APRIL 2005 G ranulocyte colonystimulating factor (G-CSF) is a 19-kDa glycoprotein that stimulates proliferation, maturation, and functional activation of cells in the granulocyte lineage. Recombinant G-CSF is widely used to ameliorate neutropenia resulting from myelosuppressive chemotherapy and bone marrow transplantation as well as to mobilize peripheral blood progenitor cells for transplantat...

We introduce pyrogallol end-functionalized telechelic PEGs that are crosslinked with di- or trivalent ions to result in self-healing, adhesive hydrogels whose mechanical properties can be varied over an unprecedented range.

polyethylene glycol (peg) is a hydrophilic polymer, known to be capable to fuse numerous single cells in vitro, to join the membranes of adjacent neurons and giant invertebrate axons, and to seal damaged neural membranes. the molecular mechanism of the action of peg is still unknown. it is believed that peg dehydrates membranes and enables their structural components to resolve and rearrange in...

This paper analyses predictions of a simple model of currency crises in which the peg will be abandoned when the currency overvaluation hits a certain threshold, unknown to the agents. Due to learning about the threshold, some features usually observed in the data and identified with models with multiple equilibria arise in the model. But the model yields distinctive predictions about the behav...

BACKGROUND Hemozoin (Hz) is a heme crystal that represents a vital pathway for heme disposal in several blood-feeding organisms. Recent evidence demonstrated that β-hematin (βH) (the synthetic counterpart of Hz) formation occurs under physiological conditions near synthetic or biological hydrophilic-hydrophobic interfaces. This seems to require a heme dimer acting as a precursor of Hz crystals ...
