Systemic lupus erythematosus is an autoimmune connective tissue disorder that affects multiple organs. While the clinical manifestations may vary in intensity over time and be associated with chronic disease, occasional cases occur where sudden and unexpected death has occurred. Cardiovascular disease is common, with accelerated atherosclerosis, intravascular thrombosis associated with antiphospholipid syndrome, and hypertensive cardiomegaly. Vasculitis with superimposed thrombosis may result in critical reduction in blood to vital organs, such as the heart and brain with infarction. Mesenteric ischemia may be caused by vasculitis, thrombosis, and accelerated atherosclerosis and may result in lethal intestinal infarction. Other diverse causes of sudden death include myocarditis, epilepsy, pulmonary hypertension, pulmonary thromboembolism, and sepsis. The autopsy evaluation of such cases requires careful examination of all organs with extensive histological sampling to include blood vessels, and microbiological sampling for bacteria, viruses, and fungi. 相似文献

This paper analyzes the competitive significance of advance price announcements. In the model, advance price announcements are used by firms to communicate private information on demand or cost. By so sharing the information, the firms are able to set their prices at more profitable levels. When the advance price announcements resolve demand uncertainty, profits rise and consumer surplus falls. Interestingly, when the advance price announcements resolve cost uncertainty, both profits and consumer welfare rise. Finally, we examine U.S. antitrust policy regarding price announcements. 相似文献

Benign prostatic hyperplasia with chronic bladder outlet obstruction has been associated with deep venous thrombosis (DVT) and fatal pulmonary thromboembolism (PTE). To evaluate this further, 60 autopsy cases of men with PTE were compared with 60 age-matched controls. The criteria for outlet obstruction were macroscopic prostatic enlargement with bladder trabeculation and benign prostatic hyperplasia on microscopy. Ten of the 60 men (16.7%) with fatal PTE had evidence of bladder outlet obstruction (age 57-78 years; mean 71.4 years). Of the 60 controls, 12 had evidence of bladder outlet obstruction (20%) (age 67-86 years; mean 75.5 years). No significant relationship could be demonstrated between bladder outlet obstruction and fatal PTE cases (p = 0.8). Given reports of this association, however, it is possible that bladder distension with venous compression may act as a risk modifier in certain individuals in association with other significant comorbidities, but this risk appears low. 相似文献

Review of the Australian National Coronial Information System and the Swedish National Forensic Database was undertaken over a 7-year period from 2001 to 2007 for all cases where death had been attributed to autoerotic death or sexual asphyxia. In Australia, there were 44 cases (M:F = 42:2) with the majority of victims aged >30 years (77%)-a yearly national rate of approximately 0.3/million. In Sweden, there were nine cases (M:F = 9:0) with the majority of cases aged <30 years (55%)-a yearly national rate of approximately 0.14/million. The usual male predominance was present in both populations, although the Australian victims were older than is usually reported. Lethal sexual asphyxia is uncommon in both the Australian and Swedish populations, with a lower rate than has been cited for North America. Whether this is because of different kinds of paraphilic activities in different populations or of differences in methods of central data collection is uncertain. 相似文献

A review of articles in the technical media between 2005 and 3Q 2011 disclosed reports on 49 outages involving 20 cloudsourcing providers. Several of these were major events. Many caused difficulties for user-organisations’ staff. Some caused lengthy suspension of services by user-organisations to their customers. A number of them involved irretrievable loss of data. Many user-organisations have failed to risk-assess their use of cloudsourcing, and are exposing their businesses to unmanaged risks. 相似文献

This paper compares and evaluates the accuracy of long-range occupational manpower forecasts made for 1980 in the early 1970s by the U.S. Bureau of Labor Statistics and by the author. The different assumptions and forecasting methodologies utilized are discussed, and the occupational forecasts are then compared to the actual 1980 employment data. The relative accuracy of the different sets of forecasts is assessed according to several different criteria, and the larger question of the usefulness of either set of forecasts is addressed. It is found that neither set of forecasts was clearly superior, that the accuracy of both sets of forecasts was generally poor, and that the projections for individual occupations were often so wide of the mark as to be of questionable usefulness for manpower planning and vocational guidance. The implications of these findings for manpower forecasting are discussed. 相似文献

Somatic gene therapy is one of the most fascinating and important medical developments as well as a field bearing unknown risks in human medicine of the nineties. This article tries to give a short survey on the medical applications of this new technique on the one hand and reflects possible ethical and legal implications on the other hand. We conclude that only an international agreement on risk assessment and ethical principles will lead to a adequate approach to somatic gene therapy. 相似文献

Abstract: The time required for short tandem repeat (STR) amplification is determined by the temperature ramp rates of the thermal cycler, the components of the reaction mix, and the properties of the reaction vessel. Multiplex amplifications in microfluidic biochip-based and conventional tube-based thermal cyclers have been demonstrated in 17.3 and 19 min, respectively. Optimized 28-cycle amplification protocols generated alleles with signal strengths above calling thresholds, heterozygous peak height ratios of greater than 0.65, and incomplete nontemplate nucleotide addition and stutter of less than 15%. Full CODIS-compatible profiles were generated using the Profiler Plus ID, COfiler and Identifiler primer sets. PCR performance over a wide range of DNA template levels from 0.006 to 4 ng was characterized by separation and detection on a microfluidic electrophoresis system, Genebench-FX™ . The fast multiplex PCR approach has the potential to reduce process time and cost for STR analysis and enables development of a fully integrated microfluidic forensic DNA analysis system. 相似文献
