Urease is a bacterial enzyme that is responsible for virulence of various pathogenic bacteria such as Staphylococcus aureus, Proteus mirabilis, Klebsiella pneumoniae, Ureaplasma urealyticum, Helicobacter pylori and Mycobacterium tuberculosis. Increased urease activity aids in survival and colonization of pathogenic bacteria causing several disorders especially gastric ulceration. Hence, urease inhibitors are used for treatment of such diseases. In search of new molecules with better urease inhibitory activity, herein we report a series of acridine derived (thio)semicarbazones (4a-4e, 6a-6l) that were found to be active against urease enzyme. Molecular docking studies were carried out to better comprehend the preferential mode of binding of these compounds against urease enzyme. Docking against urease from pathogenic bacterium S. pasteurii was also carried out with favorable results. In silico ADME evaluation was done to determine drug likeness of synthesized compounds.

Introduction: () is becoming more resistant to antibiotics, and the implementation of individualized therapy is highly valuable for its eradication. This study aimed to investigate the efficacy and safety of individualized treatment guided by antibiotic susceptibility testing (AST) with a 10-day or 14-day course for the eradication of .
Methods: This was a prospective, open-label, single-center, quasi-randomized trial in which 220 participants were randomized into groups based on AST results as AST-10-day ( = 98) and AST-14-day ( = 112) treatment groups.

The complex contains important opportunistic pathogens of humans and vertebrate animals, as well as insects and other invertebrates. To date, the methods used for the identification of species within the genus , including PCR assays, have poor discriminatory power and may require further molecular typing or genomic sequence analysis to determine clinical relevance. We developed a duplex TaqMan probe-based quantitative real-time PCR (qPCR) assay targeting the gene, which is involved in chitin degradation and transport, and the gene, which is involved in urease production.

E-selectin (CD62E) is an adhesion molecule expressed on the surface of endothelial cells (ECs) and its level increases significantly upon the stimulation of ECs by inflammatory factors. Quantitative analysis of CD62E is of great importance to early diagnosis and treatment of vascular diseases and hypertension. A new method for the determination of CD62E was developed using a portable pH meter in this work.

This study investigates the potential of microbial-induced calcium carbonate precipitation (MICP) for soil stabilization and heavy metal immobilization, utilizing landfill leachate-derived ureolytic consortium. Experimental conditions identified yeast extract-based media as most effective for bacterial growth, urease activity, and calcite formation compared to nutrient broth and brown sugar media. Optimal MICP conditions, at pH 8-9 and 30 °C, supported the most efficient biomineralization.
