In this Review, we systematically synthesize publications and submissions to regulatory agencies describing technologies that provide phenotypic AST faster than conventional methods. We characterize over ninety technologies in terms of...

Measuring host response markers of inflammation and endothelial activation at clinical presentation may help to inform appropriate triage and care practices in patients with SARS-CoV-2 infection.

Microbes produce small molecules to interact with each other as well as to modulate their environments. Their metabolic profiles hold the key to understanding these association patterns for translational applications. Based on this concept, we developed MicrobiomeNet, a comprehensive database that integrates microbial associations with their metabolic...

Penile, anorectal, and oral exposures predicted lesion presence at correlating anatomic sites. Exposure site also predicted the first lesion site of the penis and anus.

The extraction was done using maceration at room temperature in water for 48 h. The synthesized nanoparticles were characterized by IR, XRD, TEM, and SEM. The thermal stability of these nanoparticles was studied by TGA. The zeta potential was used to define the size, charge distribution, and stability of the nanoparticles. Optimization reactions were carried out based on reaction...

The main objective of this study is to describe the epidemiology surrounding H. pylori in Nunavik's Inuit population using the 2004 and 2017 Health Surveys. Estimated prevalences were 70.9% for bacterial colonisation using a stool antigens test (SAT), 72.5% for anti-H. pylori antibodies, 12.7% for faecal occult...

The MICs of MO extract for microbial strains is 0.73 mg/ml for Escherichia coli, Pseudomonas aeruginosa, 7.5 mg/ml for Enterococcus faecalis, Staphylococcus aureus and 0.5 mg/ml for Candida albicans. The MO extract has an IC(50) of 3.403 mg/ml has an antioxidant activity by DPPH radical scavenging. The cytotoxic... Wed, 11 Sep 2024 06:00:00 -0400
