Assessment of levels of calprotectin levels in cervicular fluid from implant sites with peri implant pathogenesis

Introduction: Peri-implant crevicular fluid (PICF) contains calprotectin, which are markers for inflammation and bone resorption, respectively. The aims of this study were to assessment of levels of calprotectinlevelsincervicular fluid from implant sites with peri implant pathogenesis.in PICF from implant sites with peri-implant diseases and to evaluate the usefulness of calprotectin diagnostic markers for peri-implant diseases. Methods: 90 patients with dental implants participated in this study. PICF samples were collected from peri-implant disease sites (n=50) and non-diseased (healthy) sites (n=40) after clinical indicators including probing depth (PD), bleeding on probing (BOP), gingival index (GI), and bone loss (BL) rate were investigated. Calprotectin amounts in PICF were measured using their respective ELISA kits and then compared between diseased and healthy samples. The relationship between PICF calprotectinand levels and clinical indicator levels was investigated. Results: Calprotectin levels in PICF were significantly higher from peri-implant disease sites than from healthy sites. Conclusions: Calprotectin levelsin PICF have potential as biomarkers for the diagnosis of peri-implant
Worldwide Coverage Mobile Systems for Supra-Smart Cities Communications: Featured Antennas and Design

Current terrestrial mobile communications networks can’t provide worldwide coverage. Satellite communications are expensive, and terminals are large and heavy. Worldwide mobile coverage requires the use of satellites providing an appropriate QoS, including polar regions. The analysis of the potential satellite constellations demonstrates that LEO one is the best solution. A new generation of low cost, small size, lightweight and global mobile coverage LEO satellites is emerging. The main limitation of the terminals is the antenna size factor, and innovative antennas must be developed to meet this goal. This paper investigates the technologies and techniques for designing and developing antennas aimed at LEO satellite communications in Smart Cities and beyond, which are especially beneficial for mobile communications in areas without 4G/5G coverage. The paper focuses on the terrestrial segment and future mobile devices, remarking the design constraints. In this scenario, the paper reviews the most relevant technologies and techniques used to design suitable antennas. The investigation analyses the state-of-the-art and most recent advances in the design of antennas operating in the Ku-band. The main contribution of the authors is a novel antenna design approach based on SIW technology. The antenna features are compared with other approaches, highlighting the benefits, advantages and drawbacks. As a conclusion, the proposed antenna demonstrates to be a good solution to meet the design constraints for such an application: light, low cost, small size factor.
Factors that influence community-based tourism (CBT) in developing and developed countries

Abstract Many community-based tourism (CBT) initiatives around the world have failed to deliver expected benefits because of unfavorable conditions involving a variety of entwined social, cultural, economic, and political factors. Because of different economic, legislative, and political conditions, factors that facilitate and inhibit CBT are believed to be different in developing and developed nations. A directed content analysis of CBT case studies in 48 developing countries and 37 developed countries show that some of these differences vary in being advantageous or disadvantageous for either developing or developed nations. Furthermore, many case studies do not address factors and themes essential for tourism development because of the lack of a clear CBT framework guiding their research and a lack of integration of external conditions in the analysis. In general, collective land and tourism initiative ownership can provide certain advantages to communities in developing countries when it gives them control over land, tourism and natural resources, independence in decision-making, participative management and wider distribution of benefits.
Effect of temperature on structural and optical properties of iron sulfide nanocrystals prepared from tris(N-methylbenzyldithiocarbamato) iron(III) complex

Abstract Tris(N-methylbenzyldithiocarbamato)iron(III) complex was used to prepare iron sulfide (FeS) nanocrystals, FeS1 at 120, FeS2 at 180 and FeS3 at 240 °C. P-XRD revealed that the nanocrystals FeS1 and FeS2 are in hexagonal pyrrhotite, Fe9S10, crystalline phase whereas FeS3 nanocrystal is in pyrrhotite-6C, Fe11S12, crystalline phase. TEM images showed nanocrystals with an average diameter of 5.42 and 25.07 nm for FeS1 and FeS2, respectively, while cluster of iron sulfide with an average particle size of 6.40 nm was obtained for FeS3. The optical band gaps obtained from the Tauc plots are 3.90, 3.90 and 3.96 eV for FeS1, FeS2 and FeS3 nanocrystals, respectively, which indicate blue shifts ascribed to quantum confinement.
Doxorubicin-Induced Cardiotoxicity: From Mechanisms to Development of Efficient Therapy

