Scientists to track impact of Asian dust and pollution on clouds, weather, climate change

...ven though these experiments shed new light on the inner workings of the olfactory system, their greatest significance is that they provided proof of principle that this new model can be used to study a wide variety of questions involving the brain. "There are a lot of tools that work well in simpler sy...

Cheaper, better disease treatments expected from faster approach to developing antibodies

...n E. coli bacterium becomes tethered to one of its inner surfaces, or membranes. Small "errors" in the genes that produce antibodies are introduced. These changes result in slightly altered antibodies that may attach more strongly to a disease protein. The interaction between the antibody and the disease p...

Stem cell transplants explored at Stanford as a possible treatment for hearing loss

Buckyballs used as 'passkey' into cancer cells

...branes, form a protective cocoon around the cell's inner machinery and its DNA blueprints. "Drugs are far more effective if they're delivered through the membrane, directly into the cell," said lead researcher Andrew Barron. "Viruses, which are often toxic, long ago developed ways of sneaking through ce...

Ultrathin films deliver DNA as possible gene therapy tool

...h the effect that outer layers are released before inner layers. By placing one gene in the outer layers and another in the inner layers, they can deliver different products sequentially. "This kind of control is extremely diff...

Nanoparticles for delivery of prostate cancer treatment

...eptor tissue factor (TF) found on cells lining the inner surface of blood vessels in tumors but not in normal tissues. The Icon binds to TF more strongly and specifically than a natural antibody. Because the Icon acts through the blood, it can reach metastatic tumors throughout the body, which is critical ...

Stem cell therapy shows promise for rescuing deteriorating vision

...wn identity, but they migrate within the outer and inner retina" where they seem to confer some protection to the light-sensing cells that typically die in the course of degenerative eye disease. For researchers, the work is intriguing because the progenitor cells come from the brain itself, and not fro...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

Cholera pathogen reveals how bacteria generate energy to live

... of the enzyme’s machinery ?are all located on the inner side of the membrane, which corresponds to the "intake" port of the ion pump. The second paper was published in the Journal of Biological Chemistry. In this study, Barquera focused on structures, known as flavins, within the enzyme that carry the ...

New imaging technique tracks traffic patterns of white blood cells

...thods, the new research displays the migration and inner workings of white blood cells in the small veins and bone marrow of mice. "Intravital micropscopy (IVM) has contributed enormously to the recent mechanistic advances in leukocyte trafficking," wrote Mount Sinai School of Medicine researchers lead au...

Gene key to taste bud development identified

...iated and whether stem cells in the brain, eye and inner ear differentiate into specialized nerve cells. Taste bud cells, much like skin cells, continually slough off and are replaced by new ones. So the new findings not only provide insights into the interactions between SOX2 and tongue stem cells durin...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

In the majority of macular and retinal degenerative diseases, such as age-related macular degeneration and retinitis pigmentosa, it is the loss of photorecep...

Altered perception of reward in human cocaine addiction

The fMRI results also revealed that non-addicted subjects responded to the different monetary amounts in a graded fashion: the higher the potential reward, the greater the response in the ...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

"In addition, on average across all the patients, cerebellar choline levels increased by about 20%, while levels of NAA in the cerebellar and frontal region of the brain and frontal choline significantly increased by about 10%. Brain volume ...

Effective treatment is hampered by poor understanding of how the virus infects the stroma, says Deepak Shukla, assistant professor of ophthalmology and visual science and microbiol...

Cell wall of pneumonia bacteria can cause brain and heart damage
