Epidemiology and effects of sociodemographic factors on extrapulmonary tuberculosis in Ambala, India.

BACKGROUND: An ambitious plan was set into motion with the aim of TB elimination from India in 2025. To achieve this, it is high time to give emphasis on other prevalent forms of TB, such as extra pulmonary TB (EPTB). OBJECTIVES: The study aims to discern the differences in patient characteristics and management practices between pulmonary TB and EPTB using data from district Ambala. METHODS: This retrospective study used data of 12,985 TB patients from district Ambala, India. The differences in patient characteristics and management practices between pulmonary TB and EPTB were analyzed using the NIKSHAY database. RESULTS: In the studied population, extra pulmonary TB (EPTB) formed 29.7% of all TB cases. Among all EPTB cases, pleural TB was found to be the most common form, accounting for 27%. The study also revealed that female gender, young age, non-diabetic status, and high BMI were associated with an increased propensity to have EPTB. Interestingly, unlike pulmonary TB, which had increased odds for contracting the disease in diabetic individuals (OR - 2.02), there were no increased odds for contracting EPTB in diabetic individuals. However, HIV infection significantly increased the odds for both pulmonary TB and EPTB. The results also showed diagnostic discrepancies between the private and public sectors, along with a low microbiological confirmation rate of 7.1% in EPTB cases. CONCLUSION: The study highlights the importance of focusing on EPTB in addition to pulmonary TB for effective TB elimination in India. The differences in patient characteristics and management practices warrant further investigation and targeted interventions for both forms of the disease. Efforts should be made to improve diagnostic accuracy and reduce discrepancies between the private and public sectors.

Husband's involvement in utilization of maternal health services by their spouse in district Rohtak, Haryana.

Introduction: Husband and wife as a couple are fully responsible for their current and future. In our society, the husband is mostly responsible for making the decision regarding any expenses. In India, there is a need to reduce the maternal mortality rate, and Husband's involvement in antenatal care could be a key to success as it will enable them to support their partner in adequate preparation for birth and to utilize emergency obstetric care early if complications arise. Aim and Objectives: To find out about male involvement in the utilization of maternal healthcare services by their spouse and various factors affecting male involvement in the utilization of maternal healthcare services. Methods: This study was conducted in urban and rural field practice areas attached to the Department of Community Medicine, PGIMS, Rohtak. The study included 400 couples where 200 each were recruited from rural and urban areas. Out of 17 subcenters under CHC Chiri eight, subcenters were selected randomly by lottery method. A line list of these couples was prepared at each subcenter using ANC and birth register. Couples were enrolled from this line list till a sample size of 25 was reached at each of these eight subcenters. In this way, a total of 200 couples were enrolled from rural areas in which women delivered and availed maternal health services in the last 6 months. In urban areas, an equal number of couples were enrolled from each of these three urban health posts till the sample size of 200 was reached in an urban area. Results: The majority of the husbands (73%) reported that they participated in their wives' utilization of maternal health services. Twenty-seven percent did not participate in their wives' utilization of maternal health services. It also showed that 71.0% of the husbands did not know about the investigations that needed to be performed during a woman's pregnancy. Only 29% were aware of it. On analysis, it was observed that 73% of the husbands had good participation in their spouses' maternal and child health (MCH) care, while the rest had poor participation (27%). It also showed that as the education level of the participants' husbands increased, their participation in their spouses' MCH care increased, with the highest being observed among graduates (91.3%) and the lowest among those with primary schooling level education (66.7%) which were statistically significant.

Host Plant Modulated Physio-Biochemical Process Enhances Adaptive Response of Sandalwood (Santalum album L.) under Salinity Stress.

