A Research Update on Exendin-4 as a Novel Molecule Against
Parkinson’s Disease
Authors: Singh Niraj Kumar , Singh Ashini , Varshney Mini , Agrawal Ritik
Published: May 2023

Parkinson's disease (PD) is the second most prevalent neurodegenerative
disorder, and its consequences severely influence the quality of a patient’s life and
mobility. PD is characterized by bradykinesias with tremors and/or rigidity.
Pathophysiologically, PD is associated with the gradual degeneration of dopaminergic
neurons in the substantia nigra pars compacta of the midbrain, neuroinflammation,
increased accumulation of the alpha (α)-synuclein, overburden of oxidative stress, and
mitochondrial dysfunction. To date, there are no effective therapies with underlying
shreds of evidence that alters the progression of PD. Exendin-4, a glucagon-like peptide
1 (GLP-1) receptor agonist, has gained attention for its tremendous neuroprotective
potential against numerous neurodegenerative disorders, including PD. Further, several
pieces of research evidence have suggested the beneficial role of Exendin-4 in PD-like
experimental models. The present review article highlights the preclinical and clinical
evidence of the therapeutic benefits of Exendin-4 against PD. Exendin-4 reverses the
PD-like symptoms in experimental animals by dramatically minimizing the loss of
dopaminergic neuronal and accumulation of α-synuclein in the PD-like brain. Further, it
also reduces the mitochondrial toxicity and expression of pro-inflammatory mediators
such as tumor necrosis factor (TNF)-α and interleukin (IL)-1β. These observations
designate that Exendin-4 is a multifactorial compound that could be considered a safe,
effective, and new ingredient for developing clinically useful pharmacotherapy for
managing PD-like manifestations.

Published: May 2023

Objective:

The purpose of this study was to assess the performance of computed tomog-raphy (CT) scan and magnetic resonance imaging (MRI) for detecting sacroiliitis in non-radiographic SpA (nr-SpA).

Methods:

This cross-sectional monocentric double-blind study included 63 patients consulting for symptoms suggestive of SpA between February 2014 and February 2017. Patients with convention-al radiographs showing a confirmed sacroiliitis (grade 3 or 4) were not included. Eligible patients underwent CT and MRI of sacroiliac joints (SIJ). CT and MR images were interpreted by 2 experi-enced musculoskeletal radiologists blinded to clinical and laboratory data. Two professors in rheu-matology blinded to radiologists’ conclusions analyzed clinical data, laboratory tests, HLA typing, X-rays, CT and MRI images, and divided the patients into 2 groups: confirmed nr-SpA or no SpA. This classification was considered the gold standard when analyzing the results.

Results:

46 women and 17 men were included in this study. 47 patients were classified as con-firmed nr-SpA (74.6%) and 16 patients as no SpA (25.4%). Sensitivity, specificity, and positive and negative predictive values of CT and MRI for detecting sacroiliitis were, respectively, estimated at 71.7%, 71.4%, 89.2%, 43.5%, and 51.2%, 100%, 100%, and 40%. CT and MRI findings were found to be statistically associated (p<0.001).

Conclusion:

SIJ MRI is a highly specific method in the detection of sacroiliitis, but with a moderate sensitivity. SIJ CT scan, usually known as the third option after radiography and MRI, has much greater diagnostic utility than it has been documented previously.
Affirming Food Waste Mitigation Practices During Pandemic: A Case Study of Green-grocers in Purwokerto, Indonesia
Authors: Nainggolan Racha , Romadlon Fauzan , Ananda Ridho
Published: May 2023

During the COVID-19 pandemic, people tend to panic buying and hoard food supplies. This can trigger an increase in food waste during the pandemic, especially vegetable food waste. This also happens at the level of traders, especially green-grocer who sell in traditional markets. The behavior of traditional market traders who fail to adapt to food safety standards, poor handling, resulting in the emergence of food waste, especially during the pandemic. This study aims to determine the factors that cause vegetable food waste at the level of green-grocers. The method used is qualitative and quantitative with data collection techniques using questionnaires. The sampling was conducted using random sampling and the gained respondents are 111 green-grocers. Then, Chi-Square test is conducted to test the statistical correlation between green- grocer demographic and their preferences about food waste mitigation. The results show there is a correlation between the preferences of green-grocers related to food waste with their demographics. Furthermore, some traders' activities still cause food waste and some of them also don't know what food waste is and what food safety standards are. The less food safety standards, the greater the potential for food waste generated.

