Authors: Abd Rashed Aswir , Jamilan Mohd Azerulazree , Abdul Rahman Salina , Amin Nordin Fatimah Diana , Mohd Nawi Mohd Naeem
Published: October 2024

Microorganisms such as bacteria, viruses and fungi are frequently the cause of infections. Antimicrobial agents, such as antibiotics, antivirals, and antifungals, are used to target and eliminate these infectious agents. Treating infections is crucial to prevent them from spreading, causing complications, or becoming chronic. On the other hand, inflammation is a natural response of the immune system to injury, infection, or irritation. While acute inflammation is a natural and protective process, chronic inflammation can contribute to various health issues, including autoimmune diseases, allergies, and chronic conditions like arthritis. Although herbal remedies have been used for centuries and can be effective in certain situations, it is crucial to use them with caution. Not all herbal remedies are supported by scientific evidence, and their safety and efficacy can vary. Thus, we conducted this review to determine the potential health benefits of agarwood as an antimicrobial and anti-inflammatory agent. Original articles were searched in three databases (PubMed, Scopus and Google Scholar) from the year 2013 to 2023 using the Medical subject heading (MeSH) terms “antimicrobial” and/or “anti-inflammatory”, crossed with the term “agarwood”. Synonyms and relevant search terms were also searched.  The most studied agarwood for antimicrobial and anti-inflammatory agents is Aquilaria sinensis. Some studies have shown its potential application as a biopesticide for mosquito control and as a potent inhibitor for fungi, including Lasiodiplodia theobromae, Fusarium oxysporum, and Candida albicans. Moreover, it is capable of inhibiting Bacillus subtilis and Staphylococcus aureus activities. In conclusion, agarwood and its isolates are worthy of further biomedical investigation and could be developed as potential candidates for the treatment or prevention of various microbial and inflammatory diseases. This review reveals that despite the absence of clinical trials, agarwood exhibits antimicrobial and anti-inflammatory properties.

Authors: Jo Yu-Jeong , Park Seung-Woo , Shin Ueon Sang , Kim Seung-hoi
Published: October 2024

Cysteine plays a crucial role in the development of an efficient copper-catalyst system, where its thiol group serves as a strong anchoring site for metal coordination. By immobilizing copper onto cysteine-modified, polydopamine-coated magnetite nanoparticles, this advanced catalytic platform exhibits exceptional stability and catalytic activity. Chemical modification of the polydopamine (PDA) surface with cysteine enhances copper salt immobilization, leading to the formation of the Fe₃O₄@PDA-Cys@Cu nanostructure. This system was evaluated in palladium-free, copper-catalyzed Sonogashira coupling reactions, effectively catalyzing the coupling of terminal acetylenes with aryl halides. Additionally, the Fe₃O₄@PDA-Cys@Cu platform was employed in click reactions, confirming the enhanced catalytic efficiency due to increased copper content. The reusability of the platform was further investigated, demonstrating improved performance, especially in recyclability tests in click reaction, making it a promising candidate for sustainable heterogeneous catalysis.

Published: October 2024

Background: Influenza is a highly contagious viral virus that affects millions of people globally each year, causing major morbidity, mortality, and economic consequences. Despite vaccine availability, seasonal flu outbreaks continue, exacerbated by virus mutations and varied transmission patterns. The Eastern Cape region of South Africa faces specific obstacles when it comes to flu management, such as limited healthcare access and dependence on traditional treatments. Methods: Patients from various backgrounds in the rural Eastern Cape who had flu and consented to be participants of the study were surveyed to assess symptom severity, duration, and management options. To compare the efficacy of medical treatments with home cures, data was analysed using descriptive statistics and independent t-tests. Results: Symptom severity ranged from mild to severe, and the average duration of symptoms varied according to the therapy approach chosen. Medical therapies, including antiviral drugs, were found to lessen symptom severity and duration, whereas home cures provided symptomatic relief but were less successful in severe cases. Symptom severity differed significantly between therapy methods (p < 0.05).Conclusions: The study emphasises the significance of prompt medical attention in managing influenza symptoms, especially in high-risk individuals. It also emphasises the importance of increasing access to healthcare in the Eastern Cape in order to improve outcomes for flu patients.

