14. Expressão dos fatores de regulação miogenica e de cadeia pesada da miosina no musculo estriado esquelitico da tilapia do Nilo (Oreochromis niloticus) durante o crecimento / Miogenic regulatory factors and myosin heavy chain expression in the striated skeletal muscle of the Nile tilapia (Oreochromis niloticus) during growth
Nos peixes, o conhecimento dos fatores que controlam o crescimento muscular e a análise das proteínas miofibrilares, é importante para entender a dinâmica do crescimento, a plasticidade e as adaptações musculares, principalmente, em espécies com grande valor comercial como a tilápia do Nilo (Oreochromis niloticus). No presente estudo, utilizou-se a t

15. Disposition of the striated urethral sphincter and its relation to the prostate in human fetuses
OBJECTIVE: To describe the arrangement of the muscle fibers of the striated urethral sphincter and its relationship with the prostate during the fetal period in humans. MATERIALS AND METHODS: We analyzed 17 prostates from well preserved fresh human fetuses ranging in age from 10 to 31 weeks postconception (WPC). Transversal sections were obtained and stained

16. Structural analysis of gubernaculum testis in cryptorchid patients submitted to treatment with human chorionic gonadotrophin
OBJECTIVES: To make a histological and stereological analysis of gubernaculum testis elastic system fibers, collagen and striated muscle cells in patients with cryptorchidism treated with human chorionic gonadotrophin (hCG). MATERIALS AND METHODS: Gubernacula tissue samples were obtained from 12 patients with cryptorchidism. Patients' ages ranged from 1 to 3

17. Composição de fibras musculares esqueléticas de eqüinos jovens da raça Brasileiro de Hipismo
The aim of this study was to typify the skeletal striated fibers of the gluteus medius muscle of young Brasileiro de Hipismo (BH) horses by means of histochemical analysis with m-ATPase and NADH-TR according to the sex and the biopsy depth. It was observed that the frequency (F;%) and the relative cross sectional area (RCSA;%) of the fibers type IIX were gre

18. Avaliação comparativa das alterações morfológicas nas células musculares estriadas em cães Golden Retriever acometidos e não acometidos por distrofia muscular do tipo Duchenne / Comparative evaluation of the morphological changes in skeletal muscular cells of Golden Retriever suffers and non-suffers of muscular Dystrophy
A musculatura estriada de cães Golden Retriever, jovens e adultos, provenientes do Canil GRMD-Brasil, foram analisadas sob microscopia de luz. Para tanto, foram coletadas amostras do músculo bíceps femoral de um cão adulto não-acometido e um acometido por distrofia muscular, e dos músculos bíceps femoral, semitendinoso, diafragma e miocárdio ventricu

19. Effects of immobilization and aquatic rehabilitation on the mechanical properties of gastrocnemius muscle of trained and sedentary female rats / Efeitos da imobilização e reabilitação aquática em propriedades mecânicas do músculo gastrocnêmio de ratas treinadas e sedentárias
The skeletal muscle is a very adjustable structure and may present changes in response to functional demands. The aim of this study was to investigate the influence of physical training (swimming), sedentarism and the effects of immobilization and aquatic rehabilitation on the mechanical properties of the gastrocnemius muscle of trained and sedentary rats.

20. Dermatomyositis: analysis of 109 patients surveyed at the CHSPU / Dermatomiosite: estudo de 109 pacientes avaliados no HCFMUSP
Dermatomyositis is a chronic idiopathic inflammatory disorder which affects the striated skeletal muscles, the skin, and other organs. This present study aims at characterizing the patients who have been affected by this disease and were under treatment at HCFMUSP from January, 1992 to December, 2002 Its classification, the cutaneous and systemical manifesta

21. A infecção murina pelo clone Sylvio X10/4 de Trypanosoma cruzi: um modelo para estudo da patogenia da doença de Chagas crônica. / The murine infection with the Sylvio X10/4 clone of Trypanosoma cruzi: a model to study the phatogenesis of chronic Chagasdisease.
This work describes a novel murine model of the chronic infection by T. cruzi using the clone Sylvio X10/4. The infection in the C3H/HePAS mouse strain is characterized by intense inflammatory lesions in the heart, which can be comparable to the observed in the human Chagasdisease. Moderate striated muscle lesions are also present in C3H/HePAS mice. In the h

22. Esophageal striated muscle contractions in patients with Chagas' disease and idiopathic achalasia
Chagas' disease causes degeneration and reduction of the number of intrinsic neurons of the esophageal myenteric plexus, with consequent absent or partial lower esophageal sphincter relaxation and loss of peristalsis in the esophageal body. The impairment of esophageal motility is seen mainly in the distal smooth muscle region. There is no study about esopha

23. Construção e análise de mutantes fluorescentes da troponina I / Construction and analysis of fluorescent mutants of troponin I
Vertebrate striated muscle contraction is regulated by troponin (Tn). Tn is composed of three subunits: troponin I (TnI), troponin C (TnC) and troponin T (TnT). TnI has an inhibitory role that is neutralized by calcium binding to the regulatory sites in the N-domain of TnC, and TnT positions the troponin complex on the thin filament. In order to follow the C

24. A comparative study of aging of the elastic fiber system of the diaphragm and the rectus abdominis muscles in rats
In the present study the age-related changes of the striated muscle elastic fiber system were investigated in the diaphragm and rectus abdominis muscles of 1-, 4-, 8- and 18-month-old rats. The activation patterns of these muscles differ in that the diaphragm is regularly mobilized tens of times every minute during the entire life of the animal whereas the r
