How brain pacemakers erase diseased messages

Brain "pacemakers" that have helped ease symptoms in people with Parkinson's disease and other movement disorders seem to work by drowning out the electrical signals of their diseased brains. Despite the clinical success of the devices, which have been approved by the Food and Drug Adminis...

Percutaneous aortic valve replacement safe, successful in high-risk patients

...nutes to minimize blood flow through the aorta and ease placement of the replacement valve. All 17 patients survived the procedure. One patient died 5 days later from stroke. Five additional patients died after discharge from the hospital from health problems unrelated to the replacement valve. Follow...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

...maximum of 100 micrograms per litre. Due to the ease of use of this sensor and its portability, the technique can be used in situ for quantitative analysis of the presence of atrazine, as well as that of other herbicides, in food and water samples outside the laboratory. The sensor can be easily prepa...

Type of stem cell found to reside in transplanted lungs

.... The ability to isolate these cells with relative ease from lavage fluid is a very significant finding as it provides a potential source to isolate MSCs, says Victor J. Thannickal, M.D., associate professor of Internal Medicine in the Division of Pulmonary and Critical Care Medicine and senior author on ...

Researchers discover new details about HIV-1 entry and infection

...ract is key to prevent infection and ultimately to ease the pandemic." Dr. Florian Hladik and colleagues in the McElrath laboratory developed a unique model system to study the precise mechanisms by which HIV-1 enters the lower reproductive tract of human females. The researchers separated and removed...

Tissue engineering for craniofacial reconstruction

New imaging technique tracks traffic patterns of white blood cells

..., a subset of inflammatory white blood cells. "The ease and rapidity of this method, and the abilty to combine it with current genetic labeling techniques will greatly aid investigations to elucidate in vivo imflammatory cell behavior, and provide a powerful tool for the development of therapeutics for th...

Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal

... rejection. "This therapy has the potential to ease the pressure on the waiting list while also offering patients a better alternative to a donor heart ?their own, healthy heart," she added. Professor Sir Magdi Yacoub, from the Heart Science Centre at Imperial and the Royal Brompton and Harefield...

Tarantula venom and chili peppers target same pain sensor

...nsing neurons work, and to help develop drugs that ease persistent pain, the scientists report. Their finding, based on studies of mice cells in culture and live mice, is published in the November 9 issue of the journal Nature. The senior author is David Julius, professor and chair of physiology at UCSF. ...

New technology to speed up research into Huntington's disease

... reluctant to engage with such research. Given the ease of use of the touch screen system, it is hoped this will change. Dr Jenny Morton, Dr Lisa Saksida and Dr Tim Bussey from the Departments of Pharmacology and Experimental Psychology at the University of Cambridge, who led the research, tested norma...

Beauty and the brain

...nificant, Winkielman said, is that when processing ease was controlled ?when, that is, the categorization speed was factored out of the equation ?much of the relationship between closeness to prototype and attractiveness disappeared. A third experiment ?again with abstract, random-dot images ?was perfo...

Tamed 11,400 years ago, figs were likely first domesticated crop

... Bar-Yosef, Kislev, and Hartmann suggest that this ease of planting, along with improved taste resulting from minor mutations, may explain why figs were domesticated some five millennia before other fruit trees, such as the grape, olive, and date. "The reported Gilgal figs, stored together with other veg...

Amgen introduces comprehensive financial assistance programs for cancer patients

No-mow grass may be coming to your yard soon

... cities, and berry bushes could be made taller for ease of harvesting. To chart the pathway, Chory and colleague Grégory Vert of the Salk Institute's Plant Biology Laboratory examined the molecular influence of a family of plant hormones known as brassinosteroids. Scientists have found brassinosteroids ...

Origen publishes in Nature a robust and versatile method for creating transgenic chickens

... their eggs. The use of primordial germ cells, the ease of producing small or large flocks of chickens, and the existing infrastructure for rearing chickens and processing eggs means that therapeutic proteins can now be produced efficiently and economically in the eggs of chickens." Origen scientists fir...

MUHC announces a transplant first in Quebec
