Utilização de biomateriais poliméricos associados a implantes dentários: revisão de literatura

A remodelação óssea é um processo contínuo, que possibilita a substituição de osso envelhecido e danificado por tecido novo. A reparação ao redor de implantes osseointegráveis e enxertos ósseos em situações desfavoráveis depende do estabelecimento de um adequado contato entre tecido ósseo e implante por meio da estabilidade primária. Tendo em vista a importância da estabilidade primária do implante na biomecânica e conseqüente osseointegração, a associação de biomateriais reabsorvíveis ao sítio de instalação dos implantes se torna relevante. Destes biomateriais, destaca-se o copolímero de ácido polilático/ poliglicólico (PLA/PGA), que poderia contribuir com a estabilidade temporária dos implantes.

Enxerto ósseo em odontologia: revisão de literatura

Bone is a specialized connective tissue, vascular and dynamic changes over the life of the organism. When injured, has a unique ability to regenerate and repair without the presence of scars, but in some situations due to the size of the defect, the bone tissue does not regenerate so completely, it is necessary to carry out bone grafting procedures. Considering there are various types of grafts and various donor sites. Thus, the aim of this study was to review the literature to some type of graft most commonly used in dentistry. Given the importance of bone reconstruction in oral and maxillofacial surgery, it is necessary to know the viability and influence of biomaterials, or not associated with autogenous grafts in bone repair. Even this, with many qualities, but further studies should be done to achieve each day, a synthetic material compatible with bone tissue lost in adequate amounts without requiring extra-oral surgeries that are considered to be devoted to higher morbidity.

Prevalência de acidentes com material biológico em um município do noroeste de São Paulo, Brasil, no período de 2007 a 2011

The objective of this study is to determine the prevalence of reports of accidents involving biological material which affected health professionals, especially dental health ones, in a city in the north­western region of São Paulo State, Brazil. Data collection was con­ducted through the notification of accidents with biological material from 2007 to 2011. There were 377 notifications, in which 353 (93.6%) had female professionals involved. The most reported type of exposure was the percutaneous in 359 cases (95.2%) followed by blood in 334 cases (88.6%) which is the most mentioned biological material in the reports. Only 21 (5.6%) notifications were from den­tal staff and occurred mostly with the dentist, 14 times (66.7%) and 16 times (76.2%) during clinical procedures. The prevalence of bio­logical accidents among dental teams was little in this time, which suggests the possibility of underreporting, in addition to being sub­ject to the partial fulfillment of the same.

O conhecimento biológico nos documentos curriculares nacionais do ensino médio: uma análise histórico-filosófica a partir dos estatutos da biologia

We analyzed the National Curriculum for Secondary Schools with respect to the ontological, epistemological, historical, social and conceptual biology. This study aims to bring information and thinking about the inclusion of history and philosophy of biology for secondary education and for teacher training. We performed an analysis of PCNEM, PCNEM+ and Curriculum Guidelines as a whole from established categories. The results indicate a predominance of the ontological view of mechanistic biology. Epistemologically, although acknowledged, the question of scientific method is rarely discussed. The historical approach and social scientific activity and scientific knowledge are recognized by the documents, but an instrumental view prevails. The conceptual aspects are comprehensive and take into account the theories of structural biology. A philosophical discussion on the biology is missing in the parameters, indicating the need for the inclusion of issues related to ideas of determinism, chance and teleology.

Tumor venéreo transmissível canino: expressão dos genes MDR-1, TP53 e da família Bcl-2 e suas implicações no comportamento biológico e terapêutico

Transmissible venereal tumor (TVT) is a neoplasm of round cells with plasmocytoid or lymphocytoid appearance. The tumor presents several particularities, which have been the subject of numerous studies; however there still have investigations that need to be done. For example, a progressive increase of highly aggressive tumors with varying response to chemotherapy -including resistance- has been evidenced in recent years. There is scientific interest to understand these differences, allowing predicting possible clinical outcomes in affected dogs and increasingly searching adequate and individualized therapy. This review focuses on presenting possible implications of the expression of MDR-1 (P-glycoprotein), TP53, BCL-2, and BAX genes, regarding resistance to chemotherapy and/or the biologic behavior of TVT

Potencial do controle biológico para o controle de Pseudoplusia includens (Walker, 1857) e Anticarsia gemmatalis Hubner, 1818 (Lepidoptera: Noctuidae) em soja

The soybean (Glycine max) is of great importance to national economic scenario being a major Brazilian agribusiness products. In most regions, the caterpillar-of-soy (Anticarsia gemmatalis) and caterpillar-false-Medideira (Pseudoplusia includes), act as defoliators, with the highest incidence, usually during the growing season, until the end of flowering, and thus causing a significant reduction in the production, which requires control measures. Due to market demands and the large external environmental awareness exists today, the methods of ecological management have been highlighted in modern agriculture. The use of chemical insecticides, besides being harmful to the environment and man, is, in most cases, the high cost to the farmer. The biological pest control using natural enemies can be used as an alternative control method. Thus this literature review is intended to provide the updated information about these pests and biological control as an alternative form of control, as well as one more tool in the integrated pest of soybean.
