Abstract

Background: Chad with 7,698 confirmed cases of infection and 194 deaths since the beginning of COVID-19 pandemics one of the African countries with the lowest reported cases[i]. However, this figure probably underestimates the actual spread of the virus, due to the low rate of diagnosis. High rate of asymptomatic infections reflects reality of SARS-CoV-2 infection in Chad. In this study, we estimated the seroprevalence and factors associated with SARS-CoV-2 infection.
Methods: A total of 1,290 samples were taken between September and December 2022 in 10 provinces of Chad. IgG antibodies to the nucleocapsid (N) protein of SARS-CoV-2 were identified by ELISA method.
Results: The overall seroprevalence was 83.0% [95% CI = 81.6% t- 85.5%], with variations between provinces, ranging from 99.22% [95% CI = 94% - 100%] in Moundou (Southern Chad) to 46.80% [95% CI = 36% -57%] in Biltine (Eastern Chad). Factors associated with the seroprevalence of SARS-CoV-2 were: military occupation (OR= 0.37 CI [0.80-1.77] p=0.025) and group blood (OR= 0.16 CI [0.02-1.06] p=0.058). Other factors, such as gender age, were not statistically associated with seroprevalence.
Conclusion Our results indicates that the seroprevalence of COVID-19 in Chad ranks among the highest in Africa. These estimates could guide the response and public health policy decisions. This could enhance the handling of upcoming outbreaks involving respiratory pathogens.

Published: February 2024

Abstract

Projection and equivalence concepts have been widely studied in the literature. In the present paper two nonlinear systems with the same number of inputs, but not the same number of state variables, are considered. Under mild assumptions, necessary and sufficient conditions are given for the existence of a submersion such that the higher dimensional system projects onto the other one locally. The solution to this problem has relevant applications, for instance in robotics. It includes as a special case the equivalence of nonlinear systems with no particular structure.

Abstract

Using organic amendments, such as biochar as a source of silicon can enhance plant resistance to various biotic stresses including insect pests and helps to minimize the overuse of pesticides. A field experiment was conducted in Randomized Block Design (RBD) using a bhendi variety Arka Anamika with twelve treatments and replicated thrice. Treatments involving various rates of basal application of silicon sources such as biochar and Rice Husk Ash (RHA) with the alternate foliar sprays of potassium silicate and azadirachtin to examine the effectiveness of biochar against bhendi shoot and fruit borer. The results of the filed experiments revealed that seed treatment with biochar @ 100 g/kg of seeds + basal application of biochar @ 75 kg/ha + foliar spray of 1% potassium silicate on 30 and 60 days after sowing (DAS) and 1% azadirachtin on 45 and 75 DAS (T9), showed a significant reduction in the population of bhendi shoot and fruit borer. This might be due to the high amount of silicon content compared to the other treatments. It was followed by seed treatment with biochar @ 100 g/kg of seeds + basal application of RHA @ 75 kg/ha + foliar spray of 1% potassium silicate applied on 30 and 60 DAS and 1% azadirachtin applied on 45 and 75 DAS (T10). The per cent reduction over untreated check observed was 52.28% in the treatment (T9), whereas it was 47.07% in the T10.

Abstract
The increasing interest in chiral light stems from its spiral trajectory along the propagation direction, facilitating the interaction between different polarization states of light and matter. Despite tremendous achievements in chiral light-related research, the generation and control of chiral pulse have presented enduring challenges, especially at the terahertz and ultraviolet spectral ranges, due to the lack of suitable optical elements for effective pulse manipulation. Conventionally, chiral light can be obtained from intricate optical systems, by an external magnetic field, or by metamaterials, which necessitate sophisticated optical configurations. Here, leveraging the high harmonic generation process, we propose a versatile tunable chiral emitter, composed of only two planar Weyl semimetals slabs, addressing the challenges in both spectral ranges. Our results open the way to a compact tunable chiral emitter platform in both terahertz and ultra-violet frequency ranges. This advancement holds the potential to serve as the cornerstone for integrated chiral photonics.

