Engineered Exosomal miR‐146a‐5p Reprograms BMSC Fate and Restores Mitochondrial Homeostasis in Glucocorticoid‐Induced Osteonecrosis of Femoral Head

Advanced Science, EarlyView.
Exosomal miR‐146a‐5p is identified as a pivotal regulator in steroid‐induced osteonecrosis. Its reduction activates NF‐κB signaling, compromises mitophagy, and disrupts mitochondrial bioenergetics, resulting in autophagic disequilibrium. Engineered exosomes delivering miR‐146a‐5p reinstate mitochondrial function, augment oxidative phosphorylation and ...

Nodal sets for solutions of elliptic equations

Journal of Differential Geometry, 1989
On etudie, sur un domaine connexe Ω⊂R n , l'ensemble zero u −1 {0} d'une solution u d'une equation elliptique a ij D i D j u+b j D j u+cu=0 ou a ij , b j , c sont bornes et a ij est continu. On demontre que la mesure de Hausdorff a (n−1) dimensions de u − 1 {0} est finie dans un voisinage d'un point x 0 ∈Ω ou u a un ordre fini d ...

2D Inorganic Electrides: Interstitial Electrons as Key Drivers of Multifunctional Properties and Applications

Advanced Science, EarlyView.
Eight AB‐type 2D inorganic electrides with negatively charged transition metals are theoretically designed. Their monolayers exhibit intrinsic magnetic ordering, rich topological phases, and ultralow work functions. Supported metal Ru on these 2D inorganic electrides effectively alleviates hydrogen poisoning and enables efficient ammonia synthesis ...

European guidelines from the EHTG and ESCP for Lynch syndrome: an updated third edition of the Mallorca guidelines based on gene and gender

BJS (British Journal of Surgery), EarlyView., 2020
Recommendations for clinical and molecular identification of LS, surgical and endoscopic management of LS‐associated colorectal cancer and preventive measures for cancer were produced. The emphasis was on surgical and gastroenterological aspects of the cancer spectrum.

Real‐Time Stress Visualization of Hydrogels Enabled by Supramolecularly Switched Stretch‐Induced Phase Separation

Advanced Science, EarlyView.
Supramolecular hydrogels enable real‐time visualization of mechanical stress through supramolecular switching mechanotransduction. Adamantane‐modified cellulose functions as a responsive domain that undergoes an on–off transition between hydrated and dehydrated states via reversible β‐cyclodextrin–adamantane complexation and decomplexation.

Long‐term prognosis is associated with residual disease after neoadjuvant systemic therapy but not with initial nodal status

BJS (British Journal of Surgery), EarlyView., 2020
This long‐term follow‐up study determined survival rates in a Swedish national cohort of 417 patients with breast cancer who all had neoadjuvant systemic therapy (NAST). Sentinel lymph node biopsy (SLNB) was performed before NAST in clinically node‐negative and after NAST in clinically node‐positive patients.

Nodal DG-FEM solution of high-order Boussinesq-type equations [PDF]

A discontinuous Galerkin finite-element method (DG-FEM) solution to a set of high-order Boussinesq-type equations for modelling highly nonlinear and dispersive water waves in one horizontal dimension is presented. The continuous equations are discretized
