Authors:   Российский государственный университет нефти и газа (НИУ) имени И.М. Губкина, Будзинская Ольга Владимировна
Published: July 2021

В нефтегазовой отрасли полным ходом идут процессы цифровой трансформации, требующие постоянного обновления компетенций персонала. Система подготовки кадров не справляется с задачей обеспечения опережающего образования. Высокотехнологичные отрасли испытывают кадровый голод. Корпоративные университеты более динамичны в своем развитии и способны быстро рефлексировать на внешние изменения. Цель исследования заключается в выявлении элементов корпоративной среды, наличие которых позволяет компаниям обеспечить кадрами стратегические проекты. В настоящее время к наиболее значимым элементам автор относит систему управления знаниями; HR-аналитику на основе предиктивной аналитики и анализа больших данных (Big Data); применение иммерсивных образовательных технологий; обучающее рабочее место и затраты на обучение персонала. На основе балльно-факторного анализа автор разработал методику оценки роли корпоративного университета в кадровом обеспечении стратегических проектов компании. На основе полученных результатов удалось проранжировать зарубежные и российские нефтегазовые компании по их способности обеспечить стратегические проекты персоналом с требуемым набором компетенций.

Interdepartmental interaction in social support of persons without a fixed place of residenc
Authors: Sukhanova Tatyana Vasilievna
Published: July 2021

Persons without a fixed place of residence currently constitute a certain social group, characterized by a constant growing trend, in particular, due to persons released from prison, which increases its social risk, expressed in the potential environment for crimes, social danger, as well as the degradation of an individual as a whole. The activities of state institutions of the social support system for homeless persons are primarily related to the restoration of a person's status in various fields, including in the legal sphere in the form of restoration of lost documents and in the labor sphere — job search. The solution to these problems involves the inclusion in social support of non-governmental organizations that have low requirements for the status of homeless people and assume work on their «territory», which implies the complete absence of any barriers. In this regard, it is necessary to develop intersectoral interaction between the state and the non-profit sector in the system of social support for people without a fixed place of residence.

Un monde plus que jamais enchanté ?

Note de lecture sur la résurgence contemporaine des cultes aux esprits en Thaïlande et au Viêt-nam.

Bénédicte Brac de la Perrière.

Toute une littérature récente consacrée à l'étude du champ du religieux dans les sociétés contemporaines de l'Asie du Sud-Est continentale montre que dans cette région les cultes aux esprits connaissent un renouveau notable. Cette note de lecture, qui s'appuie principalement sur deux ouvrages de cette production — celui de Rosalind Morris, In the Place of the Origins : Modernity and Its Mediums in Northern Thailand et celui de Philip Taylor, Goddess on the Rise : Pilgrimage and Popular Religion in Vietnam — montre que les cultes nouveaux décrits, s'ils émergent des formes de religiosité anciennes liées au culte des esprits, ne sont pas des archaïsmes et constituent en fait un produit de la modernité.
Jardins sacrés d’Emar au Bronze Récent
Authors: Beyer Dominique
Published: July 2021

Rares sont, dans le domaine de l’archéologie de terrain, les occasions de retrouver les vestiges d’un jardin du Proche Orient antique. Si la restitution d’un ensemble aussi prestigieux que celui des jardins suspendus de Babylone pose encore bien des problèmes, à plus forte raison celle d’installations plus modestes, qui ont laissé peu de traces matérielles et encore moins de souvenirs textuels. Les dispositifs de cuvettes retrouvées creusées dans le sol d’une esplanade cultuelle située à l’arrière de deux temples majeurs de l’ancienne Emar, en Syrie du Nord, à la fin du Bronze Récent, apparaissent comme de bien modestes vestiges. Mais, associés aux restes d’un autel, ils révèlent sans doute un exemple de haut lieu de type sémitique, où un jardin temporaire, sorte d ’«orangerie», devait jouer un rôle essentiel lors de certaines cérémonies en l’honneur de divinités de la végétation, telles que Ba'al ou Dagan. Un texte cunéiforme, retrouvé dans l’un des temples de la ville, permet de conforter une telle interprétation. Il évoque en particulier des sacrifices et des rites d’ensemencement en l’honneur de Dagan, «seigneur des semences».
Le lit d’Héra dans l’Héraion d’Argos
Authors: Kauffmann-Samaras Aliki
Published: July 2021

