Researchers are reporting that they have developed a “self-fitting” material that expands with warm salt water to precisely fill bone defects that occur as a result of injury, birth defect or surgery to remove a tumor.
Oncologists are melding magnetic resonance imaging (MRI) technology with a traditional ultrasound prostate exam to create a three-dimensional map of the prostate that allows physicians to view growths that were previously undetectable.
A leading physician in Sierra Leone's fight against Ebola has died from the disease, an official said Wednesday, as it emerged that another top doctor had been considered to receive an experimental drug but did not get it and later died.
Faced with tougher and more resistant weeds, corn and soybean farmers are anxiously awaiting government decisions on a new version of a popular herbicide — and on genetically modified seeds to grow crops designed to resist it. Critics say more study is needed on the effects of the herbicide and...
Canada is donating an experimental Ebola vaccine after the World Health Organization declared it is ethical to use untested drugs and vaccines in the ongoing Ebola outbreak in West Africa. Health Minister Rona Ambrose said Tuesday that Canada will donate 800 to 1,000 doses to the World Health...
Federal health regulators have approved a novel device that can preserve donated lungs outside the body for possible transplantation into critically ill patients. The Food and Drug Administration said Tuesday that the approval of the XVIVO Perfusion System could lead to more successful...
The World Health Organization declared it's ethical to use untested drugs and vaccines in the ongoing Ebola outbreak in West Africa although the tiny supply of one experimental treatment has been depleted and it could be many months until more is available. The last of the drug is on its way to...
The Perfecta3D Cell Viability Kit, from 3D Biomatrix and Cayman Chemical, is a new assay kit for measuring the viability of 3-D spheroids and one of the first viability assays optimized for 3-D cell culture.
Researchers at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified a gene that contributes to the development of several childhood cancers, in a study conducted with mice designed to model the cancers. If the findings prove to be applicable to humans, the research could lead to new strategies for targeting certain childhood cancers at a molecular level.
Researchers from The University of Texas at Austin and five other institutions have created a molecule that can cause cancer cells to self-destruct by ferrying sodium and chloride ions into the cancer cells. These synthetic ion transporters confirm a two-decades-old hypothesis that could point the way to new anticancer drugs while also benefiting patients with cystic fibrosis.
Plasmodium falciparum, the parasite that causes malaria, has proven notoriously resistant to scientists’ efforts to study its genetics. It can take up to a year to determine the function of a single gene, which has slowed efforts to develop new, more targeted drugs and vaccines.
Dangerous brain tumors hijack the brain’s existing blood supply throughout their progression, by growing only within narrow potential spaces between and along the brain’s thousands of small blood vessels, new research shows for the first time.
Blood expression levels of genes targeted by the stress hormones called glucocorticoids could be a physical measure, or biomarker, of risk for developing Post-Traumatic Stress Disorder (PTSD), according to a new study.
A gene discovery brings scientists closer to developing therapeutic agents that could slow down bone loss and regenerate lost bone, which could provide relief for millions suffering from aging-related bone loss.
Playing with the portions of good and not-so-good-for-you foods is better than trying to eliminate bad foods, according to a new study. The idea is to not give up entirely foods that provide pleasure but aren’t nutritious.
