Filamentous fungus (moulds) create secondary metabolites called mycotoxins, which can be dangerous. These minuscule molecules (typically less than 1 000 Da) are almost inescapably found in nature. Aspergillus, Penicillium, Fusarium, and Alternaria are among the fungal species that produce mycotoxins. If these secondary metabolites make their way into the food chain and production, they are harmful and have a big effect. In African countries like Nigeria that rely significantly on staple foods like grains, cereals, and nuts, mycotoxin contamination is especially problematic. Mycotoxins have attracted international interest due to their effects on human health, significant financial losses, and both domestic and international trade. Due to concerns about food safety and financial losses, the majority of research has been on aflatoxins, ochratoxin A, fumonisin, zearalenone, and Fusarium toxins, despite the fact that over 400 mycotoxins have been found. Understanding how interacting abiotic factors connected to climate change—particularly rising temperatures, higher CO2, and fluctuations in water availability—affect the relative risks of mycotoxin contamination and the effects on food safety and security especially in Africa is therefore of great interest. For food safety and a sustainable food supply, mycotoxin contamination must be avoided. Stricter regulations and enforcement, post-harvest management, preventative agricultural practices, infrastructure and policy improvements, increased surveillance and awareness, and investments in cost-effective detection techniques and research are all suggested as ways to address mycotoxin issues in Africa. In order to address mycotoxin prevalence, governments, research institutions, and non-governmental organisations should customise the few resources at their disposal. This will provide the best chance for the successful establishment of a sustainable food system in Africa. Data from thorough investigations of mycotoxins in food commodities are expected to aid in the creation of safer food and in determining the areas that require further study. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

An environmentally friendly technique was used to prepare titanium dioxide@ silver (core shell) (TiO₂@Ag NPs) using chard leaf extract, a natural stabilizer and reductant. A nanocomposite (NCs) of TiO₂@Ag supported by halloysite nanotubes (HNTs), TiO2@Ag/HNT NCs, was prepared under microwave irradiation. The microwave technique is used to accelerate the reaction and enhance the homogeneity of nanoparticle distribution. Spectroscopic and structural analyses were performed on the resulting nanocomposite. X-ray diffraction (XRD) revealed a clear crystalline structure with grain sizes ranging from 7 to 15 nm, with an average of ~11 nm, the transmission electron microscope (TEM) revealed that the size of nanoparticles in the TiO₂@Ag/HNT NCs sample ranges from 20 to 80 nm, with some localized agglomerations visible in specific areas. UV–Vis absorption spectra indicated significant optical activity in the visible and UV ranges, indicating improved photonic properties. Fourier transform infrared (FTIR) spectra revealed the presence of intergroup bonds. The active ingredients in the plant extract and the TiO2@Ag/HNT nanocomposite surface were found, indicating the extract’s role in stabilization. The zeta potential test showed good stability, with a value of −57 mV. The TiO₂@Ag/HNT NCs demonstrated high efficiency in the adsorption of heavy metal mercury (Hg(II)) from contaminated water, achieving a removal rate of 100%. This result reflects the unique effectiveness of the TiO₂@Ag/HNT and its outstanding ability to treat mercury pollution efficiently. These results demonstrate the potential for producing a multifunctional nanocomposite in an environmentally friendly and efficient manner, making it a practical option for various photocatalytic and water treatment applications. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.

Alcohol consumption remains a major global public health and social challenge, driven by complex interactions between biochemical processes and sociocultural dynamics. This study critically examines the chemical pathways of ethanol metabolism and their relationship with the social behavior patterns observed among individuals with alcohol use disorder (AUD). Drawing on an interdisciplinary narrative review of peer-reviewed literature in biochemistry, neuroscience, psychology, sociology, and public health, the paper synthesizes evidence on how alcohol dehydrogenase, aldehyde dehydrogenase, and cytochrome P450 (CYP2E1) pathways mediate intoxication, tolerance, dependence, and long-term physiological harm through acetaldehyde toxicity and oxidative stress. These biochemical mechanisms are analytically linked to neurochemical adaptations involving GABAergic, glutamatergic, dopaminergic, and stress-related systems that underpin craving, withdrawal, impaired self-control, and compulsive drinking. Beyond biological mechanisms, the study situates alcohol-related behaviors within broader social contexts, highlighting the roles of social learning, peer influence, stress coping, family dynamics, and cultural norms. Particular attention is given to low- and middle-income settings, with reference to Nigeria, where informal alcohol markets, gendered drinking norms, stigma, and weak treatment infrastructures intensify social and health consequences. The review identifies persistent fragmentation between biological and sociological research and underscores gaps in longitudinal, context-specific, and African-centered evidence. The study concludes that alcohol dependence is best understood as both a biochemical disorder and a socially embedded phenomenon, and it advocates for integrated, culturally responsive prevention, treatment, and policy approaches. © 2026 Taylor & Francis Group, LLC.

