1. Evaluation of the proteomic profiles of ejaculated spermatozoa from Saanen bucks (Capra hircus)
Abstract The Saanen goat breed has been widely explored in breeding programmes; however, there are few reports about the breed’s genetic and molecular composition. Thus, this study aimed to characterize the proteomic profile of spermatozoa from Saanen breeding goats. Five breeding animals with proven fertility were selected, the spermatozoa were collected,

2. Importance of Genetic Testing in Dilated Cardiomyopathy: Applications and Challenges in Clinical Practice
Resumo A miocardiopatia dilatada (MCD) é uma síndrome caracterizada por dilatação ventricular esquerda e disfunção contrátil, sendo considerada a causa mais comum de insuficiência cardíaca em adultos jovens. O uso do sequenciamento de nova geração tem contribuído com a descoberta de uma grande quantidade de dados genômicos relacionados à MCD, i

3. Antitumoral effects of Amblyomma sculptum Berlese saliva in neuroblastoma cell lines involve cytoskeletal deconstruction and cell cycle arrest
Resumo As propriedades antitumorais de extratos de glândulas salivares de carrapatos ou proteínas recombinantes foram relatadas recentemente, mas pouco se sabe sobre as propriedades antitumorais dos componentes secretados da saliva. O objetivo deste estudo foi investigar o efeito in vitro da saliva bruta do carrapato duro Amblyomma sculptum sobre as linha

4. Cardiac protein expression patterns are associated with distinct inborn exercise capacity in non-selectively bred rats
In the present study, we successfully demonstrated for the first time the existence of cardiac proteomic differences between non-selectively bred rats with distinct intrinsic exercise capacities. A proteomic approach based on two-dimensional gel electrophoresis coupled to mass spectrometry was used to study the left ventricle (LV) tissue proteome of rats wit

5. Morphology and histochemistry of glandular trichomes in Hyptis villosa Pohl ex Benth. (Lamiaceae) and differential labeling of cytoskeletal elements
ABSTRACT Lamiaceae contains many species known for their aromatic properties that are produced by the production of essential oils in glandular trichomes. Hyptis is one of the most common genera of Lamiaceae in the Brazilian flora, and includes several species with medicinal value. However, studies on the morphology and functioning of their glandular trichom

6. JVG9, a benzimidazole derivative, alters the surface and cytoskeleton of Trypanosoma cruzi bloodstream trypomastigotes
Trypanosoma cruzi has a particular cytoskeleton that consists of a subpellicular network of microtubules and actin microfilaments. Therefore, it is an excellent target for the development of new anti-parasitic drugs. Benzimidazole 2-carbamates, a class of well-known broad-spectrum anthelmintics, have been shown to inhibit the in vitro growth of many protozoa

7. Expressão das proteínas citoesqueléticas actina e tubulina em células osteogênicas cultivadas sobre vidro e vitrocerâmica bioativos / Expression of the cytoskeletal proteins actin and tubulin in osteogenic cells cultured on bioactive glass-based surfaces
Bioactive glasses and glass-ceramics have been successfully applied in various therapeutic strategies to promote the formation of mineralized matrix in bone defects. The exposure of these materials to biological fluids results in chemical and topographical modifications that may affect the interactions of cells with the biomaterial surface, with potential ef

8. Electron paramagnetic resonance study of lipid and protein membrane components of erythrocytes oxidized with hydrogen peroxide
Electron paramagnetic resonance (EPR) spectroscopy of spin labels was used to monitor membrane dynamic changes in erythrocytes subjected to oxidative stress with hydrogen peroxide (H2O2). The lipid spin label, 5-doxyl stearic acid, responded to dramatic reductions in membrane fluidity, which was correlated with increases in the protein content of the membran

9. Prokaryotic cells: structural organisation of the cytoskeleton and organelles
For many years, prokaryotic cells were distinguished from eukaryotic cells based on the simplicity of their cytoplasm, in which the presence of organelles and cytoskeletal structures had not been discovered. Based on current knowledge, this review describes the complex components of the prokaryotic cell cytoskeleton, including (i) tubulin homologues composed

10. Clinical course of 63 children with hereditary spherocytosis: a retrospective study
BACKGROUND: Hereditary spherocytosis (HS) is an inherited hemolytic anemia that is caused by deficiency or dysfunction of erythrocyte cytoskeletal proteins. AIM: The aim of this study was to describe the clinical course of hereditary spherocytosis in patients treated in the Pediatric Hematology Unit, Hospital das Clínicas, Universidade Federal de Minas Gera

11. ARHGAP21 inibe a secreção de insulina estimulada por glicose através da modulação aa FAK, CDC42 E PKC dzeta / ARHGAP21 inhibits glucose-stimulated insulin secretion through through FAK, CDC42 and PKC dzeta
Background/Aims: ARHGAP21 is a Rho-GAP that promotes activation of the Rho-GTPase Cdc42 intrinsic factor, which is responsible for the hydrolysis of GTP to GDP and those proteins inactivation. ARHGAP21 associates with PKC? in cardiomyocytes and to the C-terminal portion of FAK in glioblastoma, inhibiting Rho-GTPases and actin cytoskeleton rearrangement. Cdc4

12. Efeitos da administração intraestriatal aguda de ácido quinolítico sobre o citoesqueleto de células neurais de ratos
In the present study we investigated the effect of in vivo intrastriatal injection of quinolinic acid (QA) on rat cytoskeleton proteins in astrocytes and neurons of young rats at early stages (30 min) after infusion. Intrastriatal QA injection is an excitotoxic model of Huntington´s Disease (HD). Results showed that QA (150¿mol/0.5¿L) significantly increa
