Background: Coronary vein graft disease is an important contributor to the morbidity after coronary artery bypass graft surgery. Graft occlusion is a serious complication, which limits the use of the saphenous vein as a coronary bypass conduit. Asymmetrical dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthase and it reduces the bioavailability of nitric oxide and begets endothelial dysfunction.

The selectivity is explained in terms of hydrogen bonding between the hydroxy functionality of the allylic alcohol and the remote carbonyl group of the quinazolinone.

Background: Cigarette smoking increases the risk of cardiovascular events related with several mechanisms. The most suggested mechanism is increased activity of sympathetic nervous system. Heart rate variability (HRV) and heart rate turbulence (HRT) has been shown to be independent and powerful predictors of mortality in a specific group of cardiac patients.

A sirolimus-eluting stent (SES) had been deployed to the circumflex artery (Cx) 3 years before. Now, inferior ST-segment elevations were observed and coronary angiography revealed stent thrombosis with distal TIMI 3 grade flow in the Cx.

He did not have any allergic symptoms and there was no cutaneous or respiratory evidence of allergy on physical examination. Electrocardiographic and biochemical markers were consistent with an acute coronary syndrome.

Among these strains, isolate Trichothecium roseum EBK-18 was highly effective in the production of (R)-alcohols with excellent enantioselectivity (ee > 99%). Gram scale preparation of (R)-1-phenylethanol is reported.

Objectives: There had been evidence that low-dose local IFN could be beneficial in the management of recurrent oral ulcers (OUs). We investigated the efficacy and collected initial data on the safety of low-dose natural human IFN-alpha administered by the oral mucosal route in Behçet's syndrome (BS) in a placebo controlled, double blind study.
Methods: Eighty-four (59 males and 25 females) patients with BS with mainly skin mucosa disease and a history of recurrent OU for > or = 1 year were studied.
Atherosclerotic disease of the vertebro/basilar vessels is an important cause of posterior circulation infarction. Commonly, the primary atheroma forms at the origin of the vertebral arteries. Although initial treatment is medical, arch and four-vessel studies (CTA, MRA, or DSA) are warranted if symptoms continue.

The results indicate that treatment of a hypervalent iodine compound with hydrogen peroxide produces singlet molecular oxygen ((1)O(2)). Convergent evidence for the production of singlet molecular oxygen ((1)O(2)) by decomposition of hydrogen peroxide with a hypervalent iodine compound comes from chemical trapping experiments and the specific chemiluminescence detection of (1)O(2) at 1270 nm.

AF is the most common arrhythmia of the general population. Prehypertension, including those with systolic blood pressure ranging from 120-139 mmHg or diastolic blood pressure ranging from 80-89 mmHg was described by JNC7.

In the past few years, several experimental and clinical studies have investigated ways of enhancing myocardial salvage and regeneration. Although clinical evidence suggests that some treatment strategies might be able to enhance myocardial salvage and regeneration, many open questions remain, including the exact mechanisms leading to benefits, the influence of patient characteristics, optimal clinical indication and patient selection, and delivery method, route, and timing of therapies.

Chemoselectivity and diastereoselectivity of catalyst 1 are significantly affected by the structure of the allylic alcohol and the nature and amount of co-catalyst. More pronounced is the influence of the amount of added molar equivalents of H(2)O(2) (20-110 mol % with respect to the substrate).

Coronary embolism is an uncommon cause for myocardial infarction in clinical practice and there is no consensus on the treatment of this subject. Thrombolytic agents and percutaneous intervention are up to date options and yet there are only a few case reports regarding thrombolytic therapy in this special subgroup of patients suffering from myocardial infarction. We reported a 37-year-old woman patient with non-ST elevation myocardial infarction due to coronary embolism who was successfully treated using intravenous thrombolytic therapy with tissue plasminogen activator.
