Lymphatic Filariasis is one of the most abandoned tropical diseases caused by the parasite, Brugia malayi. The existing conventional drugs act generally on the larval stages of the parasite. The enzyme asparaginyl tRNA synthetase is an excellent molecular target as it plays a crucial role in protein synthesis. Evidences based on the literature presented clues to discover the flavonoids as potential anti-filarial leads, which led to the scope for this computational study. The computational parameters such as docking score, binding energy, intermolecular hydrogen bond interaction and the identical amino acids confirm that flavonoids could serve as prospective anti-filarial agents. The outcomes prove that they can be further explored in in-vitro and in-vivo studies to authenticate their claim as potential anti-filarial...

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...
