Harmonious Corporate Governance

Changing Trends in Lower Gastrointestinal Hemorrhage: A Rise in Frequency of Ischemic Colitis

文明的和谐与共同繁荣：人类文明的多元发展模式——北京论坛（2007）

作者： randall Morck Bernard Yeung University of Alberta New York University

Corporate governance matters because how well corporations utilize the people’s savings *** developed economies mandate that corporations be run for their public *** is not because shareholders are superior to employees,bankers,bondholders,customers, suppliers,or anyone ***,it is because poor governance usually harms public shareholders before it harms *** engineered disclosure rules make corporations transparent,so poor governance quickly depresses share prices,alarming shareholders who demand corrective measures. Ideally,all this happens before the problem grows large enough to harm employees,customers,or other *** corporations for shareholders really amounts to‘using’ shareholders as early warning alarms and automatic correction *** sound government policies are necessary,for this works if corporations are rendered transparent and public shareholders are empowered to force *** stakeholders cannot fulfill this role as well because shareholders’ wealth is most directly tied to the firm’s economic efficiency.

Open Journal of Gastroenterology 2014年第5期4卷 216-220页

作者： John Vizuete John Alvarez Charles randall Department of Internal Medicine UT Health Science Center San Antonio San Antonio USA

The range and distribution of sources of lower gastrointestinal bleeding (LGIB) seem to be evolving over time. Ischemic colitis (IC) has long been recognized as a common cause of LGIB. Due to a variety of contributing factors, we suspect that IC may be implicated in an increasing proportion of inpatient cases of lower GI bleeding compared to previously published rates. We examined the medical records of 464 patients admitted to the Methodist Hospital from 2005 to 2013. Patients with LGIB admitted to the hospital with a diagnostic colonoscopy were eligible for the study. Demographics and diagnoses were grouped and categorized for ease of comparison and compatibility with prior studies. Statistical analysis was used to summarize disease distribution and calculate probability outcomes based on pooled mean values obtained from 6 previously published epidemiological studies of LGIB. Anorectal bleeding including hemorrhoids, fissures, and stercoral ulcers was the most frequent diagnosis overall (20%) followed by ischemic colitis (16%) and diverticulosis (14%). There were a significantly higher proportion of IC cases observed in our population compared to the expected proportion of cases (p < 0.01, 95%). When stratified by sex, IC was the leading overall cause in females.

Although mutations in cell cycle regulators or spindle proteins can perturb chromosome segregation, the causes and consequences of spontaneous mitotic chromosome nondisjunction in human cells are not well understood. It has been assumed that nondisjunction of a chromosome during mitosis will yield two aneuploid daughter cells. Here we show that chromosome nondisjunction is tightly coupled to regulation of cytokinesis in human cell lines, such that nondisjunction results in the formation of tetraploid rather than aneuploid cells. We observed that spontaneously-arising binucleated cells exhibited chromosome missegregation rates up to 166-fold higher than the overall mitotic population. Long-term imaging experiments indicated that most binucleated cells arose through a bipolar mitosis followed by regression of the cleavage furrow hours later. Nondisjunction occurred with high frequency in cells that became binucleated by furrow regression, but not in cells that completed cytokinesis to form two mononucleated cells. Our findings indicate that nondisjunction does not directly yield aneuploid cells, but rather tetraploid cells which may subsequently become aneuploid through further division. The coupling of spontaneous segregation errors to furrow regression provides a potential explanation for the prevalence of hyperdiploid chromosome number and centrosome amplification observed in many cancers.

鹌鹑的饲养管理

中国家禽 2007年第21期29卷 50-51页

作者： Maurice randall Gerry Bolla

　　1 前言　　鹌鹑是一种比较难饲养的禽,一般饲养在小笼子里.鹌鹑虽易感染普通禽病,但是具有相当的抵抗力.鹌鹑大约6周龄性成熟,通常在50日龄时达到高产期.只要管理适当,鹌鹑能够在产蛋第一年产200个蛋.生命周期为2～2.5年.　　……
