Hyperactive androgen receptor （AR） activity remains a key determinant of the onset and progression of prostate cancer and resistance to current therapies. The mechanisms governing castrate resistant prostate cancer are poorly understood, but defining these molecular events is essential in order to impact deaths from prostate cancer.

Assessment of soil health requires complexevaluation of properties and functions responsible for abroad range of ecosystem services. Numerous soil qualityindices (SQI) have been suggested for the evaluation ofspecific groups of soil functions, but comparison of variousSQI is impossible because they are based on a combinationof specific soil properties. To avoid this problem, wesuggest an SQI-area approach based on the comparison ofthe areas on a radar diagram of a combination of chemical,biological and physical properties. The new approach isindependent of the SQI principle and allows rapid andsimple comparison of parameter groups and soils. Anotherapproach analyzing the resistance and sensitivity ofproperties to degradation is suggested for a detailedevaluation of soil health. The resistance and sensitivityof soil properties are determined through comparison withthe decrease of soil organic carbon (SOC) as a universalparameter responsible for many functions. The SQI-areaand resistance/sensitivity approaches were tested based on quences after the ab and on ment of agricultural soils. Both the SQI-area and the resistance/sensitivity approaches areuseful for basic and applied research, and for decisionmakersto evaluate land-use practices and measure thedegree of soil degradation.

亚微米级颗粒是化学工业尾气排放物的重要组成,其脱除效率是影响排放指标进一步提高的关键。基于颗粒捕获机理,建立了气液交叉流系统脱除效率的理论模型,并对该系统脱除亚微米级颗粒的特性进行了理论分析和实验研究。实验结果表明,低气速、高液柱群比表面积、高气液相温差有利于提升系统的脱除效率。粒径0.05~0.6μm,脱除效率随粒径的增大呈现先降低后增加的趋势,与理论值趋势一致,表明系统中同时存在惯性碰撞、拦截、布朗运动等三种脱除机理。相对于理论值,实验脱除率整体偏大,表明颗粒在高湿环境中易凝并,有助于颗粒在碰撞和拦截作用下的脱除。由实验数据外推,研究条件下,液柱单元排数为1300时,亚微米级颗粒质量脱除效率预计可达90%。

BACKGROUND: The purpose of this study was to use point-of-care ultrasound(POCUS) to investigate the relationship between tobacco smoke exposure and the characteristics of the common carotid artery(CCA). The effect of both primary and secondary smoking on CCA properties was ***: We performed a prospective cross-sectional study across 20 primary care clinics in Bandung, West Java, Indonesia in July 2016. Point of care ultrasound was performed on a convenience sample of Indonesian patients presenting to clinic. The CCA wall stiffness and carotid intima-media thickness(CIMT) were measured during diastole and systole. These measurements were correlated with smoke exposure and cardiovascular ***: We enrolled 663 patients in the study, with 426 patients enrolled in the smoking category and 237 patients enrolled in the second-hand smoke category. There was an overall positive correlation with the measured lifestyle factors and the ultrasound-measured variables in the group of individuals who smoked. For all variables, age seemed to contribute the most out of all of the lifestyle factors for the positive changes in CIMT and CCA wall ***: Our data yielded correlations between CCA properties and cardiovascular risk, as well as between CIMT and arterial stiffness. We were also able to demonstrate an increase in thickness of the CIMT in patients who have been exposed by tobacco through the use of ultrasound. Further large scale studies comparing patients with multiple cardiac risk factors need to be performed to confi rm the utility of ultrasound fi ndings of cardiovascular disease and stroke.
