A theoretical study on the mechanism and rate constants of luteolin and selenium dioxide.

Context: This study investigates the reaction mechanism of luteolin with selenium dioxide in ethanol. Through a detailed search for transition states and thermodynamic energy calculations, it was found that the reaction proceeds via two possible pathways, leading to the formation of products P1 and P2, respectively. A common feature of both pathways is that the first elementary step results in the formation of the intermediate INT1.

Design, modeling, and control of coaxial integrated macro-micro composite actuator with high-precision and long-stroke.

This paper presents a coaxial integrated macro-micro composite actuator. The macro-actuator of the macro-micro composite actuator is similar to a moving coil type voice coil motor, and a giant magnetostrictive actuator is installed coaxially inside it as a micro-actuator. In this work, kinetic models are established for both the macro-actuator and micro-actuator, and based on the models, an automatic disturbance rejection controller is adopted to control the macro-actuator, and a fuzzy sliding mode controller is adopted for the micro-actuator.

A high-resolution view of the immune and stromal cell response to infection in human volunteers.

causes the genital ulcer disease chancroid and cutaneous ulcers in children. To study its pathogenesis, we developed a human challenge model in which we infect the skin on the upper arm of human volunteers with to the pustular stage of disease. The model has been used to define lesional architecture, describe the immune infiltrate into the infected sites using flow cytometry, and explore the molecular basis of the immune response using bulk RNA-seq.

Activating Transcription Factor 5 Promotes Tumorigenic Capability in Cervical Cancer Through the Wnt/β-Catenin Signaling Pathway.

Purpose: Cervical cancer is the fourth leading cause of cancer-related death in women. Furthermore, owing to its significant risk of recurrence or metastasis, the overall prognosis of patients with cervical cancer remains poor. Activating transcription factor 5 (ATF5) plays a crucial role in cell proliferation, survival, and apoptosis, and has been implicated in the progression of various types of cancer.

Identification of the AHP family reveals their critical response to cytokinin regulation during adventitious root formation in apple rootstock.

Adventitious root (AR) formation is a bottleneck for vegetative proliferation. In this study, 13 AHP genes (MdAHPs) were identified in the apple genome. Phylogenetic analysis grouped them into 3 clusters (I, II, III), with 4, 4, and 5 genes respectively.
