Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...

Synthesis of Naphthoquinones by Pd‐Catalyzed Heck–Matsuda Arylation of Lapachol

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Direct Heck–Matsuda arylation of lapachol enables the efficient synthesis of diverse naphthoquinones under homogeneous and heterogeneous palladium catalysis. The methodology features broad substrate scope, gram‐scale applicability, and provides a practical platform for quinone diversification.

Proteomic signatures of equine dental tooth tissues in ageing and disease

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Amyloid‐β–Related Cortical Susceptibility Alterations in Individuals Under Assessment for Alzheimer's Disease: A χ‐Separation Study

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Assessment of amyloid‐β (Aβ) burden and associated iron deposition and neurodegeneration is important for Alzheimer's disease (AD) management. Although quantitative susceptibility mapping (QSM) detects iron and myelin changes, conventional metrics suffer from signal cancelation between paramagnetic and diamagnetic components ...

Preserved anterolateral ligament graft continuity on MRI and lower knee laxity after ACL graft failure than before index combined ACL–ALL reconstruction: A retrospective case series

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate magnetic resonance imaging (MRI)‐based continuity and signal characteristics of reconstructed anterolateral ligament (ALL) grafts and compare anteroposterior and rotational knee laxity after anterior cruciate ligament (ACL) graft failure with values recorded before the index combined ACL–ALL reconstruction.

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Perceptual defensiveness and ESP performance: Reconstructed DMT ratings and psychological correlates in the first German DMT-ESP experiment

open access: yes, 2002
The concept of perceptual defensiveness is related to subliminal perception and preconscious processing. Meta-analyses of earlier experiments, 6 in the United States and Holland and 10 in Iceland, on the Defense Mechanism Test (DMT)-ESP relationship had ...
