Abstract Aim: To evaluate the antifertility effect ofAlstonia scholaris bark extract in male rats. Methods: In male Wistar rats Alstonia scholaris bark extract was given by oral route at a dose of 200 mg/day for 60 days. The fertility and testicular function were assessed by mating tests, sperm motility, sperm concentration, biochemical indices and testicular cell population dynamics. Results: Oral feeding with the extract at a dose of 200 mg/day for the period of 60 days did not cause body weight loss, while the weights of testes, epididymides, seminal vesicle and ventral prostate were significantly reduced. The production of step-19 spermatids was reduced by 79.6% in treated rats. The population of preleptotene and pachytene spermatocytes were decreased by 61.9% and 60.1%, respectively. Spermatogonia and Sertoli cell population were also affected. The seminiferous tubule and Leydig cell nuclear area were reduced significantly (Pcompared to the controls. Reduced sperm count and motility resulted in a total suppression of fertility. A significant fall in the protein and sialic acid content of the testes, epididymides, seminal vesicle and ventral prostate as well as glycogen content of testes were also noticed. The fructose content in the seminal vesicle was lowered whereas the testicular cholesterol was elevated as compared with the controls. The following compounds were obtained from the extract with chromatographic separation over Si-gel column: α-amyrin, β-amyrin, lupiol acetate, venenative, rhazine and yohimbine. conclusion: At the dose level employed, Alstonia scholaris bark extract has a significant antifertility effect in male rats; the primary site of action may be post meiotic germ cells (Step 19 spermatids).

Particuology 2024年第7期90卷 189-198页

作者： Bina Gidwani Vishal Jain Veenu joshi Ravindra Kumar Pandey Shiv Shankar Shukla Amber Vyas columbia Institute of Pharmacy Raipur(C.G.)India University Institute of Pharmacy Pt Ravishankar Shukla UniversityRaipur(C.G.)India center for Basic Science and Research Pt Ravishankar Shukla UniversityRaipur(C.G.)India

Simvastatin, a BcS class II drug, is associated with poor aqueous solubility, first-pass metabolism and short half-life. In the present work, nanoparticles were prepared and evaluated. Optimization of formulation and process parameters was done through the use of independent and dependent variables. Preliminary studies were done to determine suitable range of the concentration of Eudragit polymer (10%–30%) and the ratio of drug to polymer (1:1 to 1:5) for the formation of nanoparticles by emulsification and a solvent evaporation technique. Results revealed that the mean size of nanoparticles was affected by stirring speed from 5000 RPM, 8000 RPM, and 12000 RPM. The results of increase in association efficiency and percent yield with increase in amount of drug from 100 mg, 150 mg, and 200 mg in selected range were observed. In-vitro release studies showed that two formulations possess highest initial burst and slow sustained drug release. There was 2.93-fold decrease in total cholesterol and 3.27-fold increases in triglyceride level during in-vivo study.

Background Tuberculosis (TB) remains a major public health problem in Nepal, high in settings marked by prevalent gender and social inequities. Various social stratifiers intersect, either privileging or oppressing individuals based on their characteristics and contexts, thereby increasing risks, vulnerabilities and marganilisation associated with TB. This study aimed to assess the inclusiveness of gender and other social stratifiers in key health related national policies and the Health Management Information System (HMIS) of National Tuberculosis Programme (NTP) by.c.nducting an intersectional analysis of TB cases recorded via *** A desk review of key policies and the NTP’s HMIS was conducted. Retrospective intersectional analysis utilized two secondary data sources: annual NTP report (2017–2021) and records of 628 TB cases via HMIS 6.5 from two TB centres (2017/18–2018/19). chi-square test and multi-variate analysis was used to assess the association between social stratifers and types of TB, registration category and treatment *** Gender, social inclusion and concept of intersectionality are incorporated into various health policies and strategies but lack effective implementation. NTP has initiated the collection of age, sex, ethnicity and location data since 2014/15 through the HMIS. However, only age and sex disaggregated data are routinely reported, leaving recorded social stratifiers of TB patients static without analysis and dissemination. Furthermore, findings from the intersectional analysis using TB secondary data, showed that male more than 25 years exhibited higher odds [adjusted odds ratio (aOR) = 4.95, 95% confidence interval (cI): 1.60–19.06,P = 0.01)] of successful outcome compared to male TB patients less than 25 years. Similarly, sex was significantly associated with types of TB (P cantly associated with patient registration category (old/new cases).conclusio

