Lipid peroxidation is a complex biochemical process associated with oxidative stress, and its products play crucial roles in cellular signaling and the pathophysiology of many diseases. Among the diverse array of lipid peroxidation (LPO) products, epoxyketooctadecenoic acids (EKODEs) have emerged as intriguing molecules with potential impacts on inflammatory diseases. EKODEs arise from linoleic acid reacting with reactive oxygen and nitrogen species present during inflammation. A hallmark of many LPO products is an electrophilic chemical functionality that can react with different biological nucleophiles to form adducts that impact a broad swath of physiologic processes. Here, we present the identification of reactivity patterns exhibited by the EKODE class of LPO products that arise due to the unique chemistry of the EKODE electrophiles, namely α, β-unsaturated epoxyketones of variable regiochemistry. Our initial investigations with models of the EKODE reactive core showed that surrogates of lysine did not react, and histidine nucleophiles formed reversible Michael adducts. However, when models of cysteine nucleophiles were tested, a unique reactivity profile emerged where rapid Michael addition was followed by slow rearrangement and epoxide opening at an unpredicted electrophilic site, affording what we postulated to be an advanced lipoxidation end product (ALE). After confirming the EKODE reactivity in model systems, we produced polyclonal antibodies of a stable epitope of the EKODE-based ALE and used these antibodies to investigate an approach for in vivo monitoring of inflammatory disease progression.

Antibody generation requires the use of one or more time-consuming methods, namely animal immunization, and in vitro display technologies. However, the recent availability of large amounts of antibody sequence and structural data in the public domain along with the advent of generative deep learning algorithms raises the possibility of computationally generating novel antibody sequences with desirable developability attributes. Here, we describe a deep learning model for computationally generating libraries of highly human antibody variable regions whose intrinsic physicochemical properties resemble those of the variable regions of the marketed antibody-based biotherapeutics (medicine-likeness). We generated 100000 variable region sequences of antigen-agnostic human antibodies belonging to the IGHV3-IGKV1 germline pair using a training dataset of 31416 human antibodies that satisfied our computational developability criteria. The in-silico generated antibodies recapitulate intrinsic sequence, structural, and physicochemical properties of the training antibodies, and compare favorably with the experimentally measured biophysical attributes of 100 variable regions of marketed and clinical stage antibody-based biotherapeutics. A sample of 51 highly diverse in-silico generated antibodies with >90th percentile medicine-likeness and > 90% humanness was evaluated by two independent experimental laboratories. Our data show the in-silico generated sequences exhibit high expression, monomer content, and thermal stability along with low hydrophobicity, self-association, and non-specific binding when produced as full-length monoclonal antibodies. The ability to computationally generate developable human antibody libraries is a first step towards enabling in-silico discovery of antibody-based biotherapeutics. These findings are expected to accelerate in-silico discovery of antibody-based biotherapeutics and expand the druggable antigen space to include targets refractory to conventional antibody discovery methods requiring in vitro antigen production.

Cerebral ischemia/reperfusion injury (CIRI) is a major complication of acute ischemic stroke (AIS), characterized by calcium overload, oxidative stress, and cell apoptosis. In this study, we investigated the therapeutic potential of Genistein (Gen) in alleviating CIRI by focusing on its effects on the Wnt/Ca2+ signaling pathway. Using a rat model of cerebral ischemia/reperfusion and in vitro experiments on PC12 cells, we observed that Gen treatment reduced infarct size, improved neurological function, and mitigated calcium overload, oxidative stress, and apoptosis. Further analysis revealed that Gen regulates key proteins in the Wnt/Ca2+ signaling pathway, including Wnt5a and Frizzled-2, effectively preventing intracellular calcium accumulation and subsequent damage. The knockdown of Frizzled-2 confirmed the pathway's role in mediating calcium overload and subsequent damage. Our findings suggest that Gen alleviates CIRI by inhibiting the Wnt/Ca2+ signaling pathway, positioning it as a promising candidate for therapeutic intervention in stroke treatment.

