Embracing policy innovations from abroad: the role of learning in Chile’s anti-cartel reforms
Authors: Aydin Umut
Published: March 2023

Why and how do policymakers initially sceptical of policy innovations from abroad eventually transfer them to their own countries? Focusing on Chile’s reforms to combat business cartels in 2009 and 2016, this article answers that question. Policy diffusion and transfer literatures maintain that coercion, competition, learning or emulation could account for foreign inspirations in policymaking. However, these literatures overplay the role of coercion and emulation in policy transfer to countries in the global south, and have difficulty distinguishing between different mechanisms in empirical studies. To address these limitations, I suggest analysing three intermediate causal steps in policy transfer: first, policymakers’ motivations in initiating policy reforms, second, their reflections on how the foreign-inspired model responds to the policy problem at hand, and third, their reflections on the fit between the foreign model and domestic conditions. Through process-tracing of two anti-cartel reforms in Chile, I find that policymakers introduced foreign-inspired policy measures to combat business cartels through a process of learning from other countries and international organisations, rather than coercion or emulation. Learning was evident in three ways. First, in the initiation of the reform, as policymakers responded to a clearly identified policy problem; second, in policymakers’ careful reflection on how the foreign-inspired model responded to these problems; and third, in the adjustments made to fit the foreign model to domestic conditions. The analysis demonstrates the utility of analysing intermediate causal steps in policy transfer, and of paying more attention to local actors and political processes.
The effect of a novel AQP4 facilitator, TGN-073, on glymphatic transport captured by diffusion MRI and DCE-MRI
Authors: Alghanimy Alaa , Martin Conor , Gallagher Lindsay , Holmes William M.
Published: March 2023

The glymphatic system is a low resistance pathway, by which cerebrospinal fluid enters the brain parenchyma along perivascular spaces via AQP4 channels. It is hypothesised that the resulting convective flow of the interstitial fluid provides an efficient mechanism for the removal of waste toxins from the brain. Therefore, enhancing AQP4 function might protect against neurodegenerative diseases such as Alzheimer’s disease (AD), in which the accumulation of harmful proteins and solutes is a hallmark feature. Here, we test the effect of a putative AQP4 facilitator, TGN-073, on glymphatic transport in a normal rat brain by employing different MRI techniques. Surgical procedures were undertaken to catheterise the cisterna magna, thereby enabling infusion of the MRI tracer. Followed by the intraperitoneal injection of either TGN-073, or the vehicle. Using a paramagnetic contrast agent (Gd-DTPA) as the MRI tracer, dynamic 3D T1 weighted imaging of the glymphatic system was undertaken over two hours. Further, the apparent diffusion coefficient was measured in different brain regions using diffusion-weighted imaging (DWI). While physiological parameters and arterial blood gas analysis were monitored continuously. We found that rats treated with TGN-073 showed the distribution of Gd-DTPA was more extensive and parenchymal uptake was higher compared with the vehicle group. Water diffusivity was increased in the brain of TGN-073 treated group, which indicates greater water flux. Also, MRI showed the glymphatic transport and distribution in the brain is naturally heterogeneous, which is consistent with previous studies. Our results indicate that compounds such as TGN-073 can improve glymphatic function in the brain. Since glymphatic impairment due to AQP4 dysfunction is potentially associated with several neurological disorders such as AD, dementia and traumatic brain injury, enhancing AQP4 functionality might be a promising therapeutic target.
La violencia interpersonal a finales de la Edad Media. El asesinato de Nicolás abad de Arrieta (Lekeitio, Vizcaya, 1493)
Authors: Bazán Díaz Iñaki
Published: March 2023

En este artículo se realiza, en primer lugar, una breve reflexión sobre los argumentos de la preponderancia de la violencia en la Edad Media y sobre cómo abordar su estudio a partir de la Historia cultural y la microhistoria. Esta reflexión se centra en la violencia como característica estructural del sistema feudal; como característica de una cultura basada en el honor y en la venganza como mecanismo de resolución de conflictos; y como característica inherente a una sociedad emocional y carente de autocontrol. En segundo lugar, se analiza el caso del asesinato del clérigo Nicolás de Arrieta, acaecido en 1493 en la villa de Lekeitio (Señorío de Vizcaya), como ejemplo de violencia interpersonal y que permite adentrarse en el contexto social y cultural particular del conflicto y entender cómo se gestaba un crimen y se rompía la paz social. El estudio se estructura en los siguientes apartados: a) ¿cómo se produjo el asesinato?; b) ¿cómo llevó adelante la acusación y el proceso penal María Pérez de Arrieta, hermana del clérigo; c) las actuaciones judiciales y los conflictos jurisdiccionales; d) las condenas a los acusados; y e) ¿cuál fue la motivación del asesinato? El asesinato del clérigo Nicolás de Arrieta permite reconstruir y comprender, entre otras cuestiones, la capacidad de acción o agencia en el plano judicial de las mujeres; el funcionamiento de la justicia penal como mecanismo de control social disciplinario; la separación jurisdiccional entre villas y Tierra Llana en el Señorío de Vizcaya; el conflicto de la iglesia parroquial de Lekeitio con sus iglesias sufragáneas y su resolución a través de mecanismos arbitrales o, como es el caso, a través del ejercicio de la violencia.

