Despite the notion that human CD8+ T cells are the final mediators of autoimmune β-cell destruction in type 1 diabetes (T1D), none of their target epitopes has been demonstrated to be naturally processed and presented by β cells. The inventors therefore performed an epitope discovery study combining HLA Class I peptidomics and transcriptomics strategies. Inflammatory cytokines increased β-cell peptide presentation in vitro, paralleling upregulation of HLA Class I expression. Peptide sources included known β-cell antigens and several insulin granule proteins. Urocortin 3 was identified as a novel β-cell antigen, which was processed into HLA-A2-and HLA-A3-restricted epitopes recognized by circulating naïve CD8+ T cells in type 1 diabetic and healthy donors. Accordingly, the present invention relates to antigenic peptides derived from urocortin-3 and uses thereof for the diagnosis and treatment of T1D.

While 3D ultrasound imaging is becoming a powerful tool in medical field. the main drawback is the difficulty to image large 3D volume. mainly related to the dimensions of the 2D array of transducers. In order to not lose in spatial resolution, it is necessary to use an array of transducers. wherein the size of the transducers does not exceed the wavelength of the ultrasound wave. Such requirement leads to dimensions of array for imaging large 3D volume which are not reachable or at too high cost with the current technology. The present disclosure overcomes the above technology limitation by using greater transducers, and where each transducer has a reception surface with a curved shape or is fitted with an acoustic lens. Such configuration of transducers leads to 2D array of transducers suitable for imaging large 3D volume, as a brain or a heart. with high resolution and high sensitivity.

Nowadays, the interest to use ultrasound waves in medical field is well established. Such ultrasound waves may be focused for treating a zone in an organ such as the brain for instance. The focus allows to treat only the zone relative to the disease and avoid treating a healthy zone. Therefore, it is mandatory to use an image guidance system to monitor in real time where the ultrasound waves are focused. The guidance can be performed by Magnetic Resonance Imaging (MRI), Ultrasound Imaging (echography), or Optical Imaging (neuronavigation). However, such systems increase the cost and the complexity of the whole process. The present disclosure overcomes the above drawbacks by proposing a self-positioning acoustic lens allowing to ensure good ultrasound waves transmission in the zone to treat without requiring to the use of a navigation system.

Nowadays, the interest to use ultrasound waves in medical field is well established. Indeed, the study of mechanical waves propagating in a medium allows usually to retrieve the properties of this medium as an organ such the heart. These elastic properties may be determined on the basis of propagation parameters as the velocity of shear waves propagating in the medium. The shear waves may be generated artificially or naturally (e.g. valves closure of the heart) in the medium. In both cases, the generation or/and observation of such shear waves require high complex and cost system as well as complex method for estimating with high precision the velocity of shear. The present disclosure overcomes the above drawbacks by proposing a new method and detection system for estimating in a simple and efficiency way the velocity of shear waves propagating in a medium, and with a high precision, requirement needed for determining the elastic properties of the medium.

Organ transplantation remains the only definitive therapeutic solution for many pathologies, but the number of currently available grafts is largely insufficient. A new approach is proposed to quantitatively evaluate isolated organs by ultrasound, which enables to safely admit more isolated organs as grafts available for transplantation. The isolated organ (2) is received in an organ preservation container (3) made of ultrasound transparent material, and the isolated organ is imaged by an ultrasound imaging probe (6) through the container (3). The ultrasound image of the isolated organ is used to determine a quantitative index representing viability of the isolated organ.

The present invention relates to the field of ultrasounds and imagining of the coronary blood flow of the heart. Patients with coronary microvascular dysfunction (CMD) have poor prognostic with significantly higher rates of cardiovascular events, including hospitalization for heart failure, sudden cardiac death, and myocardial infarction (MI). Despite the urgent clinical need, there are no non-ionizing and non-invasive techniques available in clinic to directly visualize the coronary microvasculature and assess the local coronary microvascular system. Flow imaging remains a difficult task to perform in the heart because of the fast movements of this organ. In order to overcome the limitations of actual imaging methods for the coronary blood flow, the inventors proposed an ultrasound ultrafast imaging method that automatically detect the time periods in which the myocardium velocity is low and estimate the coronary flow velocity and the tissue velocity from the same data acquisition.

Thin elastic films that can spontaneously attach to liquid interfaces, thereby offering a platform for tailoring their physical, chemical, and optical properties. Curved shells can be used to manipulate interfaces in qualitatively different ways. For example, an ultrathin shell with vanishing bending rigidity can impose its own rest shape on a liquid surface, in a process where the pressure across the interface inflates the shell into its original shape. The approach is amenable to optical applications as the shell is transparent, free of wrinkles, and may be manufactured over a range of curvatures.

The present description relates to a three-dimensional imaging system (100) comprising a light source (110) configured to emit a beam of spatially incoherent light, having a given central length, configured to illuminate a biological sample (10) being transmitted; an optical imaging system (120) comprising a microscope lens (121) with a given object focal plane (125) near which the sample (10) is positioned; means for axially moving the microscope lens relative to the sample; a two-dimensional acquisition device (140) comprising a plurality of elementary detectors arranged in a detection plane (141) optically conjugate with the object focal plane and a processing unit (150). For each section of a biological object of the sample, a plurality of two-dimensional interferometric signals resulting from optical interference between the illumination beam and a beam scattered by an object field of the section are acquired and at least a first image is calculated from the plurality of two-dimensional interferometric signals.

Because of the increase of the obesity related diseases, it is desirable to be able to detect a fatty liver and quantify the content in fat for the fatty liver. Known methods are biopsy and magnetic resonance imaging. However, biopsy is an invasive method and magnetic resonance imaging is a complicated method to carry out. The inventors propose a new ultrasonic method, which is more compliant with a regular control of the content in fat for the fatty liver for a subject. This method notably relies on a smart exploitation of the coherence properties of ultrasound pulses applied to the liver. This method has already been validated on sane subjects as providing accurate measurements, notably for fat content.

The structure (10) comprises an elastically deformable body (12) defining at least one network of internal cavities (14), each internal cavity (14) having a closed contour in at least one section of the internal cavity (14). Each internal cavity (14) is able to be pressurized so as to make the elastically deformable body (12) pass from a rest configuration to at least one pressurized configuration. In each pressurized configuration, the elastically deformable body (12) has a macroscopic metric that is distinct from its macroscopic metric in the rest position. In each pressurized configuration, the radius of curvature of an outer surface of the elastically deformable body (12), considered regarding each internal cavity (14) adjacent to the outer surface, is greater than twice the size of the internal cavity (14) adjacent to the outer surface.
