Abstract

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.

Abstract

Functional imaging, in particular functional ultrasound imaging, is becoming a powerful tool for early detection of disorders such as neurodegenerative diseases. The present disclosure proposes a reliable method for such early detection, by delivering a stimulus to the nervous system, performing a functional imaging of an area of interest of the nervous system activated by the stimulus to obtain a series of hemodynamic Doppler images of the vascular network in the area of interest, and computing, from the series of hemodynamic Doppler images, a hemodynamic response (22) to the stimulus. The shape of hemodynamic response may be used to detect health disorders.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

The invention relates to the identification of a new Tau species starting at residue Met11 (Met11-Tau) which is N-alpha-terminally acetylated form (N-alpha-acetyl-Met11-Tau species: Ac-Met11-Tau). Several monoclonal antibodies specific of this new Tau species have been developed. One of this antibody, 2H2/D11, was used in THY-Tau22 mouse model (that develops with age neurofibrillary degeneration (NFD) and memory deficits), and N-alpha-Ac-Met11-Tau species were clearly detected early in neurons displaying NFD on hippocampal brain sections while it is not reactive in hippocampus from elderly controls. Finally, by using ELISA sandwich specific of Ac-Met11-Tau species, Alzheimer Disease (AD) brain samples are clearly discriminated from human elderly control brains. Thus the invention relates to this new Tau species starting from the methionine residue at position 11 said methionine being N-alpha acetylated. The invention also relates to antibody that specifically binds this new tau species, a method of detection of this new Tau species and a method of diagnosis of Tauopathy disorder.

Abstract

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 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.
