Discovery Opens The Door To A Potential 'Molecular Fountain Of Youth'
2/05/2013
A new study led by researchers at the University of California, Berkeley, represents a major advance in the understanding of the molecular mechanisms behind aging while providing new hope for the development of targeted treatments for age-related degenerative diseases...
Experimental Therapy Crosses Blood-Brain Barrier To Treat Neurological Disease
2/04/2013
Researchers have overcome a major challenge to treating brain diseases by engineering an experimental molecular therapy that crosses the blood-brain barrier to reverse neurological lysosomal storage disease in mice. Posted online in PNAS Early Edition on Feb. 4, the study was led by scientists at Cincinnati Children's Hospital Medical Center...
Cuba - Investing In Biotechnology To Battle Cancer
2/04/2013
The Cuban government has made a substantial investment in biotechnology in a drive to battle cancer, the country's second leading cause of death, after cardiovascular disease. The World Health Organization (WHO) estimates that 31,000 new cancer diagnoses are made in Cuba each year, and that 21,000 patients die of the disease annually...
A research team in Japan exploring the functions of messenger ribonucleic acid (mRNA) - a molecule that encodes the chemical blueprint for protein synthesis - has discovered a way to take a close look at the temperature distribution inside living cells. This discovery may lead to a better understanding of diseases, such as cancer, which generate extraordinary intracellular heat...
Human Cells Probed With High-Frequency Sound
2/04/2013
Sound waves are widely used in medical imaging, such as when doctors take an ultrasound of a developing fetus. Now scientists have developed a way to use sound to probe tissue on a much tinier scale. Researchers from the University of Bordeaux in France deployed high-frequency sound waves to test the stiffness and viscosity of the nuclei of individual human cells...
Differences In Tissue Stiffness Have Potential To Aid In Diagnosis, Therapy Of Breast Cancer
2/04/2013
The texture of breast cancer tissue differs from that of healthy tissue. Using a cutting-edge tissue diagnostic device, a group of researchers in Basel, Switzerland, has determined one key difference: cancerous tissue is a mix of stiff and soft zones, whereas healthy tissue has uniform stiffness...
The shortened daylight of a Maine winter may make for long, dark nights - but it has shone a light on a novel experimental approach to fighting inflammatory breast cancer (IBC), an especially deadly form of breast cancer. The new approach enlists the active form of Vitamin D3, called calcitriol, which is delivered therapeutically by quantum dots...
A New Mechanism That Contributes To The Evolution Of Cancer
2/04/2013
This study, which involves the participation of CNIO researcher Oscar Fernandez-Capetillo, demonstrates the existence of new fragile genomic sites responsible for chromosomal alterations in tumors Cancer arises from the accumulation of mutations and structural changes in chromosomes, which in some cases give rise to combinations that favour the growth or expansion of the disease...
Blood In Your Urine - Don't Just Ignore It
2/04/2013
Many people are still not seeking medical advice soon enough when they see blood in their urine, even though almost 1 in 5 will have a urinary tract malignancy[1]. Action on Bladder Cancer (ABC), the only UK charity dedicated purely to bladder cancer, calls for urgent awareness - even one episode of visible blood in the urine is a warning sign that should not be ignored[1]...
Time Spent Watching Television Is Not Associated With Death Among Breast Cancer Survivors
2/04/2013
Spending a lot of time watching television after breast cancer diagnosis is not linked to death in these breast cancer survivors. It appears that after accounting for self-reported physical activity levels after diagnosis, sedentary behavior was not an independent risk factor for death...
