Adsorption and inhibition effect of 2,4-diamino-6-hydroxypyrimidine for mild steel corrosion in HCl medium: experimental and theoretical investigation
(SPRINGER HEIDELBERG, 2019) Yildiz, Resit; 09.03. Department of Nutrition and Dietetics/ Beslenme ve Diyetetik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
2,4-Diamino-6-hydroxypyrimidine (2D6H) was examined as corrosion inhibitor of mild steel (MS) in 0.1M HCl using potentiodynamic measurements, linear polarization resistance (LPR), scanning electron microscopy, electrochemical experiments, and quantum chemical calculations. All measurements show that the corrosion inhibition effectiveness is forthright compared to the concentration of 2D6H ranging from 0.5 to 10.0mM. Adsorption of 2D6H on the MS surface in the presence of HCl is determined to obey Langmuir adsorption isotherm. The electronic features elucidated by quantum chemical calculations were associated with the experimental inhibition productivities. The mechanism of inhibition was revealed by E-pzc measurements.

(ELSEVIER, 2023) Güzel, Tuncay; Aktan, Adem; Kılıç, Raif; Günlü, Serhat; Arslan, Bayram; Arpa, Abdulkadir; Güzel, Hamdullah; Tatlı, İsmail; Aydın, Saadet; Suzan, Veysel; Demir, Muhammed; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Background In this study, we investigated whether there is a higher incidence of cardiac implantable electronic devices (CIED) procedures related complications in older (≥75 years) than in younger (<75 years) patients. Methods This retrospective cohort study enrolled patients who had undergone CIED procedures (de novo implantation, system upgrade, generator substitution, pocket revision or lead replacement) at two heart centers in Turkey between January 2011 and May 2023. The primary composite endpoint included clinically signifcant hematoma (CSH), pericardial efusion or tamponade, pneumothorax, and infection related to the device system. Secondary outcomes included each component of the composite end point. Results The overall sample included 1923 patients (1419<75 years and 504 aged≥75 years). There was no diference between the groups in terms of cumulative events defned as primary outcome (3.5% vs. 4.4%, p=0.393). Infection related to device system was signifcantly higher in the≥75 age group (1.8% vs. 3.4%, p=0.034). There was no signifcant diference between the groups in terms of clinically signifcant hematoma and pneumothorax (0.7% vs. 0.4%, p=0.451, 1.4% vs. 1.0%, p=0.477, respectively). In multivariate model analysis, no association was found between age≥75 years and infection related to the device system. Conclusion Infection rates were relatively higher in the patient group aged≥75 years. This patient group should be evaluated more carefully in terms of infection development before and after the procedure.

An analysis of age-standardized suicide rates in Muslim-majority countries in 2000-2019
(BMC Public Health, 2022) Zeyrek-Rios, Emek Yüce; Bob Lew; Lester, David; Kõlves, Kairi; Yip, Paul S. F.; Ibrahim, Norhayati; 02.10. Department of Psychology / Psikoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Background: This study examines the 20-year trend of suicide in 46 Muslim-majority countries throughout the world and compares their suicide rates and trends with the global average. Ecological-level associations between the proportion of the Muslim population, the age-standardized suicide rates, male-to-female suicide rate ratio, and the Human Development Index (HDI) in 2019 were examined. Methods: Age-standardized suicide rates were extracted from the WHO Global Health Estimates database for the period between 2000 and 2019. The rates in each country were compared with the age-standardized global average during the past 20 years. The countries were further grouped according to their regions/sub-regions to calculate the regional and sub-regional weighted age-standardized suicide rates involving Muslim-majority countries. Correlation analyses were conducted between the proportion of Muslims, age-standardized suicide rate, male: female suicide rate ratio, and the HDI in all countries. Joinpoint regression was used to analyze the age-standardized suicide rates in 2000-2019. Results: The 46 countries retained for analysis included an estimated 1.39 billion Muslims from a total worldwide Muslim population of 1.57 billion. Of these countries, eleven (23.9%) had an age-standardized suicide rate above the global average in 2019. In terms of regional/sub-regional suicide rates, Muslim-majority countries in the Sub-Saharan region recorded the highest weighted average age-standardized suicide rate of 10.02/100,000 population, and Southeastern Asia recorded the lowest rate (2.58/100,000 population). There were significant correlations between the Muslim population proportion and male-to-female rate ratios (r=-0.324, p=0.028), HDI index and age-standardized suicide rates (r=-0.506, p<0.001), and HDI index and male-to-female rate ratios (r=0.503, p<0.001) in 2019. Joinpoint analysis revealed that seven Muslim-majority countries (15.2%) recorded an increase in the average annual percentage change regarding age-standardized suicide rates during 2000-2019. Conclusions: Most Muslim-majority countries had lower age-standardized suicide rates than the global average, which might reflect religious belief and practice or due to Muslim laws in their judicial and social structure which may lead to underreporting. This finding needs further in-depth country and region-specific study with regard to its implication for public policy.

