Nicotinamide (Vitamin B3) Deficiency in Follicular Fluid of Patients With Ovarian Ageing
ABSTRACT Nicotinamide is an essential precursor of NAD involved in energy metabolism. A decline in NAD levels across tissues during ageing is well‐documented, and NAD metabolism has been implicated in ovarian ageing. We investigated the relationship between ovarian ageing and the levels of nicotinamide (NAM) and its metabolite 1‐methylnicotinamide (MNA)

Timing of NAD Deficiency During Organogenesis Dictates Defect Type and Penetrance
Pregnant mice on a vitamin B3‐free and tryptophan‐limited diet have embryos with Congenital NAD Deficiency Disorder, characterized by malformations and/or death. We longitudinally tracked the maternal NAD metabolome, embryo growth, and malformation occurrence. Mice with lower NAD Salvage Pathway metabolite levels and minimal levels of derived excretion

This study introduces two new fluorine‐free ionic liquids (ILs) produced by coupling biomass‐derived heterocyclic anions, i.e., THP and 3‐FuA, with P4444 cation. Both the ILs display enhanced capacitance with increasing temperature, underscoring their potential as fluorine‐free electrolytes for supercapacitors.
