Detection of Testosterone Esters in Urine: Evidence of Trace‐Level Detectability in Doping Control Samples

Drug Testing and Analysis, EarlyView.
An ultrasensitive LC‐MS/MS method for detecting testosterone esters (T‐esters) in urine at sub–pg/mL levels is presented. This approach, employing Girard P derivatization, provides the first evidence of T‐esters' trace‐level detectability in human urine.

Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Loss of POGLUT2/3‐mediated O‐glucosylation produces lung and aortic phenotypes reminiscent of fibrillin1 mutants

Developmental Dynamics, EarlyView.
Abstract Background Fibrillins provide a scaffold for elastic fiber formation, which enables lung recoil and aortic compliance. Abnormal fibrillin microfibrils, as in Marfan syndrome, lead to enlarged alveoli, vascular stiffening, and aneurysms. Our earlier studies suggested that fibrillin function depends on O‐glucosylation of its epidermal growth ...

Lattice‐Strained Cu2O‐Ni/NiO Heterostructure Enables Selective Electrocatalytic C–C Coupling of Alcohols to Cinnamaldehyde in Aqueous Medium

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved the selective oxidation C–C coupling of PhCH2OH with EtOH to form cinnamaldehyde (CAL) on a designed Cu2O‐Ni/NiO heterojunction catalyst. By employing a salt precipitation strategy to balance the pH and cation concentration, an 86% conversion rate of PhCH2OH and a 67% high selectivity for CAL were realized.

Bidentate‐Ligand Molecular Bridge in NiFe‐LDH as a Dynamic Proton Relay and Electronic Modulator to Enhance the Oxygen Evolution Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
By introducing 4‐chlorobenzoic acid ligands into the interlayer of NiFe‐LDH, the carboxyl and Cl groups on either side are respectively bonded to nearby Fe atoms, yielding a stable Bridge‐Linked structure. The strong electron interaction between the ligands and metal ions suppresses metal ion leaching during the reaction process, thereby maintaining ...

Increased calcification by erythrophagocytosis in aortic valvular interstitial cells

ESC Heart Failure, Volume 12, Issue 2, Page 1469-1473, April 2025.
Abstract Background Calcific aortic valve disease (CAVD) progresses over time to severe aortic stenosis and eventually heart failure. Recent evidence indicates that intraleaflet haemorrhage (ILH) strongly promotes CAVD progression. However, it remains poorly understood how it mechanistically contributes to valvular calcification.
