Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Estimated pretreatment hemodynamic prognostic factors of aneurysm recurrence after endovascular embolization. [PDF]

, 2017
BACKGROUND:Hemodynamic factors play important roles in aneurysm recurrence after endovascular treatment. OBJECTIVE:Predicting the risk of recurrence by hemodynamic analysis using an untreated aneurysm model is important because such prediction is ...

Single‐Cell RNA Sequencing of Retina Reveals Nna1 Upregulation in Myopic Diabetic Retinopathy as a Protective Factor Against Diabetic Damage

Advanced Science, EarlyView.
This study investigates a schematic overview of the mechanistic pathways. The relationship between myopia and DR has long been of clinical interest. In diabetic mice, Nna1 expression is downregulated, whereas in diabetic mice with FDM, Nna1 expression is upregulated–particularly in Müller cells–accompanied by decreased vascular endothelial growth ...

Underuse of coronary revascularization procedures in patients considered appropriate candidates for revascularization. [PDF]

, 2001
Background: Ratings by an expert panel of the appropriateness of treatments may offer better guidance for clinical practice than the variable decisions of individual clinicians, yet there have been no prospective studies of clinical outcomes. We compared

Antiemesis Corticosteroids Potentiate Checkpoint Blockade Efficacy by Normalizing the Immune Microenvironment in Metastatic Murine Breast Cancer

Advanced Science, EarlyView.
Corticosteroids improve the efficacy of immune checkpoint blockade therapy in metastatic murine breast cancer. By normalizing the tumor immune microenvironment, corticosteroids reduce immunosuppressive signals, restore T‐cell function, and promote antitumor immune responses, resulting in enhanced tumor control.
