Isolation of porcine circovirus-like viruses from pigs with a wasting disease in the USA and Europe

Sinus pericranii is an anomalous extracranial vascular malformation that is in continuity with the intracranial dural venous sinuses. Five case reports, three congenital and two traumatic, are described. Clinical management, including evaluation, diagnosis, and treatment, is discussed. Awareness of this entity by plastic surgeons will allow for earlier diagnosis and appropriate surgical management, resulting in decreased risk of complications.     

Evaluation of the aortic root by MRI: insights from patients with homozygous familial hypercholesterolemia

Hepatitis C chronically infects approximately 1.5% of Americans and is the most common clinical problem facing hepatologists. Since the virus was initially described in 1989, development of an effective therapy has been challenging. Although several different therapeutic agents have been used, no therapy has been shown to reliably eradicate the virus. Interferon-alpha, a cytokine with immunostimulatory and anti-viral properties, has become the therapy of choice for patients with chronic hepatitis C infection. Trials assessing the efficacy of interferon-alpha have characterized host and viral factors predictive of responses to treatment. A thorough understanding of these predictive factors is requisite to providing cost-effective therapeutic decisions for the patient with chronic hepatitis C infection.     

工业固体核磁Magmonitor用于聚烯烃质量参数测试方法的建立

利用实际采集的系列试样 ,在工业固体核磁Magmonitor(IMR)上建立了标准曲线 ;在IMR上运行标样的核磁信号后 ,对FID信号与实验数值之间的匹配使用 32个误差分析因子进行分析 ,并在Cregcon软件下运行回归分析 ,将结果转化成仪器预测模型。结果表明 ,测试相对偏差在 10 %以内 ,数据重现性好 ,而粉料与共聚物的测试误差有待改进。将IMR测试结果与不同测试方法进行比较 ,建议测试前对粉料进行脱气与脱水处理     

Application of infrared reflectance spectroscopy to the analysis of milk and dairy products

A method for the rapid, simultaneous determination of protein, fat, carbohydrate, non-protein nitrogen and total solids in milk and liquid dairy products by infrared reflectance spectroscopy is presented. The method is calibrated against known standards obtained by conventional, time-consuming wet chemical methods but, once calibrated, can be operated routinely by non-skilled personnel. The method is sensitive and accurate down to 0·5% w/v and can be applied to most liquid samples without any need for prior preparation.     

Role of Pits in Corrosion Fatigue of Offshore Structural Steel

From the corrosion fatigue test under intermit-tent wetting condition for offshore structural steelof A537 cl.l and data analysis,some results associ-ated with the role of pits in fatigue process havebeen discussed.
