Growth Factor Injected

1 Experimental Procedure Aims to Regrow Spinal Disc

Medical trials are being held to evaluate the effectiveness of a new procedure to regenerate spinal disc tissue by injecting chemicals known as growth factors into the damaged disc. According to Michael J. DePalma, M.D., medical director of the VCU Spine Center in Richmond, Virginia, disc injuries are a common source of lower back pain. The trials, involving only a few dozen patients at this point, involve the injection of the growth factor via a needle inserted into the damaged disc under continuous x-ray guidance. The growth factors are similar to naturally produced substances that play a role in producing human cells in the body. After injection the patient's spine is monitored for any changes via x-ray.

No Sun, No Fish, No Vitamin D

2 Rickets Resurgence Among Couch Potato Kids

British doctors are reporting that the once nearly extinct condition of rickets has become "disconcertingly common" among children in that country, according to a study in the current edition of the British Medical Journal. The Victorian disease is easily prevented by exposure to sunlight and consumption of vitamin D-rich foods like fish. But today's youngsters spend so much time indoors in front of a computer or television screen and eat so much vitamin deficient junk food that the disease is making a comeback. In earlier days British children were dosed with foul-tasting cod liver oil to prevent the disease. And adults in Britain are also at risk, with one in six having a severe vitamin D deficiency during the winter and spring.

Shut Up and Drive

3 Study Finds that Driving Impairs Conversation

The results of a new study indicate that driving impairs verbal communication skills. The study, conducted by researchers at the University of Illinois, is the first to conclude that driving hinders conversation, contrary to results from two previous studies. "The previous findings made no sense to those of us who have studied language," said Gary Dell, a psycholinguist in the department of psychology at the U of Illinois. "You might think that talking is an easy thing to do and that comprehending language is easy. But it's not. Speech production and speech comprehension are attention-demanding activities, and so they ought to compete with other tasks that require your attention – like driving."

Blueberries Benefit Elderly

4 Blueberry Juice Improves Memory

Blueberries improve memory, according to new clinical evidence conducted on humans and published in the Journal of Agricultural and Food Chemistry. Previous studies, which had been conducted on laboratory animals suggested that eating blueberries may help boost memory in the elderly. The new study tested the effect of blueberry supplementation on human volunteers in their 70s who exhibited signs of early memory loss. They showed a significant improvement on learning and memory tests after consuming a specific amount of blueberry juice daily. "These preliminary memory findings are encouraging and suggest that consistent supplementation with blueberries may offer an approach to forestall or mitigate neurodegeneration," said the report.
