OBJECTIVES In our investigations we have reported that photochemical reaction leading to brain ischemia can also be precipitated with visible light from a non-coherent light source. It was revealed that focal cerebral ischemia after photochemical reaction cause the alterations in the capillaries ultrastructure and perivascular spaces of the barrier-competent regions of the brain. The purpose of...
of two fundamental or ontological premises embedded in Marxism, one relating the social and the spatial Order binary options Ewell of capitalist societies and the other linking time and space, history and geography. These experiments are hampered by the risk of obtaining heterogeneous isolated brain microvessels and low yields of mRNA.
NH+4 ions, at a concentration (0.25 mM) similar to that found in the plasma of patients with hepatic encephalopathy, cause, in vitro, a significant stimulation of the uptake by brain microvessels of large neutral amino acids, without any effect on the uptake of alpha-methylaminoisobutyric acid, glutamic acid, or lysine. Such a stimulation occurs essentially through an increase of the maximal tr...
A model system for studying cerebral microvasculature is presented in which submerged in vitro brain slices are examined by computerized videomicroscopy. Brain slices are superfused continuously with artificial cerebrospinal fluid, while blood vessels are monitored using a transmission light microscope with water immersion objectives. The responses to well-characterized vasoactive compounds ind...
Background: Ultrasound (US) has been used in neuroprotection after cerebral ischemia, however the mechanism of action remains unclearly. We have previously shown the protective effect of ultrasound on infarction volume and brain edema in ischemic brain injured at normothermic condition. Ultrasound may also amplify the effect of fibrinolytic medications in thrombolysis process .We have also show...
