The research may lead to the development of new drugs or delivery systems to treat cancer by blocking this receptor, known as natriuretic peptide receptor A (NPRA). The findings appeared online recently in the journal Stem Cells. "Our results show that NRPA signaling by cancer cells produces some molecular factors that attract stem cells, which in turn form blood vessels that provide oxygen and nutrients to the tumor," said the study’s principal investigator Subhra Mohapatra, PhD, associate professor in the Department of Molecular Medicine…

For modern, harried lifestyles focused on getting and spending, fitness experts say tai chi, the ancient Chinese slow-moving exercise, can be an ideal way for anyone to stay fit. A staple in senior citizen centers and a common dawn sighting in public parks, the practice can offer long-term benefits for all age groups. “In this high-tech world that's all about speed, greed and instant gratification, tai chi is the antidote to bring us back to balanced health,” according to Arthur Rosenfeld, a tai chi master and the author of a new book called “Tai Chi — The Perfect Exercise: Finding Health, Happiness, Balance, and Strength.” “It doesn't mean you can win the marathon or clean and jerk 750 pounds or win a cycle sprint,” said the South Florida resident, 56. “It's not about getting there sooner.” Tai chi is more about how the body works than how it looks, and is about aging gracefully and “with less drama.” “The last time I looked, there were some 500 studies about the various physical benefits of tai chi, from improving balance and attention span to boosting the immune system to beating back the symptoms of arthritis, asthma and insomnia,” said Rosenfeld. An estimated 2.3 million U.S. adults have done tai chi in the past 12 months, according to a 2007 National Health Interview Survey. The practice is not perfect. Tai chi “does not supply the cardiovascular component that we'd be looking for in a well-rounded routine,” said Jessica Matthews, a San Diego, California-based exercise physiologist. “The exertion level, while challenging, is not going to increase your heart rate.” 'Grand ultimate motion' T'ai chi ch'uan, as it is formally known, derives from a form of Chinese martial arts. Explaining the slow, circular movement of the practice, Rosenfeld said tai chi is a philosophical term that means the harmonious interplay of opposing forces. When nature encounters a strong force, the way it answers that force to maintain harmony in the world is with a spiral, he said. “Astronomers see galaxies moving in spirals, water goes down the drain in a spiral, tornados form as a spiral. We spiral in tai chi because the most effective way to move fluid through solid is a spiral.” Hawaii-based personal and group-fitness trainer Jordan Forth, who has studied tai chi since 2006, said one translation of tai chi is “grand ultimate motion.” “I recommend it to everybody,” said Forth. “It teaches people to move well in multiple planes of motion with a state of awareness not cultivated in everyday fitness. Most people check out on a treadmill or during high-intensity activity.” Forth said tai chi improves mobility, movement and flexibility and can be even more dynamic than yoga, which the 35-year-old has studied since he was a teenager. “With tai chi you're grounded the entire time,” he said. “For me, (it) translates more into functional everyday movement.” Matthews, who is also a spokeswoman for the American Council on Exercise, said because tai chi is slow motion and low impact, many assume it's just for older people or not a viable means of exercise. Not so, she said: Research studies have found that the practice increased mineral bone density, boosted endurance, strengthened the lower body, and eased depression.source : http://www.foxnews.com/health/2013/06/17/tai-chi-getting-there-more-slowly-but-gracefully-and-intact/
Miami police are searching for a Venezuelan doctor who performed butt surgery on a 28-year-old woman – which allegedly led to her death. Suyima Torres was going into surgery for her second round of treatment for gluteus augmentation on April 11 at the Cuerpos Health and Aesthetic Clinic, located on the second floor of a shopping center, the Miami Herald reported.  A friend had recommend the clinic to her. According to the Florida Department of Health, the clinic is only authorized to operate as a massage salon, but the center’s Facebook page claims they employ certified plastic surgeons. Torres received her first treatment at the clinic on April 1, paying the doctor $1,500 in cash. According to her parents, the doctor initially told her she would have to wait a month for the next treatment, but that day he said her inflammation was gone – and Torres could return the next week. Paying $800 in cash for the second treatment, Torres returned alone to the clinic on April 11 at 9 a.m. After the treatment was over, she complained that she felt dizzy, according to Ruth Planas, the clinic’s owner.  Planas called an ambulance, which transported Torres to Doctors Hospital in Coral Gables. Torres was pronounced dead at 9:50 p.m. of a lung embolism, the Miami Herald said. Authorities said they are investigating the death as a homicide in relation to Torres’ surgery.  The identity of the alleged doctor has not been revealed.

