Myeloma cell-derived CXCL7 facilitates proliferation of tumor cells and occurrence of osteolytic lesions through JAK/STAT3 pathway.

Osteolytic lesions and pathological fractures are hallmark manifestations of multiple myeloma (MM), profoundly influencing the quality of life and self-care ability of MM patients. By analyzing transcriptome data and single-cell RNA-seq data from our center and the GEO database, a subset of MM cells with high expression levels of chemokine CXCL7 was identified. This subset of MM cells possesses a high capacity for proliferation and activation of osteoclast signaling pathway.

An endogenous aryl hydrocarbon receptor ligand dysregulates endothelial functions, transcriptome, and phosphoproteome.

We have reported that an endogenous aryl hydrocarbon receptor (AhR) ligand, 2-(1'H-indole-3'-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE), inhibits functions of human umbilical vein endothelial cells (HUVECs) and induces preeclampsia (PE)-like symptoms in rats. Herein, we tested the hypothesis that ITE impairs endothelial functions via disturbing transcriptome and phosphoproteome in HUVECs. We measured AhR activity in human maternal and umbilical vein sera from PE and normotensive (NT) pregnancies.

Isovitexin targets SIRT3 to prevent steroid-induced osteonecrosis of the femoral head by modulating mitophagy-mediated ferroptosis.

The death of osteoblasts induced by glucocorticoid (GC)-mediated oxidative stress plays a crucial role in the development of steroid-induced osteonecrosis of the femoral head (SIONFH). Improving bone formation driven by osteoblasts has shown promising outcomes in the prognosis of SIONFH. Isovitexin has demonstrated antioxidant properties, but its therapeutic effects on GC-induced oxidative stress and SIONFH remain unexplored.

A novel spectroscopy-deep learning approach for aqueous multi-heavy metal detection.

Addressing heavy metal contamination in water bodies is a critical concern for environmental scientists. Traditional detection methods are often complex and costly. Recent advancements in artificial intelligence (AI), particularly machine learning (ML) and deep learning (DL), have shown significant potential in analytical chemistry.

The pathomechanism of bone marrow edema in the femoral head necrosis with pericollapse stage.

Bone marrow edema (BME), a notable manifestation during the progression of osteonecrosis of the femoral head (ONFH), exhibits significant associations with femoral head collapse, pain, and prognosis, howeverits' pathogenesis remains underexplored. In this study, specimens from patients undergoing total hip arthroplasty (THA) were analyzed. The results revealed significantly higher Visual Analog Scale (VAS) scores and CT low-density area ratio in the BME group compared to the control group.

Advancements and challenges in microplastic detection and risk assessment: Integrating AI and standardized methods.

Microplastics (MPs) pose significant threats to ecosystems and human health due to their persistence and widespread distribution. This paper provides a comprehensive review of sampling methods for MPs in aquatic environments, soils, and biological samples, assessing pre-treatment procedures like digestion and separation. It examines the application and limitations of identification techniques, including microscopic observation, spectroscopic analysis, and thermal analysis.

Glutamic-pyruvic transaminase 1 deficiency-mediated metabolic reprogramming facilitates colorectal adenoma-carcinoma progression.

The tumorigenesis of colorectal cancer (CRC) often follows the normal-adenoma-carcinoma (N-A-C) sequence. However, the molecular mechanisms underlying colorectal adenoma carcinogenesis remain largely unknown. Here, we analyzed transcriptomic profile changes in normal, advanced adenoma, and carcinoma tissues from patients with CRC, revealing that glutamic-pyruvic transaminase 1 () in colorectal tissues was down-regulated during the N-A-C process and correlated with poor CRC prognosis.

An endogenous aryl hydrocarbon receptor ligand induces preeclampsia-like phenotypes in rats.

Preeclampsia (PE) is a hypertensive disorder during human pregnancy. Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor. Exogenous and endogenous AhR ligands can induce hypertension in male rats and mice.