As heterogeneidades hidroestratigráficas podem limitar o sucesso dos projetos de remediação. O presente estudo avaliou, em escala de detalhe, o alcance do remediador persulfato de sódio quando injetado por meio de poços com seções filtrantes de 1,0 metro interceptando duas unidades hidroestratigráficas de diferentes condutividades hidráulicas, em um aquífero com presença de contaminantes organoclorados em área de depósitos quaternários. A seção filtrante dos poços de injeção interceptava as camadas de: areia fina a média, pouco siltosa; e uma camada de areia grossa de granulometria variada com presença de pedregulhos. O monitoramento do fluxo de persulfato nas diferentes unidades hidroestratigráficas foi feito por meio da avaliação da água subterrânea nos poços. As amostras de água foram coletadas com amostrador por captura tipo bailer de inox. Foram realizadas medições de condutividade elétrica e pH com o auxilio de condutivímetro e pHmetro de bancada; concentração de persulfato com Klozur® Field Test Kits; e concentração de contaminantes dissolvidos na água por meio de análises químicas em laboratório acreditado. Os resultados destas medições mostraram que o fluxo de persulfato ocorreu quase totalmente na base da camada de areia grossa de granulometria variada com presença de pedregulhos, indicando que heterogeneidades hidrogeológicas formam caminhos preferenciais. Tal fato deve ser considerado em remediações com injeção de produtos remediadores, com vista à economia de recursos e melhor eficiência do sistema.

Published: March 2023

Hepatocellular adenoma is a benign liver tumor often diagnosed incidentally in women of reproductive age who are taking oral contraceptives. In this study, we present a unique case of an 18-year-old man with known familial adenomatous polyposis who presented with sepsis in the setting of a recent total proctocolectomy and was incidentally found to have multiple large hepatic lesions. A biopsy of a liver lesion confirmed the diagnosis of a beta-catenin-activated hepatic adenoma. To the best of our knowledge, this is the first known case of beta-catenin-activated hepatic adenoma in a patient with a known familial adenomatous polyposis mutation. Beta-catenin is one of the many subtypes of hepatocellular adenomas, which carries a high risk of malignant transformation.
Irrefutable Proof of The Non-Existence of a ‎Gravitational ‎Singularity at The Centre of a ‎Black Hole
Authors: Šorli Amrit
Published: March 2023

Astronomical observations confirm that gravitational force decreases with the square of the distance. If the gravitational force in the centre of Sagittarius A* were close to infinity and would decrease with the square of the distance, our Milky Way could not exist as we observe it. This fact is irrefutable proof that there is no gravitational singularity in the centre of Sagittarius A* and in general, there is no gravitational singularity in the centre of a black hole.

Published: March 2023

The active implementation of climate change projects, the latest resource- and nature-saving technologies, and environmental measures for the green growth of national economies require financial support. Currently, financial resources for environment-related investments and innovations are raised due to the increase of operational activities in banking institutions aimed at introducing green projects on the principles of environmental and socially responsible financing. This modern trend, known in the financial sphere as green banking, becomes relevant in countries where it is quite uncommon (for example, the Russian Federation and the Republic of Kazakhstan). The study aims at identifying the preferred tools for implementing the mechanism of green banking in Russia and Kazakhstan. The comparative analysis of expert opinions from Russia and Kazakhstan allows identifying both similarities and differences regarding the preferred instruments for providing monetary credits by green banking. However, the best lending rates for legal entities are considered the most preferable for experts from both countries.

