Authors: Vani Ade Teti , Putri Amalia Rahma , Abdullah Dessy Abdullah , Dewi Nadia Purnama , Triansyah Irwan
Published: March 2024

Aloin has many benefits potential as a medicine. However, it is necessary to carry out toxicity tests on experimental animals as a pre-screening test. Toxic effect parameters were seen from changes in body weight, tremors, convulsions, salivation, weakness, walking backward, walking on the stomach, death, and levels of SGOT and SGPT in experimental animals. This study aims to evaluate the in vivo acute aloin toxicity test results in mice (Mus Musculus) regarding potential toxic symptoms and animal death. A sample of 27 mice were separated into three groups for this investigation: the control group, the treatment group I at a dose of 2500 µg/kg BW, and the treatment group II at an amount of 5000 µg/kg BW, and 5 mice in the preliminary test. This study employed a laboratory experimental test method using a pre-post control group design study. Based on observations of experimental animals, it concluded neither the preliminary test nor the toxicity test revealed any toxic signs. Neither the initial test nor the toxicity test resulted in any observed animal fatalities. Before and after aloin administration, changes in body weight were significantly different. Treatment group II, treatment group I, and the control group's SGOT levels were classified from highest to lowest, with subsequent values of 22.4 U/L, 21.9 U/L, and 19.9 U/L. The highest value of 35.7 U/L, 32.1 U/L, and 26.2 U/L in the treatment groups II, I, and the control group was used to rank the SGPT levels. There were no toxic symptoms and no mortality in experimental animals, so it can be concluded that aloin did not cause harmful effects in mice, so it was categorized as a pseudo-lethal dose.

Authors: Shintaro Margareta , Bhirawa Sigit Wisnu Setya
Published: March 2024

Technological developments result in innovations in financial services called financial technology (fintech). The result of fintech development is the existence of QRIS (Quick Response Code Indonesian Standard) as an easy and practical digital payment system. QRIS attracts the attention of young people, namely students, to switch from cash to non-cash payments with QRIS. The problem in this study is how students prefer to use QRIS as a digital payment tool? is the seller involved in students' preferences in using QRIS as a digital payment tool? To answer this problem, researchers used a qualitative approach by collecting data through interviews with three types of informants, namely sellers, students who make cash payments, and students who make cash payments, and students who make payments with QRIS. The result of this study is that students' preferences in using QRIS depend on ingrained payment habits in the canteen. However, even so, the preference for QRIS convenience can support the efficiency of buying and selling transactions in canteens.

Published: March 2024

This research work investigated the potentials of unmodified Palm Kernel Fibers and its modified forms for the adsorption of Indigo blue dye from aqueous solutions using batch adsorption procedures. Characterization of the fibers were done with the scanning electron microscopy (SEM) and FTIR. Adsorption result showed that maximum uptake of 38.3, 31.0, 33.5 and 14.5 mg/g were respectively obtained for Bleached (BPKF), Acetylated (APKF), Mercerized (MPKF) and Unmodified Palm Kernel Fibers (UPKF) adsorbents at an optimum time of 3 hours. The sorption kinetic obeyed pseudo second order with the bleached adsorbent (BPKF) having the best fit, and at a certain time limit, intra-particle diffusion controlled the process. Data collected from effect of initial concentration experiments were better fit to the Freundlich isotherm. The result from the thermodynamics of the process showed an endothermic process. Increasing adsorbent dosages led to corresponding increase in the quantity of the indigo dye adsorbed by the different adsorbents. This work revealed the potentials of modified palm kernel fibers over the unmodified fiber for effective removal of Indigo blue dye from wastewater.

Les fantômes des esclaves nous murmurent à l’oreille : pas de futur sans reconnaissance du passé
Authors: Thermitus Tamara
Published: March 2024

Comme le disait James Baldwin, « L’histoire n’est pas le passé, c’est le présent. Nous portons notre histoire en nous. »  Ainsi, l’esclavage est inscrit dans l’ADN des corps noirs, il fait partie de leur histoire.

Ayant commencé sa vie d’artiste sous le nom de SAMO (Same Old Shit) patronyme illustrant les traumatismes du racisme marquant les âmes noires. Cet éternel jeune homme nous interpelle : comment parler du futur, lorsqu’on ne peut se débarrasser des fantômes du passé ?

