The demand for multimodal nanomaterials has intensified in recent years driven by the need for ultrasensitive bioimaging probes and accurate temperature monitoring in biological objects. Among the different multimodal nanomaterials that have been extensively studied in the past decade, upconverting nanoparticles are among the most promising. In this paper, we report the synthesis of upconverting nanoparticles with complex core-shell compositions, capable of being excited by 808 or 980 nm laser irradiation and exhibiting a good MRI response.

- Graphene oxide (GO) demonstrates high absorption capabilities and can significantly impact fish embryos and larvae when combined with a heavy metal mixture (Cr, Cu, Ni, Zn).
- Experiments showed that GO accumulates in the embryo chorion and affects heart rate and metal levels, while larvae show genotoxic impacts but no significant changes in vital signs.
- The study concludes that while GO combined with heavy metals is less toxic for larvae than the metals alone, exposure to GO, even at low concentrations, poses health risks that need attention.
Many inland ecosystems (lakes, rivers, reservoirs, lagoons) around the world undergo regular biological monitoring surveys, including monitoring the abundance, biomass and size structure of fish communities. Yet, the majority of fish monitoring datasets for inland ecosystems remain inaccessible. This is especially true for historical datasets from the early and middle 20 century, despite their immense importance for establishing baselines of ecosystem status (e.

Aim: To study the clinical significance of the cardio-ankle vascular index (CAVI) in patients with stroke.
Material And Methods: The study included 374 post-stroke patients. The state of peripheral arteries was assessed using CAVI and the ankle-shoulder index (ASI).
