This work explored possibilities of biodegradable magnesium alloy Mg-3Y preparation by two modern powder metallurgy tec.niques–spark plasma sintering(SPS)and selective laser melting(SlM).The powder material was c.nsolidated by both methods utilising optimised parameters,which led to very low porosity(∼0.3%)in the SlM material and unmeasurably low porosity in the SPS *** main aim of the study was the thorough microstructure characterisation and interrelation between the microstructure and the functional properties,such as mechanical strength,deformability,and corrosion *** materials showed comparable strength of∼110 MPa in tension and compression and relatively good deformability of∼9%and∼21%for the SlM and SPS materials,*** corrosion resistance of the SPS material in 0.1 M nacl solution was superior to the SlM one and comparable to the c.nventional extruded *** digital image correlation during loading and the cross-section analysis of the corrosion layers revealed that the residual porosity and large strained grains have the dominant negative effect on the functional properties of the SlM *** the other hand,one of the primary outcomes of this study is that the SPS c.nsolidation method is very effective in the preparation of the W3 biodegradable alloy,resulting in material with c.nvenient mechanical and degradation properties that might find practical applications.

Effects of metoclopramide on gastric motility measured by short-term bio-impedance

引用

World Journal of Gastroenterology 2009年第38期15卷 4763-4769页

作者： María-Raquel.huerta-Franco Miguel Vargas-luna Kathleen M capaccione Etna Yaez-Roldán Ulises Hernández-ledezma Ismael Morales-Mata Teodoro córdova-Fraga Department of Applied Science and labor Research DCS-Campus LeónUniversity of Guanajuato Department of Physical Engineering DCI-Campus LeónUniversity of Guanajuato Robert Wood Johnson Medical School The University of Medicine and Dentistry of New Jersey

AIM:To analyze the accuracy of short-term bio-impedance as a means of measuring gastric ***: We evaluated differences in the short-term electrical bio-impedance signal from the gastric region in the following c.nditions: (1) fasting state, (2) after the administration of metoclopramide (a drug that induces an increase in gastric motility) and (3) after food ingestion in 23 healthy volunteers. We record-ed the real component of the electrical impedance signal from the gastric region for 1000 s. We performed a Fast Fourier Transform (FFT) on this data and then compared the signal among the fasting, medicated, and postprandial c.nditions using the median of the area under the curve, the relative area under the curve and the main peak ***: The median of the area under the curve of the frequency range in the region between 2-8 cycles per minute (cpm) decreased from 4.7 cpm in the fasting c.ndition to 4.0 cpm in the medicated state (t=3.32, P=0.004). This c.ncurred with the decrease seen in the relative area under the FFT curve in the region from 4 to 8 cpm from 38.3% to 26.6% (t=2.81, P=0.012) and the increase in area in the region from 2 to 4 cpm from 22.4% to 27.7%, respectively (t=-2.5, P=0.022). Finally the main peak position also decreased in the region from 2 to 8 cpm. Main peak activity in the fasting state was 4.72 cpm and declined to 3.45 cpm in the medicated state (t=2.47, P=0.025). There was a decrease from the fasting state to the postprandial state at 3.02 cpm (t=4.0, P=0.0013). c.nclUSIOn: Short-term electrical bio-impedance c.n assess gastric motility changes in individuals experienc.ng gastric stress by analyzing the area medians and relative areas under the FFT curve.
