(Soc Argentina Pediatria, 2024) Talay, Mehmet N.; Gungor, Emre; Orhan, Ozhan; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Introduction : Cyanide poisoning, whether it be accidental or intentional, remains a significant danger to adults and children, especially in societies where agriculture is a primary source of income. We examined the clinical follow-up, complications, and results of cyanide poisoning cases that occurred after eating the pits and seeds of plants containing cyanide glycosides, such as apricot kernels and almonds. Methods : Between 01/01/2017 and 01/08/2022, 14 children aged 1-18 years who were followed up with a prediagnosis of cyanide poisoning in our Paediatric Intensive Care Unit (PICU) were retrospectively analysed. Results : Eight of the patients followed with a preliminary diagnosis of cyanide poisoning were female and six were male. The most common admission month was July (42.8%) coinciding with the agricultural season. The most common symptoms at presentation were weakness and fatigue (n = 7). In the PICU, 4 patients presented lip cyanosis; 3, altered level of consciousness. Vomiting, seizure, headache, dizziness and palpitatons were less frequent. Four patients were treated with hydroxocobalamin (Cyanokit (R) ) as an antidote due to acidosis in their blood gases. All patients treated for cyanide poisoning were discharged. Conclusions : Cyanide poisoning should be considered in paediatric patients with suspicious findings, sudden loss of consciousness, increased anion gap acidosis and lactic acidosis. The history of eating the seeds of plants such as apricot and almonds should be investigated .

Animal Remains of Alaybeyi Hoyuk
(Tubitak Scientific & Technological Research Council Turkey, 2019) Siddiq, Abu Bakar; 02.01. Department of Anthropology / Antropoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
This paper presents the zooarchaeological observations on animal remains of Alaybeyi Hoyuk unearthed from 2016 and 2017 excavation sessions. Dated to 4721-4553 cal. BC, Alaybeyi stands so far as the oldest archaeological settlement discovered in northeast Anatolia. Therefore, the faunal assemblage at Alaybeyi offers great opportunity to study the status of animals and their relationships with humans in the largely unexplored Kars-Erzurum plateau covering a period from the Chalcolithic to Late Iron Age. Taxonomic and osteometric analyses show that, like the present day, cattle were dominant over caprines, revealing extensive cattle pastoralism in the region for at least about 7 millennia. While caprines too were significant in the subsistence strategy of local humans, there was not any sign of raising pigs. Significant numbers of wild species including carnivores, aquatic mammals, and rodents, as well as resident and migratory birds, were also hunted by Alaybeyi people. Additionally, horse burials, horse cult, dog burials, and a rich number of dog bones present animals as versatile actors in various ritual and symbolic practices at the site.

Mardin Artuklu University / Mardin Artuklu Üniversitesi
A new method for the determination of Cu(II) and Pb(II) by flame atomic absorption spectrometry (FAAS) after preconcentrating on a column containing Anoxybacillus sp. SO B1-immobilized Amberlite XAD-16 was developed. The functional groups of Anoxybacillus sp. SO B1 immobilized on Amberlite XAD-16 were characterized in KBr tablets by Fourier transform infrared (FT-IR) spectrometry. Various parameters such as pH, amount of the adsorbent, eluent type and volume, and flow rate of the sample solution were studied. The optimum pH values of quantitative sorption for Cu(II) and Pb(II) were found to be pH 7.0 and 5.0 and Cu(II) and Pb(II) ions could be quantitatively eluted with 5.0ml of 1.0mol L-1 HCI and 10.0ml of 0.25mol L-1 HNO3, respectively. Recoveries of Cu(II) and Pb(II) were found to be 100.9 +/- 1.57% and 100.3 +/- 0.49% (N = 5), the limits of detection of Cu(II) and Pb(II) in the determination by FAAS (3s, N = 10) were found to be 0.8 and 1.6 mu g L-1, respectively. The proposed enrichment method was applied for metal ion determination from water samples such as two parts of Tigris River water in Diyarbakir and Elazig, Lake of Hazar in Elazig, and tap water in Diyarbakir. Furthermore, the accuracy of the proposed method was verified by studying the analytical recovery and by analyzing certified reference material (NCS-DC 73350 leaves of poplar).

