Comparision of Models on Basic Passive Circuit Components
Authors: Gülnahar Murat , Gür Müslüm , Babacan Yunus
Published: January 2025

Bu çalışmada, yüksek ve düşük dereceli temel pasif devre elemanları hakkında Chua ve Wang tarafından
oluşturulan modellerden bahsedilerek bunların avantajları ve dezavantajlarından mukayeseli olarak
bahsedilmektedir. Chua modelinde gerilim, akım, akı ve yük temel büyüklük olarak düşünülerek bu devre
elemanları karesel bir metodla yerleştirilmektedir. Buna karşın Wang modelinde ise, gerilim ve akımın temel
büyüklük olmadığı ve bundan dolayı karesel modelin tam manasıyla doğru olmadığı gerekçesiyle yeni bir model
ortaya konulmaktadır. Bu modele göre, sadece akı ve yük temel büyüklük olarak düşünülmekte ve üçgensel bir
model ile devre elemanları konumlandırılmaktadır. Ancak bu iki modelde de elemanların yerleştirilmesinde
bazı eksikler/hatalar bulunduğu için her iki modelin tam olarak doğru olmadığını düşünmekteyiz. Böylece her
iki modelin avantajları ve dezavantajlarının doğru olarak tanımlanmasıyla daha doğru bir modelin
oluşturulmasında önemli bir temel oluşturacağı düşüncesine ulaşmaktayız.

Authors: Salazar Lina , Tadeo Ruesta Diana Victoria , Alvarez Luis
Published: January 2025

Agricultural productivity has been a critical driver of economic growth in Latin America and the Caribbean (LAC) over the past six decades. However, while agricultural output is still rising, recent trends suggest a decline in agricultural productivity and an increasing reliance on input use, which could have harmful effects on the environment and natural resources. This study aims to analyze the historical trends of agricultural productivity in LAC while assessing the heterogeneous dynamics among subregions and countries, using a unique dataset compiled by the USDA, combined with FAO and ILO data for the period from 1961 to 2021. Agricultural productivity is essential for addressing LAC's interconnected challenges of poverty, food insecurity, and climate change. Hence, understanding its drivers is key to designing comprehensive policies to improve efficiency and ensure long-term sustainable development across the region.

Selected Acoustic Features of the Welsh Lateral Fricative /ɫ/
Authors: Baran Michał
Published: January 2025

The Welsh language exhibits a number of features uncommon from a cross-linguistic point of view, one of which is a relatively large number of fricative phonemes. This paper analyses selected acoustic features of the Welsh lateral fricative /ɬ/ in order to contribute to the debate on the laryngeal system in Welsh and the classification of /ɬ/ within that system. Total articulation length, voicing length and SMA parameters of the friction period are measured and analysed on the basis of recordings of 6 native speakers of Welsh. The results confirm the classification of /ɬ/ as a fortis sound proposed in earlier studies (Asmus and Grawunder 2017, Baran forthcoming) and suggest that the Welsh /ɬ/ may exhibit aspiration.
Effect of Different Photo-sensitive Nets on the Colour of Apple Cv. Florina
Authors: Pashova Teodora , Tabakov Sava , Mihaylova Emilia
Published: January 2025

Background: Photo-selective shade netting technology is an emerging agro-technological concept, which aims at the improvement of crop quality by modification of spectral light and provides physical protection of the crop. The aim of this study was to investigate the influence of four protective nets with different colours on the colour of the apple fruits grown under the netting. Methods: The colour of apple fruits, variety Florina, grown under different photo-selective nets: black, red, white and yellow was studied. The colour of the fruits studied was determined in terms of hue, saturation and brightness. The effect of white reflective ground cover on colour of the apples was also investigated. For this purpose, the reflective ground cover was applied for the duration of one month, during the fruit ripening period. To determine the colour and its descriptive values, spectrophotometric measurements were carried out with a CSS-D spectrophotometer, equipped with a CSS-45 sensor from Gigahertz-Optic. The spectrophotometric measurements show that the dominant colour of the apples was-yellow and the covering colour of the skin of the fruit falls in the orange section of the spectrum. Result: As a summary of the obtained results, the most intense was the colour of apples, grown under a yellow net and the least intense was the apple colour when a white net and a reflective ground cover was used. It was found that, the colour of the apple skin, in terms of wavelength, significantly changes when a ground reflective cover was used. Noticeable differences in the intensity of the apple colour were found. The apple colour intensity was higher when only photo-selective nets were used. A deviation from this dependence was observed only for the black net. A correlation analysis was made between the spectral characteristics. The results show that there was strong, albeit negative, relationship between the half-width of the reflection peak and the rest of the spectral characteristics, the strongest being for the spectral colour of the apple fruit.

