Understanding biases in epidemic models important when making public health predictions

...predicting the spread of new, highly transmissible diseases could be important to public health workers, said Wearing. Underestimating the transmissibility of an infection could lead to predicting inadequate levels of disease management, such as contact tracing and quarantining of those exposed. However, Wear...

Biologists determine genetic blueprint of social amoeba

...ining a new and efficient way to study those human diseases with a simple organism in their laboratories. For evolutionary biologists, the genetic blueprint of Dictyostelium, the first amoeba genome to be sequenced, has clarified the place that Dictyostelium occupies in the hierarchy of life. "It is more cl...

Inhaling large amounts of salt can cause hypertension

Underestimating the transmissibility of an infection could lead to predicting inadequate levels of disease management, such as contact tracing and quarantining of those exposed. However, Wear...

New insight into autoimmune disease: Bacterial infections promote recognition of self-glycolipids

...recognition that may contribute to some autoimmune diseases such as multiple sclerosis (MS) and Guillain-Barre...vidence that the development of certain autoimmune diseases may be associated with a bacterial or viral infection that stimulates production of antibodies and i...

Field of beams - Novel system uses polarized light pulses to reveal crop health

Purdue scientists may have found key to halting spinal cord damage

... such as Parkinson's, Huntington's and Alzheimer's diseases - all of which progress slowly and resist treatmen...onditions could be used to treat neurodegenerative diseases as well. "Hypertension drugs, which bind to acrolein and detoxify it, are already under study for t...

Genomic sequences processed in minutes, rather than weeks

...s sequences are analyzed they can provide clues to diseases and possible treatments. Using ScalaBLAST, researchers can manage the large influx of data resulting from new questions that arise during human genome research. Prior to this new tool, it took researchers 10 days to analyze one organism. Now, resear...

A protein in the eye may prevent immune response and protect eyes from disease

...p in the development of therapies for blinding eye diseases such as macular degeneration and autoimmune diseases that occur when the immune system goes awry," says Joan Stein-Sreilein, PhD, senior author of the st...

Decisions, decisions: Male or female?

...n communication via the JAK/STAT pathway misfires, diseases such as cancer can result, he said. "Evolutionarily, germ cells are one of the most ancient cell types, needed by every type of animal to reproduce," Van Doren said. "Their developmental program is very similar, whether we are talking fruit flies or...

Using computers and DNA to count bacteria

Scientists discover that three molecules may be developed into new Alzheimer's drugs

...ol it, said Kosik. The same is true for many other diseases –?from AIDS to cancer. "It is likely that we will need to strategically target different aspects of the disease and put them together." Kosik and his team chose to focus on the neurofibrillary tangles of neurons in the brain that, along with senile ...

Scientists at Galileo Pharmaceuticals confirm inflammatory response linked to glucose levels

New complete muscle grown in the lab

...uild up muscle that has weakened or wasted away in diseases like AIDS. Until now, most scientists have not attempted to provide engineered tissue with its own blood supply. Instead, they have implanted the new tissue into the body and waited for the body itself to infiltrate the tissue with blood vessels. "...

Researchers seek to discover what really happens when a virus enters the body

...es to treatment will allow more intensive study of diseases at the cellular level. A greater understanding of the physiology of an illness will lead to more targeted treatments. ...

Improving the potential of cancer vaccines

... immune response. If they are depleted, autoimmune diseases will result because the immune system is unchecked and goes on to attack the body's own tissues. His group previously reported the existence of tumor-specific Treg cells at tumor sites. "Thus, the tumor cells use these Treg cells to protect themselv...

Researchers feed tiny pills of RNA to planarians to identify genes essential for regeneration

...may be able to use planarians to learn about human diseases that can't be studied in other animal models. Another 35 of the silenced genes may shed light on the parasitic platyhelminthes, such as Schitosoma mansoni, which cause disease in millions of people. The genes identified by the U researchers may be r...

TGen awarded $7.1 million to accelerate brain disease research

The consortium worked with 5 AM solutions, a software development company in Phoenix, to create a central database for data ...

New protein vital for immune response is found in surprise location

...w therapies aimed at preventing and treating viral diseases such as the flu, hepatitis, West Nile virus and SARS. The study is available online and will appear in the Sept. 9 issue of the journal Cell. Working with cultured cells, researchers found that the protein, made by a gene they discovered and named M...
