Abstract
OBJECTIVE Prostate cancer (PCa) is the second most common solid tumor in men and the fifth leading cause of cancer-related death. In advanced stage, palliative treatments are used instead of curative therapies. Therefore, finding predictive indicators seems crucial. Patients with castration-resistant prostate cancer (CRPC) that received Dx chemotherapy have been retrospectively reviewed. The aim of this study was to investigate whether docetaxel (Dx)-free interval could have a predictive value for PCa and influence other sequential therapies. MATERIAL AND METHODS This clinical trial study was performed on 104 patients at Medeniyet University Oncology Clinic in 2018-2020. All CRPC patients had metastases, received Dx as first-line treatment and underwent androgen receptor axis targeted (ARAT) therapy after disease progression. We analyzed patients' progression time after Dx therapy and the effects on sequential treatment. RESULTS After Dx therapy, all patients received ARAT (abiraterone (ABI) n: 49 (47.1%) and enzalutamide (ENZ) n: 54 (51.9%)) as a second-line treatment, except for one patient who received cabazitaxel. There was a statistically significant relationship between the Dx-free interval and duration of response to ARAT (p<0.001). The response time of ARAT treatment was <10.5 months in all patients whose Dx-free interval period was <9 months. CONCLUSIONS Our findings support the theory that Dx-free interval can be a predictive factor for CRPC. CRPC disease can be classified as Dx-sensitive disease or Dx-resistance disease, based on the Dx-free interval. Decision on subsequent treatments could be made considering this information.

Abstract
OBJECTIVE Smoking cessation is affected by multiple factors including cognitive status of the patients. In this study, we aimed to investigate the effects of demographic, emotional and cognitive functions of 39 male and 42 female patients who applied to the smoking cessation outpatient clinic on smoking cessation. PATIENTS AND METHODS This study recruited 81 healthy volunteers of equal age, gender, and educational level. Total Montreal Cognitive Assessment (MoCA) scores were compared according to age, gender, cessation methods, and Beck Depression Inventory and Beck Anxiety Inventory (BAI) scores in smoking cessation settings. RESULTS In our study, there were 39 (48.1%) male patients and 42 (51.9%) female patients. While 36 patients were able to quit smoking, the remaining 38 were unable to do so. During follow-up, 7 patients had yet to be reached. Age, years of smoking, number of cigarettes smoked per day, education level, first reason for starting smoking, reasons for quitting smoking, quitting method, and medical drugs used were found to have no effect on smoking cessation; however, the MoCA total score, Beck depression scale, Beck anxiety scale, and smoking cessation scale score were found to have significant effects on smoking cessation. CONCLUSIONS Various cognitive processes, particularly visuospatial and attention skills, have been found to be useful in quitting smoking. Furthermore, emotional states, such as depression and anxiety have a negative impact on quitting smoking. We believe that if it is provided to the patients in the smoking cessation outpatient clinic to boost cognitive capabilities and treat mood problems, the success of smoking cessation will increase.

Abstract
OBJECTIVE Differentiation between renal oncocytoma (RON) and chromophobe renal cell carcinoma (chRCC) remains challenging. We aimed to assess the accurate apparent diffusion coefficient (ADC) radiomics features in differentiating these tumors. MATERIALS AND METHODS This single-center retrospective study included 14 patients with histopathologically proven RON (n = 6) and chRCC (n = 8) who underwent magnetic resonance imaging. Features were extracted from ADC maps. Features with an intraclass correlation coefficient >0.90, an intergroup p < 0.01 and interrater differences with normal distribution underwent agreement and receiver operating characteristic curve analyses. RESULTS Overall, 6 features qualified for further analysis and Bland-Altman plots revealed acceptable agreement for all. Only 1 first order feature and 5 high order texture features successfully predicted RON with more than 90% sensitivities and specificities more than 80%. CONCLUSION Squared mean ADC and certain gray level run length matrix features extracted by radiomics of ADC mapping provide quite high diagnostic precision in terms of distinguishing between RON and chRCC.

Abstract
In laying hens, a diet supplemented with tryptophan (Trp) has been shown to affect their pecking behavior. However, unlike this positive effect, Trp is also involved in negative effects on behavior and stress through indolic pathways. Indole production can be reduced by probiotics (Pro), thus we hypothesized that Pro may prevent negative effects of Trp and increase beneficial effects on behavior in birds. Combined effects of Pro and Trp were also expected. To investigate the effects on behavior in birds of supplementing with a high level of Trp with or without Pro, Japanese quail were used because their behavior can be influenced by Pediococcus acidilactici, and they can be highly aggressive. Quails (n = 120) were assigned to 4 groups in a 2 × 2 factorial design for 55 d: C-C (control diet with usual Trp level, 0.3%; without Pro; n = 30), Trp-C (Trp: 2%; without Pro; n = 30), C-Pro (control diet; with Pro: 1 x 109 CFU/L P. acidilactici in drinking water; n = 30), and Trp-Pro (Trp 2%; with Pro; n = 30). Body weight was measured every week, and different tests were conducted to investigate behavioral characteristics of each quail. Contrary to our hypothesis, there was almost no interaction between Trp and Pro treatments. Tryptophan supplementation significantly (P < 0.05) reduced live weight up to 27 d, whereas Pro treatment had no effect. There was no significant difference between groups for tonic immobility variables (P > 0.05). The birds fed the high Trp diet spent significantly less time in the periphery of the open field than those fed the control diet and moved less in the arena during the social isolation test. Interindividual distances were significantly lower in males fed with Trp 2% than with the control diet, whereas Trp and Pro supplements interacted in females. The treatments did not affect sexual motivation in males. These results indicate that a high level of Trp reduced growth and appeared to enhance emotional reactivity in quails and that supplementing with Pro did not reduce these effects. In conclusion, feeding high Trp for 55 d cannot be recommended as a strategy to improve social behavior unlike effects observed in laying hens.

