Examine the effects Global Postural Reeducation, (GPR) in hyperkyphosis and respiratory variables in the elderly was the objective in the research. For this, two elderly participated, one is 62 years old (voluntary 1) and another is 66 years old (voluntary 2), without lung, heart, kidney and/or skeletal-muscle diseases diagnosed. The volunteer have been assessed for Quality of Life (QOL) through the questionnaire SF-36, the degree of toracic kyphosis, the muscular respiratory strength and the thoracic-abdominal mobility. The GRP treatment consisted in eight sessions applied, once one hour each session. After the eight sessions the volunteer were reevaluated. The data concerning assessments before and after treatment were analysed describly. According to the results there was an improvement in the degree of kyphosis in both volunteers, highlighting voluntary 2. Respiratory variables also improvements after treatment. In relation to the Quality of life in most areas there has been an increase in scores indicating improved QOL. These data showed that the GPR has been effective to decrease the level of kyphosis, improves respiratory variables and the quality of life in the elderly treated. However, further work with a greater number of subjects must be carried out to analyze the effectiveness of therapy in the elderly.

Introduction: The pulmonary rehabilitation (PR) is composed of aerobic and resisted exercises that improve the functional capacity to the exercise, life quality and decrease respiratory symptoms in subjects with chronic pulmonary disease. Objective: Assess the effects of a combined PR program in the cardiorespiratory function and peripheral muscle strength in subjects with chronic pulmonary disease. Method: Patients with chronic pulmonary disease were submitted to the PR program, which was developed on 24 sessions of 60 minutes (three times per week). The program was composed of aerobic exercises (two times per week) and resisted exercises (once a week). Before and after the PR the patients were submitted to manovacuometry in order to measure the maximum inspiratory pressure (MIP) and the maximum expiratory pressure (MEP), ventilometry, peek expiratory flow (PEF), six minute walking test (6MWT) and one maximum repetition (1RM). The data are presented in absolute frequency, percentage and mean±standard deviation. The t Student test was used to compare data before and after the PR and the ANOVA test to compare before, after and predicted distances in the 6MWT (p<0.05). Results: Seven patients were part of this study, 85.70% of women, 71.40% with pulmonary emphysema diagnosis. The mean age was 69.43±5.59 years old, the height was 1.61±0.07 m, the mean weight was 66.20±8.40 kg and the body mass index mean was 25.50±2.48 kg/m². From the variables assessed, the MEP increased from 79.71±13.69 to 84.42±12.83 cmH2O (p=0,03), the PEF increase from 255.71±66.3 to 320.00±93.63 l/min (p=0,03) and the distance in the 6MWT from 415.28±47.90 to 483,79±79,77 m (p=0,02). The load in the 1RM test in the reverse peck deck exercise (before - - 17.10±8.10kg; after – 210.40±9.00kg), knee in leg extension machine (before – 17.10±9.50kg; after – 26.40±13.10kg) and hip extensors (right before – 48.60±22.10kg; after – 62.90±19.30kg; and left before – 46.40±20.10kg; after – 62.10±18.20kg) increased significantly (p<0,05). Conclusion: After the PR program there was improvement in the expiratory muscular strength, in the lower limbs strength and in the functional capacity. Besides that, there was a reduction in the airflow obstruction of the subjects with chronic pulmonary disease.

Introduction: Obesity is a risk factor for postoperative pulmonary complications. Overweight can alter respiratory mechanics and decrease lung volumes and capacities. Bariatric surgery (BS) has been used as treatment for morbid obesity, but this surgery can lead to respiratory complications. Objective: To evaluate pulmonary function in morbid obese patients undergoing bariatric surgery. Methods: The patients were submitted to pulmonary function testing, including slow and forced vital capacity (SVC and FVC), forced expiratory volume in the first second (FEV1), Tiffenau index (FEV1/FVC), forced expiratory flow 25-75% (FEF25-75%) and maximal inspiratory and expiratory pressure (MIP and MEP). Descriptive analysis was performed. Results: We evaluated 18 patients, mean age of 37.33 ± 11.23 years, height 1.65 ± 0.09 m, weight 125.92 ± 25.24 kg and BMI 46.34 ± 9 20 kg/m2 , SVC 100.64 ± 22.91%, FVC 102.04 ± 21.82%, FEV1 104.85 ± 22.16%, FEV1 /FVC 83.54 ± 6.63% and FEF25-75% 84.47 ± 25.74%, 99.75 ± 24.55 for MIP and MEP 102.12 ± 25.06 cmH2O. Conclusion: The bariatric surgery candidates had normal values for manovacuometry and spirometry.