New spectrally nanocomposite films have been developed for high absorption performance. The polystyrene (PS) was dissolved in THF and blended with fixed concentrations of carbon nanotubes (CNT) and carbon nanofibers (CN) (5 wt. % CNT, 5 wt. % CN, and 2.5 wt. % CNT+CN) via the casting technique to produce nanocomposite films. Polymer nanocomposite films have been developed to create an economical coating that reinforces the poly (styrene) matrix. The coating exhibits high absorptivity; the optical properties were computed over a wavelength range of 250-1350 nm at 30 °C. The transmittance and reflectance were decreased, skin depth and optical density were increased, and the absorbance coefficient and dielectric constant were increased. The direct and indirect energy gap (Eg) of the films has decreased from 2.8 to 2.4 eV and from 3.4 to 2.9 eV after adding CNT with CN. The Urbach energy (Eu) has increased from 1.24 to 2.71 eV. The XRD test confirms that the films had amorphous structures. The SEM analysis was used to show the surface morphology of thin films. Consequently, the atomic force microscopy (AFM) measurements indicated an increase in surface roughness (SR) from 5.19 to 14.5 nm for the doped PS thin films, and the root mean square (RMS) roughness increased from 6.65 to 16.6 nm. These modified PS nanocomposite thin films find potential applications in various industries, including air transport components, light-emitting diodes, laser sensors, UV energy shielding, light-harvesting devices, memory devices, and light-conversion technologies.

The idea that food and medicine are similar has a long history, many substances have also been used both as food and traditional treatment remedies. Several plant-based therapeutic substances including those obtained from plants like Chrysanthemum morifolium, Lonicera japonica, Crocus sativus, and Lonicera macranthoides, are homologous for use both as medicines and food. These plants mostly consist of flavonoids, organic acids, terpenoids, and other active substances that have a range of medical benefits, such as anti-inflammatory, anti-tumor, and antioxidant properties as well as a wide range of nutritional and physiological impacts on the human body. Thus, they are used in functional foods and medicinal formulations. Furthermore, scientists have discovered credible ways by which naturally occurring substances that affect immunological responses including n-3 poly-unsaturated fatty acids, vitamins A, D, and E, conjugated linoleic acid and ascorbic acid can be obtained from diets. Such diets both provide the essential nutrients required by the body and generally impact the immune system. In this regards, the gut is considered to be the “largest immune organ” since it contains more than 65% of all the body’s immune cells. Dietary immunomodulation techniques focus primarily on immunological proteins of the non-specific immune system that are located in the gut. On this note, increasing people’s understanding of the importance of a balanced nutritional intake is crucial and this review intends to do so. The review further discusses the structural elucidations of the homology of drug and food components, as well as their effects on nutrition and immunology. © The Author(s), under exclusive licence to Springer Nature B.V. 2024.

The RSM results indicate that the highest tensile strength, 41.28 MPa, was achieved at 13.5 wt. % loading and 0.875 µm particle size. The maximum flexural strength of 95.35 MPa occurred at 13.6 wt. % loading and 1.425 µm particle size. Additionally, the greatest impact strength, 5389.12 Joules, was attained with 18 wt. % loading and 1.5 µm particle size. Based on the analysis of the 2 factors interaction model terms, the particle size, weight content, and variables are significant. The R2 = 0.9862; R2Adj = 0.9776; predicted R2 = 0.8936; Adeq Precision = 29.1519. Hence, the RSM models are confirmed to be good predictors of bamboo fiber epoxy composite characteristics for primer components. © 2025