Authors: Borges da Silva Fernanda Aparecida , Florindo Joao Batista , Mattos Amilcar Castro de , Costa Fernando Ferreira , Lorand-Metze Irene , Metze Konradin
Published: October 2024

In recent studies it has been shown that fluorescence lifetime imaging (FLIM) may reveal intracellular structural details in unstained cytological preparations which are not revealed by standard staining procedures. The aim of this investigation was to show whether FLIM images could reveal areas suggestive of polymerization in red blood cells (RBCs) of sickle cell disease (SCD) patients. We examined air-dried unstained blood films using auto-fluorescence FLIM images of 45 SCD patients and compared the results with those of 27 control persons without hematological disease. All control RBCs revealed homogeneous cytoplasm without any foci. Rounded non-sickled RBCs in SCD showed between zero and three small intensively fluorescent dots with higher lifetime values. In sickled RBCs we found additionally larger irregularly shaped intensively fluorescent areas with increased FLIM values. These areas were interpreted as equivalent to polymerized hemoglobin. The rounded non-sickled RBCs of SCD patients with homogeneous cytoplasm were not different from those of erythrocytes of control patients in light microscopy.
Yet, variables from the local binary pattern transformed matrix of the FLIM values per pixel, showed significant differences between non-sickled RBCs and those of control cells. In a linear discriminant analysis, using local binary pattern transformed texture features (mean and entropy) of the erythrocyte cytoplasm of normal appearing cells, the final model could distinguish between SCD patients and control persons with an accuracy of 84.7% of the patients.

Authors: Kumar Suresh , K Himanshu , Gaur Pratibha , Pandey Ramendra Pati , Raj V. Samuel
Published: October 2024

A major cause of genital discomfort in women around the world is bacterial vaginosis, which results from excessive growth of pathogenic bacteria in the vaginal ecosystem. Current treatment consists of antibiotics and/or probiotics, which show favourable therapeutic effects, but also cause problems such as drug resistance and recurrence. Considering faecal transplantation's success, transplantation of vaginal fluid from healthy donors could provide the most effective treatment for bacterial vaginosis. However, experimental treatments have shown that vaginal microbiome transplantation may not be a one-size-fits-all solution. The present article examines the limitations of current standardized therapy, the advantages of vaginal microbiome transplantation, and presents future novel strategies for treating bacterial vaginosis based on current research findings and clinical trials development worldwide.

Published: October 2024

The incorporation of unconventional feed ingredients in animal husbandry aims to improve nutritional efficiency and animal health. Bamboo, known for its rich mineral, antioxidant, and dietary fiber content, represents a potential alternative feed ingredient. This study explores the effects of fermented bamboo powder (FBP) on growth performance, antioxidant status, intestinal morphology, and expression of nutrient transporter genes in broiler chickens. 600 healthy 1-day-old chicks were randomly divided into two groups, each with 10 replicates of 30 chicks. The control group was provided with a basal diet. The experimental group was given the basal diet with supplemented 1.0 and 2.0 g/kg FBP for two different stages: phase Ⅰ (1-22 days) and phase Ⅱ (23-45 days). The results indicated a significant improvement in growth performance of the group fed with fermented bamboo powder compared to the control group (P < 0.05). More-over, there was a significant effect on the weight of organs and muscles when compared to the control group (P < 0.05). Moreover, there was a significant effect on triglyceride levels (P < 0.05), with a positive effect on urea and creatinine levels (P < 0.05), as well as a significant improvement in the levels of antioxidant enzymes (MDA, SOD, and CAT) compared to the control group (P < 0.01). In contrast, fermented bamboo powder significantly enhanced the surface area available for nutrient absorption in the intestine (duodenum, jejunum, and ileum) by increasing the villus height, intestinal lumen depth, and villus area (P < 0.01). FBP increased the expression levels of genes involved in the transport of nutrients from the intestinal regions (duodenum, jejunum, and ileum) namely GLUT1, GLUT2, CAT1, CAT2, PEPT1, PEPT2, and LAT1, compared to control. The upregulation of nutrient transporter genes further facilitated nutrient absorption, contributing to the observed improvements in growth and body weight. These findings endorse FBP as a viable feed additive in broiler diets to enhance health and performance.