The aim of study was to evaluate the yield performance of genotypes and stability, environments and G x E interaction of 12 spring barley genotypes in multi-environment trials. The trials were implemented in respect to a integrate arrangement complex style with four replications. The AMMI (Additive main effects and multiplicative interaction) analysis was made to estimate grain yield and understand G x E interaction patterns. Analysis indicated that the major contributions to treatment sum of squares were environments (81.4%), GE (10.3%) and genotypes (8.3%), respectively; suggesting that grain yield of genotypes was effected environmental conditions. PCA 1 and PCA 2 axes (Principal component) were significant (0.01) and supplied to 68.30% of the complete G x E interaction. The AMMI analysis revealed that E3 and E5 were more stable and high productive; mean while E6 and E7 were unstable and nominal efficient environments. According to stability variance, the genotypes (G1, G3, G6 and G9) were the productive and more stable; meanwhile G4 and G5 were low productive and stable genotypes. Moreover, G2 were the best productive to all environments without E2. The G x E model exposed according to AMMI analysis recommended that G2 shown candidates and registered as Kendal, because of wide adaptability with high performances in all environments.

Nefis, akıl ve aşk itici güçleri arasında şekillenen insanın varoluş macerası, yine insanın dilsel dışavurum ürünleri olan edebî metinlere ve özellikle şiire büyük ölçüde yansımıştır. Bu dışavurum, farklı edebî geleneklerde yüzeysel farklılıklara sahip olmakla birlikte ortak bazı yönleri de ihtiva etmektedir. Klasik şiirde âşık-mâşuk-rakîb üçlüsü arasında cereyan eden aşk temasının İsmet Özel şiirinde de benzer biçimlerde tezahür ettiği söylenebilir. Klasik şiirde mecâzî ve hakîkî aşk arasında çoğu zaman sınırları belirsizleştiren, ayrımları anlamsızlaştıran bir geçişkenlik vardır. Özel’in şiirinde ise ideolojik hedeflerle tensel arzuların iç içe geçtiği, bunlar arasında keskin geçişlerin yaşandığı bir aşk söz konusudur. Klasik şiirde aşk, insanın tekâmül sürecinin önemli bir vasıtasıdır. Benzer şekilde İsmet Özel için de aşk, insanı varoluş atılımına sürükleyen bir harekettir. Diğer yandan klasik şiirde âşık kendi benliğini adeta yok ederek (fenâ) maşuğa kavuşurken İsmet Özel’in şiirinde güçlü bir “Ben” vurgusu dikkat çekmektedir. Ancak bu Ben’in aynı zamanda bir maşuk olarak anlaşılmasına fırsat veren ipuçları, klasik şiirde ve tasavvuf düşüncesinde bilinen âşık-maşuk bütünlüğü çerçevesinde meseleyi daha ilginç bir boyuta taşımaktadır. Bu makale, klasik şiir ile İsmet Özel şiirindeki aşk anlayışını ve âşık, mâşuk, rakîb tezahürlerini mukayeseli bir şekilde ele almayı, benzerlikleri ve farklılıkları tespit ve tahlil etmeyi amaçlamaktadır.

