Abstract: The present invention relates to methods and pharmaceutical compositions useful for the treatment of hyperglycemia. Thorough multiple analyses, inventors demonstrated that Gfi1 is expressed in pancreatic acinar cells, starting from the first stages of pancreatic embryonic development. Furthermore, they observed that Gfi1 mRNA levels remain steady throughout embryonic development, while they significantly increase during the first days of life. They challenged conditional mutant mice with high fat diet for 5 months and monitored their weight and glycemia weekly. All the animals displayed a rapid increase in body mass as expected. While control mice rapidly developed a massive hyperglycemia, mutant mice remained normoglycemic throughout the entire experiment. A similar protection from induced diabetes was observed upon treatment with a high dose of Streptozotocin.

Abstract: A method and system for secure ultrasound treatment of living tissues using an ultrasound probe comprising a reflective cavity in acoustic communication with living tissues, a transducer to emit an ultrasound wave in the reflective cavity and a transducer to acquire a backscattered signal in the reflective cavity. The method comprises the steps of a) emitting a first ultrasound wave in the reflective cavity that generates a backscattered ultrasound wave in the reflective cavity, b) acquiring a backscattered signal in the reflective cavity, c) determining whether an insonification can be safely performed by computing a similarity value between the backscattered signal and a predefined reference signal, and d) if an insonification can be safely performed, treating the living tissues with a second ultrasound wave emitted in the reflective cavity. The second ultrasound wave is focused a target point of the living tissues and generates a pressure point resulting in cavitation at this target point.

Abstract: According to the invention, n incident acoustic waves Ei(t), obtained by linearly combining n elemental incident waves E0i(t) with an encoding matrix Hc are consecutively transmitted in a medium to be imaged. n reverberated waves Ri(t) from the medium to be imaged are then consecutively detected, following the transmission of the n incident waves; then n elemental reverberated waves R0i(t) are determined by linearly combining the detected n reverberated waves Ri(t) with a decoding matrix Hd. The Hc and Hd matrices are such that Hc·Hd=D, where D is a diagonal matrix of order n, all the diagonal elements of which are greater than 1.