A mischievous young rogue and a dwarf: Reflections on the role of the panakawan in the Age of Prince Diponegoro (1785-1855)
Authors: Carey Peter
Published: May 2023

The late eighteenth and early nineteenth century world in which the young Prince Diponegoro (1785-1855) grew up was a deeply traditional one. In the Yogyakarta court of his grandfather, Sultan Hamengkubuwono II (reigned 1792-1810/1811-12/1826-28), and father, the third sultan (reigned 1812-1814), there were special categories of court servants (abdi-Dalem) who served the ruler and provided his close protection. These included the para Nyai (personal female retainers), in particular the elderly Nyai Keparak, who carried the ruler's betelnut (sirih) box and spittoon (Carey 2008: 366, 403); the prajurit Ã¨stri (pasukan Langenkusumo) or Amazon corps who acted as the personal bodyguards of the ruler and were renowned for their skill on horseback (Carey 2008: 76-77); the polowijo or nonok (royal dwarves, the hydrocephalic and those with other unusual physical deformities) who acted as the court jesters (hansworst) and warders against evil; and the panji or young noblemen who formed part of the ruler's intimate circle much like the bachelor knights of the European medieval courts (Carey 2008: 179-80).

Amongst these intimate court servitors none were important than the panakawan. As intimate assistants of the nobility, they combined many roles: tutor, servant, bodyguard, clown, adviser, masseur, herbalist, interpreter of dreams. Their pithy wit deflated pomposity and re-connected the high-born with the world of the Javanese village. As in the wayang clown-servitor figure of the renowned senior panakawan of the Pandawa brothers Semar they might even be gods in disguise. This mix of the demotic and the divine reflects the paradox at the heart of Javanese culture the seemingly misshapen being the vehicle of ultimate wisdom: Een Gedrocht en toch de Volmaakte Mens (a monster but still a perfect man) as the title of a famous study of the Suluk Gathotloco has it (Akkeren 1951).
Disability Identity: Perspective for Policy Formulation
Authors: Widadsyah Muhammad Azhar
Published: May 2023

Policies regarding people with disabilities (PWDs) are formulated without PWDs perceptive and often rule out disability identity owned by PWDs. Those policies potentially result in further issues regarding PWDs empowerment. This research aims to investigate about factors that shape disability identity and how disability identity could provide a new perspective in policy formulation. Researchers interviewed seven PWDs with different disability conditions to gain their perspective on their perception of disability identity. Furthermore, data were analyzed to form three factors of disability identity, which are structural factors, personal and social interaction factors, also organizational development factors. This research also explains how disability identity could be implemented in public policy formulation through some aspects that could be considered further in policy regarding of disability and PWDs.

External Conditions, Internal Rationality: Spinoza on the Rationality of Seneca’s Suicide
Authors: MacLean-Evans Ian
Published: May 2023

I argue alongside some other scholars that there is a plausible reading of Spinoza’s philosophy of suicide which holds both of the following tenets: first, that suicides occur because of external conditions, and second, that there are at least some suicides which are rational. These two tenets require special attention because they seem to be the source of significant tension. For Spinoza, if one’s cognitions are to be the most adequate, they must be “disposed internally” (E2p29s/G II 114), or determined more from one’s own mental nature than from “fortuitous encounters” with other things (E2p29s/G II 114). It may seem there is a conflict, then, in saying both that there are rational suicides in the Spinozist framework, and that suicides must always be a result of external conditions: it seems a suicide simply cannot be rational if it is the result of external conditions. But this tension, it will be shown, can be dissolved. Once this tension is dealt with, I offer some brief closing arguments. I explain how this reading of Spinoza’s philosophy of suicide can satisfy a call for new suicide research which avoids forms of over-individualism and epistemic injustice, and which encourages us to abolish oppressive conditions that lead to rational suicides.

