Quanto a esse ponto, atualmente discutisse a utiliza??o de zonas ?ridas para produ??o de biocombust?veis derivados de esp?cies oleaginosas resistentes ?s condi??es de aridez. A Jatropha curcas L. tem sido indicada como uma esp?cie potencial para esse tipo de utiliza??o, apontada pela literatura como resistente em condi??es desfavor?veis: seca e salinidade. Todavia, pouco ? descrito sobre sua resist?ncia a altas temperaturas e secas severas, principalmente sobre a sinergia de estresses combinados, cen?rio t?pico de regi?es semi?ridas. Este trabalho visa portanto avaliar os efeitos da temperatura sobre a J. curcas em condi??es de seca. O estresse h?drico foi aplicado utilizando duas concentra??es de PEG6000 dilu?das em solu??o hidrop?nica, induzindo potencial h?drico de -0,3 e -0,7 MPa. J? o estresse t?rmico foi conduzido em B.O.D. ? 40?C. Ap?s aplica??o dos estresses, o material vegetal foi coletado para avalia??o dos indicadores de estresse como conte?do relativo de ?gua (CRA) e dano de membrana (DM), al?m das determina??es bioqu?micas de prote?nas, amino?cidos totais (AALT), prolina (PRO) e glicina beta?na (GB), a??cares sol?veis totais (AST) e amido. Os resultados mostraram que o CRA pouco se altera, em condi??es de estresse e DM foi menor sob estresse t?rmico. Os solutos AALT, PRO e amido tiveram concentra??es mais significativas em folhas, enquanto que prote?nas, GB e AST foram mais significativas nas ra?zes. Quanto ? observa??o dos efeitos provocados pelo estresse h?drico, este trabalho fez compara??es a resultados semelhantes obtidos em outros estudos, refor?ando afirma??es sobre a efici?ncia das respostas da J. curcas em condi??es de seca. Todavia as plantas se mostraram mais suscept?veis ao estresse t?rmico, embora, quando em estresses combinados as respostas tenderam ao aumento em compara??o ao estresse t?rmico isolado. No geral, estes resultados abrem espa?o para que novos estudos sejam realizados a fim de testar os efeitos dos estresses combinados sobre a J. curcas e quais respostas a planta pode apresentara sob estas condi??es. / Biofuels are a focus of discussion when it comes to renewable energy. On this point, actually disc uss the use of arid zones for production of biofuels derived from oil plant species resistant to arid conditions. Jatropha curcas L. has been indicated as a potential species for this application, because it resistance to unfavorable conditions as: drought and salinity. However, a few studies have been described about its resistance to high temperatures and severe droughts, especially on the synergy of combined stresses, typical of semiarid lands. This study aims to evaluate the temperature effects of J. curcas on dry conditions. Water stress was caused using two concentrations of PEG6000 diluted in hydroponic solution, inducing water potentials of - 0.3 and - 0.7 MPa, while the heat stress was conducted in growth chamber at 40?C. After applying the stress, the plant material was collected for evaluation of stress indicators such as relative water content (RWC), membrane damage (MD) and absolute growth rate (AGR), and the biochemical determinations of proteins, total amino acids (TFAA), proline (PRO), glycine betaine (GB), total soluble sugars (TSA) and starch. The results showed that the RWC few changes in stress conditions and MD was lower under heat stress, probably due to the contribution of solutes such as protein and GB. Solutes TFAA, PRO and starch had more significant concentrations in leaves, while proteins, GB and TSA were more significant in the roots. TFAA and PRO were solutes with more significant responses on leaves, mainly in severe drought under heat stress. GB had an increase in the concentrations both in leaves and in roots, when under to drought and heat stress. Starch concentrations was reduced, which may be a reflex the reduction of AGR of the seedlings. The data suggest that J. curcas is able to withstand the effects of droughts tress, considering fewer changes of the CRA under the studied conditions. Overall the seedlings were more sensitive to heat stress. However, when combined the both drought and heat stresses, the results showed an increasing trend in relation to just heats tress.