Das Belt der Hera im Héraion von Argos

Im argivischen Heraion, im Pronaos des Tempels, hat Pausanias (II, 17, 3) ein „Bett der Hera“ gesehen, das die Religionsforscher in Zusammenhang mit gewissen Riten zu Ehren der Hochzeitsgöttin gebracht haben. Andere Betten, von verschiedener Größe und aus verschiedenen Materien, waren in Tempeln ausgestellt oder befanden sich ais Beigaben in Gräbern. Noch andere, wie ein Exemplar des Louvre, sind unbekannter Herkunft. Seit mykenischer Zeit sind durch literarische oder archäologische Zeugnisse Mythen und Feste der Hierogamie überall in der griechischen Welt belegt. Die Vasenmalerei dokumentiert die Vorbereitung des Hochzeitsbettes, eine Sitte die in manchen Gegenden Griechenlands heute noch fortgeführt wird.
La dénomination de l’artisan chez Platon et Aristote
Authors: Lévy Edmond
Published: July 2021

Le dèmiourgos platonicien travaille pour autrui en fabriquant quelque chose (ou en fournissant un service) à l’aide d’une technè ; il se distingue ainsi du géorgos, qui est censé, au moins en tant que géorgos, travailler pour lui-même et qui produit de la nourriture.

Si l’on se place au point de vue de la chose produite, le dèmiourgos est avant tout un producteur ou un créateur, d’où les nombreux emplois du mot, qui, chez le philosophe, en vient même à désigner le Créateur.

Aristote emploie encore dèmiourgos pour évoquer la création ou même la génération, mais le mot n’est plus habituel pour désigner l’artisan, qualifié ordinairement de technitès ou de banausos. Si le premier terme est laudatif, il ne désigne que la catégorie supérieure, souvent aisée, des artisans. Au contraire, banausos, terme péjoratif dès l’origine, désigne l’ensemble des artisans.

L’étude du vocabulaire montre ainsi que de Platon, et sans doute Socrate, à Aristote, l’artisan s’est déprécié.

Natur und Landschaft bei Basil und Augustin

Published: July 2021

Der Artikel setzt ein mit einer Skizze der Anschauungen Augustins liber das Reisen und seine Ästhetik, ehe er dessen Begegnung mit Natur und Landschaft nachzeichnet und mit der-jenigen des groBen ôstlichen Theologen und Mônchsvaters Basilius von Caesarea vergleicht. DaB bei Augustin ein besonders problematisches, besonders belastetes Naturverhaltnis vorliege, wird ebenso in Frage gestellt wie, daß wir bei Basilius der „erste(n) in der Tiefe empfundene(n) Schilderung einer Landschaft“ begegnen, „die die abendlandische Welt kennt“ (von Campen-hausen). Augustin und Basilius haben wohl nicht wenig zur Ausbildung einer annâhernd gesunden Naturtheologie und -frömmigkeit beigetragen, wobei sich die Unterschiede zwischen Ost und West, griechischer und lateinischer Patristik (wieder einmal) ais weniger gravierend erweisen, ais vielfach angenommen wird.
L’évergétisme ob honorem en Bétique
Authors: Dardaine Sylvie
Published: July 2021

The evergetism ob honorem in Baetica.

The 31 inscriptions confirm the voluntary character of this type of gifts that is added to the summa honoraria. They show however the peculiarity of this province in the Western part of the Empire : we find far fewer gifts than in the Proconsularis or in Numidia but much more than in the Gallic provinces, even in the Narbonensis, or even in the other provinces of the Iberian peninsula. Almost always the evergetes are seviri or priests : in Baetica the gifts ob honorem were more the achievement than the preparation of a career.