En me fondant sur la Critical Race Theory, approche qui prend notamment en compte l’expérience du racisme anti-noir, j’analyserai certaines œuvres cruciales de Basquiat, porteuses de récits, pour appréhender la société. Ces œuvres nous parlent toujours en faisant de Basquiat un prophète.

Dans Water-Worshipper, (1984), il expose l’esclavage et rompt le silence en exposant les séquelles sociales écrasantes et implacables.

Et comment ignorer sa clairvoyance alors qu’il nous parle dans Defacment?(1983) de Michael Stewart qui est une illustration des traitements des corps noirs, cette œuvre nous parle aujourd’hui des noirs assassinés, de George Floyd. 

Ce que nous enseigne Basquiat : pas de futur sans reconnaissance du passé.

Published: March 2024

Investigating how, when, and what subjects learn during decision-making tasks requires tracking their choice strategies on a trial-by-trial basis. Here, we present a simple but effective probabilistic approach to tracking choice strategies at trial resolution using Bayesian evidence accumulation. We show this approach identifies both successful learning and the exploratory strategies used in decision tasks performed by humans, non-human primates, rats, and synthetic agents. Both when subjects learn and when rules change the exploratory strategies of win-stay and lose-shift, often considered complementary, are consistently used independently. Indeed, we find the use of lose-shift is strong evidence that subjects have latently learnt the salient features of a new rewarded rule. Our approach can be extended to any discrete choice strategy, and its low computational cost is ideally suited for real-time analysis and closed-loop control.
Comparative Brain-Wide Mapping of Ketamine and Isoflurane-Activated Nuclei and Functional Networks
Authors: Hu Yue , Du Wenjie , Qi Jiangtao , Luo Huoqing , Zhang Zhao , Luo Mengqiang , Wang Yingwei
Published: March 2024

Ketamine (KET) and isoflurane (ISO) are two widely used general anesthetics, yet their distinct and shared neurophysiological mechanisms remain elusive. In this study, we conducted a comparative analysis of the effects of KET and ISO on c-Fos expression across the brain, utilizing hierarchical clustering and c-Fos-based functional network analysis to evaluate the responses of individual brain regions to each anesthetic. Our findings reveal that KET activates a wide range of brain regions, notably in the cortical and subcortical nuclei involved in sensory, motor, emotional, and reward processing, with the temporal association areas (TEa) as a strong hub, suggesting a top-down mechanism affecting consciousness by primarily targeting higher-order cortical networks. In contrast, ISO predominantly influences brain regions in the hypothalamus, impacting neuroendocrine control, autonomic function, and homeostasis, with the locus coeruleus (LC) as a connector hub, indicating a bottom-up mechanism in anesthetic-induced unconsciousness. KET and ISO both activate brain areas involved in sensory processing, memory and cognition, reward and motivation, as well as autonomic and homeostatic control, highlighting their shared effects on various neural pathways. In conclusion, our results highlight the distinct but overlapping effects of KET and ISO, enriching our understanding of the mechanisms underlying general anesthesia.

Telomeres are crucial for cancer progression. Immune signalling in the tumour microenvironment has been shown to be very important in cancer prognosis. However, the mechanisms by which telomeres might affect tumour immune response remain poorly understood. Here, we observed that interleukin-1 signalling is telomere-length dependent in cancer cells. Mechanistically, non-telomeric TRF2 (telomeric repeat binding factor 2) binding at the IL-1-receptor type-1 (IL1R1) promoter was found to be affected by telomere length. Enhanced TRF2 binding at the IL1R1 promoter in cells with short telomeres directly recruited the histone-acetyl-transferase (HAT) p300, and consequent H3K27 acetylation activated IL1R1. This altered NF-kappa B signalling and affected downstream cytokines like IL6, IL8, and TNF. Further, IL1R1 expression was telomere-sensitive in triple-negative breast cancer (TNBC) clinical samples. Infiltration of tumour-associated macrophages (TAM) was also sensitive to the length of tumour cell telomeres and highly correlated with IL1R1 expression. The use of both IL1 Receptor antagonist (IL1RA) and IL1R1 targeting ligands could abrogate M2 macrophage infiltration in TNBC tumour organoids. In summary, using TNBC cancer tissue (>90 patients), tumour-derived organoids, cancer cells, and xenograft tumours with either long or short telomeres, we uncovered a heretofore undeciphered function of telomeres in modulating IL1 signalling and tumour immunity.