Piata in soils contaminated by picloram, determining its influence on physiological and vegetative characteristics in beans, used as bioindicator. For this, two experiments were conducted, the first consisting of the application of different doses of the herbicide picloram ( 0 , 7.5, 15 , 30, 60 and 120 g ha - 1 ) which were cultivated Brachiaria Brizantha cv. Piata for a period of 150 days. The second experiment consisted of permanence B. brizantha cv. Piat? on the soil in different periods (150 , 210, 240, 270 to 300 days) after the application of a dose of 240 g ha-1 of picloram. The experimental design for both experiments was a randomized block with five replications. The evaluations were made by measuring the height ( cm ) , dry matter ( g ) and mass of green matter ( g ) of Brachiaria plants in the trial 1 , and dry matter ( g ) of Brachiaria plants for respective periods proposed in the trial 2. For the bean plants, were made evaluations at 50 days after sowing (DAS) of the following variables: plant height ( cm ) , dry matter ( g ) , mass of green matter ( g ) , phytotoxicity ( % ) to 25 and 50 days , leaf area ( cm2 ) , number of leaves per plant , maximum photosynthetic efficiency ( Fv / Fm ) and the relative rate of electron transport (ETR). Evaluating the effects on plants, the phytoremediation, and the bioindicator. It can be concluded that the remediation provided by the cultivation of B. brizantha cv. Piata was effective only when were applied doses below 60 g ha - 1 in the soil. After the application of picloram, the longest period on the soil with brachiaria (300 DAS) provided the greatest potential to remediation and hence improving the physiological and morphological characteristics of the bean.

Entre as esp?cies desse g?nero, a Euphorbia tirucalli ? uma planta de uso difundido no Brasil e em algumas regi?es, tal como a do Vale do Jequitinhonha. H? ind?cios de que o l?tex de E. tirucalli tenha atividade antitumoral e antiviral, por?m, pouco se sabe sobre os mecanismos envolvidos nessa a??o. ? prov?vel que o mecanismo de a??o para tais atividades envolva a ativa??o de leuc?citos e a produ??o de citocinas para o direcionamento de uma resposta antiviral e antitumoral efetivas. Diante disso, o presente trabalho avaliou a produ??o de citocinas TNF-?, IFN-?, IL-4 e IL-10 nas popula??es e subpopula??es leuc?cit?rias do sangue perif?rico estimulados com o l?tex bruto da referida planta. Para tal, leuc?citos do sangue perif?rico de vinte indiv?duos h?gidos foram incubados por 4 horas com o l?tex bruto de E. tirucalli dilu?do em Dimetilsulfoxido (DMSO) e constituiu o grupo l?tex (Lt). Culturas celulares incubadas com salina e DMSO, utilizando-se o mesmo per?odo de incuba??o, constitu?ram as culturas controle n?o estimuladas (CC) e controle de solvente (DMSO), respectivamente. Ap?s o per?odo de incuba??o, as c?lulas foram marcadas com anticorpos monoclonais espec?ficos para receptores de superf?cie celular CD4, CD8 e CD14, bem como para as citocinas intracitoplasm?ticas TNF-?, IFN-?, IL-4 e IL-10. A aquisi??o e an?lise dos dados foram realizadas por citometria de fluxo. Os resultados demonstraram um aumento significativo (p < 0,05) no percentual de linf?citos T e sua subpopula??o T CD4 positivos para as citocinas do tipo 1, TNF-? e IFN-?. Essas citocinas s?o respons?veis por ativar o sistema imune para respostas imunoprotetoras frente ?s infec??es virais e processos tumorais. J? os neutr?filos e linf?citos T CD8, nas culturas estimuladas com o l?tex da planta, apresentaram um perfil misto de produ??o de citocinas do tipo 1 e 2. Esses resultados evidenciaram uma resposta do tipo 1 predominante, in vitro, e uma prov?vel ativa??o de mecanismos moduladores, mediados por linf?citos T CD8 e neutr?filos. Este estudo sugere que a utiliza??o popular da planta em infec??es virais e processos tumorais pode ter algum fundamento, tendo em vista a produ??o preferencial de citocinas do tipo 1 em c?lulas estrat?gicas da resposta imune celular, fundamental no combate ?s patologias mencionadas. No entanto, os estudos in vitro aqui realizados n?o s?o suficientes para garantir que a utiliza??o da planta no contexto in vivo possa, de fato, apresentar tais propriedades. Assim, estudos adicionais, incluindo outros ensaios in vitro, bem como ensaios pr?