Published: October 2024

Starting from the objectives of the Nature Restoration Law and the concept of Forest Landscape Restoration, the objective of the following study is to present a methodological approach aimed at identifying areas that are best suited for the implementation of NbS for the improvement of landscape and habitat status in the study area identified by the Urban Atlas of the city of Campobasso (1028.64 km2). Using open data (ISPRA ecosystem services and Regional land use capability), an expert based approach (questionnaire) and a multi-criteria analysis (AHP), the Total Ecosystem Services Value (TESV) index was determined as a weighted additive sum of the criteria (Data) considered. The index was then classified into 8 clusters and the land use “Cropland” was extracted, matching Cluster 1 (740.09 Ha) with agricultural areas with less ES provision to be allocated to NbS and Cluster 8 (482.88 Ha) with valuable areas to be preserved, for a total of 2.34% of the study area. It was then possible to compare the “Forest” areas currently present in the study area with those of a possible future scenario, represented by the areas occupied today by forest with the addition of cluster 1 croplands. A landscape analysis was then conducted: it showed greater dispersion and fragmentation of forest patches in the future scenario but also greater connectivity and thus greater ecological functionality of the patches.
Assessing Mild Traumatic Brain Injury Associated Blood Brain Barrier (BBB) Damage and Restoration Using Late Phase Perfusion Analysis by 3D ASL MRI- Implications for Predicting Progressive Brain Injury
Authors: Joseph Charles R
Published: October 2024

Mild traumatic brain injury mTBI is a common occurrence around the world, associated with a variety of blunt force and torsion injuries affecting all age groups. Most never reach medical attention, and identification of acute injury and later clearance to return to usual activities is relegated to clinical evaluation particularly in sports injuries. Advanced structural imaging is rarely performed due to the usual absence of associated acute anatomic/hemorrhagic changes. This review targets physiologic imaging techniques available to identify subtle blood brain barrier dysfunction and white matter tract shear injury, and their association with chronic traumatic encephalopathy. These techniques provide needed objective measures to assure recovery from injury in those patients with persistent cognitive/emotional symptoms and in the face of repetitive mTBI.
Functional Foods in Preventing Human Blood Platelet Hyperactivity – Mediated Diseases
Authors: Duttaroy Asim K
Published: October 2024

Abnormal platelet functions are associated with human morbidity and mortality. Maintaining physiological platelet function is critical to hemostasis and preventing platelet-associated diseases such as cardiovascular disease, cancer metastasis, immune disorders, hypertension, diabetes, sickle cell disease, inflammatory bowel disease, sepsis, rheumatoid arthritis, myeloproliferative disease, and Alzheimer’s disease. Platelets become hyperactive in obesity, diabetes, a sedentary lifestyle, hypertension, pollution, and smokers. Platelets, upon activation, can trawl leukocytes and progenitor cells to the vascular injury sites. Platelets also release various pro-inflammatory, anti‐inflammatory, and angiogenic factors and shed microparticles in the circulation. The challenge for therapeutic intervention in these diseases will be identifying factors that preferentially block specific targets involved in platelets' complex contribution to inflammation or tumor progression while leaving their hemostatic function at least partially intact. Since antiplatelet drugs such as aspirin are not recommended as primary preventives, it is essential to use alternative safe platelet inhibitors. Potent natural antiplatelet factors were investigated, including n-3 fats, polyphenols, and other bioactive compounds. This review describes the anti-platelet bioactive compounds in food that can prevent platelet hyperactivity and thus may prevent several platelet-mediated diseases, including cardiovascular disease.
Phytochemical Characterization and Assessment of the Wound Healing Properties of Four “Poplar-Type” Propolis
Authors: Miraldi Elisabetta , Giordano Alessandro , Cappellucci Giorgio , Vaccaro Federica , Biagi Marco , Baini Giulia
Published: October 2024

