Desempenho e morfometria duodenal de frangos de corte submetidos a diferentes níveis de energia e programas de alimentação de 42 a 57 dias de idade

This experiment was conducted to evaluate the use of different energy levels and amino acid recommendations on performance, carcass yield and intestinal morphometry of broilers from 42 to 57 days of age. We used 1,600 one-day old male broilers (Cobb 500) in a completely randomized design arranged in a 2x4 factorial scheme with 3,200 and 3,600 kcal ME/kg and four different feed programs. The metabolizable energy levels and the feed programs did not determine significant differences in carcass characteristics for choosing a level of energy or a feed program, thus the energy level and the recommendations of amino acids that determine the highest cost-benefit ratio should prevail. It was observed that 3,600 kcal ME/kg resulted in some improvement on performance and morphometry of the intestinal mucosa, also the fractioning of digestible amino acid requirements during two periods resulted in worse performance and intestinal villi height.

Aprendizado de máquina simbólico e técnicas fractais para caracterizar rejeição em biópsia miocárdica

This work combines symbolic machine learning and multiscale fractal techniques to generate models that characterize cellular rejection in myocardial biopsies and that can base a diagnosis support system. The models express the knowledge by the features threshold, fractal dimension, lacunarity, number of clusters, spatial percolation and percolation probability, all obtained with myocardial biopsies processing. Models were evaluated and the most significant was the one generated by the C4.5 algorithm for the features spatial percolation and number of clusters. The result is relevant and contributes to the specialized literature since it determines a standard diagnosis protocol. © 2013 Springer.

Morfologia, ultraestrutura e morfometria do tegumento da paca (Cuniculus paca Linnaeus, 1766) criada em cativeiro

Considering the lack of detailed information about the morphology of paca, which is the second largest rodent of Brazilian's fauna, with excellent meat quality and, due to the importance of the common integument, we described the morphology, ultrastructure and morphometry of the skin of eight pacas (Cuniculus paca), males and females, through comparative analysis of skin's segments of the cervical, dorsal and medial carpal portions. Macroscopic characteristics of the coat were studied. Part of the segments of cutaneous regions was analyzed by light microscopy, and the other part by scanning electron microscopy. We measured the thickness of dermis, epidermis, stratum corneum, the profiles of the collagen fibers of reticular dermis and the area of filled sebaceous gland cells. The results were analyzed by descriptive statistics and T test (p<0.001). The color of the coat is reddish brown with bristles arranged in groups. The architecture of the skin and skin appendages resembles those of mammals in general, although there are no sweat glands. According to the morphometric analysis, this study shows differences of the skin architecture between male and female pacas and also between various body regions in the same animal.

Estrutura, ultraestrutura e morfometria da veia cava de paca (Cuniculus paca Linnaeus, 1766) criada em cativeiro

The paca (Cuniculus paca) is the second largest rodent of the Brazilian fauna. The excellent meat quality of this specie encourages the development of their commercial production. Moreover, this animal can become a viable alternative for animal experimentation although there exists scarce detailed information concerning their morphology. Therefore the purpose of this study is to describe the morphology, morphometry and ultrastructure in segments of the cranial and caudal portions of vena cava in four adult males and females of Cuniculus paca from the squad of Wild Animals Sector of Animal Science Department of FCAV-Unesp. Parts of the segments were examined by light microscopy and part by scanning electron microscopy. Thickness measures of the tunica intima and media complex and tunica adventitia of the vena cava were taken and analyzed using T test (p<0.05). In vena cava the thickness values of the intima, media and adventitia, for all animals, were significantly higher in the cranial segment. The layers of the vessel walls showed variations in structure and thickness, presumably due to an adaptation to functional demand.
