material for industrial purposes. This study is focused to prepare a biocomposite of biosilica isolated
from sugarcane baggase and combined with silk fibroin (SF) and polyurethane (PUF) foam. FTIR,
XRD, TGA, DSC and SEM measurements were used to characterize the synthesized BS/SF/PUF
biocomposite. The potentiality of biosilica composite as an antimicrobial support material was
investigated. The BS/SF/PUF biocomposite has a rough surface nature, amorphous and higher thermal
stability due to strong contacts, according to the characterization data. Furthermore, the results revealed
that the produced material exhibited excellent antioxidant and antimicrobial properties.
Silver Nanoparticles Mediated through Aqueous Leaf Extract of Ageratina adenophora Inhibit

Published: June 2022

An enhanced anticancer properties of Ageratina adenophora mediated silver nanoparticles (AgNPs)
were evaluated in the present study. The biogenic AgNPs effectively inhibited the viability and
proliferation of ovarian teratocarcinoma cells (PA-1) by significantly increasing the initiation of
apoptosis. The AgNPs were synthesized with the phytochemicals present in aqueous extract of Ageratina
adenophora leaves which performed the dual function of reducing silver ions as well as the capping
the nanoparticles. Characterization of nanoparticles with UV-vis spectroscopy revealed surface plasmon
resonance peak at 470 nm. Fourier transform infrared spectrum showed the presence of functional
groups such as alcohol, aldehyde, alkane, aromatic amines and phenolic compounds. X-Ray diffraction
(XRD) analysis revealed the crystalline nature and face centred cubic structure of AgNPs. The size,
morphology and distribution of AgNPs were confirmed with scanning electron microscope (SEM).
Further, dynamic light scattering (DLS) and zeta potential measurements also confirmed the size and
charge of the synthesized nanoparticles. The AgNPs significantly increased the cytotoxicity and inhibited
the proliferation of PA-1 cells. Apoptosis of PA-1 cells were increased with treatment of AgNPs. The
increased cytotoxicity of PA-1 cells was due to the synergistic activity of phytochemicals and AgNPs.
Hence, the current research on the silver nanoparticles mediated through A. adenophora leaf extract
could be an effective alternative in treatment of ovarian cancer.

Published: June 2022

The impacts of carbon-based sources on anaerobic digestion methane generation were investigated in
this study. The study revealed that bio-solids and hydrochars may increase accumulative methane
output by 16% to 30%. Nevertheless, there is no significant difference (statistically) (p > 0.05) in
methane production from hydrochars and biosolids generated at, unlike temperatures. Biosolids and
hydrochars augmented microorganisms that may contribute indirect interspecies electron transfer.
Microorganisms’ direct interspecies electron transfer (DIET) in a stable environment created by
carbon-based compounds with homogeneous dispersion and electrons were transported via an aromatic
functional group on the surface of the material. From the fermented effluent, sludge recapture was
0.09 m3 sludge/m3 wastewater. The time required to recoup investment was calculated to be 3.72
years. This study suggested that the impact of surface characteristics of carbon-based sources on
methane generation in anaerobic fermentation and proposes a novel method for reusing discarded tea
grounds.
Perspectives: a round-table discussion on decolonial pedagogies
Authors: Dovey Lindiwe , Mangalanayagam Nina , Mistry Jyoti
Published: June 2022

Three practitioners – a film-maker, a photographer and a film curator, all working in higher education, teaching film production, photography and film studies – discuss their reflections on co-convening a decolonising pedagogy workshop–conference hosted in May 2019 at HDK-Valand, University of Gothenburg, Sweden. They draw from their unique geographical positions – South Africa, Sweden and the UK respectively – to reflect on the nuances and differences of how race and subjectivity shape classroom interactions with the curriculum, and the institutional challenges in developing transformational pedagogy practices. The conversation uses as its impetus this shared experience of co-convening and facilitating the ‘Decolonising pedagogy: Exploring processes in image-making’ workshop–conference, and leads to discussion of broader issues of historical conditions and the geopolitical contexts that have determined the subsequent impact and outcomes in their different universities.

