Singlet Oxygen in Food: A Review on Its Formation, Oxidative Damages, Quenchers, and Applications in Preservation.

Singlet oxygen (O) has been proven to simultaneously cause oxidative damage to food and the death of microorganisms. In order to enhance the utilization of O in food systems, this review presents an overview of recent studies on the formation mechanisms of O, the damage mechanisms of O on food, the self-protective mechanisms in food against O, and the applications of O in food preservation based on the narrative review guidelines. Studies have shown that in vegetable and meat systems, O is mainly produced through photochemical reactions.

Acoustic Motor Cortex Stimulation Enhances the Descending Analgesic Pathway to Alleviate Chronic Pain in Mice.

Chronic pain poses considerable health risks, necessitating the development of effective treatments. Physical modulation of the motor cortex has demonstrated promise for pain relief; however, existing methods require invasive electrode implantation or have limited spatial resolution. Therefore, we developed a non-invasive, high-precision acoustic motor cortex stimulation (aMCS) system to alleviate chronic pain and explore its mechanisms.

Roles of ROS in physiological, microbial and metabolomic alterations of fresh-cut sugarcane under red and blue light irradiation.

Effects of red and blue light treatment on physiological quality, microbial loads, redox status and metabolomics profiles of fresh-cut sugarcane in vacuum and plastic packages were investigated during 15 d storage.

Light treatment was beneficial to O generation, but had opposite effects on O , HO and malondialdehyde.

To evaluate effects of Lactobacillus plantarum (LW) supplementation on broiler chicken, we conducted comprehensive multi-omics analysis, growth performance evaluation, RT-qPCR analysis, and immunofluorescence.

Spatiotemporal Distributions of Acoustic Propagation in Skull During Ultrasound Neuromodulation.

There is widespread interest and concern about the evidence and hypothesis that the auditory system is involved in ultrasound neuromodulation. We have addressed this problem by performing acoustic shear wave simulations in mouse skull and behavioral experiments in deaf mice. The simulation results showed that shear waves propagating along the skull did not reach sufficient acoustic pressure in the auditory cortex to modulate neurons.