Oligonucleotide-based therapy has experienced remarkable development in the past 2 decades, but its broad applications are severely hampered by delivery vectors. Widely used viral vectors and lipid nanovectors are suffering from immune clearance after repeating usage or requiring refrigerated transportation and storage, respectively. In this work, amino-modified virus-mimetic spike silica nanoparticles (NH2-SSNs) were fabricated using a 1-pot surfactant-free approach with controlled spike lengths, which were demonstrated with excellent delivery performance and biosafety in nearly all cell types and mice. It indicated that NH2-SSNs entered cells by spike-dependent cell membrane docking and dynamin-dependent endocytosis. The positively charged spikes with proper length on the surface can facilitate the efficient encapsulation of RNAs, protect the loaded RNAs from degradation, and trigger an early endosome escape during intracellular trafficking, similarly to the cellular internalization mechanism of virions. Regarding the fantastic properties of NH2-SSNs in nucleic acid delivery, it revealed that nanoparticles with solid spikes on the surface would be excellent vehicles for gene therapy, presenting self-evident advantages in storage, transportation, modification, and quality control in large-scale production compared to lipid nanovectors.

Alcohol abuse is one of the major public health problems in the world and is associated with various health conditions. However, little is known about the effect of alcohol consumption on acute kidney injury (AKI). In this study, we demonstrate that chronic and binge alcohol feeding with a Lieber-DeCarli diet containing 5 % ethanol for 10 days, followed by a single dose of 31.5 % ethanol by gavage, aggravated AKI after ischemia-reperfusion injury (IRI) in female, but not in male, mice. Kidney dysfunction, histopathology and tubular cell apoptosis were more severe in EtOH-fed female mice after IRI, compared to pair-fed controls. RNA sequencing and experimental validation uncovered that activation of integrin β1 and its downstream c-Jun NH2-terminal kinase (JNK) aggravated AKI in EtOH-fed mice. Knockdown of integrin β1 inhibited JNK phosphorylation and alleviated AKI in EtOH-fed mice, whereas activation of integrin β1 by agonist antibody increased JNK phosphorylation, worsened renal histological injury and tubular cell apoptosis, and aggravated kidney dysfunction. In vitro, activation of integrin β1 increased JNK phosphorylation and induced tubular epithelial cell apoptosis. The detrimental effect of EtOH feeding was primarily mediated by acetaldehyde, as its levels were increased in the blood, liver and kidney of female mice fed with ethanol. Acetaldehyde per se activated integrin β1/JNK signaling and induced tubular cell apoptosis in vitro. These findings suggest that alcohol consumption increases vulnerability to AKI in female mice, which is probably mediated by acetaldehyde/integrin β1/JNK signaling cascade.

The AlkB homolog 7 (ALKBH7) is a nonheme iron (II) α-ketoglutarate-dependent dioxygenase superfamily member, which may affect the progression of several types of human cancer. However, the biological effect, especially the immune-related effect, of ALKBH7 in HNSC remains unclear. Herein, several databases were employed at first to assess the different expression of ALKBH7 as well as their relationship to the prognosis, RNA modification, DNA methylation modulation, immune microenvironment and chemotherapeutic responses of various types of cancers. We found that ALKBH7 was expressed differentially in pan-cancer, and correlated with a satisfied prognosis especially in HNSC. The expression of ALKBH7 was also associated with the level of immune cell infiltration, TMB, MSI, HRD, MMR deficiency, and DNA methyltransferases in a wide variety of cancers, which might be potentially related to the responses against chemotherapeutic agents. Next, the role of ALKBH7 in HNSC was further investigated. Western blot and immunohistochemical analysis in HNSC patients from the NMU cohort showed the reduced ALKBH7 expression level in tumor tissues. In vitro experiments of cell migration, invasion, and proliferation showed a potential protective effect of ALKBH7 in HNSC. Collectively, ALKBH7 might play a protective role in the development and progression of multiple cancers by affecting the metabolism and immune cell infiltration, especially HNSC, which could be a potential biomarker to predict prognosis and chemotherapeutic response.

