Large brain specimens were prepared from 50 head-injured and 50 non-head-injured cases that underwent medicolegal autopsy to critically examine the morphological changes in the periventricular tissue caused by injury to the head. Hemorrhagic damage to the ventricular wall was observed in 30 (60%) of the head-injury cases but was not observed in any of the(More)
A case where a body with unusual circular injuries was found in the sea is presented. The victim was a 60-year-old woman who had been depressed and had attempted suicide before. She was missing for 6 days before the corpse was found. The body had several almost perfectly circular injuries and C-shaped incision injuries with almost circular flaps of skin. We(More)
For the time integration of collisional -body systems, such as star clusters and systems of planetesimals, the combination of direct summation for force calculation and the individual timestep algorithm has been the standard method for nearly a half century. It is not impossible to combine an individual timestep algorithm and a fast and approximate force(More)
Liver sinusoidal endothelial cells (SECs) possess unique receptors that recognize and internalize hyaluronic acid (HA). To develop a system for targeting foreign DNA to SECs, comb-type polycations having HA side chains were prepared by coupling HA to poly(L-lysine) (PLL). The HA-grafted-PLL copolymer (PLL-g-HA) thus formed was mixed with DNA in 154 mM NaCl(More)
