A tetragold(I) rectangle-like metallocage containing two pyrene-bis-imidazolylidene ligands and two carbazolyl-bis-alkynyl linkers is used for the encapsulation of a series of polycyclic aromatic hydrocarbons (PAHs), including corannulene. The binding affinities obtained for the encapsulation of the planar PAHs guests in CD2Cl2 are found to exponentially increase with the number of p-electrons of the guest (1.3 > logK > 6.6). For the bowl-shaped molecule of corannulene, the association constant is much lower than the expected one according to its number of electrons. The molecular structure of the host:guest complex formed with corannulene shows that the molecule of the guest is compressed, while the host is expanded, thus showing an unusual case of artificial mutual induced-fit arrangement.

We have designed and experimentally studied non-planar curved space plasmonic optical elements. Three different smooth curved space plasmonic structures were studied: a dome that acts either as a focu...
Intrinsically Disordered Proteins (IDPs) are a class of protein that exert their function despite lacking a well-defined three-dimensional structure, which is sometimes achieved only upon binding to t...
In this issue of Molecular Cell, Terrell et al. (2019) characterize the interactions of RAS-RAF complexes in live cells. Using bioluminescence resonance energy transfer (BRET) technology, they show t...
While pigs and rabbits are used as models for human immune diseases, FcγR binding is poorly characterized in both test species. To evaluate antibody binding to FcγRIIIA, a receptor involved in antib...
The goal of this study is to evaluate patient comfort during compression with a standard flat mammographic paddle and an investigational curved paddle. This is a study that will be perform...

The pharmacokinetics, and clinical and biological effects of MBL replacement therapy in MBL-deficient children during chemotherapy-induced neutropenia were studied.
Severe distortions in the development of many basic psychological functions that are not normal for any stage in development. These distortions are manifested in sustained social impairment, speech abnormalities, and peculiar motor movements.
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.
Three-dimensional computed tomographic imaging with the added dimension of time, to follow motion during imaging.
Methods of comparing two or more samples on the same two-dimensional gel electrophoresis gel.