Carrageenan (CGN) is a high molecular weight polysaccharide that is extracted from red seaweeds. It is made up of D-galactose residues connected by β-1,4 and α-1,3 galactose-galactose bonds. As a result of its ability to thicken, emulsify, and stabilize food, it is frequently used as a food additive in processed food. Its consumption has surged in recent years due to the Western diet's (WD) spread. Carrageenan has the ability to change the thickness of the mucus barrier, the composition of the gut microbiota, and the innate immune pathway that causes inflammation. Also, its inherent qualities, which include biodegradability, biocompatibility, resemblance to native glycosaminoglycans, antioxidants, anticancer, immunomodulatory, and anticoagulant activities, Carrageenan-based hydrogels have been the subject of numerous investigations lately for biomedical applications. The brittle hydrogel and uncontrollably exchanged ions, however, are two drawbacks to the application of this polysaccharide, but these can be avoided by making straightforward chemical changes to polymer networks, which create chemically bonded hydrogels with important mechanical characteristics and regulated degradation rates. Furthermore, the addition of diverse kinds of nanoparticles, as well as polymer networks, to carrageenan hydrogels results in hybrid platforms with noteworthy mechanical, chemical, and biological characteristics, which qualify them as appropriate biomaterials for tissue engineering (TE), drug delivery (DD), and also wound healing applications. Our goal in this article is to provide an overview of the most current developments in hybrid carrageenan-based platforms and several chemical modification techniques for TE and DD applications. © 2025 Wiley Periodicals LLC.

When nanotechnology is used in medicine, it makes it easier to find and treat a wide range of diseases. The potentially fatal disease multiple sclerosis (MS) has a disproportionately large impact on young people. One of the oral options for treating this condition is dimethyl fumarate (DMF). This study aimed to use platelet membranes and polymeric nanoparticles (PNs) to develop a drug delivery system that mimics biological cells to treat MS. Here, we produced and characterized solid lipid nanoparticles (SLNs) containing dimethyl fumarate (DMF). To make SLNs, DMF is combined with biocompatible lipids using hot emulsion and ultrasonication techniques. These DMF-SLNs were characterized using transmission electron microscopy (TEM), scanning electron microscopy (SEM), FTIR spectroscopy, and a zeta meter instrument. Characterization revealed that the optimal SLNs had a polydispersity index of (0.28, 0.96, 0.77), a zeta potential of (-22.73 mV,-28.7 mV, and-30.13 mV), and a mean particle size of (562 nm, 1997 nm, and 849 nm). The results of this study suggest that the present formulation may be a potential longer-acting formulation for the improved management of MS. SLNs could significantly change the treatment of many illnesses by providing effective drug delivery. © 2025 by SPC (Sami Publishing Company).

Single and hybrid nanofluids have been widely employed in different thermal systems, showing notable thermal advancements. The current work examines zinc oxide (ZnO) and hybrid multi-wall carbon nanotubes-zinc oxide (MWCNT-ZnO)-based nanofluids to maximize the thermal energy of boilers and assist sustainability. Energetic parameters, such as boiler efficiency and electric power consumption, are also quantified for proposed nanofluids compared to conventional water. Moreover, an enviro-economic analysis was presented to show the CO2 emission minimization and electric energy cost savings on a daily basis. Experimental outcomes revealed that the MWCNT-ZnO hybrid nanofluid has increased the heat transfer rate, convective heat transfer coefficient, and Nu to about 4252 W, 1524 W/m2·K, and 226.19, when at 0.02 % and inlet temperature of 55.94 °C. However, minimum friction factor and pressure drop were reported for water compared to using ZnO and MWCNT-ZnO nanofluids. The hybrid nanofluid augmented boiler efficiency and electric power consumption by about 7 % and 43 %, respectively over water usage, indicating remarkable thermo-energetic progress. Moreover, the enviro-economic analysis results showed that using mono and hybrid nanofluids has decremented CO2 emissions and saved energy costs by about 22 % and 30 % by employing ZnO and MWCNT-ZnO nanofluids, respectively. © 2025 The Author(s)