Animals and pastoral groups in the mountainous Ömerli district of Southeast Anatolia
(Taylor and Francis Ltd., 2020) Sıddıq, Abu Bakar; Şanlı, Süleyman; 02.01. Department of Anthropology / Antropoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Southeast Anatolia has been an ideal place for pastoralism since the Neolithic period. However, there is a lack of information on human–animal relationships from both archaeological settlements and contemporary societies in the region. Through ethnographic fieldwork and exploratory case studies in the mountainous Ömerli district, we explored the dependency and complex relationships between pastoral groups and various animal species in Southeast Anatolia. The case studies revealed affectionate and emotional bonds between shepherds and some individuals of domestic herds, similar to pet–human relationships in urban societies. Shepherds gave human names to certain animals; sometimes these were the names of their close friends or the names of their own children. Grief and prolonged grief was also common among Ömerli shepherds following the loss, death, or sale of these emotionally bonded animals. It was further observed that a single species (domestic or wild) often had complex and multi-purpose relationships with shepherd groups. While tortoises and hares, for instance, were used as sources of meat, the bone, blood, intestine, skin, and shell of these species were often used in traditional medicine. Although pastoral groups are completely dependent on domestic herds for their basic subsistence, Ömerli shepherds were observed to be regular hunters. It appears that the economic benefits were not the only promoters for pastoral subsistence in the study area; compassion and emotional affection for particular animals also reinforced enthusiasm for the practice. Therefore, it can be argued that the data obtained from pastoral villages in the mountainous Ömerli district help us understand interactions and relationships between humans and nonhuman animals in pastoral societies of Southeast Anatolia.

Chronic Maternal Tobacco Smoke Exposure and/or Alpha-Lipoic Acid Treatment Causes Long-Term Deterioration of Testis and Sexual Behavior in Adult Male Rats
(Elsevier, 2020) Yardimc, Ahmet; Ramazan Fazil Akkoc, Ahmet Tektemur, Nazife Ulker, Nalan Kaya Tektemur, Elif Erdem Güzel, Sinan Canpolat, Ibrahim Enver Ozan; 09.02. Department of Midwifery/ Ebelik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Background: Tobacco use during pregnancy is known to have several negative effects on the offspring's reproductive health in the long term. The use of alpha-lipoic acid (ALA) as a dietary supplement during pregnancy has increased greatly in recent years and has been known to have positive effects on various pregnancy outcomes including miscarriage, diabetic embryopathy, preterm delivery, and congenital malformations. Aim: To evaluate the effects of tobacco smoke exposure (TSE) on sexual behavior, reproductive parameters, and testicles in adult male rats and to reveal the possible role of ALA administration on these parameters. Methods: Pregnant rats (n = 7 per group) were treated with tobacco smoke (TS), ALA (20 mg/kg), and TS + ALA for a total of 11 weeks. The following parameters were compared with 8 control rats: puberty parameters, sexual behavior; levels of serum gonadotropins and testosterone, total antioxidant status, and total oxidant status; the expression of the apoptotic protease-activating factor-1 and caspase 9 mRNA levels in the testis; and assessment of immunohistochemistry and terminal deoxynucleotidyl transferase dUTP nick end labeling assay of testis. Main Outcome Measure: Sexual behavior, changes in puberty parameters, and hormonal and genetic alterations were the outcomes analyzed in this study. Results: Maternal TSE caused a significant decrease in the number of intromissions compared to the control group. Similarly, ALA decreased erectile function in sexual behavior by decreasing the number of intromissions and intromission ratio in the ALA group compared to the control group. In addition, TSE and ALA treatment caused an impairment of some consummatory sexual behaviors. Also, in parallel with this inhibitory effect, the age of pubertal onset was significantly delayed in the TS + ALA group compared to other groups. Also, histopathological changes in testicular tissue, oxidative stress markers, apoptotic index, and mRNA levels of apoptosis-related genes increased in all treatment groups. Clinical Implications: The use of ALA and/or tobacco products during pregnancy may adversely affect the reproductive health of male newborns in the long term. Strengths & Limitations: To the best of our knowledge, this study is the first to show the effects of maternal ALA treatment and/or TSE on the sexual behavior and reproductive parameters in male rats; however, the study is based on an animal model, and the present findings partially reflect the characteristics of human sexual behavior. Conclusion: Maternal TSE and/or ALA treatment may impair sexual behavior in adulthood in male rats because of testicular damage caused by oxidative stress during gonadal development.

