Therapeutic Silencing of Tmprss6 Reduces Iron‐Induced Inflammation and Prolongs Survival in MDS Mice

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic disorders characterized by ineffective hematopoiesis, cytopenias, and an increased risk of progression to acute myeloid leukemia (AML). Despite advances in supportive and targeted therapies, disease‐modifying interventions remain limited.

Assessment of Contact Laws Accounting for Softening in 3D Rigid Concrete Particle Models

open access: yesBuildings
To obtain predictions closer to concrete behaviour, it is necessary to employ a particle model (PM) that considers contact softening. A bilinear softening contact model (BL) has been adopted in PM studies.

Mesoporous Silica Nanoparticles With Customized Drug Ratio/Loading for Effective Treatment of Gemcitabine‐Resistant Pancreatic Tumors

open access: yesAdvanced NanoBiomed Research, EarlyView.
Redox responsive mesoporous silica nanoparticles (MSNs) were engineered to deliver gemcitabine (Gem) and cisplatin (cisPt) at defined ratios to overcome chemoresistance in pancreatic ductal adenocarcinoma (PDAC). Optimized Gem MSNs and Gem cisPt MSNs enhanced cytotoxicity in murine and human Gem resistant models, with select formulations inducing ...

Effects of Geometry, Joint Properties, and Deterioration Scenarios on the Hydromechanical Response of Gravity Dams

open access: yesApplied Mechanics
An explicit coupled two-dimensional (2D) hydromechanical model (HMM) that can simulate discontinuous features in the foundation, as well as the effects of grout curtains and drainage systems, is employed to evaluate the influence of key parameters such ...

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.
