Researchers discover key mechanism by which lethal viruses Ebola and Marburg cause disease

... to stop these devastating diseases. Filoviruses, named for their threadlike appearance in electron microscopy (filo= thread in Latin), are associated with outbreaks of fatal hemorrhagic fever in sub-Saharan Africa. Viral hemorrhagic fevers are of specific concern because they are associated with high mor...

'Tribbles' protein implicated in common and aggressive form of leukemia

...es of evidence point to a protein called Tribbles, named after the furry creatures that took over the stars... Tribbles gene in mammals. In fact, Tribbles is so named because, when mutated in flies, it causes cells to proliferate uncontrollably. Accumulating evide...

New dyslexia theory blames 'noise'

...as a rejection of the "magnocellular hypothesis" - named for a type of neuron involved in processing fast visual information - that influenced dyslexia research for decades. The researchers found that the magnocellular pathway works normally both in children with dyslexia and in adult poor readers - as...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...rs off viral DNA or RNA. This change in frequency, named the Raman shift for the scientist who discovered it in 1928, is as distinct as a fingerprint. This phenomenon is well known, but Tripp explained that previous attempts to use Raman spectroscopy to diagnose viruses failed because the signal produce...

Engineer ramps up protein production, develops versatile viral spheres

...e the Gaden Award at the ACS meeting. The award is named for Elmer L. Gaden, the founding editor of the journal Biotechnology & Bioengineering, and recognizes the most outstanding paper of the year in that journal. Swartz, who holds the Leland T. Edwards Professorship in the School of Engineering at St...

Telemedicine robots help improve health

...ensland telemedicine researchers are using a robot named Eliza to conquer the tyranny of distance and improve delivery of specialist medical care to the bush. Eliza, who began work at Mt Isa Hospital this week, is a creation of the University's Centre for Online Health ?a world leader in telemedicine res...

Funding to tackle hospital superbugs

...clearance of infection. The new approach has been named "Resolution Therapeutics" by the Cardiff researchers. It is hoped that research in the School of Medicine will lead to the development of other drugs that modify host responses with the view to resolving infection and reducing inflammation in dise...

Antibody extends life of mice with breast cancer

...he animals by more than 50 percent. The antibody, named JAA-F11, targets a particular disaccharide, an antigen known as TF-Ag, which aids the adhesion and spread of certain cancer cells. While the antibody did not kill the cancer cells, it blocked stages of cancer-cell growth that allow the cells to adhe...

A new target for painkillers

... The study in rats found that cone snail toxins named RgIA and Vc1.1 can treat nerve hypersensitivity and pain by blocking a molecule in cells known as the "alpha9alpha10 nicotinic acetylcholine receptor." "The numerous analgesic compounds currently available are largely ineffective" for chronic nerv...

Regulating the nuclear architecture of the cell

...ression, known as suppressors of variegation, were named Su(vars). The gene family known as Su(var)3-9 codes for proteins that chemically modify certain histones in the nucleosomes. Su(var)3-9 proteins attach methyl groups to the histone labeled H3 at its ninth amino acid residue, which is a lysine. In...

Small, smaller, smallest -- The plight of the vaquita

... when the vaquita was scientifically described and named as a species, the Mexican Government has finally taken specific actions to try to prevent its extinction. On 29 December 2005 the Ministry of Environment declared a Vaquita Refuge that contains within its borders approximately 80% of all verified vaq...

'Best of both worlds' -- Targeting a single gene could inhibit bone decay and stimulate bone growth

...niors with osteoporosis." Dr. Choi was recently named the 2006 winner of Korea’s prestigious Ho-Am Prize for his work in osteoimmunology. The award recognizes scholars and researchers who make outstanding achievements by international standards while encouraging future activities of even higher levels a...

Genetic surprise confirms neglected 70-year-old evolutionary hypothesis

...enly recalled an off-hand comment from a scientist named Hermann J. Muller in a paper 60 years earlier. Muller speculated that perhaps since the sterility in the flies is so recessive--meaning it's almost completely non-functional--perhaps the gene in question has jumped clear off the chromosome. "It had ...

American scientist's research of life's first cells

...orth America and the Grand Prize winner, today was named to receive the $25,000 GE & Science Prize for Young Life Scientists, supported by GE Healthcare and the journal Science , which is published by AAAS, the nonprofit society. Chen will receive her award in Stockholm, Sweden, on Monday, 11 Decembe...

First major study of mammalian 'disorderly' proteins

...is critical for function. For example, one protein named p27 initially looks like a Slinky TM toy. However, when p27 goes to work, it puts a vise-like grip on an enzyme that otherwise would promote uncontrolled cell division. The St. Jude team developed a technique that uses heat to isolate IUPs in lar...

First Quantum Grant to fund stem cell repair of damage from stroke

The National Institutes of Health has named researchers at Baylor College of Medicine (BCM) and Rice University in Houston as the first and only recipients of the inaugural Quantum Grant for their international research initiative to regenerate damaged brain cells and blood vessels for the tre...

Discovery of the first resistance gene to rice yellow mottle virus

...F(iso)4G, involved in cellular RNA translation and named Rymv1, appeared to be the best candidate. Validation of the function of this resistance gene was performed by genetic transformation. For this, a line of resistant rice was modified by transgenically introducing the allele for susceptibility of this ...

New bird discovered on unexplored Columbian mountain

...supported by the BP Conservation Programme. It was named "Yariguies Brush-Finch," with the scientific name ...sts Club (Vol. 126: June 2006). The new bird is named for the Yariguies indigenous people who formerly inhabited the mountain range where the bird was fou...

Hair-growth drug artificially lowers PSA levels in prostate cancer screening, study finds

...onverted to dihydrotestosterone (DHT) by an enzyme named 5-alpha reductase. DHT activates the genes responsible for the development of male-pattern hair loss. Finasteride interferes with this process by blocking 5-alpha reductase and preventing the conversion of testosterone to DHT. The data i...

An AIDS-related virus tricks cells to become tumors, new Penn study finds

... to a pathway in all cells whereby a protein aptly named ubiquitin binds to cellular proteins and marks them for degradation. This process can be likened to putting out the garbage for disposal. Ubiquitylation and degradation involve a complex set of proteins in addition to ubiquitin. "We found that t...
