Published: February 2025

Poultry farming, especially domestic fowl (Gallus-gallus domesticus), is a crucial agricultural activity worldwide, providing an affordable and reliable source of protein through eggs and meat. Despite its importance, gastrointestinal parasitism remains a major challenge, significantly compromising poultry health and productivity. This study investigated the prevalence and species composition of gastrointestinal parasites in domestic chickens from four tehsils of district Buner, Khyber Pakhtunkhwa, Pakistan, from August 2022 to August 2023. A total of 400 fecal samples were analyzed at the Veterinary Research and Disease Investigation Center, Balogram, Swat. The findings revealed a high prevalence of oocysts from Eimeria species, with Eimeria tenella (69.25%) and Eimeria brunetti (61%) being the most common. Additionally, Eimeria maxima (59.75%), Dispharynx nasuta (41.75%), Ascaridia dissimilas (54.75%), Capillaria annulata (57.5%), and Capillaria contorta (56.5%) were detected. Parasitic worms, including Raillietina tetragona (51.25%), Davainea proglottina (56.25%), and Ascaridia galli (59.5%), were also prevalent. Unidentified oocysts were observed, suggesting the presence of potentially novel parasite species. This study highlights the widespread burden of gastrointestinal parasites in poultry in the region, underscoring the need for enhanced control measures and further research into parasite management strategies to improve poultry health and productivity.

D’ici à 2050 il sera nécessaire de nourrir 9,7 milliards de personnes à travers le monde. Cela constitue l’un des principaux défis de développement durable, définis par l’organisation des Nations Unies pour l’alimentation et l’agriculture, la Food and Agriculture Organization [1]. Celle-ci considère alors pour l’avenir l’aquaculture comme une bonne stratégie pour fournir à la population mondiale des sources de protéines de qualité, comme c’est déjà le cas aujourd’hui avec près de 50 % du poisson consommé dans le monde provenant de l’élevage. Cependant, pour soutenir l’augmentation de la population globale, et donc la production de poisson pour la consommation humaine, beaucoup d’efforts doivent encore être faits dans le domaine de l’aquaculture, en particulier en Europe. Les activités d’élevage de poissons y stagnent depuis de nombreuses années autour de 17 %, alors même que la production aquacole mondiale a été multipliée par quatre depuis les années 1990, et ne cesse encore de croître.
Des glucides pour nos truites ? Zoom sur une alternative à la farine de poisson
Authors: Marandel Lucie , Besombes Julie , Baert Simon , Nappey Fabien
Published: February 2025

Les végétaux terrestres produits en France, et plus largement en Europe, sont de bons candidats de substitution à la farine de poisson. En effet, ils sont produits en abondance et à coût compétitif sous nos climats. Ces plantes, comme le blé par exemple, semblent particulièrement intéressantes d’un point de vue économique par leur grande teneur en glucides digestibles avec une valeur nutritionnelle, tels l’amidon et les glucides simples. Ces éléments, dits macronutriments en raison de leur apport indispensable à la nutrition, constituent la source énergétique la plus abondante et la moins onéreuse de tous les aliments destinés à l’élevage du bétail. Leur incorporation dans ceux destinés aux poissons carnivores, comme la truite arc-en-ciel, pourrait permettre d’augmenter la rentabilité des fermes aquacoles en diminuant le coût lié à l’alimentation. Le fait que cette dernière soit produite localement, réduisant ainsi le transport de ces matières premières, est un autre avantage.

Authors: Avetisyan Gagik
Published: February 2025

The formation of artistic perceptibility in the process of mastering innovation technologies is of theoretical and practical importance for improving the effectiveness of aesthetic education and artistic training of students, the development of their emotional and intellectual spheres. The conducted research has yielded results that can be considered as scientific and theoretical tasks and conditions that contribute to the formation of students’ artistic receptivity in the field of innovation technology.
However, in the process of studying innovation technology, its educational impact is only if the student not only correctly perceives the available innovation, but also empathizes with the semantic content of this work, perceives it through the prism of his own experience, objectively evaluates and creatively compares this work with reality and new methods. Teaching students innovation methods should be aimed, first of all, at mastering the experience of perceiving new technologies, which is basic in nature, corresponding to the needs of students.
From our point of view, the prospects for the development of problems of the formation of artistic perceptibility of students are associated with the study of future opportunities and the application of features of traditional methods, as well as with the creation of new methods of teaching and educational work of students in the field of innovative technologies.
Bioquímica de la intoxicación metanólica
Authors: Varela Rodelo Francisca
Published: February 2025

