Article Citation - WoS: 6Citation - Scopus: 11Activated Carbon-Coated Iron Oxide Magnetic Nanocomposite (ionps@ctac) Loaded With Morin Hydrate for Drug-Delivery Applications(Frontiers Media Sa, 2024) Dogan, Yusuf; Ozic, Cem; Ertas, Erdal; Baran, Ayse; Rosic, Gvozden; Selakovic, Dragica; Eftekhari, Aziz; 06.02. Department of Plant Protection / Bitki Koruma Bölümü; 06. Faculty of Agricultural Sciences and Technologies in Kızıltepe / Kızıltepe Tarım Bilimleri ve Teknolojileri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiCancer is a major disease that affects millions of people around the world every year. It affects individuals of all ages, races, and backgrounds. Since drugs used to treat cancer cannot distinguish between cancerous and healthy cells, they cause systemic toxicity along with serious side effects. Recently, controlled drug-release systems have been developed to reduce the side effects caused by anticancer drugs used for treatment. Morin is an anticancer drug with a flavonol structure. It has been extensively researched for its antioxidant, anti-inflammatory, antitumoral, and antibacterial properties, especially found in Chinese herbs and fruits, and its multiple positive effects on different diseases. In this study, a nanocomposite with magnetic properties was synthesized by coating biocompatible activated carbon obtained using the fruits of the Celtis tournefortii plant on the surface of iron oxide magnetic nanoparticles. Characterization of the synthesized activated carbon-coated iron oxide magnetic nanocomposite was confirmed by Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray spectrometry, X-ray diffraction, dynamic light scattering, zeta potential, and vibrating sample magnetometry. The cytotoxic effects of the drug-loaded magnetic nanocomposite were examined in HT-29 (colorectal), T98-G (glioblastoma) cancer cell lines, and human umbilical vein endothelial cell (HUVEC) healthy cell line. The morin loading and release behavior of the activated carbon-coated iron oxide magnetic nanocomposite were studied, and the results showed that up to 60% of the adsorbed morin was released within 4 h. In summary, activated carbon-coated iron oxide magnetic nanocomposite carriers have shown promising results for the delivery of the morin drug.Article Citation - WoS: 48Citation - Scopus: 51Adolescent Transport and Unintentional Injuries: a Systematic Analysis Using the Global Burden of Disease Study 2019(Elsevier Sci Ltd, 2022) Peden, Amy E.; Cullen, Patricia; Francis, Kate Louise; Moeller, Holger; Peden, Margaret M.; Ye, Pengpeng; Ivers, Rebecca Q.Background Globally, transport and unintentional injuries persist as leading preventable causes of mortality and morbidity for adolescents. We sought to report comprehensive trends in injury-related mortality and morbidity for adolescents aged 10-24 years during the past three decades. Methods Using the Global Burden of Disease, Injuries, and Risk Factors 2019 Study, we analysed mortality and disability-adjusted life-years (DALYs) attributed to transport and unintentional injuries for adolescents in 204 countries. Burden is reported in absolute numbers and age-standardised rates per 100 000 population by sex, age group (10-14, 15-19, and 20-24 years), and sociodemographic index (SDI) with 95% uncertainty intervals (UIs). We report percentage changes in deaths and DALYs between 1990 and 2019. Findings In 2019, 369 061 deaths (of which 214337 [58%] were transport related) and 31.1 million DALYs (of which 16.2 million [52%] were transport related) among adolescents aged 10-24 years were caused by transport and unintentional injuries combined. If compared with other causes, transport and unintentional injuries combined accounted for 25% of deaths and 14% of DALYs in 2019, and showed little improvement from 1990 when such injuries accounted for 26% of adolescent deaths and 17% of adolescent DALYs. Throughout adolescence, transport and unintentional injury fatality rates increased by age group. The unintentional injury burden was higher among males than females for all injury types, except for injuries related to fire, heat, and hot substances, or to adverse effects of medical treatment. From 1990 to 2019, global mortality rates declined by 34.4% (from 17.5 to 11.5 per 100 000) for transport injuries, and by 47.7% (from 15.9 to 8.3 per 100000) for unintentional injuries. However, in low-SDI nations the absolute number of deaths increased (by 80.5% to 42 774 for transport injuries and by 39.4% to 31 961 for unintentional injuries). In the high-SDI quintile in 2010-19, the rate per 100 000 of transport injury DALYs was reduced by 16.7%, from 838 in 2010 to 699 in 2019. This was a substantially slower pace of reduction compared with the 48.5% reduction between 1990 and 2010, from 1626 per 100 000 in 1990 to 838 per 100 000 in 2010. Between 2010 and 2019, the rate of unintentional injury DALYs per 100 000 also remained largely unchanged in high-SDI countries (555 in 2010 vs 554 in 2019; 0.2% reduction). The number and rate of adolescent deaths and DALYs owing to environmental heat and cold exposure increased for the high-SDI quintile during 2010-19. Interpretation As other causes of mortality are addressed, inadequate progress in reducing transport and unintentional injury mortality as a proportion of adolescent deaths becomes apparent. The relative shift in the burden of injury from high-SDI countries to low and low-middle-SDI countries necessitates focused action, including global donor, government, and industry investment in injury prevention. The persisting burden of DALYs related to transport and unintentional injuries indicates a need to prioritise innovative measures for the primary prevention of adolescent injury.

