The effect of thermal energy due to drilling around the facial nerve canal on the facial nerve was histopathologically evaluated in four guinea pigs. The bony canal of the facial nerve was drilled using a 3 mm diamond burr for one minute. The temperature changes on the facial nerve canal were noted before and after dissection. The temporal bones of the(More)
OBJECTIVE To investigate the embryonic and endometrial effects of anastrozole in preimplantation and implantation phases in FSH-induced cycles in mice. DESIGN Blind randomized study. SETTING University research laboratory. ANIMAL(S) Twenty-seven mature female mice. INTERVENTION(S) Single-dose anastrozole (25 mg/kg [0.75 mg]), recombinant FSH (5(More)
BACKGROUND & OBJECTIVES Sildenafil citrate is an oral medication used to treat male impotence by the inhibition of phosphodiesterase-5 in the corpus cavernosum and subsequent facilitation of penile erection. Though the ocular side effects of sildenafil have been reported, no information is available on the histopathologic effects of chronic use of(More)
Integrins are a large family of cell adhesion molecules that serve as receptors involved in cell-to-cell and cell-to-matrix interactions during implantation. We studied immunohistochemical staining of integrins (alpha 3, alpha V, beta 1, and alpha 2 beta 1) and fibronectin in ectopic tubal pregnancy. Thirty fallopian tube samples with ectopic pregnancies(More)
Gemcitabine, which induces S-phase arrest, and Vinorelbine, which arrests microtubule organization, are two agents that have demonstrate preferred anti-tumor activity. Nitric oxide acts in diverse functions including anti-tumor and anti-pathogenic activities. In this study, we aimed to examine the distribution of immunoreactivities of inducible nitric oxide(More)
Bone marrow is a complex tissue composed of hematopoietic and stromal stem cells with the potential to differentiate into adipogenic, fibroblastic, reticular, osteogenic and chondrogenic lineages. Identification of differentiation markers during transformation of stromal cells into osteoblasts in a time-dependent manner may be informative for cell-based(More)
BACKGROUND/PURPOSE The maturity of neomucosa growing on a serosal surface for the treatment of short bowel syndrome still is questionable. The aim of this study was to evaluate the intestinal neomucosa to assess its histologic maturity. METHODS A 6-cm-long isolated ileal segment (IS) was prepared in 8 Wistar albino-type rats. The IS was divided from the(More)
Aberrant activation of the JAK/STAT pathway may predispose to malignancy as a consequence of the deregulation of cell proliferation, differentiation or apoptosis such as in cancer of the blood, head and neck, and breast. In our study we aimed to investigate the effects of 5-fluorouracil (5-FU) and gemcitabine on a breast cancer cell line (MCF-7 cells) via(More)
Sildenafil citrate (Viagra) is widely used for the treatment of erectile dysfunction with various etiologies. The aim of the present study was the investigation of histopathological effects of sildenafil citrate on rat corpus cavernosum using tight and electron microscopical techniques. Twenty male rats were divided into two groups. The first group (n = 10)(More)
Intrauterine contraception is the most cost-effective reversible method of contraception today, but its mechanism of action is not well understood. Our objective was to investigate immunohistochemical distribution patterns of alphav, alpha3, beta1 integrins in women using a copper T380 intrauterine device (IUD) for different periods of time to obtain(More)
