Late gadolinium enhancement (LGE) has been proposed as an independent predictor of ventricular arrhythmias. The purpose this study was to assess if myocardial scar characterization could enhance the risk stratification for life-threatening arrhythmias and sudden cardiac death (SCD). We included patients with indication ICD or CRT-D implantation who underwent magnetic resonance clinical proposes...
BACKGROUND Atrial fibrillation, the most common sustained disturbance of heart rhythm, is associated with a 5-fold increase in the incidence of ischemic stroke. METHODS AND RESULTS The National Hospital Discharge Survey was used to estimate the annual number and prevalence of hospitalizations with atrial fibrillation among men and women 35 years of age or older. From 1985 through 1999, hospit...
BACKGROUND We examined whether type of menopause affects sex differences in coronary heart disease (CHD) events and whether the impact is similar in blacks and whites. METHODS AND RESULTS Participants were enrolled in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort between 2003 and 2007 without CHD at baseline (n=23 086). Cox regression models were used to calcula...

Recent evidence indicates that the risk of being diagnosed with cancer in a tissue is strongly correlated (0.80) with the number of stem cell divisions accumulated by the tissue. Since cell division can generate random mutations during DNA replication, this correlation has been used to propose that cancer is largely caused by the accumulation of unavoidable mutations in driver genes. However, n...
Two luminous marine bacteria, strains LC2-065(T) and LC2-102, were isolated from seawater at Sagami Bay in Japan. These bacteria were Gram-negative, oxidase-negative, catalase-positive, motile and coccoid-rods. 16S rRNA gene sequence analysis and multilocus sequence analysis (MLSA) using six loci (ftsZ, gapA, gyrB, mreB, pyrH and topA) and sequence analysis of the alpha subunit of luciferase (l...
BACKGROUND AND PURPOSE The present study aimed to identify risk factors for mortality due to subarachnoid hemorrhage (SAH) using a comprehensive questionnaire from the Japan Collaborative Cohort (JACC) Study, a Japan-wide population-based prospective study. METHODS A total of 109,293 individuals (45,551 men and 63,742 women, aged 40 to 79 years) free of stroke at entry participated in the JAC...
Methods and Results-—Participants were enrolled in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort between 2003 and 2007 without CHD at baseline (n=23 086). Cox regression models were used to calculate the hazard of incident nonfatal CHD (definite or probable myocardial infarction) and acute CHD death, adjusting for age, age at last menstrual period <45 years, regio...
تخلخل سازند ماسه سنگی شوریجه از روی نگارهای چگالی و نوترون مربوط به یکی از چاه های اکتشافی نفت در شمال شرق ایران(سرخس) محاسبه شده است. همچنین از روی نگار صوتی همان چاه سرعت امواج تراکمی در همان عمق ها اندازه گیری شده اند. مقدار درصد رس موجود در ماتریکس سنگ در عمق های مختلف از نگار زمین شناسی به دست آمده است. از برازش خطی بین کمیت های تخلخل‘ ?‘ مقدار رس‘ c و سرعت امواج تراکمی‘ Vp‘ رابطه زیر برای...
This study examined the relationships between the left ventricular (LV) regional function, regional myocardial blood flow (RMBF), and myocellular necrosis after sudden proximal occlusion of the left anterior descending coronary artery (LAD) in 36 awake, unsedated dogs. Net wall thickening during systole (NET) was used to assess regional LV function, was expressed as percent control, and was mea...
