Abstract
BACKGROUND There is no standard treatment recommended at category 1 level in international guidelines for subsequent therapy after cyclin-dependent kinase 4/6 inhibitor (CDK4/6) based therapy. We aimed to evaluate which subsequent treatment oncologists prefer in patients with disease progression under CDKi. In addition, we aimed to show the effectiveness of systemic treatments after CDKi and whether there is a survival difference between hormonal treatments (monotherapy vs. mTOR-based). METHODS A total of 609 patients from 53 centers were included in the study. Progression-free-survivals (PFS) of subsequent treatments (chemotherapy (CT, n:434) or endocrine therapy (ET, n:175)) after CDKi were calculated. Patients were evaluated in three groups as those who received CDKi in first-line (group A, n:202), second-line (group B, n: 153) and ≥ 3rd-line (group C, n: 254). PFS was compared according to the use of ET and CT. In addition, ET was compared as monotherapy versus everolimus-based combination therapy. RESULTS The median duration of CDKi in the ET arms of Group A, B, and C was 17.0, 11.0, and 8.5 months in respectively; it was 9.0, 7.0, and 5.0 months in the CT arm. Median PFS after CDKi was 9.5 (5.0-14.0) months in the ET arm of group A, and 5.3 (3.9-6.8) months in the CT arm (p = 0.073). It was 6.7 (5.8-7.7) months in the ET arm of group B, and 5.7 (4.6-6.7) months in the CT arm (p = 0.311). It was 5.3 (2.5-8.0) months in the ET arm of group C and 4.0 (3.5-4.6) months in the CT arm (p = 0.434). Patients who received ET after CDKi were compared as those who received everolimus-based combination therapy versus those who received monotherapy ET: the median PFS in group A, B, and C was 11.0 vs. 5.9 (p = 0.047), 6.7 vs. 5.0 (p = 0.164), 6.7 vs. 3.9 (p = 0.763) months. CONCLUSION Physicians preferred CT rather than ET in patients with early progression under CDKi. It has been shown that subsequent ET after CDKi can be as effective as CT. It was also observed that better PFS could be achieved with the subsequent everolimus-based treatments after first-line CDKi compared to monotherapy ET.

Abstract
OBJECTIVE Carbon tetrachloride (CCl4) is a non-polar molecule used in industry in grain curing, insect-killing and especially in the production of chlorofluorocarbons. It is estimated that an average of 70,000 industry workers in Europe are exposed to this toxic compound. MATERIALS AND METHODS Twenty-four male Sprague-Dawley rats were randomly allocated into four groups: control group (saline only, Group I), infliximab (INF) group (Group II), CCl4 group (Group III) and CCl4+INF group (Group IV). RESULTS While there was an increase in the numerical density of CD3, CD68, and CD200R positive T lymphocytes and macrophages in the CCl4 administration group (p=0.000), this was not the case in the CCl4+INF administration group (p=0.000). CONCLUSIONS TNF-α inhibitors have a protective effect against CCl4-induced spleen toxicity/inflammation as seen by the reduction in CD3, CD68, CD200R positive T lymphocytes and macrophages.

Abstract
OBJECTIVES We aimed to determine if superb microvascular imaging (SMI) can predict response to uterine artery embolization (UAE) as compared with power Doppler ultrasound. METHODS The blood flow and the volume of the dominant leiomyoma was evaluated by power Doppler ultrasonography (PDUS) and SMI 1 day before and 3 months after the UAE procedure. SMI and PDUS blood flow were classified to 4 grades of vascularity. The change in fibroid volume in Grades 0-2 (hypovascular group) was compared to the hypervascular Grade 3 group. RESULTS Twenty-eight women (mean age, 40.9 years; range, 33-53 years) were examined with PDUS and SMI before and 3 months after UAE. The volume reduction was statistically significantly higher hypervascular group (P < .05). When we accept 30% or more volume reduction as a good response to UAE, the positive predictive value, negative predictive value, sensitivity, specificity, and accuracy of SMI were 100, 64, 73.6, 100, and 82.1%, respectively. There was excellent agreement between the two blinded observers in SMI measurements. CONCLUSIONS SMI, with its high reproducibility, provides further microvessel information than PDUS in uterine fibroids. It may be a useful tool in prediction of response to UAE treatment and improve counseling and patient selection for UAE versus medical or surgical treatment options.

