Drought down-regulates above- and belowground carbon fluxes, however, the resilience of trees to drought will also depend on the speed and magnitude of recovery of these above- and belowground fluxes after re-wetting. Carbon isotope composition of above- and belowground carbon fluxes at natural abundance provides a methodological approach to study the coupling between photosynthesis and soil respiration (SR) under conditions (such as drought) that influence photosynthetic carbon isotope discrimination. In turn, the direct supply of root respiration with recent photoassimilates will impact on the carbon isotope composition of soil-respired CO2...

CO2 laser has a beneficial effect on stem cells by mechanisms that are not clearly elucidated. We hypothesize that the effect of fractional CO2 laser on human adipose-derived stem cells (ADSC) could be due to changes in redox homeostasis and secretion of factors contributing to cellular proliferation and angiogenic potential. ADSC incubated in medium containing 0.5 or 10 % FBS were exposed to a single irradiation of a 10,600-nm fractional CO2 laser; non-irradiated ADSC were used as control. Viability/proliferation of ADSC was assessed by MTT assay; the intracellular reactive oxygen species (ROS) levels and the mitochondrial membrane potential (∆Ψm) were determined with DCFH-DA and JC-1 fluorescent probes, respectively...
