Novel material for root-end applications for bio-allied sciences

Treating a patient with tooth pain is a multi-factorial process with many factors playing their role to warrant the success of the treatment procedure. One such important factor is to secure the root apex which is important for ensuring good prognosis in endodontics. Also in challenging situations like sealing a fractured root, resorbed apex, or an incompletely formed apex, the need of an intact root apex is much anticipated. Over the years, an array of novel products has been produced for root-end applications to achieve such a favorable condition. The objective of this review is to list and summarize such root-end materials. However, their merits, and claims of superiority over MTA, have to be ascertained via sustained research.

Macroalgae Community Structure at Semak Daun Island, Kepulauan Seribu, Indonesia

Semak Daun Island was part of the Kepulauan Seribu which was a marine tourism destination such as snorkeling and diving site. The existence of these activities had been affecting the condition of the biota community that lives in these waters including macroalgae. The condition of macroalgae communities can be observed by abundance, diversity, uniformity and dominance analysis that occur in these communities that are known as the community structure. The purpose of this study was to determine the structure of macroalgae communities (abundance, diversity, uniformity and dominance) in Semak Daun Island. This research results was found 3 divisions, 10 orders, 13 families, 15 genera and 20 species of macroalgae. The abundance of macroalgae ranges from 235 - 782 individuals/100m2, classified as low abundance. Diversity ranges from 0.96 to 1.83, classified as low diversity. Uniformity ranges from 0.4 to 0.71, including the moderate uniformity and Dominance ranges from 0.22 to 0.57 belong to the low to moderate category, with the most dominant species being Galaxaura rugosa. Physics-chemical parameters of water in general are included in the normal range to support macroalgae life. Based on this, the condition of the macroalgae community structure on Semak Daun Island which is in a less favorable condition is likely due to the existence of snorkeling and diving activities by tourists. Keywords: community structure, macroalgae, Semak Daun Island

THE IMPORTANCE OF DEVELOPING HIGH-QUALITY HUMAN RESOURCES IN THE CENTRAL HIGHLANDS OF VIETNAM NOWADAYS

Vietnam in general and the Central Highlands in particular are in the process of accelerating industrialization, modernization and international integration in the context of the scientific and technological revolution that has strongly developed in the whole world. This is a favorable condition and opportunity for the Central Highlands to take advantage of the achievements of science and technology to accelerate industrialization and modernization by taking a shortcut to gain a head start. To take advantage of opportunities and overcome challenges created by globalization and international integration, it is necessary to have strong internal resources. But the first important resource is human resources, especially high-quality human resources. In this article, the author focuses on analyzing the importance of developing high-quality human resources in the Central Highlands today. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0740/a.php" alt="Hit counter" /></p>

Immunoexpression of metalloproteinases 9 (MMP-9) and 2 (MMP-2) and their inhibitors (TIMP-1 and TIMP-2) in normal and neoplastic canine mammary tissue

The aim of this study was to perform the immunostaining of MMP-9 and MMP-2 and its inhibitors, TIMP-1 and TIMP-2, on normal and neoplastic canine mammary tissue in order to evaluate the behavior of these proteins in extracellular matrix (ECM) remodeling in different neoplastic mammary types. Thus, 48 samples of canine mammary tissue were analyzed, 14 of which complex carcinomas, 13 tubulopapillary carcinomas, six single adenomas and 15 normal mammary tissue. There were differences in MMP-9, TIMP-1 and TIMP-2 according to mammary histomorphology, and MMP-9 presented increased immunoexpression in epithelial and stromal cells in tubulopapillary and complex carcinomas. TIMP-1 exhibited reduced immunostaining in the stromal cells of the complex carcinomas and TIMP-2 enhanced immunostaining in the epithelial cells of tubulopapillary carcinomas. There was a positive correlation between MMP-9 and TIMP-1 in epithelial and stromal cells regarding immunostaining intensity and number of labeled cells in the normal breast. There was a positive correlation between MMP-9 and TIMP-2 in the epithelial cells of tubulopapillary carcinomas. It is concluded that balanced activity between MMP-9, MMP-2, TIMP-1 and TIMP-2 maintains normal canine mammary tissue homeostasis while increased immunoexpression of MMP-9 and TIMP-2 and reduced TIMP- 1 in carcinomas suggest a favorable condition for tumor evolution.

Pleasant Ambient Scents: A Meta-Analysis of Customer Responses and Situational Contingencies

To prevail in the fierce competition of in-store experiences, some firms have focused on providing pleasant ambient scents. However, equivocal results on scent effects make generalizations and managerial guidance uncertain. While efforts to consolidate research findings have been conducted, a comprehensive quantitative integration is notably lacking. In this meta-analysis, the authors integrate 671 available effects from ambient scent experiments and show that exposure to pleasant ambient scents on average produces a substantial increase in the level of customer responses (3%–15%). The effects of ambient scent depend on situational contingencies and are, for example, positively related to congruency, unidimensional aroma structure, ascribed familiarity of a scent, service exchange, proportion of female participants in the sample, and imagined (vs. fictitious) offering. Thus, the authors estimate expenditures would increase by 3% and 23% for an average and a most favorable condition, respectively. The authors also examine effect patterns, identifying, for example, ambient scent as more cognitive than affective and nonlinear effects of perceived concentration. Using the insights, they develop a research agenda and provide clear strategic guidance to leverage ambient scent effects.

Influence of E-Marketing Strategy on Customer Satisfaction

Over the past two decades, several attempts were made to provide best practices for e-service quality measurement and e-marketing strategy. It is always necessary to measure the performance quality of web services using different means such as E-SERVQUAL model. The customer satisfaction gets enhanced after measuring the E-service quality in a service-based company. The proposed study uses E-SERVQUAL model for measuring the service quality of an E-commerce Company. The survey questionnaire method is used to collect responses from customers of the company via email and newsletters. The results indicate that factors: efficiency, reliability, assurance and security in the e-service system are in favorable condition and factor: responsibility is not in the favorable condition that affects the customer satisfaction level of the company. Managerial implications are proposed with the help of theoretical study of e-marketing strategy 2P+2C+3S to enhance customer satisfaction of the company

An approach to the clinical manifestation of Rupavriddhi Rupahani Rupantara in Avarana

Ayurveda believes in different pathology which sets in different Srotas to produce different diseases. Whenever a favorable condition and situation arise, diseases will manifest. Nanatmaja Vikara, Anubandha, Gatavata and Avarana are different pathologies explained in Ayurveda. Avarana is one of the most difficult concept to understand teach and incorporate in clinical practice. It is either least observed, diagnosed or goes unidentified due to lack of skill. To understand and analyze the Avarana, Meticulous knowledge of basic concept of Ayurveda is essential. It is assumed that symptoms complex in Avarana leads to misunderstanding, wrong diagnosis and sometimes end with complications. The symptoms produced in Avarana are based on the principles of Rupahani (Karmakshaya), Rupavriddi (Karmavriddhi) and Rupantara (Anya Karma). The present article is an attempt made to have a critical clinical study of role of Avarana in the manifestation of Rupavriddhi, Rupahani, Rupantara.

Water-gas-shift reaction on reduced gold-substituted Ce1−xO2(111) surfaces: the role of Au charge

Au+ falls into a relatively favorable condition for catalyzing the WGS reaction due to a compromise between attractive interaction and Coulomb repulsion between the Au and the transferred proton.
