Ischemic colitis is now a well recognized clinical entity. The classification proposed by Marston(6) in three groups dependent on outcome . (Ischemic colitis with gangrene, Sit ecture Ischemic colitis, transient Ischemic colitis). Much has been writen recently con­cerning the radiographic diagnosis of Ischemic entro­colitis both occlusive and Monocclusive type(14). In nonocclusive type there ar...

Hypoxia-ischemia (HI) is the main cause of mortality in the perinatal period and morbidity, in survivors, which is characterized by neurological disabilities. The immature brain is highly susceptible to hypoxic-ischemic insult and is responsive to environmental stimuli, such as environmental enrichment (EE). Previous results indicate that EE recovered memory deficits in adult rats without rever...

Five minutes of global ischemia in gerbil results in delayed hippocampal CA1 neuronal degeneration, which is accompanied by working memory impairments and hyperactivity in novel environments. In this study, postischemic activity was characterized in familiar and in novel environments to determine whether hyperactivity was due to impaired spatial habituation or another form of motor hyperactivit...

Myocardial post-systolic shortening is characterized by a large variability in both duration and magnitude. Although typically occurring in a setting of ischemic heart disease, this regionally asynchronous myocardial contraction is considered a normal finding in approximately one-third of myocardial segments in healthy subjects, as long as the magnitude is low and the systolic strain is preserv...

objective: memory impairment is one of the most pervasive cognitive dysfunctions in schizophrenic patients. the aim of the current study was to conduct the most comprehensive assessment of how prospective memory (pm) is affected in schizophrenia in comparison with healthy controls. methods: in this study, 30 first-episode schizophrenic patients who fulfilled the diagnostic criteria of the diagn...
