Contribution of wild foods to diet, food security, and cultural values amidst climate change
(2019-11)Wild foods are recognized to contribute to diet and food security through enhancing the availability of local, diverse, and nonmarket food sources. We investigated the contribution of wild foods to diet, food security, and ... -
Antimicrobial activity of naturally occurring phenols and derivatives against biofilm and planktonic bacteria
(2019-10)Biofilm-forming bacteria present formidable challenges across diverse settings, and there is a need for new antimicrobial agents that are both environmentally acceptable and relatively potent against microorganisms in the ... -
Nisin penetration and efficacy against Staphylococcus aureus biofilms under continuous-flow conditions
(2019-07)Biofilms may enhance the tolerance of bacterial pathogens to disinfectants, biocides and other stressors by restricting the penetration of antimicrobials into the matrix-enclosed cell aggregates, which contributes to the ... -
Janthinobacterium CG23_2: comparative genome analysis reveals enhanced environmental sensing and transcriptional regulation for adaptation to life in an Antarctic supraglacial stream
(2019-10)As many bacteria detected in Antarctic environments are neither true psychrophiles nor endemic species, their proliferation in spite of environmental extremes gives rise to genome adaptations. Janthinobacterium sp. CG23_2 ... -
DropSOAC: Stabilizing Microfluidic Drops for Time-Lapse Quantification of Single-Cell Bacterial Physiology
(2019-09)The physiological heterogeneity of cells within a microbial population imparts resilience to stresses such as antimicrobial treatments and nutrient limitation. This resilience is partially due to a subpopulation of cells ... -
Long-Term Flow through Human Intestinal Organoids with the Gut Organoid Flow Chip (GOFlowChip)
(2019-09)Human intestinal organoids (HIOs) are millimeter-scale models of the human intestinal epithelium and hold tremendous potential for advancing fundamental and applied biomedical research. HIOs resemble the native gut in that ... -
Nursing Preference for Alcohol-Based Hand Rub Volume
(Cambridge University Press (CUP), 2019-09)Background:The effectiveness of alcohol-based hand rub (ABHR) is correlated with drying time, which depends on the volume applied. Evidence suggests that there is considerable variation in the amount of ABHR used by ... -
Facultative and anaerobic consortia of haloalkaliphilic ureolytic micro-organisms capable of precipitating calcium carbonate
(Wiley, 2019-08)Aims Development of biomineralization technologies has largely focused on microbially induced carbonate precipitation (MICP) via Sporosarcina pasteurii ureolysis; however, as an obligate aerobe, the general utility of ... -
Struvite Stone Formation by Ureolytic Biofilms
(2019)This chapter describes the role ureolytic biofilms (communities of microbes attached to surfaces) play in struvite stone formation in the urinary tract. The formation of struvite stones (MgNH4PO4·6H2O), commonly known as ... -
Measuring Antimicrobial Efficacy against Biofilms: A MetaAnalysis
(2019-05)Through a statistical meta-analysis of published data on antimicrobial efficacy against biofilms formed by two common bacterial species, it was concluded that the particular experimental method used is the most important ... -
Holistic Management of Textile Odor Using Novel Silver-Polymeric Complexes
(2018-08)Odor poses a growing concern in clothing and apparel applications due to laundering limitations at managing odor-causing microorganisms. Herein, a novel silver-polymer complex was applied to textile materials and studied ... -
Characterization and quantification of structure and flow in multichannel polymer membranes by MRI
(2019-01)Polymeric multichannel hollow fiber membranes were developed to reduce fiber breakage and to increase the volume-to-membrane-surface ratio and consequently the efficiency of filtration processes. These membranes are commonly ... -
Impact of an automated hand hygiene monitoring system and additional promotional activities on hand hygiene performance rates and healthcare-associated infections
(2019-07)Objective: Determine the impact of an automated hand hygiene monitoring system (AHHMS) plus complementary strategies on hand hygiene performance rates and healthcare-associated infections (HAIs). Design: Retrospective, ... -
A Novel Gastric Spheroid Co-culture Model Reveals Chemokine-Dependent Recruitment of Human Dendritic Cells to the Gastric Epithelium
(2019-03)Background & Aims Gastric dendritic cells (DCs) control the adaptive response to infection with Helicobacter pylori, a major risk factor for peptic ulcer disease and gastric cancer. We hypothesize that DC interactions ... -
Randomized controlled trial evaluating the antimicrobial efficacy of chlorhexidine gluconate and para-chloro-meta-xylenol handwash formulations in real-world doses
(2019-06)Chlorhexidine gluconate-based soaps have become the gold standard for handwashing in critical care settings and para-chloro-meta-xylenol is an effective alternative antibacterial active ingredient. This study benchmarked ... -
Who goes in and out of patient rooms? An observational study of room entries and exits in the acute care setting
(2019-05)The objective of this study is to determine what percentage of patient room entries and exits (opportunities) are attributed to health care personnel (HCP) and non-HCP. A total of 14,876 opportunities were observed by ... -
Kinetics of Calcite Precipitation by Ureolytic Bacteria under Aerobic and Anaerobic Conditions
(2019-05)The kinetics of urea hydrolysis (ureolysis) and induced calcium carbonate (CaCO3) precipitation for engineering use in the subsurface was investigated under aerobic conditions using Sporosarcina pasteurii (ATCC strain ... -
Quorum sensing inhibition as a promising method to control biofilm growth in metalworking fluids
(2019-04)Microbial contamination in metalworking systems is a critical problem. This study determined the microbial communities in metalworking fluids (MWFs) from two machining shops and investigated the effect of quorum sensing ... -
Dynamic processing of DOM: Insight from exometabolomics, fluorescence spectroscopy, and mass spectrometry
(2018-06)Dissolved organic matter (DOM) in freshwater environments is an important source of organic carbon, supporting bacterial respiration. Frozen environments cover vast expanses of our planet, with glaciers and ice-sheets ... -
Bacterial Adhesion and Biofilm Formation on Textured Breast Implant Shell Materials
(2019-04)"Background Bacterial biofilms have been implicated with breast implant complications including capsular contracture and anaplastic large-cell lymphoma. The actual mechanisms for either are still under active investigation ...
