Insights Into Remote Ischemic Conditioning miRNA Effects on Brain Endothelial Cells During Ischemia–Reperfusion

open access: yesMicrocirculation, Volume 33, Issue 4, May 2026.
ABSTRACT Objective Acute ischemic stroke (AIS) is one of the leading causes of death and disabilities, and as such, it is of utmost importance to identify novel treatment options. Remote ischemic conditioning (RIC) is a promising non‐invasive treatment that is thought to activate the body's own protective mechanisms against damaging ischemia.

Infection Complications in Pediatric Patients With Inborn Errors of Immunity After Umbilical Cord Blood Transplantation: A Chinese Single‐Center Study

open access: yesTransplant Infectious Disease, Volume 28, Issue 3, May/June 2026.
This study reveals that infections are highly prevalent in pediatric IEI patients after umbilical cord blood transplantation, with early‐stage infections and bloodstream infections strongly associated with poorer survival. These findings advocate for risk‐stratified surveillance and preemptive strategies in high‐risk subgroups.

Structure of the G protein chaperone and guanine nucleotide exchange factor Ric-8A bound to Gαi1 [PDF]

open access: yes, 2020
Ric-8A is a cytosolic Guanine Nucleotide exchange Factor (GEF) that activates heterotrimeric G protein alpha subunits (Gα) and serves as an essential Gα chaperone.

The nucleotide exchange factor Ric-8A is a chaperone for the conformationally dynamic nucleotide-free state of Gαi1. [PDF]

open access: yes, 2011
Heterotrimeric G protein α subunits are activated upon exchange of GDP for GTP at the nucleotide binding site of Gα, catalyzed by guanine nucleotide exchange factors (GEFs). In addition to transmembrane G protein-coupled receptors (GPCRs), which act on G

Elucidating Thermally Enhanced Luminescence in Au(III) Complexes for High‐Performance Organic Light Emitting Diodes

open access: yesAdvanced Optical Materials, Volume 14, Issue 15, 17 April 2026.
We report a series of Au(III) complexes incorporating asymmetric carbazolyl motifs that regulate co‐facial distance between donor and acceptor moieties. Femtosecond transient absorption and density functional theory computation analyses reveal rapid reverse internal upconversion from the lowest triplet state (T1) to a thermally accessible higher‐lying ...

Absorption‐Dominant Electromagnetic Interference Shielding of Ti3C2Tx MXene‐Coated and Fe3O4‐Integrated TPMS Composites with Coupled Gradient Conductivity and Size‐Graded Structure

open access: yesAdvanced Science, Volume 13, Issue 22, 17 April 2026.
A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

Neuroprotective Effect of Remote Ischemic Conditioning on Patients Undergoing Intravenous Thrombolysis: A Randomized Controlled Trial

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Adjunctive remote ischemic conditioning (RIC) administered twice within 24 h after intravenous thrombolysis (IVT) improved cerebral autoregulation, suggesting that RIC exerted neuroprotective effects in patients undergoing IVT. ABSTRACT Intravenous thrombolysis (IVT) is the treatment with the highest level of evidence for acute ischemic stroke, but ...
