Infants With Rare Genetic Disease Saved by Cord Blood Stem Cells

...successes provide a strong argument for mandatory, universal screening of all newborns for the genetic lysosomal storage diseases. The major barrier to universal newborn screening is building an infrastructure to support widespread testing, she said. The cost of...

First technology to remove prions that cause vCJD from blood launched

...d bovine products. In 1999, the UK also instituted universal leukocyte reduction of blood to prevent the transmission of cell-associated vCJD prions. The UK also defers donors who have previously received a blood transfusion. Unfortunately, transfusion recipients are often the people most motivated to donate b...

Understanding how bacteria communicate may help scientists prevent disease

...s a model bacteria, quorum sensing appears to be a universal process in bacteria. So what he learns about the communication process known as quorum sensing could one day help scientists prevent a broad range of diseases caused by bacteria that are human pathogens. How do bacteria know how many are present? Ea...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

...e entire plant. The new discovery appears to be a universal mechanism for defense by all plants against not only bacteria and viruses, but also parasitic fungi, insects and worms, he said. "This work is important because every year, these organisms cause us to lose some 30 percent of our grain, fruit and veg...

Bioinformatics reveals new gene regulation system

...eria, the researchers thought it might represent a universal regulatory mechanism. The next question was whether the signal was promoting or repressing expression of Nrd genes. The team observed that their signal always overlapped with the promoter signal, the region of DNA required for the initiation of the ...

Caloric restriction won't dramatically extend life span in humans: UCLA research

.... While caloric restriction is likely to be almost universal in its beneficial effects on longevity, the benefit to humans is going to be small, even if humans restrict their caloric intake substantially and over long periods of time." Phelan developed the first mathematical model demonstrating the relationsh...

...rrant. Researchers have speculated that AI-2 is a universal language, and the new study from Bassler's lab is the first to show those conversations taking place ?and producing consequences -- between co-mingling species. Postdoctoral fellow Karina Xavier mixed E. coli, beneficial bacteria that live in the...

Progress on HIV/AIDS significant but insufficient

...evel of attention as they gave to global security; universal access to prevention and treatment must be ensured; money must be made to work for people on the ground; long-term strategies must be incorporated into planning and actions; and the United Nations system should maximize collective effectiveness by po...

Tiny avalanche photodiodes target bioterrorism agents

...avalanche photodiodes (APDs) that hold promise for universal biological agent detection. Once optimized, these sensitive detectors could be combined with the ultraviolet light-emitting diodes (LEDs) already pioneered by the Center for Quantum Devices to create an inexpensive detection system capable of identif...

PLoS Medicine publishes first trial of effect of male circumcision on HIV infection

...male circumcision in adulthood is a common but not universal practice. The researchers offered young sexually active uncircumcised heterosexual men the chance to be circumcised and then monitored for HIV infection. The participants (3,274 men) were randomly allocated to two different groups--one group was i...

Membrane research opens window to benefits for plants, humans

.... The researchers theorize the gating activity is universal in all plant aquaporins, because sequencing has shown the gating loop to be conserved in them. "Plant cells close their water channels in response to drought stress in order to preserve their water content," said Tajkhorshid, who also is assistant d...
