Major milestone in the culturing of human blood stem cells

Patients with leukemia, certain autoimmune diseases and genetic defects such as sickle-cell anemia can be treated with blood stem cells either from a donor's bone marrow or from cord blood - but the supply of effective stem cells often runs short.

How a red blood cell loses its nucleus

Unlike the rest of the cells in your body, your red blood cells lack nuclei.

Chronic pain is a disease in its own right

The concept that chronic pain is a disease in its own right is leading to new specific treatments aimed at physical, psychological, and environmental components of this major disease, including genetic predisposition, according to a world renowned pain medicine expert.

New control mechanism for genetic code translation discovered in bacteria

Almost all organisms, from bacteria to human beings, share the same genetic code, a group of universal instructions used to convert DNA or RNA sequences into proteins, the "building blocks" of life.

Two-way cell talk provides clues about neuromuscular disease

It's a scientific given that neurons tell other cells what to do, but new evidence suggests that, like with any good relationship, these target cells also have much to contribute, scientists say.

Stomach flu vaccine possibility

Every year, millions of people are infected with noroviruses - commonly called "stomach flu" - often resulting in up to 72 hours of vomiting and diarrhea.

Search for genes tied to social behavior

The first genome-wide search for genes governing social behavior has found that even the simplest social creatures - the amoebae Dictyostelium discoideum - have more than 100 genes that help regulate their cooperative behavior.

Location location location, even for genes

Moving an active gene from the interior of the nucleus to its periphery can inactivate that gene report scientists from the University of Chicago Medical Center in an article to be published early online Feb.13, 2008, in the journal Nature.

Gene chip technology used to distinguish ventilator-associated pneumonia from underlying critical illness

Critically ill patients who need a ventilator to breathe face a high risk of pneumonia.

Scientists discover why some breast cancers are drug resistant

Research by British scientists has revealed how cancer cells which have a faulty gene can become resistant to treatment.

Tonsillectomy and adenoidectomy surgery improves quality of life for children with sleep apnea

For children who suffer from obstructive sleep apnea (OSA), a tonsillectomy and adenoidectomy can provide dramatic relief and is successful in solving sleep problems for 80 to 90 percent of children, a Saint Louis University study found.

Discovery of 'overdrive' protein could broaden drug design options

New research by scientists at the University of North Carolina at Chapel Hill shows for the first time that an important family of proteins known to function at the cell surface also functions at a site within the cell.

Scientists reprogram human skin cells into embryonic stem cells

UCLA stem cell scientists have reprogrammed human skin cells into cells with the same unlimited properties as embryonic stem cells without using embryos or eggs.

Potential method for repairing misspelling in DNA code that causes spinal muscular atrophy

Researchers at the University of Delaware have discovered a novel technique - that acts like a "spell-checker" for correcting a misspelling in the DNA code - to repair the defective gene that causes spinal muscular atrophy (SMA).

Discovery of previously unknown mechanism that leads to cleft palate

By creating a genetic mutation in zebrafish, University of Oregon scientists say they've discovered a previously unknown mechanism for cleft palate, a common birth defect in humans that has challenged medical professionals for centuries.

Cancer cells adapt using Darwin's 'survival of the fittest' principle to resist treatment

Scientists in London have discovered a new genetic mechanism which helps cancer cells survive by changing the way they respond to treatment.
