Abstract
PURPOSE Pterygium is a common ocular surface disease defined by fibrovascular conjunctival growth extending onto the cornea. However, its pathogenesis remains unclear. This study aimed to determine the role of CD44, proliferating cell nuclear antigen (PCNA), and E-cadherin in pterygium formation and recurrence. METHODS Sixty patients with pterygium participated in the study, and we collected conjunctival samples from 30 patients to form a control group. CD44, PCNA, and E-cadherin expressions in surgically excised pterygium were compared with tissue samples from the control group. RESULTS We observed that the percentages of CD44 and PCNA were statistically higher in the primary pterygium group and recurrent pterygium group than in the control group (P < 0.001 and P < 0.001, respectively). Conversely, E-cadherin values were statistically higher in the control group than in the primary and recurrent pterygium groups (P = 0.013 and P < 0.001, respectively). CONCLUSION Cell proliferation and cell adhesion factors may play important roles in the pathogenesis of pterygium.

Abstract
OBJECTIVE Fetal vascular malperfusion is associated with poor perinatal outcomes in women with preeclampsia and gestational diabetes mellitus. The aim of this study was to determine the association between fetal vascular malperfusion score and syncytiotrophoblast basement membrane thickness and clinicopathological variables, such as developing preeclampsia in women with gestational diabetes mellitus. METHODS This retrospective cohort study included 65 pregnant participants (34 with gestational diabetes mellitus and 31 controls) between January 2019 and January 2022. Gestational diabetes mellitus was diagnosed as ≥2 of 4 elevated values on a 3-h, 100-g oral glucose tolerance test. The fetal vascular malperfusion score was evaluated by endothelial CD34 positivity in the villous stroma of the placenta. The association between fetal vascular malperfusion score and syncytiotrophoblast basement membrane thickness with clinicopathological variables in women with gestational diabetes mellitus was evaluated. RESULTS It was revealed that the gestational diabetes mellitus group had greater fetal vascular malperfusion scores than the control group (gestational diabetes mellitus group fetal vascular malperfusion score: 34.2±9.1 and control group fetal vascular malperfusion score: 26.5±8.7, respectively, p=0.0009). Syncytiotrophoblast basement membrane thickness was correlated with the development of preeclampsia, trophoblast proliferation, and fetal vascular malperfusions (0.3952, p=0.0129; 0.3487, p=0.0211; and 0.4331, p=0.0082, respectively). On the contrary, fetal vascular malperfusions were correlated with the development of preeclampsia, villous edema, and trophoblast proliferation (0.3154, p=0.0343; 0.2922, p=0.4123; and 0.3142, p=0.0355, respectively). CONCLUSION The gestational diabetes mellitus group displayed significantly higher fetal vascular malperfusion scores and thickening of the syncytiotrophoblast basement membrane than the control group. There is a correlation between developing preeclampsia and the fetal vascular malperfusion scores and the syncytiotrophoblast basement membrane thickness.

Abstract
OBJECTIVE The current study aimed to delineate the relationship between furin and chronic inflammation while cervical intraepithelial neoplasia progresses to cancer. STUDY DESIGN This cross-sectional study included 81 women who required colposcopic examinations. The study groups were formed based on pathological results: Group I included women with cervical intraepithelial neoplasia (CIN) I (n = 30); Group II included women with CIN II-III (n = 28); and Group III included women with cervical cancer (CC) (n = 23). Furin, ki-67, and p16 levels were evaluated based on immunostaining intensity. The inflammatory indices were calculated in parallel with the literature from routine blood samples retrieved within one week before the procedure. RESULTS Furin expression gradually increased from CIN I to CIN II-III and from CIN II-III to CC, respectively (p < 0.001, p = 0.005). NLR, MLR, PLR, and SII were significantly higher in the CC group (p < 0.001). ROC curve analysis unveiled that NLR, MLR, PLR, and SII predicted the presence of CC with a cutoff value of 2.39 for NLR (sensitivity: 91.3%, specificity: 63.8%, AUROC: 0.79, p < 0.001); a cutoff value of 0.27 for MLR (sensitivity: 78.3%, specificity: 72.4%, AUROC: 0.77, p = 0.009); a cutoff value of 123 for PLR (sensitivity: 100%, specificity: 41.4%, AUROC: 0.70, p = 0.04); and a cutoff value of 747 for SII (sensitivity: 69.6%, specificity: 90.7%, AUROC: 0.71, p = 0.014). CONCLUSION Furin expression increased gradually in parallel with the severity of cervical intraepithelial neoplasia. The inflammatory indices were higher in the presence of CC and denoted a good discrimination ability for predicting cervical cancer.