Published: May 2023

Language is very important in our life, because without language we cannot communicate with each other. In communication, language has an important role because with a language we can express what is on our mind. In this case, learning speech act theory becomes important to overcome this problem. Speech acts are actions that can be done through speech. The purpose of this study was to determine the types of speech acts performed by the main character and to determine the function of the speech acts performed by the main character in Luca's film through the script. speech acts are divided into three acts; locutionary acts, illocutionary acts, and perlocutionary acts. In this study, illocutionary acts are the most important speech acts and are related to what the speaker meant. The illocutionary acts are divided into five illocutionary speech acts; representative, directive, commissive, expressive, and declarative. In this study, the researcher found all illocutionary acts performed by the main character in Film luca through the script. And the illocutionary acts used by the main character in Luca's film through the script, the researchers found 113; 27 representative, 45 directive, 4 commissive, 34 expressive, and 3 declarative. The most common illocutionary act is the directive illocutionary act, which is often done by the main character in Luca's film through the script. In this study, the researcher used a qualitative descriptive method in the form of documents in the form of films and scripts to describe and analyze the speech acts selected in the script, then classify them according to the concept of John R. Searle's illocutionary acts. In this study, the researcher found that Luca performed all illocutionary acts: representative, directive, commissive, expressive, and declarative.Keywords: Speech Acts, Illocutionary Acts, Luca Film Script

In this work we studied the auto-oscillation mode of structures based on magnetic tunnel junctions. During the experiment we studied how different values and orientation of the magnetic field affect the efficiency of the self-generation regime for samples of various shapes. The auto-oscillation mode in samples was observed near the transition from one state of magnetization of the free layer to another. It was found that the maximum value of the power spectral density and its position relative to the frequency axis can be controlled by changing the magnitude and orientation of the external magnetic field.

Nanowires from iron were investigated. Samples in the form of arrays of parallel threads (wires) were obtained by matrix synthesis using track membranes. Matrices with parallel pores of 100 nm were used, and the growth voltage was varied - 0.8 V, 1 V and 1.2 V. Electron microscopic studies of the growth matrix and samples were carried out. The obtained data of Mössbauer spectroscopy and magnetometry correlate well. Thus, a comparison of the results obtained by these methods showed that with an increase in the deposition potential during the synthesis of nanowires, the misorientation angle of the magnetic moments of domains increases. It is also shown that as the deposition potential increases, the coercive force decreases.

Thin Co films on inclined Si(001) substrates were obtained by electron-beam evaporation. It has been established that at angles of incidence of the evaporated material on the substrate of more than 80° (oblique angle deposition), arrays of free-standing Co nanocolumns with a cross section of 25 nm and an aspect ratio (length/transverse size) of at least 15 are formed on the substrate surface. In this case, the magnetic easy axis of the film is oriented along the axis of the nanocolumns, which leads to the appearance of a normal component of the magnetization vector to the film surface. When the substrate rotation is turned on, an array of nanospirals is formed. With a fast rotation of the substrate (30 rpm), the magnetic easy axis approaches the normal to the film surface. At a slow substrate rotation (0.6 pm), an array of nanocoils is formed, imparting pronounced chiral properties to the film.

The influence of the shape parameter (oblateness) of a uniaxial ellipsoidal nanoparticle on the dynamics of its magnetic moment upon magnetization along the symmetry axis and excitation by a weak transverse high-frequency field in the region of parameters where the equilibrium magnetic moment of the nanoparticle and the external static field is noncollinear has been studied. It is shown that as the oblateness increases, the irregularity of the oscillations increases, which at first affects only their amplitude, but then also the time dependence. The intervals of the shape parameter (or frequency), where various nonlinear modes of precession are realized - dynamic bistability, complex spatial attractors and chaos, were revealed using bifurcation diagrams.

To study the dependence of the properties of ternary oxides (Mn,Fe,Ga)2O3 with the bixbyite structure on the composition, the temperature dependences of the magnetization and ac magnetic susceptibility of two single-crystal samples of different compositions obtained using the flux method were analyzed. A detailed study of the structure was carried out using single-crystal X-ray diffraction analysis, and the changes in structural parameters depending on the composition were analyzed. The dc magnetization and ac magnetic susceptibility of Fe1.1Mn0.76Ga0.14O3 and Fe0.65Mn1.1Ga0.26O3 bixbyites have been studied. Despite the qualitatively similar behavior of the magnetic properties, significant differences were also found, despite a small difference in the Mn/Fe/Ga ratio in the samples under study. It is shown that both compounds experience two successive low-temperature magnetic phase transitions from the paramagnetic phase at T = 20–32 K as the temperature is lowered. Calculations of the Mydosh parameter for the detected phase transitions showed different degrees of ordering in the compounds under study.

