Ethnopharmacological Relevance: Multiple myeloma (MM) is a common hematologic malignancy. Huachansu (HCS) is extracted from the skin of Bufo bufo gargarizans, known for its well-established and multi-target anti-tumor effect. It has been reported to be effective in treating patients with multiple myeloma but its underlying mechanism remains unclear.

Although new biologicals like rituximab are changing the landscape, traditional immunosuppressants still prevail in many underdeveloped areas. One such medication is methotrexate (MTX), which has been widely used in autoimmune and autoinflammatory diseases, but its role in treating pemphigus remains somewhat unclear and controversial.

Through regulating the water activity and Zn crystal dynamics could effectively relieve those anode/electrolyte interface problems. The (2-hydroxypropyl)-β-cyclodextrin (HBCD), characterized by the excluded-volume and mitigating zinc-flux aggregation effect, is chosen as the electrolyte additive to tail the anode/electrolyte interface.
View Article and Find Full Text PDFLandfilled metallurgical residues are valuable raw materials for the recovery of strategic vanadium resources. However, efficient separation of vanadium from these residues is challenging due to its strong oxidation resistance and coating within silicate inclusions. To address this issue, this study proposes an enhanced leaching process utilizing the synergistic effect of O-catalyzed ultrasonic field in a low concentration sulfuric acid system.

Here we report the discovery of an antagonistic property of a type IV secretion system (T4SS) sourced from a conjugative plasmid, RP4, using engineering approaches. We scrutinized the genetic determinants and suggested that this antagonistic activity is independent of molecular cargos, while we also elucidated the resistance genes.

Anaerobes dominate the microbiota of the gastrointestinal (GI) tract, where a significant portion of small molecules can be degraded or modified. However, the enormous metabolic capacity of gut anaerobes remains largely elusive in contrast to aerobic bacteria, mainly due to the requirement of sophisticated laboratory settings. In this study, we employed an in silico machine learning platform, MoleculeX, to predict the metabolic capacity of a gut anaerobe, Clostridium sporogenes, against small molecules.

Therefore, based on the IRSM method in mesoscale, a novel model for predicting the elastic modulus of recycled concrete is proposed which has the advantages of being low-cost and high-precision, amongst others, compared to theoretical and experimental methods. Then, the influence of coarse aggregate, contact surface, gelling material, and air bubbles on the elastic modulus of recycled concrete is studied.

Despite the presence of a conserved catalytic tetrad and high structural similarity, these enzymes exhibit different substrate specificities. The insufficient knowledge regarding the amino acids underlying substrate specificity hinders the understanding of the SDRs' roles in diverse and significant biological processes.

Immunoglobulin A vasculitis (IgAV), also known as Henoch-Schönlein purpura, has complex etiology and pathogenesis which have not been fully clarified. The latest research shows that SARS-CoV-2 and related vaccines, human papilloma vaccine, and certain biological agents can also induce IgAV. Most studies believe that the formation of galactose-deficient IgA1 (Gd-IgA1) and Gd-IgA1-containing immune complex plays a crucial role in the pathogenesis of IgAV.

Microbial degradation of PE has been reported, but the underlying mechanisms are poorly understood. Here, we isolated a strain A34 from 609 day enriched cultures derived from naturally weathered plastic waste and identified the potential key PE degradation enzymes.

Therapy discontinuation of systemic glucocorticoid treatment for pemphigus remains uncertain at the clinical end point of complete remission. The objective of this study was to identify the factors associated with achieving complete remission off therapy (CROT) and analyze the occurrence of relapse after therapy discontinuation. A retrospective cohort study was conducted at the Department of Dermatology of Peking University First Hospital.

Objective: The leukemia cells from patients with T-cell acute lymphoblastic leukemia (T-ALL) were inoculated into NCG mice to establish a stable human T-ALL leukemia animal model.
Methods: Leukemia cells from bone marrow of newly diagnosed T-ALL patients were isolated, and the leukemia cells were inoculated into NCG mice via tail vein. The proportion of hCD45 positive cells in peripheral blood of the mice was detected regularly by flow cytometry, and the infiltration of leukemia cells in bone marrow, liver, spleen and other organs of the mice was detected by pathology and immunohistochemistry.
Background: Mendelian disorders of cornification (MeDOC) are a group of heterogeneous genodermatoses with different genetic bases. The pathogenesis of a substantial group of MeDOC remains to be elucidated.
Objectives: To identify a new causative gene and the pathogenesis of a previously undescribed autosomal-dominant cornification disorder.
