ackground In primary percutaneous coronary intervention for acute ST-segment elevation myocarial infarction (STEMI), the use of drug-eluting stents (DES) is still controversial. Several randomized ontrolled trials of DES, compared with bare-metal stents (BMS), with short-term follow-up showed a eduction in target lesion revascularization (TLR), but no differences in rates of cardiac death or re...

ell therapy may transform the treatment of acute and hronic heart disease, with an anticipated impact rivaling he results of revascularization and reperfusion therapies eveloped in the last 50 years. Through controversies over he mechanisms of cell therapy, engraftment, and differeniation, the biological and translational (1) studies perormed over the past decade shape the future of this very x...

purpose : to compare the 6-months anatomic and best corrected visual acuity (bcva) responses after primary intravitreal bevacizumab (ivb intravitreal avastin) and ivb plus macular photocoagulation (mpc) in diabetics with clinically significant macular edema (csme) methods : in this interventional randomized clinical trial (rct) 40 diabetics (80 eyes) with bilateral csme and non-proliferative di...

Copper, a strong prooxidant, may play a role in atherogenesis. Serum Cu and caeruloplasmin levels have been suggested to be independent risk factors for coronary heart disease operating through oxidative modification of low density lipoprotein. Fifty cases of Acute Myocardial Iinfarction and fifty age and sex-matched controls were recruited. Copper and ceruloplasmin levels were estimated in con...

lthough the incidence of ST-segment elevation myocarial infarction (STEMI) is declining in industrialized naions, there are still an estimated 500,000 events annually in he U.S. (1). Furthermore, the in-hospital mortality is 6% to %, and over 15% of survivors to discharge experience a ecurrent cardiovascular event by 6 months (2). Infarct size s the key determinant of outcome, and prompt reperf...

purpose: to evaluate the ability to predict visual outcome after penetrating keratoplasty (pkp) in patients with pseudophakic or aphakic corneal edema (pce or ace). methods: medical records of 34 patients (34 eyes) who underwent pkp for pce or ace during 1994-2004 in ahvaz were retrospectively analyzed for variables in the history and ocular examination before pkp and visual outcome after pkp. ...

the aims of this study were to determine some major biochemical alterations observed in first calving cows with udder edema during the periparturient period and to detect some associations between dietary factors and the disease. for that, the concentrations of some electrolytes (na+, k+, cl, ca2+, p and mg2+), lipid (triglycerides and cholesterol) markers and lipoproteins (hdl, ldl and vldl) a...

schemic preconditioning is the one maneuver that has onsistently been shown to reduce myocardial necrosis due o ischemia/reperfusion injury in experimental models (1). rief coronary occlusions of a few minutes to 10 min ollowed by brief reperfusion periods markedly reduce the ize of a subsequent myocardial infarction (MI) induced by longer coronary artery occlusion followed by reperfusion. he a...
