Visual detection of Coxsackievirus A6 using a reverse transcription polymerase spiral reaction method

Frontiers in Cellular and Infection Microbiology
Coxsackievirus A6 (CVA6) ranks as a primary enterovirus associated with hand-foot-mouth disease (HFMD) and herpangina (HA). Given its significant role in these diseases, there is an urgent need for an efficient identification method.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

The detection of visual defects in infants.

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1974
The early warning signs for the detection of visual defects in infants are emphasised. Th~ simple tests which can be carried out by the general practitioner are considered, and the more sophisticated ophthalmic investigations are discussed.S. Afr. Med. J., 48, 1261 (1974).

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Aging and visual pattern detection

Journal of Vision
A single psychophysical experiment evaluated observers' ability to detect visual patterns embedded in noise; effects of stimulus complexity and observer age were also evaluated. Eighteen younger and older observers participated in the experiment (mean ages were 20.3 and 72.6 years, respectively).