The authors of the article conclude that the creation of a segment of green products and services in the financial market will serve not only the implementation of the green economy principles but also the formation of an effective environmental policy as a mechanism for implementing sustainable development goals supported by environmental financial policy.
“Green Products”: A Review with the Consumer Buying Process Framework
Authors: CAO Yanghui
Published: March 2023

Green consumption has become a crucial academic and practical topic with the increasing environmental-protection awareness of scholars, industries and consumers. However, the growth in green purchasing may not reflect the concerns. This study aims to synthesize recent research and points several causes of low purchases to green products in the consumer perspective and provide a comprehensive understanding to the realistic consumer decision-making process. Through the scope of Consumer Buying Process framework, this study systematically reviewed 73 credible articles on green purchase behaviour published from 2010 to 2022. Main constructs and theories applied in selected literature is further discussed in each sector of the CBP framework. The study results showed the green purchase process may have a ‘loop tendency’ that falls into the circulation of construction of evaluation and adoption of those evaluations. Moreover, purchasing behaviour which performed by minority of the consumers may not be strong enough to form a valid social norm, and the current available still lacked power to fulfil consumer needs. With the modified consumer buying process framework, this study highlights the importance of creating memorable experience and build strong emotional communications with consumers.
The Extent of Considering Environmental Crimes as a Manifestation of Economic Crimes
Authors: ALSHIBLE Mohamad , ABU ISSA Hamzeh , AL-BILLEH Tareq
Published: March 2023

The damage caused by environmental crimes may be hidden, but it greatly impacts life. Environmental violations are increasing in light of the great impotence that may characterize the legal systems to confront such crimes. At the international level, the legislation also has little effect because of the continued expansion of the circle of environmental crimes. On the other hand, economic crimes face great interference from the concerned authorities. If we look at these crimes, we find that environmental crimes are more dangerous, not less or perhaps more than them, which opened the door to the question of the possibility of considering environmental crimes within the range of economic crimes to obtain the quality of strict legal procedures applied in the framework of environmental crimes, this is in order to achieve an effective response to environmental crimes. The study explained and treated it by achieving legislative and legal approaches between environmental and economic crimes. The study concluded that environmental offences should be prosecuted similarly to economic offences, just as economic crimes attracted the legislator's attention to developing legislation compatible with the seriousness of environmental crimes.

Published: March 2023

The increasing energy demand and the associated environmental pollution have attracted research in renewable energy production from organic resources and waste. Renewable energy resources can reduce greenhouse gas emissions and contribute to energy security. Anaerobic digestion (AD) is an environmentally friendly and effective technique for producing biogas from biomass. This biogas can be used to generate electricity, produce process heat and other energy uses. The Aspen Plus simulation model was used for the AD process for biogas production in this work, with an experiment for anaerobic digestion tank design. The effects of temperature and hydrogen flow at work, the acid content of raw materials, and the operating pressure on biogas production products were analyzed and optimized. The optimum production level for biomethane was 75 liters at the feed flow rate of 20%, a hydrogen flow rate of 180 liters/day, the pressure of 2.5 bar, pH value of 7, and the operating temperature value of 50°C.From the experiment, the results indicated that biofuels could be produced with a cumulative rate of 564.3 m3 and a daily production rate of 18.81 m3 from animal waste.

Published: March 2023

The results of the research show that in developed countries, where approximately 16% of the world’s population lives, more than 2 times more solid waste per capita than one Ukrainian, but more than half of this waste is subject to recycling and composting. The results of the correlation analysis have shown that the circular economies of Ukraine and EU countries are very closely connected. Accordingly, the increase in the level of the circular economy in Ukraine in the future will be able to positively affect the environmental situation of other countries of the world. But there are lenient administrative penalties and fines for environmental pollution in Ukraine, as well as low environmental fees, which, in turn, does not encourage producers to move to more expensive principles of circular production on the one hand and does not protect against violating government restrictions on the other hand. Besides, the situation with the development of the circular economy in Ukraine is relevant because of the aggression of the russian federation against Ukraine, when, due to the destruction of infrastructure, including critical one, there is a very strong shortage of energy resources, in particular during the winter period. The paper proposes to develop and implement in Ukraine a targeted comprehensive program for solid waste management, that should provide the main ways to achieve goals and objectives of after-war circular economy development

