Tampa, Fla. (Feb. 14, 2011) — Transplanting autologous renal progenitor cells (RPCs), (kidney stem cells derived from self-donors), into rat models with kidney damage from pyelonephritis – a type of urinary infection that has reached the kidney – …
Researchers at the University of Illinois at Chicago have shown for the first time that damage to a particular area of the brain and a consequent reduction in noradrenaline are associated with multiple sclerosis.
The study is available online in t…
“Nucleolus”, or small nucleus, is the term coined by early biologists for the tiny structure within the nucleus which they saw under the microscope. In this structure within the nucleus, RNA molecules and proteins are assembled to form ribosomes, th…
Scientists are reporting a key advance toward development of a way to combat the terrible plant diseases that caused the Irish potato famine and still inflict billions of dollars of damage to crops each year around the world. Their study appears in …
DURHAM, N.C. — Researchers from Duke University Medical Center have identified how nanoparticles from diesel exhaust damage lung airway cells, a finding that could lead to new therapies for people susceptible to airway disease.
The scientists a…
WASHINGTON, Jan. 15, 2011 — In research described as “a stark warning” to those tempted to start smoking, scientists are reporting that cigarette smoke begins to cause genetic damage within minutes — not years — after inhalation into the lu…
A small area deep in the brain called the perirhinal cortex is critical for forming unconscious conceptual memories, researchers at the UC Davis Center for Mind and Brain have found.
The perirhinal cortex was thought to be involved, like the neigh…
Damage caused by multiple sclerosis could be reversed by activating stem cells that can repair injury in the central nervous system, a study has shown.
Researchers from the Universities of Cambridge and Edinburgh have identified a mechanism essent…
Johns Hopkins Children’s Center scientists have discovered that high blood levels of a protein commonly found in the central nervous system can predict brain injury and death in critically ill children on a form of life support called extra-corpor…

Researchers suspect that a protein superstructure called amyloid beta is responsible for much of the neural damage of Alzheimer’s disease.
A new study at the University of California, San Diego, shows that amyloid beta disrupts one of the br…
Babies are more vulnerable to serious head injury during a fall than had been previously thought, according to new research that may also begin to help child abuse investigators distinguish between accidental and intentional injury. Whitaker investigator Susan Margulies of the University of Pennsylvania found that rotational forces generated by a baby’s head hitting a hard surface can cause widespread, potentially serious brain injury. This can include internal bleeding, which can damage tissue and alter brain function, and nerve cell damage, which can impair thinking, sensation, and other mental functions.
