Project description:To improve post-operative recovery, medical device was developed combining low-pressure pneumoperitoneum and heated and humidified Carbon Dioxide (95˚F & 95% RH) during laparoscopic surgery to reduce the harmful effects of cold/dry insufflation.
A double-blind, prospective, randomized, controlled, monocentric trial is designed in the aim to assess the impact of low-pressure pneumoperitoneum with warm and humidified gaz on post-operative pain at 24 hours without taking opioids. It is compared with low-pressure laparoscopy with cold and dry gaz in patients undergoing colorectal surgeries.

Project description:CAMTA3 is known to be involved in regulation of induction of early cold-responsive genes, CBF1 and CBF2 at cold conditions and of suppression of SA production at warm temperature. Considering a functional redundancy of CAMTA family members in both warm and cold conditions, high-order of camta mutants, camta double and triple mutants, were generated and used to determined the effects of their regulation using microarray analysis. Global gene expression profile of WT and camta mutants was compared with the plants at warm temperature or at cold condition, 4°C for 24 hrs.

Project description:St (common potato) is a freezing sensitive species unable to cold acclimate. The close wild relative Sc is freezing tolerant and able to cold acclimate. Here we compare the cold transcriptome of these two species with different levels of freezing tolerance. We also identify the putative CBF regulons by comparing the transcriptomes of wild type plants with that of 35S::AtCBF3 transgenic lines in both species. Plants were grown in 16:8 photoperiod. Eight hours after dawn, plants were either transfered to cold or kept in the warn. Wild type S. tuberosum and S. commersonii were grown at 2oC for 2h, 24h and 7 days. Wild type plants grown under warm temperatures for 2h was used as control for 2h cold samples; wild type warm grown plants for 24h were used as controls for 24h and 7 days cold samples. Under warm conditions, S. commersonii 35S::AtCBF3 lines were compared to S. commersonii wild type plants (same thing was done for S. tuberosum).

Project description:In DCD organ donation one of the significant problems for the organ is the inflammatory response due to ischaemia reperfusion injury caused by warm ischaemia prior to retrieval followed by warm reoxygenation upon transplantation. We developed a model where a DCD kidney was retrieved and preserved using hypothermic machine perfusion with cold University of Wisconsin solution with/without the addition of heparinoids low molecular weight heparin and pentosan polysulfate (PPS) followed by warm oxygenated perfusion with modified Krebs-Henseleit buffer to simulate early ischaemia reperfusion injury (IRI). The donor rats consisted of a control group cold perfusion group compared to warm perfusion and groups treated with either low molecular weight heparin or PPS to assess their activity in ameliorating IRI. We used equimolar pooled RNA samples from each group to perform an exploratory microarray experiment

Project description:Transcriptomic study of the impact of osmopriming on rape seeds (Brassica napus L.; cv 'Libomir') during priming process and after germination. The assays were replicated twice on two independent priming and germination experiments. Seeds were osmoprimed in PEG solution (-1.2 MPa osmotic potential) during 7 days, dried to initial moisture content and then germinated for 7 hours on water. The analysis during different phases of priming procedure (soaking and drying), after whole osmopriming process and germination were done. 10 samples, four condition experiment; non dried primed seeds (Pnd) vs. dry unprimed seeds (UPd) (PEG soaking), non dried primed seeds (Pnd) vs dry primed seeds (Pd) (drying after soaking), dry primed seeds (Pd) vs. dry unprimed seeds (UPd) (full osmopriming process), primed seeds imbibed on water (P7h) vs unprimed seeds imbibed on water (UP7h) (germination after osmopriming). Biological replicates: 2 replicates for comparison PEG soaking, drying after soaking, full osmopriming process and germination after osmopriming.

Project description:Intertidal zone organisms can experience transient freezing temperatures during winter low tides, but their extreme cold tolerance mechanisms are not known. Petrolisthes cinctipes is a temperate mid-high intertidal zone crab species that can experience wintertime habitat temperatures below the freezing point of seawater. We examined how cold tolerance changed during the initial phase of thermal acclimation to cold and warm temperatures, as well as the persistence of cold tolerance during long-term thermal acclimation. Thermal acclimation for as little as 6 hours at 8˚C enhanced crab tolerance during a 1h exposure to -2°C relative to crabs acclimated to 18˚C. Potential mechanisms for this enhanced tolerance were elucidated using cDNA microarrays to probe for differences in gene expression in cardiac tissue of warm and cold acclimated crabs during the first day of thermal acclimation. No changes in gene expression were detected until 12h of thermal acclimation. Genes strongly upregulated in warm acclimated crabs represented immune response and extracellular / intercellular processes, suggesting that warm acclimated crabs had a generalized stress response and may have been remodelling tissues or altering intercellular processes. Genes strongly upregulated in cold acclimated crabs included many that are involved in glucose production suggesting that cold acclimation involves increasing intracellular glucose as a cryoprotectant. Structural cytoskeletal proteins were also strongly represented among the genes upregulated in only cold acclimated crabs. There were no consistent changes in composition or the level of unsaturation of membrane phospholipid fatty acids with cold acclimation, which suggests that neither short- nor long-term changes in cold tolerance are mediated by changes in membrane fatty acid composition. Overall, our study demonstrates that initial changes in cold tolerance are likely not regulated by transcriptomic responses, but that gene expression-related changes in homeostasis begin within 12 hours – the length of a tidal cycle. all array data and raw images archived at the Porcelain Crab Array Database (http://array.sfsu.edu)

Crabs were sampled from the 13°C group at 0 h (the start of the experiment) and 24 h, the termination of the experiment. Crabs were sampled from the warm and cold acclimation groups at 6, 12, 18, and 24 hours following the start of thermal acclimation. At each time point, heart tissue from n=16 crabs from each group was dissected, flash frozen and stored at −80°C. A pooled total aRNA sample was prepared for each group by mixing equal quantities of total RNA from n=5 individuals in each group in order to have the same amount of biological diversity within each pooled RNA sample. For microarray hybridizations we used n=25 slides in an incomplete loop design where each sample was hybridized n=5 times, 2-3 times labelled with each Cy dye

Project description:The sfr3-1 mutation causes freezing-sensitivity in Arabidopsis thaliana. The mutated gene has been identified by positional cloning and is currently being characterised. The mutant appears normal when grown in the warm (no phenotype has been identified associated with such growth). However, following cold acclimation and subsequent freezing mutant plants are severely damaged whilst wild type plants are not. This suggests that sfr3 is deficient in the cold acclimation process. Micro-array analysis will enable the identification of any transcriptional changes during the cold acclimation process. This information will then be used, together with information obtained by gene characterisation, in order to more fully understand the nature of the sfr3 mutation.
