New device could cut chemotherapy deaths

...chnology." The Fibrasorb technology is a flexible fully resorbable device that can be formulated as a bead, a fibre or mesh, or as a tube put into the body which leads outside the body and through which drugs can be fed. For the pre-clinical studies, funded by the Department of Health, Dr Perera will be ...

Trial success for diabetic nerve therapy

...y 2025. The causes of diabetic neuropathy are not fully understood but researchers investigating the effect of glucose on nerves believe it is likely to be a combination of factors. ...

Mayo Clinic researchers discover cancer cells may move via wave stimulation

...ancer cells: circular waves. Until now, no one has fully understood the function of these waves. The Mayo findings in the current edition of Cancer Research http://cancerres.aacrjournals.org/current.shtml are the first to show one role the waves play. They selectively round up activated growth-promoting ...

Even fish don't swim well when they're young!

...her types of fish. "Many fish larvae hatch without fully formed pectoral fins and all hatch without a swimbladder, so similar problems could occur for them", predicts Müller. This conclusion is all the more profound because it refutes two previous theories of poor hatchling swimming, one focusing on the b...

Vegetables inhibit growth of prostate cancer in mice with human tumors

...orth Pacific involves processes that are still not fully understood. Concentrations of DDE (the main breakdown product of DDT) and PCBs in both black-footed and Laysan albatrosses were 130 to 360 percent higher in the samples Finkelstein collected in 2000 and 2001 than in samples collected by previous re...

Albatross study shows regional differences in ocean contamination

Weighting cancer drugs to make them hit tumors harder

...e bloodstream before their anti-cancer effects are fully achieved. Overcoming this limitation by adding macromolecular weight is not a new concept, but determining the precise weight to achieve optimal drug concentration has proved difficult, he said. Chilkoti and his colleagues in the department of biome...

New method for identifying microbes

...idating this complexity is essential if we want to fully understand the roles microbes play in global cycles, make use of their enormous metabolic capabilities, or easily identify potential threats to human health." Growing cultures of microbes to identify species is slow and error prone as the culture co...

Biofuels can replace about 30 percent of fuel needs with significant research and policy effort

...in how biofuel is processed. Their vision is for a fully integrated biorefinery, which is designed to take advantage of advances in plant science and innovative biomass conversion processes and equipment to produce fuels, power and chemicals from biomass. The biorefinery would work much like a petroleum r...

Hap1 protein links circulating insulin to brain circuits that regulate feeding behavior in mice

...e brain's feeding signals, but scientists have not fully understand how these hormones interact with the brain circuitry. Neurotransmitters in the hypothalamus, including GABA (gamma aminobutyric acid), are known to be an important part of the pathway that regulates feeding behavior. Scientists at Emory ...

Growth factor-promoting angiogenesis expressed in tumor cells and normal neurons

...types of brain injury, but its significance is not fully understood. Dr. Howard A. Fine from the National Cancer Institute/National Institute of Neurological Disorders and Stroke at the National Institutes of Health and colleagues designed a study to investigate whether, as a result of tumor-induced brain ...

Sociality of sweat bees evolved simultaneously during climate change

...s at low latitudes and in warmer regions are often fully social, whereas they are solitary at higher latitudes and altitudes, which are colder." Warmer regions have longer growing seasons, he explained, which allows two broods to emerge instead of one. The first brood (workers) helps raise the second bro...

Polymer aids in blood clotting, pointing way to new treatment

...acteria -- long thought to be for storage -- was a fully operational organelle. It contained pyrophosphatase, a pump-like enzyme that allows proton transport. He named it the acidocalcisome for its acidic and calcium components. Docampo has since found virtually identical pyrophosphate-containing pouches ...

Researchers now able to look deep into heart to view triggers of a heart's beat

...t contains the chromosomes. By the time the egg is fully developed, it contains several hundred accessory nuclei that look much like the nucleus except that they don't contain chromosomes. Late in the development of the egg cell, the accessory nuclei disintegrate and centrosomes appear in the same location...

Insects that produce males from unfertilized eggs reveal a surprising cellular feat

Professor Horton continued, "To fully apply this research to improving the productivity of crops we need to understand how these processes relate to plant growth and development in field conditions. Processes that may appear important in the laboratory may not be in the varied conditions...

USC, Rice to develop bacteria-powered fuel cells

...e such bacterium, uses metals instead of oxygen to fully metabolize its food. "Since this organism is capable of passing electrons directly to solid metal oxides, it is not particularly surprising that it can do the same to the anode of the fuel cell, and since we are already in the business of understand...
