Dextran has yet to be approved for any clinical uses in drug delivery due to a wide variety of limitations including heterogeneity, undesirable side effects, and unknown biological pathways. Changes in the molecular weight of dextran have been shown to alter biological activity, indicating a need for separation and purification processes to ...
An uncommon but significant complication of dextran osmotic effect is acute kidney injury. [15] The pathogenesis of this kidney failure is the subject of many debates with direct toxic effect on tubules and glomerulus versus intraluminal hyperviscosity being some of the proposed mechanisms.
Dextran sulphate sodium (DSS), or dextran sodium sulphate (or any of the former with "sulfate") is a synthetic sulphated polysaccharide with anticoagulant activity used in immunological research to induce colitis. [1] [2] Dextran polymer molecules with a molecular weight of 36–50 kDa are frequently used to this end. [2]

Allene Rosalind Jeanes (July 19, 1906 – December 11, 1995) was an American chemist whose pioneering work significantly impacted carbohydrate chemistry. Born in 1906 in Texas, Jeanes' notable contributions include the development of Dextran, a lifesaving blood plasma substitute used in the Korean and Vietnam wars, and Xanthan gum, a polysaccharide commonly used in the food, cosmetics, and ...
A Long Island livestock sanctuary faces 112 counts of animal neglect for allegedly depriving dozens of animals of food, water, and shelter, according to prosecutors. Investigators visited Double D ...
S. mutans uses the enzyme glucansucrase to convert sucrose into a sticky, extracellular, dextran-based polysaccharide that allows them to cohere, forming plaque. S. mutans produces dextran via the enzyme dextransucrase (a hexosyltransferase) using sucrose as a substrate in the following reaction: n sucrose → (glucose) n + n fructose