-cl?nicos, s?o fundamentais para o avan?o das pesquisas envolvendo a utiliza??o de E. tirucalli para fins terap?uticos. / ABSTRACT The use of plants in the family Euphorbiaceae, especially of the genus Euphorbia, has been popularly circulated for the treatment of a variety of infectious, tumoral and inflammatory illnesses. Among the species of this genus, Euphorbia tirucalli is a the plant with widespread use in Brasil and in some regions, such as the Vale do Jequitinhonha. There is evidence that the latex of E. tirucalli has antiviral and antitumor activity, but little is known about the mechanisms involved in this action. It is likely that the mechanism of action for such activities involves leukocyte activation and cytokine production for directing an effective antitumor and antiviral response. Thus, the present study evaluated the production of cytokines TNF-?, IFN-?, IL-4 and IL-10 in the populations and subpopulations in peripheral blood leukocytes stimulated with crude latex of this plant. For such, peripheral blood leukocytes of twenty healthy subjects were incubated for 4 hours with crude latex of E. tirucalli diluted in dimethyl sulfoxide (DMSO) and was the latex group (Lt). Cell cultures incubated with saline and DMSO, using the same incubation period, represent the control cultures that were not stimulated (CC) and solvent control (DMSO), respectively. After the incubation period, cells were stained with monoclonal antibodies specific to cell surface receptors CD4, CD8 and CD14, as well as for TNF-? intracytoplasmic cytokines, IFN-?, IL-4 and IL-10. The acquisition and analysis were performed by flow cytometry. The results showed a significant increase (p <0.05) in the percentage of T lymphocytes and their subpopulation T CD4 positive for type 1 cytokines, TNF-? and IFN-?. These cytokines are responsible for activating the immune system to immunoprotective responses against viral infections and tumor processes. However the neutrophils and T CD8 lymphocytes, in cultures stimulated with the latex of the plant, showed a mixed profile of cytokine production of type 1 and 2.These results showed a response of the type 1 predominant, in vitro, and a probable activation of modulatory mechanisms mediated by T CD8 lymphocytes and neutrophils.This study suggests that the popular use of plant in viral infections and tumor processes may have some foundation, in order to preferential production of type 1cytokines in strategic cells of the cellular immune response, that is essential in combating the diseases mentioned. However, in vitro studies conducted here are not sufficient to ensure that the use of the plant in vivo context may, in fact, possesses such properties. / Disserta??o (Mestrado) ?

Were used oils Avocado (AB), Safflower (CA), Coconut (CO), Flaxseed (LI) and Pequi (PE), and Lard (BAN), Margarine (MAR), Butter (MAN) and Hydrogenated Vegetable Fat (GVH). The AB, CO, CA and LI had higher amounts of total phenolics than the BAN GVH fats, MAN and MAR. The CO had higher amounts of flavonoids than the LI oils, CA, AB and PE. The GVH had higher amounts of flavonoids then the SEA, MAN and BAN. Infrared spectra showed the presence of the hydroxyl group in position 3650-3100nm stretch, which characterizes the EA action in oils and fats. The chromatograms identified the major volatile substances of fatty acids such as caprylic, lauric, myristic, palmitic, stearic, oleic, linoleic, elaidic and Eicosapentaenoic. In the biological test animals received diet plus 10% of each oil and fat, and the control group received only the diet. In supplementation of animals the intake of food coefficient of AB groups, BAN, CA, LI, MAN and PE were the greatest. The BAN groups, MAN, SEA and GVH had higher BMI than group C, which in turn showed a lower rate than the groups AB, CA, CO, LI and PE. For LEE index AB groups, CA, CO, LI and PE had higher rate than GVH, MAN, MAR, BAN and C. The MAN group had higher glucose content. As the fraction of triacylglycerol and HDL-c the BAN group, GVH and MAN was higher than the other. However it can be concluded that even the oils and fats presenting antioxidade activity and presence of phenolics and flavonoids with beneficial health effects, excessive consumption of these causes increased lipid metabolism.