Abstract
Background This study's objective is to determine the slope of the hemoglobin oxygen dissociation curve in critically ill patients who have COVID-19 along with blood gas measurements and how mortality might be impacted by this circumstance. Aim It has been reported that the hemoglobin oxygen dissociation curve is not different from healthy patients in COVID-19. However, there are insufficient data on the behavior of the curve in patients who require intensive care. Patients and Methods This retrospective study was conducted between 01.03.2021 and 01.07.2021 with patients who were followed up due to COVID-19 in adult intensive care unit. P50 and lactate value obtained from in vitro calculated blood gas analysis. The survival status of the patients was recorded. Results The mean P50 value at the admission of nonsurvivors was significantly higher than survivors. In correlation analysis, a significant positive correlation was seen between P50, mortality, and lactate level at admission. SpO2, PaO2/FiO2 ratio, and length of stay in intensive care unit were significantly negatively correlated with P50 levels. Conclusion A right shift in the hemoglobin oxygen dissociation curve is associated with mortality. Lactate levels were also associated with a right shift. Prospective experimental studies are needed to provide a better understanding of this process.

Abstract
PURPOSE Pterygium is defined as overgrowth of abnormal conjunctival tissue on the cornea. Many proinflammatory cytokines and various growth factors have been implicated in the pathogenesis of pterygium. Cyclophilin A (CyPA) is a protein that is used by cyclosporin A (CsA) as the intracellular receptor and is secreted in response to inflammatory stimuli. Vascular endothelial growth factor (VEGF) is the most important angiogenic factor. This study aimed to assessment CyPA and VEGF immunoreactivity in pterygium specimens. MATERIAL AND METHODS In this cross-sectional study, 32 primary pterygium samples, 25 recurrent pterygium samples and 25 normal bulbar conjunctiva samples were included. The histopathological features, CyPA and VEGF immunoreactivity of surgically excised pterygium specimens were compared with control conjunctiva specimens obtained from normal bulbar conjunctiva. RESULTS CyPA immunoreactivity in vascular endothelial cells, epithelial cells, and stromal cells was remarkably higher in pterygium specimens than control conjunctiva specimens (p = 0.004, p = 0.012, p = 0.001, respectively). Morever, VEGF immunoreactivity in endothelial cells was remarkably higher in pterygium specimens than control conjunctiva specimens (p < 0.001). When recurrent and primary pterygium specimens were compared, CyPA and VEGF immunoreactivity was remarkably higher in recurrent pterygium (p = 0.001, p = 0.001, respectively). Pearson correlation showed that CyPA immunoreactivity correlated with stromal vascularity, stromal inflammation, and mast cell count in pterygium specimens. CONCLUSION This study aimed to assess CyPA and VEGF may have a important function in the pathogenesis and recurrence of pterygium.

Abstract
OBJECTIVES To elucidate the link between fetuin-A expression in human umbilical vein endothelial cells (HUVECs) and amnion cells (ACs) and clinicopathological changes in patients with gestational diabetes mellitus (GDM) and newborns. METHODS This retrospective cohort study included 82 pregnant patients (40 with GDM and 42 controls) between January 2019 and January 2022. The patients underwent a one-hour, 50 gram glucose challenge test (GCT) during the 24-28th weeks of pregnancy. Patients with positive GCTs immediately underwent a 3-hour, 100 gram oral glucose tolerance test. The expression level of fetuin-A in UVECs and ACs was evaluated by immunohistochemistry (IHC) and scored based on IHC staining in randomly selected slides. The IHC staining intensity was evaluated by the number of dots, which reflects the expression level of fetuin-A in both HUVECs and ACs. RESULTS The GDM group displayed significantly higher fetuin-A expression in both HUVECs (p<0.0001) and ACs (p=0.0001) when compared with the control group. Fetuin-A expression in HUVECs was correlated with fetal macrosomia, neonatal hypoglycemia, and placental weight. However, there was no correlation with fetuin-A expression in ACs. CONCLUSION There is a correlation between fetal macrosomia, neonatal hypoglycemia, placental weight, and fetuin-A expression of HUVECs in patients with GDM.

