Co-overexpression of Atoh1, Pou4f3, and Gfi1 enhances the transdifferentiation of supporting cells into hair cells in the neonatal mouse utricle.

Hair cells (HCs) are essential for vestibular function, and irreversible damage to vestibular HCs in mammals is closely associated with vertigo. The stimulation of HC regeneration through exogenous gene delivery represents an ideal therapeutic approach for restoring vestibular function. Overexpression of Atoh1, Pou4f3, and Gfi1 (collectively referred to as APG) has demonstrated efficacy in promoting HC regeneration in the cochlea.

Spinal Lymphatic Dysfunction Aggravates the Recovery Process After Spinal Cord Injury.

We aimed to evaluate the role of the spinal lymphatic system in spinal cord injury and whether it has an impact on recovery after spinal cord injury. Flow cytometry was used to evaluate the changes in the number of microvesicles after spinal cord injury. Evans blue extravasation was used to evaluate the function of the lymphatic system.

A MnO nanosheet-mediated CRISPR/Cas12a system for the detection of organophosphorus pesticides in environmental water.

Nowadays, easy, convenient, and sensitive sensing strategies are still critical for organophosphorus pesticides in environmental water samples. Herein, a novel organophosphorus pesticide (OP) assay based on acetylcholinesterase (AChE) and a MnO nanosheet-mediated CRISPR/Cas12a reaction is reported. The single-strand DNA (ssDNA) activator of CRISPR/Cas12a was simply adsorbed on the MnO nanosheets as the nanoswitches of the assay.

[Effects of soil moisture on microbial processes of soil nitrogen gases production under anaerobic conditions].

Gaseous nitrogen (N) emission [nitric oxide (NO), nitrous oxide (NO), and nitrogen (N)] is an important pathway of soil N loss. Nitrification and denitrification are the main processes of gaseous N production in soil. However, the contribution of heterotrophic nitrification, co-denitrification, and anammox to gaseous N production remains uncertain.
