The course of adult intellectual development.

A program of research is summarized that represents the author's lifelong efforts to understand the adult life course of intellectual abilities. The Seattle Longitudinal Study has assessed mental abilities in more than 5,000 adults and has followed some for as long as 35 yrs. Integrative findings are provided on patterns and magnitudes of age changes, cohort differences, factor structure of mental abilities, antecedents for individual differences in aging trajectories, and interventions designed to remediate cognitive aging efforts.

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
