  • Patent number: 10667718
    Abstract: Example embodiments associated with characterizing a sample using NMR fingerprinting are described. One example NMR apparatus includes an NMR logic that repetitively and variably samples a (k, t, E) space associated with an object to acquire a set of NMR signals that are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. The NMR apparatus may also include a signal logic that produces an NMR signal evolution from the NMR signals and a characterization logic that characterizes a tissue in the object as a result of comparing acquired signals to reference signals. Example embodiments facilitate distinguishing prostate cancer tissue from normal peripheral zone tissue based on quantitative data acquired using NMR fingerprinting in combination with apparent diffusion co-efficient (ADC) values or perfusion values acquired using DWI-MRI or DCE-MRI.

  • Patent number: 10662164
    Abstract: The invention provides a newly discovered oxadiazole class of antibiotics. The oxadiazoles impair cell-wall biosynthesis and exhibit activities against the Gram-positive bacteria such as the bacterium Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA) and vancomycin-resistant and linezolid-resistant S. aureus. For example, 5-(1H-indol-5-yl)-3-(4-(4-(trifluoromethyl)phenoxy)phenyl)-1,2,4-oxadiazole (antibiotic 75b) was efficacious in a mouse model of MRSA infection, exhibiting a long half-life, a high volume of distribution, and low clearance. Antibiotic 75b antibiotic is bactericidal and is orally bioavailable. This class of antibiotics can be used as a therapeutic agent against infections by Gram-positive bacteria such as MRSA.

  • Patent number: 9709511
    Abstract: Apparatus, system, method and computer-readable medium for isolating chemical exchange saturation transfer contrast from magnetization transfer asymmetry under two-frequency RF irradiation. A two-pool model for magnetization transfer (MT) can be established fully based on Provotorov's theory of saturation, and then extended to the situation of simultaneous two-frequency RF irradiation. Numerical simulations and experimental results demonstrate that two-frequency RF irradiation can make MT effects independent of irradiation frequency over a wide range, and thus can suppress MT asymmetry. Exemplary embodiments can be provided to isolate chemical exchange saturation transfer (CEST) contrast from MT asymmetry contrast by using the two-frequency RF irradiation technique. A further embodiment can isolate a narrow-frequency spectrum MT mechanism from a broad-frequency spectrum MT mechanism.

  • Patent number: 9702946
    Abstract: Parahydrogen Induced Polarization was employed to prepare nuclear singlet state between methylene and methyl protons in propane gas. Low-field MRI preserves this singlet state with much longer TS=4.7±0.5 s. Spin-Lock Induced Crossing (SLIC) transforms singlet state in observable nuclear magnetization suitable for MRI with sub-millimeter and sub-second spatial and temporal resolution respectively with signal enhancement>10,000 times. Long-lived spin states created in hyperpolarized propane-d6 gas can be detected directly at 0.0475 T. This long lifetime and non-toxic nature of propane gas could be useful for bio-imaging applications including potentially pulmonary low-field MRI. The feasibility of high-resolution low-field 2D gradient-echo MRI was demonstrated with 0.88×0.88 mm2 spatial and ˜0.7 s temporal resolution respectively at 0.0475 T. Propane is a non-toxic gas, and therefore, these results enable low-cost high-resolution high-speed MRI of gases for imaging of lungs.

  • Patent number: 9327024
    Abstract: [Object] To provide a polymer coated ferrite fine particles being possible to control a particle size uniformly while having high aqueous dispersibility and preferred biomolecule immobilization ability and an easy method for preparing the same. [Means Addressing Object] In an aqueous solvent, iron ion is protected by chelating polyacrylic acid and then alkaline is added. Thereafter, a reaction system is heated under pressurized condition to produce simultaneous precipitation of the ferrite fine particles and coating thereof. As the result, the polymer coated ferrite fine particles having uniform particle size may be prepared in one step with excellent reproducibility. The polymer coated ferrite fine particles of the present invention has high water dispersibility and has preferred biomolecule immobilization performance by carboxyl groups coming from the polyacrylic acid.

  • Patent number: 9329246
    Abstract: A method for producing a hyperpolarized sample for use in a magnetic resonance investigation has the following steps: a) providing a solid sample (50), containing long T1 nuclei and short T1 nuclei in the same molecules (51); b) hyperpolarizing the short T1 nuclei in the solid sample (50); c) transforming the solid sample (50) into a liquid sample (52); and d) transferring the polarization of the short T1 nuclei to the long T1 nuclei within the molecules in the liquid sample (52) by Cross Polarization. The method can provide samples with hyperpolarized long T1 nuclei, in particular 13C or 15N, in a simple and efficient way.

  • Patent number: 9289518
    Abstract: A method of preparing a hydrogen-containing 13C compound test sample exhibiting an enhanced 13C nuclear magnetic resonance (NMR) signal when exposed to a 13C NMR pulse sequence is disclosed. In the disclosed method, the hydrogen-containing 13C compound is mixed with hyperpolarized 129Xe in the gaseous state, and the mixture is subsequently frozen within a magnetic field. The magnetic field strength is then reduced sufficiently so that spin polarization is transferred from the hyperpolarized 129Xe to the compound. The magnetic field strength is then increased, and the mixture is thawed to obtain the test sample.
