Copper accelerates photochemically induced radical chemistry of iron-containing SOA
Authors: Kilchhofer Kevin , Ammann Markus , Torrent Laura , Cheung Ka Yuen , Alpert Peter Aaron
Published: October 2024

Abstract. Photochemical aging in secondary organic aerosol (SOA) particles alters their chemical composition and affects their adverse health effects. However, there is limited mechanistic insight on the role of transition metals in photochemical SOA aging and the evolution of the oxidative potential through their effect on radical chemistry. Here, we investigated the influence of copper (Cu) on the photochemical aging of iron (Fe) containing SOA in single particles using scanning transmission X-ray microscope measurements and chemical box modeling. The SOA proxy included citric acid (CA), iron(III) citrate (FeIII (Cit)) and copper(II) citrate (CuII (HCit)), which were exposed to UV light (λ = 365 nm) in a humidified environmental cell. We modeled known catalytic radical destruction mechanisms resulting from cross-redox reactions between copper and iron. Simulating anoxic FeIII (Cit)/CuII (HCit)/CA aging experiments showed a lower initial iron(III) reduction compared to FeIII (Cit)/CA particles, indicating a reduced iron(II) quantum yield than the photolysis of the FeIII (Cit) alone. We hypothesize that this effect may be due to copper replacing an iron center in a polynuclear complex. At higher relative humidity (RH) up to 60 %, a lower iron(II) quantum yield could not account for our observations of iron reoxidation in the dark. Instead, reoxidation appears to be highly sensitive to a potential copper(II)-induced reoxidation reaction. We provide a comprehensive discussion and evaluation of the poorly understood role of copper in modifying redox and radical chemistry, which is relevant for reactions involving transition metals mixed with SOA in the atmosphere.

Abstract. Stratosphere-troposphere Processes And their Role in Climate (SPARC) Quasi-Biennial Oscillation initiative (QBOi) project has conducted new experiments to explore the modulation of the QBO by El Niño-Southern Oscillation (ENSO). This paper provides an overview of the experiment design and investigates the modulation of the QBO by ENSO using nine climate models from the QBOi. A key finding is a consistent lengthening of the QBO period during La Niña compared to El Niño across all models, aligning with observational evidence. However, the magnitude of this lengthening shows large intermodel differences. By contrast, even the sign of the ENSO effect on QBO amplitude varies among models -models employing variable parameterized gravity wave sources generally exhibit greater sensitivity of the QBO amplitude to the presence of ENSO than those models using fixed sources. The models capture key observed ENSO-related characteristics, including a weaker Walker circulation and increased equatorial precipitation during El Niño compared to La Niña, as well as a characteristic response in zonal mean zonal wind and temperature. These modulations influence the propagation and filtering of gravity waves. Notably, models with variable parameterized gravity wave sources show stronger wave forcing during El Niño, potentially explaining the shorter QBO period modulation in these models. Further investigation into the complex interplay between ENSO, gravity waves, and the QBO can contribute to improved model formulations.
A/Void Pregnancy? Yagi Emi’s Kūshin techō and Fake Pregnancy as a Means of Exploring Women’s Struggles
Authors: Specchio Anna
Published: October 2024

Kūshin techō (Diary of a void), Yagi Emi’s brilliant debut in the Japanese literary scene, was published in 2020 and proceeded to win the 36 th Osamu Dazai Prize. With its provocative tones, the novel addresses maternal issues during a very crucial moment for literature. Indeed, contemporary women’s writing from all over the world is growing more and more engaged with issues such as illness, disease, healthcare, medical practice, and clinical institutions, as well as with the topic of “care,” usually depicted as a women’s responsibility. In this paper, I argue that, through the parody of the Maternal and Child Health Handbook, Yagi Emi advances a critique of the condition of Japanese women in contemporary Japan. More specifically, the use of the fake pregnancy and the diary as a narrative strategy serve as a means to explore contradictions and gender gaps women face during pregnancy, in the workplace and at home, such as sekuhara (sexual harassment) and matahara (maternal harassment), social pressure, prejudice and stigma, and economic inequality. At the same time, I argue that the absence of a male partner throughout the narrative reveals the prejudice and stigma surrounding unmarried pregnant women in Japan, and on the other hand, it makes it possible to read Kūshin techō as an example of Hélène Cixous’ écriture feminine.

