MarR Family Transcriptional Regulators from Streptomyces coelicolor
… is the multiple antibiotic resistance regulator (MarR) family. These transcriptional regulators participate in many cellular processes and can provide valuable knowledge about transcriptional regulation in response to specific conditions. The closely related MarR homologs TamR (trans-aconitate …

Biophysical analysis of MarR family transcription factors from Streptomyces coelicolor
… it difficult to do this in a rational way. The MarR family of regulatory proteins (MFRs) represents an important group of transcriptional regulators. Named after the first to be characterized in Escherichia coli, the multiple antibiotic resistance repressor (MarR), the members of this family are …

Effects of Work Exposure on Maximum Acceptable Repetition Rates in a Manual Torquing Task
… resulting Maximum Acceptable Repetition Rates (MARR). However, it is unknown whether and how longer work exposure durations might influence MARRs. The current study investigated the effects of work exposure on MARR and adjustment time over 10 working days (two weeks) with two days of rest after …

Understanding the nervous system as an information processing machine: dense, nonspecific, canonical microcircuit architecture of inhibition in neocortex . . .
… as an information-processing machine. David Marr (1982) put forth the idea that in order to fully understand an information-processing machine one must understand it at three separate levels. The computational goal of the system must be understood separately from the algorithm by which it is …

Model for precise detection of bone edges
… can be calculated from the edge parameters. The Marr- Hildreth edge detector is used to detect the initial estimates for edge location. Precise estimates are obtained by using the facet model. The offset is then calculated and applied to these estimates.

Structural characterization of superbug proteins involved in regulating beta-lactam resistance
… Production of MexAB-OprM is controlled by the MarR family repressor, MexR, and several hyper-resistant strains of P. aeruginosa appear to involve mutations in either MexR or additional regulatory factors upstream of MexR. The allosteric effectors of MarR proteins are typically small …

Structure and Function of Bordetella Transcription Factor BpsR
… promoter is under repressive regulation by a MarR-family transcription factor Bordetella polysaccharide regulator, BpsR. BpsR binding inhibits expression of the bps locus, and leads to a decrease in polysaccharide available for biofilm formation. The goal of this thesis was to evaluate BpsR …

Hollywood Forever: Culture, Celebrity, and the Cemetery
… and Jr., Janet Gaynor, Mel Blanc, and Barbara La Marr, Hollywood Forever Cemetery in Los Angeles has long served as a tourist attraction and a site of public memory. The touristic visit or pilgrimage to the cemetery can be, like the visit to a sanctioned memorial, a means of stitching oneself into …

An Associative Memory Trace in the Cerebellar Cortex
… cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the response. Since their work, several studies have provided data that are consistent with …

The Journeys of Women in Local Elected Office: From Community Engagement to Making Meaningful Contributions
<p>Women remain underrepresented across every level of elected office in the United States. More than 30 years after the supposed “Year of the Woman,” women hold less than 30% of the elected positions in local, state, and federal office. In the past, researchers attributed the paucity of women in …

Comparison of Revvity soluble fms-like tyrosine kinase-1 and Placental Growth Factor methods on the DELFIA Xpress with Roche methods on the cobas e411: in a patient cohort with suspected preeclampsia as defined by NICE
Background: Measurement of angiogenic biomarkers; soluble fms-like tyrosine kinase-1 (sFlt-1) and placental like growth factor (PlGF), are increasingly used to support the diagnosis of preeclampsia in routine clinical practice. There are an increasing number of methods available for the analysis of …

Genetic diversity and pathogenicity of pea downy mildew (Peronospora viciae f. sp. pisi) in New Zealand : A thesis submitted in partial fulfilment of the requirements for the Degree of Master of Applied Science at Lincoln University
Downy mildew of peas is caused by the biotrophic pathogen Peronospora viciae f. sp pisi (Pvp) which occurs sporadically throughout temperate pea growing regions across the world. Severe infections can completely disrupt commercial production by reducing crop quality and yield; early season systemic …

A Nutritional Survey of Junior High School Pupils
This survey is the outgrowth of a common school problem of assisting the underweight child to meet the normal demands on his strength and to develop right attitudes and ideals for the health of the normal child. In one sense it is not a scientific experiment, in as much as the dietary control …

Self Injury in 1p36 deletion syndrome
Studies of 1p36 deletion syndrome have focused on physical characteristics with limited exploration of the behavioural phenotype. When behavioural features have been reported, self-injury and aggression are noted. This study aimed to describe these behaviours and investigate aetiology. The …

Unlocking the genetic potential of the root system, rhizosheath mucilage and microbiome of wheat (Triticum aestivum L.)
An increasing global population, projections of climates that will challenge sufficient crop production, and a detrimental use of fertiliser and pesticides mean that we need to increase the productivity of land currently under cultivation with minimal impact on the environment. Wheat is the second …

Environmental considerations in the design of base metals refineries : metals in riverine systems
There is a need for engineers involved in the desing of base metals refineries to understand the impacts of their design on the environment. Desing engineers should move their focus away from meeting effluent release concentration limits to identifying potential environmental impacts.

Functional significance of unique sequences in Mycobaterium smegmatis Ku proteins
… gene encoding a predicted zinc-dependent MarR family transcription factor. In addition, overexpression of Ku conferred zinc tolerance on E. coli. I speculate that zinc binding sites in Ku proteins from M. smegmatis and other mycobacterial species have been evolutionarily retained to …
