The mediatization of the food chain in networked times
Catalan Journal of Communication & Cultural Studies, 2013Abstract This is a theoretical approach about food conceived as a process of communication. Mediatization theory is used to explore long-term changes associated with the media environment. Before, outside, but also inside, the EU institutionalization of the food chain, sense-making regarding food is facing dilemmas of the self in the ...

Surface-mediated chain reaction through dissociative attachment
Nature Chemistry, 2010Chain reactions on a surface offer an important route to linear nanopatterning. We recently reported cooperative reactions on a silicon surface in which the reaction of one halogen atom with a silicon atom of a silicon dimer induced the halogenation of its neighbouring silicon atom through surface-mediated charge transfer.

Interactions Mediated by the N-Terminus of Fibrinogen's Bβ Chain
Biochemistry, 2006Specific molecular interactions mediated by the N-terminus of fibrinogen's Bbeta chain were revealed using laser tweezers-based force spectroscopy. We examined interactions between fibrinogen fragments representing the center of the molecule, NDSK, desA-NDSK, and desAB-NDSK, and two recombinant fibrinogens, gammaD364H and gammaD364A, which have ...

Light Chain-Mediated Tubulopathies
2011Immunoglobulin light chains are low molecular weight proteins that are filtered through the glomerulus and reabsorbed into the proximal tubular epithelium by binding initially to a heteromeric receptor complex composed of megalin and cubilin. Saturation of this receptor-mediated endocytotic process results in the presence of free light chains in the ...

Lambda-Light-Chain-Mediated Anti-GBM Disease
Nephron, 2008A 77-year-old man presented with macroscopic haematuria and oligo-anuric renal failure. A renal biopsy showed moderate linear glomerular basement membrane (GBM) staining with λ light chains alone, but both circulating IgG and λ light chain activity were present. There was no evidence of a serum or urinary paraprotein and a bone marrow biopsy was normal.

Norwegian Superintendents Are Mediators in the Governance Chain
2015Transnational bodies such as OECD have had great influence in the national educational debate in Norway since the first PISA study was made public in 2001. A range of social technologies, such as participation in international rank-based tests, national standardized tests and various teacher and student surveys, have been implemented stepwise in order ...

Catalysis of Stannane-Mediated Radical Chain Reactions by Benzeneselenol
Accounts of Chemical Research, 2007The discovery and development of the catalysis of stannane-mediated radical chain reactions by benzeneselenol, generated in situ by reduction of diphenyl diselenide with tributyltin hydride, are described. The catalytic sequence is discussed in terms of polarity reversal catalysis of radical chain reactions, and applications to synthesis are presented.

Mechanical limitation of bacterial motility mediated by growing cell chains
Biophysical Journal, 2022Contrasting most known bacterial motility mechanisms, a bacterial sliding motility discovered in at least two gram-positive bacterial families does not depend on designated motors. Instead, the cells maintain end-to-end connections following cell divisions to form long chains and exploit cell growth and division to push the cells forward.

Lipase-mediated Resolution of Branched Chain Fatty Acids
Biocatalysis and Biotransformation, 2002Branched chain fatty acids (BCFAs) are fatty acids substituted with alkyl groups. Many of them are chiral and therefore occur in two enantiomeric forms. This review describes their occurrence in Nature, their biosynthesis, their properties as flavours, and their enzymatic kinetic resolution.

Zinc-Mediated Chain Extension of β-Keto Phosphonates
The Journal of Organic Chemistry, 2000A variety of beta-keto phosphonates can be converted to gamma-keto phosphonates through reaction with ethyl(iodomethyl)zinc. The presence of alpha-alkyl substituents, Lewis basic functionality, and modestly acidic NH-protons are accommodated in substrates of this reaction.