Forecast calculations show that the possible use of surface runoff for agriculture and industrial production by 2040 will be no more than 24.4 km3/year, and taking into account non-productive losses it will be possible to use up to 21.5 km3/year of water resources [1]. On the territory of Kyzylorda province, the water factor acquires a leading role in the ecological sustainability of the natural environment. The main cause of environmental problems in the river basin is pollution and chronic water deficit. Therefore, providing the population and various sectors of the national economy with water in the required quantity and quality is the most important problem of our time. The level of anthropogenic pressures on water resources is determined by quantitative and qualitative indicators of water use, wastes of life activity entering the water source and their compatibility with the natural environment. Despite the reduction of return water discharges to water sources, water quality in all water bodies remains unsatisfactory [2]. At the present stage, both in Kazakhstan and abroad, to utilize the increasing volume of wastewater, the natural method of water treatment on irrigated fields has been increasingly used, with maximum use of nutrients contained in wastewater. In this case, irrigated fields can be considered as the final link of their natural disinfection treatment, which has socio-economic, environmental and technological aspects.

Published: October 2024

This research aims to provide researchers with a fresh perspective on the topic of employee turnover in the textile industry of Pakistan by illuminating the connections between work environment, organizational justice, job embeddedness, employee engagement, and turnover intention. By conducting a thorough literature review, researchers are able to identify individual studies that investigated the connection between work environment, organizational justice, job embeddedness, employee engagement, and turnover intention in Pakistan's textile sector. 384 workers in the textile and garment industry in Pakistan provided the data for this study. In order to examine the hypothesized relationships, we used partial least squares structural equation modeling (PLS-SEM). Employee engagement is shown to be most strongly influenced by factors like a positive work environment, organizational justice, and job embeddedness of belonging in one's employment. Employees' intentions to leave the company are impacted negatively by their level of work engagement. Furthermore, the connection between the work environment, organizational justice, job embeddedness, and turnover intentions is mediated by employee engagement. Work engagement is strengthened by all of these factors, and a company's ability to recruit and retain top employees is ensured. For the first time, turnover intention with the work environment, organizational justice and job embeddedness are being considered and studied together in the single research model. Such findings hold important implications for the managers of textile industry in Pakistan to mitigate the issue of employer turnover.

The most common type of liver cancer is hepatocellular carcinoma (HCC), accounting for 75–85% of cases. Despite its associated side effects, sorafenib remains the standard treatment for HCC. Given the critical need to improve therapeutic efficacy while minimizing adverse effects, alternative drugs must be thoroughly investigated. Numerous studies indicate that combining sorafenib with metformin results in a more favorable treatment profile. The aim of this study was to employ bioinformatics methodologies to elucidate the molecular pathways and genetic underpinnings of metformin's efficacy in HCC treatment. Genes associated with metformin and its action against HCC (Huh-7 and HepG2 cells) were acquired from the NCBI-GEO data collection by utilizing pre-determined keywords. Subsequently, pathways implicated in metformin-mediated HCC treatment were analyzed through the Kyoto Encyclopedia of Genes and Genomes (KEGG). Our analysis revealed the involvement of multiple pathways, with metabolic pathways implicated in 80% of the total cases. Neurodegenerative pathways were involved in only around 60% of the total cases. These findings align with the multifaceted mechanisms of metformin’s action, encompassing adenosine monophosphate-activated protein kinase activation, apoptosis induction, insulin regulation, anti-inflammatory responses, and modulation of cell proliferation. This comprehensive investigation sheds light on the intricate molecular landscape underpinning metformin's therapeutic efficacy in HCC, thereby informing potential avenues for optimizing treatment strategies.