Çalışmamızda akut akciğer ödemi tanısıyla hastaneye başvuran hastalarda IMRS’nin mortaliteyi tahmin edip edemeyeceğini belirlemeyi amaçladık. Yöntemler: Çalışmamıza akciğer ödemi tanısıyla başvuran 371 hasta dahil edildi. Hastaların IMRS’leri hesaplama aracı kullanılarak belirlendi ve hastalar belirlenen değere göre düşük, orta ve yüksek IMRS olmak üzere üç gruba ayrıldı. Bulgular: Çalışmamıza dahil edilen hastaların 208’i kadın, 163’ü erkek olup yaş ortalaması 68,7 idi. Hasta grupları arasında hem 1 aylık hem de 1 yıllık mortalite oranları açısından istatistiksel olarak anlamlı farklılık vardı. Ayrıca hastane içi, 1 aylık ve 1 yıllık mortalite gelişen hastalar ile hayatta kalanlar arasında IMRS açısından anlamlı fark vardı. ROC analizinde IMRS için kesme noktasının 15,5 olması hem 1 yıllık hem de 1 aylık mortaliteyi öngörüyordu. Kaplan-Meier analizinde en yüksek mortalite riski IMRS yüksek grupta, en düşük mortalite riski ise IMRS düşük grupta gözlendi. Sonuç: Araştırma sonuçlarımız, IMRS’nin akut akciğer ödemi tanısıyla hastaneye yatırılan hastalarda hem kısa hem de uzun vadeli mortaliteyi güçlü bir şekilde öngördüğünü göstermektedir.Article Citation - WoS: 17Citation - Scopus: 15Alpha-lipoic acid may ameliorate testicular damage by targeting dox-induced altered antioxidant parameters, mitofusin-2 and apoptotic gene expression(Andrologia, 2021) Güzel, Elif Erdem; Kaya Tektemur, Nalan; Tektemur, Ahmet; 09.02. Department of Midwifery/ Ebelik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiIn the study, the ameliorating effects of alfa lipoic acid (ALA) against doxorubicin-induced testicular apoptosis, oxidative stress and disrupted mitochondrial fusion were investigated in male rats. Rats were divided into four groups as control, doxorubicin (DOX), DOX + ALA and ALA. A single dose of 15 mg/kg DOX was administered i.p to the DOX and DOX + ALA groups. 50 mg/kg ALA was given to the DOX + ALA and ALA groups by oral gavage every other day. After 28 days, rat testes and serum samples were collected and analysed. Administration of DOX alone caused a decrease in body and relative testicular weights, seminiferous tubule diameter and germinal epithelium thickness, Johnsen's score and serum testosterone levels. DOX treatment led to severe testicular damage such as tubular degeneration, and atrophic tubules. Also, the activities of superoxide dismutase and glutathione peroxidase were reduced, while the level of malondialdehyde was increased in the testis. The mRNA levels of apoptotic-related genes (CASP3, TP53, BAX, BCL2) and apoptotic index were increased, while mitofusin-2 decreased. DOX caused an increase in CASP3 and a decrease in mitofusin-2 immunoreactivities. Treatment with ALA markedly improved all of DOX-induced biochemical, histochemical and molecular alterations in rat testis. Consequently, ALA has a therapeutic role in ameliorating DOX-induced testicular damage in rats.Article Ameliorative Effects of Agomelatine Against Doxorubicin-Induced Hepatotoxicity(BMC, 2025) Savas, Hasan Basri; Sozen, Mehmet Enes; Cuce, Gokhan; Batur, TubaDrug-induced hepatotoxicity is a significant impediment to the use of doxorubicin, a commonly employed chemotherapeutic agent with established efficacy in cancer treatment. The present study aimed to determine the potential protective effects of agomelatine against doxorubicin hepatotoxicity in rat toxicity models. Thirty-two rats were divided into four groups: control (with saline administration), Doxo (with 40 mg/kg doxorubicin administration), Doxo + Ago20, and Doxo + Ago40 (with 20 and 40 mg/kg agomelatine administration and 40 mg/kg doxorubicin administration). On the day of 14 rats were sacrificed, samples were collected for comparison of immunohistochemical, hematological, and