Zebrafish help decode link between calcium deficiency, colon cancer

By studying zebrafish embryo skin, University of Michigan researchers decoded cell messages underlying abnormal colonic cell growth of the kind that can lead to tumors and colon cancer in calcium deficient individuals. They have also tested this new mechanism in human colon cancer cells. Ultimately, the new biological mechanism unraveled in zebrafish will help scientists understand the pathways that fuel low calcium-related abnormal colonic cell growth and how to stop that growth, said Cunming Duan, professor in the U-M Department of Molecular, Cellular & Developmental Biology. To do this, Duan and colleagues used a fluorescent protein to mark a type of epithelial cell, whose job it is to import calcium into the body. …

First step of metastasis halted in mice with breast cancer

"Metastasis is what most threatens breast cancer patients, and we have found a way to stop the first part of the process in mice," says Andrew Ewald, Ph.D., assistant professor of cell biology at the Johns Hopkins School of Medicine. Before metastasis occurs, single cells on the edge of a tumor, termed leader cells, form protrusions into the surrounding tissue, like someone dipping a toe in to test the water before deciding to venture farther, Ewald says. If the conditions are right, the leader cells act as guides, with many tumor cells following behind, as they escape the confines of the tumor into the healthy tissue beyond. Full metastasis occurs when the cells succeed in migrating to a new location — the lungs, for example — and set up shop, creating a new tumor…

The dirt on hotel rooms

We asked several industry insiders to help us peel back the covers on your home away from home. Here's how to make the most of any stay.  “Eco-Friendly” Actually Means “Dirty Sheets” Here's a travel tip you might not have heard: Bedspreads are often cleaned just once a month. But sheets can dodge detergent, too.  “Some hotels take a unique approach to the water-conservation trend,” the housekeeping director we interviewed said. “Unless they look soiled, sheets may not be changed.” The solution: Ask for fresh sheets.  “When I travel, I change my own sheets,” one hotel director said.  Know what else you should change while you're on the road? Your diet. (Find out how one Men's Health reader wedged tough workouts and smart dining into his busy schedule.) Your Bill is Bogus The average business traveler is overcharged $11.35 a night, according to an audit of hotel bills by Corporate Lodging Consultants, a firm that helps companies and governments trim travel costs. Beware of fees for fridges, or anything labeled “local.” The solution: Question every charge, especially at the end of the month, one hotel controller said.  “It's unbelievable what managers do to make budget.” Even worse than the managers are some of the offerings at the morning buffet. (Avoid these 8 killer breakfast foods.) Upgrades Can Come Cheap Here's a travel tip from insiders: Upgrade at check-in. Full occupancy is rare - the average is 63 percent, according to the American Hotel and Lodging Association, and suites are often vacant.  “A smart manager knows that the cost to clean a suite is roughly the same as for a regular room,” one manager said. The solution: Make the hotel more money. Offer 20 percent more than your current rate for the upgrade; you could be sleeping in a suite. (Just make sure you're sleeping in style with this well-traveled wardrobe.) Some Souvenirs Have Legs Hotels are a haven for bedbugs. Pest-control companies say hotels account for more than 37 percent of their bedbug business, according to Pest Control Technology magazine. The solution: Search for your hotel on bedbugregistry.com. Scan mattress and couch creases for the reddish brown bloodsuckers and their black droppings, Jason Rasgon, a public-health professor at Johns Hopkins, said. At home, dry your clothes on high for 45 minutes to kill stowaways. The Bathroom is Cleaner Than the TV Remote  Often, the worst germ incubators are the frequently touched surfaces: the thermostat dial, phone, and remote. Chuck Gerba, a professor of microbiology at the University of Arizona, actually found more traces of fecal matter on these surfaces than in the bathroom. The solution: Use hand sanitizer, and wash your hands frequently. A recent study reported that cold germs linger for more than a day on surfaces.source : http://www.foxnews.com/health/2013/06/03/dirt-on-hotel-rooms/
