Background. The study aimed to verify the effect of primary percutaneous coronary intervention (PPCI) with <60 min door-to-balloon time on ST segment elevation myocardial infarction (STEMI) patients' prognoses. Methods. Outcomes of patients receiving PPCI with door-to-balloon time of <60 min were compared with those of patients receiving PPCI with door-to-balloon time 60-90 min. Result. Totally...

Three levels of boron (0, 30, 60 ppm) were supplemented in practical corn-soybean based starter and grower diets, containing either adequate or inadequate Ca or P. A total of 1,800, 1-day-old sexed broiler chicks were assigned to six dietary treatments and fed with the experimental diets for 42 days. Boron improved the overall feed conversion ratio, but increased body weight only at 21 days of ...

PURPOSE To characterize the velocity of epithelial migration after photorefractive keratectomy (PRK) with 3 different corneal ablation patterns. SETTING Department of Ophthalmology, Catholic University of Rome, Rome, Italy. METHODS Fifteen patients (30 eyes) with mild to moderate myopia and with simple to compound myopic astigmatism were enrolled for this study. The surgical procedure consi...

A biochemical approach was employed to examine the oxidative utilization of carbohydrate and lipid in red muscle of rainbow trout (Oncorhynchus mykiss) during sustained swimming at 30 and 60% of their critical swimming speed (U(crit); for 2, 15 and 240 min) and during non-sustainable swimming at 90% U(crit) (for 2, 15 and 45 min). Measurements included pyruvate dehydrogenase (PDH) activity, cre...

Cyclic fatigue of nickel-titanium, engine-driven instruments was studied by determining the effect of canal curvature and operating speed on the breakage of Lightspeed instruments. A new method of canal curvature evaluation that addressed both angle and abruptness of curvature was introduced. Canal curvature was simulated by constructing six curved stainless-steel guide tubes with angles of cur...

Results Tolvaptan at all doses significantly reduced pulmonary capillary wedge pressure ( 6.4 4.1 mm Hg, 5.7 4.6 mm Hg, 5.7 4.3 mm Hg, and 4.2 4.6 mm Hg for the 15-mg, 30-mg, 60-mg, and placebo groups, respectively; p 0.05 for all tolvaptan vs. placebo). Tolvaptan also reduced right atrial pressure ( 4.4 6.9 mm Hg [p 0.05], 4.3 4.0 mm Hg [p 0.05], 3.5 3.6 mm Hg, and 3.0 3.0 mm Hg for the 15-mg,...

OBJECTIVES Brief episodes of ischemia and reperfusion after a lethal ischemic insult confer cardioprotection, a phenomenon termed "ischemic postconditioning." However, all studies reported to date have been conducted in open-chest animal models. We sought to determine whether postconditioning occurs in conscious animals and whether it protects against severe myocardial injury. METHODS Chronic...

Background: One of the important issues in aging is sarcopenia characterized by muscle mass and function reduction. The present study investigated the effect of high intensity interval resistance training (HIIRT) on muscular parameters in sarcopenic elderly women. Methods: A total of 30 sarcopenic women aged 60 to 70 years (appendicular skeletal muscle mass index<6.76 kg/m2, hand grip<20 kg) w...

THE effects of a high concentrate versus high fibre diet on performance parameters and welfare of the horse have been widely studied in the past (Tinker and others 1997, Nadeau and others 2000, McGreevy and others 2001, Ellis and others 2002). Horses fed diets low in ‘structural’ fibre have a greater susceptibility to develop stereotypical behaviour (apparently functionless, repetitive activiti...

The efficacy of ultrasound in removing cast metal posts was evaluated in this in vitro study using one or two ultrasound units and ultrasonic vibration for various lengths of time. The crowns of 30 healthy maxillary canines were removed, the roots were embedded in acrylic resin blocks, and the root canals were treated endodontically. The canals were prepared and their impressions were taken wit...
