ABSTRACTObjectiveYoung adults with spina bifida (and other congenital neurologic diseases) have their own aspirations that may include education, employment, relationships and having children. As they move from pediatric to adult care, they must eventually transition to an adult healthcare team. The objective of this paper is to review the challenges and controversies in the transitional and adult care of people with congenital neurourological diseases.MethodsThe Research Group convened a meeting of its members and invited guests to better understand the healthcare challenges faced by these patients as they become adults. The group examined potential research opportunities focused on people with these diagnoses and themes related to their healthcare.ResultsTrust and clear communication are essential for effective patient transition. Ideally parents are involved in the transition to help reinforce independent self‐care and responsibility. Adolescents require education about sexual health and independence, which may not be part of the core skillset of a urologist. The healthcare team must promote self‐management and autonomy as early as practical. One of the major limitations is that adult care lacks the coordination of pediatric care, and patients may not have a “medical home.” Multidisciplinary clinics are ideal but face logistical barriers in adult medicine. Additional barriers include limited physicians with the required specialized training. In the adult system, financial constraints are a key challenge for patients and providers.ConclusionCollaboration, supported by institutions and new research, is vital for improving the neurourological care of young adults with complex diseases.Trial RegistrationThis study reports on the proceedings of a meeting, and therefore clinical trial registration was not necessary.

ABSTRACTIntroductionOne of the main causes of a neurogenic bladder is spinal cord injury (SCI),(SCI), which induces little or no bladder reflex activity. Because of this alteration, there is an increased risk of developing urinary tract infections and kidney damage. Gonadotropin‐releasing hormone (GnRH) treatment has been shown to improve micturition in a rat model of SCI.AimThe present study was aimed at determining whether GnRH administration is capable to reduce bladder and kidney damage in rats with SCI.MethodsOvariectomized female Wistar rats were divided into three groups: sham, SCI with saline solution (SCI), and SCI treated with GnRH (SCI+GnRH) for 6 weeks. SCI was induced by compression at the T10 spinal level. At the end of the experiment, bladders and kidneys were processed for morphological and immunofluorescence analysis. For morphometric analysis, the thickness of the urothelium and the muscular layer of the bladder was measured, as well as the intensity of staining related to collagen in the kidney.ResultsAt the end of the experiment, all animals in the sham group showed normal urination (100%), in contrast, the percentage of untreated injured rats (SCI) that did not require manual stimulation for micturition was 19%, while the treated group (SCI+GnRH) was 68%. A significative increase in bladder weight, urothelial and muscle thickness, and collagen‐related coloration in the kidney was observed in SCI when compared to sham rats.ConclusionGnRH administration decreased damage to the urinary bladder and kidneys after SCI in rats. These results suggest that this hormone could be a potential preventive treatment for SCI patients at risk of neurogenic bladder and kidney damage.Trial RegistrationNot applicable.

Authors: Nizinkovskyi Rostyslav , Naumenko Konstantin , Krüger Manja 
Published: September 2024

AbstractDespite the development of three‐dimensional imaging techniques in materials science, most of the microstructural data is taken from two‐dimensional sections. It includes images produced by optical, scanning, and transmission electron microscopy. Due to the stochastic indefinite characteristics of such sections, it is a challenge to reproduce three‐dimensional microstructure characteristics quantitatively. Several analytical techniques were developed in stereology to overcome such limitations. Nevertheless, available analytical techniques are restricted to limiting cases of entirely random or fully coaxial orientation of microstructural features. On the other hand, achieving ideal coaxiality of such inclusions in actual technological conditions is not achievable. In this work, the Monte‐Carlo‐based optimization algorithm is constructed to overcome the limitations of existing stereometric models. This algorithm considers information from longitudinal and transverse sets of images. Orientations, as well as size distributions, are taken into account. The model operates under the assumption of log‐normal distribution of 3d size characteristics and von Mises distributions of angles. Then, a derivation‐free optimization algorithm is used to match histograms of simulated and observed sections. The method for estimating the initial values of optimized variables is proposed, based on the existing analytic solutions. The reconstruction algorithm is then applied to estimate three‐dimensional angle and size distributions of inclusion of phase in near‐eutectic alloy, produced by directional solidification technique. Finally, the algorithm's convergence is discussed, as well as its limitations and future developments.
Advanced Computational Insights Into the Optical, Electronic, and Thermoelectric Characteristics of Novel Rare‐Earth Ternary Chalcogenides
Authors: Mohamed Abdelhay Salah , Abbas Faheem 
Published: September 2024

