When comparing SMILE with LASIK, myopia was greater than -6.00 D, and the corneal hysteresis, corneal resistance factor, p1area, and p2area decrease was less after SMILE.

H 2 S plays important physiological and pathological roles in cardiovascular system and nervous system. But recent evidences imply that hydrogen polysulfides (H 2 S n ) are the actual signaling molecules in cells. Although H 2 S n have been demonstrated to be responsible for mediating tumor suppressors, ion channels, and transcription factors, more of their biological effects are still need to be elaborated. On one hand, H 2 S n have been suggested to be generated from endogenous H 2 S upon reaction with reactive oxygen species (ROS). On the other hand, H 2 S n derivatives are proposed to be a kind of direct antioxidant against intracellular oxidative stress. This conflicting results should be attributed to the regulation of redox homeostasis between ROS and H 2 S n . Superoxide anion (O 2 •− ) is undoubtedly the primary ROS existing in mitochondria. We reason that the balance of O 2•− and H 2 S n are pivotal in physiological and pathological processes. Herein, we report two near-infrared fluorescent probes Hcy-Mito and Hcy-Biot for the detection of O 2•− and H 2 S n in cells and in vivo. Hcy-Mito is conceived to be applied in mitochondria, and Hcy-Biot is designed to target tumor tissue. Both of the probes were successfully applied for visualizing exogenous and endogenous O 2•− and H 2 S n in living cells and in tumor mice models. The results demonstrate that H 2 S n can be promptly produced by mitochondrial oxidative stress. Flow cytometry assays for apoptosis suggest that H 2 S n play critical roles in antioxidant systems.

Inhibition of mitotic kinesins represents a novel approach for the discovery of a new generation of anti-mitotic cancer chemotherapeutics. We report here the discovery of the first potent and selective inhibitor of centromere-associated protein E (CENP-E) 3-chloro-N-{(1S)-2-[(N,N-dimethylglycyl)amino]-1-[(4-{8-[(1S)-1-hydroxyethyl]imidazo[1,2-a]pyridin-2-yl}phenyl)methyl]ethyl}-4-[(1-methylethyl)oxy]benzamide (GSK923295; 1), starting from a high-throughput screening hit, 3-chloro-4-isopropoxybenzoic acid 2. Compound 1 has demonstrated broad antitumor activity in vivo and is currently in human clinical trials.
