Introduction : The aging is characterized by a reduction in the effectiveness of skills, among them the loss of the flexibility. The hamstring muscles may be affected by the decreased flexibility occurs when elderly can present limitation of gait, low back problems and osteomuscular. Among the techniques used to evaluate the flexibility of the hamstring muscles are the Sit and Reach Test and Computerized Photogrammetry evaluation of the popliteal angle . However, the scientific literature doesn’t provide consistent data on the correlation of these forms of evaluation. Objective: To analyze the correlation between the sit and reach test and Computerized Photogrammetry evaluation of the popliteal angle used to assess the flexibility of the hamstring muscles in elderly women. Method: This was a cross-sectional, observational study, consisting of 39 elderly, healthy. The evaluation was composed by forms with personal details and physical examination (body weight, height and body mass index), and the evaluation of tests to measure the flexibility of the hamstring muscles (Sit and reach test and Computerized Photogrammetry evaluation of the popliteal angle). The correlation of the data was done by using the Spearmam’s rank correlation coefficient, with a significance level of 5% (p<0.05). Results: The data showed a positive correlation between Sit and Reach Test Computerized Photogrammetry and the popliteal angle of the right leg (r=0.4690, p=0.0026) and the left leg (r=0.3604, p=0.0241). Conclusion: The data from this study allow conclude that the tests for assessing hamstring flexibility in elderly women, the Sit and Reach Test and Computerized Photogrammetry evaluation of the popliteal angle are complementary because it doesn’t correlate strongly.

Indivíduos com Paralisia Cerebral apresentam desenvolvimento motor atípico, caracterizado por alterações posturais, de coordenação motora e de tônus muscular, que resulta em limitações no desempenho de atividades funcionais. Neste contexto destaca-se a prescrição e confecção de recursos de tecnologia assistiva com objetivo de maximizar as habilidades funcionais destas pessoas e prover sua inclusão social. Os indivíduos com paralisia cerebral, muitas vezes, têm dificuldade para a manutenção da dinâmica corporal, principalmente na postura sentada. O objetivo deste estudo foi o de confeccionar uma cadeira e mesa escolar adaptadas com material de baixo custo e verificar sua eficácia no desempenho grafomotor de uma criança com paralisia cerebral. O participante foi uma criança com diagnóstico de paralisia cerebral diplégica, do gênero masculino. A coleta e registro dos dados foram feitos em três momentos, com a criança posicionada no mobiliário adaptado, no mobiliário escolar comum e novamente no mobiliário adaptado, para se estabelecer a comparação. A análise de dados se deu por meio de testes estatísticos não paramétricos. Não houve significância estatística e foi verificada uma inconstância nos dados apresentados, já que não se pode afirmar ao certo qual mobiliário foi mais eficaz na realização da atividade proposta e nem se houve aprendizado motor com a sua repetição. Esse fato não invalida a adequação de mobiliário escolar ao aluno com paralisia cerebral, visto que este é um fator importante para favorecer o controle e estabilidade postural ao individuo, o que interfere na coordenação motora fina destes indivíduos, influenciando no seu desempenho em atividades escolares.

O sucesso das restaurações metálicas indiretas depende, dentre outros fatores, de uma união eficaz entre a estrutura metálica e o cimento dentário empregados. Sabe-se que os primers para metal atuam com comprovada eficácia na resistência adesiva dos cimentos resinosos às ligas nobres. Entretanto, pouco foi estudado sobre o efeito de tais materiais em ligas não nobres. O propósito deste estudo foi avaliar a eficácia de primers para metal na resistência ao cisalhamento da união entre cimentos resinosos e metais não nobres. Discos (9 mm de diâmetro e 3 mm de altura) foram fundidos em liga de NiCr (n=80) e em titânio comercialmente puro (Ti c.p.) (n=80) e foram incluídos em anel de PVC com resina acrílica quimicamente ativada. As superfícies dos discos foram regularizadas com lixas de carbeto de silício de granulação 320, 400 e 600 e jateadas com partículas de óxido de alumínio de 50 µm. Espécimes de cada metal foram divididos em quatro grupos (n=20). Uma matriz metálica bi-partida (5 mm de diâmetro interno e 2 mm de altura) foi posicionada na superfície do espécime. As áreas adesivas receberam um dos seguintes tratamentos: 1) Panavia F; 2) Alloy Primer e Panavia F; 3) Bistite DC e 4) Metaltite e Bistite DC. Para evitar a exposição dos cimentos à luz, estes foram espatulados e inseridos na matriz dentro de uma câmara de revelação radiográfica. Quarenta minutos após a confecção, os espécimes foram armazenados em água destilada a 37ºC por 24 horas e então termociclados (1.000 ciclos, 5ºC e 55ºC, 30 segundos cada banho). Após a termociclagem, os espécimes foram armazenados novamente nas mesmas condições descritas anteriormente por um período de 24 horas (n=10) ou de 6 meses (n=10) antes do ensaio de cisalhamento em uma máquina de ensaios mecânicos (Material Test System 810).

