Deep Learning Algorithm for Optimization of Wait Time at a Traffic Signal Controlled Intersection for Smart Traffic Management
Authors: Sura Sahil , Gupta Himmi
Published: January 2024

Abstract: The urban landscape is constantly shifting and adapting as a result of factors such as population increase, immigration, and changes in the economy, politics, and culture. Concerns like growing road obstruction, transit delays, pollution levels, consumption of gasoline, etc. have resulted from higher traffic volumes in metropolitan areas. Life expectancy, road safety, environmental quality, and commute times are all impacted by traffic congestion. At junctions, traffic lights play a crucial role in regulating vehicular flow. The traditional pre-timed traffic systems have been ineffective due to the dramatic growth in lights become insufficient in managing traffic clearance which leads to heavy traffic congestion at intersection. Another major issue is that the Emergency vehicles like ambulance, police van, fire brigade experience prolonged waiting time to cross the intersection. For these reasons, development of smart intersections with the aid of technologies such as fuzzy logic, neural networks, artificial intelligence, multiprocessor systems etc. can help to provide the solution and improve the urban traffic management problems. Smart cities are increasingly adopting solutions by using adaptive and intelligent approach to develop smart traffic lights to improve the traffic flow at intersections. The current study on smart traffic light system makes contribution in developing intelligent and adaptive systems to resolve traffic congestion problems at single and connected intersections with an objective to improve traffic clearance and prioritize passage of Emergency vehicle at an isolated intersection. Another problem is the one generally faced by pedestrians as they have to wait for a prolonged interval of time for getting way to cross the lane of major intersection specially at peak traffic hours. This problem has also been considered in the study. System performance has been tested for a twenty-four-hour traffic pattern at an isolated intersection. The outcomes of the simulations showed that the suggested design outperformed the standard fixed-time method in terms of automotive clearing, rescue vehicles passing, and pedestrians wait time.
The complexity of quantum support vector machines
Authors: Gentinetta Gian , Thomsen Arne , Sutter David , Woerner Stefan
Published: January 2024

Quantum support vector machines employ quantum circuits to define the kernel function. It has been shown that this approach offers a provable exponential speedup compared to any known classical algorithm for certain data sets. The training of such models corresponds to solving a convex optimization problem either via its primal or dual formulation. Due to the probabilistic nature of quantum mechanics, the training algorithms are affected by statistical uncertainty, which has a major impact on their complexity. We show that the dual problem can be solved in O(M4.67/ε2) quantum circuit evaluations, where M denotes the size of the data set and ε the solution accuracy compared to the ideal result from exact expectation values, which is only obtainable in theory. We prove under an empirically motivated assumption that the kernelized primal problem can alternatively be solved in O(min{M2/ε6,1/ε10}) evaluations by employing a generalization of a known classical algorithm called Pegasos. Accompanying empirical results demonstrate these analytical complexities to be essentially tight. In addition, we investigate a variational approximation to quantum support vector machines and show that their heuristic training achieves considerably better scaling in our experiments.

Reexamining “Free Energy Rate Density” as a Complexity Metric
Authors: Solis Ken
Published: January 2024

Cosmic Evolution, by Eric J. Chaisson is arguably one of the original “core” texts of big history. Despite being published over 20 years ago, it is still relevant for its explanation of the cosmological and thermodynamic underpinnings of the evolution of complex systems over the span of time. It was also a pioneering work because it proposed that we can quantify the degree of complexity of systems by determining the quantity of the “free energy rate density” or FERD (abbreviated as “Ωm” in Cosmic Evolution) that flows through a system. Although Chaisson advises that his correlations of FERD to complexity degree is subject to various limitations and generalizations, careful analysis of the arguments and examples used to support FERD indicates that it is even less likely to be as reliable and quantifiable than he purports for at least the following reasons:1. The author offers a relatively short list of criteria for a system to qualify being “complex” that in turn results in the inclusion of systems that are not classified as complex by usual criteria. 2. Free energy rate density is not compared against other complexity metrics and subsequently seems to serve as its own “gold standard.” The lack of comparisons results in a tautological argument and sometimes questionable conclusions.3. The argument for FERD sometimes deviates from the hypothesis that FERD is a good way to measure the degree of a system’s complexity to a claim that it also measures complex functions and structures as well. 4. The FERD that he reports are often actually for the total energy flow through a system. Hence, a much more efficient complexity might only appear to be less complex. 5. Complex systems have many variables that can confound attempts to make reliable and precise generalizations, including good metrics for their degree.

