Decontamination of a barrier facility using microisolator cages and provisional partitioning
2007
In 2000, the authors found endemic infections of mouse hepatitis virus, minute virus of mice, Syphacia obvelata, and Myobia musculi among mice in a large barrier facility at the University of Mainz. To eliminate the infections, they subdivided the facility into two distinct hygiene units. However, architectural constraints made it impossible to completely separate the HVAC systems of both hygiene units and to establish adequate personnel locks. To compensate for these suboptimal barrier conditions of the two newly established units, the authors replaced the open-top caging and open-servicing system with filter-top cages that were manipulated in cage-changing stations. The authors then depop…
Aspects Regarding the use of Biodegradable Ecological Detergents in the Decontamination of R.B.C.
2021
Abstract Ecological decontamination solutions are widely used in various fields of activity especially in this period when many countries in the world are implementing at macro level the concept of sustainable development. The use of detergents in the process of R.B.C. decontamination led to in-depth analyzes of the absorbent properties of organic products. These products have the ability to partially or completely remove detergents from wastewater resulting from decontamination, thus reducing pollution by environmental factors. The present paper aimed at the comparative analysis of the absorbent properties of a power plant ash and diatomite ore. Also, some experiments were performed on the…
Green strategies for decontamination of analytical wastes
2010
Within the paradigm of green analytical chemistry, we discuss the different options for cleaning analytical wastes in the literature, paying special attention to on-line recycling of solvents, degradation of toxic compounds and trace-element passivation. The objective of this review is to present and to evaluate critically suitable methodologies that can be incorporated into analytical methods in order to reduce or to avoid the generation of toxic wastes, which could cumulate in the laboratory and have to be managed outside, so increasing the risks and the cost of analysis.
Efficacy of four cleaning solutions for the decontamination of selected cytotoxic drugs on the different surfaces of an automated compounding system
2018
The automated aseptic preparation of ready-to-administer antineoplastic drug solutions with robotic systems reduces the risk of occupational exposure. However, the surfaces in the preparation area of the robot are to be cleaned by wiping with an appropriate cleaning solution. The aim of the study was to evaluate the cleaning efficacy of four cleaning solutions on four surface materials installed in the APOTECAchemo robot. Predefined amounts of cisplatin (Cis), 5-fluorouracil (5-FU), and cyclophosphamide (CP) were intentionally spread on test plates made of stainless steel, aluminium, polyoxymethylene, and polycarbonate just as installed in the robotic system APOTECAchemo. After drying, the …

Intake, decontamination and legislation of fumonisins in foods
2004
Fumonisins (FB) are mycotoxins synthesized mainly by different species of the genus Fusarium with different toxicological effects in humans and animals and associated to esophageal cancer in different countries. This review gives an overview about the intake of fumosins from foods with a careful attention for people with gluten intolerance, celiac or Duhring's disease, infants and alcohol consumers. Furthermore, a section on decontamination is focused on physical, chemical and biological methods. Finally, the legislation of fumonisins in foods in different countries is reviewed.
Disposable chlorine dioxide wipes for high-level disinfection in the ENT department: A systematic review
2020
Abstract Background Nasopharyngoscope reprocessing methods should be effective, rapid and reproducible with moderate cost. Tristel Trio Wipes system (TTWS) is a manual reprocessing method based on chlorine dioxide that has lately emerged in ENT department. This review aims to collect evidence on this system. Methods The PubMed, Web of Science and Cochrane Library databases were searched for all the studies on TTWS or one of its components. Data were grouped according to the study type. Results Ten articles were included in the review. TTWS ensured high-level disinfection in laboratory and clinical setting. Although the limitations of the manual systems, TTWS proved to be faster than automat…
Effect of simulated CO2and GaAlAs laser surface decontamination on temperature changes in Ti-plasma sprayed dental implants
2002
Background and Objective To investigate and compare temperature elevations at the implant-bone interface during simulated implant surface decontamination with a CO2 and a GaAlAs laser. Study Design/Materials and Methods Stepped cylinder implants (Frialit 2® Friadent GmbH, Mannheim, Germany) with a Titanium plasma sprayed surface were inserted into bone blocks cut from pig femurs. An artificial periimplant bone defect provided access for laser irradiation in the coronal third. Both lasers were operated at 1.0–2.5 W in the cw-mode. The bone block was placed into a 37°C water bath in order to simulate in vivo thermal conductivity and diffusitivity of heat. K-type thermocouples connected to a d…
Bacterial inactivation/sterilization by argon plasma treatment on contaminated titanium implant surfaces: in vitro study
2015
Background: Surface treatment by argon plasma is widely used as the last step of the manufacturing process of ti- tanium implant fixtures before their sterilization by gamma rays. The possibility of using such a technology in the daily clinical practice is particularly fascinating. The aim of the present study was to assess the effects of the argon plasma treatment on different titanium implant surfaces previously exposed in vitro to bacterial contamination. Material and Methods: Sterile c.p. titanium implant discs with turned (T, Sa: 0.8μm), sandblasted/acid-etched (SAE, Sa: 1.3μm) and titanium plasma sprayed (TPS, Sa: 3.0μm) surface were used in this study. A strain of Ag- gregatibacter a…
