Color and COD Removal From ECF Effluent by Airlift Reactor With Immobilized Lentinus edodes

open access: yesChemical Engineering &Technology, Volume 49, Issue 5, May 2026.
Airlift bioreactor treating ECF bleaching effluent with Lentinus edodes immobilized on polystyrene fibers achieved up to 48% color and 41% COD removal. Under optimized aeration (300 mL/min) and HRT (78 h) without glucose, COD removal remained stable for 15 days, supporting a low‐input, enzyme‐driven strategy for pulp‐and‐paper wastewater.

Distinct Neuronal Activation in the Paraventricular Nucleus of the Hypothalamus Accompanies Baroreflex Impairment and Elevated Cardiac Sympathetic Tone in Salt‐Loaded Rats

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 10, May 2026.
This study investigated an animal model of short‐term high‐salt exposure (2% NaCl) for 7 days and its effects on baroreflex function, cardiac autonomic balance, and the pattern of paraventricular nucleus of the hypothalamus (PVH) neuronal activation during a baroreflex loading. High salt intake leads to an increase in blood pressure (BP) and heart rate
