  • Publication number: 20190254624
    Abstract: Imaging of internal structure of a patient, such as the prostate, is performed using ultrasound tomography by inserting a first ultrasound probe into the rectum of the patient, positioning a second ultrasound probe on an abdomen of the patient, and aligning the first and second ultrasound probes with one another to obtain acoustic information for reconstructing tomographic images of the internal structure. Light sources can also be shined to the tissue of interest, such as prostate say by a transurethral catheter thus making photoacoustic waves that can be received by the said TRUS or TRAB/TRPR transducers to reconstruct photoacoustic tomographic image of the tissue, as well.

  • Publication number: 20190256920
    Abstract: More than 2% of adults harbor a pancreatic cyst, a subset of which progress to invasive lesions with lethal consequences. To assess the genomic landscapes of neoplastic cysts of the pancreas, we determined the exomic sequences of DNA from the neoplastic epithelium of eight surgically resected cysts of each of the major neoplastic cyst types: serous cystadenomas (SCAs), intraductal papillary mucinous neoplasms (IPMNs), mucinous cystic neoplasms (MCNs) and solid pseudo-papillary neoplasms (SPNs). SPNs are low-grade malignancies, and IPMNs and MCNs, but not SCAs, have the capacity to progress to cancer. We found that SCAs, IPMNs, MCNs, and SPNs contained 10=4.6, 27=12, 16=7.6, and 2.9=2.1 somatic mutations per tumor, respectively. Among the mutations identified, E3 ubiquitin ligase components were of particular note. Four of the eight SCAs contained mutations of VHL, a key component of the VHL ubiquitin ligase complex that has previously been associated both with renal cell carcinomas, SCAs, and other neoplasms.

  • Patent number: 10385332
    Abstract: The present invention is based, at least in part, on the development of a mating-based yeast two-hybrid screen that allows simultaneous screening for mutations that disrupt yeast two-hybrid interactions between a protein and multiple interacting partners. By coupling PCR mutagenesis and homologous recombination/gapped plasmid repair with a mating-based assay, the present invention allows screening for unique mutations that disrupt interaction with one partner, but not others. It also allows identification of specific mutations that may lie at protein-protein interfaces common to two or more partners, without employing multiple rounds of screening. In addition to screening against multiple interacting partners, the present invention removes the need for a two-step selection because truncations, frameshifts, or any mutations that affect folding are eliminated as disruptions that affect all protein partners.

  • Patent number: 10376682
    Abstract: Implantable pressure-actuated systems to deliver a drug and/or other substance in response to a pressure difference between a system cavity and an exterior environment, and methods of fabrication and use. A pressure-rupturable membrane diaphragm may be tuned to rupture at a desired rupture threshold, rupture site, with a desired rupture pattern, and/or within a desired rupture time. Tuning may include material selection, thickness control, surface patterning, substrate support patterning. The cavity may be pressurized above or evacuated below the rupture threshold, and a diaphragm-protective layer may be provided to prevent premature rupture in an ambient environment and to dissipate within an implant environment. A drug delivery system may be implemented within a stent to release a substance upon a decrease in blood pressure. The cavity may include a thrombolytic drug to or other substance to treat a blood clot.

  • Patent number: 10368956
    Abstract: An embodiment in accordance with the present invention provides a technique for localizing structures of interest in projection images (e.g., x-ray projection radiographs or fluoroscopy) based on structures defined in a preoperative 3D image (e.g., MR or CT). Applications include, but are not limited to, spinal interventions. The present invention achieves 3D-2D image registration (and particularly allowing use with a preoperative MR image) by segmenting the structures of interest in the preoperative 3D image and generating a simulated projection of the segmented structures to be aligned with the 2D projection image. Other applications include various clinical scenarios involving 3D-2D image registration, such as image-guided cranial neurosurgery, orthopedic surgery, biopsy, and radiation therapy.

  • Patent number: 10369124
    Abstract: The treatment of many ocular disorders is hampered because of poor penetration of systemically administered drugs into the eye. The tight junctional complexes (zonulae occludens) of the retinal pigment epithelium and retinal capillaries are the site of the blood-ocular barrier. This barrier inhibits penetration of substances, including antibiotics, into the vitreous. Over the last 18 years we have evaluated the nontoxic doses of various drugs. These include antibiotics and antifungals for treatment of bacterial and fungal endophthalmitis, antivirals for treatment of viral retinitis (specifically, when medication with these drugs poses the threat of toxicity to other organs). Intravitreal antineoplastic drugs have been studied to prevent cell proliferation in the vitreous cavity after retinal attachment surgery, which can lead to proliferative vitreoretinopathy (PVR).

  • Patent number: 10369113
    Abstract: The invention provides a nanoparticle composition that is decorated with a urea-based small-molecule peptidomimetic inhibitor of prostate specific membrane antigen (PSMA), which is expressed by almost all solid tumors. This strategy takes advantage of both the avidity of the functionalized nanoparticle for binding to PSMA and the ability of the nanoparticle to be retained for longer periods of time in the tumor due to enhanced leakage via EPR into the tumor interstitium and poor clearance due to underdeveloped or non-existent lymphatics within the tumor.

  • Patent number: 10368720
    Abstract: A system for stereo reconstruction from a monoscopic endoscope includes an image pick-up element at a distal end thereof and a working channel defined by a body of the monoscopic endoscope. The system comprises a light patterning component configured to be disposed within the working channel such that a light emitting end of the light patterning component will be fixed with a defined relative distance from the distal end of the image pick-up element. The system also includes a data processor adapted to be in communication with the image pick-up element. The light patterning component forms a pattern of light that is projected onto a region of interest. The data processor receives an image signal of the region of interest that includes the pattern, and determines a distance from the endoscope to the region of interest based on the image signal and based on the defined relative distance.

  • Patent number: 10368753
    Abstract: An embodiment in accordance with the present invention provides a system and method for determining cardiac events. The system and method include using an imaging modality to obtain a cardiac image of the subject. The image is then used to determine the subject's systolic, post-systolic, and early diastolic strain peaks. Additionally, a strain rate index (SRI) value is computed for the subject using the systolic, post-systolic, and early diastolic strain peaks. The SRI value can then be used to determine a level of risk of cardiac failure. Further, a likelihood of atrial fibrillation can also be determined. The SRI value and risk of cardiac event can then be used to create a treatment plan for the subject, if necessary.