Published: January 2024

Transfer pricing is a company’s decision to determine the transfer of the prices of goods, services, and transactions implemented by the company (Choi et al., 2020). This study aimed to examine the effect of sustainability reporting, transfer pricing, and deferred tax expense on tax avoidance. This research was a descriptive quantitative study in which data were collected, processed, presented, and analyzed quantitatively (numbers) and descriptively (sentence description). This study was conducted in 35 multinational companies in the manufacturing sector listed on the Indonesia Stock Exchange (IDX), which were selected purposively. The observation period in this study was from 2016 to 2020. The analysis used in this research was panel data regression. The results showed that transfer pricing had an effect on tax avoidance, which means that if the company carries out transfer pricing, the company is indicated to be carrying out tax avoidance. Sustainability reporting and deferred tax expense cannot affect tax avoidance, which means that if companies carry out sustainability reporting and have a deferred tax expense they are not indicated to do tax avoidance.
Effectiveness of inosine pranobex in the treatment and prevention of infectious diseases (system review)
Authors: Babachenko I. V.
Published: January 2024

The purpose of the article is a systematic review of studies conducted in recent decades in children and adults, with an emphasis on domestic works, on the use of inosine pranobex preparations, in the treatment of infectious diseases. The clinical and immunological effectiveness of inosine pranobex in the treatment and prevention of relapses in patients with recurrent respiratory viral infections against the background of persistent herpesviruses types 4-6 has been demonstrated. Using the example of multicenter comparative as well as placebo-controlled studies, not only the effectiveness, but also the safety of long-term courses of therapy is shown. A promising direction is the use of inosine pranobex in the treatment of COVID-19 and post-Covid conditions, taking into account its immunomodulatory effect without the risk of increasing the “cytokine storm”, as well as studies of the direct antiviral effect on the SARS-CoV-2 virus in vitro.
Restrukturyzacja sektora mleczarskiego w Polsce. Przyczyny i skutki
Authors: Malak-Rawlikowska Agata , Fałkowski Jan , Milczarek-Andrzejewska Dominika
Published: January 2024

W artykule przedstawiono proces restrukturyzacji sektora mleczarskiego w Polsce. Na podstawie danych statystycznych oraz badań jakościowych przeanalizowano najważniejsze zmiany, które nastąpiły w poszczególnych segmentach tego sektora. Szczególnie dynamiczny proces charakteryzował segment produkcji i przetwórstwa mleka. Obok zmian w strukturze, jakości oraz marketingu mleka i produktów mleczarskich, przeobrażeniu uległo także otoczenie instytucjonalne, w którym działają rolnicy oraz mleczarnie. Dostosowania w gospodarstwach rolnych były stymulowane w znacznym stopniu przez przetwórców, których dostosowania wynikały z kolei z procesu integracji z Unią Europejską, a wśród nich należy wskazać przede wszystkim wzrost wymagań jakościowych oraz konieczność działania na rynku krajowym i eksportowym. Dodatkowo, wprowadzony system kwotowania produkcji mleka jest, zdaniem autorów, jednym z najważniejszych czynników determinujących tempo i zakres przyszłej restrukturyzacji.

