ABSTRACT
Individuals employ various coping mechanisms to deal with the fear of death. While materialism and status consumption are commonly recognized in the literature as such strategies, no study has yet empirically tested this premise. Accordingly, this study examined the mediating role of death avoidance in the link between the fear of death and death-related status consumption (DRSC). Data obtained from 346 participants were analyzed using structural equation modeling. The results showed that fear of death significantly and positively influences DRSC and that death avoidance partially and positively mediates this relationship. Results also revealed that materialism strengthens the relationship between fear of death and DRSC, while it does not significantly moderate the relationship between death avoidance and DRSC. These results support the conclusion that death-related status consumption may play a critical role as an avoidance mechanism in coping with the fear of death. This study, being among the few that investigate death-related consumer behaviors, enriches both terror management theory and the literature on consumer behavior in crises.
ABSTRACT
Although the need for uniqueness has been extensively investigated by consumer researchers, food and tourism researchers have been silent on this promising research topic. This study examined food neophilia and ethnic food involvement as potential mediators of the association between tourists' need for uniqueness (TNFU) and ethnic food purchase intention. Additionally, it was tested whether independent self-construal moderates this serial mediation effect. Results showed that the relationship between tourists' need for uniqueness and ethnic food purchase intention was serially and positively mediated by food neophilia and ethnic food involvement. Furthermore, the moderated serial mediation effect was stronger at higher values of independent self-construal.
ABSTRACT
Although it has been widely discussed in the literature, no scale has yet been developed to measure the consumption aspect of death. This study aims to develop a domain-specific death-related status consumption (DRSC) scale to bridge this gap in the field. Results reveal the following three dimensions of the scale: conspicuousness, planning, and showing respect. In four studies, which collate the views of 1,302 participants, both students and adults, the DRSC demonstrates internal consistency and validity across cultures (Turkey, the U.S., and culturally diverse sample). The importance of such a scale for the field is discussed.

BACKGROUND: Anaplastic Thyroid Cancer (ATC) is one of the most lethal and aggressive human malignancies. Studies have shown that Cancer Stem-Cell (CSC) phenotype is mainly responsible for ATC aggressiveness. Cytostatic compounds are mostly ineffective because of multidrug resistance mechanisms driven by the CSC phenotype. Taxanes have limited efficacy. Recently, CSC inhibition using plant-derived, less toxic compounds, which have anti-cancer efficacy, has become a novel treatment modality. The aim of the study was to evaluate the anti-cancer activity of two natural compounds (curcumin and deguelin) on ATC cells and their CSC properties. In addition, the efficacies of these compounds were compared with that of docetaxel. METHODS: Besides control, five treatment groups were formed. ATC cells (CAL-62) were treated with curcumin, deguelin, docetaxel, and their combinations (curcumin+docetaxel, deguelin+docetaxel) at previously determined IC50 doses. Stemness was analyzed by quantitative estimation of sphere formation in matrigel, expression of several cell surface markers (CD133, CD90, Nanog, and OCT3/4) using flow cytometry, and quantification of the hypoxic status [Oxidative Stress Index (OSI) and Superoxide Dismutase (SOD) activity]. The anti-cancer efficacies of these compounds and their combinations were evaluated by determining the alterations in the cell cycle, apoptosis, and tumoral cell migration. RESULTS: Both the natural compounds (particularly curcumin) significantly suppressed the spheroid formation and cellular motility in matrigel as well as suppressed the accumulation of cells in the G0/1 phase, in which the maximum CSC activity is observed. The compounds did not suppress the expression of CSC markers, but twothirds of the cells expressed CD90. Deguelin was found to be particularly effective in inducing apoptosis similar to docetaxel at IC50 concentrations. Curcumin reduced the OSI and deguelin enhanced the SOD activity, even in docetaxel pre-treated cells. CONCLUSION: A large proportion of anaplastic tumors might consist of heterogeneous CSC population. Curcumin and deguelin have anti-cancer and several anti-stem cell activities against ATC cells. These natural compounds are capable of altering the aggressive behavior of ATC cells through the inhibition of the CSC phenotype. As a novel therapeutic target, CD90 should be investigated in other ATC cell lines and in vivo models.

