UCSF-led team reports new test improves detection of prions in animals

UCSF-led researchers have developed a highly sensitive, automated test for detecting prions (PREE-on) that they report significantly improves the accuracy and speed of detecting the various forms of the infectious agent, which causes a set of neurodegenerative diseases, in cattle, sheep, deer and elk.

Because the test is automated, the researchers say, it could be used for high-throughput testing of brain samples of cattle with bovine spongiform encephalopathy (BSE), or “mad cow” disease, a

Finding a ’Holy Grail’: simulated and experimental protein folding compares nicely

For years, the comparison of simulated and experimental protein folding kinetics has been a “Holy Grail” for biologists and chemists. But scientists seeking to confirm protein-folding theory with laboratory experiments have been unable to cross the microsecond barrier. This obstacle in time existed because experiments could not be performed fast enough, nor simulations run long enough, to permit a direct comparison.

Now, measurements from the University of Illinois at Urbana-Champaign and m

World-first gene therapy for cystic fibrosis targets lung stem cells?

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

Neues Informationsprogramm beruhigt Patienten

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

Onkologen beurteilen die chinesische Arzneimitteltherapie

Ein innovativer Versuch eines Tests, von traditionellen chinesischen Arzneimitteln mit westlichen Forschungsmethoden, wurde von Onkologen in Hongkong entwickelt, um den Stellenwert der chinesischen Arzneimitteltherapie innerhalb eines Programms zur konventionellen Behandlung zu beurteilen.

Bei seiner (19 Oktober 2002) Rede auf dem Kongress der European Society for Medical Oncology in Nizza, Frankreich, sagte Dr. Tony Mok von der Chinese University of Hongkong, “Sehr viele Personen in China

Chips zur Analyse von Krebsgenen

Wie am 19 Oktober 2002 den Delegierten bei dem Kongress der European Society for Medical Oncology in Nizza mitgeteilt wurde, dürfte sich die Chip Technology zur Auswertung von genetischen Informationen in der Zukunft als eines der wichtigsten Instrumente für die Krebsprognose herausstellen.

Krebs wird durch Veränderungen oder Mutationen in Genen und durch andere Zellanomalien ausgelöst. Die Informationen des Human Genome Project bieten jetzt ein wertvolles Werkzeug, um die genetische Basis
