AIM: To evaluate changes in neurotransmission induced by a psychoactive beverage ayahuasca in the hippocampus and amygdala of naive rats. METHODS: The level of monoamines, their main metabolites and amino acid neurotransmitters concentrations were quantified using high performance liquid chromatography(HPLC). Four groups of rats were employed: saline-treated and rats receiving 250, 500 and 800 mg/kg of ayahuasca infusion(gavage). Animals were killed 40 min after drug ingestion and the structures stored at-80 ℃ until HPLC assay. The data from all groups were compared using Analysis of variance and Scheffé as post test and P dala of rats that received 500 of ayahuasca. Animals that ingested 800 mg/kg of ayahuasca also showed a reduction of GLY level(0.11 ± 0.01 vs 0.29 ± 0.07, P dala after ayahuasca administration in doses: 250 mg/kg(noradrenaline: 0.16 ± 0.02 vs 0.36 ± 0.06, P data suggest increased release of inhibitory amin

Design, Development and Geometric Error Analysis of an Aerostatic Rotary Table

引用

Journal of Mechanics Engineering and Automation 2016年第3期6卷 133-147页

作者： Verilton Nunes da Silva Luiz henrique Melo Silva Nobrega Fabio de Andrade Barroso rafael Franklin Alves Silva Jobson Francisco da Silva Jose Carlos de Lima JUnior and Joaio Bosco de Aquino Silva

Rotary tables are equipments in precision machinery applied in five-axis Machine Tools and CMM （Coordinate Measuring Machines）, offering rotational （C-axis） and tilting motion （A-axis）, allowing the obtaining of several configurations for manufacturing or inspection of parts with complex geometries. The demand for high accuracy, high efficiency and fewer errors in the positioning of the part in precision machines increases every day, thus ensuring their high confidence and the use of aerostatic bearings enable constructive innovations to the equipment. In this context, this work presents the mechanical design, the development and error analysis of a prototype of an aerostatic rotary table. This study emphasizes the analysis of a prototype that uses the air as a working principle for reducing friction between moving parts, increasing the mechanical efficiency, and its influence of motion error is also discussed based on the experimental results. For the geometrical errors analysis, experimental tests were realized in laboratory using a DBB （Double Ballbar）. The tests are performed with only one axis moving, observing the behavior of the system for different feedrate at the C-axis.

Mechanical Circulatory Support in Patients with Sepsis： A Case Series

MCS （mechanical circulatory support） has shown great efficacy in treatment of respiratory mid cardiovascular diseases when conventional therapy is insufficient. The use of ECMO （extracolporeal membrane oxygenation） for the treatment of cardiogenic shock secondary to sepsis is still controversial. Studies have shown that ECMO should be considered as a valuable therapeutic option in cases of refractory cardiovascular dysfunction in severe septic patients, although more studies ale needed to consolidate its efficacy. We report the case of two patients, without previous history of cardiopathy, subjected to temporary MCS, with use of ECMO for the treatment of refractory cardiogenic shock secondary to sepsis.

Mean and Interannual Variability of Maize and Soybean in Brazil under Global Warming Conditions

Brazil is responsible for 27% of the world production of soybeans and 7% of maize. Mato Grosso and Para states in Brazil are among the largest producer. The viability to the cultivation of maize (Zea mays) and soybeans (Glycine max), for future climate scenarios (2070-2100, GHG) is evaluated based on crop modeling (DSSAT) forced by observational data and regional climate simulations (HadRM3). The results demonstrated that a substantial reduction in the yield in particular for maize may be expected for the end of the 21st century. Distinct results are found for soybeans. By applying the A2 climate changes scenario, soybean yield rises by up top 60% assuming optimum soil treatment and no water stress. However, by analyzing the inter-annual variability of crop yields for both maize and soybean, could be demonstrated larger year-to-year fluctuations under greenhouse warming conditions as compared to current conditions, leading to very low productivity by the end of the 21st century. Therefore, these Brazilian states do not appear to be economically suitable for a future cultivation of maize and soybeans. Improved adaptation measures and soil management may however partially alleviate the negative climate change effect.