PURPOSE: The purpose of this to investigate whether selective laser trabeculoplasty (SLT) has any effect on the success of trabeculectomy. PATIENTS AND METHODS: Thirteen-one eyes of 29 primary open-angle glaucoma patients who underwent SLT before trabeculectomy and 29 eyes of 27 patients with the same inclusion criteria which underwent trabeculectomy without prior SLT in the Sifa University and in the Batigöz Eye Hospital in January 2012 and November 2012 were reviewed. All patients underwent trabeculectomy for uncontrolled open-angle glaucoma with the same technique. The results were evaluated 3, 6, 12, 18, and 24 months later after surgery. The statistical analysis was performed with the Mann-Whitney U-test. Fisher's Exact Chi-square test was used to compare the continuous and categorical variables. RESULTS: The mean intraocular pressure (IOP) before surgery was 24.1 ± 1.9 in the SLT-performed group and 26.7 ± 1.6 in the non-SLT-performed group. Twenty-four months later, the mean IOP was 15.1 ± 1.2 in the SLT-performed group and 15.4 ± 1.4 in the non-SLT performed group. There was no difference in the IOP drop after trabeculectomy between the two groups (P = 0.531). CONCLUSIONS: SLT has no influence on trabeculectomy success.
ABSTRACT
BACKGROUND: Several studies evaluating the prognostic factors of gastrointestinal and pancreatic neuroendocrine tumors (GEP-NETs) have been published. The neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have been accepted as prognostic factors for cancer patients. MATERIALS AND METHODS: This study included 132 patients diagnosed with GEP-NETs. Peripheral blood samples were collected before the pretreatment period. RESULTS: NLR and PLR were increased as the grade increased in NETs. The embryonic origin analysis revealed higher NLR and PLR rates in NETs of foregut origin. NLR and PLR were also higher in pancreatic NET patients compared to the gastroenteric NET patients. Analysis of NETs by TNM indicated that an advanced stage was accompanied by significantly higher NLR and PLR. We found a strong negative correlation between progression-free survival and NLR and PLR. CONCLUSION: The study verified that NLR and PLR are simple laboratory findings that can be used to identify NETs with a worse outcome.

OBJECTIVE: The aim of this study is to investigate the effects of resveratrol in a rat model of ovarian hyperstimulation syndrome (OHSS) and compare with cabergoline. DESIGN: Randomized controlled, animal study. ANIMAL(S): Female Wistar rats. MATERIAL AND METHODS: A rat OHSS model was used to investigate the effects of resveratrol compare with cabergoline administration for preventing OHSS. Body weight, ovary weight, diameter, vascular permeability (VP), vascular endothelial growth factor (VEGF), cyclooxygenase-2 (COX-2) expression (immunohistochemistry), and serum estradiol (E2) levels were then compared. RESULTS: The ovarian VEGF concentration was significantly increased in the OHSS Groups (Groups 3-5) compared with the control groups (1 and 2). But vascular permeability, VEGF, and COX-2 expressions were reduced in animals treated with the resveratrol group compared with the cabergoline group (group 5) and the severe OHSS (group 3) group. Blood E2 levels were decreased in group treated with the resveratrol group compared with the cabergoline group (group 5) and severe the OHSS (group 3) group. CONCLUSION(S): Our results in a rat model suggest that resveratrol has a beneficial effect on OHSS by reducing the increases in ovarian daimeter, VP, and VEGF expression associated with OHSS. These effects may be mediated by the COX-2 inhibitory capacity of resveratrol.