Salinity is one of the most significant abiotic stress that affects the growth and development of high-value tree species, including sandalwood, which can also be managed effectively on saline soils with the help of suitable host species. Therefore, the current investigation was conducted to understand the physiological processes and antioxidant mechanisms in sandalwood along the different salinity gradients to explore the host species that could support sandalwood growth in salt-affected agro-ecosystems. Sandalwood seedlings were grown with ten diverse host species with saline water irrigation gradients (ECiw~3, 6, and 9 dS m-1) and control (ECiw~0.82 dS m-1). Experimental findings indicate a decline in the chlorophyll content (13-33%), relative water content (3-23%), photosynthetic (27-61%) and transpiration rate (23-66%), water and osmotic potential (up to 137%), and ion dynamics (up to 61%) with increasing salinity levels. Conversely, the carotenoid content (23-43%), antioxidant activity (up to 285%), and membrane injury (82-205%) were enhanced with increasing salinity stress. Specifically, among the hosts, Dalbergia sissoo and Melia dubia showed a minimum reduction in chlorophyll content, relative water content, and plant water relation and gas exchange parameters of sandalwood plants. Surprisingly, most of the host tree species maintained K+/Na+ of sandalwood up to moderate water salinity of ECiw~6 dS m-1; however, a further increase in water salinity decreased the K+/Na+ ratio of sandalwood by many-fold. Salinity stress also enhanced the antioxidative enzyme activity, although the maximum increase was noted with host plants M. dubia, followed by D. sissoo and Azadirachta indica. Overall, the investigation concluded that sandalwood with the host D. sissoo can be successfully grown in nurseries using saline irrigation water and, with the host M. dubia, it can be grown using good quality irrigation water.

Identification of sources of resistance to scald (Rhynchosporium commune) and of related genomic regions using genome-wide association in a mapping panel of spring barley.

Barley is an important crop worldwide known for its adaptation to harsh environments and used in multiple forms as feed, food and beverages. Its productivity is affected by major abiotic and biotic stresses. Scald caused by hemibiotrophic fungus Rhynchosporium commune is a major foliar disease in many parts of the world. Host plant resistance is targeted by breeders to efficiently control this disease. An association mapping panel of 316 spring barley genotypes (AM2017) was screened for seedling resistance in greenhouse against three R. commune isolates and for adult plant resistance in three field locations in Morocco. The phenotyping results showed different numbers of entries with resistant and moderately resistant reactions at both seedling and adult plant stages. The reactions differed between the isolates with the highest percentage of resistant genotypes observed for isolate SC-S611 (49.4%) and highest percentage of susceptible genotypes (73.8%) for isolate SC-1122. At adult plant stage, the highest percentage of scald resistant genotypes (64.5%) was observed at Rommani site compared to 56% at Guich site and only 28.8% at Marchouch site. Seven genotypes were resistant at the seedling and adult plant stages. Genome wide association study (GWAS) revealed 102 MTA (15 QTL) at the seedling stage, and 25 MTA (12 QTL) associated with scald resistance at the adult plant stage. In addition, the sequences of 92 out of 102 at SRT, and 24 out of 25 significant SNP markers at APR were located in genomic regions enriched with functional proteins involved in diverse cellular processes including disease resistance. These markers span over all chromosomes with the majority of SNPs located on 3H and 7H. This study has verified 18 QTL reported in previous studies. In addition, it was successful in identifying new sources of resistance and novel genomic regions which could help in enhancing scald resistance in barley breeding programs.

Epidemiological Profile and Spatio-Temporal Pattern of Infant Deaths in a District of North India during 2016-2019.

