Effects of Two Different Methods of Non‐Surgical Periodontal Therapy on Patient Perception of Pain and Quality of Life: A Randomized Controlled Clinical Trial
Authors: Åslund Madeleine , Suvan Jean , Moles David R. , D'Aiuto Francesco , Tonetti Maurizio S. 
Published: June 2008

Background: The purpose of this study was to investigate the effect of two modes of delivery of non‐surgical periodontal therapy on patient experience of pain and oral health–related quality of life (OHQoL).Methods: Fifty‐nine patients with mild to moderate periodontitis received non‐surgical therapy using a piezo‐ceramic device (n = 30) or curets (n = 29). Periodontal examinations were carried out at baseline and 8 weeks following therapy. Subjects completed the short‐form McGill pain questionnaire, visual analog scales regarding sensitivity and satisfaction, and the United Kingdom OHQoL questionnaire (OHQoL‐UK) at baseline, treatment, and 1, 4, and 8 weeks.Results: Both groups showed improvements in clinical parameters with no significant differences between the groups. Pain scores and OHQoL‐UK showed no significant differences between the groups. After treatment, OHQoL‐UK scores improved from an initially negative effect on quality of life to a level of no effect. Differences in sensitivity scores between the groups were statistically significant at 1 week (P = 0.011), 4 weeks (P = 0.005), and 8 weeks (P = 0.025), favoring the use of the piezo‐ceramic device.Conclusions: In mild to moderate periodontitis, therapy had a small positive impact on pain and OHQoL‐UK scores. These data support the concept that periodontitis may negatively affect a patient's quality of life and that treatment may improve it.

Published: June 2008

Background: Vascular endothelial growth factor (VEGF) is a macromolecule of importance in inflammation that has been implicated in periodontitis. The aims of this study were to investigate VEGF expression during the progression of periodontal disease and to evaluate the effect of a preferential cyclooxygenase (COX)‐2 inhibitor meloxicam on VEGF expression and alveolar bone loss in experimentally induced periodontitis.Methods: A total of 120 Wistar rats were randomly separated into groups 1 (control) and 2 (meloxicam, 3 mg/kg/day, intraperitoneally, for 3, 7, 14, or 30 days). Silk ligatures were placed at the gingival margin level of the lower right first molar of all rats. VEGF expression was assessed by reverse transcription‐polymerase chain reaction (RT‐PCR), Western blot (WB), and immunohistochemical (IHC) analyses. The hemiarcades were processed for histopathologic analysis. RT‐PCR and WB results were submitted to analysis of variance, the Tukey test, and Pearson correlation analysis (P <0.05).Results: A reduction in alveolar bone resorption was observed in the meloxicam‐treated group compared to the control group at all periods studied. There was a positive correlation between COX‐2 mRNA and VEGF mRNA in the gingival tissues and periodontal disease (R = 0.80; P = 0.026). Meloxicam significantly reduced the increased mRNA VEGF expression in diseased tissues after 14 days of treatment (P = 0.023). Some alterations in VEGF receptor 1 mRNA expression were observed, but these were not statistically significant. VEGF protein expression in WB experiments was significantly higher in diseased sites compared to healthy sites (P <0.05). After 14 days of treatment with meloxicam, an important decrease in VEGF protein expression was detected in diseased tissues (P = 0.08). Qualitative IHC analysis revealed that VEGF protein expression was higher in diseased tissues and decreased in tissues from rats treated with meloxicam.Conclusions: The present data suggest an important role for VEGF in the progression of periodontal disease. Systemic therapy with meloxicam can modify the progression of experimentally induced periodontitis in rats by reducing VEGF expression and alveolar bone loss.

Published: June 2008

Background: Adequate bone volume is imperative for the osseointegration of endosseous implants, but postextraction resorption and remodeling may challenge implant placement. The use of bone biomaterials has been advocated to fill extraction sites and to enhance primary implant stability during osseointegration. The objective of the case series was to evaluate bone formation histologically and biomechanically in extraction sites following implantation of three commercially available bone biomaterials to compare their ability to allow guided bone regeneration.Methods: Thirty‐six periodontally involved teeth were extracted from eight healthy non‐smoking subjects. At least two bone biomaterials, a synthetic sponge based on polylactic–polyglycolic acid technology (FIS), bovine porous bone mineral (BPBM), or a natural coral derivative physically and chemically transformed into a calcium carbonate ceramic (COR), and one non‐grafted control were applied to the extraction sockets within each subject and were covered by an expanded polytetrafluoroethylene device. The devices were removed after 2 months, and trephine biopsies were obtained from each site 4 months later. At that time, endosseous implants were placed in 25 of the sites, and healing abutments were placed; measurements were taken 4 to 6 months later with an electronic mobility testing device.Results: The percentage of residual biomaterial was 5.6% ± 8.9% for FIS (P <0.001), 20.2% ± 17.0% for BPBM (P <0.05), and 12.0% ± 16.4% for COR (P <0.001). The amount of residual biomaterial after 6 months showed a significant relationship with the insertion torque measurements during the first third of implant insertion (P <0.05) and with values of the electronic mobility testing device at the abutment connection (P = 0.05). Histologically, new bone apposition was seen on BPBM particles. FIS sites showed similar ingrowth of blood vessels and osteocytes as empty controls.Conclusion: All sites revealed good primary stability at implant insertion and proper implant rigidity at abutment placement, indicating that early implant osseointegration was not influenced by the application of bone biomaterials used in this study.

