Yale researchers find environmental toxins disruptive to hearing in mammals

...sound localization abilities. The present findings confirm that their hearing is altered in mammals. "Since many marine mammals use echolocation or sonar to get around, this could be contributing to whales and dolphins beaching and hitting ships," Santos-Sacchi said. ...

Cyclosporine inhibits hepatitis C virus in vitro

...ed therapy," the authors report. In addition, they confirm antiviral activity by the drug in cell cultures, having found that, "combination of Cyclosporine and interferon achieve better antiviral effect than either one alone." Of note, considerably more patients taking Tacrolimus had to reduce or stop the ...

Dogs keep dying: Many owners unaware of toxic dog food

...cting as many livers as possible from dead dogs to confirm cause of death, tracking dogs that have died and f...e a liver specimen sent to Cornell to definitively confirm the pathologic changes in the liver unique for aflatoxin toxicity, such as fatty degeneration of ind...

AIDS drug from sunflowers

...lass of AIDS drugs. Initial clinical tests seem to confirm DCQA's potential. 'We need these substances to expand our arsenal of effective weapons against the disease,' Dr. Esther Vogt of the Immunological Out-Patient Service of Bonn University Clinic adds. 'It remains to be seen, however, whether they will ...

New study reveals promising osteoporosis treatment

...s will be needed, ultimately using human trials to confirm the results. Dr. LeGeros' paper, Effect of Mg/Zn/F-CaP Supplements on Bone Properties: Phase 1, describes initial results of her research, which is funded by a four-year, $2 million grant from the National Institute of Biomedical Imaging and Bioen...

Losing sleep undoes the rejuvenating effects new learning has on the brain

...rain Scientists already know ?and most of us can confirm from firsthand experience -- that lack of sleep impairs cognitive function. Sleep-restricted individuals have a shorter attention span, impaired memory, and a longer reaction time. "Sleep is necessary for general health, but it now appears that the b...

New analysis shows three human migrations out of Africa

...ion researchers thought had occurred.The new data confirm an expansion out of Africa to 700,000 years ago that was detected in the 2002 analysis. "Both (the 1.9 million and 700,000 year) expansions coincide with recent paleoclimatic data that indicate periods of very high rainfall in eastern Africa, maki...

FSU biologist says new dinosaur is oldest cousin of Tyrannosaurus rex

...vertebrate musculoskeletal system, Erickson helped confirm the tyrannosauroid lineage of the two specimens by noting, among other features, the characteristic long hip, the U-shaped teeth and the fused nasal bridge. While they weren't exactly T. rex look-alikes, they were definitely family. But there were m...

Scientists reveal how deadly toxin hijacks cells

...s," the scientists were able to zero in on SV2. To confirm that result, they acquired mice that were genetically engineered to carry reduced amounts of SV2. Without that protein around, the researchers found that botox was unable to wreak havoc. Co-author Felix Yeh, a UW-Madison graduate student who works w...

Rutgers researchers find fat gene

...PAH1 that made it. Carman and his group went on to confirm the link by introducing the yeast gene into bacteria, with similar results. The researchers showed that the enzyme encoded by the PAH1 gene looks and acts very much like the lipin found in mammals. The yeast PAP enzyme shares a high resemblance to t...

Utah researchers confirm chromosome may harbor autism gene

...Finnish studies, Coon said. "It was remarkable to confirm the Finnish studies," she said. "Our results were so close to their evidence, we thought it was important." Autism is a behavioral disorder that strikes before age 3 and is characterized by impaired ability in social interactions and communication....

Darkness unveils vital metabolic fuel switch between sugar and fat

...to those kept in the regular light-dark cycle. To confirm the connection, the team injected 5'-AMP into mice exposed to a regular light-dark cycle. Three to four hours after injection, mClps was expressed in the livers of these mice and further tests showed expression in all tissues except the brain. I...

DNA conclusive yet still controversial, Carnegie Mellon professor says

...spect through other evidence and then using DNA to confirm their case. Some critics claimed that this practice could snag an innocent person, but Roeder has demonstrated through her own research that the likelihood of a false hit are miniscule -- in one case, for example, it was about 1 in 26 quintillion, a ...

Infused spleen cells found not to impact islet recovery and reversal of type 1 diabetes in mice

...in human disease progression has been difficult to confirm because usually enhancers are located in the 98 percent of the human genome that does not code for protein, termed non-coding DNA. Unlike DNA sequences that code for protein, non-coding DNA, sometimes referred to as "junk" DNA, follows few rules for ...

Junk DNA may not be so junky after all

...in human disease progression has been difficult to confirm because usually enhancers are located in the 98 percent of the human genome that does not code for protein, termed non-coding DNA. Unlike DNA sequences that code for protein, non-coding DNA, sometimes referred to as "junk" DNA, follows few rules for ...

Powerful new tool for studying brain development

... researchers will be able to do certain studies to confirm hypotheses using a computer interface that links our data to many other kinds of gene information, without the need to go into a regular laboratory." The BGEM is a growing, encyclopedic collection of tens of thousands of images as seen through a m...

Carbon nanotubes that detect disease-causing mutations developed by Pitt researcher

...ed fluorescently labeled DNA molecules in order to confirm that DNA had attached to the nanotube surfaces and was subsequently hybridized, or matched to its complementary DNA. "We have found that electrical measurement of carbon nanotube devices produce sensor results that are comparable to state-of-the-art...

Rochester scientists develop fast-working biosensor

...example, could use the technology in his office to confirm a streptococcal infection in a patient with a sore throat. The Rochester research team calls the technology "arrayed imaging reflectometry." The system utilizes a silicon chip that is made so that laser light reflected off the chip is invisible unle...

Largest study of human 'interactome' reveals a novel way

...omputerized sleuthing to laboratory experiments to confirm those findings, we expect to be able to eventually fill in many blanks in human protein-protein interactions." All the analyses were primarily carried out at the IOB, a nonprofit research institute founded by Pandey in May 2002. The Human Protein R...

'Virus chip' detects new virus in prostate tumors

...ade with the same DNA-hunting "virus chip" used to confirm the identity of the SARS virus three years ago. While the genetics of prostate cancer are complex, one of the first genes implicated in the disease was RNASEL, a gene that serves as an important defense against viruses. Given the anti-viral role of ...
