Management of distally luxated left maxillary central incisor and intruded left maxillary canine by intentional replantation and extrusion followed by labial and lingual splinting and endodontic treatment: A case report

Field: Dentistry (Health Sciences)

This case report presents a case of a patient with lateral luxation of the maxillary left central incisor and intrusive luxation of maxillary left canine. Patient had trauma due to bicycle fall 4 days ago. Clinical examination of maxilla revealed lateral luxation of the maxillary left central incisor, avulsion of maxillary left lateral incisor and intrusive luxation of maxillary left canine having grade III mobility. The maxillary right central incisor and maxillary right lateral incisor presented with grade I tooth mobility. The patient sustained lacerations and mucosal damage in maxillary left anterior region. Surgical extrusion and intentional replantation followed by splinting for 4 weeks were performed to treat these injuries. The patient was asymptomatic after one year of follow-up with no external or internal root resorption.
Intensive care admission and hospital mortality in the elderly after non-cardiac surgery in Spain: secondary analysis of EuSOS study

Field: Health Professions (Health Sciences)

Assessment of nurses' compliance and understanding of the confusion assessment method for the intensive care unit as a delirium screening tool in the London teaching hospitalAuthors: Krupa M.1, Crerar-Gilbert A.21St George's University Hospitals NHS Foundation Trust, Cardiothoracic Intensive Care Unit, London, United Kingdom, 2St George's University Hospitals NHS Foundation Trust, Dept of Anaesthesiology & Intensive Care, London, United KingdomBackground and Goal of Study: The Confusion Assessment Method for the ICU (CAMICU) is a validated tool to diagnose delirium in the intensive care. It yields three ratings: positive, negative and unable to assess (UTA). The quality improvement project1 in the cardiothoracic unit (CTICU) 2 years ago resulted in high (80%) compliance in performing CAMICU. This study was undertaken to assess if CAMICU compliance was maintained and that scoring was accurate.Materials and Method: Retrospective data was collected from the CTICU charts for all patients during one week. The CAMICU rating and the sedation score (RASS) at the time of the test were recorded. Data was collected and analysed in a Microsoft Excel. Ethics permission was not required.Results and Discussion: Between 31/10/16 - 06/11/16, 52 patients data was analysed from which it was calculated that 128 CAMICU tests should have been performed. 108 (84%) CAMICU tests were completed. The CAMICU was rated:u2022tpositive in 5 tests (4.7%);u2022tnegative in 58 (53.7%);u2022t45 tests (41.6%) were rated UTA.18/45 (40%) of CAMICU UTA assessments were considered inappropriate as they were associated with RASS scores -3 or above (CAMICU should be done in this group2). However, many of the patients who should have received CAMICU scores (but who did not) were on the lower end of the responsiveness spectrum (-2 or -3) as measured using RASS (14/18 patients). No explanation is given for failure to assess patients with RASS scores -1 or above.Conclusion: Following the CTICU improvement project compliance with performing the CAMICU remained high. However, this study identified that quality of testing is suboptimal. Excessive use of the UTA rating shows possible lack of understanding of how to apply the CAMICU to patients with low level of consciousness. Further education and training is required. References: 1.

Risk factors of consumer switching behaviour for cross-border e-commerce mobile platform

Field: Business, Management and Accounting (Social Sciences)

The cross-border e-commerce mobile market was an application of the mobile internet era; therefore, the cross-border e-commerce mobile platform also has a 'transfer cost law'. This study explored the risk factors of consumer switching behaviour for cross-border e-commerce mobile applications. We combined perceived risk, transfer cost and user loyalty VSL framework theory to construct a new cross-border e-commerce mobile market user transfer intention framework, and analysed the relationship between user loyalty, transfer costs and transfer intentions in the cross-border e-commerce mobile market, and provided advice to companies in the cross-border e-commerce mobile market. 1614 valid questionnaires were collected from e-survey. The analytical results indicated the higher the perceived value and the lower the perceived risk, the higher the user satisfaction. User satisfaction will directly improve user loyalty, and high transfer costs with high user loyalty will directly weaken the user's transfer intention. However, further research shows that learning costs were not directly related to user loyalty and transfer intention, and the complexity of a cross-border e-commerce platform did not directly lead to user transfer.

