Correlative studies of cortical blood flow measured by the Kr washout technique and observations of the cortical blood vessels of 10 squirrel monkeys subjected to temporary occlusion of the middle cerebral artery are described. During occlusion, cortical blood flow in core areas of ischemia decreased to 0.12 to 0.90 ml/g/min (20 to 50% of preocclusion values) and became pressure dependent with ...

T2 relaxation can augment delayed-enhancement viability imaging because it is sensitive to tissue edema and microcirculatory oxygen state. We demonstrate the T2 'signatures' of sub-lethal ischemia and stunning in porcine myocardium perfused by the distal left anterior descending artery, by imaging during percutaneous balloon occlusion for 25 minutes and subsequent reperfusion (n = 9). Muscle di...

BACKGROUND Choice of appropriate MR pulse sequence is important for any research studies using imaging-derived data. The aim of this study was to compare semiquantitative assessment of subchondral bone marrow edema-like lesions and subchondral cysts using intermediate-weighted (IW) fat-suppressed (fs) spin echo and Dual Echo Steady State (DESS) sequences on 3 T MRI. METHODS Included were 201 ...

ABSTRACT: The objective of this study was to describe a case salmonellosis in an Amazonian manatee (Trichechus inunguis). animal rescued from tributary the Capim River, municipality Goianésia do Pará, Brazil, kept pool, and died approximately five months after being rescued. main changes observed at necropsy were that cecum colon had serosal hyperemia, wall edema, thickened mucosa with ulcerate...

Purpose Sporotrichosis is a subcutaneous mycosis caused by Sporothrix sp., a dimorphic fungus. Although the cutaneous form is the most frequent form, the ocular presentation has been increasingly diagnosed in epidemic areas. We describe three cases of ocular sporotrichosis with the involvement of the ocular adnexa due to autoinoculation without trauma with successful antifungal treatment. Obs...
