The high prevalence of cardiovascular diseases demands a reliable and sensitive risk assessment technique. In order to develop a fast and label-free immunosensor for C-reactive protein, a risk factor for this condition, anti-CRP antibodies were physically adsorbed to the hydrogen -terminated surface of nanocrystalline diamond. An Enzyme-Linked ImmunoSorbent Assay reference technique showed that this was a suitable substrate for antibody-antigen recognition reactions. Electrochemical Impedance Spectroscopy was used to electronically detect CRP recognition. The specificity of the immunosensor was demonstrated by incubation (...) with CRP and plasminogen as reference molecule. A different impedance behavior was observed in real-time after CRP addition as compared to plasminogen addition: the impedance increased only during CRP incubation. Fitting the data showed that this corresponded with a decrease in capacitance of the molecular layer due to its increased thickness by specific CRP recognition. Sensitivity experiments in real-time showed a clear discrimination between 1 μM, 100 nM, and 10 nM of CRP after 10 min at 100 Hz. Since, 10 nM of CRP was still clearly distinguishable from buffer solution, our CRP-directed immunosensor prototype reaches a sensitivity that is within the physiologically relevant concentration range of this biomarker in healthy controls and CVD patients. Moreover, this prototype displayed real-time discriminating power between spiked and unspiked serum, and thus also shows its applicability in this biological matrix. © 2011 Elsevier B.V.

Because the evolution of speech production is beyond our expertise (and perhaps beyond everyone's expertise) we restrict our comments to areas in which data actually exist. We provide articulatory evidence consistent with the claims made about syllable structure in adult speech and infant babbling, but we also voice some disagreement about speech errors and the typing data.

Equality is a concept that is often used in health care discussions about the allocation of resources and the design of health care systems. In secular discussions and debates the concept of equality is highly controverted and can take on many different specifications. One might think that Christians hold a common understanding of equality. A more careful study, though, makes it quite clear that equality is just as controversial among different Christian communities as it is in the secular world.

This essay delineates points of agreement and disagreement between Plato and Nietzsche with respect to the original Heraclitean argument that the underlying dynamic connective structure of the whole is ‘strife’. Also discussed is the issue of how each philosopher understands life itself, as a general process, to be related to the wider processive whole. The paper analyses how the Heraclitean understanding of the natural whole influences each philosopher's interpretation of the political structures of man. The analysis attempts to demonstrate why (...) for Nietzsche, on one hand, the value forms of the traditional polis are more in accord with human nature and nature in toto than is philosophy and why for Plato, on the other hand, when the value forms of the polis are superseded by those of philosophy it is a natural process rather than contrary to nature.

Level statistics and nodal point distribution in a rectangular semiconductor quantum dot are studied for different degrees of spin-orbit coupling. The chaotic features occurring from the spin-orbit coupling have no classical counterpart. Using experimental values for GaSb/InAs/GaSb semiconductor quantum wells we find that level repulsion can lead to the semi-Poisson distribution for nearest level separations. Nodal lines and nodal points are also investigated. Comparison is made with nodal point distributions for fully chaotic states.
