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.

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.

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.

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.

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.

Method for imaging vascular activity dynamically at a microscopic scale in a vascular network of a human or animal, the method including: (a) performing a temporal series of Ultrasound Localization Microscopy images of a region of the vascular network, to obtain values of a vascular dynamics parameter in an area of interest in the region, a recording period of the temporal series of ULM images corresponding to a dynamical event, due to a cause other than cardiac pulsatily, which activates the vascular network in the region; (b) computing, based on the values of the vascular dynamics parameter, a measure of an evolution of the vascular dynamics parameter in response to the dynamical event.

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.

The present invention relates, inter alia, to the use of porous crystalline solids constituted of a metal-organic framework (MOF) for the selective capture of volatile organic compounds (VOCs) comprising carboxylic acid functional group(s) and/or volatile organic compounds (VOCs) comprising an hydroxyl functional group. The MOF solids of the present invention can be used for the purification of air, for example for the selective capture of VOCs comprising carboxylic acid functional group(s) and/or volatile organic compounds (VOCs) comprising an hydroxyl functional group from outdoor air. It may be used for art preservation, such as the conservation of cellulose derivate films, for indoor air purification systems such as HERA air filters, adsorbent purifiers, kettle filters, fette filters, honeycomb filters or air conditioning filters, for outdoor air purification systems such as gas mask, nose filter, adsorption columns or chimney filters, and in cosmetic applications such as deodorants, anti-odor shampoo, hygienic protection products, wipes or diapers.