The gifts of priests and magistrates are in general bigger than those of the seviri. It is sometimes possible to catch a glimpse ot the familial strategies whose aim was to monopolize the local government.
Broadband THz Sources from Gases to Liquids
Authors: E Yiwen , Zhang Liangliang , Tcypkin Anton , Kozlov Sergey , Zhang Cunlin , Zhang X.-C.
Published: July 2021

Matters are generally classified within four states: solid, liquid, gas, and plasma. Three of the four states of matter (solid, gas, and plasma) have been used for THz wave generation with short laser pulse excitation for decades, including the recent vigorous development of THz photonics in gases (air plasma). However, the demonstration of THz generation from liquids was conspicuously absent. It is well known that water, the most common liquid, is a strong absorber in the far infrared range. Therefore, liquid water has historically been sworn off as a source for THz radiation. Recently, broadband THz wave generation from a flowing liquid target has been experimentally demonstrated through laser-induced microplasma. The liquid target as the THz source presents unique properties. Specifically, liquids have the comparable material density to that of solids, meaning that laser pulses over a certain area will interact with three orders more molecules than an equivalent cross-section of gases. In contrast with solid targets, the fluidity of liquid allows every laser pulse to interact with a fresh area on the target, meaning that material damage or degradation is not an issue with the high-repetition rate intense laser pulses. These make liquids very promising candidates for the investigation of high-energy-density plasma, as well as the possibility of being the next generation of THz sources.

Authors: Ebrahimzadeh-Attari Vahideh , Panahi Ghodratollah , Hebert James R. , Ostadrahimi Alireza , Saghafi-Asl Maryam , Lotfi-Yaghin Neda , Baradaran Behzad
Published: July 2021

Background: The novel coronavirus (COVID-19) is considered as the most life-threatening pandemic disease during the last decade. The individual nutritional status, though usually ignored in the management of COVID-19, plays a critical role in the immune function and pathogenesis of infection. Accordingly, the present review article aimed to report the effects of nutrients and nutraceuticals on respiratory viral infections including COVID-19, with a focus on their mechanisms of action. Methods: Studies were identified via systematic searches of the databases including PubMed/ MEDLINE, ScienceDirect, Scopus, and Google Scholar from 2000 until April 2020, using keywords. All relevant clinical and experimental studies published in English were included. Results: Protein-energy malnutrition (PEM) is common in severe respiratory infections and should be considered in the management of COVID-19 patients. On the other hand, obesity can be accompanied by decreasing the host immunity. Therefore, increasing physical activity at home and a slight caloric restriction with adequate intake of micronutrients and nutraceuticals are simple aids to boost host immunity and decrease the clinical manifestations of COVID-19. Conclusion: The most important nutrients which can be considered for COVID-19 management are vitamin D, vitamin C, vitamin A, folate, zinc, and probiotics. Their adequacy should be provided through dietary intake or appropriate supplementation. Moreover, adequate intake of some other dietary agents including vitamin E, magnesium, selenium, alpha linolenic acid and phytochemicals are required to maintain the host immunity.

Authors: Aliakbarzadeh Arani Zahra , Zanjari Nasibeh , Delbari Ahmad , Foroughan Mahshid , Ghaedamini Harouni Gholamreza
Published: July 2021

Background: Place attachment is the emotional bond between individuals and environment, which seems to increase wellbeing in old age. The purpose of this study was to explore the concept of place attachment from older adults’ perspective. Methods: In this qualitative study, a total of 14 older adults were purposively included in Aran and Bidgool city, Isfahan, Iran. The data were collected using a semi-structured interview and analyzed applying a directed content analysis approach. Results: As participants reported, place attachment meant intensive love, pride, dependency, and familiarity with the environment. Socio-economic attachment was identified as the most prevalent dimension of place attachment, followed by affective, physical, autobiographical, and religious-cultural attachment. Conclusion: Our findings provided a new understanding of place attachment in the context of Iran. The concept of place attachment was identified with a multidimensional nature from Iranian older adults’ perspective. Such a multidimensionality of place attachment should be considered while planning for age-friendly cities or the operationalization of the subject of aging in place, particularly in the developing societies, like Iran.

