The effect of 20-week continuous 60 Hz magnetic field exposure on testicular function in sprague-dawley rats.

Accumulating evidence does not yet confirm the effect of power line frequency magnetic field (MF) on human health and fertility. We recently reported that, at continuous 60 Hz MF exposure in mice, the dose given as magnetic flux density (tesla; T) and duration of exposure was related to induce testicular germ cell apoptosis. We aimed to characterize the effect of a 20-week continuous exposure to 60 Hz MF on the motility, morphology, and number of sperm as well as the apoptosis of testicular germ cell in rats.

Tyr42 phosphorylation of RhoA GTPase promotes tumorigenesis through nuclear factor (NF)-κB.

Dysregulation of reactive oxygen species (ROS) levels is implicated in the pathogenesis of several diseases, including cancer. However, the molecular mechanisms for ROS in tumorigenesis have not been well established. In this study, hydrogen peroxide activated nuclear factor-κB (NF-κB) and RhoA GTPase.

Familial Creutzfeldt-Jakob disease with a mutation at codon 180 presenting with an atypical phenotype.

The clinical features of familial Creutzfeldt-Jakob disease (fCJD) with a mutation at codon 180 (V180I) are less typical than those of patients with sporadic CJD. We describe a patient with pathologically confirmed CJD carrying the V180I mutation who had atypical cerebrospinal fluid and electroencephalography findings. Similar to other prion protein mutations, this report suggests that the V180I mutation is not the exclusive determinant of the phenotype.