First isolated in the early 1960s, doxorubicin (DOX) is among the most effective antican - cer agents ever developed. DOX has been used mainly for the treatment of breast cancer, solid tumors in children, soft tissue sarcomas, and aggressive lymphomas. However, the use of DOX may have dose-dependent cardiotoxic effects that generate changes in myo cardial structure, which can develop into severe and irreversible cardiomyopathy. Here, we describe the incidence of DOX-induced cardiotoxicity (DIC); the progress made over the past four decades in understanding the molecular mechanisms of the pathogenesis of acute and chronic DIC; the current strategies for heart protection; and the major break throughs and challenges in basic and clinical research to the development of efficient targeted therapy for DIC. showed a decrease in ROS generation, preservation of cardiac function, and reduction of mor tality rate after acute and chronic DOX administration in the eNOS knock-out (eNOS − / − ) mice model, whereas cardiomyocyte-specific eNOS overexpression intensified the pathological response to DOX in the heart [ 28 ]. In all, these studies demonstrate the importance of eNOS signaling in DIC.
The Use and Significance of Early Bronze Age Stone Battle-axes and Axe-hammers from Northern Britain and the Isle of Man

The perforated stone battle-axes and axe-hammers of Early Bronze Age Britain have been used either to interpret the status of individuals they were buried with or have been overlooked; this is especially the case with axe-hammers. Previous understandings have assumed battle-axes were purely ceremonial, while the rougher axe-hammers were neither functional nor prestigious, being too large and too crude to be prestige items. Studies of the 20th century were focused on creating a typology and understanding the manufacture and petrological sources of the stone, concluding that haphazard exploitation of stone was used to create a variety of different shapes of both implements. This paper revisits the question of how these artefacts were used. It presents the results of the first large-scale application of use-wear analysis to British Early Bronze Age battle-axes and axe-hammers, from northern Britain and the Isle of Man. Combining the results of the wear analysis with experimental archaeology and contextual analysis, it is argued that these objects were functional tools, some of which saw prolonged use that might have spanned multiple users. The evidence shows that the few implements found in burial contexts were both functional and symbolic; their inclusion in burial contexts drawing upon relational links which developed through the itineraries of these objects. It is also apparent that use and treatment were similar across all types of battle-axe and axe-hammer, with some regional variation in the deposition of axe-hammers in south-west Scotland. It is concluded that battle-axes and axe-hammers had varied and multiple roles and significances and that it is possible to discover what each artefact was used for by deploying a use-wear analysis methodology.
The use of discourse markers in oral discourse in EFL classroom by pre-service EFL teachers

This article presents and discusses a computer-assisted case study of the use of discourse markers (further—‘DMs’) in oral discourse in English as a Foreign Language (EFL) by pre-service teachers in Norway. The aim of this case study is to explore the use of DMs by pre-service teachers (further referred to as ‘participants’) in EFL classroom by means of analysing the participants’ answers to the questionnaire that is designed to address the use of DMs in oral discourse in EFL after their school practice. The case study is informed by the view of DMs as “sequentially dependent elements that bracket units of talk” (Schiffrin, 1987: 31). The quantitative analysis of the participants’ questionnaires in statistical program SPSS version 18.0 (2009) indicates that the participants’ repertoire of DMs in their oral discourse in EFL classroom consists of such DMs as also, and, as, because, besides, but, especially, if, OK, or, so, and then. Additionally, the participants note that they do not use the following DMs during their teaching practice at school, e.g. indeed, moreover, and rather. These findings and their linguo-didactic implications will be further discussed in the article.
Myrtenal averts apoptotic evasion of cancer cells in 7,12-dimethylbenz(a)anthracene induced experimental oral carcinogenesis