Cancer is the second largest cause of mortality worldwide. Many natural bioactive chemicals generated from plants have favorable impacts on health, including cancer chemoprevention, compared to their manufactured counterparts. Persicaline, a novel sulfur-containing imidazoline alkaloid derived from Salvadora persica, has been shown to display promising antioxidant activity. In this study, the antiproliferative activity of persicaline was tested against different cancer cells using (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide assay. The cell death mode and cell-cycle arrest were examined using flow cytometry analysis. In addition, the proapoptotic and molecular mechanism effects of persicaline against mammary MCF-7 cell line were explored. Furthermore, the impact of persicaline on apoptotic genes markers, generation of reactive oxygen species (ROS), and mitochondrial membrane potential were monitored. It was found that persicaline inhibits cell proliferation in a dose-dependent manner. Persicaline-treated MCF-7 cells also showed initiation of apoptotic events and G1 cell-cycle arrest. In addition, persicaline treatment led to an increase in ROS generation, Bax and caspase upregulation while the Bcl-2 was downregulated. Hence, for the first time, this study showed that persicaline causes G1 phase arrest and apoptosis induction in MCF-7 cells. Increased proapoptotic genes and ROS levels were required for the antiproliferative and apoptotic effects of persicaline.

Authors: Lin Zhenzhen , Chen Xianlei , Lu Lu , Yao Xin , Zhai Chunyang , Tao Hengcong
Published: March 2023

Catalytic synthesis of value-added chemicals from sustainable biomass or biomass-derived platform chemicals is an essential strategy for reducing dependency on fossil fuels. As a precursor for the synthesis of important polymers such as polyesters, polyurethanes, and polyamides, FDCA is a monomer with high added value. Meanwhile, due to its widespread use in chemical industry, 2,5-furandicarboxylic acid (FDCA) has gained significant interest in recent years. In this review, we discuss the electrochemical oxidation of 5-hydroxymethylfurfural (HMF) and summarize the most recent advances in electrode materials from the past 5 years, including reaction mechanisms, catalyst structures, and coupling reactions. First, the effect of pH on the electrocatalytic oxidation of furfural is presented, followed by a systematic summary of the reaction mechanism (direct and indirect oxidation). Then, the advantages, disadvantages, and research progress of precious metal, non-precious metal, and non-metallic HMF electrooxidation catalysts are discussed. In addition, a coupled dual system that combines HMF electrooxidation with hydrogen reduction reaction, CO2 reduction, or N2 reduction for more effective energy utilization is discussed. This review can guide the electrochemical oxidation of furfural and the development of advanced electrocatalyst materials for the implementation and production of renewable resources.

Inequity In Corrective Eyewear Insurance In Ontario: A Repeated Cross-Sectional Study
Authors: Guindon Emmanuel , Guo Elaine , Abbas Umaima , Ernest Pranipa , Sweetman Arthur
Published: March 2023

Background 

Although the lack of vision insurance coverage has been linked to adverse vision outcomes, Canada still has a patchwork system that provides poor or no coverage to many of its residents. 

Data and methods 

We used data from the Canadian Community Health Survey (2005, 2008, 2013-2014) and logistic regressions to describe the extent to which Ontario residents reported insurance coverage for corrective eyewear after the delisting of routine eye examinations for healthy adults in 2004; and, to examine associations between socioeconomic and demographic characteristics, self-reported health and insurance coverage for corrective eyewear. 

Results 

We found important socioeconomic differences in the reporting of corrective eyewear insurance. Lower-SES adults were more likely to have reported public corrective eyewear coverage, whereas higher-SES adults and older adults were more likely to have reported private coverage. Overall, lower-SES adults and older adults were substantially less likely to have reported any corrective eyewear coverage. Adults and older adults in poorer health had lower odds of having reported private coverage for corrective eyewear. Relative to 2005, adults had higher odds of having reported public coverage, while older adults had lower odds of having reported public coverage for corrective eyewear in 2013 and 2014. 

Interpretation

Our findings reinforce the limits of the current patchwork insurance system for eye care and eyewear in Ontario. The substantial socioeconomic differences in the reporting of corrective eyewear insurance, as well as the low coverage in older adults, particularly among the poor and unhealthy, are of concern.
Musculoskeletal Pain Among Community-Dwelling Older Adults during the COVID-19 Pandemic: A Longitudinal Survey
Authors: Almeida Lisandra
Published: March 2023

OBJECTIVE: To describe the MSK pain prevalence and incidence and identify factors associated with MSK pain among older adults over a 1-year follow-up during the COVID-19 pandemic.
 
METHODS: This longitudinal telesurvey recruited community-dwelling older adults (less than or equal to 65 years) in Hamilton, Canada. MSK pain prevalence and incidence were calculated. Multilevel negative binomial and ordered logistic regression models were used to identify factors associated with the number of pain sites (0 to 7 pain sites), and most intense pain (no, mild, moderate, and severe pain).
 
