Novel Approach to Investigate the Effect of High-Dose Methylprednisolone on Erythrocyte Morphology: White Light Diffraction Microscopy
Authors: Deniz Cigdem , Kocahan Ozlem , Altunan Bengu , Unal Aysun
Published: October 2023

The present study focuses on quantitative phase imaging of erythrocytes with the aim to evaluate the effects of high-dose methylprednisolone (HDMP) on erythrocytes in vivo under physiological conditions in human blood samples. Samples from ten patients, prescribed to be treated with 1000 mg/day intravenous methylprednisolone for 5 days, were analyzed by white light diffraction phase microscopy (WDPM) for quantitative imaging. WDPM, an optical measurement technique, enables single shot measurement and low speckle noise using white light. Quantitative phase imaging performed with this experimental setup allowed the determination of erythrocyte morphology with 9 different parameters. In vivo quantitative analysis of erythrocytes by WDPM, which is a simple and reliable method, shows that HDMP treatment has no significant effect on erythrocyte morphology. With the developing technology, interdisciplinary studies on individuals under treatment should play an important role in elucidating the interaction between steroids and erythrocytes.

Published: October 2023

Duchenne muscular dystrophy (DMD) is a genetic neuromuscular disorder with X-linked inheritance, characterised by progressive motor deficit, causing loss of the ability to walk and multisystemic complications. Currently, there is no known aetiologic treatment for DMD which seeks to remove or correct its cause. Progressive respiratory muscle damage associates thoracic deformities, and ineffective cough, which leads to significant complications such as hypoventilation, nocturnal desaturation and chronic respiratory failure. Respiratory impairment represents the major cause of mortality in patients with muscular dystrophy. This highlights the importance of early and correct management of this illness. We present the case of a 17-year-old patient, genetically diagnosed with DMD at the age of 5 years that became non-ambulant at the age of 12. He had complications such as iatrogenic Cushing syndrome, anxiety, depressive disorder, mild cardiac dysfunction, severe restrictive respiratory dysfunction, nocturnal hypercapnia and sleep apnoea syndrome treated with BiLevel Positive Airway Pressure Spontaneous/Timed Therapy (BiPAP-ST). In evolution, it was decided to perform a tracheostomy and quasi-permanent ventilation. The clinical and paraclinical presentation of this patient is typical of that of an advanced stage of DMD, with progressive aggravation in the past years, despite the correct multidisciplinary management, following the international care standard of this disease. The particularity of the case is based on the complexity of all the comorbidities associated with the disease and the impact they have on the mental health of the patient, leading to the degradation of his general state. Having limited respiratory function, the patient died secondary to a tracheostomy tube complication. These complications represent a major cause of mortality in patients with neuromuscular disorders. An early and correct management of the respiratory tract pathology of these patients is essential for improving their quality of life and increasing their life span.

Abstract

Strawberry (Fragaria x ananassa Duchesne) is one of the high-demand commodities in Bali. This study aims to determine how the strawberry supply chain works from farmers to supermarkets (Tiara Dewata Distribution Center Denpasar). This research consists of two stages, the observation of the working structure of the supply chain using descriptive-qualitative analysis and the added value of each supply point using the Hayami method. This study used total sampling (to determine the sample at the collector and supermarket level) and purposive sampling (to determine the farmer level). The results showed that the flow pattern of the strawberry supply chain consisted of Pattern I (farmers selling to collectors and collectors selling to supermarkets) and Pattern II (farmers selling directly to supermarkets). The biggest added value by the supermarket (Rp. 39,184 per kilogram). Farmers who sell to collectors provide the added value of Rp. 17,989 per kilogram. Farmers who sell to the supermarket provide the added value of Rp. 20,155 per kilogram. The smallest added value by collectors is Rp. 4,745 per kilogram.