Abstract
Background: Even if functionally effective for benign prostatic hyperplasia (BPH) symptoms relief, the morphological changes in the prostatic urethra and bladder cavity resulting from Aquablation treatment are still unknown. This study aims to assess the feasibility, safety, and efficacy of Aquablation within one-year post-surgery, focusing on functional and endoscopic outcomes.
Methods: Prospective enrollment of patients undergoing Aquablation (10/2018–04/2023) included those with baseline International Prostate Symptom Score (IPSS) ≥10, prostate volume <80 mL, and Qmax ≤12 mL/s. Functional outcomes were evaluated at 1, 3, 6, and 12 months using uroflowmetry (Qmax), evaluation of post void residue (PVR), IPSS, Quality of life (QoL)-IPSS, Sexual Health Inventory for Men (SHIM), Male Sexual Health Questionnaire for ejaculatory dysfuncton(MSHQ-EjD) and Incontinence Severity Index (ISI). Cystoscopy at three months assessed ablation quality on a Likert scale (1-poor; 5-excellent). Measurements included cavity length post-treatment (bladder neck to distal prostatic cavity rim) and preserved prostatic tissue length at the apex (distal prostatic cavity rim to the sphincter). Additional evaluations encompassed veru-montanum preservation, presence of residual fluffy tissue or mucous flaps, ureteral orifices and bladder trigone injuries.
Results: Out of 109 enrolled patients, one-year follow-up displayed significant improvements in Qmax (+103.08%), PVR (-75.13%), IPSS (-86.36%), and IPSS-QoL (-80.00%). Aquablation had no impact on erectile function and continence, preserving ejaculatory function in 96.3%. Of the 106 patients undergoing the three-month cystoscopy, prostatic urethra patency was satisfactory to perfect in 96.2%, with a median cavity length of 24 ± 8.2 mm. Residual median lobe occurred in 11.3%, without significant impact on micturition outcomes. Positive outcomes included minimal fluffy tissue and mucosal flaps, and well-preserved ureteral meatuses, verumontanum, and bladder trigone.
Conclusion: Aquablation effectively alleviates BPH-related LUTS with minimal impact on ejaculation up to one year post-surgery. A three-month post-surgery endoscopic evaluation supports its safety, efficacy, and precise ablation planning.

Abstract

Background: Type 2 diabetes mellitus (T2DM) is a chronic metabolic disease that commonly results from a high-calorie diet and sedentary lifestyle, leading to insulin resistance and glucose homeostasis perturbation. Physical activity is recommended as one first-line treatment in T2DM, but it leads to contrasted results. We hypothesized that, instead of applying standard exercise protocols, the prescription of personalized exercise programs specifically designed to reverse the potential metabolic alterations in skeletal muscle could result in better results.
Methods: To test this hypothesis, we drew the metabolic signature of the fast-twitch quadriceps muscle, based on a combined unbiased NMR spectroscopy and RT-qPCR study, in several T2DM mouse models of different genetic background (129S1/SvImJ, C57Bl/6J), sex and aetiology (high-fat diet (HFD) or HFD/Streptozotocin (STZ) induction or transgenic MKR mice. Three selected mouse models with unique muscular metabolic signatures were submitted to three different swimming-based programs, designed to address each metabolic specificity.
Results: We found that depending on the genetic background, the sex, and the mode of TD2M induction, specific muscular adaptations occurred, including depressed glycolysis associated with elevated PDK4 expression, shift to β-oxidation, or deregulation of amino-acid homeostasis. Interestingly, dedicated swimming-based exercises designed to restore specific metabolic alterations in muscle were found optimal in improving systemic T2DM hallmarks, including a significant reduction in insulin resistance, the improvement of glucose homeostasis, and a delay in sensorimotor function alterations.
Conclusion: The muscle metabolism constitutes an important clue for the design of precision exercises with potential clinical implications for T2DM patients.
Exploring the Impact of Persistent Chemical Vortices on Solution Homogeneity in Laboratory-Scale Reactions
Authors: Farnell Thomas James John 
Published: February 2024