Abstract
OBJECTIVE Irritable bowel syndrome (IBS) is a frequently seen functional bowel disease. Although not lifethreatening, it impairs quality of life and leads to economic losses. IBS symptoms are widespread in dialysis patients. Psychopathological disorders are known to increase in both IBS and dialysis patients. The purpose of this study was to investigate the prevalence of IBS, IBS-related factors, and psychopathological disorders in patients. MATERIALS AND METHODS One hundred fifty patients followed-up in hemodialysis (HD) or peritoneal dialysis (PD) programs were included in this prospective study. Patients were divided into groups with and without diagnoses of IBS based on the Rome-III diagnostic criteria. The Symptom Check List Revised (SCL90-R) test was then applied to the patients. Patients with and without IBS were compared according to the scores obtained from the questionnaire. RESULTS IBS was determined in 59 (39.3%) of the dialysis patients. The prevalence of IBS was significantly higher in women (P = .030). The presence of coronary artery disease (CAD) and use of erythropoietin (EPO) were significantly higher in patients with IBS (P = .029, P = .031). Somatization, obsessive-compulsive disorder, interpersonal sensitivity, depression, anxiety, phobic anxiety, psychoticism, and additional items were also higher in patients with IBS. Subscale scores for somatization, depression, and additional parameters in dialysis patients with IBS were above the threshold values for screening. CONCLUSION IBS is common in dialysis patients. The presence of CAD or use of EPO were frequently observed in dialysis patients with IBS, and psychopathologies in depression, somatization, and additional subparameters were also higher in these patients.

Abstract
The aim of the current research was to investigate the prognostic significance of pretreatment hemoglobin-to-red cell distribution width ratio (HRR) in patients with renal cell carcinoma (RCC). The neutrophil-to-lymphocyte ratio, systemic immune-inflammation index, lymphocyte-to-monocyte ratio (LMR) and HRR were analyzed retrospectively to assess their prognostic value using Kaplan-Meier curves and Cox regression analysis in 198 patients with RCC. High HRR (0.72) and high LMR (2.43) were found to be associated with longer progression-free survival and overall survival. A multivariate analysis identified International Metastatic Renal Cell Carcinoma Database Consortium prognostic score, tumor stage, node stage, LMR and HRR as independent prognostic factors for progression-free survival, as well as International Metastatic Renal Cell Carcinoma Database Consortium score, neutrophil-to-lymphocyte ratio and HRR for overall survival. HRR is a an independent prognostic parameter predicting the progression and survival of patients with RCC.

Abstract
PURPOSE The Controlling Nutritional Status (CONUT) Score, a new parameter that reflects the immuno-nutritional status, has been closely associated with prognosis in many cancer types. However, the prognostic significance of the CONUT score in Glioblastoma Multiforme (GBM) is not known. In this study, we aimed to show the prognostic significance of the CONUT score in the postoperative period in patients with GBM. METHODS 120 patients followed up with GBM were included in the study, retrospectively. According to the receiver operating characteristic (ROC) curve analysis, the optimal cut-off values were determined for the CONUT score, and the patients were divided into low (<2.5) and high (≥2.5) CONUT groups. Systemic immune inflammation index (SII), prognostic nutritional index (PNI), and neutrophil-lymphocyte ratio (NLR) were grouped according to the cut-off point of 1111, 46.5, and 4.48, respectively. Cox regression analyzes were used to assess their prognostic significance for progression-free survival (PFS) and overall survival (OS). RESULTS The high CONUT score group was found to have worse PFS and OS than the low CONUT score group (p < 0.001, p < 0.001). In univariate analysis, age, gender, comorbidity, CONUT score, SII, PNI, NLR were found to be significant for both PFS and OS. In multivariate analysis, only age and CONUT score were found as independent prognostic factors for both PFS (p: 0.040, p < 0,001) and OS (p: 0,041, p < 0,001). CONCLUSION The CONUT score in the postoperative period in patients with GBM is an independent prognostic parameter that predicts progression and survival.

