Intestinal metaplasia key molecules and UPP1 activation via Helicobacter pylori /NF-kB: drivers of malignant progression in gastric cancer.

Gastric cancer (GC) remains a significant global health challenge due to its high morbidity and mortality rates. The development of GC is a multi-hit process and the exploration of precancerous lesions is crucial. To elucidate the molecular and cellular dynamics underlying gastric carcinogenesis, we conducted an integrative single-cell RNA sequencing analysis of 26,028 high-quality cells from gastric antral mucosa biopsies across various stages, including non-atrophic gastritis, chronic atrophic gastritis, intestinal metaplasia, and early gastric cancer.

Fluorometric detection and analog discrimination of melatonin by amide naphthotube-based indicator displacement assays.

Melatonin, a hormone synthesized by the pineal gland, is renowned for its pivotal role in governing circadian rhythms and its promising therapeutic attributes encompassing anti-inflammatory, anti-aging, and cancer-preventative properties. Nevertheless, the improper utilization of melatonin may lead to health hazards, highlighting the critical necessity for accurate detection of melatonin in pharmaceutical or biological samples. Furthermore, melatonin metabolites exhibit analogous chemical structures yet divergent pathophysiological functions, emphasizing the significance of distinguishing between these analogs.

Microglial DBP Signaling Mediates Behavioral Abnormality Induced by Chronic Periodontitis in Mice.

Several lines of evidence implicate that chronic periodontitis (CP) increases the risk of mental illnesses, such as anxiety and depression, yet, the associated molecular mechanism for this remains poorly defined. Here, it is reported that mice subjected to CP exhibited depression-like behaviors and hippocampal memory deficits, accompanied by synapse loss and neurogenesis impairment in the hippocampus. RNA microarray analysis disclosed that albumin D-site-binding protein (DBP) is identified as the most prominently upregulated target gene following CP, and in vivo and in vitro immunofluorescence methods showed that DBP is preferentially expressed in microglia but not neurons or astrocytes in the hippocampus.

Polyacid-Modulated Carrier Dynamic Behavior at the Interface of 0D/2D Heterojunctions.

Heterojunctions formed by polyoxometalates and 2D materials draw attention owing to their remarkable photoelectric and catalytic properties. However, the intrinsic mechanisms of polyoxometalates regulating the heterojunction photoelectric properties are unclear. Herein, we constructed two types of heterojunctions by integrating polyoxometalates (Keggin-type HPWO and Lindqvist-type HWO) on g-CN monolayers, exploring photoexcited carrier dynamics in these heterojunctions by ab initio calculations combined with nonadiabatic molecular dynamics (NAMD) simulations.

Improvement on gel properties of chicken myofibrillar protein with electron beam irradiation: Based on protein structure, gel quality, water state.

This study aimed to investigate the effects of electron beam (E-beam) irradiation at different doses (0-15 kGy) on the solubility, rheological properties, emulsification characteristics, and moisture distribution of chicken myofibrillar proteins (MPs). Irradiation treatment notably increased the solubility, surface hydrophobicity, emulsification properties, and apparent viscosity of MPs, based on conformational changes caused by irradiation-induced oxidative denaturation of proteins. However, high doses of irradiation (15 kGy) induced in excessive cross-linking and aggregation of proteins, reducing the solubility, emulsification properties, and shear stress.

Glycosylated gelatin prepared based on electron beam irradiation and its physicochemical properties.

The influence of electron beam irradiation (EBI) treatment on the modification of gelatin-galactose glycosylation was thoroughly examined. The results of the degree of grafting and browning revealed that EBI triggered the glycosylation reaction of gelatin. The degree of glycosylation exhibited a gradual increase with the rising irradiation dose, reaching a maximum of 25 kGy.

Cost-effectiveness of atezolizumab plus bevacizumab as first-line therapy for metastatic renal cell carcinoma.

