Efeito da Densidade de Estocagen na Sobrevivência e Crescimento do Pampo

Com o intuito de conhecer o potencial zootécnico do pampo, foi avaliado o efeito de diferentes densidades de estocagem (100 e 200 peixes/m3) na sobrevivência e crescimento do pampo amarelo (Trachinotus carolinus), criado em tanque-rede instalado em ambiente marinho. Peixes com aproximadamente 1,0 a 2,0 g, capturados em arrastos nas praias rasas do município de Ubatuba, S.P., foram transportados ao Núcleo de Pesquisa e Desenvolvimento do Litoral Norte – Agência Paulista Tecnológica do Agronegocio – Secretaria da Agricultura e Abastecimento e mantidos durante 45 dias em tanques-rede de 5mm de malhagem. Após seleção manual, animais de 4,0 ± 0,17g foram estocados, nas densidades de 100 e 200 peixes/m3, em tanques-rede de multifilamento com 2 x 2 x 1,5m e 12 mm de malhagem, fixos a um “deck” flutuante (6,0 x 8,0 m), instalado diretamente no mar a profundidade de aproximadamente 3,5 ± 0,5 m. Os animais foram alimentados duas vezes ao dia até a saciação com ração de 40% de PB. Após 120 dias, as taxas de sobrevivência média observadas foram 77,23% e 73,11%; pesos médios (52,79 ± 4.86 g e 52,64 ± 5.64 g); Ganho de Peso (GP) (48,69 ± 4,05 g e 48,73 ± 4,00 g); Taxa de Crescimento Especifico (TCE) (2,13 ± 1,24 e 2,16 ± 1,03) e Conversão Alimentar Aparente (CAA) (3,23 ± 1,52 e 2,66 ± 0,78), respectivamente para 100 e 200 peixes/m3. Estes dados não apresentaram diferenças significativas (P 0,05) entre os tratamentos testados. Entretanto os ganhos de peso do pampo, no presente experimento foram superiores a muitos trabalhos encontrados na literatura, o que nos leva a concluir que a densidade de 200 peixes/m3, utilizada neste estudo, pode ainda estar abaixo da capacidade de suporte para a espécie e pode ser o ponto de partida para futuros estudos, considerando o estágio de desenvolvimento dos animais

Integração ensino/serviço/comunidade: a extensão como constituinte orgânica da formação universitária

This experience report introduces the concept of extension of a project of the Federal University of Paraná, entitled "Integrating Teaching / Service / Community in SUS", as a component of the tripod teaching / research / extension, inseparable constituents of the training process. Based on this understanding, it describes the activities and attempts to demonstrate coherence of practical action with its theoretical basis. The project begins with the evaluation of health services in primary care at the Brazilian Governmental Health System, as well as with the identification of problems, formulation of proposals for solutions and implementation of changes in services aiming at their improvement. Such actions provide a learning process for students and health workers which begins with the syncretic representation of reality, goes through moments of abstraction and returns to reality in a movement of integrating synthesis, facilitating understanding of phenomena beyond their appearance, reaffirming the reality as a truth criterion of produced knowledge. The users are also benefited by better understanding of reality and by the improvement of care services provided by health teams, resulting from this movement. Experiences have been documented and disseminated through presentations at scientific events and publications of articles in periodicals.Este relato de experiencia presenta el concepto de extensión de un proyecto de la Universidad Federal del Paraná, titulado "Integración de Enseñanza / Servicio /Comunidad en el SUS ", entendida como un componente del   trípode enseñanza / investigación / extensión, elementos inseparables del proceso de capacitación.

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

Tumor neuroendócrino em coração de cão: Relato de caso.

Background: Neuroendocrine tumors are epithelial tumors with predominant neuroendocrine differentiation. Ectopic thyroid carcinoma develops in the ectopic thyroid parenchyma, in the anterior mediastinum, being an important differential diagnosis of paraganglioma, although occurring less frequently than the same. The cells invade the mediastinal fat reaching the adventitia of the aorta. There is a possibility of metastatic formations in the lung, kidneys, and pancreas. A supporting treatment was provided. The present study proposes the exposition and description of a case of neuroendocrine tumor in the heart, considering the rarity of the involvement of this tumor in the canine species.Case: A 9-year-old American Bulldog male canine was treated at home in the city of Rio de Janeiro. On clinical examination, dyspnea, edema of the hind limbs and an increase in abdominal volume were observed. With the suspicion of congestive heart failure, mainly on the right, cardiac exams were requested. Because it was an aggressive animal, sedation was performed with a combination of tiletamine and zolazepam. During cardiac auscultation, the presence of S4 was noticed, characterizing a gallop rhythm. No alterations were observed on the electrocardiographic examination. The echocardiogram showed a tumor mass in the atrium and dilation of the venous return vessels. The tumor enveloped 80% of the atrium of a 9-year-old male American Bulldog. The abdominocentesis procedure was performed to drain abdominal free fluid. Furosemide, enalapril and digoxin were prescribed as a treatment. Three months after the start of treatment, the animal presented intense dyspnea that culminated in the death of the patient, who later had the body sent for necropsy and subsequent tissue collection for histopathological analysis. Based on the immunohistochemical markers chromogranin and synaptophysin, the work here presented describes a case of a neuroendocrine tumor suggestive of paraganglioma involving a dog’s heart.Discussion: Brachycephalic dogs, such as Boxers, Bulldogs and Boston Terriers, are predisposed to the development of paragangliomas. The genetic predisposition is related to hyperplasia of the carotid bodies generated by chronic hypoxia, resulting from obstructive processes in the airways. As the reported dog is an American Bulldog, the possibility of the tumor in question was reinforced. Paragangliomas are more frequent in males from nine to thirteen years of age, commonly associated with other endocrine neoplasms. It is also an important marker present in paragangliomas. In contrast to the literature, the report points to a neuroendocrine tumor suggestive of paraganglioma, without eliminating the possibility of an ectopic thyroid tumor, because although TTF-1 appears in most thyroid tumors, not all of them are present, although it is very suggestive. Treatment in question, attributed to the control of right congestive heart failure, although with little effect, denotes that the obstructive process of the return pathway, even with the use of drugs that prevent congestion, did not delay the evolution of the disease. However, it is observed that the treatment resources for these tumors, whether by surgical or chemotherapy option, also have few answers. The lack of literature on ectopic thyroid tumors influences the diagnosis of paraganglioma. Thus, clinical and complementary findings, mainly along with immunohistochemistry, were essential in the diagnosis of neuroendocrine tumor. After 3 months of the start of the treatment, the animal died. Keywords: heart base tumor, Immunohistochemical diagnosis, heart, dog.
