    Abstract Objective: To investigate the clinicopathological features, diagnosis, differential diagnosis, treatment and prognosis of myxoid liposarcoma (MLPS)of the testis.
    Methods: We observed the clinicopathological and immunophenotypic characteristics of primary MLPS of the testis in a male patient and reviewed the relevant literature.
    Results: The tumor was located in the right testicular parenchyma, of multi-nodular growth microscopically. The tumor cells were stellate, fusiform, foamy and signet ring-like, with abundant mucus and a network of fine branched or plexiform capillaries in the stroma. Immune phenotype-related findings included positive p16 and H3K27ME3 tumor cells and CD34 vascular network, negative CD99, CK, Desmin, FLI agreed-1, S-100, SMA, STAT6, TFE3, α-inhibin and SOX1, and a Ki-67 proliferation index of about 15%.
    Conclusion: Primary MLPS of the testis is rare, which needs to be differentiated from myxosarcoma, rhabdomyosarcoma, myxoma, spindle cell or pleomorphic liposarcoma, and lipophiloma. Immunohistochemical markers Vimentin, s-100 and CD34 can assist in the diagnosis of the tumor.

    Abstract Objective To perform primary culture of glomerular mesangial cells, identify them from a mouse model of spontaneous lupus nephritis model and explore the optimal conditions for these procedures. Methods Nine control ICR mice and nine model MRL/lpr mice with spontaneous lupus nephritis were tested for autoantibodies using ELISA and urine protein was detected by bicinchoninic acid (BCA) assay at 12, 14 and 18 weeks of age. HE and Masson staining were used to observe the pathological changes of mice with lupus nephritis. Glomeruli were isolated using a cell sieve, while primary culture of glomerular mesangial cells was performed using the eugenic selection method. Glomerular mesangial cells of the MRL/lpr mice were identified based on cell morphology and immunocytochemical staining of α-smooth muscle actin and nephrin. Results In the model group, levels of anti-nuclear antibody and anti-double-stranded DNA antibodies significantly increased. Urine protein levels also increased significantly at 14 and 18 weeks of age. HE and masson staining of kidney tissue revealed pathological changes associated with lupus nephritis in the MRL/lpr mice from 12 weeks of age. Twenty-five days after seeding of the glomerular mesangial cells, those from the MRL/lpr mice gradually covered the bottom of the culture flasks, appearing star-shaped and fusiform by phase contrast microscopy. Immunocytochemistry showed that these cells were α-smooth muscle actin-positive and nephrin-negative, thus ruling out other glomerular intrinsic cells. Conclusion The primary culture of glomerular mesangial cells from mice with spontaneous lupus nephritis is developed and characterized.

    Abstract MOTIVATION: Amphibians are a diverse vertebrate group with more than 8,000 species, which is an important part of major terrestrial and freshwater ecosystems. Unfortunately, amphibians are experiencing a worldwide population decline. Trait information is important for understanding the causes of endangerment. Additionally, such information is essential for ecological and evolutionary studies using trait‐based approaches. However, such data are scarcer for amphibians than for any other terrestrial vertebrate groups. To fill this gap, we collected morphological traits of global amphibians available from the literature and compiled a database to facilitate future studies. MAIN TYPES OF VARIABLES CONTAINED: Forty‐two morphological traits of Anura, 27 morphological traits of Caudata and 37 morphological traits of Gymnophiona. SPATIAL LOCATION AND GRAIN: Global. MAJOR TAXA: Amphibia. LEVEL OF MEASUREMENT: Species. SOFTWARE FORMAT: .csv.

    Abstract Purpose: Chemoresistance is a major challenge for acute lymphoblastic leukemia (ALL) treatment. Cysteine-rich protein 61 (Cyr61) plays an important role in drug resistance modulation of tumor cells, and Cyr61 levels are increased in the bone marrow of patients with ALL and contribute to ALL cell survival. However, the effect of Cyr61 on B cell acute lymphoblastic leukemia (B-ALL) cell chemosensitivity and the regulatory mechanisms underlying Cyr61 production in bone marrow remain unknown.
    Methods: Nalm-6 and Reh human B-ALL cell lines were used in this study. Cyr61 levels were assessed using quantitative real-time PCR (qRT-PCR), western blot analysis, and enzyme-linked immunosorbent assay. The effect of Cyr61 on B-ALL cell chemosensitivity to daunorubicin (DNR) was evaluated using cell viability and flow cytometry analyses. The regulatory mechanisms of Cyr61 production in bone marrow were examined using qRT-PCR and western blot analysis.
    Results: Cyr61 knockdown and overexpression increased and decreased the chemosensitivity of B-ALL cells to DNR, respectively. Cyr61 attenuated chemotherapeutic drug-induced apoptosis by upregulating B cell lymphoma-2. Notably, DNR induced DNA damage response and increased Cyr61 secretion in B-ALL cells through the ataxia telangiectasia mutated (ATM)-dependent nuclear factor kappa B pathway.
    Conclusion: DNR induces Cyr61 production in B-ALL cells, and increased Cyr61 levels reduce the chemosensitivity of B-ALL cells. Consequently, targeting Cyr61 or related ATM signaling pathway may present a promising treatment strategy to enhance the chemosensitivity of patients with B-ALL.

    Abstract ZVI@C-MP is a novel composite particle consisting of zero-valent iron (ZVI) enclosed within a carbon shell. The purpose of this composite material is to enhance the anaerobic treatment of wastewater containing chloramphenicol (CAP). This approach aims to address the initial challenge of excessive corrosion experienced by ZVI, followed by its subsequent passivation and inactivation. ZVI@C-MP was synthesized through a hydrothermal process and calcination, with montmorillonite as binder, it exhibits stability, iron-carbon microelectrolysis (ICME) properties, and strong adsorption for CAP. Its ICME actions include releasing iron ions (0.70 mg/L) and COD (11.3 mg/L), generating hydrogen (3.82%), and raising the pH from 6.30 to 7.71. With minimal structural changes, it achieved release equilibrium. ZVI@C-MP boasts high removal efficiency of CAP (98.96%) by adsorption, attributed to surface characteristics (surface area: 167.985 m

    Abstract Breast cancer (BC) is one of the most dangerous malignant diseases in females. However, the reliable serum biomarkers of BC still need to be explored. Chemerin levels have been found to be associated with different types of cancer. This study aimed to evaluate the role of serum chemerin as a biomarker of BC diagnosis, as well as the correlation between serum chemerin levels and clinicopathological features. The serum from 248 BC patients, 30 breast benign tumor patients, and 103 healthy controls were collected and serum chemerin levels were determined with enzyme-linked immunosorbent assay. We found that serum levels of chemerin in BC patients were higher than those in healthy control individuals (p < 0.05). The area under the ROC curve (AUC) for chemerin, CA15-3 and CEA was 0.703, 0.662 and 0.581, respectively, in distinguishing between breast cancer patients from healthy individuals, and the chemerin cutoff value was 100.327 ng/ml with a sensitivity of 56.60% and a specificity of 98.10%. The AUC for chemerin + CA15-3 was 0.822, which was higher than that for chemerin + CEA and CEA + CA15-3. Moreover, serum levels of chemerin were significantly associated with histologic grade, Ki67 expression, and menopausal status. However, no significant association was found between serum levels of chemerin and age, tumor size, metastase, ER status, PR status, and HER-2 status. Overall, our study suggested that the combination of chemerin with CA15-3 achieves relatively better diagnostic performance in the breast cancer. Elevated serum chemerin is associated with Ki67 expression levels and histologic grade.
