Cobalamin Protection against Oxidative Stress in the Acidophilic Iron-oxidizing Bacterium Leptospirillum group II CF-1

Frontiers in Microbiology, 2016
Members of the genus Leptospirillum are aerobic iron-oxidizing bacteria belonging to the phylum Nitrospira. They are important members of microbial communities that catalyze the biomining of sulfidic ores, thereby solubilizing metal ions.

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, Volume 15, Issue 6, December 2025.
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.

A cobalt concentration sensitive Btu-like system facilitates cobalamin uptake in Anabaena sp. PCC 7120

Microbial Cell
Metal homeostasis is central to all forms of life, as metals are es-sential micronutrients with toxic effects at elevated levels. Macromolecular machines facilitate metal uptake into the cells and their intracellular level is regulated by multiple means,

Treatment of Feline Lymphocytic Lymphoma/Chronic Inflammatory Enteropathy Complex With Low Dose Abdominal Cavity Radiation Therapy

Veterinary and Comparative Oncology, Volume 23, Issue 4, Page 549-557, December 2025.
ABSTRACT The goal of this prospective, single‐arm pilot study was to assess tolerability and clinical benefit for cats with histologically confirmed lymphocytic lymphoma/chronic inflammatory enteropathy complex (FLL/CIE) treated with low‐dose abdominal cavity radiation therapy (RT; 8 Gy total dose administered in four 2 Gy fractions).

B12‐Cofactor Inactivation by Cobalt to Rhodium Mutation in Methylrhodibalamin: An Antivitamin B12 and Antibiotic

ChemistryEurope, Volume 3, Issue 6, November 11, 2025.
Replacement of cobalt in the organometallic B12‐cofactor methylcobalamin (MeCbl) by rhodium furnishes a structural mimic with a significantly stronger metal–carbon bond. This synthetically challenging formal metal‐mutation converts the naturally optimized biological methyl‐transfer catalyst MeCbl into a designed antivitamin B12, an inactivated B12 ...