Biopolymer composites are processed through several methods including infiltration, electrospinning methods and in-situ methods and have achieved considerable global attention been currently utilized in biomedical, automotive, food, construction, and medical industries. Although the efficiency of biopolymer composites has not reached that of their petroleum counterparts, their eco-friendliness, biodegradability, and other qualities will inspire their continual investigation and exploitation. This article focuses on biopolymer composites. It discusses their types, techniques of processing, applications in diverse industries, limitations, and future recommendations. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

Manganese (Mn), an essential trace element, is important in various biochemical and physiological processes such as proper growth and development, digestion, immune response, energy metabolism, homeostasis, reproduction, and defense against oxidative stress through the enzyme manganese superoxide dismutase (MnSOD) in mitochondria of body cells. This review highlights the biological role and effects of manganese on human health as well as health condition associated with manganese. Furthermore, it discusses Mn distribution among people in Nigeria, Ghana and Egypt taking into cognizant the Mn status of food with a view of assessing their health status with respect to Mn. A daily intake of Mn that is insufficient is linked to a number of negative health effects, including reduced fertility, impaired bone formation, generalized growth impairment, and altered lipid, protein and carbohydrate metabolism. However, there are proposed strategy to mitigate Mn induced neurotoxicity. This review reveals there is insufficient data on Mn content of food consumed, drinking water and daily manganese intake of individuals including children in African countries like Nigeria, Ghana and Egypt. Available data reveals most of the popularly consumed food analyzed contains sufficient quantity of Mn and may provide the recommended daily intake (RDI) if the food items are adequately combined in their diet in these regions. Therefore, it is important to emphasize the need to evaluate the Mn content of food consumed, drinking water and daily intake of Mn in Nigeria, Ghana and Egypt. © 2025 Elsevier GmbH

This study investigates the potential corrosion inhibitory effect of 4-methyl-2-(1-aminoethyl)-1,3-thiazole (MAT) on mild steel in a corrosive 1 M HCl solution, utilizing weight loss techniques complemented by Density Functional Theory (DFT) calculations. The inhibition efficiency was found to increase with both the concentration of the inhibitor and the immersion time of the mild steel samples in the HCl solution. At an inhibitor concentration of 0.5 mM and an immersion time of 5 hours at 303 K, the inhibition efficiency reached an impressive 88.5%.

Framed structures recovering efficiently after earthquakes is essential, especially in areas that regularly experience seismic disturbances. This study introduces a network-driven approach to evaluating post-earthquake recovery pathways, moving beyond conventional resilience assessments that rely on predefined recovery functions. By using complex network methodologies, the research models the interactions between structural components and repair sequences, enabling a dynamic assessment of how localized damage impacts overall recovery efficiency. The methodology integrates advanced network theory with structural engineering principles to identify critical nodes and links that influence post-earthquake functionality systematically. By constructing a network representation of the structural system, the study captures cascading failure effects and examines the influence of repair sequences on resilience. Unlike traditional models that often neglect repair order effects, this method explicitly incorporates the sequence of repairs, optimizing recovery paths based on network efficiency metrics. Key parameters such as repair prioritization, resource allocation, and downtime are analyzed to quantify resilience. Case studies on Reinforced Concrete (RC) frames subjected to seismic events highlight the importance of network centrality measures in identifying vulnerabilities and optimizing recovery strategies. The study considers realistic constraints to enhance practical applicability, including resource limitations and varying damage states. While the analysis focuses on planar frames, the methodology can be extended to Three-Dimensional (3D) structures with additional considerations for torsional effects. The findings offer understandings into structural design and post-earthquake decision-making, particularly for engineers and urban planners developing resilience-focused repair strategies. Future work aims to refine the approach by incorporating uncertainties in repair resources and comparing network-driven repair strategies with conventional methodologies. By establishing a structured framework for integrating complex network modeling into resilience assessment, this study advances the understanding of recovery mechanisms in seismic engineering. © 2025

