Morfologia do figado da paca (Cuniculus Paca, Linnaeus 1766)

The elements related to the morphology of the liver of paca (Cuniculus paca), the second largest rodent of the Brazilian fauna, were observed; this species present zootechnical potential. Eight animals from the animals sector of Faculdade de Ciencias Agrarias e Veterinarias - Campus of Jaboticabal - UNESP, which is duly certified by IBAMA as an experimental breeding institute, were used. Through a dissection procedure, it was found that the liver of the paca is located in the cranial portion of the abdomen, immediately after the diaphragm, to which it is connected by the triangular, coronary, and falciform ligaments, having its bigger part located right to the medium plan. The liver of this rodent presents the following lobation: right lateral lobe, right medial lobe, quadrate lobe, left medial lobe, and left lateral lobe, besides the caudate lobe formed by the papillary process of caudate lobe and the caudate process of caudate lobe. Gallbladder is located between the quadrate and right medial lobes. Fragments of this organ were collected, fixed, and histologically prepared, being the samples analyzed through light microscopy. It was microscopically observed that intralobular connective tissue is scarce, basically it consists polyhedral hepatocytes organized into cords interposed between sinusoids and the portal triads are found in the lobe, consisting of the portal vein, hepatic artery, and biliary duct.

Morfologia macroscópica e topografia anatômica do intestino grosso da paca (Cuniculus paca Linnaeus, 1766)

Exploring the potential of using the paca as livestock involves understanding the morphophysiology of its digestive tract so its nutrition can be properly managed. The morphological and anatomical aspects of the large intestine of this species were investigated by inspecting material that was fresh and fixed in an aqueous solution of 10% formaldehyde. The material was provided by the Setor de Animais Selvagens do Departamento de Zootecnia da Faculdade de Ciencias Agrarias e Veterinarias de Jaboticabal - UNESP (FCAV - UNESP). The large intestine of the paca is formed by cecum, colon and rectum, and is located in the abdominal and pelvic cavity near the third or fourth lumbar vertebrae. It was found, in the 10 samples analyzed, that there was no change in the pattern of this arrangement and that this pattern resembles that of mammals in general.

Topografia do cone medular da paca (Agouti paca, Linnaeus - 1766)

We object in this work to determine the skeleton sintopy of the medular cone termination of the paca relating to the lumbar and sacral vertebrae, thus aiming at establishing morphometric and topographical parameters of the medular cone in this specie. We accomplished the dissection through skin incision, subcutaneous divulsion and dissection of the vertebral column dorsal region musculature, sectioning and removing the vertebrae arcs for better visualization of the spinal medulla. After the individualization of the medular cone, we registered the anatomical aspects of interest, emphasizing the basis and its apex in relation to the vertebrae, following the measuring of the region using a caliper rule; photographs and schematic drawing were made to register the findings of studied specimens.

Morfologia do intestino delgado de capivara - Hydrochoerus hydrochaeris (Linnaeus, 1766)

The high potential for the exploitation of capybara requires information about its digestory morphophysiology, to improve nutritional handling. In the present study, gross anatomy, light microscopy and body and intestine lengths of 25 capybaras were evaluated. The minimum and maximum small intestine lengths for females and males were, respectively, 441 cm and 1734 cm, and 355 cm and 1123 cm. These values position the capybara between canine and swine intestinal lengths. The ratio between small intestine and body length was 12:1, without differences between sexes. There were no statistically significant differences between sexes for each part of small intestine. Correlation between length of each small intestine segment and body length was positive, and statistically significant only for the duodenum. The small intestine wall was formed by mucosa, submucosa, muscular and serosa. The mucosa presented intestinal and duodenal glands, of mucosal and serosal types, respectively. The mucosa muscular layer consisted of two distinct layers in the jejunum and ileum, and a thin and single layer in the duodenum. The submucosa, formed by moderate dense connective tissue, didn't show glands. The fiber bundles of the internal layer of muscular tunic were helicoidally arranged. The gross anatomy of the capybara small intestine was similar to canine and swine intestines. Microscopically, however, subtle differences can be identified in the submucosa and internal muscular tunics.

Long-range and short-range dihadron angular correlations in central PbPb collisions at psNN = 2:76 TeV

First measurements of dihadron correlations for charged particles are presented for central PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76TeV over a broad range in relative pseudorapidity (Δν) and the full range of relative azimuthal angle (Δø). The data were collected with the CMS detector, at the LHC. A broadening of the away-side (Δø y≈ π) azimuthal correlation is observed at all Δν, as compared to the measurements in pp collisions. Furthermore, long-range dihadron correlations in Δν are observed for particles with similar ø values. This phenomenon, also known as the \ridge, persists up to at least jΔνj = 4. For particles with transverse momenta (pT) of 2-4 GeV/c, the ridge is found to be most prominent when these particles are correlated with particles of pT = 2-6 GeV/c, and to be much reduced when paired with particles of pT = 10-12 GeV/c.

Tendencies to explicitation in 'A Legião Estrangeira' translated into English with the tittle The Foreign Legion by Giovanni Pontiero

Some aspects involving explicitness within the literary translation process from Portuguese into English are analyzed. Clarice Lispector's 'A Legião Estrangeira' and its translation by Giovanni Ponteiro as The Foreign Legion, have been selected for current investigation employing the theoretical and methodological approach based on Baker's Corpus-based Translation Studies (1993, 1995, 1996, 2000) and Berber Sardinha's Corpus Linguistics (2004). The interrelations between the original and the translated texts and Ponteiro's solutions in his translation of preferential and recurring terms and idiomatic expressions are underscored and discussed.

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.
