Research says boiling broccoli ruins its anti-cancer properties

...se significant loss of glucosinolates up to 33% by fracture of vegetable material during thawing. The researchers found that preparation of Brassica vegetables had caused only minor reductions in glucosinolate except when they were shredded finely which showed a marked decline of glucosinolate levels with ...

The effects of smoking on fractures and ligament injuries

... toxins contained in cigarette smoke can undermine fracture and ligament repair following injury. In addition, smokers have higher rates of hip fracture, fracture healing problems and bone infections and smoking has been shown to impair soft tissue wound healing....

...t both are occurring in normal healthy bone during fracture healing" He said by combining the two stimulants, a synergistic effect was produced. "That means when you apply both the mechanical and electrical stimulants together a result greater than the sum of the two stimulants applied individually is a...

Radiologists attempt to solve mystery of Tut's demise

...s. The researchers discovered a possible premortem fracture to the femoral (thigh) bone. While they cannot assess how the injury occurred, the findings suggest that the injury may have been an open wound that became infected and ultimately fatal. Since King Tut was first examined by x-ray in 1968, revealin...

One therapeutic dose of radiation causes 30 percent spongy bone loss in mice

...ervical and colorectal cancer increased their bone fracture risk by 60%. Radiation following anal cancer increased the risk of fracture by 200%, he said. Astronauts lose 2% of bone mass for each month they are exposed to the effects o...

Research identifies protein in mice that regulates bone formation

...ences. One-fifth of patients with osteoporosis who fracture their hips will die within a year. As the baby boomer generation gets older, it is predicted that the number of hip fractures may triple by 2020 unless better prevention and treatment for the disease is improved. The researchers, led by Dallas Jone...

Secrets of the sea yield stronger artificial bone

...between the layers, which are believed to increase fracture resistance. "These characteristics contribute to the scaffolding's mechanical toughness. Cracks don't propagate as easily and more energy is needed to break the material," says Tomsia. "This makes the scaffolding four times stronger than the porous ...