There are many strategies to improve balance, such as resistance physical exercise program, Tai Chi, and more recently whole body vibration. Objectives: to evaluate the efficacy of the whole body vibration over the balance and in life quality in healthy elderly women in the Geriatric clinic of S?o Lucas Hospital. Methods: sixteen weeks randomized clinical trial with 18 elderly women (9 in the interventional group and 9 in the control group) with age greater or equal 60 years, patients in Geriatric clinic of S?o Lucas Hospital. They do not have any severe or disabling diseases whose source is rheumatologic, orthopedic, neurovascular, renal or hepatic. The interventional group has trained in a whole body vibration with frequency between 10-15 Hz and the control has a sedentary life style. Exposure to whole body vibration was intermittent (3 minutes, 1 minute rest) for 11 minutes, three times per week during sixteen weeks. The instruments used were the social and health questionnaire, Berg Balance Scale, World Health Organization Quality of Life (WHOQOL) in the abbreviated version and Lawton?s Instrumental Activities of Daily Living Scale. Subjects were evaluated in the beginning, eight weeks and sixteen weeks after. For the analysis, frequencies, means, standard deviations, chisquare test, Student paired samples t-test, correlation coefficient of Pearson and McNemar test have been applied. The dataset was developed in Excel? 2007 and the data and statistical analysis was performed using SPSS 17. Results: in this study, no statistically significant difference between the interventional and control groups in the balance and life quality (p=0.81) has been achieved. However, a moderate correlation between the balance and the performance in the physical dominium in WHOQOL in the three evaluation moments (rt0=0.47, rt1=0.55 e rt2=0.56) has been shown. Conclusions: in this study, no improvement has been seen in the life quality and balance in the sample evaluated. However, it is important to mention that this limitation can be associated with the sampling size. / Introdu??o: Com o envelhecimento, altera??es do equil?brio s?o inerentes ao processo fisiol?gico, podendo acarretar quedas e complica??es ligadas ao evento.

Objetivos: Investigar o efeito do TMI sobre a adapta??o neural e estrutural do m?sculo diafragma, em jovens sedent?rios, comparar os efeitos do TMI de intensidade leve com os do TMI de intensidade moderada sobre a espessura, mobilidade e atividade el?trica do diafragma e na for?a dos m?sculos inspirat?rios e estabelecer um protocolo para a realiza??o de uma revis?o sistem?tica com a finalidade de avaliar os efeitos do treinamento muscular respirat?rio em crian?as e adultos com doen?as neuromusculares. Materiais e M?todos: Ensaio cl?nico controlado, randomizado e duplo-cego, com uma amostra de 28 adultos jovens, saud?veis e sedent?rios, divididos em dois grupos: treinamento com carga leve (G10%) e treinamento com carga moderada (G55%). Os volunt?rios realizaram, durante 9 semanas, um protocolo de TMI domiciliar, com o POWERbreathe?. O G55% treinou com carga de 55% press?o inspirat?ria m?xima (PIm?x) e o G10% utilizou uma carga de 10% da PIm?x. O treinamento foi realizado em sess?es de 30 repeti??es, duas vezes/dia, seis dias/semana. A cada duas semanas foi avaliada a PIm?x e reajustada a carga. A amostra foi submetida, antes e ap?s o TMI, ? avalia??o atrav?s de ultrassonografia, eletromiografia de superf?cie, espirometria e manovacuometria. Os dados foram analisados pelo SPSS 20.0, foram realizados o Teste t-Student para amostras pareadas para comparar espessura diafragm?tica, PIm?x e PEm?x antes e ap?s o protocolo de TMI e Wilcoxon para comparar os valores de RMS e frequ?ncia mediana (Fmed) tamb?m antes e ap?s protocolo de treinamento. Em seguida, foram realizados o Teste t-Student para amostras independentes para comparar mobilidade e espessura diafragm?tica, PIm?x e PEm?x entre os dois grupos e o teste de Mann-Whitney para comparar os valores de RMS e Fmed tamb?m entre os dois grupos. Paralelamente ao estudo experimental, foi desenvolvido um protocolo com apoio da Colabora??o Cochrane sobre TMI em