Citizen Engagement in Print Media
Authors: Tjiramanga Alexandra 
Published: December 2023

This paper explores the content and communication acts of text messages in the form of SMSes written by Namibian citizens and published daily under “What you’re Saying!” in The Namibian. Its main aim is to provide insights into the realities of the population at grassroot-level, which are brought to light via the medium of the newspaper. Using the theoretical framework of Medium theory and theory of Cultural Hegemony, this paper argues that citizen engagement via SMS discloses how public communication contributes to press freedom, problem solving and nation-building in Namibia. The “What you’re saying” platform enables alternative and activist citizen participation in the discussion of their choice. This study used 286 SMSes to identify areas of concern of Namibian citizens. The study’s objectives were to presents issues, such as eduation, health, or service delivery directed to entities in the public and private sector, Further objectives include sub-themes, and communication acts, such as criticism, information-giving, complaint, suggestion, question, request, review and praise. The analysis discusses frequency of keywords in relation to the themes and sub-themes used. The findings are related to services and governance. Another feedback mechanism might be required to show responses to legitimate concerns.

PENGARUH ICE BREAKING TERHADAP HASIL BELAJAR SISWA PADA POKOK BAHASAN FPB DAN KPK KELAS V SDN KRAMAT 01 BANGKALAN
Authors: Alfiyatin Yuliana 
Published: December 2023

Berdasarkan hasil observasi di SDN Kramat 01 Bangkalan, tepatnya di kelas V menunjukkan bahwa suasana pembelajaran yang monoton sebab Guru menerapkan pembelajaran konvensional yaitu menjelaskan, memberi contoh dan memberi tugas serta pembahasan dalam proses pembelajaran. Hal tersebut memunculkan rasa bosan dan kurangnya rasa semangat pada sebagian siswa sehingga banyak siswa yang kurang memperhatikan guru saat menjelaskan materi pembelajaran, akibatnya hasil belajar belum mampu untuk dicapai. Dibuktikan dengan hasil belajaran siswa banyak yang mendapatkan nilai di bawah KKM (Kriteria kelulusan minimal) yaitu 70, serta secara klasikal kurang dari 80% siswa secara klasikal yang mendapat nilai di atas KKM.
Peneliti ingin menerapkan inovasi pembelajaran yang dapat membantu siswa dalam meningkatkan semangat siswa dalam belajar dan hasil belajarnya. Salah satu alternatifnya yang dapat dikembangkan untuk membantu permasalahan tersebut adalah melalui permainan ice breaking diharapkan siswa menjadi semangat dalam belajar dan menjaga konsentrasi dan perhatian dalam melakukan proses pembelajaran menjadi lebih baik dan siswa dapat memahami materi yang disampaikan oleh guru.

Foxa2 attenuates steatosis and inhibits the NF-κB/IKK signaling pathway in nonalcoholic fatty liver disease
Authors: Yang Li , Ma Qiang , Chen Jiayu , Kong Xiangcai , Yu Xiaohui , Wang Wei 
Published: December 2023

Objective
Forkhead box a2 (Foxa2) is proven to be an insulin-sensitive transcriptional regulator and affects hepatic steatosis. This study aims to investigate the mechanism by which Foxa2 affects nonalcoholic fatty liver disease (NAFLD).

Methods
Animal and cellular models of NAFLD were constructed using high-fat diet (HFD) feeding and oleic acid (OA) stimulation, respectively. NAFLD mice received tail vein injections of either an overexpressing negative control (oe-NC) or Foxa2 (oe-Foxa2) for four weeks. HepG2 cells were transfected with oe-NC and oe-Foxa2 for 48 h before OA stimulation. Histological changes and lipid accumulation were assessed using hematoxylin-eosin staining and oil red O staining, respectively. Expression of Foxa2, NF-κB/IKK pathway proteins, lipid synthesis proteins, and fatty acid β-oxidation protein in HFD mice and OA-induced HepG2 cells was detected using western blot.

