...ons," said Quon. PET and CT are standard imaging tools that can be used to pinpoint the location of cance... validation studies will be conducted and software tools need additional development, said Quon, who indicated that the technique might be expanded to includ...

Neural stem cell gene plays crucial role in eye development

...tion of this work, but we finally have the genetic tools to actually test our hypothesis." Other authors that contributed to the study are members of the UNC Neuroscience Center and department of genetics: Dr. Olena Taranova, a former UNC graduate student in neurobiology, now a postdoctoral scientist in...

Making a face: A new and earlier marker of neural crest development

... Based on work from the 1940's before molecular tools were available, the neural crest was thought to form by interactions between neural and non-neural cell layers. "We show in this work that neural crest stem cell precursors are designated very early in development -- as early as the gastrula stages -...

Prozac's target revealed

...e researchers are currently using the approach and tools they've developed to explore whether other treatments for depression--including other drugs and deep brain stimulation--act in the same way as Prozac or in different ways. In addition, the scientists are screening for new drugs that expand the produc...

Mice learn tasks that may help treat human psychiatric disorders

...e deficits in human mental dysfunction or with the tools we use to study the mechanisms that underlie disorders in people." Garner and his colleagues designed a task to measure a process called set shifting in which a focus on one object must be abandoned in favor of another object or task. This test lon...

MRSA vaccine shows promise in mouse study

...fections. "This microbe's ability to acquire the tools it needs to protect itself from the drugs we use to treat it is legendary," said study director Olaf Schneewind, M.D., Ph.D., professor and chairman of microbiology at the University of Chicago, "which is why a vaccine has become such a high priority...

With record resolution and sensitivity, tool images how life organizes in a cell membrane

...what's been missing. We just don't have analytical tools that give us this combination of sensitivity, analytical information and spatial resolution.'' For the Science study, Boxer and colleagues made a spherical lipid vesicle to model a cell membrane, placed it on a small silicon wafer to make the lipid ...

UGA scientists engineer root-knot nematode resistance

... directed primarily at understanding the molecular tools the nematode uses to infect plants. This is a prerequisite for bioengineering durable resistance to these nematodes in crop plants. Through this research, they've discovered the parasitism genes that make a nematode a plant parasite so it can attack...
