This investigation evaluated the therapeutic benefit of apocynin in isoproterenol (ISO)-induced cardiac damage in rats. ISO-administered male Wistar rats were treated with apocynin for 2 weeks. Blood plasma and left ventricle of heart tissues were collected and analyzed for oxidative stress-related parameters such as malondialdehyde (MDA), advanced oxidation protein product (AOPP), and nitric oxide (NO).

The biologically important thiols (cysteine, homocysteine, N-acetyl cysteine, and glutathione) are key species in redox homeostasis, and there is a clinical need to measure them rapidly, accurately, and simultaneously at low levels in complex biofluids. The solution to the challenge presented here is based on a new derivatizing reagent that combines a thiol-selective unit to optimize the chemical transformation and a precharged pyridinium unit chosen to maximize sensitivity in mass spectrometry. Derivatization is performed simultaneously with ionization ("reactive ionization"), and mass spectrometry is used to record and characterize the thiol reaction products.

The emergence and spread of antibiotic-resistant bacterial pathogens are a critical public health concern across the globe. Mobile genetic elements (MGEs) play an important role in the horizontal acquisition of antimicrobial resistance genes (ARGs) in bacteria. In this study, we have decoded the whole genome sequences of multidrug-resistant clinical isolates carrying the ARG-linked SXT, an integrative and conjugative element, in their large chromosomes.

With the advancements of science, antibiotics have emerged as an amazing gift to the human and animal healthcare sectors for the treatment of bacterial infections and other diseases. However, the evolution of new bacterial strains, along with excessive use and reckless consumption of antibiotics have led to the unfolding of antibiotic resistances to an excessive level. Multidrug resistance is a potential threat worldwide, and is escalating at an extremely high rate.

East Kolkata Wetlands (EKW) is designated as International Ramsar site and are the hotspot for large-scale wastewater aquaculture practices. However, the continued surveillance of physicochemical properties of water and application of an eco-friendly approach are essential to ensure safe aquaculture practices. In the present study, we assessed the seasonal variation in physicochemical parameters of water across EKW and investigated the role of nitrifying bacteria as probiotics.

In this study, the quantum chemical properties, nonbonding interactions, and spectroscopic insights of a wide variety of choline chloride (ChCl)-based deep eutectic solvents were investigated employing molecular dynamics (MD), density functional theory, and spectroscopic analyses. Nine experimentally reported ChCl-based deep eutectic solvents (DESs) were selected for this study where ChCl was common in all the DESs and the hydrogen bond donors (HBDs) were varied. The most energetically favorable cluster was selected using MD simulation followed by density functional theory calculation.

Background And Aims: Sevoflurane and desflurane have almost similar blood-gas solubility but recent studies suggest that desflurane compared to sevoflurane leads to faster recovery of airway reflexes, but the recovery of cognitive function varies significantly. We conducted this study to compare the times of recovery from anaesthesia following desflurane versus sevoflurane anaesthesia.

Methods: This randomised double-blinded study was conducted on 60 patients of American Society of Anesthesiologists (ASA) classification I-II, age between 18 and 60 years with body mass index (BMI) ≤30 kg/m who underwent elective cholecystectomy.

In this study, atomic level interactions of a 1:1 choline chloride (ChCl)/acetylsalicylic acid (ASA) therapeutic deep eutectic solvent (THDES) has been investigated by combining the molecular dynamics (MD), density functional theory (DFT), and spectroscopic (Raman and IR) techniques. Atom-atom radial distribution functions (RDFs) based on MD simulation reveal that hydrogen bonds are formed between Cl···HO and Cl···HO of the THDES, where Cl works as a bridge between ASA and Ch. Cation-anion electrostatic attractions are disrupted by highly interconnected hydrogen bonds.