Results
Foxa2 expression was downregulated in HFD mice and OA-induced HepG2 cells. Foxa2 overexpression attenuated lipid accumulation and liver injury, and reduced the levels of aspartate aminotransferase, alanine aminotransferase, total cholesterol, or triglyceride in HFD mice and OA-induced HepG2 cells. Moreover, Foxa2 overexpression decreased the expression of lipid synthesis proteins and increased fatty acid β-oxidation protein expression in the liver tissues. Furthermore, overexpression of Foxa2 downregulated the expression of p-NF-κB/NF-κB and p-IKK/IKK in OA-induced HepG2 cells. Additionally, lipopolysaccharide (NF-κB/IKK pathway activator) administration reversed the downregulation of lipid synthesis proteins and the upregulation of fatty acid β-oxidation protein.

Conclusion
Foxa2 expression is downregulated in NAFLD. Foxa2 ameliorated hepatic steatosis and inhibited the activation of the NF-κB/IKK signaling pathway.

Macaranga hurifolia (ZG02), Mallotus oppositifolius (ZG04), and Mareya micrantha (ZG08) are ethnomedicinal plants belong to Euphorbiaceae family Which are frequently used in treating various diseases in Ivory Coast. The aim of this study is to determine the phytochemical composition and safety level of these three plants.
Phytochemical assays were conducted using tubes following standard methods. Acute toxicity was assessed according to OECD 423 guidelinesThe rats were divided into fifteen groups of three rats each, 4 control groups,4ZG02 groups, 4 ZG04 groups, and 3 ZG08 groups).
Results of phytochemical analysis revealed that ZG02 contains polyphenols, flavonoids, alkaloids, gallotannins, and saponins. ZG04 contains polyphenols, flavonoids, catechin tannins, saponins, as well as sterols and terpenoids.While ZG08 contains polyphenols, flavonoids, gallotannins, catechin tannins, saponins, as well as sterols and terpenoids.
Regarding acute toxicity, administration of the aqueous extracts for the determination of acute toxicity of ZG02 and ZG04, did not produce any mortality in the rats for dosages of up to 2000 mg/kg. Thus, the LD50 (lethal dose for 50% of the population) of ZG02 and ZG04 is greater than 2000 mg/kg of body weight. However, the treatment of ZG08 at 300 mg/kg of body weight, caused a modification in the behavior of the test animals, while the treatment at 2000 mg/kg of body weight resulted in the death of all 3 tested ras. The LD50 of ZG08 is equal to 500 mg/kg of body weight.
In conclusion, the presence of rich active phytochemical, justifying the traditional uses of the plant. ZG02 and ZG04 show no oral toxicity, while ZG08 is toxic through this route
The relative size of the calcaneal tuber reflects heel strike plantigrady in African apes and humans
Authors: Prang Thomas C. 
Published: December 2023

AbstractObjectivesThe positional repertoire of the human‐chimpanzee last common ancestor is critical for reconstructing the evolution of bipedalism. African apes and humans share a heel strike plantigrade foot posture associated with terrestriality. Previous research has established that modern humans have a relatively large and intrinsically robust calcaneal tuber equipped to withstand heel strike forces associated with bipedal walking and running. However, it is unclear whether African apes have a relatively larger calcaneal tuber than non‐heel‐striking primates, and how this trait might have evolved among anthropoids. Here, I test the hypothesis that heel‐striking primates have a relatively larger calcaneal tuber than non‐heel‐striking primates.MethodsThe comparative sample includes 331 individuals and 53 taxa representing hominoids, cercopithecoids, and platyrrhines. Evolutionary modeling was used to test for the effect of foot posture on the relative size of the calcaneal tuber in a phylogenetic framework that accounts for adaptation and inertia. Bayesian evolutionary modeling was used to identify selective regime shifts in the relative size of the calcaneal tuber among anthropoids.ResultsThe best fitting evolutionary model was a Brownian motion model with regime‐dependent trends characterized by relatively large calcaneal tubers among African apes and humans. Evolutionary modeling provided support for an evolutionary shift toward a larger calcaneal tuber at the base of the African ape and human clade.ConclusionsThe results of this study support the view that African apes and humans share derived traits related to heel strike plantigrady, which implies that humans evolved from a semi‐terrestrial quadrupedal ancestor.
Tailored rheological development in OPC systems by controlled ettringite precipitation and its effect on compressive strength