Background: Infant mortality is an important health indicator of a population given its strong link to socioeconomic status, health service access, and quality and maternal health. The declining trend of Infant Mortality Rate has been observed in India where it reduced from 89 deaths per 1000 live births in 1990 to 28 deaths per 1000d live births in 2019. Most of the studies regarding the trend of infant mortality are state-based, however, state-level infant mortality has masked the intradistrict clustering of individual infant deaths. Hence, this study was planned with an objective to study the trend of infant mortality at the district level. Material and Methods: A retrospective study was conducted in the district Rohtak of Haryana using the data collected regarding infant deaths. The collected data regarding addresses were geocoded. The resulting layer was then analyzed using QGIS v3.10. The descriptive data was analyzed using SPSS v20.0. Result: In total, 1336 infant deaths during the study period were included. A declining trend of infant mortality was observed over the study period. The number of grids (25 km2) reduced from 18 in 2016 to 10 in 2019 depicting a reduction in the areas with more than expected count. Conclusion: This study emphasizes on the importance of using the geographic information science technique in identifying local hotspots within the district so as to find areas that need more support and observation.

Characterization of Leaf Rust Resistance in International Barley Germplasm Using Genome-Wide Association Studies.

A panel of 114 genetically diverse barley lines were assessed in the greenhouse and field for resistance to the pathogen Puccinia hordei, the causal agent of barley leaf rust. Multi-pathotype tests revealed that 16.6% of the lines carried the all-stage resistance (ASR) gene Rph3, followed by Rph2 (4.4%), Rph1 (1.7%), Rph12 (1.7%) or Rph19 (1.7%). Five lines (4.4%) were postulated to carry the gene combinations Rph2+9.am, Rph2+19 and Rph8+19. Three lines (2.6%) were postulated to carry Rph15 based on seedling rust tests and genotyping with a marker linked closely to this gene. Based on greenhouse seedling tests and adult-plant field tests, 84 genotypes (73.7%) were identified as carrying APR, and genotyping with molecular markers linked closely to three known APR genes (Rph20, Rph23 and Rph24) revealed that 48 of the 84 genotypes (57.1%) likely carry novel (uncharacterized) sources of APR. Seven lines were found to carry known APR gene combinations (Rph20+Rph23, Rph23+Rph24 and Rph20+Rph24), and these lines had higher levels of field resistance compared to those carrying each of these three APR genes singly. GWAS identified 12 putative QTLs; strongly associated markers located on chromosomes 1H, 2H, 3H, 5H and 7H. Of these, the QTL on chromosome 7H had the largest effect on resistance response to P. hordei. Overall, these studies detected several potentially novel genomic regions associated with resistance. The findings provide useful information for breeders to support the utilization of these sources of resistance to diversify resistance to leaf rust in barley and increase resistance durability.

Au-courant and novel technologies for efficient doubled haploid development in barley (Hordeum vulgare L.).

Bounteous modern and innovative biotechnological tools have resulted in progressive development in the barley breeding program. Doubled haploids developed (homozygous lines) in a single generation is significant. Since the first discovery of haploid plants in 1920 and, in particular, after discovering in vitro androgenesis in 1964 by Guha and Maheshwari, the doubled haploidy techniques have been progressively developed and constantly improved. It has shortened the cultivar development time and has been extensively used in: genetic studies, gene mapping, marker/trait association, and QTL studies. In barley, the haploid occurrence developed gradually from being a sporadic and random process (spontaneous) to haploid development by in vivo method of modified pollination or by in vitro culture of immature male or female gametophytes. Although significant improvement in DH induction protocols has been made, challenges still exist for improvement in areas such as: low efficiency, albinism, genotypic specificity etc. Here, the paper focuses on: haploidization via different in vitro, in vivo techniques, the recent advances technologies like centromere-mediated haploidization, hap induction gene, and Doubled haploid CRISPR. The au-courant work of different researchers in barley using these technologies is reviewed. Studies on different factors affecting haploid induction and work on genome doubling of barley haploids to produce DH lines via spontaneous and induced technologies has also been highlighted.

CHSI costing study-Challenges and solutions for cost data collection in private hospitals in India.

