In the first study of vitamin K and Non-Hodgkin lymphoma risk, researchers at the Mayo Clinic campus in Minnesota have found that people who have higher intakes of vitamin K from their diet have a lower risk of developing Non-Hodgkin lymphoma. Non-Hodgkin Lymphoma is a cancer of the immune system and is the most common hematologic malignancy in the United States.At the 101st Annual Meeting of the American Association for Cancer Research (AACR), the researchers report that the risk of...

The natural-occurring biopolymer known as chitosan is being put forward as an effective alternative to growth-promoting antibiotics in the diet of ruminants, according to research carried out by scientists at the Basque technological center, Neiker-Tecnalia. The presence of these antibiotics as additives in the diet of ruminants has been prohibited in the European Union since 2006, given that their use is linked to developing microbial resistance to antibiotics.The main problem arising from...

With the passage of a molecule through the labyrinth of a chemical system being so critical to catalysis and other important chemical processes, computer simulations are frequently used to model potential molecule/labyrinth interactions. In the past, such simulations have been expensive and time-consuming to carry out, but now researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new algorithm that should make future simulations easier and faster to...

Database details 2.7 million possible structures for molecular sievesIn all the world, there are about 200 types of zeolite, a compound of silicon, aluminum and oxygen that gives civilization such things as laundry detergent, kitty litter and gasoline. But thanks to computations by Rice University professor Michael Deem and his colleagues, it appears there are -- or could be -- more types of zeolites than once thought.A lot more.A project that goes back 20 years came to fruition earlier this...

Thin-film zeolite membranes with tiny, molecule-sized pores are one step closer to replacing the energy-intensive processes now used in industrial separations, a group of academic researchers is reporting.Writing this week in Science magazine, the group says the membranes' ability to separate molecules in a mixture is significantly improved by subjecting the zeolite to rapid thermal processing (RTP). By heating the membranes from room temperature to 700 degrees Centigrade in one minute,...

Engineers have developed a new method for creating high-performance membranes from crystal sieves called zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates.The ability to separate and purify specific molecules in a chemical mixture is essential to chemical manufacturing. Many industrial separations rely on distillation, a process that is easy to design and implement but consumes a lot...

Now researchers at the University of Washington are using the same principle for biomedical applications. Mixing chitosan, found in the shells of crabs and shrimp, with an industrial polyester creates a promising new material for the tiny tubes that support repair of a severed nerve, and could serve other medical uses. The hybrid fiber combines the biologically favorable qualities of the natural material with the mechanical strength of the synthetic polymer."A nerve guide requires very...

Scratches on an otherwise perfect looking vehicle can be a real annoyance for car owners, but scientists have developed a polyurethane coating that heals its own scratches when exposed to sunlight."We developed a polymeric material that is able to repair itself by exposure to the sun," said Marek Urban of the University of Southern Mississippi in Hattiesburg. The findings are published in the journal Science.The report says the self-healing coating uses chitosan. It's a substance...

A research project at Rice University has brought scientists to the brink of comprehending a long-standing medical mystery that may link cardiovascular disease, osteoporosis and perhaps even Alzheimer's disease. And for that, we can thank the rat.The recent paper in Artery Research by Rice evolutionary biologist Michael Kohn and his team reports they have found that common rats with a genetic mutation have developed a resistance to rat poison, aka warfarin. That's good news for the rats,...
