Dedifferentiated liposarcoma (DDLPS) is one of the four subtypes of liposarcomas; it is characterized by the amplification of the 12q13-15 region, which includes MDM2 and CDK4 genes. DDLPS has an extremely high local recurrence rate and is refractory to chemotherapy and radiation, which leads to poor prognosis. Therefore, a novel therapeutic strategy should be urgently established for improving the prognosis of DDLPS. Although patient-derived cell lines are important tools for basic research, there are no DDLPS cell lines available from public cell banks. Here, we report the establishment of a novel DDLPS cell line. Using the surgically resected tumor tissue from a patient with DDLPS, we established a cell line and named it NCC-DDLPS1-C1. The NCC-DDLPS1-C1 cells contained 12q13-15, 1p32, and 1q23 amplicons and highly expressed MDM2 and CDK4 proteins. NCC-DDLPS-C1 cells exhibited constant growth, spheroid formation, aggressive invasion, and tumorigenesis in mice. By screening a drug library, we identified that the proteasome inhibitor, bortezomib, had inhibitory effects on the proliferation of NCC-DDLPS1-C1 cells. We concluded that the NCC-DDLPS1-C1 cell line may serve as a useful tool for basic and pre-clinical studies of DDLPS.Intracystic papillary neoplasm (ICPN) of the gallbladder is a rare clinicopathological entity with a wide range of malignant potentials. Here, we report a case of mucin-producing gallbladder carcinoma possibly derived from ICPN. A 78-year-old female patient was referred to our hospital for examination of jaundice. Abdominal CT showed dilated biliary trees and a contrast-enhanced large polypoid mass in the gallbladder. Duodenoscopy showed a large amount of mucin extravasating from the ampulla of Vater. Bile cytology showed no evidence of malignancy. Under the diagnosis of mucin-producing gallbladder tumor, we performed laparoscopic cholecystectomy. Macroscopically, there was a large papillary tumor throughout the entire gallbladder mucosa. Pathological examinations showed a gallbladder adenocarcinoma localized to the mucosa in association with ICPN. Immunohistochemical analysis of the tumor revealed positive staining for MUC2 and MUC5AC but negative for MUC1 and MUC6, suggestive of the intestinal type.Chlortetracycline (CTC) has been widely used in veterinary medicine in recent years, which has resulted in severe environmental issues due to its low degradation rate and high risk to induce antibiotic resistance bacteria and genes. In previous studies, CTC could be efficiently degraded by Trichoderma harzianum LJ245. Nevertheless, the strain itself suffers from relatively poor adaptability due to the limited number of spores produced. In this paper, ultraviolet (UV) mutagenesis was conducted on LJ245, and various mutants with high sporulation rate were generated to expand the environmental adaptability and enhance CTC degradation. An OmniLog-based method, where 95 types of carbon sources were applied, was first proposed to acquire the carbon metabolic profile of the strains. Several controlled experiments were performed to evaluate the impact of co-substrate metabolism on strain growth, CTC biodegradation, and metabolites biotoxicity removal. The result shows that produced mutants could significantly broaden the carbon metabolic profile and expand the environmental adaptability compared to the original LJ245, where the mutants obtained remarkable increase in total number of usable carbon sources. Meanwhile, as the sole carbon source, CTC could not be fully degraded by the strains. However, the use of co-metabolism could considerably enhance CTC degradation and completely remove CTC degradation products biotoxicity by all strains.  https://www.selleckchem.com/products/BIBF1120.html  Specifically, amino acids and carboxylic acids had the best performance on both strain growth and CTC degradation among all carbon source categories. The results can be applied to the biodegradation treatment of CTC in solid residue, waste water and other environments.The aim of the study was to investigate the relationship between fear of childbirth (FOC) and psychological (PWB) and spiritual well-being (SWB) in pregnant women. Descriptive and relational study was conducted with 338 pregnant women in Turkey. Information form, Wijma Delivery Expectancy/Experience Questionnaire-A, Spiritual Well-Being Scale and Psychological Well-Being Scale were used for data collection. There was a negative correlation between SWB and PWB and FOC in pregnant women. SWB explained 18% of the variance related to FOC which increased to 24% with PWB. SWB was a partial mediating variable in PWB and FOC relationship. PWB and SWB of pregnant women should be evaluated in order to reduce FOC. PWB and SWB of pregnant women should be evaluated in order to reduce FOC.Microsatellite instability (MSI) is an effective biomarker for diagnosing Lynch syndrome (LS) and predicting the responsiveness of cancer therapy. MSI testing is conventionally performed by capillary electrophoresis, and MSI status is judged by visual assessment of allele size change. Here, we attempted to develop a quantitative evaluation model of MSI using next-generation sequencing (NGS). Microsatellite markers were analyzed in tumor and non-tumor tissues of colorectal cancer patients by NGS after a single multiplex polymerase chain reaction amplification. The read counts corresponding to microsatellite loci lengths were calculated independently of mapping against a reference genome, and their distribution was digitized by weighted mean. Weighted mean differences between tumor and non-tumor samples with different MSI status were assessed, and cut-off values for each marker in the discovery cohort were determined. Each microsatellite maker was defined as unstable if the weighted mean difference was greater than the cut-off value. In the discovery cohort, the evaluation model demonstrated sensitivity and specificity of 100% for all markers. In the validation cohort, MSI status determined by the new model was consistent with the outcome of the conventional method in 29/30 cases (97%). The single inconsistent case was classified as low-frequency MSI by the conventional method but considered MSI-high by NGS. Genetic testing for mismatch repair genes revealed a pathogenic variant in MSH6 in the discordant case. We successfully developed a quantitative evaluation method for determining MSI status using NGS. This is a robust and sensitive method and could improve LS diagnosis.
