Frog virus 3-like ranaviruses (FV3-like viruses), particularly FV3 (Frog virus 3), represent typical species within the genus Ranavirus, primarily infecting amphibians and reptiles, thereby posing serious threats to aquaculture and biodiversity conservation. We designed a pair of universal primers and a probe targeting the conserved region of the major capsid protein (MCP) genes of FV3-like viruses. By integrating recombinase-aided amplification (RAA) with lateral flow dipstick (LFD) technology and real-time fluorescence (RF) modification, we established RAA-LFD and RF-RAA assays.

Isothermal amplification-based nucleic acid detection technologies have become rapid and efficient tools for molecular diagnostics. Sequence-specific monitoring methods are crucial for isothermal amplification, as they help identify the occurrence of extended primer dimers, which can lead to false positive results. Fluorescent aptamers are promising tools for real-time monitoring of isothermal amplification but are inherently limited by thermostability.

Bovine Babesiosis, a tick-borne disease that causes major economic loss in cattle farms, is caused by Babesia species. The diagnosis of the disease is suspected through clinical features (e.g.

This paper has two concurrent goals. On one hand, we hope it will serve as a simple primer in the use of linear mixed modelling (LMM) for inferential statistical analysis of multimodal data. We describe how LMM can be easily adopted for the identification of trial-wise relationships between disparate measures and provide a brief cookbook for assessing the suitability of LMM in your analyses.

With the goal of fast and accurate diagnosis of infectious diseases, this study presents a novel electrochemical biosensor that employs a refined aptamer (C9t) for the detection of spike (S) protein SARS-CoV-2 variants in a flexible multielectrode aptasensor array with PoC capabilities. Two aptamer modifications were employed: removing the primer binding sites and including two dithiol phosphoramidite anchor molecules. Thus, reducing fabrication time from 24 to 3 h and increasing the stability and sparseness for multi-thiol aptasensors compared to a standard aptasensor using single thiols, without a reduction in aptamer density.
