Phenol was used as a sole carbon source for the perchlorate biodegradation as reported for the first time. Isolated bacterial species Pseudoxanthomonas sp. isolated from a sewage sludge consortium was found to reduce perchlorate while taking phenol as electron acceptor. The growth and perchlorate degradation were analyzed in a batch system along with the degradation profile of phenol by the microbial culture. The effect of the co-pollutants (nitrate, chlorate, nitrate, phosphate) was also considered as part of the present study, where nitrate was found to be the most significant. Perchlorate was significantly removed by the culture involving subsequent phenol degradation in a continuous packed bed system anaerobically from synthetic...

Bell’s palsy is an idiopathic, unilateral, acute weakness of the face in a pattern consistent with peripheral facial nerve dysfunction and may be partial or complete, occurring with equal frequency on either side of the face. The incidence is about 20 in 100,000 people a year, with about 1 in 60-lifetime risks. Bell’s palsy has a peak incidence between the ages of 15 and 40 years. Viral infections are commonly associated with facial nerve pathology, which leads to peripheral facial paralysis. A potential cause of peripheral facial paralysis might be COVID-19 and neurological symptoms could be the first and only manifestation of the disease. Possible mechanisms related to nerve damage in idiopathic facial nerve paralysis include ischemia of vasa nervorum and demyelination induced by an inflammatory process. Direct viral damage or an autoimmune reaction toward the nerve-producing inflammation would be alternative or contributing mechanisms to dysfunction. Acyclovir (aciclovir) is a nucleoside analogue antiviral drug active against some of the herpes virus groups of DNA viruses and RNA viruses. The...

Background: Pomalidomide belongs to BCS class IV drug with low solubility and undergoes first-pass metabolism leads to reduced bioavailability of 15%. Objective: The current study aimed to develop pomalidomide Super saturable-SNEDDS to enhance solubility. Methods: Preliminary solubility studies were performed to identify oil, surfactant, and co-surfactant ratios. Pseudo tertiary phase diagram constructed to select the areas of nanoemulsion and based on monophasic region. Nineteen ratios were selected for drug loading study having oil: Smix ratio in 3:1, from which 15 formulations of pomalidomide SNEDDS were prepared with 4mg drug loading and screened for visual observation and turbidity measurement studies. These SNEDDS are further characterized for robustness, content of drug, entrapment efficiency, and in-vitro dissolution analysis. The optimized SNEDDS formulation was selected for screening of precipitation inhibitor by adding 2% precipitation inhibitors, and concentration-time profiles were studied under non-sink conditions from which best PI was selected and then in-vitro dissolution studies conducted for the super saturable SNEDDS (S-SNEDDS). The optimized final formulation S-SNEDDS with the highest drug release was analyzed...

To study the hepatoprotective activity of ethanolic leaves extracts of Abroma augusta against non-alcoholic fatty liver disease to validate ethnobotanical claim regarding the plant used in the above mentioned disease. Materials and Methods: The hepatoprotective potential of Abroma augusta leaves extract (AALE) (250 and 500 mg/kg/ body weight) was studied on Methionine and Choline deficient diet (MCD diet), High Fat Diet (HFD), Cholesterol and Cholate diet (CCD) and streptozotocin + HFD induced non-alcoholic fatty liver disease. In the last treatment, blood was collected from direct cardiac puncture and analyzed for various parameters like alanine aminotransferase (ALT), aspartate transaminase (AST), triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), free fatty acid (FFA) and malondialdehyde (MDA). Results: The present study showed for the first time that AALE reduced level of ALT, AST, TG, TC LDL, FFA, MDA and possessed hepatoprotective activity as evidenced by its significant inhibition in the formation of hepatoxicity induced by diet and chemical agents with maximum curation (500mg/kg/b.w.) against non-alcoholic fatty liver disease. It...

Postoperative atrial fibrillation (POAF) is a frequent rhythm disturbance after cardiac surgery and is associated with poor cardiovascular outcomes. Beta-blocker therapy is an effective strategy to prevent or decrease the high incidence of POAF and β1-adrenergic receptor (β1AR) polymorphisms that affect the cardiac response to β1AR antagonists. The study objective is to analyze the association between genetic variations in the β1AR gene and the risk of POAF and the prophylactic effect of beta-blockers. Totally, 198 patients undergoing first-time cardiac surgery were examined. The patients after operation were grouped as either with POAF or without POAF according to their continuously electrocardiogram monitoring within ICU and hospital admission period. Subsequently, genotype frequencies of the β1AR gene were determined by polymerase chain reaction-restriction fragment length polymorphism. The results showed that 63 patients (31.8%) of the total study population developed POAF. After the application of a multivariate logistic regression model, the incidence of POAF was associated with Arg389Gly genotype (OR=2.48; 95% CI, 1.06-5.76; p=0.036), Arg389Arg genotype (OR=3.38; 95% CI, 1.28-9.33; p=0.018) and Arg389Ser49...
