Protein toxicity in Kotri Paint industry workers exposed to Phthalic Anyhydride and Trimellitic Anyhydride
Get PDFBackground: Protein plays a significant role in the regulation of metabolism for normal functioning in human body. SITE area, Kotri paint industry workers are at high risk of hypersensitivity, sensitization of the respiratory tract (including asthma), skin diseases and allergy. Reactive Low molecular weight organic acid anhydrides (OAAs) like trimelitic anhydride (TMA) and phthalic anhydride (PA) are extensively used in local paint industries of SITE AREA, Kotri, Sindh – Pakistan. These both anhydrides may easily bind with high molecular weight proteins by forming complex (adducts) leading to metabolic disorders among the exposed workers.Methods: There is no study to differentiate protein status of workers compared with normal healthy group as compare in the past. In this regard, the total protein was determined in intravenous blood samples obtained from the exposed workers to TMA and PA with control group clinically by Microlab300 (Kit Method System).Result: There is a significant decrease of protein level in paint industry workers as compared with healthy subjects, which never had exposed to TMA and PA.Conclusion: These both allergenic organic acid anhydrides like TMA and PA may be associated for changing protein function status after forming complex (adduct) by long exposure at work. SITE Area, Kotri Paint workers may at high risk of asthma, exposed to TMA and PA
An overview of available Hypoglycemic Triterpenoids and Saponins to cure Diabetes mellitus
No full textDiabetes mellitus is a condition when excess amount of sugar is excreted out in the urine. It is probably caused due to hyperglycemia; when body fails to produce sufficient amount of insulin which may utilize or help to store these excessive carbohydrates. When a body does not produce sufficient insulin or to help utilize carbohydrates, it results in the accumulation of unutilized sugar in the blood, the condition is termed as hyperglycemia whereas the condition of passing off the excess sugar in the urine is known as diabetes mellitus. The excretion of sugar makes a profound effect on health that may lead to disability and death. According to some studies, it may cause myocardial infarction, cardiovascular disorders and terminal nephritis. These complications are reported to be the most important causes of mortality and the principal cause of irreversible blindness. There are hundreds of millions of patients around the world suffering from this disease and the number is spreading with an alarming rate. Such a condition has inspired the therapists to develop the methods which help in controlling this malaise. In this article, we have summarized some of hypoglycemic agents from natural sources especially from plants. Since there is a vast number of plants, which are reported to be utilized traditionally in the crude form for diabetes cure in the past. This article is meant to mention only the hypoglycemic ingredients of triterpenoids origin. This information can be helpful in getting new and more effective drugs in future by utilizing unexplored plants which are reported in the literature to possess hypoglycemic activity. This current review is comprised of the relevant work done up to the year 2007 based on search from Google
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
