We report the detection of a transit egress by the ∼ 3.9-Jupiter-mass planet HD 80606b, an object in a highly-eccentric orbit (e ∼ 0.93) about its parent star of approximately solar type. The astrophysical reality of the signal of variability in HD 80606 is confirmed by observation with two independent telescope systems, and checks against several reference stars in the field. Differential phot...

Because of increases in the elderly population and diabetic patients, the proportion of elderly among dialysis patients has rapidly increased during the last decades. The mortality and morbidity of these elderly dialysis patients are obviously much higher than those of young patients, but large analytic studies about elderly dialysis patients' characteristics have rarely been published. The reg...

8523 Background: An increased risk for strokes has not been previously reported among HD survivors. This report examines the rate and risk factors for stroke in long-term survivors of HD. METHODS The CCSS is a multi-institutional cohort study of long-term (≥ 5 years) survivors who were diagnosed between 1970-1986. The rate of first occurrence of self-reported strokes was determined for HD sur...

Our study evaluated the differences between early and late hemodialysis (HD) initiation in the intensive care unit (ICU) according to the RIFLE (Risk, Injury, Failure, Loss, and End-stage renal failure) and AKIN (Acute Kidney Injury Network) classifications. On the assumption that early initiation of HD in critical patients according to the RIFLE and AKIN criteria decreases mortality, we retros...

BODY: Objectives : A new F-18 agent for PET myocardial perfusion imaging (BMS747158) has been shown to have excellent image quality in a Phase I clinical trial. In a subgroup of patients undergoing imaging with this agent in a Phase II clinical trial, we assessed if dual gated perfusion study is feasible and leads to improved image quality. We generated motion free perfusion images by combining...

The present study aimed to evaluate the role of autophagy in the protective effect of dexmedetomidine in lung injury caused by ischemia-reperfusion (IR) in rats. In total 48 adult male Sprague-Dawley rats were randomly divided into 6 groups (n=8) as follows: i) Sham group; ii) the IR group; iii) IR + 1 µg/kg dexmedetomidine preconditioning group (pre-LD); iv) IR + 10 µg/kg dexmedetomidine preco...

Achieving target international normalization ratio in haemodialysis patients with atrial fibrillation: is it feasible? Sir, Atrial fibrillation (AF), the commonest sustained arrhythmia in clinical practice, is associated with increased mortality and cardiovascular morbidity both in non-uraemic and (recently) dialysis patients. Standard treatment for permanent AF consists of oral anticoagulation...

Background: It has been reported that the survival of hemodialysis (HD) patients is poor, and the leading cause of death is cardiovascular disease. To identify high-risk patients and treat them carefully, we developed a scoring system to evaluate their 15-year prognosis in a prospective cohort study. Methods: We analyzed data from 312 and 310 patients to develop and validate the prediction mode...
