Ethnomedicinal plants of the sacred groves and their uses by Karbi tribe in Karbi Anglong district of Assam, Northeast India
277-287The present study was conducted to record the ethnomedicinal plants and their uses by the Karbi tribe in Bichikri and Harlong sacred groves of West Karbi Anglong district of Assam. A prestructured questionnaire survey and quantitative analysis was carried out to record the medicinal plants and to determine the ailments categories. A total of 38 ethnomedicinal plants (36 genera and 27 families) were recorded from the study sites. Leaves were found as the dominant plant parts used for the treatment of various health ailments. The highest Fic value was recorded for cold, dermatological, skeletal muscle pain and inflammation, general health, and infectious disease and genital-urinary disorder categories. The informant agreement ratio (IAR) was found higher for 18 species. The fidelity level (FL) of 11 species secured the highest FL value (100%) and the used value (UV) was in the range of 0.05 to 0.93. The present study has revealed that the Karbi tribe living around the sacred groves depends on the plant species for their health care. However, proper management is required for the conservation of sacred groves through sustainable utilization of medicinal plants occurred in the groves
Management of a case of thromboembolism post spine surgery: a case report
Postoperative deep vein thrombosis (DVT) of lower limbs is often asymptomatic. In many patients, fatal pulmonary embolism (PE) is the first clinical manifestation of postoperative venous thromboembolism (VTE). Routine screening for asymptomatic DVT of the lower limbs has a low sensitivity and is quite impractical. For these reasons, routine and systematic prophylaxis in patients at risk, is the strategy of choice to reduce the burden of VTE after surgery. If used appropriately such prophylaxis is cost effective since it reduces the incidence of symptomatic thromboembolic events, which require costly diagnostic procedures and prolonged anticoagulation therapy. Here we report the post-operative course of a spine surgery patient, presenting with DVT in calf veins, which lodged into pulmonary artery and was managed successfully with low molecular weight heparin (LMWH), embolectomy, inferior vena cava (IVC) filter, and dabigatran
Rocket Sled Based High Speed Rail Track Test Facilities
The present study introduces and compares several high-speed track based ground test facilities available all over the world to simulate high-speed dynamic events for selected portions of flight trajectories. The scope of performing high speed flight-testing is addressed, which is followed by the requirements of these track based test facilities. The facilities deliver flight test articles under controlled conditions to achieve high velocity impact, acceleration, aerodynamic and other related testing for small and large test articles depending upon the requirements. Sled is designed in such a way so that it can carry the test articles like aircrafts, payloads, warheads, missiles and many other ballistic systems to achieve high velocities ranging from subsonic to hypersonic by accelerating these sleds using solid rocket motors over the rail track. Such facilities provide instrumentation for large set of trial data acquisition and offline analysis for both recovery and non- recovery (impact) trials, which makes such facilities important for test, research and evaluation purposes.
Here, the detailed description of test facilities, which are available in many countries such as India, United States (US), Japan, United Kingdom (UK), France, and others countries based on their technical characteristics is presented. Additionally, a brief history and introduction into basic rocket sled test facility aspects, essential technical characteristics and major features to support high speed testing at these facilities as an accurate testing technique based on quality of construction and engineering design are also covered in this paper. Compilation of available or under development facilities is done in one place which provides the information about facilities’ technological gaps. The paper concludes with an explanation of the role, major capabilities and limitations of these test facilities in the present global scenario
Association of FADS2 rs174575 gene polymorphism and insulin resistance in type 2 diabetes mellitus
Background: Many risk factors contribute to the pathogenesis of
diabetes. Gene and lifestyle factors are considered to be the major
contributors. A dietary pattern is attributed to be one of the
lifestyle risk factors favoring diabetes. The present study aims to
find an association between fatty acid desaturase (FADS) gene
polymorphism and glycemic profile in type 2 diabetes mellitus (T2DM).
Methodology: A total of 429 subjects were included in the study on the
basis of inclusion and exclusion criteria, of which 213 and 216
subjects were diabetic and control, respectively. Body mass index was
calculated. Fasting plasma glucose, glycated hemoglobin (HbA1c) and
insulin were measured using commercially available kits. rs174575 of
FADS2 was selected based on previous publications and identified using
the dbSNP database. To compare the biochemical parameters with the
genotype, the following three models were used: additive model (CC vs
CG vs GG), dominant model (CC + CG vs GG), and recessive model (CC vs
CG + GG). Results and Discussion: FBS, HbA1c, insulin, HOMA-IR, and
HOMA-B exhibited a high and statistically significant difference
between subjects and controls. The three models exhibited a
statistically significant difference between FBS, HOMA-IR, and HOMA- B
(p<0.05). Conclusion: The distribution of rs174575 genotype differed
significantly between the subjects and controls in the present study.