ABSTRACTRare‐earth ternary materials are distinguished by their tunable optoelectronic characteristics and high thermal stability. First principles computations examine the intricate interaction of novel rare‐earth‐based ternary chalcogenide's electronic, optical, and thermoelectric properties. The spin‐down channel of PrHSe exhibits a substantial energy gap resulting in half‐metallic behavior. The f orbitals of Pr and Er play an important role in forming bonds with Se and H atoms, contributing significantly to the valence band. The preponderance of Pr‐f and Er‐f orbitals near the top of the valence band indicate that electrons in these orbitals are the most energetic and participate in bonding interactions within these materials. The ErHSe has a greater absorption rate than PrHSe, and both materials behave isotropically in the xx and zz directions. The highest peaks of the reflection coefficient (50%–70%) in the 1.0–13.8 eV range suggested a significant level of UV reflectivity. The PrHSe has a higher intrinsic carrier concentration for conduction than ErHSe. At lower temperatures, carrier concentrations increase due to thermal activation processes, improving the Seebeck coefficient in these materials.

AbstractOrganic dyes derived from industrial processes have harmful potential to aquatic systems and require novel oxidative treatment. Metal‐organic frameworks (MOF) couple high adsorption capacity and photocatalytic action, which can be improved through heterojunctions. In this work, CuBTC (MOF) photocatalyst was synthesized by an electrochemical methodology, and the in situ CuS templated formation by addition of Na2S solution, giving CuBTC/CuS composites. The synthesized CuBTC MOF and CuBTC/CuS composites were characterized by XRD, FTIR, TGA, and EDX. The adsorptive capacity and photocatalytic properties were evaluated by the photocatalytic performance against methylene blue (MB) aqueous solution, under dark and simulated solar irradiation. Under simulated solar irradiation, the CuBTC/CuS achieved 87 % dye photodegradation after 120 min, 1.7 times higher than CuBTC. The photocatalytic action mechanisms were investigated by free‐radical capture experiments. At the equilibrium, the photocatalytic process presented pseudo‐first‐order (PFO) and pseudo‐second‐order (PSO) non‐linear kinetic models, showing a higher correlation with the PFO model, with a rate constant of 94.3×10−3 min−1. The photocatalytic performance of the composite was also evaluated over five cycles, decreasing to 68 %. The proposed strategy showed promise for the developing of highly effective materials to combat water pollution.

AbstractAn efficient I2 (10 mmol %)/H2O2 mediated oxidative formal [4+1] cyclization of 2‐pyridinemethylamine or o‐phenylenediamine (2‐aminobenzenethiol) with benzaldehyde via C−N bond formation has been developed. This strategy provides a straightforward approach to imidazo[1,5‐a]pyridines, iodo‐substituted imidazo[1,5‐a]pyridines and benzimidazole (benzothiazole) derivatives in yields ranging from 60 % to 98 %, respectively. Several heterocyclic products exhibit promising blue luminous performance with satisfactory fluorescence quantum yields of up to 64 %, large Stokes shifts, and a longer lifetime (7.35 ns). The band gap energies obtained from DFT are also consistent with the absorption spectra.

Published: September 2024

AbstractIn view of the importance of metal coatings, this study addresses the ion concentration of the anti‐corrosive coating's immersion solution. The physical properties of the coating surface, such as molecular characteristics, smoothness, and structural strength, were changed by adding nano‐SiO2 in the immersion solution to formulate the best scheme for anti‐corrosive performance. The composite coating was prepared on the surface of AZ31B magnesium alloy by electroless plating. Besides, the surface coating based on AZ31B substrate has high‐quality corrosion resistance to different types of contaminated media. The experimental results demonstrate that the nanocomposite coating can form an ultrafine particle‐filling effect on the metal surface, which is lower than the drag force of the conventional metal surface. Considering the slip velocity gradient in the contact coating area, we reduce the shear stress and drag force, verifying the nanocomposite coating's effect on reducing the reaction force. The contact angle of water droplets in the composite coating is greater than 158.7°. The study finally verifies that the prepared coating has good self‐cleaning potential which can prevent the corrosion of different polluted media.
Selective Cleavage and Structural Stability of Double Crosslinked Aromatic Polyamide Porous Materials
Authors: Yoshioka Yayoi 
Published: September 2024

