Clinical and Translational Science Faculty Publications
Adipose tissue lipoprotein lipase (LPL) activity is decreased in patients with poorly controlled diabetes, and this contributes to the dyslipidemia of diabetes. To study the mechanism of this decrease in LPL, we studied adipose tissue LPL expression in male rats with streptozotocin-induced diabetes. Heparin releasable and extractable LPL activity in the epididymal fat decreased by 75-80% in the diabetic group and treatment of the rats with insulin prior to sacrifice reversed this effect. Northern blot analysis indicated no corresponding change in LPL mRNA levels. However, LPL synthetic rate, measured using [35S]methionine pulse labeling, was decreased by 75% in …

Numerous studies have shown estrogen to be vasoactive in various circulations. Our objective was to determine the effect of estrogen on isolated bovine coronary arteries and the possible mechanism. Bovine coronary arteries, precontracted with thromboxane mimetic U46619 were given doses (0.01-30μM) of 17Β-estradiol in the presence and absence of endothelium and these inhibitors: 10μM indomethacin (cyclooxygenase inhibitor), 10μM methylene blue (inhibits soluble guanylate cyclase), 100μM nitro-L-arginine (inhibits nitric oxide synthesis), 100μM isobutylmethylxanthine (phosphodiesterase inhibitor) and 30μM mifepristone (Ru38486 steroid receptor antagonist). Our results indicated that, estrogen, in the highest concentration used (30μM), elicited an acute dose-dependent relaxation of …
The Toxicology Of Aluminum In The Brain: A Review, Robert A. Yokel
The Toxicology Of Aluminum In The Brain: A Review, Robert A. Yokel
Pharmaceutical Sciences Faculty Publications
Aluminum is environmentally ubiquitous, providing human exposure. Usual human exposure is primarily dietary. The potential for significant Al absorption from the nasal cavity and direct distribution into the brain should be further investigated. Decreased renal function increases human risk of Al-induced accumulation and toxicity. Brain Al entry from blood may involve transferrin-receptor mediated endocytosis and a more rapid process transporting small molecular weight Al species. There appears to be Al efflux from the brain, probably as Al citrate. There is prolonged retention of a fraction of Al that enters the brain, suggesting the potential for accumulation with repeated exposure. Al …

Lobeline and nicotine evoke [3H]overflow from rat striatal slices preloaded with [3H]dopamine ([3H]DA). The lobeline-evoked overflow is calcium-independent and not antagonized by mecamylamine, suggesting a mechanism of action other than the stimulation of nicotinic receptors. Whereas nicotine stimulates nicotinic receptors, lobeline inhibits [3H]DA uptake into synaptic vesicles and striatal synaptosomes. The results suggest that different mechanisms are responsible for the increase in striatal DA release evoked by lobeline and nicotine.

Increased plasma concentrations of angiotension II (Ang II) have been implicated in atherogenesis. To examine this relationship directly, we infused Ang II or vehicle for 1 month via osmotic minipumps into mature apoE–/– mice. These doses of Ang II did not alter arterial blood pressure, body weight, serum cholesterol concentrations, or distribution of lipoprotein cholesterol. However, Ang II infusions promoted an increased severity of aortic atherosclerotic lesions. These Ang II–induced lesions were predominantly lipid-laden macrophages and lymphocytes; moreover, Ang II promoted a marked increase in the number of macrophages present in the adventitial tissue underlying lesions. Unexpectedly, pronounced abdominal …

Gill Heart & Vascular Institute Faculty Publications
Class A scavenger receptors (SR-A) mediate the uptake of modified low density lipoprotein (LDL) by macrophages. Although not typically associated with the activation of intracellular signaling cascades, results with peritoneal macrophages indicate that the SR-A ligand acetylated LDL (AcLDL) promotes activation of cytosolic kinases and phospholipases. These signaling responses were blocked by the treatment of cells with pertussis toxin (PTX) indicating that SR-A activates Gi/o-linked signaling pathways. The functional significance of SR-A-mediated Gi/o activation is not clear. In this study, we investigated the potential role of Gi/o activation in regulating SR-A-mediated lipoprotein uptake. Treatment of mouse …

How Much Asthma Is Occupationally Related?, David M. Mannino
How Much Asthma Is Occupationally Related?, David M. Mannino
David M. Mannino
Asthma is a chronic respiratory disease that is increasing in both prevalence and mortality in developed countries around the world. Occupational exposures to sensitizers and irritants are causes of both asthma cases and asthma exacerbations in adults. The determination of how many cases of asthma may be caused or worsened by occupational exposures is highly dependent on how asthma is defined, what constitutes work-relatedness, and what specific methodology is employed. Surveillance-based methods generally have found the lowest proportion of work-related asthma, ranging from 1-8% of cases. Other types of studies, using exposed-unexposed methodology or interviews of incident asthma cases, have …

This study presents evidence that phosphoinositide (PI) 3-kinase is involved in T cell Ca2+ signaling via a phosphatidylinositol 3,4,5-trisphosphate PI(3,4,5)P3-sensitive Ca2+entry pathway. First, exogenous PI(3,4,5)P3 at concentrations close to its physiological levels induces Ca2+ influx in T cells, whereas PI(3,4)P2, PI(4,5)P2, and PI(3)P have no effect on [Ca2+]i. This Ca2+ entry mechanism is cell type-specific as B cells and a number of cell lines examined do not respond to PI(3,4,5)P3 stimulation. Second, inhibition of PI 3-kinase by wortmannin and by overexpression of the …

Cytologic screening is an important diagnostic tool used to detect precancerous and cancerous lesions of the cervix. We studied the prevalence of cervical abnormalities, based on Pap smear results, in patients at the Outpatient Adolescent Clinic at West Virginia University. We found a high incidence of overall intraepithelial cell pathology (24%) in this group with 2.4% high grade and 9.9% low-grade lesions. These findings show that major cervical pathology is present in this age group. Furthermore, repeat smears at intervals of < one year were performed on 317 patients. Of these repeat smears, 7% changed from normal to abnormal in this period. Sexually active adolescent females should have Pap smears at least annually to detect abnormalities that may otherwise not be detected until they are more advanced and difficult to manage. Higher risk adolescents may need semiannual screening.

Remifentanil (4-methoxycarbonyl-4-[(1-oxopropyl)phyenylamino]-1- piperidinepropionic acid methyl ester) is a μ-opioid receptor agonist with considerable abuse potential in racing horses. The identification of its major equine urinary metabolite, 4-methoxycarbonyl-4-[(1- oxopropyl)phenylamino]-1-piperidinepropionic acid, an ester hydrolysis product of remifentanil is reported. Administration of remifentanil HCl (5 mg, intravenous) produced clear-cut locomotor responses, establishing the clinical efficacy of this dose. ELISA analysis of postadministration urine samples readily detected fentanyl equivalents in these samples. Mass spectrometric analysis, using solid-phase extraction and trimethylsilyl (TMS) derivatization, showed the urine samples contained parent remifentanil in low concentrations, peaking at 1 h. More significantly, a major peak was identified as …
