Zinc Supplementation Does Not Alter Indicators of Insulin Secretion and Sensitivity in Black and White Female Adolescents [Nutrition and Disease]

Zinc Supplementation Does Not Alter Indicators of Insulin Secretion and Sensitivity in Black and White Female Adolescents [Nutrition and Disease] Background: Zinc is a micronutrient involved in the production of, and peripheral sensitivity to, pancreatic β cell–derived insulin. To our knowledge, the effect of zinc supplementation on insulin outcomes, and potential risk of diabetes, in…

Intragastric Lysine Lowers the Circulating Glucose and Insulin Responses to a Mixed-Nutrient Drink without Slowing Gastric Emptying in Healthy Adults [Nutrient Physiology, Metabolism, and Nutrient-Nutrient Interactions]

Intragastric Lysine Lowers the Circulating Glucose and Insulin Responses to a Mixed-Nutrient Drink without Slowing Gastric Emptying in Healthy Adults [Nutrient Physiology, Metabolism, and Nutrient-Nutrient Interactions] Background: Lysine is reported to lower the glycemic response to oral glucose in humans and, albeit at high loads, to slow gastric emptying of glucose and decrease food intake…

Iron, Zinc, Folate, and Vitamin B-12 Status Increased among Women and Children in Yaounde and Douala, Cameroon, 1 Year after Introducing Fortified Wheat Flour [Community and International Nutrition] Background: Few data are available on the effectiveness of large-scale food fortification programs. Objective: We assessed the impact of mandatory wheat flour fortification on micronutrient status in…

Biotin: From Nutrition to Therapeutics [Recent Advances in Nutritional Sciences]

Biotin: From Nutrition to Therapeutics [Recent Advances in Nutritional Sciences] Although frank symptomatic biotin deficiency is rare, some evidence suggests that marginal biotin deficiency occurs spontaneously in a substantial proportion of women during normal human pregnancy and might confer an increased risk of birth defects. Herein I review 1) advances in assessing biotin status, including…

Vitamin C induces specific demethylation of H3K9me2 in mouse embryonic stem cells via Kdm3a/b

Vitamin C induces specific demethylation of H3K9me2 in mouse embryonic stem cells via Kdm3a/b Histone methylation patterns regulate gene expression and are highly dynamic during development. The erasure of histone methylation is carried out by histone demethylase enzymes. We had previously shown that v… Vitamin C induces specific demethylation of H3K9me2 in mouse embryonic stem…