AbstractA porous, crosslinked aromatic polyamide having COCl and COOH groups (referred to as PA herein) prepared had a mesoporous structure and comprised agglomerates of particles with average diameters of approximately 30 nm. The PA was found to swell with significant deformation in response to water vapor, but was almost unchanged after exposure to toluene vapor. The polymeric structure returned to its original porous morphology after removal of the solvents, demonstrating that the PA possessed affinity for specific solvents and shape memory. The chemical composition and porous structure of the PA were also not affected by heating to 330 °C. The COCl groups in the PA could be modified by reaction with 2,4,6‐triaminopyrimidine (TAP), resulting in a doubly crosslinked structure based on the reaction with the TAP as well as the existing amide moieties in the polymer. The degree of modification was highly dependent on the reaction solvent used. The porous structure of the PA was essentially unchanged after this modification. The TAP‐based crosslinks in the modified PA could be selectively cleaved along with vaporization of the TAP by heating at 330 °C, which no change to the porous structure. Thus, the PA showed excellent heat resistance and structural stability.

AbstractCarbonatite bearing rare earth elements are rich sources of rare earth elements and play a critical role in the global supply chain. While carbonatite deposits are less accessible compared to ion adsorption clays, their mineral composition makes them essential for rare earth element extraction. Extraction of rare earth elements from carbonatite ore involves acid leaching, a process that we aim to explore in this study using the carbonatite ore from Lugiin gol. Characterization of the raw material and solid residue post‐leaching was conducted using X‐ray diffractometry, inductively coupled plasma optical emission spectroscopy, and a zeta potential analyzer. These analytical techniques were utilized for kinetic modeling, assessing the influencing factors of leaching, and determining metal recovery in the pregnant solution. The results of the study highlight the significant role of surface charge formation on target particles during milling in the acidic leaching process. This finding shed light on the importance of understanding the surface properties of the particles in the extraction of rare earth elements from carbonatite ores. The surface of particles in the supernatant of rare earth elements’ ore was negatively charged, with the median zeta potential of the 0.025 mm fraction being at its minimum of −60.6 mV.

AbstractFerrocene‐modified natural compounds are of interest for the development of new pharmaceuticals due to improved bioavailability, increased bioactivity, and also as redox markers or vectors. Betulin is a natural plant‐derived product with a wide range of pharmacological properties. However, it is limited in its bioavailability and efficacy. In order to enhance its pharmacological profile, the ferrocene modification of betulin was used in this study. A hybrid of the betulin core (up to 30 % betulin in birch bark) with a ferrocene moiety combined through a piperazine linker (compound 12) was prepared in good yield from readily available ferrocene carboxylic acid and betulonic acid, a natural betulin derivative, via coupling reactions. Spectroscopic techniques, including 1H and 13C NMR, IR and UV‐vis spectroscopy, as well as circular dichroism (CD), were applied to characterize the physicochemical and chiroptical properties. The cytotoxicity of the synthesized hybrid 12 and its ferrocene precursor 13 on MCF‐7 human cancer cell lines were in vitro evaluated by the MTT assay. The IC50 cytotoxicity index of 12 was found to be 26 μM. The theoretically calculated energies of the HOMO‐LUMO orbitals and electronic characteristics of betulin 10, betulonic acid 11, hybrid 12 and ferrocenyl piperazine 13 were determined by the DFT method with hybrid functionals ωB97XD, LC‐ωPBE and B3LYP‐D3 and pure M06 L functionals, with a 6‐311+G(d), 6‐31G(d) or TZV basis set.

AbstractIn this work, a chemically stable NiMoO4/NRGO nanocomposite was prepared via a facile hydrothermal method. The flower‐like structure of NiMoO4 (NMO) nanoparticles is randomly distributed on the surface of nitrogen‐doped reduced graphene oxide (NRGO) sheets, as observed in FESEM images. Compared to related reports, the NMO/NRGO (II) nanocomposite exhibits an excellent high surface area of 368.9 m2 g−1 and a mesoporous nature, as shown in N₂ adsorption‐desorption isotherms. The specific capacitance of the NMO/NRGO (II) electrode is 721 F g−1 at 1 A g−1 using a 6 M KOH electrolyte, retaining 91.2 % of its initial value after 5000 cycles. Electrochemical impedance spectroscopy (EIS) reveals that the electrode has a lower charge‐transfer resistance, indicative of good electrochemical behavior. An asymmetric device consisting of NMO/NRGO (II) || activated carbon (AC) electrodes exhibits a high energy density of 49.1 Wh kg−1 at 524.4 W kg−1 within a voltage range of 1.4 V, retaining 89 % of its initial capacitance after 5000 cycles, demonstrating good cyclic durability. These results suggest that the NMO/NRGO (II) electrode is a promising active material for supercapacitor devices.