Mild steel (MS) corrosion in acidic environments presents significant challenges due to the limitations of conventional inhibitors, including concerns related to toxicity and environmental impact. This research explores the potential of 2-(2-Aminopropyl)thiazole (APT) as an inhibitor for corrosion of MS in 1 M HCl environment through methodological and DFT combination study. The inhibitory performance of APT reached an impressive efficiency of 88.2 % under optimized conditions (0.5 mM inhibitor concentration, 303 K), demonstrating its promise as an environmentally friendly alternative. Analysis based on Langmuir adsorption isotherm indicated strong and specific interactions between APT molecules and the steel surface, suggesting the formation of a protective film over time. The correlation between inhibition efficiency, immersion time, and temperature revealed a gradual enhancement of the protective effect, with temperature positively influencing the inhibitor's effectiveness, indicative of a thermally activated adsorption process. Calculations of Density Functional Theory (DFT) supported experimental findings and provide insights into molecular interaction at the interface. Just in these case, the calculated theory of electron transfer suggested that the interaction between APT and the atoms of iron was more favorable what shifted the inhibition process in a good direction. This work not only provide important information about the role of corrosion inhibiting but also relies on a reliable methodology that can be genralised to the analysis of eco-friendly corrosive preventing substances. Moreover, the research results provide a basis for the future development of APT for industrial application, which will deal with the real-world problems in the world. Prog.

This study investigates the mechanical properties of carbon and natural fiber-reinforced Polylactic Acid (PLA) and Polyethylene Terephthalate Glycol (PETG) composites produced via Additive Manufacturing (AM), focusing on Material Extrusion (MEX). The performance of filaments made from pre-consumer recycled PLA (rPLA) and PETG, with varying weight percentages of hemp and jute short fibers, was evaluated through tensile testing. Comparisons were made between the original filaments (PLA, carbon fiber-reinforced PLA [CF–PLA], and PETG) and their recycled versions. Multi-material compositions—neat PLA and PETG, single-graded (PLA + CF–PLA, PETG + CF–PETG), and multi-gradient (PLA + CF–PLA + PLA, PETG + CF–PETG + PETG)—were analyzed for mechanical properties. Optical microscope images of multi-material specimens were captured before and after fracture to assess failure mechanisms. The results indicate that the original CF–PETG filaments achieved a tensile strength of 50.14 MPa, which is higher than rPLA, PLA, and CF–PLA by 2%, 70%, and 6.7%, respectively. The re-manufactured PLA filaments reinforced with 7 wt% hemp fibers exhibited a tensile strength of 38.8 MPa, representing a 29% increase compared to the original PLA filaments and a 26% improvement over recycled PLA. Additionally, incorporating 7% jute fiber into PETG resulted in a tensile strength of 62.38 MPa, reflecting a 12% improvement over the original PETG filaments and a 15% increase compared to the recycled PETG filaments. Among specimens produced by AM, CF–PLA and rPLA demonstrated the highest tensile and compressive strengths. However, multi-material composites showed reduced mechanical performance compared to neat PLA and PETG, highlighting the need for improved interlayer adhesion.

In the realm of materials science and corrosion mitigation, the utilization of inhibitors has garnered substantial attention for safeguarding metal assets. This research delves into the proficient utilization of 4-phenyl-1-(phenylsulfonyl)-3-thiosemicarbazide (PP-3-T) as a corrosion inhibitor for mild steel in hydrochloric acid (HCl) solutions, as evaluated through weight loss measurements. The investigation reveals that the incorporation of PP-3-T into the HCl medium engenders a significant enhancement in the corrosion resistance of mild steel, attributed to the formation of a protective barrier via PP-3-T molecule adsorption. A notable finding of this study is the independence of the corrosion inhibition efficiency on variables such as PP-3-T concentration, immersion time, and temperature. The best inhibition efficiency of 96.1% for mild steel immersed in 1 M HCl solution is achieved in the presence of 0.5 mM PP-3-T. Furthermore, the inhibitory effect diminishes significantly as immersion time is extended from 10 to 48 hours at a constant PP-3-T concentration, highlighting the time-sensitive nature of the inhibition process. Alterations in temperature within the range of 303 to 333 K exhibit negligible impact on inhibition efficiency, indicating the robustness of the corrosion protection mechanism. The adsorption isotherm analysis accentuates the adherence of PP-3-T to the Langmuir adsorption model on mild steel, emphasizing the layer formation of the protective barrier. Insights from Density Functional Theory (DFT) quantum chemical calculations reveal critical molecular attributes of PP-3-T governing its corrosion inhibition potential. Parameters such as adsorption energy (ΔE), highest occupied molecular orbital energy (EHOMO), lowest unoccupied molecular orbital energy (ELUMO), energy gap (Egap), as well as chemical reactivity indices encompassing total hardness (η), electronegativity (χ), and electron density transfer (ΔN), elucidate the corrosion inhibition mechanism of PP-3-T. In essence, this comprehensive study unveils the corrosion inhibition efficiency of PP-3-T for mild steel in HCl environments and elucidates the molecular underpinnings that govern its anti-corrosive prowess. These findings contribute to the expanding knowledge base concerning corrosion protection strategies and offer potential avenues for designing novel and efficient corrosion inhibitors. © 2024, Russian Association of Corrosion Engineers.

