NT researchers discover breakthrough in malaria treatment

...hin 6 weeks. This "post treatment prophylaxis" is similar to the approach of giving travelers regular medication to protect them from infection, but can be applied opportunistically to people at high risk of infection in poor tropical communities." he added. A concern with such a policy is that the resis...

How appetite-stimulating brain cells work overtime during fasting

... is introduced." The mechanism involved is very similar to the one that regulates core body temperature in peripheral body tissues, Diano added. Thyroid hormones are known to play major roles during development as well as in adulthood, the researchers said. In adults, the thyroid gland is essential to ...

Imaging techniques permit scientists to follow a day -- or four -- in the life of a cell

... inside the cell. This microinjection technique is similar to those that are used to create cloned and transgenic organisms, and it can also be applied to more complex assays--including laser photobleaching and fluorescent speckle microscopy--that yield specific insights into cellular processes. A second ...

NIAID DNA vaccine for H5N1 avian influenza enters human trial

...18 pandemic. The DNA vaccine used in this study is similar to other investigational vaccines evaluated by the VRC that hold promise for controlling other viruses, such as HIV, Ebola, SARS and West Nile. "An effective H5N1 influenza vaccine would provide a potentially life-saving advance against a global ...

Loss of a universal tRNA feature reported

...adding histidine to tRNA differs considerably from similar enzymes in other organisms. We have indeed been able to detect an impact on particular regions of the histidyl-tRNA synthetase that are critical for recognizing tRNA." The researchers used bioinformatic tools such as a computer script ?specific...

Are one-third of costly implanted heart devices unnecessary? New study suggests yes

...ed ICDs were no less likely to die than those with similar test results who didn't receive ICDs. "This is the first study to demonstrate that a subset of patients who meet current criteria for defibrillator placement may not benefit at all from ICDs," says Paul Chan, M.D., M.Sc., senior author and a fell...

McBride shows DNA detective work with paper-eating bacteria that 'glide'

... doesn't eat cellulose, but it is able to digest a similar carbohydrate polymer, chitin. Like cellulose, chitin, which is found in the hard shells of lobsters and insects, is also difficult to break down. McBride hypothesizes that digestion of cellulose and chitin may also be linked to cell movement, or mo...

UTSA Earth and Environmental Science Assistant Professor Hongjie Xie and doctoral student Burcu Cicek are analyzing data collected in December following a two-week trip to the region. The pair were part of ...

Robotic exoskeleton replaces muscle work

...ons for rehabilitation and physical therapy, and a similar approach could be used by other groups who do build such technology. "This could benefit stroke patients or patients with incomplete injuries of the spinal cord," said Daniel Ferris, associate professor in movement science at U-M. "For patients th...

Africa's first large-scale HIV vaccine study launches

...immune response to the parts of the virus that are similar between different strains of HIV-1." The study is known as a phase IIb or "test of concept" efficacy trial because it enables researchers to determine whether the test vaccine prevents HIV infection, results in lower HIV levels in those who become ...

Chlamydia vaccine a step closer to reality

...en developed it could be administered via a patch, similar to ones used by smokers for nicotine. "Patches are a good way to deliver proteins to a part of the body's immune system and they are also easy and user-friendly." He said with rates of Chlamydia infection in some Australian communities as high ...

Anti-wrinkle compound causes pathological reaction in skin cells

...lifts." This compound, as well as other chemically similar ones, are also found in cosmetics, creams, lipstic... 25% after 24 hours in the case of a concentration similar to the one resulting from normal use of an antiwrinkle cream. The thickening of the skin induced by ...

Researchers find gene mutation that causes infertility in male mice

...covered, the researchers say they can now look for similar mutations in the DNA of infertile men. "If you consider infertility a disease, you can't study it like you would other diseases, because the affected people can't reproduce," said John Schimenti, director of Cornell's Center for Vertebrate Genomics ...

A new study of living cells could revolutionize the way we test drugs

...daily functioning of the cell to be monitored in a similar way to a cardiograph showing the workings of a human heart. With funding from the Engineering and Physical Sciences Research Council (EPSRC), Professor Andre Geim at the University of Manchester and his team have set out to make the first measurem...

Cancer-killing invention also harvests stem cells

...r King envisions that the device would use a shunt similar to the type used in hospitals today. This shunt would reside on the exterior of the arm or be implanted beneath the skin. Some of the blood flow would bypass the capillary bed and instead go into the shunt, which could remain implanted for many wee...

Chemo combination improves survival in asbestos-related cancer

...w they were exposed to asbestos as young men, with similar issues for their partners." According to the U.S. Environmental Protection Agency, 10 percent to 15 percent of schools and other public buildings in the United States contain asbestos insulation. Although safety measures for working with asbest...

New mechanism for nutrient uptake discovered

...nce plants, animals, bacteria, and fungi all share similar genes for this activity, the scientists believe that the same feature could occur across species. The discovery, published in the February 11th on-line edition of Nature, has widespread potential—from understanding human diseases, such as kidney func...

Study shows hope for early diagnosis of Alzheimer's

...lop a hand-held device that can be used to conduct similar evaluations as those done by the Rowan/Penn//Drexel group. “We don’t envision this replacing a neurologist,?Polikar said. “We hope it can serve as a first test for those folks who don’t have access to research facilities.?If the initial test indic...
