1. Relationships between land use and water quality obtained for the evaluation of genotoxic effects in plant bioindicators
Resumo As atividades antrópicas bem como o uso e ocupação da terra estão intimamente ligadas à qualidade da água e do solo. Uma alternativa para avaliar suas influências na qualidade da água em corpos hídricos é através do biomonitoramento utilizando Allium cepa como organismo bioindicador. Esta técnica permite detectar anormalidades citogenétic

2. Comparison of the Incident Solar Energy and Battery Storage in a 3U CubeSat Satellite for Different Orientation Scenarios
ABSTRACT In CubeSats, because the size is limited, the estimation of the incident solar energy according to the orbital parameters and satellite attitude is more critical for the design process of the electrical power system. This estimation is helpful either for sizing of the power sources and energy storage or for defining the operation modes of the CubeSa

3. Implantation of muscle satellite cells overexpressing myogenin improves denervated muscle atrophy in rats
This study evaluated the effect of muscle satellite cells (MSCs) overexpressing myogenin (MyoG) on denervated muscle atrophy. Rat MSCs were isolated and transfected with the MyoG-EGFP plasmid vector GV143. MyoG-transfected MSCs (MTMs) were transplanted into rat gastrocnemius muscles at 1 week after surgical denervation. Controls included injections of untran

4. Effects of sciatic nerve transection on ultrastructure, NADPH-diaphorase reaction and serotonin-, tyrosine hydroxylase-, c-Fos-, glucose transporter 1- and 3-like immunoreactivities in frog dorsal root ganglion
Frogs have been used as an alternative model to study pain mechanisms. Since we did not find any reports on the effects of sciatic nerve transection (SNT) on the ultrastructure and pattern of metabolic substances in frog dorsal root ganglion (DRG) cells, in the present study, 18 adult male frogs (Rana catesbeiana) were divided into three experimental groups:

5. Células satélites e fusos neuromusculares em músculos estriados de ratos desnervados por longo período / Satellite cells and neuromuscular spindles in skeletal muscles in long term denervated rats
O músculo estriado esquelético apresenta em sua constituição células satélites (CS) que se encontram em estado quiescente localizadas entre o sarcolema e a lâmina basal das fibras musculares. As CS podem ser ativadas, diferenciando em mioblastos, contribuindo para regeneração e/ou crescimento do tecido muscular. Os Fusos neuromusculares são mecanor

6. Papel do óxido nítrico no reparo muscular
Óxido nítrico (NO) é uma molécula que exerce uma multiplicidade de funções fisiológicas importantes que vêm sendo estudadas em diversos tecidos. No entanto, o papel do NO em processos fisiológicos e patológicos no músculo estriado é pouco conhecido, apesar de algumas evidências apontarem para uma função de regulação redox e interação com c

7. Ação da laserterapia de baixa intensidade (830nm) na regeneração muscular de ratos idosos
The elderly still go through physical changes, especially musculoskeletal disorders such as sarcopenia, changes in central and peripheral nervous system, blood hypoperfusion, regenerative changes contributing to atrophy and muscle weakness, undermining the activities of daily living (AVL). The regenerative process happens about the determination, proliferati

8. Avaliação do padrão de degeneração e regeneração muscular em diferentes modelos murinos para distrofias musculares progressivas / Study of degeneration and regeneration pathways, in mice models for muscular dystrophies
The muscular dystrophies are a heterogeneous group of genetic diseases characterized by progressive and irreversible degeneration of skeletal muscles. Muscle weakness is the consequence of an imbalance between successive cycles of degeneration and regeneration, with further replacement of the degraded muscle fibers by adipose and connective tissues. Several

9. Influência das HSPs (heat shock proteins) e do mTORC-1 (mammalian target of rapamycin complex 1) na regeneração de músculos esqueléticos. / Influence of HSPs (heat shock proteins) and mTORC1 (mammalian target of rapamycin complex 1) in skeletal muscle regeneration.
The goal of this work was to contribute to a better understanding about the intracellular mechanisms involved in skeletal muscle regeneration by studying the influence of heat shock proteins (HSPs) and mTORC1 (mammalian target of rapamycin complex 1) in the muscle regeneration process. The treatment with radicicol (a HSP inductor) in injured muscles induced

10. Efeitos do treinamento resistido associado com decanoato de nandrolona sobre a expressão gênica de moduladores de vias de hipertrofia e atrofia do músculo esquelético
Androgenic-anabolic steroids (AAS) are spread among athletes and no athletes in order to improve performance or physical appearance. AAS targets the satellite cells in skeletal muscles, which are the major precursors of the skeletal muscle, and are essential for muscle growth and repair. When activated, in the presence of several factors, including myogenic

11. Diversity among satellite glial cells in dorsal root ganglia of the rat
Peripheral glial cells consist of satellite, enteric glial, and Schwann cells. In dorsal root ganglia, besides pseudo-unipolar neurons, myelinated and nonmyelinated fibers, macrophages, and fibroblasts, satellite cells also constitute the resident components. Information on satellite cells is not abundant; however, they appear to provide mechanical and metab

12. Características clínicas de 64 indivíduos portadores de uveítis posterior activa presumiblemente toxoplásmica en Pernambuco
PURPOSE: To describe clinical characteristics of posterior active uveitis presumptively by Toxoplasma gondii (PAUPT) in patients with typical lesion. Tranversal study. METHODS: Sixty-four patients with retinochoroiditis scatter and active satellite lesions examined in Pernambuco, Brazil. All were older than 10 years and immunocompetent. Gender, age, skin col
