Antimicrobial Resistance Surveillance in Human Pathogens in Ahmedabad: A One-Year Prospective Study.

Antimicrobial resistance (AMR) is an escalating global concern, particularly in developing countries like India. A 1-year prospective study was conducted on AMR in human pathogens from Ahmedabad, India. The study aimed to generate an evidence-based database on the AMR profile of pathogens in this region.

Extracting Orientation and Distance-Dependent Interaction Potentials between Proteins in Solutions Using Small-Angle X-ray/Neutron Scattering.

Nonspecific protein-protein interactions (PPIs) are key to understanding the behavior of proteins in solutions. However, experimentally measuring anisotropic PPIs as a function of orientation and distance has been challenging. Here, we propose to measure a new parameter, the generalized second virial coefficient, (), to address this challenge.

Construction of five- and seven-membered rings facilitated by alkyne-azide functionality: access to quinoline fused triazolo-azepines.

The synthesis of novel quinoline-fused triazolo-azepine derivatives has been reported using an intramolecular 1,3-dipolar azide-alkyne cycloaddition strategy. This method possesses considerable potential to synthesize five- and seven-membered rings in high yields (65-87%) without the necessity of metal catalysts or additives. Additionally, this methodology was applicable to pyridine and tetralone based adducts to afford triazolo-azepine derivatives.

Impact of citrate on mitigating iron mediated polysorbate 80 degradation in biotherapeutic formulation placebos.

Polysorbate 80 (PS80), a widely used polymeric surfactant in biotherapeutic formulation, possesses a unique structural composition that effectively prevents protein aggregation in highly concentrated protein drug formulations. However, PS80 is susceptible to hydrolysis, due to the presence of fatty acid esters that can be enzymatically hydrolyzed, The unsaturated bonds in the fatty acids are prone to oxidative degradation when exposed to air, especially in the presence of transition metals such as iron and copper, which may be introduced during production and purification processes or from contamination in raw materials used in drug formulation. The degradation of PS80, particularly through metal-mediated oxidative degradation, poses a significant challenge for the industry.
