BACKGROUND Newer models of cardiac rehabilitation(CR)delivery are promising but depend upon patient participation and ability to use technological media including Internet and smart devices.AIM To explore the availability of smart devices,current utilization and proficiency of use among older CR program attendees.METHODS Study participants were enrolled from four CR programs in Omaha,Nebraska United States and completed a questionnaire of 28 items.RESULTS Of 376 participants approached,169 responded(45%).Mean age was 71.1(SD±10)years.Demographics were 73.5%males,89.7%Caucasians,52%with college degree and 56.9%,with income of 40 K$or more.Smart device ownership was84.5%;desktop computer was the most preferred device.Average Internet use was 1.9 h/d(SD±1.7);54.3%of participants indicating for general usage but only18.4%pursued health-related purposes.Utilization of other health information modalities was low,29.8%used mobile health applications and 12.5%used wearable devices.Of all participants,72%reported no barriers to using Internet.Education and income were associated positively with measures of utilization and with less perceived barriers.CONCLUSIONAmong an older group of subjects attending CR,most have access to smart devices and do not perceive significant barriers to Internet use.Nonetheless,there was low utilization of health-related resources suggesting a need for targeted education in this patient population. 展开更多

目前古代淀粉粒鉴别的两种方法,即显微镜观察法和碘着色测试法,均不能确保鉴别的准确性。针对耐热性α-淀粉酶只对淀粉产生降解的特点,设计出古代淀粉粒鉴别的"耐热性α-淀粉酶降解法",并运用到考古样品中淀粉粒的分析和鉴定... 目前古代淀粉粒鉴别的两种方法,即显微镜观察法和碘着色测试法,均不能确保鉴别的准确性。针对耐热性α-淀粉酶只对淀粉产生降解的特点,设计出古代淀粉粒鉴别的"耐热性α-淀粉酶降解法",并运用到考古样品中淀粉粒的分析和鉴定之中。本文详细介绍了耐热性α-淀粉酶降解法的原理和流程,并通过古代淀粉粒的鉴别实验,确定了该方法在确切鉴别考古样品中淀粉粒的实用性和有效性;同时现代大麦和莲藕淀粉粒的降解实验结果表明不同植物来源以及同种植物内部不同粒径的淀粉粒其降解速率存在明显差异,而古代淀粉粒在耐热性α-淀粉酶作用下出现的降解速率差异的现象,或可揭示古代淀粉粒的植物来源,甚至长期埋藏对其产生的影响。 展开更多