INTRODUCTION: Ayushman Bharat Pradhan Mantri Jan Aarogya Yojana (AB PM-JAY) has enabled the Government of India to become a strategic purchaser of health care services from private providers. To generate base cost evidence for evidence-based policymaking the Costing of Health Services in India (CHSI) study was commissioned in 2018 for the price setting of health benefit packages. This paper reports the findings of a process evaluation of the cost data collection in the private hospitals. METHODS: The process evaluation of health system costing in private hospitals was an exploratory survey with mixed methods (quantitative and qualitative). We used three approaches-an online survey using a semi-structured questionnaire, in-depth interviews, and a review of monitoring data. The process of data collection was assessed in terms of time taken for different aspects, resources used, level and nature of difficulty encountered, challenges and solutions. RESULTS: The mean time taken for data collection in a private hospital was 9.31 (± 1.0) person months including time for obtaining permissions, actual data collection and entry, and addressing queries for data completeness and quality. The longest time was taken to collect data on human resources (30%), while it took the least time for collecting information on building and space (5%). On a scale of 1 (lowest) to 10 (highest) difficulty levels, the data on human resources was the most difficult to collect. This included data on salaries (8), time allocation (5.5) and leaves (5). DISCUSSION: Cost data from private hospitals is crucial for mixed health systems. Developing formal mechanisms of cost accounting data and data sharing as pre-requisites for empanelment under a national insurance scheme can significantly ease the process of cost data collection.

CGIAR Barley Breeding Toolbox: A diversity panel to facilitate breeding and genomic research in the developing world.

Breeding programs in developing countries still cannot afford the new genotyping technologies, hindering their research. We aimed to assemble an Association Mapping panel to serve as CGIAR Barley Breeding Toolbox (CBBT), especially for the Developing World. The germplasm had to be representative of the one grown in the Developing World; with high genetic variability and be of public domain. For it, we genotyped with the Infinium iSelect 50K chip, a Global Barley Panel (GBP) of 530 genotypes representing a wide range of row-types, end-uses, growth habits, geographical origins and environments. 40,342 markers were polymorphic with an average polymorphism information content of 0.35 and 66% of them exceeding 0.25. The analysis of the population structure identified 8 subpopulations mostly linked to geographical origin, four of them with significant ICARDA origin. The 16 allele combinations at 4 major flowering genes (HvVRN-H3, HvPPD-H1, HvVRN-H1 and HvCEN) explained 11.07% genetic variation and were linked to the geographic origins of the lines. ICARDA material showed the widest diversity as revealed by the highest number of polymorphic loci (99.76% of all polymorphic SNPs in GBP), number of private alleles and the fact that ICARDA lines were present in all 8 subpopulations and carried all 16 allelic combinations. Due to their genetic diversity and their representativity of the germplasm adapted to the Developing World, ICARDA-derived lines and cultivated landraces were pre-selected to form the CBBT. Using the Mean of Transformed Kinships method, we assembled a panel capturing most of the allelic diversity in the GBP. The CBBT (N=250) preserves good balance between row-types and good representation of both phenology allelic combinations and subpopulations of the GBP. The CBBT and its genotypic data is available to researchers worldwide as a collaborative tool to underpin the genetic mechanisms of traits of interest for barley cultivation.

Utilization of Grain Physical and Biochemical Traits to Predict Malting Quality of Barley (Hordeum vulgare L.) under Sub-Tropical Climate.

Barley is the most popular raw material for malting, and recently, the demand for malt-based products has increased several folds in India and other South Asian countries. The barley growing season is peculiar in the sub-tropical plains region compared to European or Northern American conditions, characterized by a total crop duration of 130-145 days with a maximum grain filling duration of around only 35-40 days. A total of 19 barley genotypes were grown for three years to assess the comparative performance in relation to different quality traits, including grain physical traits and biochemical and malt quality parameters. Analysis of variance, Pearson correlation, and principal component analysis were performed to determine the correlation among different traits. The results showed significant genotypic variation among genotypes for individual grain and malt traits. Despite the shorter window for grain filling, several good malting genotypes have been developed for the sub-tropical climates. The genotypes DWRUB52, DWRB101, RD2849, DWRUB64, and DWRB91 were found suitable for malting. Based on correlation studies, a few grain parameters have been identified which can be used to predict the malting potential of a barley genotype. The hot water extract was found to be positively correlated with the grain test weight, thousand-grain weight, and malt friability but was negatively correlated with the husk content. Beta-glucan content varied from 3.4 to 6.1% (dwb); reducing the grain beta-glucan content and increasing the amylase could be priorities to address in future malt barley improvement programs under sub-tropical climatic conditions.