Abstract
PURPOSE The immuno-nutritional status is closely related to the prognosis in many cancers. Controlling nutritional status (CONUT) score is a new parameter that reflects the immuno-nutritional status and is prognostic in some cancers. However, the prognostic significance of the CONUT score in small cell lung cancer (SCLC) is unknown. We aimed to demonstrate the prognostic significance of the CONUT score in patients with SCLC. METHODS Two hundred sixteen patients who were followed up with SCLC were included in the study retrospectively. According to the receiver operating characteristic (ROC) curve analysis, the optimal cutoff values were determined for the CONUT score, and the patients were divided into low (< 2) and high (≥ 2) CONUT groups. Neutrophil-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), and prognostic nutritional index (PNI) were grouped based on a cutoff point 2.84, 626, and 46.1, respectively. Cox regression analyses were used to assess their prognostic values for progression-free survival (PFS) and overall survival (OS). RESULTS The high CONUT group had significantly worse PFS and OS than the low CONUT group (p < 0.001, p < 0.001). In univariate analysis, stage, prophylactic cranial irradiation, extrapulmonary lesion, PNI, body mass index, CONUT score were found to be significant for both PFS and OS. In multivariate analysis, only CONUT score and stage were found as independent prognostic factors for both PFS (p: 0.018, p: 0.046) and OS (p: 0.038, p: 0.006). CONCLUSION The CONUT score at the time of diagnosis is an independent prognostic parameter that predicts recurrence and survival times in SCLC.

Abstract
The diversity of forest trees as an indicator of ecosystem health can be assessed using the spectral characteristics of plant communities through remote sensing data. The objectives of this study were to investigate alpha and beta tree diversity using Landsat data for six dates in the Gönen dam watershed of Turkey. We used richness and the Shannon and Simpson diversity indices to calculate tree alpha diversity. We also represented the relationship between beta diversity and remotely sensed data using species composition similarity and spectral distance similarity of sampling plots via quantile regression. A total of 99 sampling units, each 20 m × 20 m, were selected using geographically stratified random sampling method. Within each plot, the tree species were identified, and all of the trees with a diameter at breast height (dbh) larger than 7 cm were measured. Presence/absence and abundance data (tree species number and tree species basal area) of tree species were used to determine the relationship between richness and the Shannon and Simpson diversity indices, which were computed with ground field data, and spectral variables derived (2 × 2 pixels and 3 × 3 pixels) from Landsat 8 OLI data. The Shannon-Weiner index had the highest correlation. For all six dates, NDVI (normalized difference vegetation index) was the spectral variable most strongly correlated with the Shannon index and the tree diversity variables. The Ratio of green to red (VI) was the spectral variable least correlated with the tree diversity variables and the Shannon basal area. In both beta diversity curves, the slope of the OLS regression was low, while in the upper quantile, it was approximately twice the lower quantiles. The Jaccard index is closed to one with little difference in both two beta diversity approaches. This result is due to increasing the similarity between the sampling plots when they are located close to each other. The intercept differences between two investigated beta diversity were strongly related to the development stage of a number of sampling plots in the tree species basal area method. To obtain beta diversity, the tree basal area method indicates better result than the tree species number method at representing similarity of regions which are located close together. In conclusion, NDVI is helpful for estimating the alpha diversity of trees over large areas when the vegetation is at the maximum growing season. Beta diversity could be obtained with the spectral heterogeneity of Landsat data. Future tree diversity studies using remote sensing data should select data sets when vegetation is at the maximum growing season. Also, forest tree diversity investigations can be identified by using higher-resolution remote sensing data such as ESA Sentinel 2 data which is freely available since June 2015.

Abstract
New tetraarylazadipyrromethene metal complexes with four coordinate metals (cobalt(ii), nickel(ii), copper(ii) and zinc(ii)) and with three moieties (4-methylphenyl,4-methoxyphenyl and 1-naphthyl) were designed and synthesized targeting applications utilizing two photon absorption. The effects of metals with filled or unfilled d orbitals and substituents with various electron donor properties on the charge transfer mechanism and two photon absorption properties of tetraarylazadipyrromethene compounds were investigated by ultrafast pump-probe spectroscopy and open aperture Z-scan experiments as well as density functional theory (DFT) calculations. Ultrafast transient absorption spectra provide evidence of an efficient photoinduced intramolecular charge transfer between the ligand and metals which is independent of filled or unfilled d orbitals of metals. Although zinc has filled d orbitals, its complexes possess an absorption maximum including a shoulder which is attributed to partial ligand to metal L(π) → M(d*) charge transfer character (LMCT). Due to the charge transfer mechanism, metal complexes of tetraarylazadipyrromethene compounds exhibited two photon absorption properties in the femtosecond regime at 800 nm wavelength. The greatest two photon absorption cross section value was measured as 2690 GM for Zn(L(2))2 and 2374 GM for Co(L(3))2 complexes.

