Different SNP Combinations in the GCH1 Gene and Use of Labor Analgesia [PDF]
, 2010 Background: The aim of this study was to investigate if there is an association between different SNP combinations in the guanosine triphosphate cyclohydrolase (GCH1) gene and a number of pain behavior related outcomes during labor.

Tetrahydrobiopterin protects soluble guanylate cyclase against oxidative inactivation
Pteridines, 2013 Tetrahydrobiopterin (BH4) is a major endogenous vasoprotective agent that improves endothelial function by increasing nitric oxide (NO) synthesis and scavenging of superoxide and peroxynitrite.

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]
, 2013 Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...

Molecular diagnosis of phenylketonuria: From defective protein to disease-causing gene mutation [PDF]
Journal of Medical Biochemistry, 2009 Phenylketonuria (PKU) is the most common inborn error of amino acid metabolism, with an average incidence of 1/10000 in Caucasians. PKU is caused by more than 500 mutations in the phenylalanine hydroxylase gene (PAH) which result in phenylalanine ...

Tetrahydrobiopterin, superoxide, and vascular dysfunction [PDF]
Free Radical Biology and Medicine, 2009 (6R)-5,6,7,8-Tetrahydrobiopterin (BH(4)) is an endogenously produced pterin that is found widely distributed in mammalian tissues. BH(4) works as a cofactor of aromatic amino acid hydroxylases and nitric oxide synthases. In the vasculature a deficit of BH(4) is implicated in the mechanisms of several diseases including atherosclerosis, hypertension ...

Maintenance of cellular tetrahydrobiopterin homeostasis
BMB Reports, 2010 Tetrahydrobiopterin (BH4) is a multifunctional cofactor of aromatic amino acid hydroxylases and nitric oxide synthase (NOS) as well as an intracellular antioxidant in animals. Through regulation of NOS activity BH4 plays a pivotal role not only in a variety of normal cellular functions but also in the pathogenesis of cardiovascular and ...

Reactive oxygen-related diseases: therapeutic targets and emerging clinical indications [PDF]
, 2015 SIGNIFICANCE Enhanced levels of reactive oxygen species (ROS) have been associated with different disease states. Most attempts to validate and exploit these associations by chronic antioxidant therapies have provided disappointing results. Hence, the
