Summary Recent research has disclosed a tight connection between obesity, metabolic gut microbial activities and host health. Obtaining complete understanding of this relationship remains major goal. Here, we conducted comparative metagenomic metaproteomic investigation communities in faecal samples taken from an obese lean adolescent. By analysing the diversity 16S rDNA amplicons (10% operational phylogenetic units being common), 22 Mbp consensus metagenome sequences (∼ 70% common)...

Obesity is associated with multiple adverse health effects and a high risk of developing metabolic cardiovascular diseases. Therefore, there great need to identify circulating parameters that link changes in body fat mass obesity. This study combines proteomic metabolomic approaches molecules discriminate healthy lean from obese individuals an exploratory design. To correct for variations physical activity, participants performed one hour exercise bout exhaustion. Subsequently, factors...

Accumulation of fat mass in obesity may result from hypertrophy and/or hyperplasia and is frequently associated with adipose tissue (AT) dysfunction adults. Here we assessed early alterations AT biology function by comprehensive experimental clinical characterization 171 samples lean obese children aged 0 to 18 years. We show an increase adipocyte size number compared beginning childhood. These composition were accompanied decreased basal lipolytic activity significantly enhanced stromal...

Use of PET/MR in children has not previously been reported, to the best our knowledge. Children with systemic malignancies may benefit from reduced radiation exposure offered by PET/MR. We report initial experience hybrid imaging and current established sequence protocol after 21 studies 15 multifocal malignant diseases. The effective dose a scan was only about 20% that equivalent PET/CT examination. Simultaneous acquisition PET MR data combines advantages two separate modalities....

Due to their fundamentally different biology, archaea are consistently overlooked in conventional microbiome surveys. Using amplicon sequencing, we evaluated methodological set-ups detect samples from five body sites: respiratory tract (nasal cavity), digestive (mouth, appendix, and stool) skin. With optimized protocols, the detection of archaeal ribosomal sequence variants (RSVs) was increased one (found currently used, so-called "universal" approach) 81 RSVs a representative sample set....

Fusions involving NTRK1, NTRK2, and NTRK3 are oncogenic drivers occurring in a spectrum of mesenchymal neoplasms ranging from benign to highly malignant tumors. To gain further insights into the staining profile with pan-TRK assay, we analyzed large number soft tissue sarcomas correlated our findings molecular testing. Additionally, expand NTRK-fusion tumors by reporting lesion lung as well skin fibrous histiocytoma NTRK-fusion. We retrospectively reviewed diagnosed at Diagnostic Research...

Recent advances in the vitro characterization of human adult enteric neural progenitor cells have opened new possibilities for cell-based therapies gastrointestinal motility disorders. However, whether these are able to integrate within an vivo gut environment is still unclear. In this study, we transplanted progenitor-containing neurosphere-like bodies (NLBs) a mouse model hypoganglionosis and analyzed cellular integration NLB-derived cell types functional improvement. NLBs were propagated...

Mounting evidence suggests that acute appendicitis (AA) is not one but two diseases: complicated appendicitis, which associated with necrosis leading to perforation or periappendicular abscess, and uncomplicated does necessarily result in perforation. Even though AA the most frequent cause of surgery from abdominal pain, little known about origins etiopathogenesis this disease, much less regarding different disease types. In study, we investigated microbiome (inter-domain amplicon metagenome...
