Objectives: Multiplex immunohistochemistry and immunofluorescence (mIHC/IF) are emerging technologies that can be used to help define complex immunophenotypes in tissue, quantify immune cell subsets, and assess the spatial arrangement of marker expression. mIHC/IF assays require concerted efforts to optimize and validate the multiplex staining protocols prior to their application on slides. The best practice guidelines for staining and validation of mIHC/IF assays across platforms were previously published by this task force.

Metal aluminum ions and the antibiotic NOR have both benefited humanity and due to improper use, posed significant threats to the environment and human health. Although the correct and rational use of these substances is crucial, developing real-time, rapid, and highly sensitive detection of trace aluminum ions and NOR in the environment and organisms is more important for early diagnosis of potential related diseases. After several decades of development, fluorescence analysis has become a mainstream research method due to its ability to meet these requirements.

Although electrochemical biosensors have been developed to detect multiple microRNAs (miRNAs) simultaneously through loading different capture probes, high surface-induced perturbation and competition among probes have reduced the detection sensitivity. To address these challenges, a trefoil DNA capture probe (TDCP) was designed for microRNA-21 (miR-21) and microRNA-16 (miR-16) detection simultaneously. The TDCP exhibits a stable structure, low spatial resistance, and integral rigidity, which decreases high surface-induced perturbations and competition to improve the accessibility of the target miRNA.

The potential risk of chemicals to the human eye is assessed by adopted test guidelines (TGs) for regulatory purposes to ensure consumer safety. Over the past decade, the Organization for Economic Co-operation and Development (OECD) has approved new approach methodologies (NAMs) to predict chemical eye damage. However, existing NAMs remain associated with limitations: First, no full replacement of the in vivo Draize eye test due to limited predictability of severe/mild damage was reached.

Purpose: To evaluate the efficacy and safety of dexamethasone implantation in the supraciliary (SC) space, a novel and potential effective implantation site, compared to intravitreal (IV) application.
Methods: This prospective study included 39 eyes of 38 patients with macular oedema (ME) who underwent SC and IV dexamethasone implantation (SC-DEX and IV-DEX). Patients were randomly assigned to treatment groups and followed for 3 months.
