Mystery Behind Sleepiness After the Meal Revealed

...-seeking and addiction. 'We have identified the pore in the membrane of orexin-producing cells that is responsible for the inhibiting effect of glucose. 'This previously unknown mechanism is so sensitive it can detect minute changes in glucose levels – the type that occurs between meals for example....

Treatment of Bacterial Infection Paves the Way to Treat CF Infection

... crystallographer Marianne Cuff saw a bagel-shaped pore that might be involved in transferring toxins into cells. She deposited the structure of the protein, called Hcp1, into the Protein Data Bank, a resource used by biologists worldwide to find information about the proteins they are studying. While exp...

...halting flow of signals. "We have identified the pore in the membrane of orexin-producing cells that is responsible for the inhibiting effect of glucose. This previously unknown mechanism is so sensitive it can detect minute changes in glucose levels - the type that occurs between meals for example," sa...

Drexel Research in Cytokines Could Treat Sepsis

...g the last century and only a limited control over pore size can be achieved. The U.S./U.K. team has de...ability to fine-tune the carbon microstructure and pore size to target a specific application,” says Yury Gogotsi, director of the A. J. Drexel Nanotechnolo...

Bacteriophages may Boost the Effectiveness of Antibiotics

...nisms that enable them to throw out antibiotics. A pore in the cell wall would obviously cancel the efflux effect,' Hagens explains. Pseudomonas bacteria cause pneumonia and are a common cause of hospital-acquired infections. Experiments in mice revealed that 75% of those infected with a lethal dose o...

New Microchip for Protein Sorting

...he microchip is that it can have so many different pore sizes, and unlike gels, it is possible to design an exact pore size to increase the separation accuracy. That in turn can help researchers look for so-called bioma...

New Mechanism for Nutrient Uptake Discovered

... at the surface of the cell's outer membrane. Each pore is capable of transporting nutrients individually, so we were really surprised to find that the pores simply can't act without stimulation from their neighbors." In earlier research the Carnegie scientists, with colleagues, identified the genes res...
