Subgingival Microbial Profile And Production Of Proinflammatory Cytokines In Chronic Periodontitis
Authors: Dosseva-Panova Velichka T. , Popova Christina L. , Panov Vladimir E. 
Published: November 2014

ABSTRACT
This review examines literature data concerning the bacterial findings in chronic periodontitis depending on pocket depth, and presents the latest published information on the presence of proinflammatory factors in periodontal environment. It has been found that chronic periodontitis affects as much as 80% of the middle-aged population; by comparison, the prevalence of aggressive periodontitis reaches up to 1-1.5%. It is accepted that this social disease is multifactorial in etiology, but the evidence in the literature suggests that the levels of specifi c Gram-negative organisms in subgingival plaque biofilm play a major role in the initiation and progression of the disease. Of the many bacterial species inhabiting the periodontal environment, three types - Porphyromonas gingivalis (PG), Treponema denticola (TD), Tannerella forsythia (TF) - are strongly associated with the initiation and progression of periodontitis. Microbiological studies suggest that Porphyromonas gingivalis should be considered a major etiologic agent. Currently, Porphyromonas gingivalis is strongly associated with the pathogenesis of chronic periodontitis. On the other hand, the presence of Aggregatibacter actinomycetemcomitans in patients with chronic periodontitis may be related to the severity of the disease and thus modify the therapeutic plan. The increased amount of periodontal pathogens in the subgingival area can activate a cascade of defense mechanisms of the body associated with the production of factors causing infl ammation and destruction, which suggests a correlation between the bacterial findings and the body response implemented by enhancing the local cytokine expression. Studies in the literature show that the presence of certain micro-organisms in the periodontal environment is associated to increased levels of proinflammatory cytokines in the gingival fluid and gingival tissue. These levels have been associated with destructive tissues response. There is little evidence in the literature on the correlation of the levels of periodontal pathogens of sites with different pocket depth with periodontal disease activity defined by the degree of the proinflammatory cytokine expression such as tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6 ).

ABSTRACT
INTRODUCTION: YKL-40 is a glycoprotein believed potentially to be a marker of various pathological processes. High levels of YKL-40 have been found in cancer and chronic infl ammatory diseases. The function of the glycoprotein is not completely known yet. A possible involvement in angiogenesis and tumor aggressiveness is supposed. Lysosome-associated membrane glycoproteins (LAMP) 1 and 2 are highly conserved proteins with still undefi ned biological functions. There is evidence that they are implicated in autophagy, angiogenesis and tissue remodeling. AIM: The aim of the present study was to investigate the potential relationship between the tissue expression of YKL-40, LAMP-1 and LAMP-2 in glial tumors. MATERIAL AND METHODS: LAMPs and YKL-40 expression was determined by immunohistochemistry in 36 glial tumors. A morphometric analysis of the intensity of tissue expression was performed with the Quick-photo Micro 2.3. system. Area (μm), perimeter (μm), and expression level (%) of the three glycoproteins were calculated. RESULTS: LAMPs were found on cell membranes of glial and endothelial cells, while YKL-40 was detected in the cytoplasm of these cells. Intensive immunohistochemical reaction was present in tumor cells. LAMP-2 showed a more intensive staining compared to LAMP-1. CONCLUSION: We present the fi rst comparative study of YKL-40 and LAMPs in astroglial tumors. The relationship between the expression of the three glycoconjugates indicates a possible participation in the processes of angiogenesis and tissue remodeling during tumor development

Authors: Dzhambov Angel M. , Dimitrova Donka D. , Dimitrakova Elena D. 
Published: November 2014

ABSTRACT
BACKGROUND: Many women are exposed daily to high levels of occupational and residential noise, so the effect of noise exposure on pregnancy should be considered because noise affects both the fetus and the mother herself. However, there is a controversy in the literature regarding the adverse effects of occupational and residential noise on pregnant women and their fetuses. AIM: The aim of this study was to conduct systematic review of previously analyzed studies, to add additional information omitted in previous reviews and to perform meta-analyses on the effects of noise exposure on pregnancy, birth outcomes and fetal development. MATERIAL AND METHODS: Previous reviews and meta-analyses on the topic were consulted. Additionally, a systematic search in MEDLINE, EMBASE and Internet was carried out. Twenty nine studies were included in the meta-analyses. Quality effects meta-analytical model was applied. RESULTS: Women exposed to high noise levels (in most of the studies ≥ 80 dB) during pregnancy are at a significantly higher risk for having small-for-gestational-age newborn (RR = 1.19, 95% CI: 1.03, 1.38), gestational hypertension (RR = 1.27, 95% CI: 1.03, 1.58) and infant with congenital malformations (RR = 1.47, 95% CI: 1.21, 1.79). The effect was not significant for preeclampsia, perinatal death, spontaneous abortion and preterm birth. CONCLUSION: The results are consistent with previous findings regarding a higher risk for small-for-gestational-age. They also highlight the significance of residential and occupational noise exposure for developing gestational hypertension and especially congenital malformations.

