The fission of a cell. The division of the cytoplasm into two equal parts, usually brought about by the formation of a cell plate: mitosis; meiosis. The way in which a cell reproduces itself. A process by which a cell divides into two new cells. In cell division, the nucleus of the cell can divide…

Progressive restriction of the developmental potential and increasing specialization of function which takes place during the development of the embryo and leads to the formation of specialized cells, tissues, and organs. The process whereby descendants of a common parental cell achieve and maintain specialization of structure and function. In humans, for instance, all the different…

The termination of the cell’s ability to carry out vital functions such as metabolism, growth, reproduction, responsiveness, and adaptability.  

The complex series of phenomena, occurring between the end of one cell division and the end of the next, by which cellular material is divided between daughter cells. The sequence of events between eukaryotic cell divisions; it includes mitosis and cell division (M phase), a gap stage (G1 phase), a period of DNA synthesis (S…

Adherence of cells to surfaces or to other cells.

The cavity or cavities of an ovary or fruit containing the ovules or seeds; The pollen-sac of an anther, an anther lobe or theca; The fundamental, minute unit of all plant construction. The individual unit that…

Broad-spectrum cephalosporin antibiotic with a very long half-life and high penetrability to usually inaccessible infections, including those involving the meninges, eyes, inner ears, and urinary tract. Parenteral cephalosporin antibiotic (trade name Rocephin) indicated for severe infections of the lungs, ears, skin, urinary tract, and throat. Also used in the treatment of sexually transmitted diseases. Potential…

Factors which produce cessation of all vital bodily functions. They can be analyzed from an epidemiologic viewpoint.  

Etiology; Pertaining to a cause; directed against a cause. Responsible for bringing about a particular effect, condition, or result. For example, there is a documented causal link between cigarette smoking and an increased risk of coronary artery disease.
