New Lab Research May Help Those Deafened By Immune System Attack

...ation test known as Western blot, is known to give accurate results only some of the time. The U-M team reported in previous paper in the Journal of Neuroscience that IESCA is identical to a protein called CTL2, or choline transport-like protein 2. In the new study, the researchers tested blood from the 63 p...

3D Atlas Will Help Navigate The Spinal Cord

...research is the rat. There is no comprehensive and accurate atlas of the rat spinal cord; indeed, the problem is greater: there is no comprehensive structural study of the spinal cord of any species, including humans. A new project supported by the Christopher Reeve Paralysis Foundation is designed to redres...

The synapse is a shotgun

...r Terrence Sejnowski, has developed a biologically accurate computer simulation of synaptic function. The simulation combines 3-D electron microscope maps with computer simulation and physiological measurements from real neurons. Their in silico modeling indicates that the synapse may behave more like a shotg...

New imaging technology shown to detect pancreatic inflammation in type 1 diabetes

...d glucose and full-blown diabetes. Today, the only accurate method for detecting the progression or regression of insulitis is a biopsy of the pancreas, which is almost never performed because it is an invasive and potentially risky procedure. "The most exciting aspect of this study is that it demonstrates ...

Researchers identify genes associated with lung transplant rejection

... will lead to an earlier, more sensitive, and more accurate standard test for chronic lung rejection, as well as greater understanding of the rejection process. The study is being published in the September 2005 issue of the Journal of Heart and Lung Transplantation, currently available online. In obliterat...

U-M researchers identify new blood test for prostate cancer

...erhaps the most important function in cells -- the accurate copying of DNA during cell division. New research published this week in Molecular Cell from the laboratory of Rockefeller University's Michael O'Donnell, a Howard Hughes Medical Institute Investigator, now shows that one of these proteins, the beta ...

New tooth enamel dating technique could help identify disaster victims

...as evaluating skeletal remains and tooth wear, are accurate only to within five to 10 years in adults, Buchholz said. The research was reported in this week's edition of the journal Nature. Buchholz said Swedish forensic scientists already have used enamel dating to help narrow the search for victims of las...

NASA satellite data provides rapid analysis of Amazon deforestation

... climate while elevating the need for frequent and accurate assessment of forest loss. In the Brazilian Amazon alone, where the growth of cattle ranching and cropland agriculture are the primary causes of forest clearing, annual clear-cutting and burning of forests cover about 7,700 square miles or about the ...

Elusive salamanders have role in developing new sampling models

...op a method to make field sampling techniques more accurate and efficient. With that information, we can improve our models, and we should be able to do a better job of predicting the type and location of suitable habitats plus minimize unnecessary and time-consuming sampling."

Researchers develop new testing methods for potential monkeypox or smallpox outbreak

...such test, called the ELISA test, resulted in very accurate results (95 percent sensitivity, 90 percent specificity.) This high level of accuracy allowed Slifka and colleagues to correctly diagnose previously confirmed cases as well as confirm several probable,suspect cases of monkeypox that had remained unco...

The Church group's technology is based on converting a widely available and relatively inexpensive microscope with a digital camera for use in a rapid automated se...

A 'dimmer switch' for genes

...w much information the librarian provides, and how accurate that information is, must be tightly controlled. Without the right information, cells can't behave properly, and may, as in the case of cancer, grow out of control. The connection between factors such as Ets-1 and a number of cancers prompted the stu...

California computer scientists double volume of data in NIH biotech repository
