Hemoglobin-Based Agent Reduces Need for Transfusion During Heart Surgery

A Phase II clinical trial conducted at Duke University Medical Center and five other U.S. institutions has shown that an agent made of purified human hemoglobin appears safe and may be effective when used instead of transfused human blood to replace blood lost during heart surgery.

If the benefits of the agent, known as hemoglobin raffimer, are proven in subsequent Phase III clinical trials, physicians would not need to use as much donated blood during surgery, the researchers said. An esti

In face of changes in precipitation variability, climatic extremes

What does Kansas’ weather and life have in common? In the words of Forrest Gump, both are like a box of chocolates. “You’re never sure what you’re going to get.” Rain or drought. Drought or rain.
Concerns about future climate changes resulting from human activities often focus on the effects of increases in average air temperatures or changes in average precipitation amounts. But climate models also

Nicotine patch effective without direct counseling

Nearly 20 percent of smokers using an over-the-counter nicotine patch in a new study were able to quit smoking entirely after six weeks, compared to only 7 percent of smokers using a dummy patch. Each group reported only mild side effects from patch use, like rashes or insomnia.

None of the smokers received any direct instruction on how to use the patch or got behavioral counseling to help them quit smoking, which suggests that nicotine patches used in an over-the-counter manner can be safe

Observing proteins and cells in the wild

’Quantum dots’ may allow researchers to track proteins and cells in their natural environments

Imagine if molecular and cell biologists could watch proteins and cells at work in their natural habitat in the same way that wildlife biologists observe animals in the wild. They’d sit back and witness first hand their microscopic subjects’ daily routines, interactions and movements, and the places they prefer to be.

This fantasy is rapidly becoming a reality t

UT Southwestern scientists uncover new mechanism by which cells rid themselves of damaged proteins

Scientists at UT Southwestern Medical Center at Dallas have identified a new and surprising mechanism by which a class of enzymes responsible for the breakdown of proteins operates.

The process of degrading proteins no longer needed by cells is essential in the normal growth, development and regulation of cells, and the study’s findings have implications for understanding diseases like Parkinson’s and several forms of cancer.

“Many diseases involve the inappropriate accumu

Researchers Discover Gene that Controls Learned Fear

Researchers have discovered the first genetic component of a biochemical pathway in the brain that governs the indelible imprinting of fear-related experiences in memory.

The gene identified by researchers at the Howard Hughes Medical Institute at Columbia University encodes a protein that inhibits the action of the fear-learning circuitry in the brain. Understanding how this protein quells fear may lead to the design of new drugs to treat depression, panic and generalized anxiety di