It is well known that Diabetes Specific Nutritional Supplements (DSNSs) are linked to improved glycemic control in individuals with diabetes. However, data on efficacy of DSNSs in prediabetics is limited. This was a two-armed, open-labelled, randomized controlled six-week study on 199 prediabetics [30 - 65 years;Glycosylated Hemoglobin (HbA1c) 5.7% - 6.4% and/or Fasting Blood Glucose (FBG) 100-125 mg/dl]. Two parallel phases were conducted: Acute Blood Glucose Response (ABGR) and Intervention phase. Prediabetic participants were randomized into test (n = 100) and control (n = 99). The primary objective was to assess the ABGR of DSNS versus an isocaloric snack, measured by incremental Area under the curve (iAUc). Test and control received 60 g of DSNS and 56 g of isocaloric snack (cornflakes) respectively, both in 250 ml double-toned milk on visit days 1, 15, 29 and 43. Postprandial Blood Glucose (PPG) was estimated at 30, 60, 90, 120, 150 and 180 minutes. During the 4 weeks intervention phase, the test group received DSNS with lifestyle counselling (DSNS + Lc) and was compared with the control receiving lifestyle counselling alone (Lc alone). Impact was studied on FBG, HbA1c, anthropometry, body.c.mposition, blood pressure, nutrient intake, and physical activity. The impact of DSNS was also studied using cGM between two 14-day phases: cGM1 baseline (days 1 - 14) and cGM2 endline (days 28 - 42). DSNS showed significantly lower PPG versus isocaloric snack at 30 (p 12, and chromium were reported by DSNS + Lc versus Lc alone. No other significant changes were reported between groups. It may be concluded that DSNS may be considered as a snack for prediabetic or hyperglycemic individuals requiring nutritional support for improved glycemic control.

AIM： To describe the prevalence of transfusiontransmitted virus （TTV） infection in association with hepatitis A-E viral infections in different forms of liver diseases in North India. METHODS： Sera from a total number of 137 patients, including 37 patients with acute viral hepatitis （AVH）, 37 patients with chronic viral hepatitis （cVH）, 31 patients with cirrhosis of liver and 32 patients with fulminant hepatic failure （FHF）, were analyzed both for TTV-DNA and hepatitis A-E viral markers. Presence of hepatitis B virus （HBV）, hepatitis c virus （HcV） and hepatitis E virus （HEV） infections was detected in different proportions in different groups. Moreover, rrV-DNA was simultaneously tested in 100 healthy blood donors also. RESULTS： None of the patients had hepatitis A virus （HAV） and hepatitis D virus （HDV） infections. Overall prevalence of TTV-DNA was detected in 27.1% cases with AVH, 18.9% cases with cVH, 48.4% cases with cirrhosis and 9.4% cases with FHF. TTV-DNA simultaneously tested in 100 healthy blood donors showed 27% positivity. On establishing a relation between TTV infection with other hepatitis viral infections, TTV demonstrated co-infection with HBV, HcV and HEV in these disease groups. correlation of TTV with ALT level in sera did not demonstrate high ALT level in TTV-infected patients, suggesting that TI-V does not cause severe liver damage. cONcLUSION： TTV infection is prevalent both in patients and healthy individuals in India. However, it does not have any significant correlation with other hepatitis viral infections, nor does it produce an evidence of severe liver damage in patients with liver diseases.

