Intracellular accumulation of high levels of gamma-aminobutyrate by Listeria monocytogenes 10403S in response to low pH: uncoupling of gamma-aminobutyrate synthesis from efflux in a chemically defined medium
(American Society for Microbiology, 2010-06)It is well established that the glutamate decarboxylase (GAD) system is central to the survival of Listeria monocytogenes at low pH, both in acidic foods and within the mammalian stomach. The accepted model proposes that ... -
Introduction to the special issue on stability under finite deformation
(Oxford University Press, 2010)In the botanical gardens of Grenoble, France, there is small bridge, just a few metres long, made of pre-stressed concrete. The bridge dates back to 1855 and is thought to be the oldest manufactured pre-stressed structure ... -
Investigating native state fluorescence emission of Immunoglobulin G using polarized Excitation Emission Matrix (pEEM) spectroscopy and PARAFAC
(Elsevier, 2018-12-20)Intrinsic fluorescence spectroscopy (IFS) measurements for protein structural analysis can be enhanced by the use of anisotropy resolved multidimensional emission spectroscopy (ARMES). ARMES attempts to overcome the ... -
Investigating the solid state hosting abilities of homo- and hetero-valent [Co-7] metallocalix[6]arenes
(RSC, 2012)A family of homo-valent [Co(II)(7)(OH)(6)(L-1)(6)](NO3)(2)(1), [(MeOH)(2)subset of Co(II)(7)(OH)(6)(L-1)(6)](NO3)(2) (2) (where L1H = 2-iminomethyl-6-methoxyphenol) and hetero-valent [(NO3)(2)subset of Co(III)Co(II)(6)(O ... -
Investigating tryptophan quenching of fluorescein fluorescence under protolytic equilibrium
(2009)Fluorescein is one of most used fluorescent labels for characterizing biological systems, such as proteins, and is used in fluorescence microscopy. However, if fluorescein is to be used for quantitative measurements involving ... -
An investigation into the use of MMCTP to tune accelerator source parameters and testing its clinical application.
(2013)This paper presents an alternative method to tune Monte Carlo electron beam parameters to match measured data using a minimal set of variables in order to reduce the model setup time prior to clinical implementation of the ... -
Investigation of depth-resolved nanoscale structural changes in regulated cell proliferation and chromatin decondensation
(2013)We present depth-resolved spatial-domain low-coherence quantitative phase microscopy, a simple approach that utilizes coherence gating to construct a depth-resolved structural feature vector quantifying sub-resolution axial ... -
Investigation of nanoscale structural alterations of cell nucleus as an early sign of cancer
(BioMed Central, 2014)Background: The cell and tissue structural properties assessed with a conventional bright-field light microscope play a key role in cancer diagnosis, but they sometimes have limited accuracy in detecting early-stage cancers ... -
Investigation of non-covalent interactions of metal complexes with DNA in cell-free systems
(Schweizerische Chemische Gesellschaft, 2017-03-01)Non-covalent interactions of metallo compounds with DNA range from the simple, unspecific electrostatic binding of a positively charged metal complex to the sequence-selective recognition of DNA binding sites due to shape, ... -
An investigation of the Eigenvalue Calibration Method (ECM) using GASP for non-imaging and imaging detectors
(Springer Verlag, 2016-02)Polarised light from astronomical targets can yield a wealth of information about their source radiation mechanisms, and about the geometry of the scattered light regions. Optical observations, of both the linear and ... -
Investigation of the formation of drug-drug cocrystals and coamorphous systems of the antidiabetic drug gliclazide
(Elsevier, 2019-02-23)The antidiabetic drug gliclazide (GLZ) has a slow absorption rate and a low bioavailability due to its poor solubility. GLZ is often prescribed along with an antihypertensive, as many diabetic patients have coexistent ... -
Investigations of the magnetospheric plasma distribution in the vicinity of a pulsar - I Basic formulation
(2008)The magnetospheric plasma distribution in the vicinity of a pulsar at various inclination angles is investigated using a new relativistic, parallel 3D Particle-In-Cell (PIC) code DYMPHNA3D. DYMPHNA3D uses a superposition ... -
The invisible barrier to safe textile recycling
(Frontiers Media, 2022-06-14)Presence of certain chemical additives (e.g. halogenated flame retardants, perfluoroalkyl substances, and phthalates) could hinder textile recycling operations as their presence renders end-of-life materials as “hazardous” ... -

The isolation of strains of Bacillus subtilis showing improved plasmid stability characteristics by means of selective chemostat culture
(1988-03-23)A PUB 110-derived plasmid encoding chloramphenicol resistance, kanamycin resistance and high-temperature alpha-amylase showed a high degree of segregational instability when inserted into Bacillus subtilis. In an attempt ... -
John Todd and the development of modern numerical analysis
(2012)The purpose of this article is to mark the centenary of the birth of John Todd, a pioneer in the fields of numerical analysis and computational science. A brief account is given of his early life and career, and that of ... -
The June 2008 flare of Markarian 421 from optical to TeV energies
(2008)We present optical, X-ray, high energy ($\lessapprox 30$ GeV) and very high energy ($\gtrapprox 100$ GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken between 2008 May 24 and June 23. A high energy ... -
Kernel principal component analysis residual diagnosis (KPCARD): an automated method to remove cosmic ray artefacts in Raman spectra.
(2016)A new, fully automated, rapid method, referred to as kernel principal component analysis residual diagnosis (KPCARD), is proposed for removing cosmic ray artifacts (CRAs) in Raman spectra, and in particular for large Raman ... -
Kinematics of the Broad Line Region in M81
(2007)A new model is presented which explains the origin of the broad emission lines observed in the LINER/Seyfert nucleus of M81 in terms of a steady state spherically symmetric inflow, amounting to 1 x 10^-5 Msun/yr, which is ... -
