Oleoyl-lysophosphatidylcholine limits endothelial nitric oxide bioavailability by induction of reactive oxygen species.

PLoS ONE, 2014
Previously we reported modulation of endothelial prostacyclin and interleukin-8 production, cyclooxygenase-2 expression and vasorelaxation by oleoyl- lysophosphatidylcholine (LPC 18:1).

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

Classification of EEG-P300 Signals Extracted from Brain Activities in BCI Systems Using ν-SVM and BLDA Algorithms [PDF]

Applied Medical Informatics, 2014
In this paper, a linear predictive coding (LPC) model is used to improve classification accuracy, convergent speed to maximum accuracy, and maximum bitrates in brain computer interface (BCI) system based on extracting EEG-P300 signals.

Lysophosphatidylcholine as a death effector in the lipoapoptosis of hepatocytess⃞

Journal of Lipid Research, 2008
The pathogenesis of nonalcoholic steatohepatitis (NASH) is unclear, despite epidemiological data implicating FFAs. We studied the pathogenesis of NASH using lipoapoptosis models. Palmitic acid (PA) induced classical apoptosis of hepatocytes.

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Distinct Plasma LPC Signatures Differentiate COVID-19 Sepsis from Other Sepsis Aetiologies

Biomedicines
Background/Objectives: Low levels of lysophosphatidylcholine (LPC) in the blood can be used as a diagnostic marker for sepsis. SARS-CoV-2 infection, a more recent cause of sepsis, shares similarities with non-SARS-CoV-2 sepsis but also exhibits distinct ...

Optimizing Prolonged (6 h) Normothermic Machine Perfusion of Donor Kidneys (PROPER Study)

Artificial Organs, EarlyView.
Prolonged ex situ normothermic machine perfusion of donor kidneys up to 6 h is feasible, maintaining viability and histological integrity. Key protocol optimizations include fresh red blood cells, albumin supplementation, and urine recirculation—laying the groundwork for assessment and potential pretransplant interventions in future clinical trials ...

The effect of lysolecithin on prostanoid and platelet-activating factor formation by human gall-bladder mucosal cells

Mediators of Inflammation, 1995
It has been demonstrated that lysolecithin (lysophosphatidyl choline, LPC) produces experimental cholecystitis in cats mediated by arachidonic acid metabolites. LPC is a cytolytic agent that has been postulated as a contributing factor in the development

Do tax havens affect the usage of share buybacks schemes?

Annals of Public and Cooperative Economics, EarlyView.
Abstract This study examines whether the use of tax haven subsidiaries by U.S. multinational corporations (MNCs) is associated with more intense usage of share buybacks. I find that MNCs' more intensive tax haven subsidiary usage is positively associated with a higher buyback ratio, a higher level of free cash flow and a higher level of return on ...

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

Archaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.