Assessing the Prognostic Value of Halp Score in Peripheral Artery Disease: Correlation With Lesion Severity and Long-Term Mortality
(Sage Publications Ltd, 2025) Evsen, Ali; Aktan, Adem; Kilic, Raif; Yalcin, Abdulaziz; Ozbek, Mehmet; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Introduction Peripheral artery disease (PAD) poses a growing clinical challenge due to an aging population, despite advances in treatment methods. Various scoring systems have emerged to predict high-risk patients, including the HALP (hemoglobin, albumin, lymphocyte, and platelet) score, known for predicting prognosis in cancers and stroke. This study assesses the HALP score's relation to lesion severity and long-term mortality in PAD patients. Methods We retrospectively analyzed 305 symptomatic PAD patients undergoing endovascular intervention. The following formula was used to calculate the HALP score: hemoglobin (g/L) x albumin (g/L) x lymphocyte count (/L) / platelet count (/L). Lesion severity was classified by TASC-II: TASC AB and TASC CD. Mortality data were obtained from hospital and social security records. Results The study involved 305 patients (mean age 64.4 +/- 11.8 years; 72.1% male), divided into survivors (208) and non-survivors (97). ROC analysis identified HALP score as the strongest predictor of long-term mortality (AUC: 0.736; 95% CI: 0.679-0.793; p < .001). HALP score (HR, 0.087; 95% CI, 0.025-1.300; p < .001), age (p < .001), DM (p = .007), and CRP (p = .013) independently predicted mortality. Kaplan-Meier analysis showed higher HALP scores linked to lower long-term mortality (Log-rank: 20.102, p < .001), with an average follow-up of 48 +/- 18 months. Conclusion The HALP score emerged as a robust predictor of PAD prognosis, surpassing individual components and other parameters. Lower HALP scores correlated with more severe lesions and reduced life expectancy.

Assessment 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 Üniversitesi
Aim 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.

Study was planned in a descriptive design to examine how the empathic tendencies of students in the Faculty of Health Sciences affect their attitudes toward individuals who have different sexual orientations and was conducted with seven hundred and six students. The data collected online using the Student Information Form, Empathic Tendency Scale (ETS) and Attitudes Toward Lesbian and Gay Men Scale (ATLGS). Participants' mean scores were 62.98 +/- 18.79 on the ESS and 29.02 +/- 10.75 on the ATLGS. When the correlation between ETS and ATLGS scores was analyzed, a positive and moderate (p<0.05) correlation (r = 0.62) was found between ETS and ATLGS scores. These scores were moderate and the correlation between ETS and ATLGS scores was significant (F=438.585; p<0.05). Empathic disposition explained 38.3% of the total change in ATLGS level (R2=0.383) and increased ATLGS level (B=0.620). It was found that as students' empathic skills improved, their homophobic attitudes decreased.

The goal of the present study is to determine some of the biochemical compositions and antioxidant capacities of plant extracts in two endemic taxa for Turkey including T. cadmeum (Boiss.) Heywood subsp. orientale Grierson and T. nitens (Boiss. & Noë) Grierson together with T. polycephalum (L.) Sch.Bip subsp. argyrophyllum (K. Koch) Podlech, and T. parthenium (L.) Sch.Bip. The fatty acids were determined by using gas chromatography, while phenolics, lipid soluble vitamins and sterols were determined by using HPLC and radical scavenging activities, total phenolics, and FRAP were determined spectrophotometrically. It was found that Tanacetum taxa have palmitic acid (C16:0), and stearic acid (C18:0) as major saturated fatty acids and linoleic acid (C18:2 n6), α-linolenic acid (C18:3 n3) and oleic acid (C18:1 n9) as principal unsaturated fatty acids. It was found that Tanacetum taxa had more total unsaturated fatty acid contents (60.24±0.3%- 70.54±0.29%) than saturated fatty acids and it was found that T. parthenium had the highest total essential fatty acid composition (58.65%±0.59%). It was also reported that the omega6/omega3 ratio of T. cadmium subsp. orientale (8.22) differed from other taxa in this study. Also, the present study showed that Tanacetum had the lowest amount of lipid soluble vitamins. On the other hand, catechin was found to be the main polyphenolic compound in this study and it was determined that T. parthenium had the highest catechin (4479.1±5.71 µg/mg) and total phenolic contents (324.91±2.01 µgGAE/mg) in this study. Rutin was only determined in two endemic taxa T. cadmeum subsp. orientale (23±0.91 µg/mg), and T. nitens (5.7±0.27 µg/mg). Also, the naringenin, vanillic acid and caffeic acid amounts of the endemic T. cadmeum subsp. orientale and T. nitens were higher than other taxa in the study. In addition, it was determined that Tanacetum taxa had a high stigmasterol content. However, T. parthenium had a higher ergosterol content (271±2.36 µg/mg). It was also found that T. parthenium has highest D2, α-tocopherol, retinol acetate, ergosterol, and stigmasterol contents among the studied taxa. In addition, the study showed that Tanacetum taxa have strong DPPH and ABTS radical scavenging activities. It was concluded that Tanacetum taxa have potent antioxidant capacity.

