Antioxidant activity of CAPE (caffeic acid phenethyl ester) in vitro can protect human sperm deoxyribonucleic acid from oxidative damage.

Purpose: Sperm processing (e.g., centrifugation) used in preparation for assisted reproduction can result in excessive generation of reactive oxygen species (ROS) and potential sperm damage.

Reflectance confocal microscopic evaluation of nonmelanocytic lip lesions.

Lips display various benign and malignant lesions. Considering their functional and cosmetic importance, noninvasive diagnostic methods are required. In vivo reflectance confocal microscopy (RCM) has already been reported to be useful in the evaluation of various skin lesions.

Diaphragmatic resection preserving and repairing pericardium, splenectomy and distal pancreatectomy for ınterval debulkıng surgery of ovarıan cancer.

Objective: The majority of ovarian cancer patients are initially diagnosed at an advanced-stage [1]. Upper abdominal bulky metastasis cephalad to the greater omentum reported to be present in 42% of patients [2]. Many complex surgical procedures such as splenectomy, pancreatectomy, mobilization and partial resection of liver, porta hepatis dissection, diaphragmatic peritonectomy and resection are frequently performed to achieve complete resection of metastatic disease [3].

The effects of different intraabdominal pressure protocols in laparoscopic procedures on oxidative stress markers and morphology in rat ovaries.

Background: To determine the effects of different intraabdominal pressure (IAP) on the ovaries in a laparoscopic rat model.

Objectives: The aim of the study was to determine the effects on the ovaries of different intraabdominal pressures (IAP) in laparoscopic surgery in a rat model.

Material And Methods: Thirty-two post-pubertal nonpregnant Sprague-Dawley rats were divided randomly into four groups.

Induced growth inhibition, cell cycle arrest and apoptosis in CD133+/CD44+ prostate cancer stem cells by flavopiridol.

Flavopiridol is a flavone that inhibits several cyclin‑dependent kinases and exhibits potent growth‑inhibitory activity, apoptosis and G1‑phase arrest in a number of human tumor cell lines. Flavopiridol is currently undergoing investigation in human clinical trials. The present study focused on the effect of flavopiridol in cell proliferation, cell cycle progression and apoptosis in prostate cancer stem cells (CSCs).

Significance of apoptosis related proteins on malignant transformation of ovarian tumors: A comparison between Bcl-2/Bax ratio and p53 immunoreactivity.

In this study, we compared the immunoreactivities of Bcl-2, Bax and p53 proteins in ovarian tumors and related the immunohistochemical findings to the histological type of the tumors. Formalin-fixed, paraffin wax-embedded tissue sections from 40 patients who had serous-mucinous borderline tumors and serous-mucinous adenocarcinoma of the ovary (n=10 each) were stained with hematoxylin-eosin (H&E). After histopathological examination, serial sections were stained immunohistochemically with primary antibodies to Bcl-2, Bax and p53 using an avidin-biotin-peroxidase method.

Expression profiling of stem cell signaling alters with spheroid formation in CD133/CD44 prostate cancer stem cells.

Cancer stem cells (CSC) isolated from multiple tumor types differentiate and when cultured in serum; however, the factors responsible for their differentiation have not yet been identified. The first aim of the present study was to identify CD133/CD44 DU145 prostate CSCs and compare their profiles with non-CSCs as bulk counterparts of the population. Subsequently, the two populations continued to be three-dimensional multicellular spheroids.

Cancer stem cell differentiation: TGFβ1 and versican may trigger molecules for the organization of tumor spheroids.

Cancer stem cells (CSCs) have the ability to self-renew similar to normal stem cells. This process is linked with metastasis and resistance to chemotherapy and radiotherapy. In the present study, we constructed an in vitro differentiation model for CSCs.

Notch signaling-related therapeutic strategies with novel drugs in neuroblastoma spheroids.

Neuroblastoma is a severe pediatric tumor characterized by poor prognosis. Identification of novel molecular targets and diversion of investigations on new drug trials is mandatory for cancer therapy. In this study, vinorelbine tartrate, lithium chloride, clomipramine, and medroxyprogesterone acetate are used for the possible new treatment modalities in neuroblastoma cells.

The value of frozen section evaluation in the management of borderline ovarian tumors.

Purpose: To evaluate the accuracy of a frozen section and to analyze the factors affecting frozen section results in cases of borderline ovarian tumors (BOTs).

Materials And Methods: The files and pathological reports of 82 cases diagnosed with BOT at our clinic, between January 1994 and June 2009, have been retrospectively evaluated. The frozen section results were compared to the permanent paraffin section results.

Second primary cancers following borderline ovarian tumors.

Background: Several studies have reported an increased risk of second primary cancers subsequent to invasive epithelial ovarian cancer. However, there is no adequate data regarding such risk in borderline ovarian tumors (BOTs). The aim of this study was to evaluate the risk of subsequent second primary cancers among women with BOTs.
