Project description:We carried out a prospective, longitudinal, single-center, observational cohort study of patients with confirmed acute methanol poisoning that were treated in hospitals during a mass methanol poisoning outbreak in the Czech Republic in 2012. Venous blood for proteomic analysis was obtained from 24 patients with confirmed acute methanol poisoning upon admission to the hospital (group M (“Methanol”)) with heparin administration for hemodialysis and ethanol or fomepizole administration as the antidote to block ADH. In the follow-up group of survivors of methanol poisoning (group S (“Survivors”)), venous blood samples for proteomic analysis were obtained from 46 patients during the examination, which took place 4 years after discharge from the hospital. For the control group not exposed to methanol, 24 healthy subjects were recruited (group C, “Controls”). Blood samples were spun, the serum was separated, and the samples were frozen to −80 °C until the analyses. Blood serum samples were depleted of most abundant serum proteins using Agilent MARS 14 column, samples fractionated and fractions containing proteins of interest precipitated. Samples were analyzed using LC-MS/MS Thermo Orbitrap Fusion (UHPLC-ESI-Q-OT-qIT) and identified proteins with differential expression.
Project description:This study will measure Prostate Specific Antigen (PSA) values in men with Inflammatory Bowel Disease (IBD) before, during, and following a flare. In addition, the effect of any PSA increase will be analyzed and correlated to the location of disease (rectal vs. other). Study findings may help men with IBD by identifying pitfalls in prostate cancer screening for this population and help to stratify and understand the effect IBD has on the prostatic milieu. By optimizing how men with IBD are screened for prostate cancer, future unnecessary healthcare encounters and expenditures may be reduced for this patient group.
Project description:We recently showed that methanol emitted by wounded plants might function as a signaling molecule for plant-to-plant and plant-to-animal communications. In mammals, methanol is considered a poison because the enzyme alcohol dehydrogenase (ADH) converts methanol into toxic formaldehyde. However, the detection of methanol in the blood and exhaled air of healthy volunteers suggests that methanol may be a chemical with specific functions rather than a metabolic waste product. Using a genome-wide analysis of the mouse brain, we demonstrated that an increase in blood methanol concentration led to a change in the accumulation of mRNAs from genes primarily involved in detoxification processes and regulation of the alcohol/aldehyde dehydrogenases gene cluster. Removal of the intestine significantly decreased the rate of methanol addition to the plasma and suggested that the gut flora may be involved in the endogenous production of methanol. Liver mRNA quantification showed changes in the accumulation of mRNAs from genes involved in cell signalling and detoxification processes. We hypothesized that endogenous methanol acts as a regulator of homeostasis by controlling the mRNA synthesis
Project description:Clinical remission is apparent when laboratory markers of inflammation are normal and clinical symptoms are absent. However, sub-clinical inflammation can still be present. A detailed analysis of the immune status during this inactive state of disease may provide a useful tool to subcategorize patients with subclinical immune activation We performed (un)supervised clustering analysis of IBD-associated genes and applied IngenuityM-BM-. pathway software to identify specific molecular profiles between patients. We analyzed RNA gene expression profiles of peripheral blood leucocytes (PBL) from pediatric IBD patients in clinical remission and age-matched controls.
Project description:Group 3 innate lymphoid cells (ILC3s) are abundant in the developing or healthy intestine to critically support tissue homeostasis in response to microbial cues and other environmental signals. However, during gastrointestinal disease including infections, colorectal cancer, or inflammatory bowel disease (IBD), intestinal ILC3 numbers are dramatically reduced and the remaining ILC3s become dysfunctional which fuels disease and barrier breakdown. To define the underlying transcriptomic changes, we employed RNA sequencing of ILC3s from IBD patients. This may help to gain a deeper understanding of the mechanisms driving these alterations and ultimately lead to novel preventive, diagnostic, or therapeutic opportunities in IBD.