Wewnętrzne uwarunkowania rozwoju polskiego rolnictwa
Authors: Ziętara Wojciech
Published: January 2024

Przedstawiono wewnętrzne uwarunkowania rozwoju rolnictwa w Polsce na tle wybranych krajów Europy zachodniej. Dokonano oceny zasobów ziemi. Wskazano, że w porównaniu do wybranych krajów powierzchnia użytków rolnych w przeliczeniu na jednego mieszkańca należy do wyższych w Europie. Zasoby pracy są również bardzo wysokie, zbyt wysokie w stosunku do potrzeb. Także wyposażenie w siłę pociągową jest wysokie. Aktualny poziom zasobów czynników produkcji to silne strony polskiego rolnictwa. Słabą stroną polskiego rolnictwa jest niska średnia powierzchnia gospodarstw rolnych, kilkakrotnie niższa niż w porównywanych krajach. Pozytywnym zjawiskiem jest wzrost udziału ziemi w gospodarstwach o większej powierzchni, powyżej 20 ha użytków rolnych. Stwierdza się terytorialne zróżnicowanie produkcji zwierzęcej. Następuje specjalizacja regionalna. Ponad 50% pogłowia krów i trzody chlewnej skupiona jest odpowiednio w pięciu i trzech województwach.
PCAOB International Inspections and the Market Value of Cash Holdings
Authors: Liu Yiye , Yu Yangxin , Zhu Xindong
Published: January 2024

This study examines whether and how Public Company Accounting Oversight Board (PCAOB) international inspections mitigate the market value discount in cash holdings. We find that shareholders value internal cash holdings more highly for the non-U.S.-listed clients of inspected auditors after the public disclosure of the auditors’ inspection reports. We show that the decreased agency frictions and the increased financial reporting credibility are potential mechanisms. Further, we find that the effect of PCAOB international inspections on the market value of cash holdings is stronger in countries with weaker legal institutions and less sound information environment. Since investors’ valuation of cash mirrors how they expect the cash to be used, our results suggest a unique role of PCAOB oversight in mitigating unresolved agency problems and safeguarding corporate resources, thereby lessening investors’ markdowns of cash assets. Our findings help identify the real economic impacts of PCAOB oversight in enhancing global stock market confidence.

KD025 is a casein kinase 2 inhibitor that protects against glucolipotoxicity in beta cells
Authors: Devkota Ranjan , C. Small Jonnell , Carbone Kaycee , A. Glass Michael , Vetere Amedeo , K. Wagner Bridget
Published: January 2024

Glucolipotoxicity (GLT), in which elevated levels of glucose and fatty acids have deleterious effects on β-cell biology, is thought to be one of the major contributors in progression of type 2 diabetes. In search of novel small molecules that protects β-cells against GLT, we previously discovered KD025, an inhibitor of Rho-associated coiled-coil containing kinase isoform 2 (ROCK2), as a GLT-protective compound in INS-1E cells and dissociated human islets. To further understand the mechanism of action of KD025, we found that pharmacological and genetic inhibition of ROCK2 was not responsible for the protective effects of KD025 against GLT. Instead, kinase profiling revealed that KD025 potently inhibits catalytic subunits of casein kinase 2 (CK2), a constitutively active serine/threonine kinase. We experimentally verified that the inhibition of one of the catalytic subunits of casein kinase 2, CK2A1, but not CK2A2, improved cell viability when challenged with GLT. We conclude that KD025 inhibits CK2 to protect β-cells from glucolipotoxicity.

REFLECTION OF NON-MATERIAL VALUES BEHIND TAKJIL ACCOUNTING PRACTICES: A STUDY OF ISLAMIC ETHNOMETHODOLOGY
Authors: Thalib Mohamad
Published: January 2024

This research departs from the problem of the rise of accounting studies that focus on the corporate realm and ignore non-material values in it. This study aims to reveal the non-material values behind takjil accounting practices. This research uses the Islamic paradigm. The researcher chose this paradigm because the Islamic paradigm recognizes that accounting consists of material and non-material elements. The approach used in this study is Islamic ethnomethodology. There are five data analysis stages: charity, knowledge, faith, revelation information, and courtesy. The results of the study show that there are four accounting practices, namely cost accounting incurred by donors and mosque administrators, accounting for spiritual and emotional benefits obtained by donors when giving iftar at the mosque, simple accounting recording methods carried out by mosque administrators when receiving funds infaq from donors, and accountability for infaq costs provided by donors. The accounting practice is conditioned by non-material values in the form of sincerity, helping, and responsibility. The conclusion of this study reinforces that the essence of accounting is not only in the realm of companies but in everyday life, including when carrying out iftar activities at the mosque. Practiced accounting is not limited to material, but there are non-material values that play an essential role in shaping accounting practice.

