A cross‐sectional clinical study in women to investigate possible genotoxicity and hematological abnormalities related to the use of black cohosh botanical dietary supplements

Environmental and Molecular Mutagenesis, Volume 63, Issue 8-9, Page 389-399, December 2022., 2022
Abstract Black cohosh (BC; Actaea racemosa L.), a top‐selling botanical dietary supplement, is marketed to women primarily to ameliorate a variety of gynecological symptoms. Due to widespread usage, limited safety information, and sporadic reports of hepatotoxicity, the Division of the National Toxicology Program (DNTP) initially evaluated BC extract ...

Interspecies transfer of biosynthetic cobalamin for complete dechlorination of trichloroethene by Dehalococcoides mccartyi

Water Science and Technology, 2022
Complete dechlorination of trichloroethene (TCE) by Dehalococcoides mccartyi is catalyzed by reductive dehalogenases (RDases), which possess cobalamin as the crucial cofactor. However, virtually all D. mccartyi isolated thus far are corrinoid auxotrophs.

Cobalamins and cobalamin-dependent enzymes in Candida utilis [PDF]

Journal of Bacteriology, 1979
Candida utilis has been shown to contain 4.7 pmol of cobalamin per g of wet cell paste. Purification of the cobalamin showed it to be a mixture of methylcobalamin and adenosylcobalamin. Two cobalamin-dependent enzyme systems have been found in the yeast: methylcobalamin-dependent methionine biosynthesis and leucine 2,3-aminomutase.

COBALAMIN DEFICIENCY IN THE ELDERLY

Mediterranean Journal of Hematology and Infectious Diseases, 2020
Older people are at risk for cobalamin (vitamin B12) deficiency because of a number of common disorders (e.g. autoimmune gastritis) and drugs (e.g. antacids) that may alter its absorption and utilization. The prevalence of cobalamin deficiency increases with age, resulting particularly elevated in frail and institutionalized subjects.

Impact of dietary supplementation of unsaturated and saturated fatty acids on bone strength, fatty acids profile of thigh muscle and immune responses in broiler chickens under heat stress

Veterinary Medicine and Science, Volume 9, Issue 1, Page 252-262, January 2023., 2023
Results suggest that there is not beneficial effect of broiler performance due to adding different source of fat in broiler chicken diet under hot condition. Furthermore, the unsaturated fatty acids could improve profile of fatty acids in thigh and enhance immune responses in broiler chickens.

The Intestinal Microbiome in Dogs with Chronic Enteropathies and Cobalamin Deficiency or Normocobalaminemia—A Comparative Study

Animals, 2023
Cobalamin deficiency is a common sequela of chronic enteropathies (CE) in dogs. Studies comparing the intestinal microbiome of CE dogs with cobalamin deficiency to those that are normocobalaminemic are lacking.

The effect of acidifier supplementation on egg production performance and intestinal histology of Japanese quail (Coturnix japonica)

Veterinary Medicine and Science, Volume 9, Issue 1, Page 263-271, January 2023., 2023
This study aimed to investigate the effect of dietary supplementation of a commercial acidifier on egg production and histology of small intestine in laying Japanese quail. Our results indicate that supplementation of 1 and 2.6 g acidifier per kg of diet was associated with beneficial effects on egg production and quality, GIT pH and histology of small

The cobalamin-binding protein in zebrafish is an intermediate between the three cobalamin-binding proteins in human.

PLoS ONE, 2012
In humans, three soluble extracellular cobalamin-binding proteins; transcobalamin (TC), intrinsic factor (IF), and haptocorrin (HC), are involved in the uptake and transport of cobalamin.

Production of diverse brGDGTs by Acidobacterium Solibacter usitatus in response to temperature, pH, and O2 provides a culturing perspective on brGDGT proxies and biosynthesis

Geobiology, Volume 21, Issue 1, Page 102-118, January 2023., 2023
Abstract Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are bacterial membrane lipids that are frequently employed as paleoenvironmental proxies because of the strong empirical correlations between their relative abundances and environmental temperature and pH.

Effect of oral or injectable supplementation with cobalamin in dogs with hypocobalaminemia caused by chronic enteropathy or exocrine pancreatic insufficiency

Journal of Veterinary Internal Medicine, 2022
Background Recent studies have shown similar efficacy of oral supplementation of cobalamin compared to injectable supplementation in dogs, but few prospective, randomized studies have been published.
