Easy way of keeping hairs away while suturing ear lacerations

Suturing of lacerations of skeletal muscle.

Our aim was to compare the biomechanical properties of suturing methods to determine a better method for the repair of lacerated skeletal muscle. We tested Kessler stitches and the combination of Mason-Allen and perimeter stitches. Individual stitches were placed in the muscle belly of quadriceps femoris from a pig cadaver and were tensioned mechanically. The maximum loads and strains were meas...

Keeping RNA away from DNA

JCB • VOLUME 170 • NUMBER 6 • 2005 862 Keeping RNA away from DNA ewly transcribed RNA represents a threat to genomic stability, say Xialu Li and James Manley (Columbia University, New York, NY). They find that, in metazoan cells, the threat is neutralized by a splicing factor that coats RNA as it it emerges from RNA polymerase. The danger arises because nascent RNA can anneal to the template DN...

Epimysium and perimysium in suturing in skeletal muscle lacerations.

BACKGROUND Direct muscle belly trauma is common. Selecting optimal methods for surgical repair of muscle disruption is difficult because reliable methods have not been established. Suturing tendon offers strong repairs, but epimysium and perimysium, the connective tissues that coalesce to form tendons, offer unknown repair strength. The purpose of this study was to compare biomechanical propert...