Authors: Linhares Layanne Vieira , Torres Ana Raquel Rosas , Pereira Cícero Roberto
Published: June 2022

The development of measures that assess individual differences in the Belief in a Just World plays an important role in advancing research in this area. The intent of this article was to validate a new version of the Belief in a Just World Scale based on Popular Sayings (BJWPS), proposing that this measure may be an alternative to the original scale. For this, two studies were developed: Study 1 (N=160) aimed to presenting psychometric evidence for a new version of the BJWPS scale through an exploratory factor analysis. Study 2 (N=144) aimed to verify the goodness-of-fit of the proposed measurement model using confirmatory factor analysis. Results of the two studies indicated a single-factor structure that assesses BJW, which corroborates the theoretical frameworks of the BJW scales. Together, the results allow us to conclude that the BJWPS presented satisfactory psychometric indexes.
Politics and Testimony. Political Implications of Jan Patočka’s and Edith Stein’s Testimony
Authors: Szalay Mátyás
Published: June 2022

I investigate the complex relationship between politics and philosophy by focusing on the notion of testimony. I argue that there is a necessary and fruitful tension between sapiential and political life. Testimony is characterized here as a free value-response in an intersubjective relation that requires empathy on both sides of the communication. This act of affirming a truth or value goes beyond the limits of prudent self-realization and self-preservation: authentic testimony requires some kind of self-sacrifice. I contrast this general image of testimony to Jan Patočka’s interpretation of «care for the soul». Patočka, by following the early Husserl’s renewal of philosophy, managed to establish and to preserve the harmony between theory and praxis even during persecution of the communist regime. His courageous acts come close to and illuminate the testimony of Edith Stein, who set the measure for philosophical authenticity and self-donation. The comparison of these two testimonies helps to elaborate the notion of exemplary sapiential life — a highly relevant notion for politics.

Published: June 2022

This article analyses the developments and strategies experienced by the ikat weaver in Kediri, especially in the Village Bandar Kidul, District Mojoroto. This study used the critical history method. It emphasizes primary sources in the form of written sources from newspapers and the oral history method. According to the result, ikat weaving in Bandar Kidul began to develop when a Chinese resident, Freddy Jie, in the 1950s opened the ikat weaving business which affects the livelihoods of the residents of Bandar Kidul. They have depended on one sector of livelihood and the industry has begun to grow. Due to its motifs and production tools, the ikat production from the village of Bandar Kidul has a good and potential market demand. However, the monetary crisis in 1997-1998 hit the industry and began to down. From the end of the 1970s to the late 1990s, the Bandar Kidul ikat craft began to experience a downturn due to being unable to compete with factory-made woven fabrics and the absence of successor regeneration after most of the business’ founders died. However, entering the mid-2000s, the future of the ikat industry was bright because the local government intervened in the industry. Some pieces of training had been held to improve the capabilities of the ikat weaver under dominated by modern equipment.

Authors: Rofi'i Ahmad Faiz , Rochwulaningsih Yety , Alamsyah Alamsyah
Published: June 2022

At the 1952 Nahdlatul Ulama (NU) Congress in Palembang, 1952, NU officially broke away from Masyumi and declared itself a political party. From then on, NU emerged as a growing force in both local and national political scenes. In the 1955 elections in Cirebon, the NU party emerged as the winner and the only branch in West Java that received the most votes. The political strategy of the NU Party in Cirebonin the run-up to the 1955 general election was based on the instructions of the Nahdlatul Ulama Executive Board (PBNU) to immediately organize party activities; among others by recruiting non-party members and preparing funding. The emergence of local kiai (religious leaders) who had extensive networks in the villages and Islamic boarding schools also contributed to the NU party’s victory. After the 1955 elections, the Cirebon NU Party highlighted unilateral actions by the PKI. During the September 30, 1965 Movement (Gestapu), mass killings broke out in Central Java and East Java but similar violence did not occur in Cirebon, though there was small outbreaks of violence. In response to the political situation in Indonesia and considering the situation at the local level, PBNU held its 24th Congress in Bandung 1967. By employing the historical method, this study discusses the political strategy of the NU party in Cirebon Regency before and after the 1955 election.

