Risk of Water-Borne Diseases Outbreak amidst Heatwave in Karachi, Pakistan
Get PDFAt least 450 people have died and several others have been hospitalized over four days (22nd-June 26, 2024) due to the terrible heatwaves that Karachi, Pakistan, is experiencing, with temperatures surpassing 40°C. The Sindh government responded by setting up 77 camps to provide vital hydration during heatwaves. However, these attempts are hampered by Pakistan's severe drinking water problem, a major problem due to the water’s high concentration of harmful substances and bacteria. 33% of deaths and 20-40% of all diseases, including cholera and typhoid, are caused by contaminated water. Research shows that there is considerable pollution present even in filtered water, with a high proportion of contaminated samples in Karachi, Rawalpindi, and Islamabad. During this prolonged heat crisis, the quality of the water in relief camps must be immediately assessed to minimize further health risks and possible disease outbreaks. There is an immediate need for improved water management and safety measures
A Review on Apigenin [4’,5,7-trihydroxy-flavone]–An Emerging Anti-cancer Therapeutic Agent
Get PDFChemotherapy works by halting or decreasing the growth of cancer cells, which multiply rapidly. Apigenin can be used to treat cancer, reduce the likelihood of cancer recurrence, stop or delay tumor growth, or shrink tumors that are causing pain and other issues. Although chemical medications are effective, they have a variety of negative effects due to killing or delaying the growth of healthy cells that grow and divide quickly. Thus anticancer therapies based on natural ingredients are emerging. Among these natural ingredients, Apigenin (Api) is a flavonoid having little toxicity with numerous bioactive qualities. Apigenin has several mechanisms to elicit its actions. Cell cycle arrest, anti-inflammatory, apoptosis, antioxidant activity, anti-carcinogenic, anti-mutagenic, anti-progression and anti-proliferative effects are all examples of Apigenin’s actions. Apigenin is involved in regulation of several proteins and factors such as Bcl-xL, Bcl-2, TNF-α, HIF-1alpha, VEGF, etc., modulation of different cellular pathways such as TRAIL, PI3K/Akt/Mtor, JAK/STAT, Wnt/β Catenin & MAPK and regulation of signal transduction. Apigenin is effective in treating and preventing various prevailing cancers including, Breast, cervical, ovarian, colon, oral, prostate, lung, liver, leukemia, lymphoma, melanoma, etc. Apigenin can be used synergistically with cisplatin, 5-fluorouracil, Taxol (Paclitaxel), IFN-gamma, Bcl-2 inhibitors (ABT-263 & HA14-1), Doxorubicin, Chyrophanol and several nano-formulations. Apigenin is also involved in the inhibition of cyclin A, cyclin B & cyclin-dependent kinase-1 [CDK1] expression and Decrease in AKT, P70RSK, and S6 Phosphorylation whereas increasing ERK1/2 and P90RSK phosphorylation
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
