Posted: 07 Feb 2012 10:37 AM PST In a study of nearly 200 clinically obese, non-diabetic adults, a researcher found that a 600-calorie breakfast that includes dessert as well as proteins and carbohydrates can help dieters lose weight and keep it off over the long term. Her research indicates that such a morning meal staves off cravings and defuses psychological addictions to sweet foods.

Vitamin D deficiency high among trauma patients Posted: 07 Feb 2012 10:37 AM PST New research has found that 77 percent of trauma patients had deficient or insufficient levels of vitamin D.

Knee replacement may lower a patient's risk for mortality and heart failure, study suggests Posted: 07 Feb 2012 10:36 AM PST New research highlights the benefits of total knee replacement.

Competitive soccer linked to increased injuries and menstrual dysfunction in girls Posted: 07 Feb 2012 10:36 AM PST In the US, there are nearly three million youth soccer players, and half of them are female. New research has found that despite reporting appropriate body perception and attitudes toward eating, elite youth soccer athletes face an increased risk for delayed or irregular menstruation.

As Valentine's day approaches, cardiologist describes broken heart syndrome Posted: 07 Feb 2012 09:19 AM PST People who have been unlucky in love are said to suffer from a "broken heart." A broken heart is an actual medical condition. Broken heart syndrome occurs during highly stressful or emotional times, such as a painful breakup, the death of a spouse or the loss of a job.

First remote-control leg lengthening implant cleared by the FDA Posted: 07 Feb 2012 09:19 AM PST A revolutionary new limb lengthening system developed by orthopedic surgeons represents a major advancement in the treatment of limb deformities.

New non-invasive fat removal technologies offer alternative to liposuction for removing stubborn fat Posted: 07 Feb 2012 09:18 AM PST Dermatologists are finding that the introduction of non-invasive fat removal technologies is opening the door for more people who are not candidates for liposuction to remove stubborn fat, safely and effectively.

Lasers lighting the way for enhanced treatment of melasma and tattoo removal Posted: 07 Feb 2012 09:18 AM PST On the surface, it would seem as though the skin condition melasma and tattoos would have little in common. However, they both affect a person's skin, can be quite difficult to treat or remove and, now, dermatologists are discovering new laser therapies which enhance treatment for both conditions.

New anti-aging treatments make it easier to turn back the clock Posted: 07 Feb 2012 09:18 AM PST As we age, our skin undergoes a number of changes affecting its texture, volume and appearance. Fortunately, dermatologists can use fillers or lasers to correct the most notable signs of aging and can recommend skin care products with added ingredients that can further repair damaged skin.

Study of live human neurons reveals Parkinson's origins Posted: 07 Feb 2012 09:18 AM PST Parkinson's disease researchers have discovered how mutations in the parkin gene cause the disease, which afflicts at least 500,000 Americans and for which there is no cure.

Why bad immunity genes survive: Study implicates arms race between genes and germs Posted: 07 Feb 2012 09:18 AM PST Biologists have found new evidence for why mice, people and other vertebrate animals carry thousands of varieties of genes to make immune-system proteins named MHCs -- even though some of those genes make us sick.

The dark path to antisocial personality disorder Posted: 07 Feb 2012 07:00 AM PST With no lab tests to guide the clinician, psychiatric diagnostics is challenging and controversial. Antisocial personality disorder is defined as "a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood," according to a standard definition. But, until now, no one has studied the dimensional structure associated with the DSM antisocial personality disorder criteria.

Why the middle finger has such a slow connection Posted: 07 Feb 2012 07:00 AM PST Each part of the body has its own nerve cell area in the brain -- we therefore have a map of our bodies in our heads. The functional significance of these maps is largely unclear. What effects they can have is now shown by neuroscientists through reaction time measurements combined with learning experiments and "computational modeling." They have been able to demonstrate that inhibitory influences of neighboring "finger nerve cells" affect the reaction time of a finger.
