The literature suggests an association between drug use and addiction and the repertoire of social skills of the individual. However, there are still relatively few studies focusing specifically on the relationship between smoking and social skills. Moreover, Brazilian studies on the subject are scarce. This paper presents a review of the literature about smoking and social skills, emphasizing the theoretical underpinning research, as well as the main data obtained so far. One of the most investigated issues is the relationship between assertiveness and smoking. It is assumed that the lack of assertiveness and in particular the ability to refuse the supply of drugs and / or peer pressure to consumption can be a risk factor for smoking initiation, especially in adolescents. However, the literature on this issue is still controversial. It is assumed that further studies to elucidate these associations could contribute to prevention programs and intervention for tobacco use, using social skills training as a strategy.

Radiotherapy is a field of medical physics, which has been going through a scientific and technological advancement, it is extreme important the professionals that work in this area continuous their study to improve the quality of service provided. For it, they should know the physical principles related as well their employment in radiotherapy. The electrons have been using in therapy of superficial tumors, because they show rapid decrease of dose in depth, they don’t expose the deeper tissues to radiation. The electron therapy has replaced the surface therapy with x-ray and mold brachytherapy, and nowadays, it represents 10 to 15% of radiotherapy treatments. This study brings the definition of physical parameters used in the dosimetry of electron beam, describes the tests for quality control of linear accelerator with a electrons beam, as well the activities realized in the Radiotherapy Division, of Hospital de Clinicas, in the Universidade Estadual of Campinas, in the Clinac 2100C machine

Complementary and alternative medicine (CAM) is becoming increasingly popular, and despite of the growing demand for these practices, physicians and CAM-providers work separately and there is no sufficient effort in the promotion of an integrative health care. Questions like differences of concepts and language, lack of scientific evidence through randomized clinical trials, no regulation of CAM-providers, products and services, besides the lack of government policies in this scope, turn the process of integration difficult and threaten the quality of delivery of health care. Through the integrative review method, the purpose of this paper is to discuss the issues involved in the integration process of complementary and alternative medicine into the conventional health care systems (guided by principles of biomedicine), addressing benefits and risks, obstacles to integration and models of integration in the discussion topicsl

As úlceras gástricas, além de representarem eventos patológicos comuns na clínica médica, são atualmente consideradas importantes desafios para a terapêutica, à medida que o tratamento e/ou prevenção dessa doença ainda apresentam limitações, como os efeitos adversos e a baixa qualidade de cicatrização. Outro grande problema é a difícil acessibilidade às terapias disponíveis pela população de baixa renda, devido ao seu alto custo. Considerando a problemática abordada, e levando em consideração que estudos têm mostrado que terpenóides têm apresentado atividade antiúlcera bastante significativa, propusemos investigar o efeito gastroprotetor do monoterpeno Citral em úlceras gástricas experimentais induzidas tanto por etanol quanto por antiinflamatórios não esteroidais (utilizando a Indometacina como agente indutor das ulcerações), bem como avaliar seu efeito cicatrizante. O Citral mostrou ser gastroprotetor frente ao agente lesivo etanol, a partir da dose de 25 mg/kg, em uma relação dose-dependente quando administrado oralmente, sendo mais potente do que a Carbenoxolona, utilizada como controle positivo, a partir de uma dose duas vezes menor [dose de 50 mg/kg, na qual o Citral apresentou 98 % de proteção em relação ao controle negativo (Tween 80 a 8%), contra 85 % de proteção proporcionada pela Carbenoxolona na dose de 100 mg/kg]. No entanto, no modelo de indução de úlceras gástricas por Indometacina o Citral mostrou um efeito dual, ao passo que em doses intermediárias (25 e 50 mg/kg) apresentou efeito gastroprotetor, e em doses extremas (100 e 200 mg/kg) apresentou uma significativa potencialização das lesões, permitindo assim a hipótese de um possível efeito antiinflamatório e/ou antinociceptivo nessas doses. Também foi verificado seu efeito cicatrizante na dose de 25 mg/kg, sendo tão eficaz quanto o Lansoprazol (controle positivo)... (Resumo completo, clicar acesso eletrônico abaixo)

