Brain inflammation may be friend, not foe, for Alzheimer's patients

...zheimer’s disease compared to healthy people. It’s recognized as a critical player in bringing about much of the brain damage that follows a stroke and brain injury, so it’s no surprise that its presence in the brains of Alzheimer’s patients would be assumed to be part of the problem. In the original develop...

The insect vector always bites twice

... of the threat from vector-borne diseases has been recognized and the problem is prompting research scientists to take a strong interest. Most of these infections, classified as emerging or re-emerging diseases, are linked to ecosystem changes, climatic variations or pressure from human activities. Malaria, sle...

A new plant-bacterial symbiotic mechanism promising for crop applications

...prising result calls into question the universally recognized model of molecular communication that initiates the rhizobia-legume symbiosis. This common model requires the presence of several nod genes which allow synthesis of the Nod factor, a compound elaborated by the bacterium which enables the plant to rec...

UI anthropologist, colleagues discover remains of earliest giant panda

...Advancement of Science, Ciochon is internationally recognized for his contributions to the fields of primate paleontology and paleoanthropology in Asia concerning "anthropoid origins" and Homo erectus evolution and dispersal....

Modified mushrooms may yield human drugs

...ew genes into mushrooms. "There has always been a recognized potential of the mushroom as being a choice platform for the mass production of commercially valuable proteins," said Charles Peter Romaine, who holds the John B. Swayne Chair in spawn science and professor of plant pathology at Penn State. "Mushroo...

Mice with a migraine show signs of brain damage

...ury as well as migraine. While it’s been widely recognized that CSD underlies some migraines, Nedergaard’s team linked the phenomenon for the first time to both severe hypoxia and to damage to brain cells. As a result of CSD, the team found changes to the synapses, the connections between brain cells known a...

Molecule that destroys bone also protects it, new research shows

...y at Buffalo has shown. The component, IL-17, was recognized only in the past 18 months to be a primary cause of bone destruction and inflammation in autoimmune diseases. Therapies that target IL-17 or its cellular receptor currently are being developed. However, a UB molecular biologist has discovered that...

Herpes infection may be symbiotic, help beat back some bacteria

...sults hold for human diseases." Scientists have recognized for years that many types of bacteria and other microorganisms live in the human gut to the advantage of both the microbes and their human hosts. The results from the Virgin lab are among the first to suggest the potential for symbiotic benefits from...

Gene thought to assist chemo may help cancer thrive

...pen access journal PLoS ONE. “P53 has long been recognized as a key player in directing chemotherapy-damaged cancer cells to self annihilate, but less attention has been paid to p53’s role in repairing damaged cells,”said John McDonald, chair of Georgia Tech’s School of Biology and chief research scientist a...

Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...s why a study that appeared in the internationally recognized journal, "Science," is considered an important step forward in the understanding of how chloroplasts communicate with a cell’s nucleus when stresses such as drought, heat, salinity or light become too great on the organism. A research team that inc...

Genetic fingerprints identify brain tumors' origins

... that predispose children to PAs. "It should be recognized that the genetic alterations in this tumor may be very subtle," Gutmann notes. "When we looked at gene activity levels in the tumors as a function of brain location, though, a very interesting pattern began to emerge." Cells in different parts of ...

Changes in amino acids in the 1918 influenza virus cut transmission

...irus, and sialic acid, a cellular molecule that is recognized by hemaglutinins of both human and avian strains of influenza virus. These molecules are key to initiation of infection. There are 16 different subtypes of hemagglutinin called H1 through H16, present in influenza virus strains circulating in birds....

Navigable nanotransport

...sule can be easily decorated with species that are recognized by cells, showing the transporter the way to reach its goal, such as a tumor cell. To demonstrate the power of their new concept, Kim and his team chose rigid, disk-shaped monomers equipped with a ring of special molecular "hooks" that can be acti...

New details on how the immune system recognizes influenza

...epitopes--the critical sites on the virus that are recognized by the immune system. The findings, reported by re...influenza virus epitopes in the database are those recognized by a type of immune cell known as a T cell; far fewer are recognized by B cells, a type of white blo...

Metacognition: Faced with a test, rats can check their knowledge first

NIAID DNA vaccine for H5N1 avian influenza enters human trial

...., together with a team of scientists from the VRC recognized the potential for employing new vaccine technology against influenza, a disease for which effective vaccines have long been made, but for which the reliability of supply and manufacturing capacity has been problematic. Dr. Nabel and his colleagues pr...

UTSA researchers examine effects of global warming on Antarctic