pessoas com doen?as neuromusculares. Resultados: Houve, nos dois grupos, aumento da for?a muscular inspirat?ria (P<0,05) e expirat?ria no G10% (P=0,009), aumento no RMS e espessura do m?sculo relaxado no G55% (P=0,005; P=0,026) e n?o houve altera??o na FMed (P>0,05). A compara??o entre os dois grupos demonstrou diferen?a no valor RMS (P=0,04) e n?o apresentou diferen?a na espessura e mobilidade do diafragma e for?a dos m?sculos respirat?rios. Conclus?es: Foi identificado aumento da atividade neural e da estrutura diagram?tica, com consequente aumento da for?a muscular respirat?ria, ap?s o TMI com carga moderada. Dessa forma, a adapta??o da musculatura respirat?ria ao treinamento com carga moderada ocorre de forma mais acelerada que a adapta??o do m?sculo perif?rico ao treinamento. TMI com carga de 10% da PIm?x n?o pode ser considerado como dose placebo, pois aumenta a for?a muscular inspirat?ria e TMI com intensidade moderada ? capaz de potencializar o recrutamento de fibras musculares do diafragma e promover sua hipertrofia. O protocolo para realiza??o da Revis?o Sistem?tica foi publicado na The Cochrane Library. / Background: The inspiratory muscle training (IMT) has been considered an option in reversing or preventing decrease in respiratory muscle strength, however, little is known about the adaptations of these muscles arising from the training with charge. Objectives: To investigate the effect of IMT on the diaphragmatic muscle strength and function neural and structural adjustment of diaphragm in sedentary young people, compare the effects of low intensity IMT with moderate intensity IMT on the thickness, mobility and electrical activity of diaphragm and in inspiratory muscles strength and establish a protocol for conducting a systematic review to evaluate the effects of respiratory muscle training in children and adults with neuromuscular diseases. Materials and Methods: A randomized, double-blind, parallel-group, controlled trial, sample of 28 healthy, both sexes, and sedentary young people, divided into two groups: 14 in the low load training group (G10%) and 14 in the moderate load training group (G55%). The volunteers performed for 9 weeks a home IMT protocol with POWERbreathe?. The G55% trained with 55% of maximal inspiratory pressure (MIP) and the G10% used a charge of 10% of MIP. The training was conducted in sessions of 30 repetitions, twice a day, six days per week. Every two weeks was evaluated MIP and adjusted the load. Volunteers were submitted by ultrasound, surface electromyography, spirometry and manometer before and after IMT. Data were analyzed by SPSS 20.0. Were performed Student's t-test for paired samples to compare diaphragmatic thickness, MIP and MEP before and after IMT protocol and Wilcoxon to compare the RMS (root mean square) and median frequency (MedF) values also before and after training protocol. They were then performed the Student t test for independent samples to compare mobility and diaphragm thickness, MIP and MEP between two groups and the Mann-Whitney test to compare the RMS and MedF values also between the two groups. Parallel to experimental study, we developed a protocol with support from the Cochrane Collaboration on IMT in people with neuromuscular diseases. Results: There was, in both groups, increased inspiratory muscle strength (P <0.05) and expiratory in G10% (P = 0.009) increase in RMS and thickness of relaxed muscle in G55% (P = 0.005; P = 0.026) and there was no change in the MedF (P> 0.05). The comparison between two groups showed a difference in RMS (P = 0.04) and no difference in diaphragm thickness and diaphragm mobility and respiratory muscle strength. Conclusions: It was identified increased neural activity and diagrammatic structure with consequent increase in respiratory muscle strength after the IMT with moderate load. IMT with load of 10% of MIP cannot be considered as a placebo dose, it increases the inspiratory muscle strength and IMT with moderate intensity is able to enhance the recruitment of muscle fibers of diaphragm and promote their hypertrophy. The protocol for carrying out the systematic review published in The Cochrane Library.

