Lysine Biosynthesis In Bacteria: A Metallodesuccinylase As A Potential Antimicrobial Target, 2018 Silesian University of Technology
Lysine Biosynthesis In Bacteria: A Metallodesuccinylase As A Potential Antimicrobial Target, Danuta M. Gillner, Daniel P. Becker Ph.D., Richard C. Holz
Richard C. Holz
In this review, we summarize the recent literature on dapE-encoded N-succinyl-l,l-diaminopimelic acid desuccinylase (DapE) enzymes, with an emphasis on structure–function studies that provide insight into the catalytic mechanism. Crystallographic data have also provided insight into residues that might be involved in substrate and hence inhibitor recognition and binding. These data have led to the design and synthesis of several new DapE inhibitors, which are described along with what is known about how inhibitors interact with the active site of DapE enzymes, including the efficacy of a moderately strong DapE inhibitor.
Sodium Polyphosphate And Polyethylenimine Enhance The Antimicrobial Activities Of Plant Essential Oils, 2018 Iowa State University
Sodium Polyphosphate And Polyethylenimine Enhance The Antimicrobial Activities Of Plant Essential Oils, Heidi A. Wright, Byron F. Brehm-Stecher
Byron F. Brehm-Stecher
Plant extracts have been used for millennia for treatment of disease, with much recent interest focusing on the antimicrobial activities of plant essential oils (EOs). Although EOs are active against common microbial pathogens, their effective use as topical, environmental, or food antimicrobials will require EO-based formulations with enhanced antimicrobial activities. In this study, two polyionic compounds, sodium polyphosphate (polyP, a polyanion) and polyethylenimine (PEI, a polycation), were evaluated for their abilities to enhance the antimicrobial activities of six EOs against the human pathogens Escherichia coli O157:H7, Salmonella enterica subsp. enterica ser. Minnesota, Pseudomonas aeruginosa, Listeria monocytogenes, Staphylococcus aureus, and ...

Is There A Link Between Aging And Microbiome Diversity In Exceptional Mammalian Longevity?, 2018 University College Dublin - Ireland
Is There A Link Between Aging And Microbiome Diversity In Exceptional Mammalian Longevity?, Graham M. Hughes, John Leech, Sebastien J. Puechmaille, Jose V. Lopez, Emma C. Teeling
Biology Faculty Articles
A changing microbiome has been linked to biological aging in mice and humans, suggesting a possible role of gut flora in pathogenic aging phenotypes. Many bat species have exceptional longevity given their body size and some can live up to ten times longer than expected with little signs of aging. This study explores the anal microbiome of the exceptionally long-lived Myotis myotis bat, investigating bacterial composition in both adult and juvenile bats to determine if the microbiome changes with age in a wild, long-lived non-model organism, using non-lethal sampling. The anal microbiome was sequenced using metabarcoding in more than 50 ...
Stress-Induced Reorganization Of The Mycobacterial Membrane Domain, 2018 University of Massachusetts Amherst
Stress-Induced Reorganization Of The Mycobacterial Membrane Domain, Jennifer M. Hayashi, Kirill Richardson, Emily S. Melzer, Steven J. Sandler, Bree B. Aldridge, M. Sloan Siegrist, Yasu S. Morita
Microbiology Department Faculty Publication Series
Cell elongation occurs primarily at the mycobacterial cell poles, but the molecular mechanisms governing this spatial regulation remain elusive. We recently reported the presence of an intracellular membrane domain (IMD) that was spatially segregated from the conventional plasma membrane in Mycobacterium smegmatis. The IMD is enriched in the polar region of actively elongating cells and houses many essential enzymes involved in envelope biosynthesis, suggesting its role in spatially restricted elongation at the cell poles. Here, we examined reorganization of the IMD when the cells are no longer elongating. To monitor the IMD, we used a previously established reporter strain expressing ...

