ESC Press Statement: Balance organs affect brain blood flow
The organs of the inner ear have a direct effect on brain blood flow, independent of blood pressure and CO2 levels in the blood. Researchers writing in the open access journal BMC Neuroscience used a series of human centrifuge experiments to investigate the effects of stimulation of the otoliths and semi-circular canals on cerebrovascular response.
Study reveals 2/3 of prostate cancer patients do not need treatment
In the largest study of its kind, the international team of pathologists studied an initial 4,000 prostate cancer patients over a period of 15 years to further understanding into the natural progression of the disease and how it should be managed. The research, published in the British Journal of Cancer, could be used to develop a blood test to distinguish between aggressive and non-aggressive forms of prostate cancer. more
Ultrasound can predict tumor burden and survival in melanoma patients
Researchers have shown for the first time that patterns of ultrasound signals can be used to identify whether or not cancer has started to spread in melanoma patients, and to what extent. The discovery enables doctors to decide on how much surgery, if any, is required and to predict the patient's probable survival. more
Discovery could improve hepatitis C treatment
Walter and Eliza Hall Institute researchers are part of an international team that has discovered a genetic variation that could identify those people infected with hepatitis C who are most likely to benefit from current treatments. more
Childbearing increases risk of metabolic syndrome
Childbearing is associated directly with future development of the metabolic syndrome — abdominal obesity, high triglycerides, insulin resistance and other cardiovascular disease risk factors — and for women who have had gestational diabetes, the risk is more than twice greater, according to a study co-authored by University of Alabama at Birmingham (UAB) researchers published in the American Journal of Obstetrics and Gynecology.
Rethinking Alzheimer's disease and its treatment targets
The standard explanation for what causes Alzheimer's is known as the amyloid hypothesis, which posits that the disease results from of an accumulation of the peptide amyloid beta, the toxic protein fragments that deposit in the brain and become the sticky plaques that have defined Alzheimer's for more than 100 years. more
