Kinetic processes of interfacial transport of reactive species across plasma-water interfaces: the effect of temperature.

This work quantifies, through use of molecular dynamics (MD) simulations, the kinetic rates of physical surface processes occurring at a plasma-water interface. The probabilities of adsorption, absorption, desorption and scattering were computed for O, NO, NO, NO, OH, HO, HNO, HNO, and NO as they interact with the interface at three water temperatures: 298 K, 323 K, and 348 K. Species are categorised into the short-residence group (O, NO, NO, and NO) and the long-residence group (OH, HO, HNO, HNO, and NO) based on their mean surface residence time.

Effects of implant status and breed type on feedlot performance, carcass characteristics, sera metabolites, and immunohistochemical responses in finishing steers.

The number of beef × dairy animals entering feedlots has increased, but the response of beef × dairy cattle to growth-promoting implants has not been well characterized. The objective of this study was to evaluate the effects of breed type and implant administration on live performance, carcass characteristics, sera metabolites, and immunohistochemical (IHC) outcomes. Forty-eight steers (average body weight [BW] = 417±22 kg) were sorted by breed into groups of predominantly Angus (B), black-hided beef × primarily Holstein (B×D), or Holstein (D), and half of the steers within each breed type were administered a steroidal implant.

The Burden of Recurrent Head and Neck Squamous Cell Carcinoma Across the United Kingdom: Results From a National Snapshot Study.

Background: To investigate the management of recurrent head and neck squamous cell carcinoma (rHNSCC) and describe survival outcomes.

Methods: Post hoc subgroup analysis of a retrospective national observational cohort was conducted. All patients with rHNSCC who received a definitive treatment decision between September 1, 2021 and November 30, 2021 were included.

Ferroptosis of select skin epithelial cells initiates and maintains chronic systemic immune-mediated psoriatic disease.

Dysregulations of epithelial-immune interactions frequently culminate in chronic inflammatory diseases of the skin, lungs, kidneys, and gastrointestinal tract. Yet, the intraepithelial processes which initiate and perpetuate inflammation in these organs are poorly understood. Here, by utilizing redox lipidomics we identified ferroptosis-associated peroxidation of polyunsaturated phosphatidylethanolamines in the epithelia of patients with asthma, cystic fibrosis, psoriasis and renal failure.