A leishmaniose é um conjunto de doenças infecciosas causadas por parasitas do gênero Leishmania, que afligem milhões de pessoas no mundo, tendo a cada ano dois milhões de novos casos e 70 mil mortes. As drogas utilizadas no tratamento das diferentes formas clínicas da doença apresentam alta toxicidade e baixa eficácia, além de apresentarem muitos efeitos colaterais e colaborarem com o aparecimento de parasitas e vetores resistentes. Devido a estas adversidades, o desenvolvimento de novas terapias para o tratamento desta parasitose é incentivada pela Organização Mundial da Saúde (OMS) e um maior conhecimento sobre a biologia molecular destes protozoários poderá facilitar estas descobertas. Ultimamente, os telômeros, estruturas nucleoproteícas nos terminais dos cromossomos de eucariotos, têm sido alvo intenso de estudos, que visam utilizá-los como alvo terapêutico contra tumores malignos e microrganismos patogênicos. Os telômeros geralmente se apresentam como estruturas dinâmicas onde ocorrem interações entre o DNA e proteínas, resultando na formação do complexo telomérico, que é responsável pela proteção e manutenção dos cromossomos e estabilidade do genoma, caracterizando uma função imprescindível para viabilidade celular. Componentes do complexo telomérico de Leishmania amazonensis foram identificados por ensaios bioquímicos em extratos positivos para a atividade de telomerase. Entre estes componentes identificou-se as proteínas LaRPA-1 (L. amazonensis Replication Protein A-1) e a LaRbp38 (L. amazonensis RNA binding protein) as quais mostraram habilidade de interagir com o DNA telomérico in vitro e in vivo. Mais recentemente, utilizando-se ensaios de imunoprecipitação e de captura por “pull-down” foi demonstrado que estas proteínas fazem parte de um mesmo complexo nos telômeros do parasita. Este trabalho pretende confirmar estas possíveis interações entre as proteínas teloméricas LaRPA-1 e ...

This study will focus on one part of Traditional Chinese Medicine (TCM), acupuncture - utilized as therapy method for pathologies treatment in humans and animals - , as well as its main techniques. Acupuncture is one branch of TCM, originated from theoretical and empirical knowledge accumulated by popular medicine. Currently, researches performed in humans and animals have shown the effectiveness of this method as an assistance or alternative in illnesses treatment. Besides that, professionals are not merely looking for orthodox medicine knowledge, but also specializations and improvement over the complementary therapies area. There are diverse studies and researches which were and are being done in veterinary, relating the effectiveness of acupuncture in small and large animals. In comparison, in the wild animals’ area the numbers of studies is smaller. However, it is expected that this number increases over the fact that some of these animals’ species are entering the pet market and also because of the possibility of using these methods for treatment and prevention of diseases on zoo animals or other animals kept in captivity

O mieloma múltiplo (MM) é uma neoplasia maligna secundária à expansão clonal de células plasmáticas caracterizada pela presença de imunoglobulina monoclonal no sangue e/ou na urina, lesões líticas ósseas e infiltração de plasmócitos monoclonais na medula óssea. A caracterização dos mecanismos responsáveis pela expansão das células tumorais do MM é difícil e envolve uma série de alterações genéticas e mudanças no microambiente da medula óssea, favorecendo o crescimento do tumor e a falha do sistema imune em reconhecê-lo. O MM é uma doença incurável, sendo a sobrevida mediana dos pacientes em torno de 3-5 anos. Terapias atuais como quimioterapia e transplante autólogo de células-tronco podem induzir remissão da doença, mas a recaída e a morte são inevitáveis. Os antígenos específicos câncer/testículo (CTs) foram originalmente descritos em pacientes com melanoma e são assim denominados, pois suas proteínas foram identificadas em espermatogônias, células conhecidas por não expressarem antígenos de histocompatibilidade (HLA), o que as impossibilita de desencadear uma resposta imune específica. Esses antígenos foram identificados posteriormente em vários tipos de tumores humanos, como melanoma, carcinoma pulmonar, câncer renal, entre outros. Até o momento, existem poucas informações a respeito de sua importância como fatores de prognóstico clínico ou relacionado à proliferação aberrante das células plasmáticas. Assim, o objetivo deste estudo é avaliar o nível de expressão gênica dos antígenos câncer/testículo MAGEC1(CT7), MAGEA3/6, LAGE-1, NY-ESO-1 e GAGE em amostras de aspirado de medula óssea total de pacientes com mieloma múltiplo. A análise de expressão por RT-PCR dos 5 CTs de interesse, realizada em 21 amostras de medula total de pacientes com MM, demonstrou as seguintes freqüências: CT7 (42,9%), LAGE-1 (23,8%)...

