PAS Signaling Mechanisms in Aer and Aer2
… β-sheet flanked by several α- helices. The aerotaxis receptor Aer from Escherichia coli and the Aer2 chemoreceptor from Pseudomonas aeruginosa both contain PAS domains. Aer senses oxygen (O2) indirectly via an FAD cofactor bound to its PAS domain, while Aer2 directly binds O2 to its PAS …

HAMP Domain and Signaling Mechanism of the Aer Protein
<p><em>Escherichia coli</em> utilizes the Aer protein to sense changes in the intracellular energy level and guide the bacteria to a niche where the cellular energy level is optimal. Aer contains a PAS sensory domain and an FI fragment in the N terminus and a chemotaxis signaling domain in the C …

Oxygen Sensing by the Aer and Tsr Receptors of Escherichia Coli
… oxygen concentration of its environment via the Aer and Tsr receptors, and swims to an oxygen concentration that provides optimal energy generation. Aer and Tsr do not sense oxygen per se but, sense the internal energy state via the electron transport system (ETS) in a previously unidentified …

Identification and Characterization of Aer, an Energy Sensor in Escherichia Coli
… the mechanism of signal transduction by Aer, the aerotaxis transducer in <em>E.coli</em>. A computerized search of GenBank revealed an open reading frame at 69.1 min on the E.co//chromosome that had a C-terminal fragment with 96.7% identity to the highly conserved domain of Tsr. The open …

Structural Dynamics and Signaling Roles of the Aer PAS and F1 Regions
<p>The Aer aerotaxis receptor in <em>Escherichia coli</em> mounts such a rapid response to redox that <em>E. coli </em>changes its swimming behavior within 100 ms after an oxygen pulse. This receptor is a membrane-bound homodimer, and it monitors internal energy (redox) via an FAD cofactor bound to …

Anaerobic / Aerobic Digestion for Enhanced Solids and Nitrogen Removal
Anaerobic digestion of wastewater sludge has widely been in application for stabilization of sludge. With the increase in hauling cost and many environmental and health concerns regarding land application of biosolids, digestion processes generating minimized sludge with better effluent …

Genómica funcional y disección molecular de FOXD1 para la identificación de nuevos biomarcadores genéticos asociados a patologías de la reproducción de origen endometrial y placentario
El aborto espontáneo recurrente (AER) se define como dos o más pérdidas consecutivas de la gestación antes de la semana 20 del desarrollo intrauterino. Esta patología afecta a aproximadamente entre el 1% y el 5% de las parejas. La etiología del AER se puede dividir en causas no-genéticas como …

The kidney in diabetes mellitus : urinary transfer in excretion, hypertension, the Renin-Angiotensin-Aldosterone system, and the role of angiotensin converting enzyme inhibitors in therapy
… elevated urinary albumin excretion rates [AER] and hypertension. Preliminary data from several groups suggest that diabetic patients handle transferrin, a protein similar in size and weight, in a different fashion from albumin. In the first part of this thesis I report the results of …

Biological Treatment of a Synthetic Dye Water and an Industrial Textile Wastewater Containing Azo Dye Compounds
In this research, the ability of anaerobic and aerobic biological sludges to reduce and stabilize azo dye compounds was studied. Synthetic dye solutions and an industrial textile wastewater were both treated using anaerobic and aerobic biomass, separately and in sequential step-treatment processes. …

Estudio e implementación de algoritmos de fusión sensorial para sensores pulsantes y clásicos con protocolo AER de comunicación y aplicación en sistemas robóticos neuroinspirados
… and connected to a robotic platform using the AER bus show an excellent behaviour in terms of power and resources consumption. They show also an accurate and precise functioning for reaching and tracking movements when the target is supplied by an AER retina or jAER. Thus, a full neuro-inspired …

The auditory evoked response as an indicator of stress in free-ranging animals
… and the Auditory Evoked Response (AER), allows the monitoring of cardiac (heart) activity through the electrocardiogram (ECG), and provides support for measurement of additional stress parameters such as temperature, respiration rate, and physical activity. The long-range and …

The Effects of Mental Skills Training on Serve Accuracy of an Intercollegiate Volleyball Team
… were utilized: season ace-to-error ratio (AER) and good serve percentage (GSP; i.e., percent serves in home matches that pulled the opponent's setter off the net). These measures were highly correlated (r = .85, p < .01). Both were utilized, as GSP was more sensitive than the traditional …

An analysis of environmental regulatory compliance
… CBM and how well the Alberta Energy Regulator's (AER) regulatory framework protects the environment and ensures regulatory compliance compared to that of the government of New South Wales and make recommendations to the AER on how to enhance its regulatory practices.

Speech-Based Emotion Modelling and Mental Disorder Detection
… first explores automatic emotion recognition (AER) from speech input. Current AER systems face two primary challenges: (i) the mismatch between research experiments and practical applications such as the use of reference transcriptions and sentence segmentation; (ii) the inconsistency of …

Memory-related cognitive modulation of human auditory cortex: Magnetoencephalography-based validation of a computational model
… modulation of human auditory evoked responses (AER) induced by the overt processing of auditory STM during task performance. To accomplish this goal, a new signal processing method based on independent component analysis (ICA) was developed for removing artifact contamination in the MEG …

Cellular principles of Xenopus appendage regeneration
… centre cell type, apical-ectodermal-ridge (AER) cells. By using ex vivo regenerating limb cultures, I then demonstrated that, during tadpole development, there is an enrichment of mature chondrogenic lineage cells which express inhibitory secreted factors, including NOGGIN, blocking AER cell …

Dynamic patterning of maternal mRNAs in the Early C. elegans embryo
… rest of the genome. The Apical Epidermal Ridge (AER) in vertebrates is essential to the outgrowth of a growing limb bud. Induction and maintenance of the AER reply heavily on the coordination and signaling between two surrounding cell types: ectodermal and mesenchymal cells. In morphogenesis …

Performance evaluation of active network-based unicast and multicast congestion control protocols
… Error Recovery/Nominee Congestion Avoidance (AER/NCA), which uses active services to recover from loss at the point of loss and assists the congestion control. The use of AN helps the multicast application to achieve optimal data rates. We compare the results of AER/NCA TCP-friendliness to …