Coronary heart disease (CHD) remains a leading cause of mortality in Indonesia, and coronary artery bypass graft (CABG) surgery is frequently employed to manage arterial blockages. Despite its efficacy, the recurrence of heart disease post-surgery is a significant concern, highlighting the need for a deeper understanding of its influencing factors. The aim of this study was to examine the factors associated with the incidence of heart disease recurrence after coronary bypass surgery. This study employed a prospective observational design, analyzing hospital claim data from Indonesia's Social Security Agency for Health, known as Badan Penyelenggara Jaminan Sosial (BPJS) Kesehatan, from 2017 to 2022. The analysis included 5,947 patients who survived CABG surgery. Multivariable logistic regression was utilized to assess the relationship between patient demographics, comorbidities, socioeconomic status, and compliance with follow-up visits, as well as their impact on the recurrence of cardiovascular disease. The study found that 24.1% of patients experienced hospitalization recurrence. Patients with irregular follow-ups were less likely to experience recurrence (adjusted odds ratio (AOR): 0.63; 95%CI: 0.51–0.78). Other significant risk factors for recurrence included being self-employed (AOR: 2.09; 95%CI: 1.72–2.55), having comorbid conditions such as disorders of fluid, electrolyte, and acid-base balance (AOR: 3.55; 95%CI: 2.97–4.24), and experiencing cerebral infarction or stroke (AOR: 10.85; 95%CI: 8.24–14.29). In contrast, older age (AOR: 0.89; 95%CI: 0.88–0.91) and the presence of non-insulin-dependent diabetes mellitus (AOR: 0.35; 95%CI: 0.29–0.42) were associated with a lower risk of recurrence. Sex did not significantly influence the risk of recurrence (AOR: 1.18; 95%CI: 0.86–1.62). In conclusion, the study indicates a considerable rate of cardiovascular disease recurrence post-CABG in Indonesia, highlighting several key risk factors. Tailored postoperative management and strict adherence to follow-up protocols are essential for mitigating recurrence. These findings offer crucial insights for improving post-CABG health management strategies in Indonesia.

Influenza surveillance is important for monitoring influenza virus circulation and disease burden to inform influenza prevention and control measures.  The aim of this study was to describe the epidemiology and to estimate the incidence of influenza in two communities in West Java, Indonesia, before and after the 2009 H1N1 pandemic. A population-based surveillance study in the community health care setting was conducted to estimate the annual incidence of influenza. A real-time reverse transcription polymerase chain reaction (RT-PCR) assay was used for influenza case ascertainment. A population census was implemented to calculate the population at risk and estimate community health care utilization rate. The mean annual incidence of influenza A and B, adjusted for healthcare utilization, was 1.6 (95%CI: 1.3–2.0) and 0.7 (95%CI: 0.5–1.0) per 1000 persons, respectively, with the most affected group being young and school-age children. The annual cumulative incidence of influenza A for children under five in 2009, 2010, and 2011 was 7.0 (95%CI: 4.4–11.2), 10.6 (95%CI: 7.3–15.4), and 6.3 (95%CI: 3.8–10.2). For influenza B was 4.3 (95%CI: 2.4–7.8), 2.0 (95%CI: 0.8–4.7), and 0.4 (95%CI: 0.1–2.8), respectively. This study highlights that the incidence of influenza among young and school-age children is consistently higher compared to adults and the elderly throughout these periods. These populations are potential targets for influenza vaccination in Indonesia.

Published: October 2024

The present research aims to determine the influence of coconut fibers from coconut palms on the physical and mechanical properties of compressed and cement-stabilized earth blocks. The study focused on the density, capillary absorption, compressive strength and flexural strength of the blocks. The first part of this study is devoted to the determination of the characteristics of the soil and those of coconut fibres. Five fiber contents (0, 0.1, 0.2, 0.3 and 0.4%) were used and the soil consists of 70% sand and 30% clay silt. Three cement contents were incorporated (2%; 4% and 8%). Two types of specimens are then manufactured by mixing the fibres with the earth-cement matrix: 14x9.5x29.5 cm3 blocks for compression and 4x4x16 cm3 briquettes for bending. The latter are stored away from the sun until maturity. From his studies, it appears that the density of the blocks decreases with increasing fiber content and the opposite is observed with capillary absorption. Overall, the compressive strength decreases with increasing fiber content and increases with cement content. However, the flexural strength increases with the fiber content but within a certain limit: beyond 0.3% fiber, the strength drops.

