Study links progenitor cells to age-related prostate growth: As the organ enlarges, the risk for cancer and other diseases increases

The prostates of older mice contain more luminal progenitor cells — cells capable of generating new prostate tissue — than the prostates of younger mice, UCLA researchers have discovered. The observation, published in Cell Reports, helps explain why, as people age, the prostate tends to grow, leading to an increased risk for prostate cancer and other conditions. “Understanding what’s causing […]

Sheaths drive powerful new artificial muscles

Over the last 15 years, researchers at The University of Texas at Dallas and their international colleagues have invented several types of strong, powerful artificial muscles using materials ranging from high-tech carbon nanotubes (CNTs) to ordinary fishing line. In a new study published July 12 in the journal Science, the researchers describe their latest advance, called sheath-run artificial muscles, or […]

Measuring chromosome imbalance could clarify cancer prognosis: A study of prostate cancer finds ‘aneuploid’ tumors are more likely to be lethal than tumors with normal chromosome numbers

Most human cells have 23 pairs of chromosomes. Any deviation from this number can be fatal for cells, and several genetic disorders, such as Down syndrome, are caused by abnormal numbers of chromosomes. For decades, biologists have also known that cancer cells often have too few or too many copies of some chromosomes, a state known as aneuploidy. In a […]

Growing evidence: Water as a potential treatment for inherited cause of kidney failure

People with polycystic kidney disease (PKD) could benefit from a moderate increase in water intake, according to new research. A study from The Westmead Institute for Medical Research found that a moderate increase in water intake in rats with PKD led to a long-term reduction in kidney cyst growth and fibrosis. This latest findings add to the growing body of […]

Revolutionary technology pinpoints biopsies to detect prostate cancer

Medical software developed at UCL that overlays tumour information from MRI scans onto ultrasound images can help guide surgeons conducting biopsies and improve prostate cancer detection. A team of engineers and medical researchers found that the technology enabled surgeons to pick up clinically relevant cancers that were missed when using current visual detection methods. The best approach would be to […]
