followed up had moderate to severe residual weakness.

During a 12 month study period, a total of 329 incident cases of stroke occurred in Benghazi, Libya. This provided an unadjusted annual incidence rate for stroke of 63 per 100,000 population; the corresponding rates for the male and female were 69 and 58 per 100,000 respectively. The sex dependent difference in the incidence was not statistically significant. Cerebral infarction was the commonest type of stroke accounting for 80.9%. The incidence rates increased with age in all categories of stroke. Hypertension and ischaemic heart disease were common risk factors among the male patients, while diabetes and hypercholesterolaemia were more frequent in the female patients.

Out of 329 cases of stroke registered in Benghazi between November 1, 1983 and October 30, 1984, 63 patients comprising 32 males and 31 females belonged to the 15-40-year age group (stroke in the young). The annual age-specific crude incidence of stroke in the young was 39.3 and 40.3 per 100,000 for men and women, respectively. The age-adjusted incidence rate for both sexes for the age-specific (15-40 years) population was 47 per 100,000. The sex-dependent difference in the incidence was not statistically significant. These results emphasize that the high incidence of stroke in the young in Benghazi is not a reflection of the age distribution of the population. Hypertension, diabetes mellitus, heart disease and hypercholesterolemia were important components of high stroke profile in the young. One or more risk factors were identified in 78% of total young stroke victims and in all the patients under the age of 30. Eight young stroke subjects died during the study period.