Financial Socialization and Behavior of Young Adults: Objective and Subjective Financial Knowledge as Mediators
Authors: Ramos Salazar Leslie , Solis Oscar
Published: January 2025

Throughout the COVID-19 pandemic, young adults around the world faced severe financial challenges. From this societal context, college-aged adults sought financial guidance from their families and peers to learn about financial matters to make informed financial decisions. Using financial socialization theory and the theory of household consumption behavior, we examined the antecedents of financial behavior and the mediating role of financial knowledge on financial socialization and financial behavior. Using a cross-sectional survey in a public, state institution in 2022, we analyzed data from 207 participants. Results supported the mediating effect of objective and subjective financial knowledge on the positive relationship between financial socialization and financial behavior. Additionally, household spending had a moderating effect on the relationship between objective knowledge and financial behavior. Findings yield important implications for education and financial stakeholders working with young adult consumers.
The Role of COVID-Related Socioeconomic Stress and Emotion Regulation in Intimate Partner Violence Survivors’ Posttraumatic Symptomology
Authors: Palm Reed Kathleen , K. Kline Nora , Prichett Brianna
Published: January 2025

The COVID-19 pandemic has resulted in increased rates and severity of intimate partner violence (IPV) and associated posttraumatic stress disorder (PTSD). However, underlying causes of this relationship continue to be understood. The current online survey study examined the relative and compounding impact of COVID-related stressors and emotion regulation difficulties on PTSD symptom severity in a sample of female and male IPV survivors. We replicated findings illustrating a connection between PTSD severity and difficulties with emotion regulation among female IPV survivors and extended these findings to male IPV survivors. However, there was a weaker relationship between emotion dysregulation and PTSD severity among male compared to female IPV survivors. Further, findings revealed a significant association between socioeconomic fears due to COVID (e.g., losing access to food and medication) and PTSD severity. These results provide support for the impact of individuals’ intrapersonal and environmental context on the experience of IPV and PTSD.
Islamization in South Sulawesi and Its Institutionalisation As The State Religion (1605–1611)
Authors: Nasihin Nasihin , Junaeda St. , Tajuddin Fatjri Nur
Published: January 2025

This paper explains how changing Islam, previously the religion of the people of South Sulawesi, became the state religion (Gowa-Tallok Kingdom). Placing the right context in institutionalizing Islam in the Gowa-Tallok Kingdom can explain how Islamization in South Sulawesi took place until 1611. The historical method is used, which focuses on the causal aspects of the events being studied. The causal aspect of events is based on the narrative contained in the sources and references referred to as a marker of library research. This paper explains that the conversion of Islam in South Sulawesi society occurred long before Islam became the state religion. Adaptively, the people of South Sulawesi have been exposed to Islam through a network of Muslim traders and muballigh for 125 years. The people of South Sulawesi had been familiar with the teachings of Islam, subject to external pressures that favored the conversion of local religions to Islam. When Islam was institutionalized as the state religion, it took only 7 (seven) years to convert the people of South Sulawesi to Islam. By 1611, South Sulawesi had been Islamized, except for the mountainous areas in the north.
A Theoretical Framework on Digital Transformation and Knowledge Transfer in Hybrid Work Contexts
Authors: Gentile Teresa Anna Rita
Published: January 2025

