Journal of Periodontal Research, EarlyView.Metabolomic fingerprints analyzed from oral rinses are able to distinguish between severe periodontitis (stage III/IV) patients and non‐periodontitis controls. ABSTRACT Aims To explore the potential of metabolomic profiles of oral rinse samples to distinguish between patients with severe periodontitis (stage III/IV) and non‐periodontitis controls. This

Vitamin B12 in Cats: Nutrition, Metabolism, and Disease
Animals, 2023 Cobalamin is a water-soluble molecule that has an important role in cellular metabolism, especially in DNA synthesis, methylation, and mitochondrial metabolism. Cobalamin is bound by intrinsic factor (IF) and absorbed in the ileal tract.

How do we evaluate a marginally low B12 level? [PDF]
, 2007 The best way to evaluate a low-normal B12 level is to check serum methylmalonic acid and homocysteine levels1 (strength of recommendation [SOR]: B, based on consistent level 2 or 3 studies).

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges
Experimental Physiology, EarlyView.Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.

Natural History and Diagnostic Findings in an Adult Man Diagnosed With Attenuated Krabbe Disease
American Journal of Medical Genetics Part A, Volume 197, Issue 7, July 2025.ABSTRACT Krabbe disease (KD), or globoid cell leukodystrophy, is a rare autosomal recessive lysosomal storage disorder caused by a deficiency in galactocerebrosidase (GALC), leading to psychosine (galactosylsphingosine) accumulation and myelin damage.

Metabolic phenotype of methylmalonic acidemia in mice and humans: the role of skeletal muscle
BMC Medical Genetics, 2007 Background Mutations in methylmalonyl-CoA mutase cause methylmalonic acidemia, a common organic aciduria. Current treatment regimens rely on dietary management and, in severely affected patients, liver or combined liver-kidney transplantation.

A Technique for Measurement of Methylmalonic Acid in Cattle Urine
Journal of Dairy Science, 1977 Methylmalonic acid was measured in cattle urine by decarboxylating it to propionate with sulfuric acid and heat and quantifying the propionate so formed by gas-liquid chromatography. Crystalline methylmalonic acid added to cow urine was recovered quantitatively.
