Oxidative stress plays a critical role in the pathogenesis of upper and lower respiratory tract diseases, such as chronic rhinosinusitis with nasal polyps (CRSwNP), allergic rhinitis (AR), and asthma ...

In enzymes, this can be achieved either by orbital ... 3 provides a picture of a cofactor-independent oxygenase with both the substrate and molecular oxygen bound in a catalytically relevant ...

The team evaluated more than 4,000 clones before identifying an enzyme S N Ar1.3 that contains six mutations and is 160-fold more active than the parent enzyme.

Alkanes are major constituents of crude oil. They are also present at low concentrations in diverse non-contaminated because many living organisms produce them as chemo-attractants or as protecting ...

Elevated liver enzymes can occur for many reasons. Most often, elevated liver enzymes are temporary and resolve on their own without treatment. Occasionally, elevated liver enzymes require additional ...

As a highly efficient radical scavenger, Fe(III) reductant and chelating agent, ascorbate can prevent enzyme inactivation by the highly oxidizing reaction cycle intermediates and help stabilize the ...

Conventional fertilizers and pesticides are not sustainable for multiple reasons, including high delivery and usage inefficiency, considerable energy, and water inputs with adverse impact on the ...

pH is a measure of how acidic or alkaline a solution is. The diagram below shows what happens to an enzyme when denaturation occurs. Each enzyme has an optimum pH but it also has a working range ...

The aim of this study was to compare the analgesic efficacy and safety of nimesulide, a preferential cyclo-oxygenase type-2 inhibitor, with ibuprofen in the treatment of pain after tonsillectomy.

Temperature affects enzyme-catalysed reactions by influencing the rate at which they occur. For a reaction to occur between an enzyme and substrate the two molecules need to collide. At lower ...
