Day-night changes in c-fos expression in the fetal sheep suprachiasmatic nucleus at late gestation (1995)The suprachiasmatic nucleus (SCN) is a circadian oscillator in mammals and shows day-night changes in metabolic activity. To investigate whether the fetal sheep SCN behaves as a circadian oscillator, day-night changes in ...

(Oxford University, 1996)The differentia] capacity for steroid synthesis of human luteal cell subpopulations was investigated in a well defined cell culture system. Corpora lutea were enzymatically dissociated, and the two cell types were ...
-
(1996)Most Colombian populations stem from the admixture of Caucasians, Amerindians and Negroids. In the world these two latter ethnical groups show a significantly higher prevalence of epilepsy than the former one. We tested ...
-
(Oxford University Press, 1996)Although the importance of seminal plasma in the protection of spermatozoa against reactive oxygen species is well known, only a few studies have investigated its antioxidative properties and the possible relationship ...

(John Wiley and Sons Inc., 1996)1. The antinociceptive action of clonidine (Clon) and the interactions with α1, α2 adrenoceptor and opioid receptor antagonists was evaluated in mice by use of chemical algesiometric test (acetic acid writhing test). 2. ...
-
(1996)We tested the hypothesis that the llama fetus has a blunted cardiovascular chemoreflex response to hypoxemia by investigating the effects of acute hypoxemia on perfusion pressure, heart rate, and the distribution of the ...
-
(1996)ATP diphosphohydrolase from tegumental membranes of Schistosoma mansoni was solubilized with Triton X-100 plus deoxycholate and separated by preparative nondenaturing polyacrylamide gel electrophoresis. Two isoforms with ...
-
(1996)Background. Treatment with high dose vitamin A reduces complications and duration of hospitalization for children with measles. In respiratory syncytial virus (RSV) infection, as with measles, low serum vitamin A concentrations ...
-
(1995)Sparfloxacin is a new antimicrobial that, while maintaining a good activity against gram negative bacilli, has a better in vitro activity against gram positive bacteria such as S pneumoniae, intracellular pathogens and ...
-
(1996)This study tested the hypothesis whether over-the-counter benzodiazepine availability influenced patterns of benzodiazepine use, abuse, and dependence in Chile. If over-the-counter availability represents a major risk ...
-
(W.B. Saunders, 1996)This study examines premorbid personality traits from a self-reported and family-reported perspective on a group of unipolar major depression (n = 27), bipolar (n = 21), and schizophrenic (n = 16) recovered inpatients, and ...
-
(1996)Alcohol ingestion may promote lipid peroxidation, and the presence of polyunsaturated fatty acids in liver lipids may be essential for the generation of liver damage through this mechanism. The aim of this study is to ...
-
(Biophysical Society, 1996)Calsequestrin, a high-capacity, intermediate-affinity, calcium-binding protein present in the lumen of sarcoplasmic reticulum, undergoes extensive calcium-induced conformational changes at neutral pH that cause distinct ...
-
(1996)The bursting behavior of ryanodine-sensitive single Ca2+ release channels present in chicken cerebellum endoplasmic reticulum (ER), rat hippocampus ER, and frog and rabbit skeletal muscle sarcoplasmic reticulum was ...
-
(1996)Omeprazole may not eradicate Helicobacter pylori from the stomach but rather displace it from the antrum to the stomach body. This fact could interfere with colonization studies in patients receiving the drug. The aim of ...
-
(Elsevier Ltd, 1996)The UC Davis Air Quality Group has performed studies on urban air quality since 1973. Recently, with the active collaboration of scientists in Mexico and Chile, these studies have been extended to other Pacific Rim cities ...
-
(1996)This study tries to determine the relationship between intolerance of ambiguity and different psychiatric disorders classified according to DSM-III-R criteria in two different countries. Inpatients from the psychiatric ...
-
(Elsevier, 1996)A method for evaluating the proportion of bacteria attached to mineral sulfides is presented. The method is based on the determination of the rate of ferrous iron oxidation by attached bacteria on the mineral surfaces. The ...
-
(Endocrine Society, 1996)Several members of the neurotrophin (NT) family, including nerve growth factor (NGF), NT-3, and NT-4/5, are expressed in the mammalian ovary. As their respective receptor tyrosine kinases are also found in the gland, the ...
-
(1996)The nucleotide sequence of the βgIII(A) gene, encoding the extracellular β-1,3-glucanase II(A) (βgIII(A)) of the yeast-lytic actinomycete Oerskovia xanthineolytica LL G109, was determined. Sequence comparison shows that ...
