A kidney protection nanoparticle based on Alpinia oxyphylla fructus polysaccharide by modulating macrophage polarization.

The use of natural polysaccharides from traditional Chinese medicine as carrier materials has great potentiality in drug delivery. Nootkatone (NKT) demonstrated good pharmacological activity in treating kidney injury, but its solubility and bioavailability are not very good which may affect the effectiveness of its therapeutic effect. Alpinia oxyphylla fructus polysaccharide (AOP), as a plant polysaccharide, has multiple pharmacological activities and may help to provide synergy for NKT.

Melatonin promotes the proliferation and differentiation of antler chondrocytes via RUNX2 dependent on the interaction between NOTCH1 and SHH signaling pathways.

Melatonin (MT), an endogenous hormone secreted by pineal gland, has the sedative, anti-inflammatory and antioxidant functions. However, there are few studies on whether MT affects the proliferation and differentiation of antler chondrocytes. The present study investigated the influences of MT on the proliferation and differentiation of antler chondrocytes, explored its regulation on runt-related transcription factor 2 (RUNX2), NOTCH1 and sonic hedgehog (SHH) signaling, and elucidated their interplays.

Interleukin-22 promotes endometrial carcinoma cell proliferation and cycle progression via ERK1/2 and p38 activation.

Endometrial carcinoma (EC) is one of the most common gynecological malignant tumors, but its underlying pathogenic mechanisms are largely obscure. Interleukin-22 (IL-22), one cytokine in the tumor immune microenvironment, was reported to be associated with carcinoma progression. Here, we aimed to investigate the regulation of IL-22 in endometrial carcinoma.

The development of hydroelectric projects has adversely affected the reproductive activities of downstream fish species. To facilitate the natural reproduction of fish and restore spawning grounds post-dam construction, it is imperative to explore the ecological factors crucial for their reproduction. Currently, various research methods with different advantages and limitations are employed for this purpose.

CD248-expressing cancer-associated fibroblasts induce non-small cell lung cancer metastasis via Hippo pathway-mediated extracellular matrix stiffness.

Metastasis is a crucial stage in tumour progression, and cancer-associated fibroblasts (CAFs) support metastasis through their participation in extracellular matrix (ECM) stiffness. CD248 is a possible biomarker for non-small cell lung cancer (NSCLC)-derived CAFs, but its role in mediating ECM stiffness to promote NSCLC metastasis is unknown. We investigated the significance of CD248 CAFs in activating the Hippo axis and promoting connective tissue growth factor (CTGF) expression, which affects the stromal collagen I environment and improves ECM stiffness, thereby facilitating NSCLC metastasis.

Carrier-Free Photodynamic Bioregulators Inhibiting Lactic Acid Efflux Combined with Immune Checkpoint Blockade for Triple-Negative Breast Cancer Immunotherapy.

Abnormal tumor metabolism creates a complex tumor immune microenvironment that plays a dominant role in the metastasis of triple-negative breast cancer (TNBC). TNBC is insensitive to immune checkpoint blockade (ICB) therapy because of insufficient cytotoxic T lymphocyte (CTL) infiltration and a hyper-lactic acid-suppressive immune microenvironment caused by abnormal glycolysis. Herein, we propose an amplified strategy based on lactic acid regulation to reprogram the immunosuppressive tumor microenvironment (ITM) and combine it with ICB therapy to achieve enhanced antitumor immunotherapy effects.

Quantitative determination of flow rate variations in reservoir Eco-scheduling: A case study of Yangqu dam in the upper yellow river.

Accurate quantification of flow dynamics during reservoir ecological scheduling hinders the maintenance of normal reproductive activities in downstream riverine fish. This study proposed a quantitative method for determining the flow rate changes in reservoir ecological scheduling. The approach utilized the daily flow rate and daily flow-rate increment to characterize the flow process.

Associations between a normal-range free thyroxine concentration and ovarian reserve in infertile women undergoing treatment via assisted reproductive technology.

Background: Some recent studies have shown that female subclinical hypothyroidism (SCH) is associated with diminished ovarian reserve (DOR). In this study, we aimed to investigate whether serum-free thyroxine (fT4) concentrations within the reference range are associated with ovarian reserve in women.

Methods: This cross-sectional study included 4933 infertile women with normal-range fT4 concentrations who received assisted reproductive technology treatment in our clinic.

IL-8 from CD248-expressing cancer-associated fibroblasts generates cisplatin resistance in non-small cell lung cancer.

Chemotherapy-resistant non-small cell lung cancer (NSCLC) presents a substantial barrier to effective care. It is still unclear how cancer-associated fibroblasts (CAFs) contribute to NSCLC resistance to chemotherapy. Here, we found that CD248 CAFs released IL-8 in NSCLC, which, in turn, enhanced the cisplatin (CDDP) IC50 in A549 and NCI-H460 while decreasing the apoptotic percentage of A549 and NCI-H460 in vitro.

Brain-derived extracellular vesicles mediate systemic coagulopathy and inflammation after traumatic brain injury.

Traumatic brain injury (TBI) can induce systemic coagulopathy and inflammation, thereby increasing the risk of mortality and disability. However, the mechanism causing systemic coagulopathy and inflammation following TBI remains unclear. In prior research, we discovered that brain-derived extracellular vesicles (BDEVs), originating from the injured brain, can activate the coagulation cascade and inflammatory cells.
