Refining the perfusion-diffusion mismatch hypothesis.
BACKGROUND AND PURPOSE The Echoplanar Imaging Thrombolysis Evaluation Trial (EPITHET) tests the hypothesis that perfusion-weighted imaging (PWI)-diffusion-weighted imaging (DWI) mismatch predicts the response to thrombolysis. There is no accepted standardized definition of PWI-DWI mismatch. We compared common mismatch definitions in the initial 40 EPITHET patients. METHODS Raw perfusion image...
متن کاملMicroecology of Blastomyces dermatitidis: the ammonia hypothesis.
The precise microecology of Blastomyces dermatitidis is unknown, but the fungus has been associated with nitrogenous waste products and rapidly changing environmental conditions. Ammonia accumulates in certain microenvironments, is toxic to most fungi, but may not be identified in processed soil samples. Ammonia tolerance of B. dermatitidis was investigated with two strains recovered in Wiscons...
متن کاملNetwork Dysfunction in Alzheimer's Disease: Refining the Disconnection Hypothesis
Much effort in recent years has focused on understanding the effects of Alzheimer's disease (AD) on neural function. This effort has resulted in an enormous number of papers describing different facets of the functional derangement seen in AD. A particularly important tool for these investigations has been resting-state functional connectivity. Attempts to comprehensively synthesize resting-sta...
متن کاملThe Ammonia Hypothesis of Hepatic Encephalopathy should be Revisited
Hepatic Encephalopathy (HE) is a neurological complication of the brain following liver damage that was classically thought of being a functional decline in neuronal activity due to metabolic disturbances [1]. Acute liver failure as well as chronic liver diseases can cause HE, with the progression of HE correlating to the severity of liver damage [2]. Initially there are disturbances in cogniti...
متن کاملRefining the oak-fire hypothesis for managment of oak-dominated forests of the eastern United States
scape and consider the stages during oak life history where fire could potentially be used as a tool to enhance oak regeneration. Finally, we provide some guidance for management considerations in the field. The Oak–Fire Hypothesis: Issues in Contemporary Forests The oak–fire hypothesis suggests that oak forests require periodic fire disturbances for their successful regeneration and conservati...
