Efeitos do treinamento resistido sobre secreação de testosterona e cortisol: uma revisão bibliográfica

You can set the resistance training such as making a move against a resistance by performing a muscle contraction and generating a muscular adaptation. This form of training, was initially used only in training athletes aiming to strengthen and improve fitness. Some coaches did not give proper focus, as the increase in muscle mass would cause loss of flexibility and agility. But over time a huge evolution occurred within this area and the practitioners of resistance training are no longer just athletes, and reached the whole community, from young to elderly, being a physical activity that generates a large caloric expenditure and has several health benefits, improve the cardiovascular system and decreasing the amount of body fat in the body. Cortisol is a hormone secreted from a stressful stimulus to the body, secretion undergoes control of the hypothalamic-pituitary axis, which releases the hormone into the bloodstream andrenocorticotrópico, going to the adrenal cortex responsible for their release. This has catabolic function, acting in the metabolism of carbohydrates, proteins and lipids, as well as having an important effect antiflamatório. Testosterone is a steroid hormone cholesterol from being produced by the testicles in men, as in women is produced to a lesser extent in ovary and adrenal glands, has functions androgenic and anabolic. Androgen function is responsible for the development of male sexual characteristics, while on anabolic function operates in the growth of muscles and bones, influencing the development of the human body organs. Within the metabolic changes that occur in the resistance training testosterone plays an important role in protein synthesis, influencing the production of strength and / or power during exercise. The objective of this work is through a literature review to assess the effects of resistance training on the production of these hormones and the relationship between them

Microbialitos da formação Codó (Aptiano Superior) às margens do rio Tocantins em São Miguel do Tocantins (TO)

The southwestern region of the São Luís-Grajaú Basin has a rare outcrop of the Codó Formation (upper Aptian) with seven outstanding microbialite bioherms along the left margin of the Tocantins river, near Imperatriz (MA). Resting on sandstones of the Grajaú Formation, the Codó Formation presents: 1) a 20 cm thick basal calcilutite with gypsite pseudomorphs and some fossil tree stems; 2) metric dark shales with carbonate nodules and thin intercalated carbonate layers, enclosing some microbial laminites; 3) a 2 cm thick upper breccia composed of microbialite fragments and other carbonate clasts, with halite hoppers on the top; 4) the carbonate bioherms, which partially overlie the extensive shales and interrupt them laterally, as well as the breccia. The bioherms in the northern part of the outcrop are thicker (<2 m) and have interbedded dark shales, whereas the southern are thinner and continuous in the vertical direction. In general, they are composed of irregular gently to strongly wavy microbial laminites, sometimes with pseudocolumnar to conical lamination. All microbialites with highest synoptic relief (<20 cm) look like columnar stromatolites on weathered lateral expositions. In plan view, the horizontal sections of these microbialites are circular to slightly elliptic, sometimes forming very small channels (N60W) filled with fine breccia. The highest bed of the northern bioherm has mixed microbial laminites and columnar stromatolites, where intercolumnar spaces were filled with microbialite clasts, fish bones, plant fragments and very small probable crustacean coprolites. Several fractures and deformation in this upper bed indicate an initial brecciation process probably caused by subaerial exposure. In microscopic scale, the lamination is smooth, diffuse, defined by subtle granulation differences of very fine granular calcite crystals within micrite, but oxide levels, dissolution surfaces or thin precipitated calcite veneers...

A análise morfométrica para avaliar a taxa de progressão da fibrose hepática na hepatite C crônica após o transplante renal: uma série de casos

The real role of renal transplantation in hepatic fi brosis progression caused by hepatitis C virus is still unpredictable. Histological evaluation of the liver is the best form to estimate fi brosis evolution, although semiquantitative analysis carries important limitations. Objective: To apply a morphometric quantitative assay on hepatic fi brosis progression in renal recipients with hepatits C. Methods: Thirty patients were initially evaluated, but only seven were included. They underwent the fi rst biopsy near the transplantation date and the second biopsy at least 4 years later. The immunosuppressant therapy adopted in all cases was azatioprine and micofenolate. Fibrosis progression rate (FPR) was calculated before and after the surgery date in each patient according to Metavir score and morphometric analysis. Results: The FPR calculated by Metavir score showed no statistical difference between pre- and post-transplantation (p=0.9). The FPR calculated by the morphometric analysis was 0.58 ± 0.78 before transplantation and 3.0 ± 3.3 after the surgery, with statistical signi- fi cance between these values (p=0.0026). Conclusion: In the sample assessed, the progression of hepatic fi brosis was documented and quantifi ed only by the morphometric analysis, which is as a promising approach to histological evaluation of these patients.