Published: June 2022

The World War II in Indonesian territory at that time involved the Imperial Japanese Army against the military from the allies and was known later as “Theater of Pacific”. The massive military activities that took place in Indonesian territory during the World War II definitely left a lot of and varied material evidences. However, in fact, many of the material evidences from the World War II have been forgotten due to its dilapidated condition. One of the military operational areas where many evidences of the World War II can be found is South Konawe, precisely at Kendari II Airfield Site, which is now known as HLO Airfield (Halu Oleo Airfield). This research utilized archives and aerial photographs during the World War II combined with direct observation at the site and reconstruction efforts using excavated data. Based on the findings, it reveals the existence of the World War II remains at Kendari II Airfield area. It is also known that the condition of the most massive findings is located in the Japanese military administration and maintenance area during the World War II at Kendari II Airfield area. These remains can certainly be a source of historical writing of the Japanese Government Era in South Konawe.

Mesh scheme for a phase transition problem with time-fractional derivative
Authors: Lapin Alexander
Published: June 2022

The time-fractional phase transition problem, formulated in enthalpy form, is studied. This nonlinear problem with an unknown moving boundary includes, as an example, a mathematical model of one-phase Stefan problem with the latent heat accumulation memory. The posed problem is approximated by the backward Euler mesh scheme. The unique solvability of the mesh scheme is proved and a priori estimates for the solution are obtained. The properties of the mesh problem are studied, in particular, an estimate of movement rate for the mesh phase transition boundary is established. The proved estimate make it possible to localize the phase transition boundary and split the mesh scheme into the sum of a nonlinear problem of small algebraic dimension and a larger linear problem. This information can be used for further construction of efficient algorithms for implementing the mesh scheme. Several algorithms for implementing mesh scheme are briefly discussed.

Published: June 2022

A finite element method for a monolithic quasi-Lagrangian formulation of a fluid–porous structure interaction problem with a corrected balance of stresses on the fluid–structure interface is considered. Deformations of the elastic medium are not necessarily small and are modelled using Saint Venant–Kirchhoff (SVK) constitutive relation. The stability of the method is proved in a form of energy bound for the finite element solution.
„Mir langt der Heiland“
Authors: Bigalke Bernadett
Published: June 2022

In diesem Aufsatz wird erstens der Frage nach den gesellschaftlichen Umgangsweisen von europäischen Gesellschaften der Neuzeit mit religiös gerahmter, weiblicher Nahrungsabstinenz nachgegangen. Zweitens werden Überlegungen dahingehend angestellt, welche Bedingungen und Faktoren für die Persistenz dieser relativ marginalisierten Praxis im untersuchten Zeitraum ausgemacht werden können. Dabei wird in der Argumentation für einen wissensgeschichtlichen Ansatz plädiert. Mit diesem Instrumentarium können u. a. auch hybride Erklärungsweisen der historischen Akteure rekonstruiert werden, die nicht einfach den Kategorien „natürlich“ bzw. „übernatürlich“ zugeordnet werden können. Der Gegenstand der Fallstudie sind nahrungsabstinente Katholikinnen Westeuropas im Zeitraum von 1780 bis 1980. Nahrungsabstinenz hat dabei auf der objektsprachlichen Ebene sowohl die Bedeutung von Nicht-essen können oder wollen bis hin zur völligen Abwesenheit des Bedürfnisses nach „irdischer“ Nahrung.
Andere Götter, andere Opfer
Authors: Mignon Laurent
Published: June 2022

In den letzten Jahren haben Debatten über die Themenbereiche Vegetarismus und Veganismus auch in der Türkei an Bedeutung gewonnen. Von der islamischen Akzeptanz vegetarischer und veganer Lebensstile bis zur Frage nach dem Tierwohl werden ernährungsbezogene Themen häufig in den Medien diskutiert. Weniger bekannt ist, dass schon in der ersten Hälfte des 20. Jahrhunderts führende Intellektuelle und Literat*innen sich mit Vegetarismus aus ethischer, religiöser und ideologischer Perspektive auseinandergesetzt haben. Interesse für indische Religionen, neuheidnische Strömungen und alternative Lebensweisen, rechte Ideologien und islamischer Reformismus sind einige der intellektuellen und politischen Entwicklungen, die zu diesen Auseinandersetzungen geführt haben. Durch die Betrachtung von Hasan Ferit Cansevers und Asaf Halet Çelebis kritischen Ansätzen gegenüber dem Monotheismus und ihres aktiven Vegetarismus wird es möglich, über eine Geschichte der Religionen in der späten osmanischen und frühen republikanischen Türkei nachzudenken, die über die Untersuchung der Vielfalt innerhalb des Islams, des Status der christlichen und jüdischen Minderheiten und des Aufstiegs der säkularen Ideologien hinausgeht. Die Untersuchung der Ernährungsnormativität bietet im Falle der Türkei die Möglichkeit, zu einer anderen Geschichte der Religionen in der Türkei beizutragen.
Normierung von Essen in der Jōdo Shinshū: Zum Verhältnis der Norm zur schulspezifischen Lehrauslegung des Buddhismus
Authors: Rüsch Markus
Published: June 2022