Abstract
OBJECTIVE Acromegaly is associated with increased cardiovascular morbidity and mortality. The data about the evaluation of coagulation and fibrinolysis in acromegalic patients are very limited and to our knowledge, platelet function analysis has never been investigated. So, we aimed to investigate the levels of protein C, protein S, fibrinogen, antithrombin 3 and platelet function analysis in patients with acromegaly. METHODS Thirty-nine patients with active acromegaly and 35 healthy subjects were included in the study. Plasma glucose and lipid profile, fibrinogen levels, GH and IGF-1 levels and protein C, protein S and antithrombin III activities were measured in all study subjects. Also, platelet function analysis was evaluated with collagen/ADP and collagen-epinephrine-closure times. RESULTS Demographic characteristics of the patient and the control were similar. As expected, fasting blood glucose levels and serum GH and IGF-1 levels were significantly higher in the patient group compared with the control group (pglc: 0.002, pGH: 0.006, pIGF-1: 0.001, respectively). But lipid parameters were similar between the two groups. While serum fibrinogen and antithrombin III levels were found to be significantly higher in acromegaly group (p fibrinogen: 0.005 and pantithrombin III: 0.001), protein S and protein C activity values were significantly lower in the patient group (p protein S: 0.001, p protein C: 0.001). Also significantly enhanced platelet function (measured by collagen/ADP- and collagen/epinephrine-closure times) was demonstrated in acromegaly (p col-ADP: 0.002, p col-epinephrine: 0.002). The results did not change, when we excluded six patients with type 2 diabetes in the acromegaly group. There was a negative correlation between serum GH levels and protein S (r: -0.25, p: 0.04)) and protein C (r: -0.26, p: 0.04) values. Likewise, there was a negative correlation between IGF-1 levels and protein C values (r: -0.39, p: 0.002), protein S values (r: -0.39, p: 0.001), collagen/ADP-closure times (r: -0.28, p: 0.02) and collagen/epinephrine-closure times (r:-0.26, p: 0.04). Also, we observed a positive correlation between IGF-1 levels and fibrinogen levels (r: 0.31, p: 0.01). CONCLUSION Acromegaly was found to be associated with increased tendency to coagulation and enhanced platelet activity. This hypercoagulable state might increase the risk for cardiovascular and cerebrovascular events in acromegaly.

Abstract
We present a high-throughput and inexpensive fabrication approach that uses self-assembled block copolymer (BCP) films as templates to generate dense nanoscale chemical patterns of polymer brushes for the selective immobilization of Au nanoparticles (NPs). A cross-linked random copolymer mat that contains styrene and methyl methacrylate units serves both as a base layer for perpendicular assembly of nanoscale domains of poly(styrene-block-methyl methacrylate) (PS-b-PMMA) films and as a nonadsorbing background layer that surrounds the chemical patterns. The selective removal of the PMMA block and the underlying mat via oxygen plasma etching generates binding sites which are then functionalized with poly(2-vinylpyridine) (P2VP) brushes. Au NPs with a diameter of 13 nm selectively immobilize on the patterned P2VP brushes. An essential aspect in fabricating high quality chemical patterns is the superior behavior of methyl methacrylate containing cross-linked mats in retaining their chemistry during the grafting of P2VP brushes. The use of BCPs with different molecular weights and volume fractions allows for preparation of chemical patterns with different geometries, sizes, and pitches for generating arrays of single particles that hold great promise for applications that range from molecular sensing to optical devices.