The aim of this article is to verify and understand, through the analysis of a theoretical framework, how knowledge transfer (KT) is implemented in organizations that adopt hybrid work contexts as a result of digital transformation (DT). Specifically, we try to relate, through a theoretical and comparative approach, the process of knowledge transfer, carried out according to four models present in the literature, with respect to the main digital tools used in hybrid work (HW). The analysis of the first results shows that in models 1, 2 and 3 of knowledge transfer, the use of software that allows the sharing of documents and the exchange of information are considered to improve the delivery of work performance in the application of hybrid work. On the contrary, the examination of model 4 of knowledge transfer shows the adoption of digital platforms to efficiently share knowledge between employees in hybrid work contexts. In light of this, the originality of this research lies in the ability to provide a theoretical, but well-detailed, study on the possible connections between the four models of knowledge transfer and the digital tools adopted in hybrid work.

An essential indicator of children's health is weight gain and general growth reflecting development, making the understanding of abnormal growth and maturation patterns crucial for early intervention and long-term health outcomes. The Maturity–Development–Nutrition (MDN) matrix method enables the easy identification of intrauterine growth retardation during the newborn period, which can increase the risk of stillbirth and infant mortality. The main purpose was to examine the birth status (length of prenatal development, body length, body weight, nutritional status) of children with classic growth hormone deficiency treated with growth hormone using the MDN matrix method. We examined the birth status of 98 children (67 boys, 31 girls) with isolated growth hormone deficiency who were treated at the North Buda St. John’s Centre Hospital, between 1975 and 2016. We analysed birth status using data on the children’s gestational age, sex, birth length and birth weight. Centile values for birth length and weight were determined using national reference series corresponding to birth year, gestational age and sex. The MDN matrix was used to assess newborn nutritional status and intrauterine growth retardation type. Children with growth hormone deficiency have a prenatal development length that is similar to the Hungarian reference values. However, their birth length and weight were lower than the domestic reference series. According to the MDN matrix method, their nutritional status was similar to that of children born between 2000 and 2012. However, 34.69% of the children were growth-retarded according to their birth developmental status, which was significantly higher than the frequency observed in the children included in the reference series. The results confirm that the MDN method may be appropriate for identifying newborns who would benefit from early investigations to diagnose growth hormone deficiency.

Authors: Conterato Alessandra R. M. , Coelho Daniel B. , Teixeira Luis A.
Published: January 2025

BACKGROUND: Balance deficits in stroke survivors can be attenuated through appropriate training procedures.
AIM: In the current investigation, we aimed to compare gains in dynamic balance between a training protocol employing progressive visual and tactile/proprioceptive constraints against balance training under full sensory information in stroke survivors.
METHOD: Participants were randomly assigned to one of two groups for 12 balance training sessions, three sessions per week. In the constraint group (n=9), training was divided into four blocks of three sessions: full sensory information, visual constraint, tactile/proprioceptive constraint, and the combination of the latter two conditions. In the full sensory information group (n=10), participants trained under full vision supported on a rigid surface. At the end of each training block, evaluations were made through the Berg Balance Scale (BBS) and Timed Up and Go (TUG) tests. Analysis was made through Friedman, Wilcoxon matched-pairs and Mann-Whitney U tests.
RESULTS: Intra and intergroup analyses showed that training under sensory constraint led to higher performance gains than training under full sensory information both in the BBS postural (Δ = 21.20%, p = 0.02) and dynamic (Δ = 18.17%, p = 0.04) tasks. For TUG, analysis of proportional gains indicated significantly greater time reduction in the sensory constraint compared to the full group (Δ = 16.48%, p = 0.03).
CONCLUSION: Balance training under sensory constraint led to higher balance gains than training with availability of full sensory information.

