Laws that favor the use of diesel, rather than gasoline, engines in cars may actually encourage global warming, according to a new study. Although diesel cars obtain 25 to 35 percent better mileage and emit less carbon dioxide than similar gasoline cars, they can emit 25 to 400 times more mass of particulate black carbon and associated organic matter (“soot”) per kilometer [mile]. The warming due to soot may more than offset the cooling due to reduced carbon dioxide emissions over several decades, ac
First line chemotherapy containing Taxol is an independent predictive factor for survival
New data presented for the first time today adds to existing evidence that Taxol? offers women with metastatic breast cancer (MBC) a 31% improvement in overall survival compared to standard treatment and a 33% chance of improved progression free survival, the largest improvements ever seen. The data collected from 640 patients treated in a consecutive series of studies between 1994 and 2001 als
One of the worlds largest and most successful experimental fusion machines has been safely disassembled and cleared away. In September, staff at the U.S. Department of Energys (DOE) Princeton Plasma Physics Laboratory (PPPL) completed the dismantling and removal of the Tokamak Fusion Test Reactor (TFTR), which shut down in 1997 following 15 years of operation. During its experimental life, TFTR set records for fusion performance and made major contributions to the development of fusion as
Onkologen in Italien haben nachgewiesen, dass eine strukturierte Einführung zur Bereitstellung von Gesundheitsinformationen für Krebspatienten wirklich ihr psychologisches und physisches Befinden verbessert und dass dieses Schema in jeder Krebsstation eingeführt werden sollte. Die Ergebnisse einer Studie mit 3.300 Patienten beim Test einer Methode zur Vermittlung von Gesundheitsinformationen für Krebspatienten wurden heute (20 Oktober 2002) beim Kongress der European Society for Medical Oncology in N
Researchers recommend testing symptomatic patients for the condition
Researchers at the University of Kansas Medical Center (Kansas City) urge physicians to consider adding fructose breath testing to their diagnostic strategy for patients with unexplained abdominal pain, gas, diarrhea, and intestinal rumbling or gurgling. The recent studys results, presented at the 67th Annual Scientific Meeting of the American College of Gastroenterology, indicate that fructose malabsorption oc
The genetically – inherited disease cystic fibrosis causes severe, unrelenting lung disease in children and adults worldwide. Approximately 1 in 2,500 infants are born with this disease and only half survive past 30 years of age.
Now, researchers from the Women’s and Children’s Hospital, Adelaide have developed a novel system of gene therapy for lungs affected by cystic fibrosis, involving a natural compound found in our lungs which ’conditions’ lung airways to allow cells to take up the t
