SYDNEY, Sept. 5 (Xinhua) -- Australian scientists believe " brown fat," a wondrous tissue that burns energy to generate heat, could help people fight obesity, local media reported on Monday.A research team from Sydney's Garvan Institute of Medical Research (GIMR) has worked out how to grow brown fat from stem cells biopsied from adults, raising hopes that one day brown fat could be transplanted in obese people to speed up calories they burn, the Australian Associated Press (AAP) reported.Garvan endocrinologist Paul Lee, who led the research, is optimistic about targeting brown fat as an obesity intervention, commenting "it's a highly metabolically active form of fat, and very exciting that we may be able to stimulate its growth in people."People are born with supplies of brown fat around their neckline to keep them warm as infants, according to scientists at GIMR.Scientists now know that brown fat is present in most, if not all, adults mainly just behind the collarbone.Studies have found that adults with brown fat are slimmer than those without."Although this is early work, it is a proof of concept study showing that the growth of brown fat cells is possible, using precursor cells taken from adult humans, under appropriate stimulation," Lee said."Regardless of whether or not someone has lots of or little brown fat, the precursor cells are universally present. Under the appropriate growth factor and hormonal stimulation, the cells all grow and differentiate into mature brown fat cells."However, Lee warned more work was needed.Lee said even if brown fat was transplanted into obese people or drugs developed to stimulate the growth of brown fat, exercise and a healthy diet would still be crucial to aiding weight loss."So I don't think this is a solution to obesity because there are so many other factors (involved in obesity)," he said."Despite how efficient brown fat is at burning energy, we would only need a few doughnuts to diminish or negate its benefits."Lee said it would be years before tests could be carried out on brown fat transplants.In the meantime, he is expanding his study to test different ways to grow brown fat.His study, to be printed in the October issue of Endocrinology, has been published in the online edition of the journal.

WASHINGTON, June 21 (Xinhua) -- A new study from Harvard School of Public Health (HSPH) and University of California, San Francisco, researchers suggests that men with prostate cancer who smoke increase their risk of prostate cancer recurrence and of dying from the disease. The study will be published Wednesday in the Journal of the American Medical Association."In our study, we found similar results for both prostate cancer recurrence and prostate cancer mortality," said Stacey Kenfield, lead author and a research associate in the HSPH Department of Epidemiology. "These data taken together provide further support that smoking may increase risk of prostate cancer progression."Kenfield and her colleagues conducted a prospective observational study of 5,366 men diagnosed with prostate cancer between 1986 and 2006 in the Health Professionals Follow-Up Study. The researchers documented 1,630 deaths, 524 (32 percent) due to prostate cancer, 416 (26 percent) due to cardiovascular disease, and 878 prostate cancer recurrences.The researchers found that men with prostate cancer who were current smokers had a 61 percent increased risk of dying from prostate cancer, and a 61 percent higher risk of recurrence compared with men who never smoked. Smoking was associated with a more aggressive disease at diagnosis, defined as a higher clinical stage or Gleason grade (a measure of prostate cancer severity). However, among men with non-metastatic disease at diagnosis, current smokers had an 80 percent increased risk of dying from prostate cancer.Compared with current smokers, men with prostate cancer who had quit smoking for 10 or more years, or who had quit for less than 10 years but smoked less than 20 pack-years before diagnosis, had prostate cancer mortality risk similar to men who had never smoked. Men who had quit smoking for less than 10 years and had smoked 20 or more pack-years had risks similar to current smokers."These data are exciting because there are few known ways for a man to reduce his risk of dying from prostate cancer," said senior author Edward Giovannucci, professor of nutrition and epidemiology at HSPH. "For smokers, quitting can impact their risk of dying from prostate cancer. This is another reason to not smoke."Prostate cancer is the most frequently diagnosed form of cancer diagnosed in the United States and the second leading cause of cancer death among U.S. men, affecting one in six men during their lifetime. More than two million men in the U.S. and 16 million men worldwide are prostate cancer survivors.

CANBERRA, Aug. 3 (Xinhua) -- As many as a quarter of Australian women have experienced some form of assault or sexual abuse, and the higher proportion of the abuse, the higher rates of metal illness a woman tends to suffer from, a new study released on Wednesday found.Researchers from the University of Melbourne and the University of New South Wales conducted the study survey of 4451 Australian women aged 16 to 85. It looked at their experience of the four most common types of gender-based violence - sexual assault, rape, stalking and being badly beaten by their partners.About 15 percent of Australian women report sexual assault, while eight percent report rape, 10 percent said they have a stalker and eight percent report being beaten by their partner.It found strong links between those four types of violence and mental health problems including attempted suicide, posttraumatic stress disorder, panic attacks, depression, anxiety, and substance abuse.Among the women who experienced at least one form of violence, 30 percent had a mood disorder, nearly 40 percent an anxiety disorder, 23 percent were abusing substances and 15 percent were affected by posttraumatic stress syndrome.For the women who suffered higher levels of violence, the rates of anxiety disorders was 77 percent, 52 percent for mood disorders, substance abuse 47 percent and posttraumatic stress syndrome 56 percent.More than six percent of women experienced one form of violent had attempted suicide, compared to 35 percent of women who suffered at least three forms of violence.Public health expert Dr Susan Rees from the University of New South Wales' school of psychiatry, who led the research, said she is especially concerned about the suicide rate of women who are abused."What we found was that there's a high association or a strong association between exposure to gender-based violence and all the three broad classes of mental disorder - so that includes mood, anxiety, substance abuse - and a very high association with attempted suicide," she said in the report released on Wednesday."Women who've not experienced gender-based violence have about a 1.6 percent rate of attempted suicide and that increased to six percent of women who had experienced one type of gender-based violence."She said that gender-based violence was also associated with physical disability, impaired quality of life and a worsening of any existing mental disorders.Dr Rees called for the health care system, particularly psychiatric services, to work closer with women's services to improve support for victims of violence.She added that the federal government also need to underscore the importance of getting to the root cause of the violence against women by looking at attitudes towards women and gender inequality.The study was published in the Journal of the American Medical Association.
