Authors: Agortey Julius Jerry 
Published: May 2023

The purpose of this study was to investigate the effects of sports stressors and academic performance of student-athletes in selected colleges of education in Ghana. The study was guided by two (4) specific objectives: (a) To assess the influence of sporting stress on the academic performance of student-athletes in Colleges of Education in Ghana; (b) To compare the GPA of student-athletes in the year of competitive sports and the year of no competitive sports in the Colleges of Education in Ghana and (e) to recommend ways of managing stress to enhance student athlete’s academic performance. The study adopted a cross-sectional survey design, in which both quantitative and qualitative data were collected. The study was conducted in Ghana. Simple random sampling was used to select student-athletes while purposive sampling was used to select tutors. The target population for this study was 12 tutors and 768 student-athletes in six (6) Ghana Colleges of Education. The total sample size for the study was 335 (12 tutors & 323 students-athletes). The instruments for data collection were a questionnaire, an interview guide and document analyses. Both, descriptive and inferential statistical analyses were done using Statistical Package for Social Sciences (SPSS version 20). Descriptive statistics summarized, organized and described the responses when addressing study objectives through the use of means, standard deviations, frequencies, and percentages. Inferential statistics such as ANOVA and Point biserial were used to test the formulated null hypotheses. All hypotheses were tested at p<0.05 alpha level of significance. The study found that competitive sports stressors have a statistically significant influence on the academic performance of student-athletes in colleges of education in Ghana. The study also revealed that competitive sports stress has a statistically significant influence on the academic performance of student-athletes, especially the females, in colleges of education in Ghana. This study therefore, recommends that female student-athletes be given scholarships to motivate and enhance other female students’ participation in competitive sports. The study also recommends that colleges of Education in Ghana introduce stress management strategies to address stressors’ link to academic performance of student-athlete.
Investigating the Flexural Performance of Basalt Fiber Reinforced Polymer (BFRP) Bars at Elevated Temperatures
Authors: Aween Ahmad Sadq , Mohmmad Sarwar Hasan 
Published: May 2023

The FRP-reinforced concrete constructions may be subjected to elevated temperatures, which may compromise the structural integrity of the bars and, finally, the whole structure. As a result, the thermal stability of the FRP bars needs to be properly examined before they can be completely used in the construction field. Flexural strength testing has been utilized as a standard approach for determining the uniaxial tensile strength of brittle materials since it is less costly and easier to perform than the direct tension test. While the findings achieved were not absolute tensile data, they can offer a prediction of the relative tensile strength of the FRP bars. The flexural behavior of basalt fiber-reinforced polymer (BFRP) bars with different nominal diameters (8.0 mm, 10.0 mm, 12.0 mm, and 14.0 mm) exposed to increased temperatures (up to 150 °C) was examined in this research. According to the findings, when the temperature rises, the stiffness and flexural strength of the BFRP bars reduce. As the temperature approached the glass transition temperature (Tg) of the bars, a significant decrease in stiffness and strength was noted. These outcomes were also seen in other studies' pure tension tests of FRP bars. At higher temperatures, bigger nominal diameter bars are superior to smaller nominal diameter bars in terms of flexural strength decaying resistance. Although a comparable flexural stiffness degradation was noted as temperature increased.

Abstract
Luminous red novae (LRNe) are transients characterized by low luminosities and expansion velocities, and they are associated with mergers or common-envelope ejections in stellar binaries. Intermediate-luminosity red transients (ILRTs) are an observationally similar class with unknown origins, but they are generally believed to be either electron-capture supernovae in super-asymptotic giant branch stars or outbursts in dusty luminous blue variables (LBVs). In this paper, we present a systematic sample of eight LRNe and eight ILRTs detected as part of the Census of the Local Universe (CLU) experiment on the Zwicky Transient Facility (ZTF). The CLU experiment spectroscopically classifies ZTF transients associated with nearby (<150 Mpc) galaxies, achieving 80% completeness for m

Entre ordre et désordre

Les documents posthumes laissés derrière eux par des écrivains, des philosophes et des savants montrent que si le processus de création peut prendre des formes très variées, il n’est, dans la grande majorité des cas, pas le fruit du hasard. Le présent article justifie cette affirmation en prenant l’exemple des fiches bristol ou papier qui ont été utilisées comme technologie d’écriture par le philosophe Hans Blumenberg, le sociologue Niklas Luhmann et l’écrivain Arno Schmidt. Bristol ou papier, les collections de fiches sont la forme moderne prise par la technique de la notation savante qui, depuis le début des temps modernes, a permis de mobiliser le savoir établi. Mais au tournant du xixe et du xxe siècle, les fichiers sont devenus un outil standardisé pour gérer toutes sortes de données. Par le biais d’études de cas, le présent article montre comment les trois auteurs allemands retenus s’approprient au xxe siècle cette technologie standardisée et la détournent en l’adaptant de manière spécifique à leur processus créateur : le fichier « contrôlé » de Blumenberg, le fichier « désordonné » de Luhmann et le fichier « linéaire » de Schmidt conditionnent trois modes de production différents et assignent à chaque auteur des positions définies.
Scope and Suction: Hysteroscopic-guided Suction Evacuation of Cesarean Scar Pregnancy – A Safe and Efficacious Treatment for Selected Patients
Authors: Hameed* Mohamed Siraj Shahul , Wright Ann , Chern Bernard Su Min 
Published: May 2023

Objectives:
This study aimed to evaluate hysteroscopic-guided suction evacuation for the treatment of cesarean scar pregnancy (CSP).

