Authors: Maroti Djiope Popadem
Published: November 2022

Northern Cameroon has been crossed for many decades by various ecological phenomena, including drought. This problem which has appeared in the world since the area of scientific and technical progress will spread to Africa (and in particular to Cameroon), climate warming and flood being the constant consequence of human action on the environment. These ecological phenomena (including drought) are responsible for social problems such as famine in the northern region of country as a priority. This study therefore proposes in historical logic, how the drought has impacted on the proliferation of famine on northern Cameroon, thus reducing this region to the rank of priority food (RPF).

Supporting families and young deaf children with a bimodal bilingual approach
Authors: Rowley Katherine , Snoddon Kristin , O'Neill Rachel
Published: November 2022

This article reviews research and presents recommendations concerning bimodal bilingualism for families with young deaf and hard of hearing children. Bimodal bilingualism means deaf children and their families have access to a national sign language in addition to other spoken/written languages. National sign languages are one or more of the sign languages that make up the linguistic ecology of a country, including but not limited to British Sign Language (BSL) in the UK and American Sign Language (ASL) in Canada. National sign languages have their own vocabulary, grammar, and social rules of use, and many sign languages are used by deaf communities around the world. Bimodal bilingualism and enhanced family communication have long-lasting benefits for deaf children’s development and wellbeing. We look at how to support early bimodal bilingual communication and literacy, and the role of practitioners in guiding families.

Published: November 2022

Ureaplasma spp. are frequently isolated from the genital tract of women of reproductive age. To date, it remains unclear whether they are commensal or pathogenic. In our study, we assessed the prevalence of Ureaplasma spp. in a group of 1,155 women of childbearing age. In addition, we assessed how often women with positive Ureaplasma spp. develop genital tract co-infections and how the vaginal pH changes. This study showed a relationship between colonization by Ureaplasma spp. and presenting symptoms. In fact, we showed that colonization of the genital tract by Ureaplasma spp. can affect the occurrence of co-infections such as Gardnerella vaginalis. We also observed a relationship between increased pH values and the presence of Ureaplasma spp.

Published: November 2022

Tekanan pori formasi merupakan data penting yang digunakan dalam mendesain parameter dalam operasi pengeboran. Kesalahan dalam menentukan tekanan pori formasi dapat menimbulkan permasalahan dalam pengeboran yang dapat menyebabkan bertambahnya biaya pengeboran hingga kehilangan nyawa pekerja. Tekanan pori bisa didapatkan melalui pengukuran langsung maupun menggunakan metode empiris. Pengukuran langsung tidak dilakukan di setiap kedalaman karena biayanya yang tinggi. Metode empiris memiliki keterbatasan dalam menentukan tekanan pori formasi dikarenakan metode ini memerlukan adanya keakuratan dalam analisis Normal Compaction Trendline dan batasan untuk digunakan pada formasi tertentu. Penelitian ini menggali potensi jaringan saraf tiruan untuk memprediksi tekanan pori berdasarkan data logging sumur. Dengan arsitektur jaringan saraf tiruan yang menggunakan tiga hidden layer, model dibangun dengan lima fungsi aktivasi dan metriks evaluasi Mean Absolute Error. Semua mampu memprediksi tekanan pori dengan baik yang ditunjukkan dengan nilai loss dibawah 0.5. Diantara kelima fungsi aktivasi, Exponential Linear Unit menghasilkan loss paling baik sebesar 0.07 dibanding model dengan fungsi aktivasi lainnya.

Published: November 2022

Biofuels have been occupying space in the fuel market as a renewable substitute for petrol fuels. The thermal and/or thermo-catalytic cracking using triglyceride biomass stands out among the biofuel production processes. Cracking processes result in the production of coke, bio-oil and non-condensable gases. The quantification of each product in a cracking process is directly linked to operational conditions. This project focuses on the use of residual fat from the poultry processing industry, converting it into biofuel so that it can be used in the industry itself as a source of energy. The quality of the products generated are linked to the raw material used, as well as the conditions used in the cracking process. One way to improve the characteristics of the bio-oil produced can be achieved with the use of a catalyst together with thermal cracking. The literature has shown that in thermo-catalytic cracking, there is lower yield in bio-oil, but with some properties, such as acidity and viscosity closer to the value required by legislation for use in engines. This project aims to add value to an industrial waste, by converting this waste into biofuel using thermo-catalytic cracking, with the possibility of being used in the industry itself, as well as investigating the optimization of the process to improve the quality of bio-oil. The yield of the liquid fraction was around 67 % with an acid value of 58.74 mg KOH/g sample.