O consumo de oxig?nio e a frequ?ncia card?aca foram avaliados em repouso e durante os exerc?cios de agachamento com e sem vibra??o a 40 Hz de frequ?ncia e amplitude de 4 mm, de forma aleat?ria com intervalo m?nimo de 24 horas em 18 idosos (15 mulheres e 3 homens, com idade m?dia de 72+6 anos de idade). Para verificar os efeitos da adi??o de vibra??o de todo o corpo ao treinamento com exerc?cios de agachamento, 35 idosos com osteoartrite de joelho, com diagn?stico confirmado por exame cl?nico e radiogr?fico, foram avaliados em tr?s momentos distintos: tr?s semanas anteriores ao in?cio do programa, antes e imediatamente ap?s 12 semanas de interven??o. Os volunt?rios foram alocados aleatoriamente em tr?s grupos: um grupo de interven??o que realizou o programa de agachamento em associa??o com o est?mulo vibrat?rio, promovido pela plataforma vibrat?ria (GPV, N: 12), um grupo exerc?cio que realizou o mesmo programa de agachamento sem vibra??o (GE, N: 11) e um grupo controle que n?o realizou nenhum exerc?cio durante o per?odo do estudo (GC, N: 12). Todos os volunt?rios realizaram quatro testes de desempenho funcional, mensurados de forma direta (Escala de Equil?brio de Berg, Timed Get Up and Go, Teste de Levantar e Sentar na Cadeira e Teste de Caminhada de 6 Minutos), e avalia??o do autorrelato do estado da osteoartrite pelo Western Ont?rio McMaster Universities Osteoarthritis Index (WOMAC). A vibra??o de todo o corpo associada aos exerc?cios de agachamento promoveu um aumento adicional de cerca de 20 % no consumo de oxig?nio e de 7,5 % na frequ?ncia card?aca. Al?m disso, verificou-se que o programa proposto para o GPV aprimorou o desempenho em todos os testes funcionais e em todos os dom?nios do WOMAC. J? o GE apresentou melhora no autorrelato da dor (WOMAC) e aprimorou o desempenho apenas nos testes de Equil?brio de Berg e de Caminhada de 6 minutos. N?o houve mudan?a nos testes de desempenho funcional e nos dom?nios do WOMAC no grupo controle. Embora o est?mulo vibrat?rio tenha intensificado o consumo de oxig?nio e frequ?ncia card?aca durante os exerc?cios de agachamento, esse aumento pode ser insignificante do ponto de vista cl?nico. Al?m disso, a adi??o da vibra??o ao treino com exerc?cios de agachamento melhorou o desempenho funcional e o autorrelato do estado da doen?a em idosos com osteoartrite de joelhos. / Disserta??o (Mestrado) ? Programa Multic?ntrico de P?s-gradua??o em Ci?ncias Fisiol?gicas, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2010. / ABSTRACT Quantify the oxygen consumption and heart rate when vibration is applied to whole body during squat exercises in elderly and investigate the effects of whole body vibration on the functional performance and self-reported disease status of elderly patients with knee osteoarthritis it was the objective this study. The oxygen consumption and heart rate were evaluated in 18 elderly individuals, 15 females and 3 males with a mean age of 72 ? 6 years, who were randomly submitted to 3 experimental situations. The measurements were taken during rest and during the performance of squatting exercises (8 series of 40 seconds with 40 seconds of rest between series; performing squats in 3-second cycles with 10-60 degrees of flexion) without or with vibration at a frequency of 40 Hz and amplitude of 4 mm. To verify the effects of the addition of the whole body vibration to the training with squatting exercises, 35 elderly with knee osteoarthritis, with diagnosis confirmed by clinical exams and radiographic, were evaluated at three different moments: three weeks before initiating training, immediately prior to training and immediately after 12 weeks of intervention, using four functional performance tests [the Berg Balance Scale (BBS), the Timed Get Up and Go Test (TGUG), the Chair Stand Test (CST) and the 6-Minute Walk Test (6MWT)] as well as a self-report from the patients on the status of their disease, assessed using the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC). The participants were randomized into three groups: in the first group, patients performed squatting exercises on a vibrating platform over a 12-week period (vibration group; n=12); in the second group, patients performed squatting exercises without vibration over the same 12-week time period (exercise group; n=11); while the third group of patients were given no exercise training during the study (control group; n=12). Associating whole body vibration with squatting exercises resulted in an additional increase of 20% in oxygen consumption and 7.5% in heart rate in elderly. In addition, whole body vibration training associated with squatting exercises improved performance in all the functional tests and in all the domains of the WOMAC scale. In the exercise group, performance improved BBS and 6MWT and in the pain domain of the WOMAC scale. No change from baseline occurred in any of the tests performed on patients in the control group. Although the vibratory stimulus has increased oxygen consumption and heart rate during squatting exercises, this elicited increase may be insufficient to improve cardiovascular fitness. Moreover, vibration training associated with squatting exercises improved functional performance measured both directly and indirectly in elderly patients with knee osteoarthritis.