Published: September 2024

AbstractDue to its higher overall performance than ordinary concrete, polymer concrete (PC) beam has been widely used in the field of structural engineering. However, it is widely recognized that PC cannot simultaneously achieve the highest mechanical strength and optimal damping performance to reduce vibration during its long‐term service lifetime. To address this contradiction, the effect of various diluents contents on the overall performance of PC was investigated first in this investigation. Experimental findings revealed that the bending strength of PC exhibits an initial increase followed by a decrease with an increment of diluents, while its damping ratio displays an inverse trend. To obtain excellent overall performance (higher flexural strength and damping ratio) of PC, gradient PC has been manufactured by horizontal partition casting process (HPCP) and stereoscopic layered casting process (SLCP). Experimental results demonstrated that the gradient PC manufactured by HPCP exhibited better overall performance compared to SLCP. Furthermore, the graphite and carbon fiber were incorporated into the above gradient PC, and experimental results revealed that the incorporated graphite and carbon fiber can further increase the overall performance of the above gradient PC. Similarly, the incorporation of glass fiber cloth and carbon fiber cloth, along with surface treatment, significantly enhanced the overall performance of PC. The significance of this study lies in enhancing the comprehensive performance of PC beam structures, thus broadening its utilization scope within structural engineering.

AbstractGreen hydrogen development plays an essential role in creating a sustainable and environmentally conscious society while reducing reliance on traditional fossil fuels. Proton Exchange Membrane Water Electrolysers (PEMWEs), are sensitive to water quality, with various impurities impacting their efficiency, the quality of the hydrogen produced, and the device‘s lifespan. High‐purity water is required for PEM electrolyzers; Type II water, which is required for commercial electrolyzers, must have a resistivity greater than 1 MΩ cm, sodium, and chloride concentrations less than 5 μg/L, and total organic carbon (TOC) content less than 50 parts per billion. The majority of electrolyzers operate on freshwater, or total dissolved solids (TDS) <0.5 g/kg, whereas brackish, rainwater, wastewater, and seawater have TDSs of 1–35 g/kg, 0.01–0.15 g/kg, 0.5–2 g/kg, and 35–45 g/kg, respectively. This critical review offers, for the first time, a comprehensive overview of relevant impurities in operating electrolyzers and their impact. The findings of this study indicate that electrolysis‐based H2 processes are promising options that contribute to the H2 production capacity but require improvements to produce larger competitive volumes. In addition, the main challenges and opportunities for generating, storing, transporting, and distributing hydrogen, as well as large‐scale adoption are discussed.
Empowering Agency: Enhancing Health Literacy Among Migrant Women Through Health Parties: A Case Study

Published: September 2024

AbstractThis chapter explores how agency involvement through Health Parties can generate and promote learning agencies for migrant women to enforce health literacy. The Norwegian healthcare system struggles to provide sufficient responses to the needs of current and potential patients of the migrant population, particularly migrant women. A lack of cultural sensitivity and a more bottom-up approach is needed. Inspired by Tupperware Parties, this chapter explores the model of Health Parties, initiated by the female network of migrant women, called Kvinnenettverket Noor in Norwegian. A Health Party is based on a model where a host invites female friends, family, and acquaintances to a party to share information and learn about a relevant health issue by creating an appropriate space for discussion among experts and participants. This model can be employed when working to fulfil the United Nations Sustainable Development Goals concerning health and equity for migrant women. An explorative qualitative community-based participatory study design was employed. Data were collected by analysing participant observations and semi-structured face-to-face interviews in seven arranged Health Parties from September 2015 to March 2016. Health Parties generate learning agencies by providing space for active participation for migrant women. The healthcare system, which is based on Norwegian norms and culture, created cultural alienation and barriers that migrant women need space and knowledge to overcome. The results show the need for a public healthcare system and its professionals to be more sensitive and better adjusted to cultural diversity. They also provide insights into how migrant women gain agency about health issues by attending a Health Party. New ways of communication are required and found in the model of Health Parties for addressing health literacy among migrant women.
