Helicobacter pylori susceptibility testing by disc diffusion [PDF]
Journal of Antimicrobial Chemotherapy, 2002 The bacterium Helicobacter pylori is found in c. 40% of the population and is responsible for the development of duodenal disease. Triple treatment with a proton-pump inhibitor or bismuth salt plus two antibiotics is now commonplace in all patients diagnosed.

Diffusion of radial action in a galactic disc [PDF]
Astronomy & Astrophysics, 2020 Context. The stellar migration of the galactic disc stars has been invoked to explain the dispersion of stellar metallicity observed in the solar neighbourhood. Aims. We seek to identify the dynamical mechanisms underlying stellar migration in an isolated galaxy disc under the influence of a bar.

Mixing and diffusion in protoplanetary disc chemistry [PDF]
Astronomy & Astrophysics, 2022 We develop a simple iterative scheme to include vertical turbulent mixing and diffusion in PRODIMO thermo-chemical models for protoplanetary discs. The models are carefully checked for convergence towards the time-independent solution of the reaction-diffusion equations, as, for example, used in exoplanet atmosphere models. A series of five TTauri disc

On disc protoplanet interactions in a non-barotropic disc with thermal diffusion [PDF]
Astronomy & Astrophysics, 2008 We study the disc planet interactions of low-mass protoplanets embedded in a circumstellar disc. We extend the standard theory of planet migration from the usual locally isothermal assumption to include non-barotropic effects, focusing on the validity of linear theory.

Finite Element Study of Oxygen Diffusion in the Intervertebral Disc
Advances in Bioengineering, 2000 Abstract The intervertebral disc consists of a water-rich extra-cellular matrix which is synthesized and maintained by its cells. The disc is the largest avascular tissue in the body with its cells lying as much as 8mm away from the blood supply.

Computational investigation of sulphate diffusion into the dog disc
2011 18th Iranian Conference of Biomedical Engineering (ICBME), 2011 We proposed a model to investigate the transient diffusion of drug (sulphate) into the intervertebral disc. Using finite element method, drug diffusion was simulated and the concentration of diffused drug in each region of disc including Nucleus pulpous (NP), Inner annulus fibroses (IA), and Outer annulus fibroses (OA) was measured.

The effect of sustained compression on oxygen metabolic transport in the intervertebral disc decreases with degenerative changes. [PDF]
PLoS Computational Biology, 2011 Intervertebral disc metabolic transport is essential to the functional spine and provides the cells with the nutrients necessary to tissue maintenance. Disc degenerative changes alter the tissue mechanics, but interactions between mechanical loading and ...

Ankara Üniversitesi Tıp Fakültesi Mecmuas, 2008 Purpose: To evaluate the correlation of the diffusion values in lumbar intervertebral discs with disc degeneration and age.Materials and Methods: Diffusion-weighted imaging of the lumbar spine was performed in fifty patients. ADC values were recorded for each disc. All discs were visually as being normal or as showing at least one of two MR findings of
