BACKGROUND AND PURPOSE Transient ischemic attack (TIA) in children has received far less attention compared with TIA in adults. The risk factors of stroke after TIA in children are relatively unknown. We aimed to determine the percentage of children who have stroke after TIA and the risk factors associated with stroke after TIA. METHODS We searched the medical records at Boston Children's Hos...

In vitro studies have shown that enterotoxigenic Escherichia coli (ETEC) strains are capable of invading cultured epithelial cells derived from the human ileum and colon. Two separate invasion loci (tia and tib) have previously been isolated from the classical ETEC strain H10407. The tia locus has been shown to direct the synthesis of Tia, a 25-kDa outer membrane protein. Tia is sufficient to c...

Transient Ischemic A t tacks and Risk of Stroke in an Elderly Poor Population • The significance for stroke and correlates of transient ischemic attacks (TIA) were studied prospectively in a population of 2,772 persons aged 65 to 74. The prevalence of TIA at the beginning of the study was 63 per 1,000. TIA prevalence was substantially higher among blacks and women than among whites and men. Onl...

The epidemiological characteristics of transient ischemic attacks (TIAs) in China are unclear. In 2013, we conducted a nationally representative, door-to-door epidemiological survey on TIA in China using a complex, multistage, probability sampling design. Results showed that the weighted prevalence of TIA in China was 103.3 [95% confidence interval (CI): 83.9-127.2] per 100,000 in the populatio...

BACKGROUND AND PURPOSE There is scant information available on the incidence of transient ischemic attack (TIA) in a defined population. This study defines incidence rates of first TIA and subtypes of TIA during 1985-1989 and compares the incidence to that obtained from a 1960-1972 cohort study. METHODS Medical records of all residents of Rochester with potential diagnosis of TIA during 1985-...

En este trabajo de investigación se presenta el diseño un sistema clasificación cajas basado en la visión artificial, cual permite detectar color cada una las que entran a estación. El basa implementación robot cilíndrico, cartesiano (cada uno con su respectivo PLC) y banda transportadora. funcionamiento empieza detección mediante sensor capacitivo, activa al cilíndrico para posicionar transpor...

This paper describes the version of GTE's Text Interpretation Aid (TIA) system used for participation in th e Third Message Understanding Conference (MUC-3) . Since 1985, GTE has developed and delivered three systems that automatically generate database records from text messages . These are the original TIA, the Alternate Domain Tex t Interpretation Aid (AD-TIA) and the Long Range Cruise Missi...

BACKGROUND AND PURPOSE Compared with ischemic stroke (IS), the association of atrial fibrillation (AF) with transient ischemic attack (TIA) is less well established. We aimed to assess the proportion of AF in patients with TIA, and these patients' characteristics and secondary preventive treatment in comparison to patients with IS. METHODS Hospital-based data on TIA and IS events, registered ...

background: stroke, one of the most important causes of morbidity and mortality in the world, is of great importance in young adults (15-45 years), amongst whom the causes of stroke and transient ischemic attack (tia) are different from those in older ages and a significant portion of them have no known etiology. patent foramen ovale (pfo) is considered a probable cause in this group. methods: ...
