Permafrost and Periglacial Processes

The microbial process of methane (CH4) production during the back-freezing of permafrost soils in autumn and the future fate of produced CH4 in the thawing phase of the following spring are not well understood. Long-term CH4 flux studies in the Lena Delta (Siberia) indicate that back-stored CH4 adds to the emission of newly-produced CH4 at the beginning of the vegetation period. Further field a...

Permafrost and Periglacial Processes

Sphagnum (spp.) is widely distributed in permafrost regions around the arctic and subarctic. The moisture content of the moss layer affects the thermal insulative capacity and preservation of permafrost. It also controls the growth and collapse history of palsas and other peat mounds, and is relevant, in general terms, to permafrost thaw (therrnokarst). In this study, we test and calibrate seve...

Metabolism: A New Frontier in Cancer Research

This is validated by the approval of Agas and Celgene’s enasidenib by the FDA. This drug modulates the metabolism and is used as a medication against acute myelogenous leukemia. Enasidenib is an inhibitor of the mutated isocitrate dehydrogenase (IDH2), one of the main enzymes of the citric acid cycle (also known as Krebs cycle), a central pathway which converts molecules coming from all 3 main ...
