DNA Tetrahedron Reformative Lateral Flow Assay for Improved Detection Sensitivity and Anti-Interference.
Langmuir

School of Chemistry and Chemical Engineering, Shandong University, Jinan 250100, China.
The lateral flow assay is a strip-based analytical method for the portable and convenient detection of analytes of interest. It has the advantages of visual observation, autonomous sample flow, fast coloration time, minimal tedious operation procedures, and reliance on specialized instruments. However, the rough surface of the nitrocellulose membrane renders it difficult for the immobilized nucleic acids to remain in an ordered arrangement, and the immobilized nucleic acids are also liable to be digested in a complex matrix, inducing limited sensitivity and anti-interference.

Type II nuclear receptors (T2NRs) require heterodimerization with a common partner, the retinoid X receptor (RXR), to bind cognate DNA recognition sites in chromatin. Based on previous biochemical and overexpression studies, binding of T2NRs to chromatin is proposed to be regulated by competition for a limiting pool of the core RXR subunit. However, this mechanism has not yet been tested for endogenous proteins in live cells.

Molecular beacon (MB) probes have been extensively used for nucleic acid analysis. However, MB probes fail to hybridize with folded DNA or RNA. Here, we demonstrate that MB probes equipped with extra sequences complementary to the analyte, named 'tail', can increase the signal-to-background ratio by ∼40-fold and hybridization rates by ∼800-fold compared to conventional MB probes.

January 2025
School of Medicine and Dentistry, Gold Coast Campus, Griffith University, Southport, QLD, 4222, Australia.
Background: Epstein-Barr virus (EBV) is implicated as a necessary factor in the development of multiple sclerosis (MS) and may also be a driver of disease activity. Although it is not clear whether ongoing viral replication is the driver for MS pathology, MS researchers have considered the prospect of using drugs with potential efficacy against EBV in the treatment of MS. We have undertaken scientific and lived experience expert panel reviews to shortlist existing licensed therapies that could be used in later-stage clinical trials in MS.

Background: Brain intraparenchymal schwannoma is a rare clinical entity, generally curable with adequate resection.
Methods And Results: We describe a case in a male patient first presenting at 19 months of age, the youngest reported age for this lesion. It also appears to be the first case connected to a germline TSC2 p.