Das Verbot des Fleischverzehrs kann als ein besonders zentrales Element buddhistischer Esskonventionen bezeichnet werden. Auch wenn die allmähliche Entwicklung hin zu dieser Regel sowie Abweichungen von ihr bereits häufiger in der Forschung thematisiert wurden, ist der Fleischverzicht nach wie vor eine diskursbestimmende Orientierungsgröße, der gegenüber sich konforme oder abweichende Bräuche positionieren müssen. Die japanischen Buddhismen stellen dabei Prototypen dieses Verhältnisses dar, da der Großteil von Mönchen und Nonnen in der Gegenwart offen das Fleischverzehrverbot nicht einhält. Heißt dies aber allein, dass derartige Teile des Alltags lediglich von einer „buddhistischen“ Seite des Lebens getrennt vorgestellt werden? Innerhalb des Aufsatzes zeige ich, wie die Schule Jōdo Shinshū eine eigene Normierung der Handhabung und des Verspeisens von Essen entwickelt hat. Diese unterscheidet sich dezidiert von einer fleischlosen und streng ritualisierten Art zu essen, die heute als Diskurselement oder zeitlich begrenzte Praxis noch in den meisten buddhistischen Schulen präsent ist. Anhand einer Untersuchung von dargebotenen Speisen, Mahlzeiten zu besonderen Gelegenheiten sowie Tischgebeten zeige ich, wie diese Normierungen zu einem maßgeblichen Anteil das Buddhismusverständnis der Jōdo Shinshū zum Ausdruck bringt.
»Die mittelalterliche Architektur ist nun einmal durchaus international«: Anmerkungen zu Ingo Herklotz, Richard Krautheimer in Deutschland: Aus den Anfängen einer wissenschaftlichen Karriere 1925–1933
Authors: Seiler Peter
Published: June 2022

In Richard Krautheimer in Deutschland, Ingo Herklotz explores the beginnings of Krautheimer’s academic career. Based on a wealth of previously unpublished sources, he argues that Krautheimer’s groundbreaking essays “The Carolingian Revival of Early Christian Architecture” and “Introduction to an ‘Iconography of Medieval Architecture’” reach back to his early days in Weimar Germany. Herklotz also contends that the young scholar’s early writings show a one-sided orientation toward methodological concepts of an autonomous history of style and a striving for a “German national identity”. However, neither contention seems plausible. As can be demonstrated, Krautheimer had already taken a vigorously European view on medieval architecture in his dissertation on the architecture of the mendicant orders in Germany and in his book on synagogues, and indeed realised the potential of cultural-historical context analyses early on.
Editorial: Special Section on Durability, Functionality, and Sustainability of Road Materials and Structures
Authors: Guo Meng
Published: June 2022

With the emergence of extreme climate and increasing traffic load in recent years, the performance requirements for transportation infrastructure materials are increasing. Sustainable transportation infrastructures have attracted much attention from the research community and industry. Building and preserving efficient, reliable, and sustainable roads is crucial for economic and social development. The design of road materials and structures significantly influences road durability. The main components of road materials are bitumens, additives, bituminous mixes, asphalt concrete, cement concrete, unbound granular materials, soils, and geo-composites. The new and innovative materials, mix design, soil stabilization, and environmental aspects of handling and reuse of road materials are also crucial. The road performance can be affected by vehicle loading and environmental conditions including light, temperature, oxygen, and moisture, etc. An accurate assessment of road performance, stress and strain state, and the environmental effects has always been a challenge faced by this industry. This special section of Journal of Testing and Evaluation published by ASTM International includes 15 peer-reviewed papers. These papers introduce recent work that furthers an understanding of durability, functionality, and sustainability of road materials and structures and covers diversified topics such as the following: (1) mechanism study of road material performance including aging, recycling, and fatigue; (2) development and evaluation of innovative materials or technologies in road engineering including natural rubber latex composite modified asphalt, subgrade geogrids, polyether polyurethane concrete, basalt fibers, and cement mortar used in prefabricated road base; (3) performance evaluation of road materials and structures including polishing and anti-skidding; (4) mechanical analysis of road structures including modulus back-calculation of road structure, dynamic response of deck pavement, and monitoring and evaluating mountain-expressway slope safety. This special issue also lays out an interdisciplinary framework that not only aims to advance specific areas of science and engineering but also to help advance the state of practice in road engineering. Last but not least, I would like to extend my warm thanks to all the reviewers that kindly agreed to evaluate all the articles and contributed to the scientific quality of this special issue.

