A de‐novo Approach Towards Divergent [3+2π/σ] Photocycloadditions of Nitrones via Assembly‐Controlled Kinetic Electron Transfer Gating

open access: yesAngewandte Chemie, EarlyView.
A metal‐free photocatalytic platform converts nitrones into 4‐isoxazolines and oxa–aza–bicycloheptanes through divergent [3+2π/σ] cycloadditions. Assembly‐controlled kinetic electron transfer gating dictates substrate activation, enabling selective reactivity beyond thermodynamic expectations.

Sleep Disturbances in Adults With Tuberous Sclerosis Complex: Influences of Treatment and Clinical Features

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Tuberous sclerosis complex (TSC) is a genetic condition with multisystem neurocutaneous signs, including hamartomas, epilepsy, and neuropsychological difficulties. Although sleep disorders are increasingly recognized in TSC, they remain poorly described in adults.

A Conserved Isoleucine Gates the Diffusion of CO and O2 to the Active Site of NiFe CO‐Dehydrogenase

open access: yesAngewandte Chemie, EarlyView.
A combination of protein film electrochemistry and site‐directed mutagenesis shows that isoleucine 563 (numbering of Thermococcus sp. AM4) gates the arrival of both CO and O2 to the active site of the nickel‐iron CO dehydrogenases. Mutations at this position increase the resistance to O2 at the cost of a slower reaction with CO.

Assessment of Growth in Cardio‐Facio‐Cutaneous Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cardio‐facio‐cutaneous (CFC) syndrome is a rare, multiple congenital anomaly disorder in which individuals commonly experience faltering growth; however, systematic analysis of growth parameters in this disorder has not been performed. We recruited 69 participants with CFC through CFC International and collected data on assessing height ...

Microenvironmental Tuning in Isostructural Conjugated Metal–Organic Frameworks for Superior Photocatalytic H2O2 Generation

open access: yesAngewandte Chemie, EarlyView.
Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

Biologics Adoption in CRSwNP and the Associated Decline in Endoscopic Sinus Surgery: A Longitudinal Claims Database Study

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Biologic treatments were introduced for chronic rhinosinusitis with nasal polyps (CRSwNP) in 2019. Treatment algorithms for medically refractory CRSwNP remain open, with patients choosing among surgery, biologics, or both. Real‐world utilization of surgery and biologics remains incompletely characterized.

Blood SOD1 Activity in ALS Patients Receiving Tofersen Treatment

open access: yesAnnals of Neurology, EarlyView.
Objective The antisense oligonucleotide tofersen is the first disease‐modifying drug for SOD1‐related amyotrophic lateral sclerosis (ALS) and was approved because of its ability to reduce SOD1 protein and neurofilament levels. The effect of tofersen on SOD1 activity is unclear but of clinical relevance because homozygous SOD1 mutations, linked to ...

Silk Fibroin for Cardiovascular Medical Devices: Review of Material Properties, Applications, and Clinical Potential

open access: yesAdvanced NanoBiomed Research, EarlyView.
Silk fibroin is an attractive natural biomaterial that can be engineered into diverse cardiovascular constructs, including vascular grafts, cardiac patches, heart valves, and stent coatings. Its tunable biological and mechanical properties have driven substantial preclinical progress; however, widespread clinical translation in cardiovascular ...
