The nanomechanical properties of single human immunoglobulin G and M antibodies were measured in a liquid environment using a fast force-volume technique with sub-10-nm spatial resolution. The ultrastructural details of these molecules were resolved in the images. Simultaneously, important physical properties, including elasticity, adhesion, and deformation were measured. The dimensions and adsorption of the immunoglobulin M antibodies onto the substrate indicated that they are highly by a low elastic stiffness （34 ± 10 MPa） flexible. The antibodies were characterized and high deformability （1.5 ± 0.5 nm）.

In this work.the one-band effective Hamiltonian governing the electronic states of a quantum dot/ring in a homogenous magnetic field is used to derive a pair/quadruple of nonlinear eigenvalue problems corresponding to different spin orientations and in case of rotational symmetry additionally to quantum number±ℓ.We show,that each of those pair/quadruple of nonlinear problems allows for the minmax characterization of its eigenvalues under certain conditions,which are satisfied for our examples and the common InAs/GaAs *** the minmax property we devise efficient iterative projection methods simultaneously handling the pair/quadruple of nonlinear problems and thereby saving up to 40%of the computational time as compared to the nonlinear Arnoldi method applied to each of the problems separately.

Despite their ubiquitous use for rendering patients unconscious for surgery, our understanding of how general anesthetics cause hypnosis remains rudimentary at best. Recent years have seen increased interest in ＂top-down＂ cortico-centric theories of anesthetic action. The aim of this study was to explore this by investigating direct cortical effects of anesthetics on cerebrocortical evok.d potentials in isolated mouse brain slices. Evok.d potentials were elicited in cortical layer IV by electrical stimulation of the underlying white matter. The effects of three anesthetics （k.tamine, etomidate, and isoflurane） on the amplitude, latency, and slope of short-latency evok.d potentials were quantified. The N2/P3/N4 potentials - which represent the early cortical response - were enhanced by etomidate （increased P3-N4 slope, P 〈0.01）, maintained by k.tamine, and reduced by isoflurane （lower N2/P3 amplitude, P 〈0.01）. These effects closely resemble those seen in vivo for the same drugs and point to a cortical mechanism independent of effects on subcortical structures such as the thalamus.

China & World Economy 2011年第4期19卷 92-108页

For some 20 years, the rate of investment by EU enterprises into China has been rising, reaching an annual average of some US$5bn over the 10 years to 2009. Conversely, the EU has not been a focus for Chinese investments, nor has Chinese investment been important to the EU despite the wide attention given to recent landmark.cross-border acquisitions. Therefore, the overall impact of Chinese investment on the European economy is small. However, this situation might now be changing following institutional changes in the EU. In light of the potential for Chinese foreign direct investment to the EU, in this paper we outline the motives for, and patterns of Chinese outward investments to the EU, and the impacts that these investments might exert on the recipient.

Fruit consumption is primarily due to the increasing awareness of consumers on the health benefits of a healthy diet. Thus some small fruits stand out because they have bioactive compounds that may have health benefits. Among these fruits is the black.erry, which contains different levels of bioactive compounds depending on the maturation stage. Therefore, the aim of this study was to evaluate the phytochemical and physicochemical compositions of black.erries (cv. Tupy) at three maturation stages. It was observed that during maturation, there was a decrease in acidity, carotenoids and tocopherols and an increase in the total soluble solids, pH, anthocyanins, antioxidant activity and total amount of phenolic compounds. Epicatequin was the major phenolic compound found in black.erries.

High-resolution microscopy opens the door for detailed single-cell studies with fluorescent reporter dyes and proteins. We used a confocal spinning disc microscope to monitor fluorescent dyes and the fluorescent protein Venus in tobacco and Arabidopsis guard cells. Multi-barreled microelectrodes were used to inject dyes and apply voltage pulses, which provok. transient rises in the cytosolic Ca^2＋ level. Voltage pulses also caused changes in the distribution of Lucifer Yellow and Venus, which pointed to a reversible increase of guard cell cytosolic volume. The dynamic cytosolic volume changes turned out to be provok.d by current injection of ions. A reduction of the clamp current, by block.ng k.＋ uptak. channels with Cs^＋, strongly suppressed the cytosolic volume changes. Cs^＋ not only inhibited the expansion of the cytosol, but also inhibited hyperpolarization-induced elevations of the cytosolic Ca^2＋ concentration. A complete loss of voltage-induced Ca^2＋ signals occurred when Ca^2＋-permeable plasma membrane channels were simultaneously block.d with La^3＋. This shows that two mechanisms cause hyperpolarization-induced elevation of the cytosolic Ca^2＋-concentration：（i） activation of voltage-dependent Ca^2＋-permeable channels, （ii） osmotically induced expansion of the cytosol, which leads to a release of Ca^2＋ from intracellular stores.