PURPOSE: The adipose tissue plays a role in carcinogenesis with the adipokines it generates. Apelin is an anti-obesigenic adipokine, and assumes roles in both vascularization and tumor cell proliferation. The present study aimed to investigate changes in apelin levels, in postmenopausal breast cancer (BC) patients receiving aromatase inhibitors (AIs). METHODS: Forty early-stage postmenopausal BC patients treated with AIs with no history of chemotherapy administration were included in the study. At the beginning, we measured serum apelin levels in postmenopausal BC patients who were receiving AIs and healthy women of similar age and normal body mass index (BMI) (control group). We evaluated changes in the body composition, serum lipid profile and serum apelin levels at the beginning and the 12th month through anthropometric measurements and bioelectric impedance analysis. RESULTS: Forty subjects with postmenopausal BC had a median age of 57 years (range 44-82)). BC patients exhibited significantly higher apelin levels and body mass index (BMI) scores compared to the control group (p=0.0001, p=0.0001, respectively). The 12th month's measurements indicated reduced apelin levels in 24 patients (60%) and increased apelin levels in 16 patients (40%) compared to the initial figures. With respect to the parameters, the patients with reduced apelin levels had significantly different waist-to-hip ratio (WHR) and fat mass scores compared to those with higher apelin levels (p=0.008, p=0.047, respectively). CONCLUSION: This study showed that postmenopausal BC patients had high levels of apelin and high BMI scores. This finding suggests that apelin promoted carcinogenesis particularly in obese individuals. The massive and metabolic changes observed in the fat tissues of the postmenopausal BC patients receiving AIs will especially affect the BC-associated outcome.

PURPOSE: To investigate the effects of dehydration due to fasting on diurnal changes of intraocular pressure, anterior segment biometrics, and refraction. SUBJECTS AND METHODS: The intraocular pressures, anterior segment biometrics (axial length: AL; Central corneal thickness: CCT; Lens thickness: LT; Anterior chamber depth: ACD), and refractive measurements of 30 eyes of 15 fasting healthy male volunteers were recorded at 8:00 in the morning and 17:00 in the evening in the Ramadan of 2013 and two months later. The results were compared and the statistical analyses were performed using the Rstudio software version 0.98.501. The variables were investigated using visual (histograms, probability plots) and analytical methods (Kolmogorov-Smirnov/Shapiro-Wilk test) to determine whether or not they were normally distributed. RESULTS: The refractive values remained stable in the fasting as well as in the control period (p = 0.384). The axial length measured slightly shorter in the fasting period (p = 0.001). The corneal thickness presented a diurnal variation, in which the cornea measured thinner in the evening. The difference between the fasting and control period was not statistically significant (p = 0.359). The major differences were observed in the anterior chamber depth and IOP. The ACD was shallower in the evening during the fasting period, where it was deeper in the control period. The diurnal IOP difference was greater in the fasting period than the control period. Both were statistically significant (p = 0.001). The LT remained unchanged in both periods. CONCLUSIONS: The major difference was shown in the anterior chamber shallowing in the evening hours and IOP. Our study contributes the hypothesis that the posterior segment of the eye is more responsible for the axial length alterations and normovolemia has a more dominant influence on diurnal IOP changes.

OBJECTIVE: To evaluate the effects of letrozole and cabergoline in a rat model of ovarian hyperstimulation syndrome (OHSS). STUDY DESIGN: In this prospective, controlled experimental study, the 28 female Wistar rats were divided into four subgroups (one non-stimulated control and three OHSS-positive groups: placebo, letrozole, and cabergoline). To induce OHSS, rats were injected with 10 IU of pregnant mare serum gonadotropin from day 29 to day 32 of life, followed by subcutaneous injection of 30 IU hCG on day 33. Letrozole rats received with a single dose of 0.1 mg/kg letrozole via oral gavage, on the hCG day. Cabergoline rats received with a single dose of 100 µg/kg cabergoline via oral gavage, on the hCG day. All animals were compared in terms of body weight, vascular permeability (VP), ovarian diameter, ovarian tissue VEGF expression (assessed via immunohistochemical staining), and blood pigment epithelium-derived growth factor (PEDF) levels. RESULTS: The OHSS-positive placebo group (group 2) exhibited the highest VP, ovarian diameter, extent of VEGF staining, and lowest PEDF level, as expected. No significant difference was evident between the letrozole and cabergoline groups in terms of any of body weight; VP; PEDF level; ovarian diameter; or the staining intensity of, or percentage staining for, VEGF in ovarian tissues. CONCLUSIONS: Letrozole and cabergoline were equally effective to prevent OHSS, reducing the ovarian diameter, VP, and PEDF and VEGF levels to similar extents.

