Article Abstract

Background: Hearing loss is a common sensorineural dysfunction with a high incidence in China. Although genetic factors are important causes of hearing loss, hearing-related gene detection has not been widely adopted in China.

Objective: Establishing a rapid and efficient method to simultaneously detect hotspot hearing loss gene mutations.

Methods: A reverse dot blot assay combined with a flow-through hybridization technique was developed for the simultaneous detection of 13 hotspot mutations of 4 hearing loss-related genes including and the mitochondrial gene . This method involved PCR amplification systems and a hybridization platform.

Results: The technique can detect 13 hotspot mutations of 4 hearing loss-related genes. And a total of 213 blood samples were used to evaluate the availability of this method.

Discussion: Our reverse dot blot assay was a simple, rapid, accurate, and cost-effective method to identify hotspot mutations of 4 hearing loss-related genes in a Chinese population.

pH-gated bidirectional nanoassembly switches: self-ratiometric D-penicillamine sensing AIE-active Au(I)-TCEP-Cd(II) coordination dynamics.

Self-assembly is regarded as a facile method to fabricate luminescent nanomaterials with aggregation induced emission (AIE) properties for optical sensor design. In this work, a pH-controlled self-ratiometric sensing platform utilizing aggregation-induced emission (AIE)-active Au(I)-TCEP-Cd(II) nanoaggregates was developed for highly reliable D-penicillamine (DPA) detection. Through stoichiometric coordination with Cd, oligomeric Au(I)-tris(2-carboxyethyl)phosphine (TCEP) complexes could self-assemble into snowflake-like nanoaggregates (∼100 nm) with strong yellow emission (540 nm) and excellent aqueous stability.

Heavy-metal-free III-V semiconductor-based colloidal quantum dots (CQDs), such as InAs, are promising candidates for near- and short-wave infrared detection. However, up-to-date research efforts remain mainly limited to wavelengths below 1100 nm due to challenges in synthesis, junction formation, and passivation for large diameter InAs quantum dots. Systematic investigations into device design, reverse dark current mechanisms, and trap distributions in larger InAs quantum dots remain limited.

Controlled modulation of charge storage and recombination in light-emitting diodes (LEDs) can function as an artificial memory platform, where charge storage mimics data writing, and recombination corresponds to data readout. Here we demonstrate hole storage lasting up to 0.8 s in an LED using the Cu-In-Zn-S quantum-dot (QD) emissive layer coupled with a deep-energy-level hole transport layer (HTL).

A novel derivative of rhein overcomes temozolomide resistance in glioblastoma by regulating SOX9 through mA methylation.

Temozolomide (TMZ) resistance remains a critical barrier to effective treatment of glioblastoma (GBM), the most aggressive form of glioma. Fat mass and obesity-associated protein (FTO), an mA demethylase, has been implicated in tumor progression and chemoresistance. SYSUP007, a novel derivative of the FTO inhibitor rhein, exhibits anti-glioma activity; however, its role in modulating TMZ resistance remains unexplored.

Background: Glaucoma, a leading cause of irreversible blindness worldwide, is characterized by progressive retinal ganglion cells (RGCs) degeneration. The accumulation of glutamate in the retina is a common mechanism underlying the of RGCs death in various forms of glaucoma. Neuroprotective strategies for RGCs remain an unmet need, urging exploration of novel molecular mechanisms beyond intraocular pressure (IOP) control.
