The 3C-like protease (3CLpro) of SARS-CoV-2 is a crucial target for antiviral drugs due to its essential role in viral polyprotein processing. In this study, we designed and produced a modular fluorescent recombinant substrate (6×His-ECFP-AVLQSGFRK-EYFP), which was then immobilized on Ni-NTA magnetic beads (Ni-NTA-6×His-ECFP-AVLQSGFRK-EYFP) for the assay of 3CLpro activity. Upon cleavage at the specific AVLQ↓SG motif, the EYFP fragment was released into the supernatant and quantified via fluorescence measurement (Ex/Em = 480/528 nm).

Background: Telomere length (TL) is a valuable marker of aging and stress that reflects both genetic and environmental influences. Quantitative PCR (qPCR) TL measurement is a powerful and cost-effective assay, especially in population studies with limited quantities of source material. Nevertheless, collecting and transporting high-quality blood samples can be logistically challenging, and research suggests that several preanalytical and analytical factors can influence the reliability and precision of the qPCR assay.

Objective: To measure and compare CSF cytokine concentrations among horses with equine neuroaxonal dystrophy (eNAD)/equine degenerative myeloencephalopathy (EDM), horses with cervical vertebral stenotic myelopathy (CVSM), and control horses and to evaluate for associations with clinical parameters.

Methods: Banked equine CSF samples from horses with neurologic disease that underwent a complete neurologic examination and postmortem diagnosis confirmation of CVSM or eNAD/EDM or from control horses were included. Cytokines were measured with an equine-specific cytokine/chemokine magnetic bead multiplex panel (23-cytokine multiplex).

Single-phase dysprosium orthoferrite (DyFeO: DFO) nanoparticles have been synthesized using the nanoagitator bead mill. Rietveld refinement of the experimental X-ray diffraction (XRD) pattern confirms the orthorhombic crystal symmetry ( space group) of the material. The surface morphology, grain size distribution, and color mapping were analyzed.

Colorectal cancer (CRC) is associated with high morbidity and mortality rates worldwide. Therefore, early diagnosis and treatment are of great significance for improving the survival rate of CRC patients. Herein, we performed subtractive cell-SELEX using two cell lines (LS174T and CL187) with the same genetic background but different malignant potentials for the target and negative cells.
