Trial At Jefferson Shows New Drug May Help Cancer Patients Who Need St
A new drug may help cancer patients mobilize stem cells necessary to restore their blood-forming system after high-dose chemotherapy, according to clinical trial results. Researchers found that patients with multiple myeloma or non-Hodgkin's lymphoma who received the drug AMD-3100 along with the standard drug G-CSF (granulocyte-colony stimulating factor) had more stem cells available for transplantation than those who received G-CSF. Stem cell transplantation is front-line therapy for bone marrow cancer and certain leukemias and lymphomas. Alligator Attacks on Humans in the United States
To provide "information on alligator bites, nuisance calls, and estimated alligator population of each state, calls were made to wildlife offices in all southern US states, and an online search for lay press articles was performed. Detailed information was available from Florida and is presented regarding the types of injuries and the activities of the victims at the time of the injuries."Opens directly into a PDF file.

Nearly 500 passengers including eight with broken bones disembarked from the "Grand Voyager"cruise ship in Sardinia Tuesday a day after it was battered by a storm in the Mediterranean Sea. Fat On Chest And Upper Back Increases Risk Of Insulin Resistance
Upper trunk fat -- deposits of fat on the chest and back -- is associated with an increased risk of insulin resistance, a condition that is a precursor of type 2 diabetes, according to a new study. The presence of visceral fat, which is located between and around the internal organs, was also associated with an increased risk of insulin resistance. The researchers found that each type of fat contributes independently to insulin resistance whether or not the other type is present. New Technique Can Manipulate Light Beams
Researchers have figured out a trick to keep laser light pulses from diverging or focusing. Using a multi-layer sandwich of glass plates alternating with air, the scientists have provided the first experimental demonstration of a procedure called "nonlinearity management."This technique could be useful in future generations of devices involving optical switching and optical information processing, for which precise control of laser pulses will be advantageous. Newly Discovered Properties Of Certain Crystals Could Impact The Minia
The dashing start of electrons in a crystal does not remain without consequences for their further fate. Researchers examined the ultrafast movement of electrons in a gallium arsenide crystal exposed for a short time to a very high electrical field. This conceptually new experiment shows for the first time a collective, oscillatory motion of the electrons with ultrahigh frequency, which arises additionally to the well-known drift motion of these particles. This newly discovered effect could play an important role in connection with the miniaturization of electronic devices. Component Of Green Tea Protects Injured Livers In Mice
A new study investigating the effects of the major flavonoid component of green tea on hepatic steatosis (fatty liver) found that it significantly protected livers that suffered ischemia/reperfusion (I/R) injury in mice. I/R injury, which is caused by decreased blood flow, can lead to complications after liver transplantation. Study Uncovers Mutation Responsible For Noonan Syndrome
Scientists have discovered that mutations in a gene known as SOS1 account for many cases of Noonan syndrome (NS), a common childhood genetic disorder which occurs in one in 1,000-2,500 live births. NS is characterized by short stature, facial abnormalities and learning disabilities, as well as heart problems and predisposition to leukemia. Q&A: Ridley Scott Has Finally Created the Blade RunnerHe
The famed Director's Cut is not the final word. Blade Runner: The Final Cutwill hit theaters in Los Angeles and New York in October, with a DVD to follow in December. Obesity And The Central Nervous System -- The State Of The Art
The past decade has witnessed an explosion of information regarding the role of the central nervous system in the development of obesity and the influence of peripheral, hormonal signals that regulate CNS function to regulate food intake and metabolism.
