Abstract: Methods for making particles, such as nanoparticles, devices useful in the methods, and particles made by the method are described herein. The methods involves the use of microfluidic device, such that upon mixing solutions of the materials to form the particles (or a solution of the material or materials to form the particles and a non-solvent for the material or materials) at least two symmetrical microvortices are formed simultaneously. The method can be used to prepare polymeric or non-polymeric particles and hybrid particles, such as lipid-polymer hybrid particles, as well as such particles containing one or more agents associated with the particles.

Abstract: The invention relates to therapeutic nanobiologic compositions and methods of treating patients who have had an organ transplant, or who suffer from atherosclerosis, arthritis, inflammatory bowel disease including Crohn's, autoimmune diseases including diabetes, and/or autoinflammatory conditions, or after a cardiovascular events, including stroke and myocardial infarction, by inhibiting trained immunity, which is the long-term increased responsiveness, the result of metabolic and epigenetic re-wiring of myeloid cells and their stem cells and progenitors in the bone marrow and spleen and blood induced by a primary insult, and characterized by increased cytokine excretion after re-stimulation with one or multiple secondary stimuli.

Abstract: Presented herein are methods and compositions for non-invasive imaging of TAMs with discoidal high-density lipoproteins to assess prognosis and therapy outcome. TAMs are increasingly investigated in cancer immunology, and are considered a promising target for better and tailored treatment of malignant growths. Although TAMs also have high diagnostic and prognostic value, TAM imaging still remains largely unexplored. Imaging agents/methods provided herein are of value for non-invasive in vivo evaluation of TAM burden, not only in preclinical but also in clinical settings.

Abstract: Described herein is a non-invasive quantitative positron emission tomography (PET) nanoreporter technology that allows personalized therapeutic outcome prediction. In a breast cancer mouse model, it was demonstrated that co-injecting Doxil and a Zirconium-89 nanoreporter (89Zr-NRep) enabled highly precise doxorubicin (DOX) quantification. Imaging 89Zr-NRep via PET revealed remarkable Doxil accumulation heterogeneity independent of tumor size.

Abstract: The present invention is directed to synthetic nanoparticles useful as imaging agents for use in MRI, CT, Gamma-scintigraphy, or optical imaging techniques. The synthetic nanoparticles comprise at least one apolipoprotein that is not an apoB lipoprotein, at least one amphipathic lipid, and at least one metallic or non-metallic contrast agent linked through a chelator to a component of the nanoparticle, wherein the one metallic or non-metallic contrast agent is present in an amount of between 5% to about 50% (w/w) of the nanoparticle, and the nanoparticle has a diameter of from about 5 nm to about 50 nm. Compositions and kits comprising the synthetic nanoparticles and methods of making and using the same are also provided.

Abstract: The present invention also provides methods and compositions for imaging and evaluating, e.g., blood flow or inflammation in a subject. Such evaluations are important in a number of clinical diagnoses, including assessing organ damage associated with angina pectoris, heart attack, stroke, cancer, atherosclerosis, and the like, as well as assessing vessel leakages associated with aneurisms, diffuse bleedings after trauma, and the like.

Abstract: The invention provides a use of a long-circulating microvesicle comprising a sterol, partially synthetic or wholly synthetic vesicle-forming phospholipids, and a corticosteroid in water soluble form, which microvesicle has a mean particle diameter size range of between about 75 and 150 nm and which microvesicle is non-charged or negatively charged at physiological conditions, for the preparation of a medicament for the treatment of atherosclerosis and/or cardiovascular disease. A method for treating a subject suffering from, or at risk of suffering from, atherosclerosis and/or cardiovascular disease, comprising administering to said subject a therapeutically effective amount of such long-circulating microvesicles is also provided.

Abstract: A multicontrast-weighted acquisition of three images is performed with an MRI system. Each image is normalized and then mapped to a separate color channel. A composite color image is formed by combining all the color channels, and this image is displayed or analyzed to identify different tissue types therein.

Abstract: The invention includes a technique for efficient multi-slice fast spin echo image acquisition with black blood contrast in cardiac imaging. The technique includes applying a non-selective inversion pulse, followed by a re-inversion pulse that is slice-selective over a region encompassing a plurality of slice selections. Execution of a series of RF excitation pulses with fast spin echo readout is timed such that signal from blood is near a null point before acquiring data for each spatial slice. For greater contrast consistency, the flip angles for the excitation pulses occurring before the null point can be reduced, and those occurring after the null point can be increased.

Abstract: DIR imaging of blood vessels by administering a series of DIR preparation pulse modules at a repetition interval short enough that at least two DIR preparation pulse modules generally occur within each RR interval, and by acquiring image data for a plurality of slices following each DIR module.
