The surface epithelial cells of the small intestine are renewed rapidly and regularly. It takes about two days for the cells of the duodenum to be renewed completely. As a result of its rapid renewal rate, the intestinal epithelium is susceptible to various factors that may influence proliferation. Exposure of the intestine to ionizing radiation and cytotoxic drugs (such as folic acid antagonists and colchicine) reduces the cell renewal rate.

Dr Joan Ogden is Professor of Environmental Science and Policy at the University of California, Davis, and Director of the Sustainable Transportation Energy Pathways Program at the campus s Institute of Transportation Studies. Her primary research interest is the technical and economic assessment of new energy technologies, especially in the areas of alternative fuels, fuel cells, renewable energy and low carbon energy systems. She received a B.S. in Mathematics from the University of Illinois, and a Ph.D. in Physics from the University of Maryland.

Lactic acid, as well as being a component of the NMF, is also a member of the class of molecules called alpha hydroxy acids (AHAs), which exert specific and unique benefits on skin structure and function. Although originally described for the treatment of dry skin-related disorders, their pleiotropic properties include influencing skin cell renewal and other antiaging benefits, which have become the focus of considerable interest in recent years.

Calcium is important for several functions in the body, including bone and teeth growth, function of nerves and muscles, proper heart function and blood clotting [11]. Likewise, Mg is needed for protein and fatty acid formation, cell renewal,... 

There are two characteristics that distinguish stem cells from other types of cells stem cells can self renew, and they can differentiate into other types of cells. Stem cells renew themselves for long periods through cell division, and given certain conditions, they can be induced to become cells with special functions. 

Paneth cells contribute to the maintenance of the gastrointestinal barrier, by secreting a number of antimicrobial molecules (alpha-defensins or cryptidins), as well as lysozyme and phospholipase A2. Their location, adjacent to crypt stem cells, suggests they have a role in defending epithelial cell renewal.

In the first year after treatment 20% of patients will become hypothyroid. After this 5% of patients become hypothyroid annually, perhaps because the capacity of thyroid cells to divide is permanently abolished so that cell renewal ceases. Patients must therefore be foUowed up indefinitely after radioiodine treatment, for most are likely to need treatment for hypothyroidism eventually. Because such followup over years may fail and because the onset of hypothyroidism may be insidious and not easily recongnised, some physicians prefer deliberately to render patients hypothyroid with the first dose and to educate them on the use of replacement therapy which is safe and effective. 

Concentrations of lactic acid of 10-20% or stronger begin to destroy the stratum corneum and stimulate skin regeneration, the renewal of epidermal cells. However, some studies have shown that cell renewal is not maintained uniformly during long-term treatments with 3% lactic acid... 

Stem cell renewal and differentiation occur within the bone marrow under the influence of the marrow microenvironment. Stromal endothelial cells, fibroblasts, and fat cells (adipocytes) are necessary to support stem cell proliferation and division by providing anchorage for adhesion and secreting various hematopoietic growth factors necessary for differentiation. It is the characteristics of the local microenvironment (cellular matrix and growth factor concentrations) that influence the differentiation of a particular hematopoietic lineage, favoring it over another. 

Further work by Wynberg and coworkers was aimed at even increasing the yield of 1,2-epoxyoctane using an optimized two-phase system and a cell renewal procedure11191. Thus, yields up to 150 mg 1,2-epoxyoctane per mL 1-octene and up to 20-25 mg 1,2-epoxyoctane per mL culture was obtained. Some other substrates were tested in this optimized system. Of these, 1-decene was converted into (R)-l,2-epox-ydecane (60 % o. p.), while allylbenzene was converted to the corresponding epoxide. However, no effort was made to determine the absolute configuration and the optical purity of this product.
