The St. Jude Children’s Research Hospital-Washington University Pediatric Cancer Genome Project has identified the most common genetic alteration ever reported in the brain tumor ependymoma and evidence that the alteration drives tumor development. The results provide a foundation for new research to improve diagnosis and treatment of ependymoma, the third most common brain tumor in children.
National Institutes of Health researchers have identified gene variants that cause a rare syndrome of sporadic fevers, skin rashes and recurring strokes, beginning early in childhood. The team’s discovery coincides with findings by an Israeli research group that identified an overlapping set of variants of the same gene in patients with a similar type of blood vessel inflammation.
Scientists discovered that iron deficiency may increase stroke risk by making the blood more sticky. The findings could ultimately help with stroke prevention. The team found that iron deficiency increases the stickiness of platelets, which initiate blood clotting when they stick together. Although a link between iron deficiency and sticky platelets was first discovered almost 40 years ago, its role has been overlooked until now.
Research at the University of Liverpool has explained how cells behave when placed in a low oxygen environment, a development that could have implications for cancer patients and other serious illnesses. The research opens up the possibility of controlling the signals that keep cells alive, preventing the damages caused by ischemia—a restriction of blood supply to tissues. It could also work to help destroy cancer cells.
A new bioprinting method creates intricately patterned 3D tissue constructs with multiple types of cells and tiny blood vessels. The work represents a major step toward a longstanding goal of tissue engineers: creating human tissue constructs realistic enough to test drug safety and effectiveness.
The angiogenesis inhibitor bevacizumab (Avastin) failed to increase overall survival (OS) or statistically significant progression-free survival (PFS) for glioblastoma patients in the frontline setting, according to a study led by researchers at The University of Texas MD Anderson Cancer Center.
Advaxis Inc., a biotechnology company specializing in cancer immunotherapies, announced it has expanded its relationship with the GRU Cancer Center by entering into a master clinical trial agreement. Under the terms of the agreement, the Cancer Center will conduct four Phase 1/2 clinical trials under the supervision of Cancer Center Director Dr. Samir N. Khleif. The planned trials will further develop Advaxis’ two lead immunotherapies: ADXS-HPV for cervical cancer and ADXS-cHER2 for breast cancer. “The preclinical success we have had with the Advaxis platform technology has prompted...
Show more patience in the delivery room: That's the prescription being given to the nation's obstetricians. New guidelines say doctors should give otherwise healthy women more time to deliver their babies vaginally before assuming that labor has stalled. The recommendations are the latest in...
Jazz musicians are famous for their musical conversations — one improvises a few bars and another plays an answer. Now research shows some of the brain's language regions enable that musical back-and-forth much like a spoken conversation. It gives new meaning to the idea of music as a universal language.
The mice in Scott Delp's lab, unlike their human counterparts, can get pain relief from the glow of a yellow light. Right now these mice are helping scientists to study pain—how and why it occurs and why some people feel it so intensely without any obvious injury. But Delp, a professor of bioengineering and mechanical engineering, hopes one day the work he does with these mice could also help people who are in chronic, debilitating pain.
Clemson University researchers have developed nanoparticles that can deliver drugs targeting damaged arteries, a non-invasive method to fight heart disease. One of the standard ways to treat clogged and damaged arteries currently is to implant vascular stents, which hold the vessels open and release such drugs as paclitaxel. The researchers hope their advanced nanoparticles could be used alongside stents or in lieu of them.
Binge drinking impairs the healing of broken bones. It can do this weeks after a binge. And it can leave in its wake permanently inferior bone, according to recent studies. One reason: alcohol slows down mesenchymal (bone, fat, and cartilage) stem cells (MSCs), in the bloodstream, trying to home to fracture sites. And when MSCs finally reach fracture sites, alcohol keeps them from properly replacing lost cells.
ASU scientists, along with colleagues at Argonne National Laboratory, have reported advances toward perfecting a functional artificial leaf. Designing an artificial leaf that uses solar energy to convert water cheaply and efficiently into hydrogen and oxygen is one of the goals of BISfuel—the Energy Frontier Research Center.
The IOC will consider setting up an independent body that allows whistleblowers to report information on doping, match-fixing and sexual abuse without fear of reprisals. Swiss member Denis Oswald made the proposal during a debate on "protecting clean athletes."
The Thermo Scientific Heracell i CO2 incubator features variable oxygen control. Ideal for advanced applications in the area of stem cell research, regenerative and personalized medicine and other protocols that necessitate reduced oxygen concentrations, the incubator models are also available for hypoxic experimentation where oxygen levels above atmospheric levels are required.