Published: March 2024

The wound healing process is an intricate biological phenomenon that requires various crucial components, including repair cells, proteins, and biological factors. The process of wound healing can be categorized into three interrelated stages: the stage of inflammation, proliferation, and remodeling. Any interruptions during this process can lead to wound healing that deviates from the typical progression. It is crucial to highlight that growth factors have a profoundly influential effect in this particular situation. This study conducts a thorough and analytical literature review to investigate the essential role of growth factors (TGF-β, PDGF, KGF, FGF, Pro Collagen, and VEGF) in wound healing. This study examines the biochemical and molecular mechanisms via which these growth factors impact the wound healing process, including the inflammation, proliferation, and remodeling phases, by analyzing current and authoritative scientific literature. This paper precisely outlines the role of these variables, including the role of the stem cell secretome enriched with growth factors such as TGF-β, PDGF, KGF, FGF, Pro Collagen, VEGF, and exogenous factors, as previously discussed. It explores their impact on tissue regeneration, angiogenesis, and extracellular matrix formation, essential components of the wound healing process. The main objective of this study is to provide a comprehensive summary of the latest research findings, which includes an in-depth analysis of the contributions of stem cell secretomes to wound healing. The findings provide useful insights into potential growth factor-based treatment approaches, highlighting how the components of the stem cell secretome can be leveraged to enhance the wound healing process.

Published: March 2024

In a field experiment conducted at Girija Prasad Koirala College of Agriculture and Research Center, Morang, Nepal, spanning from April to August 2022, the study aimed to assess the yield and biomass production of various okra (Abelmoschus esculentus L.) varieties, including Arka Anamika, Chandani, Chiranjeevi F1, F1 Glory, Gunjan, JK1666, OH-940, Punjab Selection, R35 Selection, and Swastik-2. Results unveiled significant variability among the varieties, with F1 Glory (0.91 Kg/m2) and Punjab Selection (0.96 Kg/m2) emerging as top performers in average yield per m2. Conversely, Arka Anamika, Gunjan, and JK1666 exhibited the lowest yields. Notably, Punjab Selection (4.17 Kg/m2), OH-940 (4.28 Kg/m2), and Swastik-2 (3.86 Kg/m2) showed the highest fresh biomass, while Gunjan had the lowest biomass. F1 Glory demonstrated the highest harvest index (1.14), followed by Chandani and Punjab Selection (both 0.88). These findings underscore the significant impact of varietal selection on okra productivity, highlighting the potential of Punjab Selection and F1 Glory for further exploration in vegetable cultivation and biomass production. The study underscores the importance of varietal selection in enhancing okra productivity and biomass production. Farmers should consider planting high-yielding varieties such as Punjab Selection and F1 Glory to maximize their yields and biomass. Additionally, further research is needed to explore optimal cultivation practices and management techniques tailored to these high-performing varieties. This study provides actionable recommendations for farmers to improve okra cultivation practices, ultimately enhancing agricultural productivity in Nepal and comparable agro-ecological conditions.

Published: March 2024

The use of ultrasound was found to be a very suitable and effective method for the degradation of hazardous dyestuffs. The degradation of dye molecules in aqueous media in the presence of various additives by ultrasonic irradiation was investigated in order to clarify the degradation mechanism. In this investigation, Methylene Blue (MB) has been used as a representative of azo dye and inorganic salts like NaCl and Na2SO4 were used as additives. Besides degradation in presence of CCl4 and H2O2 solutions were observed. ZnO nanoparticle was also used for the investigation of degradation. The volume of all solutions was 100ml containing 25mg/L of MB. The sonication of dye molecules were conducted for 0, 5, 15, 25 minutes. The degradation mechanism was discussed in details adopting UV- visible spectra. From the experiments it is clear that the acidic condition is favorable for dye degradation. Evaluating the results we have also found that all additives aided the degradation comparatively higher or lower the extent depending on their used amount in solution. So, it is a clear indication that azo dyes from waste water can be efficiently removed by using sonochemical irradiation method under acidic condition

Aims: The American Cancer Society,s estimates for brain and spinal cord tumors in the United States for 2023, include both adults and children,25,400 malignant tumors will be diagnosed. The objective of this study was to analyze the epidemiological profile, risk factors for complications and death in the in-hospital postoperative period, in addition to describing the histological type of intracranial tumors most frequently operated on in a private Brazilian institution.

Study Design: Retrospective cohort study.

