Application of a high electric field causes an electric shock to the heart. This is utilized in defibrillation to reestablish normal contraction rhythms during dangerous arrhythmias or in cardiac arrest. If shock-induced transmembrane potentials are large enough, they can cause tissue destruction due to irreversible electroporation (EP). Also electrochemotherapy of nearby tissues may have an ad...

BACKGROUND Monomers of methacrylates used in restorative dentistry have been recently reported to induce DNA double-strand breaks (DSBs) in human gingival fibroblasts (HGFs) in vitro. Because such monomers may penetrate the pulp and oral cavity due to the incompleteness of polymerization and polymer degradation, they may induce a similar effect in vivo. DSBs are the most serious type of DNA dam...

ABSTRACT I: Management of invasive transitional cell human bladder carcinoma. The two main treatment options for invasive transitional cell bladder carcinoma are radiotherapy or primary cystectomy with urinary diversion or bladder substitution. Approximately 50% of patients fail to respond to radiotherapy and such patients so treated are disadvantaged by the absence of predictive information re...

We report on the discovery and analysis of a striking neutral sodium gas tail associated with comet C/1995 O1 Hale-Bopp. Sodium D–line emission has been observed at heliocentric distance r ≤ 1.4 AU in some long–period comets and the presence of neutral sodium in the tailward direction of a few bright comets has been noted, but the extent, and in particular the source, has never been clear. Here...

In this study we evaluated the genotoxic potential of surface sediment extracts of Lake Skadar using a combination of two in vitro tests: the Comet assay on the fibroblast-like permanent cell line RTL-W1, and the Ames test on the strain Salmonella typhimurium TA98. The obtained results show that both tests were successful in determining the genotoxic potential in the sediment organic fractions....

Arecibo radar imagery of Comet 8P/Tuttle reveals a 10-km-long nucleus with a highly bifurcated shape consistent with a contact binary. A separate echo component was also detected from large (>cm-size), slow-moving grains of the type expected to contribute to the Ursid meteor stream. ! 2009 Elsevier Inc. All rights reserved.
