We measured arterio-venous differences in concentrations of tumor necrosis factor-alpha (TNF alpha) and interleukin-6 (IL-6) across a sc adipose tissue bed in the postabsorptive state in 39 subjects [22 women and 17 men; median age, 36 yr (interquartile range, 26-48 yr); body mass index, 31.8 kg/m2 (range, 22.3- 38.7 kg/m2); percent body fat, 28.7% (range,(More)
The expression of PECAM, ICAM-1, VCAM-1, and E-selectin was studied in 64 samples of human coronary arteries taken from 15 explanted hearts obtained within 5 min of transplantation. Normal artery (n = 12), predominantly fibrous plaques (n = 23), and plaques containing extracellular lipid (n = 26) and three segments showing recanalization channels were(More)
A murine model that closely resembles human cerebral malaria is presented, in which characteristic features of parasite sequestration and inflammation in the brain are clearly demonstrable. "Young" (BALB/c x C57BL/6)F(1) mice infected with Plasmodium berghei (ANKA) developed typical neurological symptoms 7 to 8 days later and then died, although their(More)
CD98 is expressed on both hematopoietic and nonhematopoietic cells and has been implicated in a variety of different aspects of cell physiology and immunobiology. In this study, the functional interactions between CD98 and other adhesion molecules on the surface of the promonocyte line U937 are examined by means of a quantitative assay of cell aggregation.(More)
Assembly of the inorganic core (Mn(4)O(x)Ca(1)Cl(y)) of the water oxidizing enzyme of oxygenic photosynthesis generates O(2) evolution capacity via the photodriven binding and photooxidation of the free inorganic cofactors within the cofactor-depleted enzyme (apo-WOC-PSII) by a process called photoactivation. Using in vitro photoactivation of spinach PSII(More)
The effects of long term treatment with 12-O-tetradecanoylphorbol-13-acetate (TPA) on estrogen receptor (ER) expression in the human breast cancer cell line, MCF-7, were studied. This study demonstrates that treatment of cells with the phorbol ester blocked estrogen receptor activity. Treatment of cells with 100 nM TPA resulted in an 80% decrease in the(More)
Abstract Two auditory lexical decision semantic priming experiments were conducted to examine the extent to which the automaticcontrolled processing dichotomy can characterize lexical access deficits in Broca's and Wernicke's aphasics. In Experiment 1, prime-target predictability was varied while the interval between prime and target (ISI) was held(More)
Quantitative measurement of NF-kappaB nuclear translocation is an important research tool in cellular immunology. Established methodologies have a number of limitations, such as poor sensitivity, high cost or dependence on cell lines. Novel imaging methods to measure nuclear translocation of transcriptionally active components of NF-kappaB are being used(More)
This study investigates the effects of hydrogen peroxide, a potent oxygen free radical donor, on the phenotype and function of dendritic cells differentiated from peripheral blood precursors. We report that hydrogen peroxide induces an up-regulation of several dendritic cell surface markers involved in interaction with T cells, including MHC Class II(More)
A four-alternative, forced choice adaptive procedure was used to measure the lowest intensity at which children could identify monosyllabic nouns that had been standardized to be understandable (at comfortable listening levels) to inner city, 3-year-old children. Results showed no age-related performance changes when the words were presented against a(More)
