Association of vitamin D receptor gene polymorphism (TaqI and Apa1) with bone mineral density in North Indian postmenopausal women.

Vitamin D receptor (VDR) gene has an important role as a candidate gene for the regulation of bone mass in osteoporosis. However, its association with bone mineral density (BMD) is controversial and has not been established in different ethnic populations. To enhance the understanding of VDR gene polymorphism in the context of BMD, we investigated the plausible genetic association of TaqI and ApaI polymorphism with BMD in North Indian postmenopausal women with osteoporosis.

Essential hypertension: A filtered serum based metabolomics study.

Despite the easy and reliable methods of blood pressure measurement, the screening of essential hypertension (EH) is usually ignored due to delayed onset of symptoms. A probe into the biochemical changes in hypertension would serve as a welcome asset to provide insight into the mechanistic aspects of EH. Filtered serum samples from 64 EH patients and 59 healthy controls (HC) were analysed using 800 MHz nuclear magnetic resonance (NMR) spectroscopy.

1H NMR-derived metabolomics of filtered serum of myocardial ischemia in unstable angina patients.

Background: Despite continuing research for development of accurate biomarkers of myocardial ischemia in unstable angina, lack of biochemical biomarkers is alarming. We sought to develop accurate biomarkers using high throughput proton nuclear magnetic resonance ((1)H NMR) spectroscopy and filtered serum (lacking proteins and lipoproteins) based metabolomics for detecting myocardial ischemia in unstable angina patients with utmost precision.

Methods: Study includes 127 filtered serum samples from myocardial ischemia in unstable angina patients (UA; n=65) and healthy controls (HC; n=62).
