The combined effects of microplastics and their additives on mangrove system: From the sinks to the sources of carbon.

Mangrove ecosystems, a type of blue carbon ecosystems (BCEs), are vital to the global carbon cycle. However, the combined effects of microplastics (MPs) and plastic additives on carbon sequestration (CS) in mangroves remain unclear. Here, we comprehensively review the sources, occurrence, and environmental behaviors of MPs and representative plastic additives in mangrove ecosystems, including flame retardants, such as polybrominated diphenyl ethers (PBDEs), and plasticizers, such as phthalate esters (PAEs).

A study on the impact of icon structural features in human-computer interface on visual search efficiency.

This article, from the perspective of structural features, focuses on in-car user interface icons and explores the impact of different icon structural features on visual search efficiency. Initially, we categorised the icons into four groups based on structural features: individual structure icons (ISI), enclosed structure icons (ESI), horizontal structure icons (HSI) and vertical structure icons (VSI). Subsequently, we conducted a visual search experiment with structure as the sole variable, recording participants' behaviours and eye-tracking data.

This article introduces a novel emotion recognition framework, primarily targeting the analysis of users' psychological reactions and stimuli.

PDLIM7 Promotes Tumor Metastasis in Papillary Thyroid Carcinoma via Stabilizing Focal Adhesion Kinase Protein.

As an actin cytoskeleton interactor, PDZ (postsynaptic density 65-discs large-zonula occludens 1) and LIM (abnormal cell lineage 11-isket 1-mechanosensory abnormal 3) domain protein 7 (PDLIM7) was supposed to play an essential role modulating cytoskeleton. Focal adhesions (FAs), which are located at the cytomembrane terminus of actin cytoskeleton, function as a force sensor and can transform the mechanical signal to a biochemical signal. Focal adhesion kinase (FAK) localizes to and regulates signal transduction in FAs, which play an essential role in cell polarity, migration, and invasion.

Aloe-emodin targets multiple signaling pathways by blocking ubiquitin-mediated degradation of DUSP1 in nasopharyngeal carcinoma cells.

Aloe-emodin (AE) has been shown to inhibit the proliferation of several cancer cell lines, including human nasopharyngeal carcinoma (NPC) cell lines. In this study, we confirmed that AE inhibited malignant biological behaviors, including cell viability, abnormal proliferation, apoptosis, and migration of NPC cells. Western blotting analysis revealed that AE upregulated the expression of DUSP1, an endogenous inhibitor of multiple cancer-associated signaling pathways, resulting in blockage of the extracellular signal-regulated kinase (ERK)-1/2, protein kinase B (AKT), and p38-mitogen activated protein kinase（p38-MAPK） signaling pathways in NPC cell lines.

Perovskite Random Lasers, Process and Prospects.

Curcumin protects islet beta cells from streptozotocin‑induced type 2 diabetes mellitus injury via its antioxidative effects.

Streptozotocin (STZ)-induced diabetes rodent models are widely used to study the pathogenesis and metabolic function in diabetes (DM). The aim of this study was to assess the antioxidant effect of curcumin in STZ-induced type 2 diabetes mellitus (T2DM). In this research, rats were randomly divided into 3 groups (8 in each group): a nondiabetic group (Control), a diabetic group (DM), and a curcumin treatment group (DM + Cur 200 mg/kg group).

Loss of AKR1C1 is a good prognostic factor in advanced NPC cases and increases chemosensitivity to cisplatin in NPC cells.

Cisplatin resistance is one of the main obstacles in the treatment of advanced nasopharyngeal carcinoma (NPC). AKR1C1 is a member of the Aldo-keto reductase superfamily (AKRs), which converts aldehydes and ketones to their corresponding alcohols and has been reported to be involved in chemotherapeutic resistance of multiple drugs. The expression and function of AKR1C1 in NPC have not been reported until now.

Tailoring the structure of metal oxide nanostructures towards enhanced sensing properties for environmental applications.

The present article reviews recent works in our laboratory about the sensing properties to toxic gases using nanostructured WO(3), TiO(2), FTiO(2), and CuO functionalized quartz crystal microbalance (QCM) sensors. WO(3) and TiO(2) functionalized QCM sensors have much shorter response time than those functionalized by conventional hydrogen-bond acidic branched copolymers for detection of dimethyl methylphosphonate (DMMP). FTiO(2) functionalized QCM sensors can improve the gas sensing characteristics by shortening the response time but at the price of partial irreversibility.