Published: July 2021

Background: Physical activity (PA) is a strong contributor to enhancing a healthy lifestyle and preventing numerous chronic diseases. As ethnic minorities engage in low levels of PA, psychosocial and activity-based interventions for sustaining PA are crucial. Methods: The 6-month intervention incorporated culturally tailored educational workshops and weekly PA classes at a community center. Educational workshops were led by six trained community health workers (CHWs). Participants (n=37) completed pre- and post-intervention questionnaires regarding PA related self-efficacy, outcome expectations, social support, enjoyment, self-regulation, goal setting, and overall PA. Results: Following the intervention, study participants exhibited increases in weekly PA levels. Wilcoxon Signed-Rank test revealed higher median scores for Exercise Self-Efficacy Scale (ESES), Identified Regulation, and Intrinsic Motivation. Positive changes were observed for Physical Outcome Expectations, Social Outcome Expectations, Self-Evaluative Outcome Expectations, Physical Activity Enjoyment, Social Support for Exercise Scale – Family, Social Support for Exercise – Friends, and Exercise Goal-Setting. Conclusion: Community-based PA interventions may provide potential benefits to Filipino Americans, an ethnic Asian minority group, in identifying exercise benefits, developing proper exercise goals, increasing motivation, promoting PA behavior, and facilitating long-term PA adherence.
Prevalence of violent advertisements in New York City subways
Authors: Fullwood Dottington , Cameron Carrie , Means Sydney , Anton Stephen , Stickley Zachary L. , Hale Randal , Wilkie Diana J.
Published: July 2021

Background: Media advertisements displaying aggression and violence in public transit spaces represent a public health concern. The high visibility of ads likely contributes to increased levels of aggression among New York City (NYC) youths traveling across boroughs. Given the importance of the physical, psychological and social environment in shaping the lives of youth, additional attention is warranted regarding how media advertisements are promoted within public transit spaces across America. The aim of this study was to document quantity and placement of advertisements illustrating aggressive and violent content throughout the NYC public transit subway system. Methods: This cross-sectional study was conducted over a five-day period in June 2017. Direct observation was used to document all advertisements within every NYC Metropolitan Transit Authority (MTA) subway station (N = 472) in four NYC boroughs: Bronx, Brooklyn, Manhattan and Queens. Static media advertisements with/without aggressive and violent content displayed on subway platform wall panels above and underground were counted, photographed and described with a mobile app. Results: Aggressive and violent ads in the MTA were pervasive. Subway platforms displayed advertising consisting of guns, individuals fighting and attacking, and words with aggressive language. Conclusion: Public transit spaces provide unregulated visual and verbal messages without citizen participation. Subway stations in NYC and across the country prohibition stance could be a model for violent content reduction. Given the pervasive and tragic effects of aggression and violence on youth and adults, transit agencies could inundate passengers with positive advertising content. Dialogue between citizens and transit agencies to remove noxious messages from public transit spaces warrants the same discussion given to banning alcohol advertisements.

Published: July 2021

Background. This systematic review aimed to determine the effectiveness and outcomes of immediate loading methods for short dental implants. Methods. The authors independently conducted an electronic search in the PubMed, Embase, EBSCO, ProQuest, and Cochrane databases for relevant articles published until November 15, 2020. The references of the included studies were assessed, and a manual search was conducted in Google Scholar and PubMed to find additional relevant studies. Results. Finally, three studies were selected and included in this systematic review. Significant heterogeneity existed in the design of the included studies, and due to the low number of the included studies, the authors could not perform a meta-analysis. The studies showed that the survival rate of immediate-loaded short implants is comparable to conventional loading methods. However, more marginal bone loss is expected. Overall, the immediate loading of short dental implants might be clinically successful. Conclusion. Based on the results, immediate loading protocols might be safely used for short implants. However, caution should be exercised in interpreting these results. Future welldesigned randomized clinical trials with more participants and study power are necessary to support the findings of this systematic review.