Prevalence of anemia among toddlers (12-36 months) in urban area of district Rohtak, Haryana.

Background: Children are considered as an important asset for any country and their health as one of the important indicators of a healthy country. There are several factors affecting children's health and anemia is one of them. Globally around 1.62 billion people are affected by it, which corresponds to 24.8% of the population, with the highest prevalence of anemia (47.4%) among preschool-aged children. Aim: The present study was conducted to estimate the prevalence of anemia among toddlers (12-36 months) and to determine the associated factors. Materials and Methods: A cross-sectional study was carried out among toddlers (12-36 months) in the urban field practice area of Pt. B.D. Sharma PGIMS, Rohtak. A total of 170 toddlers were enrolled in the study and their mothers were interviewed using a semi-structured pretested questionnaire. Hb was estimated by Sahli's acid hematin method. The data were analyzed using SPSS software version 20. Results: In the present study, more than half (55.9%) participants were girls and 44.1% were boys. The overall prevalence of anemia was found to be 62.4%, with mild, moderate, and severe anemia being 41.8%, 17.7%, and 2.9%, respectively. The children with regular intake of iron supplementation were found to be 6.625 times likely to be nonanemic as compared to those with no supplementation. Conclusion: Every endeavor should be made to combat the anemia in children through multisectoral and multipronged approach such as nutritional education of mothers, growth monitoring, nutritional supplementation, etc.

To study the knowledge about the handling of biomedical waste among health-care workers in a COVID-19 hospital setting.

BACKGROUND: The unexpected increase in COVID-19-related waste and its inappropriate disposal had blown up the threat of retransmission of this infection and adversely impacted the environment. The aim of this study was to evaluate the existing knowledge about the handling of biomedical waste (BMW) in the COVID-19 Hospital setting among health-care workers (HCWs). MATERIALS AND METHODS: It was a prospective cross-sectional study done for 3 months, i.e., October 2020-December 2020 among nursing professionals across all seniority posted in COVID hospital. A pretested questionnaire comprised 20 questions was used as a study tool. RESULTS: The response rate of our study was 94%. The mean age of respondents was 33.97 years, and the mean length of service was 8.32 years. The study revealed that the respondents had a mean knowledge score of 12.21 (Median 12, standard deviation 2.129 and 95% confidence interval of 11.92-12.51). CONCLUSIONS: There is consensus among the researchers/scholars that COVID-BMW hazards are much more significant than regular BMW. Therefore, its awareness among the HCWs can be a panacea for safer handling of BMW generated in COVID Hospital.

Cost of National Vector Borne Disease Control Programme in North India.