Abstract
A six-weeks-old, female kitten presented with dehydration, depression, atresia ani and a discharge of watery feces from the vulvar opening. On radiographic examination, the blind-end of the rectum was determined to be >1 cm cranial from the anal dimple, classifying it as type III atresia ani. Atresia ani combined with a rectovaginal fistula is an uncommon congenital defect of the terminal rectum and anus that can occur in kittens. After supportive medical treatment for three days, the patient was strong enough for surgical correction. The distal rectal pouch was connected to the unperforated anus and the rectovaginal fistula was closed. The kitten recovered uneventfully and was able to defecate normally at 38 weeks follow-up. In this case report, the importance of early surgical correction to avoid potential life-threatening complications from this congenital abnormality is demonstrated.

Abstract
The objective of this study was to investigate proliferation, apoptosis, and antiapoptotic molecule expression in endometrial cells of reproductive-aged women with and without type II diabetes mellitus (T2D). In this case-control study, a total of 80 endometrial tissue specimens from reproductive-aged women (35 in the proliferative phase and 45 in the secretory phase) were examined. The age and body mass index (BMI) were matched between the groups. Formalin-fixed and paraffin-embedded endometrial tissue samples were used for immunohistochemistry analysis. The presence of proliferation was evaluated with Ki-67 expression, antiapoptotic function of cells was evaluated with Bcl-2 expression, and apoptosis was evaluated with terminal deoxynucleotidyl transferase (TUNEL) immunoreactivity in both the glandular epithelium and stroma of endometrial tissue samples from women with and without T2D. Ki-67 expression in the glandular epithelium and Bcl-2 expression in both the glandular epithelium and stroma were significantly higher in endometrial tissue samples of women in the T2D group than the control group (p = 0.0008, p = 0.0022, and p = 0.0261, respectively). TUNEL immunoreactivity was significantly lower in the glandular epithelium of women in the T2D group than the control group (p = 0.0001). Glandular Ki-67 expression correlated positively with BMI, use of insulin, and hemoglobin A1c level (p = 0.0034, p = 0.0154, and p = 0.0011, respectively). Glandular Bcl-2 expression correlated positively with BMI and duration of T2D (p = 0.0090 and p = 0.0109, respectively). Stromal Bcl-2 expression correlated positively with duration of T2D (p = 0.0069). TUNEL immunoreactivity in the glandular epithelium correlated negatively with duration of T2D (p = 0.0340) and positively with the use of oral antidiabetic agents (p = 0.0226). Compared to age and BMI-matched controls, women with T2D experienced increased cell proliferation and decreased apoptosis in the glandular epithelium and increased antiapoptotic function in both the glandular epithelium and stromal cells. High BMI values in women with diabetes seemed to contribute to increased cell proliferation and increased antiapoptotic function in the glandular epithelium but not the stromal cells.

Abstract
BACKGROUND Endometriosis is an estrogen-dependent inflammatory disease that often causes infertility and chronic pelvic pain. Although endometriosis is known as a benign disease, it has demonstrated characteristics of malignant neoplasms, including neoangiogenesis, tissue invasion, and cell implantation to distant organs. Octamer-binding protein 4 (Oct-4) is a molecular marker for stem cells that plays an essential role in maintaining pluripotency and self-renewal processes in various types of benign and malignant tissues. CD44 is a multifunctional cell surface adhesion molecule that acts as an integral cell membrane protein and plays a role in cell-cell and cell-matrix interactions. E-cadherin is an epithelial cell-cell adhesion molecule that plays important role in the modulation of cell polarization, cell migration, and cancer metastasis. The aim of this study was to investigate the expression patterns of Oct-4, CD44, and E-cadherin in eutopic and ectopic endometrial tissues from women with endometrioma compared to control endometrial tissues from women without endometrioma. METHODS In the present study, Oct-4, CD44, and E-cadherin expressions were evaluated in eutopic and ectopic endometrial tissue samples from women with endometrioma (n = 32) and compared with those of control endometrial tissue samples from women without endometrioma (n = 30). RESULTS Immunohistochemical expression of Oct-4 was significantly higher in the ectopic endometrial tissue samples of women with endometrioma than in the control endometrial tissue samples (p = 0.0002). Conversely, CD44 and E-cadherin expressions were significantly lower in the ectopic endometrial tissue samples of women with endometrioma than in the control endometrial tissue samples (p = 0.0137 and p = 0.0060, respectively). Correlation analysis demonstrated significant correlations between Oct-4 expression and endometrioma cyst diameter (p = 0.0162), rASRM stage (p = 0.0343), and total rASRM score (p = 0.0223). Moreover, CD44 expression was negatively correlated with the presence of peritoneal endometriotic lesions (p = 0.0304) while E-cadherin expression was negatively correlated with the presence of deep infiltrating endometriosis (p = 0.0445). CONCLUSIONS Increased expression of Oct-4 and decreased expression of adhesion molecules in endometriotic tissues may contribute to the development and progression of endometriosis.

