The Relationship between Periodontal Disease and Predisposing Factors

Periodontitis is an inflammatory lesion mediated by hostbacterial interactions which results in a non-resolving inflammation that leads to local connective tissue attachment loss from the tooth surface, loss of alveolar bone and ultimately tooth loss Indeed, periodontal disease is the leading cause of tooth loss in the western world and developing countries. The aims of thisstudy was to estimate the relationships between periodontal disease and predisposing factors. One hundred eighty samples (paper point inserted into periodontal pocket) were examined inthe present study . Patients were of both sexes(140 males and 40 females). Their ages ranged from 16-69 years old. Clinical measurements of periodontal parameters used included dentalplaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment loss . The results showed that periodontal disease was the most common in age group 20-29years old and only a case reported with periodontal disease in 65 years old patients. According to sex distribution of patients, periodontal disease was mostly found in males than females. Theperiodontitis was more common in non-educated,treated ,smoking patients they living in rural area than educated,non treated ,nonsmoking patients . they living in urban area.The most common anaerobic periodontal bacteria isolated from patients were peptostreptococcus prevotii which represented 15(8.3%) isolates, while prevotella intermedia, prevotella melani, prevotella disiens, Bifidobacterium sp. , Fusibacterium mortiferum peptostreptococcus tetradius ,and Wolinella sp. represented only 1 (0.5%) of anaerobic isolates . Also another anaerobic subgingival bacteria isolated from inflamed sites in patients were fusibacterium varium,nvellionella sp. , campylobacter gracilis, capnocytophaga sp. , peptostreptococcus magnus, peptostreptococcus micros, peptostreptococcus niger,peptostreptococcus anaerobius, staphylococcus saccharolyticus, streptococcus consellatus, and gemella morbillorum.
Feasibility of controlling 2019-nCoV outbreaks by isolation of cases and contacts

Background: To assess the viability of isolation and contact tracing to control onwards transmission from imported cases of 2019-nCoV. Methods: We developed a stochastic transmission model, parameterised to the 2019-nCoV outbreak. We used the model to quantify the potential effectiveness of contact tracing and isolation of cases at controlling a 2019 nCoV-like pathogen. We considered scenarios that varied in: the number of initial cases; the basic reproduction number R0; the delay from symptom onset to isolation; the probability contacts were traced; the proportion of transmission that occurred before symptom onset, and the proportion of subclinical infections. We assumed isolation prevented all further transmission in the model. Outbreaks were deemed controlled if transmission ended within 12 weeks or before 5000 cases in total. We measured the success of controlling outbreaks using isolation and contact tracing, and quantified the weekly maximum number of cases traced to measure feasibility of public health effort. Findings: While simulated outbreaks starting with only 5 initial cases, R0 of 1.5 and little transmission before symptom onset could be controlled even with low contact tracing probability, the prospects of controlling an outbreak dramatically dropped with the number of initial cases, with higher R0, and with more transmission before symptom onset. Across different initial numbers of cases, the majority of scenarios with an R0 of 1.5 were controllable with under 50% of contacts successfully traced. For R0 of 2.5 and 3.5, more than 70% and 90% of contacts respectively had to be traced to control the majority of outbreaks. The delay between symptom onset and isolation played the largest role in determining whether an outbreak was controllable for lower values of R0. For higher values of R0 and a large initial number of cases, contact tracing and isolation was only potentially feasible when less than 1% of transmission occurred before symptom onset. Interpretation: We found that in most scenarios contact tracing and case isolation alone is unlikely to control a new outbreak of 2019-nCov within three months. The probability of control decreases with longer delays from symptom onset to isolation, fewer cases ascertained by contact tracing, and increasing transmission before symptoms. This model can be modified to reflect updated transmission characteristics and more specific definitions of outbreak control to assess the potential success of local response efforts.
Checking Our Blind Spots: The Most Common Mistakes Made by Social Marketers

