Development of a lytic bacteriophage BPK01 impregnated biopolymer (chitosan) hydrogel for combating high-risk strains of carbapenem resistant Klebsiella pneumoniae (CRKP) pathogens- in vitro and in vivo evaluation.

Alternative strategies are urgently required to combat the rise of high-risk carbapenem-resistant Klebsiella pneumoniae (CRKP), including bla-positive strains that produce carbapenemase enzymes, which deactivate beta-lactam antibiotics and result in poor treatment outcomes. In this study, we isolated a bacteriophage BPK01, targeting a high-risk strain of Klebsiella pneumoniae (carbapenem-resistant, bla-positive, ST147, capsular type K64, biofilm former). BPK01 demonstrated strong lytic activity (84%) against a panel of genetically characterized CRKP strains (n = 59) from clinical specimens, including pus, urine, sputum, blood, and tracheal aspirates.

Temperature-Dependent Rotational Dynamics of Non-Polar Solute in Non-Polar Solvents: Influence of Boundary Conditions.

Rotational dynamics of 3-(benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (3BT7D2H-one) non-polar solute in non-polar solvents has been studied by varying temperature to find out how hydrodynamic friction is influenced by solute-size ratio. It has been observed that the rotational dynamics of 3BT7D2H-one follow the Stoke's-Einstein-Debye (SED) model in an n-hexane solvent and it follows the Gierer and Wirtz (GW) model in an n-decane solvent. The probable reason is due to the solute-solvent size ratio which influences boundary conditions parameters and consequently on rotational dynamics of solute.

Triple dip La-Nina, unorthodox circulation and unusual spin in air quality of India.

The recent La-Nina phase of the El Nino Southern Oscillation (ENSO) phenomenon unusually lasted for third consecutive year, has disturbed global weather and linked to Indian monsoon. However, our understanding on the linkages of such changes to regional air quality is poor. We hereby provide a mechanism that beyond just influencing the meteorology, the interactions between the ocean and the atmosphere during the retreating phase of the La-Niña produced secondary results that significantly influenced the normal distribution of air quality over India through disturbed large-scale wind patterns.

The peripheral groups include medial and lateral groups. The central plantar muscles are more numerous and divided into superficial and deep layers.

Evaluation of Probiotic Efficacy of Bacillus subtilis RODK28110C3 Against Pathogenic Aeromonas hydrophila and Edwardsiella tarda Using In Vitro Studies and In Vivo Gnotobiotic Zebrafish Gut Model System.

The indiscriminate use of antibiotics in aquaculture has led to the emergence of resistance; hence, eco-friendly, host-specific alternatives to mitigate bacterial infections have become imminent. In this study, bacteria that could possibly serve as probiotics were isolated and evaluated for their efficacy with in vitro experiments and in vivo zebrafish gut model. One isolate from each of the 23 rohu fish (Labeo rohita) was shortlisted after preliminary screening of several isolates and tested for their ability to inhibit two important warm water bacterial fish pathogens, Aeromonas hydrophila, and Edwardsiella tarda.

Non-alcoholic Fatty Liver Disease in Overt Hypothyroidism: A Cross-Sectional Study in a Tertiary Care Hospital.

Background:  The term non-alcoholic fatty liver disease (NAFLD) describes a condition in which excess fat accumulates in the liver, similar to alcohol-induced liver injury but affecting those who don't consume alcohol. Liver steatosis may vary from simple hepatic steatosis to more serious conditions, including non-alcoholic steatohepatitis and cirrhosis, and is linked to an increased risk of hepatocellular carcinoma (HCC). There is an estimated 20-30% prevalence of non-alcoholic fatty liver disease over the globe.