biochemical analysis. There were statistically significant differences between the study groups in terms of immunohistochemical, hematological, and biochemical parameters. Agomelatine administration reduced the TNF-alpha, and caspase-3, which increased by doxorubicin, and reversed levels of oxidative stress markers altered by doxorubicin (p < 0.05). Doxorubicin induces oxidative stress, apoptosis, and hepatotoxicity. Agomelatine may be favored as a primary antidepressant to mitigate hepatic damage induced by doxorubicin.Article An Examination of the Effects of Propolis and Quercetin in a Rat Model of Streptozotocin-Induced Diabetic Peripheral Neuropathy(Mdpi, 2024) Tueredi, Sibel; Celik, Hakim; Dagli, Seyda Nur; Taskin, Seyhan; Seker, Ugur; Deniz, MustafaThe purpose of this study was to reveal the combined effects of propolis (P) and quercetin (Q) against diabetic peripheral neuropathy developing with streptozotocin-induced diabetes in rats. Sixty-four adult male rats were divided into eight equal groups: control, P (100 mg/kg/day), Q (100 mg/kg/day), P + Q (100 mg/day for both), diabetes mellitus (DM) (single-dose 60 mg/kg streptozotocin), DM + P, DM + Q, and DM + P + Q. The rats were sacrificed, and blood and sciatic nerve tissues were collected. Blood glucose and malondialdehyde (MDA) levels increased, while IL-6 and total antioxidant status decreased in the DM group (p = 0.016 and p = 0.047, respectively). Ultrastructural findings showed degeneration of the axon and myelin sheath. The apoptotic index (AI %), TNF-alpha, and IL-1 beta immunopositivity increased significantly in the DM group (p < 0.001). Morphological structures approaching those of the controls were observed in the DM + P, DM + Q, and DM + P + Q groups. Morphometric measurements increased markedly in all treatment groups (p < 0.001), while blood glucose and MDA levels, AI (%), TNF-alpha, and IL-1 beta immunopositivity decreased. In conclusion, the combined effects of propolis and quercetin in diabetic neuropathy may provide optimal morphological protection with neuroprotective effects by reducing hyperglycemia, and these may represent a key alternative supplement in regenerative medicine.Article Analysis of Adaptation Processes and Anxiety Levels of University Students Staying with Earthquake Survivor Families in State Dormitories(BMC, 2025) Dag, Ibrahim; Olgac, KadriyeBackground This study aimed to examine the adaptation processes and anxiety levels of university students living with earthquake survivor families placed in state dormitories after recent major earthquakes.
Materials and Methods A descriptive, cross-sectional quantitative study was conducted in a state dormitory between May and August 2023. A total of 108 students participated using the snowball sampling method. Data were collected through a Descriptive Characteristics Form and the Beck Anxiety Scale. Statistical analyses included descriptive statistics and linear regression using SPSS 25.0.
Results Among the participants, 49% reported increased frequency of contact with their families after the earthquake. Sharing the same dormitory space with earthquake-affected families led to limited personal space for 56%, emotional impact for 51%, and benefits such as emotional support for 56%. Additionally, 45% noted changes in their attitudes, 46% in their social lives, and 56% in their social responsibility awareness. Regression analysis showed that sharing the same environment with families explained 33.7% of the variance in Beck anxiety scores. A significant positive relationship was found between cohabitation with families and anxiety levels (B=0.337, p<0.001), where each unit increase in cohabitation was associated with a 5.379-point increase in anxiety scores.
