Photoelectrocatalysis offers a powerful method for driving organic transformations by combining light and electrical energy to access more extreme potentials to generate reactive intermediates under milder conditions. Herein, we report the first application of a metal halide perovskite photoelectrocatalytic system for C-(sp)-H activation, leading to C-C and C-N bond formation via alkylation. A lead-free, alloyed double perovskite, CsAgNaBiBr, was engineered as a relatively stable photoanode and used catalytically (0.

Neuroinflammation is vital in depression's onset and development, making its relief a key treatment goal. Orientin (ORI), a natural flavonoid, is known to modulate inflammation, but whether it can ease depression by regulating neuro-inflammation remains uncertain. This study aimed to uncover ORI's antineuroinflammation mechanisms for treating depression.

Oxidative stress and mitochondrial dysfunction are recognized as pivotal factors in PD progression. Gentiopicroside (GPS), a secoiridoid derived from Gentiana manshurica Kitagawa, exhibits antioxidant and mitophagy induction properties.

We hypothesize that poor-prognosis stage I patients may exhibit key molecular characteristics deviating from AIS/MIA. Therefore, we tried to reveal molecularly and prognostically distinct subtypes of stage I LUAD by applying key molecular alterations from AIS/MIA to invasive LUAD progression.

Visual Imagery (VI) can be defined as the manipulation of visual information derived from memory rather than perception. Currently, the brain responses underlying imitation and associative VI are not clear. In this study, we explore the differences from imitation to associative VI on the brain responses based on EEG signals.

The emerging neurorehabilitation technology, Brain-Computer Interface (BCI), provides a novel prospect for stroke recovery. However, decoding brain activity during the movement present substantial challenges, and feature extraction is crutial to build a better decoder. In this study the CEBRA method were employed to extract features first based on electroencephalogram(EEG) data during Motor Execution(ME) and Motor lmagery (Ml) tasks for 20 participants (including 10 stroke patients).

Life-cycle assessment (LCA) is one of the most widely applied methods for sustainability assessment. A main application of LCA is to compare alternative products to identify and promote those that are more environmentally friendly. Such comparative LCA studies often rest on, explicitly or implicitly, an idealized assumption, namely, 1:1 displacement between functionally equivalent products.

Purpose: This study aimed to explore the impact of chronic PM exposure on intestinal barrier integrity and to uncover the underlying molecular mechanisms.
Methods: C57BL/6 J mice were exposed to either concentrated ambient PM (CPM) or filtered air (FA) for six months to simulate urban pollution conditions.
Background: Depression accounts for a high proportion of neuropsychiatric disorders and is associated with abnormal states of neurons in specific brain regions. Microglia play a pivotal role in the inflammatory state during depression development; however, the exact mechanism underlying chronic mood states remains unknown. Thus, the present study aimed to determine whether microRNAs (miRNAs) alleviate stress-induced depression-like behavior in mice by regulating the expression levels of their target genes, explore the role of neuroinflammation induced by microglial activation in the pathogenesis and progression of depression, and determine whether the role of the miR-29a-5p/transmembrane protein 33 (TMEM33) axis.

If the presence of rNMP in DNA cannot be controlled, it can lead to genome instability. The actual regulatory functions of rNMPs in DNA remain mainly unknown.
