1. Anxiolytic-like and proneurogenic effects of Trichilia catigua ethyl-acetate fraction in mice with cerebral ischemia
Abstract Trichilia catigua A. Juss., Meliaceae, known as "catuaba" in Brazil, has been popularly used as a tonic for fatigue, impotence and memory deficits. Previously, we have demonstrated that T. catigua ethyl-acetate fraction exerted antidepressive-like effects in mice. Affective-like symptoms are also well recognized outcome of cerebral ischemia in clini

2. Phytogenic as feed additive for suckling dairy calves’ has a beneficial effect on animal health and performance
Abstract: The aim of this study was to evaluate whether the use phytogenic as feed additive of Holstein calves could exert beneficial effects on animal health and performance. Thirty newborn calves were randomly divided into two groups (control and treated), and the treated consisted of 10 g of the phytogenic product diluted in milk once a day for 30 days. B

3. Oxidative stress assessment in intestine of newborn rats submitted to hypoxia and reoxygenation with tadalafil
Abstract Purpose: To evaluate the functional and structural response of tadalafil effects in the intestinal mucosa, using an experimental model of hypoxia and reoxygenation injury in rats. Methods: The animals were divided into 4 groups: CTL, H/R, H/R+Td and M+Td. The newborn rats allocated in groups H/R, H/R+Td and M+Td were submitted twice a day, to a g

4. Does the rattle of Crotalus durissus terrificus reveal its dietary history?
Background Environmental devastation threatens the survival of many species, including venomous snakes such as the South American rattlesnake Crotalus durissus terrificus. This observation is based on the decrease of snakes collected and donated to Brazilian research institutes. Nevertheless, some individuals have managed to survive and procreate. The ques

5. Effect of chronic stress in newborn rats on the progression of ligature-induced-periodontitis in adulthood
PURPOSE: To investigate the effect chronic stress in newborn rats on the progression of ligature-induced-periodontitis in adulthood. METHODS: Ten couples of adult Wistar rats were selected for mating. After birth, the female and their respective offsprings were allocated into two groups. Ligature Group (LG): offsprings were only watched during breast-feeding

6. Angiotensin II type 1 receptor blockade partially attenuates hypoxia-induced pulmonary hypertension in newborn piglets: relationship with the nitrergic system
The objective of this study was to observe possible interactions between the renin-angiotensin and nitrergic systems in chronic hypoxia-induced pulmonary hypertension in newborn piglets. Thirteen chronically instrumented newborn piglets (6.3 ± 0.9 days; 2369 ± 491 g) were randomly assigned to receive saline (placebo, P) or the AT1 receptor (AT1-R) blocker

7. Hypoxia/reoxygenation-induced myocardial lesions in newborn piglets are related to interindividual variability and not to oxygen concentration
OBJECTIVE: Evaluation of myocardial histological changes in an experimental animal model of neonatal hypoxiareoxygenation. METHODS: Normocapnic hypoxia was induced in 40 male Landrace/Large White piglets. Reoxygenation was initiated when the animals developed bradycardia (HR <60 beats/min) or severe hypotension (MAP <15 mmHg). The animals were divided into f

8. Implicações da programação pré-natal sobre o desempenho subsequente, características de carcaça e qualidade de carne em suínos
The objective of the present study was to investigate the influence of pre-natal programming on postnatal development, carcass traits and meat quality in pigs. Two hundred and eighty new-born male piglets (DanBred x PIC terminal line), born to 4th- 6th parity sows and in litters of 10 to 15 pigs, were identified as falling into two birth weight groups: high

9. Um enfoque multigênico para a genealogia comparada de Betacoronavirus em bovinos e equinos / A multigene approach for a compared genealogy of Betacoronavirus from cattle and horses
Gastroenteritis is one of the leading causes of morbidity and mortality amongst young and newborn animals, often caused by multiple intestinal infections, being rotavirus and Bovine coronavirus (BCoV) the main viral causes in cattle. BCoV has a worldwide distribution and caused diarrhea in calves, winter dysentery in adult cattle and respiratory disease, whi

10. Sildenafil prevents the increase of extravascular lung water and pulmonary hypertension after meconium aspiration in newborn piglets
Meconium aspiration syndrome causes respiratory failure after birth and in vivo monitoring of pulmonary edema is difficult. The objective of the present study was to assess hemodynamic changes and edema measured by transcardiopulmonary thermodilution in low weight newborn piglets. Additionally, the effect of early administration of sildenafil (2 mg/kg vo, 30

11. Colostrum and Serum Protein Levels in Water Buffaloes.
Blood serum samples and colostrum of 17 Murrah water buffalo cows (Bubalus bubalis) were examined at birth as well as their offspring before the ingestion of colostrum at 1, 3, 6, 12, 24, 48, 72 and 96 hours after birth to determine the failure in the passive transfer of an-tibodies. The parameters studied included the total protein (TP), albumin (ALB), alph

12. Passive acquisition of protective antibodies reactive with Bordetella pertussis by the newborn via placental transfer and breastfeeding / Aquisição passiva de anticorpos protetores reativos com Bordetella pertussis pelo recém-nascido via transferência placentária e aleitamento materno
Pertussis is currently considered an important public health problem in developed countries. Although there is no evidence of an increase in the number of pertussis cases in our country, can not rule out the hypothesis of a future re-emergence of disease, as epidemiological data from some regions show an increase in incidence, indicating that probably there