Conclusions The findings indicate that post-earthquake family cohabitation significantly affects students' psychological and social well-being. Living in close proximity to affected family members increases anxiety levels. Providing psychological support services for students is crucial to reduce anxiety and facilitate post-disaster recovery and adaptation.Article Citation - WoS: 28Citation - Scopus: 34An 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 ÜniversitesiBackground: 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.Review Citation - WoS: 1Citation - Scopus: 1Anatolian Medicinal Plants as Potential Antiviral Agents: Bridging Traditional Knowledge and Modern Science in the Fight Against Covid-19 and Related Viral Infections(Tubitak Scientific & Technological Research Council Turkey, 2024) Tilkat, Engin; Jahan, Israt; Hoser, Ayse; Kaplan, Alevcan; Ozdemir, Oguzhan; Onay, Ahmet; 21.01. Department of Health and Nursing Services / Sağlık ve Bakım Hizmetleri Bölümü; 21. Vocational School of Health Services / Sağlık Hizmetleri Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiThe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was the cause of the coronavirus 2019 (COVID-19), commonly known as the coronavirus pandemic. Since December 2020, COVID-19 vaccines have been extensively administered in numerous countries. In addition to new antiviral medications, the treatment regimen encompasses symptom management. Despite sustained research efforts, the outbreak remains uncontrolled, with affected patients still lacking proper treatment. This review is a valuable asset for researchers and practitioners aiming to delve into the yet unexplored potential of Anatolian flora in the fight against COVID-19 and other viral infections. Numerous medicinal plants in Anatolia, such as thyme, sage, cannabis, oregano, licorice root, and Origanum sp., contain bioactive compounds with proven antiviral properties that have been used in the region for centuries. The rich legacy of traditional Anatolian medicine (TAM), has significantly influenced modern medicine; thus, the profusion of medicinal plants native to Anatolia holds promise for antiviral drug development, making this review essential for researchers and practitioners.Article Citation - WoS: 30Citation - Scopus: 29Ancient DNA from Mesopotamia suggests distinct Pre-Pottery and Pottery Neolithic migrations into Anatolia(Science, 2022) Acar, Ayşe; Lazaridis, Iosif; Alpaslan-Roodenberg, Songül; Açıkkol, Ayşen; Agelarakis, Anagnostis; Davtyan, Ruben; 02.01. Department of Anthropology / Antropoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiWe present the first ancient DNA data from the Pre-Pottery Neolithic of Mesopotamia (Southeastern Turkey and Northern Iraq), Cyprus, and the Northwestern Zagros, along with the first data from Neolithic Armenia. We show that these and neighboring populations were formed through admixture of pre-Neolithic sources related to Anatolian, Caucasus, and Levantine hunter-gatherers, forming a Neolithic continuum of ancestry mirroring the geography of West Asia. By analyzing Pre-Pottery and Pottery Neolithic populations of Anatolia, we show that the former were derived from admixture between Mesopotamian-related and local Epipaleolithic-related sources, but the latter experienced additional Levantine-related gene flow, thus documenting at least two pulses of migration from the Fertile Crescent heartland to the early farmers of Anatolia.Article Citation - WoS: 21Citation - Scopus: 27Antibiotic Removal from the Aquatic Environment with Activated Carbon Produced from Pumpkin Seeds(Molecules, 2022) Alacabey, İhsan; 21.02. Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü; 21. Vocational School of Health Services / Sağlık Hizmetleri Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAntibiotics are among the most critical environmental pollutant drug groups. Adsorption is one of the methods used to eliminate these pollutants. In this study, activated carbon was produced from pumpkin seed shells and subsequently modified with KOH. The adsorbent obtained through this procedure was used to remove ciprofloxacin from aqueous systems. Fourier Transform-Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), elemental, X-ray Photoelectron Spectroscopy (XPS), Brunauer–Emmett–Teller (BET) and Zeta analyses were used to characterize the adsorbent. The surface area, in particular, was found to be a very remarkable value of 2730 m2/g. The conditions of the adsorption experiments were optimized based on interaction time, adsorbent amount, pH and temperature. Over 99% success was achieved in removal operations carried out under the most optimal conditions, with an absorption capacity of 884.9 mg·g−1. In addition, the Langmuir