Exploring the decentralized treatment of sulfamethoxazole-contained poultry wastewater through vertical-flow multi-soil-layering systems in rural communities.

Author(s): Song P, Huang G, An C, Xin X, Zhang P, Chen X, Ren S, Xu Z, Yang X

Sulfamethoxazole (SMX) is the most widely distributed sulfonamide antibiotics detected in decentralized poultry wastewater in rural communities. As an economically-feasible and eco-friendly technology for decentralized wastewater treatment in rural areas, v...

Abstract

Acoustically driven gas bubble cavitation locally concentrates energy and can result in physical phenomena including sonoluminescence and erosion. In biomedicine, ultrasound-driven microbubbles transiently increase plasma membrane permeability (sonoporation) to promote drug/gene delivery. Despite its potential, little is known about cellular response in the aftermath of sonoporation. In the work described here, using a live-cell approach, we assessed the real-time interplay between transendothelial perforations (~30-60 s) up to 650 µm2, calcium influx, breaching of the local cytoskeleton and sonoporation resealing upon F-actin recruitment to the perforation site (~5-10 min). Through biophysical modeling, we established the critical role of membrane line tension in perforation resealing velocity (10-30 nm/s). Membrane budding/shedding post-sonoporation was observed on complete perforation closure, yet successful pore repair does not mark the end of sonoporation: protracted cell mobility from 8 µs of ultrasound is observed up to 4 h post-treatment. Taken holistically, we established the biophysical context of endothelial sonoporation repair with application in drug/gene delivery.