A novel AC Biosusceptometry (ACB) system with thirteen sensors it was implemented and characterized in vitro using magnetic phantoms. The system presenting coils in a coaxial arrangement with one pair of excitation coil outside and thirteen pairs of detection coils inside. A first-order gradiometric configuration was utilized for optimal detection of magnetic signals. Several physical parameters such as baseline, number of turns, excitation field and diameters were studied for improvement of the signal/noise ratio. This system exhibits an enhanced sensitivity and spatial resolution, due to the higher density of sensors/area. In the future those characteristics will turn possible to obtain images of magnetic marker or tracer in the gastrointestinal tract focusing on physiological and pharmaceutical studies. ACB emerged due to its interesting nature, noninvasiveness and low cost to investigate gastrointestinal parameters and this system can contribute for more accurate interpretation of biomedical signals and images

Silicosis, a common type of pneumoconiosis, is an occupational lung disease caused by inhalation of silica dust often with mining activity and thus reaches the miners. The fine and ultrafine silica particles deposited in the alveolar epithelium may lead to the development of progressive massive fibrosis. An increased reactive oxygen species (ROS) production has been proposed to explain the mechanism for induction of pulmonary fibrosis in silicosis. In this situation, alveolar macrophages are activated to phagocytes silica particles deposited in the alveoli. The activated macrophages secrete large amounts of ROS that in turn induce synthesis of fibrotic factors. In addition, the activity of antioxidant enzymes is impaired, which results in increased lipid peroxidation, as well as generating a local inflammatory process. Diffuse pulmonary fibrosis progresses with interstitial collagen deposition. Interstitial collagen overlies small pulmonary arteries and arterioles and thus it is associated with pulmonary hypertension in pulmonary fibrotic diseases. In addition, cytokines and silica particles passing through the respiratory membrane can reach the bloodstream. In this context, the increase in the generation of ROS in the circulation may lead to a reduction in the bioavailability of nitric oxide, an important endothelium-derived relaxing factor. A deficiency in the nitric oxide bioavailability can result in vascular endothelial dysfunction. Moreover, pro-inflammatory cytokines could contribute to the impairment of endothelial function. In the airways, pro-inflammatory cytokines can reduce the smooth muscle responsiveness to β- adrenergic agonists as isoproterenol. Thus, the aim of this study was to evaluate the effect of silica dust instillation in the function of the pulmonary artery, aorta and trachea of rats with acute silicosis. For this purpose, male Wistar rats were anesthetized... (Complete abstract click electronic access below)

Combining the characteristics of good adhesion and sealing of the AH Plus sealer the biological properties of the MTA, zinc oxide and calcium hydroxide, the purpose of this study was to evaluate the cytotoxicity of these associations. The specimens of the sealers and their associations were mixed and exposure to culture medium (82.4 mm2surface/mL) after the manipulation and incubated in a humidified incubator (37°C and 100% humidity) for 24 h. Chinese hamster lung fibroblasts (V79) were exposed to different dilutions of this extracts for 24 h and cell viability was measured by MTT test. The differences between the cell survival rates were statistically analyzed for Kruskal-Wallis and Dunn (p≤0.05). All sealers showed a significant difference with the group control, except the MTA. Cytotoxicity with the control group increased in the following order: AH Plus < AH Plus + Ca(OH) 2 < AH Plus + OxZn< AH Plus + MTA < MTA (p≤ 0,05). It was concluded that the addition of biological materials in order to improve the consistency of AH Plus for use in retro cavities its toxicity has not decreased significantly

Segundo a Organização Mundial da Saúde, em países de baixa renda as infecções do trato respiratório ocupam o primeiro lugar dentre as causas de morte, sendo responsável por 11,2% das mesmas. Dentre estas, a causada por Streptococcus pneumoniae é uma das responsáveis pelo maior número de mortes em crianças ou adultos acometidos por doenças pulmonares crônicas. No pulmão os macrófagos alveolares (MAs) através de receptores expressos na superfície celular, como receptores “scavenger”, possuem um papel crítico na fagocitose e atividade microbicida de diferentes bactérias Gram-positivas. Em indivíduos acometidos por doenças pulmonares crônicas há um grande acúmulo de células apoptóticas (ACs) e estes podem ser mais susceptíveis a infecções pulmonares bacterianas como por S. pneumoniae. A presença destas ACs poderia contribuir para o aumento desta susceptibilidade através da supressão da resposta imune. Portanto, neste trabalho avaliamos se o efeito supressor mediado por ACs pode interferir na modulação das atividades microbicidas de MAs contra S. pneumoniae via receptores “scavenger”. A partir dos resultados encontrados, pode-se sugerir que 1) a eferocitose por MAs possui efeito imunossupressor na atividade microbicida contra S. pneumoniae; 2) a atividade supressora mediada pela fagocitose de ACs por MAs foi inibida na presença de bloqueadores de SR-A, sugerindo que os SR-B I/II são menos sensíveis a efeito supressor decorrente da eferocitose; 3) a PGE2, oriunda da eferocitose, liga-se ao receptor EP2 e suprime a atividade microbicida de MAs; 4) as produções de IL-1α, TNF-α e NO estão aumentadas na presença de ACs, sugerindo que a eferocitose por MAs promove um descontrole na ativação de MAs mediante a infecção por S. pneumoniae

