The association of hyperhomocysteinemia with acute post-operative complications following coronary artery bypass grafting.

Background: Hyperhomocysteinemia is associated with an increased risk for cardiovascular diseases. The influence of hyperhomocysteinemia on post-operative events, after coronary artery bypass surgery graft, is less studied.

Methods: This cross-sectional study aimed to determine if hyperhomocysteinemia was associated with post-operative complications in patients < 50 years who underwent off-pump coronary artery bypass graft for coronary artery disease.

Aortopulmonary window in adults: diagnosis and treatment of late-presenting patients.

Objectives: Aortopulmonary window is an uncommon condition, particularly so in adulthood because it is usually fatal in infancy or childhood if untreated. Very few cases of those who have survived to adulthood and been operated on successfully have been described. Our study aimed to provide clinical, investigative, surgical, and outcome details of such patients.

A highly effective one-pot synthesis of quinolines from o-nitroarylcarbaldehydes.

A highly effective one-pot Friedländer quinoline synthesis using inexpensive reagents has been developed. o-Nitroarylcarbaldehydes were reduced to o-aminoarylcarbaldehydes with iron in the presence of catalytic HCl (aq.) and subsequently condensed in situ with aldehydes or ketones to form mono- or di-substituted quinolines in high yields (66-100%).

3-[6-(2-Dimethylamino-1-imidazol-1-yl-butyl)-naphthalen-2-yloxy]-2,2-dimethyl-propionic acid as a highly potent and selective retinoic acid metabolic blocking agent.

3-[6-(2-Dimethylamino-1-imidazol-1-yl-butyl)-naphthalen-2-yloxy]-2,2-dimethyl-propionic acid and analogs were designed and synthesized as highly potent and selective CYP26 inhibitors, serving as retinoic acid metabolic blocking agents (RAMBAs), with demonstrated in vivo efficacy to increase the half-life of exogenous atRA.
