Preservation technique for marginal livers prevents biliary stricture

Preservation technique for marginal livers prevents biliary stricture

New research shows that a preservation technique known as sequential subnormothermic ex vivo liver perfusion (SNEVLP) prevents ischemic type biliary stricture following liver transplantation using grafts from donations after cardiac death (DCD). Findings published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, indicate that the preservation of DCD grafts using SNEVLP versus cold storage reduces bile duct and endothelial cell injury post transplantation.

Could I squeeze by you?

Scientists at the U.S. Department of Energy's Ames Laboratory have developed deeper understanding of the ideal design for mesoporous nanoparticles used in catalytic reactions, such as hydrocarbon conversion to biofuels. The research will help determine the optimal diameter of channels within the nanoparticles to maximize catalytic output.

Perceived hatred fuels conflicts between Democrats and Republicans, Israelis and Palestinians

Perceived hatred fuels conflicts between Democrats and Republicans, Israelis and Palestinians

What makes human conflict intractable – and how can psychological research resolve historic disagreements? A new study published in the Proceedings of the National Academy of Sciences by a team of researchers from The New School for Social Research, Northwestern University and Boston College demonstrates how seemingly unsolvable political and ethnic conflicts are fueled by asymmetrical perceptions of opponents' motivations – and that these tensions can be relieved by providing financial incentives to better understand what drives an adversary group.

Resetting the circadian clock: Shift workers might want to skip high-iron foods

(SALT LAKE CITY)—Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don't disrupt the circadian clock in their livers.

Disrupted circadian clocks, researchers believe, are the reason that shift workers experience higher incidences of type 2 diabetes, obesity and cancer. The body's primary circadian clock, which regulates sleep and eating, is in the brain. But other body tissues also have circadian clocks, including the liver, which regulates blood glucose levels.

UNH scientist: Cosmic rays threaten future deep-space astronaut missions

DURHAM, N.H. –- Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky, concludes a new paper by University of New Hampshire scientists.

UNH research highlights extent and effects of school violence

DURHAM, N.H. – Six percent of U.S. children and youth missed a day of school over the course of a year because they were the victim of violence or abuse at school. This was a major finding of a study on school safety by University of New Hampshire researchers published this month in the Journal of School Violence.

Color and texture matter most when it comes to tomatoes

CHICAGO –A new study in the Journal of Food Science, published by the Institute of Food Technologists (IFT), evaluated consumers' choice in fresh tomato selection and revealed which characteristics make the red fruit most appealing.

The researchers found that the most important fresh tomato attributes were color, amount of juice when sliced and size. Consumers were most drawn to fresh tomatoes shown to be red, firm, medium/small sized, crisp, meaty, and that contain few seeds.

Kung fu stegosaur

Boulder, CO, USA — Stegosaurs might be portrayed as lumbering plant eaters, but they were lethal fighters when necessary, according to paleontologists who have uncovered new evidence of a casualty of stegosaurian combat. The evidence is a fatal stab wound in the pubis bone of a predatory allosaur. The wound – in the conical shape of a stegosaur tail spike – would have required great dexterity to inflict and shows clear signs of having cut short the allosaur's life.
