Patients with Invasive Tumors and Gene Polymorphisms with Subarachnoid Hemorrhage Tend to Have Poorer Prognosis.

 Endothelial nitric oxide synthase ( gene polymorphisms are found to predict predisposition to aneurysmal rupture and development of vasospasm in a patient of subarachnoid hemorrhage (SAH). gene polymorphisms are also found to predict invasiveness of malignant cells. Studies are not available in literature to describe the effect of gene polymorphisms and correlation between aneurysm and carcinoma.

Estrogen receptor alpha gene variant, PvuII (rs2234693), as a potential pharmacogenetic biomarker for aneurysmal subarachnoid hemorrhage in postmenopausal women.

Aneurysmal subarachnoid hemorrhage (aSAH) occurs more often in postmenopausal women than in men. Estrogen plays an important role in vascular homeostasis. Our aim was to elucidate whether a drop in circulating estradiol in conjunction with variants of estrogen receptor genes have a role in female gender susceptibility to aSAH.

The vascular protective role of oestradiol: a focus on postmenopausal oestradiol deficiency and aneurysmal subarachnoid haemorrhage.

The steroid hormone, oestradiol, has pleiotropic functions. The protective effects of oestradiol are attributed to its anti-inflammatory, antioxidant, anti-atherogenic, anti-apoptotic, vasodilatory activities and regulation of micro RNA. Oestradiol upregulates endothelial nitric oxide synthase gene expression and increases the production of nitric oxide, an important vasodilator.

Correlation of ubiquitin C terminal hydrolase and S100β with cognitive deficits in young adults with mild traumatic brain injury.

Objective: To study the acute phase serum biomarkers in patients with mild traumatic brain injury (mTBI) and to correlate them with short term cognitive deficits.

Materials And Methods: This is a prospective observational study conducted at a tertiary care center for neurotrauma. The participants included patients with mTBI (n = 20) and age, gender, and education-status matched healthy controls (n = 20).

Correlation between plasma total nitric oxide levels and cerebral vasospasm and clinical outcome in patients with aneurysmal subarachnoid hemorrhage in Indian population.

Context: Cerebral vasospasm remains a major cause of morbidity and mortality in patients with aneurysmal subarachnoid hemorrhage (aSAH). Reduced bioavailability of nitric oxide has been associated with the development of cerebral vasospasm after aSAH. Such data is not available in Indian population.
