Published: March 2023

Aplodinotus grunniens represent a crucial artisanal fishery in the Usumacinta River’s middle basin that generates food and a subsistence economy. This study aimed to create a model that best describes growth for A. grunniens and provides information on the growth of this poorly known pecies from the Usumacinta River. Data collection was carried out over one year through monthly sampling. A total of 447 specimens were collected from January to December 2017. Von Bertalanffy’s growth constants were calculated by separate sexes using linear fit and the non-linear Levenberg-Marquardt method. Hotelling’s T-squared test showed that growth was significantly faster in females than males. The estimated age at first maturity was two years in males and three in females. Considering the age reported for A. grunniens in other studies, the age determined in this study indicates that the population could be overexploited. Larger fish are more vulnerable to fishing pressure, mainly during their highest reproductive activity when they aggregate for spawning. More research is needed to evaluate the population status, catch per unit effort, distribution, and abundance of adults, juveniles, and larvae.

ASTRAK : Pertumbuhan listrik yang semakin pesat dan terus menerus ini membuat ketersediaan listrik harus terus meningkat. Apalagi dengan program 35.000 MW yang dicanangkan oleh pemerintah Republik Indonesia yang masih dalam proses. Namun, pertumbuhan beban listrik yang terus menerus mengakibatkan peningkatan pasokan sumber daya alam (NR) bahan bakar dan daya yang digunakan sebagai daya untuk konsumsi generator itu sendiri. Pada penelitian ini dilakukan analisis terutama pada konsumsi daya pembangkit yang cukup besar pada saat standby mode yang dilakukan pada PLTDG. PT Indonesia Power Pesanggaran. Oleh karena itu, perlu dilakukan peremajaan atau penggantian peralatan listrik yang digunakan untuk menghemat konsumsi energi. Salah satu peralatan yang mengkonsumsi daya dalam jumlah besar saat unit dalam keadaan standby adalah Electric Preheater. Dengan adanya program ini dimaksudkan untuk memperoleh penghematan energi listrik dari konsumsi listrik Preheater yang seharusnya 108 kWatt menjadi 0 Watt dengan menggunakan Thermal Preheater, sehingga terjadi penghematan konsumsi energi listrik sesuai yang diharapkan, dan mampu mengurangi konsumsi energi di sektor pembangkit sesuai dengan tujuan PROPER KLHK (Kementerian Lingkungan Hidup dan Kehutanan) dan berkontribusi pada SDG'S (Sustainable Development Goals) poin 7 tentang energi bersih dan terjangkau.

Published: March 2023

Abstract
The quantification of plant secondary metabolites at levels higher than the population (i.e. community and ecosystem) requires the implementation of efficient, low-cost, and small-scale assays. We propose a modified protocol based on the Folin-Ciocalteu colorimetric assay that integrates the simultaneous quantitative determination of total phenols and total tannins from 40 µL of methanolic extract, and a modified aluminum chloride assay to quantify total flavonoids from 20 µL of methanolic extract. These miniaturized microplate colorimetric assays were tested and adjusted to work with as little as 50 mg of foliar tissue and to encompass the variation of secondary metabolite concentrations present in trees of 77 species, 58 genera, and 27 families from conserved and secondary tropical dry forest. At present, these new protocols are of great relevance to study ecological processes in highly diverse and strongly threatened ecosystems.