Objectives: This study aimed to evaluate the potential of poplar-type propolis for wound healing by analyzing its phytochemical profile and biological effects.
Methods: The phytochemical characterization included specific colorimetric assays to estimate the total phenolic and flavonoid contents and the triterpenoids content. Some of the main components of poplar propolis (pinocembrin, pinobanksin, CAPE, chrysin, galangin) were analyzed using HPLC-DAD. Scavenging activity and total antioxidant capacity were assessed through DPPH and ORAC assays, respectively. Biological in vitro assays used keratinocyte, fibroblast, and monocytic cell lines. The direct wound healing properties were tested through scratching assays and ELISA kits for the assessment of the production of growth factors (FGF-7, Latency Associated Peptide - LAP), while the indirect effects were evaluated through the estimation of the levels of MMP9, IL-1β, IL-8 and TNF-α using ELISA kits together with a cell-free test on the inhibition capacity on collagenases. During the study, the Network Pharmacology analysis was employed to further explore possible mechanisms of action of propolis on the healing process.
Results: The analyses confirmed the high phenolic content of poplar propolis, dominated by flavonoids, and terpenes. Propolis exhibited significant antioxidant activity and interestingly, propolis showed indirect wound-healing properties by mitigating inflammation and remodeling (reduced IL-1β and MMP9) and potentially modulating the immune response (upregulated IL-8). In vitro studies confirmed these effects, demonstrating decreased MMP9 production and collagenase inhibition when cells were co-treated with propolis and a stressor. Propolis also suppressed IL-1β release in fibroblasts, although its impact on TNF-α was inconclusive. Notably, co-treatment upregulated IL-8 in monocytes, suggesting a potential immunomodulatory role.
Conclusion: poplar propolis may not directly stimulate cell proliferation during wound healing, while its anti-inflammatory and immunomodulatory properties could suggest an indirect contribution to the process.

Published: October 2024

In an attempt to replace corroding mild steel components in aggressive mine water environ-ments, nickel-chromium-iron (Hastelloy® G30), copper-nickel-tin (ToughMet® 3), and co-balt-chromium-tungsten (Stellite® 6B) hard alloys were selected due to their excellent corrosion resistance, but they remain challenged in many acidic environments. The corrosion behaviours of these alloys were compared and investigated in synthetic mine water with varying pH levels (6, 3, 1) using potentiodynamic polarisation. Microstructural, hardness, and XRD analyses were conducted. Stellite® 6B exhibited superior corrosion resistance across all pH values, outperform-ing both Hastelloy® G30 and ToughMet® 3. With the lowest corrosion rates and comparable high hardness, Stellite® 6B emerges as a promising choice for replacing mild steel pump components in aggressive mine water environments.

Published: October 2024

Age related macular degeneration (AMD) as the name suggest is the timely degradation of the macular area of the eye which can lead to vision impairment, in particular the central vision. Macular is one of the important areas of the eye, present in the retina which controls our central vision. AMD is one of the most common types of irreversible blindness caused in older population of the society in developed countries. AMD is broadly classified as Dry AMD (Non Neovascular AMD) and Wet AMD (Neovascular AMD). Non Neovascular AMD more commonly known as Dry AMD is less aggressive and is very frequent type of AMD caused, it has three stages 1) Early dry AMD, 2) Intermediate Dry AMD, and 3) Late AMD. One the several therapies used to treat AMD is stem cells where Induced pluripotent stem cells (IPSC’s) derived retinal pigment epithelium (RPE) cells was used to treat dry AMD. The use of siRNA that targets Vascular endothelial growth factor (VEGF-A) using different nanotechnology-based delivery system like the organic nanoparticles synthesized liposomes. An upcoming therapy used most widely in recent times is the photodynamic therapy where a photodynamic drug like verteporfin which a benzoporphyrin derivative is used, where the outcome shows great promise in reducing vision loss in wet AMD. This review discusses in details about age related macular degeneration and also its different novel therapies that is been currently used extensively.