Published: December 2023

AbstractThe control of rheological properties is gaining in importance to meet the special requirements for cementitious materials in novel technologies such as 3D‐printing. A deeper understanding of the underlying mechanisms of cement hydration is necessary to customize the mix design to the specific application.The hydration of OPC is mainly characterized by the silicate and aluminate reaction. The aluminate reaction is especially relevant for the early rheological development, whereas the formation of C‐S‐H (silicate reaction) is responsible for the later hardening of the hydrating paste.A hydration control agent is used to delay the initial aluminate reaction to a defined point in time. When no additional mixing occurs during this period of rapid ettringite precipitation, the cement paste stiffens to a solid cement stone. However, when the sample is mixed during this period, the workability of the paste is retained. The rheological changes can be correlated directly to the magnitude of ettringite formation. Additionally, the compressive strength and pore size distribution of all systems (reference, HCA, HCA with additional mixing) are investigated to analyze the long‐term properties. These results predict future customized mix designs in various application fields.

Published: December 2023

AbstractBackgroundDiabetes mellitus (DM)‐associated hyperinflammatory host response significantly provokes periodontal tissue destruction. In this context, the support of nonsurgical periodontal therapy in diabetics with host modulation agents is a current field of study. This clinical study aims to investigate the clinical efficacy of melatonin supplementation and discuss its possible biological mechanisms in nonsurgical periodontal treatment in patients with DM and periodontitis through some fundamental markers.MethodsIn this randomized controlled and single‐blind study, 27 of 55 diabetic patients with periodontitis (stage III/IV and grade C) underwent full‐mouth scaling and root planing (fmSRP) alone and 28 patients underwent melatonin administration (6 mg daily, 30 days) in addition to fmSRP (full‐mouth scaling and root planing plus melatonin, fmSRP‐mel). The potential therapeutic contribution of melatonin was evaluated clinically and biochemically (gingival crevicular fluid RANKL, OPG, MMP‐8, and serum IL‐1β levels) at 3rd and 6th months.ResultsMelatonin (tablet, 6 mg daily, 30 days) did not cause any local or systemic side effects. fmSRP alone resulted in significant reduction in serum IL‐1β levels, pocket depths, gingival inflammation, and gingival crevicular fluid RANKL and MMP‐8 levels (p < 0.05). Moreover, melatonin supplementation resulted in a more significant decrease in bleeding and pocket depth scores at probing, especially at 3 months (p < 0.05). Furthermore, RANKL and MMP‐8 levels were significantly lower at 3 months and IL‐1β levels at 6 months compared to the control group (p < 0.05). However, OPG levels were not affected significantly by the treatments (p > 0.05).ConclusionMelatonin, as a host modulation agent, significantly increases the clinical efficacy of fmSRP. The reduction in periodontal inflammation and pocket depths may be a result of marked suppression of RANKL‐associated osteoclastogenesis and extracellular matrix damage by melatonin.
Model of mesopelagic fish predation on eggs and larvae shows benefits of tuna spawning under full moon
Authors: Ottmann Daniel , Langbehn Tom J. , Reglero Patricia , Alvarez‐Berastegui Diego , Fiksen Øyvind 
Published: December 2023

AbstractMost mesopelagic fish are small planktivores that migrate up at nightfall to feed in the safety of darkness and descend to depth at dawn to escape visual predators. However, the trophic roles can reverse since mesopelagic fishes also predate eggs and larvae of their predators. We use the Atlantic bluefin tuna as a model species to test the hypothesis that fishes in the open ocean synchronize spawning to moon‐lit nights (when mesopelagic fishes avoid near‐surface waters) to increase offspring fitness. Our analysis over two decades of field observations shows that tuna spawn most intensively the week before full moon. This fits predictions from a mechanistic model where spawning around full moon increases offspring fitness by two orders of magnitude due to low predation from mesopelagic fishes. Circalunar patterns of food availability can also favor fitness of offspring spawned the days before full moon. Our findings suggest that mesopelagic fishes may have an important impact on pelagic fish through predation of early life stages and cause an evolutionary drive to synchronize spawning to the lunar cycle.

