Stroke was the third leading cause of death in the United States in 1997. During 1950-1996, age-standardized stroke death rates declined 70% for the entire U.S. population; however, the decline varied among racial/ethnic populations. The estimated number of stroke deaths by race/ethnicity and age illustrate the differences in stroke mortality that may be used to direct prevention efforts. This ...

Heat stroke is associated with prolonged exposures to high air temperatures that usually occur in the summer months of July and August in Tokyo, Japan. Also during July and August, residents of Tokyo are often exposed simultaneously to high concentrations of air pollutants. To assess the impacts of these combined exposures, daily numbers of heat stroke emergency transport cases/million resident...

BACKGROUND AND PURPOSE Genetic factors influence risk for ischemic stroke and likely do so at multiple steps in the pathogenic process. Variants in genes related to inflammation contribute to risk of stroke. The purpose of this study was to confirm our earlier finding of an association between allele 2 of a variable number tandem repeat of the IL-1 receptor antagonist gene (IL1RN) and cerebrova...

We use direct numerical simulations to study control of jets in crossflow by axial pulsing. Our main idea is that pulsing generates vortex rings; the effect of pulsing on jets in crossflow can therefore be explained by studying the behavior of vortex rings in crossflow. A method is proposed that allows optimal values of pulsation frequency, modulation and energy to be estimated a priori. This i...

background: hemorrhagic transformation (ht) of ischemic stroke (is) is a detrimental complication. this study investigated the association between serum ferritin level and ht in patients with massive is of middle cerebral artery.   methods: thirty patients with massive is of middle cerebral artery were enrolled in this prospective cohort study. they were divided into two groups based on the ser...

background: according to the international reports, brain stroke is the main reason of death and disability. in ischemic stroke, early and precise classification of patients who may profit from conflicting finest therapeutic interference is necessary if enhanced effects in terms of survival are to be talented. due to uncomplicated, easy performance, and inexpensive method the aim of this prelim...

patients with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (melas) present with recurrent and partially reversible neurological deficits. lesions of melas classically cause a signal change in both the grey and white matter, predominantly in the occipital and parietal lobes. these lesions mimic infarction. here, we reported a case of melas with rare neuroimaging finding...

background: we intended to investigate the serum magnesium impact upon the disability after ischemic stroke. methods: a total of 67 ischemic stroke patients who less than 6 hours had passed from their attacks participated in this cross sectional study. we have measured their serum magnesium level and determined its correlation with their rankin disability score (rds) in the first 72 hours (rds0...

Traumatic brain injury (TBI) is an important public health problem, comparable to stroke in incidence and prevalence. Few interventions have proven efficacy in TBI, and clinical trials are, therefore, necessary to advance management in TBI. We describe the current clinical trial landscape in traumatic brain injury and compare it with the trial efforts for stroke. For this, we analysed all strok...