Gazelles (Gazellaspp.) depicted in frescoes and sculpture from Herculaneum and Pompeii
Authors: Masseti Marco
Published: November 2022

Paintings and sculptures depicting gazelles ( Gazella spp.) are frequent in Ancient Roman art. Images of gazelles have been discovered during the archaeological explorations of Herculaneum and Pompeii, devastated by the eruption of Mount Vesuvius in ad 79. Two bronze statues of ungulates from the Villa of the Papyri, Herculaneum, now on display at the Museo Archeologico Nazionale di Napoli (National Archaeological Museum of Naples), have not been correctly identified, consequently causing erroneous speculation about their cultural significance. The aim of this paper is to suggest which gazelle species inspired these artefacts, and to also discuss the wider context of the artistic representations of gazelles from Herculaneum and Pompeii and their surroundings.

Authors: Edgington John A.
Published: November 2022

Three watercolour paintings by Richard Bradley, depicting plants from the East Indies and southern Africa, are described. The images of Coffea arabica (coffee) (Rubiaceae), Cinnamomum verum (cinnamon) (Lauraceae) and a southern African succulent, Cylindrophyllum calamiforme (Aizoaceae), are bound into contemporary volumes now held at the British Library, London. Also included in the cinnamon watercolour are two images of Sri Lankan butterflies. This paper sets these watercolours in the context of Bradley’s other paintings and colour illustrations. These three images, hitherto unpublished, were probably painted during Bradley’s visit to Holland in 1714.
Thomas MacGreevy’s Combatant Modernism
Authors: Davies William
Published: November 2022

This article examines Thomas MacGreevy’s poetry in the context of combatant modernism. It argues that the preoccupations with themes of perception and violence in MacGreevy’s poems represent a prolonged engagement with the First World War and its legacy in Irish and British culture and politics. The article considers how this reframing of MacGreevy’s work helps elaborate on combatant modernism as an intersecting tradition with the more familiar forms of European modernism represented by the work of T. S. Eliot, James Joyce and others, one in which recognizable techniques of fragmentation and disorientation are brought about not just by aesthetic experimentation but the need to find novel modes of poetic witnessing suitable to the new kind of conflict and suffering the First World War represented. This reorientation places MacGreevy alongside writers such as David Jones and Richard Aldington to reveal how combat service generated its own kind of modernist writing.

Authors: Bolatov Aidos K. , Seisembekov Telman Z. , Dauyenov Ernur , Zhorokpayeva Meiramgul D. , Smailova Dariga S. , Pavalkis Dainius
Published: November 2022

Background

The coronavirus disease (COVID-19) pandemic has affected medical education and psychosomatic health of medical students. In this follow-up study, conducted 1 year after the transition to online learning (OL), we aimed to investigate changes in student mental health and identify factors associated with academic burnout and changes in medical education caused by the pandemic.

Materials and methods

This study compares the burnout rate and psychosomatic status (depression, anxiety, somatic symptoms) of medical students at Astana Medical University using an online questionnaire-based repeated cross-section design of the pre-pandemic period (September–November 2019), the initial period of the pandemic (April 2020), and the current study (March 9–30, 2021). In the pre-pandemic period, students studied only in a face-to-face format. Moreover, the current study (March, 2021) analyzed factors associated with academic burnout and changes in medical education caused by the pandemic. Statistical methods included mean comparison, frequency, and regression analysis.

Results

Data from a representative sample of undergraduate students were analyzed (n = 975, 58% of them participated in the previous study). The burnout rate was found to be lower compared with the period of traditional education (pre-COVID-19) and did not significantly differ from the initial period of the introduction of online learning (the initial period of the COVID-19 pandemic). The levels and prevalence of depression and anxiety also showed similar patterns. The prevalence of somatic symptoms has increased compared to the initial period of the pandemic, although it has not reached the level obtained in the pre-COVID-19 period. The negative changes caused by OL in medical education and learning effectiveness have been associated with burnout. Factors associated with burnout, learning effectiveness, dissatisfaction with the quality of OL organization, and deterioration of medical education have been identified.

Conclusion

The medical education and mental health of medical students has undoubtedly undergone changes in the transition to OL due to the COVID-19 pandemic. Factors such as changing the content of education, the organization of the educational process and support from the school, the nature of student-teacher, student-school and student-student relationships, the possibility of mastering various skills and financial problems caused by the pandemic, played a significant role in the academic life of students. The results obtained have potential applications in organizing and improving the quality of continuing medical education in an era of global healthcare crises such as the COVID-19 pandemic.

Then, a series of advanced structural biology methods, including high-throughput screening, pharmacological characteristic prediction, precise molecular docking, molecular dynamics simulation, etc., was implemented to discover novel natural inhibitor materials against the MAPKAPK2 protein.