The study revealed that genetic variation in FADS2 is an additional
facet to consider while studying the risk factors of T2DM
Protocol update for a randomised controlled feasibility trial of exercise rehabilitation for people with postural tachycardia syndrome:the PULSE study
Background: The PULSE (PostUraL tachycardia Syndrome Exercise) study is a randomised controlled trial assessing the feasibility of conducting a multicentre RCT testing supervised exercise rehabilitation with behavioural and motivational support, compared to best-practice usual care, for people with Postural Tachycardia Syndrome (PoTS). The original trial protocol was published in BMC Pilot & Feasibility Studies (accessible at https://doi.org/10.1186/s40814-020-00702-1). The PULSE intervention consists of (1) individual assessment; (2) 12-week, twice-weekly, supervised exercise training; (3) behavioural and motivational support; and (4) guided lifestyle physical activity. The control intervention is best-practice usual care with a single 30-min, one-to-one practitioner appointment, and general advice on safe and effective physical activity. Sixty-two people (aged 18–60 years) with a confirmed diagnosis of PoTS will be invited to enrol on a feasibility RCT with an embedded qualitative study. The primary outcome will be feasibility; process-related measures will include eligibility, recruitment, randomisation and withdrawal rates, along with indicators of exercise programme adherence and acceptability. Secondary physiological, clinical and health-related outcomes will be assessed. In response to the COVID-19 pandemic, here we describe amendments to the trial protocol. Methods: Restrictions imposed by the COVID-19 pandemic meant it was necessary to change the delivery of the PULSE and control interventions. These changes reflected the need to limit the risk of COVID-19 transmission in a clinical population, some of whom were at increased risk of contracting the virus and suffering serious illness. The major change was that the originally intended centre-based PULSE and control interventions would now be delivered remotely on-line. Subsequently, there were minor changes to the participant eligibility criteria. These decisions followed an on-line co-creation session with people affected by PoTS, and relevant public and professional stakeholders. Conclusions: We present an update of the original trial protocol in response to the COVID-19 pandemic. No participants were recruited to the original protocol; thus, results will reflect the on-line delivery of the intervention. PULSE will be the first randomised trial to assess the feasibility of conducting a definitive multi-centre RCT testing supervised on-line exercise rehabilitation with behavioural and motivational support, compared to best-practice usual care, for people with PoTS.

Establishment of reference CD4+ T cell values for adult Indian population
<p>Abstract</p> <p>Background</p> <p>CD4+ T lymphocyte counts are the most important indicator of disease progression and success of antiretroviral treatment in HIV infection in resource limited settings. The nationwide reference range of CD4+ T lymphocytes was not available in India. This study was conducted to determine reference values of absolute CD4+ T cell counts and percentages for adult Indian population.</p> <p>Methods</p> <p>A multicentric study was conducted involving eight sites across the country. A total of 1206 (approximately 150 per/centre) healthy participants were enrolled in the study. The ratio of male (N = 645) to female (N = 561) of 1.14:1. The healthy status of the participants was assessed by a pre-decided questionnaire. At all centers the CD4+ T cell count, percentages and absolute CD3+ T cell count and percentages were estimated using a single platform strategy and lyse no wash technique. The data was analyzed using the Statistical Package for the Social Scientist (SPSS), version 15) and Prism software version 5.</p> <p>Results</p> <p>The absolute CD4+ T cell counts and percentages in female participants were significantly higher than the values obtained in male participants indicating the true difference in the CD4+ T cell subsets. The reference range for absolute CD4 count for Indian male population was 381-1565 cells/μL and for female population was 447-1846 cells/μL. The reference range for CD4% was 25-49% for male and 27-54% for female population. The reference values for CD3 counts were 776-2785 cells/μL for Indian male population and 826-2997 cells/μL for female population.</p> <p>Conclusion</p> <p>The study used stringent procedures for controlling the technical variation in the CD4 counts across the sites and thus could establish the robust national reference ranges for CD4 counts and percentages. These ranges will be helpful in staging the disease progression and monitoring antiretroviral therapy in HIV infection in India.</p

Identification of a major QTL, Parth6.1 associated with parthenocarpic fruit development in slicing cucumber genotype, Pusa Parthenocarpic Cucumber-6
Parthenocarpy is an extremely important trait that revolutionized the worldwide cultivation of cucumber under protected conditions. Pusa Parthenocarpic Cucumber-6 (PPC-6) is one of the important commercially cultivated varieties under protected conditions in India. Understanding the genetics of parthenocarpy, molecular mapping and the development of molecular markers closely associated with the trait will facilitate the introgression of parthenocarpic traits into non-conventional germplasm and elite varieties. The F1, F2 and back-crosses progenies with a non-parthenocarpic genotype, Pusa Uday indicated a single incomplete dominant gene controlling parthenocarpy in PPC-6. QTL-seq comprising of the early parthenocarpy and non-parthenocarpic bulks along with the parental lines identified two major genomic regions, one each in chromosome 3 and chromosome 6 spanning over a region of 2.7 Mb and 7.8 Mb, respectively. Conventional mapping using F2:3 population also identified two QTLs, Parth6.1 and Parth6.2 in chromosome 6 which indicated the presence of a major effect QTL in chromosome 6 determining parthenocarpy in PPC-6. The flanking markers, SSR01148 and SSR 01012 for Parth6.1 locus and SSR10476 and SSR 19174 for Parth6.2 locus were identified and can be used for introgression of parthenocarpy through the marker-assisted back-crossing programme. Functional annotation of the QTL-region identified two major genes, Csa_6G396640 and Csa_6G405890 designated as probable indole-3-pyruvate monooxygenase YUCCA11 and Auxin response factor 16, respectively associated with auxin biosynthesis as potential candidate genes. Csa_6G396640 showed only one insertion at position 2179 in the non-parthenocarpic parent. In the case of Csa_6G405890, more variations were observed between the two parents in the form of SNPs and InDels. The study provides insight about genomic regions, closely associated markers and possible candidate genes associated with parthenocarpy in PPC-6 which will be instrumental for functional genomics study and better understanding of parthenocarpy in cucumber
Robust estimation of bacterial cell count from optical density
Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data
