    Background: The intake of green tea has been increased recently due to its medicinal values. The antibacterial and antioxidant properties of green tea were found to be beneficial in the treatment of gingival and periodontal diseases. The aim of this comparative study was to compare the efficacy of the mouthwash containing green tea and chlorhexidine in the management of dental plaque-induced gingivitis. Materials and Methods: Thirty patients who participated in the study were divided randomly into two groups, each group of 15 patients was prescribed with either chlorhexidine or green tea mouthwash. Turesky modification of Quigley-Hein plaque index, Löe and Silness gingival index, Ainamo and Bay bleeding index, tooth stain, and tongue stain (TS) were recorded at baseline, 15 days, and 1 month. The subjects were asked to report any discomfort or alteration in taste. Results: There was a significant decrease in plaque index, gingival index, and bleeding index in both the groups. However, green tea mouthwash resulted in a statistically significant decrease in bleeding index compared to chlorhexidine group. There was no significant difference in tooth stain and TS in both the groups. Conclusion: The green tea-containing mouthwash is equally effective in reducing the gingival inflammation and plaque to chlorhexidine. PMID:26681856

  2. Understanding the Significance of Mutations in Tumor Suppressor Genes Identified Using Next-Generation Sequencing: A Case Report

    Next-generation sequencing (NGS) of tumors has been heralded as a promising tool to identify ‘actionable’ abnormalities susceptible to therapies targeting these mutated genes. Inhibiting the oncoprotein expressed from a single dominant mutated gene (oncogene) forms the basis for the success of most of the targeted gene therapies approved in the last several years. The well over 20 FDA-approved kinase inhibitors for cancer treatment are examples [Janne et al.: Nat Rev Drug Discov 2009;8: 709–723]. These and other similar agents in development might prove effective therapies for tumors originating from tissues other than those for which these drugs are currently approved. Finding such mutations in tumors of patients through NGS is being aggressively pursued by patients and their oncologists. For identified mutated tumor suppressor genes (TSG) the challenge is really the opposite. Rather than inhibiting the action of an oncoprotein, targeting would involve restoring the activity of the wild-type (WT) TSG function [Knudson: Proc Natl Acad Sci USA 1971;249: 912–915]. Here, a case is reported that illustrates the implications of a mutated TSG (BRIP1) identified by NGS as potentially actionable. In such cases, measuring allelic mutation frequency potentially allows for the identification of tumors where the loss of heterozygosity of a TSG exists. Without substantial loss of expression of the WT TSG product, it would seem very unlikely that ‘replacing’ a WT TSG product that is not a lost product would be a useful therapy. PMID:27462233

    Bartonella quintana has been reported as the cause of trench fever, persistent endocarditis, bacteriaemia and has been isolated with an increasing incidence in clinical specimens from AIDS patients. One of the main pathogenic factors of gram-negative bacteria, including B. quintana, is the lipopolysaccharide (LPS). However, very little information is available on the features of Bartonella LPS. The aim of the present study was to extract, purify and characterise B. quintana LPS. The effect of the LPS under scrutiny was also evaluated on TNFa release by means of the "in vitro" human whole blood model of sepsis. The Oklahoma strain of B. quintana was grown on sheep blood agar, at 37 C, in a moist atmosphere containing 5% carbon dioxide. Cells were harvested and washed in sterile and apyrogenic saline solution and LPS extracted following the procedure of Westphal e Jann (1965), modified by Minnick (1994). The LPS of B. quintana showed the migration pattern of a deep rough chemotype, and the chromogenic limulus amoebocyte lysate test (LAL test) revealed strong reactivity at low concentrations (6.2 pg/ml). Samples of human whole blood stimulated by 1000 ng/ml of B. quintana LPS released 1707 378 pg/ml of TNFa.