Light-chain amyloidosis with concomitant symptomatic myeloma (CRAB-SLiM features): clinical characteristics, cytogenetic abnormalities, and outcomes.

Background: Patients with light-chain (AL) amyloidosis and concomitant multiple myeloma (MM) are known to have a worse prognosis, while the prognostic implication of cytogenetic abnormalities (CA) and optimal treatment schemes are not well-established. By comparing patients with MM or AL amyloidosis (AL) alone, this study aimed to evaluate the clinical characteristics, CA, and outcomes of patients with AL amyloidosis and concomitant symptomatic MM (MM-AL) and sought to provide evidence for their management.

Methods: In total, 915 consecutive patients with newly diagnosed AL amyloidosis or MM were retrospectively analyzed.

Psychological Risk Factors on Hematopoietic Stem Cell Transplantation Patients: Insights From National Readmission Database Analysis.

Background: Psychosocial risk factors (PSRFs) have emerged as important nontraditional risk factors for poor medical outcomes but have not been well-studied in the field of hematopoietic stem cell transplantation (HSCT).

Objectives: In this study, we retrospectively examined in-hospital and short-term outcomes in patients with PSRFs who underwent HSCT.

Methods: We used the National Readmission Database (NRD) to identify patients who underwent HSCT between 2011 and 2020.

An intelligent spectral identification approach for the simultaneous detection of endocrine-disrupting chemicals in aquatic environments.

With the rapid progression of industrialization, the application and release of endocrine disruptors (EDCs), including bisphenol A (BPA), octylphenol and nonylphenol have significantly increased, presenting substantial health hazards. Conventional analytical techniques, such as high-performance liquid chromatography and gas chromatography-mass spectrometry, are highly sophisticated but suffer from complex procedures and high costs. To overcome these limitations, this study introduces an innovative spectral methodology for the simultaneous detection of multiple aquatic multicomponent EDCs.

Early minimal residual disease eradication in light chain amyloidosis generates deeper and faster cardiac response.

Minimal residual disease (MRD) is of growing interest in light chain (AL) amyloidosis and is associated with higher rates of cardiac response. A new graded cardiac response criteria has been proposed for better assessment of cardiac improvement. We evaluated MRD status in 63 patients with cardiac AL amyloidosis using next generation flow cytometry (sensitivity ≥ 1*10) within four cycles after treatment initiation and cardiac response kinetics.

Maintenance therapy promotes profound organ and haematologic response in light-chain amyloidosis patients not undergoing autologous stem cell transplantation.

Background: Evidence on maintenance therapy following frontline induction is sparse in primary light-chain amyloidosis (AL), especially for those who do not undergo autologous haematopoietic stem cell transplantation (ASCT).

Methods: We enrolled primary AL patients who achieved at least haematologic very good partial response (VGPR) by the 4th month at the frontline from December 2008 to June 2023 at Zhongshan Hospital, Fudan University. Those who followed maintenance therapy were identified as the maintenance group ( = 44), whereas those entering the observational phase were classified as the observational group ( = 24).

Microbial diversity across tea varieties and ecological niches: correlating tea polyphenol contents with stress resistance.

Introduction: Microorganisms exhibit intricate interconnections with tea plants; however, despite the well-established role of microorganisms in crop growth and development, research on microbes within the tea plant remains insufficient, particularly regarding endophytic microorganisms.

Methods: In this study, we collected samples of leaves and rhizosphere soils from 'Zhuyeqi', 'Baojing Huangjincha#1', 'Baiye#1', and 'Jinxuan' varieties planted.

Results: Our analyses revealed significant variations in tea polyphenol contents among tea varieties, particularly with the 'Zhuyeqi' variety exhibiting higher levels of tea polyphenols (>20% contents).

Chromosomal instability is associated with prognosis and efficacy of bevacizumab after resection of colorectal cancer liver metastasis.
