H2S‐Amplified “Three‐in‐One” Antibacterial Strategy for Periodontitis Treatment Using a Photosensitive Pillararene‐Embedded COF/MOF Hybrid

Advanced Science, EarlyView.
The integration of ROS‐generating systems with H2S depletion strategies effectively overcomes the limitations imposed by endogenous antioxidant defenses on ROS‐based antimicrobial therapies. In this study, the Cu‐MOF is incorporated into pillararene‐embedded COF, achieving a “three‐in‐one” antimicrobial effect that markedly alleviated periodontal ...

The association between medication use and vitamin B12 deficiency in the elderly population: a cross- sectional study

BMC Geriatrics
Background Vitamin B12 deficiency is common in the elderly population and can cause severe complications. The use of certain medication has in previous studies been associated with vitamin B12 deficiency in the general population.

m.10010T>C Mitochondrial Disease: A Case Report With Hypoparathyroidism and Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Mitochondria are essential intracellular organelles that play a critical role in cellular metabolism, including the regulation of intracellular calcium signaling. Advances in genomic sequencing have facilitated the identification of rare pathogenic mitochondrial DNA (mtDNA) genetic variants in patients with unexplained endocrine disorders.

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

Vitamin B12 and progression of white matter lesions. A 2-year follow-up study in first-ever lacunar stroke patients. [PDF]

PLoS ONE, 2013
In cross-sectional studies periventricular white matter lesions (WML) were related to low plasma levels of vitamin B12. Whether low vitamin B12 levels are also related to progression of WML is still unknown. We studied baseline vitamin B12 levels and its

Utilization of cognitive support in episodic free recall as a function of apolipoprotein E and vitamin B12 or folate among adults aged 75 years and older [PDF]

, 2004
Apolipoprotein E (APOE), vitamin B12, and folate were examined in relation to free recall among 167 community-based older adults. Cognitive support at encoding and retrieval was also taken into account.

Enantioselective Alkylation of Hydrophobic Vitamin B12 Bearing a Binaphthyl Moiety [PDF]

, 1992
The enantioselective alkylation of hydrophobia vitamin B12 derivatives at the β-axial site was examined in methanol with various alkyl bromides, and those B12 analogues bearing a peripheral binaphthyl moiety showed the highest S-selectivity toward ...
