Project description:This article describes a suite of global climate model output files that provide continental climatic conditions (monthly temperatures, precipitation, evaporation, precipitation minus evaporation balance, runoff) together with the calculated Köppen-Geiger climate classes and topography, for 28 evenly spaced time slices through the Phanerozoic (Cambrian to Quaternary, 540 Ma to 0 Ma). Climatic variables were simulated with the Fast Ocean Atmosphere Model (FOAM), using a recent set of open-access continental reconstructions with paleotopography and recent atmospheric CO2 and solar luminosity estimates. FOAM is a general circulation model frequently used in paleoclimate studies, especially in the Palaeozoic. Köppen-Geiger climate classes were calculated based on simulated temperature and precipitation fields using Wong Hearing et al.'s [1] implementation of Peel et al.'s [2] updated classification. This dataset provides a unique window onto changing continental climate throughout the Phanerozoic that accounts for the simultaneous evolution of paleogeography (continental configuration and topography), atmospheric composition and greenhouse gas forcing, and solar luminosity.
Project description:We present new global maps of the Köppen-Geiger climate classification at an unprecedented 1-km resolution for the present-day (1980-2016) and for projected future conditions (2071-2100) under climate change. The present-day map is derived from an ensemble of four high-resolution, topographically-corrected climatic maps. The future map is derived from an ensemble of 32 climate model projections (scenario RCP8.5), by superimposing the projected climate change anomaly on the baseline high-resolution climatic maps. For both time periods we calculate confidence levels from the ensemble spread, providing valuable indications of the reliability of the classifications. The new maps exhibit a higher classification accuracy and substantially more detail than previous maps, particularly in regions with sharp spatial or elevation gradients. We anticipate the new maps will be useful for numerous applications, including species and vegetation distribution modeling. The new maps including the associated confidence maps are freely available via www.gloh2o.org/koppen.
Project description:Expression levels of proteins and phosphoproteins, covering major cancer signaling pathways with a special focus on breast cancer biology, were obtained for a series of 109 breast cancer tumor specimens with positive estrogen receptor status. Tumor specimens from patients diagnosed with primary invasive breast carcinoma were collected at the time of surgery between 2008 and 2010 at the Department of Gynecology and Obstetrics / National Center for Tumor Diseases Heidelberg. None of the patients had received neoadjuvant therapy. Institutional Review Board approval was received as ethics vote no. S039/2008 and informed consent was obtained from all patients. Tumor specimens were processed within 20 min after surgery. Samples were stored snap frozen at -80M-BM-0C until further use. Only tumor samples with > 70% tumour cells and positive estrogen receptor status (immunoreactive score M-bM-^IM-% 3) as assessed by routine immunohistochemistry were selected for this study (n = 109). Tumor lysates were printed on a series of nitrocellulose coated glass slides and probed with 128 different primary antibodies directed against proteins and phosphoproteins of interest. Primary antibodies were selected to recognize proteins involved in major cancer signaling pathways with a special focus on breast cancer biology.
