Methanotrophic Flexibility of ‘Ca. Methanoperedens’ and Its Interactions With Sulphate‐Reducing Bacteria in the Sediment of Meromictic Lake Cadagno

Environmental Microbiology, Volume 27, Issue 7, July 2025.
In anoxic sediments of the meromictic freshwater Lake Cadagno ‘Ca. Methanoperedens’ and sulphate‐reducing Desulfobacterota QYQD01 co‐occur. Metagenomics revealed that ‘Ca. Methanoperedens’ genomes harbour different extracellular electron transfer pathways.

Exploring Early Childhood Development Interventions for Building Human Capital in Sub‐Saharan Africa: A Scoping Review

Child: Care, Health and Development, Volume 51, Issue 4, July 2025.
ABSTRACT Background Inequalities in the provision and implementation of early childhood development (ECD) interventions in Sub‐Saharan Africa remain a challenge. This scoping review aimed to investigate the types and extent of ECD interventions in this region, using the Nurturing Care framework (NCF).

Characterization and ex vivo modelling of endodontic infections from the Arabian Gulf region

International Endodontic Journal, Volume 58, Issue 7, Page 1091-1108, July 2025.
Abstract Aim The microbiota of endodontic infections in patients from the Arabian Gulf region (AGR) is largely unexplored. While research in different global regions has investigated the microbial composition of such infections, studies using shotgun metagenomic sequencing (SMS) alongside culture‐dependent techniques (CDT) are limited.

Improving the diagnosis of cobalamin and related defects by genomic analysis, plus functional and structural assessment of novel variants

Orphanet Journal of Rare Diseases, 2018
Background Cellular cobalamin defects are a locus and allelic heterogeneous disorder. The gold standard for coming to genetic diagnoses of cobalamin defects has for some time been gene-by-gene Sanger sequencing of individual DNA fragments.

Nutritional Intake and Status of Cobalamin and Folate among Non-Pregnant Women of Reproductive Age in Bhaktapur, Nepal

Nutrients, 2016
Cobalamin and folate are especially important for women of childbearing age due to their ubiquitous role in fetal growth and development. Population-based data on cobalamin and folate status are lacking from Nepal, where diets are mostly vegetarian.

Cobalamin, the stomach, and aging [PDF]

The American Journal of Clinical Nutrition, 1997
Low cobalamin concentrations are common in the elderly. Although only a minority of such persons display clinically obvious symptoms or signs, metabolic data clearly show cellular deficiency of cobalamin in most cases. The evidence suggests that this is not a normal physiologic expression of the aging process. Rather, the elderly seem at increased risk
