Abstract:
Inhalable compositions are described. The inhalable compositions comprise one or more respirable aggregates, the respirable aggregates comprising one or more poorly water soluble active agents, wherein at least one of the active agents reaches a maximum lung concentration (C max ) of at least about 0.25 μg/gram of lung tissue and remains at such concentration for a period of at least one hour after being delivered to the lung. Methods for making such compositions and methods for using such compositions are also disclosed.
Abstract:
The present invention provides an isolated nucleic acid encoding a novel lactate dehydrogenase (LDH) as well as the isolated LDH polypeptide. Also provided are methods of enhancing fuel-stimulated insulin secretion, in particular, glucose-stimulated insulin secretion. Further provided are methods of screening for compounds that bind LDH, modulate LDH activity, and/or modulate fuel- or glucose-stimulated insulin secretion and the compounds identified thereby. The invention further provides a method of enhancing insulin secretion by administering a nucleic acid encoding LDH to a subject in a therapeutically effective amount.
Abstract:
The present invention provides nucleic acids encoding a novel ABC family cholesterol transporter, ABCG8. The herein-disclosed sequences can be used for any of a number of purposes, including for the diagnosis and treatment of cholesterol-associated disorders, including sitosterolemia, and for the identification of molecules that associate with and/or modulate the activity of ABCG8.
Abstract:
Prion peptides exhibiting structural isomerism to wild-type prion peptide are disclosed. The invention further discloses methods of making prion isomers, compositions comprising prion isomers, and compositions and products comprising antibody to a prion isomer. Methods for screening a patient for a neuro-degenerative disease, and methods for treating a patient afflicted with a neuro-degenerative disease are also disclosed.
Abstract:
A method for preparing poorly water soluble drug particles is disclosed. The method comprises dissolving a drug in at least one organic solvent to form a drug/organic mixture, spraying the drug/organic mixture into an aqueous solution and concurrently evaporating the organic solvent in the presence of the aqueous solution to form an aqueous dispersion of the drug particles. The resulting drug particles are in the nanometer to micrometer size range and show enhanced dissolution rates and reduced crystallinity when compared to the unprocessed drug.
Abstract:
The invention relates to liposomal formulations containing a rifamycin and/or a hydrophobic derivative as a pharmacological active substance, for clinical use, comprising pharmacological active substance/lipid ratios of 1 mole per 10 to 40 moles, lipidic compositions made by mixtures of glycerophospholipids of saturated or unsaturated acyl chains, with cholesterol and charged molecules of lipidic nature or not. The liposomal rifamycin presents a stability in saline and in human serum higher than 50 %, incorporation efficiencies up to 95 %, intraliposomal concentration of at least 1 mg/ml and toxicity lower compared to the free pharmacological active substance. The invention also refers to a process for the preparation of liposomal formulations comprising solving the pharmacological active substance and the other components in appropriate solvents, lyophilization or not and rehydration of the lyophilized or resulting mixture.
Abstract:
A method and system for generating a treatment plan are disclosed herein. A computing system receives a plurality of dose volume histograms for a plurality of patients and a plurality of volumetric dose distributions corresponding to the plurality of dose volume histograms. The computing system generates a volumetric dose prediction model using a neural network by learning, by the neural network, a relationship between a plurality of dose volume histograms for the plurality of patients and the corresponding plurality of volumetric dose distributions. The computing system receives a candidate dose volume histogram for a target patient. The computing system infers, via the volumetric dose prediction module, a volumetric dose prediction distribution matching the candidate dose volume histogram. The computing system generates a recommendation based on the inferred volumetric dose prediction distribution.
Abstract:
The present disclosure relates to heterocyclic compounds and methods which may be useful as inhibitors of ATR kinase for the treatment or prevention of cancer.
Abstract:
Open tubular capillary columns for liquid and ion chromatography, based upon an ionically impermeable polyolefin capillary having a bore with a sulfonate-group- or amine- group-functionalized internal surface. The capillary columns may include a coating of ion exchanging nanoparticles electrostatically bound to the functionalized internal surface. The capillary columns may be made by exposing the interior surface to a sulfonating reagent comprising chlorosulfonic acid (CIS03H), preferably from 85 wt% to 95 wt% chlorosulfonic acid at a process temperature of 20 to 25 °C. The interior surface may be subsequently exposed to an asymmetrical diamine to form a sulfonic mid-linkage to the diamine, i.e., to form a sulfonamide-linked, amine-group-functionalized internal surface. The coating may be provided by subsequently exposing the interior surface to an aqueous suspension of ion exchanging nanoparticles to electrostatically bond the ion exchanging nanoparticles to the functionalized internal surface.
Abstract:
Described herein are methods and system that use electromagnetic heating to heat wellbores and the fluids therein. The heating is achieved by placing one or more permanent magnets in the wellbore and moving a metallic component and/or the one or more permanent magnets relative to each other. This generates eddy currents in the metallic component, which heat the metallic component. This heat is transferred to the fluids in the wellbore from the metallic component by convection. In some embodiments, permanent magnets are installed in the tubing to induce eddy current heating in a well by converting the linear motion of a sucker rod to rotary motion of a conducting tube using a lead or ball screw. The heater may directly integrate with existing pump jack equipment with little or no additional infrastructure required.