Database Marketing: OLD WINE IN A NEW BOTTLE!!!

Field: Business, Management and Accounting (Social Sciences)

The database marketing field is growing day by day. Lots of people have their inboxes filled on a daily basis with email messages advertising items that they might want to buy. The list is produced by companies who conduct studies and is then sold to other companies who market yet more businesses products. The current availability of on-line direct marketing databases provides numerous opportunities for marketing professionals to improve their marketing strategies and tactics. Database marketing is as old as the World Wide Web. It is no longer merely a case of shopping for a database of telephone numbers and cold calling them in the hopes of creating a sale. Data base marketing, now a days is being used as the foundation for developing a market segmentation approach to identify new prospects and thus providing a mechanism for organizing the company's marketing activities. Lifetime value analysis, a concept that plays a major role in CRM, is used to group prospects into 'good', 'better,' and 'best' categories and thus provide an understanding of the likely responsiveness of these segments. Emphasis is a new marketing program to appeal to these prospective customers. Many people also see a disadvantage in the database approach of marketing by believing it is too intrusive. Database marketing involves large amounts of information about customers that is used as a basis for future advertising. However, proponents claim there is nothing wrong with using compiled information about customers, and deny any intrusion. This paper, which will be a descriptive one, author is highlighting the recent trends of database marketing. how it can be more effective, what are the bottlenecks, in doing the same. Further the paper will also argue, about the origin and usage of these so called new and efficient efforts.
Effect of Metal Film Electrode Layer on Electrical Properties of Na2O-PbO-Nb2O5-SiO2 Glass-ceramic Capacitors

Field: Materials Science (Physical Sciences)

The electrical performance of the stacked glass-ceramic capacitors depends largely on the inner elec- trode structure and the interface quality. In this work, several metal films, such as Pt, Au, Cu and Ag, were depos- ited by DC magnetron sputtering serving as inner electrode layers between the dielectric layer and the silver paste electrode of glass-ceramic capacitors. The effect of the deposited metal films on the electrical properties of Na2O-PbO-Nb2O5-SiO2 glass-ceramic capacitors was investigated. Compared with the single paste electrode struc- ture, Pt and Au metal films could effectively improve the electrical performance of the capacitors, corresponding to an increase of equivalent capacitance by 25% and a decrease of leakage current by an order of magnitude. SEM observations indicate that the Pt, Au and Cu metal films would help the formation of a dense electrode/dielectric interface and inhibit the diffusion of silver, whereas a porous interface and intense silver diffusion are often found in the single screen-printed paste electrode and the deposited Ag metal electrode. The above results reveal that Pt and Au metal films as inner electrodes could make the interface microstructure inhibit the silver diffusion and enhance the overall performance of the glass-ceramic based capacitors.
Spatial control of hairy protein expression during embryogenesis

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

ABSTRACT We have used a polyclonal antiserum specific for the Drosophila segmentation gene, hairy (h), to analyse its expression during embryogenesis. The pattern of wildtype expression resembles that of h transcription, being expressed in stripes at the blastoderm stage, h is also expressed later in the stomodæum, proctodæum, tracheal pits and mesoderm. We demonstrate that h protein stripes show consistent phase relationships to those of the even-skipped (eve) pair-rule gene. We examine h protein patterns in embryos mutant for other segmentation genes, including h itself. We show that lack of h activity appears not to affect h striping, arguing that h expression is not under autoregulatory control. We also show that h activity is not needed for tracheal invagination. Mutations that are rearranged upstream of the h gene cause the loss of specific stripes, indicating that the h promoter includes activating elements that respond to specific spatial cues. Our observations suggest that pairrule striping may be under redundant control, and we discuss possible implications for hierarchical models of pair-rule gene action.
514 Factors associated to return to work after sickness absence due to mental disorders among brazilian workers

Field: Health Professions (Health Sciences)

Introduction

Mental disorders are the third leading cause for grant sickness social security benefit in Brazil. Those workers have longer time to return to work (RTW) comparing to other disabilities. This study aims to analyse factors associated to RTW after an episode of sickness absence due to mental disorders (MD).

