Effects of core strength training on core stability.

[Purpose] To investigate the effects of core strength training on core stability with and without the Valsalva maneuver. [Participants and Methods] Twenty-four students were randomly assigned to the training and control groups. Students in the training group undertook a 4-week training program that included exercises for the transverse abdominis, multifidus, diaphragm, and pelvic floor muscles, whereas students in the control group performed their usual activities.

LSD1/KDM1A promotes hematopoietic commitment of hemangioblasts through downregulation of Etv2.

The hemangioblast is a progenitor cell with the capacity to give rise to both hematopoietic and endothelial progenitors. Currently, the regulatory mechanisms underlying hemangioblast formation are being elucidated, whereas those controllers for the selection of hematopoietic or endothelial fates still remain a mystery. To answer these questions, we screened for zebrafish mutants that have defects in the hemangioblast expression of Gata1, which is never expressed in endothelial progenitors.