Abstract

Farmers in Bali have not been able to produce good seeds due to failures at the storage stage and are still dependent on potato seeds from the G2-G4 group imported from outside. The aim of this study was to determine the dynamics of air temperature and humidity (RH) during the storage of potato seeds and the physical changes of potato seed tubers after storage. Parameters measured included temperature and humidity during storage of potatoes, analysis of mass and energy balances, calculation of respiration heat, heat for increasing the temperature of potatoes, heat for water evaporation, and heat lost to the environment with a simple mathematical model approach. The results showed that temperature tends to form a quadratic polynomial pattern, while RH tends to form a linear pattern. The temperature of the potato storage room was in the range of 29.50 ºC - 29.09 ºC and the RH was in the range of 73.00% - 81.80%. Respiration heat value varies between 470.26 - 491.30 Watts. The heat generated from the respiration process is 72 -143 watts, the heat to raise the temperature of the potato tubers around the potatoes is 2.02 Watts; 1.81 Watts; 3.80 Watts; 2.60 Watts; 10.70 Watts; and 15.20 Watts. The heat lost to the environment forms a linear pattern. Para-Para is capable of creating conditions for the storage and supply of oxygen that, for physical change, are almost non-existent.

Objective: This study aimed to investigate the prevalence of depression and anxiety, examine how different shift work schedules (day, evening, night, and rotation) relate to mood and anxiety disorders in female nurses in Saudi Arabia, and identify the least impactful shift in mental health.
Methods: This was a cross-sectional, community-based study that used validated questionnaires to assess depression Patient Health Questionnaire (PHQ-9) and anxiety Generalized Anxiety Disorder (GAD-7) in female nurses in Saudi Arabia.
Results: The study included 418 female nurses in Jeddah, Saudi Arabia. The majority of them were aged 25-34 years and had Indian nationality. Most nurses were married, held a diploma degree, and had 10-20 years of experience. Around 33% experienced minimal or no depression, and 49.3% had minimal or no anxiety, while the rest experienced mood disorders during their working shifts. Day shifts were the least associated with depression and anxiety. While rotating shifts were significantly associated with no depression. Previous mental disorders (OR = 2.6) and the working department (Pediatric Ward) (OR = 0.12) were two significantly associated factors with poor quality of life in nurses.
Conclusion: Depression and anxiety were common during work shifts. Daytime shifts had lower levels of mood disorders, and rotating shifts showed no significant depression. Tailored interventions are crucial for fostering resilience and enhancing patient care.

Recently, hydroxamic acid has attracted considerable interest because of its ability to inhibit a variety of metal-containing enzymes such as metalloproteases, lipoxygenases, histone deacetylases, and cancer cells. For example, hydroxamic acid derivatives (vorinostat, belinostat, givinostat, panobinostat) have been approved by the US FDA for the treatment of various cancers. Based on the N-hydroxycinnamamide and N-hydroxybenzamide framework, the study described and synthesized N-hydroxycinnamamide and N-hydroxybenzamide derivatives bearing amide bonds as histone deacetylases enzyme inhibitors. The structures of the compounds were determined through modern NMR spectroscopy. The compounds were then molecularly docked to the active site of the HDAC6 enzyme, the results showed that the compounds strongly bound to the zinc ion and key amino acids. These results suggest that the synthesized N-hydroxycinnamamide and N-hydroxybenzamide derivatives are potential molecular targeted therapy for HDAC positive cancer in the future.

The wild honeybees, Apis dorsata Fabricius, 1793 and Apis florea Fabricius, 1787 constitute a large proportion of pollinators’ abundance on most crop species in Punjab, Pakistan. In the present study, we studied the foraging behavior of both the honeybee species and their comparative role in the reproductive performance of the strawberry at the research farm of The Islamia University of Bahawalpur. Both the species comprised 53% of the total pollinators’ abundance. Apis florea had high visitation frequency (0.449±0.03 individuals per 120 seconds) than A. dorsata (0.211±0.02). The activity of A. florea was the maximum at 12:00 pm while A. dorsata remained active in low abundance throughout the day. Apis florea exhibited a higher stay time but a lower visitation rate than A. dorsata. Apis dorsata proved to be an effective pollinator of the strawberry rather than A. florea in terms of fruit length, weight and diameter. There is a need to conserve wild honeybees under the current scenario of anthropogenic land use changes and intensification in agriculture.