Glucose addiction of cholangiocarcinoma: opportunities for therapeutic development

Published: January 2025

The association between diabetes mellitus, hyperglycemia, and cholangiocarcinoma (CCA) development and progression has been established. One speculation of the effects of high glucose levels promoting CCA progression is via the feeding of substrate to the aerobic glycolysis or so-called Warburg effects in CCA cells. Several glycolytic enzymes and glucose transporters are upregulated in CCA and further activated by high glucose conditions. However, the increased glucose uptake and the increased aggressive phenotypes of CCA under high glucose conditions might not be solely due to this aberrant energy metabolism. High glucose conditions have been proven to be the activator of the other signaling pathways, as well as the precursors for dysregulated glycosylation of oncoproteins in CCA. The higher requirement of glucose and the abundant glucose availability in diabetic conditions then synergize to promote aggressive CCA phenotypes. Additionally, the glucose avidity could also become the Achilles heel of CCA cells, as they could be sensitive to glucose deprivation. The development of therapeutic agents targeting glucose metabolisms or glucose-activated pathways is promising for CCA treatments. This article reviews and discusses the up-to-date research on how high glucose is involved in CCA progression, both via Warburg effects and other mechanisms.

Published: January 2025

HTA introduced by Annett and Duncan is widely recognized for breaking down complex tasks into manageable subtasks, data, and quantitative analysis confirming its effectiveness are limited. By combining the HTA with the NASA Workload Index (NASA-TLX), a subjective workload assessment tool, this study aims to provide a comprehensive assessment of task performance and workload. The project involved assembling a three-jaw chuck with HTA for process definition and subtasks, while NASA-TLX was used for workload determination. Data were collected through questionnaires and observation forms and analyzed to determine the impact of HTA on task performance and workload distribution. The results show that HTA effectively identifies task complexity and bottlenecks, which facilitates task optimization and improves performance. The NASA-TLX integration provides critical insights into individuals' subjective workload and targets areas where task performance and resource allocation can be improved. This study shows that combining HTA and NASA-TLX provides a holistic approach to understanding and improving task performance, ultimately leading to better user experience and productivity.

Published: January 2025

Despite significant advancements, prosthetic hernia repair continues to face unacceptably high complication rates, including postoperative discomfort and chronic pain. These issues often stem from poor biological responses, such as the formation of stiff scar tissue and mesh shrinkage, commonly associated with traditional static meshes and plugs. Recent studies have challenged the conventional approach of reinforcing the groin through fibrotic incorporation of meshes, particularly in light of new evidence on the degenerative origins of many types of abdominal hernias such as groin hernias. In response, the Stenting & Shielding (S&S) Hernia System, a newly designed 3D dynamic device, has been developed for dissection free laparoscopic placement to permanently obliterate hernia defects. Unlike conventional meshes, this device induces a probiotic biological response, promoting viable tissue growth rather than fibrotic plaque formation. In a porcine experimental model, the S&S device demonstrated the development of a great amount of muscle fibers, alongside nervous and vascular structures, within well-perfused connective tissue. Histological analysis of biopsy specimen excised from the experimental animals revealed progressive muscle fiber maturation from early myocyte development in the short term to fully developed muscle bundles in the long term. The enhanced biological response observed with the S&S device suggests a promising shift in hernia repair, potentially reversing the degenerative processes of hernia formation and promoting tissue regeneration. The S&S Hernia System described here can be classified not merely as a conventional hernia implant, but as part of a new category of hernia devices: the dynamic regenerative scaffold.
A New Paradigm in Abdominal Hernioplasty: The Stenting & Shielding Hernia System Activates Tissue Growth Factors and Regenerates the Abdominal Muscle Barrier