Background: The work of social marketers and the environment in which they work is complex, which inevitably results in mistakes being made and sometimes, the failure of a social marketing program. Unfortunately, social marketers do not often report their own mistakes. Even when failures or mistakes are reported, it is usually for the purpose of one study, as opposed to a wider understanding of mistakes made by social marketers in the field. This is a significant gap in the development of social marketing practice since understanding the nature of the most common mistakes made by social marketers could assist them in assessing their own shortcomings and potentially lead to more effective programs. Focus: This article is related to research and evaluation of the social marketing field. Research Question: What are the perceptions of social marketing experts regarding the most common mistakes made by social marketers? Importance to the Field: A greater understanding of the common mistakes made by social marketers will allow practitioners to assess their own shortcomings, improve program outcomes, and raise the status of the social marketing field. Methods: This research is qualitative and exploratory, with a constructivist, grounded theory methodology. In-depth interviews with 17 social marketing experts were conducted. Experts were purposefully chosen based on a set of criteria including the number of years of experience they had in the field. Results: The interviews revealed nine mistake categories: inadequate research, poor strategy development, ad hoc approaches to programs, mismanagement of stakeholders, poorly designed program objectives, weak evaluation and monitoring, poor execution of pilots, inadequate segmentation and targeting, and poor documentation. Additionally, the interviews revealed two other emergent, crosscutting themes that affect the mistakes being made: external influences that the social marketer may not have direct control over and the social marketer’s own preconceptions that they bring to the program. Recommendations for Research or Practice: Future research may explore (1) the extent to which external influences lead to social marketing program success or failure, particularly in comparison to mistakes made by social marketers and (2) perspectives from the social marketing community as to the most common mistakes made by social marketers. Social marketers may consider being more reflexive in their work, including reporting their own mistakes and failed programs, as well as challenging the biases they may bring to the work that they do. Limitations: The sample size is small and therefore not generalizable to all social marketing experts or the social marketing community. Also, there are many parts of the world in which social marketers practice, but which are not represented by the social marketing experts. Additionally, the “mistakes” listed are based on opinion as opposed to direct observation, which may make them more susceptible to bias.
Chapter 11 Reworking of older (1.8 Ga) continental crust by Mesoproterozoic (1.5–1.4 Ga) orogeny, Blekinge–Bornholm orogen, southeastern Sweden

Abstract The Blekinge–Bornholm orogen in southeastern Sweden consists of calc-alkaline to alkali–calcic intrusive rocks, rhyolites and dacites (1.8 Ga) that were structurally reworked under amphibolite facies conditions, affected by migmatization at mid-crustal levels at c. 1.44 Ga and intruded at c. 1.47–1.43 Ga by ferroan alkali–calcic plutons. This Mesoproterozoic orogen is bordered westwards by the Sveconorwegian orogen and northwards, along the boundary with well-preserved 1.8 Ga magmatic rocks in the Svecokarelian orogen, by a stitching c. 1.45 Ga pluton and steeply dipping ductile zones with a south-side-up, dip-slip shear component. A variably developed gneissic fabric (S1) dips gently to moderately northwards and is affected by asymmetrical F2 folds with a southerly vergence. Ductile high-strain zones with top-to-the south shear sense are suggested to correspond at depth to anomalously reflective zones along seismic profile BABEL line A. Open folding of the gneissosity around gently, north-plunging fold axes (F3) completed the ductile deformational evolution. Uncertainty remains about the timing of the amphibolite facies ductile fabric and the D2 folding, which is either late-stage Svecokarelian (c. 1.77–1.75 Ga) or Hallandian (c. 1.47–1.43 Ga). Non-collisional, accretionary orogenic systems are suggested to have operated during both time periods, radical reorganization of the subduction trend accompanying the Mesoproterozoic event.
Employee Turnover and Firm Performance: Large-Sample Archival Evidence

Employee turnover is a significant cost for businesses and a key human capital metric, but firms do not disclose this measure. We examine whether turnover is informative about future firm performance using a large panel of turnover data extracted from employees’ online profiles. We find that turnover is negatively associated with future financial performance (one-quarter ahead return on assets and sales growth). The negative association between turnover and future performance is stronger for small firms, for young firms, for firms with low labor intensity, when the local labor market is tight, and when the firm is trying to replace departing employees. The negative association disappears when turnover is very low, suggesting that a certain amount of turnover can be beneficial. Consistent with the concern that turnover increases operational uncertainty, we find a positive association between turnover and the uncertainty of future financial performance. Finally, we find a significant association between turnover and future stock returns, suggesting that investors do not fully incorporate turnover information. Our findings answer the call from the Securities and Exchange Commission to determine the importance of turnover disclosure. This paper was accepted by Brian Bushee, accounting.
Nutritional and Cellular Preconditioning in Ischemia-reperfusion Injury : Nutritionele en cellulaire preconditionering tegen ischemie-reperfusie schade

We investigated the impact of donor type on transcriptional changes that occur after organ retrieval and cold storage in kidneys and livers from living donors, DCD and DBD donors. Further studies describe the use of nutritional preconditioning and infusion of mesenchymal stem cells as possible treatments to ameliorate IRI. Finally, a mouse model with reduced expression of Fibulin-4 was used to study the local and systemic effects of renal IRI in short- and long-term.
Pre-burial taphonomic imprints on drilling intensity: a case study from the recent molluscs of Chandipur, India