Apoptotic avoidance is one of the foremost characteristic features of tumour cells. Apoptotic induction in cancer cells could thus help to identify new anticancer agents from the natural products. The present study has taken an effort to investigate the apoptotic efficacy of myrtenal, a monoterpene, in 7,12-dimethylbenz(a)anthracene (DMBA) induced oral carcinoma in male golden Syrian hamsters. The present study used the potent carcinogen, 7,12- dimethylbenz(a)anthracene, to develop oral tumours in the buccal pouches of the golden Syrian hamsters. Topical application of the above said carcinogen on the buccal mucosa (3 times a week for 14 weeks) resulted in well differentiated oral squamous cell carcinoma. The apoptotic potential of myrtenal was investigated using a spectrum of apoptotic markers, including pro-apoptotic and anti-apoptotic markers. Oral tumours developed in the buccal mucosa of hamsters showed higher expression of mutant p53 protein, Bcl-2 and lowered expression of Bax, Bad, Bid, caspase 3 and caspase 9. Myrtenal treatment at a dose of 230mg/kg bw orally to the hamsters treated with DMBA modulated the above said apoptotic markers towards tumour suppression or inhibition. The present findings thus suggests that the tumour preventive effect of myrtenal could partly be ascribed to its apoptotic induction potential during DMBA induced oral carcinogenesis.
“Evolution” of Embryogenesis: Complexity of the Early Developmental Stages in the Animal Kingdom

Multicellularity has gained the advantage over the unicellular world by expanding the number of increasingly more complex tissues that achieve advanced and specific functions. This same event gave rise to the most evolved group of organisms, namely mammals. Even though the complexity of multicellular organisms does not necessarily provide them with excellent adaptation modes performed by unicellular and prokaryotic organisms, this complexity per se stands as one of the greatest phenomena in biology. However, there is an inherent set of biochemical and physiological programs that all animals share and tend to execute in similar manners. Most of these processes are evolutionarily conserved and often arise several times with different phylogenetic origins; this implies their importance and universalism in the Animal kingdom. This review summarizes the most significant embryological mechanisms described in many model organisms of echinoderms, nematodes, insects, chordates, and mammals including humans. Although complex and diverse, most of the mechanisms share an outstanding number of similarities that lead researchers to find the answer as to how and in which way the mechanisms had succeeded to help develop complex life.
Antibiotic drug release behavior of poly (vinyl alcohol)/sodium alginate hydrogels

Poly (vinyl alcohol)/sodium alginate hydrogels were prepared by freeze‐thaw followed by calcium ion crosslinking. Chloramphenicol release behavior from the poly (vinyl alcohol)/sodium alginate hydrogels in mimic conditions of gastrointestinal tract was examined. The effects of composition, number of freeze‐thaw cycles and calcium ion concentration on drug release process were investigated. The results showed that the cumulative release amount of chloramphenicol from the hydrogels (crosslinked through 4 freeze‐thaw cycles and immersed in 2 % calcium chloride solution) decreased from 84.3 % to 72.3 % as sodium alginate content increased from 0 % to 75 %. For the hydrogels containing 50 % sodium alginate and immersed in 2 % calcium chloride solution after the freeze‐thaw cycles, cumulative release amount of chloramphenicol decreased from 83.5 % to 76.6 % as the freeze‐thaw cycles increased from 2 to 6. Cumulative release amount of chloramphenicol from the hydrogels containing 50 % sodium alginate and with 4 freeze‐thaw cycles decreased from 79.8 % to 75.6 % when concentration of calcium chloride solution increased from 1 % to 4 %.
Guardian high school student’s conception about mathematics as sensible

One of the characters that students should hold as the effect of learning mathematics is positive character about mathematics. It means students believe that mathematics is sensible. Students who view mathematics as sensible think that mathematics is interrelated concepts and mathematics is related to other concepts. Students’ conception may be different because basically human have different personalities. There is a relation between student conception about mathematics and their personality type. One of the personality type based on Keirsey Temperament Sorter is guardian. This study describes guardian high school student conceptions about mathematics as sensible. One female student whose personality type is Guardians is purposively selected as a research subject. The subject is assigned a mathematics real world problem and interviewed based on the problem solving task to measure her conception about mathematics as sensible. The interview guideline is developed based on SCOMAS framework. The result indicates that guardian subject shows the conception that mathematics is sensible. However, not all of the indicators can be verified. The subject plans a strategy and alternative strategy to solve the problem, explains the way to solve the problem and the reason of applying some concepts, and connects the solution to the real situation. The subject doesn’t show the activity of seeking connection among mathematics concepts.
Evaluation of appendicitis inflammatory response score in suspected cases of acute appendicitis

Background: Acute appendicitis is a common surgical disease with varied clinical presentation, diagnosis of which, can be at times a clinical challenge. In order to aid in the clinical diagnosis various scoring system have been designed one of which is the appendicitis inflammatory response score (AIR score).