Konceptualizace bezpečnostně-rozvojového nexu: současné interpretace a kritika
Authors:   University of West Bohemia, Rod Zdeněk
Published: January 2024

The security-development nexus (SDN) has gained prominence in international relations since the 1990s, undergoing significant theoretical and practical transformations in conflict resolution. It is generally viewed as a relationship between security and development, with two primary perspectives: one where security precedes development and another where they progress hand in hand. The SDN's theoretical foundations have been translated into practical policies, emphasizing human security and post-conflict reconstruction. However, it faces criticism from those who argue that security and development are inherently incompatible. In response to the diverse and contentious debate surrounding SDN, this paper aims to provide Czech scholars and students of International Relations and Security Studies with a comprehensive overview. It synthesizes the core arguments of international relations scholars across various theoretical and cultural backgrounds and practice-oriented literature. The article examines how recent discussions have shaped the SDN concept and highlights key author differences. Over the past three decades, the SDN has evolved dynamically and offers valuable insights into resolving past and ongoing armed conflicts. Additionally, the article discusses the security-development nexus in the Czech academic context, which has been largely absent, with only a few exceptions.

Impact of a small storage reservoir on the hydro-chemical regime of a flysch stream: A case study for the Korzeń stream (Poland)
Authors: Fudała Wioletta , Bogdał Andrzej , Kowalik Tomasz
Published: January 2024

The paper presents in form of a case study the results of 10-year long hydro-chemical studies on the Korzeń stream on which the “Skrzyszów” small storage reservoir was built. Studies aimed at evaluating the impact of the reservoir on the surface water quality in a Flysch stream. The basis for the analysis was results of 21 hydro-chemical water quality parameters, from the following groups of indicators: physical and acidity, oxygen and organic pollution, biogenic, salinity, metals. Indicators were determined in one-month intervals in two periods: 2005–2009 (before the reservoir was built) and 2015–2019 (after the reservoir was built). Obtained results were subjected to a statistical analysis. The trend analysis of changes was performed using the Mann–Kendall test or the seasonal Kendall test; significance of differences between indicator values from two periods was evaluated using the nonparametric Mann– Whitney U test. Results of analysis showed significant change trends of water quality parameters, in case of total iron concentration the trend was downward in both periods. Statistically significant differences between the values of definite majority of indicators were found in two analysed periods, indicating both favourable and unfavourable impact of the reservoir on water quality in the stream. Construction of the storage reservoir resulted in a significant change of physical and chemical indicators of water flowing in the stream. Random variation dynamics as well as tendencies and trends of changes over time have changed. In addition to modifying the stream hydro-chemical regime, the reservoir also affected the social and natural conditions.
Interaction of surface water and groundwater in Nida valley, Poland
Authors: Phan Cong Ngoc , Strużyński Andrzej , Kowalik Tomasz
Published: January 2024

The study area of the Nida valley was examined to investigate variations in groundwater and surface water levels, as well as the interaction between them. In the valley, there were three branches. The two actives were the Nida River itself and the Smuga Umianowicka branch while the Stara Nida branch was dry during the measurement session. Over a 12-month period from June 2021 to June 2022, 7 monitoring points were equipped with piezometers, comprising 5 groundwater points and 2 surface water points. The monitoring frequency was set to 30 minutes. The results of this research indicate that there are significant differences in the water level at the same observed point at different times. This study demonstrates seasonal changes in both surface water and groundwater levels with higher levels in autumn and winter and lower levels in spring and summer, which are closely tied to the changes in meteorological conditions during the research period, such as precipitation and air temperature. The study results also indicate that during summer and winter at the Nida River and its riparian area, losing stream is the primary process occurring in the studied reach. Conversely, during autumn and spring, the main process is gaining stream. At the human-maintained Smuga Umianowicka branch and in its riparian area, losing stream is the main process during summer and autumn, and gaining stream is the main process during spring. During winter, losing stream and gaining stream processes can occur simultaneously, and neither process takes place mainly.
Dendrometric evaluation of Helianthus annuus under water deficit conditions
Authors: Obročník Oliver , Bárek Viliam
Published: January 2024

