Sudden and unexpected death of a 6-month-old baby with silent heart failure due to anomalous origin of the left coronary artery from the pulmonary artery.

A 6-month-old girl died suddenly without any previous symptoms of heart failure. Autopsy examination showed cardiomegaly (97 g) with a severely fibrotized myocardium. The left coronary artery was originating from the pulmonary artery. Histologically, the myocardium showed myocardial infarcts of different ages, as well as grossly thickened arterial branches due to increased flow in left-right shunt. We suggest that rare anomalies of the coronary arteries should be considered in the autopsies of suspected sudden infant death syndrome cases.     

Impact of tropical conditions on thin layer chromatography in analytical toxicology: high temperatures and moderate humidities.

The impact of high temperatures (24 to 39 degrees C) and low to moderately high humidities (20 to 70%) on the applicability of TLC systems for drug identification was studied during a 6 month climatologic cycle in Burkina Faso (West Africa). In general, the Rf values as observed on the plates were found to be substantially affected as compared with values obtained at temperate climates. Some TLC systems were more affected than others and the largest deviations of up to 30 Rf units were at low humidities. Tropical conditions also had a negative effect on the reproducibility of Rf values. However, when an Rf-correction procedure was applied, using reference mixtures of known drugs on each plate, accuracy as well as reproducibility of the resulting Rfc values were drastically improved and data thus corrected were found to be compatible with existing TLC data bases developed under moderate climatological conditions. The impact of high to extremely high humidities (70 to 100%) remains to be investigated.

Who Owns Your Body? A Patient''s Perspective on Washington University v. Catalona

Washington University v. Catalona revolves around ownership of tissue samples provided by patients for research purposes, raising significant ethical and legal questions concerning patient rights, current human research practices, and the treatment of samples as capital resources by the research institution.     

他信家族售股引发泰国政坛动荡

1月24日,泰国总理他信家族将所持有的西那瓦集团49.6%的股份出售给新加坡淡马锡控股,这笔原本要价10.5亿美元的交易最后以18.7亿美元成交.作为西那瓦集团的最大股东,他信年仅23岁的大女儿得到5.3亿美元.这起貌似普通的交易有着复杂的背景,他信本想通过此次交易证明自己的清白,不料却引发了泰国大规模反对他信的游行,使他面临从政以来最大危机.     

Organic impurity profiling of 3,4-methylenedioxymethamphetamine (MDMA) tablets seized in The Netherlands.

In this study, a new method was developed for the impurity profiling of illicit MDMA tablets. The extraction efficiency, linearity, repeatability and reproducibility of the method were evaluated. Eighty two MDMA tablets coming from presumed unrelated large seizures in 2004 (n >500 tablets) were analyzed by gas chromatography mass spectrometry (GC-MS) in order to assess the discrimination power of the method. The latter was found to be practical, robust, relatively easy to perform, highly discriminative and yielding good chromatography. In addition, some new impurities were detected and identified. Their chemical structures and mass spectra are reported.     

“天花板现象“与女性领导胜任力的保障、培育与开发

女性参与和组织公共事务管理活动,是妇女参与的最高形式,在当今世界被视为提高妇女地位的重要方面,也是衡量一个国家社会发展和文明进步的标志之一。但是,我国女性在职务晋升中还存在着只能担任低层职务,或者做到一定职位后便再难晋升的"玻璃天花板"现象。本文分析了这一现象的表现、形成根源,并提出了通过提高女性领导胜任力克服"玻璃天花板"现象的对策措施。     

Influence of electricity on post-mortal body temperature

In a case of suicidal application of electricity differences between the rectal temperature of the body and the suspected time of death were observed.In order to answer the question whether an electric current from hand to hand over >30 min led to a rise in body temperature FEM-based computer simulations and animal experiments were carried out. Both resulted in a warming of the soft parts in the arm without warming the body core. Thus a temperature-based estimation of the time since death can also be used in cases with electricity as the cause of death. Besides, in the animal experiment we found a spontaneous rise in the body core temperature even without application of electricity which may be a reason for the typical temperature plateau after death.