El metanol, igual que las sustancias volátiles que son metabolizadas lentamente, tienen un metabolismo y excreción complejos, razón por la cual el metabolismo del metanol se estudia "in vivo", midiendo la cantidad de dióxido de carbono -C " formado a partir del metanol -C ".El formaldehido es el primer metabolito que se produce en la intoxicación por metanol, por acción de la actividad oxidante de la catalasa, en presencia de un generador de peróxido de hidrógeno, como la glucosa oxidasa, bajo la forma de complejo I, catalasa- peróxido. El formaldehido se combina con algunos grupos funcionales de las proteínas, modificando las propiedades estructurales de ellas.El tungstato de sodio disminuye la actividad de la xantina oxidasa, enzima generadora de peróxido, y por ende el grado de oxidación de la catalasa para transformar el metanol en formaldehido. La alcohol deshidrogenasa hepática (ADH), cataliza la oxidación del metanol a formaldehido y de otros alcoholes alifáticos. La afinidad de los alcoholes alifáticos de cadena recta, por la ADH, aumenta cuando aumenta el peso molecular del alcohol. El piparzol inhibe casi inmediatamente el metabolismo del metanol "in vivo", inhibiendo la alcohol deshidrogenasa hepática, formando un complejo ternario de PIPARZOL- NAD- ADH. El formaldehido se metaboliza por acción de la formaldehido deshidrogenasa; esta enzima activada es indispensable para reducir el glutation (G S H), y participa en su mecanismo catalítico, demostrándose que el formiato se forma enzimáticamente, y un mol de N A D es reducido por cada mol de formiato formado; en esta reacción se forma un tiohemiacetal el cual sirve de substrato para la enzima.
ADSORPTION OF β-CAROTENE FROM VEGETABLE OIL ON PILLARED MODIFICATIONS OF MONTMORILLONITE
Authors: Butman Mikhail F. , Ovchinnikov Nikolay L. , Yashin Dmitry V.
Published: February 2025

This work investigates the efficiency of adsorptive refining of vegetable oil, evaluated by β-carotene adsorption, using different forms of synthesized pillared montmorillonite (PMM) obtained by intercalation of large-sized hydroxocomplexes [Аl13О4(ОН)24(Н2О)12]7+, [Al30O8(OH)56(H2O)24]18+, as well as complexes - products of aluminium and cerium co-hydrolysis. Pillaring is considered as an alternative to acid activation of montmorillonite for oil bleaching. The periodic pillar structure of PMM provides a developed specific surface area and regular distribution of mesopores, as well as the presence of active centres of different nature. The textural characteristics of the original montmorillonite and its pillar modifications were measured using nitrogen adsorption-desorption method. The textural feature of Al30-PMM is the maximum pore space volume (0.173 cm3/g), while Al/Ce-PMM has the maximum value of specific surface area (154 m²/g) and the minimum average pore diameter (5.6 nm). Kinetic curves of β-carotene adsorption at temperatures of 20, 40, 60 and 90 °C at a dosage of 1 g of adsorbent per 20 ml of oil were obtained using the photometry method. It was found that for all temperatures there is a tendency of increase of sorption capacity in the series: montmorillonite (MM), Al13-PMM, Al30-PMM, Al/Ce-PMM, which correlates with the increase in the value of specific surface area of the adsorbent in this series. Increasing the temperature from 20 to 90 °C leads to an increase in bleaching efficiency of up to 20 per cent. The kinetics of the sorption process is described by pseudo-first and pseudo-second order kinetic models. From the temperature dependences of the equilibrium constants, the enthalpies of β-carotene adsorption were obtained, monotonically increasing in the MM, Al13-PMM, Al30-PMM, Al/Ce-PMM series. Their values (5.6-22.3 kJ mol-1) indicate the physical nature of adsorption.

