Cutting Fat and Calories Can Lower Cancer Risk in Dogs and People

As many as 1 out of 3 cancer deaths in both humans and dogs could be prevented by reducing Omega-6 fatty acids and cutting calories, according to research presented at the 2010 Institute of Food Technologists (IFT) Annual Meeting & Food Expo®.

Demian Dressler, DVM, known as the “dog cancer vet” because of his work in the study of canine cancer, recommends severely limiting snack foods for humans and dogs that contain ingredients rich in Omega-6, such as corn oil, vegetable oil and grain-fed red meat. Too much Omega-6 fatty acid can lead to inflammation, which creates an environment conducive to cancer in dogs and people, he said.

In addition, Dressler said studies show obesity in both dogs and humans limits the production of adiponectin, a hormone that has been shown to inhibit cancer cell growth. He recommended reducing calories, particularly those from sugar, which has the additional danger of not only causing obesity, but also feeding cancer cells and encouraging their growth.

In comparing human and canine cancer, Dressler bases his research on evidence that dogs have similar cancers to humans, and veterinary oncology uses almost all the human cancer drugs to treat dogs. A dog’s compressed lifespan allows researchers to see effects of the drugs quickly and apply those findings to humans.

The panel encouraged pet food manufacturers to consider the health implications of their products to maximize the animal’s health. Kelly S. Swanson, associate professor in the Department of Animal Sciences at the University of Illinois at Urbana-Champaign, suggested the ideal blend of fiber for dog food is about 75 to 80 percent insoluble and 20 to 25 percent soluble. In addition, adding quality prebiotics to pet foods can enhance their gut health, he said, although research still is needed to determine how much is appropriate for an individual breed.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
