CONTEXT Products of at least five specific steroidogenic genes, including steroidogenic acute regulatory protein (StAR), which facilitates the entry of cytosolic cholesterol into the mitochondrion, side chain cleavage P450 enzyme, 3beta-hydroxysteroid-dehydrogenase-2, 17-hydroxylase/17-20-lyase, and aromatase, which catalyzes the final step, are necessary(More)
Chemokines and their receptors play diverse roles in malignant tumor progression, particularly as key mediators of tumor stroma interactions. C-C motif chemokine ligand 2 (CCL2) also called monocyte chemoattractant protein-1 (MCP-1), belongs to the C-C motif chemokine sub-family and is currently believed to mediate its actions through one receptor, C-C(More)
In a full-text natural-language retrieval system, frequent need for automatic hngulst~c analysis arises, e.g for keyword expansion in a search process, content analysis, or automatic construction of concordances The avadablhty of sophisticated hngulstic tools, which is highly desirable for languages such as Enghsh, is quite imperative for, say, Semmc(More)
OBJECTIVE To determine the effects of letrozole and melatonin on surgically induced endometriosis in a rat endometriosis model. DESIGN Prospective, randomized, controlled, experimental study. SETTING Experimental Research Center of Yeditepe University (YUDETAM). ANIMAL(S) Thirty female, nonpregnant, nulligravid Wistar-Hannover albino rats. (More)
Several improvements in ovarian cancer treatment have been achieved in recent years, both in surgery and in combination chemotherapy with targeting. However, ovarian tumors remain the women's cancers with highest mortality rates. In this scenario, a pivotal role has been endorsed to the immunological environment and to the immunological mechanisms involved(More)
BACKGROUND/AIMS Endometriosis is regarded as a complex disese, in which genetic and environmental factors contribute to the disease phenotype. Whether vascular endothelial growth factor (VEGF) -460 C/T and +405 G/C polymorphisms are associated with susceptibility to endometriosis was investigated. PATIENTS AND METHODS Diagnosis of endometriosis was made(More)
OBJECTIVE We aimed to evaluate the knowledge and interest level of Turkish women about HPV, HPV vaccines and cervical cancer using a questionaire. METHOD A 25-item questionnaire was distributed to women in three different cities located in separate sociocultural locations. RESULTS At the closure of the study 143 women responded and returned the survey.(More)
Several polymorphisms in the DNA repair gene are thought to have significant effects on cancer risk. We investigated the association of polymorphisms in the DNA repair genes XRCC1 Arg399Gln, XRCC3 Thr241Met, XPD Lys751Gln, XPG Asp1104His, APE1 Asp148Glu, and HOGG1 Ser326Cys with endometriosis risk. Genotypes were determined by PCR-RFLP assays in 52 patients(More)
AIM To evaluate the efficacy of hyaluronate/carboxymethylcellulose (HA/CMC) membrane and melatonin separately and in combination in reducing adhesion reformation following adhesiolysis of surgically induced adhesions in a rat uterine horn adhesion model. METHODS A randomized, prospective study was carried out in a university animal laboratory.(More)
