The potential use of G-quadruplex (GQ) stabilizing small molecules as anti-cancer drugs has created a flurry of activity on various aspects of these molecules. Telomestatin and oxazole telomestatin derivatives (OTD) are some of the most prominent of such molecules, yet the underlying dynamics of their interactions with GQ and the extent of heterogeneities in these interactions are not known. We...

Structural connectivity of the brain can be conceptionalized as a multiscale organization. The present study is built on 3D-Polarized Light Imaging (3D-PLI), a neuroimaging technique targeting the reconstruction of nerve fiber orientations and therefore contributing to the analysis of brain connectivity. Spatial orientations of the fibers are derived from birefringence measurements of unstained...

The self-assembled structure of submonolayer manganese phthalocyanine (MnPc) on Pb(111) surface is investigated by using low-temperature scanning tunneling microscopy (STM). A "holelike" superlattice, which is superimposed on the self-assembled nearly quadratic network, is observed. High resolution STM images reveal that there are two distinct azimuthal orientations of MnPc molecules. It is fou...

Crystals of the title compound (DBTTF), C(14)H(8)S(4), feature a triclinic polymorph different from two known monoclinic polymorphs. In this form, there are two independent centrosymmetric half-mol-ecules in the asymmetric unit. Although the mol-ecular orientations are relatively similar to one of monoclinic polymorphs, the packing motif is different.

As an important animal model to study the relationship between behaviour and neural activity, the mouse is able to perform a variety of visual tasks, such as orientation discrimination and contrast detection. However, it is not clear how stimulus contrast influences the performance of orientation discrimination in mice. In this study, we used two task designs, two-alternative forced choice (2AF...

SH3 binding peptides contain polyproline helices and are classified according to their binding orientations as N-to-C-terminal or C-to-N-terminal. We have tested the hypothesis that such a peptide binds in both orientations but with different populations. A focal adhesion kinase (FAK)-derived peptide was tested for its binding orientation on the Src SH3 domain. Paramagnetic tags were introduced...

a modified model has been analytically developed to describe the induction time of an elliptic air bubble in contact with an elliptic hydrophobic oil droplet. the role of hydrophobicity was revealed in the slippage of liquid over the surfaces of bubble and droplet. in this condition, the analytical relationships for pressure distribution and consequently hydrodynamic resistance force through th...

this study extends prior researches by exploring the effect of organizational orientations on export performance. building on the already extensive literature, we developed a model of relationship. a total of 120 usable questionnaires were received from the iranian food industry smes. the results indicated that entrepreneurial orientation, market orientation and learning orientation positively ...
