Remote Ischemic Post‐Conditioning Preserves the Neurovascular Unit by Brain‐Derived Gas6 That Drives Monocyte‐Derived Macrophage Reprogramming via Axl and Vimentin after SAH

Advanced Science, EarlyView.
Subarachnoid hemorrhage (SAH) triggers monocyte‐derived macrophage (MDM) infiltration and M1‐like polarization via Vimentin upregulation, leading to neurovascular unit disruption and cognitive dysfunction. Remote ischemic postconditioning (RIPostC) upregulates neuronal Gas6, which activates Axl on MDMs to downregulate Vimentin and drive reparative M2 ...

Stenting as a Rescue Treatment of a Pulmonary Artery False Aneurysm Caused by Swan-Ganz Catheterization

Case Reports in Pulmonology, 2014
Pulmonary vascular injury is a rare but life-threatening complication of Swan-Ganz catheterization. We report an 82-year old patient who underwent right heart catheterization by a balloon-tipped catheter because of suspected pulmonary hypertension. After

NCOA4 Accelerates Abdominal Aortic Aneurysm Formation by Regulating Macrophage Activation and Ferroptosis via STAT1–CH25H Axis

Advanced Science, EarlyView.
Under pathological stimulation, NCOA4 in macrophages interacts with STAT1 to promote CH25H transcription. The subsequent increase in 25‐HC production activates macrophages, triggers inflammatory responses and ferroptosis, and accelerates the progression of AAA.

Ultrasound‐Triggered piRNA Delivery Using Biomimetic Phase‐Changeable Nanoparticles for Theranostics of Myocardial Infarction

Advanced Science, EarlyView.
A biomimetic ultrasound‐responsive piRNA delivery nanoparticle platform (piR‐NPs) enables targeted delivery and ultrasound (US)‐triggered release of piR‐1873 in infarcted myocardium. The released piR‐1873 suppresses Usp2‐mediated RIP1/RIP3/MLKL necroptosis, reduces myocardial injury and fibrosis, and promotes cardiac functional recovery, providing a ...

Stroke‐Heart Syndrome: Mechanisms, Temporal Phenotypes, and Diagnostic Reasoning

Advanced Science, EarlyView.
Stroke‐heart syndrome describes new or worsened cardiac abnormalities after acute stroke. This Review defines its clinical boundaries, traces autonomic, inflammatory, endothelial, and supply‐demand mechanisms across time, and proposes provisional phenotypes that integrate lesion location, premorbid cardiac substrate, serial biomarkers ...

True aneurysm of common digital artery: Case report [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2008
INTRODUCTION Aneurysms of digital arteries are considered to be rarity. They could be true or false. False aneurysms are usually the result of penetrating trauma, while the causes of development of true aneurysms are various, such as blunt trauma, and ...

Abdominal POCUS Education for Clinicians: A Systematic Review of Teaching Methods for Point‐of‐Care Abdominal Ultrasonography

Journal of Clinical Ultrasound, Volume 53, Issue 3, Page 547-561, March/April 2025.
For patients to benefit from abdominal point‐of‐care ultrasound, the ultrasound examinator must be sufficiently trained. In this systematic review, we identified advantages and disadvantages of different training methods and approaches. We conclude that thoughtful integration of the various educational methods is crucial for stakeholders and educators.