Published: November 2014

ABSTRACTFertility of hybrid tea roses is often reduced due to their interspesific origin but also to intensive inbreeding. New genotypes used as pollen donors represent an economic risk for a breeding program, as their influence on seed production is unknown. In this study 9 garden rose genotypes were selected from a company database as high fertile or low fertile male parents, according to the number of seeds per hybridization. Pollen morphology and in vitro germination of the selected genotypes were characterized. Pollen was either small (mean diameter = 30 urn), shrunken, and irregular (abnormal), or large (mean diameter = 30 urn), elliptical and crossed by furrows (normal). High correlations were found between the number of seeds produced per hybridization and the pollen diameter (r = 0.94) or the percentage of normal pollen (r = 0.96). In order to evaluate the predictive power of the models, we conducted regression analyses and performed a validation experiment on genotypes not present in the database and without background information on fertility. Pollen diameter and percentage of normal pollen were characterized and fitted in the regression models for seed set predictions. Validation with an independent dataset gave a good prediction for 83.3% of the data. This indicates that using either the mean pollen diameter or the percentage of normal pollen resulted in effective fertility prediction. Moreover cluster analysis of the data classified all the cultivars into various groups with varying fertility. This tool could enhance the genetic variability in crossings between hybrid tea roses, thus creating possibilities for less economically risky exploitation of new tetraploid genotypes as male parents.
Effects of Water Stress on Germination of Yarrow Populations (Achillea Spp.) From Different Bioclimatic Zones in Iran

Published: November 2014

ABSTRACT
The effects of water potential on germination were studied in 18 wild populations of three yarrow species (Achillea tenuifolia, A. vermicularis and A. filipendulina) from different bioclimatic zones in Iran. Water potential between 0 and -0.6 MPa were obtained using polyethylene glycol 6000 (PEG-6000) solutions. The study of water stress on germination showed that, regardless of the species and the populations, the lowering of the water potential reduced the capacity for germination and early seeding growth. These results indicated a strong genetic potential for drought tolerance during germination within each species. These differences in germination ability of wild populations of each species might be attributed to intraspecific variations resulting from the effects of natural selection and genetic pool background.
La place du genre dans les revendications mémorielles gays et lesbiennes
Authors: Schlagdenhauffen Régis 
Published: November 2014

La définition du « genre du nous », appliquée aux revendications de reconnaissance des victimes homosexuelles du nazisme, met en lumière des tensions qui traversent les collectifs militants gays et lesbiens. À travers l’analyse de deux projets commémoratifs (Berlin et Amsterdam), l’auteur montre qu’elle est révélatrice de deux types de registres argumentatifs antinomiques. L’un, dirigé vers le passé, exclut les femmes de la commémoration (parce qu’elles n’étaient pas légalement persécutées) ; l’autre, orienté vers l’avenir, les inclut selon un principe universaliste de lutte contre l’homophobie.

Objective. This review synthesizes the published literature on using mass media campaigns to reduce youth tobacco use, with particular focus on effects within population subgroups and the relative effectiveness of campaign characteristics. Data Source. A search of PubMed and PsycINFO conducted in March of 2014 yielded 397 studies with 34 suitable for inclusion. Study Inclusion and Exclusion Criteria. Included were quantitative studies that evaluate an antitobacco media campaign intended to influence youth cognitions or behavior or explore the relative effectiveness of campaign characteristics among youth. Data Extraction. An automated search and assessment of suitability for inclusion was done. Data Synthesis. Study outcomes were compared and synthesized. Results. Antitobacco media campaigns can be effective across racial/ethnic populations, although the size of the campaign effect may differ by race/ethnicity. Evidence is insufficient to determine whether campaign outcomes differ by socioeconomic status (SES) and population density. Youth are more likely to recall and think about advertising that includes personal testimonials; a surprising narrative; and intense images, sound, and editing. Evidence in support of using a health consequences message theme is mixed; an industry manipulation theme may be effective in combination with a health consequences message. Research is insufficient to determine whether advertising with a secondhand smoke or social norms theme influences youth tobacco use. Conclusion. Our recommendation is to develop antitobacco campaigns designed to reach all at-risk youth, which can be effective across racial/ethnic populations. Research priorities include assessing campaign influence among lower SES and rural youth, disentangling the effects of message characteristics, and assessing the degree to which this body of evidence may have changed as a result of changes in youth culture and communication technology.

