Use of Nuclear Magnetic Resonance Imaging Angiography to Follow-Up Arterial Remodeling in an Animal Model [PDF]

, 1998
Appropriately sized arteries in small animals may be possible models for studying the remodeling process as occurs after arterial balloon injury in humans. Magnetic resonance imaging (MRI) is able to noninvasively image tissue in vivo.

Dual‐Energy CT‐Based Assessment of Thrombotic Heterogeneity for Predicting Stroke Source and Response to Machine Thrombectomy: A Step Toward Visualization Thrombus Treatment

Advanced Science, EarlyView.
The research indicates that dual energy CT scanning can accurately predict the stroke source and clinical outcomes by analyzing thrombus heterogeneity. Based on histopathological analysis of thrombus components, these scans are better able to display thrombus details than standard CT scans, which is helpful for the development of visual navigation ...

Leptin Aggravates Thoracic Aortic Dissection Through Impairment of Energy Metabolism in Nrip2+ Smooth Muscle Cells

Advanced Science, EarlyView.
Epidemiological data confirm obesity elevates thoracic aortic dissection (TAD) risk. Patient analyses implicate hyperleptinemia, where leptin binding to vascular smooth muscle cell (VSMC) receptors triggers Socs3‐mediated suppression of Stat5a transcriptional activity.

Dopamine D1 Receptor Contributes to Glucocorticoid‐Associated Osteonecrosis of Femoral Head Protection Through the ATF3/CHOP Axis to Inhibit Osteoblastic Apoptosis

Advanced Science, EarlyView.
This work identifies a novel mechanism by which dopamine D1 receptor (DRD1) contributes to the pathogenesis of glucocorticoid (GC)‐associated osteonecrosis of the femoral head (ONFH) through the regulation of osteoblastic apoptosis, indicating that DRD1 serves as a critical mediator of the crosstalk between the nervous and skeletal systems.

A novel ultrafast-low-dose computed tomography protocol allows concomitant coronary artery evaluation and lung cancer screening [PDF]

, 2018
BACKGROUND:Cardiac computed tomography (CT) is often performed in patients who are at high risk for lung cancer in whom screening is currently recommended.

Lysosomal Cathepsin S Escape Facilitates Near Infrared Light‐Triggered Pyroptosis Via an Antibody‐Indocyanine Green Conjugate

Advanced Science, EarlyView.
ICAM1 antibody‐bound ICG triggers tumor‐specific, caspase‐1‐independent pyroptosis via CTSS‐mediated GSDMD cleavage, activates antitumor immunity, and synergizes with anti–PD‐1 therapy, offering a non‐apoptotic strategy to overcome resistance in cancer treatment.

Long Non‐Coding RNA IGFRIL Couples with PTBP1 to Destabilize IGFBP3 mRNA to Promote the IGF1R‐AKT‐mTOR Axis and Hepatocellular Carcinoma

Advanced Science, EarlyView.
The limited understanding of IGFR pathway activation hinders its clinical application in HCC. Here, IGFRIL is identified as a novel non‐coding activator of the IGF1R, which recruits PTBP1 to destabilize IGFBP3 mRNA and activates IGF1R, and proposes IGFRIL as a novel actionable target for HCC patients.

PDZK1 Protects Against RPE Senescence by Targeting the 14‐3‐3ε‐mTOR Axis to Attenuate Early Diabetic Retinopathy

Advanced Science, EarlyView.
PDZK1 down‐regulation couples high‐glucose stress to RPE senescence via a PDZK1–14‐3‐3ε–mTOR axis. Restoring PDZK1 or clearing senescent cells rescues retinal homeostasis and mitigates early diabetic retinopathy (DR). This study provides direct evidence linking RPE cell senescence to DR pathogenesis and reveals a promising therapeutic strategy for DR ...

Predicting blunt cerebrovascular injury in pediatric trauma: Validation of the Utah Score [PDF]

, 2017
Risk factors for blunt cerebrovascular injury (BCVI) may differ between children and adults, suggesting that children at low risk for BCVI after trauma receive unnecessary computed tomography angiography (CTA) and high-dose radiation.