The use of rainwater for non-potable purposes generates a reduction in the consumption of treated water, however, this reduction is not observed in the generation of wastewater, as this is independent of the water source. In Brazil, the pricing on the services of collection and treatment of sewage, in general, is based on the coefficient of return of the sewage disposal system, which has a relation sewer / water proportional to the consumption of treated water measured at the consumer unit. The use of rainwater originating from utilization systems infer on the coefficient, underestimating the volume of wastewater generated. Therefore, this study presents a methodology for setting the coefficient of return. Different roof areas, reservoir volumes and rates of water consumption situations were simulated. The behavior of adjustment of the coefficient of return were also analyzed for the average area per capita roof (m² / inhabitant) of Rio Claro - SP. As a result, it can be seen that the adjustment of the coefficient of return is directly proportional to the increase of the roof areas and the volumes of reservoirs, and inversely proportional to the total water demand. The corrected coefficient of return showed the minimum value of 0.83 and a maximum value of 1.45, this variation corresponds to the maximum ratio between the demands of total water and rainwater, since the exploitation of rain water should be used only for non-potable uses, according to NBR 15527 / 07. To the municipality of Rio Claro - SP was noted an adjustment of the coefficient of return ranging from 0.99 to 6.61

Cutaneous melanoma is a malignancy caused by the uncontrolled proliferation of melanocytes. Has been increasing in incidence and mortality over the years. This type of tumor may arise in the skin or any other place where there was migration of neural crest cells. Melanocytes are located in the basal layer of the epidermis forming the epidermal melanin unit, involving a melanocyte to 36 keratinocytes. The proliferation of melanocytes depends on this relationship with the keratinocytes, gap junctions, E-cadherin and desmoglein. The basal membrane is responsible for promoting the integrity of the skin, their adhesion structures shown to be altered in several skin diseases. Some molecules that play the role of adherence in this membrane are the laminins, type IV collagen and type XVII and perlecan. Analysis of protein expression of cell adhesion molecules in melanoma by immunohistochemistry on tissue microarray (TMA). We selected paraffin blocks of patients who were diagnosed with cutaneous melanoma in the period 1995 to 2010, reaching a sample of 124 cases. All these have gone through review of preparation for subsequent histological analysis of tissue microarray (TMA). The protein expression will be analyzed by immunohistochemistry, using markers anti-laminin, anti-collagen type IV and type XVII and anti-perlecan. There was a predominance of female patients, Caucasians and southeastern Brazil. There were frequent in type of extensive superficial ulcers with Breslow depth greater than 4 mm, Clark level IV and mitotic index greater than 6 mitoses per cga. The patients, most of them were female with mean age of 57.13 years and Caucasian. The most frequent histological type was extensive superficial followed by acral lentiginous. Predominated cases very deep, with Breslow thickness greater than 4 mm, Clark IV, ulcerated and on average by 9 cga mitosis, leading to worse prognosis in this sample.

The behavior and experience of pain are characterized by alertness and anxiety, which disappear soon after the healing process begins. Based on this area, the present study aimed to quantify the expression of c-fos in segments of the brain of rats after surgical stimulation in one rear hind paw (analgesia), using anesthesia with sodium thiopental and practices of acupuncture pre and post operative. The animals were stimulated with intraperitoneal injections of solution (NaCl) 0.2% (2ml), and divided into three groups, control, preoperative and postoperative. Each treatment was divided in manual acupuncture (AM) and electroacupuncture (EA). The animals were randomly distributed in each group. The c-fos expression was quantitated using immunohistochemistry for all situations. The results showed a great efficiency of all treatment compared to the control group (p <0.001), thus reenforcing data in the literature on the potential of acupuncture analgesia. There were no statistical differences among the different treatments, although there was a trend of EA being more efficient than AM

Hypothermia is a common phenomenon in the perioperative period, and it affects 60 to 90% of patients submitted to anesthetic-surgical procedures. In order to minimize its incidence, warming methods are used. Such methods can be passive, such as orthopedic cotton, sheets and blankets, or active, such as warm-air blankets and thermal mattresses. In this scenario, the present study aimed at comparing two warming methods used in the intraoperative period. Patients submitted to abdominal surgery in the specialties of gynecology and gastric surgery from August to September 2010 were included in the study. After randomization, they were divided into two groups: one using a thermal blanket (group I) and one using orthopedic cotton (group II). At last, 9 patients were included. The variables for each question were considered according to occurrence frequency. Comparison between groups was performed by Student’s t test. With the purpose to analyze whether there was an association, the chi-square test or Fisher’s Exact test was used. Whenever it was applicable for multiple comparisons, Tukey’s test was utilized; p values < 0.05 were considered to be statistically significant for analysis. The sample comprised 6 males and 3 females submitted to gynecological and gastric surgeries. Their mean age was 48 years for group I and 46.2 years for group II. A predominance of general anesthesia was observed. The time of permanence in the operating room ranged from 80 to 360 minutes. With regard to warming parenteral solutions, the procedure was performed on 5 patients, and infusion of warm solution into the abdominal cavity was performed on 50% of the sample. Concerning the warming method used, 5 patients used a thermal blanket. In view of the results presented, it was not possible to conclude which warming method should be used due to sample size

O capítulo 1 trará as mais importantes correntes teóricas sobre inflação, desde meados do século XX até o fim deste século. Também será demonstrado o pensamento da corrente Cepalina, mais especificamente os autores brasileiros que escrevem acerca da inflação que era observada no período (década de 1980). Assim, chegaremos a como se é formulado o regime de metas de inflação. Após isso, foi efetuada uma cronologia desde a implementação do plano real no Brasil até a inserção do regime de metas de inflação em 1999. O capítulo 2 tem como seu conteúdo principal abordar a eficácia do regime de metas de inflação. Para isso, trará um modelo estatístico, mostrando e interpretando os resultados obtidos. Após isso, o capítulo trará um panorama geral de como evoluiu o regime de metas de inflação no Brasil nos anos em que o trabalho se situa. Na conclusão, serão trazidos os principais questionamentos do trabalho, bem como as respostas encontradas para este e os eventuais desafios que um aprofundamento maior poderá acarretar