Abstract
This study investigates the impact of persistent chemical vortices in lab scale reactions involving drop-wise addition of reagent, utilising pH indicators to visualise the vortex. Through the comparison of different indicators, Yamada universal indicator emerged as the superior choice. A protocol for acidifying a magnetically stirred solution was developed, allowing precise comparisons of chemical vortex lifetimes across various variables. The study examines the effects of container geometry, bulk solution pH, dropping position, stirring speed, and solution viscosity on vortex dynamics. Notable findings include the significant increase in chemical vortex persistence with larger beaker sizes, a direct relationship between acid concentration and vortex lifetime, and the effect of dropping position on vortex stability which fits the Rankine vortex model. Furthermore, the study reveals a nuanced relationship between stirring speed and vortex persistence, with a loss of dependence observed at higher velocities. Additionally, a significant increase in vortex lifetime was observed with higher solution viscosity, which is explained by the diffusion of momentum expressed by the Javier-stokes equation. Opportunities for further research include refining experimental setups to optimise vortex dynamics and comparative studies between cylindrical beakers and round-bottom flasks to assess their resistance to vortex formation. These insights have implications for improving chemical mixing processes, particularly in small-scale research and development settings.

Abstract

Background:Mosquito-borne viruses cause various infectious diseases in humans and animals. Oya virus (OYAV) and Ebinur lake virus (EBIV), belonging to the genus Orthobunyavirus within the Peribunyaviridae family, are recognized as neglected viruses with the potential to pose threats to animal or public health. The evaluation of vector competence is essential for predicting the arbovirus transmission risk.
Methods: To investigate the range of mosquito vectors for OYAV and EBIV, four medically significant mosquitoes —Culex pipiens pallens, Culex quinquefasciatus, Aedes albopictus, and Aedes aegypti —were selected to measure their vector susceptibility through blood-feeding infection. The RNA copies and infection rates of various mosquito species were determined using RT-qPCR. Subsequently, susceptible mosquito species were examined to determine their vector competence.
Results: The results revealed that Cx. pipiens pallens can support in vivo infection and multiplication of OYAV, while Cx. quinquefasciatus, Ae. albopictus,and Ae. aegypti exhibit lower susceptibility. Furthermore, Cx. pipiens pallenscan be infected by EBIV, posing a potential risk of virus transmission (with a transmission rate of up to 15.4%) at 7 days post-infection. In contrast, Cx. quinquefasciatus and Ae. albopictus exhibited poor vector competence.
Conclusions: This study evaluated the possible transmission risk of OYAV and EBIV using four mosquito species. The findings indicate a potential risk of EBIV transmission in Cx. pipiens pallens.

Published: February 2024

Abstract
Geological studies are of great importance in order to observe the change of living species over the years, to make inferences by using the information provided by the observed species, and to understand the developing and changing structure of the world we live in over the years. However, the examination and interpretation of fossil specimens is a complex and lengthy process. Especially in thin sections where microfossil studies are carried out, more than one fossil and non-fossil structures are often observed together. The detection and classification of fossil specimens with the help of computers simplifies this process as much as possible compared to manual classification processes. This study represents a comparative analysis of three distinct image classification models: CNN, ResNet, and VGG. We developed a custom Convolutional Neural Network (CNN) architecture aimed at advancing the analysis and classification of geological specimens, particularly focusing on the Endless Forams dataset for the identification of benthic foraminiferas. This approach significantly improves the precision of fossil identification, leveraging deep learning to interpret complex image data efficiently. Additionally, we have identified the ResNet-50 and VGG-16 models as optimal for our research purposes due to their advanced capabilities in handling high-dimensional data and their effectiveness in capturing detailed image features. The findings, application for benthic foraminiferas reveal significant insights into the models' performance, underscored by rigorous statistical evaluation, offering a comprehensive understanding of their capabilities and limitations within the realm of image classification.
