Environment International, Год журнала: 2023, Номер 182, С. 108285 - 108285

Опубликована: Ноя. 2, 2023

Water scarcity, one of the most pressing challenges we face today, has developed for many reasons, including increasing number waterborne pollutants that affect safety water environment. Waterborne human, animal and plant viruses represent huge health, environmental, financial burden thus it is important to efficiently inactivate them. Therefore, main objective this study was construct a unique device combining plasma with supercavitation evaluate its efficiency decontamination emphasis on inactivation viruses. High (>5 log10 PFU/mL) bacteriophage MS2, human enteric virus surrogate, achieved after treatment 0.43 L recirculating up 4 min. The key factors in were short-lived reactive species damaged viral RNA. treated short time required successful did not cause cytotoxic effects vitro HepG2 cell model system or adverse potato physiology. combined plasma-supercavitation represents an environmentally-friendly technology could provide contamination-free safe water.

Numerical investigation of acoustic cavitation and viscoelastic tissue deformation

Ultrasonics Sonochemistry, Год журнала: 2024, Номер 102, С. 106757 - 106757

Опубликована: Янв. 1, 2024

Acoustic cavitation and tissue deformation are studied by modifying a level-set method for compressible two-phase flows to consider viscoelastic deformation. The numerical simulations performed using different shear moduli bubble-tissue distances demonstrate various interactions between bubble tissue, including inverted cone-shape bubbles, migration, liquid jet formation, compressive expansive deformation, perforation. is observed grow larger with increasing bulk modulus density. maximum generally increases decreasing initial distance conditions that maximize in the range of 1-10MPa, unless density very large.

Nucleic acid amplification testing facilitates the detection of disease through specific genomic sequences and is attractive for point-of-need (PONT); in particular, early microorganisms can alert response systems to protect public ecosystems from widespread outbreaks biological threats, including infectious diseases. Prior nucleic detection, extensive sample preparation techniques are required free acids extract them matrix. Sample critical maximize sensitivity reliability testing. As enzymatic reactions be sensitive inhibitors sample, as well chemicals used lysis extraction, avoiding inhibition a significant challenge, particularly when minimising liquid handling steps also desirable translation assay portable format PONT. The reagents testing, covering NA extraction (binding, washing, elution), reviewed with focus on their suitability use

Virus inactivation by matching the vibrational resonance

Applied Physics Reviews, Год журнала: 2024, Номер 11(2)

Опубликована: Май 30, 2024

Physical approaches based on irradiation provide advances for the prevention and treatment of viral infections, while recognizing that certain chemical inactivation techniques demonstrate significant effectiveness alongside physical methods. By generating resonant vibrations complete virus particles, which are in GHz range quite high compared to human cells, viruses can be inactivated. Therefore, exposure ultrasound waves or non-thermal microwaves with a suitable frequency oscillating electric field holds potential neutralize particle no damage human. The deactivation mechanism could result mechanical effect oxidation stress, this article, we discuss elucidation these effects virus' structure. We also explore current state future prospects anti-viral methods acoustic cavitation via microwave, addressing critical needs virology.

Inactivation of MS-2 virus in water by rotational generator of hydraulic shock

Heliyon, Год журнала: 2024, Номер 10(21), С. e39795 - e39795

Опубликована: Окт. 25, 2024

This study investigates the effect of hydraulic shock waves on inactivation MS-2 bacteriophage, a norovirus surrogate. A falling circular jet water spiked with (∼1000 PFU/mL) was repeatedly impacted by rotating blade, resulting in occurrence within liquid region adjacent to impact. The proof-of-concept rotational generator treating 9 L viruses able achieve 3 logs reduction viral plaque count 80-100 passes at moderate blade impact velocities (namely, 70 and 88 m/s) despite temperature not exceeding 40 °C no detectible cavitation. Within first 20 passes, most capsid proteins were degraded, their concentration reduced from 22 μg/mL only 7.3 μg/mL. Due lack further protein destruction, additional subsequent 80 is indicative damage inflicted recognition receptors. All this suggests that shockwaves amplitude (few tens MPa) alone are sufficient for effective inactivation. Considering device's good scalability potential, generators could prove virus-contaminated waters.
