The search for the signature of nonthermal (so-called "hot") electrons in illuminated plasmonic nanostructures requires detailed understanding of the nonequilibrium electron distribution under illumination, as well as a careful design of the experimental system employed to distinguish nonthermal electrons from thermal ones. Here, we provide a theory for using plasmonic molecular junctions to achieve this goal. We show how nonthermal electrons can be measured directly and separately from the unavoidable thermal response and discuss the relevance of our theory to recent experiments.

Cellular senescence contributes to inflammation and organ dysfunction during aging. While this process is generally characterized by irreversible cell cycle arrest, its morphological features and functional impacts vary in different cells from various organs. In this study, we examined the expression of multiple senescent markers in the lungs of young and aged humans and mice, as well as in mouse lung endothelial cells cultured with a senescence inducer, suberoylanilide hydroxamic acid (SAHA), or doxorubicin (DOXO).

Introduction: In the environment, mycotoxins and fungicides frequently coexist, potentially causing synergistic risks to organisms. Epoxiconazole (EPO) and aflatoxin B1 (AFB1) are a common fungicide and mycotoxins, respectively, which are widely present in the environment and have toxic effects on multiple organs once entering the organism, but it is still unclear whether the co-exposure has a synergistic toxic effect.
Objectives: This study delves into the molecular mechanisms underlying the co-exposure to EPO and AFB1, emphasizing multi-organ toxicity in female zebrafish (F0 generation) and potential transgenerational impacts on the offspring embryos (F1 generation) through multi-omics approaches.
Diversity of TCR repertoire predicts recurrence after CRT followed by durvalumab in patients with NSCLC.

Chemoradiotherapy (CRT) followed by durvalumab is standard for unresectable locally advanced non-small-cell lung cancer (LA-NSCLC). This study assesses how CRT alters the T-cell receptor (TCR) repertoire in CD8 + PD-1 + T-cells and its impact on clinical outcomes. This prospective study, conducted from November 2019 to May 2021 at three institutions in Japan, evaluated the diversity of TCR repertoire (DE50) in PD-1 + CD8 + T-cells and CD8 + T-cell phenotypes in peripheral blood before and after CRT.

Materials exhibiting both metallic and semiconducting states, including two-dimensional transition metal dichalcogenides (TMDs), have numerous applications. We therefore investigate the effects of axial and shear strains on the phase energetics of pristine and striped TMDs using density functional theory and classical molecular dynamics simulations. We demonstrate that control of the phase distribution can be achieved by the integration of strain engineering and Kirigami techniques.

Background: Although mice are used extensively to study atherosclerosis of different vascular beds, limited data is published on the occurrence of intracranial atherosclerosis. Since intracranial atherosclerosis is a common cause of stroke and is associated with dementia, a relevant animal model is needed to study these diseases.
Methods And Results: We examined the presence of intracranial atherosclerosis in different atherogenic mouse strains and studied differences in vessel wall characteristics in mouse and human tissue in search for possible explanations for the different atherosclerotic susceptibility between extracranial and intracranial vessels.