Published: January 2025

The current gold standard for abdominal hernia repair involves the use of flat meshes deployed over the hernial defect via open or laparoscopic surgery. However, these conventional methods often lead to complications related to implant fixation, suboptimal biological response, and inadequate defect management. To address these challenges, a novel treatment approach has been developed using the Stenting & Shielding (S&S) Hernia System. This innovative device is laparoscopically introduced into the hernial opening without requiring tissue dissection, and it expands to permanently obliterate the defect without the need for fixation. Unlike the foreign body reaction typically observed with flat meshes, the 3D design of the S&S device exhibits dynamic responsiveness, promoting true tissue regeneration. By moving in harmony with the abdominal wall, the S&S device attracts growth factors that induce the formation and maturation of new muscular, vascular, and nervous structures, effectively restoring the integrity of the abdominal wall compromised by hernia disease. This regenerative capability was demonstrated in an experimental porcine model, where the S&S device was implanted and biopsies were taken at defined postoperative intervals ranging from 4 weeks to 8 months. Immunohistochemical analysis of these biopsies revealed the presence of specific tissue growth factors driving the regenerative processes. The results suggest that the three-dimensional design of the S&S Hernia System enables the device to respond to dynamic mechanical strains, thereby fostering progressive tissue regeneration.
Aging as a Loss of Goal-Directedness: An Evolutionary Simulation
Authors: Pio-Lopez Léo , Hartl Benedikt , Levin Michael
Published: January 2025

Aging is an extensive biological process characterized by morphological and functional alterations in cellular and extracellular components, resulting in a systematic decline in biological functions ultimately leading to death. Although substantial advancements have been made in manipulating lifespan in model organisms like C. elegans and mice through genetic, dietary, and pharmacological means, the fundamental mechanisms driving aging in humans remain elusive and widely debated. In addition, there is no comprehensive computational platform capable of making predictions on aging in multicellular systems and integrating the multiscale competency of lifeforms. We propose an evolutionary hypothesis: aging arises because evolution has prioritized development, only to a limited extent incorporating a regenerative program beyond adulthood. Using a cybernetic tissue model and information dynamics analysis, we find: (1) Absence of Long-Term Morphostasis: Aging emerges naturally after development due to the lack of an evolved regenerative goal, rather than just specific detrimental properties of developmental programs (e.g., antagonistic pleiotropy or hyperfunction); (2) Acceleration Factors vs. Root Cause: Cellular noise, reduced competency, communication failures, and genetic damage all accelerate aging but are not its primary cause; (3) Information Dynamics in Aging: Aging correlates with increased active information storage and transfer entropy, while spatial entropy measures distinguish two dynamics—loss of structure and morphological noise accumulation; (4) Dormant Regenerative Potential: Despite organ loss, spatial information persists in the cybernetic tissue, indicating a memory of lost structures, which can be reactivated for organ restoration through targeted regenerative information; and (5) Optimized Regeneration Strategies: Restoration is most efficient when regenerative information includes differential patterns of affected cells and their neighboring tissue, highlighting strategies for rejuvenation. These findings provide a novel perspective on aging dynamics with significant implications for longevity research and regenerative medicine.
Landscape Ecological Integrity Assessment for Forest Ecosystem Improve Protected Area Management Practices
Authors: Yu Mingquan , Liu Yizhen
Published: January 2025

Understanding ecological integrity of protect area is a central topic for the construction and conservation of these key areas. An ecological integrity framework based on landscape ecology was developed in this research, which include a series of index to monitor and evaluate the status and conditions of the landscape among different functional zone in the Xiangjiangyuan Provincial Nature Reserve (XPNR). The result showed that the XPNR has higher ecological quality, and less anthropogenic influence, the ecosystem of the XPNR was generally well maintained. The important landscape types of the XPNR include evergreen broad-leaved forest (EBLF), mixed evergreen deciduous broad-leaved forest (MEDBLF), deciduous broad-leaved forest (DBLF), etc., which have high authenticity and high conservation value. As the result of evaluation of landscape fragmentation and human interference in the three functional zones showed that the core zone < the buffer zone < the experimental zone, which was good to fit the conservation and management requirements of the XPNR. The landscape fragmentation analysis for the important landscape types in all functional area showed that the experimental area and the buffer area were relatively more severe, the core area was lighter with minimal anthropogenic impacts and the most complete protection. As the sustainability and management goal, we suggested some more effectively policies to continuously improve the ecosystem integrity.