Abstract
PURPOSE The aim of this study was to evaluate the immunoreactivity of matrix metalloproteinases-2 (MMP-2), intercellular adhesion molecule-1 (ICAM-1), and nesfatin-1 in cataract lens epithelial cells (LECs) of patients with diabetes mellitus (DM) and to investigate the relationship of these markers with DM cataract and diabetic retinopathy (DR). MATERIALS AND METHODS Ninety patients were included in the study. The patients were divided into three groups (n = 30): Group 1 (control; patients without DM or DR); Group 2 (patients with DM only), and Group 3 (patients with both DM and DR). Lens capsule samples were collected during intraoperative cataract surgery. Samples were immunohistochemically stained for MMP-2, ICAM-1, and nesfatin-1 and their immunoreactivity was evaluated. The number of immunoreactive cells was determined with a microscope at ×400 magnification. RESULTS Increased MMP-2 and ICAM-1 immunoreactivity was detected in the LECs of patients with DM, and especially in patients with DR (p < 0.001, p < 0.001, respectively). Nesfatin-1 immunoreactivity was significantly lower in LECs of diabetic patients (p < 0.001). The mean of MMP-2 immunoreactive cells were 7.47 ± 8.18, 22.80 ± 15.70, and 34.80 ± 20.85 in Groups 1, 2, and 3, respectively. The mean of ICAM-1 immunoreactive cells were 17.10 ± 9.83, 38.50 ± 23.55, and 56.93 ± 20.94 in Groups 1, 2, and 3, respectively. CONCLUSION Nesfatin-1, MMP-2, and ICAM-1 and could potentially play important roles in the pathogenesis of cataracts in patients with DM.

Abstract
PURPOSE Pterygium is a common lesion of the ocular surface, and its etiology and pathogenesis are still uncertain. This study aimed to investigate the role of apoptosis and proliferation in pterygium formation and recurrence. MATERIALS AND METHODS In this study, p53, Bcl-2, and Ki-67 expression levels were evaluated in primary pterygium (n = 35) and recurrent pterygium (n = 32) tissue samples and compared with normal conjunctiva (n = 30) tissue samples. In addition, recurrent pterygiums were divided into three groups based on recurrence time, and their p53, Bcl-2, and Ki-67 expression levels were compared. RESULTS The results show that p53, Bcl-2, and Ki-67 expression levels were significantly higher in the pterygium tissue samples as compared to the control group (p < 0.001, p < 0.001, and p < 0.001, respectively). When primary and recurrent pterygium tissues were compared, bcl-2 expression was higher in recurrent pterygium tissue samples (p = 0.003). However, when Ki-67 and p53 expression levels were evaluated, no significant difference was found between primary and recurrent pterygium (p = 0.215, p = 0.321, respectively). Also, p53 and Ki-67 expression were correlated in pterygium tissue samples, and Bcl-2 expression was significantly higher in pterygium that recurrence in the first 6 months after surgery. There was no difference between groups 1, 2, and 3 in terms of p53 and Ki-67 expression. CONCLUSION Antiapoptotic mechanisms and proliferation play an important role in the etiopathogenesis of pterygium. Furthermore, Bcl-2 expression may be important in pterygium recurrence.

Abstract
OBJECTIVE The aim of this study was to investigate the effect of endometriosis on the ocular surface. METHODS A total of 50 patients were included in the study and divided into two groups. Group 1 consisted of 25 patients with endometriosis. Group 2 had 25 control patients. All patients underwent complete ophthalmic examination, and the right eyes were included in the study. To evaluate the ocular surface, both groups were tested with the following: the Schirmer I test, tear breakup time (TBUT), the conjunctival impression cytology (CIC), and the Ocular Surface Disease Index (OSDI). The results were subsequently compared. RESULTS The average Schirmer I test results were 8.40 ± 2.74 mm in group 1 and were significantly lower in patients with endometriosis (P < 0.001). The average TBUT test results were 9.04 ± 3.61 s in group 1 and were significantly lower in patients with endometriosis (P < 0.001). The average OSDI results were 24.04 ± 9.29 in group 1 and were significantly higher in patients with endometriosis (P < 0.001). The average CIC results were 1.76 ± 0.88 in group 1 and were significantly higher in patients with endometriosis (P < 0.001). CONCLUSIONS Ocular surface changes, including squamous metaplasia, may be observed in the conjunctiva of patients with endometriosis.