Prospective Comparison Of Point-Of-Care Device And Standard Analyzer For Monitoring Of International Normalized Ratio In Outpatient Oral Anticoagulant Clinic, Bushra Moiz, Ahmed Raheem, Anila Rashid, Muhammad Hasan, Lena Jafri
Department of Pathology and Laboratory Medicine
Point-of-care testing (POCT) coagulometers are increasingly being used in the hospital setting and patients’ self-testing. We determined the agreement of prothrombin time international normalized ratio (INR) results by POCT coagulometer and laboratory instrument through a comparative analysis and investigated whether the results of POCT coagulometer can reliably be used without being confirmed by standard laboratory analyzer. A total of 200 INR measurements by POCT coagulometer (CoaguChek XS Pro) and laboratory analyzer (Sysmex CS2000i) were compared using Passing-Bablok regression analysis and Bland-Altman plot. Agreement of the INR measurement was further analyzed in relation to dosing decision. The correlation of INR measurements ...
A Link Between Gut Microbes & Depression: Microbial Activation Of The Human Kynurenine Pathway, 2018 Claremont McKenna College
A Link Between Gut Microbes & Depression: Microbial Activation Of The Human Kynurenine Pathway, Christina Cobb
CMC Senior Theses
Our gut microbiota is involved in human development, nutrition, and the pathogenesis of gut disorders, but has more recently been implicated as a possible mechanism in the pathophysiology of several brain disorders, including disorders of mood and affect, such as depression. Researchers have referred to this dynamic, bidirectional signaling pathway between the gut and the brain as the “gut-brain axis.” However, most research on this axis has been limited to rodent studies, and there has been little insight into the mechanism behind it. I propose that the kynurenine pathway, where tryptophan is converted to kynurenine, is a compelling mechanism mediating ...

We predict these genes encode components of a branched-chain amino acid ATP Binding Cassette (ABC) transporter: 1) Mrub_2120 (DNA coordinates 2169247-2170416 on the reverse strand) encodes the branched-chain amino acid binding protein that is localized to the periplasm; 2) Mrub_2121 (DNA coordinates 2170433..2171353 on the reverse strand) encodes the first TMD; 3) Mrub_2122 (DNA coordinates 2171365..2172279 on the reverse strand) encodes the second TMD; 4) Mrub_2123 (DNA coordinates 2172276..2173028 on the reverse strand) encodes the first ...
Pulmonary Alveolar Proteinosis- A Case Report, 2017 Orlando Regional Medical Center
Pulmonary Alveolar Proteinosis- A Case Report, Renee M. Horner, Douglas S. Gardenhire, Ralph D. Zimmerman
Internet Journal of Allied Health Sciences and Practice
Background: Pulmonary Alveolar Proteinosis (PAP) is a rare pulmonary disorder caused by a congregation of excessive lipoproteinaceous material in the alveolar spaces due to impaired surfactant metabolism. The congregation of the protein in the alveolar space leads to difficulty in breathing, impaired pulmonary immunity, and susceptibility to both opportunistic and acquired pulmonary infections. Although Pulmonary Alveolar Proteinosis is rare, there are potential treatments. Whole-lung lavage is the most widely accepted therapy and course of treatment. An additional form of therapy, GM-CSF stimulating therapy, uses recombinant deoxyribonucleic acid (DNA) technology to increase white cell production.
Purpose: The purpose of this ...
Nutritional Regulation Of Sulfonamide Antibiotic Biodegradation By Microbacterium Sp. Strain C448, 2017 The University of Western Ontario
Nutritional Regulation Of Sulfonamide Antibiotic Biodegradation By Microbacterium Sp. Strain C448, Tonya Malcolm
Electronic Thesis and Dissertation Repository
Sulfonamide antibiotics are frequently released into the environment due to their widespread use in livestock production, imposing a potential selection pressure for the development and dissemination of sulfonamide resistance. Recently, a sulfonamide-degrading bacterium Microbacterium sp. Strain C448 was discovered, whose activity has the potential to be used as a sulfonamide removal strategy from agricultural soils. This research gains insight into the sulfonamide biodegradation pathway by 1) evaluating the nutritional regulation of sulfamethazine biodegradation and 2) undertaking a comparative proteomic analysis of cells grown in the presence and in the absence of sulfamethazine. The nutritional analyses revealed that increasing amounts of ...