Methods

A longitudinal study was conducted in the city of São Paulo, Brazil, from 2014–2016. Included 204 workers requiring sickness social security benefit due to MD. At baseline, participants fill questionnaires about sociodemographic, health risk behaviours, work characteristics, health conditions and social security history. They were followed for 365 days after the first day of sickness absence. Survival analysis (Kaplan-Meier curve and Cox regression) were performed to identify factors influencing the first RTW.

Result

The group was composed mostly by women (71.1%), people aged under 40 (67.6%) education equal or higher 12 years (80.4%) and diagnosed as depressed (52.9%). Many worked in customer service jobs (44.1%), reported effort-reward imbalance at work (57.4%) and high overcommitment (74.2%). The average time for return to work was approximately six months among the 63.0% who tried to resume their work activities. Factors associated to return to work within one year after sick leave were: aged between 30–39 years (HR 1.76; 95% CI: 1.08 to 2.79), 12 or more years of education (HR 1.87; 95% CI: 1.10 to 3.17), low alcohol intake (HR 2.65; 95% CI: 1.75 to 4.02) and low level of anxiety symptoms at baseline (HR 0.17; 95% CI: 0.04 to 0.74) – when analysis were adjusted by sex and job title.

Discussion

Sociodemographic characteristics, risk health behaviours and medical conditions at baseline were associated to RTW after sick leave due to MD. Further studies, with larger sample, are needed to improve estimates and discussion focused in interventions to early RTW in public and private sectors. Acknowledgments: CNPq grant no442051/2014–0.
Winners' and Losers' Attributions for Success and Failure in a Series of Athletic Events

Field: Psychology (Social Sciences)

Boys who participated in a series of athletic events as part of their activities at an overnight camp evaluated the importance of possible causes for success and failure in these events. These reasons included the four traditional attributions of ability, effort, luck and task difficulty, and other attributions suggested in previous person-perception studies of the causes of outcomes in achievement-related tasks. The results indicated the following: (a) two of the traditional attributions (luck and difficulty) were perceived as having little importance, (b) success was attributed to internal factors whereas failure was attributed to external factors, (c) the differences between the winners and losers provided little evidence for the presence of a self-serving bias in their evaluations of the items, and (d) the differences between actors and observers were not entirely consistent with the hypothesis that actors attribute outcomes to situational factors and observers attribute the same outcomes to dispositional factors. These results are discussed in light of possible confounds in the experimental design and previous attribution research in sport.
Boron Neutron Capture Therapy‐Derived Extracellular Vesicles via DNA Accumulation Boost Antitumor Dendritic Cell Vaccine Efficacy

Field: Medicine (Health Sciences)

Abstract Radiated tumor cell‐derived extracellular vesicles (RT‐EVs) encapsulate abundant DNA fragments from irradiated tumor cells, in addition to acting as integrators of multiple tumor antigens. Accumulating evidence indicates these DNA fragments from damaged cells are involved in downstream immune responses, but most of them are degraded in cells before incorporation into derived RT‐EVs, thus the low abundance of DNA fragments limits immune responses of RT‐EVs. Here, this study found that different radiations affected fates of DNA fragments in RT‐EVs. Boron neutron capture therapy (BNCT) induced DNA accumulation in RT‐EVs (BEVs) by causing more DNA breaks and DNA oxidation resisting nuclease degradation. This is attributed to the high‐linear energy transfer (LET) properties of alpha particles from the neutron capture reaction of 10 B. When being internalized by dendritic cells (DCs), BEVs activated the DNA sensing pathway, resulting in functional enhancements including antigen presentation, migration capacity, and cytokine secretion. After vaccination of the BEVs‐educated DCs (BEV@BMDCs), the effector T cells significantly expanded and infiltrated into tumors, suggesting robust anti‐tumor immune activation. BEV@BMDCs not only effectively inhibited the primary tumor growth and metastasis formation but also elicited long‐term immune memory. In conclusion, a successful DC vaccine is provided as a promising candidate for tumor vaccine.