    Patients undergoing orthodontic treatment with fixed appliances are at risk of developing carious white spot lesions and gingival inflammation because of the challenge of oral hygiene. The purpose of this study was to evaluate under home conditions the effectiveness of three different types of electric toothbrushes during active appliance therapy: Interplak (Bausch & Lomb, Berlin, Germany), Rota-dent (Rota-dent, Kusnacht, Switzerland), and Braun Oral-B Plaque Remover (Braun/Oral-B, Kronberg, Germany). A manual technique, which included normal toothbrush, interdental brush, and dental floss, served as reference. The study was structured as a single-blind "Latin square design" study. Thirty-eight orthodontic patients were randomly allocated to groups who, within the test period, alternately used the toothbrushes. Before getting a new toothbrush that was to be used for a period of 4 weeks, each patient received video and written instructions. For another 4 weeks, the patient returned to the usual oral hygiene procedures before receiving the next new toothbrush. Oral hygiene was evaluated at the start of a new test period and after 2 and 4 weeks. Clinical scores included a modified O'Leary Plaque Index and Ainamo Gingival Bleeding Index. Wilcoxon rank testing for aggregated surfaces revealed statistically significantly lower plaque scores for Rota-dent than for the manual technique (p < 0.01). For all other toothbrushes, no differences were found in comparison to the manual technique. For Plaque Indices of specific sites, statistical analysis revealed all electric toothbrushes to be equal to the manual technique. No differences in Gingival Bleeding Indices were found after 4 weeks with either toothbrush. Patients with poor oral hygiene who used Rota-dent and Braun Oral-B Plaque Remover OD5 had statistically significantly lower plaque scores compared with the manual technique (p < 0.01; p < 0.05); for patients with good oral hygiene, these differences were neutralized

  6. The Role of Multiple Shocks in the Production of GeV Gamma-ray Flaring in the Blazar 1156+295

    As part of work to identify jet conditions during GeV flaring detected by the Fermi-LAT, we have carried out radiative transfer modeling of a pair of centimeter-band, total and polarized flux outbursts in the FSRQ 1156+295 from the UMRAO data archive. The modeling incorporates propagating shocks and uses the observed spectral evolution between 14.5 and 4.8 GHz as constraints. The two outbursts are nearly identical in amplitude, spectrum and duration. However, the centimeter-band outburst peaking in 2010.75 is temporally associated with a series of GeV flares extending over nearly 300 days with peak photon flux exceeding 10^{-6} photons/cm^2/s, while the centimeter-band outburst which commenced in early August 2008 is temporally associated with a well-defined gamma-ray quiescent state. Our analysis reveals that the shocks in the parsec-scale jet during the two events have a similar sense (forward), orientation (transverse) and compression, but in the case of the orphan radio-band flare only 2 shocks were required to reproduce the light curves, while in the event with a paired gamma-ray flare, 4 shocks were required. VLBA imaging of the inner jet at 43 GHz identifies a single jet component during the orphan flare and complex structure in the later event. This suggests that differences in shock structure, and associated shock interactions, play a role in the production of gamma-ray flares.

    The capsular K5 polysaccharide, a representative of group II capsular antigens of Escherichia coli, has been cloned previously, and three gene regions responsible for polymerization and surface expression have been defined (I. S. Roberts, R. Mountford, R. Hodge, K. B. Jann, and G. J. Boulnois, J. Bacteriol. 170:1305-1310, 1988). In this report, we describe the immunoelectron microscopic analysis of recombinant bacteria expressing the K5 antigen and of mutants defective in either region 1 or region 3 gene functions, as well as the biochemical analysis of the K5 capsular polysaccharide. Whereas the K5 clone expressed the K5 polysaccharide as a well-developed capsule in about 25% of its population, no capsule was observed in whole mount preparations and ultrathin sections of the expression mutants. Immunogold labeling of sections from the region 3 mutant revealed the capsular K5 polysaccharide in the cytoplasm. With the region 1 mutant, the capsular polysaccharide appeared associated with the cell membrane, and, unlike the region 3 mutant polysaccharide, the capsular polysaccharide could be detected in the periplasm after plasmolysis of the bacteria. Polysaccharides were isolated from the homogenized mutants with cetyltrimethylammonium bromide. The polysaccharide from the region 1 mutant had the same size as that isolated from the capsule of the original K5 clone, and both polysaccharides were substituted with phosphatidic acid. The polysaccharide from the region 3 mutant was smaller and was not substituted with phosphatidic acid. These results prompt us to postulate that gene region 3 products are involved in the translocation of the capsular polysaccharide across the cytoplasmic membrane and that region 1 directs the transport of the lipid-substituted capsular polysaccharide through the periplasm and across the outer membrane.