It is recommended for workers to use MSB tools every time they work.
Hysteresis in a linear chain of magnetic nanoparticles

We perform kinetic Monte Carlo simulation to study the magnetic hysteresis in a one-dimensional chain of magnetic nanoparticles (MNPs). The hysteresis behavior is systematically analyzed as a function of several key parameters: anisotropy axis orientation, dipolar interaction strength λ, frequency ν of the applied magnetic field, and temperature T. The anisotropy axes of all the MNPs are assumed to make an angle α with the chain axis. In the absence of dipolar interaction and thermal fluctuations, the hysteresis follows the Stoner–Wohlfarth model as expected. Extremely weak hysteresis is observed with small values of dipolar interaction strength for ν = 10 5 Hz and T = 300 K. On the other hand, there is a significant hysteresis even for weakly interacting MNPs with ν = 10 9 Hz. The hysteresis properties are strongly dependent on these parameters. Due to an increase in the ferromagnetic coupling, the hysteresis loop area increases with λ. The coercive field H c and the amount of heat dissipated E H due to hysteresis decrease rapidly with α and T for small values of λ and ν = 10 5 Hz, while for large λ, they fall very slowly. When ν is very large ( = 10 9 Hz), E H and H c are found to have negligible dependence on T irrespective of λ. The results with a small value of frequency should be taken into account in the interpretation of the experiments and efficient usage of magnetic hyperthermia.
Conceptualizing eWOM, Brand Image, and Brand Attitude on Consumer’s Willingness to Pay in the Low-Cost Airline Industry in Thailand

The expansion usage of the Internet, especially social media, has extended customers options for gathering products and services information by including other customers' comments and opinions posted on the Internet. Customers are able to share their experience, perception, and advice by involving in electronic word-of-mouth (eWOM) on their social media and websites that facilitate reviewing of consumer’s experiences, which can be reached by their friends and other potential customers. This study reviews literature related to eWOM, brand attitude, brand image, brand loyalty, and their implication on the willingness to pay premium ticket price in the context of the low-cost airline industry in Thailand. Existing literature presented that eWOM, as well as, brand image have positive influences on customer’s repurchase intention. In addition, brand attitude and brand loyalty also influence customers’ intention to buy for a particular product. This leads to the motivation to formulate a conceptual framework to explore the relationships between the mentioned independent variables on the willingness to pay more on airline ticket price. This conceptual framework also suggests methodology and sample groups for further research investigation.
Empleo informal. Evolución teórica y criterios para su estimación derivados de la Organización Internacional del Trabajo (OIT)

Este articulo tiene el objetivo de contribuir al analisis teorico del empleo informal y a la definicion de criterios para su estimacion. Las discusiones sobre la informalidad del trabajo y las propuestas para su medicion en America Latina iniciadas en la decada de los setenta se han modificado y extendido conforme se acentuan la flexibilidad y la precariedad laboral. La Organizacion Internacional del Trabajo (OIT) ha estudiado el concepto hasta proporcionar nuevos elementos para su comprension y medicion tanto en paises desarrollados como en desarrollo. Aqui se analizan los primeros enfoques sobre el sector informal y la evolucion teorico-estadistica de la OIT para revelar dos rutas de medicion del empleo informal que incluyen al empleo asalariado como categoria esencial del mercado de trabajo. Concluye que el concepto puede ser operativo para analizar y estimar las condiciones de ocupacion en economias con distintos niveles de desarrollo.
Examining the dynamics of industry–university collaborations in Ghana

PurposeUniversity–industry (UI) collaborations are now a crucial issue as universities explore innovative means to secure industry funding for research and improve the employability content of existing curricula. This paper explores the dynamics of the antecedents of UI collaborations in management education. It further investigates the moderating variables (motivation, national policy and institutional factors) that are likely to influence the positive relationship between the antecedents of collaboration and the intention to collaborate.Design/methodology/approachA quantitative survey sent to 300 participants in academia and industry in Ghana achieved an 83% response rate. The data was analysed using bivariate and multivariate techniques.FindingsThe results revealed a positive relationship between knowledge sharing, trust, communication and motivation for UI collaborations. Motivation did not have a moderating effect on the positive relationship between any of the five independent variables and UI collaborations. Institutional factors were found to moderate the positive relationship between knowledge sharing and collaboration.Practical implicationsPolicy to encourage UI collaborations should build on reputational and intrinsic rather than purely financial motivations as academics are motivated by a complex mix of monetary and non-monetary factors.Originality/valueThis paper highlights the need for an intricate alignment of the interests of academia and practitioners to encourage UI collaboration efforts.