OBJECTIVES: To determine the efficacy of montelukast in comparison with cabergoline in the prevention of ovarian hyperstimulation syndrome (OHSS) in rats. MATERIAL AND METHODS: An experimental OHSS model was formed in 35 female Wistar rats. Rats (22 days old) were randomized into 5 groups, each containing 7 animals. The control group received no therapy; the mild OHSS group was administered pregnant mare serum gonadotropin (PMSG) 10 IU for 4 days, hCG 10 IU on the 5th day; the severe OHSS group received PMSG 10 IU for 4 days, hCG 30 IU on the 5th day The montelukast group: received montelukast 10 mg/kg/day and the cabergoline group was administered cabergollne 100 microg/kg/day via oral gavage for 6 days (days 22-27), in addition to those of severe OHSS. All groups were sacrificed on 28th day Body weight, ovarian diameter and weight, vascular permeability vascular endothelial growth factor (VEGF), semiquantitative VEGF receptor-1, and VEGF receptor-2 (VEGFR-2) immunohistochemistry were evaluated. RESULTS: Ovarian diameter and VEGF expression were significantly lower in the montelukast and cabergoline groups than in the severe OHSS group. While montelukast was more effective in limiting vascular permeability in the severe OHSS, cabergoline was superior to montelukast with respect to the limiting effect on increased body weight and VEGFR-2 expression. CONCLUSIONS: The VEGF/VEGFR-2 interaction plays an important role in OHSS pathogenesis. Montelukast limits VEGF expression, and cabergoline reduces both VEGF and VEGFR-2 expressions; they are both effective therapies for the prevention of severe OHSS.

BACKGROUND: Exposure to exogenous zinc results in increased apoptosis, growth inhibition, and altered oxidative stress in cancer cells. Previous studies also suggested that zinc sensitizes some cancer cells to cytotoxic agents depending on the p53 status. Therefore, zinc supplementation may show anticancer efficacy solely and may increase docetaxel-induced cytotoxicity in non-small-cell lung cancer cells. METHODS: Here, we report the effects of several concentrations of zinc combined with docetaxel on p53-wild-type (A549) and p53-null (H1299) cells. We evaluated cellular viability, apoptosis, and cell cycle progression as well as oxidative stress parameters, including superoxide dismutase, glutathione peroxidase, and malondialdehyde levels. RESULTS: Zinc reduced the viability of A549 cells and increased the apoptotic response in both cell lines in a dose-dependent manner. Zinc also amplified the docetaxel effects and reduced its inhibitory concentration 50 (IC50) values. The superoxide dismutase levels increased in all treatment groups; however, glutathione peroxidase was slightly increased in the combination treatments. Zinc also caused malondialdehyde elevations at 50 µM and 100 µM. CONCLUSION: Zinc has anticancer efficacy against non-small-cell lung cancer cells in the presence of functionally active p53 and enhances docetaxel efficacy in both p53-wild-type and p53-deficient cancer cells.