Materials and Methods:
This was a retrospective analysis of CSP over 2 years. This study was conducted at KK Women’s and Children’s Hospital (KKH), Singapore, thirty-seven patients with a CSP. Hysteroscopic-guided suction evacuation to treat CSP used alone or in combination with laparoscopy depending on residual myometrial thickness (RMT) and future fertility requirements.

Results:
The majority of women (29) were diagnosed under 9-week gestation. Just over a third (13) had an RMT of more than 3 mm. Women with an RMT <3 mm had added laparoscopy. In total, 22 women had hysteroscopic-guided suction evacuation with 9 having it performed under laparoscopic guidance because the RMT was under 3 mm. The remaining patients underwent either laparoscopic repair (5 cases) or vaginal repair (1 case) done under laparoscopic guidance.

Conclusion:
Hysteroscopic-guided suction evacuation of CSP has the potential to become part of the routine management for uncomplicated cases of CSP in women with an RMT of greater than 3 mm who do not wish for future pregnancy. Its use, in combination with other minimally invasive techniques, can be extended to more complex cases where the RMT is <3 mm and future fertility is desired.

Published: May 2023

AbstractThe advents of information technologies have led to the creation of ever-larger datasets. Also known asbig data, these large datasets are characterized by its volume, variety, velocity, veracity, and value. More importantly, big data has the potential to expand traditional research capabilities, inform clinical practice based on real-world data, and improve the health system and service delivery. This review first identified the different sources of big data in ophthalmology, including electronic medical records, data registries, research consortia, administrative databases, and biobanks. Then, we provided an in-depth look at how big data analytics have been applied in ophthalmology for disease surveillance, and evaluation on disease associations, detection, management, and prognostication. Finally, we discussed the challenges involved in big data analytics, such as data suitability and quality, data security, and analytical methodologies.

Published: May 2023

Introducción: El siglo XXI está caracterizado por el avance tecnológico que ha experimentado la sociedad junto a los cambios sociales, económicos y medioambientales que conforman los desafiantes retos actuales. Estos han provocado que multitud de organizaciones se conviertan en agentes activos, despertando su interés por definir propósitos con impacto para la sociedad que necesita que las empresas tomen conciencia y se posicionen, desde un enfoque más humanista, ante cuestiones alarmantes. Uno de los escenarios en el que las organizaciones pueden desarrollar estrategias de comunicación que enriquezcan las relaciones con sus públicos y les permita defender sus propósitos, mediante la generación de contenidos, lo constituyen las redes sociales, herramientas clave para que las marcas se relacionen en la actualidad. Metodología: mediante metodología cuantitativa, a través de análisis de contenido, se analiza un corpus de mensajes emitidos en Twitter durante doce meses por diez marcas responsables, seleccionadas mediante el Monitor Empresarial de Reputación Corporativa. Resultados: se obtienen datos relevantes sobre los contenidos generados por estas marcas en sus perfiles de Twitter que indican que comunican principalmente poniendo el foco en el servicio que ofrecen y sus productos. Discusión: los resultados revelan que las marcas estudiadas generalmente toman una posición centrada en la propia empresa o en el producto. Conclusiones: aunque existe una tendencia por parte de las organizaciones a generar un beneficio social a través de sus actuaciones, esta investigación indica que el enfoque que estas empresas dan a su comunicación en Twitter no está orientado a las personas principalmente.

ABSTRACT. Magnesium, calcium, strontium, and barium complexes of uracil were prepared in a 2:1 ligand to metal ratio to investigate the ligational character of the uracil (Ura). The modes of chelation were explained depending on elemental analyses, FT. IR, 1H–NMR spectra as well as scanning electron microscopy. Uracil has two donation sites either through N(3) and C(2)=O, or through N(3) and C(4)=O with the molecular formulas [M(Ura)2(H2O)2]Cl2 where M = Mg(II), Ca(II), Sr(II) and Ba(II) . The morphological surface and particle size of uracil metal complexes were determined using SEM and TEM. The thermal behaviors of the complexes were studied by the TGA (DTG) technique. The data obtained agreed well the proposed structures and showed that the complexes were finally decomposed to the corresponding metal oxide. The thermodynamic parameters are calculated from the thermal analysis curves using the Coats–Redfern and Horowitz–Metzger methods. The negative values of deduced the ordered structures of the prepared complexes compared to their starting reactants. Antibacterial activity of ligands and complexes is evaluated with two types of bacteria Staphylococcus aureus (gram‐positive) and Escherichia coli (gram‐negative) by the agar-well diffusion technique using DMSO as a solvent.

