Created Ex Nihilo: A Near‐Infrared Afterglow Luminescent Framework of Imidazole Derivatives for Bioimaging

open access: yesAngewandte Chemie, EarlyView.
A series of Ir(III) complexes (Ir‐1‐Ir‐4) based on imidazole derivatives provide a new afterglow luminescence mechanism. The work expands the range of afterglow luminescence frameworks to overcome: (i) a lack of new afterglow scaffolds; (ii) the dependence on initial external light activation; and (iii) aggregation‐caused quenching.

Novel ultralow positioning of the umbilical artery catheter: A prospective pilot study

open access: yesJournal of Ultrasonography
Thrombosis is a common complication of umbilical artery catheterization. The purpose of this study was to compare the novel ultralow umbilical artery catheter position (catheter tip at the junction of the umbilical and internal iliac arteries) versus the

ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

open access: yesAdvanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

Developing Highly Effective Nanoparticle mRNA Therapeutic for Pediatric Acute Respiratory Distress Syndrome

open access: yesAdvanced Science, EarlyView.
Sepsis‑induced pediatric acute respiratory distress syndrome suppresses FOXF1 in lung endothelial cells which causes life‐threatening lung damage. To counter this, researchers developed nanoparticles that specifically target these cells and deliver FOXF1 mRNA.

Late coronary complications after arterial switch operation for transposition of great arteries : clinical and therapeutic implications [PDF]

open access: yes, 2005
The arterial switch operation is the procedure of choice for correction of transposition of the great arteries. Although offering excellent long term results, this procedure is burdened by the risk of acute and subacute coronary occlusion.

Extracellular Vesicle Packaged TDP43 Derived From ECs Exacerbates Cigarette Tar‐Related Atherosclerosis Progression via Enhancing Macrophage Extracellular Traps

open access: yesAdvanced Science, EarlyView.
Cigarette tar triggers EC‐derived EVs carrying TDP43, which binds VDAC1 to boost MAMs, mitochondrial Ca2+ overload, and METs formation in macrophages, accelerating smoking‐related AS progression, while retinoic acid binds TDP43 to block this pathogenic cascade.

Structural plasticity and isolation of umbilical cord progenitor cells of agouti (Dasyprocta prymnolopha) raised in captivity

open access: yesSemina: Ciências Agrárias, 2019
The agouti has been used as an experimental model in several studies focused on reproductive biology. The umbilical cord, an embryonic attachment that connects the foetus to the placenta, has been reported as an important anatomical site for obtaining ...