Objectives: Recently, the IMmotion151 trial evaluated the safety and efficacy of atezolizumab plus bevacizumab in metastatic renal cell carcinoma (mRCC) and found that this combination led to longer progression-free survival. However, no studies have evaluated the cost-effectiveness of atezolizumab plus bevacizumab.

Methods: We constructed a Markov model to evaluate the cost-effectiveness of atezolizumab plus bevacizumab, using costs and utilities from the published studies.

Three New Species and a New Record of the Lichen Genus (Peltulaceae) from Helan Mountain in China.

In this study, a systematic taxonomic analysis was carried out on the lichen genus , collected from Helan Mountain in China; three new species (, , and ) and a new record ( (Nyl.) Egea) for China were identified. Four species were identified by morph-anatomical, chemical, and phylogenetic analyses by combining two gene loci (ITS and LSU).

Pro-apoptotic gene BAX is a pan-cancer predictive biomarker for prognosis and immunotherapy efficacy.

Background: Apoptosis Regulator BCL2 Associated X (BAX) is a pro-apoptotic gene. Apoptosis is one of the important components of immune response and immune regulation. However, there is no systematic pan-cancer analysis of BAX.

Effect of electroacupuncture of "Zusanli" (ST36) combined with capeOX on apoptosis and ferroptosis in nude mice with colorectal cancer.

Objectives: To investigate the impact of combined treatment of colorectal cancer (CRC) with electroacupuncture (EA) and capeOX (combined administration of fluorouracil, oxaliplatin and capecitabine) on the tumor volume, weight, spleen coefficient, apoptosis and ferroptosis of tumor tissue, and liver and kidney functions in nude mice with CRC, so as to explore its mechanisms underlying inhibiting CRC and alleviating toxic reactions of capeOX.

Methods: Female Balb/c nude mice were randomly assigned to 3 groups：model, capeOX, and EA+capeOX, with 8 nude mice in each group. The CRC model was established by subcutaneous injection of colon cancer cells at the right inguinal region.

Automated detection of steps in videos of strabismus surgery using deep learning.

Background: Learning to perform strabismus surgery is an essential aspect of ophthalmologists' surgical training. Automated classification strategy for surgical steps can improve the effectiveness of training curricula and the efficient evaluation of residents' performance. To this end, we aimed to develop and validate a deep learning (DL) model for automated detecting strabismus surgery steps in the videos.

Macrophage scavenger receptor-A1 promotes skeletal muscle regeneration after hindlimb ischemia.

Macrophages mediated inflammatory response is crucial for the recovery of skeletal muscle following ischemia. Thus, it's necessary to exploit macrophages based therapeutic targets for ischemic disease. Here, we found mRNA level of SR-A1 was elevated in patients with critical limb ischemia by analysis of gene expression omnibus (GEO) database.

Magnetic field-assisted adsorption of phosphate on biochar loading amorphous Zr-Ce (carbonate) oxide composite.

For metal-based phosphate adsorbents, the dispersity and utilization of surface metal active sites are crucial factors in their adsorption performance and synthesis cost. In this study, a biochar material modified with amorphous Zr-Ce (carbonate) oxides (BZCCO-13) was synthesized for the phosphate uptake, and the adsorption process was enhanced by magnetic field. The beside-magnetic field was shown to have a better influence than under-magnetic field on adsorption, with maximum adsorption capacities (123.

High Performance As-Cast Organic Solar Cells Enabled by a Refined Double-Fibril Network Morphology and Improved Dielectric Constant of Active Layer.

High performance organic solar cells (OSCs) are usually realized by using post-treatment and/or additive, which can induce the formation of metastable morphology, leading to unfavorable device stability. In terms of the industrial production, the development of high efficiency as-cast OSCs is crucially important, but it remains a great challenge to obtain appropriate active layer morphology and high power conversion efficiency (PCE). Here, efficient as-cast OSCs are constructed via introducing a new polymer acceptor PY-TPT with a high dielectric constant into the D18:L8-BO blend to form a double-fibril network morphology.