The analysis of the nitrogen (N) isotopic composition of organic matter bound to fossil biomineral structures (BB‐δ15N) using the oxidation–denitrifier (O–D) method provides a novel tool to study past changes in N cycling processes.MethodsWe report a set of methodological improvements to the O–D method, including (a) a method for sealing the reaction vials in which the oxidation of organic N to NO3− takes place, (b) a recipe for bypassing the pH adjustment step before the bacterial conversion of NO3− to N2O, and (c) a method for storing recrystallized dipotassium peroxodisulfate (K2S2O8) under Ar atmosphere.ResultsThe new sealing method eliminates the occasional contamination and vial breakage that occurred previously while increasing sample throughput. The protocol for bypassing pH adjustment does not affect BB‐δ15N, and it significantly reduces the processing time. Storage of K2S2O8 reagent under Ar atmosphere produces stable oxidation blanks over more than 3.5 years. We report analytical blanks, accuracy, and precision for this methodology from eight users over the course of ~3.5 years of analyses at the Max Planck Institute for Chemistry. Our method produces analytical blanks characterized by low N content (0.30 ± 0.13 nmol N, 1σ, n = 195) and stable δ15N (−2.20 ± 3.13‰, n = 195). The analysis of reference amino acid standards USGS 40 and USGS 65 indicates an overall accuracy of −0.23 ± 0.35‰ (1σ, n = 891). The analysis of in‐house fossil standards gives similar analytical precision (1σ) across a range of BB‐δ15N values and biominerals: zooxanthellate coral standard PO‐1 (6.08 ± 0.21‰, n = 267), azooxanthellate coral standard LO‐1 (10.20 ± 0.28‰, n = 258), foraminifera standard MF‐1 (5.92 ± 0.28‰, n = 243), and tooth enamel AG‐Lox (4.06 ± 0.49‰, n = 78).ConclusionsThe methodological improvements significantly increase sample throughput without compromising analytical precision or accuracy down to 1 nmol of N.

Published: December 2023

AbstractThe interaction of education and digital technology today is one of the key characteristics of development. Many industrialized nations place a high value on digital learning practices and have created several national strategic plans to encourage and support the use of digital practices in education. In its reform and development of education, Eritrea has also made the strategic decision to assist educational modernization using a clear digital policy. Eritrea has made significant advancements in the creation of technology infrastructure, the use of digital resources, innovative teaching methods, and technology-supported educational management to date. However, there are still issues with execution brought on by teachers' preparation, public spending, and human resources. The study collected useful information from n = 141 active student-teachers participating in post-graduate diploma (PGD) practice at Asmara College of Education utilizing both qualitative and quantitative research methodologies. Results have been reported using special and original quotes together with both descriptive and inferential statistics. The study's conclusions show that teachers' enthusiasm for using ICT in the classroom will have a favorable effect on their ability to teach, assisting them in becoming aware of the modernized world and adjusting to its expectations. The knowledge of the teachers has a big impact on digital activities. Additionally, the research has revealed that Eritrean school instructors have little knowledge of using ICT in teaching and learning to improve student performance. The perception of teachers' preparation for digital competency is positive, even though a noteworthy problem is being highlighted that prevents teaching and learning from succeeding. They have a very high and favorable opinion of how the use of technology has affected their ability to teach.

Abstract

Background:
Social Network Analysis is a method of analyzing coauthorship networks or relationships through graph theory. Institutional Development Award (IDeA) Networks for Clinical and Translational Research (IDeA-CTR) was designed to expand the capability for clinical and translational research to enhance National Institutes of Health funding.

Methods:
All publications from a cohort of clinical and translational scientists in Oklahoma were collected through a PubMed search for 2014 through 2021 in October 2022. For this study’s bibliometric portion, we pulled the citations from iCite in November of 2022.

Results:
There were 2,391 articles published in 1,019 journals. The number of papers published by year increased from 56 in 2014 to 448 in 2021. The network had an average of 6.4 authors per paper, with this increasing by year from 5.3 in 2014 to 6.9 in 2021. The average journal impact factor for the overall network was 7.19, with a range from 0.08 to 202.73. The Oklahoma Shared Clinical and Translational Resources (OSCTR) network is a small world network with relatively weak ties.

Conclusions:
This study provides an overview of coauthorship in an IDeA-CTR collaboration. We show the growth and structure of coauthorship in OSCTR, highlighting the importance of understanding and fostering collaboration within research networks.
