Publication number: 20220025454Abstract: The invention relates to a method for predicting mycobacterial drug resistance by isolating mycobacterial nucleic acid from a sample, obtaining a sample sequence from the nucleic acid, aligning and comparing the sample sequence to a reference sequence and determining for each reference position whether the sample sequence value is the same as a particular sequence value assigned to the position in a table. If both values are the same, a position weight value is assigned to the position. A predictor value is obtained by adding all position weight values and the predictor value is compared to a threshold value. If the predictor value is smaller than the threshold value, drug resistance is predicted. The invention encompasses a system for practicing the method, and the use of certain antibacterial drugs to treat infections by pathogens, resistance of which has been determined by the method of the invention.Type: ApplicationFiled: November 29, 2019Publication date: January 27, 2022Applicant: UNIVERSITÄT ZÜRICHInventors: Thorsten BUCH, Prajwal PRAJWAL, Sebastian DÜMCKE

Publication number: 20210219881Abstract: A spectrophotometric apparatus for determining optical parameters in a scattering medium based on the measurement of attenuation of light propagating through said medium by diffusion. To eliminate the detrimental effect of light being guided in an intermediate optical layer between a surface of the medium and a contact surface of the apparatus, either a multitude of optical barriers may be formed in the contact surface or the angular range over which light is emitted or received by the apparatus may be limited by appropriate means. With both of these alternative approaches, light propagation in the intermediate layer can be suppressed, leading to increased measurement accuracy. This is particularly beneficial for building an oximeter with improved precision. Further aspects include features for improving the applicability of the apparatus on curved surfaces such as the strongly curved skulls of neonates.Type: ApplicationFiled: October 19, 2018Publication date: July 22, 2021Applicant: Universitat ZurichInventors: Stefan KLEISER, Martin WOLF, Daniel OSTOJIC, Nassimsadat NASSERI
