Telomeres are the specialized ends of chromosomes consisting of highly conserved repeat (5'-TTAGGG-3')(n) sequences. Lack of information regarding the existence of an in vivo telomere clock function in birds, conflicting data regarding telomere array length in the chicken model, and the paucity of molecular telomere information for other avian species led(More)
We report that a small population of neurons expresses both choline acetyltransferase and classical estrogen receptor immunoreactivity and they are found primarily in the bed nucleus of the stria terminalis. In short-term ovariectomized ageing mice (24 months, n = 5) there were 41.0 +/- 4.1% fewer of these double-labeled cells than in young (five months, n(More)
The distribution of 125I-alpha-bungarotoxin (alpha-BTX), a putative nicotinic cholinergic receptor ligand was studied both in vitro and in vivo in the suprachiasmatic nucleus (SCN), anterior hypothalamic area (AHA), and supraoptic nucleus (SON) of the hypothalamus. For in vitro studies 20 micron frozen frontal sections containing SCN were incubated with(More)
A lectin-biotin assay was developed for use in the specific detection of slime produced byStaphylococcus epidermidis RP62A and M187sp11 grown in a chemically defined medium. Mature biofilm was formed on polyvinylchloride (PVC) disks using a combined chemostat-modified Robbins device (MRD) model system. Specimens fixedin situ were: 1) stained with ruthenium(More)
Calcitonin was detected by RIA in sera from four marine species, leopard sharks (Triakis semifasciata), horn sharks (Heterodontus francisci), thornback rays (Platyrhinoides triseriata), and kelp bass (Paralabrax clathratus). These animals have levels of calcitonin and calcium higher than freshwater and terrestrial species have. The administration of salmon(More)
Long-term ovariectomy attenuates several neuroendocrine-dependent changes in reproductive function of aging female rodents, but the sites affected and underlying mechanisms are not known. This study was designed to identify effects of aging on hypothalamic-preoptic neurocytoarchitecture and to determine whether long-term ovariectomy attenuated any of those(More)
A permanent tissue-cultured cell line (designated OK) has been established from kidney tissue of an adult American opossum. The OK line has been characterized with respect to morphology, chromosome constitution, tissue-culture requirements, and attainable mitotic arrest. The cells are epithelial-like with a stable nondiploid chromosomal modal number of 23.(More)
Nonadherent marrow mononuclear cells enriched for hematopoietic progenitor cells were cultured in semisolid medium with recombinant human granulocyte-macrophage colony-stimulating factor for 9 days to form colony forming unit-granulocyte macrophage (CFU-GM) colonies. 1,25-Dihydroxyvitamin D was then gently layered over the cultures. After 2 weeks,(More)
Sprague-Dawley rats were oöphorectomized and after a 2-3 week recovery period were given daily injections of progesterone (2.0 mg/0.1 ml) for six consecutive days. On the fourth day of progesterone treatment 0.2 microgram of estradiol 17 beta was given in addition and the right uterine cornua were subjected to one of five experimental maneuvers. On the(More)
alpha-Bungarotoxin (alpha-BTX) has been used to label receptor binding sites on neural membranes. alpha-BTX fractions 2.2 and 3.3 were purified from Bungarus multicinctus by the method of Ravdin and Berg (1979) and we iodinated. There was no difference between these two fractions in their binding affinity or specificity of binding with hypothalamic(More)