With increasing incidence of diabetes, use of diabetes specific nutrition supplements (DSNS) is common for better management of the disease. To study effect of 12-week DSNS supplementation on glycemic markers, anthropometry, lipid profile, ScFAs, and gut microbiome in individuals with diabetes. Markers studied were glycemic [Fasting Blood Glucose (FBG), Post Prandial Glucose (PPG), HbA1c, Incremental Area under curve (iAUc), Mean Amplitude of Glycemic Excursions (MAGE), Time in/above Range (TIR/TAR)], anthropometry [weight, Body Mass Index (BMI), waist circumference (Wc)], lipid profile, diet and gut health [plasma short chain fatty acids (ScFAs)]. N = 210 adults were randomized to receive either DSNS with standard care (DSNS + Sc;n = 105) or standard care alone (Sc alone;n = 105). After 12 weeks, significant differences between DSNS + Sc versus Sc alone was observed in FBG [−3 ± 6 vs 14 ± 6 mg/dl;p = 0.03], PPG [−35 ± 9 vs −3 ± 9 mg/dl;p = 0.01], weight [−0.6 ± 0.1 vs 0.2 ± 0.1 kg;p = 0.0001], BMI [−0.3 ± 0.1 vs 0.1 ± 0.1 kg/m2;p = 0.0001] and Wc [−0.3 ± 0.2 vs 0.2 ± 0.2 cm;p = 0.01]. HbA1c and low-density lipoprotein (LDL) were significantly reduced in DSNS + Sc [−0.2 ± 0.9;p = 0.04 and −5 mg/dl;p = 0.03] respectively with no change in control. continuous Glucose Monitoring (cGM) reported significant differences between DSNS + Sc versus Sc alone for mean glucose [−12 ± 65 vs 28 ± 93 mg/dl;p c [−192 (1.1) vs −48 (1.1) mg/dl;p = 0.03]. MAGE was significantly reduced for both DSNS + Sc (−19 ± 67;p c alone (−8 ± 70;p = 0.04), with reduction being more pronounced for DSNS + Sc. DSNS + Sc reported a decrease in carbohydrate energy % [−9.4 (−11.3, −7.6) %;p creased dietary fiber [9.5 (7.2, 11.8) g;p y % [0.9 (0.5, 1.3) %;p c alone. DSNS + Sc reported signi

Research in Astronomy and Astrophysics 2017年第11期17卷 59-70页

作者： yogesh chandra joshi Rukmini Jagirdar Aryabhatta Research Institute of Observational Sciences Manora Peak Nainital 263002 India center for Advanced Study in Astronomy Osmania University 500007 India

We carry out a re-analysis of the photometric data in Rclc bands which were taken during the Nainital Microlensing Survey from 1998 to 2002 with the aim to detect gravitational microlensing events in the direction of M31. Here, we do photometric analysis of a faint W UMa binary.c.S_JO04259.3＋410629 identified in the target field. The orbital period of this star is found to be 0.266402±0.000018 d. The photometric mass ratio, q, is found to be 0.28±0.01. The photometric light curves are investigated using the Wilson-Devinney （WD） code and absolute parameters are determined using empirical relations which provide masses and radii of the binary as M1 = 1.19±0.09M⊙, M2 = 0.33±0.02M⊙ and R1 = 1.02±0.04R⊙, R2 = 0.58±0.08Re respectively based on Rc band data. Quite similar values are found by analyzing/c band data. From the photometric light curve examination, the star is understood to be a low mass-ratio overcontact binary of A-subtype with a high fill-out factor of about 47%. The binary system is found to be located approximately at a distance of 2.64±0.03 kpc having a separation of 2.01 ±0.05 Re between the two components.

Atomic Processes in Emission characteristics of a Lithium Plasma Plume Formed by Double-Pulse Laser Ablation

引用

Plasma Science and Technology 2013年第3期15卷 204-208页

作者： V.SIVAKUMARAN AJAI KUMAR R.K.SINGH V.PRAHLAD H.c.joshi Institute for Plasma Research

High resolution spectral analysis of lithium plasma formed by single and double laser ablation has been undertaken to understand the plume-laser interaction, especially at the early stages of the plasma plume. In order to identify different atomic processes in evolving plasma, time resolved spectral emission studies at different inter-pulse delays have been performed for ionic and neutral lithium lines emitting from different levels. Along with the enhancement in emission intensity, a large line broadening and spectral shift, especially in the case of excited state transition Li I 610.3 nm have been observed in the presence of the second pulse. This broadening and shift gradually decrease with increasing time delay. Another interesting feature is the appearance of a multi-component structure in the ionic line at 548.4 nm and these components change conversely into a single structure at the later stages of the plasma. The multi-component structures are correlated with the presence of different velocity （temperature） distributions in non-LTE conditions. Atomic analyses by.c.mputing photon emissivity.c.efficients with an ADAS code have been used to identify the above processes.
