The Use of Angiotensin-I Converting Enzyme I/D Genetic Polymorphism as a Biomarker of Athletic Performance in Humans
Maria Fernanda De Mello Costa,Ron Slocombe
Biosensors , 2012, DOI: 10.3390/bios2040396
Abstract: Angiotensin II is a key regulator of blood pressure and cardiovascular function in mammals. The conversion of angiotensin into its active form is carried out by Angiotensin I-Converting Enzyme (ACE). The measurement of ACE concentration in plasma or serum, its enzymatic activity, and the correlation between an insertion/deletion (I/D) genetic polymorphism of the ACE gene have been investigated as possible indicators of superior athletic performance in humans. In this context, other indicators of superior adaptation to exercise resulting in better athletic performance (such as ventricular hypertrophy, VO 2 max, and competition results) were mostly used to study the association between ACE I/D polymorphism and improved performance. Despite the fact that the existing literature presents little consensus, there is sufficient scientific evidence to warrant further investigation on the usage of ACE activity and the I/D ACE gene polymorphism as biomarkers of superior athletic performance in humans of specific ethnicities or in athletes involved in certain sports. In this sense, a biomarker would be a substance or genetic component that could be measured to provide a degree of certainty, or an indication, of the presence of a certain trait or characteristic that would be beneficial to the athlete’s performance. Difficulties in interpreting and comparing the results of scientific research on the topic arise from dissimilar protocols and variation in study design. This review aims to investigate the current literature on the use of ACE I/D polymorphism as a biomarker of performance in humans through the comparison of scientific publications.
Quietas e caladas: as atividades de movimento com as crian?as na Educa??o Infantil
Iza, Dijnane Fernanda Vedovatto;Mello, Maria Aparecida;
Educa??o em Revista , 2009, DOI: 10.1590/S0102-46982009000200013
Abstract: this article discusses the movement activities in everyday routines of the basic education teachers, under the perspective of vigotski′s' historical-cultural theory, whose conception about childish development has a focus on the culture and teachers' mediated activities, as a determination for the childish learning and development. the movement activities transcend the motor development. it is related to problems resolution, questions, creativity, memory, attention, abstraction, and so on. the basic education teachers investigated have experience on working with children, but they don't have knowledge about how to work with movement activities in the educational perspective and thus, they keep the children in a situation of non-movement. those practices about how to maintain the children quiet and silent show the teachers' conceptions about child and movement, indicating the urgency of a reformulation on the initial and continual processes and courses of the basic education teachers.