Delayed educational services during Covid-19 and their relationships with the mental health of individuals with disabilities
(Wiley Online Library, 2021) Sakız, Halis; 02.04. Department of Educational Sciences / Eğitim Bilimleri Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
During the coronavirus disease 2019 (Covid-19) pandemic, individuals with disabilities (IWD), like many others, have not been able to benefit effectively from educational and school-based mental health services, which are vital to achieving mental good health. This study aimed to collect views of IWD about how their mental health was affected by the school closure during Covid-19. Thirty-one IWD were interviewed and data were analyzed thematically. Findings indicated that the educational delay, combined with the pressure of the preventive measures against Covid-19 was associated with (i) difficulties in emotional well-being, structured routines, learning, and socialization, (ii) enhanced feelings of isolation and pain, and (iii) negative perceptions of academic-self-efficacy and therapy-related outcomes. The findings of the study highlight the importance of urgent short-term and long-term measures to provide safe and individually oriented educational services to compensate for the consequences of the pandemic.

(Clinical Psychopharmacology and Neuroscience, 2021) Güngör, Meltem; Ergul Belge Kurutas, Erkan Oner, Velid Unsal, Hatice Altun, Ali Erdinc Yalin, Serap Yalin, Ozlem Bozkus, Nilfer Sahin; 09.03. Department of Nutrition and Dietetics/ Beslenme ve Diyetetik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Objective: Attention deficit hyperactivity disorder (ADHD) is a heterogeneous, highly heritable, a common childhood neurobehavioural disorder resulting from complex gene-gene and gene-environment interactions. The erythropoietin (Epo)/erythropoietin receptors (EpoR) system turned out to have additional important functions in nonhematopoietic tissue. In this study, we aimed to investigate the levels of Epo and and EpoR, and also their diagnostic values in children with ADHD. Methods: A total of 70 children were included in the study, 35 drug-naive patients with ADHD (age: 6−12 years; male/female: 20/15) and 35 healthy controls (age: 6−12 years; male/female: 22/13). Serum Epo and EpoR levels was determined using a commercial sandwich enzyme-linked immunosorbent assay kit. Results: The results indicated that the levels of Epo decreased in patients with ADHD compared to control (p < 0.05). On the other hand, EpoR levels increased in these patients (p < 0.05). Furthermore, the ratio of Epo/EpoR was significantly lower in ADHD patients than controls (p < 0.05). Receiver operator characteristic curve analysis showed high diagnostic performance for Epo and EpoR, areas under curve were 0.980 and 1.000, respectively. Conclusion: This is the first report to investigate the association between serum Epo and EpoR levels in ADHD patients. Our results indicated that Epo may play a role in the etiology of ADHD, and Epo therapy may be beneficial in these disorders if given in addition to the routine treatment of children with ADHD. Furthermore, our results reveal possible diagnostic value of Epo and EpoR.

Distant local-guided tour perceptions and experiences of online travellers
(Sage Journals, 2022) Seyitoğlu, Faruk; Atsız, Ozan; 11.02. Department of Tourism Guidance / Turizm Rehberliği Bölümü; 11. Faculty of Tourism / Turizm Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
This paper investigated travellers’ perceptions and experiences of using distant local guided tours during the COVID-19 pandemic utilising a qualitative methodology. The reviews’ content of online travellers regarding distant local-guided tours offered by a sharing economy platform – Withlocals – in different destinations was analysed. The results demonstrated that travellers’ distant local-guided tour experiences include celebration, togetherness and socialising, escape and relaxation, memorable, educational, and hedonic components. Additionally, travellers perceived distant local-guided tours as an alternative travel type, preparation for an actual visit, and inspiration for face-to-face experiences. Therefore, distant local-guided tours can be defined as engaging alternative travel types that provide multidimensional experiences and help explore a destination before the in-person visit. Apart from playing a guidance role for scholars and practitioners, this research fills the gap of research on distant local-guided tours in the literature. However, future attempts could shed more light on the subject