Results

The brown module containing 720 genes was identified as the interested module, and a group set of genes was determined as the hub OS-related genes, including PPP1R15A, CYB5R3, BCL2L1, ABCD1, MAPKAPK2, HSP90AB1, CSF1, RELA, P4HB, AKT1, HSP90B1, and CTNNB1. Functional analysis demonstrated that these genes were primarily enriched in response to chemical stress and several OS-related functions. Then, Novel Materials Discovery demonstrated that two compounds, ZINC000014951634 and ZINC000040976869, were found binding to MAPKAPK2 with a favorable interaction energy together with a high binding affinity, relatively low hepatoxicity and carcinogenicity, high aqueous solubility and intestinal absorption levels, etc., indicating that the two compounds were ideal potential inhibitor materials targeting MAPKAPK2.

Conclusion

This study found a group set of OS-related biomarkers of OP, providing further insights for OS functions in the development of OP. This study then focused on one of the macromolecules, MAPKAPK2, to further discover potential novel materials, which was of great significance in guiding the screening of MAPKAPK2 potential materials.

Receptor models are rarely utilized in atmospheric deposition but are often used to identify pollutant sources and quantify their contributions. This article focuses on the soil in atmospheric deposition in a typical polluted city. Atmospheric deposition has become an important route for exogenous heavy metals’ input into ecosystems. In this study, the heavy metals in atmospheric deposition were determined in three monitoring points arranged in Handan City. According to the functional area, fluxes, sources, and accumulation in the soil were explored. The sources of heavy metals were identified by PMF (positive matrix factorization) and UNMIX. The accumulation of heavy metals in the soil was predicted. The results showed that the deposition fluxes in industrial areas were higher than other functional areas. The mean concentrations of 8 heavy metals (Cd, Cr, Cu, Mn, Ni, Pb, Zn, and As) in the atmospheric deposition exceed their background values. PMF identified five major sources and UNMIX analyzed four sources. Similar source apportionment results were acquired via PMF and UNMIX, which were the combustion of fossil fuels, steel-smelting emission, road dust, and industrial sources. Steel-smelter emission was the highest source contributor. Therefore, combining these two models was the most effective approach, and more attention should be paid to mitigating the pollution caused by the industrial activities. The prediction indicated that the accumulation of heavy metals from atmospheric deposition to the soil would increase in 30 years, the growth rate of Cd increased significantly. The results of this study could provide reference in reduction of heavy metal pollution in atmospheric deposition.

Cerebral ischemia-reperfusion injury (CIRI) is common in ischemic stroke and seriously affects the prognosis of patients. At present, N6-methyladenosine (m6A) modification of lncRNAs and mRNAs has been reported in other diseases, such as cancer, but its role in CIRI has not been clarified. In this study, we aimed to investigate the m6A lncRNA and m6A mRNA modification profiles in CIRI. First, we detected the total level of m6A and the changes in related m6A methyltransferases and demethylases in the brain tissue of rats with CIRI and then identified differentially modified lncRNAs and mRNAs in CIRI by lncRNA and mRNA epigenetic transcriptomic microarray. In addition, bioinformatics analysis was used to predict the underlying functions and related pathways of related lncRNAs and mRNAs. We found that the total m6A methylation level was significantly increased, and the expression of fat mass and obesity-associated protein (FTO) was downregulated after CIRI. In addition, a large number of m6A-modified lncRNAs and mRNAs appeared after CIRI, and these genes were mainly enriched for the Toll-like receptor signaling pathway, peroxisome proliferator-activated receptor (PPAR) signaling pathway, and mitogen-activated protein kinase (MAPK) signaling pathway. Our findings provide the basis and insights for further studies on m6A modification in CIRI.

Whilst short-term oral pre-exposure prophylaxis (PrEP) with antiretroviral drugs in men who have sex with men has shown protection against HIV-1 infection, the impact of this regimen on the in vivo foreskin transcriptome is unknown. We collected foreskin tissue after voluntary medical male circumcision from 144 young men (72 from Uganda and 72 from South Africa) randomized to one to two doses of either oral tenofovir (TFV) disoproxil fumarate (FTC-TDF) or tenofovir alafenamide (FTC-TAF) or no drug (untreated controls). This novel approach allowed us to examine the impact of short-term oral PrEP on transcriptome of the male genital tract. A single dose of FTC-TDF did not affect the foreskin transcriptome in relation to control arm, however one dose of FTC-TAF induced upregulation of four genes AKAP8, KIAA0141, HSCB and METTL17. Following two doses of either FTC-TDF or FTC-TAF, there was an increase in 34 differentially expressed genes for FTC-TDF and 15 for FTC-TAF, with nine DEGs in common: KIAA0141, SAFB2, CACTIN, FXR2, AKAP8, HSCB, CLNS1A, DDX27 and DCAF15. Functional analysis of differentially expressed genes revealed modulation of biological processes related to mitochondrial stress (KIAA0141, HSCB and METTL17), anti-viral and anti-inflammatory pathways (CACTIN and AKAP8). Our results show that short-course on-demand oral PrEP in men modulates genes in foreskin tissue which are likely unfavorable to HIV acquisition and replication. We also describe an upregulated expression of genes involved in diverse mitochondria biology which may potentially result in worsened mitochondria-related. These results warrant further studies to assess the role of short-course and prolonged oral PrEP on biological processes of the foreskin mucosa.

