Clinical updates of B‑cell maturation antigen‑targeted therapy in multiple myeloma (MM) and relapsed/refractory MM (Review).

Despite significant progress in managing multiple myeloma (MM) in recent years, certain patients still have a short duration of therapeutic response, often relapsing within 18 months. These patients typically have high‑risk genetic mutations and may show little to no response to current treatments, highlighting the need for further exploration of optimal therapeutic targets for MM. B‑cell maturation antigen (BCMA), highly expressed in mature B lymphocytes and plasma cells and upregulated in MM, is a promising therapeutic target.

In this study, we explored the effect of nebivolol on cell proliferation and cell activity in melanoma in vitro and the potential antimelanoma mechanism of nebivolol through a series of experiments, including the analysis of the effects with regard to cell apoptosis and metastasis.

Structural characterization and immunomodulatory activity of a water-soluble polysaccharide from Poria cocos.

In order to investigate the structural characteristics and immunomodulatory effects of Poria cocos polysaccharides, a water-soluble homogeneous polysaccharide (PCP-2) was isolated by water extraction and alcohol precipitation and further purified by Cellulose DEAE-52 and Sephacryl S-100HR column chromatography. PCP-2 is a heteropolysaccharide composed of glucose, galactose, mannose, and fucose in a molar ratio of 42.0: 35.

Repurposing of Antidiarrheal Loperamide for Treating Melanoma by Inducing Cell Apoptosis and Cell Metastasis Suppression and .

Background: Melanoma is the most common skin tumor worldwide and still lacks effective therapeutic agents in clinical practice. Repurposing of existing drugs for clinical tumor treatment is an attractive and effective strategy. Loperamide is a commonly used anti-diarrheal drug with excellent safety profiles.

Advances in the Study of Plant-Derived Vesicle-Like Nanoparticles in Inflammatory Diseases.

All humans are universally affected by inflammatory diseases, and there is an urgent need to identify new anti-inflammatory drugs with good therapeutic benefits and minimal side effects to the organism. Recently, it has been found that plant-derived vesicle-like nanoparticles (PDVLNs) have good biocompatibility, with their active ingredients exhibiting good therapeutic effects on inflammation. They can also be used as drug carriers for targeted delivery of anti-inflammatory drugs.

Study on Optimal Extraction and Hypoglycemic Effect of Quercetin.

Quercetin was extracted from L. through biphasic acid hydrolysis to investigate its potential as a suppressor of dipeptidyl peptidase IV (DPP-IV) and its hypoglycemic effect in type 2 diabetic mice. The extraction procedure was optimized utilizing the response surface method (RSM) in a single-factor experimental setting.

Functional plasticity of neutrophils after low- or high-dose irradiation in cancer treatment - A mini review.

Over the last several decades, radiotherapy has been considered the primary treatment option for a broad range of cancer types, aimed at prolonging patients' survival and slowing down tumor regression. However, therapeutic outcomes of radiotherapy remain limited, and patients suffer from relapse shortly after radiation. Neutrophils can initiate an immune response to infection by releasing cytokines and chemokines to actively combat pathogens.

Effects of wearable physical activity tracking for breast cancer survivors: A systematic review and meta-analysis.

Purpose: Breast cancer is the most common cancer type worldwide, with its survivors often experiencing physical and psychosocial health problems. Wearable device use is an innovative and effective way to promote physical activity and improve health-related outcomes in breast cancer survivors; however, the current evidence is unclear. We aimed to determine the effects of wearable devices on physical activity and health-related outcomes in breast cancer survivors.

Drug Value of Drynariae Rhizoma Root-Derived Extracellular Vesicles for Neurodegenerative Diseases Based on Proteomics and Bioinformatics.

Extracellular vesicles (EVs) are nano-sized membrane vesicles released by various cell types. Mammalian EVs have been studied in-depth, but the role of plant EVs has rarely been explored. For the first time, EVs from roots were isolated and identified using transmission electron microscopy and a flow nano analyzer.

Endoscopic- versus x-ray-guidance for placement of nasojejunal tubes in critically ill patients: a systematic review and meta-analysis of randomized controlled trials.

Nasojejunal tubes (NJTs) are increasingly used in critically ill patients. NJT insertion with endoscopic- or x-ray-guidance can be achieved with success rates above 90%. This systematic review and meta-analysis of randomized controlled trials (RCTs) compares the efficiency and safety of these two methods in critically ill patients.

Gene expression patterns associated with tumor-infiltrating CD4+ and CD8+ T cells in invasive breast carcinomas.

Background: Breast carcinoma is one of the most common tumors in women. The immune microenvironment, especially T cell infiltration, is related to the occurrence and prognosis of breast carcinoma.

Objective: This study investigated the gene expression patterns associated with tumor-infiltrating CD4+ and CD8+ T cells in invasive breast carcinomas.

Single-Cell Analysis Reveals Characterization of Infiltrating T Cells in Moderately Differentiated Colorectal Cancer.

Objective: This study aimed to characterize the tumor-infiltrating T cells in moderately differentiated colorectal cancer.

Methods: Using single-cell RNA sequencing data of isolated 1632 T cells from tumor tissue and 1252 T cells from the peripheral blood of CRC patients, unsupervised clustering analysis was performed to identify functionally distinct T cell populations, followed by correlations and ligand-receptor interactions across cell types. Finally, differential analysis of the tumor-infiltrating T cells between colon cancer and rectal cancer were carried out.

Fluid Retention Caused by Rosiglitazone Is Related to Increases in AQP2 and ENaC Membrane Expression.

Peroxisome proliferator activated receptor- (PPAR) is a ligand-activated transcription factor of the nuclear hormone receptor superfamily. The decreased phosphorylation of PPAR due to rosiglitazone (ROS) is the main reason for the increased insulin sensitivity caused by this antidiabetic drug. However, there is no clear evidence whether the nuclear translocation of p-PPAR stimulated by ROS is related to fluid retention.
