enzymes and its relation to glucose metabolism by hepa toma call lines grown in culture. Systematic analyses con camningenzymes involved in glucose metabolism of hepa tomas grown in vitro are scarce. Apart from studies of the activities or isozyma patterns of some enzymes in individual hapatoma call lines (9, 21, 34), only one enzyme involved in carbohydrate metabolism , i.e. , phosphoenolpymuv...

'DEAD/H' DNA and RNA helicases constitute a vast superfamily, with both prokaryotes, eukaryotes and viruses encoding numerous members involved in various aspects of genome replication, repair and expression (1, 2). Recently a variety of eukaryotic proteins with similarity to yeast protein Snf2 have been described (3-8), some of them involved in transcription regulation (Snf2, Sthl, YAL001, and ...

BACKGROUND AND OBJECTIVE With the increasing use of laser resurfacing, concerns have arisen about the biological hazards associated with the procedure. This study analyzed the potential bacterial and viral exposure to operating room personnel as a result of the laser smoke plume in CO2 laser resurfacing. STUDY DESIGN/MATERIALS AND METHODS Thirteen consecutive patients underwent CO2 laser resu...

Background: Hepatocellular carcinoma (HCC), primary liver cancer, is a major health problem and the third most common cause of cancer-related deaths worldwide. Epigenetic modulations are essential for the maintenance of gene expression patterns in mammals. Disruption of these processes can lead to silenced gene and malignant cellular transformation. The current study was designed to compare the...
