Achilles heel of the herpes virus possibly found

...ppears to function as one "lock" that HSV opens to allow it to enter human cells. They've also found the ge...o get pig cells to express the human B5 protein to allow the pig cells to be infected with human herpes virus. For these studies, Fuller credits the persist...

Study shows humans have ability to track odors, much like bloodhounds

...ith the subjects' heads inside a functional MRI to allow the scientists to see which areas of the brain were most active during sniffing and attempts to identify and localize odors. They found that the left and right nostrils have separate areas of the primary olfactory cortex - the brain's smell center - ...

Anthrax test, developed by army and CDC, receives FDA approval

...ventually follow a similar pathway for approval to allow clinical diagnosticians to use these tests to positively identify pathogens," said Colonel George W. Korch, Jr., commander of USAMRIID. "Successes such as these demonstrate that we can translate our research efforts into products for our health care ...

Researcher gets NSF grant to create mutant maize lines

...ations in maize (corn). The project not only will allow researchers to study the effects of knocking out the function of single genes, one at a time, but also will create seeds for each mutation, or disrupted gene. The seeds will be made widely available to researchers. The new maize lines could one day ...

Scripps research scientists solve structure of a critical innate immune system protein

...en the way to a great many other studies that will allow us to understand exactly how signaling occurs." Significantly, says Wilson, the structure is also another milestone of sorts. These membrane-spanning proteins are rich in repeats that contain a high percentage of the amino acid leucine. This fact wa...

'Mad cow' proteins successfully detected in blood

Understanding biases in epidemic models important when making public health predictions

...lying characteristics of an infection and they can allow the comparison of alternative control measures. Often, however, such models make implicit assumptions that may systematically bias their predictions, say researchers at the University of Georgia. In a paper published today in the online open-access ...

Self-assembled DNA buckyballs for drug delivery

...ll is hollow, and the open spaces in the structure allow water to enter. Dan Luo, Cornell assistant professor of biological and environmental engineering in whose lab the DNA structures were made, suggests that drugs could be encapsulated in buckyballs to be carried into cells, where natural enzymes would ...

International Team Determines Geographic Origin of Leprosy

...f the genetic makeup of the leprosy bacterium will allow clinicians to characterize at a molecular level the M. leprae strain infecting a leprosy patient, which will show whether the patient has a new infection or if the previous infection was incompletely treated and has returned. This, in turn, will aid ...

Inhaling large amounts of salt can cause hypertension

Virginia Tech group adds tools to DNA-targeted anti-cancer drugs

...The UV light does not activate the system but will allow us to see such things as how the assembly enters cells and how much of the drug reaches the DNA," Brewer said. "It is a common practice in the medical field to use luminescent dyes to study cells, so pathology labs will have the equipment needed to m...

Malaria killing a million a year

...as been using since 2001. "Current methods do not allow for a more precise estimate, given that malaria is most often not diagnosed with certainty, as well as the scarcity of reliable data from the communities where it occurs," WHO and UNICEF say. The Millennium Development Goals (MDGs), a set of targets...

Purdue scientists may have found key to halting spinal cord damage

...id. "We are hopeful that detoxifying acrolein will allow doctors to stop the chemical attack cycle as well, adding to the number of treatment methods available." The center was established in 1987 both to develop and to test promising methods of treatment for spinal cord injuries. The center uses its clos...

Genomic sequences processed in minutes, rather than weeks

... understanding the pieces of genome sequences will allow researchers to understand the body's cellular machinery and discover clues to some types of cancer. And it will help in developing drugs or detection methods to be used for particular diseases," said T.P. Straatsma, a PNNL senior research scientist. ...

New tool reveals secrets of migrating cells

... to their final destination." The technique could allow researchers in many fields of biology to track migrating cells, which biologists have discovered are common in many types of tissue, ranging from nerves to lymph nodes. To date, such long-range migrations have been inferred from observations of chemi...

Environmental chemical cocktail may sabotage sperm

...he sperm has lost special "docking" molecules that allow it to bind to the egg. Prof Fraser said: "Human sperm proved to be even more responsive than mouse sperm to genistein. These compounds are classified as environmental oestrogens, but they are very weak, so normally you would expect them to have to b...

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

...applied engineering technologies 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. ...

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

...the reasons for doing this research is that it may allow us to investigate the very earliest processes of how a human gamete and gonad (ovary and testis) develops. Many scientists believe that environmental chemical pollutants that mimic the action of hormones (so called endocrine disrupting chemicals) mig...