Authors: Dib González Zoraya Hussein , Guerra-Hernández Elisabet , Fariña-Castro Roberto
Published: June 2022

Necrotizing fasciitis is defined as a rapidly progressive infection of the skin and soft tissue that usually involves severe systemic toxicity. The incidence of this infection has increased in the last few decades and is estimated to affect one out of every 100000 habitants in western European countries. This disease is the most serious form of skin and soft tissue infection, due to the rapid destruction and necrosis of the fascia and subcutaneous fat, and the development of shock and multiorgan failure of one third of the patients. The diagnosis and early treatment with aggressive surgical debridement, broad-spectrum antibiotic therapy and hemodynamic support measures are essential3. This is a surgical emergency. We can show two necrotising fasciitis cases from different locations and different outcomes, which highlights the importance of the anatomical area affected by the infection for the control and eradication of the focal point. And the importance of early diagnostic suspicions and early and aggressive actions to eradicate the infection.

Published: June 2022

Introduction The main hormonal treatment of estrogen sensitive breast cancer includes the use of selective estrogen receptor modulators, aromatase inhibitors and GnRH-Analogs. It has been observed that administering aromatase inhibitor to breast cancer patients not only impairs their glucose metabolism but it can even cause frank diabetes mellitus. Moreover, it has been hypothesized that aromatase inhibitors may have an impact on glucose metabolism by their effect on estrogen levels. Therefore, we designed an experiment in order to assess the effect of estrogens on insulin secretion from rat beta pancreatic insulinoma INS-1 cells. Methods Experiments were conducted on an INS-1 cell line, a rodent beta cell line derived from a rat insulinoma induced by X-ray irradiation, which displays high insulin content, production of both proinsulin I and II and responsiveness to glucose and hormones. INS-1 cells were routinely cultured in 75cm2 flasks (T75) containing 10ml of appropriate culture media and then were transferred into 6-well plates and treated with 17β-E2. Proliferation, as well as insulin expression in the 17β-E2 treated cells in mRNA and protein level was then investigated. Cell cultures were treated with 12.5mM, 25mM, 50mM, 100mM and 200mM estradiol. After 24 hours, RNA as well as protein extraction was carried out. Gene expression was examined in mRNA and protein level, by real time quantitative reverse transcriptase PCR and by western blotting, respectively. Extraction of total RNA was achieved with the use of NucleoZOL (Macherey-Nagel, Duren, Germany). Protein concentration of samples was measured by using the bicinchoninic acid (BCA) assay and bovine serum albumin (BSA) as the standard (Thermo Scientific TM Pierce TM BCA Protein Assay Kit, USA). Results Real time PCR showed a dose-dependent up regulation of insulin gene expression by estradiol. The findings were consistent with the results from western blot, although the estradiol dose-dependent increase in gene expression was not so clear. Finally, both protein and mRNA expression of insulin increased in a dose dependent manner, with mRNA reaching a plateau at 100nM estradiol treatment. Conclusion The experimental data suggest that there might be a direct effect of estrogen on beta cells and insulin secretion.

