[The influence of VEGF inhibitors on corneal endothelium after injection into the anterior chamber in a porcine eye model].

Background: The injection of antiangiogenic agents, such as ranibizumab (Lucentis®) and bevacizumab (Avastin®) into the anterior chamber of the eye represents a suitable alternative for treating neovascular glaucoma by reducing intraocular pressure.

Objectives: As the antiangiogenic substances are in direct contact with the sensitive corneal endothelium, the aim of this study was to show the effects of intracameral injection of ranibizumab and bevacizumab on this cell layer.

Methods: Each injection consisted of 50 µl containing either ranibizumab (0.

XTT assay of ex vivo saliva biofilms to test antimicrobial influences.

Objective: Many dental diseases are attributable to biofilms. The screening of antimicrobial substances, in particular, requires a high sample throughput and a realistic model, the evaluation must be as quick and as simple as possible. For this purpose, a colorimetric assay of the tetrazolium salt XTT (sodium 3'-[1-[(phenylamino)-carbony]-3,4-tetrazolium]-bis(4-methoxy-6-nitro)benzene-sulfonic acid hydrate) converted by saliva biofilms is recommended.

Development of a method for magnetic labeling of platelets.

Unlabelled: Platelets play a dominant role in the pathogenesis of bleeding disorders and cardiovascular pathology (e.g., myocardial infarction).

Antimicrobial efficacy of non-thermal plasma in comparison to chlorhexidine against dental biofilms on titanium discs in vitro - proof of principle experiment.

Aim: Dental biofilms play a major role in the pathogenesis of peri-implant mucositis. Biofilm reduction is a pre-requisite for a successful therapy of peri-implant mucosal lesions. In this study, we evaluated the effect of three different plasma devices on the reduction of Streptococcus mutans (S.

Characterization of the global impact of low temperature gas plasma on vegetative microorganisms.

Plasma medicine and also decontamination of bacteria with physical plasmas is a promising new field of life science with huge interest especially for medical applications. Despite numerous successful applications of low temperature gas plasmas in medicine and decontamination, the fundamental nature of the interactions between plasma and microorganisms is to a large extent unknown. A detailed knowledge of these interactions is essential for the development of new as well as for the enhancement of established plasma-treatment procedures.
