Ensaios biológicos para avaliação de segurança de produtos cosméticos

Despite efforts to the contrary, some cosmetic products can cause undesirable side effects in the users. These may often be due to individual factors or inappropriate use of the product. Thus, biological assays to assess the safety of a new cosmetic must precede its being placed on the market. Historically, these tests have always been carried out in vivo, in animals, since such tests can be used to evaluate many of the potential risks, such as irritation, allergy or systemic effects; but, recently, some research centers have been adopting in vitro alternatives, in order to replace the animal tests. This review emphasizes the need to employ biological assays to test the safety of cosmetic products, and reviews the main in vivo and in vitro tests used, focusing on the need to develop and use alternatives to the in vivo assays of product safety, so as to offer the consumers the maximum safety with the least possible risk, while ensuring the best conditions of use of the product.

Fatores antinutricionais e coeficientes de digestibilidade aparente da proteína de produtos de soja para o pacu (Piaractus mesopotamicus)

This study aimed to determine the activities of trypsin inhibitors, hemagglutinant and tannin levels in soybean meal and in raw and processed soy, as well evaluate the protein apparent digestibility coefficient for pacu juveniles. The apparent coefficients of raw, extruded, toasted and milled soy were determined using chromium oxide (0.5%) as marker. A reference diet was created with 26% crude protein and 4,352 kcal kg-1, with each feed containing 30% of the test diet. Feces were collected by abdominal pressure. All analyzed products presented anti-nutritional factors, but the lowest trypsin inhibitor activity was observed in soybean meal. Soy that received thermal treatment presented better digestibility coefficients and lower hemagglutinating activity values than raw soy. No effects of trypsin and tannin inhibitor were observed on the protein digestibility coefficient, but a negative relationship was observed between hemagglutinin levels and protein digestibility coefficient. The use of soybean meal and extruded or toasted soy is recommended for pacu feeding.

Produtos naturais no comportamento defensivo de Apis mellifera L.

The goal was to investigate the influence of natural products such as lemongrass (Cymbopogon citratus), dried avocado leaves (Persea americana), coffee husk (Coffea arabica) and castor bean (Ricinus communis) in the defense of Apis mellifera, as well the effect of these products on the population development of the beehive. Defensive behavior was evaluated by time of first sting (TFS) and number of stingers (NS), and population development, by open brood area and operculated brood. It was observed that the treatment with smoke + seven castor beans presented significant increase in the TFS, for treatment without and with smoke. Regarding NS, it was verified that the treatments with smoke + seven castor bean and smoke + 20% coffee husk were different from the treatment without and with smoke. The other treatments did not differ significantly with respect to the use of smoke or its absence. The application of coffee husk and castor bean did not interfere in the development of the population, suggesting that these compounds were not toxic. It can be concluded that the use of castor bean and coffee husk in smoke may represent an important tool for the reduction of defensiveness, without promoting toxicity for A. mellifera.

Efeito de produtos químicos sobre a mancha bacteriana (xanthomonas perforans) e na ativação de proteínas relacionadas à patogênese em tomateiro

The present study aims to evaluate the effect of fungicides and antibiotics to control bacterial spot (Xanthomonas perforans) in tomato, and the activation of pathogenesis-related proteins. Hybrid tomato AP 529 was used to assess the severity of disease. The treatments consisted of spraying with acibenzolar-S-methyl, fluazinam, pyraclostrobin, pyraclostrobin + methiran, copper oxychloride, copper oxychloride and mancozeb + oxytetracycline, and inoculated and non-inoculated controls. After three days of treatment, all plants were inoculated with X. perforans (10 6 CFU / mL). Leaf discs were collected for assessment of peroxidase, polyphenol oxidase, β-1,3 glucanase, phenylalanine ammonia lyase and protease. The area under the disease progress curve (AUDPC) was calculated with the data of severity. All treatments had reduced AUDPC compared to the inoculated control. Fungicides acibenzolar-S-methyl, pyraclostrobin, and pyraclostrobin + methiran had more satisfactory results in reducing the severity of bacterial spot on tomato. The products based on pyraclostrobin together with acibenzolar-S-methyl induced enzymatic activities of peroxidase, polyphenoloxidase and β-1,3 glucanase, indicating that these products may be related to the induction of resistance to bacterial spot on tomato plants.

Fungos endofíticos: Uma fonte inexplorada e sustentável de novos e bioativos produtos naturais

Endophytic fungi are a rich source of new and biologically active natural products. They colonize a relatively unexplored ecological habitat and their secondary metabolism is particularly active, presumably due to metabolic interactions with their hosts. In the course of our continuing investigations for new and bioactive compounds from endophytic fungi from brazilian flora Alibertia macrophylla, Caseria sylvestris, Ocotea corymbosa, Cassia spectabilis, Piper aduncum, Cryptocaria mandioccana, Xylopia aromatica and Palicourea marcgravii were investigated. Forty two natural products were isolated and their structures were established on the basis of comprehensive spectral analysis, mainly using 1D and 2D NMR experiments. The compounds were tested in their antifungal, antioxidant, anticholinesterasic and anticancer activities.

Inovação no desenvolvimento de produtos em cluster industrial: Práticas do setor moveleiro de votuporanga

It is notorious that the cluster formation is a possibility for micro, small and medium companies to become more competitive. This research therefore aims to analyze leading practices for product innovation in companies belonging to the cluster of Votuporanga, which is the largest furniture industry in production and exporting of São Paulo state. Therefore, we conducted a survey research and data were collected from 61 furniture companies in the region of Votuporanga-SP. Among the main results it is observed that the incremental innovation of products is a central characteristic between the companies in cluster and there is little collaboration for the joint development of products from these companies with external agents such as research institutes, universities and even suppliers.
