Genetic therapy reverses nervous system damage in animal model of inherited human disease

...n humans might be years in the future. ### Video comparing a cat with AMD to one that had been given gene therapy is available at www.mrw.interscience.wiley.com/suppmat/0364-5134/suppmat/2005/57/v57.3.355.html. ...

Reservoirs may accelerate the spread of invasive aquatic species, researchers say

...Lee, and Vander Zanden argue for research aimed at comparing rates of invasion in freshwater lakes and reservoirs that are in similar geographic regions, to determine whether the rate in reservoirs is indeed higher, as predicted. ...

Birds brains reveal source of songs

...creativity, generating the variations, rather than comparing them." To test this theory, Fee's team studied finches that were just old enough to begin their vocal explorations. The researchers temporarily inactivated the part of the AFP connecting to the motor system used in producing songs. That inactivation...

Multiple Campylobacter Genomes Sequenced

...and how to treat the infections caused by them. By comparing genome sequences, scientists can learn much more about what makes a bacteria tick than they can learn from a single sequence. Derrick Fouts and his colleagues have taken this comparative approach with Campylobacter. Infection with a Campylobacter sp...

Pathogen-Mimicking Vaccine As Strategy For Cancer Therapy

...djuvants that have been tested in other trials. By comparing single variables in parallel we believe we can develop effective cancer vaccines in a much shorter time than the conventional approach of trying variables sequentially." The CVC has clinical research sites in Australia, Belgium, Germany, Japan, Switz...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

..., Greg Elgar and colleagues attack this problem by comparing the non-coding sequences of the human and the pufferfish. Since the last common ancestor of these two species existed 450 million years ago, the authors reasoned that non-coding sequences conserved between them are likely to be fundamental to verteb...

RNA project to create language for scientists worldwide

...cabulary and system for describing, cataloging and comparing their findings. An international team of RNA scientists, known as the RNA Ontology Consortium, has now been formed to do just that. "The consortium will develop a common vocabulary and scientific concepts relating RNA structure and function to allo...

The Bacteria's guide to survival

...or the sexually transmitted disease gonorrhea. By comparing cells infected with normal N. gonorrhoeae to those infected with a mutant strain with defective pili, the researchers found a subset of 52 host genes that had higher activity when the host was infected with the normal bacteria, suggesting that the pu...

Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

...e fish colonize a new freshwater location." Also, comparing what happens to the ectodysplasin signaling molecule when its gene is mutated in humans, and in fish, shows a major difference. The human protein suffers "a huge amount of molecular lesions, including deletions, mutations, many types of lesions that ...

Scientists reveal molecular secrets of the malaria parasite

...exploring how the Plasmodium genome hasevolved. By comparing four sequenced genomes (the human malaria P.falcip...ito.Hall's group identified the gene regulation by comparing the genesexpressed in the sexual stage transcriptome with the proteomes of boththe sexual stage and ...

Researchers trace evolution to relatively simple genetic changes

...e fish colonize a new freshwater location." Also, comparing what happens to the ectodysplasin signaling molecule when its gene is mutated in humans, and in fish, shows a major difference. The human protein suffers "a huge amount of molecular lesions, including deletions, mutations, many types of lesions that ...

Study: Soap And Water Work Best In Ridding Hands Of Disease Viruses

The largest, most comprehensive study ever done comparing the effectiveness of hand hygiene products shows that nothing works better in getting rid of disease-causing viruses than simply washing one’s hands with good old-fashioned soap and water. Among the viruses soapy hand washing flushes down the drain ...

Scientists decipher genome of fungus that can cause life-threatening infections

...ed the geneticdeterminants of its pathogenicity by comparing the genomes of twoclosely related strains of significantly different virulence. "Notonly have we established a genomic platform for the further study ofthis increasingly important pathogen, but the data from the two strainsmay provide insight into w...

Genome-wide mouse study yields link to human leukemia

...s, both major components of the immune system. In comparing the mice in the pre-leukemic stage and those with ALL with normal mice, researchers found that methylation, a chemical process that adds methyl molecules to DNA, silenced a number of genes ?but only in the mice with full-blown ALL. Further tests rev...