Place and Duration of Study: Biocor Instituto/Rede D’Or, from 2018 to 2021

Methodology: Data were collected from the medical records of patients who underwent surgery for intracranial tumors. The variables analyzed in this study were demographic characteristics (age, sex, and comorbidities), histological types of primary and secondary neoplasms, anatomical location of the lesions, neurological deficits at admission and post-surgical treatment (at discharge), whether the surgery was urgent or elective, whether it was a reoperation, and whether there were deaths or complications during hospitalization.

Results: Of 242 patients, 11 patients were excluded, and 231 patients were included in the analysis. The most common histological type was meningioma, accounting for 28% of cases. The histological type most associated with the risk of death was hemangioblastoma; however, it was also the histological type that presented the lowest incidence of cases. 39 patients (17%) had some complication in the in-hospital postoperative period, and 14 patients (6%) died.

Conclusions: Meningiomas constituted the majority of cases, accounting for 28% of the sample. The rate of complications and mortality was higher when compared to data from the international literature because this series analyzed brain metastases together with the excision of primary tumors. Concerning in-hospital deaths, hemangioblastoma emerged as the histological type most associated with the risk of death. It is noteworthy, however, that hemangioblastoma also exhibited the lowest incidence among the various histological types.

The Position of Children's Characters in Children's Animation Postcolonialism Studies
Authors: Zahrok Siti , Isnah Encik Savira , Marsudi Marsudi , Hendrajati Enie , Subali Edy , Wahyudin Wahyudin
Published: March 2024

Children's literature has now begun to shift to digital media, known as children’s animation. Instead of children's literature being created for children, these works are written, edited and distributed by adults. This shows that adults (parents) have full power over the work that children will consume. Colonialism theory then questions what it means to write for children. This research appears with the real assumption of where the child is positioned in children’s cyber literature. The postcolonial approach is used to verify this assumption. The results show that children are treated as objects, a means to endure real problems faced by adults. It appears that writing for children in addition to exploring is also stuffing and imposing the will for the needs of adults: guiding children, training children through the process of reaching civilization which is again the power of adults to define it.
Benzene Purity Improvement and Feed Amount Reduction on Benzene Production
Authors: Owena Devina Neala Arva , Loeharja Bruce Wills Steadman , Hardani Halilintar , Cahyaningrum Herda
Published: March 2024

Global demand for benzene is expected to rise significantly. Previous research focused on extracting toluene from water, but a proposed shift towards preventive measures includes recycling toluene to avoid pollution and enhance benzene production. Emphasis on addressing separation ratios and material balance is crucial for successful simulations. Proposed innovations involve added splitters and shortcut columns for enhanced purity. Benzene production could be gained through the process of hydrodealkylation with some modifications. It shows the significant difference of the purity of benzene produced with the use of splitter and shortcut column compared to not using splitter and shortcut column. The recycling process effects the mass flow of the compound which picture the capability of a process to scale up. Through recycling the toluene, it also happens to cut or push the sum of the feed which leads the process to be more economical. Based on the modification of the benzene production it is resulted that the mass flow rate of the benzene production is significantly increased from 38.6 kg/h to 430.72 kg/h which gives possibility of the production to be higher in one go. Recycling toluene and hydrogen will also help the effectivity and efficiency of the process by its quality and specifically its quantity of the fresh feed. The modification also affects the purities of the benzene from 70.72% to 99.95%. Therefore, by doing the modification it will produce greater number of benzene with its high purities.

To understand the self‐assembly process of the transition metal (TM) nanoclusters and nanowires self‐synthesized by hydroquinone (HQ) and calix[4]hydroquinone (CHQ) by electrochemical redox processes, we have investigated the binding sites of HQ for the transition‐metal cations TMn+=Ag+, Au+, Pd2+, Pt2+, and Hg2+ and those of quinone (Q) for the reduced neutral metals TM0, using ab initio calculations. For comparison, TM0–HQ and TMn+–Q interactions, as well as the cases for Na+ and Cu+ (which do not take part in self‐synthesis by CHQ) are also included. In general, TM–ligand coordination is controlled by symmetry constraints imposed on the respective orbital interactions. Calculations predict that, due to synergetic interactions, silver and gold are very efficient metals for one‐dimensional (1D) nanowire formation in the self‐assembly process, platinum and mercury favor both nanowire/nanorod and thin film formation, while palladium favors two‐dimensional (2D) thin film formation.
