1Reforestation Programs in Southwest China:Reported Success,Observed Failure, and the Reasons Why显示文摘Ever since the disastrous floods of 1998, the Chinese government has used the Natural Forest Protection and Sloping Land Conversion Programs to promote afforestation and reforestation as means to reduce runoff, control erosion, and stabilize local livelihoods. These two ambitious programs have been reported as large-scale successes, contributing to an overall increase in China’s forest cover and to the stated goals of environmental stabilization. A small-scale field study at the project level of the implementation of these two programs in Baiwu Township, Yanyuan County, Sichuan, casts doubt upon the accuracy and reliability of these claims of success; ground observations revealed utter failure in some sites and only marginal success in others. Reasons for this discrepancy are posited as involving ecological, economic, and bureaucratic factors. Further research is suggested to determine whether these discrepancies are merely local aberrations or represent larger-scale failures in reforestation programs.Christine Jane Trac Stevan Harrell Thomas M.

2Acute effects of rotavirus and malnutrition on intestinal barrier function in neonatal piglets显示文摘AIM: To investigate the effect of protein-energy malnutrition on intestinal barrier function during rotavirus enteritis in a piglet model.METHODS: Newborn piglets were allotted at day 4 of age to the following treatments:(1) full-strength formula(FSF)/noninfected;(2) FSF/rotavirus infected;(3) half-strength formula(HSF)/noninfected;or(4) HSF/rotavirus infected.After one day of adjustment to the feeding rates,pigs were infected with rotavirus and acute effects on growth and diarrhea were monitored for 3 d and jejunal samples were collected for Ussingchamber analyses.RESULTS: Piglets that were malnourished or infected had lower body weights on days 2 and 3 post-infection(P < 0.05).Three days post-infection,marked diarrhea and weight loss were accompanied by sharp reductions in villus height(59%) and lactase activity(91%) and increased crypt depth(21%) in infected compared with non-infected pigs(P < 0.05).Malnutrition also increased crypt depth(21%) compared to full-fed piglets.Villus:crypt ratio was reduced(67%) with viral infection.There was a trend for reduction in transepithelial electrical resistance with rotavirus infection and malnutrition(P = 0.1).3H-mannitol flux was significantly increased(50%;P < 0.001) in rotavirus-infected piglets compared to non-infected piglets,but there was no effect of nutritional status.Furthermore,rotavirus infection reduced localization of the tight junction protein,occludin,in the cell membrane and increased localization in the cytosol.CONCLUSION: Overall,malnutrition had no additive effects to rotavirus infection on intestinal barrier function at day 3 post-infection in a neonatal piglet model.Sheila K Jacobi Adam J Moeser Anthony T Blikslager J Marc Rhoads Benjamin A Corl Robert J Harrell Jack Odle 2013World Journal of Gastroenterology2013,19,31:4
3Takotsubo cardiomyopathy:A comprehensive review显示文摘Takotsubo cardiomyopathy(TCM),also known as stress cardiomyopathy,occurs in the setting of catecholamine surge from an acute stressor.This cardiomyopathy mimics acute myocardial infarction in the absence of coronary disease.The classic feature of TCM is regional wall motion abnormalities with characteristic ballooning of the left ventricle.The etiology of the stressor is often physical or emotional stress,however iatrogenic causes of TCM have been reported in the literature.In our review,we discuss medications,primarily the exogenous administration of catecholamines,and a wide array of procedures with subsequent development of iatrogenic cardiomyopathy.TCM is unique in that it is transient and has favorable outcomes in most individuals.Classically,beta-blockers and ACE-inhibitors have been prescribed in individuals with cardiomyopathy;however,unique to TCM,no specific treatment is required other than temporary supportive measures as this process is transient.Additionally,no improvement in mortality or recurrence have been reported in patients on these drugs.The aim of this review is to elucidate on the iatrogenic causes of TCM,allowing for prompt recognition and management by clinicians.Walker Barmore Himax Patel Sean Harrell Daniel Garcia Joe B Calkins Jr 2022World Journal of Cardiology2022,14,6:2