This study investigated the pharmacokinetics of levofloxacin niosomes following a single dose administered intraperitoneally to Sprague Dawley rats, using conventional unentrapped drug as reference. Guided by results of previous studies, an experimental design software (DoE Fusion One) was used to design screening experiments that provided factor combinations and processing variable settings that resulted in an optimized formulation. Optimized niosomes of levofloxacin were prepared, characterized and evaluated in vitro for drug release rate. The well-characterized formulation was used for in vivo study in Sprague Dawley rats in a non-cross over parallel study. One of two groups of rats (n = 6 each) was injected intraperitoneally with conventional levofloxacin and the other with levofloxacin niosomes at 7.5mg/kg/dose. Blood samples were collected at ½, 1, 2, 4, 8, 12, 18, 24, 48 and 72 hours via tail snip. Drug concentrations were determined using a validated high-performance liquid chromatographic (HPLC) method. The plasma concentration versus time data from rats were fed into the Gastroplus software (Simulations Plus, CA) and used to model the pharmacokinetic profiles of the i.p. levofloxacin and its niosomes. The optimized drug-loaded niosomes used for in vivo rat study had a mean size of 368.8 (± 11.0 SE), encapsulation efficiency (EE) of 34.21 %, Zeta potential of -42.10 (± 2.07 SE) and mean polydispersity index (PDI) of 0.316 (± 0.014 SE). Following i.p. injection, levofloxacin release was controlled with less than 80 % released in 6 h and about 90% released in 12 h. Modeling of levofloxacin bio-disposition following i.p. injection in rats with Akaike information criterion (AIC) and Schwarz criterion (SC) indicated that the niosomes formulations are best fitted to one-compartment model while the conventional drug formulation followed two-compartment model. The niosomal formulation appeared to alter the biodistribution of levofloxacin, and concentrated the drug in the vascular compartment with slow, sustained distribution outside of the vascular compartment. Overall, the niosomes formulation showed significant increase in levofloxacin mean residence time (MRT), prolonged its elimination half-life (t1/2) and decrease its volume of distribution (Vd). Encapsulation of levofloxacin in niosomes altered its pharmacokinetic profile. It appears that, by vesicular encapsulation, niosomes altered levofloxacin biodistribution possibly by preventing its binding to plasma protein while correspondingly increasing its residence time in systemic circulation. Thus, by protecting intraperitoneally injected levofloxacin en route into the plasma, niosomes significantly enhance its delivery to, and concentration in, the intravascular compartment with enanced potential for treating intravascular conditions like bacteremia.

This article proposes a game-theoretic model for financing the informatization of education, taking into account aspects of university cybersecurity. The model emphasizes the financial interactions between the players. The relevance of the study is due to the increasing interdependence between the quality of education and the provision of cybersecurity in universities, which requires the optimization of resources to create a secure and innovative educational environment. The novelty of the model lies in the use of a differential game of quality with a bilinear structure, where the financial states of the participants are described by a system of differential equations. In this formulation, the model allows for the determination of preference sets and optimal strategies for players, which has been demonstrated in a computational experiment. The visualization of the preference set for the first player, the cybersecurity center (CSC), demonstrates the applicability of the model for solving practical problems of financing the informatization of the educational process, taking into account the tasks of ensuring its cybersecurity.

The identification and classification of traffic is of great significance for maintaining network security, optimizing network management and providing reliable service quality. These functions not only help prevent malicious activities such as network attacks and illegal intrusions, but also effectively support the reasonable allocation of network resources and improve user experience. However, although the wide application of network traffic encryption technology enhances the security of data transmission, it also makes the content of traffic difficult to be directly analyzed, resulting in the existing identification technology is inefficient in the face of encrypted traffic and difficult to accurately classify. This not only affects the maintenance of network security, but also limits the further improvement of network service quality. Therefore, developing efficient and accurate encryption traffic identification methods has become an urgent problem to be solved. However, the existing work still has three main inherent limitations: (1) The potential relationship between the flow load feature and the sequence feature is ignored in the feature extraction process. (2) To adapt to the characteristics of different protocols to ensure the accuracy and robustness of encrypted traffic identification. (3) Training effective deep learning models requires large amounts of manually labeled data. This study aims to propose a method of encrypted traffic recognition based on CLSTM (a combination of 2-conv CNN and BiLSTM) and Mean Teacher collaborative learning. By detecting the fusion features of traffic load features and sequence features, the accuracy and robustness of encrypted traffic identification are improved, and the dependence of the model on labeled data is reduced. The experimental results show that the proposed CLSTM-MT collaborative learning method not only outperforms the traditional methods in the task of encrypted traffic identification and classification, but also improves the performance of the model by using only a small amount of labeled data when the cost of data labeling is high.