Abstract
The aim of the present work was to evaluate the effect of rosemary extract (Rosmarinus Officinalis L.) on the 3-MCPD and glycidyl ester contents during deep-fat frying. Firstly, the potato samples were soaked in different concentrations of NaCl and they were fried in sunflower oils containing different concentrations of rosemary extract. Subsequently, repeated frying was carried out with sunflower oil enriched with rosemary extract. The frying oil and the oil extracted from potato samples were analyzed in terms of the contents of 3-MCPD and glycidyl esters according to DGF C VI 18 (10) method. The results demonstrated that the content of 3-MCPD and glycidyl esters in frying oil was not significantly affected by different NaCl and rosemary extract concentrations during short term frying; however, the amount of 3-MCPD esters was found to be lower for the potato crisps enriched with rosemary extract during repeated frying cycles.

Abstract
The objective of the current study was to assess the influence of a modified crushing process and kneading operation on the quality parameters, volatile compounds, and the fatty acid and sterol profiles of virgin olive oil from the Edremit yaglik variety. In the study, olive oil samples were produced in two different processes. The first one was produced without malaxation and the second one was produced with the malaxing process. During crushing, the effect of different temperatures was tested. The results demonstrate that different crushing temperatures generally did not affect the amount of free fatty acids, or peroxide value. Total phenol contents were positively affected by the additional malaxation process. Fatty acids and sterol composition were not significantly altered at different crushing temperatures or during the subsequent malaxation application. PCA enabled a clear classification of the oils obtained from different processing techniques.

Abstract
AIM We aimed to investigate the effectivity of the 0.0625 mg dose of bevacizumab in patients with retinopathy of prematurity (ROP) and compare the results with 0.625 mg dose of intravitreal bevacizumab (IVB) injection. METHODS The medical records of the patients with type 1 ROP who received IVB monotherapy were retrospectively reviewed. Demographic and clinical characteristics of the patients were recorded. The patients were classified into two groups with respect to received dose of bevacizumab as follows: group F (n = 46) (full dose of bevacizumab-0.625 mg/0.025 ml) and group L (n = 45) (low dose (one tenth) of bevacizumab-0.0625 mg/0.025 ml). RESULTS Both treatment dose regimens have similar outcomes. Moreover, the mean retinal vascularization time seemed to be significantly higher in group F compared to group L, 168 ± 65 and 97 ± 29 days, respectively (p < 0.001). Disappearance of plus sign is observed earlier in group F (2.45 ± 1.7 vs 3.66 ± 2.46 days, respectively, p = 0.03). CONCLUSIONS The low dose (0.0625 mg) of IVB treatment was effective as full (0.625 mg) dose in ROP treatment. Moreover, our results showed that low-dose treatment might provide faster retinal vascularization than the regular used dose. On the other hand, disappearance of the plus sign takes longer time in patients treated with low dose compared to eyes treated with full dose of IVB that should be taken into account.

Abstract
BACKGROUND The subarachnoid space (SAS) and ventricular width (VW) in normal infants and children were studied with ultrasonography to provide the objective measurement and define a normal range for these measurements. The additional aim was to determine the stable ratio as a SAS/VW. MATERIALS AND METHODS A total of 100 healthy subjects, including 48 males and 52 females, were studied. The cases were divided into 3 age groups: 0-6 months(n = 65), 7-12 months (n = 24) and > 13 months (n = 11). Transfontanel ultrasonography was performed in all the cases. SAS, VW and the SAS/VW ratios were calculated. The study was approved by the ethical committee. All parents were informed about the sonographic examination and their approvals were taken. RESULTS SAS was calculated as 3.1 (0.5-6) mm and VW was calculated as 3.6(1.3-5) mm. SAS/VW ratio was 0.9 ± 0.3. There was no statistically significant difference among SAS, VW and SAS/VW ratios in 3-97 percentile group (p > 0.05). CONCLUSIONS Ultrasonography can be used as a practicable and reproducible modality in the measurement of SAS and VW in healthy children. It is a non-invasive method and allows for serial follow-up. SAS/VW ratio can be used as an index in healthy children.

Abstract
OBJECTIVE A high N-terminal pro-brain natriuretic peptide (NT-proBNP) level provides significant prognostic information on patients with coronary artery disease (CAD). It is unclear whether aortic distensibility (AD), which reflects the aortic stiffness, and the extent and complexity of CAD, assessed with the SYNTAX score (SS), affect the secretion of NT-proBNP in stable CAD. We aimed to investigate the relationship between NT-proBNP levels and AD as well as with the extent and complexity of CAD in stable CAD patients. METHODS The study included 411 patients with stable CAD (mean age = 61.7 ± 9.9 years, male/female = 247/164). The patients were divided into two groups according to the median NT-proBNP value (NT-proBNPlow group < 114 pg/ml and NT-proBNPhigh group ≥ 114 pg/ml). AD was calculated from the echocardiographically derived ascending aorta diameters and hemodynamic pressure measurements. Coronary angiography was performed and SS was determined in all patients. NT-proBNP and other biochemical markers were measured in all subjects. RESULTS The AD and ejection fraction values of the NT-proBNPhigh group were lower and their SS levels were higher compared with those from the NT-proBNPlow group (p < 0.05, for all). The NT-proBNP level was independently associated with AD (β = -0.378, p < 0.001), SS (β = 0.262, p < 0.001), and ejection fraction (β = - 0.295, p < 0.001) on multiple linear regression analysis. CONCLUSION NT-proBNP was independently associated with an impaired elastic property of the aorta and with the extent and complexity of CAD as well as with left ventricular systolic dysfunction.
