Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

Advanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Ex vivo renal perfusion and autotransplantation in treatment of calculous disease or abdominal aortic aneurysm. [PDF]

, 1975
Two more indications are described for temporary ex vivo perfusion of kidneys with revascularization of these organs as autografts to orthotopic or heterotopic locations. One of the patients had staghorn calculi which were removed from a solitary kidney.

A Nano‐Interception Strategy for Chronic Heart Failure: Prussian Blue Nanoparticles Disrupt Fibroblast‐Immune Communication via CCL2 Sequestration

Advanced Materials, EarlyView.
A nano‐interception strategy disrupts pathogenic fibroblast–macrophage crosstalk in chronic heart failure. Scalable Prussian blue nanoparticles selectively sequester CCL2 via ultrahigh‐affinity binding, preventing CCR2+ macrophage recruitment and breaking a key fibro‐inflammatory circuit. This approach demonstrates robust efficacy in murine and porcine

Study on mercury in dental calculus.

THE JOURNAL OF THE STOMATOLOGICAL SOCIETY,JAPAN, 1989
It has been reported that dental calculus contains trace elements of mercury besides lead, cadmium and zinc. The mercury is one of the hazardous metal elements from the environmental point of view. The purpose of this study was to clarify the mechanism of the accumulation of mercury in the dental calculus. The results were as follows: 1.

Engineered Heparinized GQDS/HPEI–Polyamide Membrane for Bilirubin Removal via One Step Anti Coagulation

Advanced Materials Interfaces, EarlyView.
A multifunctional heparinized polyamide membrane embedded with graphene quantum dots (GQDs) and hyperbranched polyethyleneimine (HPEI) is engineered for efficient bilirubin removal via a one‐step anticoagulation–adsorption process. The membrane demonstrates enhanced hemocompatibility, prolonged clotting times, and high bilirubin adsorption capacity ...

Biofluorescence imaging as a valid alternative for dental calculus detection

Photodiagnosis and Photodynamic Therapy
Background: Dental calculus is a major contributor to periodontal disease, and its effective removal depends on accurate detection. This study aimed to evaluate the detectability of dental calculus using quantitative biofluorescence imaging (BFI) and to ...

Nitric Oxide‐Generating Poly (allylamine hydrochloride) Coating on Biomedical Titanium Implant

Advanced Materials Interfaces, EarlyView.
We report a metal‐free, nitric oxide (NO)‐generating coating in which poly(allylamine hydrochloride) (PAH) is covalently immobilized onto titanium. The coating catalyzes NO generation from the endogenous S‐nitrosothiol GSNO, retains activity after multiple reuse cycles and pH exposures, and maintains endothelial cell viability while modulating ...

Crack Repair in Hydroxyapatite Bioceramics Using an Ultraviolet Ultrafast Laser

Advanced Materials Interfaces, EarlyView.
The study proposes an ultrafast ultraviolet laser approach to repair hidden tooth cracks, which has been preliminarily validated on HAP. Moreover, this technique aims to strengthen the native enamel structure rather than introducing a foreign filling material.
