OBJECTIVE: Acute appendicitis is the most common abdominal emergency in children and young adults. There are a lot of serotonin-containing cells in the appendix, which release serotonin into the bloodstream in response to inflammation. Consequently, serotonin is converted to 5-hydroxyindoleacetic acid (5-HIAA) and secreted into the urine. On this basis, ...

BACKGROUND: Asymmetric dimethylarginine (ADMA) causes endothelial dysfunction by inhibiting endothelial nitric oxide synthase. Elevated ADMA plasma levels comprise a major risk factor for coronary artery disease (CAD) and predict coronary events. ADMA is metabolised by dimethylarginine dimethylaminohydrolases (DDAHs) to citrulline and dimethylamine (DMA) and is partly excreted unchanged via the ...

Intraventricular hemorrhage (IVH) predicts worse outcomes following aneurysmal subarachnoid hemorrhage (SAH). One potential mechanism is that IVH predisposes to the development of delayed ischemic neurological deficits (DINDs). No previous studies have evaluated the association between IVH volume (in milliliters) and subsequent development of DINDs or poor outcomes. To assess the ...
