Several studies indicate a significant effect of PEMFT in patients with chronic medical conditions. OBJECTIVE: The aim of this study was to evaluate the influence of PEMFT on skin microcirculation in healthy volunteers. METHODS: 15 healthy participants were included. Nine PEMF treatments were applied over three weeks in an 48-hour interval. The PEMFT system (BEMER) was placed beneath one of the participants' leg with the contralateral side serving as a control. A forty-minute application period was preceded by a 10-minute resting phase. Measuring was done using two Laser Doppler probes (LEA) placed on each anterior lateral thigh. RESULTS: All outcome parameters including flow, mixed venous oxygen saturation and relative venous hemoglobin showed a significant increase during the experiment when compared to the baseline values of the resting phase in both groups (p < 0.01). Comparing both groups, the measurement values during the experiment did not differ (p > 0.05) except for higher flow values in the control group (P = 0.03). Over time, baseline values of both groups showed no significant difference (p > 0.05). CONCLUSION: We found a significant increase of all measurement parameters during the study compared to the baseline values with no difference between the PEMF and control group.}, language = {en} } @misc{DoebbelingHildebrandtMierschKhannaetal., author = {D{\"o}bbeling-Hildebrandt, Niklas and Miersch, Klaas and Khanna, Tarun M. and Bachelet, Marion and Bruns, Stephan B. and Callaghan, Max and Edenhofer, Ottmar and Flachsland, Christian and Forster, Piers M. and Kalkuhl, Matthias and Koch, Nicolas and Lamb, William F. and Ohlendorf, Nils and Steckel, Jan Christoph and Minx, Jan C.}, title = {Systematic review and meta-analysis of ex-post evaluations on the effectiveness of carbon pricing}, series = {Nature communications}, volume = {15}, journal = {Nature communications}, number = {1}, publisher = {Nature Publishing Group UK}, address = {London}, issn = {2041-1723}, doi = {10.1038/s41467-024-48512-w}, pages = {1 -- 12}, abstract = {Today, more than 70 carbon pricing schemes have been implemented around the globe, but their contributions to emissions reductions remains a subject of heated debate in science and policy. Here we assess the effectiveness of carbon pricing in reducing emissions using a rigorous, machine-learning assisted systematic review and meta-analysis. Based on 483 effect sizes extracted from 80 causal ex-post evaluations across 21 carbon pricing schemes, we find that introducing a carbon price has yielded immediate and substantial emission reductions for at least 17 of these policies, despite the low level of prices in most instances. Statistically significant emissions reductions range between -5\% to -21\% across the schemes (-4\% to -15\% after correcting for publication bias). Our study highlights critical evidence gaps with regard to dozens of unevaluated carbon pricing schemes and the price elasticity of emissions reductions. More rigorous synthesis of carbon pricing and other climate policies is required across a range of outcomes to advance our understanding of "what works" and accelerate learning on climate solutions in science and policy.}, language = {en} }
