Depolarization of the sarcolemma of smooth muscle cells activates voltage-gated Ca2+ channels, influx of Ca2+ and activation of cross-bridge cycling by phosphorylation of myosin catalysed by Ca2+/calmodulin-dependent myosin light-chain kinase (MLCK). Agonist stimulation of smooth muscle contraction often involves other kinases in addition to MLCK. In the(More)
Rho-associated kinase (ROK) activation plays an important role in K +-induced contraction of rat caudal arterial smooth muscle (Mita et al., Biochem J. 2002; 364: 431–40). The present study investigated a potential role for tyrosine kinase activity in K +-induced RhoA activation and contraction. The non-selective tyrosine kinase inhibitor genistein, but not(More)
We report a case of intracranial osteoma attached to the dura. The patient, a 35-year-old man, had suffered several episodes of vertigo over the previous two years. Physical and neurological findings on admission were unremarkable. A plain craniogram showed a dense calcified mass in the right frontal area, and CT revealed a homogeneous high-density mass(More)
A case of Goldenhar's syndrome associated with fifth, seventh, and eighth nerve involvement is described. Tomographic examination of the temporal bones showed evidence of an abnormal internal auditory meatus. Otoneurological examination suggested that involvement of the seventh and eighth nerves was closely related to the abnormality in the internal(More)