This research investigates the corrosion inhibition efficacy of 1-mesitylethanone thiosemicarbazone (MTSC), a Schiff base, on mild steel in HCl solution. The study employs weight loss assessment to analyze the corrosion inhibition properties, focusing on the influence of various MTSC concentrations during immersion periods at 303 K. The immersion times considered are 1, 5, 10, 24 and 48 hours. Additionally, the effect of temperature variation (303, 313, 323, and 333 K) on the inhibition efficiency of MTSC is examined. The experimental results reveal an optimal inhibitor concentration of 0.5 mM and an immersion time of 5 hours, where MTSC demonstrates an impressive maximum inhibition efficiency of 93.7%. Furthermore, the CR decreases from 6.62 mg·cm–2·h–1 at 0 mM inhibitor concentration to 0.34 mg·cm–2·h–1 at the optimal concentration, highlighting a significant reduction in corrosion. The concentration-dependent nature of inhibition efficiency is established, with inhibition efficiencies of 75.4%, 83.6%, 89.1% and 92.3% observed at concentrations of 0.1, 0.2, 0.3 and 0.4 mM, respectively. An inverse relationship between inhibition efficiency and temperature is also observed, with inhibition efficiencies of 93.7%, 90.2%, 87.6% and 84.3% recorded at temperatures of 303, 313, 323 and 333 K, respectively. Furthermore, adsorption isotherm analysis indicates conformity to the Langmuir adsorption isotherm. The free energy of adsorption (ΔG0ads) is calculated to be –33.16 kJ·mol–1, providing insights into the adsorption process. In parallel, density functional theory is employed to unravel the inhibition mechanism. The theoretical studies were achieved in the form of the parameters of EHOMO (Highest Occupied Molecular Orbital), ELUMO (Lowest Unoccupied Molecular Orbital), (nucleophilic index), (electronegativity), (chemical potential), and ΔN (the number of electrons transferred). It was observed that the obtained theoretical results are in suitable agreement with the experimental findings. Hence, it provides a complete idea about the corrosion inhibition nature of MTSC. © 2024, Russian Association of Corrosion Engineers. All rights reserved.

Steel corrosion in acidic environments, poses a formidable challenge with conventional inhibitors, often burdened by issues of toxicity, and environmental impact. This study, addresses this challenge, by investigating the suitability of N-piperazinyl-2-furanylketone (NPF) as a green inhibitor for mild steel in 1 M HCl, employing a combined experimental and theoretical approaches. NPF demonstrated an outstanding inhibition efficiency of 93.6% under optimal conditions with an inhibitor concentration of 0.5 mM, at 303 K, showcasing its potential as an environmentally friendly alternative. The efficacy of NPF aligns well with the Langmuir adsorption isotherm indicating a robust and specific interaction between NPF molecules and the steel surface. Further analysis revealed a positive correlation between inhibition efficiency and both immersion time and temperature, suggesting a gradual formation of a protective film on the metal surface. It is worth noting that increasing the temperature enhanced the effectiveness of the tested inhibitor, indicating a thermally activated adsorption process. Theoretical calculations using density functional theory (DFT) supported the experimental results and provided insight into the molecular interactions at the interface. The calculated electron transfer parameter highlighted the positive interaction between NPF and iron atoms enhancing the observed inhibition mechanism. The study, giving the energy of NPF to be green inhibitor corrosion, among others, depicts a very effective method that can be used for evaluating the mechanism and efficacy of these ecofriendly alternatives. Besides synthetic applications studies can also be designed on real world scenarios hence, also capable of optimizing the performances of NPF for bulk industrial productions. © 2024, Russian Association of Corrosion Engineers.

