Hijacking the hyaluronan assisted iron endocytosis to promote the ferroptosis in anticancer photodynamic therapy.

Photodynamic therapy (PDT) eradicates tumor cells by the light-stimulated reactive oxygen species, which also induces lipid peroxidation (LPO) and subsequently ferroptosis, an iron-depended cell death. Ferroptosis has a tremendous therapeutic potential in cancer treatment, however, the ferroptosis efficiency is largely limited by the available iron in cells. Through hijacking the CD44-mediated iron endocytosis of hyaluronan (HA), here PDT with enhanced ferroptosis was realized by a HA@Ce6 nanogel self-assembled from HA, a photosensitizer Chlorin e6 (Ce6) and Fe as cross-linkers.

Interfacial engineering on hierarchical ZrO nanozyme realizes efficient CO photoreduction.

Designing and fabricating nanozymes with photoactivity for CO reduction poses a significant challenge. Here, a hierarchically structured ZFs-tpyNi heterojunction nanozyme, comprising a terpyridine-based Ni complex supported on ZrO nanoframes, has been created through an interfacial engineering strategy for efficient CO reduction under visible light. Due to its unique structural and compositional advantages, ZFs-tpyNi demonstrates superior photocatalytic CO-to-CO conversion compared to its counterpart of ZFs and tpyNi, achieving a CO yield of 18.

Brain injury in premature infants may be related to abnormal colonization of early gut microbiome.

Background: Premature infants are more prone to brain injuries owing to incomplete nervous system development and poor adaptation outside the mother's body. Without timely intervention, premature infants with brain injuries often develop intellectual disabilities, causing significant burdens on families and the society. Multiple studies have shown that gut dysbiosis can affect the nervous system, and vice versa.

Molecular identification and expression patterns of sweet cherry HIPPs and functional analysis of PavHIPP16 in cold stress.

The HIPP proteins are involved in low-temperature stress, the growth of sweet cherry, and may be potential targets for genetic improvement. PavHIPP16 improved cold resistance in Arabidopsis. In response to abiotic stressors, the heavy metal-associated isoprenylated plant protein (HIPP) proteins play a crucial regulatory role.

Predicting the Ki-67 proliferation index in cervical cancer: a preliminary comparative study of four non-Gaussian diffusion-weighted imaging models combined with histogram analysis.

Background: The prognosis for patients with cervical cancer (CC) is strongly correlated with the Ki-67 proliferation index (PI). However, the Ki-67 PI obtained through biopsy has certain limitations. The non-Gaussian distribution diffusion model of magnetic resonance imaging (MRI) may play an important role in characterizing tissue heterogeneity.

Low-methoxy-pectin and chlorogenic acid synergistically promote lipolysis and β-oxidation by regulating AMPK signaling pathway in obese mice.

Chlorogenic acid (CGA) displays various biological activities in preventing high-calorie diet-induced metabolic complications. The absorption efficiency of CGA in the stomach and small intestine is relatively low, with approximately 70 % of CGA being metabolized by colonic microorganisms before it enters the bloodstream. In this study, we successfully developed CGA-LMP (Low-methoxy-pectin) conjugates to improve the absorption rate of CGA.

Decoding potential targets and pharmacologic mechanisms of curcumin in treating non-small cell lung carcinoma via bioinformatics and molecular docking.

Emerging evidence demonstrates that curcumin has an inhibitory effect on non-small cell lung cancer (NSCLC), and its targets and mechanism of action need further exploration. The goal of this study was to explore the potential targets and mechanism of curcumin against NSCLC by network pharmacology, bioinformatics, and experimental validation, thereby providing more insight into combination treatment with curcumin for NSCLC in preclinical and clinical research. Curcumin targets against NSCLC were predicted based on HIT2.

Comprehensive evaluation of the distribution, transport and ecological risk of heavy metals in intra-urban river sediments using high-resolution techniques.

Determining the distribution trends, transport mechanisms, and ecological risks of heavy metals (HMs) in urban river sediments is essential for the government to conduct appropriate remediation work. In this study, we collected sediment cores from the Yayao Waterway in Foshan City, China. The vertical distribution profiles of dissolved and labile Fe, Mn, Cd, Zn, Cu, Cr, Ni, Pb, As, and Co in the sediments were obtained using the thin-film diffusive gradient (DGT) and high-resolution peeper (HR-Peeper) techniques.

Pan-cancer analysis of TMEM45A and exploration of its prognostic value and mechanism in gastric cancer.

Cancer is a major category of diseases that need to be addressed urgently, bringing a huge burden to the world. Gastric cancer (GC) is a frequent malignant tumor of the digestive system with the highest incidence and mortality rate among all tumors. The purpose of this study was to explore the mechanism of action of TMEM45A in pan-cancer and gastric cancer.

Interferon-α could induce liver steatosis to promote HBsAg loss by increasing triglyceride level.

Background: The correlation between metabolic syndrome (MetS) and hepatitis B surface antigen (HBsAg) loss remains to be further elucidated, particularly in patients receiving pegylated interferon-α (PEG-IFN) treatment.

Methods: 758 patients with low HBsAg quantification who had received nucleos(t)ide analog (NUC) therapy for at least one year and subsequently switched to or add on PEG-IFN therapy over an unfixed course were enrolled. 412 patients were obtained with baseline data matched.

Neural dysfunction underlying working memory processing at different stages of the illness course in schizophrenia: a comparative meta-analysis.

Schizophrenia, as a chronic and persistent disorder, exhibits working memory deficits across various stages of the disorder, yet the neural mechanisms underlying these deficits remain elusive with inconsistent neuroimaging findings. We aimed to compare the brain functional changes of working memory in patients at different stages: clinical high risk, first-episode psychosis, and long-term schizophrenia, using meta-analyses of functional magnetic resonance imaging studies. Following a systematic literature search, 56 whole-brain task-based functional magnetic resonance imaging studies (15 for clinical high risk, 16 for first-episode psychosis, and 25 for long-term schizophrenia) were included.

Maltose Additive Enables Compacted Deposition of Zn Ions for Stabilizing the Zn Anode.

Aqueous zinc-ion batteries (AZIBs) have emerged as one of the most promising energy storage technologies due to their high safety and cost-effectiveness. However, several challenges associated with the Zn metal anode, such as dendrite growth, corrosion, and hydrogen evolution reaction (HER), have hindered further applications of AZIBs. Herein, maltose (MT) is used as a functional electrolyte additive to protect the Zn metal electrode during the interface deposition process.

Computer-vision-based plant leaf segmentation technology is of great significance for plant classification, monitoring of plant growth, precision agriculture, and other scientific research. In this paper, the YOLOv8-seg model was used for the automated segmentation of individual leaves in images. In order to improve the segmentation performance, we further introduced a Ghost module and a Bidirectional Feature Pyramid Network (BiFPN) module into the standard Yolov8 model and proposed two modified versions.
