The Mechanism of 540 nm Green Light in Promoting Salivary Secretion.

Although low-level laser therapy (LLLT) is a widely used noninvasive treatment because of photobiomodulation effects, its application for xerostomia remained uncertain. Tight junctions (TJs), mainly composed of claudins, occludin, and ZO family members, are crucial structures that determine material transport through paracellular pathway in salivary gland epithelial cells. This work aimed to investigate whether LLLT affected salivary secretion through epithelial TJs.

Maintaining calcium homeostasis as a strategy to alleviate nephrotoxicity caused by evodiamine.

Evodiamine (EVO), the main active alkaloid in Evodia rutaecarpa, was shown to exert various pharmacological activities, especially anti-tumor. Currently, it is considered a potential anti-cancer drug due to its excellent anti-tumor activity, which unfortunately has adverse reactions, such as the risk of liver and kidney injury, when Evodia rutaecarpa containing EVO is used clinically. In the present study, we aim to clarify the potential toxic target organs and toxicity mechanism of EVO, an active monomer in Evodia rutaecarpa, and to develop mitigation strategies for its toxicity mechanism.

Harnessing TME depicted by histological images to improve cancer prognosis through a deep learning system.

Spatial transcriptomics (ST) provides insights into the tumor microenvironment (TME), which is closely associated with cancer prognosis, but ST has limited clinical availability. In this study, we provide a powerful deep learning system to augment TME information based on histological images for patients without ST data, thereby empowering precise cancer prognosis. The system provides two connections to bridge existing gaps.

Graph neural networks (GNNs) have become a popular choice for analyzing graph data in the last few years, and characterizing their expressiveness has become an active area of research. One popular measure of expressiveness is the number of linear regions in neural networks with piecewise linear activations. In this paper, we present estimates for the number of linear regions in classic graph convolutional networks (GCNs) with one layer and multiple-layer scenarios and ReLU activation function.

[Protective effect of ophiopogonin D against isoproterenol-induced cardiomyocyte injury and targets].

This study aims to unveil the effect of ophiopogonin D(OPD) on isoproterenol(ISO)-induced apoptosis of rat cardiomyocytes and the possible targets, which is expected to provide clues for further research on the myocardial protection of ophiopogonins. Cell count kit-8(CCK-8) assay was used to detect viability of cells treated with OPD and ISO, Western blot to examine the effect of OPD and ISO on the expression of endoplasmic reticulum stress-related Bip, Bax, Perk, ATF4, caspase-12, and CHOP, flow cytometry to determine cell apoptosis rate, and Hoechst 33258 and Tunel staining to observe cell apoptosis and morphological changes. In addition, the probe for calcium ion-specific detection was employed to investigate calcium ion release from the endoplasmic reticulum, and OPD-bond epoxy-activated agarose solid-phase microspheres were prepared and used as affinity matrix to capture OPD-binding target proteins in H9 c2 cell lysate.

Embedding graphs on Grassmann manifold.

Learning efficient graph representation is the key to favorably addressing downstream tasks on graphs, such as node or graph property prediction. Given the non-Euclidean structural property of graphs, preserving the original graph data's similarity relationship in the embedded space needs specific tools and a similarity metric. This paper develops a new graph representation learning scheme, namely Egg, which embeds approximated second-order graph characteristics into a Grassmann manifold.

Responsive Hydrogels Based on Triggered Click Reactions for Liver Cancer.

Globally, liver cancer, which is one of the major cancers worldwide, has attracted the growing attention of technological researchers for its high mortality and limited treatment options. Hydrogels are soft 3D network materials containing a large number of hydrophilic monomers. By adding moieties such as nitrobenzyl groups to the network structure of a cross-linked nanocomposite hydrogel, the click reaction improves drug-release efficiency in vivo, which improves the survival rate and prolongs the survival time of liver cancer patients.

Emodin-Induced Oxidative Inhibition of Mitochondrial Function Assists BiP/IRE1/CHOP Signaling-Mediated ER-Related Apoptosis.

Cassiae Semen is a widely used herbal medicine and a popular edible variety in many dietary or health beverage. Emerging evidence disclosed that improper administration of Cassiae Semen could induce obvious liver injury, which is possibly attributed to emodin, one of the bioactive anthraquinone compounds in Cassiae Semen, which caused hepatotoxicity, but the underlying mechanisms are not completely understood. Hence, the present study firstly explored the possible role of oxidative stress-mediated mitochondrial dysfunction and ER stress in emodin-cause apoptosis of L02 cells, aiming to elaborate possible toxic mechanisms involved in emodin-induced hepatotoxicity.