Drought is characterised as a recurring climatic phenomenon with prolonged duration, affecting land through below-average rainfall and often accompanied by high temperatures. When the available water falls below the optimum level, water deficit or water stress arises, disrupting normal plant processes. This condition poses challenges for plant growth and development as it hampers the internal water transport, induces stomatal closure, and limits access to photosynthetic resources. The study employed the annual sunflower as the experimental plant. The plants were cultivated in a controlled environment with a temperature ranging from 20 to 25°C and a humidity level of 55 to 60%, supplemented by MARS HYDRO artificial LED lighting set to a 12-h photoperiod. Radial changes in the plant stems were monitored using a DD-S type dendrometric sensor to measure radial fluctuations. The collected data were recorded in a dendrometric data logger DL 18. Data collection occurred at hourly intervals from February 20 to March 9, 2023. The nine plants were divided into three groups, each comprising three plants. All plants from groups 1 and 2 received irrigation at one- day intervals (group 1 – 80 cm 3 per plant, group 2 – 40 cm 3 per plant) and group 3 was not irrigated. Based on these findings, visible water stress was evident in the plants under experimental conditions. Consequently, continuous monitoring throughout the growing season will be essential to adjust the irrigation rate to meet the requirements of the plants.
Changes within permanent grasslands used for agriculture in the West Pomeranian Voivodship
Authors: Kitczak Teodor , Podlasiński Marek , Jarnuszewski Grzegorz , Malinowski Ryszard
Published: January 2024

The study of changes in grassland was conducted on the territory of individual counties of the West Pomeranian Voivodship. Based on data collected in the Valorisation of the Agricultural Production Space of Poland and spatial data (an electronic 1:5000 soil and agricultural map) the basic information on the use of agricultural land in the 70s of the 20th century. Changes in use over time were analysed based on data the Statistics Poland (Pol.: Główny Urząd Statystyczny – GUS), General Geographic Database and The Agency for Restructuring and Modernisation of Agriculture Crop Register (Pol.: Agencja Restrukturyzacji i Modernizacji Rolnictwa – ARiMR). The studies showed that in the West Pomeranian Voivodship, a successive decrease in the share of permanent grasslands (0.9%) and arable lands (1.4%) is observed. There is a spatial variation in the share of permanent grassland in the province’s counties, with a distinction between northern and southern counties. The main direction of change in grassland area is arable land, which applies to counties with the highest share of permanent grassland (PG) and counties with a high share of the best soils and forest direction. Land quality was the main factor determining the direction of grassland changes, with the best PG converted to arable land or for investment purposes. In contrast, the weakest were converted to forestry or spontaneously wooded through abandonment. The main reasons for changes in grassland areas in the West Pomeranian Voivodship were: conversion of use to arable land, afforestation of grasslands, land use for urban planning purposes, leaving land fallow and conversion for constructing fishponds.
Moisture content of peat-moorsh soils with special attention to periods of drought
Authors: Oleszczuk Ryszard , Jadczyszyn Jan , Urbański Janusz , Zając Ewelina , Brandyk Andrzej , Niedźwiecki Jacek
Published: January 2024

