Toddler Avoids Transplant, Mended Heart Is Second Chance at Life

Just two years old at the time, Zoey Jones was told she would need a heart and lung transplant for her failing organs, a complication due to the single ventricle heart defect she was born with. She was referred to Nationwide Children’s Hospital where they began to prepare for a transplant, when a second look in the catheterization laboratory (cath lab) led doctors to believe her heart and lungs were strong enough to avoid transplant altogether.

Study Details Molecular Mechanism That Regulates How the Heart Pumps Blood

In a finding that could lead to new drugs to treat heart failure, researchers have uncovered the molecular mechanism that regulates how the heart pumps blood. The finding is published in the Proceedings of the National Academy of Sciences. The key molecular player in this mechanism is a giant protein called titin, according to a study led by senior author Pieter de Tombe, PhD of Loyola University Chicago Stritch School of Medicine. The study was published Feb. 8, 2016 in Proceedings of the National Academy of Sciences.

Scientists Propose "Pumpjack" Mechanism for Splitting and Copying DNA

New close-up images of the proteins that copy DNA inside the nucleus of a cell have led a team of scientists to propose a brand new mechanism for how this molecular machinery works. The scientists studied proteins from yeast cells, which share many features with the cells of complex organisms such as humans, and could offer new insight into ways that DNA replication can go awry.

Mayo Researchers Identify New Borrelia Species that Causes Lyme Disease

Mayo Clinic researchers, in collaboration with the Centers for Disease Control and Prevention (CDC) and health officials from Minnesota, North Dakota and Wisconsin, have discovered a new bacterial species that causes Lyme disease in people. The new species has been provisionally named Borrelia mayonii. Prior to this finding, the only species believed to cause Lyme disease in North America was Borrelia burgdorferi.

Muscles on-a-Chip Provide Insight Into Cardiac Stem Cell Therapies

Stem cell-derived heart muscle cells may fail to effectively replace damaged cardiac tissue because they don’t contract strongly enough, according to a study in The Journal of Cell Biology. The study, “Coupling Primary and Stem Cell-Derived Cardiomyocytes in an In Vitro Model of Cardiac Cell Therapy,” by Yvonne Aratyn-Schaus and Francesco Pasqualini and colleagues, may help explain why stem cell-based therapies have so far shown limited benefits for heart attack patients in clinical trials.

IFT Launches New Website To Help Consumers Find Out the Facts on Food

Consumers have a lot of questions about where their food comes from, how it’s made and what’s in it. To help consumers find this information, the Institute of Food Technologists (IFT) is excited to announce the launch of “IFT Food Facts.” IFT Food Facts is an online resource that has videos and fact sheets with tips related to the science of food that consumers can use at home, at the store and on the go. IFT’s member experts answer common questions about food safety, nutrition, and food chemistry, as well as address common myths and misperceptions about food science and technology.
