Background: High blood pressure (BP) is a known risk factor for cognitive decline and dementia, but the underlying mechanisms are largely unknown. We investigated the associations of cumulative BP exposure with hippocampal subfield volume and cognitive function and determined whether hippocampal subfield atrophy mediates the association between cumulative BP exposure and cognitive decline.

Methods: Between December 2020 and March 2023, participants were prospectively included from the Kailuan study.

N-terminal glycine (Gly/N-degron), as a degradation signal, can be recognized by specific E3 ubiquitin ligases and plays a crucial role in protein degradation and cellular homeostasis. As a substrate receptor in the Cullin 2-RING E3 ligase complex, ZER1 mediates protein degradation the Gly/N-degron pathway by recognizing N-terminal glycine and other small residues. This study employed all-atom molecular dynamics (MD) simulations and binding free energy calculations to explore ZER1's recognition of the wild-type peptide GFLHVGQD (WT) and its N-terminal mutants (G1S, G1A, G1T, and G1C).

Polycystic Ovary Syndrome (PCOS) is a prevalent endocrine and metabolic condition among women of reproductive age, frequently associated with oxidative stress (OS) and chronic low-grade inflammation. Low-Intensity pulsed ultrasound (LIPUS) is a safe, non-invasive physical therapy method widely used in promoting fracture healing, soft tissue repair, and reducing inflammation. This study explored the improving effect of LIPUS on ovarian function in PCOS rat models induced by letrozole and a high-fat diet.

Electroencephalography (EEG) usage in emotion recognition has garnered significant interest in brain-computer interface (BCI) research. Nevertheless, in order to develop an effective model for emotion identification, features need to be extracted from EEG data in terms of multi-view. In order to tackle the problems of multi-feature interaction and domain adaptation, we suggest an innovative network, IF-MMCL, which leverages multi-modal data in multi-view representation and integrates an individual focused network.

Research Question: Can the use of pyrroloquinoline quinone (PQQ) to treat premature ovarian insufficiency (POI) induced by cyclophosphamide (CTX) in rats restore ovarian function?

Design: Thirty female Sprague-Dawley rats were divided at random into three groups: control group (n = 10), POI group (n = 10), and POI-PQQ group (n = 10). An ovarian aging model was induced by CTX and treated with PQQ. The body weight of the rats was monitored throughout the process, and serum samples were collected to determine hormone concentrations.

Objective: The aim of this study is to evaluate the influence of altered expression of indoleamine 2,3-dioxygenase 1 (IDO1) on key enzymes and metabolites within the tryptophan-kynurenine pathway, as well as to assess the resulting effects on the malignant biological behavior of cervical cancer cells, including proliferation, invasion and migration.

Methods: IDO1 expression was assessed in cervical cancer and normal cervical tissues via immunohistochemistry and western blot (WB) analysis. Four human cervical cancer cell lines (HeLa, C33A, SiHa, CaSki) were cultured, and HeLa and SiHa cells-characterized by elevated IDO1 expression-were selected for further experimentation.

To address limitations in previous domestic and international studies on "the effect of background interference on volleyball learning", the present study selected 60 students majoring in physical education from the 2021 class at Qufu Normal University as experimental subjects to examine their skill acquisition. This study aimed to explore the differential effect of background interference on the learning of volleyball serving technique of students majoring in physical education. During an 8-week teaching experiment, the effects of three training modes, namely group block practice (low interference), mixed practice (medium interference), and random practice (high interference), on the learning effect of the serving technique of 60 physical education majors were compared.

Ultraviolet A light-emitting diode (UVA-LED) is an emerging non-chemical technology with potential of enhancing postharvest quality of fresh produce. This study compared effects of UVA-LED irradiation (0-control, 4, 8, 12, 16, 20 J/cm) on senescence and shelf-life of minimally processed pakchoi (MPP). An 8 J/cm dose effectively preserved chlorophyll and color, extending 2 days shelf-life.

Background: The polarization status and function of tumor-associated macrophages (TAMs) influence tumor progression and patients' prognosis. CCAAT/enhancer-binding proteins (CEBPs) family are important transcriptional factors in macrophages differentiation physically and pathologically. This study aims to explore the mechanism of CEBPs in TAMs polarization in clear cell renal cell carcinoma (ccRCC) immune microenvironment and its impact on immune checkpoint blockers (ICBs) therapy.

Cannabidiol (CBD) exhibits various pharmacological properties, including antidepressant, antioxidant, antipsychotic, analgesic, and neuroprotective effects. However, the low natural yields of CBD and the restricted biosynthetic pathways currently limit its commercial viability and demand in the marketplace. This study evaluated the potential of 101 endophytic fungi from for biotransformation and CBD synthesis.

Pipelines in soft soil are prone to deformation and failure under traffic loads. Therefore, it is highly important to accurately characterize the dynamic response of pipelines under traffic loads and reasonably evaluate their operational status. First, for rigid pipelines, a Dload subroutine is written in the FORTRAN language to accurately characterize traffic loads, and a 3D numerical analysis model of the rigid pipe‒soil system is established using ABAQUS software to simulate the dynamic response of rigid pipelines in soft soil under traffic loads.

Waste plastics represent a new resource for the chemical industry. In this study, we demonstrate a solvent-switching strategy to upcycle waste polyethylene terephthalate (PET) into monomer terephthalic acid (TPA) and key bulk feedstocks for biodegradable polymers, such as lactic acid (LA) or glycolic acid (GA). PET undergoes rapid and mild depolymerization into its monomers TPA and ethylene glycol (EG) under the catalysis of a manganese complex.
