Blend of secondary metabolites from mesquite to improve nutrient digestibility, microbial protein, efficient use of nitrogen, ruminal parameters, and blood metabolites in sheep.

Although chemical additives are able to improve the efficiency of ruminal fermentation, they can leave residues in the meat. However, a blend of secondary metabolites can improve ruminal fermentation without harming the population welfare. Five levels (0.

Phytogenic additive from Prosopis juliflora on populations of rumen ciliate protozoa and its correlation with nutrition of sheep.

We evaluated the effect of phytogenic additive Prosopis juliflora on populations of ruminal ciliated protozoa and its correlation with variables related to sheep nutrition. In this experiment, five cannulated adult Santa Ines ewes were submitted to the additive intake. Each animal received 6 mL of the extract daily.

Dengue associated with severe cutaneous leukocytoclastic vasculitis and pericardial effusion: a case report.

Dengue is a viral disease, caused by an arbovirus of the genus Flavivirus. In Brazil, its incidence rate is high with a broad clinical spectrum. This report discusses a rare case of dengue associated with cutaneous leukocytoclastic vasculitis and pericardial effusion with eminence of cardiac tamponade in a previously healthy patient with no comorbidities.

Thie expression of an intraspecific aggressive reaction in the face of a stressor agent alters the immune response in rats.

The repercussion on the immune response of the expression of intraspecific aggressiveness in the face of a stressor agent was investigated in rats. Ninety-day-old animals were divided into three groups: the control group (only immunological measurements were performed), the foot-shock (FS) (animals individually receiving FS), and the intraspecific aggressive response (IAR) group (animals receiving FS and presenting IAR). For immunological measurements, blood samples were collected promptly at 7 and 15 days after FS or IAR.

Malnutrition during brain growth spurt alters the effect of fluoxetine on aggressive behavior in adult rats.

Malnutrition effect during the suckling period on aggressive behavior was investigated in adult rats treated and not treated with fluoxetine, a selective serotonin reuptake inhibitor. Sixty-four Wistar male rats were allocated in two groups, according to their mothers' diet during lactation. The well-nourished group was fed by mothers receiving a 23% protein diet; the malnourished one by mothers receiving a 8% protein diet.