Background & objectives: Despite significant resources being spent on National Vector Borne Disease Control Programme (NVBDCP), there are meagre published data on health system cost upon its implementation. Hence, the present study estimated the annual and unit cost of different services delivered under NVBDCP in North India. Methodology: Economic cost of implementing NVBDCP was estimated based on data collected from three North Indian States, i.e. Punjab, Haryana and Himachal Pradesh. Multistage stratified random sampling was used for selecting health facilities across each level [i.e. subcentres (SCs), Primary Health Centres (PHCs), community health centres (CHCs) and district malaria office (DMO)] from the selected States. Data on annual consumption of both capital and recurrent resources were assessed from each of the selected facilities following bottom-up costing approach. Capital items (equipment, vehicles and furniture) were annualized over average life span using a discount rate of 3 per cent. The mean annual cost of implementation of NVBDCP was estimated for each level along with unit cost. Results: The mean annual cost of implementing NVBDCP at the level of SC, PHC and CHC and DMO was ₹ 230,420 (199,523-264,901), 686,962 (482,637-886,313), 1.2 million (0.9-1.5 million) and 9.1 million (4.6-13.5 million), respectively. Per capita cost for the provision of complete package of services under NVBDCP was ₹ 45 (37-54), 48 (29-73), 10 (6-14) and 47 (31-62) at the level of SC, PHC, CHC and DMO level, respectively. The per capita cost was higher in Himachal Pradesh (HP) at SC [₹ 69 (52-85)] and CHC [₹ 20.8 (20.7-20.8)] level and in Punjab at PHC level [₹ 89 (49-132)] as compared to other States. Interpretation & conclusions: The evidence on cost of NVBDCP can be used to undertake future economic evaluations which could serve as a basis for allocating resources efficiently, policy development as well as future planning for scale up of services.

Association of psychosocial factors with aggression among school going rural adolescents in Haryana.

BACKGROUND: Adolescents are being involved in aggressive activities nowadays. Sometimes, involvement in aggressive activities may be fatal for the victim as well as for the doer. It is a matter of great concern for all including parents, teachers, psychologists, social reformers, and others. A momentary expression of anger sometimes may spoil the future life of the adolescents. AIM AND OBJECTIVES: To determine the prevalence of aggression and to identify the psychosocial risk factors associated with aggression among school-going adolescents. METHODOLOGY: The study recruited 480 school-going rural adolescents from eight government senior secondary schools in the rural block of Beri, district Jhajjar (Haryana). OBSERVATIONS: The mean age of the adolescents was 14.11 ± 1.12 years; 49.4% of the adolescents were found to be aggressive. After applying binary logistic regression, there was a statistically significant relation between aggression and determinants like class, gender, occupation of the father. CONCLUSION AND RECOMMENDATIONS: The study concluded that determinants like age, class of students, gender of the subject, occupation of father found a significant association with aggression. To solve this current situation, parents must give love, attention to their children and must act in an appropriate way in front of them and be role models.

Assessment and modeling using machine learning of resistance to scald (Rhynchosporium commune) in two specific barley genetic resources subsets.

Barley production worldwide is limited by several abiotic and biotic stresses and breeding of highly productive and adapted varieties is key to overcome these challenges. Leaf scald, caused by Rhynchosporium commune is a major disease of barley that requires the identification of novel sources of resistance. In this study two subsets of genebank accessions were used: one extracted from the Reference set developed within the Generation Challenge Program (GCP) with 191 accessions, and the other with 101 accessions selected using the filtering approach of the Focused Identification of Germplasm Strategy (FIGS). These subsets were evaluated for resistance to scald at the seedling stage under controlled conditions using two Moroccan isolates, and at the adult plant stage in Ethiopia and Morocco. The results showed that both GCP and FIGS subsets were able to identify sources of resistance to leaf scald at both plant growth stages. In addition, the test of independence and goodness of fit showed that FIGS filtering approach was able to capture higher percentages of resistant accessions compared to GCP subset at the seedling stage against two Moroccan scald isolates, and at the adult plant stage against four field populations of Morocco and Ethiopia, with the exception of Holetta nursery 2017. Furthermore, four machine learning models were tuned on training sets to predict scald reactions on the test sets based on diverse metrics (accuracy, specificity, and Kappa). All models efficiently identified resistant accessions with specificities higher than 0.88 but showed different performances between isolates at the seedling and to field populations at the adult plant stage. The findings of our study will help in fine-tuning FIGS approach using machine learning for the selection of best-bet subsets for resistance to scald disease from the large number of genebank accessions.

Association between the socioeconomic determinants and soil-transmitted helminthiasis among school-going children in a rural area of Haryana.

