965 results about "Cell cycle" patented technology

The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to duplication of its DNA (DNA replication) and division of cytoplasm and organelles to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells. In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and undergoes DNA replication preparing it for cell division. During the mitotic phase, the replicated chromosomes and cytoplasm separate into two new daughter cells. To ensure the proper division of the cell, there are control mechanisms known as cell cycle checkpoints.

Few seconds beam on time, breathing synchronized image guided all fields simultaneous radiation therapy combined with hyperthermia

This invention relates to single session image guided all field simultaneous radiation therapy combined with hyperthermia. Hyperthermia renders the radiation resistant cells as more radiation sensitive cells. The high and super-high dose rate radiation greatly improves the RBE of the photon radiation. It also minimizes photon radiation therapy's OER and cell cycle dependent tumor cell kill by minimizing the repair capacity of cell after photon radiation. Single session hyperthermia and radiation therapy overcomes the thermotolerance-associated inefficiency of hyperthermia treatment as it is when hyperthermia is combined with fractionated, lower dose rate radiation. The synergetic effects of sublethal damage repair inhibiting single session hyperthermia-combined with high dose and dose rate single session radiation therapy, and combined chemotherapy brings the photon radiation therapy's tumor cure and control capabilities closer to high LET radiation therapy.