Abstract
We aimed to validate a severity grading score (SGS) system for predicting the course of disease and fatality in Crimean-Congo hemorrhagic fever (CCHF). This SGS was established using several variables that were assumed to be associated with mortality and had clinical importance. We included patients diagnosed with CCHF from different centers. Patients who had symptoms of CCHF for <5 days were included. The patients were grouped into three categories according to mortality risk. An SGS ≤4 showed no association with mortality [n = 323 (79.9 % of the total study population), and all survived]. An SGS between 5 and 8 points was classified into the intermediate risk group (20 %), and 14 of 70 patients in this group died. An SGS ≥9 was classified as the high risk of mortality group and 11 of 11 patients in this group died (p = 0.001). The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for an SGS >9 points at admission were 96, 100, 97, 100, and 44 %, respectively. This SGS system may help appropriate the triage of patients, decrease the cost of treatment, and improve the functionality of healthcare staff. The present study is the first investigation about the validation of an SGS system in patients with CCHF.

Abstract
The aim of this study was to evaluate clinical and radiographic results of submerged and non-submerged implants for posterior single-tooth replacements and to assess patient-based outcomes. Twenty patients were included in the study. A split-mouth design was used; implants inserted using a submerged technique were compared to those inserted with a non-submerged technique. Implants were restored with metal-ceramic crowns after 3 months. Reconstructions were examined at baseline, 6, 12, and 24 months. Standardized radiographs were made. Radiographic crestal bone level changes were calculated, as well as soft tissue parameters, including pocket probing depth, bleeding on probing, plaque index, and gingival index. Results were analyzed by two-way repeated measures of variance (ANOVA). To evaluate patient-based outcomes, patients were asked to complete a questionnaire at the 6-month follow-up; the Wilcoxon paired signed rank test was used to compare scores. The data of 18 patients were reviewed. During 24 months, non-submerged implants (0.57 ± 0.21 mm) showed significantly lower bone loss than submerged implants (0.68 ± 0.22 mm) (P<0.01). Patient satisfaction with non-submerged implants (median 87.5) was significantly higher than with submerged implants (median 81.5) (P<0.01). Non-submerged implants showed comparable clinical results to submerged implants and resulted in higher patient satisfaction due to decreased surgical intervention.

Abstract
Vitamin D is mainly known for its traditional role in the bone mineralization and calcium homeostasis. Recent studies have shown that vitamin D receptors (VDR) are present in almost all the tissues and cells in the human body. In addition, several studies have revealed that vitamin D is important in immunomodulation, regulation of inflammation and cytokines, cell proliferation, cell differentiation, apoptosis, angiogenesis, muscle strength, and muscle contraction. Patients with sepsis have high mortality rate and high deficiency in vitamin D. In addition, septic patients have decreased vitamin D binding-protein (DBP) levels which further exacerbate the vitamin D deficiency. The role of vitamin D treatment in sepsis syndrome has been evaluated in animal model of sepsis where 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] administration was associated with improved blood coagulation parameters in sepsis associated with a disseminated intravascular coagulation. Vitamin D treatment in vitro has also been demonstrated to modulate levels of the systemic inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6), as well as inhibit the lipopolysaccharide (LPS)-induced activation and vasodilation of vascular endothelium. Vitamin D may enhance the induction of the antimicrobial peptides, cathelicidin and b-defensin, which have been described on mucosal and epithelial surfaces acting as the body's first line of defense against viral and bacterial pathogens. Vitamin D supplementation may divert attention from relatively simple, natural, and low-costmethods of preventing severe sepsis and septic shock. Further prospective, randomized and controlled clinical trials of adjunctive vitamin D therapy in patients who are vitamin D deficient are needed in the management of human sepsis syndrome.

Abstract
In this retrospective study, we aimed to evaluate the relationship between erectile dysfunction (ED) and chronic lead intoxication (CLI) as well as the role of depression in this relationship. We compared the findings of 26 male patients with CLI and 24 male patients as the control group between November 2008 and January 2009. The blood lead levels and smoking index of patients were evaluated for both groups. The International Index of Erectile Dysfunction-erectile function domain (EFD) and Beck Depression Inventory (BDI) were obtained and reviewed in both groups. The mean blood lead levels of patients in the CLI and control groups were 42.1 and 3.2 μg dl(-1) respectively (P < 0.01). The mean interval of lead exposure of patients in CLI group was 71.5 (6-360) months. EFD scores of patients in CLI group were significantly lower, and number of patients with ED in CLI group was statistically higher (P < 0.05). BDI scores of patients in CLI group were significantly higher (P < 0.05). We detected a mildly negative and statistically significant relationship between the EFD scores and blood lead levels (r = -0.453 and P < 0.05). Our results showed that the increased frequency of ED is an independent factor in CLI group.