A monoclonal antibody (mAb) is an important tool in medical biotechnology and the production of biopharmaceuticals, especially for disease diagnosis and treatment of infections, because the antibodies have a significant advantage over chemical agents used in conventional therapies . The last thirty years the technology of production of monoclonal antibodies developed mainly the technique of obtaining in vitro, but also of their production is laborious, the cost is high. A major element of the high cost of production is the fact that the long-term culture consumes a large amount of imported inputs with high added value. A major contribution of this work is to promote cell growth more quickly and efficiently. Currently, a great race to discover new technologies and techniques to synthesize new antibodies and significantly increase the production of murine mAbs. New technologies such as laser and LED are innovations and widespread in modern life, so much so that its use has proliferated worldwide, primarily in the medical field. Recent studies show a series of results from the influence of the LED light in biological tissues such as: increasing the rate of cell proliferation, increased production rate of fibroblasts, increasing the rate of synthesis of RNA and DNA synthesis of ATP, etc. To assess the contribution of the LED in the culture of Myeloma NS1murino compared to the standard procedure. - NS1 cells were provided and followed the criteria of culture medium of the Laboratory of Cellular Engineering Center of Botucatu (POPs). The same amount of cells was grown in bottles of 25 cm2 polystyrene Tissue Culture Treated, specifically marked and kept in special medium RPMI 1640 Gibco BRL supplemented with fetal bovine serum 10%, essential amino acids and non-essential, glucose, insulin and antibiotics. It was used in LEDs Cromatek wavelength of 630nm, 475nm and 530nm. The groups were... (Complete abstract click electronic access below)

Since its discovery, radioactivity has brought numerous benefits to human societies. It has many applications in medicine, serving as a tool for non-invasive methods for diagnosis and therapies against diseases such as cancer. It also applies to technologies for energy in nuclear power plants with relatively low impacts on terms of perfect security. All applications, however, have risks, requiring maximum caution to drive processes and operations involving radioactive elements because, once released into the environment, they have extremely harmful effects on organisms affected. This paper presents fundamental concepts and principles of nuclear physics in order to understand the effects of radioactive elements released into the environment, culminating on the issue of radioactive contamination. Literature review allowed us to understand the radioactive contamination problem on living beings. Three major nuclear accidents have happened in the last thirty years, two of them in consecutive years. The nuclear accident at Chernobyl, Ukraine, in 1986, polluted large areas, condemning hundreds of thousands of people to live with consequences of the accident and effects of radiation, killing thousands of people throughout the years. In 1987, a major radiological accident occurred in Goiania (GO) when a source of radioactive cesium was violated, leading to the death of those who had direct or indirect contact with cesium. The most recent accident, in March, 2011, was located at the nuclear power plant in Fukushima Prefecture, Japan, after an earthquake and tsunami hit the region. There is no extensive and accurate knowledge about the consequences of the contamination entailed in that accident, although it is possible to verify signals on a global scale. An analysis of reports of contamination of large areas generated by nuclear plants with release of hazardous wastes suggests it is necessary to rethink the energy matrix of the various countries...
