Biomarkers.

Background: Alzheimer's disease (AD) is a neurodegenerative disorder that is characterized by progressive cognitive decline. Early detection of AD is essential for timely intervention and treatment. The objective of this study is to explore the potential usefulness of virtual reality (VR) tasks combined with frontal EEG recordings for early detection of cognitive impairment in individuals with SCD (subject cognitive decline), MCI (mild cognitive impairment), and AD (Alzheimer's disease).

M13KO7 bacteriophage enables Potato Virus Y detection.

In this study, we confirmed the binding of M13KO7 to (PVY) using enzyme-linked immunosorbent assay. M13KO7 is a "bald" bacteriophage in which no recombinant antibody is displayed. M13KO7 is easy to propagate by using , making this method more reasonable in economic perspective.

Distribution of Species Isolated in South Korea and Comparison of Temperature Effects on Pathogenicity.

, which causes soft rot disease, is divided into 18 species based on the current classification. A total of 225 strains were isolated from 10 main cultivation regions of potato (), napa cabbage ( subsp. ), and radish () in South Korea; 202 isolates (90%) were from potato, 18 from napa cabbage, and five from radish.

Development of novel detection system for sweet potato leaf curl virus using recombinant scFv.

Sweet potato leaf curl virus (SPLCV) causes yield losses in sweet potato cultivation. Diagnostic techniques such as serological detection have been developed because these plant viruses are difficult to treat. Serological assays have been used extensively with recombinant antibodies such as whole immunoglobulin or single-chain variable fragments (scFv).
