First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...g surgery, chemotherapy, or radiation to excise or shrink the primary tumor. "However, in too many cases it's simply impossible to completely remove the tumor," Dr. Huang explained. "So recently the idea of targeting cell migration -- metastasis -- has become an alternative strategy that's gained a lot of ...

New Treatment Rivals Chemotherapy For Lymphoma, Study Finds

...motherapy with fewer side effects caused tumors to shrink in 95 percent of patients, a new study by researchers at the University of Michigan Comprehensive Cancer Center found. Patients with advanced-stage follicular lymphoma ?a cancer generally considered incurable ?who had not been previously treated wit...

Scientists find fossil proof of Egypt's ancient climate

... years. "Strong evaporation of the lake, enough to shrink it substantially in volume and make it more saline would have been expected to result in large excursions in d18O and minor element concentrations," Kieniewicz said. "However, throughout the stratigraphy, the d18O values of the silts remain isotopica...

Potential treatments for neurofibromatosis

...th continuing treatment, they hope the tumors will shrink or die from lack of blood vessel support. Neurofibromatosis gets its name from neurofibromas, the disfiguring and often painful tumors that grow along nerve coverings and form on or under the skin. In most patients, the tumors begin to appear in ado...

New tumor-suppressor gene discovered

...wts gene. "We found that mats and wts together can shrink the fly's eye much more dramatically," Lai reports. "Their effect is not additive, but synergistic. The two genes have a more powerful effect when they combine to work together in reducing cell proliferation and promoting cell death, so the tissues g...

Microscopes at microscopic size

An interdisciplinary research team, funded by the Biotechnology and Biological Science Research Council (BBSRC) and the Engineering and Physical Sciences Research Council (EPSRC) have develope...

Mice brains shrink during winter, impairing some learning and memory

The brains of one species of mouse actually shrink during the winter, causing the mice to have more difficulty with some types of learning, a new study found. The results showed that, during the short days of winter, white-footed mice had impaired spatial memory ?the mental map that helps them remem...

Sudden change in social status triggers genetic response in male fish, study finds

...tious colors and stripes disappear, and the testes shrink and the male becomes infertile. "Previously we did an experiment in which we moved the subordinate male out of the tank and put him in a situation where he could rise and become dominant," Fernald says. "Because he was in a new situation, it too...

New battery technology helps stimulate nerves

...ng on line as scientists and engineers continue to shrink the components that make up the devices. Central to that ability, according to University of Wisconsin-Madison Professor Emeritus of chemistry Robert West, is new lithium battery technology, technology capable of making batteries smaller, last longe...

New University of Toronto research a 'pore' excuse for engineering

...ould take up far less room, allowing components to shrink even further. "Industry is always looking for a better insulator," Hatton says. "This is an example of how materials chemistry can provide innovative solutions to the design of novel materials." ...

...ells, telomerase is shut off, and telomeres slowly shrink during cell division ?a normal process that helps limit cells' lifespan. Cancer cells, however, usually find a way to turn telomerase back on, achieving a dangerous immortality. "Getting telomeres replicated again is required for carcinogenesis to ...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...e cell into an electron microscope, and it doesn't shrink when air is evacuated from the microscope chamber." The cell can be immediately imaged, says Brinker. "Spin-coating" refers to deposition of the cell slurry on a spinning substrate until dry. From their comfortable "home," the empowered cells can...

Scientists discover why cornea is transparent and free of blood vessels, allowing vision

'Pinball protons' created by ultraviolet rays and other causes can lead to DNA damage

...eakthrough would allow small electronic devices to shrink even further, but how the electrical properties of DNA would work in such a context is not yet understood. The UGA research adds important knowledge about how so-called "deprotonated" DNA base pairs work and could be important in creating "DNA wire."...

Surprise finding for stretched DNA

...h the radius of the DNA double-helix is allowed to shrink as the molecule is stretched. The model consists of an elastic rod that is wrapped around its outer surface by a stiff wire, analogous to DNA's sugar-phosphate backbone. The elastic rod is constructed from a material that conserves volume under str...

Researchers to develop ultra-miniature implantable sensors to measure blood flow

... in width, and with development, these sizes could shrink to several microns. To give that size some perspective, the average human hair ranges from 40 microns to 120 microns in diameter. The advantage of such tiny, implanted sensors is that they can provide separate readings for particular organs in a pati...