ABSTRACT Palaeoecological studies of drilling intensity (DI), drawing ecological and evolutionary inferences, generally assume that drilled and undrilled specimens are equally preserved in the fossil record, because of the fact that the presence of drillholes does not affect preservation potential during sediment compaction. However, another facet that has not been studied conclusively is the taphonomic imprint on DI in a pre-burial scenario. If drillholes add weakness to a shell’s mechanical strength, drilled valves may preferentially be broken during post-mortem transportation, before its’ burial within sediment. In the present study, we test this hypothesis with a dataset involving DI and taphonomic status of two bivalve, Donax scortum and Mactra luzonica and two gastropod, Natica tigrina and Turricula javana species from Chandipur, India. Taphonomic status of each specimen is determined by relative preservation of its’ morphological characters. In case of both bivalves and gastropods, DI is found to be highest among the best preserved specimen and, thereafter, declines with increasing taphonomic degradation. When shell size is included in analyses, DI still shows an inverse relation with taphonomic alteration. This observed inverse relationship between drilling intensity and taphonomic imprint suggest that drilled shells may be vulnerable to breakage by pre-burial taphonomic processes.
Using Latent Profile Analysis for a Unique Perspective of a University Transfer Student Cohort

Transfer students differ from traditional first-year students on a number of variables that are typically related to retention and academic success at four-year institutions. While data-driven policies and programming represent a powerful method for meeting the needs of students, applying theories developed on traditional first-year students in order to understand transfer student performance may not reveal the unique needs in the transfer subpopulation. Latent profile analysis (LPA) offers a method for understanding performance in a diverse population while still honoring the characteristics of the individuals through person-centered analysis. In the current study, LPA was used to classify a diverse cohort of transfer students (n=417) into subclasses based on similar variable distributions and response patterns. Implications for practice according to the composition of class are discussed.
Using the Sakai Learning Management System to change the way Distance Education nursing students learn: are we getting it right?

ABSTRACT The popularity of LMSs tools and the different levels of interaction they offer have influenced learning. Interest in the use of technology among nursing students has risen and the need to find out how nursing students use Learning Management Systems to learn has become more critical now in developing countries and universities. Whilst LMSs initial focus had been on the administration of learning, there is the recent interest in how these LMS tools effectually result in learning and student satisfaction. The aim of the study was to explore whether students using LMSs such as Sakai to learn differently as they interact with their course content, their instructors and peers. Collaborative and communicative tools such as Wikis, Blogs and charts were not used intensively. The study found that students were not interacting effectively with their tutors. The lack of social presence has led to the use WhatsApp and Telegram by student groups as opportunities to enhance social presence. The findings suggest that effective use of Sakai CLE collaborative and communication tools can enhance interaction between students and content, instructors and students and among students and their overall learning.
Large‐Scale Geographical Variations and Climatic Controls on Crown Architecture Traits

Crown architecture is a critical component for a tree to interact with the ambient environment and to compete with neighbors. However, little is known regarding how climate variability may shape crown architecture traits across large geographical extents and whether crown architecture traits have coordinated variations with trunk and leaf traits to climate gradients. Here we used Quercus mongolica trees as an example, used the cutting‐edge terrestrial laser scanning technique to accurately characterize their crown architecture traits, and explored their variabilities along with environmental variability across large climate gradients in northern China. Our results showed that there are significant spatial variations in trunk, crown, and leaf traits even for the same genetic group across large environmental gradients. Tree height and leaf size had tight covariations with precipitation (|R|> 0.8, p < 0.01). We also observed coordinated variations among crown architecture traits related to canopy shape (e.g., primary branch insertion angle, chord length ratio), trunk traits (e.g., tree height), leaf traits (e.g., specific leaf area), and climate variability, highlighting there are likely fundamental evolutionary strategies regulating these covariations. With a projected drier and hotter climate scenario in this region, our results further suggest trees are expected to transit from a “tree shape” to a “shrub shape,” with large ecological and ecophysiological impacts on this region.
Evaluating the Topology Coverage of BGP monitors

: BGP monitors are currently the main data resource of AS-level topology measurement, and the integrity of measurement result is limited to the location of such BGP monitors. However, there is currently no work to conduct a comprehensive study of the range of measurement results for a single BGP monitor. In this paper, we take the first step to describe the observed topology of each BGP monitor. To that end, we first investigate the construction and theoretical up-limit of the measured topology of a BGP monitor based on the valley-free model, then we evaluate the individual parts of the measured topology by comparing such theoretical results with the actually observed data. We find that: 1) for more than 90% of the monitors, the actually observed peer-peer links merely takes a small part of all theoretical visible links; 2) increasing the BGP monitors in the same AS may improve the measurement result, but with limited improvement; and 3) deploying multiple BGP monitors in different ASs can significantly improve the measurement results, but non-local BGP monitors can hardly replace the local AS BGP monitors. We also propose a metric for monitor selection optimization, and prove its effectiveness with experiment evaluation.
Cloning and characterization of Osmotin (OsmSt) alleles from potato cultivar ‘Kufri Chipsona 1’