Authors: Ateeq Hira , Zia Afaf , Husain Qayyum , Bey Afshan
Published: July 2021

Background. This cross-sectional study investigated the bone mineral density (BMD) in type 2 diabetes mellitus (T2DM) subjects with or without chronic periodontitis (CP). Methods. A total of 120 subjects aged 35‒55, divided equally into four groups: i) T2DM with CP, ii) T2DM without CP, iii) CP alone, and iv) healthy patients, were included in this study. Clinical parameters like plaque index (PI), gingival index (GI), and probing pocket depth (PPD) were recorded. All the participants were evaluated for blood sugar levels using glycated hemoglobin (HbA1c) and BMD by Hologic dual-energy x-ray absorptiometry (DEXA) scan. The association of BMD with clinical periodontal parameters and HbA1c in all groups was investigated using linear correlation analysis (r). Results. The mean value of BMD (0.9020±0.0952 g/cm2) was lower in subjects with both T2DM and CP compared to T2DM and CP alone. BMD was weakly correlated with all the clinical periodontal parameters; a positive correlation was observed between BMD and GI in the T2DM and CP group (r=0.405, P=0.026) and the CP group (r=0.324, P=0.081). A weak positive correlation was observed in BMD and HbA1c in the T2DM group (r=0.261, P=0.13), T2DM and CP group (r=0.007, P=0.970), with a negative correlation to HbA1c in the CP group (r= -0.134, P=0.479). Conclusions: Diabetes mellitus impacts clinical periodontal status and bone mass, and the effect is accentuated when chronic periodontitis is present. Based on the present study, BMD is associated with T2DM and CP, but a weak correlation was observed between BMD and HbA1c and clinical periodontal parameters.

Authors: Ratchagame Vicknesh , Prabakaran Vetriselvi
Published: July 2021

Abstract Introduction: Venous access in neonates is a basic yet critical component in neonatal intensive care unit (NICU). Central venous access and peripheral intravenous access are mostly preferred for delivering medications and intravenous fluids. This study aimed to compare the risks involved in central venous catheters and peripheral intravenous lines among term neonates. Methods: A prospective cohort study was carried out among 78 term neonates in the NICU of a tertiary care center in puducherry in India. Convenience sampling technique was used to enroll the neonates who met the inclusion criteria. Data pertaining to demographic and clinical characteristics, cannulation details, indwelling time, and incidence of thrombosis, phlebitis, occlusion, extravasation, and sepsis were collected by direct observation and from case record. Data were analyzed using SPSS software version 21. To analyze the data, descriptive statistics including frequency, percentage, mean, and standard deviation and inferential statistics including Fisher’s exact test were utilized. Results: Our findings indicated that the risks of thrombosis and phlebitis were significantly higher in peripheral intravenous line group than the central venous group. There was no statistically significant association between the risks and demographic and clinical characteristics in both of the venous access system. Conclusion: According to our results, the use of central venous catheter among neonates showed lower risks than peripheral intravenous lines. Hence, using central venous catheter may be given priority in the NICUs.

Published: July 2021

Abstract Introduction: Self-care programs can raise health in patients with Multiple Sclerosis (MS). This study aimed to identify the self-care behaviors and determinants in patients with MS according to the Health Belief Model (HBM). Methods: In this cross-sectional study, we included 280 MS patients through convenience sampling method. The collection tool was a self-administered questionnaire based on HBM. The participants were the members of MS society in Kerman, Iran. The data were analyzed using descriptive statistics, path analysis, and multivariable linear regression in SPSS software Version 22. Results: The mean (SD) score for self-care practices was 2.86 (0.64), and medication adherence was the most conducted practice. The perceived benefits and cues to action exerted positive influence on self-care practices. The most frequent symptoms experienced by the participants were fatigue (82.5%), visual impairment (76.4%), headaches (72.1%), and muscle weakness (71.4%). The most important cues to action for self-care behavior were the physician (77%), media (52%), and other MS patients (32%). Conclusion: The quality of life (QOL) of MS patients is heavily influenced by self-care behaviors. In this study, only about half of the patients accomplished self-care behaviors, which seems to be insufficient. Since the perceived benefits and cues to action are the main predictors of self-care practices, intervention based on these two constructs can be utilized to promote self-care programs and QOL in MS patients. Health-care providers should pay more attention to these factors for promoting self-care behaviors.

