Juliana Costa Shiraishi, André Bonadias Gadelha, Lídia Mara Aguiar Bezerra, Luiz Guilherme Grossi Porto
Advances in Physical Education (APE) , 2017, DOI: 10.4236/ape.2017.71003
Regular physical activity has been shown to improve overall physical fitness. The long-term adherence to physical activity is a big challenge for health maintenance; so, pleasure activities, as Hatha Yoga (yoga), may represent a good alternative on both individual and public contexts. Yoga is an ancient activity designated to both health and unhealthy individuals. It integrates physical, mental, and spiritual components and may improve aspects of health. The aim of the present study was to evaluate the effects of a 12-week systematized yoga intervention on health-related physical fitness components assessed by body mass, body mass index (BMI), waist circumference (WC), relative body fat, abdominal endurance, upper body endurance, hamstring flexibility, and cardiorespiratory fitness. The study was performed at University of Brasília, Faculty of Physical Education, Distrito Federal, Brazil. Twenty-five young healthy yoga novices (22.36 ± 2.40 years), both gender, volunteered to participate in this study. The intervention was based on 50 minutes yoga class, twice a week for 12 weeks, involving physical poses, meditation, and relaxation. Measurements were performed one week prior to and one week after the yoga intervention. Collecting data included age, gender, height, body mass, body fat estimates and physical fitness tests. Body fat percentage was determinated by the measure of skinfolds at seven sites. Muscle strength/endurance was evaluated by push-up and sit-up tests. Hamstring flexibility was assessed using sit-and-reach test protocol. The 12-minutes Cooper test was performed to estimate cardiorespiratory fitness. Participants that attended at least 75% of the total sessions were included in the study results. The results showed 1.3 (1.0 - 4.0) cm decrease in WC and 0.7 (0.9 - 1.5) decrease in body fat percentage, and 7.8 (2.0 - 5.0) cm increase in hamstring flexibility and 3.0 (1.0 - 4.0) in abdominal endurance, after the yoga intervention (p < 0.01). In conclusion, the present study found that a 12-week yoga program improved physical fitness in young healthy subjects.

Um estudo da implementa o de mudan as sintáticas no português brasileiro: a análise da dados escritos
Juliana Costa Moreira,Elaine Chaves
Caligrama : Revista de Estudos Romanicos , 2012,
Abstract: Resumo: Estudos diacr nicos têm identificado o final do século do XIX como um momento em que mudan as sintáticas foram implementadas no português brasileiro (PB). Alguns desses estudos foram listados por Tarallo (1993) e por meio deles o autor concluiu que o final do século XIX foi o período em que surgiu a gramática do PB. Apresentamos os resultados de outros dois estudos que se enquadram nesse perfil (CHAVES, 2006; MOREIRA, 2008) e utilizam amostras escritas como fonte de dados, no intuito de mostrar que os resultados podem ser interpretados de outro modo. Argumentamos que mudan as descritas a partir de dados escritos n o se implementaram no período apontado, mas anteriormente. Nesse sentido, por extens o, sugerimos que o final do século XIX n o é o período em que emerge a gramática do PB. Esse é o momento em que essa gramática se massifica no domínio da escrita, uma vez que inova es linguísticas tornam-se visíveis na escrita quando s o bem aceitas na fala. Palavras-chave: Implementa o linguística; língua escrita; gramática; português brasileiro; século XIX. Abstract: Diachronic studies have shown that the end of the 19th century is a period in which syntactic changes were implemented in Brazilian Portuguese (BP). Some of these studies were listed by Tarallo (1993), arguing that the end of the 19th century was the period that witnessed the emergence of BP grammar. We present the results of two other studies that share the same profile (CHAVES, 2006; MOREIRA, 2008), in which written samples were analysed, in order to show that the results can be interpreted in a different way. We argue that the changes evidenced by the written samples analysis had been implemented in a previous period. It is our assumption that the end of the 19th century is not the period that witnessed the emergence of BP grammar. This period corresponds to the massification of grammar in written language, since linguistic innovations manifest in written language when they are accepted in oral language by speakers. Keywords: Linguistic implementation; written language; grammar; Brazilian Portuguese; 19th century.
Expression of Cyclooxygenase-2 and Ki-67 in Actinic Keratosis and Cutaneous Squamous Cell Carcinoma in Dogs  [PDF]
Sabrina Dos Santos Costa Poggiani, Mário Roberto Hatayde, Renée Laufer-Amorim, Juliana Werner
Open Journal of Veterinary Medicine (OJVM) , 2012, DOI: 10.4236/ojvm.2012.22007
Abstract: Actinic keratosis is a common disease in humans, which also affects dogs. Lesions occur in chronically sun exposed areas, such as flank, ventral and lateral abdomen. It has been reported that actinic keratosis is a pre-neoplastic disease which may evolve into squamous cell carcinoma (SCC), which is one of the most frequent malignant neoplasm in dogs. The aim of this research was to investigate the relationship between COX-2 and cell proliferation on the outcome of dogs with actinic keratosis and cutaneous squamous cell carcinoma. This study included 10 skin sections of actinic keratosis (G1) and 10 cutaneous SCC (G2). Data including age, breed, gender and histopathological findings were documented. Paraffin-embedded tissues were retrieved for COX-2 and Ki-67 staining. American Pit Bull Terrier dogs were the most affected ones in both G1 and G2, the mean age was 4.3 (±0.8) years and 5.6 (±1.7) years, respectively. Mean score of COX-2 immunostaining in G1 and G2 was 8.16 (±3.51) and 8.56 (±1.03), respectively. Mean percentage of immunopositive cells for Ki-67 in G1 and G2 was 15.77 (±8.81) and 17.71 (±12.21), respectively. There was no association between COX-2 expression and Ki-67, recurrence, survival and metastasis rate (p > 0.05). These findings highlight the role of COX-2 and Ki-67 in carcinogenesis, but do not confirm the relationship between COX-2 expression and increased cell proliferation in dogs. COX-2 may play a role in carcinogenesis, but this pathway is not responsible for cellular proliferation in actinic keratosis and cutaneous SCC in dogs. Both markers were not useful tools to differentiate the outcome of affected dogs.