AbstractPurpose:To describe retina oxidative parameters and carnosine influence in diet-induced obesity model.Methods:Wistar rats were randomly divided into four groups: Standard diet (SD), high sugar-fat diet (HcD), standard diet + carnosine (SD+Carn), and high sugar-fat diet + carnosine (HcD+Car). Evaluation in animals included body weight, adiposity index, plasma glucose, total lipids, high density lipoprotein (HDL), and low-density lipoprotein (LDL), uric acid, creatinine, and triglycerides. The retinas were analyzed for markers of oxidative stress. Hydrogen peroxide production was assessed by oxidation of 2', 7'-dichlorodihydrofluorescein diacetate (DCFH-DA). The analysis of the antioxidant system included total glutathione (tGSH), total antioxidant capacity (TAC), protein carbonyl, and sulfhydryl type.Results:The hypercaloric diet induced higher body weight, adiposity index, glucose, and triglyceride. Carnosine supplementation influenced on plasma triglyceride. Absence of diet effect was verified in retina fluorescent derivative of oxidized DCFH-DA (DCF), TAC, GSH reduced levels and GSH:GSSG ratio. High retina TAC levels were found in rats treated with carnosine. Retina GSH reduced levels and GSH:GSSG ratio improved in carnosine-supplemented rats treated with high sugar-fat diet (vs.SD+Car). Diet was associated with increase in retina carbonyl content and decrease in sulphydryl levels. However, carnosine supplementation had no interference in both retina parameters from animals treated with high sugar-fat diet.Conclusion: The results suggest that the sugar- and fat-enriched diet fed the rats may trigger an imbalance in the retinal redox state and that carnosine may improve the oxidative parameters.

Published: March 2023

Abstract
Background
The COVID-19 pandemic caused dramatic upheaval in the lives of undergraduate students at colleges and universities. This study aimed to characterize the experience of a group of STEM-interested students and included 190 college youth who were part of a larger, 10-year longitudinal study of science college and career pathways. All participants completed a mentored science research program in high school. Over 78% of the participants were currently majoring in a STEM discipline (National Science Foundation, 2015); 80% identify as BIPOC. Participants completed surveys in Fall 2020 and Spring 2021; 26 were interviewed during Summer 2021. The survey consisted of closed and open-ended items about their experience in college during the pandemic, as well as a social network survey which asked participants to name individuals who had supported them.
Results
Students reported both challenges they experienced during the pandemic and resources upon which they drew. Challenges included online learning, opportunities for collaboration, and lack of support for career pathway planning. Second-year students were most likely to report significant challenges. Rates of switching majors into and out of STEM were comparable to previously published studies; however, we uncovered stories of students switching out of STEM due to pandemic circumstances. Students reported drawing upon their networks for guidance and most frequently named parents and friends as providers of support; however, they named faculty as individuals that provided multiple types of support.
Conclusions
The pandemic exacerbated inequitable circumstances that existed pre-pandemic; colleges and universities and individuals that comprise youth social networks can act to offer support to mitigate pandemic impacts, as well as improve business as usual.

Intelligent system simulation and data accuracy of physical fitness training for sports majors based on real-time status update of wearable Internet of Things
Authors: Yong Zhou 
Published: March 2023

Abstract
With the development of modern science and technology, sports training has begun to develop in the direction of new ideas, new technologies and new equipment. Wearable devices with wireless data transmission and real-time feedback functions are more and more widely used in sports training, providing a simpler and more scientific way to explore the biological significance of sports training. In this paper, the wearable Internet of Things is applied to the intelligent system simulation of physical training for sports majors. With the support of the Internet of Things technology, wearable devices can quickly capture the movement data of students' physical training, and quickly transmit these information to the intelligent system of physical training for sports majors, so that the system can be updated in real time. Wearable devices are high-tech products developed in the context of big data. The use of wearable devices to achieve sports training and data collection is only an external manifestation of sports scientific monitoring. The collection and statistics of the original sports data obtained through more scientific information processing technology is the focus of sports scientific monitoring. At present, the use of wearable devices in sports training also has some measurement errors, which affect the validity and credibility of data. Data processing is not systematic and perfect, and the compatibility and connectivity are low. Statistical analysis is a common way to analyze sports training data at home and abroad. This paper discusses the physical training data based on the status update of the wearable object network, and uses the optimized data processing method to improve the accuracy of the data.
Barriers and facilitators to oral hygiene for critically ill patients at a regional referral hospital in Uganda: A qualitative study
Authors: Lotuk Emmanuel , Mwebembezi Gerald , Najjuma Josephine N 
Published: March 2023

