Lipoatrophy is the term describing the localized loss of fat tissue. This may occur as a result of subcutaneous injections of insulin in the treatment of diabetes , from the use of human growth hormone or from subcutaneous injections of copaxone used for the treatment of multiple sclerosis .
Poly-L-lactic acid (PLLA) is the main ingredient in Sculptra, a facial volume enhancer used for treating lipoatrophy of the cheeks. PLLA is used to stimulate collagen synthesis in fibroblasts via foreign body reaction in the presence of macrophages.
In a sense, the "opposite" of injection site lipohypertrophy is injection site lipoatrophy, in which the subcutaneous fat around an injected area "melts away" over a few weeks or months, leaving unsightly, well-demarcated depressions in the skin. The mechanism of this local lipoatrophy is not understood and may involve autoimmunity or local ...
Acquired generalized lipodystrophy (AGL), also known as Lawrence syndrome [1] and Lawrence–Seip syndrome, [1] is a rare skin condition that appears during childhood or adolescence, characterized by fat loss affecting large areas of the body, particularly the face, arms, and legs.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Bioanalysis is a sub-discipline of analytical chemistry covering the quantitative measurement of xenobiotics (drugs and their metabolites, and biological molecules in unnatural locations or concentrations) and biotics (macromolecules, proteins, DNA, large molecule drugs, metabolites) in biological systems.
This research provides new insights into how various factors control muscle growth and maintenance, which could help develop better ways to prevent muscle loss in the future. Understanding BCL6 as ...
Lipophilic efficiency [1] (LiPE), sometimes referred to as ligand-lipophilicity efficiency (LLE) is a parameter used in drug design and drug discovery to evaluate the quality of research compounds, linking potency and lipophilicity in an attempt to estimate druglikeness.
