Unveiling the photocatalytic and antimicrobial activities of star-shaped gold nanoparticles under visible spectrum.
Sci Rep
January 2025
School of Chemical engineering, Military Technical College, Cairo, Egypt.
This study reports on the facile development of star-shaped gold nanoparticles via seed-mediated growth protocol. Gold nanostars (AuNSTs) demonstrated average particle size of 48 nm using transmission electron microscopy (TEM). Chemical composition of AuNSTs was verifired using energy dispersive X-ray spectroscopy (EDX) mapping.

Electronic waste (e-waste) has become a significant environmental concern worldwide due to the rapid advancement of technology and short product lifecycles. Waste-printed electronic boards (WPCBs) contain valuable metals and semiconductors; among them, tin can be recycled and repurposed for sustainable material production. This study presents a potential ecofriendly methodology for the recovery of tin from WPCBs in the form of tin oxide nanostructured powders.

Purpose: The aim of the present study was to establish a SYBR Green-based real-time PCR assay for detection of the Nc5 segment from the Neospora caninum genome.
Methods: The oligonucleotides sequences targeting the Nc5 gene previously reported and designed in-house were validated. Two Primer sets were evaluated and tested in four different combinations.
Exploring the dynamics of T-cell responses: a combined approach using EdU incorporation and proliferation dye dilution assay.
Immunol Cell Biol
December 2024
R&D, Sanquin Diagnostic Services, Amsterdam, The Netherlands.
Understanding antigen-specific T-cell responses is crucial for advancing immunotherapies and vaccine development. This study proposes a novel approach combining two complementary assays: the 5-ethynyl-2'-deoxyuridine (EdU) incorporation assay (tracking proliferation over 0-48 h) and the VPD450 dye dilution assay (tracking proliferation over 4-6 days). Integrating these techniques provides additional insights into T-cell proliferation kinetics.

October 2024
Department of Biomedical Engineering, Stevens Institute of Technology, Hoboken, New Jersey.
Objective: To investigate retinal vascular permeability mapping as a potential biomarker for diabetic retinopathy in subjects with diabetes with no signs of retinopathy and with mild nonproliferative retinopathy.
Design: This is a case-control study.
Subjects: Participants included 7 healthy controls, 22 subjects with diabetes mellitus and no clinical signs of retinopathy (DMnoDR), and 7 subjects with mild nonproliferative diabetic retinopathy (NPDR).
