To determine whether the energy balance of goats or characteristics of the diet consumed were the principal factors that determined milk production, feeding and digestion trials were carried out using two groups of 5 Granadina goats. The concentrate fraction of both diets was the same, but the forage fraction of the diets differed. In diet 1, the forage was(More)
OBJECTIVE The presence of serum rheumatoid factor (RF) and spontaneous RF-secreting B cells is a common feature in most patients with rheumatoid arthritis (RA). This study analyzed the cytokine(s) that controls the final maturation of B cells capable of spontaneous IgM-RF secretion in vitro. METHODS RA patients' peripheral blood mononuclear cells (PBMC),(More)
Cerebrospinal fluid (CSF) from multiple sclerosis (MS) patients contains B cells capable of spontaneous IgG secretion in vitro. This study analyses the function and regulation of these cells. CSF cells obtained from nine MS patients actively produced IgG during 2-3 days in culture, and the activity decreased when CSF cells were cultured in serum-free(More)
The objective of this study was to investigate the persistence of the effects of supplements after they were withdrawn. Two groups of 12 goats were maintained under semiextensive breeding conditions; they were fed indoors with a concentrate with alfalfa hay and olivetree leaves. Goats were in their sixth month of lactation at initiation of the study. During(More)
The purpose of this ex vivo study was to determine if severe malnutrition increases the frequency of micronuclei in spleen lymphocytes of experimentally malnourished rats during lactation. Micronucleus frequencies were analyzed in binucleate cells produced by the cytokinesis block method. The overall micronucleus frequency was significantly higher in(More)
This paper provides baseline information regarding the regulation of hematopoiesis in antiorthostatic, hypokinetic/hypodynamic ("suspended") laboratory rats. The object of the study was to compare the hematological effects of suspension with those seen following space flight in man and/or rats. Observed in man after exposure to microgravity and in the(More)
OBJECTIVE To examine the difference in force mechanisms between fatal and potentially survivable MVC aortic injuries (AI) compared to non-AI severe thoracic injuries (ST). METHODS Of 324 autopsied MVC driver or front seat passenger fatalities (1997-2000), there were 43 fatal AI (36 scene deaths, 7 hospital deaths) and 5 additional AI survivors. RESULTS(More)
Previous studies have shown that central injection of bombesin produces hypothermia in food-deprived, but not food satiated rats at normal ambient temperatures. The present study evaluated the effects of bombesin on core body temperature (Tb) and feeding behavior in rats pretreated with insulin. Administration of bombesin (0.25, 0.5, and 1.0 microgram) into(More)