Published: May 2023

An accurate description of the effect of extreme pressure and temperature on the physical properties of materials is required to understand the structure and composition of the mantle of the Earth and similar planets. One of such materials is enstatite MgSiO3, which causes increased interest in the investigating of its behavior under intense dynamic loads. It is proposed to consider the shock-wave loading of enstatite as a mixture of quartz oxides SiO2 and MgO periclase in an equal stoichiometric ratio based on experimental data in which decomposition of magnesium silicates was observed. Calculations are performed using a thermodynamically equilibrium model that takes into account the phase transitions of the components. Phase transitions of SiO2 and MgO are taken into account when modeling high-energy effects on enstatite. The results are compared with the data obtained on the basis of shock-wave loading experiments, as well as with calculations based on the PREM model performed based on the results of seismic exploration.

Published: May 2023

The effect of standing waves of charge density (Friedel oscillations) generated by an interface of the ‘metallic ytterbium nanofilm  single-crystal silicon substrate’ type on the work function of ytterbium nanolayers has been studied. It is shown that in the range of nanofilm thicknesses from 0 to 8 monatomic layers, the work function has an oscillating character. This feature of the dependence of the work function on the nanofilm thickness is a consequence of the fact that the standing waves change nonmonotonically the power (momentum) of the electric double layer, which exists on the metal surface and affects the work function of the metal. This ultimately determines the oscillating nature of the dependence of the work function on the thickness of the nanofilms.

Development of equitable and environmentally friendly public transit services is a pre-requisite if Indonesian cities were to attain sustainability objectives. Recent advances in transportation technology have introduced Autonomous Tram (AT) as an environmentally conscious option. This article investigates the prospect of implementing AT system using Surakarta as a case study. In doing so, we qualitative observe daily mobile patterns obtained through a primary survey and by considering existing Batik Solo Trans (BST) bus routes. Results indicate locations of road corridors most prominently used, overlapped with the existing bus services, indicating the geographic prospects of where to locate the AT system, The results from this study are expected to be a reference in AT research as a potentially sustainable public transportation service in Indonesia.

Published: May 2023

Traditional buildings are one type of structure that can adapt to a dynamic environment. Some functions of the building’s spaces have been changed to the new requirements, but the building's overall shape has been preserved. The purpose of this study was to examine and determine the differences in perceived thermal comfort values ​​between occupants and visitors inside the building. Using the observation method and analyzing the data through PMV-PPD and correlating with the Adaptive method in the Center for the Built Environment (CBE) Thermal Comfort Tool Website, it shows that there are differences caused by the environmental climate that do not match the PMV standard from ASHRAE. This study also has shown a difference of 18% between the PMV value of visitors to occupants, where there are past factors that influence this difference, and also a difference of 0.58 between the PMV value of Fanger and Sugini theory (comparison between general theory that is often used with the local theory that has been researched), because of Indonesians' heat tolerance. In this study, it was found that there are variables that are not needed in the adaptive method approach of naturally ventilated buildings, namely the humidity in buildings that are in tropical and humid areas. The reason for this is that the effect of moisture on the thermal sensation is insignificant, and it can be neglected.
A Brief Discussion of Contract Formation Judgment
Authors: Wang Weiyuan
Published: May 2023

This article agrees that the parties and the unanimity of intent together constitute the elements of contract formation. In general, it is more appropriate to adopt the doctrine of representation to judge and grasp the unanimity of intent. Whether silence constitutes an expression of intent should be considered in the specific circumstances, whether silence is sufficient to infer the meaning of the parties, such as the existence of prior statements or trade practices. In this paper, we try to sort out the elements of the main rule of contract formation - the rule of offer and promise, in order to clarify the path of judging contract formation.
The Economic Dimension of Education, Educational Inequalities and Their Role in Shaping the Democratic Citizen
Authors: Dimitrakopoulou Anastasia
Published: May 2023

In this paper we will deal with the inequalities in the field of education and the way they affect the democratic society. This is a very important issue, especially in our time, because the problem is becoming more intense due to the accelerated economic competition, globalization and the changes taking place in the social fabric of the state’s due to the migration of large parts of the population worldwide. In modern Democracy (Agamben, 2005) there is a strong criticism, which basically focuses on the fact that the modern state of Representative Democracy does not realize the goals set by the revolutions of the 19th century and his proclamations of equality and liberty. In today’s societies, education is an important parameter in the formation of the citizen, who will then play an active role in the creation of a democratic society, which will be governed by democratic principles and values. Although all citizens and stakeholders recognize the requirement for a democratic education, its realization remains a question. Within this context, the question arises whether and under what conditions today’s students can be the emancipated and critical citizens of the future society.
Sanar al margen

Desde que en 1882 se descubriera el bacilo de la tuberculosis, se desencadena una carrera científica para vencer a una enfermedad que se convirtió durante la primera mitad del siglo xx en la principal causa de mortalidad en España.