isotherm was determined to be the most suitable model for the adsorption interactionArticle Citation - WoS: 4Citation - Scopus: 4Antibiotic Resistance and Mortality in Icu Patients: a Retrospective Analysis of First Culture Growth Results(Mdpi, 2025) Kilinc, Metin; Department of Surgical Medical Sciences / Cerrahi Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiObjectives: This study aimed to analyze the antibiotic resistance patterns of microorganisms isolated from intensive care unit (ICU) patients and evaluate their impact on mortality and length of ICU stay. Given the increasing prevalence of multidrug-resistant (MDR) pathogens in critically ill patients, understanding their resistance profiles is crucial for optimizing empirical antibiotic therapy and improving patient outcomes. Methods: This retrospective study included 237 ICU patients admitted between 1 July 2022, and 1 January 2024. The initial culture growth results from blood and urine samples were analyzed. Microorganism identification was performed using VITEK 2 Compact and conventional bacteriological methods, while antibiotic susceptibility testing followed CLSI 2022 and EUCAST 2022 guidelines. Results: A total of 237 ICU patients were included in this study. The most frequently isolated microorganisms were Escherichia coli (E. coli) (44.3%), Klebsiella pneumoniae (K. pneumoniae) (35.0%), and Pseudomonas aeruginosa (P. aeruginosa) (25.3%), with Acinetobacter baumannii (A. baumannii) (31.2%) being the most resistant pathogen. Among Gram-positive bacteria, methicillin-resistant Staphylococcus aureus (MRSA) (12.2%) and vancomycin-resistant enterococci (VRE) (21.5%) were the most frequently identified multidrug-resistant (MDR) pathogens. Regarding antimicrobial resistance, carbapenem resistance was highest in A. baumannii (55%), followed by P. aeruginosa (40%) and K. pneumoniae (30%). Additionally, ESBL-producing E. coli (43.2%) and K. pneumoniae (38.5%), as well as carbapenemase-producing K. pneumoniae (18.6%) and E. coli (9.2%), were identified as key resistance mechanisms impacting clinical outcomes. Patients with MDR infections had significantly longer ICU stays (p < 0.05) and higher mortality rates. The Kaplan-Meier survival analysis revealed that A. baumannii infections were associated with the highest mortality risk (HR: 4.6, p < 0.001), followed by MRSA (HR: 3.5, p = 0.005) and P. aeruginosa (HR: 2.8, p = 0.01). Among laboratory biomarkers, elevated procalcitonin (>= 2 ng/mL, OR: 2.8, p = 0.008) and CRP (>= 100 mg/L, OR: 2.2, p = 0.01) were significantly associated with ICU mortality. Additionally, patients who remained in the ICU for more than seven days had a 1.4-fold increased risk of mortality (p = 0.02), further emphasizing the impact of prolonged hospitalization on adverse outcomes. Conclusions: MDR pathogens, particularly A. baumannii, MRSA, P. aeruginosa, and K. pneumoniae, are associated with longer ICU stays and higher mortality rates. Carbapenem, cephalosporin, fluoroquinolone, and aminoglycoside resistance significantly impact clinical outcomes, emphasizing the urgent need for antimicrobial stewardship programs. ESBL, p-AmpC, and carbapenemase-producing Enterobacterales further worsen patient outcomes, highlighting the need for early infection control strategies and optimized empirical antibiotic selection. Biomarkers such as procalcitonin and CRP, alongside clinical severity scores, serve as valuable prognostic tools for ICU mortality.Article Citation - WoS: 1Citation - Scopus: 1Antioxidant Properties of allium Turcicum Özhatay & Cowley Plant Extract, Its Effects on the Proliferation and Migration of Cancer Cells(Frontiers Media Sa, 2024) Ipek, Polat; Baran, Ayse; Cebe, Deniz Baris; Ahmadian, Elham; Eftekhari, Aziz; Baran, Mehmet Firat; 21.02. Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü; 21. Vocational School of Health Services / Sağlık Hizmetleri Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiCancer is a type of non-communicable disease that is responsible for numerous deaths worldwide. Cancer incidence and mortality rates are on the rise due to a combination of factors, such as a growing population, aging, and poor dietary habits. The Allium turcicum & Ouml;zhatay & Cowley plant is an endemic plant in the area where it grows and is consumed by the public due to its various benefits. This endemic plant, which generally grows in high-altitude regions, is sold in bunches because it is costly, mixed with rock salt, crushed into powder, and consumed as a spice. The cytotoxic and growth-inhibitory effects of A. turcicum & Ouml;zhatay & Cowley herb extract on human glioblastoma U373 cells, human colorectal carcinoma cell HCT-116, and healthy HUVEC cell lines were determined by the MTT method. After 24 and 