Research on respiratory protection against biologic agents is important to address major
concerns such as occupational safety and terrorist attack. This review describes the literature …

The effect of chronic hypoxia-induced pulmonary hypertension on nitric oxide synthase (NOS)
in the lung is controversial. To clarify the regulation of endothelial and inducible NOS (…

Biosynthesis of nitric oxide (NO) requires L-arginine and molec- cultured bovine aortic
endothelial cells and RAW 264.7 macro-ular oxygen. Although the apparent Km values for L-…

Nitric oxide (NO) is a recently discovered messenger for the activation of soluble guanylate
cyclase in a wide variety of cell types. Although enzymes involved in NO synthesis have been …

Proteins and amino acids are important biomolecules which regulate key metabolic pathways
and serve as precursors for synthesis of biologically important substances; moreover, …

Expression and localization of nitric oxide synthase (NOS) in the lungs of chronically hypoxic
and normoxic rats were studied using both immunohistochemistry and NADPH diaphorase (…

Soil microorganisms play a major role in improving soil fertility and plant health. Symbiotic
arbuscular mycorrhizal fungi (AMF) form a key component of the soil microbial populations. …

Earthworms can live in decaying organic wastes and can degrade it into fine particulate
materials, which are rich in nutrients. Vermicomposting is the application of earthworm in …

Experiments were designed to investigate the role of oxygen tension on modulation of
endothelium-denved relaxing factor/nitric oxide (EDRF/NO) synthase activity. EDRF/NO synthase …

The objective of this study was to investigate the regulation of endothelial nitric oxide (NO)
synthase by NO. Partially purified endothelial NO synthase was exposed to authentic NO (10-…
