Controlled Atom Transfer Radical Depolymerization

open access: yesAdvanced Science, EarlyView.
Controlled atom transfer radical depolymerization allows for precise, uniform shortening of polymer chains to yield monomers on demand. By tuning catalyst concentration and temperature, this strategy prioritizes deactivation to maintain molecular weight control throughout depolymerization.

PREVALENCE, LOCATION, AND MORPHOLOGY OF MAXILLARY SINUS SEPTA IN A UNITED STATES PATIENT POPULATION [PDF]

open access: yes, 2017
Objectives: The presence of sinus septa may cause complications in maxillary sinus elevation surgery such as perforations. CBCT is important for planning the size, shape, and position of the sinus septa, and help separation of the sinus membrane from the

A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

open access: yesAdvanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and

Characteristics of inhomogeneously filled double L-septa waveguides

open access: yes, 1992
Three types of inhomogeneous double L-septa guide (DLSG) produced by selective dielectric loading of the different regions are analyzed. The cutoff and bandwidth characteristics of these configurations are compared with the inhomogeneous T-septa guide ...

Sarbecoviruses Suppress Innate Immunity by Recruiting PPM1A to Modulate STAT2 and ORF9b Phosphorylation

open access: yesAdvanced Science, EarlyView.
Sarbecovirus ORF9b recruits host phosphatase PPM1A to suppress innate immunity through dual mechanisms. PPM1A directly dephosphorylates ORF9b to sustain its activity and indirectly downregulates STAT2 phosphorylation to impair interferon signaling. Pharmacological inhibition of PPM1A restores antiviral responses and limits sarbecovirus replication ...

Alkylating Agent–Induced FANCL Impairment Damages Pulmonary Arterial, Venous, and Microvascular Endothelial Cells and Predisposes to PAH/PVOD

open access: yesAdvanced Science, EarlyView.
This study establishes a novel cisplatin‐induced rat model of PAH/PVOD and identifies a conserved mechanistic axis—FANCL impairment, DNA damage accumulation, and endothelial dysfunction—triggered by cisplatin or mitomycin C across pulmonary arteries, veins, and microvessels.
