Estimation of atmospheric nutrient inputs to the Atlantic Ocean from 50 degrees North to 50 degrees South based on large-scale field sampling: Fixed nitrogen and dry deposition of phosphorus [PDF]

, 2010
Atmospheric nitrogen inputs to the ocean are estimated to have increased by up to a factor of three as a result of increased anthropogenic emissions over the last 150 years, with further increases expected in the short- to mid-term at least.

Trends in the chemistry of atmospheric deposition and surface waters in the Lake Maggiore catchment [PDF]

Hydrology and Earth System Sciences, 2001
The Lake Maggiore catchment is the area of Italy most affected by acid deposition. Trend analysis was performed on long-term (15-30 years) series of chemical analyses of atmospheric deposition, four small rivers draining forested catchments and four high

New Insights Into Multi‐Component Atmospheric Wet Deposition Across China: A Multidimensional Analysis

Earth's Future, 2022
Atmospheric wet deposition has attracted much attention because of its removal function of aerosol particles and impact on ecosystem. It is a complex multi‐component process due to various pollutants emission sources and reaction processes.

Atmospheric deposition of phosphorus to land and freshwater [PDF]

Environ. Sci.: Processes Impacts, 2014
Newly-obtained and published data on phosphorus deposition were evaluated to make a global budget, assess bioavailability and spatial and temporal variation, and consider which ecosystems might depend upon atmospheric inputs.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Global modelling of H₂ mixing ratios and isotopic compositions with the TM5 model [PDF]

, 2011
The isotopic composition of molecular hydrogen (H2) contains independent information for constraining the global H2 budget. To explore this, we have implemented hydrogen sources and sinks, including their stable isotopic composition and isotope ...