Published: July 2021

ABSTRACT Introduction: More than half of women in Iran experience intimate partner violence (IPV). This study aimed to explore IPV in women with breast cancer (BC) in Ardabil, Iran. Moreover, the predictors of violence and women’s reactions against violence were examined. Methods: Using a convenient sampling method, the current cross-sectional study was performed on 211 women with BC in northwest of Iran. To collect data, a questionnaire consisting of demographic characteristics and items based on PRECEDE-PROCEED model and women's reaction to violence was used. Data were analyzed using SPSS Ver. 20 and descriptive and inferential statistics. Results: In this study, 190 (90%) subjects reported that they had experienced IPV in the preceding year. Only 27(12.8%) women were familiar with all forms of violence. Moreover, 141 (66.8%) and 160 (75.8%) women had no access to counseling centers and life skill training courses, respectively. Women mostly had adopted emotion-oriented coping strategies when facing IPV. The results of multivariate regression analysis indicated that enabling factors and knowledge were predictors of problem-oriented coping strategies in women. Conclusion: Empowered women, for the most part, were better educated and had more access to social resources than others. Therefore, empowering women can help reduce the amount of violence they might have to encounter. It is essential that supporting and empowering centers for women be established in the society and efficient laws be enacted to fight IPV.
Efficacy of Transparent vs. Pressure Dressing in Prevention of Post-Cardiac Catheterization Pain, Discomfort and Hematoma: A Systematic Review and Meta-analysis of RCTs
Authors: Sharma Suresh K , Thakur Kalpana , Mudgal Shiv K , Kumar Barun
Published: July 2021

ABSTRACT Introduction: There is lack consensus on superiority of transparent vs. pressure dressing for prevention of post-cardiac catheterization pain, discomfort and hematoma. Therefore, we conducted this systematic review and meta-analysis of available RCTs on this subject. Methods: We performed a systematic search of RCTs published between in 2000-2019 in English language using databases including PubMed Medline, EMBASE, CINAHL, Cochrane Library, ERMED Journals, Clinical trials database, DELNET, Google Scholar and Discovery Search. Studies conducted on adult patients with femoral dressing after cardiac catheterization measuring pain, discomfort, hematoma as intended outcomes have been included. Data extraction, critical appraisal, assessment of risk bias was done and decisions on quality were made on mutual consensus. Mantel-Haenszel (MH) and odds ratio for dichotomous variables was calculated by Review Manager 5.3 software. Results: Out of all identified studies, only 5 studies comprising 664 patients fulfilled the inclusion criteria and met the quality assessment. Incidence of discomfort (25, 333) were significantly less in transparent dressing group as compared to pressure dressing group (149, 331); odds ratio 0.10, 95% confidence interval [CI] 0.06-0.15; I2 = 0%, P= 0.00. Four studies reported significantly lower number of pain cases in transparent dressing (17, 203) as compared to pressure dressing (57, 201); odds ratio 0.13, 95% confidence interval [CI] 0.03-0.59; I2 = 47%, P= 0.01). However, incidence of hematoma did not reveal any significant difference between two groups. Conclusion: Transparent dressing is a better option in patients with femoral/groin dressing after cardiac catheterization as it is more effective in prevention of pain and discomfort.

Flail chest is a life-threatening clinical entity which can be complicated by respiratory insufficiency. Paradoxical motion of a part of chest wall is the basic cause to put the blame on. Consequently, stabilization of the chest wall is occasionally of paramount importance to achieve early extubation in a patient with post-trauma respiratory insufficiency. Hereby, a simple, low cost, harmless and effective approach of external stabilization is presented.

