INFRARED LIGHT AND BIOMEDICAL TELEMETERING IN EUROPE
International Telemetering Conference Proceedings / October 22-25, 1984 / Riviera Hotel, Las Vegas, NevadaThe applicability of telemetering devices in patient care and biomedical research is extended by the introduction of infrared (IR) light communication techniques. Research in this field demonstrated a particularly interesting potential for a multichannel/multipatient monitoring system comprising stimulation, remote control of physiological functions or drug delivery, and patient location. Compared to radiofrequency links IR-telemetry features distinct advantages, i.e. a wide transmission bandwidth which is not restricted by any government regulations, no interference with identical systems in adjacent rooms, no connector or antenna problems, and a cost-saving simple generation and detection of IRcarriers. Examples of recent laboratory and industrial developments are described.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.

Atividade antimicrobiana de Schinus terebenthifolius Raddi Antimicrobial activity of Schinus terebenthifolius Raddi
Objetivou-se com este trabalho analisar a atividade antimicrobiana de extratos aquoso e alcoólico obtidos de frutos da Schinus terebenthifolius ou aroeira-vermelha, diretamente ligados à quantidade de compostos fenólicos existentes nesses extratos. Pelos testes, verificou-se que o extrato alcoólico apresentou efeito inibitório sobre o crescimento de Staphylococcus aureus e Bacillus cereus, já o extrato aquoso não apresentou efeito inibitório sobre os crescimento dos microrganismos testados. O extrato alcoólico mostrou-se com quantidade significativa da flavona apigenina, além de ácido elágico, ao passo que no extrato aquoso foi observada a presença da flavanona naringina.<br>This research analyzed the antimicrobial activity of aqueous and alcoholic extracts obtained from Schinus terebenthifolius fruits or aroeira-vermelha, directly linked to the amount of phenolics compouds existent in these extracts. The tests showed that the alcoholic extract presented an inibitory effect to the growth of Staphylococcus aureus and Bacillus cereus, and the aqueous extract didn't present inibitory effect to the growth of the tested microorganisms. The alcoholic extract was shown with a significant amount of the flavone apigenin, besides ellagic acid and siringic acid, while in the aqueous extract was observed the flavanone naringine
