【正文】 e. Chronological(編年的 )age doesn’t always match biological age,” said Shadyab, PhD, lead author of the study. Shadyab and his research team believe they are the first to objectively measure how the bination of sedentary time and exercise can influence the aging biomarker. Nearly 1,5000 women, ages 64 to 95, participated in the study. The participants pleted questionnaires and wore an accelerometer on their right hip for seven consecutive days during waking and sleeping hours to track their movements. “We found that women who sat longer did not have shorter telomere length if they exercised for at least 30 minutes a day, the national remended guideline,” said Shadyab. “Discussions about the benefits of exercise should start when we are young, and physical activity should continue to be part of our daily lives as we get older, even at 80 years old.” Shadyab said future studies will examine how exercise relates to telomere length in younger populations and in men. 28.

Though details of the meeting as to what was specifically discussed remain sketchy, it is a positive signal for ChinaUS trade relations under Trump, following the recent turbulence(動蕩 ), according to Bai Ming, a research fellow at the Chinese Academy of International Trade and Economic Cooperation. “This is sign that Trump is leaving the door open for pragmatic cooperation with Chinese firms, which he thinks could help the US economy and create jobs.” Bai told the Global Times. It is important that ALibaba strikes a balance between expanding overseas and strengthening its base in China, Mei noted. Bai said the meeting also offers a pattern that other Chinese panies can follow in expanding to the US under Trump. “They have to stress how many jobs you can create in the US in talking with Trump,” he said. 32.