Chinese baijiu is highly regarded for its unique flavor, and a variety of crops can be utilized as raw materials in its production. Waxy crops are essential ingredients in the brewing of high-quality baijiu; however, there is currently no comprehensive identification of volatile organic compounds (VOCs) and non-volatile compounds (N-VOCs) in waxy wheat baijiu (WWB). This study aims to investigate the dynamic changes of VOCs and N-VOCs in WWB during several important time periods from new to aged. A total of 25 amino acids underwent changes in the samples, with numerous physiologically active beneficial amino acids showing significant accumulation after aging. Additionally, 517 VOCs changed after aging, predominantly comprising esters and terpenoids, with 72 major VOCs being identified. A total of 718 metabolites were identified in the metabolome, primarily comprising alterations in lipids, amino acids, phenolic acids, organic acids, and alkaloids. These metabolites significantly influenced the levels of amino acids and VOCs. Our study is the first to provide a comprehensive examination of these aspects of WWB, highlighting its unique advantages over other crops. We believe that this research will establish a theoretical foundation for the application of waxy wheat in the baijiu industry, improve baijiu quality, and promote the development of functional baijius.

Reynoutria ciliinervis (Nakai) Moldenke (R. ciliinervis) root, a traditional Chinese medicine, was found to exhibit remarkable pharmacological properties through a series of comprehensive investigations. Our study commenced with a qualitative phytochemical analysis that identified 12 bioactive compounds within the plant. Subsequently, utilizing ultraviolet-visible spectrophotometry, the methanol extract emerged as the optimal solvent extract, which was abundant in diverse classes of compounds such as carbohydrates, phenolics, steroids, alkaloids, phenolic acids, and tannins. In vitro antioxidant assays underscored the exceptional free radical scavenging, metal ion chelation, hydrogen peroxide scavenging, singlet oxygen quenching, and β-carotene bleaching capabilities of the methanol extract, significantly outperforming other solvent extracts. Further ultra high-performance liquid chromatography-electrospray ionization-quadrupole time of flight-mass spectrometry analysis revealed the presence of 45 compounds, predominantly anthraquinones and phenolics, in the methanol extract. The extract demonstrated robust stability under various conditions, including high temperatures, varying pH levels, and simulated gastrointestinal digestion as well as efficacy in inhibiting the oxidation in edible oils. Acute toxicity tests in mice confirmed the safety of the methanol extract and provided a valuable dosage reference for future studies. Importantly, high-dose methanol extract exhibited a significant pre-protective effect against D-galactosamine-induced liver injury in rats, as evidenced by reduced alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transpeptidase, malondialdehyde levels, and elevated catalase and albumin levels. These findings suggest a potential role for the methanol extract of R. ciliinervis root in treating oxidative stress-related disorders, highlighting the plant's immense medicinal potential. Our research offers a thorough evaluation of the bioactive components, antioxidant properties, stability, and liver-protecting effects of the methanol extract, setting the stage for deeper investigation and potential clinical applications.

Although intermittent theta burst stimulation (iTBS) has shown effectiveness in addressing working memory (WM) deficits in individuals with schizophrenia (SZ), the current body of evidence is limited and the specific mechanisms involved remain unclear. Therefore, this pilot fMRI study aimed to examine the efficacy of parietal iTBS in ameliorating WM impairments and explore its influence on the resting-state effective connectivity within the frontoparietal network in patients with SZ.

Levels of self-management behaviors (SMB) and quality of life (QoL) are suboptimal in Chinese adults with type 2 diabetes (T2D), especially in rural China. Integrated health management within a county medical consortium, featuring multi-level teams of doctors, nurses, and other professionals offering follow-up services such as check-ups, assessments, treatment, and health education, is promising in improving this. This study aimed to assess the effect of integrated health management within a county medical consortium on the SMB and QoL of rural T2D patients in China.

