TL;DR: In this paper, the authors construct decadal budgets for methane sources and sinks between 1980 and 2010, using a combination of atmospheric measurements and results from chemical transport models, ecosystem models, climate chemistry models and inventories of anthropogenic emissions.
Journal ArticleDOI

TL;DR: The results indicate that wetland emissions dominated the inter-annual variability of methane sources, whereas fire emissions played a smaller role, except during the 1997–1998 El Niño event.
Journal ArticleDOI

TL;DR: In this article, a global Bayesian variational inversion of CO2 surface fluxes during the period 1988-2008 is presented, where weekly fluxes are estimated on a 3.75 degrees x 2.5 degrees (longitude-latitude) grid throughout the 21 years.
Journal ArticleDOI
Rho GTPases in human breast tumours: expression and mutation analyses and correlation with clinical parameters.
TL;DR: The data show that Rho proteins are overexpressed in breast tumours (2) overexpression is not regulated on the mRNA level (3) the expression level of RhoA-like proteins correlates with malignancy and (4) Rhoprotein expression was neither related to p53 nor to HER-2/neu oncogene status and are not altered by mutation in Breast tumours.
Journal ArticleDOI
A new phospholipase-C-calcium signalling pathway mediated by cyclic AMP and a Rap GTPase.
Martina Schmidt,Sandrine Evellin,Paschal A. Oude Weernink,Frank vom Dorp,Holger Rehmann,Jon W. Lomasney,Karl Jakobs +6 more
TL;DR: A new PLC and calcium signalling pathway that is triggered by cyclic AMP (cAMP) and mediated by a small GTPase of the Rap family is reported, and involve the recently identified PLC-ɛ isoform.