Authors: Abaver Dominic
Published: October 2024

This study aimed to determine the prevalence and demographic distribution of schistosomiasis in the Eastern Cape Province of South Africa through a cross-sectional retrospective analysis using secondary data from patients with microscopically confirmed schistosomiasis collected between 2019 and 2020. The study focused on both rural and semi-urban areas, including Bizana, Butterworth, Centane, Elliotdale, Flagstaff, Idutywa, Lusikisiki, Libode, Mqanduli, Port St. Johns, Willowvale, and Mthatha. Data were obtained from three districts: Alfred Nzo, Amatole, and OR Tambo, covering both rural and semi-urban regions. The study included patients of all ages who submitted urine samples for schistosomiasis testing in the specified districts. A simple random sampling method was used to select 337 clinical records from the National Health Laboratory Service (NHLS) of Mthatha. Hospital records from the NHLS Microbiology Department of Mthatha were analyzed using SPSS version 20. Statistical tests, including Fisher’s exact test, Pearson’s Chi-squared test, and Wilcoxon rank sum test, were employed to compare demographic variables. The Shapiro-Wilk test was used to assess the normality of quantitative data. St Barnabas Laboratory had the highest frequency of cases (34.1%), followed by Greenville Depot (17.8%) and Willowvale Laboratory (11.3%). Most cases were in the 10-19 age group (63.4%), followed by those under 10 years (24.9%). Males constituted 76.4% of the cases, while females accounted for 23.6%. Viable ova were observed in 98.2% of the samples. The study highlights a significant prevalence of schistosomiasis in the Eastern Cape Province, with a higher incidence in rural areas and among males aged 10-19. These findings underscore the need for targeted public health interventions and continuous monitoring to control and prevent schistosomiasis in the region.
Can Vitamin D Be Supplied from the Large Intestine?
Authors: Fraser David
Published: October 2024

The discovery that vitamin D2 is being generated by anaerobic microbial metabolism in the alimentary tract, raises the question whether such a source of vitamin D could contribute to vitamin D supply for the animal hosting this microbial production system. In ruminants, this microbial generation in the forestomach allows vitamin D2 to be readily absorbed when it reaches the small intestine, contributing to vitamin D2 and 25-hydroxyvitamin D2 [25(OH)D2] found in their tissues. In monogastric animals like humans, the microbial generation of vitamin D2 is occurring in the large intestine. There is evidence that vitamin D hydroxy metabolites, delivered to the lumen of the colon can be absorbed. However, the parent vitamin D is more lipophilic than its metabolites, and like lipophilic vitamin K2 being produced by bacteria in the hindgut, may be poorly absorbed by the colon mucosa. It is now apparent that colon mucosal cells have the proteins megalin and cubilin in their basal membrane. These glycoproteins perform endocytosis of circulating proteins including vitamin D binding protein [DBP]. Inside the cell, DBP binds to cytoplasmic actin and thus provides an array of high affinity binding sites for vitamin D and its functional metabolites. Any traces of vitamin D2 that may diffuse into the colon mucosal cells from the lumen would thus be retained and accumulate on the DBP-actin. It would then be a substrate for functional hydroxylase metabolism for local endocrine action in these cells, and subsequent delivery of 25(OH)D2 by diffusion to apo-DBP in the circulation.

Published: October 2024

This study presents an optimized design for a Segmented Sinusoidal Parameter Winding with Magnetic Wedge Variable Reluctance Resolver (SSPWMW-VRR), addressing challenges like winding asymmetry and harmonic distortion in conventional designs. By integrating Particle Swarm Optimization (PSO) for winding design, Magnetic Equivalent Circuit (MEC) analysis for leakage flux, and machine learning techniques (XGBoost and Multi-Layer Perceptron), the stator slot shape was fine-tuned for improved accuracy. XGBoost outperformed MLP in prediction accuracy with a Mean Absolute Error (MAE) of 0.1172. Finite Element Analysis (FEA) simulations and experimental validation demonstrated a reduction in position errors from ±30’ in conventional VRRs to ±5’ in the optimized design, along with significant harmonic reduction.
Polymer Electrolytes for Supercapacitors
Authors: Chen Xuecheng , Holze Rudolf
Published: October 2024