HUMAN DEVELOPMENT INDEX, CIRCULARITY INTERRELATION AND ECONOMIC SUSTAINABILITY
Authors: Mu'awwanah Uliyatul , Nani Hanifah
Published: February 2025

The transition to a developed country requires action and policy. In government practice, its transition can be strategized generally by setting targets. So far, the Human Development Index does not have a specific achievement target due to the indicators measurement which are still rare to use. To bridge this gap, this paper focuses on studying which targets can facilitate the transition to a developed country by maximizing human development measurement tools. This analysis focuses on previous and updated tools (recommendations); this approach aims to complete the previous tools which are limited to some indicators that only cover part of the development sustainability goals. A framework based on HDI, circular economy, and sustainable investment. This study clarifies that existing human development targets do not necessarily support sustainable development, even though they are the most commonly implemented targets recently. In the case of a lack of measuring tools effectiveness whether on integrating education through knowledge quality, the existence of waste banks as a response to a circular economy and investment sustainability needs to be reconsidered. Furthermore, this study explores the HDI published by the Center of Statistics Agency which has examined and published the human development condition. Specifically, this study aims to expanding a new indicator series to be included to human development success rate measurable variables emphasizing on the circular economy and a new view on investment sustainability and is intended for academics and policy-makers.

Authors: Fachrurrosi Harie , Sucipto Imam
Published: February 2025

This research discusses the concepts of ‘Aam (general), Khas (special), Amr (command), and Nahy (prohibition) in ushul fiqh, focusing on the relevance of their application in the study of Islamic law. These concepts play an important role in understanding the shar'i propositions, especially the Qur'an and Hadith. This research uses a qualitative analysis method by reviewing primary and secondary sources in ushul fiqh literature. The results show that ‘Aam and Khas help establish the scope of the law, while Amr and Nahy serve as the basis in determining the obligation or prohibition of an action. The study also found that the application of these four concepts is highly contextualised, thus requiring a deep understanding of the nashas and the situation at hand. This research is expected to provide clearer insights in applying the principles of ushul fiqh in fatwas and contemporary ijtihad.

Published: February 2025

Nanoparticle synthesis is gaining tremendous attention of researcher now a days. Due to high energy requirements and environmental risks associated with physical and chemical techniques, the utilization of plant sources has become imperative for the fabrication of nanoparticles. In this study, we report the silver nanoparticles (AgNPs) fabricating potential of aqueous leaf extract of Mentha sylvestris without any additional caping or stabilizing agent in an eco-friendly and cost-effective manner. The bio-reduction of AgNPs was indicated by color change of silver nitrate solution. The synthesized AgNPs were characterized by UV-visible spectrometry, scanning electron microscopy (SEM), Energy dispersive x-ray spectroscopy (EDX)and X-ray diffraction (XRD) analysis. UV-visible spectral analysis revealed absorption peak at 453 nm for AgNPs. Flame Atomic Absorption Spectroscopy (FAAS) determined the reduction rate of ionic silver in solution.  X-ray diffraction (XRD) analysis confirmed the average crystalline size. AgNPs ranged in size from16.2-56.4 nm with average size of 33.38 nm. SEM analysis showed the morphology of AgNPs which is found to be spherical, rectangular to variable shapes. Energy dispersive X-ray analysis evidenced the presence of elemental silver hence further confirmed green synthesis. Present study concludes that M. sylvestris species have great potential to bio-fabricate AgNPs in rapid and facetious way.

Published: February 2025

Instructional media play a vital role in enhancing the quality of teaching and learning, yet inadequate and outdated learning materials remain a significant challenge in Nigeria's educational system. To address this issue, a study was conducted in Bauchi metropolis, focusing on the development of a video tutorial as an instructional medium for teaching tie and dye in secondary schools. The study aimed to identify current instructional media used in teaching Dyeing and Bleaching, develop a video tutorial for teaching tie and dye skills, and test the efficacy of the developed instructional media. A pilot study was conducted in ten secondary schools to identify the instructional media currently utilized in teaching Dyeing and Bleaching and Fine Arts. Using an applied research design, a video tutorial was developed for teaching tie and dye procedures, incorporating visual, audio, and textual elements using Canva graphics. The efficacy of the developed instructional media was tested on 102 respondents from four secondary schools in Bauchi metropolis using quantitative methods, including structural objective test questions and tie and dye practical tests. Results revealed that respondents could watch the tie and dye video tutorial and replicate tie and dye patterns independently, even without teacher guidance. Additionally, those who struggled to grasp the theory could perform well with the aid of the video tutorial. The study demonstrated that instructional media significantly influenced tie and dye learning, contributing to 65% of the variability in enhancing tie and dye practical learning. Based on the findings, several recommendations were proposed to improve tie and dye teaching and learning, including visual demonstrations, interactive tutorials, improvisation, printable resources, and case studies and examples.

