High-fructose feeding causes diet-induced alterations of lipid metabolism and decreased insulin sensitivity with alterations of hepatic pyruvate dehydrogenase and hepatic very low-density lipoprotein secretion. Inflammatory cytokines also induce dramatic changes in lipid metabolism, particularly in serum triglycerides via increased hepatic secretion and/or(More)
OBJECTIVE To determine whether the administration of D-chiro-inositol, a putative insulin-sensitizing drug, would affect the concentration of circulating insulin, the levels of serum androgens, and the frequency of ovulation in lean women with the polycystic ovary syndrome. METHODS In 20 lean women (body mass index, 20.0 to 24.4 kg/m 2) who had the(More)
A radioimmunoassay (RIA) has been developed to measure antibodies against Brucella abortus in bovine serum and can be used in the diagnosis of bovine brucellosis. The RIA measures the amount of specific antibody of the IgG1 and IgG2 subclasses but is insensitive to IgM, a characteristic which may make it more suitable than the complement fixation test (CFT)(More)
BACKGROUND Among mouse genetic mutants that develop neural tube defects (NTDs), some respond to folic acid administration during early pregnancy, whereas NTDs in other mutants are not prevented. This parallels human NTDs, in which up to 30% of cases may be resistant to folic acid. Most spina bifida cases in the folic acid-resistant 'curly tail' mouse can be(More)
Aero engines are extremely reliable machines and operational failures are rare. However, currently great effort is being put into reducing the number of in-flight engine shutdowns, aborted takeoffs and flight delays through the use of advanced engine health monitoring technology. This represents a benefit to society through reduced delays, reduced anxiety(More)
CONTEXT GH insensitivity syndrome (GHIS), Laron syndrome, is characterized by severe short stature, high serum GH levels, and very low serum IGF-I and IGF-binding protein-3 (IGFBP-3) levels associated with a genetic defect of the GH receptor. Recombinant human (rh) IGF-I treatment at doses of 80-120 microg/kg given sc twice daily is effective in promoting(More)
Brucella-specific antibodies of different immunoglobulin classes were quantitatively evaluated with respect to their efficiency in serological tests for bovine brucellosis. IgM reacted more efficiently than IgG1 and IgG2 in both the Rose Bengal plate test and serum agglutination test. The complement fixation test was found to be slightly more sensitive to(More)
We have reported that nordihydroguaiaretic acid (NDGA) inhibits the tyrosine kinase activities of the IGF-1 receptor (IGF-1R) and the HER2 receptor in breast cancer cells. Herein, we studied the effects of NDGA on the growth of estrogen receptor (ER) positive MCF-7 cells engineered to overexpress HER2 (MCF-7/HER2-18). These cells are an in vitro model of(More)
BACKGROUND Nordihydroguaiaretic acid (NDGA) is an inhibitor of the IGF-1 receptor (IGF-1R) in breast and other cancers, and concomitantly inhibits tumor growth both in cultured cells and animals. The current study evaluates the effect of NDGA on the androgen-stimulated growth of human prostate cancer cells. METHODS LAPC-4 prostate cancer cells in tissue(More)
1. All free-living stages of the nematode parasite of sheep, Trichostrongylus colubriformis Giles, survived exposure to freezing temperatures in contact with water, with the exception of the first-stage juvenile (J1). The third-stage juvenile (J3) was the most resistant stage. The order of relative survival of the different stages was different from that of(More)
