A Case of Gingivobuccal Coplex Cancer of Anterior Maxilla in a 14 Year Old Child
No full textIntroduction: Squamous cell carcinoma (SCC) of the oral cavity ranks as the 12th most common cancer in the world and the 8th most frequent in males. SCC is extremely unusual in the pediatric population and researchers believe that the pathology of SCC in pediatric patients is a separate entity different from SCC in the adult population.Materials and Methods: A 14 year old girl patient with ill-defined swelling with 1.5 x 4cm ,ulcerated surface texture along with tiny bleeding points was came to department of Oral and Maxillofacial Surgery K.D.Dental College & Hospital Clinically the lesion appears to be a benign soft tissue tumor with provisional diagnosis of peripheral giant cell granuloma. Pre-surgical investigations which were carried out were found to be within normal range. Radiographic examination did not reveal any significant bone loss in relation to the maxillary right anterior teeth or bone. Results: SCC of gingiva by histopathological examination was confirmed and patient referred to nearby cancer institute for definitive treatment. Conclusion: Despite the fact that SCC has been frequently reported in old male patient, here, we reported a case of young female patient. Since the early detection of SCC is vital, presence of SCC in younger patients also needs to be considered by paediatrics
A literature review of pandemic novel coronavirus disease 2019 and potential drugs treatment
Get PDFBackground: Coronaviruses (CoVs) belong to a family that comes under the order “Nidovirales.” Nidovirales order includes the viruses that use a nested set of mRNAs for their replication. CoV disease 2019 (COVID)-19 is a βCoV-2, CoV of the same subgenus as severe acute respiratory syndrome (SARS) virus, but in a different clad. The constitution of the receptor-binding gene region is very like to that of the SARS-CoV, and the virus has been demonstrated to utilize the same receptor, the angiotensin-converting enzyme 2, for entrance into respiratory cells. There are presently no drugs or vaccinations that are known to be successful for SARS-CoV-2 management or preventing the spread as per various major health officials. Aim: This review describes various drug treatment options available against COVID-19. It focuses on the use virology of SARS-COV2, potential drugs that can be utilized to treat COVID-19 infection, their dosages, advantages, side effects, and indications. Conclusion: As there are no definitive treatment modes accessible to cure SARS-COV2 infection to this date, drug repurposing can provide effective tool to combat against COVID-19 until definitive drugs or vaccines discovered to treat SARS-CoV2 infection. Various antiviral, antiparasitic, and antimalarial drugs, antibodies, Vitamin C, Vitamin D, melatonin hormone, etc., are effective to reduce viral load of COVID-19. Clinical Significance: Drug repurposing and previous or recent clinical experiences with CoV infection provide an efficient weapon to COVID-19 infection. They are effective in not only reducing viral load of COVID-19 infection but also minimize the symptoms related to SARS
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
