We compared the effects of glucose injection with those of saline or mannitol on ischemic brain damage and brain water content in a four-vessel occlusion (4-VO) rat model, which simultaneously causes severe forebrain ischemia and moderate hindbrain ischemia. Glucose given before onset of ischemia was followed by severe brain injury, with necrosis of the(More)
We studied 10 patients who survived for 2 to 8 weeks in a vegetative state, including 8 with cardiopulmonary failure and 2 with subarachnoid hemorrhage. Within days of onset, they regained brainstem function and awoke, but none had evidence of cognitive awareness. All patients opened their eyes within 2 weeks, and eight had roving conjugate eye movements.(More)
As the number of patients requiring operation for peptic ulcer disease (PUD) declines, presumed contemporary ulcer etiology has largely been derived from medically treated patients not subjected to surgery. The purpose of this study was to examine the specific causes of PUD in patients requiring surgery. Our Acute Care Surgical Service registry was(More)
Seven-day postnatal rats were rendered hyperglycemic by the SC injection of 50% glucose, following which they were exposed to hypoxia with 8% oxygen. The glucose-treated animals survived more than twice as long as saline-treated littermates. Other hyperglycemic and control rat pups were subjected to hypoxia-ischemia by unilateral common carotid artery(More)
This report presents the findings of a study of a 17-year-old male with a selective immunodeficiency to the Epstein-Barr virus, who died of a malignant lymphoma following clinical infectious mononucleosis. Autopsy findings and immunohistochemical techniques demonstrated a malignant lymphoma with B-lymphocyte characteristics which primarily involved the(More)
To determine whether the production of brain ischemia is modified by antiplatelet agents administered at the time of extracranial endothelial injury, we modified a four-vessel occlusion rat model so that an electrogenic platelet thrombus in one carotid artery produced cerebral ischemia. DC current was passed through an anode around the left carotid artery(More)
An extensive study of the factors that affect the interfacial assembly of bionanoparticles at the oil/water (O/W) interface is reported. Bionanoparticles, such as viruses, have distinctive structural properties due to the unique arrangement of their protein structures. The assembly process of such bionanoparticles at interfaces is governed by factors(More)
