Po-ju Chia-LaiAnna OrlowskaSarah Al-MaawiAndre DiasYunxin ZhangXuejiu WangNiklas ZenderRobert SaderC. James KirkpatrickShahram Ghanaati
This study examines the permeability and barrier capacity of a sugar cross-linked resorbable collagen membrane ex vivo and in vivo. In an ex vivo study, injectable platelet-rich fibrin (i-PRF), a peripheral blood-derived human leukocyte-and-platelet-rich plasma was used to analyze membrane permeability. […]

In vivo cellular reactions to different biomaterials—Physiological and pathological aspects and their consequences

Seminars in Immunology, DOI: 10.1016/j.smim.2017.06.001 (2017).
Sarah Al-Maawi, Anna Orlowska, Robert Sader, C. James Kirkpatrick, Shahram Ghanaati
Biomaterials are widely used in guided bone regeneration (GBR) and guided tissue regeneration (GTR). After application, there is an interaction between the host immune system and the implanted biomaterial, leading to a biomaterial-specific cellular reaction. The present review focuses on […]

Frankfurt: Course on toxicology and molecular biology techniques

3-5 December 2015
Core training course
The course will cover such topics as methodology, models, and statistical estimation and hypothesis tests.
Introductory course on toxicological evaluation of materials, basic cell and molecular biology techniques
Given the large differences in background between experimental and theoretical/computational ESRs, training courses will aim to highlight these two areas at different levels.
Thursday, 3th of December […]

ESR12-F: Toxicity of nano-objects on human cells models

In-vitro experiments on living cells, toxicology studies
Contact
Anna Orlowska
Objectives
Main objective is to compare, validate and corroborate the findings of the interaction of the nano-objects synthesised by the network to actual human cell models with the findings observed with the lipid membrane model systems.
Tasks and methodology
Recruited ESR will obtain experience in toxicity, cell- and molecular biological methodology […]
