Study shows hope for ridding lakes of clawed invader

...rpenter, has yielded very promising results. "It seems to be working. The aquatic plants are back. That's good because that's fish habitat, and the fish populations are returning to what they were before the rusty got into the lake sometime in the 1980s," says Carpenter. The two-pronged approach to rid...

Traditional Chinese medicine for diabetes has scientific backing

...rn helps lower blood sugar levels. In addition, it seems berberine can help reduce body weight". Current medicines for treating type 2 diabetes include metformin and the TZD group of drugs. However, alarge number of patients cannot tolerate metformin and the TZDs can cause undesirable weight gain.Therefo...

Progress being made in exploring potential use of stem cells to treat heart disease

...titute for Regenerative Medicine. "The adult heart seems to have reservoirs of cardiac progenitor cells--adult stem cells that are destined to become cardiovascular cells--that may be able to replace a slow loss of cells over a lifetime. The coming years will undoubtedly bring new developments and technolo...

UF scientists test improved gene therapy method for hereditary heart conditions

...e that AAV-8 didn't," Byrne said. "Right now AAV-9 seems to be our best solution for heart problems. "The primates were done to give us insight into how this could be used in children," he said, adding that UF researchers hope to launch a trial in patients with Pompe disease early next year. "Many of the...

Researchers map out networks that determine cell fate

...for leukemias, in which a persistent mixed lineage seems to drive cancerous proliferation. Although the researchers worked only with blood-forming stem cells, they suspect that the same basic regulatory principles govern cell type determination in other tissues such as skin, brain and intestine. "We see...

New genes implicated in rheumatoid arthritis

... genetic component, RA's occurrence among siblings seems to be random. In the quest to identify disease-specific gene expression profiles in patients with RA, researchers at the University of Michigan Medical Center turned to an ideal population: genetically identical, disease-discordant twins. The Jul...

Marine 'dead zone' off Oregon is spreading

... a change in intensity and timing of coastal winds seems to play a significant role in these events. "We're seeing wild swings from year to year in the timing and duration of winds favorable for upwelling," said Jack Barth, an oceanographer with PISCO and the OSU College of Oceanic and Atmospheric Science...

Selenium-protein deficiency raises prostate cancer risk

... colorectal and prostate. "The problem is, nobody seems to know how the mechanism works, and that's not trivial," said Alan Diamond, professor of human nutrition at the University of Illinois at Chicago and principal investigator in an ongoing multidisciplinary study set up at UIC to help answer that ques...

Internal body clock dictates timing of different types of stroke

The internal body clock, or circadian rhythm, seems to influence the timing of different types of stroke, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry. The research team analysed data from almost 13,000 patients who had had one of three types of ...

Nicotine exposure during development leads to hearing problems

...in the brain that are sensitive to nicotine, which seems to occur when humans or animals are exposed to the substance during development. The study appears this week in the early online issue of the European Journal of Neuroscience. Children with auditory processing deficits can have a number of hearing-...

A protein complex that untangles DNA

... repair process. Moreover, the Smc5/6 complex also seems to be required for the disentanglement of undamaged chromosomes before cell division. If these tangles, which are a natural consequence of the DNA copying process, are left unresolved the chromosomes cannot be separated and sent to the two nascent da...

When it comes to gene transcription, random pauses aren’t quite so random, study finds

...t another nearby position," he said. "So the pause seems to be sequence dependent. It's not always the same duration every time, but it's more likely to pause at one of these sites than at any other sites in between, so it's not just some random phenomenon that happens every once in a while. If I'm running...

Researchers offer clues to how leaves patterns are formed

...oot. With our piece of the puzzle added, it indeed seems the same mechanism is responsible for all these events." What Scarpella and his research team--Dr. Thomas Berleth's group from the University of Toronto and Dr. Jiri Friml from the University of Tuebingen--discovered has interested scientists arou...

Ecosystem services and invasive species

"It seems only appropriate that while we are all concerned about loss of biodiversity in the rainforests and coral reefs that we at least start to learn what is in our own backyards. Tennessee and neighboring states contain the world's richest diversity of fr...

Loosen up, DNA: Leukemia gene changes genetic packaging

...ientists had considered. The signaling system thus seems unique because it can both cause cancer directly, or knock out genetic mechanisms that suppress cancer. "A molecule that is both an oncogene and that also antagonizes a tumor suppressor mechanism is pretty powerful," Li said. "Most genes involved i...

Leptin found to control appetite and limb development in frogs

...g brain to suppress appetite. But the hormone also seems to play a role in the complex signaling that turns a finned tadpole into a four-legged frog, according to Robert Denver, an associate professor of biology at the University of Michigan. Denver's team gave frogs a dose of leptin at various stages of ...

Parallel evolution: Proteins do it, too

...g double-stranded RNA. After duplication, one copy seems to retain the activity of degrading double-stranded RNA while the other copy has adapted to changed pH in the small intestine so it can better digest food." Even after clearly demonstrating parallel evolution in this case, Zhang believes the phenome...

According to Dr. Ericsson, who is also a Research Fellow of the Royal Swedish Academy of Sciences, this approach might one day ...
