Avaliação da produção de citocinas pelos macrófagos J774. G8 após o tratamento com bioterápicos / Evaluation of cytokine production by J774. G8 macrophages after treatment with biotherapics

Strains of macrophages, such as murine J774.G8 macrophages, are susceptible to influenza A infection [1]. One of the responses to viral infection involves the production of various types of immunostimulatory cytokines by infected cells [2].In all cases, there were no significant differences compared to control groups. However, the production of TNF-? detected in macrophages treated by intact and inactivated biotherapics presented a tendency to increase after infection. In fact, similar results were previously detected in other experiments conducted only with the intact biotherapic [3]. The release of the cytokine MCP1 in all experimental situations presented a tendency to decrease after the viral infection when compared to untreated macrophages. No statistically significant difference was detected in the production of IL 12 and IL 10. These experiments will be repeated to confirm the data obtained.(AU)

Effects of electrically transferred molecular information on the germination of garden cress / Efeitos de informação molecular transferida eletricamente sobre a germinação do agrião

We followed a hypothesis that biologically relevant information from various substances can be non-chemically transferred to organisms through a combination of a high voltage electric field that can stably imprint information into water or a water solution. A special device was constructed, and a thoroughly tested biological sensor system (i.e. cress seedlings exposed to a defined heat stress), was used. The results demonstrate a clear evidence of biological effects of electrically imprinted information of biologically active substances into water solution, however not necessarily with an obvious connection to the effects of the original (donor) substance. The growth reaction of cress seedlings was either stimulatory or inhibitory, depending on the time of the application.(AU)

Seguimos a hipótese de que informação biologicamente relevante de várias substâncias pode ser transferida de maneira não química a organismos, através da combinação de um campo elétrico de alta intensidade, que pode imprimir estavelmente informação na água ou sistemas aquosos. Foi construído um aparelho especial e foi utilizado um sistema sensor especial, amplamente provado (plantas de agrião expostas a estresse térmico definido). Os resultados demonstram evidência dos efeitos de informação eletricamente impressa de substâncias biologicamente ativas em soluções aquosas. No entanto, estes efeitos não estão necessariamente ligados aos próprios da substância original (doadora). A reação de crescimento das plantas de agrião foi ora estimulatória ou inibidora, dependendo do momento da aplicação.(AU)
