Diquat exacerbates oxidative stress and neuroinflammation by blocking the autophagic flux of microglia in the hippocampus.

Diquat (DQ) is a widely utilized nonselective herbicide that is primarily used to control a wide range of weeds and crop residues. It also has significant environmental implications. DQ exposure can cause severe damage to the central nervous system (CNS), a critical symptom of acute poisoning that endangers patients.

The clinical trajectory of peripheral blood immune cell subsets, T-cell activation, and cytokines in septic patients.

Objective And Design: Changes in the immune status of patients with sepsis may have a major impact on their prognosis. Our research focused on changes in various immune cell subsets and T-cell activation during the progression of sepsis.

Methods And Subjects: We collected data from 188 sepsis patients at the First Affiliated Hospital of Zhejiang University School of Medicine.

Mechanistic insights into photoinduced energy and charge transfer dynamics between magnesium-centered tetrapyrroles and carbon nanotubes.

Functionalizing single-walled carbon nanotubes (SWNTs) with light-harvesting molecules is a facile way to construct donor-acceptor nanoarchitectures with intriguing optoelectronic properties. Magnesium-centered bacteriochlorin (MgBC), chlorin (MgC), and porphyrin (MgP) are a series of tetrapyrrole macrocycles comprising a central metal and four coordinated aromatic or antiaromatic five-membered rings linked by methine units, which show excellent visible light absorption. To delineate the effects of the aromaticity of coordinated rings on the optoelectronic properties of the nanocomposites, the photoinduced energy and charge transfer dynamics between Mg-centered tetrapyrroles and SWNTs are explored.

Analysis of Structure and Antioxidant Activity of Polysaccharides from .

We extracted, purified, and characterized three neutral and three acidic polysaccharides from the roots, stems, and leaves of Kitigawa. The results of the analysis of monosaccharide composition indicated that the polysaccharides from the roots and stems were more similar to each other than they were to the polysaccharides from the leaves. The in vitro antioxidant results demonstrated that the acidic polysaccharides had stronger antioxidant activity than the neutral fractions.

Fault diagnosis for three-phase PWM rectifier based on deep feedforward network with transient synthetic features.

Three-phase PWM rectifiers are adopted extensively in industry because of their excellent properties and potential advantages. However, while the IGBT has an open-circuit fault, the system does not crash suddenly, the performance will be reduced for instance voltages fluctuation and current harmonics. A fault diagnosis method based on deep feedforward network with transient synthetic features is proposed to reduce the dependence on the fault mathematical models in this paper, which mainly uses the transient phase current to train the deep feedforward network classifier.
