Cell barrier shows why bird flu not so easily spread among humans
Although more than 100 people have been infected with the H5N1 avian influenza virus, mostly from close contact with infected poultry, the fact that the virus does not spread easily from its pioneering human hosts to other humans has been a biomedical puzzle. Now, a study of cells in the human respiratory tract reveals a simple anatomical difference in the cells of the system that makes it...Penn researcher shows that DNA gets kinky easily at the nanoscale
Scientists have answered a long-standing molecular stumper regarding DNA: How can parts of such a rigid molecule bend and coil without requiring large amounts of force? According to a team of researchers from the United States and the Netherlands, led by a physicist from the University of Pennsylvania, DNA is much more flexible than previously believed when examined over extremely small lengths....Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily
PITTSBURGH -- Carnegie Mellon University scientists have made an important discovery that aids the understanding of why HIV enters immune cells with ease. The researchers found that after HIV docks onto a host cell, it dramatically lowers the energy required for a cell membrane to bend, making it easier for the virus to infect immune cells. The finding, in press in Biophysical Journal, will pr...Easily Amplify Genomic DNA with Long-Distance PCR
Long DNA polymerase to genotypemice Cardiovascular Research Center, University of Cincinnati, Cincinnati, OH We developed a simple, reliable procedure to genotype mice usinglong-distance PCR, whereby genomic DNA is isolated from mouse ear clips, an...Printable CELLocate Log Sheets for Easily Locating Adhererent Cells
Log Sheets for Easily Locating Adhererent Cells CELLocate is the ideal solution for relocating adherent cells that have been used for microinjection. These sterile coverslips come with a microgrid pattern. Using the CELLocate proto...Anti-ethanol arguments are easily debunked
- There has been a great deal of media coverage on biofuels and ethanol, much of it confusing. I want to save you the trouble of reading all this confusing information, so let's straighten out all the...Study points out that HIV vaccine may not be accepted easily
Researchers feel that in the next ten years, the HIV vaccine will be ready for use, but there may// be a lot of barriers preventing the acceptance of the vaccine by the people. The research done by University of Toronto researchers said that it is important that the health workers of the world gets the common people ready for accepting the vaccine, which may be quite difficult job to d...Data On Quality Of Health Care Can Be Easily Obtained
Even minimal data derived from a small group of patients can provide an adequate representation of the quality of health care// instituted by private health practitioners and their office practice, according to a new study published in Journal of General Internal Medicine. Highly consistent and reliable data can be provided by a group of 45 patients, according to the present study in...Older Adults Get Distracted More Easily
Filtering out distractions become increasingly difficult for older adults due to brain related changes, according to recent research results. // This task is reasonably easy where younger adults are concerned. The healthy middle aged adults and youngsters in their twenties were equally good where concentrating is concerned, according to functional magnetic resonance imaging (fMRI) studies conduc...Mumps Epidemic Spreads Easily From Infected Air Travelers
Six other Midwestern states, including Illinois seem to be in the grips of a mumps epidemic which initially sparked off in Iowa, and health officials suspect// that it spread easily to the other states, when potentially infected passengers, traveling by air, might have helped spread the infection to the other states. This only goes to show how certain air-borne diseases can spread easi...Caffeine Makes People Persuade Easily
Australian scientists say that caffeine makes us more likely to say ‘yes’ to persuasive arguments. Researchers, found that moderate amount //of stimulants increases people's willingness to be persuaded. About 140 students participated in two experiments about how they viewed voluntary euthanasia and abortion. They were given either straight orange juice or juice laced wi...
