Polymorphisms of xenobiotic-metabolizing genes and colorectal cancer risk in patients with lynch syndrome: A retrospective cohort study in Taiwan.

abstract：:The effects of ultrasound on the cytoskeleton, comprising microtubules, had been studied decades ago. Nonetheless, very little attention has been paid to the effects of ultrasound on the mitotic spindle, which is also formed by microtubules. In this study, we treated human fibroblasts and human cancer cells (HeLa and ...