Because of safety concerns associated with the use of liquid electrolytes and electrolyte solutions options of non-liquid materials like gels and polymers used as ion conducting electrolytes have been explored intensely. The low ionic conductivity of hard and soft solid materials was too low for practical applications in supercapacitors which require low internal reistance of a device and consequently highly conducting materials. Even if an additional separator may not be needed when the solid electrolyte already ensures reliable separation of the electrodes the electrolytes prepared as films or membranes as thin as practically acceptable resistance may still be too high. Recent developments with gel electrolytes sometimes approach or even surpass liquid electrolyte solutions in terms of effective conductance. Reported studies are reviewed, material combinations are sorted out, trends are identified.
The Design of Highly Reflective All-Dielectric Metasurfaces Based on Diamond Resonators
Authors: Xing Zhongyang , Liao Jiahui , Xu Zhongjie , Cheng Xiangai , Zhang Jiangbin
Published: October 2024

All-dielectric metasurfaces offer a low-loss alternative to plasmonic metasurfaces. We proposed the configuration for high-reflectivity all-dielectric metasurfaces based on single-crystal diamond (SCD) resonators on fused silica substrate and conducted simulations to optimize and analyse such configuration via FDTD solver. We utilized GMR as design principles to select the configuration and the substrate material, and analyzed the scattering properties of a single SCD resonator by multipole decomposition. Then we have demonstrated that both the cylindrical resonators in square lattice and frustum-shaped resonators in hexagonal lattice can achieve near-unity reflectivity (> 99.99%) and ultra-low absorption (< 0.001%) at 795 nm, the typical alkali-metal laser wavelength. Additionally, we have demonstrated that such design is quite tolerant to fabrication errors and further supports its potential for realistic applications. To expand the functionality of such devices across multiple wavelengths, a dual-band high-reflectivity meta-surfaces at 744 nm and 828 nm has also been designed. Our work is quite useful for designing diamond-based highly reflective mirrors, paving the way for low-loss all-dielectric reflective metasurfaces in high-power laser applications.

Authors: Di Fabrizio Donatella , Mastroberti Francesca , Cruccetti Alba , Bindi Edoardo , Cobellis Giovanni
Published: October 2024

Aim: Esophageal atresia (EA) is the most common congenital esophageal malformation. Thoracoscopic repair is gaining popularity, but controversy persist regarding the ideal surgical approach for this challenging anomaly. Study’s aim is to analyze outcomes in terms of quality of life (QoL) of children undergoing thoracotomy and thoracoscopy for type III EA repair. Methods: Perinatal characteristics, malformations, surgical procedures, complications, gastrointestinal and respiratory current symptoms were collected. QoL were investigated through Esophageal-Atresia-QoL(EAQoL) and Pediatric-QoL(PedsQL)4.0 standardized and validated questionnaires. Statical Mann-Whitney test with significance level p <0.05 was carried out. Main results: A total of 32 patients undergoing type III EA primary repair answered the questionnaire, including 17 thoracotomy and 15 thoracoscopy. Median birth weight was not significantly different between two groups (median[2.385;2.475], p=.3529) while gestational age showed statistically difference (median[36;38], p=.0063). Thirty-five associated malformations (15 thoracotomy, 20 thoracoscopy) in 23 patients were observed. Postoperative complications occurred in 9 patients in thoracotomy group (1 recurrent fistula, 2 leakages, 6 stenosis) and in 6 patients in thoracoscopic group (2 recurrent fistula, 4 stenosis). Analyzing EAQoL we found statistically significant difference in physical health between the two groups (median[83;96], p=0.0119), while there was no difference in social relations, eating and total score (median[100;100], p=0.3473)(median[91;97], p=0.5749)(median[91;96], p=0.1710). Investigating PedsQL, psychosocial-health score (median[88;98], p=0.0069) and total score (median [91;99], p=0.0043) were statically significant different between the groups, whereas there was no difference for physical-health score (median[91;100], p=0.0706). Conclusions: Thoracoscopic EA repair is safe and feasible, allowing patient to have a better QoL in terms of physical and psychosocial health score.