Abstract
PURPOSE This study aimed to evaluate the differences in the expressions of fractalkine in normal bulbar conjunctiva and primary pterygium tissues. METHODS The study included 48 patients who had been operated on for primary pterygium. Histopathologically, the presence of epithelial atypia, epithelial hyperplasia, goblet cell hyperplasia, epithelial lymphocytic exocytosis, stromal inflammation, mast cell count, and stromal vascularity were evaluated in the primary pterygium tissues. An immunohistochemical fractalkine stain was applied to the primary pterygium tissue samples and normal bulbar conjunctival tissue samples. RESULTS Primary pterygium and normal bulbar conjunctival tissue samples were histopathologically analyzed. Epithelial atypia, epithelial hyperplasia, epithelial lymphocytic exocytosis, stromal inflammation, stromal vascularity, and mast cell count were found to be significantly higher in the primary pterygium (p = 0.001, p = 0.002, p = 0.024, p = 0.007, p = 0.024, and p = 0.013, respectively). When evaluated in terms of fractalkine expression, the epithelial, vascular endothelial, and inflammatory cells were significantly higher in the primary pterygium (p ≤ 0.001, p = 0.002, p = 0.001, respectively). Moreover, compared to the normal bulbar conjunctiva, Ki-67 expression was significantly higher in the primary pterygium tissue samples. CONCLUSION Fractalkine might play a key role in the etiopathogenesis of pterygium. Fractalkine may be important in developing new treatment approaches.

Abstract
Introduction We have aimed to evaluate the difference between the expression of p53, Ki-67, and laminin in keratoacanthoma and well-differentiated SCC (SCC) and to determine its importance in differential diagnosis. Methods This study totally included 46 cases consisting of 23 cases with keratoacanthoma and 23 with SCC. As well as age, gender, localization, and diameter of the lesion, the expression of p53, Ki-67 and laminin was evaluated. Results No statistically significant difference was found between KA and well-differentiated SCC in terms of diameter, age, and localization. There was a statistically significant difference between KA and well-differentiated SCC in terms of p53 and Ki-67 staining (P < 0.001). Increased expression of p53 and Ki-67 was found in well-differentiated SCC. A statistically significant correlation was present between the expression of p53 and Ki-67 in KA. A statistically significant difference was detected between KA and well-differentiated SCC in terms of laminin staining (P = 0.018). Increased laminin expression was determined in well-differentiated SCC. Conclusion We have determined in this study that p53, Ki-67 and laminin may be used as adjuvant immunohistochemical markers in differential diagnosis of KA and well-differentiated SCC.

Abstract
PURPOSE To evaluate serum levels of high-sensitivity C-reactive protein (hs-CRP) in chronic gastritis patients to predict Helicobacter pylori (HP) infection, inflammatory activity, and precancerous lesions. METHODS A total of 811 patients with upper gastrointestinal symptoms and histopathological diagnosis of chronic gastritis were enrolled in the study. On endoscopy, five gastric biopsies were taken according to Modified Sydney protocol, which were stained with hematoxylin & eosin and Giemsa. RESULTS HP infection was found in 28.6% of patients, being significantly more common in specimens with acute and chronic inflammatory activity. Mucosal atrophy, intestinal metaplasia, and dysplasia were found in 20.2%, 18.8% and 2.7% of biopsy specimens. Mean hs-CRP was 1.9±1.6 mg/dl for males and 2.2±1.9 mg/dl for females. hs-CRP average were significantly higher in patients with severe acute inflammation (p:0.049), in patients with severe chronic inflammation (p:0.015) and in those with HP (p: 0.001) . The severity of HP infection increased significantly with the increased degree of acute inflammation, chronic inflammation and hs-CRP level (p=0.001 for both). CONCLUSION Serum hs-CRP level increases in patients with chronic gastritis, it could be an indicator of severity of acute or chronic mucosal inflammation, and presence of HP infection. Therefore, hs-CRP may aid the diagnosis of chronic gastritis, but it is not associated with pre-cancerous lesions.