The study, "The Ketogenic Diet and Hyperbaric Oxygen Therapy Prolong Survival in Mice with Systemic Metastatic Cancer," was published online today in PLOS ONE. Led by Dominic D’Agostino, PhD, principal investigator in the Department of Molecular Pharmacology and Physiology at the USF Health Morsani College of Medicine, the research shows the effects of combining two nontoxic adjuvant cancer therapies, the ketogenic diet and hyperbaric oxygen therapy, in a mouse model of late-stage, metastatic cancer…
Taking Ritalin and other drugs for attention-deficit/hyperactivity disorder (ADHD) doesn't affect a child's chances of trying or abusing alcohol and drugs later in life, a new review suggests. Researchers pooled data from 15 studies that included a total of 2,600 kids and teenagers with ADHD who were or were not medicated with stimulants and were followed for anywhere from 3 to 28 years. They found no clear difference in how many participants started using or abusing alcohol, cigarettes, marijuana or cocaine, based on how their ADHD was managed. “The scientific evidence suggests that the risk for alcohol and substance problems later in development, in adolescence or adulthood, doesn't seem to be strongly tied to whether or not children were previously… treated with stimulant medication,” said psychologist Steve Lee, who worked on the new study. That means parents should focus on discussing more immediate effects of stimulants with their child's doctor, such as sleep or appetite problems, he added. Kids with ADHD are known to be at higher risk of developing substance problems than those without the disorder. One analysis from 2003 suggested kids treated with stimulants were less likely to develop alcohol and drug problems than their peers with ADHD. Lee and his colleagues from the University of California, Los Angeles, wanted to see how that picture looked once more recent studies were taken into account. The researchers analyzed data related to substance use or abuse of each drug separately. For every category they looked at - alcohol, nicotine, marijuana, cocaine and other drugs - Ritalin and similar stimulants weren't tied to a clear increase or decrease in future use or abuse. That finding isn't the end of the story, the study team said. For example, it's not clear whether the effects of stimulants are different for boys and girls. And because kids in these studies were not randomly assigned to take stimulants or not, it's possible they varied in other ways that may have affected future drug and alcohol use, such as ADHD severity, the researchers write in JAMA Psychiatry. “What I say to parents when I'm talking to them about medication is, the medication is unlikely to have any adverse effects on substance use as far as we know right now,” said William Pelham, head of the Center for Children and Families at Florida International University in Miami, who wasn't involved in the new study. But, he said, “We don't have a lot of studies going into the full range of years when people (are most at risk for) substance abuse.” According to the U.S. Centers for Disease Control and Prevention, parent reports suggest that close to one in 10 kids and teens in the U.S. has ever been diagnosed with ADHD, and two-thirds of those with a current diagnosis are treated with medication such as stimulants. Those drugs can come with short-term side effects, including appetite loss and stomach aches. Because of that, “psychosocial, parent-management types of strategies probably ought to be the first line of treatment,” rather than medication, Lee said. In general, stimulants haven't been shown to have long-term side effects in the years after kids stop taking them, Pelham said - but they also don't seem to have long-term benefits. He agreed with Lee that parents should be looking to non-drug ways to improve the outlook for children with ADHD, including working closely with teachers as kids grow up. And because those youth are at higher risk of drug and alcohol problems due to their ADHD, they should have access to programs to improve decision-making skills and peer relationships, Pelham said.source : http://www.foxnews.com/health/2013/05/30/adhd-medications-not-tied-to-drug-alcohol-abuse/