Authors: Jesús-Azabal Manuel , Zheng Zhang , Bingxia Gao , Jing Yang , Soares Vasco N.G.J.
Published: October 2024

5G Mobile Adhoc Networks (5G-MANETs) are a popular and agile solution for data transmission in local contexts, while maintaining communication with remote entities via 5G. These characteristics have established 5G-MANETs as versatile communication infrastructures for deploying contextual applications, leveraging physical proximity while exploiting the possibilities of the Internet. As a result, there is growing interest in exploring the potential of these networks and their performance in real-world scenarios. However, the management and monitoring of 5G-MANETs is challenging due to their inherent characteristics, such as highly variable topology, unstable connections, energy consumption of individual devices, message routing, and occasional inability to connect to 5G. Considering these challenges, the proposed work aims to address real-time monitoring of 5G-MANETs using a connection-aware Digital Twin (DT). The approach provides two main functions: offering a live virtual representation of the network, even in scenarios where multiple nodes lack 5G connectivity, and estimating the performance of the infrastructure, enabling the specification of customized conditions. To achieve this, a communication architecture is proposed, analyzing its components and defining the involved processes. The DT is implemented and evaluated in a laboratory setting, assessing its accuracy in representing the physical network under varying conditions of topology and Internet availability. The results show 100% accuracy for the DT in fully connected topologies, with ultra-low latency averaging under 80 ms, and suitable performance in partially connected contexts, with latency averages below 3000 ms.

Oxidative stress, resulting from an imbalance between free radical production and antioxidant defenses, can negatively impact animal health, welfare, and productivity. In livestock, diseases are often correlated with reduced antioxidant status. To mitigate oxidative stress, natural antioxidants have gained attention as alternatives to synthetic compounds. The growing need for safe and natural animal products has led to the increased use of plant food additives (PFAs) as antioxidants in animal feed. These natural sources include plant extracts, essential oils, and bioactive compounds-rich by-products. Such antioxidants can enhance product quality, oxidative stability, and shelf life in ruminants, swine, and rabbits. Additionally, maintaining a good antioxidant status positively affects meat quality parameters, including vitamin E content and reduced lipid peroxidation. This review explores the properties of natural antioxidants, extraction methods, and their significance in promoting animal welfare, performance, and product quality.
An Orthologics Study of the Notch Signalling Pathway
Authors: Stein Wilfred Donald
Published: October 2024

The Notch signaling pathway plays a major role in embryological development and in the ongoing life processes of many animals. Its role is to provide cell-to-cell communication in which a Sender cell, bearing membrane -embedded ligands, instructs a Receiver cell, bearing membrane- embedded receptors, to adopt one of two available fates. Elucidating the evolution of this pathway is the topic of this paper, which uses an orthologs approach to build a firm base for such a study. Using BLAST searches, orthologs were identified for all of the 49 listed components of the Notch signaling pathway. The time course of the integration of these proteins as animal evolution proceeded was elucidated. Insofar as cell –to-cell communication is only of relevance in multicellular animals, it is not surprising that the Notch system reached a fully-working configuration only with the evolutionary appearance of the Metazoa, the first multicellular animals The roles of the Notch system’s 49 components in contemporary descendants of the ortholog-contributing ancestors were ascertained from a survey of the literature. A single protein, the protein tyrosine kinase (PTK) of the protozoan Ministeria vibrans was identified as a possible pre-Metazoan ancestor of the DLL, JAG, and NOTCH proteins. A scenario for the evolution of the Notch signaling pathway is presented and described as the co-option of its components, clade by clade, in a repurposing of genes already present in the ancestral unicellular organisms.