Globalization and migration(s) – a view from Southeast Europe
Authors: Atanasov Petar
Published: February 2025

Migration as a quest for better living is a never-ending phenomenon, and millions of migrants, even today, are still on their way to the more developed parts of the world. On the one hand, the question arises whether the phenomenon seems to be slowly changing its former characteristics in the era of the latest globalization processes. On the other hand, migrations for a long time used to be heading from the South to the North and from the East to the West, at least for the last couple of centuries, something that is not the only case anymore. In this paper, the main goal is to analyze: first, the current process and what is new about globalization; second, the latest phenomena of migrations and the individualization of migration; third, the connectedness and interdependence between the two categories, including some of the gains and losses; and fourth, shed more light on migration in Southeast Europe and consequences for the migrant-sending and migrant-receiving countries.

The hippocampus is a complex structure critically involved in numerous behavior-regulating systems. In young adults, multiple overlapping spatial modes along its longitudinal and transverse axes describe the organization of its functional integration with neocortex, extending the traditional framework emphasizing functional differences between sharply segregated hippocampal subregions. Yet, it remains unknown whether these modes (i.e., gradients) persist across the adult human lifespan, and relate to memory and molecular markers associated with brain function and cognition. In two independent samples, we demonstrate that the principal anteroposterior and second-order, mid-to-anterior/posterior hippocampal modes of neocortical functional connectivity, representing distinct dimensions of macroscale cortical organization, manifest across the adult lifespan. Specifically, individual differences in topography of the second-order gradient predicted episodic memory and mirrored dopamine D1 receptor distribution, capturing shared functional and molecular organization. Older age was associated with less distinct transitions along gradients (i.e., increased functional homogeneity). Importantly, a youth-like gradient profile predicted preserved episodic memory – emphasizing age-related gradient dedifferentiation as a marker of cognitive decline. Our results underscore a critical role of mapping multidimensional hippocampal organization in understanding the neural circuits that support memory across the adult lifespan.
Genetic Inactivation of the β1 adrenergic receptor prevents Cerebral Cavernous Malformations in zebrafish

Published: February 2025

Propranolol reduces experimental murine cerebral cavernous malformations (CCMs) and prevents embryonic caudal venous plexus (CVP) lesions in zebrafish that follow mosaic inactivation of
ccm2
. Because morpholino silencing of the β1 adrenergic receptor (
adrb1
) prevents the embryonic CVP lesion, we proposed that
adrb1
plays a role in CCM pathogenesis. Here we report that

adrb1
−/-

zebrafish exhibited 86% fewer CVP lesions and 87% reduction of CCM lesion volume relative to wild type brood mates at 2dpf and 8-10 weeks stage, respectively. Treatment with metoprolol, a β1 selective antagonist, yielded a similar reduction in CCM lesion volume.

Adrb1
−/-

zebrafish embryos exhibited reduced heart rate and contractility and reduced CVP blood flow. Similarly, slowing the heart and eliminating the blood flow in CVP by administration of 2,3-BDM suppressed the CVP lesion. In sum, our findings provide genetic and pharmacological evidence that the therapeutic effect of propranolol on CCM is achieved through β1 receptor antagonism.

Novel 3D printed universal conical holder for eye plaque quality assurance
Authors: Wang Wentao , Emrich Jacqueline , Mourtada Firas
Published: May 2024

Purpose

For the custom‐built construction of eye plaques, the iodine (I‐125) seeds of different source strengths are recycled in our eye plaque program. To return I‐125 seeds to the correct lot, we developed a novel 3D‐printed conical plaque QA holder for relative assay for eye plaques.