OBJECTIVE: The aim of this study is to evaluate the relationship between postpartum depression (PPD), infantile colic (IC) and different psychosocial variables, psychiatric symptoms, attachment style and perceived social support in expecting parents. METHOD: Two hundred forty five expecting mothers and 150 expecting fathers were first interviewed between the 22-34 weeks of pregnancy. Sociodemografic data form, Adult Attachment Style Scale (AASS), State Anxiety Inventory (SAI), Edinburgh Postnatal Depression Scale (EPDS), Multidimensional Scale of Perceived Social Support (MSPSS) and Brief Symptom Inventory (BSI) were filled out by each expecting parent. Second interview was conducted between the postpartum 4-24 weeks. Data form consisting health, nutrition, sleep and crying problems of the infant and EPDS and SAI were filled out by mothers and SAI by fathers. RESULTS: One in every four mothers had PPD symptoms above the threshold on EPDS. Maternal and paternal insecure attachment style, maternal psychiatric symptoms and postpartum anxiety level were found to be the predictors of PPD. One in every five infants had IC and maternal education level, hostility score and PPD symptoms along with paternal insecure attachment style and psychiatric symptoms were the main predictors of IC. CONCLUSION: Results about PPD and IC regarding maternal variables are consistent with the literature. In addition, paternal insecure attachment style is found to be an important risk factor for both PPD and IC. Fathers should also be included in further studies exploring PPD or IC.

PURPOSE: To evaluate the efficacy of myo-inositol (MI) pretreatment in OHSS. METHODS: In this experimental OHSS rat model, 42 immature Wistar albino female rats were divided into 6 groups: (1) the control group, (2) the ovarian stimulation group, (3) the OHSS group, (4) the OHSS + Metformin group, (5) OHSS + MI group, (6) OHSS + Metformin + MI group. OHSS was established after treatment with metformin and myo-inositol for 14 days, in the meanwhile the treatment of metformin and myo-inositol was also continued. All animals were killed 48 h after hCG administration and were compared in terms of vascular permeability, ovarian weight and diameter, ovarian VEGF, COX-2 and PEDF expression (immunohistochemistry), serum PEDF and estradiol (E2) levels. RESULTS: Vascular permeability, VEGF and COX-2 expressions were reduced in animals treated with MI and/or metformin. While PEDF expression was increased in the groups taking metformin, there was no difference in PEDF expression in the group taking MI and OHSS group. There was no significant difference in serum PEDF levels between groups. Blood E2 levels were decreased in groups treated with MI or metformin compared to the OHSS group. CONCLUSIONS: Our data demonstrate that myo-inositol is effective in preventing OHSS, similar to metformin. Although the two drugs are thought to act through distinct mechanisms, there is no apparent benefit to co-treatment with both drugs in an animal model of OHSS. Administration of myo-inositol prior to IVF treatment may favor the control of ovulation induction. Further studies are necessary to elucidate the mechanism of action and further support our findings.

OBJECTIVE: Carotid stenosis is associated with hemodynamic cerebral ischemia. Diffusion-weighted MR imaging allows for the assessment of changes related to alterations in tissue integrity. The aim of this study was to investigate (a) whether white matter lesions (WML) and apparent diffusion coefficient (ADC) values differ between ipsilateral and contralateral hemispheres, (b) whether ADC values are related to WMLs and common vascular risk factors, and (c) whether ADC values differ after carotid endarterectomy (CEA) without a shunt in patients with unilateral internal carotid artery stenosis (ICAS). METHODS: Twenty-five patients (16 men, 9 women; mean age of 68 years) with unilateral ICAS (≥ 70% carotid stenosis) were assessed with brain MRI before and after CEA, prospectively. Two experienced radiologists scored the WMLs. Bilateral ADC values in anterior and posterior periventricular WM, occipital WM, and thalamus were evaluated on preoperative and postoperative MRI. Differences in ADC values and WML scores between the two hemispheres were assessed and associations between ADC values, WML scores, and explanatory variables (e.g., age, sex, vascular risk factors) were analyzed. RESULTS: WMLs were significantly greater and ADC values were elevated in the ipsilateral cerebral WM. After CEA, ADC values rapidly decreased but remained higher than within the contralateral hemisphere. Ipsilateral hemispheric ADC values were associated with basal ganglia WMLs. No association between ADC values and vascular risk factors was found. CONCLUSION: ICAS is associated with increased diffusion in normal-appearing WM in comparison to more prominent chronic ischemic lesions. CEA has a partial effect on diffusion. These cerebral changes may be related to chronic low-grade ischemic damage that is induced by ICAS.

