Elevated Levels of Methylmalonate and Homocysteine in Parkinson's Disease, Progressive Supranuclear Palsy and Amyotrophic Lateral Sclerosis [PDF]

, 2010
Background/Aims: Increasing evidence suggests that elevated levels of homocysteine (Hcy) and methylmalonate (MMA) may be involved in the pathogenesis of neurodegenerative diseases. Methods: The urine levels of MMA and serum levels of Hcy as well as folic

The influence of ultra‐processed foods on gut microbiome and inflammatory markers in schoolchildren from Northeastern Brazil

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objective This study investigated the relationship between the consumption of ultra‐processed foods (UPF), dietary profile, and inflammation on the intestinal microbiome in children. Methods A cross‐sectional study was conducted using data from a community‐based controlled trial involving 82 children aged 7–11 years enrolled in public schools ...

The relationship between exacerbated diabetic peripheral neuropathy and metformin treatment in type 2 diabetes mellitus

Scientific Reports, 2021
Metformin-treated diabetics (MTD) showed a decrease in cobalamin, a rise in homocysteine, and methylmalonic acid, leading to accentuated diabetic peripheral neuropathy (DPN). This study aimed to determine whether or not metformin is a risk factor for DPN.

Receptor uptake arrays for vitamin B12, siderophores and glycans shape bacterial communities

, 2017
Molecular variants of vitamin B12, siderophores and glycans occur. To take up variant forms, bacteria may express an array of receptors. The gut microbe Bacteroides thetaiotaomicron has three different receptors to take up variants of vitamin B12 and 88 ...

Nutrient cross-feeding in the microbial world. [PDF]

, 2014
The stability and function of a microbial community depends on nutritional interactions among community members such as the cross-feeding of essential small molecules synthesized by a subset of the population.

The X‐Ray Crystal Structure of BorF, the Flavin Reductase Subunit of a Two‐Component Flavin‐Dependent Tryptophan Halogenase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

Resistance imparted by vitamin C, vitamin e and vitamin B12 to the acute hepatic glycogen change in rats caused by noise. [PDF]

, 2006
The effects of vitamin C, vitamin E and vitamin B12 on the noise-induced acute change in hepatic glycogen content in rats were investigated. The exposure of rats to 95 dB and 110 dB of noise acutely reduced their hepatic glycogens.

Hcfc1 and Ogt Mediate Zebrafish CNS Regeneration Through Hippo/Yap Signalling

Cell Proliferation, EarlyView.
This work identifies Hcfc1 and Ogt as key regulators of zebrafish CNS regeneration through modulation of Hippo/Yap signalling. Loss of Hcfc1 or Ogt activity inhibition impairs regeneration, which is restored by Yap overexpression, revealing a new regulatory axis that enhances CNS regenerative capacity.

FAD binding, cobinamide binding and active site communication in the corrin reductase (CobR) [PDF]

, 2014
Adenosylcobalamin, the coenzyme form of vitamin B12, is one Nature's most complex coenzyme whose de novo biogenesis proceeds along either an anaerobic or aerobic metabolic pathway. The aerobic synthesis involves reduction of the centrally chelated cobalt
