Analysis of thyroid function and structure and serum metabolomics in pregnant rats exposed to airborne contaminants: Combined perchlorate, thiocyanate, and nitrate exposure.

Objectives: Perchlorates, nitrates, and thiocyanates constitute environmental endocrine disruptors; however, health damage caused by absorption through the respiratory tract remains poorly studied. We investigated the effects of inhalation of these pollutants on thyroid function and structure and serum metabolomics in pregnant rats.

Methods: We established a Sprague-Dawley pregnant rat model exposed to perchlorate, nitrate, and thiocyanate at different gestational stages and compared maternal serum thyroid function levels, foetal development, thyroid morphology, and pathological changes between exposed and non-exposed groups at different concentrations.

Melittin inhibits MPP-induced HT22 cell death by suppressing Bax activation and improving mitochondrial function.

Melittin (MEL) is the main bioactive component of bee venom and has been reported to have various pharmacological effects. This study investigates the protective effect of MEL on MPP-injured HT22 cells and the possible mechanisms involved. We treated the cells with 4 mM MPP for 24 h to induce a cellular injury model.

OsPIL15-Induced Delay in Rice Heading Date via Direct Binding to the OsLF Promoter is Dependent on Functional Phytochrome B.

Heading date of rice (Oryza sativa) is a key factor determining rice production and regional adaptability. We analysed the molecular mechanism of OsPIL15, encoding phytochrome-interacting factor-like protein, in delaying rice heading date. Overexpression of OsPIL15 delayed rice heading date by upregulating Hd1 and inhibiting Hd3a and RFT1 expression.

Daphnetin may protect from SARS-CoV-2 infection by reducing ACE2.

To combat the SARS-CoV-2 pandemic, innovative prevention strategies are needed, including reducing ACE2 expression on respiratory cells.

Upgrading the Bioinspired Iron-Polyporphyrin Structures by Abiological Metals Toward New-Generation Reactive Oxygen Biocatalysts.

Developing artificial enzymes based on organic molecules or polymers for reactive oxygen biocatalysis has broad applicability. Here, inspired by heme-based enzyme systems, we construct the abiological iron group metal-based polyporphyrin (Ru/Os-coordinated porphyrin-based biocatalyst, Ru/Os-PorBC) to serve as a new generation of efficient and versatile reactive oxygen species (ROS)-related biocatalyst. Due to the structural benefits, including excellent electron configuration, appropriate bandgap, and optimized adsorption and activation of reaction intermediates, Ru/Os-PorBC shows unparalleled ROS-production activities regarding maximum reaction rate and turnover numbers, which also demonstrates superior pH and temperature adaptability compared to natural enzymes.

We aimed to examine the trend of lung cancer incidence and mortality from 2012 to 2023, and predict the lung cancer burden to 2030 in Shandong.

Esketamine and neurocognitive disorders in adult surgical patients: a meta-analysis.

Background: Prior meta-analyses have established the potential of intravenous ketamine in safeguarding against neurocognitive impairment, but the efficacy of intravenous esketamine for the prevention of perioperative neurocognitive disorders (PND) remains uncertain. The primary aim of this meta-analysis was to conduct a comprehensive evaluation of the effects of esketamine on PND in adult surgical patients undergoing general anesthesia.

Methods: We searched several electronic databases and clinical trial registries to find relevant trials.

Transcriptome-wide methylated RNA immunoprecipitation sequencing profiling reveals m6A modification involved in response to heat stress in Apostichopus japonicus.

Background: Global warming-induced environmental stresses have diverse effects on gene expression and regulation in the life processes of various aquatic organisms. N6 adenylate methylation (m6A) modifications are known to influence mRNA transcription, localization, translation, stability, splicing, and nuclear export, which are pivotal in mediating stress responses. Apostichopus japonicus is a significant species in aquaculture and a representative of benthic organisms in ecosystems, thus there is a growing need for research on its heat stress mechanism.

Redox nanodrugs alleviate chronic kidney disease by reducing inflammation and regulating ROS.

