Researchers use clever screening methods to speed vaccine production

Infectious diseases-both old and new-continue to exact a devastating toll, causing some 13 million fatalities per year around the world. Vaccines remain the best line of defense against deadly pathogens and now Kathryn Sykes and Stephen Johnston, researchers at Arizona State University's Biodesign Institute, along with co-author Michael McGuire from the University of Texas Southwestern Medical Center are using clever functional screening methods to attempt to speed new vaccines into production that are both safer and more potent.

UMD researchers design molecular container that can increase solubility of drugs

A cross-disciplinary team of researchers at the University of Maryland has designed a molecular container that can hold drug molecules and increase their solubility, in one case up to nearly 3000 times. Their discovery opens the possibility of rehabilitating drug candidates that were insufficiently soluble. It also offers an opportunity to improve successful drugs that could be made even better with better solubility.

Reusable grocery bag can play a role in spreading norovirus infection

Oregon investigators recently mapped the trail of an outbreak of a nasty stomach bug among participants in a girls' soccer tournament to a reusable open top grocery bag stored in a hotel bathroom. Their findings, which illustrate the role that inanimate objects can play in spreading norovirus infection, appear in The Journal of Infectious Diseases.

Cascades Tissue Group applauds third annual ‘STOP! Clean Your Hands Day’

North America's fourth largest producer of towel and tissue paper, Cascades Tissue Group, applauds the third annual "STOP! Clean Your Hands Day," today, May 7, for building greater awareness for the importance of hand hygiene. The day also marks a good time to note that paper towels are the most hygienic choice when it comes to drying hands.

Chesapeake Regional Medical Center rolls out automated disinfection robot

Chesapeake Regional Medical Center rolled out the newest member of its environmental team last week, a five-foot, automated disinfection robot named Tru-D (Total Room Ultraviolet Disinfection). Implementation of the mobile, high-tech disinfection device is part of a $2 million CDC grant awarded to Duke University for the prevention of healthcare-associated infections (HAI's).

One of the controversial avian flu studies published in full finally

After endless debates and controversies on whether two studies that demonstrated how bird flu, also known as avian H5N1 influenza, or avian flu, should be published, one of them has appeared in the latest issue of the journal Nature in its entirety. The two studies aimed for publication in journals Nature and Science show how the bird flu virus could become transmissible from mammal-to-mammal; as humans are mammals, the same would apply to humans.

E coli detection in contaminated meat to be ‘sped up’ says USDA

The government is gearing up to speed up the process for tracking E. coli in meat, a move that will help authorities more quickly find the source of bacteria outbreaks and hasten recalls of contaminated food.

Non-coding RNA gives off biological signals during viral infection

Once considered unimportant "junk DNA," scientists have learned that non-coding RNA (ncRNA) - RNA molecules that do not translate into proteins - play a crucial role in cellular function. Mutations in ncRNA are associated with a number of conditions, such as cancer, autism, and Alzheimer's disease.

Immunosignatures can yield reliable and highly stable diagnostic results

Identifying diseases at an early, presymptomatic stage may offer the best chance for establishing proper treatment and improving patient outcomes. A new technique known as immunosignaturing harnesses the human immune system as an early warning sentry-one acutely sensitive to changes in the body that may be harbingers of illness.

NSABB calls for global guidelines for conducting, communicating research involving dangerous pathogens

NewScientist reports on the U.S. National Science Advisory Board for Biosecurity's (NSABB) recommendation that revised versions of two controversial studies on H5N1 avian flu be published in scientific journals, reversing its previous recommendation that the studies only be published if certain details were withheld. According to the news service, dissent among the board members over the issue has prompted the committee to "propose talks to draft global guidelines for doing and communicating work involving dangerous pathogens."

New brain cancer vaccine with material from own tumors proves effective in clinical trial

A new brain cancer vaccine tailored to individual patients by using material from their own tumors has proven effective in a multicenter phase 2 clinical trial at extending their lives by several months or longer. The patients suffered from recurrent glioblastoma multiforme-which kills thousands of Americans every year.

Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.