Pancreatic hemangioma manifesting as variceal gastroesophageal bleeding during pregnancy: case report

There are only 10 reported cases of pancreatic hemangiomas in adults, only one of them causing digestive bleeding. We present a case of variceal bleeding and portal hypertension caused by a pancreatic hemangioma. The patient had 19 year-old and was received at her 16th week of pregnancy. She had massive hematemesis, controlled after variceal band ligation. Her image exams revealed a cystic lesion of 164 cm³ in the pancreas tail and signs of portal hypertension. Two months after, the ultrassonographic exam documented the lesion growth, achieving 200 cm³ at that time. The patient was submitted to distal pancreatectomy, and the histopathological analysis revealed a pancreatic hemangioma of 11 x 9 x 8 cm. Therefore, we report the second case of digestive bleeding caused by a pancreatic hemangioma, which had a well documented growth during the pregnancy. Additionally, we review the previous reports of pancreatic hemangiomas and discuss the hypothesis of hormonal infl uence on the natural history of these tumors.

Hanseníase virchowiana: comprometimento medular

Paciente feminino 36 anos, com queixa de febre noturna, astenia, parestesia de membros inferiores, artralgia, hepatoesplenomegalia, lesões cutâneas, anemia hipocrômica, microcítica e linfopenia. Sorologia negativa para Hepatite B,C e HIV; FAN e anti-DNA também negativos. Histopatologia da medula óssea mostrou-se discretamente hipercelular, com presença de focos de histiócitos com citoplasma vacuolado (células pseudo-gaucher-like),aspecto megaloblástico, linfoplasmocitico e lipogranulomatoso. A coloração Ziehl- -Nielsen positivo; diagnóstico morfológico: micobacteriose de medula óssea. A cultura do sangue e do aspirado de medula óssea foi negativo para M.tuberculosis. Biópsia das lesões cutâneas máculas e pápulas hipercrômicas dos membros inferiores e superiores revelou hanseníase de padrão Vichowiana. A pesquisa BAAR pela Faraco demonstrou numerosos bacilos, sendo a maioria de padrão granuloso. Pacientes com hanseníase virchowiana tem acometimento cutâneo em 100% dos casos, o baço é o órgão mais frequentemente acometido com disseminação através do sangue periférico. O quadro anêmico e a linfopenia provavelmente se deve à cronicidade da infecção, levando a infiltração medular. A ocorrência do comprometimento medular em paciente com hanseníase Virchowiana é excepcional, mesmo em países endêmicos, e pode indicar necessidade de tratamento mais prolongado.

O seguimento da sífilis congênita em crianças tratadas ao nascer

Purpose: Describe the initial clinical management and therapeutic monitoring dispensed for newborns diagnosed with congenital syphilis at birth and as of the high public hospitals in the Federal District, Brazil. Methods: Collected informations from the initial clinical management and continuity of care accorded to 81 newborns diagnosed with congenital syphilis reported to the National System of Diseases of Notification in 2008. Results: The hemogram occurred in 46.9%, and radiological long bone in 81.4%. Four children (4.9%) followed up according to the protocol of the Ministry of Health in relation to bi-monthly follow- -up until 12 months of age was 93.8% of cases ignored and found no record of complete follow-up at 18 months old of age. Conclusions: The initial clinical management and therapeutic follow-up of newborns with congenital syphilis in the Federal District is not carried out adequately and does not accordance with the guidelines set by the Ministry of Health.

Características fenotípicas do nanismo em pôneis neonatos: relato de casos

Three newborn Mini-Horses and one Brazilian Pony horses were presented to the Veterinary Hospital with phenotypic appearance of dwarfism. They had relatively larger head conformation, occlusive dental defect and musculoskeletal changes such as abnormal short limbs and deformation on the third metatarsal bone. The radiographic examination showed abnormal growth plates on femoral condyle and proximal thirds metatarsal bones. Due to the high possibility of future complications and quality of life loss, the animals were euthanized. We emphasize the importance of recognition of phenotypic changes related to dwarfism in horses, enabling the phenotypic diagnosis can direct crossings for nontransmission of this abnormality as genetic inheritance.

