Project description:D-galactose orally intake ameliorate DNCB-induced atopic dermatitis by modulating microbiota composition and quorum sensing. The increased abundance of bacteroidetes and decreased abundance of firmicutes was confirmed. By D-galactose treatment, Bacteroides population was increased and prevotella, ruminococcus was decreased which is related to atopic dermatitis.
Project description:The main goal of the project is the study the associations between the gut metagenome and human health. The dataset contains data for n=7211 FINRISK 2002 participants who underwent fecal sampling. Demultiplexed shallow shotgun metagenomic sequences were quality filtered and adapter trimmed using Atropos (Didion et al., 2017), and human filtered using Bowtie2 (Langmead and Salzberg, 2012).

Project description:Interventions: Patients without the Penrose drain
Patients with the Penrose drain: After suturing fascia, implant 6mm-PD with a slit to cover the whole length of wound. Change the gauze to cover the top of the drain every day until drain is removed. The 6-mm Penrose drain produced by Kaneka corporation should be used.
Primary outcome(s): The rate of superficial surgical site infection in abdominal medial incision.
Study Design: Parallel Randomized
Project description:Background: The soil environment is responsible for sustaining most terrestrial plant life on earth, yet we know surprisingly little about the important functions carried out by diverse microbial communities in soil. Soil microbes that inhabit the channels of decaying root systems, the detritusphere, are likely to be essential for plant growth and health, as these channels are the preferred locations of new root growth. Understanding the microbial metagenome of the detritusphere and how it responds to agricultural management such as crop rotations and soil tillage will be vital for improving global food production. Methods: The rhizosphere soils of wheat and chickpea growing under + and - decaying root were collected for metagenomics sequencing. A gene catalogue was established by de novo assembling metagenomic sequencing. Genes abundance was compared between bulk soil and rhizosphere soils under different treatments. Conclusions: The study describes the diversity and functional capacity of a high-quality soil microbial metagenome. The results demonstrate the contribution of the microbiome from decaying root in determining the metagenome of developing root systems, which is fundamental to plant growth, since roots preferentially inhabit previous root channels. Modifications in root microbial function through soil management, can ultimately govern plant health, productivity and food security.
Project description:Interventions: Measure amylase levels in drain fluid daily after low colorectal anastomoses as an early indicator of anastomotic leak.
- a small sample of drain fluid will be collected daily while pelvic drain is in situ during hospital admission following colorectal surgery and samples will be sent to the local pathology service for measurement of amylase
- the amylase levels in drain fluid at each collection while the drain is in-situ will be collected and correlated to the clinical course
- clinical course following surgery will be observed during admission (and data collected after patient has been discharged, retrospective data collection).
- Follow up consultation at 6 weeks following surgery
Primary outcome(s): Daily amylase levels in the drain fluid post-operatively. The measurement of amylase in drain fluid is measured and reported by local pathology service.[Day 1, Day 2, Day 3, Day 4 and Day 5, post operatively, or until pelvic drain is removed. ]
