Background And Objective: Limited information is available on the pharmacokinetics of rifampicin (RIF) along with that of its active metabolite, 25-deacetylrifampicin (25-dRIF). This study aimed to analyse the pharmacokinetic data of RIF and 25-dRIF collected in adult patients treated for tuberculosis.
Methods: In adult patients receiving 10 mg/kg of RIF as part of a standard regimen for drug-susceptible pulmonary tuberculosis enrolled in the Opti-4TB study, plasma RIF and 25-dRIF concentrations were measured at various occasions.
Introduction: Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is a severe hypersensitivity reaction rarely documented in patients with multiple myeloma (MM).
Methods: In our retrospective study of 108 newly diagnosed MM (NDMM) patients from January 2021 to October 2023, we identified four cases of DRESS. The clinical characteristics such as clinical manifestations, laboratory results, treatment and outcome were analyzed.

Introduction: Hypericin (HP), a natural photosensitizer, has demonstrated great efficacy in photodynamic therapy (PDT) for cancer treatment. In addition to the induction of apoptosis and necrosis through reactive oxygen species (ROS) generation, the therapeutic mechanisms and targets of PDT-HP remain unknown.
Objectives: To investigate the direct targets and mechanisms of action of photoactivated hypericin in the inhibition of triple-negative breast cancer (TNBC).

IL-21 is a type I cytokine that is produced by activated CD4 T cells and has a significant impact on the growth, survival, and functional activation of B lymphocytes. While IL-21 has been identified in several teleost fish species, its function and associated mechanisms focus on teleost fish B cells remain largely unknown. In this study, we aimed to investigate the effects of IL-21 (OnIL-21) on IgM B cells from Nile tilapia (Oreochromis niloticus), as well as the intracellular signaling transduction pathway involved.

Background: The common drugs used for the treatment of Newly Diagnosed Multiple Myeloma (NDMM) include bortezomib and lenalidomide, but the adverse effects of lenalidomide cannot be ignored, especially when it is used in the initial therapy.
Methods: This retrospective study evaluated the efficacy and safety of a modified DVD regimen (pegylated liposomal doxorubicin, bortezomib, and dexamethasone) followed by lenalidomide in the treatment of NDMM. A total of 40 NDMM patients were treated with a reduced dose of pegylated liposomal doxorubicin (20 mg/m) on day 1, subcutaneous bortezomib (1.
