Vegan diet and nutritional status in infants, children and adolescents: A position paper based on a systematic search by the ESPGHAN Nutrition Committee

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Vegan and other plant‐based diets are becoming increasingly popular in the paediatric age group. There is limited evidence in the current medical literature to determine whether a vegan diet is adequate for children, since the currently available society position papers are based on narrative reviews and expert opinion.

A low oxygen threshold for physiological responses and trace metal quotas of Prochlorococcus and Synechococcus

Limnology and Oceanography, EarlyView.
Abstract Continued human activity is expected to accelerate ocean deoxygenation, leading to the expansion and shallowing of oxygen‐deficient zones (ODZs). This decline in oxygen may impact both phytoplankton growth and trace metal uptake. We conducted culture experiments with Prochlorococcus MIT9313 and Synechococcus XM‐24, two numerically dominant ...

An ecological framework for microbial metabolites in the ocean ecosystem

Limnology and Oceanography Letters, EarlyView.
Abstract The ocean microbe‐metabolite network involves thousands of individual metabolites that encompass a breadth of chemical diversity and biological functions. These microbial metabolites mediate biogeochemical cycles, facilitate ecological relationships, and impact ecosystem health. While analytical advancements have begun to illuminate such roles,

Refining Knowledge of Factors Affecting Vitamin B₁₂ Concentration in Bovine Milk

Animals, 2021
Milk is an excellent source of vitamin B12 (B12) for humans. Therefore, being able to guarantee a high and consistent concentration of this vitamin would enhance consumer perception of milk as a health food.

On the Effect of Ionizing Radiations on Cyanocobalamin. [PDF]

Acta Chemica Scandinavica, 1959
Solutions of cyanocobalamin in a phosphate buffer of pH 5 were irradiated with doses of 2, 5, and 10 Mrad. Concomitant with a decrease in absorption maxima following irradiation was a tendency for the peaks in the 360 to 550 m mu regions to shift towards lower wave-lentihs. Calculattons indicated that 60% of the vitamin originally present was destroyed

Nutritional Deficiencies Following Bariatric Surgery: A Rapid Systematic Review of Case Reports of Vitamin and Micronutrient Deficiencies Presenting More Than Two Years Post‐Surgery

Clinical Obesity, EarlyView.
ABSTRACT Bariatric surgery is the most clinically‐ and cost‐effective intervention for severe obesity. However, without adequate follow‐up, it can lead to nutritional deficiencies. Patients require life‐long nutritional supplements and follow‐up to prevent nutritional deficiencies from developing.
