New findings challenge established views on human genome

... molecules, called RNA, and that these transcripts extensively overlap one another. This broad pattern of transcription challenges the long-standing view that the human genome consists of a relatively small set of discrete genes, along with a vast amount of so-called junk DNA that is not biologically active. ...

WHO data confirms low level of resistance to Tamiflu

... resistance to Tamiflu is very low, even when used extensively in the management of seasonal influenza," commented Dr. David Reddy, Pandemic Task Force Leader, Roche. "This provides reassurance to the scientific community that since the introduction of Tamiflu in 1999, the levels of resistance have remained sim...

DNA-damage test could aid drug development

...ething useful with it," says Lodish, whose lab has extensively studied the process by which red blood cells are generated. Shuga first worked with postdoctoral researcher Jing Zhang in the Lodish lab to adapt techniques from an established cell-culture system based on mouse fetal liver cells to create a new syst...

Study suggests some drug resistance to influenza B medications

... where zanamivir and oseltamivir are now used more extensively than anywhere else in the world. In the winter of 2004-2005, an influenza B virus caused a widespread epidemic in Japan, creating an opportunity to assess the effectiveness of neuraminidase inhibitors. The researchers collected influenza B isolates f...

Misclassified for centuries, medicinal leeches found to be 3 distinct species

...available European medicinal leeches also are used extensively by biomedical researchers studying biological processes such as blood coagulation, developmental genetics and neurobiology. Studies of commercial specimens have figured prominently in the discovery and production of anticoagulants and protease inhibi...

Stem cells act through multiple mechanisms to benefit mice with neurodegenerative disease

...d neural stem cells, which migrated and integrated extensively throughout the brain, did much more than replace brain tissue destroyed by the disease. Some of the transplanted cells replaced damaged nerve cells and transmitted nerve impulses, offering the first evidence that stem cell-derived nerve cells may int...

Twin studies reveal genetic components leading to cardiac and kidney disease

Blood transfusion-transmitted infections: A global perspective

...transfusion-transmitted infections will be debated extensively over the next few years," says Blajchman. "Regardless of the outcomes of these debates it is clear that the risk of transmission is not static. As new agents continue to emerge, old ones change their properties and epidemiologic patterns, and new...

Surprising symbiosis: Glassy-winged sharpshooter eats with friends

...rizona evolutionary biologist Nancy Moran, who has extensively studied the co-evolution of insects and their resident bacteria, recruited Eisen to the current project. "My initial interest in sharpshooter symbiosis was in the hope that we could find out exactly how xylem can be used as food," Moran explains. "It...

UCI scientists find chlorine may contribute to ozone formation

Researchers made extremely sensitive chlorine measurements, detecting the chemical at levels as low as three parts per trillion. Results showed that chlorine is ...

Making a face: A new and earlier marker of neural crest development