48 h of application, logIC50 values in HUVEC, HCT-116, and U373 cells were defined as 3.737, 3.765; 3.513, 3.696, 4.476, and 4.104 mu g/mL, respectively. We conducted a cell migration experiment to study the A. turcicum & Ouml;zhatay & Cowley Extract (AT & Ouml;CE) impact on cancer cells' metastatic behavior. Our findings indicate that AT & Ouml;CE has an inhibitory effect on the migration potential of the cells used in the study. We conducted experiments using DPPH, ABTS, CUPRAC, and total phenolic content to assess the antioxidant properties of AT & Ouml;CE. The findings from the antioxidant activity experiments revealed an activity level of 0.20 +/- 0.046 at IC50. Additionally, the total phenolic content was measured to be 0.26 +/- 0.044 mg GAE/g.Article Antioxidant, Ache Inhibitory, and Anticancer Effects of Verbascum Thapsus Extract(C M B Assoc, 2023) Zhang, Na; Baran, Ayse; Valioglu, Ferzane; Teng, Lei; Atalar, Mehmet Nuri; Keskin, Cumali; Beilerli, AferinVerbascum thapsus (Mullein) is a medicinal plant used in folk medicine to treat various ailments. For this study, the biological functions of Verbascum thapsus (VT) methanol extract were determined in vitro. The plant's methanol extract was created through the maceration process. The phytochemical composition of plant extracts was investigated using liquid chromatography-electrospray ionization tandem mass spectrometry. The antioxidant capacity of the extract was determined using the 2,2-diphenyl-1-picrylhydrazil (DPPH radical) and 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS radical). Cell lines Caco-2 (human colorectal adenocarcinoma cells), LNCaP (Lymph Node Carcinoma of Prostate), and HEK293 (Human embryonic kidney 293 cells) were used to model colon, prostate, and non-cancerous cells. The cytotoxic activity of the plant extract on the proliferation of these cells was determined by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a tetrazole) assay protocol. VT extract showed moderate DPPH and ABTS radical scavenging activities at 30 mg/ml concentration. With this, VT extract was determined to inhibit acetylcholinesterase (AChE) enzyme and had strong cytotoxic activity on cancerous cell lines. In addition, our findings clearly showed that the plant extract had greater cytotoxic activity on the viability of cancerous cells compared to non-cancerous (Human embryonic kidney cells; HEK293) cells. The current findings showed that V. thapsus might be a promising anti-cancer medication candidate for the treatment of human colorectal adenocarcinoma and colon cancer, as well as a good source antioxidans.

Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü; 21. Vocational School of Health Services / Sağlık Hizmetleri Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBackground: Cancer is an unnatural type of tissue growth in which the cells exhibit unrestrained division, leading to a progressive increase in the number of dividing cells. It is now the second largest cause of death in the world. The present study concerned antioxidant, anticancer and anticholinesterase activities and protocatechuic, catechin, caffeic acid, syringic acid, p-coumaric acid and o-coumaric concentrations in methanol extracts of flowers, fruits and seeds of Hypericum amblysepalum. Materials and Methods: Antioxidant properties including free radical scavenging activity and reducing power, and amounts of total phenolic compounds were evaluated using different tests. Protocatechuic, catechin, caffeic acid, syringic acid, p-coumaric acid and o-coumaric concentrations in extracts were determined by HPLC. Cytotoxic effects were determined using the MTT test with human cervix cancer (HeLa) and rat kidney epithelium cell (NRK-52E) lines. Acetyl and butyrylcholinesterase inhibitory activities were measured by by Ellman method. Results: Total phenolic content of H. amblysepalum seeds was found to be higher than in fruit and flower extracts. DPPH free radical scavenging activity of the obtained extracts gave satisfactory results versus butylated hydroxyanisole and butylated hydroxytoluene as controls. Reducing power activity was linearly proportional to the studied concentration range: 10-500 µg/mL LC50 values for H. amblysepalum seeds were 11.7 and 2.86 respectively for HeLa and NRK-52E cell lines. Butyryl-cholinesterase inhibitory activity was 76.9 ± 0.41 for seed extract and higher than with other extracts. Conclusions: The present results suggested that H. amblysepalum could be a potential candidate anti-cancer drug for the treatment of human cervical cancer, and good source of natural antioxidants.Article Ascorbic Acid Exhibits More of a Protective Effect Than Estradiol Against Nephrotoxicity Induced by Malathion in Rats: A Histopathological and Molecular Docking