Abstract: A medical device for retrieval of kidney stone fragments from a urinary tract is provided. The medical device has a plurality of magnets arranged within a flexible sheath forming a flexible wire. The magnets are magnetically attached end-to-end and arranged with their magnetic polarities alternating in direction. The magnetization direction of each of the magnets is orthogonal to the length axis of the flexible wire. A removable inner stylet is situated within the flexible sheath allowing for modifiable flexibility of the wire. The medical device is dimensioned to be introduced into the urinary tract and standard endoscopic devices. The medical device is further dimensioned to allow for the wire with magnetically attached stone fragments to be retrieved from the urinary tract. The magnetic field along the length axis is sufficient to attract to the surface of the flexible wire superparamagnetic nanoparticles which have bound themselves to kidney stone fragments.

Abstract: In certain examples, methods and semiconductor structures are directed to multilayered structures including TMD (transition metal dichalcogenide material or TMD-like material and a polymer-based layer which is characterized as exhibiting flexibility. A first layer including a TMD-based material (e.g., an atomic-thick layer including TMD) or TMD-like material is provided or grown on a surface which in certain instances may be a rigid platform or substrate. A plurality of electrodes are provided on or as part of the first layer, and another layer or film including polymer is applied to cover the first layer and the electrodes. The other layer is integrated with the TMD material or TMD-like material and the first layer, and the other layer provides a flexible substrate such as when released from the exemplary rigid platform or substrate.

Abstract: Processes and materials to detect cancer from a biopsy are described. In some cases, cell-free nucleic acids can be sequenced, and the sequencing result can be utilized to detect sequences derived from a neoplasm. Detection of somatic variants occurring in phase can indicate the presence of cancer in a diagnostic scan and a clinical intervention can be performed.

Abstract: A series of carbohydrate-dye conjugates, as well as a method for detection of pathogenic or other organisms (e.g., bacteria) using the same are provided. The carbohydrate-dye conjugate can be enzymatically incorporated into live and active (viable) bacteria of interest for facile detection of said bacteria. The conjugate incorporation is achieved by utilizing one or more of the enzymes that are endogenous to the bacteria of interest, which can incorporate the conjugate via the conjugate's carbohydrate. A detectable signal is produced by the conjugate's dye only upon incorporation into the bacteria of interest, due to the changes in the dye's local environment upon incorporation. The conjugate may be metabolically incorporated into the fatty outer membrane of a bacterial cell wall, which provides a distinctly hydrophobic environment for the conjugate's dye, causing it to produce a detectable signal.

Abstract: Compounds and methods are provided for the treatment of pathogen infections. In some embodiments, the anti-infective compounds have broad spectrum activity against a variety of infective diseases, where the diseases are caused by pathogens containing a basic amino acid PIP-2 pincer (BAAPP) domain that interacts with phosphatidylinositol 4,5-bisphosphate (PIP-2) to mediate pathogen replication. Also provided are methods of inhibiting a PI4-kinase and methods of inhibiting viral infection. In some embodiments, the compound is a PI4-kinase inhibiting compound that is a 5-aryl-thiazole or a 5-heteroaryl-thiazole.

Abstract: A system and method for identifying and treating a disease in a patient collects one or more data streams from sensors configured to detect biological signals generated within a patient's tissue over time. Patient data elements including one or more of demographic, clinical, laboratory, pathology, chemical, image, historical, genetic, and activity data for the patient is collected and processed with the data streams to generate a personalized digital phenotype (PDP). The PDP is compared to a digital taxonomy comprising prior data to classify the patient into one or more quantitative disease classifications to guide personalized intervention for treating the patient.
