Adult growth hormone deficient patients are known to exhibit reduced sweating and their ability to thermoregulate is diminished. Treatment of these patients with recombinant human growth hormone (r-hGH) is claimed to reverse these abnormalities. We have investigated this claim, as well as the mechanism underlying these altered sweating responses in(More)
Data are analyzed from 5 patients who died suddenly during ambulatory electrocardiographic monitoring. Three of the patients were also assessed in terms of 2 recently developed indexes of heart rate (HR) variability. One of these, the standard deviation of RR intervals during successive 5-minute segments averaged over 24 hours, has been reported to be a(More)
On August 28, 1996, the US Food and Drug Administration (FDA) asserted jurisdiction over cigarettes and smokeless tobacco under the Federal Food, Drug, and Cosmetic Act. Under this Act, a product is a "drug" or "device" subject to FDA jurisdiction if it is "intended to affect the structure or any function of the body." The FDA determined that nicotine in(More)
The Gordon Holmes spinocerebellar ataxia syndrome (GHS) is associated with idiopathic hypogonadotrophic hypogonadism (IHH). There are conflicting reports in the literature as to whether the primary neuroendocrine defect is of hypothalamic GnRH secretion, as with most causes of IHH, or of pituitary resistance to GnRH action. Because of the anatomical(More)
Diabetes mellitus is the most common endocrine disease, accounting for over 200 million people affected worldwide. It is characterized by a lack of insulin secretion and/or increased cellular resistance to insulin, resulting in hyperglycemia and other metabolic disturbances. People with diabetes suffer from increased morbidity and premature mortality(More)
The effects of immunoglobulin preparations from hyperthyroid Graves' disease patients on primary cultures of thyroid cells have been studied at the mRNA level. Autoantibodies to the thyrotropin (TSH) receptor from these patients, which had been initially characterized by their ability to stimulate adenylate cyclase and inhibit the binding of radiolabelled(More)
Adaptive antibiotic resistance is a newly described phenomenon by which Acinetobacter baumannii induces efflux pump activity in response to host-associated environmental cues that may, in part, account for antibiotic treatment failures against clinically defined susceptible strains. To that end, during adaptation to growth in human serum, the organism(More)
The T cell proliferative responses of peripheral blood lymphocytes from 20 patients with autoimmune thyroid disease (AITD) and 20 healthy controls were analysed to immunoaffinity-purified thyroid peroxidase (TPO) and recombinant antigen preparations generated in Escherichia coli as glutathione-s-transferase fusion proteins. The epitope specificity of the T(More)
