Objective:To evaluate the effect of ureteral access sheath(UAS)use and calibration change on stone-free rate and complications of retrograde intrarenal surgery(RIRS).Methods:Data from 568 patients undergoing RIRS for kidney or upper ureteral stones were retrospectively ***,patients were compared after 1:1 propensity score matching,according to UAS usage during RIRS(UAS used[+]87 and UAS non-used[−]87 patients).Then all UAS+patients(n=481)were subdivided according to UAS calibration:9.5-11.5 Fr,10-12 Fr,11-13 Fr,and 13-15 *** outcomes of the study were the success and complications of ***:Stone-free rate of UAS+patients(86.2%)was significantly higher than UAS−patients(70.1%)after propensity score matching(p=0.01).Stone-free rate increased with higher caliber UAS(9.5-11.5 Fr:66.7%;10-12 Fr:87.0%;11-13 Fr:90.6%;13-15 Fr:100%;p<0.001).Postoperative complications of UAS+patients(11.5%)were significantly lower than UAS−patients(27.6%)(p=0.01).Complications(8.7%)with 9.5-11.5 Fr UAS was lower than thicker UAS(17.2%)but was not statistically significant(p=0.09).UAS usage was an independent factor predicting stone-free status or peri-and post-operative complications(odds ratio[OR]3.654,95%confidence interval[CI]1.314-10.162;OR 4.443,95%CI 1.350-14.552;OR 4.107,95%CI 1.366-12.344,respectively).Conclusion:Use of UAS in RIRS may increase stone-free rates,which also increase with higher caliber *** usage may reduce complications;however,complications seemingly increase with higher UAS calibration.

Connexin 43 (CX43) is one of the major components of gap junctions, the structures responsible for the intercellular communication and transmission of the electrical impulse in the left ventricle. There is limited information on the histological changes of CX43 with age and their effect on electrophysiology, especially in humans. Here, we analyzed left ventricular biopsies from living donors starting at midlife to characterize age-related CX43 remodeling. We assessed its quantity, degree of lateralization, and spatial heterogeneity together with fibrotic deposition. We observed no significant age-related remodeling of CX43. Only spatial heterogeneity increased slightly with age, and this increase was better explained by biological age than by chronological age. Importantly, we found that CX43 features varied considerably among individuals in our population with no relevant relationship to age or fibrosis content, in contrast to animal species. We used our experimental results to feed computational models of human ventricular electrophysiology and to assess the effects of interindividual differences in specific features of CX43 and fibrosis on conduction velocity, action potential duration, and arrhythmogenicity. We found that larger amounts of fibrosis were associated with the highest arrhythmic risk, with this risk being increased when fibrosis deposition was combined with a reduction in CX43 amount and/or with an increase in CX43 spatial heterogeneity. These mechanisms underlying high arrhythmic risk in some individuals were not associated with age in our study population. In conclusion, our data rule out CX43 remodeling as an age-related arrhythmic substrate in the population beyond midlife, but highlight its potential as a proarrhythmic factor at the individual level, especially when combined with increased fibrosis.

作者： KristianTφnder Norwegian University of Science and Technology

The improvement of lubrication of piston ring-cyinder liner is always in demand, andsurface roughness behaviour plays a very important role. The present paper will explore this be-haviour and investigate how the inlet roughness of ring influences the lubrication of pistonring-cylinder. The quantitative results of this combination of surface roughness on friction force, oilfilm thickness and frictional power loss are given and discussed.

Seed,germination,and seed-reserve traits differ along an altitudinal gradient

Turkish red pine(P inus brutia Ten.), an important pine species for afforestation studies, grows at a wide range of altitudes in the eastern Mediterranean area. Seeds from low(0–400 m a.s.l.), mid(400–800 m) and high(800–1000 m) altitudinal gradients were collected to assess the effects of these gradients on morphological traits(seed length, seed width, 100-seed weight), germination variables(germination percentage and mean germination time), and 10biochemical variables related to seed reserves. Relationships among these variables were examined with a correlation analysis. Seeds from low and high altitudes had significantly higher 100-seed weight, higher percentage germination but longer germination times and higher total oil and reducing sugars contents. Seeds from mid altitudes had higher carotenoid and soluble phenolics contents. Among the examined biochemical variables, only flavonoid content did not differ among the altitude gradients. The main fatty acids in seeds samples(linoleic, oleic, palmitic and stearic acids) were also influenced by the altitude gradients. Oil and total reducing sugars contents were positively correlated with germination percentage, and carotenoid content was negatively correlated with germination percentage. Our results confirmed that seed and germination variables, including the reserve composition varied significantly among the altitudinal gradients.
