luteolysis definition: Regression of ovarian corpora lutea. [http://ovary.stanford.edu]
Luteolysis definition: Degradation of CORPUS LUTEUM. In the absence of pregnancy and diminishing trophic hormones, the corpus luteum undergoes luteolysis which is characterized by the involution and cessation of its endocrine function.
Neoplasm Regression, Spontaneous definition: Disappearance of a neoplasm or neoplastic state without the intervention of therapy.
Regression Analysis definition: Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
Regression Method definition: Regression analysis provides a "best-fit" mathematical equation for the relationship between the dependent variable (response) and independent variable(s) (covariates). There are two major classes of regression - parametric and non-parametric. Parametric regression requires choice of the regression equation with one or a greater number of unknown parameters. Linear regression, in which a linear relationship between the dependent variable and independent variables is posited, is an example. The aim of parametric regression is to find the values of these parameters which provide the best fit to the data. The number of parameters is usually much smaller than the number of data points. In contrast, the non-parametric regression requires no such a choice of the regression equation.
Anti-Mullerian Hormone definition: A glycoprotein that causes regression of MULLERIAN DUCTS. It is produced by SERTOLI CELLS of the TESTES. In the absence of this hormone, the Mullerian ducts develop into structures of the female reproductive tract. In males, defects of this hormone result in persistent Mullerian duct, a form of MALE PSEUDOHERMAPHRODITISM.
neoplasm/cancer remission/regression definition: diminution or abatement of the symptoms of a neoplasm or cancer.
remission/regression definition: diminution or abatement of the symptoms of a disease.
regression definition: A decrease in the size of a tumor or in the extent of cancer in the body.
Regression definition: Return to a former state; a subsidence of the symptoms of a disease process; in cancer, a decrease in the size of a tumor or in the extent of cancer in the body.
