The Family Health Strategy facilitates user access to mental health actions. This study aimed to verify the community health agents’ perceptions of the Family Health Strategy about mental disorder. A qualitative study was conducted with 26 randomly selected community health agents, among the professionals of 13 units, which constitute the Family Health Strategy of Itapeva (SP). The community health agents responded to a personal information questionnaire and a semi-structured interview. Data were checked through content analysis. Stigmatizing perception of the mentally disturbed persons, lack of knowledge about the process of falling ill and the mental disorder evolution, and the unpreparedness to act in this population were observed. Capacitating agents enable them to contribute in a positive way to the effective functioning of a care net in mental health in the city.

Adopting a healthy lifestyle it is critical for the prevention of high blood pressure and is an indispensable part of the treatment of those with hypertension. High levels of physical activity and greater fitness are associated with reduced incidence of hypertension. However until the beginning of the 1990 decade, the resisted exercise was not inclued at the internacionals statements for people with heart disease. Fortunately, in the past few years, this type of exercise started to take into account as a possible strategy for the first and second prevention of diferents cardiovascular diseases. The aim of this study it is to evaluate, through a systematic review, the contribution of the resisted exercise on the cardiovascular responses in hypertensive male adults. Twenty eight articles were pre-selected for this study, four attend to the requirements. The results were not consistent in this review, only the diastolic blood pressure demonstrated decrease in three of the four studies, in circuit protocol as much as in the conventional protocol. Otherwise one study proved an increase in the VO2max, wich is an important data, because it is an anaerobic exercise and, an improve was not expected. An other article analised the harm issues of the Valsalva manouvre, where it was presented the maximum blood pressure values (345/245 mmHg) and evidences of lower blood pressure rises in the intra-arterial, intrathoracic and intra-abdominal pressures when the exercise was performed without the manouvre, enhancing the necessity to avoid the use of this manouvre in hypertensive individuals.

Inflammation is an immune complex-related tissue damage and / or cell caused by chemical, physical, immunological or microbial. The inflammatory process involves a complex cascade of biochemical and cellular events, including awareness and receptor activation, lysis and tissue repair. In general, tissue damage trigger a local inflammatory response by recruiting leukocytes, which release inflammatory mediators. These substances are able to sensitize nociceptors. After synaptic transmission and signal modulation by nociceptive sensory neurons, these signals are perceived as pain. Pain is an experience that involves multiple factors. The route of the supraspinal pain control originates in many brain regions, such as substance periarquedutal gray (PAG), median raphe nucleus and rostral ventromedial medulla (RVM) and have a critical role in determining the chronic and acute pain. Anti-inflammatory drugs (NSAIDs) are used to control inflammation, which inhibit the inflammatory mediators, but can cause side effects such as stomach ulcers and cardiovascular damage. An alternative for the treatment of pain and inflammation is the use of plant species. The genus Eugenia belongs to the family Myrtaceae, one of the largest botanical families of expression in the Brazilian ecosystems. From the pharmacological point of view, studies of similar species crude extracts showed the presence of anti-inflammatory, analgesic, antifungal, hypotensive, antidiabetic and antioxidant activity of some species. As a class of importance in therapeutic phytochemical, the flavonoids has represented an important group with significant anti-inflammatory and gastroprotective, and are present in a significant way in the chemical composition of genus Eugenia. The project´s overall objective is to evaluate the antinociceptive and anti-inflammatory activities from hydroalcoholic extract of leaves of Eugenia punicifolia (EHEP). In this work we performed acute toxicity ...

O câncer colorretal (CCR) é a terceira causa mais comum de câncer no mundo em ambos os sexos e a segunda causa em países desenvolvidos. Seu tratamento convencional é baseado na cirurgia associada à radioterapia e à quimioterapia em dose máxima tolerável, para tentativa de eliminação massiva das células tumorais. Tal abordagem, no entanto, pode causar efeitos colaterais importantes, entre eles as alterações hematopoiéticas e a supressão da resposta imune. As vacinas de células dendríticas mostram-se como opção terapêutica promissora para muitos tipos de câncer, havendo diferentes protocolos de preparação e sensibilização dessas células para dirigir a resposta antitumoral específica. Alguns agentes antineoplásicos em doses ultrabaixas mostraram modular positivamente as células dendríticas (DCs) e, na célula tumoral, promover alterações na transcrição de vários genes imunologicamente relevantes. Considerando que, em estudos prévios, tais mudanças transcricionais resultaram em aumento de imunogenicidade das células tumorais, hipotetizamos que o RNA das células pré-tratadas deve ser mais eficiente do que o RNA das células originais para preparação de vacinas de células dendríticas. Assim, objetivamos avaliar se o tratamento de células do tumor de cólon humano (HT-29) com PAC ou 5-FU/LEUCO torna seu RNA mais eficiente para preparação dessas vacinas. Para essa investigação, DCs humanas geradas a partir de monócitos de sangue periférico foram transfectadas com RNA total das células tumorais pré-tratadas e, a seguir, testadas quanto à capacidade de apresentação de antígenos e indução de células T citolíticas específicas. Apesar da baixa viabilidade celular pós eletroporação, os resultados obtidos sugerem que o tratamento de células tumorais com concentrações não tóxicas de 5-FU ou PAC promove alteração de expressão...

