Project description:Reduction in visceral adipose tissue (VAT) mass reduces body weight and metabolic disease risk in obese patients. However surgical removal of VAT is highly invasive and thus not clinically feasible. We developed an injectable ice slurry for selective reduction of adipose tissue through cryolipolysis. The aim of this study was to investigate safety, feasibility and mechanism of ice slurry-induced cryolipolysis of VAT. Perigonadal VAT in diet-induced obese mice and rats was subjected to slurry or sham treatment. Body weight and blood chemistry were monitored for 56 days post-treatment. Histological analysis and molecular studies were performed to elucidate mechanisms of fat reduction. Treatment of VAT was well tolerated in all animals. Slurry induced adipocyte cell death via selective cryolipolysis; significant weight loss was noted at day 21 post-treatment. RNA sequencing from treated VAT samples showed increased expression of genes involved in inflammation, immune response, collagen biosynthesis and wound healing, and decreased expression of adipokines. This study demonstrates that slurry treatment is safe and effective in inducing cryolipolysis of VAT and subsequent weight loss in rodents. Ice slurry is promising as a minimally-invasive treatment to reduce visceral adipose tissue.

YerA41, a Yersinia ruckeri bacteriophage: determination of non-sequencable bacteriophage genome and investigation of bacterial response to infection.

Project description:YerA41 is a myoviridae bacteriophage that was originally isolated due its ability to infect Yersinia ruckeri bacteria, the causative agent of enteric redmouth disease of salmonid fish. Several attempts to determine its genomic DNA sequence using traditional and next generation sequencing technologies failed, indicating that the phage genome is modified such way that it is an unsuitable template for PCR amplification and sequencing. To determine the YerA41 genome sequence we isolated RNA from phage-infected Y. ruckeri cells at different time points post-infection, and sequenced it. The host-genome specific reads were substracted and de novo assembly was performed on the unaligned reads.

Porin expression in clinical isolates of Klebsiella pneumoniae: a comparison of SDS-PAGE and MALDI-TOF/MS and limitations of whole genome sequencing analysis Porin expression in clinical isolates of Klebsiella pneumoniae: a comparison of SDS-PAGE and MALDI-TOF/MS and limitations of whole genome sequencing analysis

Project description:Precise definition of porin profiles is of critical importance to understand the role of porins in antimicrobial resistance. In this study, the outer membrane proteins (OMP) profiles of 26 clinical isolates of Klebsiella pneumoniae and of strain ATCC 13883 (wild-type) and ATCC 700603 (producing SHV-18) have been determined using both sodium-dodecyl-sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and matrix-assisted laser desorption/ionization–time of flight/mass spectrometry (MALDI-TOF/MS). SDS-PAGE was performed using both homemade and commercial gels, and protein bands were identified by liquid chromatography coupled to mass spectrometry. A rapid extraction method was used to analyse OMPs by MALDI-TOF/MS. The sequences of porin genes were obtained by whole genome sequencing (WGS) and mutations were defined by BLAST. Same results were obtained for all strains either using SDS-PAGE or MALDI-TOF/MS. SDS-PAGE showed protein bands of ~35, ~36, and ~37 KDa, identified as OmpA, OmpK36 and OmpK35, respectively. By MALDI-TOF/MS, peaks at ~35700 (OmpA), ~37000 (OmpK35), and ~38000 (OmpK36) m/z were detected. ompK35 was intact in nine wild-type isolates and was truncated in 13 isolates, but OmpK35 was not observed in 3 isolates without mutations in ompK35. One point mutation was detected in another isolate and multiple mutations were detected in the remaining isolate. ompK36 was truncated in two isolates lacking this protein and presented one point mutation (n=1) or multiple mutations in the remaining isolates. In conclusion, MALDI-TOF/MS was reliable for porin detection, but because of the complex regulation of porin genes, WGS cannot always anticipate protein expression, as observed with SDS-PAGE and MALDI-TOF/MS.