Abstract
Introduction: Preeclampsia is a systemic inflammatory disorder and a major cause of maternal and fetal mortality. Fractalkine (CX3CL1) is a member of the chemokine family with multiple functions in the organization of the immune system. It is up-regulated in inflammatory disorders. During inflammation, fractalkine enhances tissue destruction and inflammatory cell invasion. We aimed to investigate the alteration of fractalkine in the placental tissues of pregnant women with preeclampsia and the correlation of this alteration with clinicopathological variables.Materials and methods: Alteration of fractalkine in placental tissue specimens was determined immunohistochemically in 84 pregnant women: 33 women with mild preeclampsia, 19 women with severe preeclampsia, and 30 women with normal pregnancy. Preeclampsia was diagnosed using current guidelines of the American College of Obstetricians and Gynecologists.Results: Pregnant women with mild and severe preeclampsia revealed significantly higher fractalkine expression in syncytiotrophoblast cells than in the normotensive group (p = .0051 and .0001, respectively). The expression of fractalkine in preeclampsia was positively correlated with clinical parameters including the presence of intrauterine growth restriction, systolic and diastolic blood pressure, and 24-h urine protein, whereas it was negatively correlated with plasma albumin levels and placental weight. Additionally, the pathological changes in the placenta-including the presence of syncytiotrophoblast basement membrane thickening, increased number of syncytial knots, and vascularization of terminal villi were significantly correlated with fractalkine expression in pregnant women with preeclampsia.Conclusions: Overexpression of fractalkine in pregnant women with preeclampsia, as well as the correlation between fractalkine expression and poor pregnancy outcomes and placental histopathological changes may be associated with the underlying mechanisms of preeclampsia.

Abstract
Endometriosis is defined as the presence of functional endometrial tissues outside of the uterine cavity. Ovarian endometrioma is the most common type of endometriosis. It is an estrogen-dependent inflammatory disease that frequently causes infertility and chronic pelvic pain. Cyclophilin A (CyPA) is secreted from various types of cells in response to inflammatory stimuli. Many previous studies have shown that the increased expression and/or heightened plasma levels of CyPA exacerbates inflammation. The aim of this study is to evaluate CyPA immunoreactivity in ovarian endometrioma cyst wall. In this cross-sectional study, CyPA immunoreactivity in endometrial tissue samples obtained from uterine cavity and in endometrioma cyst walls of 44 consecutive women with ovarian endometrioma were compared with control endometrial tissue samples obtained from uterine cavity of 40 women without endometrioma. All endometrioma samples were confirmed via histopathological examination. Finally, the relationship between CyPA immunoreactivity and the clinicopathological findings related to endometrioma were evaluated. The CyPA expression rates in glandular cells, stromal cells, and the capillary endothelium were significantly higher in endometrioma cyst walls of women with ovarian endometrioma than in the control endometrial tissue of women without endometrioma (p = 0.0002, p = 0.0417 and p = 0.0067, respectively). The correlation analysis demonstrated that glandular CyPA expression was correlated with endometrioma recurrence (p = 0.0267). However, stromal and vascular endothelial CyPA expression were correlated with dysmenorrhea recurrence (p = 0.0023 and p = 0.0003, respectively). In conclusion, the increased expression of CyPA in ectopic endometrial tissue is associated with endometrioma recurrences and vascularity.

Abstract
Previous studies have reported that repeated administrations of linear gadolinium-based contrast agents lead to their accumulation in the brain and other tissues in individuals with normal renal functions. The purpose of this prospective animal study was to investigate the effect of multiple administrations of macrocyclic ionic (gadoteric acid) and linear nonionic (gadodiamide) gadolinium-based contrast agents (GBCAs) on rat testis tissue and to compare these molecules in terms of tissue damage. Thirty-two male Sprague-Dawley rats were kept without drugs for 5 weeks after administration of 0.1 mmol mg-1 kg-1 (0.2 ml/kg) gadodiamide and gadoteric acid for 4 days over 5 weeks. Biochemical, histopathological and immunohistochemical changes in testis tissue were evaluated at the end of 10 weeks. When used in repeated clinical doses, gadolinium was observed to increase apoptosis in the Leydig cells of the rat testis, and to increase serum Ca+2 levels and reduce testosterone levels (p < .05). Although the difference was not statistically significant, a greater loss of spermatozoa and immature germinal cell accumulation were observed in the seminiferous tubule lumen in the GBCA groups compared with the control and saline groups (p > .05). Both linear and macrocyclic contrast agents have toxic effects on testis tissue, irrespective of the type of drug.

