Nano-paper Filter Removes Virus Particles
2014-04-01 16:31:23

Uppsala University Nanotechnology and Functional Materials, Uppsala University have developed a paper filter, which can remove virus particles with the efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofibers, directly derived from nature. The research was carried out in collaboration with virologists from the Swedish University of Agricultural Sciences/Swedish National Veterinary Institute and is published...

New Gel Promotes Bone Growth On Implants Used In Surgical Procedures
2014-03-31 14:11:46

Uppsala University A research group at Uppsala University, Sweden has developed a new responsive coating for implants used in surgery to improve their integration into bone and to prevent rejection. Neutron scattering experiments at the Institut Laue-Langevin (ILL) in Grenoble, France have shown how a protein that promotes bone growth binds to this surface and can be released in a controlled way. Orthopedic and dental implants must last for many years. Success for these surgical...

New research from Uppsala University shows that saturated fat builds more fat and less muscle than polyunsaturated fat. This is the first study on humans to show that the fat composition of food not only influences cholesterol levels in the blood and the risk of cardiovascular disease but also determines where the fat will be stored in the body. The findings have recently been published in the American journal Diabetes. The study involved 39 young adult men and women of normal weight, who...

New Method Allows Researchers To Sort Out DNA Contamination
2014-01-28 06:53:19

April Flowers for redOrbit.com - Your Universe Online Special precautions are usually a part of retrieving ancient DNA to prevent DNA from researchers or the environment from mixing with that of the fossil. Many ancient fossils, however, have been lying forgotten in museum collections for decades that have become contaminated with present-day human DNA before even entering the laboratory. A solution for this problem, published in Proceedings of the National Academy of Sciences (PNAS),...

Do Mitochondrial Genes Matter?
2014-01-14 11:45:32

Uppsala University Contrary to common belief, mitochondrial genes seem to matter for how well individuals survive and reproduce. These new results are reported by researchers at Uppsala University, Sweden, who studied the genes of a common beetle species. Mitochondria are vital power plants of cells. They carry their own genes, which are inherited only through females, and these genes vary greatly between individuals. In the latest issue of the prestigious scientific journal Ecology...

Bone cancer in dogs is affected by a variety of genetic risk factors. Researchers from Uppsala University, Sweden, and the Broad Institute show this in a new study published in Genome Biology. Osteosarcoma, a type of bone cancer, is a rare but very aggressive form of cancer that primarily affects teenagers. Among some large-sized dog breeds the disease is much more common, but otherwise osteosarcoma in humans and dogs is very similar. In the current study, the researchers compared the...

Seeds from Moringa oleifera trees can be used to purify water. Uppsala University leads a research group which has discovered that seed material can give a more efficient purification process than conventional synthetic materials in use today. Clean water is essential for good health. In many countries it is still difficult to obtain clean water. Even developed countries can benefit from a process that treats waste water without addition of further synthetic chemicals. In a project lead...

Retroviruses are important pathogens capable of crossing species barriers to infect new hosts, but knowledge of their evolutionary history is limited. By mapping endogenous retroviruses (ERVs), retroviruses whose genes have become part of the host organism's genome, researchers at Uppsala University, Sweden, can now provide unique insights into the evolutionary relationships of retroviruses and their host species. The findings will be published in a coming issue of Proceedings of the National...

Pain Processes In Tennis Elbow illuminated Using PET Scanning
2013-10-28 12:06:59

Uppsala University Physiological processes in soft tissue pain such as chronic tennis elbow can be explored using diagnostic imaging methods. This is demonstrated by researchers from Uppsala University and the results are now being published in the prestigious journal PLOS ONE. The pain physician and researcher Magnus Peterson is presenting a new use of positron emission tomography (PET) and a tracer for the signal receptor NK1 for visualizing a physiological process associated with pain....

April Flowers for redOrbit.com - Your Universe Online A new study from Uppsala University and the European Society of Cardiology (ESC) shows that mechanical chest compressions are as equally effective as manual CPR. The LINC study, published in the journal Resuscitation, included 2,589 patients from six European sites who had suffered an out-of-hospital cardiac arrest and needed resuscitation. "The study was designed to show a better 4-hour survival in the group treated with mechanical...