Floating hip describes a rare combination of fractures/dislocation and is usually seen in multiple injured patients, more often in young males involved in high-energy automotive/motorcycle trauma. These fractures are often associated to chest trauma, other skeletal fractures or polytrauma. A “floating hip” injury is rare but a surgical challenging. Each case needs to be planned and addressed. We present a case of floating hip injury in a male patient, treated successfully with ORIF, followed by an uneventful postoperative period.

Evaluating the Implementation of Public Participation in Service Delivery Planning in the Democratic Age: A Case of South African Municipalities
Authors: Kgobe France , Bayat Mohamed Saheed , Karriem Abdulrazak
Published: October 2023

The main objective of this article is to evaluate the implementation of public participation in service delivery planning in the democratic age. Over the past few years, there has been a shift in the responsibility of service delivery planning from a centralised (national) level of government to a more decentralised (municipal) level. Contemporary perspectives on planning suggest that the responsibility is no longer regarded as a hierarchical process, but rather as a collaborative process that involves the active participation of citizens as key stakeholders. The notion of public participation is regarded as a crucial factor in the democratisation of service delivery. This is a desktop study, also known as a conceptual study, that is based on collaborative planning theory and democratic decision-making theory to develop ideas and arguments. The article highlights the importance of public participation in service planning, emphasising its significance despite the intricate structures, obstacles, and substantial administrative challenges involved. The assessment is conducted to determine the viability of implementing practical strategies that can effectively support a sustainable service delivery process. The findings of the article indicate that the involvement of the public in integrated development planning (IDP) processes is of utmost importance in ensuring the long-term viability of service delivery. This study posits that it is imperative to assess the continued applicability of the integrated development planning tool in effectively addressing developmental obstacles in rural regions of South Africa. In addition, it is recommended that future studies prioritise the assessment of whether the practice of creating the service delivery budget implementation plan separately from the (IDP) process is not conducive to the emergence of service delivery protests. This would involve investigating the potential misalignment between these two factors across multiple municipalities.
Challenges of Disposal and Access to Electronic Records in the Midlands Province of Zimbabwe
Authors: Mutsagondo Samson , Ngulube Patrick
Published: October 2023

Disposal of electronic records is a challenge in many developing countries due to a number of factors such as deficiencies in skills, infrastructure, and legal and policy frameworks. Irresponsible, premature and uninformed destruction, preservation and transfer of electronic records directly affect access to the same now and in the future. Using the theoretical framework of the intergenerational equity theory, this study examines electronic records disposal practices and how they impact upon access to electronic documentary heritage now and in the future. This qualitative study was informed by the constructivist research paradigm and used the case study of government ministries in the Midlands province of Zimbabwe. Fifty-five out of 88 purposively selected public officers participated as interviewees. Data were also collected through personal observation where researchers observed electronic records disposal and access practices in ministries where access was granted. It was established that there were a number of challenges with regard to disposal of electronic records at a time when both the National Archives of Zimbabwe and the government ministries were incapacitated to properly preserve electronic records. Issues of infrastructure, skills and electronic records policies should be attended to so that the present and future generations may equally benefit from the nation’s electronic documentary heritage.
Invigorating Records Management Success through Archival Services in the Limpopo Provincial Government, South Africa
Authors: Marutha Ngoako Solomon , Malatji Ouma
Published: October 2023