Authors: Kumar Goyal Pawan , Sharma Lav , Singh Rathore Sandeep , Kapoor Suruchi
Published: June 2022

Background Coronary Artery Disease (CAD) is a common cause of premature morbidity and mortality in diabetics and is often asymptomatic because of silent myocardial ischemia (SMI). Early detection of SMI may prevent catastrophic cardiac events. Objective To study the prevalence of SMI in patients of type 2 diabetes mellitus (Type 2 DM), asymptomatic for CAD and to assess the role of conventional CAD risk factors in diabetic patients asymptomatic for CAD in the development of SMI. Methodology 102 cases of Type 2 DM without any clinical and electrocardiographic evidence of CAD, who attended a tertiary care hospital in North Delhi, over a period of one year, were studied for the present cross-sectional study. Detailed history, general physical examination, BMI, systemic examination and investigations like glycosylated hemoglobin (HbA1c), lipid profile, resting 12-leads electrocardiography (ECG) and treadmill test (TMT) were carried out. Results Out of 102 patients, TMT was found positive in 23 patients. It was positive in 12% among diabetic patients with duration of diabetes ≤5 years, 14.8% in patients with duration 6-10 years, 37.5% in patients with duration 10-15 years and 77.7% in patients with duration 16-20 years, respectively with p<0.001. Conclusion The prevalence of SMI in asymptomatic Type 2 DM without history of CAD is 22.54%. Duration of diabetes, presence of autonomic neuropathy (AN), dyslipidemia and HbA1c level are strong clinical predictors of SMI in asymptomatic Type 2 DM.

Published: June 2022

Sedentary lifestyle is associated with detrimental health effects on bone. Risk of fracture and lower bone mineral density (BMD) are increased among people with lower physical activity level. The onset of osteoporosis does not occur immediately. Instead, it slowly progresses throughout the years. The ideal approach and easier way to prevent or delay the onset of osteoporosis should focus on changing one’s lifestyle by including higher amount of physical activity. Exercise or higher amount of physical activity helps to impose mechanical strain on the bone, and stimulate bone metabolism process. However, different exercise mode might impose different effect on bone metabolism. This review paper will focus on bone remodelling, bone formation and resorption markers, and effects of physical activity or exercise on bone metabolism markers.

Published: June 2022

In North East region of India, iron toxicity is one of the major problems in culture fisheries. To overcome this challenge, it is necessary to identify the role of ferritin protein as an iron detoxificant and store in fishes. The Heavy chain in a ferritin protein possess di- Fe binding site in the fourth helix that interacts with oxygen. In this paper attempt has been made to study the structure and function of ferritin heavy chain subunit of Oryzias latipes from amino acid sequence. Physicochemical characterization by Expasy ProtParam form tools reveals that the protein is acidic, unstable and hydrophilic. A hydropathy scale showed two peak with significant score above the threshold value (0 to + value) but TMHMM conclude that there were one transmembrane domain within protein. The secondary structures contain alpha helix (56.50%), extended strands (10.73%) and coiled region (32.77%). The query sequence shows homology to the selected template (structure of mouse heavy chain modified ferritin by X-ray diffraction technique) with maximum % identity. To analyse the phylogenetic relationship, ML tree was constructed between Oryzias latipes and Oryzias melastigma for the ferritin heavy sub unit along with Cyprinus carpio as out crossed. Two distinct clads formation was observed between same genus species and the out crossed species. In protein-protein interaction analysis via STRING 10.0 tool, two enriched pathways of KEGG, six Inter Pro domains, one PFAM protein domain, one Uniprot keywords and eleven functional parameters of network analysis were identified in Oryzias latipes. The overall investigation reveals the structural features and their association in detoxification and iron homeostasis.

Histopathological Changes Induced by Chronic, Sub- Lethal Diazinon Exposure in Alligator Gar (Atractosteus Spatula) Tissues
Authors: Omar-Ali Ahmad , Petrie-Hanson Lora
Published: June 2022

Diazinon is a widely used household and agricultural pesticide that accumulates in the aquatic environment and adversely affects non-target organisms such as mammals, birds, and fish. Sub-lethal pesticide levels occur in natural waters, and can impact the health, physiology and fitness of fish populations. This study was conducted to assess the effects of chronic, sub-lethal diazinon exposure to skin, liver, kidney, spleen, heart, gut, intestine, and gas bladder tissues of alligator gar, Atractosteus spatula. In two studies, gar were exposed to sub-lethal concentrations of 0.01, and 0.1 mg/L diazinon for 15 and 30 day periods. Skin, gills, liver, and kidney of exposed fish demonstrated remarkable microscopic lesions. These changes included skin lesions in the head and body, which started as white spots and progressed into deep ulcerations, hepatic vacuolation, swollen hepatocytes, steatosis, aggregation of macrophages, necrosis, and hepatic fibrosis. Gill tissues demonstrated epithelial hyperplasia in the secondary lamellae. Vacuolar degeneration was also present in the hematopoietic tissues of the kidney. Lesion occurrence and severity were correlated to increased diazinon dose and exposure time. Our findings revealed the harmful effects of chronic, sub-lethal diazinon exposure on alligator gar, and suggest other aquatic organisms may also be affected by sub-lethal concentrations of pollutants in their environment.

