Cell growth refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volume. [1] Cell growth occurs when the overall rate of cellular biosynthesis (production of biomolecules or anabolism) is greater than the overall rate of cellular degradation (the destruction of biomolecules via the proteasome, lysosome or autophagy, or catabolism).
Latitudinal and longitudinal growth may be affected. [1] [2] [3] Nevertheless, the musculoskeletal features are central to the diagnosis of some syndromes such as Proteus syndrome. [2] The time of presentation of children with overgrowth syndromes is an important contributor to the differential diagnosis.
Symptomatic features of paraneoplastic syndrome cultivate in four ways: endocrine, neurological, mucocutaneous, and hematological.The most common presentation is a fever (release of endogenous pyrogens often related to lymphokines or tissue pyrogens), but the overall picture will often include several clinical cases observed which may specifically simulate more common benign conditions.

The PDGFRB gene is located on human chromosome 5 at position q32 (designated as 5q32) and contains 25 exons.The gene is flanked by the genes for granulocyte-macrophage colony-stimulating factor and Colony stimulating factor 1 receptor (also termed macrophage-colony stimulating factor receptor), all three of which may be lost together by a single deletional mutation thereby causing development ...
A bioassay is an analytical method to determine the potency or effect of a substance by its effect on living animals or plants (in vivo), or on living cells or tissues (in vitro). [1] [2] A bioassay can be either quantal or quantitative, direct or indirect. [3] If the measured response is binary, the assay is quantal; if not, it is quantitative ...
Chédiak–Higashi syndrome [1] (CHS) is a rare autosomal recessive disorder that arises from a mutation of a lysosomal trafficking regulator protein, [2] which leads to a decrease in phagocytosis. The decrease in phagocytosis results in recurrent pyogenic infections, albinism , and peripheral neuropathy .