PURPOSE: To investigate the effect of vitamin D in ovarian hyperstimulation syndrome (OHSS). METHODS: In this animal study, 28 immature female Wistar rats were divided into four groups: group 1 (control); group 2 (ovarian stimulation); group 3 (OHSS group); group 4 (OHSS + vitamin D group). All groups were killed 48 h after hCG administration and were compared in terms of vascular permeability, ovarian weight, ovarian diameter, vascular endothelial growth factor (VEGF) expression (immunohistochemistry) in ovarian tissue and pigment epithelium-derived factor (PEDF) level in the serum (ELISA test) with the Kruskal-Wallis and Mann-Whitney U tests. RESULTS: VEGF expression in the vitamin D group was similar to that in the OHSS group. However, the PEDF level was significantly higher in the vitamin D group (p = 0.013). CONCLUSIONS: Prophylactic vitamin D supplementation is not sufficiently effective in preventing OHSS. Vitamin D effectively increases PEDF, which has an opposing effect on VEGF, which plays a key role in OHSS. Thus, the protective effect of Vitamin D on OHSS should be investigated with a vitamin D deficient model in the study group.

OBJECTIVE: The aim of the present study is to determine the potential risk factors for adenomyosis and to investigate its relationship with accompanying gynecological pathologies and clinical characteristics. MATERIALS AND METHOD: This study is a retrospective analysis of 945 patients who underwent hysterectomy between May 2005 and January 2013 at the Sifa University Medical Faculty Hospital, Clinic of Obstetrics and Gynecology. The study included 327 patients with adenomyosis and 618 patients without adenomyosis by histopathological examination of the uterus. RESULTS: There was a significant positive correlation between development of adenomyosis and presence of leiomyoma (p < 0.0001), history of previous abortion (p < 0.0001), history of previous pregnancy (p = 0.0002), and normal body mass index (p < 0.0001). However, no significant relationship existed between development of adenomyosis and smoking (p > 0.4300), normal delivery (p = 0.9600), cesarean delivery (p = 0.5705), endometrial hyperplasia (p = 0.1721), or ovarian endometriosis (p = 0.8595). CONCLUSION: Women who are multiparous have leiomyoma, a previous history of abortion, and a normal body mass index are at increased risk for development of adenomyosis. Adenomyosis might be one cause of unexplained recurrent spontaneous abortion during pregnancy.

This study aims to improve a medical module which provides a real-time medical information flow about pre-hospital processes that gives health care in disasters; transferring, storing and processing the records that are in electronic media and over internet as a part of disaster information systems. In this study which is handled within the frame of providing information flow among professionals in a disaster case, to supply the coordination of healthcare team and transferring complete information to specified people at real time, Microsoft Access database and SQL query language were used to inform database applications. System was prepared on Microsoft .Net platform using C# language. Disaster information system-medical module was designed to be used in disaster area, field hospital, nearby hospitals, temporary inhabiting areas like tent city, vehicles that are used for dispatch, and providing information flow between medical officials and data centres. For fast recording of the disaster victim data, accessing to database which was used by health care professionals was provided (or granted) among analysing process steps and creating minimal datasets. Database fields were created in the manner of giving opportunity to enter new data and search old data which is recorded before disaster. Web application which provides access such as data entry to the database and searching towards the designed interfaces according to the login credentials access level. In this study, homepage and users' interfaces which were built on database in consequence of system analyses were provided with www.afmedinfo.com web site to the user access. With this study, a recommendation was made about how to use disaster-based information systems in the field of health. Awareness has been developed about the fact that disaster information system should not be perceived only as an early warning system. Contents and the differences of the health care practices of disaster information systems were revealed. A web application was developed supplying a link between the user and the database to make date entry and data query practices by the help of the developed interfaces.