Study(Tubitak Scientific & Technological Research Council Turkey, 2025) Alhilal, Suzan; Albakoush, Ahmed; Farag, Bassant; M.gomha, Sobhi; Alhılal, Mohammad; Salem, Mahmoud Elsayed MohamedBackground/aim: Despite the known harmful effects associated with malathion toxicity in various organs, it continues to be widely used for plant protection and insect control. This study is the first to compare the protective effects of estradiol and ascorbic acid against malathion-induced nephrotoxicity through histopathological assessment and molecular docking analyses. Materials and methods: This study was conducted using 20 female albino rats that were distributed into sham, malathion, malathion + estradiol, and malathion + ascorbic acid groups. Nephrotoxicity was induced by daily treatment with malathion and the effects of estradiol and ascorbic on nephrotoxicity were evaluated. After 4 weeks of treatment, the animals were sacrificed and the kidneys were examined following hematoxylin and eosin (H&E) staining. Histopathology results were supported by molecular docking studies of estradiol and ascorbic acid against a target protein (PDB ID: 2YMX), the peptide inhibitor Fab408 inhibiting acetylcholinesterase (AChE). The inhibition of AChE is the primary mechanism of the toxic effects of malathion. Results: Histopathological examination revealed a notable elevation (p < 0.001) in degeneration and necrosis within the tubular epithelium and interstitial nephritis in the malathion group compared to the sham group. Daily administration of estradiol and ascorbic acid resulted in a notable reduction (p = 0.0022) in the severity of these histopathological changes in the malathion + estradiol and malathion + ascorbic acid groups compared to the malathion group. Of these, the most significant decreases were observed in the malathion + ascorbic acid group. Docking studies of these compounds against the selected protein (PDB ID: 2YMX) revealed promising binding scores. Ascorbic acid exhibited the highest docking score (–6.44 kcal/mol), indicating a favorable binding interaction with this protein. Conclusion: Estradiol and ascorbic acid exert protective effects against malathion-induced nephrotoxicity, whereas ascorbic acid showed superior efficacy compared to estradiol. This result was further supported by molecular docking studies.Article Assessment of Children Exposed to Maras Powder Intoxication(Folia Medica, 2020) Dalkiran, Tahir; Özaslan, Mehmed Mustafa; Acipayam, Can; Kandur, Yaşar; Unsal, Velid; 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 ÜniversitesiIntroduction: A smokeless tobacco known as Maras powder (MP) is commonly consumed in the southern region of Turkey. To the extent of our knowledge, no previous study in literature has reported acute MP intoxication in children. Aim: Our aim was to determine the clinical effects and treatment strategies of MP poisoning in children.Materials and methods: We retrospectively reviewed the medical records of children <18 years of age with MP intoxication who were followed up in the Intensive Care Unit between January 2016 and April 2018 in our center. Results: Forty-one patients (M/F= 25/16) were included in this study. The mean age was 13.2±22.4 months (age range: 7 to 30 months). The patients presented with vomiting (n=23, 56%), cough (n=17, 41.5%), loss of consciousness (n=11, 26.8%), respiratory distress (n=6, 14.6%), convulsion (n=7, 17%), cyanosis (n=1, 2.4%), and abdominal pain (n=1, 2.4%) following oral ingestion of the substance. On their physical examination all patients with convulsion were in a comatose state. Thirty-two patients (78%) had tachycardia; 15 patients (36.5%) had pharyngeal hyperemia; and three (7.3%) had hiccups. Although the female patients had a lesser rate of symptoms than male patients, the difference was not statistically significant. Conclusions: Our aim was to inform the doctors about the clinical picture that develops after taking this substance and contribute to the understanding of the treatment approach.Article Citation - WoS: 1Citation - Scopus: 1Assessment of Iron Metabolism and Inflammation in Children With Cerebral Palsy(Mdpi, 2025) Orhan, Ozhan; Gokdemir, Gul Sahika; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBackground/Objectives: Cerebral palsy (CP) is a motor disorder resulting from brain damage that is common in childhood. Iron is vital for the body's basic functions. Iron metabolism disorders and inflammation contribute to the neurological complications seen in CP. The purpose of this research was to ascertain the association and correlation between markers of inflammation and iron metabolism in children with CP. Methods: A total of 181 children diagnosed with CP and 111 typically developing children were