Abstract:
The present invention relates to a method for the acetylation of an aqueous solution of lactic acid to (S)-2-acetyloxypropionic acid.The process comprises in particular removing water from the solution of lactic acid and reacting lactic acid with acetic anhydride in the presence of acetic acid.
Abstract:
The present invention relates to the use of a NIR fluorescent probe comprising an aza-bicycloalkane based cyclic peptide labelled with a Cy5.5 dye moiety in the fluorescence- guided surgery of pathologic regions and to an optical imaging method that comprises using this fluorescent probe for the identification and demarcation of tumor margins during the surgical resection.
Abstract:
The present invention relates to a new class of diazepine-derivatives as chelating agents for paramagnetic metal ions, the process for their preparation, and use of such paramagnetic complexes as contrast agents, particularly suitable for Magnetic Resonance Imaging (MRI) analysis. The present invention refers to a new class of derivatives of formula (I), or a pharmaceutically acceptable salt thereof.
Abstract:
A fluid delivery system may include a container that houses a medical fluid, a fluid pressurizing unit, and a fluid transfer set that transfers the medical fluid from the container to the fluid pressurizing unit. To validate the integrity and sterility of the fluid delivery system, the system may undergo testing protocols to evaluate the susceptibility of the system to pathogenic ingress, chemical degradation, and/or fluid cross-contamination between patient fluid delivery procedures. The testing protocols may help ensure that delivery system components used during multiple different fluid delivery procedures perform as well as if the components were replaced after each fluid delivery procedure.

Abstract:
The present invention relates to the field of optical imaging. More particularly, it relates to compounds of the cyanine family with near-infrared emission characterized by improved physico-chemical and biological properties and to conjugates with biological ligands thereof. The invention also relates to the use of these compounds as optical diagnostic agents in imaging or therapy of solid tumors, to the methods for their preparation and to the compositions comprising them.
Abstract:
A solution is proposed for training a machine learning model (420) for use in medical imaging applications. A corresponding method (700) comprises providing (703-743: 759-763) sample sets, each comprising a sample baseline image, a sample target image (acquired from a corresponding body-part of a subject to which a contrast agent at a certain dose has been administered) and a sample source dose (corresponding to a different dose of the contrast agent). The machine learning model (420) is trained (744-758) so as to optimize its capability of generating each sample target image from the corresponding sample baseline image and sample source image. One or more of the sample sets are incomplete, missing their sample source images. Each incomplete sample set is completed (704-742: 759-763) by simulating the sample source image from at least the sample baseline image and the sample target image of the sample set. A computer programs (500) and a computer program products for implementing the method (700) are proposed. Moreover, a computing system (130) for performing the method (700) is proposed.
