  Use of Muscle Functional Magnetic Resonance Imaging With Older Individuals

  摘要：

  Muscle functional magnetic resonance imaging (mfMRI) has been widely used to study muscle recruitment in exercise in young healthy subjects, but has not been validated or used with older subjects. This study validates and demonstrates the use of mfMRI in older subjects. Subjects consisted of apparently healthy sedentary younger (n = 7) and older (n = 6) women. Proton transverse relaxation (T2)-weighted MRI scans were obtained of the quadriceps femoris at rest and immediately following three bouts of knee extension exercise (50%, 75%, and 100% of untrained 5 x 10 repetition maximum [RM]). Older subjects performed knee extension training for 12 weeks and repeated the MRI scan protocol using the same absolute loads. Training induced a 13% increase in 1 RM and a 25% increase in 5 x 10 RM. Older subjects had higher resting T2 values compared with younger subjects; however, the T2 response to exercise (slope) was similar among groups (young = 0.063 +/- 0.003, older untrained = 0.055 +/- 0.011, older trained = 0.053 +/- 0.008; p > .05). In all cases, T2 increased Linearly with load. Trained older subjects showed a lower T2 response when lifting the same absolute load compared with before training, which is consistent with results previously obtained from young subjects. In the older population, mfMRI is appropriate for use and offers benefits over other technologies.

  EZH2 or EZH1 (enhancer of zeste homologue 2 or 1) is the catalytic subunit of polycomb repressive complex 2 (PRC2) that catalyzes methylation of histone H3 lysine 27 (H3K27). PRC2 hyperactivity and/or hypertrimethylation of H3K27 are associated with numerous human cancers, therefore inhibition of PRC2 complex has emerged as a promising therapeutic approach. Recent studies have shown that EZH2 and EZH1

  EZH2或EZH1（zeste同源物2或1的增强剂）是多梳抑制复合物2（PRC2）的催化亚基，可催化组蛋白H3赖氨酸27（H3K27）的甲基化。PRC2的过度活跃和/或H3K27的过度三甲基化与许多人类癌症相关，因此抑制PRC2的复合体已成为一种有前途的治疗方法。最近的研究表明，EZH2和EZH1在功能上不是多余的，抑制EZH2和EZH1两者对于阻止某些癌症（如混合谱系白血病（MLL）重排的白血病）的进展是必要的。尽管EZH2抑制剂的发现取得了重大进展，但尚未进行系统的结构-活性关系（SAR）研究来研究EZH2和EZH1抑制剂之间的选择性。这里，5）研究结构变化对EZH2和EZH1抑制和选择性的影响。

• Does Age Change the Distribution of Visual Attention? A Comment on McCalley, Bouwhuis, and Juola (1995)

  A paper, by McCalley, Bouwhuis, and Juola (1995) suggested differences between younger and older adults in the use of visual cues. Furthermore, they reported these differences could largely be attributed to diminished (peripheral al) visual proressing capacities of elderly adults. I-It re, we reanalyze the data of McCalley and colleagues emphasizing relative rather than absolute differences. We find that when doing so, the data do not reveal differences in the way older and younger adults transiently allocate attention during visual search. Contrary to the conclusions of McCalley and colleagues, the similarity between the younger and older observers is therefore independent of the characteristics of the visual information. Furthermore, in our view the data suggest that older adults have foveal rather than peripheral visual processing difficulties. The results reemphasize the importance of the analytical approach taken in aging research, We discuss the difficulties and relevance of controlling and separating visual and attentional factors in age-related studies.