Otitis media (OM) is a broad term describing a group of infectious and inflammatory disorders of the middle ear. Despite antibiotic therapy, acute OM can progress to chronic suppurative otitis media (CSOM) characterized by ear drum perforation and purulent discharge. Pseudomonas aeruginosa is the most common pathogen associated with CSOM. Although, macrophages play an important role in innate immune responses but their role in the pathogenesis of P. aeruginosa-induced CSOM is not known. The objective of this study is to examine the interaction of P. aeruginosa with primary macrophages. We observed that P. aeruginosa enters and multiplies inside human and ...
Quantatative Analysis Of Microbial Abundance Within Arctic Fjord Sediments Assessed Through Direct Counting, 2017 University of Tennessee, Knoxville
Quantatative Analysis Of Microbial Abundance Within Arctic Fjord Sediments Assessed Through Direct Counting, Alex Taylor Swystun
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Microbes found in the marine sediments are responsible for the production of nearly half of the carbon dioxide found in the atmosphere (Arrigo, 2005). The fjords of Svalbard (79°N) are not considered typical marine sediments because high iron content influences unique subsurface redox chemistry. Radiotracer studies have shown that these sediments contain active bacterial sulfate-reducing communities (Finke et al., 2016). In addition to bacteria, archaeal cells within these sediments have been in aggregates encompassed by sulfate-reducing bacteria (Ravenschlag et al., 2001). These anaerobic organisms participate in mediating environmental biogeochemical cycles, including the oxidation of methane (Ravenschlag et al., 2001 ...
Evidence For The Priming Effect In Single Strain And Simplified Communities Of Estuarine Bacteria, 2017 University of Tennessee, Knoxville
Evidence For The Priming Effect In Single Strain And Simplified Communities Of Estuarine Bacteria, Abigail Amina Edwards
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Through their transformation of naturally occurring organic matter, coastal marine bacteria play an essential role in carbon cycling. A phenomenon termed the priming effect (PE) occurs when microbial communities remineralize recalcitrant organic matter faster in the presence of labile organic matter and may be prevalent in coastal systems. To understand how microbial community members interact to induce PE, it is essential to first understand the mechanisms underlying PE in single strains and simplified bacterial communities. The effect to which different concentrations and sources of labile carbon stimulated the production of bacterial biomass from riverine organic matter by two marine bacteria ...

Honors Projects and Posters
Colorectal cancer kills over 50,000 people per year in the United States. While individual drugs can be somewhat effective, the median survival remains only 25-28 months. New therapies are needed, and dual targeted inhibitors are a promising area. A total of 7 cell lines, 4 of which are presented, were treated in varying concentrations of TAK228, an mTORC1/2 inhibitor, and trametinib, a MEK1/2 inhibitor Proliferation, apoptosis, and viability assays as well as immunoblotting were performed to determine the mechanism and efficacy. Immunoblotting determined that the target of TAK228 is mTORC1/2 and that Survivin may be a ...
Mechanical Test Methods For Assessing Porcine Carotid And Uterine Artery Burst Pressure Following Ex Vivo Ultrasonic Ligature Seal And Transection, Carissa M. Krane, Margaret Pinnell, Courtney Gardner, Mercedes Thompson, James Coleman, Robert Wilkens
Robert J. Wilkens
A test method was developed to identify those variables important for assessing the performance of ultrasonic surgical devices in ex vivo ligature sealing of porcine carotid and uterine arteries. Ruggedness testing using a small sample size in pilot experiments was conducted using a newly developed test method in an effort to assess the usefulness of this methodology and to identify test variables that might warrant further testing. The development of this test method included the use of a custom-designed prototypic tension device for load-controlled ex vivo vessel stretching during saline perfusion and subsequent seal and transection of porcine arteries with ...

UMass Center for Clinical and Translational Science Supported Publications
Fifty years after the discovery of Epstein-Barr virus (EBV), it remains unclear how primary infection with this virus leads to massive CD8 T-cell expansion and acute infectious mononucleosis (AIM) in young adults. AIM can vary greatly in severity, from a mild transient influenza-like illness to a prolonged severe syndrome. We questioned whether expansion of a unique HLA-A2.01-restricted, cross-reactive CD8 T-cell response between influenza virus A-M158 (IAV-M1) and EBV BMLF1280 (EBV-BM) could modulate the immune response to EBV and play a role in determining the severity of AIM in 32 college students. Only ex vivo total IAV-M1 and IAV-M1+EBV-BM ...
Effects Of Adenovirus Infection On The Localization Of Cellular Protein Pat1b, 2017 Georgia College and State University
Effects Of Adenovirus Infection On The Localization Of Cellular Protein Pat1b, Emilee Friedman, Kasey A. Karen
Georgia Journal of Science
Adenoviruses are a diverse family of nonenveloped, double-stranded DNA viruses with a variety of vertebrate hosts including humans. Over 50 serotypes of human adenovirus have been identified, and cause a number of illnesses, including conjunctivitis, gastroenteritis, and respiratory infections. The life cycle of adenovirus is divided into immediate early, early, and late phases, with immediate early proteins controlling transcription and the cell cycle, early proteins being largely regulatory, and late proteins being structural. Early proteins such as E4 11k have been demonstrated to relocalize key cellular proteins, including proteins found within mRNA processing bodies (p-bodies). It is hypothesized that E4 ...
