Analysis of Reactive Oxygen Species–Induced Cellular Damage in Cervical Cancer

Current Protocols, Volume 6, Issue 3, March 2026.
Abstract Reactive oxygen species (ROS) are highly reactive oxygen‐based molecules comprising hydrogen peroxide, hydroxyl radicals, superoxide anion, and singlet oxygen. These species are produced intracellularly and play an important role in cellular signaling and metabolism. Their high reactivity damages intracellular macromolecules such as lipids and

Single‐Cell Profiling of Splenic Immune Ageing and Chronic Stress Adaptations in Mice With Natural Microbiota

European Journal of Immunology, Volume 56, Issue 3, March 2026.
Mice with natural microbiota show expected ageing spleen trends: naïve T cell loss with effector‐memory expansion, mature B cell shifts, Gzmk+ CD8+ T cell heterogeneity, diminished NK cytotoxicity and pro‐inflammatory macrophages. Chronic stress modestly counteracted these age‐related changes.

Total triiodothyronine by fluorescence polarization immunoassay (FPIA)

Journal of Clinical Laboratory Analysis, 1988
AbstractA semiautomated fluorescence polarization immunoassay (FPIA) for total T3 performed using the TDx analyzer has been evaluated. Precision of the assay at a low level of T3 (<1.0 ng/mL) is not good with CVs of about 17% observed. Precision at moderate to high levels (1.7–5.6 ng/mL) is good (CVs = 11.3−4.1%). Low end imprecision is attributable

IGFBP4 is a Metric for Primary Biliary Cholangitis and Attenuates Biliary Epithelial Cell Injury

Liver International, Volume 46, Issue 3, March 2026.
ABSTRACT Background and Aims Immune‐mediated bile duct injury is the primary histological feature of autoimmune cholestatic liver diseases. Macrophages, the most abundant immune cell population in the liver, have been postulated to play a critical role in biliary repair. However, it is unclear whether activated macrophages interact with injured biliary