Comparison of the Effect of Structured Lifestyle Changes Versus Verbal Advice Only on Blood Pressure Control Among Hypertensive Adults in a Tertiary Hospital in North Central Nigeria
Authors: D.A Salihu , S Yohanna
Published: October 2024

Background: Results from several clinical trials show that comprehensive behavioral intervention programs improve lifestyle behaviors and lower blood pressure. The study compared the effect of structured lifestyle modification versus verbal advice only on blood pressure control among hypertensive adults presenting in the GOPD of JUTH.
Study Design/Setting: The study was a randomized study involving hypertensive adults aged 20 years and above presenting in GOPD of JUTH.
Methods: Participants were consecutively selected and randomized into two groups, a structured lifestyle modification group (Group A) and a verbal advice only group (Group B). Group A was offered a structured lifestyle modification counseling while routine advice only was offered to group B. Data was collected about patients’ socio-demographic, medical and lifestyle habits that included dietary and exercise history. Physical examination included blood pressure measurement. Participants were followed up monthly for twelve weeks during which blood pressure measurement was routinely carried out and changes in their lifestyle habits reported. The primary outcome was reduction in BP. The means at 95% confidence intervals of the blood pressure values of the two groups were determined using paired t-test analysis. Data was analyzed on an intention to treat basis. A p-value of <0.05 was considered significant in all analyses.
Results: The mean systolic blood pressure reduction in group A was 17 mmHg (8.7, 25.3; 95% CI) after 12 weeks versus 6.67 mmHg (0.47, 12.87, 95% CI) in group B. The mean diastolic pressure reduction after the same period was 8 mmHg (3.5, 12.5; 95% CI) in group A and 5.33 mmHg (1.5, 9.1; 95% CI) in group B. Paired t-test analyses revealed that these reductions were statistically significant in both groups.
Conclusion: Findings from the study show that individuals with hypertension can make and sustain, during a period of 12 weeks, multiple lifestyle modifications which can control or reduce blood pressure. There is therefore a need for improved lifestyle intervention programs, including those appropriate for delivery in the clinical setting, that enable individuals with or at risk for hypertension to adopt long-term healthier lifestyles

Capítulo 3. Sostenibilidad de los medios de comunicación del tercer sector en México. Una ruta para su fortalecimiento a través de la experiencia latinoamericana
Authors: Lemus Pool María Consuelo , Bárcenas Curtis César
Published: October 2024

El capítulo examina la sostenibilidad de los medios de comunicación del tercer sector en México, enfocándose en la comparación de marcos regulatorios y acciones de fortalecimiento con Argentina y Uruguay. El objetivo es identificar prácticas efectivas en otros contextos latinoamericanos que puedan adaptarse a la realidad mexicana. La metodología empleada es cualitativa y descriptiva, basada en el análisis comparativo de políticas públicas y entrevistas con expertos en cada país. Los resultados revelan que, a pesar del reconocimiento legal de los medios sociales, comunitarios e indígenas en México desde la promulgación de la Ley Federal de Telecomunicaciones y Radiodifusión (LFTyR) en 2014, persisten desafíos en términos de sostenibilidad, pluralismo y diversidad. Argentina y Uruguay han implementado medidas de fomento como fondos concursables y exenciones fiscales que han fortalecido la operación de medios comunitarios, aunque enfrentan problemas de acceso y periodicidad en los recursos. En contraste, en México, estas iniciativas son inexistentes, lo que subraya la necesidad de un entorno regulatorio más favorable y programas de apoyo específicos para estos medios. Las conclusiones sugieren que se requiere un mayor reconocimiento de las particularidades de los medios del tercer sector, incluyendo la creación de indicadores de evaluación claros y la simplificación de procesos administrativos. Además, se destaca la importancia de incorporar representantes del sector en los organismos reguladores para asegurar la adecuación de las políticas a las necesidades reales de estas comunidades. Estos pasos son fundamentales para avanzar hacia una comunicación más inclusiva y democrática, respetando la diversidad cultural y promoviendo la participación activa de la sociedad civil organizada.

