Tongue rolling and hand clasping among various ABO blood groups in a University community in Eastern Nigeria
Get PDFMorphogenetic traits are physical observable traits that can be inherited either in a single gene or multifactorial pattern. ABO blood group is a codominant inherited trait that has been associated with different anatomical and physiological variations. However, there are limited studies that have linked ABO blood groups with some morphogenetic traits.
This study was conducted to ascertain the distribution of morphogenetic traits like hand clasping and tongue rolling among ABO blood groups in a University community in Eastern Nigeria.
A total of 115 volunteers participated in the study. The blood groups of the participants were determined and the expression of the morphogenetic traits was gotten by physical observation. Greater proportion of the participants were males (55.65 %), students (61.74 %) and within ages 15−25 (58.26 %). There was a higher prevalence of blood group O (57.39 %), tongue non-rollers (53.04 %) and right hand clasping (74.78 %) among the participants. The participants with blood groups A and O recorded a higher distribution of tongue non-rollers while those with blood groups B and AB recorded an equal number of both tongue roller and non-rollers. The participants with blood groups A, B and O recorded a higher distribution of right hand clasping while those with blood group AB recorded a significant higher distribution of left hand clasping (P<0.05).
In conclusion, morphogenetic pattern of tongue rolling could not be associated with ABO blood group, whereas that of left hand clasping was associated with blood group AB suggesting that individuals with blood group AB is likely to exhibit left hand clasping; forming basis for determination of hand clasping using ABO blood group in future advancement of genetics and forensic scienc
Administration of chemically ripened banana (Musa acuminate) juice to male Wistar rats depletes blood cells via impaired hematopoiesis
Get PDFThe use of chemicals such as calcium carbide to ripen fruits instigates toxicity; inclusion of the chemically ripened fruits in the preparation of juices may induce blood cells depletion by altering hematopoiesis via declined functionality of erythropoietin, leukopoietin, thrombopoietin, interleukin-3, prostaglandins, hematopoietic stem cells; resulting to reduction in cellular components of blood. The blood cell depletion potentials of chemically ripened banana juice were investigated in 20 male Wistar rats categorized into four; Group A (control), Group B (administered naturally ripened banana juice), Group C & D (administered juices composed of 15mg/kg and 25mg/kg of calcium carbide ripened banana) (n=5). Following the administration protocol of the banana juice for 28days, data was obtained and statistically analyzed using GraphPad prism (version 8). Chemically ripened banana juices significantly decreased erythropoietin, leukopoietin, thrombopoietin, interleukin-3, prostaglandins (PGE2), hematopoietic stem cells and cellular components of blood in a dose-dependent manner. Reduction in packed cell volume (PCV), hemoglobin concentration and increase in erythrocyte sedimentation rate (ESR); which suggests indication of anemia and red blood cell inflammation were also observed. The study suggests that chronic consumption of calcium carbide ripened banana juices induces alteration of hematopoiesis which results to depletion of blood cells.  
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
EVIDENCE-BASED OCCUPATIONAL RISK OF CORONAVIRUS DISEASE (COVID-19) AMONG HEALTH WORKERS
No full textIntroduction: Epidemiologic variables (prevalence and impact) of coronavirus disease were evaluated among health workers to elucidate the occupational risk of frontline fighters of the viral infection.
Methods: This is a descriptive study performed from September to December 2021 on all consenting healthcare workers (HCWs) in a health facility in southern Nigeria. Data collected were statistically analyzed using SPSS version 23.
Results: About 339 volunteered HWs consisting of doctors 88 (26.0%), nurses 78 (23.0%), midwives 54 (15.9%), laboratory scientists 32 (9.4%), pharmacists 21 (6.2%), Public Health Surveillance Officer 29 (8.6%), psychosocial counselor 11 (3.2%), administrative officers 17 (5.0%) and others 9 (2.7%) were involved in the study. About 98 (28.9%) were COVID-19 patients while 241 (71.1%) were healthy. Among 98 unhealthy HCWs, 55 (56.1%) were male, and 43 (43.9%) with an age range of 18 – 79 years. The symptoms distribution produced among the unhealthy volunteers included; fever 12 (12.2%), dry cough 17 (17.3%), productive cough 6 (6.1%), Dyspnea 7 (7.1%), Anosmia 9 (9.2%), headache 8 (8.2%), fatigue 8 (8.2%), Myalgia 4 (4.1%), Aguesia 6(6.1%), Diarrhea 4 (4.1%), sore throat 5 (5.1%), Rhinorrhea 3 (3.1%), Vomiting 2 (2.0%) and Others 7 (7.1%). The study also showed that there was a significant distribution of anxiety and depression among the frontline fighters, P<0.05.
Conclusion: The distribution and impact of the virus observed among clinical and clinical support staff in this study provided an evidence-based occupational risk of the virus on HCWs, especially the frontline fighters; Hence, forming a basis for the need to put in place measures to manage and curtail the viral infection rate in hospital facilities in addition to enhancing prevention behavior of HCWs
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
