Scoliosis patients get a preview of spinal fusion surgery
“Patients are more at ease when they know what to expect,” says, Dr. Daniel Hedequist, chief of the Spine Division in the Department of Orthopedic Surgery. Dr. Hedequist performs dozens of spinal fusion surgeries each year to treat children with scoliosis. While the procedure is familiar ground for the surgical team at Boston Children’s Hospital, ...

Creating custom brains from the ground up
Scientists studying how genetics impact brain disease have long sought a better experimental model. Cultures of genetically-modified cell lines can reveal some clues to how certain genes influence the development of psychiatric disorders and brain cancers. But such models cannot offer the true-to-form look at brain function that can be provided by genetically-modified mice. Even ... Read More about Creating custom brains from the ground up
A perfect genetic hit: New gene mutation implicated in rare congenital diarrhea
When the 1-year-old boy arrived from overseas, he was relying on total parenteral nutrition — a way of bypassing the digestive system to provide nutrients and calories completely intravenously — to survive. From the time of his birth, he had experienced unexplainable diarrhea. Answers were desperately needed. Sequencing his genes in search of clues, neonatologists ...

“Teenage” red blood cells could hold the key to a malaria vaccine
Malaria parasite infection, which affects our red blood cells, can be fatal. Currently, there are about 200 million malaria infections in the world each year and more than 400,000 people, mostly children, die of malaria each year. Now, studying blood samples from patients treated for malaria at a clinical field station in Brazil’s Amazon jungle, ...

A huge leap for cloning
Animal cloning, the creation of a genetically identical copy of an individual organism, holds promise for many different reasons, including its use to conserve endangered species and to improve our understanding of developmental biology, which could eventually help us prevent or reverse developmental disorders from the get-go. Although more than 20 species of animals have ... Read More about A huge leap for cloning
Getting a grip on genetic loops
A new discovery about the spatial orientation and physical interactions of our genes provides a promising step forward in our ability to design custom antibodies. This, in turn, could revolutionize the fields of vaccine development and infection control. “We are beginning to understand the full biological impact that the physical structure and movement of our ...

Solving the DIPG puzzle a single cell at a time
For more than 15 years, pediatric neuro-oncologist Mariella Filbin, MD, PhD, has been on a scientific crusade to understand DIPG (diffuse intrinsic pontine glioma). She hopes to one day be able to cure a disease that has historically been thought of as an incurable type of childhood brain cancer. “While I was in medical school, I ...

Trial shows chemotherapy is helping kids live with pulmonary vein stenosis
Pulmonary vein stenosis (PVS) is a rare disease in which abnormal cells build up inside the veins responsible for carrying oxygen-rich blood from the lungs to the heart. It restricts blood flow through these vessels, eventually sealing them off entirely if left untreated. Typically affecting young children, the most severe form of PVS progresses very quickly ...

Science Seen: New microscope reveals biological life as you’ve never seen it before
Astronomers developed a “guide star” adaptive optics technique to obtain the most crystal-clear and precise telescopic images of distant galaxies, stars and planets. Now a team of scientists, led by Nobel laureate Eric Betzig, PhD, are borrowing the very same trick. They’ve combined it with lattice light-sheet to create a new microscope that’s able to capture real-time, incredibly ...

The softer the nanoparticle, the better the drug delivery to tumors
For the first time, scientists have shown that the elasticity of nanoparticles can affect how cells take them up in ways that can significantly improve drug delivery to tumors. A team of Boston Children’s Hospital researchers led by Marsha A. Moses, PhD, who directs the Vascular Biology Program, created a novel nanolipogel-based drug delivery system that allowed ...