RESULTS: We included 247 participants. Pain prevalence ranged between 64% at baseline to 73% at one year. The interaction of mental health by time as well as age and mobility were associated with the number of pain sites. Being older (IRR 0.96; 95% CI 0.94 to 0.98) and having better mobility (IRR 0.96; 0.95 to 0.96) were associated with lower number of pain sites. Having better mental health was associated with higher numbers of pain sites at 6- (IRR 1.58, 95% CI 1.05 to 2.37), 9- (IRR 1.55, 95% CI 1.02 to 2.34), and 12-months follow-ups (IRR 1.66, 95% CI 1.10 to 2.53). Sex, BMI and interactions of age by time, mobility by time, and mental health by time interaction were associated with the most intense pain. Being male (OR 0.87; 0.82 to 0.93) and having a greater BMI (OR 1.07; 1.00 to 1.14) were associated with lower and higher pain intensity, respectively. Being older (OR 1.09; 1.01 to 1.18) and having better mobility (OR 1.06; 1.01 to 1.11) were associated with higher pain intensity at 12 months.
 
CONCLUSION: Older adults were found to have high MSK pain prevalence, however, there was not a significant increase over time. Our results demonstrated that mobility, age, BMI, sex, and mental health are important factors associated with MSK pain in older adults.
COMPARISON OF DIFFERENT SOLID PHASE MICROEXTRACTION FIBERS IN EXTRACTION OF VOLATILE COMPOUNDS FROM ADIPOSE TISSUE
Authors: GÜLER Zehra , DURSUN Ahmet
Published: March 2023

The volatile compounds (VCs) in headspace of adipose tissues (perirenal, tail, caul) were extracted by solid-phase microextraction (SPME) fiber coated with carboxen/ polydimethylsiloxane (CAR/PDMS) or divinylbenzene/ carboxen/ polydimethylsloxane (DVB/CAR/PDMS). In extraction with CAR/PDMS coating compared to DVB/CAR/PDMS, more VCs were obtained in perirenal (53 versus 41), tail (51 vs 47) and caul (35 vs 33) fats. Increased retention index for aldehydes increased the adsorption on DVB/CAR/PDMS. This fiber also provided a good yield for carboxylic acids. CAR/PDMS fiber could be recommended for VCs from adipose tissues if the goal is to identify aldehydes, especially fatty acid oxidation products and low molecular weight hydrocarbons, as well as greater number of VCs. However, in case of targeting carboxylic acids, esters, and also high molecular weight aldehydes, DVB/CAR/PDMS could be utilized due to its high affinity for mentioned compounds. Furthermore, the optimum extraction time should be studied to determine the time for VCs to reach equilibrium.

The COVID-19 pandemic has caused problems in learning tahfidz Al-Qur'an in Indonesia. One of the issues is how to keep the accuracy of reading the Qur'an related to lip movements and makharij letters which should be held through talaqqi (face-to-face) method but now it is conducted in virtual learning. This paper aims to analyze the innovation of tahfidz Al-Qur'an learning in Indonesia during the COVID-19 pandemic. This research uses qualitative data taken from observations and in-depth interviews. The research involves students, educators, and school principals. The data are analyzed using the triangulation technique based on a phenomenological mindset. The results show that (1) the learning of Al-Qur'an tahfidz during the pandemic is conducted online using supporting media technology that can accommodate, integrate, and unify the management of Al-Qur'an tahfidz learning; (2) Al-Qur'an tahfidz learning innovation can solve the existing problems by paying attention more to lip and tongue movements and sounds that the students produce, and; (3) Al-Qur'an tahfidz learning innovation has positive implications for the student's knowledge and skill competencies with satisfactory results. Their good outcomes may also be much better with the improvement of their attitudes in learning. This research suggests further research by developing a virtual tahfidz learning method to provide other alternatives to the tahfidz learning method during the COVID-19 pandemic.

The perkumpulan alam hijau (A-HI) is a form of non-formal education that organizes various training activities and is located in Jambi City.  One form of training held is infographic video-making training. So far, the training activities given to students are the delivery of material through power points. The final results of the training activities provided by delivering material through power points are not optimal. Therefore, it is necessary to carry out media development solutions in the delivery of training materials using adobe flash premiere cs6. This study aims to develop a medium for delivering material for making infographic videos based on adobe premiere cs6 using the analysis, design, development, implementation, and evaluation (ADDIE) model. The results showed that the training material for making infographic videos using adobe premiere cs6 was effective as shown by the results of an assessment conducted by multimedia experts based on three aspects, namely display, operation, and interaction. The percentage of the results of the assessment of the three aspects is 91%, with the highest percentage being in the operational aspect at 93% and followed successively by the interaction aspect (92.20%), and the display aspect at 87.40%.  Meanwhile, the assessment carried out by the training participants was seen from four aspects, namely benefits, appearance, interaction, and independent learning. The percentage of the four aspects of an assessment is 88.10% with the largest percentage being in the interaction aspect, which is 92% and the lowest percentage is in the independent learning aspect, which is 80%.

