25. Portable model for vasectomy reversal training
ABSTRACT Objectives To validate an experimental non-animal model for training of vasectomy reversal. Materials and Methods The model consisted of two artificial vas deferens, made with silicon tubes, covered by a white resin, measuring 10 cm (length) and internal and external diameters of 0.5 and 1.5 mm, respectively. The holder of the ducts is made by a

26. Effects of 1,25-dihydroxyvitamin D3 on experimental periodontitis and AhR/NF-κB/NLRP3 inflammasome pathway in a mouse model
Abstract Vitamin D has been known to have important regulatory functions in inflammation and immune response and shows inhibitory effects on experimental periodontitis in animal models. However, the potential mechanism has yet to be clarified. Recent studies have highlighted Aryl hydrocarbon receptor (AhR) and its downstream signaling as a crucial regulator

27. Modelling beef cattle production systems from the Pampas in Brazil to assess intensification options
ABSTRACT Traditional livestock productivity is hard to estimate, since it depends on a gamut of animal production indicators that are difficult to measure for many farms. Thus, we propose an analytical method for estimating productivity and understanding the importance of animal production indicators under different full-cycle cattle production systems in Br

28. The use of Arthrospira platensis in rearing Nile tilapia (Oreochromis niloticus) in salt water
RESUMO A tilápia do Nilo (Oreochromis niloticus) é uma espécie eurialiana e em sistemas marinhos é capaz de fornecer proteína animal onde a água doce é escassa. Com isso, torna-se imprescindível o gerenciamento adequado da água para manutenção da sustentabilidade, e o uso do sistema de recirculação de água salgada seria vantajoso para o atual m

29. Fluorofenidone inhibits apoptosis of renal tubular epithelial cells in rats with renal interstitial fibrosis
This study aimed to investigate the mechanism of fluorofenidone (AKF-PD) in treating renal interstitial fibrosis in rats with unilateral urinary obstruction (UUO). Thirty-two male Sprague-Dawley rats were randomly divided into sham, UUO, UUO + enalapril, and UUO + AKF-PD groups. All rats, except sham, underwent left urethral obstruction surgery to establish

31. Spatial Dependence of Udder Surface Temperature Variation in Dairy Cows with Healthy Status and Mastitis
RESUMO Objetivou-se com essa pesquisa avaliar o padrão de variabilidade espacial da temperatura de superfície do úbere de vacas leiteiras saudáveis e com mastite. Foram selecionados 24 animais, oito saudáveis, oito com mastite subclínica e oito com mastite clínica. As imagens foram obtidas a partir de uma câmera termográfica Flir i60, resolução de

32. Benefits of physical exercise on Parkinson’s disease disorders induced in animal models
Abstract Aim: The preventive and therapeutic role of physical exercise in Parkinson’s disease (PD) has been the target of study of many scientific groups, and the research often is done in experimental models, especially rodents. Thus, the aim of this review was to analyze a database, elucidating the main benefits that the systematized practice of physic

34. Engineering biodiversity as a model for the species conservation
Abstract: Early humans have domesticated plant and animal species based on ancient empirical concepts (Darwin 1868, 1876). In 1886, Mendel established a new paradigm of hereditary laws (Mendel 1866, 1870, 1950) based on genotypic and phenotypic traits of cross-compatible species, establishing a complex breeding technology that is currently utilized for the d

35. Inbreeding depression in Holstein cattle in Brazil
ABSTRACT The objective of this study was to evaluate inbreeding depression in Holstein cows in Brazil, considering their 305-day milk production (MP), age of first calving (AFC), and calving interval (CI). The effects of inbreeding depression on the traits were determined using four regression models (linear, quadratic, exponential, and Michaelis-Menten) abo

36. Genetic parameters, genetic trends, and principal component analysis for productive and reproductive traits of Guzera beef cattle
ABSTRACT The objectives of this study were to estimate genetic parameters and genetic trends and perform principal component analysis for the following traits: body weight adjusted at 210 days of age (W210), one year (W365), and yearling or 450 days of age (W450); weight gain from birth to weaning or 210 days of age (WGBW), from weaning to 365 days of age (W