Methods: This research was conducted between January 2015- July 2016 at the Neurosurgery Clinics of Turgut Özal İnönü University and Malatya State Hospital as a quasi-experimental research with pretest-posttest designs. The study population consisted of patients who were hospitalized in these clinics after operation of lumbar disc hernia. The sample group consisted of 112 patients selected with random sampling and stayed in these clinics after the power analysis (56 test, 56 control). This research data was collected between January 2016 - March 2016. Patient identification forms and visual analog scales (VAS) were used for data collection. Patient identification form was applied to the patients in the experimental group, after acupressure was applied to patients for 15-20 minutes, their level was determined with the VAS. When the acupressure was stopped, their pain was determined with the VAS. Whereas in the control group, their pain was determined with the VAS and taking the end of the time during which acupressure was applied to experimental group into consideration, their pain level was reevaluated in the 20th minute. Data were evaluated with percentage, arithmetic average, chi-square test and independent groups t test. Results: The research result showed that owing to the effect of acupressure the pain level of the experimental group decreased from 7.75±1.67 to 2.58±1.18. (p= .00). Conclusions: Hence this result suggests the effectiveness of acupressure on postoperatıve paın of lumbar disc hernia.

Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Background: Cardiac implantable electronic device (CIED) procedures are prone to complications. In our study, we investigated the effect of body mass index (BMI) on CIED-related complications. Methods: 1676 patients who had undergone CIED surgery (de novo implantation, system upgrade, generator change, pocket revision or lead replacement) at two heart centers in Turkey and met the study criteria were included in our study. For analysis of primary and secondary endpoints, patients were classified as non-obese (BMI < 25 kg/m2), overweight (25 ≤ BMI < 30 kg/m2), and obese (BMI ≥ 30 kg/m2). The primary endpoint was accepted as cumulative events, including the composite ofclinically significant hematoma (CSH), pericardial effusion or tamponade, pneumoth- orax, and infection related to the device system. Secondary outcomes included each component of cumulative events. Results: The rate of cumulative events, defined as primary outcome, was higher in the obese patient group, and we found a significant difference between the groups (3.0%, 4.3%, 8.9%, p = .001). CSH and pneumothorax rates were significantly higher in the obese patient group (0.3%, 0.9%, 1.9%, p = .04; 1.0%, 1.4%, 3.3%, p = .04, respectively). According to our multivariate model analysis; gender (OR:1.882, 95%CI:1.156–3.064, p = .01), hypertension (OR:4.768, 95%CI:2.470–9.204, p < .001), BMI (OR:1.069, 95%CI:1.012–1.129, p = .01) were independent predictors of cumulative events rates. Conclusions: Periprocedural complications associated with CIED (especially hematoma and pneumothorax) are more common in the group with high BMI.

Effects of Phubbing: Relationships With Psychodemographic Variables
(SAGE, 2020) Ergün, Naif; Göksu, İdris; Sakız, Halis; 02.10. Department of Psychology / Psikoloji Bölümü; 02.04. Department of Educational Sciences / Eğitim Bilimleri Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
The aim of this research is twofold: First, to adapt the Generic Scale of Phubbing and the Generic Scale of Being Phubbed into Turkish language and culture. Second, to investigate the relationships between phubbing, being phubbed, and various psychodemographic variables including anxiety, depression, negative self, somatization, hostility, loneliness, life satisfaction, and phone use duration. The two scales were adapted to Turkish with high psychometric properties, and the original item numbers were preserved. Analysis of the associations between variables showed that (1) phubbing was associated negatively with loneliness and positively with all other variables; (2) there was a strong relationship between phubbing and phone use duration; (3) somatization, satisfaction with life, and phone use duration predicted phubbing; (4) phubbing predicted all variables except satisfaction with life; (5) being phubbed was associated negatively with loneliness and satisfaction with life and positively with all other variables; and (6) anxiety, negative self, and hostility predicted being phubbed. This study is innovative for introducing two phubbing scales to Turkish and highlighting the psychological impact of phubbing on individuals.