The paper presents the course of variability of the moisture content of the top layers in shallow (45 cm) and medium-deep (90 cm) peat-moorsh soil profiles in the years 2015–2019 against the background of the same meteorological conditions and a similar level of the groundwater table. The relative precipitation index ( RPI) classifies the years 2015 and 2016 as dry, 2017 as wet, and 2018 and 2019 as average. For periods of atmospheric droughts, the average daily climatic water balance ( CWB) ranged from –5.30 to –1.35 mm∙d –1. The water table did not fall below 90 cm b.g.l. during the entire study period, and the range of its fluctuations was 8 cm greater in the shallow than in the medium-deep profile. The range of moisture at different depths varied significantly and ranged from approx. 6% in periods of drought to about 80% in wet periods. Soil moisture throughout the measurement period was above the plant available water range (p F > 4.2). The occurrence of soil drought in the shallow peat-moorsh soil profile had a range of up to 40 cm, and in the medium-deep profile of up to 30 cm. The sequence of no-precipitation days and the maximum amount of daily evapotranspiration during them determine the possible timing of drought; however, it is the precipitation distribution in individual months, considered in the current CWB values, that ultimately determine the formation of soil water resources at the research site.
Assessment of technological simulation of an agricultural biogas installation using integration mechanisms
Authors: Wałowski Grzegorz
Published: January 2024

The article presents technological and measurement systems and methods for substrate preparation, production and purification of raw biogas, biogas storage, cogeneration, and processing of post-fermentation mass. Based on the existing infrastructure for biogas production from pig slurry, a model system for integrating objects in the AVEVA environment using integration mechanisms was demonstrated. The simulation used an imaging method, and the 3D model was used for technological simulations. The work presents simulation results that allow us to understand the availability of graphic imaging techniques at each stage, define and expand the library of typical errors and requirements for pipeline installations, structures and devices, facilitating the identification of design errors and accelerated introduction of corrections to the installation design. The article features the use of integration of elements of a pilot biogas production installation in the AVEVA environment – innovative systems for heating the substrate and managing agricultural biogas production were implemented. A node for the production of raw biogas was indicated for the transport system of biogas produced in the fermentation tank, along with devices enabling the conduct, control and regulation of the fermentation process. The visualisation concerned integration of the biogas production technology diagram with the model environment for the created pipelines using integrator mechanisms.
Recognition of the vibriosis risk in Polish coastal waters of the Baltic Sea and public engagement in its mitigation
Authors: Piwowarczyk Joanna , Rakowski Marcin , Mytlewski Adam
Published: January 2024

The surface water temperature in the Baltic Sea has been growing as a consequence of broader changes of the Earth’s climate, which contributes to the proliferation of natural bacterioplankton and new types of bacteria, such as Vibrio vulnificus, in the region. This pathogenic bacterium finds optimal conditions for growth primarily in warm brackish waters. Places particularly vulnerable to these bacteria include shallow Baltic coastal waters where the proliferation of Vibrio strains increases in summer. The growing temperature of coastal waters boost this phenomenon, posing a serious threat to human health and the coastal Baltic tourism. The BaltVib project implemented by marine microbiologists investigates the impact of the so-called “system engineers”, e.g. mussels, macroalgae, and seagrass, on the diversity and abundance of vibriosis. The research should help to develop strategies to mitigate the problem of excessive populations of vibriosis through nature-based solutions. In addition to environmental and health issues, public awareness of the phenomena and future threats are equally important and these are also addressed in the project. The article presents results of a survey conducted on the Polish coast involving 140 respondents interviewed concerning their awareness of the increasing population of pathogenic vibriosis. The survey helped to diagnose how local residents perceive the threat to human health posed by Vibrio vulnificus now and in the future, as well as possible impacts these bacteria might have on economic use of the coastal waters. The survey also investigated the level of acceptance for various methods used to mitigate negative environmental changes.

