“Without iron, life itself wouldn’t be feasible,” says Barry Paw, MD, PhD. “Iron transport is very important because of the role it plays in oxygen transport in blood, in key metabolic processes and in DNA replication.”
Although iron is crucial to many aspects of health, it needs the help of the body’s iron-transporting proteins. Which is why new findings reported in Science could impact a whole slew of iron disorders, ranging from iron-deficiency anemia to iron-overload liver disease. The team has discovered that a small molecule found naturally in Japanese cypress tree leaves, hinokitiol, can transport iron to overcome iron disorders in animals.
The multi-institutional research team is from the University of Illinois, Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, Brigham and Women’s Hospital and Northeastern University. Paw, co-senior author on the new paper and a physician at Dana-Farber/Boston Children’s, and members of his lab demonstrated that hinokitiol can successfully reverse iron deficiency and iron overload in zebrafish disease models.
“Amazingly, we observed in zebrafish that hinokitiol can bind and transport iron inside or out of cell membranes to where it is needed most,” says Paw.
This gives hinokitiol big therapeutic potential. …
In 1962, the Harvard School of Public Health made a critical loan to Boston Children’s Hospital: the Harvard hyperbaric chamber. It established a new approach to pediatric heart surgery at Boston Children’s.
For many children — including a premature infant named Janet, born in 1964 with a heart murmur — the hyperbaric chamber would prove to be life-saving.
At that time, before the invention of the heart-lung bypass machine, hyperbaric chambers offered a way to operate on infants more safely. That’s because hyperbaric oxygenation, coupled with the effects of increased pressure on the respiratory system, seemed to give infants a better chance of surviving heart surgery. …
John Kheir, MD, first envisioned an injectable form of oxygen eight years ago, the night one of his patients, a nine-month-old girl, died after catastrophic lung failure. Kheir, a cardiac intensive care specialist at Boston Children’s Hospital, spoke last night to WBZ-TV’s Mallika Marshall, MD, about his efforts to try to buy precious time for children whose lungs stop working:
It was an ordinary Saturday night in the ICU at Boston Children’s, in the fall of 2006. One of my patients was a 9-month-old girl who was admitted with pneumonia, and was having trouble breathing. I had gone in to check on her just a few minutes before; although she was not feeling well, she reached out and touched my hand as I examined her. I assured her mother she was in the best possible place for her care.
Five minutes later, the code bell alarmed. Our team rushed into her room to the most horrific sight I have ever seen. …
