Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).

Project description:Meningitis is a complex disease which can be caused by infection with either viral or bacterial pathogens. Viral meningitis is usually a sterile self-limiting disease with a good clinical prognosis, while bacterial meningitis is a potentially more serious disease with a higher mortality rate. Early diagnosis of bacterial meningitis is of paramount importance, as intervention with antimicrobial therapy increases the likelihood of a favourable clinical outcome. Routine diagnosis in many laboratories is still dependent to some degree on traditional methods e.g. culture, though molecular methods have been developed which can give a shorter time to diagnosis. However, there is not as yet a single test format that can detect all bacterial pathogens capable of causing meningitis. In addition, many tests e.g. real-time PCR have a finite limit for multiplexing and do not provide additional information such as strain or serogroup which is useful during outbreaks and for retrospective epidemiological surveillance. To this end we have developed a microarray probe set for detection of meningitis-associated bacterial pathogens including those in the N. meningitidis serogroups. Here we demonstrate utility of this array in specific detection of represented bacterial species and strains and in detection of pathogen signals in cerebrospinal fluid samples from patients with suspected bacterial meningitis. This method shows promise for development as a diagnostic tool; however, we discuss the technical issues encountered and suggest mechanisms to improve resolution of pathogen-specific signals in complex clinical samples.

We designed as part of a larger pan-pathogen microarray a sub-set of probes to meningitis-associated bacterial pathogens. We present here data confirming the pathogen-specificity of many of these probes and their potential use in clinical diagnosis through testing on a small number of patient clinical samples using human DNA and no added nucleic acid controls. These data are from single channel Cy3-labelled nucleic acids. Four technical replicates for each feature are included on the array.

Project description:With its 2.5 Mb DNA genome packed in amphora-shaped particles of bacterium-like dimension (1.2 µm in length, 0.5 µm in diameter), the Acanthamoeba-infecting Pandoravirus salinus remained the most spectacular and intriguing virus since its description in 2013. Following its isolation from shallow marine sediment off the coast of central Chile, that of its relative Pandoravirus dulcis from a fresh water pond near Melbourne, Australia, suggested that they were the first representatives of an emerging worldwide-distributed family of giant viruses. This was further suggested when P. inopinatum discovered in Germany, was sequenced in 2015. We now report the isolation and genome sequencing of three new strains (P. quercus, P.neocaledonia, P. macleodensis) from France, New Caledonia, and Australia. Using a combination of transcriptomic, proteomic, and bioinformatic analyses, we found that these six viruses share enough distinctive features to justify their classification in a new family, the Pandoraviridae, distinct from that of other large DNA viruses.