Immune-mediated glomerular diseases lead to chronic kidney disease (CKD), primarily through mechanisms such as immune cell overactivation, mitochondrial dysfunction and imbalance of reactive oxygen species (ROS). We have developed an ultra-small nanodrug composed of MnO nanoparticles which is functionalized with biocompatible ligand citrate (C-MnO NPs) to maintain cellular redox balance in an animal model of oxidative injury. Furthermore, this ultra-small nanodrug, loaded with tacrolimus (Tac), regulated the activity of immune cells.

Puerarin reduces diabetic nephropathy-induced podocyte pyroptosis by modulating the SIRT1/NLRP3/caspase-1 pathway.

Background: Chronic kidney inflammation and podocyte injury are key pathological features of Diabetic Nephropathy (DN). Puerarin has been shown to inhibit podocyte pyroptosis and provide renal protection, although its molecular mechanism remains unclear.

Methods: The effects and mechanisms of puerarin on podocyte pyroptosis were investigated in a DN mouse model.

Development of a Method for the Determination of Rifaximin and Rifampicin Residues in Foods of Animal Origin.

Rifaximin and rifampicin are good broad-spectrum antimicrobials. The irrational use of antimicrobial drugs in veterinary clinics could threaten public health and food safety. It is necessary to develop a reliable detection method of the residue for enhancing the rational supervision of the use of such drugs, reducing and slowing down the generation of bacterial resistance, and promoting animal food safety and human health.

NADPH Oxidases-Inspired Reactive Oxygen Biocatalysts with Electron-Rich Pt Sites to Potently Amplify Immune Checkpoint Blockade Therapy.

Clinical immune checkpoint blockade (ICB)-based immunotherapy of malignant tumors only elicits durable responses in a minority of patients, primarily due to the highly immunosuppressive tumor microenvironment. Although inducing immunogenic cell death (ICD) through reactive oxygen biocatalyst represents an attractive therapeutic strategy to amplify ICB, currently reported biocatalysts encounter insurmountable challenges in achieving high ROS-generating activity to induce potent ICD. Here, inspired by the natural catalytic characteristics of NADPH oxidases, the design of efficient, robust, and electron-rich Pt-based redox centers on the non-stoichiometric WO substrates (Pt─WO) to serve as bioinspired reactive oxygen biocatalysts to potently activate the ICD, which eventually enhance cancer immune responses and amplifies the ICB-based immunotherapy is reported.

Silencing AREG Enhances Sensitivity to Irradiation by Suppressing the PI3K/AKT Signaling Pathway in Colorectal Cancer Cells.

Background: It has been established that Spalt-Like Transcription Factor 4 (SALL4) promotes Colorectal Cancer (CRC) cell proliferation. Furthermore, Amphiregulin (AREG) is crucially involved in cancer cell proliferation and therapeutic resistance regulation. In this regard, this study aimed to establish whether SALL4 affects the radiosensitization of CRC cells via AREG expression regulation.

Shenqi Sanjie Granules induce Hmox1-mediated ferroptosis to inhibit colorectal cancer.

Background: Because adverse reactions or drug resistance are often found after current chemotherapies for metastatic colorectal cancer (mCRC), new treatments are still in demand. Shenqi Sanjie Granules (SSG), an antitumor compound preparation of traditional Chinese medicine, has been recognized for its ability in clinical practice of oncotherapy. Nevertheless, the precise effects of SSG in colorectal cancer (CRC) and underlying mechanisms through which SSG inhibits CRC remain uncertain.

Does better regulatory institutions always enhance the productivity effects of services trade liberalization？.

The majority of previous studies have asserted that the high quality of local institutions can improve the productivity effects of trade policies; yet, only a few studies have acknowledged the heterogeneous impact of these institutions. Using data from Chinese manufacturing plants, we examine the moderating effects of regional-level regulations on the effectiveness of national services trade policy. The key findings are threefold: First, as the initial degree of service liberalization advances, the productivity effect of trade liberalization diminishes.
