Polymerization-Amplified Optical DNA Detection on Porous Silicon Templates. | LitMetric
A porous silicon-based optical DNA sensor is described herein, which enables rapid DNA detection. The DNA sensor relies on the specificity of the DNA base pairing in conjunction with an interferometric optical signal amplification step based on polymer formation within the porous silicon layer to detect the DNA targets in a highly selective fashion. We demonstrate that it is possible to discriminate between DNA strands exhibiting even a single nucleotide mismatch using this sensor.

Recombinant adeno-associated virus (AAV) is one of the main viral vector-based gene therapy platforms. AAV is a virus consisting of a ≈25 nm diameter capsid with a ≈4.7 kb cargo capacity.
Objective : Acute retinal necrosis (ARN) caused by varicella-zoster virus (VZV) is associated with changes in specific proteins in the eye's fluid, particularly matrix metalloproteinase-3 (MMP-3), an enzyme that breaks down tissue structures, and tissue inhibitor of metalloproteinase-1 (TIMP-1), which regulates MMP activity. This study aims to investigate how these proteins correlate with the progression of ARN.Methods : We analyzed aqueous humor samples from 33 patients with ARN and 23 control patients with virus-negative uveitis.
Avian haemosporidian parasites and avian pox virus (APV) are well-known pathogens for their impact on avian populations, especially in oceanic islands where introduced pathogens show strong virulence for endemic and naïve birds. The Bonin Islands are a group of oceanic islands 1000 km south of Tokyo. Like the Hawaiian Islands, there are many endemic and endangered species as well as introduced species, which have greatly affected the native avian fauna.
Purpose : To investigate the association between epigenetic age acceleration and glaucoma progression.Design : Retrospective cohort study.Participants : 100 primary open-angle glaucoma (POAG) patients with fast progression and 100 POAG patients with slow progression.

Background And Purpose : Tumor hypoxia is the principal cause of clinical radioresistance. Despite its established role as radiosensitizer, hydrogen peroxide (HO) encounters clinical limitations due to stability and toxicity concerns. Recent advancements in drug delivery combine HO with sodium hyaluronate (SH), enabling intratumoral administration of HO.