Electrocatalysis property of CuZn electrode with Pt and Ru decoration
(International Journal of Hydrogen Energy, 2021) Toprak Döşlü, Serap; Döner, Ali; Yıldız, Reşit; 09.03. Department of Nutrition and Dietetics/ Beslenme ve Diyetetik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Electrocatalysis properties strongly depend on the interaction of metallic particles and this interaction enables to change the electronic structure of alloys which enhances the catalytic activity. This property is the key factor in the developing of cost-effective and efficient Hydrogen Evolution Reaction (HER) electrocatalysts for sustainable hydrogen production. In this study, novel electrocatalysts which are decorated with Pt and Ru have been developed for HER electrocatalysis. Microscopic analysis such as scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) and atomic force microscopy (AFM) are performed to determine the morphological and compositional structures. Electrocatalysis properties are evaluated by cathodic current-potential curves, electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) in 1.0 M KOH solution. Chronoamperometry (CA) and cycle tests are used for stability/durability of electrocatalysts. Results show that a small onset potential of the porous Cu/Ni/CuZn–Pt is obtained for HER. Exchange current density and polarization resistance are found to be 5.39 mA cm−2 and 2.0 Ω cm2 at overpotential of −100 mV for porous Cu/Ni/CuZn–Pt, respectively, indicating that Cu/Ni/CuZn–Pt is higher electrocatalytic properties than the others. Moreover, very low overpotentials at 10 and 40 mA cm−2 are obtained on porous Cu/Ni/CuZn–Pt compared with porous Cu/Ni/CuZn–Ru and Cu/Ni/CuZn. Porous Cu/Ni/CuZn–Pt also displays excellent stability/durability in test solution. The remarkable electrocatalysis properties of porous Cu/Ni/CuZn–Pt can be explained due to high porous structure, leaching of Zn from the deposit, intrinsic activity of Pt as well as changing in the electronic structure. It should be considered that porous Cu/Ni/CuZn–Pt is of high corrosion resistance in test solution for 120 h, which makes it good candidate for HER.

Microscopic analysis such as scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) and atomic force microscopy (AFM) are performed to determine the morphological and compositional structures. Electrocatalysis properties are evaluated by cathodic current-potential curves, electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) in 1.0 M KOH solution. Chronoamperometry (CA) and cycle tests are used for stability/durability of electrocatalysts. Results show that a small onset potential of the porous Cu/Ni/CuZnePt is obtained for HER. Exchange current density and polarization resistance are found to be 5.39 mA cm2 and 2.0 U cm2 at overpotential of 100 mV for porous Cu/Ni/CuZnePt, respectively, indicating that Cu/Ni/CuZnePt is higher electrocatalytic properties than the others. Moreover, very low overpotentials at 10 and 40 mA cm2 are obtained on porous Cu/ Ni/CuZnePt compared with porous Cu/Ni/CuZneRu and Cu/Ni/CuZn. Porous Cu/Ni/CuZn ePt also displays excellent stability/durability in test solution. The remarkable electrocatalysis properties of porous Cu/Ni/CuZnePt can be explained due to high porous structure, leaching of Zn from the deposit, intrinsic activity of Pt as well as changing in the electronic structure. It should be considered that porous Cu/Ni/CuZnePt is of high corrosion resistance in test solution for 120 h, which makes it good candidate for HER.

The aim of this study was to protect stainless steel against corrosion via poly (indole-co-aniline) with the help of titanium dioxide pre-coating. Different monomer ratios (1:1 and 1:9) wereapplied in order to determine the suitable chain composition to synthesize the copolymer in lithiumperchlorate containing acetonitrile. The structures, morphologies, electrochemical properties andcorrosion resistances of the mono and multi-layer coatings were investigated by Fourier-transform infrared spectra, scanning electron microscope, energy dispersive X-ray spectrometer,electrochemical impedance spectroscopy and anodic polarization. Furthermore the geometric struc-ture and electronic properties of indole, aniline, and indole-co-aniline (dimmer) molecules have beeninvestigated by quantum calculations. The results indicated that corrosion protection of copolymerswas increased via titanium dioxide pre-coating. The 1:1 copolymer coating showed better corrosionprevention than 1:9 coating. The correlation was determined between experimental and theoreticalparameters.
