Abstract: Provided are conducting polymer nanofibers, methods of making conducting polymer nanofibers, and uses thereof. The conducting polymer nanofibers can be formed by, for example, electrospinning, force spinning, and centrifugal spinning using a spinning dope. The conducting polymer nanofibers can be used in devices, such as a radiation detecting device.

Abstract: Electro-osmosis is used to create droplets in order to easily, carefully, and quickly pick-and-place millions of objects (ranging in size from millimeters to nanometers) individually or in parallel. Droplets are formed within channels that are individually controlled in order to achieve a predetermined configuration of the selected objects.

Abstract: The androgen receptor (AR) is the key driver of prostate differentiation and prostate cancer (PC) progression, and androgen ablation is the cornerstone of advanced PC treatment. Prostate-specific membrane antigen (PSMA) represents another target of interest in PC. Previous publications have reported inconsistent associations between androgen levels and PSMA expression. Using a panel of prototypical human PC cell lines, this relationship is clarified. PSMA is a biomarker that distinguishes AR-positive/PSMA-positive adenocarcinomas from AR-negative variants. PSMA is a cell surface barometer of androgen activity that can be readily identified by immunohistochemistry and/or in vivo imaging. Given that anti-androgen therapy is likely to remain a cornerstone of PC treatment, the associated up-regulation of PSMA, as well as its other characteristics, makes it a compelling target opportunity in PC.

Abstract: A nanodevice includes a substrate that has an elongated channel with a plurality of nanoscale critical dimensions arranged as a stepped gradient across a width of the elongated channel.

Abstract: Prostate cancer (PC) is an entity that encompasses different types of tumors, including adenocarcinomas and non-adenocarcinomas. Adenocarcinomas and non-adenocarcinomas respond to, and therefore should be treated, with different treatments. Even within the adenocarcinomas, the lethality of tumors is highly variable, from low risk/indolent/non-life threatening to high risk/lethal. The inability to accurately predict the behavior of a particular cancer makes treatment decisions difficult and highly inexact. Elevated expression of prostate specific membrane antigen (PSMA) expression is a molecular hallmark of lethal prostate adenocarcinoma. Assessment of PSMA expression levels to predict the behavior of a particular cancer will be useful in the diagnosis and treatment of PC.

Abstract: The present invention relates to nano structures of metal oxides having a nanostructured shell (or wall), and an internal space or void. Nanostructures may be nanoparticles, nanorod/belts/arrays, nanotubes, nanodisks, nanoboxes, hollow nanospheres, and mesoporous structures, among other nanostructures. The nanostructures are composed of polycrystalline metal, oxides such as SnO2. The nanostructures may have concentric walls which surround the internal space of cavity. There may be two or more concentric shells or walls. The internal space may contain a core such ferric oxides or other materials which have functional properties. The invention also provides for a novel, inexpensive, high-yield method for mass production of hollow metal oxide nanostructures. The method may be template free or contain a template such as silica. The nanostructures prepared by the methods of the invention provide for improved cycling performance when tested using rechargeable lithium-ion batteries.

Abstract: A device comprising a single closed loop of elastic filament configurable between (i) a first configuration for movement along a blood vessel; and (ii) a second configuration for lodging within a blood vessel, the second configuration providing a single flow-restricting face sized and configured to cover the mouth of the aneurysm and obstruct blood flow to the aneurysm while permitting substantially normal blood flow through the blood vessel, with the degree of obstruction at the mouth of the aneurysm being such that the aneurysm thromboses when the face is positioned over the aneurysm, the flow-restricting face comprising a plurality of lengths of the closed loop of filament disposed in close proximity to one another in a switchback configuration, and at least one leg for holding the flow-restricting face adjacent the mouth of the aneurysm, the leg configured so as to maintain substantially normal blood flow through the blood vessel.

Abstract: The present invention relates to a method and kit for identifying a translation initiation site on an mRNA. The method involves contacting a first mRNA with a first translation inhibitor to preferentially stabilize one or more initiation ribosomes at translation initiation sites on the first mRNA. A second mRNA is contacted with a second translation inhibitor different from the first translation inhibitor to stabilize one or more initiation ribosomes and one or more elongation ribosomes on the second mRNA. The location of ribosomes stabilized on the first mRNA is compared to the location of ribosomes stabilized on the second mRNA.