(Corvinus Univ Budapest, 2019) Acay, H.; 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
Environmentally friendly methods for obtaining nanomaterials see a great interest. In addition to being inexpensive, the easy implementation process and the advantages of synthesis without toxic chemicals are the main reasons of interest. In this study, silver nanoparticles (AgNPs) were successfully synthesized using fig (Ficus carica) leaf extract. The formation and the presence of AgNPs were observed using ultraviolet-visible spectrophotometry (UV-Vis). Peaks with a maximum wavelength of 419 nm are identified in the measurements. Phytochemicals in the extract responsible for functional groups providing reduction and stability were evaluated using Fourier transform infrared spectroscopy (FT-IR) data. The Scanning electron microscopy-Energy Dispersive X-Ray Spectrum (SEM-EDX) analysis showed that the AgNPs were spherical and the elemental composition contained mostly silver. X-ray diffractometer (XRD) results revealed that the peaks 111 degrees, 200 degrees, 220 degrees and 311 degrees belong to the characteristic structure of silver and have a crystal dimension of 17.30 Nm using Debye-Scherrer equation. In thermogravimetric - differential thermal analysis (TGA-DTA) analysis, the degradation temperatures of AgNPs were evaluated. AgNPs showed antimicrobial activity on various microorganisms even at very high concentrations. As a solution to the antimicrobial search, it can be developed in medical industry.

The integration of the principles of green chemistry into nanotechnology has become one of the key issues in nanotechnology research. Metal nanoparticle production, which does not contain toxic chemicals and does not harm the environment, needs to be developed to avoid adverse effects on medical applications. In this study, Pleurotus eryngii (PE) extract was used for preparation of silver nanoparticles (AgNPs). The presence of AgNP was understood that after adding 1 mM silver nitrate (AgNO3) to the fungus extract, the reaction turned from the open yellow to reddish brown. The analysis of samples taken at different times with the UV-Visible Spectrophotometer (UV-Vis) confirms the formation of PE-AgNPs. The Scanning electron microscopy-Energy Dispersive X-Ray Spectrum (SEM-EDX) analysis showed that spherical nanoparticles were formed. X-ray crystallography (XRD), analysis is calculated from Debye-Sherers inequality, in which PE-AgNP synthesized in the study was 18.45 nm in size. It has been demonstrated by using the minimum Inhibitory Concentration (MX) method in which AgNPs have strong antimicrobial activity.

Silver nanoparticles (AgNPs) are valuable materials with a large number of sectors used. Green synthesis is very important for biomedical applications as they show biocompatible properties. In this study, AgNPs were easily synthesized using the environmentally friendly green synthesis approach using agricultural waste parts of Citrullus lanatus sp. plant grown in Diyarbakır region. Characterization of synthesized AgNPs was made. Fourier Transform Infrared Spectroscopy (FTIR) analysis was used to evaluate the phytochemicals responsible for effective reduction in the formation of AgNPs. UV-visible spectrophotometer (UV-Vis.) Spectra were also used to determine the presence of AgNPs. X-Ray Diffraction Diffractometer (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscope, Zeta potential analyzes were performed to define the crystal structures, dimensions and surface charges of AgNPs, respectively. In these data, it was determined that AgNPs showed maximum absorbance at 460 nm, spherical appearance, 21.27 crystal nano size and -30.05 mV zeta potential. Antimicrobial effects of AgNPs on gram positive Staphylococcus aureus (S. aureus) and Bacillus subtilis (B. subtilis) bacteria, gram negative Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa) bacteria, as well as on fungus C. albicans pathogenic microorganisms It was analyzed by specifying the Minimum Inhibition Concentration (MIC) by microdilution.
