Serum vitamin B12 associated with vitamin D/25(OH)D in women with recurrent aphthous stomatitis.
Journal of Oral Research, 2020 Vitamin B12 and Vitamin D deficiency may contribute to recurrent aphthous stomatitis (RAS). Current studies have showed vitamin B12 to be associated with vitamin D in women, however no study has assessed vitamin B12 associated with vitamin D/25(OH)D in ...

Receptor uptake arrays for vitamin B12, siderophores and glycans shape bacterial communities [PDF]
Ecology & Evolution 7:10175-10195 (2017), 2017 Molecular variants of vitamin B12, siderophores and glycans occur. To take up variant forms, bacteria may express an array of receptors. The gut microbe Bacteroides thetaiotaomicron has three different receptors to take up variants of vitamin B12 and 88 receptors to take up various glycans.

Low vitamin B12 levels among newly-arrived refugees from Bhutan, Iran and Afghanistan: a multicentre Australian study. [PDF]
PLoS ONE, 2013 BACKGROUND: Vitamin B12 deficiency is prevalent in many countries of origin of refugees. Using a threshold of 5% above which a prevalence of low Vitamin B12 is indicative of a population health problem, we hypothesised that Vitamin B12 deficiency exceeds

Electronically Excited States of Vitamin B12: Benchmark Calculations Including Time-Dependent Density Functional Theory and Correlated Ab Initio Methods [PDF]
Journal of Physical Chemistry A, 115, 1280 (2011), 2011 Time-dependent density functional theory (TD-DFT) and correlated ab initio methods have been applied to the electronically excited states of vitamin B12 (cyanocobalamin or CNCbl). Different experimental techniques have been used to probe the excited states of CNCbl, revealing many issues that remain poorly understood from an electronic structure point ...

Vitamin B12 Deficiency Alters the Gut Microbiota in a Murine Model of Colitis
Frontiers in Nutrition, 2020 Purpose: Inflammatory bowel disease (IBD) refers to a spectrum of autoimmune diseases, which result in chronic intestinal inflammation. Previous findings suggest a role for diet, nutrition and dysbiosis of the gut microbiota in both the development and ...

, 2018 The biosynthesis of B12, involving up to 30 different enzyme-mediated steps, only occurs in bacteria. Thus, most eukaryotes require an external source of B12, and yet the vitamin appears to have only two functions in eukaryotes: as a cofactor for the enzymes methionine synthase and methylmalonylCoA mutase.