Abstract
Endometriosis is an estrogen-dependent inflammatory disease that causes infertility and chronic pelvic pain. Ovarian endometrioma is the most common form of endometriosis, and conservative surgery is the main preferred therapeutic approach for endometrioma-associated symptoms. The aim of this study was to investigate the persistence of cyclic and noncyclic pelvic pain (NCPP) after endometrioma excision and their relationship to clinical and histopathological findings. In this prospective observational study, 41 symptomatic patients were evaluated for the presence of pain symptoms 3 to 6 months after endometrioma excision. Tissue specimens of endometrioma were collected during the operation and embedded in paraffin. The persistence of pain was 41.4%. Surgical excision of endometrioma significantly decreased NCPP and dysmenorrhea, but not dyspareunia ( P < .0001, P = .0001, and P = .25, respectively). Histopathological changes, including depth of endometriosis penetration into the cyst wall, the presence of macrophage infiltration, and vascularity of endometrioma cyst walls were significantly higher in patients with pain persistence than in patients without pain persistence ( P = .0034, P = .0042, and P = .0007, respectively). Moreover, proliferating cell nuclear antigen (PCNA) and CD34 immunoreactivity in both glandular and stromal cells and vascular endothelium were significantly higher in patients with pain persistence ( P = .0079 and P = .0025, respectively). Additionally, these histopathological changes and PCNA and CD34 immunoreactivity were significantly correlated with the persistence of NCPP and dysmenorrhea. The discovered differences in patients with endometrioma with or without pain persistence may indicate a possible relationship between endometrioma-associated pain and histopathological variability of endometrioma.

Abstract
Background Although nasal polyps are one of the most frequent diseases, their etiopathogenesis remains unclear.Since eosinophils are the main inflammatory cells in the substantial proportion of nasal polyp tissues, they are considered potentially responsible for the etiopathogenesis and prognosis of the disease. Aim of this study was to investigate the relation between mucosal and peripheral eosinophilia and their relation with disease severity in nasal polyps. Methods The study included 53 patients with nasal polyps who underwent endoscopic sinus surgery. Preoperative Lund-MacKay computed tomography (CT) scores and the Lund-Kennedy endoscopic scores of the patients were recorded. Nasal polyp tissues were stained with hematoxylin and eosin, eosinophil counts were performed using high-power field (HPF, 400×) under the light microscope, and the patients were grouped as those with high mucosal eosinophil count and those with low mucosal eosinophil count. Results The mean Lund-MacKay CT score and the mean Lund-Kennedy endoscopic score were higher in the patients with high mucosal eosinophil count than in those with low mucosal eosinophil count. Likewise, the mean Lund-MacKay CT score and the mean Lund-Kennedy endoscopic scores were significantly higher in the patients with high peripheral eosinophil count than in those with low peripheral eosinophil count (p < 0.05 for both). Moreover, the mean peripheral eosinophil count was significantly higher in the patients with high mucosal eosinophil count than in those with low mucosal eosinophil count (p < 0.05). Conclusion Mucosal and peripheral eosinophilia can be used as a marker to predict disease severity in nasal polyps.

Abstract
Background: Although nasal polyps are one of the most frequent diseases, their etiopathogenesis remains unclear. Since eosinophils are the main inflammatory cells in the substantial proportion of nasal polyp tissues, they are considered potentially responsible for the etiopathogenesis and prognosis of the disease. Aim of this study was to investigate the relation between mucosal and peripheral eosinophilia and their relation with disease severity in nasal polyps.
Methods: The study included 53 patients with nasal polyps who underwent endoscopic sinus surgery. Preoperative Lund-MacKay computed tomography (CT) scores and the Lund-Kennedy endoscopic scores of the patients were recorded. Nasal polyp tissues were stained with hematoxylin and eosin, eosinophil counts were performed using high-power field (HPF, 400×) under the light microscope, and the patients were grouped as those with high mucosal eosinophil count and those with low mucosal eosinophil count.
Results: The mean Lund-MacKay CT score and the mean Lund-Kennedy endoscopic score were higher in the patients with high mucosal eosinophil count than in those with low mucosal eosinophil count. Likewise, the mean Lund-MacKay CT score and the mean Lund-Kennedy endoscopic scores were significantly higher in the patients with high peripheral eosinophil count than in those with low peripheral eosinophil count (p < 0.05 for both). Moreover, the mean peripheral eosinophil count was significantly higher in the patients with high mucosal eosinophil count than in those with low mucosal eosinophil count (p < 0.05).
Conclusion: Mucosal and peripheral eosinophilia can be used as a marker to predict disease severity in nasal polyps.