Em decorr?ncia do hipoestrogenismo, sintomas caracter?sticos como ondas de calor, sudorese noturna, secura vaginal, dispareunia, ins?nia, altera??es de humor e depress?o, podem ser observados. Ocorre tamb?m o enfraquecimento da musculatura do assoalho p?lvico (MAP), em consequ?ncia da progressiva atrofia m?sculo-aponeur?tica e conjuntiva com consequente deteriora??o da fun??o sexual. Objetivo: Avaliar a for?a da MAP, a fun??o sexual e a qualidade de vida de mulheres climat?ricas. Metodologia: Trata-se de estudo observacional, anal?tico, com desenho transversal. A amostra foi composta por 55 mulheres (35 na p?s-menopausa e 20 na perimenopausa), com faixa et?ria entre 40 e 65 anos, que foram avaliadas por meio do teste de for?a muscular e perineometria. Para a avalia??o da fun??o sexual e da qualidade de vida utilizou-se o Female Sexual Function Index (FSFI) e Utain Quality of Life (UQOL), respectivamente. Para an?lise estat?stica utilizou-se a correla??o de Pearson e an?lise multivariada. Resultados: A m?dia da idade foi de 52,78 (? 6,47 anos). Apresentaram disfun??o sexual 61,8% das participantes (43,62% da p?s-menopausa e 18,17% da perimenopausa). O teste de for?a muscular e o valor m?ximo da perineometria apresentaram uma mediana de 3,00 (Q25: 2 e Q75: 4) e 33,50 cmH20 (Q25: 33,5 e Q75: 46,6), respectivamente. N?o foi encontrada correla??o entre a fun??o sexual e a for?a muscular (r= 0,035; p= 0,802), assim como entre a fun??o sexual e perineometria (r = 0,126; p= 0,358). A m?dia do escore total do UQOL foi de 74,45 (? 12,23). Foi encontrada fraca correla??o positiva entre a fun??o sexual e a qualidade de vida (r= +0,422 p= 0,001). A an?lise multivariada identificou associa??o entre a fun??o sexual e as vari?veis: qualidade de vida, sintomatologia climat?rica, atividade f?sica e n?vel de escolaridade. Conclus?es: Esses resultados sugerem que a sintomatologia climat?rica, a qualidade de vida, a atividade f?sica e o n?vel de escolaridade se associam com a fun??o sexual em mulheres climat?ricas. Entretanto, o componente muscular da fun??o sexual ainda precisa ser mais investigado dentro desse contexto / Introduction: Menopause is characterized by the depletion of ovarian follicles and the gradual decline in estradiol levels, which ends with the definitive cessation of menstrual periods (menopause). As a result of hypoestrogenism, characteristic symptoms, such as hot flashes, night sweats, vaginal dryness, dyspareunia, insomnia, mood swings and depression can be observed. There is also the weakening of the pelvic floor muscles (MAP) as a result of progressive muscle-aponeurotic and connective atrophy with consequent decreased sexual function. Objective: To evaluate the strength of MAP, sexual function and quality of life of menopausal women. Methodology: This is an observational, analytical, cross-sectional design. The sample consisted of 55 women (35 postmenopausal and 20 perimenopausal), aged between 40 and 65, who were assessed by muscle strength and perineometry test. For the assessment of sexual function and quality of life, used the Female Sexual Function Index (FSFI) and Utian Quality of Life (UQOL), respectively. Statistical analysis was performed using Pearson's correlation and multivariate analysis. Results: The mean age was 52.78 (? 6.47 years). Sexual dysfunction presented, 61.8% of participants (43.62% of postmenopausal and perimenopausal 18.17%). Muscle strength test and the maximum perineometry had a median of 3.00 (Q25: 2 e Q75: 4) and 33,50 cmH20 (Q25: 33,5 e Q75: 46,6), respectively. No correlation was found between sexual function and muscle strength (r = 0.035; p = 0.802) and between sexual function and perineometry (r = 0.126; p = 0.358). The mean total score of UQOL was 74.45 (? 12.23). Weak positive correlation was found between sexual function and quality of life (r = +0.422 p = 0.001). Multivariate analysis identified associations between sexual function and variables: quality of life, climacteric symptoms, physical activity and education level. Conclusions: These results suggest that the climacteric symptoms, quality of life, physical activity and level of education are associated with sexual function in menopausal women. However, the muscular component of sexual function needs to be further investigated in this context.

