Figure 1: A single PTCDA molecule adsorbed on the Si(111)-(7 × 7) surface. (a) An STM image atVs=+500 mV. Scale bar, 1 nm. The five arrows indicate stripes corresponding to a molecular orbital. (b) Schematic view of the arrangement of a PTCDA molecule adsorbed onto the surfa...
It exhibits the expected square pyramidal geometry about Co, and forms hydrogen-bonded dimers through amide N—H groups and phenolate O atoms on an adjacent molecule. The involvement of only half of the salen ring structure in hydrogen-bonding interactions results in slight folding of the salen ...
Atomic Force Microscopy (AFM) is a powerful tool to study DNA structure at single molecule level. We here report a comprehensive analysis by AFM of DNA plasmid molecules with defined supercoiling degree, covering the full spectrum of biologically relevant topologies, under different observation ...
Citrullination is a post-translation modification of proteins, where the proteinaceous arginine residues are converted to non-coded citrulline residues. Th
The Fc portion of the molecule frequently has little role in the design and function of these assays except in those which use some effector function such as complement fixation as a detection device or staph protein A as a separation. In solid-phase and two-site immunometric assays, ...

24. Each rod is also associated with an interrod, which consists of crystals arranged at a ~60° angle to the rod axis13. Crystal elongation direction varies gradually from the rod to the interrod25,26,27. Each rod is wrapped in a sheath of organic matrix, whereas crystals within the ...
Bacterial σI factors of the σ70-family are widespread in Bacilli and Clostridia and are involved in the heat shock response, iron metabolism, virulence, and carbohydrate sensing. A multiplicity of σI paralogues in some cellulolytic bacteria have been

In the placental villi, nearly the entire maternofetal and fetomaternal exchange takes place. There is only a limited contribution to this exchange by the extraplacental membranes. In addition, most metabolic and endocrine activities of the placenta have
