Closed timelike curve. In mathematical physics, a closed timelike curve (CTC) is a world line in a Lorentzian manifold, of a material particle in spacetime, that is "closed", returning to its starting point. This possibility was first discovered by Willem Jacob van Stockum in 1937 [ 1 ] and later confirmed by Kurt Gödel in 1949, [ 2 ] who ...
Circulating tumor cell. An illustration depicting primary tumor (in the form of tumor microenvironment) and the circulating tumor cells. A circulating tumor cell (CTC) is a cell that has shed into the vasculature or lymphatics [1] from a primary tumor and is carried around the body in the blood circulation. CTCs can extravasate and become seeds ...
Cell mechanics. Cell mechanics is a sub-field of biophysics that focuses on the mechanical properties and behavior of living cells and how it relates to cell function. [1] It encompasses aspects of cell biophysics, biomechanics, soft matter physics and rheology, mechanobiology and cell biology.
CTCF. Transcriptional repressor CTCF also known as 11-zinc finger protein or CCCTC-binding factor is a transcription factor that in humans is encoded by the CTCF gene. [5][6] CTCF is involved in many cellular processes, including transcriptional regulation, insulator activity, V (D)J recombination [7] and regulation of chromatin architecture.
Phases of clinical research. The phases of clinical research are the stages in which scientists conduct experiments with a health intervention to obtain sufficient evidence for a process considered effective as a medical treatment. [1] For drug development, the clinical phases start with testing for drug safety in a few human subjects, then ...
Cell-count distribution featuring cellular differentiation for three types of cells (progenitor , osteoblast , and chondrocyte ) exposed to pro-osteoblast stimulus. [1] Cellular differentiation is the process in which a stem cell changes from one type to a differentiated one. [2][3] Usually, the cell changes to a more specialized type.
Cell culture is also a key technique for cellular agriculture, which aims to provide both new products and new ways of producing existing agricultural products like milk, (cultured) meat, fragrances, and rhino horn from cells and microorganisms. It is therefore considered one means of achieving animal-free agriculture.
Angela Grassi, Founder of PCOS Nutrition Center, went untreated for three decades. Grassi says it’s extremely common for doctors to tell patients that their PCOS will “go away” or get better ...
