Intermediate conductance, Ca^2＋-activated K^＋ channels： a novel target for chronic renal diseases

Frontiers in Biology 2015年第1期10卷 52-60页

作者： Claudia A. bertuccio Daniel C. DEVOR Department of Cell Biology School of Medicine University of Pittsburgh Pittsburgh PA 15261 USA

Renal failure is a medical condition in which the kidneys are not working properly. There are two types of kidney failure： 1） acute kidney failure, which is sudden and often reversible with adequate treatment; and 2） chronic renal failure, which develops slowly and often is not reversible. The last stage of chronic renal failure is fatal without dialysis or kidney transplant. The treatment for chronic renal failure is focusing on slowing the progression of kidney damage. Several reports have described a promising approach to slow the loss of renal function through inhibition of the basolateral membrane, Ca^2＋-activated K^＋（KCa3.1） channel with a selective and nontoxic blocker TRAM-34. This review summarizes pathophysiological studies that describe the role of KCa3.1 in kidney diseases.

Aim:We aimed to analyze temporal trends in mortality from intrahepatic(ICC)and extrahepatic(ECC)cholangiocarcinoma in selected countries worldwide.Methods:Official death certification data for ICC and ECC and populations estimates for 29 countries worldwide(17 from Europe,8 from the Americas,and 4 from Australasia)and for Hong Kong Special Administrative Region of the People’s Republic of China(SAR),from 1995 to 2018,were extracted from the World Health Organization and the Pan American Health Organization databases.Age-standardized mortality rates were computed.A joinpoint regression analysis was performed.Results:In both sexes,ICC mortality rates increased in most countries considered,including the USA,the UK,and Australia;in some countries,including Italy and France,the increasing trends leveled off over the most recent years.In men,around 2016,the highest rates(1.7-2.3/100,000)were observed in Hong Kong SAR,Portugal,France,Spain,Australia,Austria,the UK,and Canada;Latin American countries and some eastern European countries had the lowest rates(0.2-0.8/100,000).A similar pattern was observed in women,but with lower rates(from 1.7/100,000 in Hong Kong SAR to 0.14/100,000 in Argentina).ECC mortality declined in most European and Australasian countries,but it tended to increase in Americas.In both sexes,rates were below 1/100,000 around 2016,with the only exceptions being Japan(2.6/100,000 men and 1.2/100,000 women)and Hungary(1.5/100,000 men and 1.1/100,000 women).Conclusion:ICC mortality increased in most areas of the world,likely due to increased prevalence of risk factors and improved cancer recognition and classification.ECC mortality fell in most countries,largely due to the widespread use of cholecystectomy.

In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.
