Detection of Mycobacterium avium subsp. paratuberculosis in Bovine Faeces Using a Rhodamine B Hydrazone Immunosensor on Antibody‐Coated Nitrocellulose Membranes

open access: yesVeterinary Medicine and Science, Volume 12, Issue 6, November 2026.
A rhodamine B hydrazone nanoparticle‐based immunosensor coupled with an antibody‐coated nitrocellulose membrane (IMS‐CNM) was developed for rapid detection of Mycobacterium avium subsp. paratuberculosis (MAP) in bovine faeces. The assay combines antibody‐mediated bacterial capture with chromogenic nanoparticle detection, providing a simple, rapid and ...

Assessing CD8+ T cell cross‐reactivity to influenza A, B and C virus‐derived peptides presented by HLA‐B*18:01

open access: yesClinical &Translational Immunology, Volume 15, Issue 10, 2026.
Abstract Objectives Despite the availability of vaccines, influenza viruses still cause substantial morbidity and mortality. This highlights the need for improved vaccines and novel therapeutics. CD8+ T cells recognise conserved viral epitopes and can provide broad protection, making them attractive targets for next‐generation vaccine design.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, Volume 600, Issue 17, Page 2564-2578, September 2026.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

A Phase‐Resolved Geometric Deep Learning Framework Maps Structural Determinants of Disease‐Associated Protein Aggregation and Guides Suppressor Design

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
SKALE 2.0 maps disease‐associated protein aggregation as a phase‐resolved structural process, linking mutation‐induced geometric perturbations to nucleation, elongation, and suppressor design. Across neurodegenerative proteins, the framework reveals cryptic aggregation vulnerabilities, separates phase‐concordant and phase‐switching mutations, and ...

Proteinaceous Protease Inhibitor from : Purification, Characterization and Antibacterial Activity

open access: yesNatural Product Communications, 2013
A thermo-stable, proteinaceous protease inhibitor (LPI) from Lawsonia inermis is reported. The LPI was purified from Lawsonia inermis seeds by subsequent ammonium sulfate precipitation, ion exchange chromatography (DEAE-Cellulose) and gel permeation ...
