A classification scheme for-lactamases based on functional characteristics is presented.
Three major groups of enzymes are defined by their substrate and inhibitor profiles: group 1 …

Two classification schemes for β-lactamases are currently in use. The molecular
classification is based on the amino acid sequence and divides β-lactamases into class A …

Carbapenemases are β-lactamases with versatile hydrolytic capacities. They have the ability
to hydrolyze penicillins, cephalosporins, monobactams, and carbapenems. Bacteria …

Objective To evaluate the 3 alcohol consumption questions from the Alcohol Use Disorders
Identification Test (AUDIT-C) as a brief screening test for heavy drinking and/or active …

Peroxynitrite anion (ONOO-) is a potent oxidant that mediates oxidation of both nonprotein
and protein sulfhydryls. Endothelial cells, macrophages, and neutrophils can generate …

Endothelial cells, macrophages, neutrophils, and neuronal cells generate superoxide (O 2−)
and nitric oxide (· NO) which can combine to form peroxynitrite anion (ONOO−) …

ABSTRACT A Klebsiella pneumoniae isolate showing moderate to high-level imipenem and
meropenem resistance was investigated. The MICs of both drugs were 16 μg/ml. The β …

As the record single-junction efficiencies of perovskite solar cells now rival those of copper
indium gallium selenide, cadmium telluride and multicrystalline silicon, they are becoming …

The development and spread of antibiotic resistance in bacteria is a universal threat to both
humans and animals that is generally not preventable but can nevertheless be controlled …

We demonstrate four-and two-terminal perovskite-perovskite tandem solar cells with ideally
matched band gaps. We develop an infrared-absorbing 1.2–electron volt band-gap …
