Project description:Transcriptomic profiling of T. chinensis and T. ramosissima shows responses due to water deficit that are common between the two species and differences that shows their invasiveness originating from southern and northern united states. Several drought related genes that were up-regulated common in both species and transcription factors unique to T.chinensis and T. ramosissima were also found. Gene Ontology classification shows similar functional categories in both the species. Differences in two species due to water deficit were also illustrated in networks constructed from genes enriched in biological processes and molecular functions.

Project description:Open chromatin provides access to a wide spectrum of DNA binding proteins for DNA metabolism processes such as transcription, repair, recombination, and replication. In this regard, open chromatin profiling has been widely used to identify the location of regulatory regions, including promoters, enhancers, insulators, silencers, replication origins, and recombination hotspots. For a quantitative getic analysis of chromatin regulation, we generated open chromatin maps of 100 yeast samples including the parental strains (BY and RM, and two replicates for each) and their descendants by using the FAIRE-seq technique Open chromatin in two parental strains and 94 segregants of their crossing
Project description:Experiment to identify genes for responding to water stress in the moss Physcomitrella patens using various available water stresses such as mannitol, NaCl, and drought. Treatments were carried out on duplicate tissue samples. RNA isolated independently from each tissue sample and monitored for stress/hormone induction of the PpLea-2 gene by Northern blot hybridisation. Duplicate RNA samples bulked for Cy3/Cy5 labelling and array hybridisation. Two microarrays per treatment hybridised using a reciprocal dye swap (control -vs- treatment).
Project description:Investigation of whole genome gene expression level changes in the youngest expanded leaves of open-pollinated Golden Delicious seedlings either sprayed with reverse osmosis water or acibenzolar-S-methyl (ASM). Treatment was performed by spraying sprayed to runoff (with a pressurized hand sprayer) with the commercial product Bion 50 WG (Syngenta, Basel, Switzerland; 50% of ASM) prepared in reverse osmosis water at a final concentration of 0.4 g/L. The youngest developped leaf of each seedling was sampled 3 days after the treatment.
Project description:Water immersion insertion has been documented to decrease procedure-related discomfort during colonoscopy. There was used warm water infusion for colonoscope insertion in most of the water immersion colonoscopy trials.
The investigators have been using room temperature water (20-24°C) for water immersion and the investigators did not notice any drawback of it. In our opinion, it is simpler and cheaper option for water immersion colonoscopy and proof of its efficacy and safety could support the use of water immersion technique in routine practice.
The primary endpoint is cecal intubation time and the investigators suppose that the use of warm water infusion does not shorten it significantly. Patient comfort during colonoscope insertion, water consumption, length of the scope while reaching the cecum, need for external compression, need for positioning of the patient and endoscopist´s difficulty with colonoscopy will be also assessed.
Project description:The DNA microarray was employed in this study to investigate the gene expression profiles of Escherichia coli treated by an oil-in-water (o/w) microemulsion, in order to better understand the antimicrobial mechanism of the microemulsion as a promising food-grade antimicrobial system. 5,440 open reading frames (ORFs) of E. coli were investigated.
Project description:Micrococcal nuclease was used to digest mESC nuclei under a mild digestion condition to release the relatively open chromatin, and under an extensive digestion condition to release the genome chromatin. By comparing the genome distribution of mono-nucleasome under these two conditions, open chromatin regions were detected. One mild digestion and one extensive digestion was applied to the mESC cells, followed by sequencing.