Introduction: According to the statistics, vascular injury occurs during the onset of diabetic changes after the production of several byproducts. Many authorities have focused to find an alternative therapy for diabetic patients. In this study, we investigated the therapeutic effects of natural polyphenol like resveratrol on human endothelial cells exposed to malondialdehyde for 48 hours. Methods: Human Umbilical Vein Endothelial Cells were randomly classified into four groups;control, malondialdehyde (2.5 mM), resveratrol (100 μM), and cells received the combined regime for 48 hours. Cell viability was determined by 3-(4, 5-dimethyl thiazol-2-yl) 2, 5-diphenyl-tetrazoliumbromide (MTT) assay. Griess reaction was performed to measure the content of Nitric oxide (NO).Apoptosis was studied by using real-time polymerase chain reaction (RT-PCR) and western blotting assays. Levels of receptor tyrosine kinases like VEGFR-1, -2, Tie-1, and -2 were analyzed by enzyme-linked immunosorbent assay(ELISA). The affinity of resveratrol and malondialdehyde to serum albumin was measured by Surface Plasmon Resonance Assay. Any changes in chromatin remodeling were detected by PCR array analysis. Results: Resveratrol reduced cytotoxicity and NO content inside cells induced by malondialdehyde(MDA) (P < 0.05). Endothelial cell apoptosis was decreased by the reduction of pro-apoptotic factor Bax and increase of Bcl-2 following the incubation with resveratrol (P < 0.05). MDA-induced receptor tyrosine kinases increase was inhibited by resveratrol and reached near-to-normal levels (P < 0.05).Surface Plasmon Resonance revealed a higher affinity of resveratrol to albumin compared to the malondialdehyde-albumin complex. Polymerase chain reaction (PCR) array revealed the potency of resveratrol in chromatin remodeling following the treatment with malondialdehyde (P < 0.05). Conclusion: Based on our findings, resveratrol has the potential to decrease diabetic vascular injury induced by lipid byproducts such as MDA.

Manifestations caused by coronavirus family have presented it in many ways during the previous years. The aim of this systematic review was to gather all possible cardiovascular manifestations of the coronavirus family in the literature. Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched PubMed, Scopus, Web of Science, Cochrane and ProQuest which were updated on May 1, 2020 for the last time. Regarding to the novelty and speed of publications on COVID-19, we searched Google Scholar and also references of included studies and review articles in the systematic search results were searched manually. The searched keywords were the combination of the following MeSH terms: "COVID-19", "SARS", "MERS" and "cardiovascular presentation". The systematic review was registered with ID CRD42020180736 in International Prospective Register of Systematic Reviews (PROSPERO). After screening, 28 original articles and ten case studies (five case reports and five case series) were included. Most of the studies were focused on COVID-19 (20 original articles and four case studies) while the only studies about Middle East Respiratory Syndrome (MERS) were a case report and a case series. Almost all the cardiovascular presentations and complications including acute cardiac injury, arrhythmias and the thrombotic complications were more prevalent in COVID-19 than severe acute respiratory syndrome (SARS) and MERS. The cardiac injury was the most common cardiovascular presentation and complication in COVID-19 whereas thrombotic complications were commonly reported in SARS. The cardiac injury was the predictor of disease severity and mortality in both COVID-19 and SARS.Coronavirus 2019 may present with cardiovascular manifestations and complications in signs and symptoms, laboratory data and other paraclinical findings. Also, cardiovascular complications in the course of COVID-19 may result in worse outcomes.

Background. This study aimed to evaluate the effects of repeated sterilization cycles on the surface alterations of various nickel-titanium instruments, including ProTaper Next (PTN), TF Adaptive (TFA), HyFlex CM (HCM), and 2Shape (2S). Methods. Twenty-four new NiTi files of four different alloys were selected. The instruments in each group were divided into two equal groups, as follows: control and sterilization. The first group was chosen as the control without applying any sterilization procedure, while in group 2, five cycles of sterilization procedures were applied. The surface topographies were evaluated using scanning electron microscope (SEM) and atomic force microscope (AFM). The root mean square (RMS) and maximum height (MH) values and three-dimensional images were recorded. The data were analyzed with the Shapiro-Wilk test, one-way ANOVA, and post hoc Tukey tests. The statistical significance level was set at P≤0.05. Results. Before the experiment, HCM demonstrated the highest RMS value, and 2S showed the lowest. After the procedures, the RMS and MH values deteriorated on the surface of PTX, TFA, and 2S (P<0.001). The HCM was not affected by sterilization processes (P>0.05). Conclusion. The initial irregularity on the surface did not affect the rate of alteration. The HCM files demonstrated superior surface properties after several cycles of sterilization. The PTN, TFA, and 2S presented similar surface responses after five cycles of autoclave sterilization.

