Ischemic brain injury is exacerbated by leukocyte infiltration and formation of vasogenic edema. In this study we demonstrate that intercellular adhesion molecule-1 (ICAM-1) is dramatically (3 to 15-fold) up-regulated in human cerebromicrovascular endothelial cells (HCEC) by a 16 h exposure to the cytokine, IL-1 beta (50-200 u/ml), the phorbol ester, TPA(More)
Secondary ischemic brain injury has been shown to develop as a consequence of inflammation and vasogenic brain edema. In this study we show that inflammatory cytokines and simulated in vitro ischemia stimulate the surface expression of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and endothelial-leukocyte adhesion(More)
Leukocyte infiltration into the brain has been implicated in the development of ischemic brain damage. In this study, simulated in vitro ischemia/reperfusion and IL-1beta were found to up-regulate both the expression of intercellular adhesion molecule- (ICAM-1) in cultured human cerebromicrovascular endothelial cells (HCEC) and the adhesion of allogenic(More)
A frequent, if not predominant, complaint of persons reporting symptoms of multiple chemical sensitivities (MCS) is that of heightened sensitivity to smells. In this study odor detection thresholds for phenyl ethyl alcohol (a major component of rose oil) and methyl ethyl ketone (a common solvent) were measured in 18 persons exhibiting symptoms of MCS and in(More)
The interaction between growth and calcium homeostasis was studied by comparing the responses of (a) fast-growing broiler chickens (Cobb) and slow-growing Leghorns, and (b) fast-growing chickens (Cobb) fed either high energy (12.13 kJ/g) or low energy (9.2 kJ/g) diets, to dietary calcium concentration ranging between 4 and 20 g/kg). Plasma calcium increased(More)
Over the past decade, the use of free flap transfers in head and neck surgery has led to remarkable advances in the reliability and the ultimate results of oromandibular reconstruction. Stable and retentive dental restorations have been achieved using enosseous implants placed directly into the vascularized bone flaps. However, the functional assessment of(More)
Maximal oxygen uptake (Vo2max) was predicted in 1,951 high school students aged 14 to 19 years--1,061 girls and 890 boys--from five different types of high school. The schools represented most of the ethnic groups. The mean Vo2max in the boys was 41.3 +/- 9.4 (SD), and in the girls, 34.7 +/- 10.1 ml - kg-1 - min-1; it was highest at the age of 16 in the(More)
A relatively small decrease in intraocular pressure secondary to submaximal work can be demonstrated when factors other than the work load itself are eliminated--diurnal variation, body position, and the effect of repeated examinations. A feedback mechanism that causes a return of IOP towards its normal value after work-induced decreases is postulated.