The possible protective effect of interleukin-32 (IL-32) in Mycobacterium tuberculosis (Mtb) infection has been indicated. However, few studies have been focused on IL-32 in tuberculosis patients. Additionally, the regulation of IL-32 production has rarely been reported. In the present study, the production, regulation, and role of IL-32 in tuberculous pleurisy (TBP) were investigated. We found that the content of IL-32 in tuberculous pleural effusion (TPE) was higher than the level in the malignant pleural effusion and transudative pleural effusion. The level of IL-32 mRNA in pleural fluid mononuclear cells (PFMCs) was higher than that in peripheral blood mononuclear cells (PBMCs) of patients with TBP, and this difference was mainly reflected in the splice variants of IL-32α, IL-32β, and IL-32γ. Compared with the PBMCs, PFMCs featured higher IL-32β/IL-32γ and IL-32α/IL-32γ ratios. In addition, lipopolysaccharide (LPS), Bacillus Calmette-Guérin (BCG), and H37Ra stimulation could induce IL-32 production in the PFMCs. IL-32 production was positively correlated with the TNF-α, IFN-γ, and IL-1Ra levels in TPE, whereas IFN-γ, but not TNF-α or IL-1Ra, could induce the production of IL-32 in PFMCs. Furthermore, IL-32γ could induce the TNF-α production in PFMCs. Monocytes and macrophages were the main sources of IL-32 in PFMCs. Nevertheless, direct cell-cell contact between lymphocytes and monocytes/macrophages plays an important role in enhancing IL-32 production by monocyte/macrophage cells. Finally, compared with the non-tuberculous pleural effusion, the purified CD4+ and CD8+ T cells in TPE expressed higher levels of intracellular IL-32. Our results suggested that, as a potential biomarker, IL-32 may play an essential role in the protection against Mtb infection in patients with TBP. However, further studies need to be carried out to clarify the functions and mechanisms of the IFN-γ/IL-32/TNF-α axis in patients with TBP.

Repairing large bone defects remains a significant clinical challenge. Stem cell is of great importance in bone regeneration, and periosteum is rich in periosteal stem cell, which has a great influence on repairing bone defects. Bioengineered periosteum with excellent biocompatibility and stem cell homing capabilities to promote bone regeneration is of great clinical significance. The E7 peptide (EPLQLKM), which exhibits a specific affinity for mesenchymal stem cells (MSCs), is beneficial for modulating cellular functions. In this study, a unique microporous structured carboxymethyl chitosan/sodium alginate membrane with a proper mass ratio is developed by the addition of Poloxam 407 （P407）, which is then functionalized with the E7 affinitive peptide. This membrane, characterized by its microporous structure and E7 peptide functionalization (CSSA/P/E), not only demonstrated favorable mechanical properties, enhanced hydrophilicity, satisfactory biodegradation profile, and excellent biocompatibility, but also synergistically enhanced MSCs recruitment. It is found to promote the proliferation, spreading, and osteogenic differentiation of MSCs in vitro and to accelerate early periosteal regeneration, bone matrix deposition, and vascularization in vivo, leading to effective regeneration of critical-sized bone defects. Overall, this study presents a robust, cell and growth factor-free strategy for bioengineering periosteum, offering a potential solution for the challenging large size bone defects.

