Using a patient´s own stem cells, researchers at Johns Hopkins have corrected the genetic alteration that causes sickle cell disease (SCD), a painful, disabling inherited blood disorder that affects mostly African-Americans. The corrected stem cells were coaxed into immature red blood cells in a test tube that then turned on a normal version of the gene. The research team cautions that the work, done only in the laboratory, is years away from clinical use in patients, but should...

More public awareness and education about sickle cell disease, an inherited disease that affects the blood system, is critically important, said a renowned hematologist from Baylor College of Medicine and Texas Children's Hospital. Dr. Russell E. Ware, professor of pediatrics at BCM, director of the Texas Children's Center for Global Health and director of the Texas Children's Hematology Center, offered information on the disease, what causes it, how it is treated and living with sickle...

As researchers continue to study the use of hydroxyurea as a treatment for sickle cell disease, there is more evidence to validate that it is safe and effective for children with the disease, said an expert pediatric hematologist from Baylor College of Medicine. "We've known about this treatment since the 1960s," said Dr. Russell E. Ware, professor of pediatrics at BCM, director of the Texas Children's Center for Global Health and director of the Texas Children's Hematology Center. "It was...

For the first time, researchers have successfully injected cultured red blood cells (cRBCs) created from human hematopoietic stem cells (HSCs) into a human donor, according to study results published today in Blood, the Journal of the American Society of Hematology (ASH). As the global need for blood continues to increase while the number of blood donors is decreasing, these study results provide hope that one day patients in need of a blood transfusion might become their own donors. Using...

Recent studies have shown that the heart contains cardiac stem cells that can contribute to regeneration and healing during disease and aging. However, little is known about the molecules and pathways that regulate these cells. Now, a new study utilizing a heart failure model is providing insight into one way to coax the cardiac stem cells into repairing the damaged heart. The research, published by Cell Press in the August 2011 issue of the journal Cell Stem Cell, finds that low doses of...

A new study suggests young people with a serious genetic blood disorder are not getting the right help at school, especially pupils who miss lessons due to sickness. Research funded by the Economic and Social Research Council (ESRC) at De Montfort University, the University of York and Loughborough University reveals that most children with sickle cell disease (SCD) do not feel supported by schools in catching up on absences from class. Sickle cell is an inherited condition affecting around...

A thalidomide analog is shaping up as a safe, worthy opponent of sickle cell disease, Georgia Health Sciences University researchers report. Much like hydroxyurea, the only Food and Drug Administration-approved therapy for sickle cell, pomalidomide increases production of fetal hemoglobin which, unlike its adult counterpart, cannot take on the destructive sickle shape. In stark contrast, pomalidomide also preserves bone marrow function actually increasing proliferation of the cells that make...

Donated red blood cells lose a key feature that diminishes their lifesaving power the longer they have been stored, according to researchers at Duke University Medical Center. The finding, published Friday in the journal Critical Care Medicine, details how banked blood undergoes a change during storage that decreases its ability to transport oxygen. Slowing that process could offer a way to boost the longevity and vitality of stored blood - more than 14 million units of which are used each...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