A formação do trombo arterial, composto predominantemente por plaquetas, se dá sob condições de estresse de cisalhamento elevado, nos locais de lesão aterosclerótica vascular e fluxo sanguíneo perturbado e tem como consequência diminuição ou obstrução do calibre dos vasos dos diferentes órgãos podendo levar a eventos isquêmicos. As doenças cardiovasculares são consideradas as principais causas de morte no mundo. Nesse contexto, estima-se que a aterosclerose/aterotrombose seja a causa primária de doença arterial coronariana e acidente vascular cerebral representado mais de 50% das causas de mortes em países ocidentais . É sabido que a aterosclerose, primeiro evento que predispõe à aterotrombose, é considerada um processo inflamatório crônico, e que a utilização de antiinflamatórios não esteroidais (AINEs) COX-1, melhor estabilizam a estrutura da placa ateromatosa impedindo o rompimento e a consequente formação do trombo. Neste contexto, no presente trabalho foram obtidos de novos candidatos a fármacos com propriedades doadoras de NO e antiagregantes plaquetárias, através da estratégia de hibridação molecular dos AINEs contendo uma subunidade doadora de óxido nítrico, representada pelos furoxanos, e espaçada por uma subunidade N-acil hidrazônica. Dessa forma, a inibição da síntese de tromboxanos associada à doação de óxido nítrico permitiu atuação nas plaquetas através de um mecanismo múltiplo de ação com fins de diminuição da agregação plaquetária. Os produtos intermediários e finais apresentaram bons rendimentos e foram caracterizados por técnicas analíticas as quais predisseram que as estruturas propostas foram obtidas. Todos os compostos se como doadores de óxido nítrico. Os compostos 1a e 3a apresentaram atividade analgésica superior a dipirona, utilizada como controle. No ensaio de agregação plaquetária ―in vitro‖... (Resumo completo, clicar acesso eletrônico abaixo)

The research aims to analyze the main changes in the concepts of the processes of production and consumption of news content information. The theoretical framework used will be the new consequent social, economic and technological paradigms of the current scenario of convergence of platforms, content and languages. The research aims to investigate the changes in the macro environment of journalistic production and, therefore, examine whether the local flow of news content meets the requirements of a new public consumption target set by the new Brazilian generations, composed of young people influenced by the cultures of computing, audiovisual communication and also by economic and cultural globalization. As expansion of the analyzes sought to verify the impact of these changes in the current models of traditional media, as well as the interference caused and trends in models of existing production. Also a case study is performed on this production flow in comparison with current market research of Jornal da Cidade (JC) of the city of Bauru (SP), the main media of the Grupo Comunicação. The intent of the approach will be to establish some preambles to assist in bringing the theory with the practical impacts on journalistic production, its agents, institutions and the workplace

Plumbism is considered the oldest occupational disease. Among the pathophysiological effects associated with lead (Pb) are cardiovascular disorders. Many diseases that develop later in life are determined during the early stages of life, under the influence of exposure and preferred diet of the mother. Still, one should consider that many environmental contaminants at levels not harmful can determine pathophysiological processes if physical or chemical stressors and/or pathological conditions are present. In this context, the intrauterine malnutrition may represent an additional risk factor in exposure to Pb during pregnancy and lactation. For these reasons, the objective of this study was to evaluate the cardiovascular risk of weaned rats that have suffered perinatal exposure to Pb and intrauterine malnutrition, alone or in combination. After mating, female rats were divided into control (ctrl, ad libitum), food restriction (RA, the same diet 50% of consumption in the control group during pregnancy), exposed to Pb (500 ppm Pb in drinking water during pregnancy and lactation) and association (As, received the last two procedures in combination). Cumulative concentration-effect curves (CECs) to CaCl2 and noradrenaline (NA) were obtained in rings with and without endothelium of the same thoracic aorta from male weaned rats (23-25 days old). Maternal weight, litter weight, weight and number of pups at birth, anogenital distance, arterial blood pressure (ABP) and weight of tissues (kidney, liver, aorta, left ventricle) were evaluated. Changes in vascular reactivity were assessed by the maximum response (MR) and 50% effective concentration (EC50). Data were presented as mean ± SEM. Statistical analysis was performed by multifactorial analysis of variance and Tukey's post test. Body weight of dams did not differ between the experimental groups, except on the...(Complete abstract click electronic access below)

Our previous studies have shown that low concentrations (noncytotoxics) of antineoplastic agents modulate positively the dendritic cells, favoring their in vitro maturation and improving their antigen presenting function. The effects on colorectal cancer cells (HCT-116) were also investigated and we have observed an increased immunogenicity and susceptibility to cytotoxic T cells. Thereby, this study aimed to investigate the effect of 5-fluorouracil (5-FU) an azacitidine (AZA), in minimum effective and noncytotoxic concentrations on lymphocytes of healthy donors. In this study we have analyzed the cytotoxic effect of drugs at these concentrations as well as the proliferative ability of lymphocytes. In vitro production of IL-10 and IFN-γ has been also evaluated. We have observed that low concentrations of those chemotherapeutic agents are not cytotoxic for lymphocytes. However, the minimum effective concentrations (5-FU: 0,410±0,088 e AZA: 0,757±0,233; p<0, 05) have reduced the cell number. Proliferative activity of allogeneic lymphocytes in a mixed reaction (MLR) was not affected by the treatment. The cytokine production was not affected by the treatments, either. In conclusion, low concentrations of 5-FU and AZA has no deleterious effects on human peripheral blood lymphocytes and seems to be safe for combinatory administration with DC vaccines