The study that informed this paper investigated the possibilities of invigorating records management success through archival services in the Limpopo provincial government in South Africa. A multi-method research approach was used, with a questionnaire and interviews to collect data. It was discovered that provincial archive institutions in the Limpopo Province were under-resourced and, therefore, unable to render supportive services to the departments to enhance their records management. The provincial archives could not render services like training and support visits owing to a shortage of staff and lack of transport, among other reasons. The study provides a framework for invigorating records management success through archival services in the Limpopo provincial government, South Africa. This may help the provincial government of Limpopo to avoid audit disclaimers and litigation costs, to list only a few. The findings and recommendations of the study may serve as a resource and benchmark for organisational policymakers and strategists in improving records management services. Implementation of the proposed framework and recommendations may assist organisations in coming up with the best practices for the effective use of resources and support for smart records management strategies. Implementation of the recommendations of the study may also result in the best practices to properly manage records of enduring value, thereby preserving the memory and heritage of the state for citizens’ access. It will also strengthen proper administration and accountability for public services in the departments.
Unravelling the US-ROK Alliance: Decoding North Korea’s Strategy within the Six-Party Talks
Authors: Zhou Ian Fleming , Van Wyk Jo-Ansie
Published: October 2023

Alliance formation is a calculated decision by parties to determine and affect the outcome of negotiations. Its success depends on several factors, most notably alliance members’ cohesion and convergence of common interests, objectives, and tactics. The focus here is on the United States and South Korea’s alliance during the Six-Party Talks on North Korea’s nuclear programme. Despite early progress in the alliance’s favour, the internal cohesion of the US-South Korea alliance was disrupted due to divergent interests, approaches, and positions regarding North Korea. This research provides a comprehensive analysis of the US-ROK alliance’s impact on the Six-Party Talks. While previous studies have explored the negotiations, little attention has been given to the alliance’s role and how it evolved over time, especially in the context of North Korea’s manipulation and its consequences on negotiation outcomes. We assess the success of the alliance and its impact on the negotiation process, considering factors such as cohesion, common interests, objectives, and tactics. Our study adopts a qualitative research approach, utilising an extensive review of relevant literature, official documents, historical records, and primary sources from the Six-Party Talks. The findings underscore the importance of robust and well-coordinated alliances in addressing critical global security challenges. To achieve lasting success in future negotiations, it is imperative for allied parties to forge a shared understanding and strategic convergence in dealing with adversaries like North Korea. Moreover, this research calls for a re-evaluation of alliance dynamics and tactics to strengthen the collective resolve in pursuing international peace and security.
Queer Belonging in Durban, South Africa: Thoughts from the Zanele Muholi Homecoming Exhibition
Authors: Caili Forrest
Published: October 2023

In this article, I seek to queer belonging in a post-apartheid city space. I will do this by taking a queer orientation towards a particular public space—the Durban/eThekwini City Hall in South Africa, and a particular set of experiences I had there during the Zanele Muholi Homecoming exhibition in 2017–18. I will also seek to use these to unsettle the concept of belonging. This queering happens at two levels. First, how the relatively mainstream or institutional space of City Hall space was queered through the exhibition of a black queer artist at the Durban Art Gallery. Given that the City Hall was built to symbolise Britishness in the colonies, this occurrence, although momentary, is illuminating. Second, during my experiences at the exhibition there were several moments which stuck with me. I take one of these which took place with my mother and reflect on it to complicate our understandings of belonging. Ultimately, belonging operates in complex ways within post-apartheid cities demonstrated by one particular place and experience in Durban. For LGBTIQ+ people, belonging is many things. In this article, I demonstrate the possibilities of public art to claim belonging in a city not designed for queer black life, and some of the slippages and productivity of “not belonging” using the notion of reciprocity.
The Department of Transportation’s Failures in Regulating Emotional Support Animals
Authors: Doughty Jillian
Published: October 2023

In the past decade, the number of emotional support animals being used to treat a wide array of mental and emotional disorders has multiplied exponentially. This increase has been met with mixed reactions in the context of air travel. While some passengers are thrilled to sit next to a dog on their flight, others are frustrated due to the belief passengers with emotional support animals are exploiting a loophole to travel with their pet for free. Regardless of the differing perceptions, emotional support animals are a valid, affordable way to treat mental health illnesses without incurring negative side effects associated with medication.

The Department of Transportation (DOT) recently amended the regulations on emotional support animals to reflect grievances related to potential abuses of the system. These amendments unfairly discriminate against individuals with mental health illnesses while doing little to prevent exploitation and misrepresentation of service and emotional support animals. DOT should revert to the previous system of recognizing emotional support animals in a category distinct from service animals. Furthermore, implementing stricter regulations for the registration of emotional support animals, reducing pet fees, and keeping records of such in a robust database would allow those with mental disorders to rightfully obtain emotional support animals while curbing abuse of the system.

