    Thiamine Concentrations in Extruded Dog and Cat Food & Determination of Thiamine Status in Healthy Dogs and Cats and Comparison with Hospitalized Inappetent Animals by Georgia Kritikos A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Clinical Studies Guelph, Ontario, Canada © Georgia Kritikos, August, 2017 ABSTRACT THIAMINE CONCENTRATIONS IN EXTRUDED DOG AND CAT FOOD & DETERMINATION OF THIAMINE STATUS IN HEALTHY DOGS AND CATS AND COMPARISON WITH HOSPITALIZED INAPPETENT ANIMALS Georgia Kritikos Advisor: University of Guelph, 2017 Dr. Adronie Verbrugghe Thiamine is a water-soluble vitamin and a dietary requirement for dogs and cats. It has a critical role in energy metabolism. As pet owners may freeze excess pet food in an attempt to maintain freshness, this thesis investigates the effect of freezing on thiamine in extruded dog and cat foods. Storage temperature did not affect thiamine concentrations of extruded diets, but thiamine significantly increased over time. Additionally, this thesis examines thiamine status of healthy dogs and cats in comparison to inappetent patients presenting to a tertiary referral hospital, and determines the effect of supplementation on resultant thiamine status in inappetent dogs. We found that thiamine diphosphate (TDP) and unphosphorylated thiamine status of healthy dogs declined with age. This relationship was not present in cats. TDP status was higher in inappetent dogs compared to healthy dogs. Supplementation led to higher TDP status in inappetent dogs compared to baseline TDP status. ACKNOWLEDGEMENTS First, I’d like to thank my advisor, Dr. Adronie Verbrugghe. I came into my degree with a love for nutrition and an idea that I wanted to pursue nutrition as a career.

Lewis1 Recent studies suggest that gut microbiomes of urban-industrialized societies are different from those of traditional peoples. Here we examine the relationship between lifeways and gut microbiota through taxonomic and functional potential characterization of faecal samples from hunter-gatherer and traditional agriculturalist communities in Peru and an urban-industrialized community from the US. We find that in addition to taxonomic and metabolic differences between urban and traditional lifestyles, hunter-gatherers form a distinct sub-group among traditional peoples. As observed in previous studies, we find that Treponema are characteristic of traditional gut microbiomes. Moreover, through genome reconstruction (2.2–2.5 MB, coverage depth  26–513) and functional potential character- ization, we discover these Treponema are diverse, fall outside of pathogenic clades and are similar to Treponema succinifaciens, a known carbohydrate metabolizer in swine.

Abstract The general paradigm that emerges from the analysis of the transcriptome of the malaria parasite Plasmodium falciparum is that the expression clusters of genes that code for enzymes engaged in the same cellular function is coordinated. Here the consistency of this perception is examined by analysing specific pathways that metabolically-linked. The pentose phosphate pathway (PPP) is a fundamental element of cell biochemistry since it is the major pathway for the recycling of NADP+ to NADPH and for the production of ribose-5-phosphate that is needed for the synthesis of nucleotides. The function of PPP depends on the synthesis of NADP+ and thiamine pyrophosphate, a co-enzyme of the PPP enzyme transketolase.

Verbatim copying and redistribution of this article are permitted in any medium for any purpose, provided this notice is preserved along with the article's original URL. Abstract Background: Thiamine diphosphate (ThDP) is the active form of thiamine, and it serves as a cofactor for several enzymes, both cytosolic and mitochondrial. Isolated mitochondria have been shown to take up thiamine yet thiamine diphosphokinase is cytosolic and not present in mitochondria. Previous reports indicate that ThDP can also be taken up by rat mitochondria, but the kinetic constants associated with such uptake seemed not to be physiologically relevant. Results: Here we examine ThDP uptake by mitochondria from several human cell types, including cells from patients with thiamine-responsive megaloblastic anemia (TRMA) that lack a functional thiamine transporter of the plasma membrane. Although mitochondria from normal lymphoblasts took up thiamine in the low micromolar range, surprisingly mitochondria from TRMA lymphoblasts lacked this uptake component. ThDP was taken up efficiently by mitochondria isolated from either normal or TRMA lymphoblasts.

  • Novel Plasmodium Falciparum Metabolic Network Reconstruction Identifies Shifts Associated with Clinical Antimalarial Resistance Maureen A
    Carey et al. BMC Genomics (2017) 18:543 DOI 10.1186/s12864-017-3905-1 RESEARCHARTICLE Open Access Novel Plasmodium falciparum metabolic network reconstruction identifies shifts associated with clinical antimalarial resistance Maureen A. Carey1, Jason A. Papin2* and Jennifer L. Guler3,4* Abstract Background: Malaria remains a major public health burden and resistance has emerged to every antimalarial on the market, including the frontline drug, artemisinin. Our limited understanding of Plasmodium biology hinders the elucidation of resistance mechanisms. In this regard, systems biology approaches can facilitate the integration of existing experimental knowledge and further understanding of these mechanisms. Results: Here, we developed a novel genome-scale metabolic network reconstruction, iPfal17, of the asexual blood-stage P. falciparum parasite to expand our understanding of metabolic changes that support resistance. We identified 11 metabolic tasks to evaluate iPfal17 performance. Flux balance analysis and simulation of gene knockouts and enzyme inhibition predict candidate drug targets unique to resistant parasites. Moreover, integration of clinical parasite transcriptomes into the iPfal17 reconstruction reveals patterns associated with antimalarial resistance. These results predict that artemisinin sensitive and resistant parasites differentially utilize scavenging and biosynthetic pathways for multiple essential metabolites, including folate and polyamines. Our findings are consistent with experimental literature, while generating

I ABSTRACT ABSTRACT Inflammatory bowel diseases (IBD) are associated with compositional and functional changes of the intestinal microbiota, but specific contributions of individual bacteria to chronic intestinal inflammation remain unclear. Enterococcus faecalis is a resident member of the human intestinal core microbiota that has been linked to the pathogenesis of IBD and induces chronic colitis in susceptible monoassociated IL10-deficient (IL-10-/-) mice. In this study, we characterized the colitogenic activity of E. faecalis as part of a simplified microbial consortium based on human strains (SIHUMI). RNA sequencing analysis of E. faecalis isolated from monoassociated wild type and IL-10-/- mice identified 408 genes including 14 genes of the ethanolamine utilization (eut) locus to be significantly upregulated in response to inflammation. Despite considerable upregulation of eut genes, deletion of ethanolamine utilization (∆eutVW) had no impact on E. faecalis colitogenic activity in monoassociated IL-10-/- mice. However, replacement of the E. faecalis wild type bacteria by a ∆eutVW mutant in SIHUMI-colonized IL-10-/- mice resulted in exacerbated colitis, suggesting protective functions of E.
