    Abstract: A method of preparing a crystalline contrast agent for magnetic resonance imaging from a zwitterionic carboxylic pyridyl ligand includes mixing metal ion and the pyridyl ligand and obtaining crystals therefrom. The crystalline contrast agent includes a manganese-organic or gadolinium-organic 3D framework. The crystalline contrast agent is employed in a kit and a pharmaceutically acceptable composition. The method allows for preparing crystalline contrast agents with superior properties with easily available starting materials and with an economic and efficient process. The method allows for preparing crystalline contrast agents with exceptional water-stability and water-solubility, which exhibit high longitudinal relaxivities and with excellent stabilities under physiological conditions and low cytotoxicity. Further provided is a method for in vivo imaging of a subject, in particular a human, comprising administering the crystalline contrast agent to the subject.

    Abstract: A method of preparing a crystalline zwitterionic zinc(II)-carboxylate compound includes the steps of preparing a mixture of zinc(II) ions and a first pyridyl ligand having three carboxylic acid moieties; subjecting the mixture to conditions under which a precipitate is formed; separating the precipitate; adding a solvent and optionally a second pyridyl ligand to the separated precipitate; subjecting the obtained mixture to conditions under which crystals of the zwitterionic zinc(II)-carboxylate compound are formed; and separating the crystals of the zwitterionic zinc(II)-carboxylate compound. Preferably but not exclusively, the crystalline zwitterionic zinc(II)-carboxylate compound essentially consists of at least one 1D coordination polymer. The compounds are suitable for providing a sensing platform for detecting the presence or amount of target nucleic acid, particularly HIV-1 ds-DNA, with specificity, and, thus, a method of detecting a target nucleic acid sequence in a sample and a kit including the compounds and an oligonucleotide probe are also provided.

    Abstract: A compound for treating a disease, in particular cancer like non-small cell lung cancer, exceptionally inhibits activity of oncogenic ALK kinase. Compositions, particularly pharmaceutical compositions, are provided comprising this compound. Methods for targeting cancer cells harboring an abnormality in the ALK gene are also The compound for treating a disease has certain structural elements, namely a tricyclic, more specifically heterocyclic, backbone as the core part of the compound at least one highly electronegative atom in form of a tertiary amine attached to the backbone via an at most 6-membered linking group with a terminal highly electronegative atom in form of a nitrogen as secondary amine, and a further hydrophobic moiety fused to the backbone. The structural components allow for an advantageous interaction with the ALK kinase domain. The compound therefor represents a highly promising treatment option for patients in particular those bearing ALK-dependent non-small cell lung cancer.

    Abstract: A method for treating a subject suffering from a cancer, in particular a multidrug-resistant cancer includes administrating a cobalt-polypyridyl complex to the subject. A method for suppressing the growth of cancer cells, in particular inducing autophagy of the cancer cells, inducing cell cycle arrest of the cancer cells and/or inhibiting cell invasion of the cancer cells and for specifically targeting cancer cells with multidrug-resistance includes contacting said cancer cells with the cobalt-polypyridyl complex. A pharmaceutical composition and a kit are provided and include the cobalt-polypyridyl complex. Unexpectedly, the cobalt-polypyridyl complex is especially suitable to treat cancer, in particular multidrug-resistant cancer with an exceptionally increased cytotoxic activity towards multidrug-resistant cancer cells.

    Abstract: In widely deployed wireless “hot-spot” networks, nodes frequently join or leave, inelastic/elastic and saturated/non-satuarted flows coexist. In such dynamic and diverse environments, it is challenging to maximize the channel utilization while providing satisfactory user experiences. In this invention, one proposes a novel contention-on-demand (CoD) MAC scheme to address this problem. The CoD scheme consists of a fixed-CW algorithm, a dynamic-CW algorithm, and an admission control unit. The fixed-CW algorithm allows elastic flows to access limited system bandwidth; the dynamic-CW algorithm enables inelastic flows to contend for channel on demand and quickly adapt to network change; and the admission control unit rejects overloaded traffic for providing good user experiences. One then performs an asymptotic analysis to develop a simple but efficient admission control rule. Finally, extensive simulations verify that the scheme is very effective and the theoretical result is very accurate.