Published: October 2023

A dinâmica de transformação do planeta, através de processos naturais, associada à atuação antrópica, intensificada desde a primeira revolução industrial e pautada em um consumismo exacerbado dos recursos naturais, vem causando substanciais alterações negativas nos ecossistemas. Buscando garantir a preservação do meio ambiente, o constituinte de 1988 previu, em seu art. 225, VI, §1º, a promoção da educação ambiental, em todos os níveis de ensino, como mecanismo para assegurar o direito ao meio ambiente ecologicamente equilibrado, corolário da terceira dimensão dos direitos fundamentais. Neste contexto, o presente estudo busca analisar os aspectos teóricos e práticos da fundamentalidade do direito à educação ambiental no Brasil e a forma com a qual sua efetivação nas escolas pode contribuir para a redução de desastres ecológicos, notadamente no que tange às regiões vulneráveis. Os resultados demonstraram que a educação ambiental no espaço escolar se mostra imprescindível para a conservação e preservação do meio ambiente, contribuindo para a democratização do conhecimento acerca das problemáticas ecológicas oriundas das mudanças climáticas e capacitando a população civil a dirimir os impactos negativos da nociva atividade humana responsável pela degradação ambiental.

Through-space interaction (TSI), including through-space conjugation (TSC) and through-space charge transfer (TSCT), has emerged as a promising strategy for designing functional materials and constructing superior optoelectronic devices. Because of the multichannel charge transport and structural flexibility, TSI-based devices often exhibit high-performance optoelectronic properties, such as excellent photoluminescence, high charge carrier mobility, and outstanding device efficiency. In this review, the principles and characteristics of TSI are briefly introduced. Then we mainly focused on the recent progress of optoelectronic device applications based on materials with TSC and TSCT. Various advanced optoelectronic devices, including organic fluorescence film sensors, organic light-emitting diodes, single-molecule junctions, and photoswitches are discussed in detail and possible breakthroughs are proposed for future molecular design and efficiency enhancement.

An Aluminium composite metal, Al-Cu-CP was fabricated from recycled raw materials. The composite was fabricated by means of stir casting method due to its simplicity and economic worth. The composite and the unreinforced Al were both analysed for chemical and mechanical properties. The Al-Cu-CP metal composite produced has shown appreciable level of wear resistance and corrosion resistance in artificial seawater (3.5 g/L NaCl) and allowed to stand for 96 h at room temperature. Different loads were considered for the wear resistance tests, 5 N, 10 N, 15 N and 20 N while 150 rpm, 250 rpm, 350 rpm and 450 rpm were the speeds selected for the adhesive wear resistance test. Improved properties were observed after heat treatment of the Al-Cu-CP metal composite. The heat treated composite was more resistant to corrosion than the untreated composite and it has been confirmed that the corrosion resistance of the materials under study has direct relationship with the immersion period. When the maximum load was applied to the three (3) sets of the samples (unreinforced, treated and treated composites), severe degrees of wear manifested on their various surfaces. Optical images from morphological analysis revealed that wear severity was highest on the surface of the unreinforced matrix, followed by the untreated metal composite and the heat-treated composite was found to be the least affected. Due to these enhanced properties of the Al-Cu-CP metal composite, it could be recommended where high strength with light density product is required such as automobile brake shoes and brake disc as a result of its upgraded mechanical properties.
The utility of supercritical fluid chromatography for the separation and potential purification of organic light-emitting diode (OLED) materials

