Liver regeneration may be simpler than previously thought

...re not present in regenerating livers, it might be easier to stimulate liver regeneration by only activating the other identified proteins. "These results are very encouraging," Karp says. "Not only did we discover that the number of proteins involved in liver regeneration is relatively low, but they do...

Synthetic peptide targets latent papilloma virus infections

...the development of the peptide, but should make it easier for drug developers to design a molecule that can nudge Brd4 aside so as to bind and block the action of E2. Botchan, who has studied DNA replication in viruses for 30 years to understand similar processes in higher organisms, says that such a drug...

Stem cells act through multiple mechanisms to benefit mice with neurodegenerative disease

...s, although the embryonic stem cells were somewhat easier to "scale up" into large quantities. Both types of human stem cells invoked the same range of multiple, collaborative mechanisms. Neither type of human stem cell created tumors, deformation, a worsening of symptoms, or gave rise to inappropriate cell...

Prehistoric origins of stomach ulcers uncovered

...frica at the same time as early humans it makes it easier to examine some of the controversial questions about human migration. For example we could use our understanding of the bacteria's spread to gauge poorly understood human population shifts in Europe, Africa and Asia." ...

Tracking sperm whales and jumbo squid

...bo squid that are in some way compromised and thus easier to capture," the authors wrote. "This research provided a unique opportunity to learn more about two species that are very difficult to study in their natural habitat," Davis noted. "In the future, this co-tagging approach should yield new insight...

Researchers identify gene involved in dog size

...rsification among domestic dog breeds by making it easier for humans to maintain them in the crowded confines of developing villages and cities, as well as making them more transportable during trade and migration. Future aims of the study are to identify genes that control other aspects of canine morpho...

Gene tests and brain imaging reveal early dementia

...lzheimer's with any certainty, but things are made easier if you know who runs the greatest risk," she says. "If genetic mapping, MRI and cognitive tests all suggest approaching Alzheimer's, it might be an idea to start a course of treatment." ...

Using nanomagnets to enhance medical imaging

...ules that might make MRI imaging more powerful and easier to perform. The new paper resolves a debate in the literature by showing that iron-containing magnets just two nanometers wide, dissolved in water, do provide reasonable contrast in non-clinical MRI images—as long as the nanomagnet concentration is b...

Helium helps patients breathe easier

...wn the frequency of breathing while making the air easier to breathe. This combined effect reduces the amount of air trapped in the lungs during exercise. "This means they don't have to work as hard to breathe and they are not so short of breath during exercise, which allows them to do more," said Dr. Ne...

Study offers clues to 'Broken Heart Syndrome'

...e" remain a mystery, but doctors will soon have an easier time recognizing and treating this rare, life-threatening condition, thanks to data being reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9?2, 2007, in Orlando, FL. Research...

'Personality-gene' makes songbirds curious

...s are hard to control experimentally. Birds are an easier target for research and indeed, they also have different personalities. An international team of researchers have now found evidence for the existence of a "curiosity-gene" in a songbird, the great tit (Parus major). The gene (Drd4) carries the bui...

Treating HIV in war zones -- Public health emergencies need rapid advice from WHO

...a, thus reducing travel requirements and making it easier and safer for staff and patients to access the clinics in times of insecurity Establishing links with HIV care programs in neighboring regions, allowing displaced patients to continue to receive care Educating patients on the importance of not co...

Researchers demonstrate way to control tree height

... semi-dwarf fruit trees produce more fruit that is easier to harvest. The improvements in cereal yields have been credited with preventing the starvation of millions. ...

Potato wart eyed as risk to potato production

...or potato seed production. "Potato wart is much easier to prevent than it is to control," Franc said. "It is highly critical that we prevent the introduction of the potato wart pathogen to production areas, and, where it is already introduced, to limit its spread," he said. "While regulatory action i...

Mutating the entire genome

Brightening prospects of using fluorescent nanotubes in medical applications

...row range of wavelengths, or colors. This makes it easier to pick out their signal against background noise. Furthermore, they produce light in a part of the spectrum – the near infrared where skin and other tissue is transparent – that allows the nanotube light to stand out. Nanotubes are made entirely...

Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...gy required for a cell membrane to bend, making it easier for the virus to infect immune cells. The finding, in press in Biophysical Journal, will provide vital data to conduct future computer simulations of HIV dynamics to help further drug discovery and prevent deadly infections. “We found that HIV fusio...
