Peripheral Arterial Disease (PAD) is a cause of significant morbidity and mortality in the Western world. Risk factor modification and endovascular and surgical revascularisation are the main treatment options at present. However, a significant number of patients still require major amputation. There is evidence that nitric oxide (NO) and its endogenous inhibitor asymmetric dimethylarginine (AD...

ADMA (asymmetric dimethylarginine) is a cardiovascular risk factor and an endogenous inhibitor of NOS (nitric oxide synthase). ADMA is metabolized by DDAHs (dimethylarginine dimethylaminohydrolases). ADMA levels are increased in cardiovascular disorders associated with abnormal angiogenesis but the mechanisms are poorly understood. Recent studies show that altering ADMA metabolism in vivo and i...

Cadmium (Cd(2+)) is a toxic heavy metal and a well-known human carcinogen. The toxic effects of Cd(2+) on biological systems are diverse and thought to be exerted through a complex array of mechanisms. Despite the large number of studies aimed to elucidate the toxic mechanisms of action of Cd(2+), few have been targeted toward investigating the ability of Cd(2+) to disrupt multiple cellular pat...

OBJECTIVE To determine the role of asymmetric dimethylarginine (ADMA) in acute lung injury induced by cerebral ischemia/reperfusion (I/R) injury in rats. METHODS Adult male SD rats were randomly divided into 4 groups, namely the sham-operated group (S), cerebral I/R model group, ADMA+I/R group, and dimethylarginine dimethylaminohydrolase (DDAH)+I/R group. In the latter 3 groups, acute lung in...