A spectrophotometric determination of azithromycin was optimized using the simplex model. The approach proved to be accurate and sensitive. The analyte reacted with bromothymol blue (BTB) to form a colored ion pair, which was extracted in chloroform in a buffer medium of pH 4 potassium phthalate. The extracted colored product was assayed at 415 nm, exhibiting a linear quantification range of 1-20 µg/mL. The LOD was 0.671 µg/mL, with a correlation coefficient of 0.9998 and an RSD% of 0.96±0.2. The molar absorptivity was 20253.5 L/mol·cm. The excipients did not interfere with the proposed method for assaying azithromycin in curative formulations. © 2024 Malaysian Abstracting and Indexing System. All rights reserved.

When nanotechnology is used in medicine, it makes it easier to find and treat a wide range of diseases. One of the oral options for treating multiple sclerosis (MS) is dimethyl fumarate (DMF). DMF has been shown to be effective in lowering inflammatory diseases; nevertheless, it is characterized by several undesirable side effects that reduce patient compliance and add financial obstacles. The aim of this study was to use platelet membranes and platelet na-noparticles to generate a drug delivery system that works like a cell, so as to treat MS. During the experiments, there is a chance that the DMF solution might harden at room temperature. Therefore, in order to produce solid lipid nano-particles (SLNs), DMF was combined with biocompatible lipids. The creation of SLNs involved the use of hot emulsion and ultrasonication. These DMF-SLNs were characterized by means of scanning electron microscopy, and Fourier-transform infrared spectroscopy. The herein demonstrated enhanced qualities of the devised SLNs suggest that the formulation may be a potential, longer-acting formulation for the improved management of MS. SLNs could change the way many illnesses are treated in a big way, if they are used for the delivery of medicines. © 2024 by the authors.

The Natural Rubber (NR) blend with Styrene-Butadiene Rubber (SBR) loaded with different fraction ratios of NR were prepared. Various ratios of NR namely 25-55 part per hundred rubber part (phr) were prepared. The ratios of SBR ranging 45-75 phr from the masterbatch were blended. The rheological and mechanical properties of pure blends and those loaded with different fraction ratios of NR were investigated. Rheological properties analysis has been showing improvement in most blend ratio until 40 phr NR. Parameters such as initial, minimum and maximum torques, Mooney viscosity, and thermo-plasticity were recorded. The overall enhancement is observed in cure rate and induction time in relation with NR loading up to 50phr NR, then declined in above this ratio. The mechanical properties, namely hardness, tensile strength, and Young modulus were improved as NR content increases to nearly 40 phr NR while elongation improved by 35% only. The young modulus results show random behaviour and the maximum value was at the content of 40-45 phr NR. Accordingly, the 40 phr NR blend was found to exhibit the highest values of the most rheological and mechanical properties. © 2023 Author(s).

Maintenance in Iraqi oil and gas (O&G) firms is critical in providing customers with operations, maintenance, and services for O&G products. In recent decades, fresh theories for enhancing the performance of the oil and gas business, such as lean management and six sigma, have emerged. The lean management concept is used in this study to improve services and maintenance in the Iraqi O&G industry. A quantitative technique was used to reach the study's aim, including a questionnaire that was produced and sent electronically. The assessment was undertaken at the Najaf refinery in southern Iraq and the A-Dora refinery in the centre of Iraq. It was discovered that finding value in lean management plays no significant effect on maintenance performance in the Iraqi O&G industry. Furthermore, it was discovered that the map value stream greatly influences maintenance performance and that establishing flow in lean management has no substantial impact on maintenance performance in the O&G business. Furthermore, the data showed that establishing pull has no substantial impact on the O&G industry's maintenance performance and that chasing perfection has no significant impact on maintenance performance. The researcher made several recommendations and future work proposals to increase O&G maintenance performance. © 2023 Taylor's University. All rights reserved.
