Prior reports indicate that about half of amblyopia patients successfully treated with occlusion subsequently require maintenance patching. This retrospective study was designed to discover what clinical characteristics might be associated with a stable outcome following primary occlusion. Included were 188 patients who: (1) had amblyopia related to strabismus, anisometropia or media opacity; a...

BACKGROUND Flow-mediated dilatation (FMD) of the peripheral arteries may be impaired in chronic heart failure (CHF), and this could contribute to the increased peripheral resistance and exercise intolerance that occur with this disease. Physical exercise improves the FMD of large conduit arteries in CHF, but whether a similar impairment also occurs in smaller arteries is unknown. The mechanisms...

Whereas previous studies have shown that opening of the mitochondrial ATP-sensitive K(+) (mitoK(ATP)) channel protects the adult heart against ischemia-reperfusion injury, it remains to be established whether this mechanism also operates in the developing heart. Isolated spontaneously beating hearts from 4-day-old chick embryos were subjected to 30 min of anoxia followed by 60 min of reoxygenat...

We present a quick and straightfoward way of input selection for neuro-fuzzy modeling using ANFIS. The method is tested on two real-world problems: the non-linear regression problem of automobile MPG (miles per gallon) prediction, and the nonlinear system identi-cation using the Box and Jenkins gas furnace data 1].

background: the problem of the environmental pollution by nanoparticles, which have recently entered the cycle of industries process in iran, is very important and can be prevented with applying the proper management approaches. one of the most practical compounds is zno nanoparticle. in the present study  the (lethal concentration-50) lc50 24hr and 48hr of zno nanoparticles exposed-to reactive...

BACKGROUND-Chronic heart failure (CHF) impairs the endothelium-dependent, flow-mediated dilation (FMD) of small arteries. However, whether chronic angiotensin-converting enzyme (ACE) inhibition affects the impairment of FMD in CHF is unknown. We investigated the effects of long-term ACE inhibition on the FMD of peripheral arteries in rats with CHF and the mechanism(s) involved. METHODS AND RESU...

BACKGROUND Aortic valve replacement (AVR) remains the gold standard treatment for symptomatic severe aortic stenosis (AS). For the past 10 years, transcatheter aortic valve implantation (TAVI) has been applied in patients with high surgical mortality and morbidity risks. The preliminary results of our TAVI patients are presented in this study. METHODS Ten high-risk patients with severe AS, fo...

INTRODUCTION We evaluated the potential preventive effects and mechanisms of intravenously preloaded mesenchymal stem cells (MSCs) for erectile dysfunction (ED) in a cavernous nerve (CN) injury model. METHODS Male Sprague-Dawley (SD) rats were used for this study. Rats were randomized into two groups. One group was intravenously preloaded with MSCs (1.0 × 10(6) cells in 1 mL total fluid volum...

Estimation of the pose of an object, or equivalently estimation of a rigid motion, is a prerequisite to many tasks in robotics like perception and manipulation. We want to estimate object poses, consisting of orientation and position of a target object, with 6 degrees of freedom (DOF). We use dual quaternions for the representation of the pose and Mixtures of Projected Gaussians as probability ...