Objective

Parathyroid carcinoma is a rare tumor among parathyroid tumors. Aspiration cytology and needle biopsy are generally not recommended for diagnostic purposes because they cause dissemination. Therefore, it is commonly diagnosed by postoperative histopathological examination. In this study, we investigated whether preoperative inflammatory markers can be used as predictors of cancer in patients with primary hyperparathyroidism.

Design

This was a retrospective study.

Methods

Thirty-six cases of parathyroid carcinoma and 50 cases of parathyroid adenoma (PA) operated with the diagnosis of primary hyperparathyroidism and confirmed histopathologically at Ito Hospital were included in this study. Preoperative clinical characteristics and inflammatory markers (neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio (LMR)) were compared and their values in preoperative prediction were evaluated and analyzed.

Results

Preoperative intact-parathyroid hormone (P  = 0.0003), serum calcium (P  = 0.0048), and tumor diameter (P  = 0.0002) were significantly higher in parathyroid carcinoma than in PA. LMR showed a significant decrease in parathyroid carcinoma (P  = 0.0062). In multivariate analysis, LMR and tumor length diameter were independent predictors. In the receiver operating characteristics analysis, the cut-off values for LMR and tumor length diameter were 4.85 and 28.0 mm, respectively, for parathyroid cancer prediction. When the two extracted factors were stratified by the number of factors held, the predictive ability improved as the number of factors increased.

Conclusion

In the preoperative evaluation, a combination of tumor length diameter of more than 28 mm and LMR of less than 4.85 was considered to have a high probability of cancer.

Published: June 2022

Background

There is no consensus regarding markers of optimal treatment or timing between glucocorticoid intake and assessment of hormone levels in the follow-up of female 21-hydroxylase deficient patients.

Objective

To examine visit-to-visit repeatability in levels of adrenal hormones in adult female patients, to identify predictors of repeatability in hormone levels and to examine concordance between levels of different adrenal hormones.

Method

All patients with confirmed 21-hydroxylase deficiency treated with glucocorticoids, were included. The two most recent blood samples collected on a stable dose of glucocorticoid replacement were compared. Complete concordance was defined as all measured adrenal hormones either within, below or above normal range evaluated in a single-day measurement.

Results

Sixty-two patients, median age of 35 (range 18–74) years were included. All hormone levels showed moderate to excellent repeatability with an intraclass correlation coefficient between 0.80 and 0.99. Repeatability of hormone levels was not affected by the use of long-acting glucocorticoids or time of day for blood sample collection. The median difference in time between the two sample collections was 1.5 (range 0–7.5) h. Complete concordance between 17-hydroxyprogesterone, androstenedione, and testosterone was found in 21% of cases.

Conclusion

During everyday, clinical practice hormone levels in adult female patients with 21-hydroxylase deficiency showed a moderate to excellent repeatability, despite considerable variation in time of day for blood sample collection. We found no major predictors of hormone level variation. Future studies are needed to address the relationship between the timing of glucocorticoid intake vs adrenal hormone levels and clinical outcome in both adults and children.
Mortality and Epidemiological Transition of the Lithuanian Population in 1849–1921
Authors: Bugienė Dovilė
Published: June 2022

With the modernization of societies, mortality is one of the key factors in the process of population change. Mortality since the middle of the 20th century in Lithuania has been widely studied in various aspects. However, the previous historical period in this field is still little studied and data on the changes in the development of Lithuanian mortality are almost unavailable. This article presents a study on the basis of the information from Roman Catholic churches death records books to reconstruct the structure of causes of death in the Lithuanian population in 1849–1921, its differences between urban and rural areas, and the links with A. R. Omran’s theory of epidemiological transition. The data of death records suggests the epi­demiological transition in Lithuania began at the end of the 19th century – the beginning of the 20th century and displays the influence of the type of place of residence on the pace of mortality change.

