Genetic factor controls health-harming inflammation in obese

CLEVELAND – June 13, 2011 –Researchers at Case Western Reserve University School of Medicine have discovered a genetic factor that can regulate obesity-induced inflammation that contributes to chronic health problems. If they learn to control levels of the factor in defense cells called macrophages, "We have a shot at a novel treatment for obesity and its complications, such as diabetes, heart disease and cancer," said Mukesh K. Jain, MD, Ellery Sedgwick Jr. Chair, director of the Case Cardiovascular Research Institute, professor of medicine at Case Western Reserve University ...

Promising new target for stifling the growth and spread of cancer

Cancer and chronic inflammation are partners in peril, with the latter increasing the likelihood that malignant tumors will develop, grow and spread. Researchers at the University of California, San Diego School of Medicine say they've identified a tumor inflammation trigger that is common to most, if not all, cancers. And using existing inhibitory drugs, the scientists were able to dramatically decrease primary tumor growth in animal studies and, more importantly, halt tumor progression and metastasis. The findings appear in the June 14 issue of the journal Cancer Cell, ...

SACLA laser sets new record

RIKEN and the Japan Synchrotron Radiation Research Institute (JASRI) have successfully produced a beam of X-ray laser light with a wavelength of 1.2 Angstroms, the shortest ever measured. This record-breaking light was created using SACLA, a cutting-edge X-ray Free Electron Laser (XFEL) facility unveiled by RIKEN in February 2011 in Harima, Japan. SACLA (SPring-8 Angstrom Compact free electron LAser) opens a window into the structure of atoms and molecules at a level of detail never seen before. The use of ultra high-intensity X-ray free electron laser light to explore ...

New discovery -- copepods share 'diver's weight belt' technique with whales

A deep-sea mystery has been solved with the discovery that the tiny 3 mm long marine animals, eaten by herring, cod and mackerel, use the same buoyancy control as whales. Reporting this week in the journal Limnology and Oceanography, researchers from British Antarctic Survey describe how Southern Ocean copepods – a crustacean rich in omega-3 oil – 'hibernates' in the deep ocean during winter when seas are stormy and food scarce. To reach the ocean depths the copepod's oily body fluids undergo a remarkable transformation. As the animals swim deeper, water pressure triggers ...

Cancer survivors spend more on health care

Approximately 12 million people in the United States are cancer survivors. On average, their medical care costs $4,000 to $5,000 more annually than the care of people who have never had cancer, according to Penn State researchers. Those who are treated for and survive cancer are susceptible to later health complications and their total medical expenses average about $9,300 per year. People are considered cancer survivors from the moment they are diagnosed through the end of their lives. Advances in medicine enable more people to survive cancer, but there is little information ...
