1. Application of a precision nutrition tool for growing and finishing pigs
ABSTRACT The objective of this study was to evaluate a growth model applied to adjust nutritional programs for growing and finishing pigs, in a commercial production context. The phase I (calibration) was conducted in a commercial pig production unit. The data were collected from a nutritional program, a feed program, and an animal profile. In experimental p

2. The relationship between renal warm ischemia time and glomerular loss. An experimental study in a pig model
Abstract Purpose: To investigate the glomerular number after different warm ischemia times. Methods: Thirty two pigs were assigned into four groups. Three groups (G10, G20, and G30) were treated with 10, 20, and 30 minutes of left renal warm ischemia. The sham group underwent the same surgery without renal ischemia. The animals were euthanized after 3 week

3. Continuous blood purification treatment for endotoxin-induced acute respiratory distress syndrome
This study aimed to explore the effects of continuous blood purification (CBP) treatment in pigs affected with acute respiratory distress syndrome (ARDS). A total of 12 healthy male pigs, weighing 12±1.8 kg, were randomly and equally assigned to the control and experimental groups. The ARDS pig model was prepared by intravenous injections of endotoxin (20 �

4. Surgical model pig ex vivo for venous dissection teaching in medical schools
Abstract Purpose: To investigate a method for development of surgical skills in medical students simulating venous dissection in surgical ex vivo pig model. Methods: Prospective, analytical, experimental, controlled study with four stages: selection, theoretical teaching, training and assessment. Sample of 312 students was divided into two groups: Group A

6. Experimental infection with the Toxoplasma gondii ME-49 strain in the Brazilian BR-1 mini pig is a suitable animal model for human toxoplasmosis
Toxoplasma gondii causes toxoplasmosis, a worldwide disease. Experimentation with pigs is necessary for the development of new therapeutic approaches to human diseases. BR-1 mini pigs were intramuscularly infected with T. gondii with tachyzoites (RH strain) or orally infected with cysts (ME-49 strain). Haematology and serum biochemistry were analysed and buf

7. Effects of ischemic preconditioning in a pig model of large-for-size liver transplantation
OBJECTIVE: In most cases of pediatric liver transplantation, the clinical scenario of large-for-size transplants can lead to hepatic dysfunction and a decreased blood supply to the liver graft. The objective of the present experimental investigation was to evaluate the effects of ischemic preconditioning on this clinical entity. METHODS: Eighteen pigs were

8. Effect of propranolol on capsular reaction around silicone implants in guinea pigs
PURPOSE: To evaluate the effect of propranolol on capsular architecture around silicone implants by measuring the inflammation, capsular thickness, and collagen fiber density, using a guinea pig experimental model.METHODS:Thirty six adult male guinea pigs randomly divided into two groups (n=18) were used. Each one received a silicone implant with textured-su

9. Anatomical study of the pigs temporal bone by microdissection
PURPOSE: Initial study of the pig`s temporal bone anatomy in order to enable a new experimental model in ear surgery. METHODS: Dissection of five temporal bones of Sus scrofa pigs obtained from UNIFESP - Surgical Skills Laboratory, removed with hole saw to avoid any injury and stored in formaldehyde 10% for better conservation. The microdissection in all fi

11. Ractopamine levels on performance, carcass characteristics and quality of pig meat
This study evaluated the effect of ractopamine (RAC) on the performance of finishing pigs and the meat quality of these animals. Seventy crossbred pigs (35 barrows and 35 females) selected for high gain of lean meat, with initial weight of 77.1±0.32 kg were distributed in randomized blocks with five treatments (0, 5, 10, 15, and 20 ppm RAC in the diet) and

Estudo experimental comparativo entre a derivação cavo-pulmonar associada ao suporte circulatório esquerdo e o suporte circulatório biventricular na falência aguda biventricular / Comparative experimental study between cavopulmonary anastomosis associated with left ventricular assist device support and biventricular circulatory assistance in acute biventricular failure
Background Right ventricular (RV) failure durinq left ventricular assist device (LVAD) support can result in severe hernodynarnic cornpromise with hiqh mortality. Objective: This study investiqated the acute effects of cavopulmonary anastomosis on L VAD performance and riqht ventricular myocardial compromise in comparison with isolated LVAD support and biven
