Finding that could shed light on "golden staph", candida and allergies
MEDIA RELEASE:
01 Jul 2008
Recent scientific findings explain why people with Hyper IgE Syndrome, or ‘Job’s Syndrome’, are unusually susceptible to certain common infections. By revealing the exact molecular mechanisms involved, they also give us clues as to why some ‘healthy’ people are more prone to these infections than others, and suggest potential treatments.
Silencing of molecular 'conversation' may help curb severe allergies
MEDIA RELEASE:
30 Jun 2008
Scientists in Sydney have identified a process, a synergistic encounter between two molecules, that may account for the extreme allergic reactions some people experience. By silencing at least one of these molecules, it may be possible to treat allergies.
Are the benefits of growth hormone in the athlete's mind?
25 Jun 2008
A new study undertaken by scientists in Garvan's Pituitary Research Unit demonstrates the 'placebo effect' in sport. If athletes believe they are using a performance-enhancing drug, they may think their performance improves, and in some it can, even if they are actually taking a dummy drug.
Garvan cancer researcher wins Premier's Award
18 Jun 2008
Garvan researcher Rebecca Hinshelwood received the highly coveted $10,000 Premier’s Award for Outstanding Cancer Research Scholar at a gala ceremony last month. The award, from the Cancer Institute of NSW, is a form of educational scholarship.
Study shows that prostate cancer increases the risk of bone fracture
MEDIA RELEASE:
14 May 2008
As unlikely as it sounds, scientists at Garvan have shown that there is a link between prostate cancer and a higher risk of bone fracture. Their study suggests that men with prostate cancer face a 50% higher risk of fracture, which increases to nearly 100% if they are receiving androgen deprivation therapy for their prostate cancer.
Genotyping takes us closer to an osteoporosis fingerprint
MEDIA RELEASE:
30 Apr 2008
Garvan collaborated with the Icelandic genetics company, deCode, in an extensive multi-nation genome-wide search to find the genes linked to osteoporosis and fracture. Five regions of interest have been identified that appear to warrant further scientific investigation.
Targeting aggressive breast cancers by putting them to sleep
MEDIA RELEASE:
25 Mar 2008
Dr Alex Swarbrick, head of Garvan's Tumour Progression Research Group, has published findings that Id1, a gene produced by the most aggressive forms of breast cancer, can control breast cancer growth. He has shown that by 'switching off' the Id1 gene, it is possible to induce a state of 'senescence', or permanent sleep, within a tumour, preventing it from growing or spreading.
A tonne of bitter melon produces sweet results for diabetes
MEDIA RELEASE:
22 Mar 2008
Teams from the Garvan Institute of Medical Research and the Shanghai Institute of Materia Medica pulped roughly a tonne of fresh bitter melon and extracted four very promising bioactive components that explain why it is has been used in Chinese medicine for hundreds of years. It now promises to be an effective treatment for Type 2 diabetes.
Low levels of PYY hormone a very early indicator of Type 2 diabetes
MEDIA RELEASE:
10 Mar 2008
Garvan scientists have published findings showing that low levels of the hormone PYY could be used as a predictor for the development of Type 2 diabetes. Clinical studies have shown that people with a family history of Type 2 diabetes, but not yet showing signs of insulin resistance themselves, produce lower levels of PYY after eating, a very early sign of pre-diabetes.
Web-based tool to predict risk of bone fracture
MEDIA RELEASE:
06 Mar 2008
Scientists from Garvan have developed a fracture risk calculator using data, accumulated over 17 years, from the internationally recognised Dubbo Osteoporosis Epidemiology Study. A paper describing the tool and its methodology was published today in the prestigious international journal, Osteoporosis International.
B cell mutations that may cause cancers and autoimmune diseases
MEDIA RELEASE:
29 Feb 2008
To remain healthy, we must maintain exactly the right number of B cells, the white blood cells that produce antibodies. Scientists at Garvan have identified the factors critical to maintaining this important balance within our immune systems. When the balance fails, we become prone to developing certain cancers or autoimmune diseases.
Garvan scientist wins Academy of Science Award
21 Jan 2008
Dr Vanessa Hayes, Head of Garvan's Cancer Genetics Group, has been honoured by the Australian Academy of Science with the inaugural Ruth Stephens Gani Medal for her work in human genetics. The Medal is one of only seven early-career awards issued by the Academy this year to scientists across Australia who are under the age of forty.
Low testosterone in men doubles their risk of bone fracture
MEDIA RELEASE:
15 Jan 2008
Garvan researchers have shown that low levels of testosterone in men double their risk of bone fracture, all other risk factors being equal. This is a significant finding given that 30% of the 110,000 osteoporotic fractures experienced in Australia each year occur in men. It is likely that the findings will have implications for clinical practice, possibly including testosterone supplementation.
Natural gut hormones may provide a treatment for obesity
MEDIA RELEASE:
08 Jan 2008
Garvan researchers have shown that a hormone released naturally from the gut could be used to treat obesity and Type 2 diabetes. After a meal, the hormone peptide YY (PYY) is released from the gut and acts on the brain, contributing to a feeling of satiety. Researchers foresee the use of this hormone as a weight loss medication.