Screen technology for “smart” devices continues to advance as researches seek to enhance display performance by reducing energy consumption and improving color characteristics. To that end, researchers are turning to organic light-emitting diodes (OLEDs) as the display materials due to higher energy saving and richer color compared to liquid crystal displays (LCDs). However, one major setback of the OLED technology is that the devices are very sensitive to the impurities present in the OLED materials, impacting device lifetime, stability, and overall performance. The isolation of large quantities of the main OLED components from the synthetic impurities is challenging using the traditional purification process (i.e., train sublimation), which has poor reproducibility, and high capital and operating cost. Supercritical fluid chromatography (SFC) could lend itself as an alternative technique for the profiling of impurities and their purification. In this study, we investigated the use of SFC to analyze a mixture of amorphous monomeric molecular glasses with charge-transporting property typical of OLED materials. The separation behavior of four different chromatographic columns containing the stationary phases 1-aminoanthracene (1-AA), naphthyl, 2-ethylpyridine, and C-18 were examined to perform the SFC separations. The effect of using three different co-solvents (i.e., isopropyl alcohol, acetonitrile, and tetrahydrofuran) to the CO2 mobile phase on the separation selectivity and resolution was also investigated. For the probe mixture used, the naphthyl column in combination with the addition of acetonitrile as co-solvent provided the best separation in terms of resolution. The SFC method was farther optimized for co-solvent composition, temperature, pressure, and flow rate. The SFC analysis showed high resolution and short analysis time compared to HPLC, and also provided for the separation of small components that have been attributed to impurities in the sample.

The effects of temperature and chemical environment on a pentanuclear cyanide-bridged, trigonal bipyramidal molecular magnet has been investigated. Using element and oxidation state specific near-ambient pressure XPS (NAP-XPS) to probe charge transfer and second order, non- linear vibrational spectroscopy, which is sensitive to symmetry changes based on charge (de)localization coupled with DFT a detailed picture of environmental effects on charge-transfer induced spin transitions is presented. The molecular cluster, Co3Fe2(tmphen)6(μ-CN)6(t-CN)6, abbrev. Co3Fe2, shows changes in electronic behavior depending on chemical environment. NAP-XPS shows that temperature changes induce a metal-to-metal charge transfer (MMCT) in Co3Fe2 between a Co and Fe center, while cycling between ultrahigh vacuum and 2 mbar water at constant temperature, causes oxidation state changes not fully captured by the MMCT picture. Sum frequency generation vibrational spectroscopy (SFG-VS) probes the role of the cyanide ligand, which controls the electron (de)localization via the superexchange coupling. Spectral shifts and intensity changes indicate a change from a charge delocalized, Robin-Day Class II/III high spin state to a charge localized, Class I low spin state consistent with DFT. In the presence of a H-bonding solvent the complex adopts a localized electronic structure, while removal of the solvent delocalizes the charges and drives a MMCT. This change in Robin-Day classification of the complex as a function of chemical environment results in reversible switching of the dipole moment, analogous to molecular multiferroics. These results illustrate the important role of chemical environment and solvation on underlying charge and spin transitions in this and related complexes.

The rapid photochemical conversion of materials from liquid to solid (i.e., curing) has enabled the fabrication of modern plastics used in microelectronics, dentistry, and medicine. However, industrialized photocurables remain restricted to unimolecular bond homolysis reactions (Type I photoinitiations) that are driven by high-energy UV light. This narrow mechanistic scope both challenges the production of high-resolution objects and restricts the materials that can be produced using emergent manufacturing technologies (e.g., 3D printing). Herein, we develop a photosystem based on triplet-triplet annihilation upconversion (TTA-UC) that efficiently drives a Type I photocuring process using green light at low power density (<10 mW/cm2) and in the presence of ambient oxygen. This system also exhibits a superlinear dependence of its cure depth on light exposure intensity, which enhances spatial resolution. This enables for the first-time integration of TTA-UC in an inexpensive, rapid, and high-resolution manufacturing process, digital light processing (DLP) 3D printing. Moreover, relative to traditional Type I and Type II (photoredox) strategies, the present TTA-UC photoinitiation method results in improved cure depth confinement and resin shelf-stability. This report provides a user-friendly avenue to utilize TTA-UC in ambient photochemical processes and paves the way towards fabrication of next generation plastics with improved geometric precision and functionality.
