Optimal management of emergency surgical patients represents one of the major health challenges worldwide. Emergency general surgery (EGS) was identified as multidisciplinary surgery performed for traumatic and non-traumatic acute conditions during the same admission in the hospital. EGS represents the easiest viable way to provide affordable and high-quality level of care to emergency surgical...
The aim of this study was to determine size, shape and position of the image layer by evaluation of the radiographic image formation in different anatomic positions. A customized phantom was made of a rectangular acrylic plate measuring 14 cm² and 0.3 cm thick, with holes spaced 0.5 cm away and arranged in rows and columns. Each column was separately filled with 0.315 cm diameter metal spheres ...
The long-term success of an implant may be dependent on the production of a stable basement membrane and it may be desirable to reproduce the structure of healthy Bruch’s membrane. We hypothesise that the substrate surface chemistry will influence RPE extracellular matrix (ECM) production. The aim of this work was to investigate the distribution of ECM proteins produced by primary human RPE cel...
The objective of this in vitro study was to evaluate demineralization around restorations. Class V preparations were made on the buccal and lingual surfaces of each tooth. TPH (Group 1), Fuji II LC (Group 2), Tetric (Group 3), Dyract (Group 4), GS 80 (Group 5) and Chelon Fil (Group 6) were randomly placed in equal numbers of teeth. The teeth were submitted to a pH-cycling model associated with ...
The factors involved in evaluations of effects of volatile organic compound (VOC) and oxides of nitrogen emissions from motor vehicles on ground-level ozone are reviewed. The chemical basis for ozone formation, the computer models and chemical mechanisms used for predicting ozone impacts, and methods for quantifying differences among VOCs in their ozone impacts, are discussed. It is recommended...
During the last years many authors have characterized the produced formation waters (PFWs) with respect to chemical compounds and toxicity. Most of data are related to PFWs collected on offshore platform after treatment process. The available results showed that the particulate phase had an influence on PFW toxicity. Assuming the toxicity of PFWs treated on platform, the aim of this paper is to...
Acquired enamel pellicle (AEP) is a protein film that forms on the enamel surface of teeth by selective adsorption of proteins and peptides present in the mouth. This protein film forms the interface between enamel and the damage oral biofilm, which modulates the attachment of bacteria found in oral biofilm. The overall goal of this study was to gain insight into the biological formation of the...
Evaluative conditioning (EC) experiments and impression formation experiments study factors that influence evaluation. Despite large overlap between these two research traditions, they often operate in parallel without attention to findings and theories from the other line of research, risking redundancy. We suggest reintegrating EC research into impression formation as the branch of research t...