Purpose. To assess tobacco screening and counseling in student health clinics, including facilitators, barriers, and associations with campus- and state-level variables. Design. We conducted a mixed-methods study with an online survey and qualitative interviews. Setting. Study setting was student health clinics on college campuses. Subjects. Subjects included 71 clinic directors or designees from 10 Southeastern states (quantitative survey) and 8 directors or designees from 4 Southeastern states (qualitative interviews). Measures. Quantitative measures included demographics, screening and counseling practices, clinic-level supports for such practices, perceptions of tobacco on campus, institution size, public/private status, state tobacco farming revenue, and state tobacco control funding. Qualitative measures included barriers and facilitators of tobacco screening and counseling practices. Analysis. Logistic and linear regression models assessed correlates of screening and counseling. Qualitative data were analyzed using multistage interpretive thematic analysis. Results. A total of 55% of online survey respondents reported that their clinics screen for tobacco at every visit, whereas 80% reported their clinics offer counseling and pharmacotherapy. Barriers included lack of the following: time with patients, relevance to chief complaint, student self-identification as a tobacco user, access to pharmacotherapy, and interest in quitting among smokers. In multivariable models, more efforts to reduce tobacco use, student enrollment, and state-level cash receipts for tobacco were positively associated with clinic-level supports. Conclusion. This study highlights missed opportunities for screening. Although reports of counseling were higher, providers identified many barriers.

Purpose. To examine U.S. adult knowledge of the sugar content of sports drinks and whether this knowledge and other characteristics are associated with their sports drink consumption. Design. Nonexperimental. Setting. Nationally representative 2011 Summer ConsumerStyles survey data. Subjects. 3929 U.S. adults. Measures. The outcome variable was sports drink consumption in the past 7 days. The main exposure variable was knowledge about sports drinks containing sugar. The covariates were sociodemographic characteristics, physical activity, and weight status. Analysis. Multivariable logistic regression analysis was used to estimate adjusted odds ratios (ORs) for adults consuming sports drinks ≥1 times/wk after controlling for other characteristics. Results. Approximately 22% of adults reported consuming sports drinks ≥1 times/wk. Most adults (71%) agreed that sports drinks contain sugar; however, this agreement was not significantly associated with adults' sports drink consumption. The odds of drinking sports drinks ≥1 times/wk were significantly higher among younger adults aged 18 to 64 years (OR range: 5.46–2.71), males (OR = 2.09), high-school graduates (OR = 1.52), and highly active adults (OR = 2.09). Conclusion. There were disparities in sports drink consumption by sociodemographic characteristics and physical activity level; however, knowledge of sports drinks' sugar content was not associated with consumption. Understanding why some population groups are higher consumers may assist in the development of education, providing those groups with a better understanding of sports drinks' nutritional value and health consequences of excessive sugar consumption in any form.

Purpose. To determine when women receive pregnancy-related preventive health messages and to examine differences in receipt timing by maternal characteristics. Design. The cross-sectional secondary analyses used data from the Pregnancy Risk Assessment Monitoring System (PRAMS). Setting. The study used PRAMS responses from Maryland, Michigan, New Jersey, Ohio. Subjects. Study participants were women with a recent live birth. Measures. Health messages included mental health, safe medications, smoking, alcohol, and illegal drugs. The timing of message receipt was categorized as early (preconceptionally and prenatally) or late (prenatally only/never). Analysis. Weighted χ2 tests and multivariable logistic regression were used for analysis. Results. Among n = 3446, women with unintended pregnancies received all messages, except safe medications, significantly more early vs. late compared with women intending pregnancies (all p < .01). In multivariable analyses, there were no significant associations between timing of receipt and pregnancy intention, parity, preconception insurance status, or adequacy of prenatal care for any of the health messages. Hispanic women had increased odds of receiving the messages early compared with non-Hispanic white women, as did high school graduates vs. women with more education and women with lower household incomes vs. women with higher incomes. Conclusions. Women who may be perceived to be at higher risk of adverse pregnancy outcomes and/or engaging in high-risk behavior (minorities, lower education, lower income) appear to be getting messages early more often than do other women; messages are not reaching all women equally.