Lissencefalia em cães e gatos: revisão

Lissencephaly is a condition characterized by a lack of cerebral convolutions and sulci, which results from defective migration of nervous cells precursors in the telencephalus. The cause is presumably genetic. Lhasa-Apso dogs are most frequently affected, even though it may also occur in association with cerebellar hypoplasia in the Irish Setter, Wire-Haired Terrier and Samoieda breeds. This association was also reported in a cat. Clinical signs consist of dementia, aggressiveness, seizures, visual and olfactive dysfunctions, slow postural reactions and reduced menace response. Definitive diagnosis requires exams such as magnetic resonance imaging, cerebral biopsy or necropsy. There is no specific therapy for this disease, and seizures must be treated with anticonvulsants. The aim of this study is to review the literature regarding lissencephaly.

Proporção tecidual da perna de caprinos jovens em função do grupo racial, peso de abate e sexo

To evaluate the effect of breed group, slaughter weight and sex on tissue proportion of the leg and muscle, bone and fat ratio in confined kids, seventy-four goats of both sex were used and divided among breed groups: Alpine (A), ½ Nubian + ½ Alpine (½ ANA), ½ Boer + ½ Alpine (½ BA), ¾ Boer + ¼ Alpine (¾ BA) and ½ Nubian + ¼ Alpine + ¼ Boer, (Three cross - TC), at three slaughter weights (25, 30 and 35 kg). Leg represented 31.01% of half carcass, where 62.29% was total muscle, 21.45% total bone and 8.35% total fat. Alpine animals had higher bone weight than other groups. Male kids had higher muscle and bone proportion, whereas females had higher subcutaneous and intramuscular fat in leg. The percentage of total weight of the muscle, five muscles, adductor muscle, quadriceps muscle and femur were higher in the slaughter weights of 25 and 30 kg.

Densidade mineral óssea de perus de corte vacinados e não vacinados contra coccidiose

It was evaluated bone mineral density of turkeys submitted the vaccination against coccidiosis. Used 420 turkeys of one day, divided in 4 treatments with 5 repetitions: T1 – control diet; T2 - diet and anti coccidiosis drugs; T3 - diet and commercial vaccine; T4 - diet and recombinant vaccine. To the 28 days the birds had been submitted to the challenge of coccidiosis, carried through inoculation of oocisty talked back directly in the esophagus of the birds. The bone quality was evaluated to the 21, 35, 49 and 72 days of age. For this, 8 birds for treatment had been collected, in each age of collection that had been sacrificed by cervical displacement. The tibiae and femura had been radiographed and tomographed for evaluation of the bone density, had been later evaluated texts of dry substance, bone ashes, calcium and of phosphorus. It had differences only between the ages, being that the treatments had not caused alterations of the bone characteristics. To the 56 days the birds had presented bone quality worse. The treatments had not influenced the studied parameters. What it allows to conclude that the vaccination against coccidiosis promotes good mineralization of the bones.

Características do processo de diagnóstico de hanseníase no atendimento primário e secundário

Contexto e objetivo: A hanseníase caracteriza-se por ter diagnóstico eminentemente clínico, principalmente através da constatação de hipo ou anestesia das lesões, ou seja, sem necessariamente o uso de exames adicionais, como baciloscopia e biópsia, utilizados para classificação clínica da doença. Buscou-se definir se há tendência à desvalorização da avaliação clínica em favor do excesso de exames complementares, investigar a adequação do registro nos atendimentos da atenção básica e compará-los com o obtido em serviço de média complexidade. Desenho e local: Estudo transversal, de base populacional, utilizando registros de prontuários, realizado em dois âmbitos de atendimentos de saúde da cidade de Campinas (SP): os Centros de Saúde e a assistência dermatológica especializada de hospital de ensino. Métodos: Os registros foram investigados por meio da aplicação de checklist, contendo itens indispensáveis ao atendimento a hansenianos. Associações foram testadas pela prova de Goodman e ao nível de 5% de significância. Resultados: Foram avaliados 33 prontuários oriundos dos centros de saúde e 36 do hospital, observou-se polarização entre registros adequados e ausentes, evidenciando a presença de efeito tudo ou nada nos atendimentos; de 26 variáveis, apenas em 5 (19,23%) obteve-se predomínio da avaliação do hospital sobre os centros de saúde; evidenciou-se dependência de exames complementares, solicitados em 67 dos 69 atendimentos (97,10%), para diagnóstico da doença. Conclusão: Confirmou-se, neste estudo, déficit da avaliação médica e indicação inadequada de exames adicionais. Por associar-se com excesso de solicitação de exames, a observação clínica mostrou-se incompleta, comprometendo a capacidade diagnóstica dos atendimentos a hansenianos.