Fullerenes, a unique allotrope of carbon, have captured significant attention in multiple scientific fields. As a non-destructive characterization technique, Raman spectroscopy has proven indispensable for investigating fullerenes and their derivatives, offering detailed insights into their vibrational properties. This review discusses the broad utility of Raman spectroscopy in revealing the structural and physicochemical characteristics of fullerenes—from the iconic C₆₀ molecule to an array of its derivatives—highlighting its capacity to detect functionalization-induced changes in molecular structure and electronic properties, while also assessing environmental influences such as solvent effects and temperature variations. Particular emphasis is placed on advanced Raman-based techniques, including enhanced Raman spectroscopy, surface-enhanced Raman spectroscopy (SERS), and tip-enhanced Raman spectroscopy (TERS), for the characterization of fullerenes and their derivatives. These cutting-edge methods offer high sensitivity and ultra-high spatial resolution, greatly expanding the scope of fullerene research and delivering deeper insights into their structural and functional properties.

This descriptive review summarizes the most recent findings on the induction and distribution of viable non-culturable (VBNC) Listeria monocytogenes in food production conditions and food. The aim was to obtain information on the factors that favor the transition to the VBNC state in L. monocytogenes, its resuscitation capacity, and, according to scientific articles published since 2020, how food contamination by the bacterium in VBNC state can be prevented. The methods used for VBNC L. monocytogenes detection were also reviewed. A few studies reported the presence of VBNC L. monocytogenes in food, in which fresh produce and chicken meat were considered. Different physicochemical stresses such as exposure to disinfectants with diverse actions and essential oils, desiccation, low temperatures, absence of nutrients, high NaCl and iron concentrations, and low pH adjusted with acetic acid were reported to induce the VBNC state in L. monocytogenes. The VBNC forms of L. monocytogenes were able to regain growth and virulence. This could pose a safety risk that cannot be revealed by the standard culture-dependent methods recommended for L. mono-cytogenes detection. Therefore, the presence in food and food production plants of VBNC L. mon-ocytogenes should be prevented by appropriate use of hurdles and cleaning/disinfection proce-dures. The opportunity to harmonize VBNC cell detection methods for regular use in food safety evaluation also emerged.
Origins of Aortic Coarctation: A Vascular Smooth Muscle Compartment Boundary Model

Compartment boundaries divide the embryo into segments with distinct fates and functions. In the vascular system, compartment boundaries organize endothelial cells into arteries, capillaries, and veins that are the fundamental units of a circulatory network. For vascular smooth muscle cells (SMCs) such boundaries produce mosaic patterns of investment based on embryonic origins with important implications for the non-uniform distribution of vascular disease later in life. Morphogenesis of blood vessels requires vascular cell movements within compartments as highly-sensitive responses to changes in fluid flow shear stress and wall strain. These movements underlie remodeling of primitive plexuses, expansion of lumen diameters, regression of unused vessels, and building multilayered artery walls. Although loss of endothelial compartment boundaries can produce arterial-venous malformations, little is known about the consequences of mislocalization or failure to form SMC origin-specific boundaries during vascular development. We propose that the failure to establish a normal compartment boundary between cardiac neural crest-derived SMCs of the 6th pharyngeal arch artery (future ductus arteriosus) and paraxial mesoderm-derived SMCs of the dorsal aorta in mid-gestation embryos leads to aortic coarctation observed at birth. This model raises new questions about the effects of fluid flow dynamics on SMC investment and the formation of SMC compartment borders during pharyngeal arch artery remodeling and vascular development.