Authors: Repasi V. , Agostinelli A. , Nagy P. , Coiro M. , Hecker K. , Lamberti F. 
Published: June 2008

Abstract
The distribution of species of the Xiphinema americanumgroup in Hungary was studied by collecting 272 samples from 53 localities. Samples have been taken from soil in the rhizosphere of 70 plant species. In total, 12.86 % of the samples contained at least one species from the Xiphinema americanum-group. Three species were found: Xiphinema brevicollum, X. pachtaicum and X. simile. Xiphinema brevicollum occurred in 4.41 %, X. pachtaicum in 3.67 % and X. simile in 4.77 % of the samples. New data on plants associated with the reported species and developmental patterns for X. brevicollum and X. pachtaicum are also presented.
The effect of traditional management burning on lichen diversity
Authors: Davies G. Matt , Legg Colin J. 
Published: June 2008

AbstractQuestion: How does regular management burning of a northern, Calluna vulgaris‐dominated heathland affect the lichen diversity at the patch and landscape scale?Location: Mar Lodge Estate, Scottish Highlands, United Kingdom.Methods: 26 fire sites of different ages and 11 long‐term unburnt stands were surveyed to create a chronosequence of changing lichen diversity following burning. Data were analysed graphically, with a GLM and using a CCA.Results: Though the immediate effect of fire was to significantly reduce lichen diversity, it generally recovered within 20 years. There was a significant difference in the population dynamics between wet and dry moorland areas with terricolous lichens in the former site being replaced by pleurocarpous mosses. Older stands, unburnt for 25 years or more, generally had lower diversity than stands 10 to 15 years old. Changes in lichen diversity and community composition can be attributed to the development of Calluna stand structure following burning.Conclusions: Fire can be seen to play an important role in maintaining the diversity of lichens in heathland areas by providing a variety of stand‐structures and ages across the landscape that favours the development of greater beta‐diversity.

AbstractWith the aim to develop new potent and selective ligands of 5‐HT3‐type serotonin receptors and to acquire more information on their structure‐affinity relationships, new thieno[2,3‐d]pyrimidine derivatives 32–39 were synthesized and their binding to 5‐HT3 versus 5‐HT4 receptors was studied. Some of these new compounds exhibit good affinity for cortical 5‐HT3 receptors, but not for 5‐HT4 receptors. Among these derivatives, 6‐ethyl‐4‐(4‐methyl‐1‐piperazinyl)‐2‐(methylthio)thieno[2,3‐d]pyrimidine 32 is the most potent ligand (Ki = 67 nM); it behaves as a competitive antagonist of the 5‐HT3 receptor function in the guinea pig colon. Its binding interactions with 5‐HT3A receptors were analysed by using receptor modelling and comparative docking.
The nucleolus of the maternal gamete is essential for life
Authors: Lefèvre Brigitte 
Published: June 2008

AbstractThe mammalian oocyte is a round cell arrested at prophase I of meiosis. It is characterized by the presence of a large nucleus, called the germinal vesicle, in the middle of which is the nucleolus. Before it can be fertilized, the oocyte must resume meiosis, enter metaphase II and be ovulated. The nucleolus is dissolved during this process. However, the nucleoli of the male and female pronuclei in the zygote are both of maternal origin. A recent paper1 demonstrates that the maternal nucleolus, together with other nucleoplasmic elements, is essential for early embryonic development. These nucleolar and nucleoplasmic factors remain undetermined. BioEssays 30:613–616, 2008. © 2008 Wiley Periodicals, Inc.
MicroRNA mutant turns back the evolutionary clock for fly olfaction
Authors: Jones Walton D. 
Published: June 2008

AbstractIn a recent paper, Cayirlioglu et al. report that the disruption of a specific miRNA, miR‐279, which normally acts to inhibit the transcription factor Nerfin‐1, uncovers a population of hybrid CO2 neurons in the Drosophila maxillary palp.1 Normally, fruit fly CO2 neurons are found only in the antennae, while mosquito CO2 neurons are found only in the maxillary palps. The hybrid neurons in this miRNA mutant may, thus, recapitulate an evolutionary intermediate unseen since the divergence of these two dipteran lineages over 250 million years ago.
