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
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.

(Journal of Urological Surgery, 2018) Kölükçü, Engin; Kılıç, Şahin; Atılgan, Doğan; Parlaktaş, Bekir; Ceylan, Salih; Unsal, Velid; Etikan, İlker
Objective: The association of preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with postoperative tumor stage and Fuhrman nuclear grade was investigated in patients with renal cell carcinoma (RCC). Materials and Methods: Data of 123 patients, who were operated due to RCC, in our clinic was analysed. NLR and PLR were evaluated in patients who were classified according to tumor stage (T1 and T2 low stage, T3 and T4 high stage) and Fuhrman nuclear grade (grade 1 and 2 low-grade, grade 3 and 4 high-grade). NLR and PLR were compared using Levene’s test between the groups. Results: Sixty four patients were female (52.1%) and 59 were male (47.9%). All haematological parameters were expressed as 103 /μL. Mean age, blood neutrophil, lymphocyte and platelet counts, and NLR and PLR values of the patients were 62.49±12.43 years, 6.27±2.8, 2.05±0.83, 263.72±89.03, 4.01±3.93, and 149.73±82.1, respectively. The most common histologic subtype was recorded as clear cell RCC (76.4%). NLR and PLR were 3.83±3.22 and 142.79±66.66, respectively in the low-stage group and 4.43±5.29 and 165.85±109.41, respectively in the high stage group. As for the Fuhrman nuclear grading, NLR and PLR were 3.81±3.45 and 146.63±87.36, respectively in the low-grade group and 4.61±5.387 and 159.32±63.42 in the high-grade group. There was no statistically significant difference between the groups (p>0.05). Conclusion: Although not statistically significant, high tumor stage and nuclear grade were positively correlated with NLR and PLR. It is concluded that, further multi-center and prospective studies with larger samples are needed to derive meaningful results.

(Cukurova Medical Journal, 2021) Sarı, Neslihan; Arslan, Nurgül; Bayram Değer, Vasfiye
Purpose: Several atypical presentations of COVID-19 like anosmia, conjuctivitis, and gastrointestinal findings are seen in the literature. The purpose of this study was to investigate the common and atypical symptoms of COVID-19 among the patients admitted to the otorhinolaryngology (ENT) outpatient clinic. Materials and Methods: This case series was conducted with 49 patients who applied to hospital between April 1, 2020 and April 30, 2020. Common and atypical otolaryngological findings were recorded. Sociodemographic findings and blood parameters were also evaluated. Results: Of the patients, 59.18% were aged 40 and over, 46.94% were of the A blood group, 55.10% were male and 24.49% were smokers, 51.02% had a chronic disease. Among typical symptoms; fever (71.43%), a dry cough (46.94%), shortness of breath (42.86%) was seen. Diarrhea (48.98%), runny nose (51.02%), nasal congestion (42.85%), sore throat (22.44%), headaches (32.65%), 18.36% olfactory disorder, 26.53% gustatory disturbance were noted. Olfactory and gustatory disturbances are found to be related to good prognosis and mild clinical course. The difference between Hg and D–dimer levels of the female and male patients were found to be statistically significant. The D-dimer levels determined in the present study were higher than those reported in the literature. Conclusion: While COVID-19 present with common symptoms, sometimes atypical symptoms can be the only finding during initial application to the hospital. Olfactory and gustatory disturbances point to the effects of COVID-19 on neurons. Neuronal effects like olfactory and gustatory disturbances should be closely monitored in COVID-19 patients in long term.

(Yükseköğretim Dergisi, 2021) Koç, Gülten; Yücel Özçırpan, Çiğdem; Terzioğlu, Füsun; Şimşek Çetinkaya, Şahika; Uslu-Şahan, Fatma; Akın Işık, Rabiye; Evrenol Öçal, Simge; Cansu Akdağ Topal, Merve Mert Karadaş, Sevda Yıldırım Hamurcu, Pınar Uzunkaya Öztoprak , Ayşe Sevim Akbay Kıs, İlknur Atasever, Safiye Özkan, Beril Nisa Yaşar, Esra Başkaya
This study aims to determine the effect of a university elective course focusing on gender on students' gender attitudes, critical thinking dispositions, and media literacy skills. The research design was quasi-experimental, and the study was conducted with a pretest/posttest control group. The sample of the study consisted of 74 students who took a course on gender during the fall semester of the 2016-2017 academic year and 70 students who had similar characteristics but did not receive the course. In the pretest and posttest evaluation conducted in the first week and the last week of the semester, respectively, the Student Information Form, the Gender Roles Attitude Scale (GRAS), the Critical Thinking Dispositions Scale (CTDS), and the Media Literacy Scale (MLS) were administered to the students in both groups. The Course Satisfaction Assessment Form was administered at the end of the term to the students who enrolled for the gender course. The GRAS scores of the experimental group increased at the end of the course (p<0.05). The GRAS total mean scores of both the groups were similar in the pretest, but there was a statistically significant difference between their total mean scores in the posttest (p<0.05). This study recommends more comprehensive and long-term studies on integrating a gender course into the university curriculum, which will help develop students' critical thinking disposition and media literacy skills and raise awareness of gender equality among students.

