Glutathione peroxidase gene expression profiling has been determined using budding yeast, S. cerevisiae, as a model organism mainly used for extensively reliable microbial studies of various cellular processes evolved in evolutionarily distant species. Roots of five medicinal plants were used: Withania somnifera, Terminalia arjuna, Ranunculus sceleratus, Bacopa monnieri and Acalypha indica. The maceration method exhibited the extraction process, followed by S. cerevisiae culturing at 600nm. Classic Trizol method for RNA extraction of yeast cells. Further, evaluation of the quantity and quality of the isolated RNA before the CDNA synthesis, respectively. Polymerase Chain Reaction was performed using specific conditions, having 60OC as GPx primers annealing temperature. Real-Time Polymerase Chain Reaction of samples was performed where Beta-actin primers as a housekeeping gene. High purity of RNA samples was yielded to be in the range of 1.8-2.0. The size of cDNA PCR products was found to be 118bp. The RT-qPCR results showed high over-expression, i.e., fold change unit of GPx gene in all sample extracts compared to the control yeast. Ethanol and...

Benzodiazepines are psychoactive drugs used to treat anxiety, epilepsy, convulsions, and psychiatric and sleeping disorders. These medicinal compounds possess considerable importance in forensic toxicology due to their tranquilizing, hypnotic, and anticonvulsant properties. Thus, identifying and separating these compounds found significance in pharmaceuticals. The high-performance liquid chromatography (HPLC) technique is employed to separate benzodiazepines. The present research article aims to provide a more straightforward and efficient method for separating benzodiazepines. The thin layer chromatography (TLC) technique follows to separate benzodiazepines containing silica gel 60 F254 as a stationary phase. The seven different mobile phases for the separation of benzodiazepines are employed. The combination of Acetone: Toluene: Ethanol: Ammonia (45:45:7:3) is the best solvent system for separating benzodiazepines among the seven chosen solvent...

To observe the effect of Eucommia, Cuscuta, and Drynaria (E.C.D.) extracts in ovariectomized rats and explore the possible mechanisms. Forty-five female Sprague Dawley rats were randomly divided into 5 groups: sham operation group (Sham), ovariectomized group (Model) and ovariectomized rats + treatment group (estradiol valerate of 104.17 mg/kg/day (EV), E.C.D. extracts of 50.08 mg/kg/day (E.C.D.-L), or E.C.D. extracts of 104.17 mg/kg/day (E.C.D.-H), and all the rats were treated by gavage for 8 weeks). Bone metabolism, estrogen index, phosphorus and calcium were compared, and the right femur structural parameters were evaluated by micro-CT. The rat femoral bone specimens were stained using hematoxylin and eosin for pathological examination, and mRNA expression of related genes in bone tissue was detected by real-time quantitative polymerase chain reaction (PCR). We observed E. C. D.-H groups significantly increased serum estrogen levels, and significantly elevated the maximum load and bone mineral density (BMD) levels in bone tissues. EV group and E. C. D.-H groups improved bone metabolism, biomechanical properties, serum phosphorus and calcium indexes. Compared with...

The worldwide epidemic of Coronavirus disease 2019 (COVID-19), caused by a new virus known as severe acute respiratory syndrome (SARS) coronavirus 2, has posed a growing threat to public health (SARS-CoV-2). The only antiviral drug authorized by the FDA for treating adult and pediatric patients hospitalized with a severe disease is remdesivir, which is given intravenously (IV). Although only a few methods for estimating remdesivir in pharmaceutical formulations using high-pressure liquid chromatography (HPLC) have been described, its determination still requires an accurate, precise, quick, and easy analytical methodology. The main goal of this study was to develop and validate a reliable and accurate HPLC method for quantitative estimation of remdesivir in its intravenous dosage formulation. The separation was performed on a C18 (4.6 mm x 150 mm, 5.0 µm) column with a flow rate of 0.7 mL/min and a total run duration of 6 minutes using a simple isocratic mobile phase of acetonitrile and 0.1 percent formic acid. The method was validated for the system suitability, linearity, precision, accuracy,...

Azolla is a fern plant through conducting 27 % of protein content and involves actively in bioremediation. So, this property of this plant is exploited in the production of chelated minerals. In this study, selenium-enriched azolla is evaluated with Japanese quails on the performance of growth and serological parameters. The present study is designed with 525 quails divided into 7 treatments, each with 3 replicates. Each replicate contains 25 birds. The evaluation was done from day-old chick to 5-week age in a deep litter farming system. The birds in each treatment are distributed in a randomized manner irrespective of gender, later grouped into control, 0.2, 0.3, and 0.4ppm organic selenium treatments, along with 0.2, 0.3, 0.4ppm inorganic selenium treatments sequentially. The body weight gain, feed intake and feed conversion rate were noted every week and significant changes were recorded. In performance trials we observed that 0.2ppm organic selenium shows good performance in body weight gain (P<0.013) and feed conversion rate (P<0.02) at a significant level. At 0.2ppm concentration of...
