Accordingly, a randomised complete block experiment was implemented to assess differences between the three extraction methods, differences between the different sample types, and the interactions between these two factors. Following GC-MS, it was found that there was no significant difference between the results of the steroid extraction methods, regardless of the type of sample used, for the quantity of each steroid extracted. It was concluded that ASE could be used confidently instead of the more established steroid extraction methods, thereby delivering time and cost savings.L-asparaginases are extensively applied in the treatment of Acute Lymphoblastic Leukemia (ALL). The treatment regime of ALL consists of asparaginase from E. coli or Erwinia. The survival rate post-chemotherapy has increased to less then  90% in recent years. Asparaginase therapy has also resulted in numerous toxicities to patients receiving therapy. This study demonstrates the reaction of normal cells of Danio rerio to asparaginase therapy. L-asparaginase I and II used in the present study are from two probiotic Lactobacillus species in comparison with a commercial L-asparaginase of E. coli origin. Zebrafish adults were injected with 2500 U/kg body weight of L-asparaginase treatments. The expression of SOD 2, CAT, GST, GTP BP3, FADS2 were analyzed with EF1α as house-keeping gene. The p value obtained proves that the data are significant. The histology of the L-asparaginase I treated fishes showed dilated sinusoids in the liver and pseudocyst in the pancreas. The L-asparaginase II and commercial asparaginase showed no pathology.Late embryogenesis abundant (LEA) proteins protect organisms from various environmental stresses; however, the underlying mechanism of LEA mediated therapeutic evasion is still unclear in both eukaryotes and prokaryotes. In this study, group 3 LEA protein (G3LEA) of vancomycin-resistant Enterococcus faecium under sublethal concentration of vancomycin stress was evaluated and shown to have two functions the first is the reduction of reactive oxygen species (ROS) content, preventing apoptosis by suppressing apoptotic proteins Cas3 and MAOB, and the second is activating specific drug efflux pumps. Sublethal vancomycin model was established with using Propidium Iodide (PI) stain. Real-time PCR was conducted to evaluate the expression of G3lea. Flow cytometry and confocal microscope using Anti- G3LEA, anti- MAOB, and anti- Cas3 were performed to assess the expression of G3LEA. Under sublethal vancomycin stress, G3LEA is upregulated, suppressing the expression of apoptotic markers and increasing specific efflux markers. These results suggest that G3LEA protein suppresses antibiotic mediated apoptosis in prokaryotic cells and plays a key role in understanding and preventing antibiotic resistance.Keratinous waste is the bulk by-product of various livestock industries. Slow natural degradation of keratin and less efficient chemical hydrolysis imposes challenge for the search of alternative recycling methods. Keratin degrading microbes hydrolyse keratin to soluble peptides and amino acids. Bacillus aerius NSMk2 showed great potential for hydrolysis of chicken feather waste. Bacillus aerius NSMk2 cells grown in phosphate buffer supplemented with chicken feathers showed high disulfide reductase activity and release of sulfhydryl groups. The release of proteins and amino acids were statistically optimized at varied pH (4.0-11.0), temperature (30.0-45.0 °C) and agitation (100-250 rpm), and maximum release was recorded at pH 7.5, temperature 37 °C and shaking (175 rpm). FTIR and SEM showed sulfitolysis and extensive keratinolysis of feathers resulting in complete hydrolysis of white chicken feathers after 84 h. MALDI-TOF mass spectrometry confirmed the release of low molecular weight peptides in the range of 399 to 3289.4 m/z. The present study demonstrates management of otherwise hard-to-degrade keratinous waste and simultaneous nutritional enhancement of waste chicken feathers to value-added hydrolysate that can be used in livestock feed formulations or biofertilizer in agro-industry.The presence of antineoplastic compounds in aquatic ecosystem is an emerging challenge for the society. Antineoplastic compounds released into the aquatic environment exhibit a potential threat to normal aquatic life. Particularly, antineoplastic compounds are responsible for direct or indirect interference with the cellular DNA of an organism and cause toxicity to cells. learn more The present study focused on the assessment of in vitro toxic effect of cyclophosphamide, etoposide and paclitaxel on Raw 264.7 cell line (mouse monocyte macrophage cells). The inhibitory concentration of cyclophosphamide, etoposide, and paclitaxel was determined. The IC50 values of these compounds were 145.44, 5.40, and 69.76 µg ml-1 respectively. This is the first report on toxicity analysis of cyclophosphamide, paclitaxel and etoposide on Raw 264.7 cell line by reducing cell viability and indicating the cell cytotoxicity i.e., 69.58% for cyclophosphamide, 92.01% for etoposide and 88.85% for paclitaxel on concentration 250 µg ml-1. The results of their cytotoxicity assessment highlight the need of improvement in sewage treatment technology for the efficient removal of these compounds from aquatic environment.Trichophyton spp. is one of the main causative agents of dermatophytosis such as tinea ungium and tinea pedis. Resistance to antifungal drugs is a significant clinical problem in dermatophytosis. The main molecular mechanism of antifungal resistance to conventional therapy in dermatophytes is the expression of efflux pumps. Efforts aimed at improving the efficacy of current antifungals such as griseofulvin are relevant. Given this, sesquiterpenes such as α-bisabolol and nerolidol found in essential oils represent promissing alternatives. Griseofulvin sensitivity modulation activity in T. rubrum, T. interdigitale H6, and T. interdigitale Δmdr2 (mutant strain of T. interdigitale) promoted by α-bisabolol and nerolidol were investigated. The minimum inhibitory concentration (MIC) of the test drugs were determined by microdilution. Subsequently, the effect of the drugs tested on plasma membrane functionality (K+ release) was analyzed. The MIC of griseofulvin was determined at sub-inhibitory sesquiterpene concentrations (modulation assay).learn more
