BACKGROUND Recombinant proteins are usually required in laboratories interested in the protein but not in the production process itself. Thus, technical equipment which is easy to handle and straight forward protein production procedures are of great benefit to those laboratories. Companies selling single use cultivation bags and bioreactors are trying to satisfy at least part of these needs. H...

This controlled clinical trial evaluated the 2-year clinical performance of a one-bottle etch-and-rinse adhesive and resin composite system (Excite/Tetric Ceram) compared to a resin-modified glass ionomer cement (RMGIC) (Vitremer/3M) in non-carious cervical lesions. Seventy cervical restorations (35 resin composite - RC- restorations and 35 RMGIC restorations) were placed by a single operator i...

Oxygen respiration rates in pelagic environments are often difficult to quantify as the resolutions of our methods for O2 concentration determination are marginal for observing significant decreases during bottle incubations of less than 24 hours. Here we present the assessment of a new highly sensitive method, that combine Switchable Trace Oxygen (STOX) sensors and all-glass bottle incubations...

The environmental impacts of global food supply chains are growing with the need for their measurement and management. This paper explores the operations of a global supply chain for extra-virgin olive oil (EVOO) according to a life cycle assessment (LCA) methodology. The LCA assessment methodology is applied to determine the environmental impact categories associated with the bottled EVOO life...

The diffusion of CO2 through macro- and micro-agglomerated cork stoppers for sparkling wine was studied by a manometric technique. effective coefficients each part the stopper (cork body, disc adhesives) were determined first time. results show that small particle size along with high adhesive content level compression favor gas barrier properties stopper. Although discs placed at one end prese...

Using the BacT/Alert automated system, we conducted a 1-year retrospective study on blood cultures, focusing on the relevance of routine use of the anaerobic bottle. The rate of patients with positive blood cultures was 19.7%. Among these, 13.5% had a positive anaerobic bottle in the absence of any aerobic bottle, and 2/3 of these grew with nonobligate anaerobes. These patients were hospitalize...

Rectal foreign bodies present the modern surgeon with a difficult management dilemma. Reluctance to seek medical help and to provide details about the incident often makes diagnosis difficult. Management of these patients may be challenging, as presentation is usually delayed after multiple attempts at removal by the patient themselves. Here we present a case of 35 year old male who presented i...

Blood was cultured in two vacuum bottles containing Columbia broth. Filtered air was admitted to one bottle (aerobic); the unvented bottle was considered anaerobic. Cultures were incubated at 35 C until growth occurred or for at least 7 days. Of 744 organisms isolated, 50% were isolated from both bottles, 30% from the aerobic bottle only, and 20% from the anaerobic bottle only. These results in...

With the European Green Deal, importance of recycled products and materials has increased. Specifically, for PET bottles, a high content material (rPET) is demanded by industry consumers. This study was carried out in lab environment replicating real-life industrial processes, to investigate possible impacts on rPET quality over eleven recycling loops, aiming use amounts repetitively. A cycle i...