Materials and methods

A universal 3D‐printed conical plaque holder was designed to accommodate six plaque sizes and fit reproducibly in a well‐type dose calibrator. A reproducibility test was used to compare the plaque placement consistency in the holder versus without the holder. Plaque assays were performed for assembled plaques both before implant and after explant. The explant reading was compared with the implant reading adjusted for decay, and the relative error was calculated. The plaque response fraction (PRF) is defined as the fraction of well chamber implant reading over the total seed strength for a plaque. The PRF was aggregated for each individual plaque to confirm the seed lot before implant.

Results

The reproducibility test showed the chamber reading's relative standard deviation of 0.40% with the QA holder compared to 0.68% without it. The batch relative assay was performed for 251 plaques. The absolute value of measurement deviation between explant and decay‐corrected implant readings is 0.89% ± 0.86% (mean ± standard deviation). The PRFs for individual plaques range from 36.49% to 49.87%, with a maximum standard deviation of 2%.

Conclusions

This novel 3D‐printed QA holder provides reproducible setup for assaying assembled eye plaques in a well chamber. Batch relative assay can validate the seed batch used and plaque integrity during the implant without assaying individual seeds, saving valuable physicist time and radiation exposure from seed handling.

Objective

Positive antineutrophil cytoplasmic antibodies (ANCAs) may occur in the setting of interstitial lung disease (ILD), with or without ANCA‐associated vasculitis (AAV). We aim to compare the characteristics and clinical course of patients with ILD and positive ANCA (ANCA‐ILD) to those with negative ANCA.

Methods

We performed a single‐center retrospective cohort study from 2018 to 2021. All patients with ILD and ANCA testing were included. Patient characteristics (symptoms, dyspnea scale, and systemic AAV), test results (pulmonary high‐resolution computed tomography and pulmonary function tests), and adverse events were collected from electronic medical records. Descriptive statistics and the Fisher exact test were used to compare the outcomes of patients with ANCA‐ILD to those with ILD and negative ANCA.

Results

A total of 265 patients with ILD were included. The mean follow‐up duration was 69.3 months, 26 patients (9.8%) were ANCA positive, and 69.2% of those with ANCA‐ILD had another autoantibody. AAV occurred in 17 patients (65.4%) with ANCA‐ILD. In 29.4% of patients, AAV developed following ILD diagnosis. Usual interstitial pneumonia was the most common radiologic pattern in patients with ANCA‐ILD. There was no association between ANCA status and the evolution of dyspnea, diffusing capacity of the lungs for carbon monoxide, and lung imaging. Forced vital capacity improved over time in 42% of patients with ANCA‐ILD and in 17% of patients with negative ANCA (P = 0.006). Hospitalization occurred in 46.2% of patients with ANCA‐ILD and in 21.8% of patients with negative ANCA (P = 0.006). Both groups had similar mortality rates.

Conclusion

Routine ANCA testing should be considered in patients with ILD. Patients with ANCA‐ILD are at risk for AAV. More research is required to better understand and manage patients with ANCA‐ILD.

Published: May 2024

The introduction of metallic nanoparticles (NPs) has revolutionized the fabrication of flexible electronic devices. Metallic NPs have numerous applications in the electronics industry due to their unique shape and size‐dependent properties compared to their bulk counterparts. However, the application of metallic NPs requires additional post‐processing procedures to remove stabilizing agents and additives, to achieve superior electrical conductivity. Herein, the sintering of printed metal NP patterns, including silver (Ag) and copper (Cu) NPs, fabricated on flexible polyimide substrates is explored using single and dual sintering methods. The single sintering methods involve exposing the printed metal NPs to either laser irradiation or thermal treatment. In the case of the dual sintering methods, one approach is to subject the printed metal patterns to thermal treatment followed by laser irradiation, while the other approach involves exposing the printed metal patterns to laser irradiation followed by thermal treatment. Moreover, this study identifies and compares the effects of these various sintering methods on the physical, electrical, chemical, and mechanical properties of the Ag and Cu NP patterns. Finally, the study suggests that dual sintering methods are more effective in improving the electrical conductivity and mechanical properties of the NP patterns under optimized sintering conditions.

