Clinical significance of sarcopenia in children with neuroblastic tumors.

Purpose: To elucidate the clinical significance of sarcopenia in children with neuroblastic tumors (NTs).

Methods: We conducted a retrospective observational study and analyzed the z-scores for height, body weight, body mass index, and skeletal muscle index (HT-z, BW-z, BMI-z, and SMI-z) along with the clinical characteristics of 36 children with NTs. SMI-z was calculated from 138 computed tomography scans at diagnosis, during treatment, and at follow-up.

Total Synthesis of Sekothrixide Strategically Utilizing Regioselective Coupling of TMS-Protected Epoxy sec-Alcohol with Gilman Reagent.

A new efficient synthesis of sekothrixide was established on the basis of our developed regioselective coupling of epoxy sec-alcohol with Gilman reagent guided by a TMS group. The new synthetic route allowed an overall yield of 6.3% (26 steps) from optically active 3-silyloxy-2-methylaldehyde.