Published: October 2024

In biology and medicine, synthetic polymers that mimic intrinsically disordered proteins (IDPs) exhibiting remarkable structural and conformational flexibility due to their lack of stable three-dimensional structures are highly desirable. This conformational flexibility facilitates self-organization, making such polymers highly useful for various biomedical applications. Specifically, intrinsically disordered synthetic polymers show great potential in drug delivery systems, organ transplantation, artificial organ design, and ensuring immune compatibility. There is a pressing need for new synthesis and characterization techniques to develop these polymers which are modeled after intrinsically disordered proteins and can be used for various biomedical purposes. In this paper, we outline our strategies for designing intrinsically disordered synthetic polymers for biomedical applications. These design approaches are inspired by the properties of intrinsically disordered proteins and use of disorder promoting oligopeptides.
Combating Greenwashing of Construction Products: A Critical Analysis of Environmental Product Declarations

Published: October 2024

Global initiatives such as the Paris Agreement and Agenda 2030 have united nations around common sustainability goals, prompting critical discussions about the true nature of sustainability. A significant concern highlighted by the United Nations is greenwashing—a practice where companies or organisations mislead the public about the environmental benefits of their products or services. Tactics employed in greenwashing include using unclear or misleading labels like “green” and “eco-friendly” or emphasising a single aspect of the product’s lifecycle that appears sustainable while ignoring others. Environmental Product Declarations (EPDs) have gained prominence in response to these challenges, particularly in New Zealand, where government climate declaration regulations have fuelled their demand. This study aims to comprehensively analyse existing EPDs for construction products by identifying and evaluating EPD programs, categorising product types, assessing the completeness of Life Cycle Assessment (LCA) information modules, and verifying the accuracy of declared impact values. The research methodology involves a systematic literature review, drawing data from reputable databases, including Scopus, Elsevier, Taylor & Francis, MDPI, and Emerald Insight, with data analysis conducted using ATLAS.ti 9 software. Examining the current state of EPDs in New Zealand’s construction sector, this study aims to highlight best practices, identify areas for improvement, and provide a foundation for enhancing the transparency and reliability of environmental impact assessments. The findings will contribute to ongoing efforts to combat greenwashing and promote genuine sustainability in construction projects, ultimately supporting the development of more environmentally responsible building practices.
Determining the Level of Threat in Maritime Navigation Based on the Detection of Small Floating Objects with Deep Neural Networks
Authors: Łącki Mirosław
Published: October 2024

The article describes the use of deep neural networks to detect small floating objects located in the own vessel’s path. The research aimed to evaluate the performance of deep neural networks by classifying sea surface images and assigning the level of threat resulting from the detection of objects floating on the water, such as fishing nets, plastic debris or buoys. Such a solution could function as a decision support system capable of detecting and informing the watch officer or helmsman about possible threats and reducing the risk of overlooking them at a critical moment. Several neural network structures were compared to find the most efficient solution, taking into account the speed and efficiency of network training and its performance during testing. Additional time measurements have been made to test real-time capabilities of the system. The research results confirm that it is possible to create a practical lightweight detection system with Convolutional Neural Networks that calculates safety level in real time.

Hydrogen sulfide (H₂S) is a highly toxic and corrosive gas commonly found in industrial emissions and natural gas processing, posing serious risks to human health and environmental safety even at low concentrations. Early detection of H₂S is therefore critical for preventing accidents and ensuring compliance with safety regulations. This study presents the development of porous ZnO/SnO₂ heterostructure gas sensors tailored for ultrasensitive detection of H₂S at sub-ppb levels. Utilizing a screen-printing method, we fabricated five different sensor compositions, ranging from pure SnO₂ to pure ZnO, and characterized their structural and morphological properties through X-ray diffraction (XRD) and scanning electron microscopy (SEM). Among these, sensor SnO₂/ZnO with composition weight ratio of 3:4 demonstrated highest response at 325 °C, achieving a low detection limit of 0.14 ppb. The sensor was evaluated for detecting H₂S concentrations ranging from 5 ppb to 500 ppb under dry, humid and N2 conditions. The relative concentration error was carefully calculated based on analytical sensitivity, confirming the sensor's precision in measuring gas concentrations. Our findings underscore the significant advantages of heterostructure formation in enhancing gas sensitivity, offering promising applications in environmental monitoring and industrial safety. This research paves the way for the advancement of highly effective gas sensors capable of operating under diverse conditions with high accuracy.
