| 3 | Mapping aboveground biomass and its prediction uncertainty using LiDAR and field data, accounting for tree-level allometric and LiDAR model errors显示文摘Background: The increasing availability of remotely sensed data has recently challenged the traditional way of performing forest inventories, and induced an interest in model-based inference. Like traditional design-based inference, model-based inference allows for regional estimates of totals and means, but in addition for wall-to-wall mapping of forest characteristics. Recently Light Detection and Ranging(LiDAR)-based maps of forest attributes have been developed in many countries and been well received by users due to their accurate spatial representation of forest resources. However, the correspondence between such mapping and model-based inference is seldom appreciated. In this study we applied hierarchical model-based inference to produce aboveground biomass maps as well as maps of the corresponding prediction uncertainties with the same spatial resolution. Further, an estimator of mean biomass at regional level, and its uncertainty, was developed to demonstrate how mapping and regional level assessment can be combined within the framework of model-based inference.Results: Through a new version of hierarchical model-based estimation, allowing models to be nonlinear, we accounted for uncertainties in both the individual tree-level biomass models and the models linking plot level biomass predictions with LiDAR metrics. In a 5005 km2 large study area in south-central Sweden the predicted aboveground biomass at the level of 18 m×18 m map units was found to range between 9 and 447 Mg·ha^-1. The corresponding root mean square errors ranged between 10 and 162 Mg·ha^-1. For the entire study region, the mean aboveground biomass was 55 Mg·ha^-1 and the corresponding relative root mean square error 8%. At this level 75%of the mean square error was due to the uncertainty associated with tree-level models.Conclusions: Through the proposed method it is possible to link mapping and estimation within the framework of model-based inference. Uncertainties in both tree-level biomass models and models linking plot level biomass with LiDAR data are accounted for, both for the uncertainty maps and the overall estimates. The development of hierarchical model-based inference to handle nonlinear models was an important prerequisite for the study. | Svetlana Saarela AndréWästlund Emma Holmström Alex Appiah Mensah Sören Holm Mats Nilsson Jonas Fridman Göran Ståhl | 2020 | Forest Ecosystems2020,7,3: | 3 |

| 6 | Improved cryopreservation of human hepatocytes using a new xeno free cryoprotectant solution显示文摘AIM:To optimize a xeno-free cryopreservation protocol for primary human hepatocytes.METHODS:The demand for cryopreserved hepatocytes is increasing for both clinical and research purposes.Despite several hepatocyte cryopreservation protocols being available,improvements are urgently needed.We first compared controlled rate freezing to polystyrene box freezing and did not find any significant change between the groups.Using the polystyrene box freezing,we compared two xeno-free freezing solutions for freezing of primary human hepatocytes:a new medium(STEM-CELLBANKER,CB),which contains dimethylsulphoxide(DMSO) and anhydrous dextrose,both permeating and non-permeating cryoprotectants,and the frequently used DMSO-University of Wisconsin(DMSOUW) medium.The viability of the hepatocytes was assessed by the trypan blue exclusion method as well as a calcein-esterase based live-dead assay before and after cryopreservation.The function of the hepatocytes was evaluated before and after cryopreservation by assessing enzymatic activity of 6 major cytochrome P450 isoforms(CYPs):CYP1A2,CYP2C9,CYP2C19,CYP2D6,CYP3A4 and CYP3A7.RESULTS:The new cryoprotectant combination preserved hepatocyte viability significantly better than the standard DMSO-UW protocol(P < 0.01).There was no significant difference in viability estimation between both the trypan blue(TB) and the Live-Dead Assay methods.There was a correlation between viability of fresh hepatocytes and the difference in cell viability between CB and DMSO protocols(r 2 = 0.69) using the TB method.However,due to high within-group variability in the activities of the major CYPs,any statistical between-group differences were precluded.Cryopreservation of human hepatocytes using the cryoprotectant combination was a simple and xeno-free procedure yielding better hepatocyte viability.Thus,it may be a better alternative to the standard DMSO-UW protocol.Estimating CYP activities did not seem to be a relevant way to compare hepatocyte function between different groups due to high normal variability between different liver samples.CONCLUSION:The cryoprotectant combination may be a better alternative to the standard DMSO-UW protocol in primary human hepatocyte cryopreservation. | Mohammed Saliem Frida Holm Rosita Bergstrm Tengzelius Carl Jorns Lisa-Mari Nilsson Bo-Gran Ericzon Ewa Ellis Outi Hovatta | 2012 | World Journal of Hepatology2012,4,5: | 2 |
| 7 | Interferon-γ inhibits ghrelin expression and secretion via a somatostatin-mediated mechanism显示文摘AIM:To investigate if and how the proinflammatory cytokine interferon γ(IFNγ) affects ghrelin expression in mice.METHODS:The plasma concentration of ghrelin,andgastric ghrelin and somatostatin expression,were examined in wild-type mice and mice infected with Helicobacter pylori(H.pylori).Furthermore,ghrelin expression was examined in two achlorhydric mouse models with varying degrees of gastritis due to bacterial overgrowth.To study the effect of IFNγ alone,mice were given a subcutaneous infusion of IFNγ for 7 d.Finally,the influence of IFNγ and somatostatin on the ghrelin promoter was characterized.RESULTS:H.pylori infection was associated with a 50% reduction in ghrelin expression and plasma concentration.Suppression of ghrelin expression was inversely correlated with gastric inflammation in achlorhdyric mouse models.Subcutaneous infusion of IFNγ suppressed fundic ghrelin mRNA expression and plasma ghrelin concentrations.Finally,we showed that the ghrelin promoter operates under the control of somatostatin but not under that of IFNγ.CONCLUSION:Gastric infection and inflammation is associated with increased IFNγ expression and reduced ghrelin expression.IFNγ does not directly control ghrelin expression but inhibits it indirectly via somatostatin. | Jesper AB Strickertsson Kristina BV DΦssing Anna JM Aabakke Hans-Olof Nilsson Thomas VO Hansen Ulrich Knigge Andreas Kjr Torkel Wadstrm Lennart Friis-Hansen | 2011 | World Journal of Gastroenterology2011,17,26: | 2 |
