Virtual Data Rooms (VDRs) are safe and reliable methods to access confidential documents during business transactions. VDRs can be used to perform due diligence in mergers and acquisitions. They also assist businesses organize important documents and share them with investors and other stakeholders. VDRs can also be used to organize and store invoices, contracts and other documents, for legal reasons such as litigation or estate planning.
Members should examine the procedures and equipment installed on their vessels with a VDR/SVDR. It is also recommended to take the opportunity to think about upgrading and changing the equipment that is outdated or do not meet minimum safety requirements.
The active form of vitamin D, 1,25-dihydroxyvitamin D (1,25(OH)2D), binds to the vitamin D receptor (VDR) and retinoid X receptor (RXR) to form heterodimers that act on gene promoter regions known as vitamin D response elements. These genes regulate the expression of proteins that are involved in a myriad of physiological processes.
The VDR can be found in neurons, cells of glial origin, and subsets of them that make up the brain. In the primary hippocampal cells of rats, VDR immunoreactivity was detected in the oligodendrocytes. The VDR also appears to be present in human neuroblastoma and astrocytes. Treatment of HL-60 myeloblastleukemia cells with 1,25(OH)2D3 resulted in monocyte-like differentiation, which was accompanied by increased VDR protein levels. This effect was inhibited by inhibitors of the PI3-K and MAPK pathways. In addition, VDR expression was increased in oligodendrocytes treated with 12-O-tetradecanoylphorbol-13-acetate (TPA) to induce megakaryoblastic leukemia cell maturation.