    For the first time since its inaugural meeting in Lund in 1983, the triennial international conference on Atomic Spectroscopy and Oscillator Strengths for Astrophysical and Laboratory Plasmas (ASOS) returned to Lund, Sweden. Lund has been a home to atomic spectroscopy since the time of Janne Rydberg, and included the pioneering work in laboratory and solar spectroscopy of Bengt Edlén, who presented the initial ASOS talk in 1983. The ninth ASOS was hosted by the Lund Observatory and the Physics Department of Lund University during from 8 to 10 August 2007 and was attended by nearly 100 registrants. An encouraging sign for the field was the number of young researchers in attendance. This volume contains the submitted contributions from the poster presentations of the conference, and represents approximately forty percent of the presented posters. A complementary volume of Physica Scripta provides the written transactions of the ASOS9 invited presentations. With these two volumes the character of ASOS9 is more fully evident, and they serve as a review of the state of atomic spectroscopy for spectrum analysis and the determination of oscillator strengths and their applications. The goal of ASOS is to be a forum for atomic spectroscopy where both the providers and users of atomic data, which includes wavelengths, energy levels, lifetimes, oscillator strengths, and line shape parameters, can meet to discuss recent advances in experimental and theoretical techniques and their application to understanding the physical processes that are responsible for producing observed spectra. The applications mainly originate from the fields of astrophysics and plasma physics, the latter including fusion energy and lighting research. As a part of ASOS9 we were honored to celebrate the retirement of Professor Sveneric Johansson. At a special session on the spectroscopy of iron, which was conducted in his honor, he presented his insights into the Fe II term system and his most recent

The ninth ASOS was hosted by the Lund Observatory and Physics Department of Lund University, 7-10 August 2007, and was attended by 99 registrants. An encouraging sign for the field was the number of young researchers in attendance. This volume of Physica Scripta contains contributions from the invited presentations of the conference. For the first time, papers from the ASOS9 poster presentations have been made feely available online in a complementary volume of Journal of Physics: Conference Series. With these two volumes the character of ASOS9 is more evident, and together they serve as a review of the state of atomic spectroscopy for spectrum analysis and the determination of oscillator strengths and their applications. The goal of ASOS is to be a forum for atomic spectroscopy, where both the providers and the users of atomic data, which includes wavelengths, energy levels, lifetimes, oscillator strengths and line shape parameters, can meet to discuss recent advances in experimental and theoretical techniques and their application to understanding the physical processes that are responsible for producing observed spectra. The applications mainly originate from the fields of astrophysics and plasma physics, which includes fusion energy and lighting research. The oral presentations, all but one of which are presented in this volume, provided an extensive synopsis of techniques currently in use and those that are being planned. New to ASOS9 was the extent to which techniques such as cold, trapped atoms and molecules and frequency combs are

The difference lies mainly in the scaling, i.e. how prominently the different variables influence the C-band data at the different spatial (25 km versus 20 m) and temporal (daily versus 3-30 days repeat coverage) scales. Therefore, while the general properties of soil moisture retrievals schemes used for ASCAT and Sentinel-1 can be the same, the details of the algorithm and parameterization will be different. This presentation will review similarities and differences of soil moisture retrieval approaches used for ASCAT and Sentinel-1, with a focus on the change detection method developed by TU Wien.