Hybrid organometal halide perovskites (HP) present exceptional optoelectronic properties, but their poor long‐term stability is a major bottleneck for their commercialization. Herein, a solvent‐free approach to growing single‐crystal organic nanowires (ONW) is presented, along with nanoporous metal oxide scaffolds and HP, to form a core@multishell architecture. The synthesis is carried out under mild vacuum conditions employing thermal evaporation for the metal‐free phthalocyanine (H2Pc) nanowires, which are the core, plasma‐enhanced chemical vapor deposition (PECVD) for the TiO2 shell, and co‐evaporation of lead iodide (PbI2) and methylammonium iodide (CH3NH3I/MAI) for the CH3NH3PbI3 (MAPbI3/MAPI) perovskite shell. A detailed characterization of the nanostructures by electron microscopy, (S)‐TEM, and X‐ray diffraction, XRD, is presented, revealing a different crystallization of the HP depending on the template: while the growth on H2Pc nanowires induces the typical MAPI tetragonal structure, a low‐dimensional phase (LDP) is observed on the 1D‐TiO2 nanotubes. Such a combination yields an unprecedentedly stable photoluminescence emission over 20 h and over 300 h after encapsulation in polymethyl methacrylate (PMMA) under different atmospheres including N2, air, and high moisture levels. Moreover, the unique 1D morphology of the system, together with the high refractive index, allows for a strong waveguiding effect along the HP nanowire length.

In this critical review, the attempt is to overview the current comprehension regarding the electrolyte solvation structure in zinc battery technology. Advanced methodology toward the interactions between zinc cations, solvent molecules, and anions in zinc aqueous electrolytes and the general rules for electrolyte design from the atomic level are summarized. Methods for viable solvation modification are then introduced regarding overcoming the remained challenges for transferring the laboratory results to next‐generation practical applications. Possible research direction with the aim of investigating the ultimate choice for future high‐performance electrolyte solvation construction is also outlined.

Plasmonic nanomaterials with multiple components and designed structures show diverse properties and functions owing to the synergistic effects of the different components. Engineering the compositional and structural complexity of plasmonic nanomaterials is a powerful technique for expanding their range of applications. A facile approach to an unprecedented dart‐like type of nanostructure with AgPd bimetal selectively deposited at one end of Au nanobipyramids, forming AgPd nanodarts, is reported here. The synthetic process involves both galvanic replacement and Ostwald ripening. The morphological evolution of the AgPd nanodarts is thoroughly investigated and the growth mechanism is put forward. The as‐obtained AgPd nanodarts exhibit an outstanding photothermal conversion efficiency and peroxidase activity, which make them powerful for photothermally–catalytically combined tumor organoid ablation. In addition, two types of AgPd nanodart‐derived single‐end nanostructures, AgPd@ZIF‐8, and AgPd@TiO2 nanodarts, are prepared for the first time. The ZIF‐8 and TiO2 shell are preferentially coated at the AgPd end of the AgPd nanodarts, respectively. Both AgPd@ZIF‐8 and AgPd@TiO2 nanodarts show superior antimicrobial activities. The protocol and concept of modulating the structure of the nanodarts in this work can be extended to the development of a new class of plasmonic nanostructures with multifunctionalities.

Single‐crystal metal foils with high‐index facets are currently being investigated owing to their potential application in the epitaxial growth of high‐quality van der Waals film materials, electrochemical catalysis, gas sensing, and other fields. However, the controllable synthesis of large single‐crystal metal foils with high‐index facets remains a great challenge because high‐index facets with high surface energy are not preferentially formed thermodynamically and kinetically. Herein, single‐crystal nickel foils with a series of high‐index facets are efficiently prepared by applying prestrain energy engineering technique, with the largest single‐crystal foil exceeding 5×8 cm2 in size. In terms of thermodynamics, the internal mechanism of prestrain regulation on the formation of high‐index facets is proposed. Molecular dynamics simulation is utilized to replicate and explain the phenomenon of multiple crystallographic orientations resulting from prestrain regulation. Additionally, large‐sized and high‐quality graphite films are successfully fabricated on single‐crystal Ni(012) foils. Compared to the polycrystalline nickel, the graphite/single‐crystal Ni(012) foil composites show more than five‐fold increase in thermal conductivity, thereby showing great potential applications in thermal management. This study hence presents a novel approach for the preparation of single‐crystal nickel foils with high‐index facets, which is beneficial for the epitaxial growth of certain two‐dimensional materials.