Semina : Ciências Biológicas e da Saúde , 2007,
Abstract: This descriptive and exploratory study was carried out in order to verify the incidence of and characterize accidents with spiders, from 1995 to 2002, in the city of Chapecó, State of Santa Catarina. Notification records kept by the Center for Epidemiologic Surveillance of Chapecó concerning that period of time were analyzed, and the number of occurrences was calculated. In Chapecó, 131 accidents with spiders occurred during that period of time, and the incidence of araneism was of 0.8% in 1995; 0.0% in 1996; 2,2% in 1997; 8.66% in 1998; 11.9% in 1999; 18,4% in 2000; 17,5% in 2001 and 29,8% in 2002. Sixty-two point six per cent (62,6%) of these accidents were caused by spider of the genera Loxosceles. Most of them occurred with women and adults from 21 to 60 years old (54,9%). Approximately 80% of the accidents occurred in the urban area, since 80% of the victims lived in the city. The parts of the body that were most bitten by spiders were thigh/legs, foot/toes and hand/fingers. The main clinical alterations presented by the patients were pain, edema and erythema. The season when most accidents occurred was the Spring, and more than 40% of the victims were doing housework . Results from this study showed that the number of accidents has increased significantly in recent years, and that the implementation of public health policies in this area to prevent such accidents to happen is necessary. Este estudo, de caráter descritivo e exploratório, foi realizado com o objetivo de verificar a incidência e caracterizar dos acidentes com aranhas de 1995 a 2002 no município de Chapecó, Santa Catarina, bem como caracterizar esses acidentes. Para tanto, verificaram-se os registros das notifica es realizadas pela Vigilancia Epidemiológica de Chapecó entre os anos e calculou-se a freqüência das mesmas. Em Chapecó, ocorreram 131 acidentes com aranhas durante o período estudado, e a incidência de araneísmo foi de 0,8% em 1995; 0,0% em 1996; 2,2% em 1997; 8,7% em 1998; 11,9% em 1999; 18,4% em 2000; 17,5% em 2001 e de 29,8% em 2002. Dentre eles, 62,6% foram ocasionados por aranhas do gênero Loxosceles. A maioria ocorreu com mulheres e adultos entre 21 e 60 anos (54,9%). Cerca de 80% dos acidentes ocorreram na área urbana, visto que quase 80% das vítimas residiam nesta área. As partes do corpo mais picadas pelas aranhas foram coxas/pernas, pé/artelhos e m o/dedos. As principais altera es clínicas apresentadas pelos pacientes foram dor, edema e eritema. A esta o de maior ocorrência de acidentes foi a primavera, e as vítimas em mais de 40% encontravam-se em atividades no
Development of Physical and Optical Methods for In-shell Brazil Nuts Sorting and Aflatoxin Reduction
Fernanda Robert de Mello,Vildes Maria Scussel
Journal of Agricultural Science , 2009, DOI: 10.5539/jas.v1n2p3
Abstract: Physical methods for mechanically in-shell Brazil nut sorting by color, size, density and inner deterioration were developed to assess nut quality and reduce aflatoxin contamination. Nuts were able to be sorted by color utilizing the standard shell chromaticity components L*, a* and b* at ranges of 31.51 to 48.64, 4.09 to 10.07 and 11.90 to 22.95, respectively. It produced a homogeneous color batch and segregated the off-standard ones (darkest, lightest and stained). By size sorting utilizing three oval sectioned trays with the following dimensions 40x25, 35x23 and 20x19.5 mm [length x width] and vibration, nuts were sorted into three sizes Groups: I, II and III for large, medium and small, respectively. Through density sorting the light nuts (shell/nut <1.5) which have inner mass reduction by fungi growth and/or dehydration, were separated with two compressed air streams from the healthy ones. Utilizing near infrared (NIR) spectrophotometry, the nuts inner deterioration was detected, with no need of de-shelling them at the wavelength range of 2200 to 2500 nm. Any nut measurement detected, lower or higher than those sorting settings, was considered off-standard and rejected. Pools of the final standard and off-standard nuts were analyzed for aflatoxins by LC-MS/MS. No toxin was detected in the final standard batch up to the method LOQ (0.08, 0.09, 0.10 and 0.12 ?g/kg for AFB1,AFB2, AFG1, AFG2, respectively). On the other hand, the off-standard rejected batch had 16.4 ?g/kg of AFB1. These methods are important tools for building an in-shell Brazil nut sorting machine to assess nut quality and reduce aflatoxin contamination.

Atmospheric and Climate Sciences (ACS) , 2016, DOI: 10.4236/acs.2016.62029
Abstract: Important international reports and a significant number of scientific publications have reported on the abrupt decline of Arctic sea ice and its impact on the Global Climate System. In this paper, we evaluated the ability of the newly implemented Brazilian Earth System Model (BESM-OA) to represent Arctic sea ice and sensitivity to CO2 forcing, using decadal simulations (1980-2012) and future scenarios (2006-2100). We validated our results with satellite observations and compared them to Coupled Model Intercomparison Project, Phase 5 (CMIP5) for the same numerical experiment. BESM results for the seasonal cycle are consistent with CMIP5 models and observations. However, almost all models tend to overestimate sea ice extent in March compared to observations. The correct evaluation of minimum record of sea ice, in terms of time, spatial and area remains a limitation in Coupled Global Climate Models. Looking to spatial patterns, we found a systematic model error in September sea ice cover between the Beaufort Sea and East Siberia for most models. Future scenarios show a decrease in sea ice extent in response to an increase in radiative forcing for all models. From the year 2045 onwards, all models show a dramatic shrinking in sea ice and ice free conditions at the end of the melting season. The projected future sea ice loss is explained by the combined effects of the amplified warming in northern hemisphere high latitudes and feedbacks processes.

Abstract: teaching science to deaf-mute children has several limitations. in recent years, some techniques and resources have been presented to this public. however, many approaches still have to be done. the contact of these students with science is made preferably by learning through the language of signals. the main objective of the present work is to encourage the use of the "tale and box" methodology as an efficient way to apply scientific knowledge for deaf-mute children. the tale was about ema (deaf-mute children) and her friends learning the importance of paleontology and fossils through the visit of a paleontologist to their school. the story was written in portuguese language, which was translated and adapted to the brazilian sign language - libras. the story has been implemented in some classes of a deaf-mute care entity in aracaju (sergipe state, northeast brazil). such approach proved to be a valuable methodological tool on transmission of scientific information to deafmute children.
