1Alcohol consumption on pancreatic diseases显示文摘Although the association between alcohol and pancreatic diseases has been recognized for a long time,the impact of alcohol consumption on pancreatitis and pancreatic cancer(PC)remains poorly defined.Nowadays there is not consensus about the epidemiology and the beverage type,dose and duration of alcohol consumption causing these diseases.The objective of this study was to review the epidemiology described in the literature for pancreatic diseases as a consequence of alcoholic behavior trying to understand the association between dose,type and frequency of alcohol consumption and risk of pancreatitis and PC.The majority of the studies conclude that high alcohol intake was associated with a higher risk of pancreatitis(around 2.5%-3% between heavy drinkers and 1.3%between non drinkers).About 70%of pancreatitis are due to chronic heavy alcohol consumption.Although this incidence rate differs between countries,it is clear that the risk of developing pancreatitis increases with increasing doses of alcohol and the average of alcohol consumption vary since 80 to 150 g/d for 10-15 years.With regard to PC, the role of alcohol consumption remains less clear,and low to moderate alcohol consumption do not appear to be associated with PC risk,and only chronic heavy drinking increase the risk compared with lightly drinkers.In a population of 10%-15%of heavy drinkers, 2%-5%of all PC cases could be attributed to alcohol consumption.However,as only a minority(less than 10%for pancreatitis and 5%for PC)of heavily drinkers develops these pancreatic diseases,there are other predisposing factors besides alcohol involved.Genetic variability and environmental exposures such as smoking and diet modify the risk and should be considered for further investigations.Marta Herreros-Villanueva Elizabeth Hijona Jesus Maria Baales Angel Cosme Luis Bujanda 2013World Journal of Gastroenterology2013,19,5:3
2Sharkskin-Inspired Magnetoactive Reconfigurable Acoustic Metamaterials显示文摘Most of the existing acoustic metamaterials rely on architected structures with fixed configurations,and thus,their properties cannot be modulated once the structures are fabricated.Emerging active acoustic metamaterials highlight a promising opportunity to on-demand switch property states;however,they typically require tethered loads,such as mechanical compression or pneumatic actuation.Using untethered physical stimuli to actively switch property states of acoustic metamaterials remains largely unexplored.Here,inspired by the sharkskin denticles,we present a class of active acoustic metamaterials whose configurations can be on-demand switched via untethered magnetic fields,thus enabling active switching of acoustic transmission,wave guiding,logic operation,and reciprocity.The key mechanism relies on magnetically deformable Mie resonator pillar(MRP)arrays that can be tuned between vertical and bent states corresponding to the acoustic forbidding and conducting,respectively.The MRPs are made of a magnetoactive elastomer and feature wavy air channels to enable an artificial Mie resonance within a designed frequency regime.The Mie resonance induces an acoustic bandgap,which is closed when pillars are selectively bent by a sufficiently large magnetic field.These magnetoactive MRPs are further harnessed to design stimuli-controlled reconfigurable acoustic switches,logic gates,and diodes.Capable of creating the first generation of untethered-stimuli-induced active acoustic metadevices,the present paradigm may find broad engineering applications,ranging from noise control and audio modulation to sonic camouflage.Kyung Hoon Lee Kunhao Yu Hasan Al Ba’ba’a An Xin Zhangzhengrong Feng Qiming Wang 2020Research2020,,1:2
