Cold-inducible RNA-binding protein (Cirp) interacts with Dyrk1b/Mirk and promotes proliferation of immature male germ cells in mice.

Cold-inducible RNA-binding protein (Cirp) was the first cold-shock protein identified in mammals. It is structurally quite different from bacterial cold-shock proteins and is induced in response to mild, but not severe, hypothermia. To clarify the physiological function of Cirp in vivo, we produced cirp-knockout mice.

Extraperitoneal laparoscopic ureterolithotomy in the supine position for impacted ureteral stones.

We describe initial experiences with extraperitoneal laparoscopic ureterolithotomy in the supine position. This method can provide adequate working space without the risk of mechanical bowel injury and nerve stretching specific to the flank position.

[Spontaneous rupture of infected renal cyst presenting sudden onset of right flank distension: a case report].

A 21-year-old woman was referred to our hospital for sudden onset of right flank distension. Ultrasonography, abdominal CT scan and MRI revealed a giant cyst 20 x 11 x 10 cm on the right kidney. Percutaneous puncture of the lesion was performed and fluid was drained.