Those conditions have led researchers to investigate alternatives that can favor the quality of life in persons under stress laboral. The present research had as objectives investigate the physiological behavior of parameters (blood pressure, heart hat and respiratory hat) of men and women in condition of stress laboral submitted to the technique Watsu. It was used a experimental methodology with a group formed by men and women in reproductive age, that work as salesclerk in a supermarket net in Natal/RN. The seven individuals selected were submitted to the three phases of the study (dependent groups), that consisted of the phase 1 of obtaining from the measure basal (control 1), in the phase 2 of immersion in the water (control 2), and phase 3 from the application the technique Watsu (experimental phase). It was verified that during the phase basal (condition 1) the physiological parameters (BPS, BPD, HH and RH) of both sexes evaluated showed the medium values of the women (average?detour-standard: BSP = 104.1?7.92; BPD = 70.83 ?7.92; HH = 77.58 ?3.87; RH = 19.83 ?2.58) similar those presented by the men (BPS = 118.75 ?7.55; BPD = 75.00 ?9.91; HH = 71.75 ?14.95; RH = 16.62 ?3.99). The evaluation of those parameters before and after immersion of the volunteers in the water (condition 2) showed a significant reduction (W = 3.0: p&#8804;0.05) barely for the values of BPS presented by the sex females after immersion. In the men group, all of the physiological parameters analyzed did not vary significantly. Regarding the profile of those variables before and after application of the watsu (condition 3), was verified a significant increase (W= 0,0: p&#8804;0.05) for the BPS one and SABP in the women. The Men did not show significant variation for all of the physiological parameters. Faced with the results presented, we are able to conclude that the systolic and diastolic blood pressures were the physiological parameters that are on influence from the Technique Watsu, only for the kind females / As varia??es de par?metros fisiol?gicos em situa??o de estresse laboral podem funcionar como indicadores no surgimento de desordens. Essas condi??es t?m levado pesquisadores a investigar alternativas que possam favorecer a qualidade de vida em pessoas sob estresse laboral. O presente estudo teve como objetivo Investigar o comportamento de par?metros fisiol?gicos (press?o arterial, freq??ncia card?aca e freq??ncia respirat?ria) de homens e mulheres em condi??o de estresse laboral submetidos ? t?cnica Watsu. Utilizou-se uma metodologia experimental com popula??o formada por homens e mulheres em idade reprodutiva que exercem a fun??o de operadores de caixa, numa rede de supermercados em Natal/RN. Os sete indiv?duos selecionados foram submetido ?s tr?s etapas do estudo (grupos dependentes), que consisti na fase 1 de obten??o da medida basal (controle 1), na fase 2 de imers?o na ?gua (controle 2), e fase 3 da aplica??o da t?cnica Watsu (fase experimental). Foi verificado que durante a fase basal (condi??o 1) os par?metros fisiol?gicos (PAS, PAD, FC e FR) de ambos os sexos avaliados mostrou os valores m?dios da mulheres (m?dia ?desvio-padr?o: PAS = 104.1 ?7.92; PAD = 70.83 ?7.92; FC = 77.58 ?3,87; FR = 19.83 ?2.58) semelhantes ?queles apresentados pelos homens (PAS = 118.75 ?7.55; PAD = 75.00 ?9.91; FC= 71.75 ?14.95; FR=16.62 ?3.99) . A avalia??o desses par?metros antes e aos a imers?o dos volunt?rios na ?gua (Condi??o 2) mostrou uma redu??o significativa (W=30:p&#8804;0,05) apenas para os valores de PAS apresentado pelo sexo feminino ap?s a imers?o. Entre os homens, todos os par?metros fisiol?gicos analisados n?o variaram significativamente. Com rela??o ao perfil dessas vari?veis antes e ap?s aplica??o do Watsu (condi??o 3), foi verificado um aumento significativo (W=0,0: p&#8804;0.05) para a PAS e PAD nas mulheres. J? os homens, n?o mostraram varia??o significativa para todos os par?metros fisiol?gicos. Diante dos resultados apresentados, pode-se concluir que as press?es arteriais: sist?lica e diast?lica foram os par?metros fisiol?gicos que sofreram influ?ncia da T?cnica Watsu, apenas para o g?nero feminino