Published: November 2022

Spinal cord injury (SCI) is a pathological condition that leading to serious nerve damage, disability and even death. Increasing evidence have revealed that circular RNAs (circRNAs) and mRNA are widely involved in the regulation of the pathological process of neurological diseases by sponging microRNAs (miRNAs). Nevertheless, the potential biological functions and regulatory mechanisms of circRNAs in the subacute stage of SCI remain unclear. We analyzed the expression and regulatory patterns of circRNAs and mRNAs in SCI mice models using RNA-sequencing and bioinformatics analysis. A total of 24 circRNAs and 372 mRNAs were identified to be differentially expressed. Then we identifying the immune-related genes (IRGs) from them. The protein-protein interaction network were constructed based on the STRING database and Cytoscape software. Furthermore, Go and KEGG enrichment analysis were conducted to predict the functions of the IRGs and host genes of DECs. These findings will contribute to elucidate the pathophysiology of SCI and provide effective therapeutic targets for SCI patients.
Autoreactivity and broad neutralization of antibodies against HIV-1 are governed by distinct mutations: Implications for vaccine design strategies

Published: November 2022

Many of the best HIV-1 broadly neutralizing antibodies (bnAbs) known have poly-/autoreactive features that disfavor normal B cell development and maturation, posing a major hurdle in developing an effective HIV-1 vaccine. Key to resolving this problem is to understand if, and to what extent, neutralization breadth-conferring mutations acquired by bnAbs contribute to their autoreactivity. Here, we back-mutated all known changes made by a prototype CD4 binding site-directed bnAb lineage, CH103-106, during its later maturation steps. Strikingly, of 29 mutations examined, only four were crucial for increased autoreactivity, with minimal or no impact on neutralization. Furthermore, three of these residues were clustered in the heavy chain complementarity-determining region 2 (HCDR2). Our results demonstrate that broad neutralization activity and autoreactivity in the CH103-106 bnAb lineage can be governed by a few, distinct mutations during maturation. This provides strong rationale for developing immunogens that favor bnAb lineages bearing “neutralization-only” mutations into current HIV-1 vaccine designs.

Published: November 2022

Background

Lipoma is the most common benign mesenchymal tumor that is composed of mature fat cells. Subdermal laser lipoma treatment may be recommended as an alternative to surgery for its removal.

Purpose

The purpose of the study was to investigate the efficacy of the 1,444 nm Nd:YAG laser subcutaneous intralesional application as a treatment option for lipoma.

Materials and methods

On 60 patients (37 women and 23 men) with lipomas localized above the muscle and lipomatosis in various regions, a subcutaneous, micro-pulsed 1,444 nm Nd:YAG laser procedure was executed. Before treatment, an ultrasound was performed and the lipomas were measured. The same lighting setup and photographic tools were used to take pictures of each patient.

Results

The lipoma reduced or completely disappeared in all cases at the last follow-up, and no infections, burns, skin lesions, episodes of severe bleeding, or other serious adverse effects were reported. The most common transient side effects were ecchymosis and edema. Partial lesion reduction refers to rare cases of lipomatosis in which the lipomas were so small that suction and accurate positioning of the capsular membrane contours were impossible.

Conclusion

Lipoma treatment with a 1,444 nm Nd:YAG laser is a safe and effective minimally invasive procedure without risk of scarring. For cellular disruption, laser treatment is an effective and safe option.

Background

While point-of-care ultrasound (POCUS) has been used to track worsening COVID-19 disease it is unclear if there are dynamic differences between severity trajectories.

Methods

We studied 12-lung zone protocol scans from 244 participants [with repeat scans obtained in 3 days (N = 114), 7 days (N = 53), and weekly (N = 9)] ≥ 18 years of age hospitalized for COVID-19 pneumonia. Differences in mean lung ultrasound (LUS) scores and percent of lung fields with A-lines over time were compared between peak severity levels (as defined by the WHO clinical progression scale) using linear mixed-effects models.

Results

Mean LUS scores were elevated by 0.19 (p = 0.035) and A-lines were present in 14.7% fewer lung fields (p = 0.02) among those with ICU-level or fatal peak illness compared to less severe hospitalized illness, regardless of duration of illness. There were no differences between severity groups in the trajectories of mean LUS score 0.19 (p = 0.66) or percent A-lines (p = 0.40).

Discussion

Our results do not support the use of serial LUS scans to monitor COVID-19 disease progression among hospitalized adults.