Fungicides play a vital role in protecting crops from fungal damage.However, fungicide re-sistance is one of the most important issues in modern agriculture. Hence, it is very neces-sary to develop new fungicides constinuously.Triazole compounds have received consider-able interest in agricultural chemistry due to a novel action mode, extremely high activity against phytopathogenic fungi, low acute toxicity to mammals, and environmentally benign characteristics. The title compound 1-(3,3-dimethyl -2-oxobutyl)-N-phenyl-1H-1,2,4-triazole-3-carboxamide 5, synthesized using methyl 1H-1,2,4 -triazole-3-carboxylate 1 as the start material, was successfully obtained via multi-ple synthesis route and finally characterized by 1H NMR,13C NMR, HRMS and single-crystal X-ray diffraction. Compound 5 (C15H18N4O2, Mr = 287.1500) belongs to the orthorhombic system, space group Pn21a, with a = 14.49451(11)and#197;, b = 20.34686(18)and#197;, c = 10.17021(9)and#197;, V =2999.38(4) and#197;3, Z = 8, Dc= 1.268 g/cm3, T = 293.55(14) K, μ (CuKα) = 0.710 mm-1, F (000) =1216.0, the final R=0.0448, and wR = 0.1260 with Iandgt;=2σ (I). Fur-thermore, the results from biological assays indicated that the title compound exihibited a similar antifungal activity（EC 50 =8.98 mg. L-1）compared to triadimefon (EC50=5.6 mg.L-1)against G. cingulatal. And had different degrees of weak activity against other phy-topathogenic fungi, including A. solani, S. sclerotiorum, G. saubinetii and T. cucumeris. Po-tentially, the result lay the foundation for the development of novel fungicides

Published: October 2024

The prospective use of C24N24 fullerene in Li-, Na-, K-, and Mg-ion batteries (MIBs) was evaluated by density functional theory. The results showed that M-ion (M=Li, Na, K, and Mg) and M-atom were absorbed in the N4 cavity of C24N24 fullerene. The storage capacity of Mg-ion batteries (MgIBs) is 516 mAhg-1, which is larger than that of Li-, Na-, and K-ion batteries (LIBs, SIBs, and PIBs) with a value of 258 mAgh-1. Moreover, the cell voltages for LIBs, SIBs, PIBs, and MgIBs were calculated when C24N24 fullerene was used as the anode material. The results of the calculations are -1.75 V, -1.81 V, -2.82 V, and 2.74 V towards LIBs, SIBs, PIBs, and MgIBs, respectively. This research demonstrates that C24N24 fullerene may be a useful electrode material for MgIBs
Cost analysis of total knee arthroplasty surgeries in Turkey
Authors: SEVİNÇ H.F.
Published: October 2024

Background and study aims: While working with increasing costs, hospital enterprises try to develop strategies to provide high quality services. In this study, we intended to perform the cost analysis of total knee arthroplasty.

Materials and Methods: A total of 503 patients who were treated with total knee arthroplasty surgery due to gonarthrosis at Nev?ehir State Hospital Orthopedics and Traumatology clinic were included in the study. Procedures performed while the patient is in hospital were analyzed by dividing them into the costs of the implant applied to the patient, surgical procedure, medications used, blood and blood products transfusion, medical tests, anesthesia procedure, bed fee and other applied procedures.

Results: The mean total cost was 7560.2 Turkish Lira (TL). The mean cost of the implant applied to the patient was 4847.7 TL, that of surgical procedure was 1800 TL, medications used 371.1 TL, blood and blood products transfusion 38.7 TL, medical tests 38.3 TL, anesthesia procedures 142.7 TL, bed fee 195.2 TL and other applied procedures 122.9 TL.

Conclusion: In the cost analyses made in this study, it is observed that the share of implant, surgical procedure and anesthesia costs within the total cost is approximately 90%. It is not possible to cut back on the producedures in this 90% part and to modify them. To reduce the total cost, it seems most reasonable to focus on the costs of blood and blood products transfusion, medical tests, medications used and bed fees.

