AAV-mediated Gene Therapy for Hereditary Deafness: Progress and Perspectives.

Hereditary deafness is the most prevalent sensory deficit disorder, with over 100 identified deafness-related genes. Clinical treatment options are currently limited to external devices like hearing aids and cochlear implants. Gene therapy has shown promising results in various genetic disorders and has emerged as a potential treatment for hereditary deafness.

Patterns of lymph node metastasis in 441 patients with sinonasal squamous cell carcinoma.

Background: Due to the rarity of sinonasal squamous cell carcinoma (SNSCC), the distribution patterns of lymph node metastasis (LNM), the relationship between LNM and prognosis, and the optimal treatment of LNM lack sufficient evidence-based support.

Objectives: To investigate the patterns of LNM in SNSCC and evaluate the impact of LNM on prognosis.

Design: This was a retrospective cohort study.

LRRC8A drives NADPH oxidase-mediated mitochondrial dysfunction and inflammation in allergic rhinitis.

Objectives: Allergic rhinitis (AR) is a complex disorder with variable pathogenesis. Increasing evidence suggests that the LRRC8A is involved in maintaining cellular stability, regulating immune cell activation and function, and playing significant roles in inflammation. However, the involvement of LRRC8A in AR inflammation and its underlying mechanisms remain unclear.

Comparative study of physicochemical properties on corneal stromal lenticules following four decellularization methods.

This study compares the physicochemical properties of corneal stromal lenticules following decellularization via four methods. Human corneal stromal lenticules, derived from small incision lenticule extraction surgery, underwent decellularization with sodium dodecyl sulfate (SDS), Triton X-100 (Tx) combined with SDS, trypsin-ethylenediaminetetraacetic acid (TE), or NaCl combined with deoxyribonuclease (DNase), respectively. Lenticule DNA and glycosaminoglycan (GAG) content, immunofluorescence staining of cell nuclei and collagen, transparency, biomechanics, histological structure, and immunogenicity were examined in each group and compared with fresh lenticules.

Exposure to particulate matter (PM) weakens corneal defense by downregulating thrombospondin-1 and tight junction proteins.

Background: Fine particulate matter (PM) induces ocular surface toxicity through pyroptosis, oxidative stress, autophagy, and inflammatory responses. However, the precise molecular pathways through which PM causes corneal damage remain unclear. This study aims to investigate the underlying mechanisms by exposing human corneal epithelial cells (HCECs) to PM.

CRISPR-AsCas12f1 couples out-of-protospacer DNA unwinding with exonuclease activity in the sequential target cleavage.

Type V-F CRISPR-Cas12f is a group of hypercompact RNA-guided nucleases that present a versatile in vivo delivery platform for gene therapy. Upon target recognition, Acidibacillus sulfuroxidans Cas12f (AsCas12f1) distinctively engenders three DNA break sites, two of which are located outside the protospacer. Combining ensemble and single-molecule approaches, we elucidate the molecular details underlying AsCas12f1-mediated DNA cleavages.

Computed tomography radiomics reveals prognostic value of immunophenotyping in laryngeal squamous cell carcinoma: a comparison of whole tumor- versus habitats-based approaches.

Background: To compare the performance of whole tumor and habitats-based computed tomography (CT) radiomics for predicting immunophenotyping in laryngeal squamous cell carcinomas (LSCC) and further evaluate the stratified effect of the radiomics model on disease-free survival (DFS) and overall survival (OS) of LSCC patients.

Methods: In all, 106 LSCC patients (40 with inflamed and 66 with non-inflamed immunophenotyping) were randomly assigned into a training (n = 53) and testing (n = 53) cohort. Briefly, 750 radiomics features from contrast-enhanced CT images were respectively extracted from the whole tumor and two Otsu method-derived subregions.

Data free knowledge distillation with feature synthesis and spatial consistency for image analysis.

Privacy and security concerns restrict access to original training datasets, posing significant challenges for model compression. Data-Free Knowledge Distillation (DFKD) emerges as a solution, aiming to transfer knowledge from teacher to student networks without accessing original data. Existing DFKD methods struggle to generate high-quality synthetic samples that capture the complexities of real-world data, leading to suboptimal knowledge transfer.

Impact of radiotherapy on peripheral T lymphocytes in hypopharyngeal squamous cell carcinoma.

Background: To investigate the impact of radiotherapy (RT) on the distribution and function of peripheral CD8 T lymphocytes in patients with hypopharyngeal squamous cell carcinoma (HPSCC).

Methods: A total of 105 HPSCC patients who underwent definitive RT were enrolled. Baseline levels of peripheral immune cells were obtained, and their alteration during RT was evaluated.

Apigenin attenuates cisplatin-induced hair cell damage in the zebrafish lateral line.

Cisplatin, a widely used chemotherapy drug, is notorious for causing ototoxicity, which leads to irreversible sensorineural hearing loss by damaging cochlear sensory hair cells (HCs), spiral ganglion neurons (SGNs), and the stria vascularis (SV). Mechanisms include DNA adduct formation, mitochondrial dysfunction, oxidative stress, and inflammation, ultimately triggering cell death pathways like apoptosis, necroptosis, pyroptosis, or ferroptosis. Apigenin, a natural flavonoid found in various foods and beverages, possesses antioxidant, anti-inflammatory, and anti-tumor properties.

Proton beam irradiation with anti-VEGF therapy for polypoidal choroidal vasculopathy: results of a 24-month, phase II randomized study.

Purpose: To determine the efficacy and safety of proton beam irradiation (PBI) and anti-vascular endothelial growth factor (anti-VEGF) therapy for polypoidal choroidal vasculopathy (PCV)/ aneurysmal type 1 macular neovascularization (AT1).

Methods: The randomized clinical trial consisted of newly diagnosed active PCV/AT1 patients who were randomized 1:1 to treatment with three initial monthly intravitreal anti-VEGF agent (conbercept) injections with or without single 14 GyE radiation. Subsequent anti-VEGF therapy was given pro re nata.

A comprehensive evaluation on the associations between hearing and vision impairments and risk of all-cause and cause-specific dementia: results from cohort study, meta-analysis and Mendelian randomization study.

Background: Epidemiological studies show inconsistent links between hearing/vision impairment and dementia risk. Using multisource data, we investigated how single or combined sensory impairments relate to risks of all-cause and specific types of dementia.

Methods: We employed a triangulation approach combining three methodologies.

[Advances in the research of femtosecond laser-assisted lenticule intrastromal keratoplasty for the correction of hyperopia].

Lenticule intrastromal keratoplasty (LIKE) was introduced clinically in the 1980s as a refractive surgery. With the advancements of femtosecond laser, LIKE has been significantly revitalized. Currently, femtosecond laser-assisted LIKE has been demonstrated to be a safe and effective surgical procedure to correct hyperopia, but the predictability is still a major limitation.

Neuropeptide FF prevented histamine- or chloroquine-induced acute itch behavior through non-NPFF receptors mechanism in male mice.

The neuropeptide FF (NPFF) system regulates various physiological and pharmacological functions, particularly pain modulation. However, the modulatory effect of NPFF system on itch remains unclear. To investigate the modulatory effect and functional mechanism induced by NPFF system on acute itch, we examined the effects of supraspinal administration of NPFF and related peptides on acute itch induced by intradermal (i.
