Changes in delta ADC reflect intracranial pressure changes in craniosynostosis
BACKGROUND In patients with craniosynostosis, intracranial pressure (ICP) has been reported to increase even in the absence of overt symptoms. The early and non-invasive detection of intracranial hypertension is important for reducing the risk of abnormal brain development in pediatric patients. PURPOSE To assess whether the apparent diffusion coefficient (ADC) of white matter during the card...
متن کاملNeuropathological Changes in Brain Cortex and Hippocampus in a Rat Model of Alzheimer’s Disease
Background: Alzheimer’s disease (AD) is a neurodegenerative disorder with progressive loss of cognitive abilities and memory loss. The aim of this study was to compare neuropathological changes in hippocampus and brain cortex in a rat model of AD. Methods: Adult male Albino Wistar rats (weighing 250-300 g) were used for behavioral and histopathological studies. The rats were randomly assigned t...
متن کاملMembrane trafficking and osmotically induced volume changes in guard cells.
Guard cells rapidly adjust their plasma membrane surface area while responding to osmotically induced volume changes. Previous studies have shown that this process is associated with membrane internalization and remobilization. To investigate how guard cells maintain membrane integrity during rapid volume changes, the effects of two membrane trafficking inhibitors on the response of intact guar...
متن کاملEarly ADC changes in motor structures predict outcome of acute stroke better than lesion volume.
OBJECTIVES The lesion volume assessed from diffusion-weighted imaging (DWI) within the first six hours to first week following stroke onset has been proposed as a predictor of functional outcome in clinical studies. However, the prediction accuracy decreases when the DWI lesion volume is measured during the earliest stages of patient evaluation. In this study, our hypothesis was that the combin...
متن کاملIschemia-reperfusion injury-induced histological changes affecting early stage pressure ulcer development in a rat model.
Pressure ulcers (PU) are caused by the interplay of multiple factors including skin microcirculation. Ischemia-reperfusion (I/R) injury is considered a significant mechanism in the early stages of pressure ulcer development. The objective of this controlled, single-blinded in vivo study was to create a pressure-induced injury rat animal model and explore the possible mechanism and effects of...
