An Energy Autonomous Microneedle Array‐Based Sensing System for Continuous Biomarker Monitoring
Advanced Science, EarlyView.This work presents an innovative self‐powered wearable biosensor system for real‐time monitoring of multiple biomarkers in interstitial fluid. The device integrates stainless steel‐based minimally invasive microneedles with ion‐selective membranes, enabling simultaneous Na+, K+, Ca2+, pH, and glucose detection.

Calcium uptake, respiration, and ultrastructure of sperm exposed to ionophore A23187 [PDF]
, 1987 Calcium accumulation by ram sperm in the presence of 3.0 μM ionophore A23187 increased greatly when the pH of the medium was raised from 7.5 to 8.5. The increase in calcium uptake was remarkable between pH 7.5 and 8.0 and was paralleled by increased ...

Acta Societatis Botanicorum Poloniae, 2014 It is shown that callose synthesis in the Oenothera biennis pollen tube is regulated by the endogenous Ca2+ level. Calcium antagonists reduced the amount of callose in the wall above the tip of the pollen tube (Verapamil - calcium channels blocker) and ...

Arthritis &Rheumatology, EarlyView.Objective Carbamylation, a nonenzymatic post‐translational modification, contributes to rheumatoid arthritis (RA) pathogenesis. Anti‐carbamylated protein antibodies (anti‐CarP) occur in around 50% of patients with RA and associate with greater joint damage. Neutrophil extracellular traps (NETs) are a major source of carbamylated autoantigens. We sought

BMEMat, EarlyView.The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.