Fibroblast growth factor 21 (FGF21) is a peptide hormone that is primarily expressed and secreted by the liver. The hormone is crucial for regulation of glucose homeostasis, lipid metabolism, and energy balance. Compared with natural FGF21, FGF21 analogs have become drug candidates for the treatment of cardiovascular and metabolic diseases owing to their long half-life and greater stability in vitro. Apolipoprotein E (Apoe)-knockout (Apoe -/-) mice exhibit progressive disruptions in lipid metabolism in vivo and develop further atherosclerosis pathological features owing to Apoe deletion. Therefore, this study used an Apoe -/- mouse model to investigate the effects of a long-acting FGF21 analog (PF-05231023) on lipid metabolism and related parameters. Eighteen Apoe -/- female mice were fed a Western diet equivalent for 12 weeks, and then randomly assigned to intraperitoneally receive either physiological saline (the control group) or 10 mg/kg PF-05231023 (the treatment group) three times a week for seven consecutive weeks. Body composition, glucose tolerance, blood and liver cholesterol, triglyceride levels, liver vacuolization levels, peri-ovarian white adipocyte hypertrophy, aortic atherosclerotic plaque formation, and the expression of genes related to lipid metabolism in adipose tissue were subsequently assessed before and after treatment. The aortic atherosclerotic plaque area was reduced in mice in the PF-05231023 treatment group compared with that in the saline group. Although the effect of PF-05231023 on the plasma biochemical indexes of mice was small, it significantly reduced lipid levels and lipid droplet accumulation in the liver, and reduced adipocyte hypertrophy in white adipose tissue. Transcriptome analysis of adipose tissue showed that PF-05231023 treatment downregulated the expression of lipid synthesis-related genes and inhibited the sterol regulatory element binding transcription factor 1 gene, thereby improving lipid deposition. PF-05231023 effectively improved the lipid metabolism of Apoe -/- mice, demonstrating an anti-atherosclerotic effect and providing a scientific basis and experimental foundation for the clinical treatment of cardiovascular diseases by using long-acting FGF21 analogs.

The study of comprehensive satisfaction with healthcare is still limited due to nonstandard measurement tools of patient satisfaction for the Chinese population. Therefore, the present study aimed to verify the validity, reliability, and measurement invariance of the revised Patient Satisfaction Questionnaire (PSQ-R) and conducted network analysis among a sample of the Chinese population.

Silica nanoparticles (SiNPs) and cadmium are major environmental pollutants that have severe detrimental effects on living organisms. Recent studies have demonstrated that the combined exposure of SiNPs and heavy metals is more toxic than individual exposure. However, studies on the effects of the combined exposure of SiNPs and cadmium, on the cardiovascular system are rare. In this study, zebrafish (Danio rerio) embryos were exposed to a combination of SiNPs and experimentally safe concentrations CdCl2 for studying the alterations in heart morphology, heart rate, apoptosis, and vascular endothelial cells. The results demonstrated that the detrimental effects of SiNPs+CdCl2 exposure on the heart rate and vascular endothelial cells were more severe than those following exposure to SiNPs or CdCl2 alone. Gene expression analysis revealed that apoptosis and inflammation could be the major pathways underlying the toxicity caused by the combined exposure of SiNPs and CdCl2.

Lycopene, a natural carotenoid, has potential chemopreventive effects in many cancers. This study aimed to examine the effects of lycopene on regulating the inflammation and apoptosis of N-nitrosomethylbenzylamine(NMBzA) induced esophageal cancer in F344 rats. After the rats were fed normal diets containing different concentrations of lycopene for 25 weeks (10, 25, 50 mg/kg·d of lycopene, respectively), the incidence of tumors in the rats treated with lycopene was significantly lower than that in the simple exposed group (P < 0.05). The antioxidant activity of lycopene was exerted by measuring the levels of GSH-PX, SOD and MDA activity by oxidative stress kits. Furthermore, through western blotting analysis lycopene intervention was found to have significantly improved apoptosis cytokines by increasing the protein expression levels of PPARγ and caspase-3, and also significantly reduced inflammatory cytokines by decreasing the protein expression of NF-κB and COX-2 in the esophagus tissue, especially in the 25 mg/kg of lycopene intervention group (all P < 0.05). These results demonstrated that appropriate dose of lycopene intervention could inhibit the carcinogenesis of esophageal in F344 rats through the possible mechanisms of anti-inflammatory and pro-apoptosis.

Recently, accumulating data have supported that long non-coding RNAs (lncRNAs) may contribute to tumorigenesis. LncRNA LINC00511 (LINC00511) has been proved to serve as an oncogene in several tumors. However, as a novel lncRNA, the crucial role and potential mechanism of LINC00511 in LUSC is largely unknown.
