Characterization of the morphological evolution of MnS inclusions in free-cutting steel during heating

open access: yesJournal of Materials Research and Technology, 2022
The size, morphology and distribution of MnS inclusions in the sulfur bearing free-cutting steel are the key factors to determine the performance of the free-cutting steel. It is thus important to accurately characterize and control the morphology of the

The evolution of dystonia-like movements in TOR1A rats after transient nerve injury is accompanied by dopaminergic dysregulation and abnormal oscillatory activity of a central motor network

open access: yesNeurobiology of Disease, 2021
TOR1A is the most common inherited form of dystonia with still unclear pathophysiology and reduced penetrance of 30–40%. ∆ETorA rats mimic the TOR1A disease by expression of the human TOR1A mutation without presenting a dystonic phenotype.

High and Low Salt Intake during Pregnancy: Impact on Cardiac and Renal Structure in Newborns. [PDF]

open access: yesPLoS ONE, 2016
INTRODUCTION:Previous studies from our laboratory demonstrated that dietary salt overload and salt restriction during pregnancy were associated with cardiac and renal structural and/or functional alterations in adult offspring.

On the Applicability of Stereological Methods for the Modelling of a Local Plastic Deformation in Grained Structure: Mathematical Principles [PDF]

open access: yesCrystals, 2020
Analysis of systems and structures from their cross-sectional images finds applications in many branches. Therefore, the question of content, quantity, and accuracy of information obtained from various techniques based on cross-sectional views of structures is particularly important. Application of conventional techniques for two-dimensional imaging on

STEREOLOGICAL ESTIMATION OF SURFACE AREA FROM DIGITAL IMAGES

open access: yesImage Analysis and Stereology, 2011
A sampling design of local stereology is combined with a method from digital stereology to yield a novel estimator of surface area based on counts of configurations observed in a digitization of an isotropic 2- dimensional slice with thickness s.

Simulated blast overpressure induces specific astrocyte injury in an ex vivo brain slice model. [PDF]

open access: yesPLoS ONE, 2017
Exposure to explosive blasts can produce functional debilitation in the absence of brain pathology detectable at the scale of current diagnostic imaging.

STEREOLOGY: A HISTORICAL SURVEY

open access: yesImage Analysis and Stereology, 2017
Stereology is the science of geometric sampling, with applications to the statistical analysis of microstructures in biology and materials science. Subsidiary disciplines are image analysis, quantitative microscopy, and radiology.

Ulipristal acetate versus levonorgestrel-releasing intrauterine system for heavy menstrual bleeding: the UCON randomised controlled trial and mechanism of action study

open access: yesEfficacy and Mechanism Evaluation, 2023
Background Heavy menstrual bleeding affects one in four women and negatively impacts quality of life. The levonorgestrel-releasing intrauterine system is an effective long-term treatment but is discontinued by many due to unpredictable bleeding, or ...

ESTIMATION OF MINKOWSKI TENSORS FROM DIGITAL GREY-SCALE IMAGES

open access: yesImage Analysis and Stereology, 2014
It was shown in Svane (2014b) that local algorithms based on grey-scale images sometimes lead to asymptotically unbiased estimators for surface area and integrated mean curvature. This paper extends the results to estimators for Minkowski tensors.

GM-CSF induces noninflammatory proliferation of microglia and disturbs electrical neuronal network rhythms in situ

open access: yesJournal of Neuroinflammation, 2020
Background The granulocyte-macrophage colony-stimulating factor (GM-CSF) (or CSF-2) is involved in myeloid cell growth and differentiation, and, possibly, a major mediator of inflammation in body tissues. The role of GM-CSF in the activation of microglia