Abstract
Introduction: Critically ill patients may not take care of activities of daily living like oral care. Due to the complexity of care and need for close monitoring for critically ill patients, they are commonly admitted to high dependence units (HDU) or Intensive Care Unit (ICU) where oral health is expected to be provided by the bed side nurses. In Low and Middle-Income countries (LMIC) where there are low staffing levels, patient family (caregivers) are expected to help with some of the nursing procedures like oral care. We aimed to explore the barriers and facilitators to quality oral hygiene by caregivers for critically ill patients at a rural regional referral hospital in southwestern Uganda.
Methods: We conducted in-depth qualitative interviews with 9 purposively selected adult caregivers for patients who were critically ill admitted at emergency ward and intensive care units of Mbarara Regional Referral Hospital. Data was analyzed by thematic analysis.
Results: Themes identified were divided into barriers and facilitators. Barriers included lack of knowledge about oral hygiene for critically ill patients, lack of support from the nursing staff, directional training/teaching for oral hygiene, critically ill state of the patient, fear/discomfort, and limited resources for oral hygiene, the facilitators included training/teaching, availability of resources, patients’ previous quality of oral care, and family support.
Conclusion: Training/teaching patient family and provision of supplies for oral care may facilitate quality oral care for critically ill patients in resource limited settings like Uganda.

Abstract
Background: Deep inequalities in maternity care and outcomes for women from ethnic minority groups were present before the coronavirus pandemic. During the pandemic, rapid and heterogeneous changes were made to maternity services and care. It is not known what effect these changes have had on maternity outcomes and whether this effect differed across ethnic groups. Identification of changes which may reduce inequality is a national priority. The aim of this project was to identify changes in maternity care which reduced inequalities in maternal and perinatal outcomes during the period of rapid organisational change in the COVID-19 pandemic.
Methods: A Women’s Reference Group of public advisors guided the project. Analysis of Hospital Episode Statistics Admitted Patient Care data of 128 NHS Trusts in England identified “positive deviant” healthcare organisations that reduced inequalities in maternity outcomes. Maternal and perinatal composite adverse outcome indicators were used to compare outcomes between White and Minority ethnic groups, before and during the pandemic to identify “positive deviants”. Positive deviant Trusts were identified for qualitative interview, alongside comparators. Senior clinicians, heads of midwifery and representatives of women giving birth were interviewed. Reflexive thematic analysis was employed.
Results: We conducted 20 interviews from six positive deviant and four comparator Trusts. Positive deviants reported that necessary shifts in roles led to productive and novel use of expert staff; comparators reported senior staff ‘stepping in’ where needed and no benefits of this. They reported proactivity and quick reactions, increased team working, and rapid implementation of new ideas. Comparators found constant changes overwhelming, and no increase in team working. No specific differences in care processes were identified.
Conclusions: Proactivity, flexibility, staffing resource, and increased team working were associated with a reduction in ethnic inequalities in maternal and perinatal outcomes. Hence, harnessing these strengths of high-functioning units proves vital in reducing health inequalities.

Published: March 2023

AbstractMarine phytoplankton size-class structure affects ecological functions and shellfish culture. We use high-throughput sequencing and size-fractioned grading techniques to identify and analyze responses of phytoplankton differences in environmental variables at Donggang, northern Yellow Sea (high inorganic nitrogen (DIN)) and Changhai (low DIN) for 2021. The main environmental variables that correlate with differences in the proportional contributions of pico-, nano-, and microphytoplankton to the total phytoplankton community are inorganic phosphorus (DIP), nitrite to inorganic nitrogen ratio (NO2/dissolved inorganic nitrogen (DIN)), and ammonia nitrogen to inorganic nitrogen ratio (NH4/DIN), respectively. DIN, which contributes most to environmental differences, mainly positively correlates with changes in picophytoplankton biomass in high DIN waters. Nitrite (NO2) correlates mostly with changes in the proportional contribution of microphytoplankton in high DIN waters and nanophytoplankton in low DIN waters, and negatively correlates with changes in the biomass and proportional representation of microphytoplankton in low DIN waters. For near-shore phosphorus-limited waters, an increase in DIN may increase total microalgal biomass, but proportions of microphytoplankton may not increase; for high DIN waters, an increase in DIP may increase proportions of microphytoplankton, while for low DIN waters, an increase in DIP may preferentially increase proportions of picophytoplankton and nanophytoplankton. Picophytoplankton contributed little to the growth of two commercially cultured filter-feeding shellfish,Ruditapes philippinarumandMizuhopecten yessoensis.

