The Rate of Resorption of Different Regions of Residual Ridges in Complete Denture Wearers Dependent on the Region and the Period Following the Last Extraction. One Year Study.

Residual alveolar ridges (RR) show continual resorption after the loss of the natural dentition, resulting in reduction of the morphologic face height and counterclockwise rotation of the mandible, regardless of whether the dentures are worn or not. The aim of this study was to analyse residual ridge resorption (RRR) in 5 different regions of both jaws on the successive lateral cephalograms of 50 complete denture wearers and to correlate such changes with the number of years of edentia and the region where the last extraction was performed. The height of the residual ridges was measured on 5 different sites of the mandible and the maxillary RR using a calibrated grid. The results revealed that all the patients showed significant RRR in the one year period (p<0.01), which was 2.5x more in the mandible than in the maxilla. RRR was bigger in patients who had had their last extraction within a period of one year before receiving their dentures, than in patients who had extracted their teeth earlier (p<0.01). However, the rate of RRR was significantly higher (p<0.01) in the anterior regions of both jaws compared to distal regions (0.41 and 0.42 mm in the incisive/canine region: 0.2 and 0.17 mm in the premolar/ molar region for the maxilla 1.05 and 0.82 mm in the incisive/canine region : 0.27 and 0.11 in the premolar/ molar region for the mandible), even in patients where the last extraction was performed in the premolar region. It seems that the structure of the bone and strains in RR, due to loading from the dentures, may play a role, not only the period following extraction and the region of the last extraction

The Development of the Eocene Platform Carbonates from Wells in the Middle Adriatic Off-Shore Area, Croatia

In the Middle Adriatic deep off-shore wells the following sedimentary facies exist: fenestral and Charophyte limestone facies (X); facies of foraminiferal wackestone-packstone, ostracod marls and fine grained breccia conglomerate (A); facies of foraminiferal packstone-grainstone (B) and miliolidal mudstone-wackestone (C); facies of porous limestone?, grainstone? (Y); facies of fossiliferous mudstone-packstone (D); algal boundstone/bindstone and wackestone facies (E); facies of the foraminiferal mudstone-packstone (F); Nummulites-Discocyclina floatstone-packstone and grainstone-rudstone facies (G). The sediments were deposited close to the carbonate platform margin. Beds of facies X have an uncertain stratigraphic position; younger than the Cretaceous but older than the Cuisian. A transgressive sequence that is composed of facies A, B, C and Y was formed during the Cuisian, whereas the others belong to Lutetian (and Biarritzian). At the end of the Middle Eocene they were tectonically compressed and covered by flysch deposits. Good stratigraphic correlation between the wells along the Dinaric strike strongly suggests that the facies are laterally extensive in this direction. Perpendicular to the trend they are considerably reduced. Oil shows in the Kate-1 well originated from the Lower Cretaceous source rocks (evaporite complex)

Amoxicillin Biodegradation with Bacillus subtilis and Pseudomonas aeruginosa: Characterization of Relevant Degradation Products

The widespread use of antibiotics can result in the release of a large number of residues into the environment. In order to reduce the exposure risk, considerable research has been carried out in the field of antibiotic residues. We aim to explore the possibilities of antibiotic amoxicillin biodegradation in laboratory scale by adding microbiological cultures, Pseudomonas aeruginosa (Gram-negative) and Bacillus subtilis (Gram-positive), which are a type of bacteria that are commonly found in the environment, such as in soil and water. Apart from the degradation itself, special attention was paid to the identification of antibiotic residues. The biodegradation process was investigated, revealing a 99.2 % degradation efficiency at amoxicillin concentration of 0.2 mg mL–1, and four degradation products were identified. For reaction monitoring and identification of degradation products, UHPLC and LC-MS analyses were performed. Furthermore, to provide additional evidence, the products were independently synthesized and then compared spectrometrically with the obtained biodegradation products. These results could provide new aspects to the behavior of amoxicillin, and pave the way for further monitoring and studies of its residues in the environment.