(2018) Kaçar, Semra; Başhan, Mehmet; Oymak, Ahmet
The present study investigated the lipid content and FA profiles of total lipids, phospholipids (PL) and triacylglycerols (TAG) of Mastacembelus mastacembelus from the Atatürk Dam Lake (Turkey). The results showed that the total lipid content of the dorsal muscle varied seasonally from 0.50% to 3.59%. Wide ranges of saturated fatty acids (SFAs) (36.21 to 50.52%) and polyunsaturated fatty acids (PUFAs) (25.22 to 42.02%) were found in the PL fraction. However, higher monounsaturated fatty acids (MUFAs) (37.63 to 45.07%) and SFA (34.71 to 38.82%) were found in TAG (triacylglycerol). The ratios of ω-3 to ω-6 PUFA ranged from 0.65 to 1.32 and 1.07 to 3.48 in PL (phospholipid) and TAG fraction, respectively. The results also showed that the major components were palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1ω-9), palmitoleic acid (C16:1ω-7), docosahexaenoic acid (DHA, C22:6ω-3), arachidonic acid (AA, C20:4ω-6) and docosapentaenoic acid (C22:5ω-3) in total lipid, C16:0, C18:1ω-9, AA and DHA in PL, C16:0, C16:1ω-7, C18:1ω-9, linoleic acid (LA, C18:2ω-6), and DHA in TAG extracted from the muscle of M. mastacembelus in all seasons.

Effects of Concomitant Use of N-Acetylcysteine and Cyclosporine a on Acetaminophen-Induced Acute Kidney Injury in Mice
(Agricultural Research Communication Centre, 2024) Kocamueftueoglu, Gonca Ozan; Tektemur, Nalan Kaya; Guzel, Elif Erdem; Tektemur, Ahmet; Ozan, Ibrahim Enver
Background: Acetaminophen (APAP), a commonly used analgesic, causes acute kidney injury (AKI) in overdose although it is rare. Mitochondrial dysfunction plays a major role in the pathophysiology of renal damage, although the exact molecular mechanism is unknown. This study aimed to evaluate the potential therapeutic effect of cyclosporin A (CsA), a mitochondrial membrane permeability Methods: Male BALB/c mice were divided into Control, APAP, APAP+NAC, APAP+CsA and APAP+NAC+CsA groups (n=6). A single dose of APAP (400 mg/kg) was administered intraperitoneally. All other treatments (1200 mg/kg NAC, 50 mg/kg CsA) were performed intraperitoneally 3 h after APAP administration. All animals were decapitated and blood samples and kidney tissue samples were collected for evaluation. Serum creatinine (Cr) and blood urea nitrogen (BUN) levels were measured. The kidney tissue 8-hydroxydeoxyguanosine (8-OHdG), cytochrome c (Cytc) and 3-nitrotyrosine (3-NT) levels and cytochrome c (Cytc) expressions were determined. Result: Increased Cr and BUN levels, histopathological examinations and expressions of 8-OHdG, 3-NT and Cytc were detected in the APAP group. Combined NAC+CsA treatment sufficiently reversed oxidative stress, serum Cr and BUN levels and histopathological alterations induced by APAP. Moreover, cytc levels and renal tubular injury were remarkably reduced by combined drug treatment compared to the APAP+NAC group. These data suggest that the therapeutic effect of combined NAC+CsA treatment in mice with APAP-induced nephrotoxicity can be related to the combination of the antioxidant effect of NAC and the mitochondrial MPTP inhibitor effect of CsA.

