A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

The FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

The FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Effects of Bleaching Protocols on the Esthetic Outcome and Surface Integrity of Enamel Treated With an Ammonia‐Free Silver Fluoride Solution

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To investigate the effects of three bleaching protocols on the color stability and surface roughness of enamel previously treated with a water‐based, ammonia‐free silver fluoride solution (Riva Star Aqua). Materials and Methods Eighty‐eight human enamel/dentin specimens were demineralized and treated with Riva Star Aqua, divided into

Effect of Cigarette Smoking on the Surface Roughness, Color, and Translucency of Zirconia Produced by Additive and Subtractive Manufacturing

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To compare the surface roughness, color stability, and translucency of zirconia produced by additive manufacturing (AM) and subtractive manufacturing (SM) after exposure to cigarette smoking. Materials and Methods A total of 60 disc‐shaped specimens were fabricated from 2 methods: AM (INNI Cera BCM W500/1000) and SM (VITA YZ T).

High‐throughput multispecies quantitative polymerase chain reaction assays to study the effects of acute thermal stress in three species of Acipenser sturgeon

Journal of Fish Biology, EarlyView.
Abstract Fishes experience thermal stress in their natural environment that can be caused by natural or anthropogenic factors and can directly affect their physiology. In this study, we developed a multispecies OpenArray™ qPCR (quantitative polymerase chain reaction) ‘chip’ to measure the effects of acute thermal stress on the mRNA response of ...

Innovative Field Applications of Probiotics, Prebiotics, and Medicinal Plant Products for Disease Control in Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Disease outbreaks and the associated reliance on antibiotics pose major constraints to the sustainability of modern aquaculture. As regulatory pressures increase and consumer demand shifts toward residue‐free production, diverse biological interventions are gaining prominence as viable alternatives to chemotherapeutics.
