Promotion of cardiac microtissue assembly within G-CSF-enriched collagen I-cardiogel hybrid hydrogel.

Tissue engineering as an interdisciplinary field of biomedical sciences has raised many hopes in the treatment of cardiovascular diseases as well as development of three-dimensional (3D) cardiac models. This study aimed to engineer a cardiac microtissue using a natural hybrid hydrogel enriched by granulocyte colony-stimulating factor (G-CSF), a bone marrow-derived growth factor. Cardiac ECM hydrogel (Cardiogel: CG) was mixed with collagen type I (ColI) to form the hybrid hydrogel, which was tested for mechanical and biological properties.

Nurses' bereavement experiences of a deceased colleague due to COVID-19: A phenomenological study.

Aim: Healthcare workers have little time to mourn due to the intensification of the COVID-19 pandemic. Although grief is a normal part of life and death, the circumstances surrounding the death can affect the grieving process. So far, the nurses' experience in mourn for a deceased colleague in the COVID-19 pandemic has not been determined.

Folic acid-conjugated dextran-coated ZnMnFeO nanoparticles as systemically delivered nano heaters with self-regulating temperature for magnetic hyperthermia therapy of liver tumors.

Successful cancer treatment using magnetic hyperthermia therapy (MHT) strongly depends on biocompatible magnetic nanoparticles (NPs). They can effectively accumulate in tumor tissues after systemic injection and generate heat in the therapeutic temperature range (42-48 °C) by exposure to an AC magnetic field (AMF). For this purpose, folic acid-conjugated dextran-coated ZnMnFeO (FA-Dex-ZMF) NPs were synthesized as smart nano heaters with self-regulating temperatures for MHT of liver tumors.
