A biofuel cell of (methyl violet/AuNPs)/FTO photoanode and bilirubin oxidase/CuCoO bio-photocathode inspired by the photoelectrochemistry activities of fluorescent materials/molecules.

Herein, we discuss the idea that fluorescent materials/molecules should logically show potential photoelectrochemistry (PEC) activity, and, in particular, the PEC of fluorescent small molecules (previously usually acting only as dye sensitizers for conventional semiconductors) is explored. After examining the PEC activities of some typical inorganic or organic fluorescent materials/molecules and by adopting methyl violet (MV) with the highest PEC activity among the examined fluorescent small molecules, a new and efficient (MV/Au nanoparticles (AuNPs))/fluorine-doped tin oxide (FTO) photoanode without conventional semiconductor(s) is prepared by layer-by-layer alternating the electrodeposition of AuNPs and the adsorption of MV. A bilirubin oxidase (BOD)/CuCoO/FTO bio-photocathode is prepared by electrodeposition, calcination and cast-coating.

In Situ Proefferocytosis Microspheres as Macrophage Polarity Converters Accelerate Osteoarthritis Treatment.

Efferocytosis in macrophages typically engages an anti-inflammatory positive feedback regulatory mechanism. In osteoarthritis (OA), characterized by imbalanced inflammatory homeostasis, the proinflammatory state of macrophages in the immune microenvironment can be reversed through enhanced efferocytosis. This study develops an in situ proefferocytosis hydrogel microsphere (macrophage polarity converter, H-C@IL) for OA treatment.

[Study of the feasibility of polar body transfer combined with preimplantation genetic testing for blocking the intergenerational transmission of mitochondrial genetic diseases].

Objective: To assess the feasibility of first polar body transfer (PB1T) combined with preimplantation mitochondrial genetic testing for blocking the transmission of a pathogenic mitochondrial DNA 8993T>G mutation.

Methods: A Chinese family affected with Leigh syndrome which had attended the Reproductive Medicine Centre of the First Affiliated Hospital of Anhui Medical University in September 2021 was selected as the study subject. Controlled ovarian hyperstimulation was carried out for the proband after completing the detection of the mitochondrial DNA 8993T>G mutation load among the pedigree members.

[Clinical significance of trisomy 7 signaled by non-invasive prenatal testing and a literature review].

Objective: To explore the clinical significance of trisomy 7 signaled by non-invasive prenatal testing (NIPT).

Methods: Pregnant women with high risk for trisomy 7 by NIPT from January 2017 to December 2023 were selected as the study subjects, and the results of prenatal diagnosis and follow-up were analyzed. Literature related to pregnant women with a high risk for trisomy 7 by NIPT from January 2016 to July 2024 was retrieved from China Biomedical Literature Database, Wanfang Database, China National Knowledge Infrastructure and PubMed database.

Factors affecting the quality of postoperative rehabilitation in children with cochlear implants based on the theory of knowledge, attitude and practice.

Objectives: This study aimed to examine factors that influence postoperative rehabilitation outcomes in children with cochlear implants, using a knowledge-attitude-practice (KAP) framework.

Design: A total of 683 children with cochlear implants participated in this study. Hearing and speech assessments were conducted through face-to-face and/or telephone interviews, while parents' or guardians' KAP were assessed following detailed instructions provided beforehand.
