Allosteric process of human glucokinase conducive to fight against diabetes

More than 200 million people worldwide have diabetes. In China alone, about 60 million people are suffering from the disease.Fortunately, scientists are pushing back its boundaries. For instance, a recent study by CAS researchers may shed new light on the treatment of the disease by making cutting-edge progress on studies of the allosteric process of human glucokinase, which has been published by the latest issue of the Proceedings of National Academy of Sciences.     

反学术腐败,不要反错方向

北大“王铭铭事件”爆发后,引起学术界很大震动,学者们纷纷批评学术界的不诚实行为;继续开展学术界的道德纯洁活动很有必要,我也认为剽窃行为是学术界出现腐败的表现之一,北大对“王铭铭事件”的处理也是恰到好处的,起到了“惩前毖后,治病救人”的作用。北大不愧是北大。但是“王铭铭事件”经过某些媒体炒作,被作为“学术腐败”的主要甚至是唯一内容,一些科技界的官员纷纷发表讲话、文章,更是把反“学术腐败”、科技界腐败的矛头对准科学家;硬是把科技界反腐败的水搅浑了。 学术界有腐败,科技界有腐败,这个腐败主要还出在科技界

Impacts of COVID-19: A research agenda to support people in their fight

Grounded in the vast changes to work life (jobs) and home life that people are facing due to the COVID-19 pandemic (hereinafter COVID), this article presents five research directions related to COVID’s impacts on jobs—i.e., job loss, job changes, job outcomes, coping, and support—and five research directions related to COVID’s impact on home life—i.e., home life changes, children, life-related outcomes, social life, and support. In addition to this, I discuss overarching possible research directions and considerations for researchers, editors, and reviewers, as we continue our scientific journey to support people through this pandemic and beyond. I organize these directions and considerations into two sets of five each: focal groups that should be studied—i.e., underprivileged populations, different countries and cultural contexts, women (vs. men), workers in healthcare (frontline workers), elderly and at-risk—and five general issues and special considerations—i.e., role of technology as the oxygen, pre- vs. mid- vs. post-COVID studies, constraints on data collection/research due to COVID, evolution of COVID, and focus on contextualization (generalizability is irrelevant).     

Going beyond fact-checking to fight health misinformation: A multi-level analysis of the Twitter response to health news stories

Health misinformation has become an unfortunate truism of social media platforms, where lies could spread faster than truth. Despite considerable work devoted to suppressing fake news, health misinformation, including low-quality health news, persists and even increases in recent years. One promising approach to fighting bad information is studying the temporal and sentiment effects of health news stories and how they are discussed and disseminated on social media platforms like Twitter. As part of the effort of searching for innovative ways to fight health misinformation, this study analyzes a dataset of more than 1600 objectively and independently reviewed health news stories published over a 10-year span and nearly 50,000 Twitter posts responding to them. Specifically, it examines the source credibility of health news circulated on Twitter and the temporal, sentiment features of the tweets containing or responding to the health news reports. The results show that health news stories that are rated low by experts are discussed more, persist longer, and produce stronger sentiments than highly rated ones in the tweetosphere. However, the highly rated stories retained a fresh interest in the form of new tweets for a longer period. An in-depth understanding of the characteristics of health news distribution and discussion is the first step toward mitigating the surge of health misinformation. The findings provide insights into understanding the mechanism of health information dissemination on social media and practical implications to fight and mitigate health misinformation on digital media platforms.

乳酸处理麦麸对蛋鸡生产性能影响研究

将 1 44只黄金褐 2 5周龄蛋鸡随机分为 4组 ,对照组日粮中添加未经乳酸处理的麦麸 ,试验1组、试验 2组和试验 3组日粮中分别添加乳酸处理麦麸 3%、7%和 1 0 %。饲养试验结果表明 :各试验组和对照组在采食量和蛋重方面差异不显著 ( P>0 .0 5 )。试验 1组和试验 2组在破蛋率、死淘率、料蛋比方面都比对照组低 ,但产蛋率差异不显著 ( P>0 .0 5 ) ;试验 3组与对照组、试验 1组、2组在料蛋比、破蛋率和产蛋率上存在着显著差异 ( P<0 .0 5 )。代谢试验结果表明 :粗蛋白质和钙磷代谢率随着乳酸处理麦麸在日粮中的添加比例增高 ,呈明显下降趋势 ;而粗脂肪、粗纤维代谢率呈上升趋势。

Lysosomal enzyme release from normal human polymorphonuclear leukocytes in response to particulate stimuli

The microbicidal capacity of polymorphonuclear (PMN) leukocytes of normal human subjects was evaluated by estimating the release of lysosomal enzymes from normal cells and cells rendered incapable of ingesting particles by treatment with cytochalasin B, on exposure to a particulate stimulus-serum treated zymosan (STZ). The release of lysosomal enzymes namely beta-glucuronidase, lysozyme, acid phosphatase, alkaline phosphatase was found to be 16.28%, 27.84%, 20.54%, 15.40% respectively. The cells rendered incapable of ingesting particles showed enhanced response. The percentage release of beta-glucuronidase, lysozyme, acid and alkaline phosphatase was increased to 20.58%, 37.95%, 25.87% and 33.04% respectively. This type of response in cytochalasin B treated PMN leukocytes is due to the conversion of these cells into “secretory cells”, which release lysosomal enzymes outside the cell, by the process of reverse endocytosis.
