Role of Catecholate Siderophores in Gram-Negative Bacterial Colonization of the Mouse Gut
(PLos One, 2012-11-29)
We investigated the importance of the production of catecholate siderophores, and the utilization of their iron (III) complexes, to colonization of the mouse intestinal tract by Escherichia coli. First, a ΔtonB strain was ...
Elevated Levels of the Vesicular Monoamine Transporter and a Novel Repetitive Behavior in the Drosophila Model of Fragile X Syndrome
(PLos One, 2011-11-02)
Fragile X Syndrome (FXS) is characterized by mental impairment and autism in humans, and it often features hyperactivity and repetitive behaviors. The mechanisms for the disease, however, remain poorly understood. Here we ...
Studies in RF Power Communication, SAR, and Temperature Elevation in Wireless Implantable Neural Interfaces
(PLos One, 2013-11-06)
Implantable neural interfaces are designed to provide a high spatial and temporal precision control signal implementing high degree of freedom real-time prosthetic systems. The development of a Radio Frequency (RF) wireless ...
Functional Biogeography as Evidence of Gene Transfer in Hypersaline Microbial Communities
(PLos One, 2010-09-23)
BackgroundHorizontal gene transfer (HGT) plays a major role in speciation and evolution of bacteria and archaea by controlling gene distribution within an environment. However, information that links HGT to a natural ...
Microbial Community Analysis of a Coastal Salt Marsh Affected by the Deepwater Horizon Oil Spill
(PLos One, 2012-07-18)
Coastal salt marshes are highly sensitive wetland ecosystems that can sustain long-term impacts from anthropogenic events such as oil spills. In this study, we examined the microbial communities of a Gulf of Mexico coastal ...
Metapopulation Dynamics Enable Persistence of Influenza A, Including A/H5N1, in Poultry
(PLos One, 2013-12-02)
Highly pathogenic influenza A/H5N1 has persistently but sporadically caused human illness and death since 1997. Yet it is still unclear how this pathogen is able to persist globally. While wild birds seem to be a genetic ...
Ultrasound-Mediated DNA Transformation in Thermophilic Gram-Positive Anaerobes
(PLos One, 2010-09-04)
BackgroundThermophilic, Gram-positive, anaerobic bacteria (TGPAs) are generally recalcitrant to chemical and electrotransformation due to their special cell-wall structure and the low intrinsic permeability of plasma ...
Ecological Energetics of an Abundant Aerial Insectivore, the Purple Martin
(PLos One, 2013-09-25)
The atmospheric boundary layer and lower free atmosphere, or aerosphere, is increasingly important for human transportation, communication, environmental monitoring, and energy production. The impacts of anthropogenic ...
Simulated Impacts of Tropopause-Penetrating Convection on the Chemical Composition of the Upper Troposphere and Lower Stratosphere
(2019)
Tropopause-penetrating convection is capable of rapidly transporting air from the lower troposphere to the upper troposphere and lower stratosphere (UTLS). Since the vertical redistribution of gases in the atmosphere by ...
Nutritional Basis for Colonization Resistance by Human Commensal Escherichia coli Strains HS and Nissle 1917 against E. coli O157:H7 in the Mouse Intestine
(PLos One, 2013-01-17)
Escherichia coli is a single species consisting of many biotypes, some of which are commensal colonizers of mammals and others that cause disease. Humans are colonized on average with five commensal biotypes, and it is ...
