Nicotine rush hinges on sugar in neurons

...ng function – are entirely hydrophobic, Chen said, supporting the theory that the buried water molecule plays a functional role. Chen called the group’s Nature Neuroscience study “one of the few times that you felt that you connected the dots.” The study also represents a tour de force of protein crystallog...

Cells re-energize to come back from the brink of death

... counteract CICD. GAPDH appears to prevent CICD by supporting the functioning of the mitochondria and triggering the activity of certain genes that prevent or repair cell damage. The findings also suggest that the increase in GAPDH provides energy to increase autophagy—the process by which a cell “chews up” deb...

Pregnant mom's exposure to flu vaccine kick-starts fetal immune system

... following maternal vaccination against influenza, supporting the theory that the human neonatal immune system is not deficient or incompetent but, rather, capable of responding to environmental exposures. These conclusions have important implications for determining when immune responses to environmental expos...

Research team identifies new Alzheimer's gene

...use these data to see if there is genetic evidence supporting their idea. Reviewing these data in an hour will permit them to save months of work and thousands of dollars to achieve the same result. Moreover, it paves the way for even more advanced studies using larger sample populations, more powerful array c...

Massive herds of animals found to still exist in Southern Sudan

New study examines 'brain's own marijuana'

...nt from the National Institute of Mental Health is supporting this investigation. “It is widely accepted that one of the major reasons that people use and abuse marijuana is to relieve stress,?according to Samir Haj-Dahmane, Ph.D., neuroscientist and principal investigator on the RIA study. “However, because ...

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

Undersea habitats supporting rare and potentially valuable organisms are at risk from seafloor mining scheduled to begin within this decade, says a new study led by a University of Toronto Mississauga geologist. Mining of massive sulphide deposits near "black smokers"—undersea...

NIDA study identifies genes that might help some people abstain from smoking

...gh this effort make sense because of their role in supporting new neural connections in the brain, more research is now needed to understand the actual mechanisms through which they may increase or reduce the rates of successful quitting. Dr. Uhl says he and his colleagues have replicated this research in ...

How genetic malfunction causes a form of retardation

...ons, which conduct nerve impulses, glial cells are supporting cells that surround neurons and insulate them from one another. In experiments with cultured precursor cells, the researchers found that SHP-2 activates the regulatory pathway that causes genesis of neurons and inhibits the pathway that generates ...

New cigarette designs don't offer lower predicted cancer risks

Although there are grey areas between the definitions of drugs and natural health products in general, the major distinction is that natural health products are derived from...

Scientists identify a gene that may suppress colorectal cancer

...e human ATP5A1 gene have been identified—further supporting its essential role in the cell. “In humans, ATP5A1 is located on chromosome 18, in a region that often exhibits genetic alterations in colon tumors,?says Dr. Linda Siracusa, the other co-senior investigator on the project. “A better understandin...

'Ancestral eve' was mother of all tooth decay
