This preclinical evaluation demonstrates the safety and efficacy of a novel cobalt chromium stent with a carbon-carbon coating and low and medium doses of paclitaxel.

Our results confirm that diet and exercise routines significantly affect the serum lipid profile. Obesity and overweight constitute a risk factor for the development of hypercholesterolaemia and hypertriglyceridaemia.

The pattern of angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism in the Indian population is poorly known. The population has cultural and linguistic differences and lived in an environment that varied significantly from one region to another. There is controversy regarding the association of the Angiotensin-converting enzyme insertion/deletion polymorphism with essential hypertension and variation in blood pressure. In the present study we examined the importance of ACE (I/D) polymorphism as a determinant of hypertension and to assess the potential modifying effect of gender on ACE gene in Indian population. The ACE I/ D polymorphism was assayed by PCR amplification of ACE gene in 200 hypertension patients and 200 controls. The genotypic and allelic frequencies were observed to be deviated significantly from Hardey-Weinberg equilibrium (p<0.05). The DD and ID genotypes were found to be strongly associated with hypertension in men with an odds ratio 2.25 (95% confidence level (CI), 1.14 to 4.42) and 2.20 (95% CI, 1.27 to 3.80) respectively, (p<0.01). Further, a linear relationship was observed between diastolic pressure and allele D in men but not in women. The data thus provide evidence in favor of an association of I/D polymorphism at the ACE locus (17q23) with essential hypertension. Moreover, these results highlight the potential importance of gender-dependent interactions between genetic background and expression of hypertensive phenotype. It further prompts the need for the confirmatory studies in large population-based samples.