In its turn, in its general setting the problem of strain and piezoelectric potential calculation requires the solution of a nonlinear system of partial differential equation. A large experience in solving these two parts of the problem separately, independently of each other, has been already accumulated in the distinct communities of the researchers. This BIRS workshop effectively combined expertise of these research communities, summarized the state-of-the-art for modeling LDSNs and key challenges facing these communities, and explored ways to address those challenges in interdisciplinary team settings. The workshop brought together researchers working on different aspects of the analysis and modeling of LDSNs which require a concerted efforts of teams of researchers with close interactions between applied and pure mathematicians, physicists (theoreticians and experimentalists), computational scientists, and engineers. These scientific and engineering communities were represented in Banff by the researchers from Japan, Canada, the USA, Russia, France, Denmark, Germany, and the UK (further details can be found at http://www.m2netlab.wlu.ca/ldsn-banff/). We had four main plenary talks of one hour duration that gave state-of-the-art overviews of the subject from perspectives of applied mathematics (Professor Russel Caflisch of the University of California at Los Angeles), physics (Professor Antti-Pekka Jauho of the Danish Technical University), and computational science and engineering communities (Professor Gerhard Klimeck of Purdue University), as well as from a point of view of experimentalists (Dr Gail Brown of the Materials Lab/Air Force Research Lab at Wright-Patterson AFB). These talks helped identify the areas where joint efforts needed to be directed to, and they set up the scene for further work during the workshop, including discussions at the workshop open problem sessions.

    information [7] and in Stockholm he had, again, very successful postdocs such as Ulf Leonhardt. Finally, in 2005, Stig Stenholm retired, although he is still active, writing papers, taking part in conferences and making research visits. We honoured his 70th birthday at the CEWQO2009 conference, and hope that the future provides us with further opportunities for such events. Looking at the obituary of Dirk ter Haar, I see that his style with students reminds me of Stig's approach. In my opinion, Stig expects independence and initiative from a student, giving perhaps a broad topic in which the student is expected to find his or her own way, whilst working perhaps with a postdoc. Juha Javanainen has talked about the 'sink or swim' style (not referring to Stig, though). There is a famous series of children's books about Moomin trolls by Tove Jansson (another Swedish-speaking Finn like Stig). In one of them, the Moomin find in early spring a small flower in a patch of land uncovered by snow, pushing its way up. One of them wants to cover it against frost during the night, but another says 'Don't, it'll fare better later if it has some difficulties at first'. At CEWQO2009 Stig gave the full list of his finished PhD students: Rainer Salomaa (1973), Temba Dlodlo (1980), Juha Javanainen (1980), Markus Lindberg (1985), Matti Kaivola (1985), Birger Ståhlberg (1985), Kalle-Antti Suominen (1992), Mackillo Kira (1995), Päivi Törmä (1996), Asta Paloviita (1997), Patrik Öhberg (1998), Martti Havukainen (1999), Erika Andersson (2000), Pawel Piwnicki (2001), Åsa Larson (2001), Markku Jääskeläinen (2003), and Jonas Larson (2005). One should also mention Erkki Kyrölä, who eventually graduated at Rochester and Olli Serimaa, who never graduated but published some important early-stage laser cooling work. As a final note I must mention a passion that Stig and I share, namely books. I have nearly 400 professional physics and mathematics books, but I am certain that the size of Stig

The conference site was the new ICT building at the University of Turku campus area and the Viking Line ferry boat. Turku is the central city of historical Finland established on the mouth of the river Aura in the 13th century. It is the birthplace of Finnish academic life, since the Academy of Turku was established there in 1640. In 2011, Turku will be one of the cultural capitals of Europe. The city has a strong maritime tradition and is shielded from the Baltic sea by a large and beautiful archipelago. The 17th Central European Workshop on Quantum Optics will be held in 2010 in St Andrews, UK. It will be chaired by Professors Ulf Leonhardt and Natalia Korolkova from the School of Physics and Astronomy, University of St Andrews. St Andrews is home to the first university of Scotland, the third-oldest in the English-speaking world, and is the home of golf. It remains a charming, eccentric seaside town that is sufficiently secluded - the ideal place for a stimulating and thought-provoking conference.
