Mechanisms of genesis and growth of calculi
The American Journal of Medicine, 1968Abstract The purpose of this discussion is to examine some of the stone-forming mechanisms at the basic level. An attempt is made to consider three persistent root questions: (1) What is the physicochemical mechanism by which stone material is synthesized or put together?

From a biologist’s perspective, growth is mediated by gene activation and regulation. In a simplified view, different genes will trigger different growth responses.

Molecular Mechanisms of Axonal Growth
2008Outgrowth of axons during neuronal development, as well as their regeneration after injury, of the adult nervous system is controlled by specific extracellular cues which are diffusible, or bound to cell membranes or extracellular matrix. The exact molecular mechanisms through which these extracellular signals are integrated by the growing axon, are ...

A general mechanism of polycrystalline growth
Nature Materials, 2004Most research into microstructure formation during solidification has focused on single-crystal growth ranging from faceted crystals to symmetric dendrites. However, these growth forms can be perturbed by heterogeneities, yielding a rich variety of polycrystalline growth patterns.

Mechanisms of Endothelial Growth Control
American Journal of Respiratory Cell and Molecular Biology, 1992Abstract It is well documented that vascular endothelial cells constitute an unusually quiescent epithelial cell population. These slowly dividing cells are known to undergo more rapid division in association with wound healing as well as a variety of pathologic conditions such as tumor vascularization and diabetic retinopathy ...

Mechanisms of reduced and compensatory growth
Domestic Animal Endocrinology, 2000Growth is an integrated process, resulting from the response of cells dependent on the endocrine status and nutrient availability. During feed restriction, the production and secretion of growth hormone (GH) by the pituitary gland are enhanced, but the number of GH receptors decreases.

Mechanical modeling of pimple growth
Journal of the Mechanical Behavior of Biomedical Materials, 2019Pimple is one of the most common skin diseases for humans, whose growth cause pain yet the corresponding mechanical analysis is lacking. A finite element model is developed to quantify the deformation field with the expansion of follicle, and then the mechanical stimulus is related to the sensation of pain during the development of pimple.

Growth Mechanisms and Cancer Progression
Hospital Practice, 1993In the final stages of malignant progression, tumor cell growth mechanisms become self-contained, making the cells impervious to attempts at growth control by physicians or the host. Such tactics might work better in the early stages of metastasis, when these cells are still responsive to outside influences.
