Provided herein are methods and compositions for modulating the activity or level of a sirtuin, thereby treating or preventing obesity or an insulin resistance disorder, such as diabetes in a subject. Exemplary methods comprise contacting a cell with a sirtuin activating compound or an inhibitory compound to thereby increase or decrease fat accumulation, respectively.

The present invention generally relates to microfluidic devices, including methods and systems for tagging droplets within such devices. In some aspects, microfluidic droplets are manipulated by exposing the droplets (or other discrete entities) to a variety of different conditions. By incorporating into the droplets a plurality of nucleic acid tags, and optionally amplifying the nucleic acids, e.g., within the droplets, the conditions that a droplet was exposed to may be encoded by the nucleic acids. Thus, even if droplets exposed to different conditions are mixed together, the conditions that each droplet encountered may still be determined, for example, by sequencing the nucleic acids.


The disclosure relates to methods for treating a subject suffering from a burn injury or associated complications by administering to the subject an effective amount of an aromatic-cationic peptide. For example, a burn injury may be associated with distant pathophysiological effects, such as hypermetabolism, skeletal muscle dysfunction, and organ damage. The disclosure also relates to methods for protecting a subject from a burn injury by administering an effective amount of an aromatic-cationic peptide to a subject at risk of a burn injury.

Embodiments of the invention provide knee prostheses (100) which more faithfully and closely replicate the function, anatomy and physiology of the normal human knee yielding a number of advantages. Among other things, such prostheses can provide an increased range of motion and function more normally particularly in extension, deep flexion and during normal gait. Knee prostheses according to various aspects of the invention recognize that during movement of the knee, particularly during flexion, the kinematics of the bones of the knee are a result of achieving equilibrium of the forces that cause motion of the knee. In addition, the shape of the articular surfaces acting in combination with forces imposed by various muscles, ligaments and tendons, determines the direction of the large contact forces.

A magnetic resonance (MR) method and system are provided for generating real-time prospective motion-corrected images using fast navigators. The real-time motion correction is achieved by using a 2D EPI navigator that is obtained using a simultaneous multi-slice blipped-CAIPI technique. The navigator parameters such as field of view, voxel size, and matrix size can be selected to facilitate fast acquisition while providing information sufficient to detect rotational motions on the order of several degrees or more and translational motions on the order of several millimeters or more. The total time interval for obtaining and reconstructing navigator data, registering the navigator image, and providing feedback to correct for detected motion, can be on the order of about 100 ms or less. This prospective motion correction can be used with a wide range of MR imaging techniques where the pulse sequences do not have significant intervals of dead time.

The present disclosure relates to method of distinguishing between two or more species of one or more organisms in a sample, by contacting a biological sample comprising ribosomal ribonucleic acid (rRNA) with a set of antisense probes, wherein the set of probes contains at least one detectable probe that is specific for a target rRNA sequence of each species to be tested, and wherein the individual probes specific for each species comprises less than about 85% sequence identity; and, detecting hybridization between one or more of the probes and the rRNA, thereby distinguishing between two or more species in a sample.

The present invention relates to diagnostic, prognostic and clinical methods of distinguishing high-risk IPMN from more benign IPMN as well as high-grade PanIN and PDAC from low-grade PanIN with moderate sensitivity and very high specificity using Das-1 and related antibodies.

Methods and devices are provided for activating brown adipose tissue with targeted substance delivery. Generally, the methods and devices can activate BAT to increase thermogenesis, e.g., increase heat production in the patient, which over time can lead to weight loss and/or improved metabolic function. In one embodiment, a chemical configured to stimulate nerves that activate the BAT and/or to stimulate brown adipocytes directly can be delivered to a patient, thereby increasing thermogenesis in the BAT and inducing weight loss and/or improved metabolic function through energy expenditure. The chemical can be delivered to the patient locally and/or systemically to stimulate the nerves and/or the brown adipocytes.


Background Findings from family and twin studies suggest that genetic contributions to psychiatric disorders do not in all cases map to present diagnostic categories. We aimed to identify specifi c variants underlying genetic eff ects shared between the fi ve disorders in the Psychiatric Genomics Consortium: autism spectrum disorder, attention defi cit-hyperactivity disorder, bipolar disorder, major depressive disorder, and schizophrenia. Methods We analysed genome-wide single-nucleotide polymorphism (SNP) data for the fi ve disorders in 33 332 cases and 27 888 controls of European ancestory. To characterise allelic eff ects on each disorder, we applied a multinomial logistic regression procedure with model selection to identify the best-fi tting model of relations between genotype and phenotype. We examined cross-disorder eff ects of genome-wide signifi cant loci previously identifi ed for bipolar disorder and schizophrenia, and used polygenic risk-score analysis to examine such eff ects from a broader set of common variants. We undertook pathway analyses to establish the biological associations underlying genetic overlap for the fi ve disorders. We used enrichment analysis of expression quantitative trait loci (eQTL) data to assess whether SNPs with cross-disorder association were enriched for regulatory SNPs in post-mortem brain-tissue samples. Findings SNPs at four loci surpassed the cutoff for genome-wide signifi cance (p< 5×10-8) in the primary analysis: regions on chromosomes 3p21 and 10q24, and SNPs within two L-type voltage-gated calcium channel subunits, CACNA1C and CACNB2. Model selection analysis supported eff ects of these loci for several disorders. Loci previously associated with bipolar disorder or schizophrenia had variable diagnostic specifi city. Polygenic risk scores showed cross-disorder associations, notably between adult-onset disorders. Pathway analysis supported a role for calcium channel signalling genes for all fi ve disorders. Finally, SNPs with evidence of cross-disorder association were enriched for brain eQTL markers. Interpretation Our fi ndings show that specifi c SNPs are associated with a range of psychiatric disorders of childhood onset or adult onset. In particular, variation in calcium-channel activity genes seems to have pleiotropic eff ects on psychopathology. These results provide evidence relevant to the goal of moving beyond descriptive syndromes in psychiatry, and towards a nosology informed by disease cause.