Background. The potent anti-inflammatory and immunosuppressive properties of glucocorticoids (GCs) might influence the progression of some disorders, such as periodontitis. Hence, this study aimed to investigate the influence of dexamethasone (DEX) on the alveolar bone loss (ABL) of healthy and periodontally compromised molars in rats. Methods. Thirty male rats were randomly assigned to two groups: physiological saline solution (PSS) and DEX. The animals received subcutaneous injections of either 0.5 mL of PSS) (group PSS) or 2 mg/kg of DEX (group DEX) from one day before experimental periodontitis (EP) induction until euthanasia. EP was induced through ligature placement around the mandibular lower first molars at day 0. Contralateral molars remained unligated. Ten animals per period were euthanized on days 3, 7, and 14. Morphometric analysis was performed to access the ABL. Data were statistically analyzed with ANOVA followed by post hoc Tukey tests (P≤0.05). Results. Higher ABL was observed in both groups on days 7 and 14 than on day 3 (P≤0.05). Concerning periodontitis, higher ABL was observed in group DEX on days 3, 7, and 14 days than group PSS at the same time intervals (P≤0.05). Also, even in the contralateral unligated molars, group DEX exhibited higher ABL on days 3, 7, and 14 days than group PSS at the same time intervals (P≤0.05). Conclusions. Collectively, it can be concluded that DEX aggravates EP and induces spontaneous ABL in the healthy periodontium.

Background. Maxillary bone atrophy with a considerable amount of pneumatization and anterior expansion of the maxillary sinus might be a situation limiting oral rehabilitation with osseointegrated implants. Therefore, the present study aimed to biomechanically evaluate two rehabilitation techniques for maxillary bone atrophy: all-on-four and long trans-sinus implants. Methods. Two three-dimensional models consisting of atrophic maxilla with four implants were simulated. In the M1 model, two axially inserted anterior implants and two tilted implants, 15 mm in length, placed tangential to the maxillary sinus’s anterior wall were used. In the M2 model, two axially inserted anterior implants and two trans-sinus tilted implants, 24 mm in length, were used. For the finite element analysis (FEA), an axial load of 100 N was applied on the entire extension of the prosthesis, simulating a rehabilitation with immediate loading. The peri-implant bone and the infrastructure were analyzed according to the Mohr-Coulomb and Rankine criteria, respectively. Results. The results were similar when the stresses on peri-implant bone were compared: 0.139 and 0.149 for models 1 and 2, respectively. The tension values were lower in the model with trans-sinus implants (27.99 MPa). Conclusion. It was concluded that the two techniques exhibited similar biomechanical behavior, suggesting that the use of long trans-sinus implants could be a new option for atrophic maxilla rehabilitation.

Published: July 2021

Background. Regenerative endodontic treatment (RET) is a clinically advanced procedure for necrotic immature teeth. However, root canal walls of these teeth are brittle especially in the cervical region and need reinforcement. This in vitro study is conducted to evaluate the effect of intra-orifice barrier materials on the fracture resistance of immature teeth treated with regenerative procedure. Methods. Forty-eight maxillary central incisors were used. Twelve intact teeth were selected for the control group. Remained teeth were prepared using peeso drills to simulate immature teeth and assigned into three groups according to the intra-orifice barrier material placed over MTA (n=12); Composite resin (CR), ProRoot MTA and Resin-modified glass ionomer cement (RMGIC). Fracture strength test was applied using a universal testing machine. One-way ANOVA and Tukey post hoc tests were used at P=0.05. Results. A significant difference was obtained among groups (P<0.05). MTA showed the lowest fracture resistance (P<0.05). However, no significant difference was found among RMGIC, CR, and control groups (P>0.05). Conclusion. Intra-orifice restorative materials have reinforcement affect in immature teeth treated with regenerative endodontic procedure. RMGIC or CR can be regarded as a viable choice to reduce the occurrence of cervical root fracture of immature teeth treated with a regenerative therapy.
