Vitamin B-12 deficiency stimulates osteoclastogenesis via increased homocysteine and methylmalonic acid [PDF]

, 2009
The risk of nutrient deficiencies increases with age in our modern Western society, and vitamin B(12) deficiency is especially prevalent in the elderly and causes increased homocysteine (Hcy) and methylmalonic acid (MMA) levels.

Programming Gut Microbiome Function Through Cross‐Feeding: From Ecological Mechanisms to Live Biotherapeutics

Advanced Science, EarlyView.
This graphical abstract presents gut microbial cross‐feeding through a Mechanism–Technology–Application framework. It summarizes major resource‐transfer modes, the experimental and computational tools used to establish causality, and potential interventions involving dietary substrates, live biotherapeutic products, and engineered microbes.

ADNP‐Related Helsmoortel–Van der Aa Syndrome: A Review of the Literature and Clinical Recommendations for Assessment and Monitoring

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT ADNP‐related Helsmoortel–Van der Aa syndrome (ADNP‐related HVDAS) is a single gene form of autism spectrum disorder (ASD) caused by pathogenic sequence variants in the activity‐dependent neuroprotective protein (ADNP) gene. In addition to ASD, ADNP‐related HVDAS is associated with a wide range of cognitive, behavioral, and physical health ...

Trace Elements Genetics: A Potential Role in Treatment‐Resistant Major Psychoses and Related Traits?

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Trace elements are pivotal to key biological processes, with possible effects on psychopathology. We investigated the hypothesis of shared genetic factors between trace elements levels, treatment resistance and related traits. We used genome‐wide summary statistics for trace elements blood concentration, treatment‐resistant depression (TRD ...

The effect of recombinant human intrinsic factor on the uptake of vitamin B12 in patients with evident vitamin B12 deficiency

Haematologica, 2006
We report on the use of recombinant human intrinsic factor (rhIF) in a new vitamin B12 absorption test. Holotranscobalamin (holoTC) was measured before and 24 hours after intake of three 9-mg doses of vitamin B12 (B12) and again 24 hours after intake of ...

Dietary Mannan‐Rich Fractions Attenuate Weaning Stress in Piglets via Modulating Gut Microbiota and TLR5/NF‐κB Signaling

Animal Research and One Health, EarlyView.
This study aimed to investigate the potential of a mannan‐rich fraction (MRF) as a dietary intervention to alleviate weaning stress in piglets. Our results revealed that MRF could alleviate weaning stress by modulating the gut microbiota and the TLR5/NF‐κB signaling pathway, offering a novel and sustainable alternative to antibiotic use in swine ...

Correlations between the Composition of the Bovine Microbiota and Vitamin B₁₂ Abundance

mSystems, 2020
Vitamin B12 is synthesized by prokaryotes in the rumens of dairy cows—and this has implications in human nutrition since humans rely on consumption of dairy products for vitamin B12 acquisition. However, the concentration of vitamin B12 in milk is highly
