13. Action of neuwiedase, a metalloproteinase isolated from Bothrops neuwiedi venom, on skeletal muscle: an ultrastructural and immunocytochemistry study
The damaging effects of neuwiedase, a non-hemorrhagic snake venom metalloproteinase from P-I class, on gastrocnemius muscle are studied herein. Following neuwiedase injection, ultrastructural alterations were detected early showing disarrangement of skeletal muscle fibers (characterized by discontinuity of Z lines), mitochondrial swelling, and disruption of

14. Arquitetura muscular e envelhecimento: adaptação funcional e aspectos clínicos; revisão da literatura
O envelhecimento é associado a um progressivo declínio na massa muscular, conhecido como sarcopenia, que afeta diretamente a arquitetura e a capacidade de produção de força muscular. O objetivo deste artigo foi revisar a literatura sobre os efeitos do envelhecimento sobre a arquitetura muscular, bem como revisar as principais evidências dos efeitos de

15. Identificação e caracterização funcional dos elementos cis-regulatorios da miostatina / Identification and functional characterization of the cis-regulatory elements of myostatin
The Myostatin protein (also known as GDF8) is a member of the transforming growth factor-β (TGF-β) superfamily and is expressed almost exclusively in skeletal muscle, both in the embryo and in the adult, where the protein circulates in the blood flow. It was initially identified in 1997 by MCPHERRON et al., and since then many studies have been dem

16. Ultra-sonografia muscular cervical e pélvica de cães da raça Golden Retriever portadores e afetados pela Distrofia Muscular e em, terapia celular / Cervical e pelvic ultrasonography of Golden Retriever dogs carrying and affected by the Muscular Dystrophy and in cellular therapy
The dogs Golden Retriever with Muscular Dystrophy (GRMD) are considered experimental models for study of the Muscular Dystrophy of Duchenne that acomete human, and they are genetically homologue. We use the muscular ultrasound to evaluate the therapeutical evolution of injection of stem cells (SC). For this experiment we use 8, being 6 affected for disease a

17. Motor Control Modeling to Entropy Generation Minimization in Peripheral Mechanical Processes / Modelagem do controle motor para minimização de geração de entropia em processos mecânicos periféricos
Objectives: Classical studies showed that the transition among gait patterns, in vertebrate locomotion, occur when there is an increase in energetic demand. Since the muscular movement is performed under central nervous system control, it is this one that determines the gait pattern in the end. Therefore, this structure is able to translate mechanical events

18. Chronic hepatitis C and fibrosis: evidences for possible estrogen benefits
The main injury caused by hepatitis C virus is the hepatic fibrosis, as a result of a chronic inflammatory process in the liver characterized by the deposit of components from the extracellular matrix. The fibrosis development leads to the modification of the hepatic architecture, of the hepatocellular function and to irregularities in the microcirculation.

19. Estudo morfuncional do mÃsculo ancÃneo atravÃs da observaÃÃo em humanos e eletroneuromiografia de superfÃcie
The anconeus, a muscle with peculiar characteristics, is scarcely mentioned in the scientific literature. It is considered by some authors a part of the triceps muscle, while other authors consider it an independent muscle. The anconeus muscle is active during the extension of the elbow, however its effective action on elbow extension is small and the tricep

20. Associação entre bruxismo do sono e dor miofascial: um estudo polissonográfico / Association Between Sleep Bruxism and Myofascial Pain: a Polysomnographic Study.
Objectives: To test 1) the association between sleep bruxism (SB) and miofascial pain (MFP); 2) the correlation between rhythmic masticatory muscle activity (RMMA) and pressure pain threshold (PPT) at morning, 3) the influence of previous tenderness over RMMA in bruxers and non-bruxers with/without MFP, and 4) the validity of a clinical diagnostic criteria o

21. "Investigações sobre o controle neuromotor do músculo reto do abdome" / INVESTIGATIONS ABOUT THE NEUROMOTOR CONTROL OF THE RECTUS ABDOMINIS MUSCLE
The rectus abdominis is an important muscle of the abdominal wall; it is responsible for the stabilization and function of the spine, as to athletic activity as daily activity. However, we do not have enough knowledge about the neuromotor control of this structure in voluntary activities, like abdominal exercises and how different tasks alter the segmental a

22. In vivo human gastrocnemius architecture with changing joint angle at rest and during graded isometric contraction.
1. Human gastrocnemius medialis architecture was analysed in vivo, by ultrasonography, as a function of joint angle at rest and during voluntary isometric contractions up to the maximum force (MCV). maximum force (MVC). 2. At rest, as ankle joint angle increased from 90 to 150 deg, pennation increased from 15.8 to 27.7 deg, fibre length decreased from 57.0 t

23. Molecular architecture of rabbit skeletal muscle aldolase at 2.7-A resolution.
The molecular architecture of the rabbit skeletal muscle aldolase (D-fructose-1,6-bisphosphate D-glyceraldehyde-3-phosphate-lyase, EC 4.1.2.13) tetramer has been determined to 2.7-A resolution. Solution of the three-dimensional structure of rabbit muscle aldolase utilized phase information from a single isomorphous Pt(CN)4(2-) derivative, which was combined

24. Detailed morphology of the tensor tympani muscle of the rat. An integrated light microscopical, morphometrical, histochemical, immunohistochemical and electron microscopical study in relation to function.
The gross anatomy, microscopical anatomy, morphometry, enzyme histochemistry, immunohistochemistry and electron microscopy of the tensor tympani muscle of the rat was studied. The aim of the study was to create an integrated insight into the morphology of the muscle and to discuss functional implications. The tensor tympani muscle of the rat is an atypical m
