Simple idea to dramatically improve dengue vaccinations

...und that patients who got a four-component vaccine wound up only being protected against one or two versions at most, due to immunodominance. Intrigued by these results, Deem and graduate student Hao Zhou developed a precise computer model of the immune system's biochemical scanning process to see if they...

UCSD study finds anthrax toxins also harmful to fruit flies

...pted by LF treatment is similar mechanistically to wound healing, which is mediated by the same signaling pathway in humans. The EF toxin is also lethal when applied to fly larvae and can cause severe malformation in the wings of adult fruit flies--an effect that can also be understood as an interruption ...

Antibacterial coatings cut infection rates

...ve the implant from the infected site, cleanse the wound and undergo replacement surgery within a short time after original implantation, causing significant trauma, especially for the elderly," Professor Griesser said. Catheters can also be a source of bacterial infections, which can spread from the skin...

Polymer gel can block toxic leakage problem in gene therapy

...he form of a polymer compound already employed for wound healing and for drug and gene delivery. After being mixed with a gene-bearing virus, this compound -- called poloxamer 407 -- undergoes a temporary phase change as its stiffens from a liquid to a gel state when warmed to body temperature, that study...

Einstein scientists discover how protein crucial for motion is synthesised at the right place in the cell

Scientists unpick genetics of first 15 minutes of life

...sts found that the pro-nucleus in s�same mutant is wound into a tight ball that could not interact with its female counterpart, the egg pro-nucleus. This showed that there was a problem with the re-packaging process in the s�same mutant. The researchers looked at the genetic makeup of the s�same mutant a...

UNC scientists discover new role for protein as fundamental inhibitor of cell movement

... fetal development, new blood vessel formation and wound healing to occur in humans. Increased tumor cell migration also is one of the hallmarks of highly aggressive, rapidly spreading cancer tumors. The study appears in the August issue of The Journal of Cell Biology. The study indicates that CIB1 inhib...

Hurricane aftermath: Infectious disease threats from common, not exotic, diseases

...unificus can also cause serious infections, either wound infections or blood poisoning (septicemia); V. vulnificus is a bacterium that is normally present in Gulf Coast waters and is usually contracted by eating tainted seafood. It is primarily a threat to people with weakened immune systems or liver dysf...

MRSA study demonstrates need for frequent hand washing and environmental disinfection in health care settings

...ging from mild skin infections to serious surgical wound infections, pneumonia or blood infections. "The potential of MRSA to be transferred from person to person, in large part, depends on its ability to survive on environmental surfaces," says researcher Kris Owens of Ecolab, Inc. in Mendota Heights, Mi...

Typically, SNARE proteins help cells to manage the fusion of membranes of vesicles inside the cell with other spe...

Unusual antibiotics show promise against deadly 'superbugs'