Authors: Jakubowska Blanka
Published: January 2024

The goal of this paper has been to add an experimental data set for drying a meat product and provide a comparison with well-established thin-layer drying models. This article presented experimental investigations on the convective drying of Polish sausage slices at a temperature of 40°C. Slices have been in the thickness of 3 to 8mm. Measurements of mass loss and size change were performed. The data have been presented in the form of standard drying kinetics. Additionally, the estimation of the diffusion coefficient according to the simplified graphical approach is made. Based on the best-fit approach the coefficients for typical semiempirical correlations for MR (moisture ratio) estimation have been calculated and presented.
The Use of Gaseous Ozone to Reduce the Microbial Load of Rhubarb (Rheum L.) Petioles as an Additive to Craft Wheat Beers
Authors: Zardzewiały Miłosz , Belcar Justyna , Gorzelany Józef
Published: January 2024

Rhubarb (Rheum rhaponticum L.) is a valuable source of active components responsible for laxative, antibacterial, diuretic, anti-inflammatory and anti-cancer properties. On the other hand, ozone being an allotropic form of oxygen, due to its potential is a powerful antimicrobial agent. Treatment of rhubarb petioles with gaseous ozone, especially at a concentration of 50 ppm, for 30 minutes had a positive result on the microbiological stability and quality of the finished material. Sensory evaluation of prepared beers enriched without ozonated and ozonated rhubarb pulp showed that wheat beer with the addition of ozonated (50 ppm) rhubarb pulp was characterized by a balanced aroma and taste. The physico-chemical analysis of wheat beers demonstrated that the increasing concentration of ozone had an impact on, among others, increased the degree of final real attenuation (by 21.97%), decreased pH (by 18.43%) and energy value (by 36.30%), but had a negative impact on the content of ethyl alcohol (by 17.32%) compared to the control beer. Among the analyzed beers enriched with rhubarb, the beer product with the addition of ozonated (50 ppm) rhubarb was the most microbiologically stable. The research shows that wheat beers enriched with fragmented rhubarb can be a new trend to expand the range of wheat beers, and the use of gaseous ozone, especially at a concentration of 50 ppm for 30 minutes, can be a trend to extend the microbiological stability of beers, especially craft beers.

The important role of plants in the prevention and treatment of several ailments has been known since ancient times. Plants are a rich source of biocompounds with known therapeutic benefits. At the moment, natural products are a hope for certain diseases that modern medicine fails to cure. Cancerous pathologies were and still are a disease category in which the most effective treatment with the fewest adverse effects is constantly being sought. Malignant melanoma is the skin cancer that has produced the highest number of deaths and is intensively studied. Galium verum L. is a plant known for its traditional uses, for this reason, it is currently being studied in the therapy of several diseases, including cancer. Our study aimed to phytochemically characterize the petroleum ether extract and to evaluate its safety and antitumor potential on HaCaT and A375 cell lines, respectively. The FT-IR assay revealed that the GvPE extract comprises functional groups of lipophilic compounds and phenolic compounds, four compounds being qualitatively identified: rutin, isoquercitrin, quercetol, and chlorogenic acid through LC-MS analysis, in addition, a medium antioxidant capacity was observed. The results obtained on HaCaT showed that GvPE does not significantly reduce cell viability, and up to the tested doses it does not produce a relevant cytotoxic effect. In the case of skin cancer cells, the concentration of 55 μg/mL revealed a viability percentage of up to 55%, the cells becoming round and detaching from the plaque. Finally, the nuclear evaluation exhibited that the GvPE extract has an apoptotic-like effect, with the production of nuclear fragmentation and chromatin condensation.

Published: January 2024

This study aimed to synthesize structured lipids containing high mono- and diacylglycerol by glycerolysisinteresterification of palm olein and coconut oil blend in two high-shear continuous stirred tank reactors in series. The result showed that various flow rates of 11 mL/min to 23 mL/min did not significantly increase mono- and diacylglycerol concentration, while at a flow rate of 26 mL/min only a low concentration of mono- and diacylglycerol was formed. However, a flow rate 20 mL/min and an agitating speed of 2000 rpm produced mono- and diacylglycerol concentration of 61.7% with the highest productivity of 2.1%/min and a triacylglycerol conversion of 64.6%. The slip melting point, melting point, hardness, emulsion capacity, and stability were 23.77 oC, 30 oC, 14.6 N, 65.15%, and 59.15%, respectively. The product’s solid fat content at 25 oC was lower than cocoa butter. The product contained β’ and β crystals, thus it can be applied as a cocoa butter substitute.
