Quaternary paleoclimatology, neotropical biodiversity, and potential effects of global warming.

open access: yesContributions to Science, 2007
[CAT] Els canvis climàtics quaternaris enregistrats a l’hemisferi nord també han afectat la regió neotropical i han contribuït a definirne els patrons actuals de biodiversitat. Els estudis moleculars de DNA que s’han dut a terme en espècies neotropicals actuals mostren una acceleració significativa de les taxes d’especiació en els darrers 5 milions d ...

Tumor‐stromal crosstalk and macrophage enrichment are associated with chemotherapy response in bladder cancer

open access: yesFEBS Open Bio, EarlyView.
Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

open access: yesFEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Impacts of hydrogen on tropospheric ozone and methane and their modulation by atmospheric NOx

open access: yesFrontiers in Energy Research
Atmospheric hydrogen concentrations have been increasing in recent decades. Hydrogen is radiatively inert, but it is chemically reactive and exerts an indirect radiative forcing through chemistry that perturbs the concentrations of key species within the

Ice sheets as a significant source of highly reactive nanoparticulate iron to the oceans [PDF]

open access: yes, 2014
The Greenland and Antarctic Ice Sheets cover ~\n10% of global land surface, but are rarely considered as active components of the global iron cycle. The ocean waters around both ice sheets harbour highly productive coastal ecosystems, many of which are ...

Meta‐analysis fails to show any correlation between protein abundance and ubiquitination changes

open access: yesFEBS Open Bio, EarlyView.
We analyzed over 50 published proteomics datasets to explore the relationship between protein levels and ubiquitination changes across multiple experimental conditions and biological systems. Although ubiquitination is often associated with protein degradation, our analysis shows that changes in ubiquitination do not globally correlate with changes in ...

Effect of management system and dietary seasonal variability on environmental efficiency and human net food supply of mountain dairy farming systems

open access: yesJournal of Dairy Science
: Mountain dairy cattle farming systems are pivotal for the economy, as well as for social and environmental aspects. They significantly contribute to rural development, which is currently strongly prioritized in the common European Union agricultural ...

Metrics for Aggregating the Climate Effect of Different Emissions: A Unifying Framework. ESRI WP257, September 2008 [PDF]

open access: yes, 2008
Multi-gas approaches to climate change policies require a metric establishing “equivalences” among emissions of various species. Climate scientists and economists have proposed four classes of such metrics and debated their relative merits.

Factors controlling Hadley circulation changes from the Last Glacial Maximum to the end of the 21st century [PDF]

open access: yes, 2017
The Hadley circulation (HC) extent and strength are analyzed in a wide range of simulated climates from the Last Glacial Maximum to global warming scenarios.