Abstract: from october 1997 to may 1998, several interviews with producers of hydroponic crops took place in distrito federal with the objective of not only verifying but also identifying the present situation regarding the constraint points in the production system. eighteen producers were identified in a ratio of 50km away from brasília. the main crops are lettuce and tomato, which occupy an area of 2,7 ha and 0,5 ha, respectively. it was also verified that the majority of the structures used was made of wood and steel, which account for an average cost of r$ 26,00/m2 for lettuce production, and of r$ 20,00/m2 for tomato production. the unit cost for lettuce is around r$ 0,25 and the average market price is r$ 0,45, whereas the tomato is sold for r$ 1,20/kg. due to the recent production, tomato producers haven't yet figured out the real costs. the average productivity observed was of 300t/ha/year for lettuce, and of 104t/ha/cycle for tomato. the main buyers are ceasa, supermarkets, restaurants, vegetable stores, and green groceries stores. one producer exports lettuce to manaus (am). half of the producers do not use chemicals. the main problems faced by lettuce producers are the lack of technical assistance, "tipburn", analysis of the nutrient solution, inward structure heating, diseases and pests. on the other hand, tomato producers face cracked fruits, as well as diseases and pests. vegetables hydroponic cropping is seen as an alternative for the feasibility of the agribusiness of the region, besides allowing a substantial reduction of chemicals utilization. approximately 44% of the producers have no technical assistance and are also operating through attempts, which demands a more effective support by universities, research institutes and extension services.

Rossi, Juliana Vendramini;Costa, Marilisa Nano;
Arquivos Brasileiros de Oftalmologia , 2003, DOI: 10.1590/S0004-27492003000300017
Abstract: the authors describe the use of a teflon catheter as an intracanalicular stent in order to increase its accessability to ophthalmologists.the technique is based on the identification of the canalicular borders followed by the introduction of a teflon catheter (22 or 24) into the canalicular lumen. three full-thickness sutures are placed at the canaliculum using a 8-0 mononylon or a 8-0 vicryl. this technique can be used in cases of non-complicated lacerations, in which catheterization is still possible.

Chaves, Juliana Siqueira;Da Costa, Fernando Batista;
Revista Brasileira de Farmacognosia , 2008, DOI: 10.1590/S0102-695X2008000300009
Abstract: in this study, we present a proposal for the physical and chemical quality control of the powder of the species t. parthenium (feverfew) and its hydroalcoholic extract obtained by percolation. the sesquiterpene lactone parthenolide, the main active compound of this plant, was quantified by hplc and its content was found to be 0.49% in the powder and 1.06% in the extract. the total content of flavonoids, determined by uv spectroscopy, was found to be 0.54% in the powder and 1.05% in the hydroalcoholic extract. santin, the main flavonoid of this species, was isolated and further identified in the extract by hplc. since parthenolide can also be found in other asteraceae species, the analysis of santin is important to certify the authenticity of the plant material. the results confirmed the authenticity of the plant material and the efficiency of the extraction procedure.
Estudo de variabilidade do vento em escala sazonal sobre o nordeste brasileiro utilizando o RAMS: os casos de 1973-1974 e 1982-1983
Oliveira, Juliana Lima;Costa, Alexandre Araújo;
Revista Brasileira de Meteorologia , 2011, DOI: 10.1590/S0102-77862011000100006
Abstract: the purpose of this work is to analyze the influence of climate variability and general circulation impact on the behavior of the winds over northeast brazil, with emphasis in the atmospheric model as a feasible tool for forecasting of wind power generation. statistical analysis suggest that there is a significant correlation between the climate indices (el ni?o and dipole indices) and the average wind speed over northeast brazil, mainly between february and may, period that corresponds to the four-month rainy season. data from ncep reanalysis for extreme events (as the 1982-1983 el ni?o events and the 1973-1974 la ni?a events) suggest that, in those cases, the influence of the general circulation is so pronounced that strong events of el ni?o and la ni?a act as to intensify and to weaken, respectively, the winds over that region. as the smaller scale circulation associated to the sea breeze system and topographic forcing are relevant to determine the characteristics of the local wind, a mesoscale atmospheric model, the regional atmospheric modeling system, (rams) was used to simulate the wind speed and direction from july to june of 1973-74 and of 1982-83, in order to estimate the wind variability on a seasonal time scale and the possible impacts of wind variations on the wind energy generation over northeast brazil