The present study was focussed to clone and sequence characterise alleles of osmotin from cDNA of Solanum tuberosum L. cultivar ‘Kufri Chipsona 1’. The genes vary in sizes as well as were found to have eleven point mutations throughout the coding sequence. One deletion of 7 bp was also found in smaller form of the gene having molecular weight of 19.91 KDa. Osmotin gene is known to impart resistance/tolerance to various fungal diseases in addition to its role as an osmoprotectant, thus, cloned osmotin alleles from important processing grade potato cultivar could become potential candidates for molecular breeding of potato.
A frequency reconfigurable MIMO antenna with agile feedline for cognitive radio applications

A novel frequency agile multiple‐input‐multiple‐output (MIMO) patch antenna based on a reconfigurable feedline is proposed. The proposed antenna structure has two hexagonal‐shaped patch antenna elements. A defected ground structure having hexagonal shape is included in the ground plane to make the design compact and improve isolation among antenna elements. Further compactness is achieved using reactive loading. Frequency reconfigurability is realized by employing varactor diodes in the microstrip feedline. The proposed antenna achieves a frequency reconfigurable band with wide tuning range from 1.42 to 2.27 GHz with good gain and efficiency. Furthermore, an envelope correlation coefficient value of less than 0.2 and minimum isolation of 12 dB was achieved, displaying good MIMO performance. The presented antenna has a planar, low profile design with compact size of 100 × 50 mm2. Thus, frequency agility, wide range tuning, compactness, and planar structure of the proposed antenna design make it suitable for modern wireless handheld devices particularly in cognitive radio applications.
Employability Study of the Business Administration Graduates of Catholic Educational Institution

The employability of university graduates is a concern in higher education as labor markets change more and more rapidly. This study assessed the employment status of Business Administration (BA) graduates for the past five years and the skills and competencies acquired in the University from what competencies desired in the industry. The study used descriptive research design and there were 875 BA graduates-respondents. Results of the survey showed that majority of the graduates are employed on a permanent status and were able to get employed for an average of four months after graduation. It also showed that majority works in an industry that is directly aligned to their course or expertise and the learned skills/competencies are valuable and suitable in their jobs. Furthermore, it revealed that communication skills, human skills and decision making skills are the soft skills/competencies that they learned in the University and are useful in their present jobs. Meanwhile, among the Marketing graduates, advertising skills, marketing plan preparation and service/product presentation skills are the top three learned hard skills in the University while among the Finance and Financial Management graduates, their top three are financial report preparation, cash management and technical analysis.
Comparative study of antibiofilm, cytotoxic activity and chemical composition of Algerian propolis

Antimicrobial agents are one of the strategies for inhibition of biofilm formation. But, most antimicrobials are not often effective in controlling of biofilm formation. Therefore, finding of new materials that have biofilm inhibitory effects is so important. In this regard, we aimed to determine the antibiofilm and cytotoxic effect of five Algerian propolis extracts obtained by extraction in solvents of varying polarity. Propolis extracts were tested for their ability to inhibit biofilm formation and to reduce preformed biofilm of eight bacterial strains including reference strains of Staphylococcus aureus (S. aureus ATCC29213 and S. aureus ATCC33862), three methicillin-resistant S. aureus (M10-1, M18-3, and M20-1), Enterococcus faecalis ATCC19433, Micrococcus luteus NRRL-B1013, and Yersinia enterocolitica RSKK1501. Cytotoxic activities of propolis extracts were determined using MTT test. Chemical investigation was performed using ultra-performance liquid chromatography with electrospray ionization coupled to tandem mass spectrometry (UPLC-ESI-MS/MS). All tested extracts exhibited the highest eradicating capability for S. aureus reference strains and methicillin-resistant strains, especially MRSA18-3 and MRSA20-1.The reduction of biofilm formation was found to be significantly affected by the used solvent for maceration, the tested bacterial strains, and the origin of tested propolis. In addition, biofilm reduction of Algerian propolis seemed to be dose-dependent. Moreover, all extracts showed high cytotoxic activity in colon adenocarcinoma cells. In addition, twenty-six phenolic compounds were detected. Difference between the amounts of detected compounds was found to be significant. Caffeic and ferulic acids were the main compounds in the tested extracts. These results suggest that those compounds might be responsible for the observed antibiofilm and cytotoxic activities of propolis extracts.
