(Endocrine Society, 1996)A 24-h rhythm of plasma PRL is present in fetal sheep. This rhythm is synchronized to an environmental clue (zeitgeber). We determined whether the light-dark cycle (L:D) is a zeitgeber for the fetal PRL rhythm and, if ...
-
(1996)The aim of these experiments was to analyze neurite outgrowth during regeneration of opossum spinal cord isolated from Monodelphis domestica and maintained in culture for 3-5 days. Lesions were made by crushing with forceps. ...
-
(Elsevier Inc., 1996)Glutathione (GSH), trypanothione (T(SH)2) and glutathionyl spermidine (GSH-SP) concentrations were determined in the Tulahuen and LQ strains and the DM 28c clone of Trypanosoma cruzi. The concentrations of GSH, T(SH)2 and ...
-
(1996)We report the molecular cloning and characterisation of the first CK1 (casein kinase) gene of Drosophila melanogaster (dmCK1). The protein sequence (DMCK1) shares significant homology with other mammalian CK1 protein kinases ...
-
(1996)The fertilizing ability of stallion semen was analyzed using fresh and frozen samples, obtained before (June-July) or during (October-November) the breeding season. Thirty ejaculates obtained from 4 stallions, were used. ...
-
(1996)Background: Obesity is considered a protective factor for osteoporosis improving bone mass and maintaining higher levels of estrogen during menopause. Objective: To determine the association of obesity with bone mineral ...
-
(BioScientifica Ltd., 1996)To investigate the effects of testosterone and estradiol (E2) on growth hormone receptor (GH-R) gene expression, we measured GH-R mRNA levels in relation to the changes of sex steroid concentrations in the normal male ...
-
(1995)Since fluconazole achieves high urine concentrations, we assessed its usefulness in the treatment of urinary candidiasis. We studied 24 patients (8 male) aged 23 to 97 years old, that presented pyuria with a negative urine ...
-
(1996)The interaction of microtubule associated proteins (MAPs) with the microtubule system has been characterized in depth in neuronal cells from various mammalian species. These proteins interact with well-defined domains ...
-
(1996)From 1977 to 1986, Chile experienced an important typhoid fever epidemic, despite statistics that indicated apparently improving levels of sanitation of drinking water and sewage disposal. The lack of antibiotic resistance ...
-
(Academic Press, 1996)The role of cyclic AMP-dependent protein kinase (PKA) and systolic function during the development of left ventricular hypertrophy (LVH) still remain uncertain. The aim of this work is to study PKA activity and mechanical ...
-
(1996)Defects of androgen receptor gen (Xc 11-12) leadre cellular insensitivity to these steroids. Androgen action is curently measured 'in vitro' in cultures of fioroblosts from genral skin, since expression of the androgen ...
-
(American Society for Nutrition, 1996)Animal and human studies have shown that copper is involved in the function of several enzymes. Studies have also shown that copper is required for infant growth, host defense mechanisms, bone strength, red and white cell ...
-
(Blackwell Publishing Ltd, 1996)1. Fifty-five C-polymodal nociceptors innervating hairy skin in human volunteers were tested for discrete stimulus-response properties through microneurography. 2. All fifty-five units were responsive to mechanical and ...
-
(1996)Preincubation of peripheral blood lymphocytes (PBL) from drug-free, healthy volunteers with either the protein tyrosine kinase inhibitor genistein (GNT, n = 10, final concentration 200 μM) or the protein kinase A activator ...
-
(American Society for Nutrition, 1996)Acute copper toxicity is infrequent in humans. The evidence for chronic toxicity is derived principally from patients with Wilson disease and cases of infantile cirrhosis that were related to excessive copper intakes. The ...
-
(Elsevier GmbH, 1996)The development of an efficient immune response depends on the capacity of antigen-specific lymphocytes to migrate into secondary lymphoid organs. The first step in the process of lymphocyte extravasation involves lymphocyte ...
-
(Blackwell Publishing Ltd, 1996)The protein kinase casein kinase 2 (CK2) is ubiquitous in eukaryotic cells and is apparently involved in the control of cell division. The holoenzyme is a tetramer composed of two catalytic subunits (α and/or α') and ...
-
(1996)The search for mechanisms responsible for the high sensitivity and sharp frequency tuning of first-order auditory neurons has produced surprising results. The cochlea, the mammalian auditory receptor, responds to acoustic ...
-
(1996)System y+L is a broad-scope amino acid transporter which binds and translocates cationic and neutral amino acids. Na+ replacement with K+ does not affect lysine transport, but markedly decreases the affinity of the transporter ...