Behavioral Deficits in Wistar Rats Secondary To Altered Androgen Levels After Treatment With Chicken Feed And Raw Soybean

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Chicken meat is the most favorite consumable commodity current days. The eminent demand for the chicken meat is satisfied through the poultry farms operational day and night feeding the chicken feed as a chief basis for the untimely growth and weight growth of the chickens. The aim of the present study was to investigate the consequences of the commercially available chicken feed and raw soy bean on mood alteration in rats. Seventy five female albino wistar rats were used in the experiment. Animals were randomly allocated to three groups (n=25), control rats fed on standard rodent chow, chicken feed treated rats and raw soybean treated rats for a period of 6 weeks. Serum androgens levels were estimated before and after the treatment. After 6 weeks behavioral alterations like lateral attacks, biting and muricidal behavior was monitored in rats. Components of chicken feed were analyzed through Pakistan council of scientific and industrial research (PCSIR) laboratories. The present study showed that the behavioral deficits and serum androgen levels of the feed treated group rose significantly as compared to control group and spinach treated group. It was as a result, concluded that the chicken feed treated rats showed increased serum androgen levels with increase in lateral attacks, biting and muricidal behavior. The finding maybe suggested that the potential alterations in mood and behavior are due to chicken feed additives of animal by products that may lead to increase androgen levels in chickens. This finding may be of relevance to the dietary inclination of population more towards chicken products which may lead to alteration in androgen levels and behavioral changes.
Tree crown condition in Virginia before and after Hurricane Isabel (September 2003)

Field: Environmental Science (Physical Sciences)

per hour (59 to 111 km per hour) and gusts up to 91 miles per hour (146 km per hour), the hurricane caused widespread damage throughout Virginia and is a plausible explanation for adverse changes observed in tree crown condition since the hurricane. On average, trees measured before and after the hurricane showed a signifi cant increase in foliage transparency. Increases in foliage transparency were greatest for loblolly pine, sweetgum, and the Coastal Plain region of the State. A signifi cant correlation between tree size and increase in foliage transparency was not observed. This study highlighted the potential importance of foliage transparency as an indicator of tree damage from severe storms.
Measurement of aerodynamic forces acting on a rotating sphere by a magnetic suspension and balance system

Field: Engineering (Physical Sciences)

We used a Magnetic Suspension and Balance System (MSBS) in order to make accurate measurements of the Magnus force acting on a rotating sphere. The MSBS levitates the model by controlling the magnetic forces using electromagnets. Since the model is levitated by the MSBS, there is no support interference. We succeeded in measuring the Magnus force on the rotating sphere without the use of a physical support. It was measured that the Magnus force coefficient increases with increasing the spin parameter.
Evidence of the firm size effect in Singapore, conclusive or inconclusive?

Field: Economics, Econometrics and Finance (Social Sciences)

The "firm-size" effect is a well-documented anomaly in the finance literature. This paper attempts to establish whether a "firm-size" effect exists in the Stock Exchange of Singapore. Data for our research was extracted from the Financial Database of Nanyang Technological University and the local newspaper, The Straits Times. Samples of companies were collected according to the size of their market capitalization. The excess returns of each portfolio were computed and compared to that of the market excess returns for a period of five years, 1989 - 1993, on a daily basis. Based on our findings, it seemed that the excess return from each sample size was not significantly different from any other under the period of study. In conclusion, the "firm-size" phenomenon does not seem to be in existence in the local stock market.
On the Performance of Fixed-Income Exchange-Traded Funds

Field: Economics, Econometrics and Finance (Social Sciences)

The authors evaluate the performance of fixed-income exchange-traded funds (ETFs). They find that Treasury ETFs are indeed able to track their benchmarks but that investmentgrade corporate bond ETFs underperform their benchmarks and high-yield corporate bond ETFs severely underperform their benchmarks. They provide evidence that the transaction costs of the underlying bonds are a key determinant of an ETF’s underperformance. The authors conclude that indices consisting of bonds that are more costly to trade are more difficult to track.