Abstract
Floods are a major natural disaster that causes significant losses to life and property, particularly in flood-prone areas like the north-western region of Bangladesh. Accurate and timely assessment of flood impacts is crucial for effective flood management and decision-making by stakeholders. In this study, we employed geospatial and remote sensing techniques to assess the impact of the 2020 flood in Kurigram and Lalmonirhat districts. We utilized synthetic aperture radar (SAR) data from Sentinel-1 and the Google Earth Engine platform to generate near real-time flood inundation maps. We used an automatic threshold method to calculate inundated areas from the SAR data. For land use/land cover (LULC) analysis, we used the high resolution sentinel-2 image using machine learning algorithms like artificial neural network (ANN), random forest (RF) and support vector machine (SVM). The best LULC method was selected using six performance matrices like kappa, accuracy, and F1 score. Our results showed that the highest inundation occurred in July, with more than 600,000 people exposed to floods, which is about 17% of the total population. The ANN model outperformed other models for LULC mapping with the accuracy of 0.94. The LULC map generated from our machine learning algorithm showed high accuracy, enabling us to identify the most vulnerable areas for floods and prioritize flood management efforts. The croplands were the most affected areas, with 53.7% being inundated in July. Our study highlights the potential of SAR data and machine learning algorithms for near real-time flood monitoring and accurate LULC mapping, which are essential for reliable flood management. The use of remote sensing data and geospatial techniques can facilitate more efficient and effective decision-making in response to natural disasters like floods. Our findings can assist decision-makers in developing appropriate flood management strategies to minimize the impacts of floods on life, property, and agricultural production.

Abstract
Identifying genes whose expression is associated with schizophrenia (SCZ) risk by transcriptome-wide association studies (TWAS) facilitates downstream experimental studies. Here, we integrated multiple published datasets of TWAS (including FUSION, PrediXcan, summary-data-based Mendelian randomization (SMR), joint-tissue imputation approach with Mendelian randomization (MR-JTI)), gene coexpression, and differential gene expression analysis to prioritize SCZ candidate genes for functional study. Convergent evidence prioritized Propionyl-CoA Carboxylase Subunit Beta (PCCB), a nuclear-encoded mitochondrial gene, as an SCZ risk gene. However, the PCCB’s contribution to SCZ risk has not been investigated before. Using dual luciferase reporter assay, we identified that SCZ-associated SNP rs35874192, an eQTL SNP for PCCB, showed differential allelic effects on transcriptional activities. PCCB knockdown in human forebrain organoids (hFOs) followed by RNA-seq revealed dysregulation of genes enriched with multiple neuronal functions including gamma-aminobutyric acid (GABA)-ergic synapse, as well as genes dysregulated in postmortem brains of SCZ patients or in cerebral organoids derived from SCZ patients. The metabolomic and mitochondrial function analyses confirmed the deceased GABA levels resulted from reduced tricarboxylic acid cycle in PCCB knockdown hFOs. Multielectrode array recording analysis showed that PCCB knockdown in hFOs resulted into SCZ-related phenotypes including hyper-neuroactivities and decreased synchronization of neural network. In summary, this study utilized hFOs-based multi-omics data and revealed that PCCB downregulation may contribute to SCZ risk through regulating GABAergic system, highlighting the mitochondrial function in SCZ.
