Evidence for omega 3 fats less conclusive than we thought, say experts

...arly, say the authors. However, it is probably not appropriate to recommend a high intake of omega 3 fats for people who have angina but have not had a heart attack. To understand the effects of omega 3 fats on health, we need more high quality randomised controlled trials of long duration that also report the ...

Study finds drug may cut down involuntary movements

...carefully with patients and caregivers to find the appropriate dose. Side effects were seen in about 25% of subjects in the study. The most common side effect was sleepiness, but restlessness, slowed movement and depression were also seen in some subjects. Suicide is common in Huntington's disease, and one su...

Study suggests that publicly available genome data may contain small but significant errors

...whole-genome assembly. The authors show that with appropriate experimental conditions, array hybridization data can be used to establish a physical distance between unique arrayed probes--a sequence of DNA which in this case was 70 base pairs long. Each of the 70 base pairs is unique in the target organism's ge...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...ty to develop into different types of cells in the appropriate environment. One donation can produce billions of MSCs. The cells can be stored for years in a frozen state, ready to be used when they are needed." Adult stem cells are designed by nature to perform tissue repair in a mature adult. It is believed ...

Common practices at petting zoos put visitors at risk

...eople need to be aware of these risks and take the appropriate precautions such as washing their hands after visiting," says Fred Angulo of the Centers for Disease Control and Prevention (CDC). Unfortunately, according to two other studies being presented at the meeting this week, many visitors do not even enga...

Potential heart benefit found in stem cells

... the cells. Further analyses of the cells revealed appropriate cardiac gene expression and action potential, as well as sustained and significant positive cardiac troponin-1, a calcium-regulated protein in muscle tissue, and connexin 43, a protein that assists in intracellular interactions The in vitro data sug...

Do plants have the potential to vaccinate against HIV?

...the HIV-1p24 antigen produced in this way elicited appropriate immune response in mice. The results have important implications for the economic viability of using plants as bioreactors to produce vaccines against HIV and other diseases. According to Obregon: "Using antibody-antigen fusion molecules may represe...

Plant-derived vaccines safeguard against deadly plague

...l antigens in a native form that will allow for an appropriate immune response against a bacterial pathogen." Mason. Critical to the success of the study was a collaboration set up with Anatoli Giritch, Victor Klimyuk and Yuri Gleba, who originally developed the plant expression system at Icon Genetics, locate...

BioMed Central launches Biology Direct

This novel review process gives the author the opportunity to discuss points raised directly with the reviewers, and to revise their manuscript as much or as little as the...

How nice, brown rice: Study shows rice bran lowers blood pressure in rats

...ir study with good controlled experiments using an appropriate model.?/p> It’s still not clear whether simply eating more brown rice, which retains some of its bran, would reduce the risk of heart disease. However, previous research in humans, as well as animals with high cholesterol, does suggest that certa...

Predicting successful outcomes in living-donor liver transplants

In another study in the same issue, researchers led by Christoph Jochum, M.D. of the University Duisberg-Essen in Essen, Germany investigated ICG elimination, galactose elimination capacity (G...

UC San Diego biologists solve plant growth hormone enigma

...any new genes to the plant, just changing when the appropriate auxin genes were on or off could alter growth. For example, to make seedless tomatoes, one could activate auxin in the floral organs before fertilization has taken place." Applying auxin to the flowers by hand can also induce seedless tomatoes, or ...

Stanford snake venom study shows that certain cells may eliminate poison

...ptor they had on the cell surface and released the appropriate proteins, which, Metz said, went on to "degrade and thus eliminate the venom, or at least make it less toxic." The wild-type mice were able to withstand 10 times the dosage of this venom than the mast cell deficient mice could, further indicating t...

UCLA scientists strengthen case for life more than 3.8 billion years ago

...ch in Greenland. "We have shown that the rocks are appropriate for hosting life. "Everything from the basic geology to the analysis in the original report (in Nature) has been challenged," said Manning, who has expertise in areas that have become central to the debate, including the chemistry of water and the ...

Rehydrate -- your RNA needs it

...nsor---detecting cellular signals and carrying out appropriate reactions in response. In fact, there are many more so-called non-protein coding RNAs in the cell (around 100,000 in humans), which are not translated into protein, than there are protein coding messenger RNAs (about 25,000), making these vast number...

A dichotomy in migration patterns found for sea turtles in east Atlantic
