The power of one: A simpler, cheaper method for cell fusion

...y current method for electrofusion requires a very expensive and specialized electrical pulse generator," said Lu, a professor of agricultural and biological engineering at Purdue University. "My device uses constant DC voltage and would enable researchers to fuse one pair of cells at a time." Electrofusion...

To slow AIDS in Russia, treat HIV-positive addicts, Stanford study says

...edication only to non-drug users was not the most expensive approach, but it prevented the fewest new infections, according to the study. Treating both populations equally provided the most health benefit for the money, said Owens. One key to implementing treatment programs will be keeping injection drug...

Researchers develop technologies to devour food pathogens

..., and is about three times faster and one-tenth as expensive as current technology. A second innovation uses chlorine dioxide gas to kill pathogens on produce, fresh fruits and vegetables. This would be a large step up from current technologies, which mainly involve washing and scrubbing, and cannot complete...

Small, smaller, smallest -- The plight of the vaquita

...o monitor trends is a tricky one. Ship surveys are expensive and they cannot be expected to detect population declines or increases on an acceptable timescale for such a critically endangered species. According to one analysis, a single survey in 2006 or 2007 would have a probability of only 11% of detecting a...

Quantum dots reviewed -- Could these nanoparticles hold the cure to cancer?

Mayo Clinic: Gene expression profiling not quite perfected in predicting lung cancer prognosis

...hnique that does not significantly outperform less expensive and easily conducted approaches is less likely to be useful in clinical practice," the authors wrote. Few studies have compared conventional methods of lung cancer prediction with gene profiling. It remains to be seen whether gene expression profi...

Professors to develop hand-held pathogen testing device

...pathogen on an individual basis is dangerous, more expensive and time consuming. Simultaneous testing simplifies the process, making it safer and more cost effective. Earlier this year, Hashsham was awarded $966,608 from the 21st Century Jobs Fund to develop and commercialize the device. Hashsham, James...

A transplant in time

... exist, may consist of risky blood transfusions or expensive enzyme replacement therapy. But what if the body could be induced to begin producing these proteins, say by transplanting healthy tissue with the abilities that are lacking? Prof. Yair Reisner and Ph.D. student Anna Aronovich of the Weizmann Institu...

Sandia research to focus on early detection of harmful algal blooms

...istic of the blooms are cumbersome, require either expensive reagents or animal testing, or are unable to quantify toxins - critical information for managing shellfish beds. The technologies under development at Sandia would eliminate these problems. "Today's standard detection methods, frankly, are too slow...

Amgen introduces comprehensive financial assistance programs for cancer patients

... medicines. "We recognize that treating cancer is expensive and our industry needs to find new ways to ease the financial burden on cancer patients, their families and society," said Kevin Sharer, chairman and chief executive officer at Amgen. "Our goal is to create the most comprehensive oncology access pro...

New study reveals structure of E. coli multidrug transporter protein

...ise the cost of medical treatment and are far more expensive than treating normal infections. Treating drug-resistant tuberculosis, for example, requires so-called second-line drugs if standard treatment fails. According to the Centers for Disease Control, second-line drugs can cost as much as "$33,000 per pat...

Ten years later, Dolly is still making headlines

...Biopharmaceutical medications are some of the most expensive medicines on the market. Approving generic formulas, therefore, has the potential to put once inaccessible drugs within the reach of millions more people, but at what cost? At the Boston meeting, there will be an Open Forum on Sunday, June 18 from 8 ...

Finding paves way for better treatment of autoimmune disease

...washima says. Isolating them is doable but a long, expensive process. When researchers gave some of the regulatory T cells to a mouse model of inflammatory bowel disease, the symptoms, including dramatic weight loss, went away. Animals showed no classic signs of inflammation, just a significant increase in r...

Sticky surfaces turn slippery with the flip of a molecular light switch
