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

open access: yesAdvanced 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 ...

Expanded Hepatic Progenitor Cells Featured with Aggregation of α‐Synuclein Contribute to Pathologic Bile Duct Regeneration in Biliary Atresia

open access: yesAdvanced Science, EarlyView.
Expanded NCAM1+EpCAM+ hepatic progenitor cells in biliary atresia are characterized by aggregation of α‐synuclein. This pathological protein potentiates cellular susceptibility to GSH‐dependent redox dyshomeostasis, induces unstable biliary cell fate specification, and subsequently drives aberrant biliary regeneration.

Single‐Cell Reveal GALNT7‐Dependent Ferroptosis Suppression as a Mechanism of Immunotherapy Resistance in Non‐Small Cell Lung Cancer

open access: yesAdvanced Science, EarlyView.
Integrated clinical and mechanistic analyses identify GALNT7 as a ferroptosis‐suppressive regulator associated with immunotherapy resistance in non‐small cell lung cancer. GALNT7 depletion promotes lipid peroxidation, mitochondrial dysfunction, and ferroptosis, enhances CD8+ T‐cell activation and IFN‐γ production, and sensitizes tumors to PD‐1 blockade,

THE STORY BEHIND THE STATISTICS: ON THE DIGITAL COMPETENCES OF ROMANIAN YOUTH [PDF]

open access: yesRevista Română de Sociologie, 2016
After a critical review of the „digital competences” concept (Lankshear, Knobel, 2008), and the argumentation of the importance of studying them in the context of the second level digital divide (Hargittai, 2001), in our study we aimed to analyze the ...

The KIF6‐RBP Complex Orchestrates mRNA Transport Required for Sperm Flagellar Assembly

open access: yesAdvanced Science, EarlyView.
Two homozygous deleterious KIF6 variants are identified in unrelated men with impaired sperm motility. Mouse models and multi‐omics analyses reveal that KIF6 cooperates with the RNA‐binding proteins FMRP and FXR1 to deliver mRNAs essential for sperm flagellar assembly, linking disrupted mRNA transport to reduced abundance of key structural and ...

Assessment of digital competences of elementary school students [PDF]

open access: yes, 2018
U ovom diplomskom radu teorijskim djelom prikazan je pojam kompetencija koje se sve više pojavljuju u odgoju i obrazovanju. Rad je napisan na području Informatike, stoga je većina teorije posvećena digitalnim kompetencijama.