BACKGROUND: WHO indicates that India has the highest burden of soil-transmitted helminthiasis (STH) in the world, contributing to 25% of the total global cases, with 220 million children aged 1-14 estimated to be at risk. AIM AND OBJECTIVE: To study the association between the socioeconomic factors and STHs among primary school children in a rural area of Haryana. METHODOLOGY: The study was conducted among children aged 6-10 years studying in the rural government primary schools in the rural areas of Haryana. A total of 300 children were enrolled from government school. RESULTS: The study found that the prevalence of helminthiasis was 28.7% (86/300) and of these 14.0% children were infected with Ascaris lumbricoides and sex wise association with Helminthic infection was observed as statistically nonsignificant. One third of the (31.39%; 27/86) children were pallor and 5.81% subjects were having Bitot's spot while 13.95% children were having constitutional symptoms such as weakness, 6.97% subjects have fatigue, and 5.81% children have body ache. DISCUSSION: The morbidity can be reduced with appropriate inputs to improve the environmental factors. This may need investment for sanitary latrines, food hygiene, and safe drinking water, anti-helminthic drugs, and health education. CONCLUSION AND RECOMMENDATIONS: The results of the study concluded and recommended that proper implementation of national deworming day and other long-term strategies like sanitation, clean drinking water, adequate sanitation, and also improvement in nutritional status through various nutritional health programmes.

Design, synthesis and neuropharmacological evaluation of new 2,4-disubstituted-1,5-benzodiazepines as CNS active agents.

Benzodiazepines (BZDs) represent a class of privilege scaffold in the modern era of medicinal chemistry as CNS active agents and BZD based drugs are used to treat different psychotic disorders. Inspired from the therapeutic potential of BZDs as promising CNS active agents, in the present work three different series of 1,5-benzodiazepines bearing various substitutions at position 2 and 4 of the benzodiazepine core were synthesized by condensing different substituted chalcones with o-phenylenediamine in the presence of piperidine as a base catalyst. Structural characterization of title compounds was done by using various analytical techniques such as IR, NMR, elemental analysis and mass spectral data. All the synthesized compounds (9a-d, 10a-e and 11a-c) were subjected to in vivo neuropharmacological studies to evaluate their CNS depressant and antiepileptic activity. Results of in vivo evaluation data showed that analogue 11b exhibited potent CNS depressant activity which was comparable to the standard drug diazepam. Compounds 10b and 10c displayed significant antiepileptic activity however they were less potent than the standard drug phenobarbitone. Molecular docking studies were performed using MOE software to find the interaction pattern and binding mode at the GABAA receptor (PDB Id: 6HUP). The results of the docking studies were in good agreement with the observed in vivo activity and revealed the satisfactory binding mode of the compounds within the binding site of the protein. The docking scores for the most promising candidates 10c, 11b and Diazepam were found to be -9.18, -9.46 and -9.88, respectively. Further, the compounds showed compliance with the Lipinski's 'rule of five' and exhibited favourable drug-likeness scores. The identified leads can be explored further for the design and development of new BZD based psychotropic agents.

Genome Wide Association Mapping of Spot Blotch Resistance at Seedling and Adult Plant Stages in Barley.

