MicroRNAs Regulate Ca 2+ Homeostasis in Murine Embryonic Stem Cells
(2023-07-28)MicroRNAs (miRNAs) are important regulators of embryonic stem cell (ESC) biology, and their study has identified key regulatory mechanisms. To find novel pathways regulated by miRNAs in ESCs, we undertook a bioinformatics ... -
Microstructural insight into inhalation powder blends through correlative multi-scale X-ray Computed Tomography
(2023-10-30)Dry powder inhalers (DPI) are important for topical drug delivery to the lungs, but characterising the pre-aerosolised powder microstructure is a key initial step in understanding the post-aerosolised blend performance. ... -
Microstructure Characterization and Battery Performance Comparison of MOF-235 and TiO 2 -P25 Materials
(2022-01-21)The growing interest in energy storage has led to the urgent need for the development of high-performance cathode electrodes. The commercialized materials MOF-235 and TiO2-P25 exhibit characteristics that may be suitable ... -
Microtubule dynamic instability: numerical simulation of microtubule transition properties using a Lateral Cap model
(1990)We present a numerical formulation for the dynamic instability of microtubules involving the stabilisation of growing microtubules by a single layer of tubulin-GTP, with GTP hydrolysis effectively coupled to tubulin-GTP ... -
Microvesicles and epithelial mesenchymal transition in the development of cancer
(2012-09-13)Microvesicles released by tumour cell lines are thought to play an important role in both extracellular matrix (ECM) invasion and evasion of the immune system. We have examined the role of MVs derived from a T cell line ... -
Microvesicles released constitutively from prostate cancer cells differ biochemically and functionally to stimulated microvesicles released through sublytic C5b-9
(2015-05-08)We have classified microvesicles into two subtypes: larger MVs released upon stimulation of prostate cancer cells, sMVs, and smaller cMVs, released constitutively. cMVs are released as part of cell metabolism and sMVs, ... -
Microvesicles released from Giardia intestinalis disturb host-pathogen response in vitro
(2017-03-31)Giardia intestinalis (G.I), is an anaerobic protozoan and the aetiological agent of giardiasis, a diarrhoea present worldwide and associated with poverty. G.I has a simple life cycle alternating between cyst and trophozoite. ... -
The mid-infrared environments of 6.7 GHz methanol masers from the Methanol Multi-Beam Survey
(2013-04-01)We present a study of the mid-infrared environments and association with star formation tracers of 6.7 GHz methanol masers taken from the Methanol Multi-Beam (MMB) survey. Our ultimate goal is to establish the mass of the ... -
A mid-infrared imaging catalogue of post-asymptotic giant branch stars
(2011-10-01)Post-asymptotic giant branch (post-AGB) stars are key objects for the study of the dramatic morphological changes of low- to intermediate-mass stars on their evolution from the AGB towards the planetary nebula stage. There ... -
Mid-infrared imaging of the dust shell around the post-asymptotic giant branch star HD 161796
(2003)We present mid-infrared (IR) images of HD 161796 (IRAS 17436+5003), taken with the OSCIR imager on the Gemini North Telescope, that resolve for the first time the thermal emission structure of the dust shell around this ... -
Mid-infrared photometry of cold brown dwarfs : diversity in age, mass and metallicity
(2010)We present new Spitzer Infrared Array Camera (IRAC) photometry of 12 very late-type T dwarfs: nine have [3.6], [4.5], [5.8], and [8.0] photometry and three have [3.6] and [4.5] photometry only. Combining this with previously ... -
Mid-infrared polarimetry and magnetic fields : an observing strategy
(2004)Linear polarimetry in the mid-infrared can be used to obtain magnetic field directions in astronomical sources. However, since the polarization can arise from emission and/or absorption from aligned grains, care is needed ... -
Mid-infrared spectroscopy of candidate AGN-dominated submillimeter galaxies
(2010)Spitzer spectroscopy has revealed that ~80% of submm galaxies (SMGs) are starburst (SB) dominated in the mid-infrared. Here we focus on the remaining ~20% that show signs of harboring powerful active galactic nuclei (AGN). ... -
Mid-IR spectra of type Ia SN 2014J in M82 spanning the first 4 months
(2015-01-10)We present a time series of 8-13 μm spectra and photometry for SN 2014J obtained 57, 81, 108, and 137 days after the explosion using CanariCam on the Gran Telescopio Canarias. This is the first mid-IR time series ever ... -
Mid-Victorian Britain
(Shire, 2011)The middle years of Queen Victoria's reign saw huge social changes, with the rise of the middle classes, the introduction of compulsory education and the growth of the labour movement. The Great Exhibition brought a taste ... -
A Middle Manager's Response to Strategic Directives on Integrated Care in an NHS Organisation: Developing a Different Way of Thinking about Prejudice
(University of Hertfordshire, 2013-07-29)This thesis examines a middle manager’s response to strategic directives on integrated care in a National Health Service (NHS) organisation and the development of an awareness of prejudice that acknowledges its relationship ...
