conclusion spiral-ct scan is superior to conventional ct in the diagnosis of lesions in com before operation. it can be used for detailed evaluation of ossicular chain in such patients. objectives this study was performed to compare the findings of three-dimensional reconstructed spiral and conventional ct scan of ossicular chain study in patients with com. patients and methods fifty patients e...

CONCLUSIONS Human neural progenitor cells can differentiate into spiral ganglion-like cells when exposed to inner ear-associated growth factors. The phenotype bears resemblance to human sphere-derived neurons. OBJECTIVE To establish an in vitro model for the human auditory nerve to replace and complement in vivo animal experiments and ultimately human in vivo transplantation. METHODS Human ...

Maternal cardiovascular adaptations occur in normal pregnancy, systemically, and within the uterus. In humans, gestational control of blood pressure is clinically important. Transient structural remodeling of endometrial spiral arteries normally occurs in human and mouse pregnancies. In mice, this depends on uterine natural killer cell function. Using normal and immune-deficient mice, we asked ...

From the photometric results presented in this communication it appears that contrary to some earlier indications the open spirals, with their supergiant stars and superficial structure of spiral arms, are not appreciably larger than spheroidal galaxies, which seem to be devoid of highly luminous stars and free of distributional irregularities. It follows that if in the course of time spiral ar...

Experiments on the formation of spiraling hexagons (350-1000 nm in width) from a solution of nanoparticles are presented. Transmission electron microscopy images of the reaction products of chemically synthesized cadmium nanocrystals indicate that the birth of the hexagons proceeds without assistance from static screw or edge dislocations, that is, they spiral without constraints provided by an...