Staphylococcus is one of the more important causes of the called Foodborne Disease(FD), being that from the 40 species described from genus, the more important is Staphylococcus aureus. During years believed that the S. aureus was the only specie from genus able to produce enterotoxins, responsable for the clinical frame in humans, but latest studies report the isolation of other species both positive coagulase (PC) as negative with enterotoxigenic potential. The symptoms of this intoxication appear after a short period of incubation (2-6 hours) and usually characterized by nausea, vomits, abdominal ache, diarrhea, and rarely is fatal. For the toxin to be formed in food is necessary that bacteria population to be at least 105 UFC/g, being that such toxins characterized by presenting great resistance front of gastrointestinal proteases and of homemade termical treatment. Among the main foods that might carry the microorganism, the milk and its derivatives have highlights. The contamination of the product might happen as from the milk from cows with clinical and/or subclinical mastitis, as the Staphylococcus genus is one of the main agents etiologic from this disease, equipments utensils badly sanitized equipments and utensils and from the manipulators. The control of these factors configures as fundamental condition for the achievement of a safe, quality product, which doesn’t offer risk to the consumers

O uso de plantas medicinais especialmente na América do Sul contribui significativamente para os cuidados básicos com a saúde. Para o tratamento de infecções comuns, muitas plantas são utilizadas no Brasil na forma de extrato bruto, infusões ou emplastros, sem nenhuma evidência científica de sua eficácia (PESSINI et al., 2003). AYRES et al. (2008) afirma que a busca de substâncias com atividades antimicrobianas tem direcionado a atenção sobre os produtos naturais e, entre estes, os derivados das plantas superiores têm, nos últimos anos, despertado a investigação para o potencial da flora brasileira. Byrsonima pachyphylla Griseb é uma árvore típica do cerrado. Na medicina popular, a casca é utilizada como antifebril, contra tosses e doenças pulmonares, os ramos com folhas são diuréticos e os frutos são laxantes brandos (SILVA JÚNIOR et al., 2005). Levantamento no NAPRALERT indicou que espécies deste gênero são comumente empregadas como antiasmáticas, contra a febre e infecção de pele (MENDES et al., 1999). Este trabalho teve como objetivo determinar qual o melhor método de extração, sendo eles a maceração, a maceração dinâmica, a digestão e a digestão + maceração dinâmica, visando à obtenção de extratos brutos de folhas de Byrsonima pachyphylla Griseb., considerando sua atividade biológica frente a bactéria Gram-positiva: Staphylococcus aureus; as bactérias Gram-negativas: Escherichia coli e Pseudomonas aeruginosa, e a levedura Cândida albicans, testada pelo método de diluição seriada de extratos em microplacas; além de comparar perfis cromatográficos dos extratos obtidos em cromatografia de camada delgada (CCD), bem como pesquisar as principais classes de metabólitos secundários nos extratos. Os resultados obtidos na cromatografia em camada delgada e na triagem fitoquímica preliminar possibilitaram sugerir a presença de taninos, flavonoides, terpenos e saponinas na espécie ...

A contaminação do solo pelo descarte de substâncias tóxicas adquiriu, nos últimos anos, maior atenção da comunidade científica a qual tem alertado a população dos países, em geral, para as conseqüências, em especial, as patologias que podem ocorrer quando estas substâncias adentram nossa cadeia alimentar. Neste trabalho procurou-se apresentar as fontes de contaminação e a toxicidade do cádmio, do chumbo, do mercúrio e do manganês, quando estes se encontram em níveis elevados no solo e nos mananciais superficiais e subterrâneos. Com relação aos três primeiros metais, sua alta dosagem pode provocar, no ser humano, diversos tipos de câncer, lesões no estômago e pulmões, além de alterações importantes nos sistemas imunológico e nervoso central. O manganês, um dos metais mais comuns da crosta terrestre, largamente utilizado pela indústria e disponibilizado, em grandes quantidades no meio ambiente, em doses elevadas pode causar doenças pulmonares e neurológicas.

The research discusses the pulmonary function of the students of SORRI that are part of the Project for the extension of the Department of Physical Education in Bauru Swimming for People with Disabilities during the aquatic activities, noting the changes in efficiency class of breathing with the practice of aquatic activity, by the analysis of the volume and respiratory capacity. The respiratory control is essential in the process of adaptation to the liquid medium, because a student who fails to immerse the face in the water will not be able to adopt a horizontal position sufficiently stable. The practice of aquatic activities requires a great effort of breathing. Therefore, the practice of aquatic activities influence favorably the breathing, because the movements performed in the water tone the diaphragm, which is the essential muscle of the breathing, allowing an improvement in pulmonary ventilation. For the purposes of this study, the sample was composed of 10 students of the SORRI of the city of Bauru forming part of the project Swimming for People with Disabilities, practicing swimming once a week for 1 hour. For the collection of lung volumes and capacities was used a transducer of air flow and a unit of data collection, model MP36, both of the brand Biopac connected to a computer, where the data were collected and recorded for later analysis. Two tests were carried out in a day with each participant in the project of swimming, and a test at the beginning of the lesson, at rest, and another after a series of 10 breaths carried out within the swimming pool. These tests were performed in the months of March and April. The analysis of the data was through the medium of the figures and also individually, noting the changes in respiratory function of students practicing aquatic activities, without which there would be no comparison between the participants. The measurements of the scores on the pre- and post-exercise show that the...
