In a 2.5-year-long environmental engineering experiment in the By Fjord, surface water was pumped into the deepwater where the frequency of deepwater renewals increased by a factor of 10. During the experiment, the deepwater became long-term oxic, and nitrate became the dominating dissolved inorganic nitrogen component. The amount of phosphate in the water column decreased by a factor of 5 due ...
Streptococcal toxic shock syndrome (STSS) caused by Streptococcus pyogenes is a clinical condition with a high mortality rate despite modern intensive care. A key feature of STSS is excessive plasma leakage leading to hypovolemic hypotension, disturbed microcirculation and multiorgan failure. Previous work has identified a virulence mechanism in STSS where M1 protein of S. pyogenes forms comple...
The objective of this study was to compare the sealing ability of ActiV GP/glass ionomer (GI) sealer (Brasseler USA, Savannah, GA), Resilon/Epiphany (Pentron Clinical Technologies, Wallingford, CT), and gutta-percha (GP)/AH Plus (Dentsply Maillefer, Tulsa, OK). Seventy-three human single-rooted teeth were randomly divided into three test groups (20 canals each) and two control groups (5 positiv...
Introduction: The aim of this study was to evaluate the sealing ability of Bioactive glass (BG) and Bioactive glass-Hydroxyapatite (BG-HA) in comparison to Mineral Trioxide Aggregate (MTA). Methods: The sealing ability of Bioactive glass and Bioactive glass-hydroxyapatite mixed with glass ionomer cement and Mineral Trioxide Aggregate used as retrograde filling material was assessed by bacterial...
Coronal restorations and posts can positively influence the long-term prognosis of teeth following root canal therapy. Final sealing the canal by placing an appropriate post and core will minimize leakage of oral fluids and bacteria into the periradicular area and is recommended as soon as possible after completion of root canal filling. Glass ionomer or MTA placed over the residual root canal ...
impact of plant extracts and antibiotics on biofilm formation of clinical isolates from otitis media
conclusions the bacterial isolates exhibited strong biofilm formation potential, while the extracts of acacia arabica significantly inhibited biofilm formation among the isolates and, therefore, could be executed in the development of cost-effective biofilm inhibitor medicines. results pseudomonas aeruginosa (kc417303-05), staphylococcus hemolyticus (kc417306), and staphylococcus hominis (kc417...
Introduction & Objective: The success of root canal therapy depends on the ability to establish and maintain an apical seal, therefore, it is important, that post space preparation do not disrupt the integrity of the apical seal. The purpose of this study was to compare the effect of immediate versus delayed post space preparation on the apical seal using AH26 and Dorifil sealers. Materials...
A release of acid soluble constituents that absorb at 260 mp occurs during the incubation of suspensions of Escherichia coli H (1)) Pseudomonas aeruginosa (2)) or Lactobacillus arabinosus (3) in buffers. Lysogenic E. coli strain Klz as well as nonlysogenie E. coli strains B and B/r excrete ultraviolet-absorbing substances during growth in media deficient in glucose, and a methionine-requiring a...