Background and Study Aim. The variability of interpopulation morphofunctional traits in humans is closely related to various environmental factors. However, body composition has a significant relationship with indicators of physical fitness, human performance, with its adaptation to environmental conditions. The aim of the work is to investigate ethno-territorial variability of morphological characteristics of students studying at Ukrainian universities. Material and methods. Datum were from cross-sectional surveys since 2014 through 2019. Male students aged 18–25 years old (n = 488) of Ivano-Frankivsk National Medical University from different countries were recruited. Anthropometric methods included body length (BH), body weight (BW), chest girth in three states: at maximum, maximum inspiration and rest; skinfolds thicknesses and epiphysis measurements. Somatometric physical development indicators (body mass index - BMI), Kettle’, Pignet’, Livi’ and Erismann’ indexes) were calculated on the basis of these parameters. Body composition (absolute and relative amounts of skeletal, fat and muscle components) were determined using Matiegka formula. Results. It was found that the average growth of students in European countries is higher compared to students from Asia (9-10%) and Africa (3-5%). Reliably significant differences (p <.05) in body weight indicators between all ethnic groups were found. Students from India are characterized by very low levels of relative body fat. Most representatives of Egypt (61.4%) and Jordan (50.9%) are characterized by moderately high fat content. For representatives of all other countries, this figure is within the optimal ratio. Conclusions. The obtained results showed that anthropometric and morphometric indicators of students aged 18-25 change statistically significantly depending on the ethno-territorial factor. Thus, the study of ethnic variability of morphological characteristics is of great importance for the individualization of physical training of students from other countries in higher education institutions of Ukraine.

Published: June 2022

Some results on the sets of almost convergent, statistically convergent, uniformly statistically convergent, $I$-convergent subsequences of $(s_{n})$ have been obtained by many authors via establishing a one-to-one correspondence between the interval $(0,1]$ and the collection of all subsequences of a given sequence $s=(s_{n})$. However, there are still some gaps in the existing literature. In this paper we plan to fill some of the gaps with new results. Some of them are easily derived from earlier results but they offer some new deeper insights.

Published: June 2022

Abstract: Reinforced concrete elements with a high longitudinal and transverse reinforcement ratio may present conflicts on both of them, resulting in reduced labor productivity and a poor job when assembling the transversal reinforcement, reducing its effectiveness. Thus, this research presents a type of internal transverse reinforcement as an alternative to mitigate this conflict between the transverse and longitudinal bars. A total of 5 reinforced concrete wide beams were made, one of them as a reference with closed stirrups, and the other ones with internal stirrups, varying the inclination of the internal transverse reinforcement in 60° and 90°, and the number of vertical legs of the internal transverse reinforcement used. Comparing the results of the beams with internal stirrups with the reference beam, it was observed that the internal stirrups provided increases of up to 14% in shear strength when compared with the closed stirrup.

Gifted student education has been the centre of many studies to this day. Even though there was an amount of studies examining gifted education there was limited amount of studies related to self-efficacy levels of English Language Teachers for gifted students. Therefore the aim of this study is to determine the self-efficiency levels of English Language Teachers towards gifted student education and to examine teachers’ age, pofessional seniority levels and gender variables. This study was carried out with 352 volunteer English Language Teachers (291 women, 61 men) who worked in the 2020-2021 academic year in the Educational Institutions related to the Ministry of National Education in Turkey. As a result, it was found that self-efficiency beliefs of English Language Teachers towards education of gifted students in both sub-dimensions and total scores of the scale were around 80 out of 100. Therefore it was revealed that teachers’ self-efficacy beliefs were high. Also, the results of the analysis showed that self-efficiency beliefs of English Language Teachers towards the education of gifted students increased with the age variable. In addition to these results, it was found that the self-efficacy beliefs of English Language Teachers increased as their teaching Professional seniority levels increased. Lastly, there was no significant difference in the whole scale and its sub-dimensions related to gender variable. In addition to that, literature review of the studies about teachers’ professional seniority and gender variables revealed that, a consensus could not be reached. In order to eliminate this ambiguity, further studies are needed on this subject. On the other hand analysis of the scale revealed that self-efficacy scores of English teachers in subjects such as behavior control, implementation of the Individual Education Program and classroom control were lower than the other items.
