Astragalus polysaccharide/carboxymethyl chitosan/sodium alginate based electroconductive hydrogels for diabetic wound healing and muscle function assessment.

Natural polysaccharides with excellent biocompatibility are considered ideal materials for repairing diabetic foot ulcer. However, diabetic foot ulcer is often accompanied by decreased muscle function, even resulting in muscle atrophy. During wound repair, monitoring muscle function at the wound site in real time can identify the decreased muscle strength timely, which is crucial for precise wound rehabilitation.

Insights into the tolerant function of VWA proteins in terms of expression analysis and RGLG5-VWA crystal structure.

The VWA domain commonly functions as a crucial component of multiprotein complexes, facilitating protein-protein interactions. However, limited studies have focused on the systemic study of VWA proteins in plants. Here, we identified 28 VWA protein genes in Arabidopsis thaliana, categorized into three clades, with one tandem duplication event and four paralogous genes within collinearity blocks.

Renewable Electroconductive Hydrogels for Accelerated Diabetic Wound Healing and Motion Monitoring.

Diabetic foot ulcers (DFUs), a prevalent complication of diabetes mellitus, may result in an amputation. Natural and renewable hydrogels are desirable materials for DFU dressings due to their outstanding biosafety and degradability. However, most hydrogels are usually only used for wound repair and cannot be employed to monitor motion because of their inherent poor mechanical properties and electrical conductivity.

Advancements in Stimulus-Responsive Co-Delivery Nanocarriers for Enhanced Cancer Immunotherapy.

Cancer immunotherapy has emerged as a novel therapeutic approach against tumors, with immune checkpoint inhibitors (ICIs) making significant clinical practice. The traditional ICIs, PD-1 and PD-L1, augment the cytotoxic function of T cells through the inhibition of tumor immune evasion pathways, ultimately leading to the initiation of an antitumor immune response. However, the clinical implementation of ICIs encounters obstacles stemming from the existence of an immunosuppressive tumor microenvironment and inadequate infiltration of CD8T cells.

Revisiting the Ultraviolet Absorption Cross Section of Gaseous Nitrous Acid (HONO): New Insights for Atmospheric HONO Budget.

Nitrous acid (HONO) is an important source of hydroxyl radicals (OH) in the atmosphere. Precise determination of the absolute ultraviolet (UV) absorption cross section of gaseous HONO lays the basis for the accurate measurement of its concentration by optical methods and the estimation of HONO loss rate through photolysis. In this study, we performed a series of laboratory and field intercomparison experiments for HONO measurement between striping coil-liquid waveguide capillary cell (SC-LWCC) photometry and incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS).

Danshensu methyl ester attenuated LPS-induced acute lung injury by inhibiting TLR4/NF-κB pathway.

Acute Lung Injury (ALI) manifests as an acute exacerbation of pulmonary inflammation with high mortality. The potential application of Danshensu methyl ester (DME, synthesized in our lab) in ameliorating ALI has not been elucidated. Our results demonstrated that DME led to a remarkable reduction in lung injury.

Calcium Carbonate/Polydopamine Composite Nanoplatform Based on TGF-β Blockade for Comfortable Cancer Immunotherapy.

Cancer pain seriously reduces the quality of life of cancer patients. However, most research about cancer focuses solely on inhibiting tumor growth, neglecting the issue of cancer pain. Therefore, the development of therapeutic agents with both tumor suppression and cancer pain relief is crucial to achieve human-centered treatment.

Dimethyl Bisphenolate Ameliorates Carbon Tetrachloride-Induced Liver Injury by Regulating Oxidative Stress-Related Genes.

Liver disease accounts for millions of deaths per year all over the world due to complications from cirrhosis and liver injury. In this study, a novel compound, dimethyl bisphenolate (DMB), was synthesized to investigate its role in ameliorating carbon tetrachloride (CCl)-induced liver injury through the regulation of oxidative stress-related genes. The structure of DMB was confirmed based on its hydrogen spectrum and mass spectrometry.

Characteristics and sources of peroxyacetyl nitrate (PAN) in the rural North China Plain: Results from 1-year continuous observations.

Peroxyacetyl nitrate (PAN) is an important photochemical pollutant in the troposphere, whereas long-term measurements are scarce in rural areas in North China Plain (NCP), resulting in unclear seasonal variations and sources of PAN in rural NCP. In this study, we conducted a 1-year observation of PAN during 2021-2022 at the rural NCP site. The average concentrations of PAN were 1.

Multifunctional Oxygen-Generating Nanoflowers for Enhanced Tumor Therapy.

Sonodynamic therapy (SDT) and chemotherapy have received great attention as effective methods for tumor treatment. However, the inherent hypoxia of the tumor greatly hinders its therapeutic efficacy. In this work, a tumor microenvironment-responsive biodegradable nanoplatform SiO-MnO-PEG-Ce6&DOX (designated as SMPC&D) is fabricated by encapsulating manganese oxide (MnO) into silica nanoparticles and anchoring poly(ethylene glycol) (PEG) onto the surface for tumor hypoxia relief and delivery, then loaded with sonosensitizer Chlorin e6 (Ce6) and chemotherapeutic drug doxorubicin (DOX) for hypoxic tumor treatment.

[Corrigendum] Knockdown of HOXA10 reverses the multidrug resistance of human chronic mylogenous leukemia K562/ADM cells by downregulating P‑gp and MRP‑1.

Following the publication of the above article, an interested reader drew to the authors' attention that, in Fig. 2 on p. 1408, the microscopic images shown for the light scope images (upper row) and the green fluorescence images (lower row) appeared to be overlapping, such that these images appeared to have been derived from the same original sources even though they were intended to portray the results from differently performed experiments.

Progress of research on PD-1/PD-L1 in leukemia.

Leukemia cells prevent immune system from clearing tumor cells by inducing the immunosuppression of the bone marrow (BM) microenvironment. In recent years, further understanding of the BM microenvironment and immune landscape of leukemia has resulted in the introduction of several immunotherapies, including checkpoint inhibitors, T-cell engager, antibody drug conjugates, and cellular therapies in clinical trials. Among them, the programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) axis is a significant checkpoint for controlling immune responses, the PD-1 receptor on tumor-infiltrating T cells is bound by PD-L1 on leukemia cells.

The regulation of RGLG2-VWA by Ca ions.

RGLG2, an E3 ubiquitin ligase in Arabidopsis thaliana, affects hormone signaling and participates in drought regulation. Here, we determined two crystal structures of RGLG2 VWA domain, representing two conformations, open and closed, respectively. The two structures reveal that Ca ions are allosteric regulators of RGLG2-VWA, which adopts open state when NCBS1(Novel Calcium ions Binding Site 1) binds Ca ions and switches to closed state after Ca ions are removed.
