Abstract:
The present invention is directed to novel non-invasive diagnostic tools/compounds to image cancers, especially, melanoma, including metastatic melanoma in vivo. The present compounds exhibit enhanced uptake in cancerous cells and tissue, suggesting favorable selective activity of compounds according to the present invention, which can be used as effective therapeutic agents against melanoma, including metastatic melanoma. The compounds according to the present invention represent an advance in the diagnosis and treatment of melanoma, including metastatic melanoma using non-invasive molecular imaging techniques. The novel probes of the present invention are useful to initiate therapy for melanoma as well as monitor patients' response to chemotherapy treatments and other interventions or therapies used in the treatment of melanoma/metastatic melanoma. Compounds according to the present invention may be used as diagnostic and therapeutic tools for a number of conditions and diseases states, especially melanoma.
Abstract:
A device includes a body and a rechargeable battery positioned within the body. A solar cell is coupled to the body and in communication with the battery. A connector is coupled to the body and configured to engage a corresponding connector of a fiber optic cable.
Abstract:
This disclosure describes techniques for generating physically unclonable functions (PUF) from non-volatile memory cells. The PUFs leverage resistance variations in non-volatile memory cells. Resistance variations in array of non-volatile memory cells may be produce a bitstring during an enrollment process. The bitstring may be stored in the non-volatile memory array. Regeneration may include retrieving the bitstring from the non-volatile memory array.
Abstract:
This disclosure describes a structured polynucleotide, devices that include the structured polynucleotide, and methods involving the structured polynucleotide and/or devices. Generally, the structured polynucleotide includes five domains. A first domain acts as a toehold for an input DNA logic gate to initiate binding to an SCS biomolecule. A second domain acts as a substrate recognition sequence for an upstream DNA logic gate. A third domain acts as a toehold for a output DNA logic gate to initiate binding of the SCS biomolecule to the gate. A fourth domain acts as an effector sequence to alter the state of the output logic gate. A fifth domain acts as a cage sequence to lock the effector sequence in an inactive state until an input gate binds to the structured polynucleotide.
Abstract:
This disclosure provides radiolabeled compounds that bind to guanylyl cyclase C (GCC) and which can bind cancer cells that express GCC. Exemplary compounds comprise a chelating moiety capable of binding a radioactive atom, a peptide capable of binding GCC, and a linker moiety connecting the two. This disclosure also provides methods of detecting and treating cancer using the compounds described herein.
Abstract:
Apparatus and methods comprise examination of a subject using images of the subject. The images can provide a non-invasive analysis technique and can include a plurality of images of a portion of the subject at different times a temperature stimulus applied to the subject. An image of the portion of the subject can be aligned such that each pixel of the image corresponds to the same point on the subject over a sequence of images of the portion. The sequence of images can be processed after aligning the images such that data is extracted from the images. The extracted data can be used to make decisions regarding the health status of the subject. Additional apparatus, systems, and methods are disclosed.
Abstract:
In one aspect, the invention provides mesoporous silica nanoparticles (MSNPs), monodisperse populations of MSNPs and related protocells which exhibit single cell binding specificity to the substantial exclusion of non-targeted cells. For example, MSNPs and protocells of the invention may be used to target specific delivery of therapeutic agents to cancer cells or to specific blood vessel types (e.g. in the arterial, venous and/or capillary vessels or any combination of vessels). Related protocells, pharmaceutical compositions and therapeutic and diagnostic methods are also provided.
Abstract:
Provided is a method for fabricating a nanopatterned surface. The method includes forming a mask on a substrate, patterning the substrate to include a plurality of symmetry-breaking surface corrugations, and removing the mask. The mask includes a pattern defined by mask material portions that cover first surface portions of the substrate and a plurality of mask space portions that expose second surface portions of the substrate, wherein the plurality of mask space portions are arranged in a lattice arrangement having a row and column, and the row is not oriented parallel to a [110] direction of the substrate. The patterning the substrate includes anisotropically removing portions of the substrate exposed by the plurality of spaces.
Abstract:
This disclosure describes modular miRNA regulator molecules and methods of using modular miRNA regulator molecules. Generally, the modular miRNA regulator molecules include a recognition module and an inhibition module. Generally, the recognition module includes a polynucleotide in which at least a portion of the polynucleotide recognizes at least a portion of a preselected pre-miRNA. Generally, the inhibition module includes a moiety that inhibits nuclease processing of the preselected pre-RNA to a mature RNA.
Abstract:
Embodiments are directed to malaria vaccines comprising a bacteriophage VLP displaying a heterologous peptide identified by affinity selection as an anti-malaria mimotope.