Purpose. This study examined municipal officials' participation in built environment policy initiatives focused on land use design, transportation, and parks and recreation. Design. Web-based cross-sectional survey. Setting. Eighty-three municipalities with 50,000 or more residents in eight states. Subjects. Four hundred fifty-three elected and appointed municipal officials. Measures. Outcomes included self-reported participation in land use design, transportation, and parks and recreation policy to increase physical activity. Independent variables included respondent position; perceptions of importance, barriers, and beliefs regarding physical activity and community design and layout; and physical activity partnership participation. Analysis. Multivariable logistic regression models. Results. Compared to other positions, public health officials had lower participation in land use design (78.3% vs. 29.0%), transportation (78.1% vs. 42.1%), and parks and recreation (67.1% vs. 26.3%) policy. Perceived limited staff was negatively associated with participation in each policy initiative. Perceptions of the extent to which physical activity was considered in community design and physical activity partnership participation were positively associated with participation in each. Perceived lack of collaboration was associated with less land use design and transportation policy participation, and awareness that community design affects physical activity was associated with more participation. Perceived lack of political will was associated with less parks and recreation policy participation. Conclusion. Public health officials are underrepresented in built environment policy initiatives. Improving collaborations may improve municipal officials' policy participation.

Authors: Piché Geneviève , Fitzpatrick Caroline , Pagani Linda S. 
Published: November 2014

Purpose. Health promotion in youth is likely to benefit from enhancing academic achievement and physical activity. The present study examines how kindergarten childhood self-regulation skills and behaviors predict involvement in both structured and unstructured physical and nonphysical extracurricular activities in the fourth grade. As a second objective this study also investigated how kindergarten childhood participation in extracurricular activities predicts classroom engagement, reflective of self-regulation, by the fourth grade. Design. Secondary analyses were conducted using prospective-longitudinal data. Setting. The Quebec Longitudinal Study of Child Development, Quebec, Canada. Subjects. Participants were randomly selected at birth from a stratified sample of 2694 born in Québec, Canada, between 1997 and 1998. Participants were included if they had complete data on teacher ratings of child self-regulation as measured by classroom engagement and parent ratings of sports participation (n = 935). Measures. Teachers reported self-regulation skills in children through a measure of classroom engagement. Parents provided reports of child participation extracurricular activities. Analysis. Ordinary least-squares regressions were conducted. Results. A higher-frequency kindergarten involvement with structured physical activities was associated with fourth-grade classroom engagement (β = .061, 95% confidence interval [CI]: .017, .104). Better kindergarten classroom engagement predicted more frequent participation in fourth-grade structured physical activities (β = .799, 95% CI: .405, 1.192) and team sports (β = .408, 95% CI: .207, .608). Conclusion. Results suggest mutual relations between physical activity and self-regulation from kindergarten to grade four. This suggests strong learning skills indicative of self-regulation and opportunities to participate in supervised physical activities or sports teams may help children develop healthy dispositions and behaviors in emerging adolescence.

Purpose. To examine predictors for persistent overweight/obesity, deteriorated weight status, and improved weight status among students who participated in a school-based obesity prevention intervention from fall 2009 to spring 2011. Design. Longitudinal assessment of a school-based cohort was conducted to determine the characteristics of students who remained overweight/obese, improved their weight status, or showed deteriorated weight status during an 18-month period. Setting. Eleven schools in southern Indiana, northwestern Kentucky, and southeastern Illinois. Subjects. N = 5309 students in 4th through 12th grade. Measures. Weight, height, and self-reported physical activity and nutrition behaviors of students were measured at baseline and 6, 12, and 18 months. Analysis. SAS 9.3 was employed to examine predictors for the three different weight categories using logistic regression. Results. Low socioeconomic status (SES) (adjusted odds ratio [AOR] = 1.56 and p < .001, AOR = 1.35 and p = .0069, respectively) and higher soda intake (AOR = 1.07 and p = .0016, AOR = 1.08 and p = .0278, respectively) increased the odds of belonging to persistent overweight/obesity (30.6%) and deteriorated weight status (6.9%), compared to the persistent nonoverweight status group. Conclusion. While SES is an important determinant of weight category change, students' screen time and soda consumption may be important factors. Schools and families may be able to successfully focus on these modifiable risk factors, decreasing the burden of childhood obesity.
