Abstract: 9-aminonoscapine, prodrugs thereof, and pharmaceutically acceptable salts thereof, are disclosed. Pharmaceutical compositions including 9-aminonoscapine, and methods of preparation and use thereof are disclosed. 9-aminonoscapine is a noscapine analog that can be used to treat and/or prevent a wide variety of cancers, including drug resistant cancers, by binding tubulin and inducing apoptosis selectively in tumor cells (ovarian and T-cell lymphoma) resistant to paclitaxel, vinblastine and teniposide. 9-aminonoscapine can perturb the progression of cell cycle by mitotic arrest, followed by apoptotic cell death associated with increased caspase-3 activation and appearance of TUNEL-positive cells. Thus, 9-aminonoscapine is a novel therapeutic agents for a variety of cancers, including ovarian and T-cell lymphoma cancers, even those that have become drug-resistant to currently available chemotherapeutic drugs.

Abstract: Disclosed are molecules and their synthesis, for use in blocking gated ion channels such as voltage-gated sodium channels (VGSCs) and prostate voltage sodium channels (PVSCs). These inhibitors have superior blocking efficacy, for instance in displacing the radioligand [3H]-Batrachotoxin-B ([3H]-BTX-B) that binds to site 2 of a VGSC. The molecules of the invention comprise a moiety which increases the binding affinity of molecules for the protein binding site in prostate cancer cells (PCs), and which is also fluorescent. In one embodiment the invention molecules are an inhibition system that can be used to target over-abundant or hyperactive VGSCs selectively in pain, epilepsy or prostate cancer, inhibiting the proliferation of PCs. The fluorescent moiety also facilitates screening, tracking, and pharmacodynamic studies of the drug in a biological system both in vitro and in vivo.

Abstract: Methods, devices, and systems for imaging tissue and other samples or samples using infrared (IR) transmissions from coherent transmission sources, such as a wide range, tunable, quantum cascade laser (QCL) designed for the rapid collection of infrared microscopic data for medical diagnostics across a wide range of discrete spectral increments. The infrared transmissions are transmitted through, reflected from, and/or transreflected through a sample, and then magnified and/or focused prior to being detected by a detector. After detection, the sample related image data is used to assess the sample. Such methods, devices, and systems may be used to detect abnormalities in tissue, for example, before such abnormalities can be diagnosed using art cytopathological methods. The methods, devices and systems may also optionally include a visible light detection subsystem and/or a motion control subsystem to assist in control and processing of imaging.

Abstract: The present disclosure relates to photosensitive optoelectronic devices including a compound blocking layer located between an acceptor material and a cathode, the compound blocking layer including: at least one electron conducting material, and at least one wide-gap electron conducting exciton blocking layer. For example, 3,4,9,10 perylenetetracarboxylic bisbenzimidazole (PTCBI) and 1,4,5,8-napthalene-tetracarboxylic-dianhydride (NTCDA) function as electron conducting and exciton blocking layers when interposed between the acceptor layer and cathode. Both materials serve as efficient electron conductors, leading to a fill factor as high as 0.70. By using an NTCDA/PTCBI compound blocking layer structure increased power conversion efficiency is achieved, compared to an analogous device using a conventional blocking layers shown to conduct electrons via damage-induced midgap states.

Abstract: L2Relay is a novel packet relay protocol for Wi-Fi networks that can improve the performance and extend the range of the network. A device running L2Relay is referred to as a relayer, which overhears the packet transmissions and retransmits a packet on behalf of the Access Point (AP) or the node if no acknowledgement is overheard. L2Relay is ubiquitously compatible with all Wi-Fi devices. L2Relay is designed to be a layer 2 solution that has direct control over many layer 2 functionalities such as carrier sense. Unique problems are solved in the design of L2Relay including link measurement, rate adaptation, and relayer selection. L2Relay was implemented in the OpenFWWF platform and compared against the baseline without a relayer as well as a commercial Wi-Fi range extender. The results show that L2Relay outperforms both compared schemes.