Gender disparities still exist in the business world, yet things are slowly starting to change. Other than that, women have historically faced greater obstacles than men when it comes to achieving success in the business world. Women are becoming leaders in industries and achieving top positions in companies. This paper describes the result of need analysis of women's capacity development strategy among the actors of the community-based creative economy in tourism business. This qualitative approach used observation, interviews with focused group discussion activities, and document analysis as a method to collect data. It was carried out involving 25 women creative economy actors as informants. Business pattern dynamization emerged as one of the strategies to cope with socio-economic issues due to the pandemic, which was done by developing businesses in an agricultural field, fulfilling household needs, online ready-made garments, and opening a business at the beach. The community serves as a social capital that helps creative economy actors in this study overcome hindrances, such as high-interest loans, price war, and unhealthy competition. Hence, these women embody the qualities of resilience, determination, and grit. They prove that with hard work and dedication, anything is possible.

The conditions above illustrate how the Indonesian nation has lost its character as a nation that upholds noble values. However, on the other hand, in a multicultural Indonesian society, some still maintain the existence of noble values inherited by their ancestors. These noble values are guarded and maintained through customary law, which is obeyed with full awareness. Thus, customary law can be the basis for character education, as found in customary law in Bayan Village, North Lombok, and West Nusa Tenggara Province (NTB). The purpose of this study is to describe customary law in Bayan Village, North Lombok, West Nusa Tenggara Province, as a basis for character education. The specific objectives are (1) identification of various types of customary law in Bayan Village as a basis for character education and (2) identification of character values in customary law in Bayan Village. These findings are significant for learning innovations that are contextual and oriented in character strengthening. Data were collected using interviews, observation, and documentation techniques. Data analysis used qualitative analysis with the stages of data reduction, data presentation, verification, and conclusion. The results of the study show that (1) there are various types of customary law in Bayan Village that can be the basis of character education, namely customary law for forest conservation and spring, as well as customary law of Marriage, (2) character values contained in customary law in Bayan village includes: care for the environment, democracy, hard work, and religious. These values are part of the values developed in character education, so they can be the basis of character education.
Effects of Feeding with Non-Autoclaved and Autoclaved Fructose-Arginine Mixture on Stress Resistance of Drosophila Melanogaster

The diet of modern people includes fast food that leads to the development of obesity and related diseases. One of the reasons for the negative impact of such a diet is advanced glycation end products (AGEs), substances formed as a result of the interaction of amino acids with carbohydrates, especially under the influence of high temperature (the Maillard reaction). Once in the body, these substances lead to oxidative stress and inflammation, which in turn can accelerate aging process. Also, AGEs are involved in the development of metabolic syndrome, diabetes, cardiovascular disease, and cancer. However, mild oxidative stress can activate cellular defense systems and make cells more resistant to a stronger oxidative stress or other types of stress that is called hormesis or cross-tolerance. Our study shows an effect of non-autoclaved (FAMn) and autoclaved (FAMa) fructose-arginine mixtures on the body of fruit flies. In our study, we used the Drosophila melanogaster line w1118. Flies were grown on nutrient medium with the addition of different amounts of FAMn or FAMa to the final concentrations of reagents in a mixture of 10, 20 and 100 mM and maintained on the respective media until the second day of age. The flies were then used to determine physiological and biochemical parameters. The increase in absorbance at 294 nm and 420 nm and a decrease in fructose concentration in FAMa indicated that autoclaving of the fructose-arginine mixture led to caramelization of fructose and formation of Maillard products. The study showed that FAM in both forms did not affect lipid peroxide level, a marker of oxidative stress. Also, FAM in both forms did not affect the resistance of flies to hydrogen peroxide. However, FAMn, but not FAMa, increased the resistance of flies to sodium nitroprusside (SNP). This effect is likely caused by the presence of arginine, a substrate for NO-synthase, which may pre-adapt flies to •NO released from SNP. FAMn and FAMa at the concentration of 100 mM increased content of storage lipids, but decreased resistance of flies to starvation.
