Gut research yields new anti-cancer approach

...h drugs would be toxic, destroying microtubules in healthy cells as well as cancer cells," Schaefer said. "Our early studies, however, suggest that general toxicity does not rule out this approach as once feared. With new drug delivery technologies that help drugs target only cancer cells, we are very excite...

Red flag for repetitive stress injuries identified for first time in humans

...s, and other wrist and shoulder injuries, and nine healthy subjects. After a physical examination that rated the severity of symptoms ranging from pain to range of motion, participants were given blood tests for evidence of biomarkers. "The blood tests revealed significant levels of several types of infl...

UC Davis researchers use heated nanoprobes to destroy breast cancer cells in mice

... growth of tumors -- without damage to surrounding healthy tissue. The researchers describe their work in the March issue of the Journal of Nuclear Medicine. "We have demonstrated that the system is feasible in laboratory mice. The next step will be clinical testing in patients," said Sally DeNardo, a profe...

Power-boosting signal in muscle declines with age

...in comparison to 20-year-old adults, even lean and healthy people in their seventies show a higher incidence of fat buildup in their muscle and livers and a deficiency in mitochondrial function, Shulman explained. These metabolic shifts have been implicated in the increased prevalence of insulin resistance a...

Tropical forests -- Earth's air conditioner

...re very efficient at keeping the Earth at a happy, healthy temperature. The researchers, including Ken Caldeira of Carnegie’s Department of Global Ecology and Govindasamy Bala at Lawrence Livermore National Laboratory, found that because tropical forests store large amounts of carbon and produce reflective ...

Nanotextured implant materials: blending in, not fighting back

...s, as opposed to killing off bad cells." Normal healthy blood vessels have a thin lining of specialized cells called the endothelium, surrounded by a thicker layer of smooth muscle cells that make up the arterial wall. The proteins collagen and elastin make up much of this lining and create a texture of f...

Researchers identify ovarian cancer biomarkers

...mors were not expressed by normal ovaries or other healthy organs. The researchers also found these markers were not present in normal reproductive tissues that experience blood vessel growth, such as the placenta or endometrium. This suggests that the markers are specific to tumors and would not be mistaken...

Veterinary scientists explore poultry virus as cancer killer

...clusively in cancerous prostate cells. Normal, healthy cells have an interferon antiviral system that activates upon infection with NDV thereby preventing replication of the virus, explains Dr. Subbiah. Cancer cells, however, have defective interferon antiviral systems, he said. NDV utilizes the defects ...

Bypassing eggs, flu vaccine grown in insect cells shows promise

...ars. In the study funded by the company of 460 healthy people ages 18 to 49, one-third of the participants received a smaller dose of the vaccine (75 micrograms), one-third received a larger dose (135 micrograms), and one-third received a placebo shot that didn’t include vaccine. Each of the “real?shots ...

Detailed spatial analyses of gray matter distribution were conducted by measuring local volumes of gray matter at thousands of locations in the brain. While the brains of lithium-treated bipolar patients did not differ from those...

Robotic exoskeleton replaces muscle work

...The ankle exoskeleton developed at U-M was worn by healthy subjects to measure how the device affected ankle function. The U-M team has no plans to build a commercial exoskeleton, but their results suggest promising applications for rehabilitation and physical therapy, and a similar approach could be used by...
