Isolation and characterization of extracellular vesicles and future directions in diagnosis and therapy
(2023-01-13)Extracellular vesicles (EVs) are a unique and heterogeneous class of lipid bilayer nanoparticles secreted by most cells. EVs are regarded as important mediators of intercellular communication in both prokaryotic and ... -
Isolation and characterization of genes induced during non-host resistance to Polymyxa spp

The isolation and culture of cucumber mesophyll protoplasts
(1975-03-01)Large numbers of viable protoplasts were obtained from the first leaves of two cultivars of cucumber, Cucumis sativus L. cv. Ashley and China. Cell wall regeneration was observed in liquid culture within 3 days of isolation, ... -
Isolation of an RNA-dependent RNA polymerase from Nicotiana benthamiana plants infected with Tobacco necrosis virus (strain D) and template-dependent transcription of its satellite, Satellite tobacco necrosis virus (strain C) RNA
(2001-04-01)Partially purified RNA-dependent RNA polymerase activity isolated from Nicotiana benthamiana plants infected with Tobacco necrosis virus strain D (TNV-D) is capable of template-dependent synthesis of Satellite tobacco ... -
Isolation of microcrystalline cellulose from wood and fabrication of polylacticacid (PLA) based green biocomposites
(2024-08-02)An innovative microcrystalline cellulose (MCC) natural fibre powder-reinforced PLA biocomposite was investigated using the hand lay-up technique. The polymer matrix composite (PMC) samples were prepared by varying the weight ... -
Isolation of microvesicles and exosomes by microfiltration and estimation of normal reference range in blood plasma.
(2012-09-13)Current protocols for the isolation of microvesicles (MVs) and exosomes, which in the main focus on differential centrifugation, vary considerably (1). In an attempt to set a new standard, we describe a filtration protocol ... -

Isometamidium in goats : disposition kinetics, mammary excretion and tissue residues
(1990-09)The pharmacokinetics of the antitrypanosomal drug isometamidium were studied in lactating goats after intravenous and intramuscular administration at a dose of 0.5 mg/kg body weight, in a crossover design at an interval ... -
Isometamidium in pigs : disposition kinetics, tissue residues and adverse reactions
(1991-01)The disposition and adverse effects of the anti-trypanosomal drug isometamidium in pigs were evaluated. Following intramuscular administration of the drug at doses of 0.5, 15 and 35 mg kg-1, the drug was rapidly absorbed ... -
Isometric and isovelocity contractile performance of red muscle fibres from the dogfish Scyliorhinus canicula
(2002-06)Maximum isometric tetanic force produced by bundles of red muscle fibres from dogfish, Scyliorhinus canicula (L.), was 142.4+/-10.3 kN m(-2) (N=35 fibre bundles); this was significantly less than that produced by white ... -
Isopimaric acid from Pinus nigra shows activity against multidrug-resistant and EMRSA strains of Staphylococcus aureus
(2005)The diterpene isopimaric acid was extracted from the immature cones of Pinus nigra (Arnold) using bioassay-guided fractionation of a crude hexane extract. Isopimaric acid was assayed against multidrug-resistant (MDR) and ... -
Isospectral mapping for quantum systems with energy point spectra to polynomial quantum harmonic oscillators
(2021-03-15)We show that a polynomial Hˆ(N) of degree N of a harmonic oscillator hamiltonian allows us to devise a fully solvable continuous quantum system for which the first N discrete energy eigenvalues can be chosen at will. In ... -
Isothermal dust models of Herschel-ATLAS galaxies
(2013-12)We use galaxies from the Herschel-ATLAS (H-ATLAS) survey, and a suite of ancillary simulations based on an isothermal dust model, to study our ability to determine the effective dust temperature, luminosity and emissivity ... -
An Isotonic Model of Neuron Swelling Based on Co-Transport of Salt and Water
(2023-02-07)Neurons spend most of their energy building ion gradients across the cell membrane. During energy deprivation the neurons swell, and the concomitant mixing of their ions is commonly assumed to lead toward a Donnan equilibrium, ... -
Isovalues : A Useful Tool for Marketing Theorists and Practitioners?

The issue of moral distress in community pharmacy practice : background and research agenda
(2015-10)OBJECTIVES: Moral distress arises from situations in which the individual identifies the morally right action required, but feels unable to act accordingly due to organisational constraints within the work place. Research ... -

Issues of reliability and validity in the measurement of challenging behaviour (behavioural difficulties) in learning disability: a discussion of implications for nursing research and practice
(1996)The purpose of this paper is to contribute to the debate on issues related to the reliability and validity of measurement of challenging behaviour (behavioural difficulties) in learning disability. A number of practical, ...
