Deamination unlocks diversity

A key cytokine unlocks the door.

A key cytokine unlocks the door The synthesis and secretion of a variety of pro-inflammatory cytokines are increased in the chronic inflammatory reaction associated with Helicobacter pylori infection. 1 In this issue (see page 24), Shibata and colleagues confirm increased secretion of tumour necrosis factor (TNF) by the inflamed mucosa, and provide evidence that during H pylori infection there ...

A Locking Algorithm with Premature Unlocks

Standard locking protocols exhibit superior performance than other families of concurrency control mechanisms under a wide range of database (DB) workloads and system conngurations. Nevertheless, they have some drawbacks such as unnecessary waiting, which cause an unacceptable behaviour particularly in environments where long transactions (long TAs (LTAs)) are present. In this paper a locking a...

Sodium ion unlocks understanding of channel blockade

New simulations explain how several types of drugs block sodium channels.

Activated OCP unlocks nonphotochemical quenching in cyanobacteria.

Most aerobic photosynthetic organisms have enough light-harvesting capacity so that on bright sunny days their photosynthesis is saturated for the major part of the day (1, 2). Early on in such sunny days the capacity of the reaction centers to process the absorbed solar energy is exceeded. The excess absorbed photons are potentially very dangerous. For example, if the chlorophyll-excited singl...