Abstract
AIM The aim of this study was to examine the acute effects of static stretching in dominant leg flexor muscle groups on concentric isokinetic leg extension and flexion peak torque (PT), peak torque % body weight (PT%BW) and total work (TW) at 60, 180 and 300 °.s-1 in stretched and non-stretched limbs of modern dancers. METHODS Twenty-six trained modern dancers volunteered in this study. On the first measurement, isokinetic tests were performed on dominant and non-dominant legs. On the second measurement, the dominant leg flexors were stretched using 3 unassisted and 1 assisted static stretching exercises (each 4x15 seconds; 10-second rest). After the stretching, isokinetic tests were repeated on both legs. RESULTS The results indicated a positive increase in strength in the stretched (PT%BW, TW) and non-stretched (PT, PT%BW, TW) limbs in flexion at 180°s-1 (P<0.05). We observed a positive increase (P<0.05) in the stretched limb (180 and 300°.s-1, TW; 300°.s-1, PT%BW) in extension whereas an acute decrease (P<0.05) was observed in both legs (60˚.s-1, PT and PT%BW). CONCLUSION Our findings indicated a possible positive effect of static stretching at high angular velocities on the strength production of isokinetic contraction in stretched and non-stretched muscles. However, due to its negative effect on the extensor muscle groups, we think using static stretching is required attention before maximal strength exercises.

Abstract
Left ventricular hypertrophy, dehydration, sepsis, vasodilatation, excessive sympathetic stimulation, pericardial tamponade and surgical treatment of the atrioventricular valve are known causes of left ventricular outflow tract (LVOT) obstruction. We report the rare case of a patient who developed dynamic LVOT obstruction as a complication of acute pulmonary embolism.

Abstract
BACKGROUND The aim of the present study was to determine whether regular exercise training (ET) is effective at promoting the mobilization of CPCs and improving their functional activity in patients with recently acquired myocardial infarction (STEMI). Regular physical training has been shown to improve myocardial perfusion and cardiovascular function. This may be related in part to a mobilization of bone marrow-derived circulating progenitor cells (CPCs) as well as an enhanced vascularisation. METHODS 37 patients with STEMI were randomly assigned to an ET group or a non-ET group (controls). Two weeks after STEMI, three weeks after regular ET and three months after ET, BNP levels, exercise echocardiography and exercise spiroergometry were evaluated. The number of CD34+/CD45+ and CD133+/CD45+ CPCs was measured by flow cytometry analysis. The migration capacity of the CPCs was determined with a boyden chamber and the clonogenic capacity by CFU-assay. RESULTS In the ET-group the number and migration capacity of CPCs increased significantly after regular exercise training. The BNP level decreased significantly from 121 +/- 94 to 75 +/- 47 pg/ml (p<0.001) after the ET period, the left ventricular ejection fraction raised in parallel at peak exercise, and the cardiorespiratory condition improved as demonstrated by an increase of VO2max (from 1641 +/- 522 to 1842 +/- 724 ml/min, p<0.02). These three effects persist till three months after the ET period. CONCLUSIONS Regular physical activity appears to predispose the mobilization and enhanced functional activity of CPCs, a phenomenon which might lead to an improved cardiac function in patients with recently acquired acute myocardial infarction.

Abstract
In the present study, the incidence and antimicrobial resistance patterns of the microorganisms that caused bloodstream infections (BSIs) in a medical-surgical intensive care unit during the years 2005-2007 were determined. The mean BSI incidence density was 6.56 per 1000 patient-days. The incidence density increased linearly during the study period (from 3.57 to 9.60 per 1000 patient-days). Staphylococcus aureus was most frequently isolated (47.3%), followed by Enterococcus spp. (10.8%) and Candida spp. (10.1%). There was a high rate of resistance to several of the prescribed antimicrobials among the bacteria isolated from patients with BSIs.
