Hormonal profile peculiarities on pancreatic, thyroid and suprarenal hormones in nigeria
No full textApproximately 4,5% of Nigerians had diabetes mellitus in 2019 (O.Oguejiofor et al., 2019). Insulin-dependent diabetes mellitus comprises only less than 3% of all the patients, had double increase from 2019th values and showed 21,7% of people (M.Adeyemi Olamoyegun et al., 2024), approximately 3,9 mln in 2019 and will be almost 6 mln by 2045 by forecasting (C.E. Nwator et al., 2024). Mostly Nigerian people between 41 and 60 years get sick (O.O.Adevumi et al., 2022). Elevating in fasting blood glucose and glycosylated Hb more than 6,5% are met rather often in Nigeria whiledefining latent and even non-hidden diabetes mellitus, especially in urban populations (C.N. Okafor et al., 2021). Thyroid diseases take the second position among endocrinopathies worldwide as a whole and in Nigeria particularly with a rate of hyperthyreoidism approximately 60% and hypothyreoidism 40% (E.N.Okafor et al., 2019; B.T.Abera et al., 2021), euthyreoid goiter 53% and subclinical hyperthyreoidism 1-2% (J.O. Edah et al., 2023). Thyroid insufficiency impacts onto carbohydrate metabolism at insulin-independent diabetes mellitus at a greater extent than in people without diabetic mellitus (A.K. Jimoh et al., 2022). Water purifiers can disturb iodine capture by thyroid gland (G.Lisko et al., 2020). Nigerian females get sick on Graves’ disease at a greater extent than males (E.N.Okafor et al., 2019), even with ratio 5:1 on it (A.O. Ogbera et al., 2024) and 20:1 on all thyroid problems (J.O. Edah et al., 2023). Adrenal insufficiency has not only acquired but inheritant character (T.R.P.Mofokeng et al., 2022). Approximately 30-32% of the patients were reported to have low baseline serum cortisol level (I.E.Akase et al., 2019). Cushing’s syndrome was reported to be in adolescent girls (A.E.Edo et al., 2022), adult females (R.Mumini et al., 2024) with female:male ratio 4-5:1 (K.A.A. Abolanle et al., 2020), more seldom morbidity in children. As a whole, it is considered to be met relatively rarely in Nigerian population (R.Mumini et al., 2024)

Hemoglobinopathies types and their peculiarities in Morocco
No full textThere are two forms of thalassemia – alpha- and beta-, though clinically thalassemia is divided into minor, intermediate and major. Beta-thalassemia rate is 6-7% in Morocco (S.S. Khandker, 2023) with prevalence in Casablanca 5% among all cities (S. El Kababi, 2019), alpha-thalassemia 0,96%, particularly in the North (A.Laghmich et al., 2019), minor form 1,2% in a whole country. Carriers rate is 6,5% on beta-thalassemia (N.Marzouki, 2022), alpha-thalassemia 0,30% (I.Belmokhtar et al., 2025) and 8% on both thalassemia types (A.Laghmich et al., 2019). Morocco East became thalassemia region after its North and West (I.Belmokhtar et al., 2022). In Rabat, there was a research set which results demonstrated beta-thalassemia major dependence on HLA antigens of both I and II class (S. Ouadghiri et al., 2024). Novel beta-thalassemia variants (C6(-G) and -83(A>G) as well as Hb structural variant D-Ouled Rabah have been discovered first in Morocco. Beta-thalassemia represents the most widely-distributed hemoglobinopathy in Morocco while hemoglobinosis C takes the second position, alpha-thalassemia the third, hemoglobinosis G-Philadelphia - the fourth, D-Ouled Rabah and O-Arab the fifth one (I.Belmokhtar et al., 2025). Morocco has hemoglobinosis C representing mutant Hb with glutaminic acid replacement into lysine in its beta-chain 6 th position. Moroccan people have not only softer heterozygous form with no anemy but also harder homozygous form with moderate hemolytic anemy and Hb crystals in blood smears. Hemoglobinosis C is distributed in Southern Morocco at a greater extent (N.Marzouki, 2022). A combination between these Hb types represents more difficult pathological condition by course than separate hemoglobinoses. There are the data according to which beta-thalassemia can be in a complex with hemoglobinoses C and S with especially hard form of the disease, met in Eastern Morocco mainly (I.Belmokhtar, 2022), except Southern part of the country. Northern Moroccan city Kenitra is distinguished by sickle cell syndromes or hemoglobinosis S in children. Sickle-cell anemy carriers rate is 6,5% and morbidity 80% in the North and 10,5% in other parts of the country (N.Marzouki, 2022)

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