Una de las medidas para luchar contra ella fue la puesta en marcha por parte del Patronato Nacional Antituberculoso (PNA) de un ambicioso plan de construcciones que consiguiera crear una completa red de sanatorios donde alojar y atender en las mejores condiciones posibles a los enfermos. Estudios como los de los doctores Bassols o Valenzuela comenzaron a crear las bases documentales para establecer y dar a conocer tanto a médicos como arquitectos los lugares y condiciones más idóneas para construir estos sanatorios.

¿Dónde se construyeron finalmente estos gigantes de la sanidad española? ¿En qué situación se encuentra actualmente este legado arquitectónico y cultural de nuestra historia? Muchas de las piezas hoy heredadas y diseminadas por todo lo ancho del territorio español se encuentran en un alarmante estado de abandono.

Este artículo pretende otorgar justicia a todo el conjunto de la operación de diseño y construcción del PNA sacando a la luz una obra realmente espectacular que recorre toda la geografía española.
Habitar al margen

Es posible reconocer en la trayectoria de Alejandro Herrero Ayllón diferentes marginalidades. Sus circunstancias personales lo llevaron a aislarse de su entorno en diferentes ocasiones. Fue un estudiante que se preocupó por la arquitectura anónima y como arquitecto fue consciente de la responsabilidad social de la arquitectura y en sus proyectos estimulaba la convivencia y vida saludable para los habitantes de las viviendas que proyectaba en la posguerra española. Proyectos que Herrero consideraba prioritarios tal como lo manifiesta en la correspondencia continuada con su amigo Félix Candela, exiliado en México. Partiendo de sus documentos personales este artículo revisa la producción arquitectónica y palabra escrita de Herrero en torno al habitar al margen, rescatando sus propósitos donde las personas eran consideradas prioritarias; tema también enfatizado por Jane Jacobs en la década de 1960 y necesarios en el urbanismo contemporáneo.
El jardín urbano del Parque Biblioteca San Javier de Medellín
Authors: Viccina Linares Humberto
Published: May 2023

La Arquitectura como elemento regenerador y promotor del espacio público. El jardín urbano del Parque Biblioteca San Javier de Medellín es un buen ejemplo que nos permite analizar la manera en que, a partir de un edificio de tipo sociocultural, se puede revitalizar un área de la ciudad, más aún de un ámbito urbano dominado por la fragmentación espacial. En este artículo se analiza cómo se logra el espacio intermedio entre la arquitectura y la ciudad, conformándolo de acuerdo a las características topográficas del lugar y haciendo que el propio edificio brinde puntos de conexión con lo público a través de la fluidez espacial de su área interior en la conexión con sus diversos accesos. Todo contribuye a crear un hito urbano que también aprovecha la cercanía de una estación del metro, conectándolo así con toda la ciudad.
Escribir arquitectura
Authors: Konzevik Gabriel
Published: May 2023

Con motivo de su número 50 el comité editorial de Bitácora Arquitectura convoca a una celebración, y plantea el desafío de “llevar al lenguaje escrito una disciplina que por su naturaleza suele expresarse gráficamente”, en resumen, a “escribir arquitectura”.

Este ensayo apunta algunas notas sobre el sentido y límites del lenguaje hablado y escrito en el desarrollo del proyecto porque su papel es menos evidente que el del dibujo. Abordaré, aquí aquellos textos y relatos que hacen directamente al ejercicio profesional, aquellos que se asientan durante el proceso proyectual, generalmente en bitácoras.
Entre líneas y espacios
Authors: Martinez Laureana
Published: May 2023

El siguiente ensayo es un ejercicio de construcción espacial y literaria que plantea, a través de un recorrido por distintos espacios, personajes y épocas, una forma diferente de aproximarse a la literatura y a la arquitectura desde una perspectiva de género. A partir de dos ejemplos en concreto y a través de un ejercicio de escritura colaborativa, buscaremos dejar —entre líneas y espacios— la importancia de la participación femenina en la arquitectura y en particular de su registro a través de la palabra escrita.
A personagem e a ação na dramaturgia de José Saramago. Uma leitura de A Noite
Authors: Camargo Pirani Luciana de Cassia
Published: May 2023

