Resumen de: US20260118323A1
A method for determining multi-characteristic components of ASDZW is provided. By optimizing the gradient elution program of high performance liquid chromatography (HPLC), strictly controlling the initial mobile phase ratio of the gradient elution program, cooperating with the selections of the chromatographic column and the mobile phase, the invention finally realizes the simultaneous, rapid and comprehensive determination of six characteristic components in ASDZW under the condition of a single wavelength; specifically, the six characteristic components are polygalaxanthone III, 3,6′-disinapoyl sucrose, ginseng saponin Rb1, β-asarone, dehydrotumulosic acid, and pachymic acid. The whole detection process is a single wavelength detection with high detection efficiency and short analysis time, and the detection limits of the six components are lower than 0.008 μg/mL, meaning this method has high sensitivity, good specificity, accurate results, and good reproducibility.

The present invention provides a multiomics approach, which integrate single-cell RNA-sequencing (scRNA-seq) and spatiotemporal transcriptomics (ST) offering potential for dissecting transcriptional networks and revealing cell-cell interactions involved in biomolecular pathomechanisms. The present invention also provides a multimodal approach combining high-throughput scRNA-seq and ST to elucidate XLRS-specific transcriptomic signatures in two XLRS-like models with retinal splitting phenotypes, including genetically engineered (Rs1emR209C) mice and patient-derived retinal organoids harboring the same patient-specific p.R209C mutation. Through multiomics transcriptomic analysis, the endoplasmic reticulum (ER) stress/eIF2 signaling, mTOR pathway, and the regulation of eIF4 and p70S6K pathways as chronically enriched and highly conserved disease pathways between two XLRS-like models are identified. Western blots and proteomics analysis validated the occurrence of unfolded protein responses, chronic eIF2α signaling activation, and chronic ER stress-induced apoptosis. Furthermore, therapeutic targeting of the chronic ER stress/eIF2α pathway activation synergistically enhanced the efficacy of AAV mediated RS1 gene delivery, ultimately improving bipolar cell integrity, postsynaptic transmission, disorganized retinal architecture and electrophysiological responses. Collectively, the complex transcriptomic signatures obtained from Rs1emR209C mice and patient-derived retinal organoid

Resumen de: WO2026084162A1
The present invention relates to a method for controlling the length of amyloid fibrils through a pressurized cutting process. Specifically, according to the present invention, long amyloid fibrils having a relatively long length can be uniformly cut into a desired specific length, and thus fibrils having a predetermined length can be produced precisely and reproducibly, thereby enabling cytotoxicity analysis according to the length of amyloid fibrils in neurodegenerative disease research. In addition, amyloid fibrils according to the present invention consistently maintain electrical properties, mechanical properties, and chemical reactivity due to the uniform and consistent length thereof, and thus may be suitable for commercial applications. In addition, since the pressurized cutting process of the present invention is relatively simple and economical, the commercial potential of various products and services using amyloid fibrils can be increased. Therefore, the pressurized cutting process is highly likely to be used in various technical fields such as neurodegenerative disease research, biosensors, filtration systems, nano-electronic devices, nanoparticles for drug screening, and bioadhesives.
