Prognostic Value of Epicardial Adipose Tissue in Heart Failure With Mid‐Range and Preserved Ejection Fraction: A Multicenter Study

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Epicardial adipose tissue (EAT) accumulation is thought to play a role in the pathophysiology of heart failure (HF) with mid‐range ejection fraction and HF with preserved ejection fraction, but its effect on outcome is unknown.

Nanobody‐Decorated Lipid Nanoparticles for Enhanced mRNA Delivery to Tumors In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a targeted mRNA‐LNP platform engineered with anti‐PSMA nanobodies for prostate cancer therapy. Using different in vivo models, the authors demonstrate selective uptake and mRNA delivery in PSMA+ cancer cells. However, while targeting is enhanced, mRNA delivery efficacy is limited by tissue penetration, tumor necrosis, and immune ...

Visual versus fully automated assessment of left ventricular ejection fraction

open access: yesAvicenna Journal of Medicine, 2018
Introduction: The aim of this study is to compare three different echocardiographic methods commonly used in the assessment of left ventricle (LV) ejection fraction (EF). Methods: All patients underwent full echocardiography including LVEF assessed using

Immunomodulation With Local, Sustained Delivery of Pituitary Adenylate Cyclase Activating Polypeptide Results in Improved Functional Recovery in Stroke‐Injured Mice

open access: yesAdvanced Healthcare Materials, EarlyView.
The tissue and functional benefits are demonstrated with local, sustained delivery of an anti‐inflammatory peptide, pituitary adenylate cyclase‐activating polypeptide (PACAP), for stroke treatment in a mouse model. Prolonged PACAP treatment modulated astrocyte and microglia toward pro‐reparative phenotypes, enhanced neuroprotection and preservation of ...

Metal Enrichment of the Intergalactic Medium in Cosmological Simulations [PDF]

open access: yes, 2001
Observations have established that the diffuse intergalactic medium (IGM) at z ~ 3 is enriched to ~0.1-1% solar metallicity and that the hot gas in large clusters of galaxies (ICM) is enriched to 1/3-1/2 solar metallicity at z=0.

Digitonin‐Loaded Nanoscale Metal–Organic Framework for Mitochondria‐Targeted Radiotherapy‐Radiodynamic Therapy and Disulfidptosis

open access: yesAdvanced Materials, EarlyView.
A mitochondria‐targeted cationic nanoscale metal organic framework shows strong radiotherapy‐radiodynamic therapy effects and selectively releases digitonin in acidic tumor microenvironments to induce disulfidptosis of cancer cells and downregulate immune checkpoints in cancer and T cells, thereby eliciting strong antitumor immunity to effectively ...

Benefits of Permanent His Bundle Pacing Combined With Atrioventricular Node Ablation in Atrial Fibrillation Patients With Heart Failure With Both Preserved and Reduced Left Ventricular Ejection Fraction

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundClinical benefits from His bundle pacing (HBP) in heart failure patients with preserved and reduced left ventricular ejection fraction are still inconclusive.