(2022) Alhilal, M; Sulaiman, Y A M; Subuh, A M; Habra, N; Alhilal, S
The impact of oils rich in long chain monounsaturated fatty acids (LCMUFA) against hyperlipidemia and non-alcoholic fatty liver disease (NAFLD) has been inadequately described. In addition, the chemical solvents and the high temperature used in vegetable oils extraction process from seeds cause severe loss of many vital compounds. So the goal of this paper was to examine the effect of cold pressed Eruca sativa Mill seeds oil (ESSO), as a source of LCMUFA, on hyperlipidemia and NAFLD in Syrian hamster. The ESSO content of fatty acids was analyzed using chromatographic methods. Fifty two (52) healthy male golden Syrian hamsters used in this experiment were randomly divided into 4 groups (Completely Randomized Design). Negative control group, CHD group, positive control group and ESSO group. This experiment was achieved in two periods. The first period continued 4 weeks, in which hyperlipidemia and NAFLD were induced in CHD, positive control and ESSO groups through feeding on a hyperlipidemic diet. The second period also lasted 4 weeks, in which ESSO was orally gavaged at 2 g/kg of the body weight daily to animals of ESSO group. The levels of total cholesterol (TC), triglycerides, HDL-C and glucose and the activities of ALT, AST, ALP, LDH and CK were analysed in the serum. One way analysis of variance (ANOVA) followed by Duncan's multiple range test was used for statistical analysis. The consumption of hyperlipidemic diet for 4 weeks caused a significant raise (P<0.05) of triglycerides, glucose, ALT, AST, LDH, CK and a significant reduction (P<0.05) of the HDL-C/TC ratio, at the same time created lipid accumulation in liver cells in CHD, positive control and ESSO groups in comparison with negative control group at the end of the first period. These negative influences were alleviated in ESSO group by administration of ESSO at the end of second period. In conclusion, The examined cold pressed ESSO has effective hypolipidemic and hepatoprotective effects in Syrian hamsters with hyperlipidemia and NAFLD.

(Womens Health & Action Research Centre, 2024) Donmez, Ayseguel; Yesil, Yesim
The study was cross-sectional research that surveyed 410 nurses and midwives from March 2020 to March 2021 in Turkey. The aim of this study was to evaluate the knowledge and attitudes of nurses and midwives towards recognizing violence against women. The "Scale for Nurses' and Midwives' Recognition of the Symptoms of Violence against Women" were used. The average total scale score was 20.3 +/- 3.2. The score of participants who are receiving postgraduate education, working in the field of gynaecology and obstetrics, and considering intervention as a professional responsibility when encountering a woman who has experienced violence was found to be significantly higher than the other groups (p<.05). It is important for midwives and nurses to be aware of signs of violence to identify violence against women. Providing education to midwives and nurses regarding signs of violence against women will contribute to the recognition, prevention, and awareness of violence.

Experimental and theoretical investigation of pyrazinecarboxamide against mild steel corrosion
(Journal of Dispersion Science and Technology, 2021) Keleşoğlu, Ayşen; Sığırcı, Gökmen; Yıldız, Reşit; Dehri, İlyas
Pyrazinecarboxamide was examined against mild steel corrosion in 0.5 M HCl solution. The electrochemical techniques like electrochemical impedance spectroscopy, linear polarization resistance and potentiodynamic polarization measurements were carried out in the presence of various concentrations of pyrazinecarboxamide ranging from 0.25 mM to 1.0 mM. The inhibition effect of pyrazinecarboxamide on the mild steel surface was studied by atomic force microscopy and scanning electron microscopy. The adsorption of this inhibitor was determined to fit Langmuir adsorption isotherm. The adsorption/desorption equilibrium constant was calculated as 2.985 × 104 M−1, indicating that high proportion of pyrazinecarboxamide takes place on mild steel surface. The inhibition efficiency was found as 93.5% from electrochemical impedance spectroscopy measurement in an acid solution containing 1.0 mM pyrazinecarboxamide. Quantum chemical parameters that were in good agreement with experimental results were determined by density functional theory.

(International Journal of Medicinal Mushrooms, 2023) Kaya Tektemur, Nalan; Tektemur, Ahmet; Güzel, Elif Erdem
Doxorubicin (DOX), a broad spectrum chemotherapeutic, has toxic effects on healthy tissues. Mitochondrial processes and oxidative stress act in the DOX-induced toxicity, therefore antioxidant therapies are widely used. The study was aimed to evaluate the therapeutic potential of Pleurotus eryngii extract (PEE), an extract of a fungus with antioxidant properties, against DOX-induced lung damage. Rats were divided into Control, DOX, DOX + PEE, and PEE groups (n = 6). DOX was administered intraperitoneally in a single dose (10 mg/kg BW) and PE (200 mg/kg BW) was administered by oral gavage every other day for 21 days. Histopathological evaluations, immunohistochemical analyses, total oxidant status (TOS)/total antioxidant status (TAS) method, and quantitative real-time polymerase chain reaction (qRT-PCR) analysis were performed. DOX led to severe histopathological disruptions in rat lungs. Also, DOX remarkably increased the expression of dynamin 1 like (DRP1) and decreased the expression of mitofusin 1 (MFN1) and mitofusin 2 (MFN2) genes, which are related to mitochondrial dynamics. Moreover, DOX caused an increase in TOS/ TAS and 8-hydroxy-2-deoxyguanosine (8-OHdG) levels. On the other hand, PEE treatment remarkably normalized the histopathological findings, mitochondrial dynamics-related gene expressions, markers of oxidative stress, and DNA damage. The present study signs out that PEE can ameliorate the DOX-mediated lung toxicity and the antioxidant mechanism associated with mitochondrial dynamics can have a role in this potent therapeutic effect.