As obras A Noite (1979), Que farei com este livro?  (1980), A segunda vida de Francisco de Assis (1987), In nomine Dei (1993) e, por fim, Don Giovanni ou o dissoluto absolvido (2005) constituem o conjunto de dramaturgia publicado por José Saramago. Nesses textos ficcionais, as relações entre o eu e o outro promovem a ação, não distante do que acontece na vida. Este trabalho analisa a articulação entre a ação, a criação e o desenvolvimento da personagem dramática saramaguiana em A Noite. O objetivo é identificar se as ações praticadas pelos personagens vão além do motivo e causa última da existência do personagem dramático, se dialogam com princípios de uma ideologia ética que influenciaria, e de que forma, a estética de Saramago. Perante esta hipótese, para além das obras acima referidas, contribuíram para esta análise textos não ficcionais de José Saramago: Discursos de Estocolmo, Cadernos de Lanzarote, Carta de Deveres e Obrigações dos Cidadãos, associados às obras de Patrice Pavis, Edélcio Mostaço, Robert Abirached e Luigi Pirandello. A opção pelo diálogo entre ficção, não ficção e os textos dos referidos teóricos contribuiu para a compreensão das peculiaridades do texto teatral e de seus elementos, em especial, o personagem e a ação; compreender os conceitos de ideologia, ética e estética, bem como identificar a ideologia ética de Saramago e como ela se manifesta na estética do texto dramático por ele produzido. A análise sugere que a transição entre espaços nas obras de José Saramago pode ser entendida como uma estratégia que vai além da realização artística do personagem. O movimento e a ação importam para o exercício da ideologia ética de Saramago: o dever de ter deveres para com o outro, não basta ser personagem, é preciso ser cidadão, é preciso ser personagem-cidadão.

Authors: Tahric Alma , Kolic Haris , Lavic Aida , Latinovic Dado , Pramenkovic Emina
Published: May 2023

To generate oregano essential oil, the leaves and flowering tops of the Origanum vulgare plant go through the process known as steam distillation. This essential oil is known for its antibacterial activity. Bacterial biofilms are microbial communities attached to inert surfaces or tissues and encapsulated in complex matrices. Planktonic bacteria reversibly attach to surfaces, form microcolonies, and generate polymeric matrices around biofilms. Bacteria in biofilms provide bacteria with a safer way to reproduce and survive. This research tests the antibacterial activity and effect on the biofilm formation of Oregano essential oil. The antibacterial activity and effect on biofilm formation were tested against five bacterial strains, including Escherichia coli ATCC 14169, Escherichia coli ATCC 25922, Staphylococcus aureus NCTC 12393, Staphylococcus aureus ATCC 25923, and Staphylococcus aureus ATCC 6538. The concentrations of oil that were used in this research were 100%(v/v), 75%(v/v), 50%(v/v), and 25%(v/v). The best antibacterial effect was achieved against Staphylococcus aureus NCTC 12393 at 25%(v/v) of oil concentration. While performing the experiment, a variety of oregano oil concentrations had significant results for further tests to be performed.

Published: May 2023

This study aimed to evaluate the presence of coliforms in 50 samples (25 ready-to-eat vegetable salads and 25 handlers’ hands) collected randomly from restaurants in Baghdad. The total coliform count in the samples of vegetable salads from Al-Sadria and Hay al-Amel reached 4.78 and 4.32 log cfu/g, respectively, whereas those in the swab samples of handlers’ hands from the same areas reached 3.70 and 3.90 log cfu/g, respectively. The percentages of fecal coliform bacteria in the salad samples from Al-Sadria and Hay al-Amel were 35% and 32%, respectively, whereas those in the hand swabs from the same areas were 41% and 36%, respectively. Two isolates of the serotype Escherichia coli O157:H7 were detected in the study samples from the same areas, where the rates of E. coli and fecal coliform bacteria increased. Considering the virulence of this bacterial serotype and its direct impact on consumer safety, we highly recommend implementing quality programs in ready-to-eat vegetable salad production chains, raising the cultural level and health awareness of restaurant owners and workers preparing these salads, and raising public awareness of the potential health risks of consuming contaminated food products.