A recepção da vacina contra a Covid-19 foi controversa e rejeitada por parte significativa da sociedade no período pandêmico, o causador identificado inicialmente em Wuhan na China, foi o contexto geográfico que forneceu os aportes políticos e ideológicos para os ataques à vacina e à estratégia de contenção da pandemia. Posto isso, o presente artigo tem o objetivo de compilar dados e avaliar a possível influência dos discursos políticos no processo de receptividade vacinal contra a Covid-19. Caracterizado como um estudo de natureza exploratória, descritiva e explicativa quanto aos fins, e qualitativo quanto aos meios, em função de sua natureza, se valerá de avaliações comparativas entre discursos políticos do Grupo dos Vinte (G20) encontrados em revistas eletrônicas de alta popularidade e taxas de aceitabilidade a vacinação de cada população em questão. Em paralelo, fará uso de instrumentos teóricos filosóficos e sociológicos para avaliação dos dados seguindo a categorização proposta por Bardin (2016). O movimento que parece ter sustentado a rejeição, foi o conflito ideológico e geopolítico entre potências ocidentais e orientais, nunca superado desde as duas grandes guerras. A novidade foi o instrumental das redes e mídias socias na difusa comunicação em massa. Ainda assim, percebe-se que a cultura vacinal propiciou a busca pela imunização, no entanto, acendeu o alerta em relação aos grupos anticiência e a imagem do ‘líder’ a favor do ‘povo’.

Authors: Kozhuhova E. , Novikov V.
Published: October 2024

A study was made of the productivity of photosynthesis in peas of leafy and semi-leafless samples of the period shoots - budding under the conditions of the Krasnoyarsk forest-steppe. The following tasks were set: to analyze the elements that affect the intensity of photosynthesis during the period of germination - budding, and to evaluate the net productivity of photosynthesis in pea samples of different morphotypes. It was found that in the seedling phase, the indicators of the area of stipules and the collection of air-dry matter of semi-leafless samples can compete with leaf samples, even taking into account the summed area of their leaves and stipules. In the budding phase, the summed area of leaves and stipules of leaf samples exceeds those of semi-leafless samples. NPP and the maximum increase in dry matter for the accounting period shoots - budding was detected in a sample with a modified mustachioed type of leaf - Zh-55, with a minimum increase in the leaf surface.

Published: October 2024

The assessment of the zoned cultivars of double-row and six-row barley in terms of influence of productivity traits on final yield in a competitive variety trials for 2009-2022 (except 2011 and 2019) was carried out. Researches were conducted under the conditions of the open Krasnoyarsk forest-steppe. As objects of the research double-row barley varieties were used: Buyan, Kedr, Biom, Olenek, Acha, Bakhus, Krasnoyarsky 80, as well as six-row barley varieties: Agul 2 and Sobolek. The regression analysis showed that the yield substantially depended on a number of grains in an ear and a 1000-grain mass for double-row varieties as well as for six-row ones of the siberian ecotype. The difference of varieties of the krasnoyarsk early days selection – Krasnoyarsky 80 and Bakhus is revealed. Little influence of all basic productivity traits on yield is typical for them.

Published: October 2024

This study aimed to evaluate the potential anti-Alzheimer’s activity of Amaranthus viridis Linn leaves extract in rats. The leaves were extracted using methanol, and the phytochemical analysis revealed the presence of flavonoids, tannins, and alkaloids. Adult female Wistar rats were divided into five groups: control, Alzheimer’s-induced, low-dose Amaranthus viridis extract-treated (200 mg/kg), high-dose Amaranthus viridis extract-treated (400 mg/kg), standard drug-treated (donepezil). Alzheimer’s disease was induced using scopolamine. Cognitive functions were assessed using the Morris water maze and Elevated Plus Maze tests. Biochemical parameter, includes acetylcholinesterase activity was measured in brain tissues. Both low-dose and high-dose Amaranthus viridis extract-treated groups showed significant improvement in memory retention and spatial learning compared to the Alzheimer’s-induced group, with the high-dose group showing greater efficacy. Biochemical analysis revealed a substantial decrease in acetylcholinesterase activity in both extract-treated groups, aligning closely with the standard drug-treated group. The findings suggest that Amaranthus viridis Linn leaves extract exhibits notable anti-Alzheimer’s activity, potentially through mechanism involving inhibition of acetylcholinesterase. This study supports the traditional use of Amaranthus viridis in cognitive disorders and highlights its promise as a natural therapeutic agent for Alzheimer’s disease.
