Associations Between Nicotine Metabolites and Serum Neurofilament Light Chain Levels in the General Population

Chronic Diseases and Translational Medicine, EarlyView.
ABSTRACT Background Nicotine has been associated with cognitive functions such as memory and attention, with serum neurofilament light chain (sNfL) as a biomarker for neurological diseases such as Alzheimer's disease (AD) and multiple sclerosis (MS).

Milligram‐Scale Enzymatic Synthesis of Base‐Modified DNA through Primer Extension: Polymerase Synthesis and NMR Structures of DNA Containing Phenyl‐Substituted Nucleobases

ChemistryEurope, EarlyView.
Larger‐scale enzymatic synthesis of base‐modified DNA is developed using primer extension with KOD(exo‐) DNA polymerase allowing preparation of milligram amounts of the modified DNA sufficient for NMR structural analysis. Milligram (≈200 nmol) scale enzymatic synthesis of base‐modified DNA is developed based on primer extension using easily accessible ...

Photocatalytic Degradation of PFOA with Porous Lanthanoid Perovskites Nano Catalyst

Chemie Ingenieur Technik, EarlyView.
Photocatalytic degradation of PFOA was studied using nickel‐ and lanthanide‐doped perovskites under UV–VIS irradiation. Catalyst characterization confirmed successful doping, with Ni/NdMnO3 showing the highest photocatalytic efficiency. Degradation occurred via C–C bond cleavage, forming transformation products PFHpA and PFHxA.