Barley spot blotch (SB) caused by Cochliobolus sativus is one of the major constrains to barley production in warmer regions worldwide. The study was undertaken to identify and estimate effects of loci underlying quantitative resistance to SB at the seedling and adult plant stages. A panel of 261 high input (HI-AM) barley genotypes consisting of released cultivars, advanced breeding lines, and landraces, was screened for resistance to SB. The seedling resistance screening was conducted using two virulent isolates from Morocco (ICSB3 and SB54) while the adult plant stage resistance was evaluated at two hot spot locations, Faizabad and Varanasi, in India under artificial inoculation using a mixture of prevalent virulent isolates. The HI-AM panel was genotyped using DArT-Seq high-throughput genotyping platform. Genome wide association mapping (GWAM) was conducted using 13,182 PAV and 6,311 SNP markers, for seedling and adult plant resistance. Both GLM and MLM model were employed in TASSEL (v 5.0) using principal component analysis and Kinship Matrix as covariates. Final disease rating and Area Under Disease Progress Curve (AUDPC) were used for the evaluation of adult stage plant resistance. The GWAM analysis indicated 23 QTL at the seedling stage (14 for isolate ICSB3 and 9 for isolate SB54), while 15 QTL were detected at the adult plant stage resistance (6 at Faizabad and 9 at Varanasi) and 5 for AUDPC based resistance at Varanasi. Common QTL at seedling and adult plant stages were found across all barley chromosomes. Seedling stage QTL explained together 73.24% of the variance for seedling resistance to isolate ICSB3 and 49.26% for isolate SB54, whereas, QTL for adult plant stage resistance explained together 38.32%, 44.09% and 26.42% of the variance at Faizabad and Varanasi and AUDPC at Varanasi, respectively. Several QTL identified in this study were also reported in previous studies using bi-parental and association mapping populations, corroborating our results. The promising QTL detected at both stages, once validated, can be used for marker assisted selection (MAS) in SB resistance barley breeding program.

Acute Psychological Stress is a Trigger for Stroke: A Case-Crossover Study.

BACKGROUND: Conventional risk factors for stroke that have been identified are mostly chronic diseases that explain much of the variation as to who develops stroke. However, these risk factors do not equip us with the means to predict when an event like stroke will occur. It has been observed that acute events like stroke and coronary heart disease are preceded by episodes of acute stress. The present study was undertaken to determine whether acute psychological stress is a potential triggering factor for the occurrence of stroke. METHODS: In accordance with the case-crossover study design, patients or Legally Authorized Representative (LAR) were asked to report psychological stress during the two-hour hazard period before the event and during the control period, which was the same 2-hour time period the day before the event. Conditional logistic regression was used to compare each person's exposure during the hazard period to their exposure during the control period. RESULTS: A total of 151 stroke patients were interviewed. Acute psychological stress was associated with transient increased odds of stroke in the subsequent 2 hours that was 3.4 times higher than the odds during periods with no exposure to these triggers (95% confidence interval 1.55-7.50). CONCLUSIONS: Acute psychological stress is a potential independent triggering factor for the occurrence of stroke. Further confirmatory studies are required to help corroborate these findings and elucidate the mechanisms underlying this short-term increase in risk.

Social stigma and its determinants among people living with HIV/AIDS: A cross-sectional study at ART center in North India.

INTRODUCTION: HIV/AIDS-related stigma and discrimination together have long been recognized as one of the main obstacles in the prevention, care, and treatment of HIV and AIDS. Yet, little has been done on a large scale to combat them. Stigma still precludes many in need of treatment and care for people living with HIV/AIDS (PLHIV). The purpose of this study was to assess the social stigma among PLHIV and the factors influencing it. MATERIAL AND METHODS: This hospital-based cross-sectional study was conducted among four hundred PLHIV attending the antiretroviral therapy (ART) center of a tertiary care institute of Haryana, India, using a semi-structured questionnaire and Berger Stigma Scale. Data analysis was performed using SPSS version 20.0 software to explore the relationship between a dependent (social stigma score) and other independent variables. RESULTS: The overall mean stigma score in our study was found to be 110.96 ± 17.05. The stigma score in the male PLHIV was higher than in females. Male gender, younger age group (18-25 years), nuclear family, and rural residents PLHIV experienced more stigma as showed by the logistic regression analysis. CONCLUSION: Stigma and discrimination are a continuous deterrent for program implementation or successful outcomes. Education, behavior change strategies, and building supportive environments to the targeted population (young, single, and rural residents) can provide a roadmap in ending stigma and discrimination.
