We investigated the functional impact of a recently described islet-specific loss of sympathetic nerves that occurs soon after the autoimmune destruction of beta cells in the BB diabetic rat (1). We found that the portal venous glucagon response to sympathetic nerve stimulation (SNS) was markedly impaired in newly diabetic BB rats (BB D). We next found a normal glucagon response to intravenous ...

Although platelet-derived growth factor (PDGF)-BB is thought to participate in vascular disorders, the mechanism of PDGF-induced vascular smooth muscle cell (SMC) proliferation is not fully understood. This study was undertaken to examine the role of c-Jun in PDGF-BB-induced proliferation of rat aortic SMCs. PDGF-BB (10 ng/mL) significantly increased activator protein (AP)-1 DNA binding activit...

Collaborative problem solving was compared in SecondLife (SL) and Blackboard (BB) and both technologies were compared with a face-toface (FTF) control condition. There were no performance differences overall, although FTF was quicker and preferred, followed by BB and SL. BB was perceived to be more usable, whereas SL provided better user experience. Worse performance was indicated by dislike of...

We demonstrate that human placenta is a convenient source of creatine kinase isoenzyme BB. We compare the physicochemical and catalytic properties with those of other creatine kinase isoenzymes: purified human abdominal muscle MM and brain BB. We also describe a stabilizing medium for creatine kinase BB. Human placental and brain BB have similar catalytic properties, the respective Km values fo...

The effect beta blockers (BB) may have on the sensitivity of the thallium treadmill test (Th-TMT) is controversial. The purpose of this study was to test the hypothesis that BB decrease the sensitivity of the Th-TMT. Two hundred three patients over a two-year period were identified who satisfied the following criteria. All had symptom-limited upright treadmill exercise tests with stress and red...

Recombinant platelet-derived growth factor (PDGF)-BB was expressed and secreted from yeast in order to study the structure-function relationships of this mitogen. A simple purification scheme has been developed which yields greater than 95% pure PDGF-BB. Analysis of this recombinant PDGF-BB shows partial proteolysis after arginine-32. Substitution of this arginine residue, or arginine-28 [a pot...

Human platelet-derived growth factor-BB (hPDGF-BB) is a basic polypeptide growth factor released from platelets at the injury site. It is a multifunctional molecule that regulates DNA synthesis and cell division and induces biological effects that are implicated in tissue repair, atherosclerosis, inflammatory responses, and neoplastic diseases. This paper is an overview of the toxicology data g...

Planar cell polarity (PCP) regulates basal body (BB) docking and positioning during cilia formation, but the underlying mechanisms remain elusive. In this study, we investigate the uncharacterized gene Flattop (Fltp) that is transcriptionally activated during PCP acquisition in ciliated tissues. Fltp knock-out mice show BB docking and ciliogenesis defects in multiciliated lung cells. Furthermor...

Although the clinical significance of CK-BB is not now fully understood, reports show that serum CK-BB is found in association with neoplastic disease of the stomach and prostate (12, 13). The recent finding of a higher concentration of CK-BB in medullary serum relative to that of peripheral serum (14) may lead to assays for CK-BB that are useful in the early diagnosis of metastatic disease inv...
