About 70 middle aged (20 – 45 years) patients, including 40 males and 30 females, operated at Base Military Hospital, Meerut Cantonment Board, Meerut (India) developed typical symptoms of pus formation at surgical sites and opening of sutures after 30 – 45 days. To investigate the causative pathogen and source of infection, various samples were collected from wounds and various sites of Operation Theatre. The samples were processed on culture media including nutrient agar, McConkey agar and Lowenstein-Jensen’s medium (LJ medium). To identify the pathogens, Gram’s and acid fast staining of the smears of samples and cultures obtained on different media, were carried out. Acid fast bacilli were observed after 3 – 5 days of incubation on LJ medium. The wound samples showed the prevalence of Mycobacterium chelonae and acid fast...

A simple, sensitive, and high-performance liquid chromatography ultraviolet detection (HPLC-UV) method was developed and validated for the quantification of palbociclib in human plasma. Plasma samples were processed by solid phase extraction using an Oasis hydrophilic-lipophilic balance extraction cartridge (1 mL, 30 mg). Commercial imatinib was used as an internal standard. Palbociclib and imatinib (IS) in human plasma were analyzed using a mobile phase of acetonitrile and 0.1% Triethylamine TEA (pH 3.3; adjusted with 50% Ortho-phosphoric acid) (70:30, v/v), on a Agilent Zorbax C18 column (150 × 4.6 mm i.d., 5 µm) using isocratic elution at a flow rate of 1.0 mL/min with ultraviolet detection at 266 nm. The method was validated over a concentration range of 0.1-3.0 µg/mL (r2 ≥ 0.998) with coefficient of variation for intraday precision of 3.92%, 3.56% and 2.28% for 0.5, 1.5, and 2.5 µg/mL respectively. The lower limit of detection was 50 ng/mL. The extraction recovery rates for palbociclib ranged from 66.69% to 80.97%. The intra- and inter-day precision was below 5.0%, and the...

Atherosclerosis is a condition where the arteries become narrowed and hardened due to an excessive build up of plaque around the artery wall. The disease disrupts the flow of blood around the body, posing serious cardiovascular complications. Liver X alpha receptor (LXRα) is highly expressed in liver, function as cholesterol sensors with important roles in regulating cholesterol homeostasis. The leaves of Corchorus trilocularis possess anti-atherosclerotic property along with its anti hyperglycemic activity. The Genetic Optimization for Ligand Docking (GOLD) software resulted in identifying the best compound that interacts with the receptor. The present study was carried out to evaluate the anti-atherosclerotic activity of the ethanolic leaf extract of Corchorus trilocularis against LXRα by...

A LC-MS method was developed and validated for determination of ergocalciferol in human plasma. n-hexane was used as extraction solvent while kinetex C18 50*2.1 mm, 1.7µm was used as analytical column for chromatographic separation. Mobile phase was acetonitrile: 0.1% formic acid in methanol (90:10). Turbo ion spray with positive polarity was used as an interface with API QTRAP 5500 LC/MS/MS system. The calibration range was validated for 2.03 ng/mL to 150.69 ng/mL. Limit of quantification was 2.03 ng/mL. The recovery of Analyte was 97.04% to 99.27%. Labeled erythromycin was used as an internal standard for this method. Inter-batch and intra-batch accuracy and precision were calculated to check method’s performance. Stability was established for all anticipated working conditions for analyte as well as internal standard. Apart from stability experiments, other experiments were also performed to simulate the conditions of subject sample analysis. This method was applied successfully on bioequivalence study to evaluate pharmacokinetic...

The present study was conducted to investigate protective effect of hydro-methanolic (2:3) extract of leaf of Abroma augusta in streptozotocin induced diabetic male albino rat. For this purpose animals were divided into three treatment groups (n = 6): control group, STZ induced diabetic group (STZ 4 mg / 0.1 ml citrate buffer/ 100 g body weight), hydro-methanolic extract of leaf of Abroma augusta treated group (20 mg / 0.5 ml distilled water/100 g body weight). Treatment was conducted for 28 days. Blood glucose, serum insulin, glycated haemoglobin levels along with activities of hepatic carbohydrate metabolic enzymes, hexokinase and glucose-6-phosphate dehydrogenase were assed in all experimental groups. Oxidative stress markers like catalase, peroxidase enzyme activities, conjugated diene and thiobarbituric acid reactive substance levels in liver were measured. All these parameters were significantly recovered towards the control level after the treatment of hydro-methanolic extract. Pancreatic islet diameter, count of islet and number of cells in islets also decreased in diabetic animals. Treatment of these animals with extract resulted significant recovery towards...