Published: May 2023

The peculiarities of poor electricity generation and distribution which has resulted in high reliance on generators is implicated in the profile of Nigeria’s environmental pollution situation. Still, the consequences of the pervasive use of generators on health is yet to be optimally captured empirically, and macro-wise. Hence, this work was designed to examine correlations between generator use and some selected indices of- health. depreciator. Cross national, secondary data used were extracted from the 2018/19 Nigerian General Household Survey Panel Component (the 2018/19 GHS-Panel). Data on generator use and some selected indices of ill-health were subjected to descriptive and Spearman rank correlational analysis. Results indicated that generator is owned in 24.6% of Nigerian households. Only 55.4% of households have access to electricity; 11.3% and 12.4% of them primarily and secondarily rely on generators respectively. Male and female respondents reporting any health problem was 22.6% and 22.5% respectively, of which only 20.5% consulted a health practitioner. Respondents reporting drug purchase were 28.8%. Primary reliance on generator significantly and positively correlated with consultation with health practitioner (r = .879, p< 0.05), female health problems (r = .862, p< 0.05), drug purchase (r = .700, p< 0.05), cost of medication (r = .700, p< 0.05), male health problems (r = .667, p = 0.05) and cost of consultation (r = .667, p = 0.05). On the other hand, the use of generator as a secondary or other source of electricity is only significantly and positively related to cost of medication (r = .733, p< 0.05) and drug purchase (r = .717, p< 0.05). Generators are leading assets whose use is becoming a significant element of the Nigerian way of life. Marginal or zero reliance on generator for access to electricity would have kept the Nigerian people healthier than they are currently. Certainly, generator use is a vast sponsor of ill-health and a vicious depreciator of health in Nigeria.

Published: May 2023

The histoqualitative teratogenic effects of lamotrigine, a second-line anticonvulsant medicine, on the developing fetal brain structures when exposed in utero in a time- and dose-dependent manner remain unclear. On the other hand, lamotrigine is currently being widely prescribed as a first-line medicine in the management of maternal conditions like epileptic seizures and bipolar disorders, among others. The preferential use of lamotrigine is attributed to the considerations of its efficacy, tolerability, and minimal teratogenic effects on fetal organs like the brain, among others, though with insufficient supportive data. The aim of this study was therefore to evaluate the histo-quantitative effects of lamotrigine on the developing fetal brain structures when exposed in utero at varying dosages during different trimesters. The study adopted a post-test only experimental study design where a sample size of 30 sexually mature albino rat dams of the species (Rattus norvegicus) weighing between 250 + 30 grams was used. The rats were divided into two broad groups: 3 control rats and 27 dosage rats. The data collected was coded in Excel spreadsheets and analyzed in SPSS. Results were expressed as the mean + standard error of the mean (SEM), and values with a P < 0.05 were considered to be significant. Study findings depicted a reduction in brain weights, length, width, volumes, and volume densities of cortical and subcortical layers in a dose- and time-dependent manner. High lamotrigine dosages, especially during the first and second trimesters, were observed to be associated with significant mean reductions in the brain weights, length, width, volumes, and volume densities of the developing fetal brain structures. Therefore, further studies with higher primates closer to the human species as well as clinical trials are recommended to rule out the safety index of lamotrigine during pregnancy.

Purpose: To investigate the cytotoxic and alpha-amylase inhibitory (AAI) potential of methanol (MeOH) extract of T. minuta and its isolated metabolites.
Methods: Phytochemical investigation of MeOH extract of the aerial parts of T. minuta was accomplished using SiO2 and Rp-18 column chromatography (CC). The structures of the isolated metabolites were determined and verified based on various data, in addition to comparison with literature data. The metabolites were assessed for cytotoxic potential against HepG2, MCF-7, and HCT116 cell lines utilizing sulphur rhodamine B (SRB) assay. The in vitro AAI potential of the metabolites were also assayed, and the findings were confirmed using results from molecular docking studies.
Results: One thiophene (compound 1), one coumarin (compound 2), and three phenolic compounds (compounds 3-5) were isolated and characterized. Compound 1 exhibited a marked cytotoxic effect (IC50 values: 2.7 – 7.3 μM) on HepG2, MCF-7, and HCT116 cell lines, relative to doxorubicin (IC50 values: 0.18 - 0.60 μM), whereas compound 2 had a moderate cytotoxic effect on MCF-7 (IC50 17.7 μM). Besides, compounds 4 and 5 produced potent AAI effects, with IC50 values of 12.3 and 9.2 μM, respectively, and 91.8 and 94.7 % inhibition, respectively), when compared to acarbose (94.7 % inhibition and IC50 of 7.1 μM). Interestingly, the in vitro AAI and in silico results were in agreement with each other. Compounds 5 and 4 had more negative docking scores (-13.655 and -12.135 kcal/mol, respectively) than the native inhibitors, myricetin (-12.155 kcal/mol) and acarbose (-15.105 kcal/mol).
Conclusion: These results suggest that T. minuta is a valuable source of anti-diabetic and cytotoxic metabolites. However, there is a need to validate these results through additional in vivo and in vitro investigations.