retrospectively included in the study. Demographic data, blood parameters, C-reactive protein, iron, total iron binding capacity, and inflammation markers were evaluated. Results: C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR) and systemic immuno-inflammatory index (SII) levels of CP children were found to be statistically significantly higher than those of control group children (p < 0.05). Iron (Fe) and ferritin levels were lower in the CP group, while total iron binding capacity (TIBC) was higher. Spearman correlation analysis showed significant correlations between iron, ferritin and TIBC and SII. Conclusions: Iron deficiency and chronic inflammation are associated with the pathophysiology of CP in patients with CP, and therefore it is important to monitor markers of iron metabolism and inflammation in these patients.Article Citation - WoS: 9Citation - Scopus: 10Assessment of renal function in obese and overweight children with ngal and kim-1 biomarkers(Nutricion Hospitalaria, 2020) Unsal, Velid; Gül, Ali; Yılmaz, Resul; Özmen, Zeliha Cansel; Demir, Osman; Gümüşer, Rüveyda; 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 ÜniversitesiAim and background:the incidence of obesity has increased among children, and obesity has been considered an independent risk factor for chronic kidney disease. We aimed to determine the degree of kidney function impairment by evaluating urine neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) levels. Materials and methods: in total, 15 obese, 26 overweight, and 26 control adolescents aged 10 to 16 years were enrolled into the study. Urine samples were evaluated for NGAL and KIM-1 levels using enzyme-linked immunosorbent assay kits. We investigated the association between obesity and related comorbidities with urinary NGAL and KIM-1 excretion. Results: no significant differences were noted between the obese, overweight, and control groups in urinary NGAL and KIM-1 excretion (p = 0.327 and p = 0.917, respectively). In the obese and overweight groups urinary NGAL levels were 50.39 [30.88-74.22] in females and 26.67 [23.24-45.59] in males (p = 0.013). Also, urinary NGAL levels were increased in obese and overweight adolescents with LDL dyslipidemia at 64.12 [30.98-114.32] as compared to those without LDL dyslipidemia: 39.51 [25.59.56.37] (p = 0.024). Furthermore, a correlation was observed between insulin and homeostasis model assessment of insulin resistance levels with the NGAL/creatinine ratio in the overweight group (r = 0.515; p = 0.008, and r = 0.483; p = 0.014, respectively). Such correlation was not found in the obese group. Conclusion: the effect of obesity on renal function could not be determined in children. A longer exposure may be required for obesity-induced disruption of renal function in children. Renal function may be disrupted by dyslipidemia in obese adolescents. Furthermore, obesity impaired renal function in female adolescents. The normalization of these urinary markers as related to urine creatinine should be discussed.Article Citation - WoS: 6Citation - Scopus: 5The association of allergic rhinitis severity with neutrophil-lymphocyte and platelet-lymphocyte ratio in children(Northern Clinics of İstanbul, 2022) Cansever, Murat; Sarı, Neslihan; Department of Surgical Medical Sciences / Cerrahi Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiObjective: The aim of the study was to investigate the relationship between the severity of allergic rhinitis (AR) and neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in pediatric patients. Methods: This study is a retrospective, cross-sectional, and observational study including 200 AR patients and 160 healthy controls. Of the patients, 39% were boys with a mean age of 10.5 years. The study included children with persistent and intermittent AR. Of the controls, 50.6% were boys with a mean age of 10.3 years. We compared NLR and PLR from blood test between study and control groups. They were also compared according to AR severity within the patient group. Results: The NLR was 1.64±1.29 in the study group whereas 1.18±0.31 in the control group. The PLR was 102.72±31.20 in the study group whereas 79.36±11.72 in the control group. When NLR and PLR were compared between groups, we found statistically significant differences in both NLR and PLR (p=0.003, p=0.001, respectively). We found a statistically significant difference when comparing both NLR and PLR in patients with intermittent and persistent AR. These rates increased with disease severity (p=0.000, p=0.000, respectively). Conclusion: Both NLR and PLR are useful markers for the diagnosis and severity of AR. Clinicians can use these markers to assess disease severity in pediatric patients at the beginning of the diagnostic process.
