Clue found to Epstein-Barr virus' ability to form and sustain tumors

...ein, it will be easier for us to develop assays to screen for small molecules that will compete with the protein in binding to EBNA-1," Sugden says. "By preventing the cellular protein from binding with the segment, EBNA-1 will not be able to carry out its function and the tumor cells it sustains will die."...

'GreeneChip' -- New diagnostic tool that rapidly and accurately identifies multiple pathogens

... for single pathogens, methods that simultaneously screen for multiple agents are important, particularly when early accurate diagnosis can alter treatment or assist in containment of an outbreak," stated W. Ian Lipkin, MD, director of the Greene Infectious Disease Laboratory at the Mailman School’s Departm...

Stroke symptoms common among general population

...he JAMA/Archives journals. Using brain imaging to screen individuals without a history of stroke reveals that many have had an undiagnosed or silent stroke, according to background information in the article. One previous study found that 11 percent of individuals age 55 to 64, 22 percent of those ages 65...

Transmission of antibiotic-resistant bacteria linked to previous intensive care unit room occupants

...carried MRSA and 658 carried VRE, leaving 7,629 to screen for the acquisition of MRSA and 7,806 for acquisition of VRE. The average patient age was 61 years, and 58 percent were male. Fourteen percent of these ICU patients stayed in rooms in which the prior occupant had MRSA and 13 percent stayed in rooms...

Carnegie Mellon scientists use 'green' approach to transform plastics manufacturing

ATRP differs significantly from conventional polymer manufacturing methods. This "living," synthetic process ...

Scientists design simple dipstick test for cocaine, other drugs

...irst responders or emergency room staff to quickly screen individuals for a variety of drugs and other chemicals." Lu said. Aptamers are single-stranded nucleic acids that can bind to specific molecules in three-dimensions. For each molecular target, such as cocaine, a corresponding aptamer can be selecte...

MIT's molecular sieve advances protein research

...ze of a thumbnail. The sieve makes it possible to screen proteins by specific size and shape.In contrast, the current technique used for separating proteins, gel electrophoresis, is time-consuming and less predictable. Pore sizes in the gels vary, and the process itself is not well understood by scientists...

A fisheye view of the deadliest breast cancer

...ggressive of human breast cancers, and to rapidly screen for drugs that might stop IBC, researchers at the University of California, San Diego (UCSD), have come up with an unlikely yet extremely promising ally: a transparent fish suitable for xenografts. More properly, it’s a transgenic zebrafish, a tro...

Nano-devices hold promise for early-stage cancer detection

...heter, or woven into fabric. Their function is to screen for, detect, and potentially treat, cancer and other diseases when they are still at a single-cell size in early development stages. They will also detect harmful pathogens in food and water. Engineering researchers at McMaster University will be e...
