The present study encompassed 133 participants, divided into four groups, who performed 16 weeks of resistance training, aerobic training and muscular endurance training, in addition to the control group that did not perform any practice. The GDLAM protocol was used to assess functional autonomy, and the WHOQOL-OLD questionnaire was used to assess the quality of life. After analysing the results, it was found that despite the positive effects for all experimental groups, the resistance training group was more efficient in reducing the time to perform functional autonomy tests (∆% -22.5876, p< 0.0001). Regarding the quality of life, the same group presented a significant difference for domain 6, which deals with intimacy, raising the overall quality of life of individuals (∆% 11.96531, p< 0.0001). It was concluded that resistance training showed a higher rate of improvement in functional autonomy and quality of life of the elderly. However, it would be imprudent to rule out the positive effects provided by the other training analysed. In this sense, the findings of this study reinforce the regular and oriented practice of physical exercises of different types for the elderly, being an important and decisive tool in the maintenance and improvement of multiple health variables

Título: Evaluation of induced Biological effects in rats by contiunuous and natural gamma radiation using a physical simulator Autor(es): COUTINHO, João V.S. http://lattes.cnpq.br/6600915137024415 https://orcid.org/0000-0003-3128-8767; FERREIRA, Priscila Santos; SOARES, Jacyra; PASSAMAI JUNIOR, Luis; ORLANDO, Marcos Tadeu D'Azevedo; GOUVEA, Sonia Alves Abstract: Purpose: The effects of radioactivity on human health have been debated for many years but there are still important gaps that need to be addressed especially related to the effects of high natural background radiation on the local population. The beach of Meaípe, in the city of Guarapari (Brazil), emits natural gamma radiation due to the presence of monazite sands. We aimed to investigate the effects of gamma radiation doses on the biological system of wistar rats using a physical simulator of gamma radiation designed using Meaípe monazite sands. Methods: Female Wistar rats were divided into three groups, submitted to no radiation (control group) and to continuous radiation levels, one of very high level (20 μSv h-1) and another of high level (3.6 μSv h1 ). The three group of animals were monitored weekly for 3 months and at the end of the study the animals were sacrificed, and the organs were extracted and weighed for anthropometric, oxidative stress and histological evaluations. Results: Exposure to radiation released by the monazite sands did not cause anthropometric alterations or blood pressure change in the animals. Similarly, there was no change in the quantification of ovarian follicles between the radiation groups and the control group. There was no difference in the oxidative stress quantification by the thiobarbituric acid reactive substance and advanced oxidation protein product methods in the ovaries. There were no evidenced damages in the structure of the renal tissue. It was observed the presence of granulomas in the hepatic tissue and alterations in the nuclei of the hepatocytes. Conclusions: Our results suggest that the continuous exposure of females rats to 3.6 and 20 μSv h-1 doses of gamma radiation slightly affected the hepatic tissue, but did not alter the histological parameters in the kidneys and ovaries and oxidative stress.

Título: Tributyltin chloride induces renal dysfuction by inflamation and oxidative stress in female rats Autor(es): COUTINHO, João V.S. http://lattes.cnpq.br/6600915137024415 https://orcid.org/0000-0003-3128-8767; FREITAS-LIMA, Leandro C.; FREITAS, Frederico F.C.T.; FREITAS, Flávia P.S. Abstract: Tributyltin chloride (TBT)is an organometallic pollutant thatis used as a biocide in antifouling paints. TBT induces several toxic and endocrine-disrupting effects. However, studies evaluating the effects of TBT on renal function are rare. This study demonstrates that TBT exposure is responsible for improper renal function as well as the development of abnormal morphophysiology in mammalian kidneys. Female rats were treated with TBT, and their renal morphophysiology was assessed. Morphophysiological abnormalities such as decreased glomerular filtration rate and increased proteinuria levels were observed in TBT rats. In addition, increases in inflammation, collagen deposition and a-smooth muscle actin (a-SMA) protein expression were observed in TBT kidneys. A disrupted cellular redox balance and apoptosis in kidney tissue were also observed in TBT rats. TBT rats demonstrated reduced serum estrogen levels and estrogen receptor-a (ERa) protein expression in renal cortex. Together, these data provide in vivo evidence that TBT is toxic to normal renal function and that these effects may be associated with renal histopathology complications, such as inflammation and fibrosis.
