Project description:The aim of the experiment is to compare the transcriptional profile of MEi (mesenchymal-like mucoepidermoid tumor) cells with BM-MSCs (bone marrow mesenchymal stromal cells). The MEi cells were isolated from a mucoepidermoid tumor from the trachea. BM-MSCs were isolated from bone marrow of healthy donors. The MEi cells are a new cell line established by Dr Lim Mei Ling.
Project description:5 rats were offered food containing 40mM Li/Kg dry weight for 4 weeks, and 5 control rats obtained standard food. The RNA from the inner medulla of the Li-treated rats was labeled red (channel 1), and from the control rats labeled green (channel 2). The samples from Li-treated rats 1+2 and control rats 1+2 were hybridized to array Li-NDI 1. The samples from Li-treated rats 3+4 and control rats 3+4 were hybridized to array Li-NDI 2. The samples from Li-treated rat 5 and control rat 5 were hybridized to array Li-NDI 3. Keywords: parallel sample

Project description:Mei-yu is an important weather phenomenon in the middle-lower Yangtze River valley (YRV) region. This study investigates the changes in the characteristics of Mei-yu under global warming and the potential reasons based on observation and reanalysis data during 1961-2022. Notable increasing long-term trends are detected in the number of days without rainfall (NDWOR), the intensity of rainfall events, and the frequency and intensity of extreme precipitation events (EPEs) in the YRV region during the Mei-yu period (15 June-10 July) over past decades. The increasing trend in NDWOR is attributed to decreased relative humidity over land surface and a longer time for the air to be replenished with moisture after rainfall events in a warming climate. The increasing trends in the intensity of rainfall events and frequency/intensity of EPEs are attributed to the strengthened transient water vapor convergence and convection in the atmosphere under global warming. Furthermore, the response of Mei-yu to 2°C of global warming with respect to the pre-industrial climate is analysed using CMIP6 models. The results suggest that the NDWOR, intensity of rainfall events and frequency of EPEs will increase in the YRV region during the Mei-yu period under the 2°C warming scenario, which implies a more challenging climate risk management in the future. Overall, the intensity of rainfall events during the Mei-yu period has the most significant response to climate change in observations and projections. The model results have a relatively large uncertainty.
Project description:The study involves trabscriptome analysis using RNA-seq of stable transgenic DLD-1 cancer cell line, which express Tet-inducible combinations of mei-cohesin subunits. The following combinations of mei-cohesin genes were expressed in DLD-1 : STAG3+SMC1beta, STAG3+SMC1beta+REC8, and STAG3+SMC1beta+RAD21L The goal of the study was to investigate the RNA transcriptional response to the induction of mei-cohesin subunits in somatic cells using Tet-on inducible transgenes activated by an rtTA transgene and doxyciline.
Project description:The study involved chromatin IP analyzed by high-throughput sequencing analysis using stable transgenic human cancer cell lines, which express Tet-inducible combinations of mei-cohesin subunits. The following individual genes and combinations of mei-cohesin subunits were expressed in human cells : STAG3, SMC1beta, STAG3+SMC1beta+REC8, and STAG3+SMC1beta+RAD21L The goal of the study was to investigate the epigenomic properties of somatic cells in response to the induction of mei-cohesin subunits using Tet-on inducible transgenes activated by an rtTA transgene and doxycicline.
Project description:Colonoscopy aims to investigate the entire colon by advancing the colonoscope tip from the rectum to the cecum, a process called cecal intubation. Cecal intubation may be difficult for different reasons, and features of the colonoscope and the use of imaging devices may influence the success rate. We want to compare the performance of a new colonoscope with novel features including gradual stiffness with that of a colonoscope supplied with a magnetic endoscope imaging (MEI) device. The hypothesis is that the performance of the new instrument is non-inferior to the MEI system.
