It is established that gestation against decreases production syncytiotrophoblast chorionic villi correlates with state blood pregnant woman. optical density immunohistochemical staining for free troph...

Aims: the aim of this study is RPD3 expression in clinicopathological characteristics CRC patients and to existence a relationship between HPV samples Iraqi patients. Material methods: 30 formalin-fixed, paraffin-embedded archival tissues from were obtained, together with 10 normal tissue (free cancer), for immunohistochemical analysis expression. Results: Immunohistochemical (IHC) staining rev...

Background and Aim: Mucoepidermoid carcinoma (MEC) is the most common malignant neoplasm of the salivary glands with complex histopathologic features and clinical behavior. The aim of this study was to evaluate the clinicopathologic significance of p63, Maspin and matrix metalloproteinase (MMP)-2 expression in MEC. Materials and Methods: In this retrospective study, immunohistochemical stain...

AIM To carry out an objective assessment of two systems of scoring immunohistochemical staining, evaluating interobserver and intraobserver error. METHODS 92 cervical tumours underwent immunohistochemical staining for p53 and epidermal growth factor receptor. Staining was assessed using two methods: a standard 4 point scale and a descriptive method, performed by three observers. Interobserver...

The thymus plays an essential role in the maturing of progenitor cells to functional T cells. Recent studies suggest that the Hedgehog (Hh) signaling pathway contributes to this differentiation process. However, there is limited information concerning the expression of Hh pathway-related proteins (Hh proteins) in the human thymus. The staining of Hh proteins in the thymic epithelium of 26 surgi...

Extraocular muscle biopsies from normal individuals and five patients with Graves' ophthalmopathy were analyzed by immunohistochemical staining. Fibroblasts in normal extraocular muscle as well as Graves' extraocular muscles expressed HLA-class II antigens, but the muscle cells did not. There was an increase of interstitial tissue in Graves' extraocular muscles but no visible damage to the musc...

back ground: the aim of this study was to characterize the immunohistochemical expression of galectin 1, 3, and 9 in normal oral epithelium, oral squamous papilloma, and oral squamous cell carcinoma. materials and methods: immunohistochemical staining for galectins 1, 3, and 9 was evaluated in 8 samples of normal oral squamous epithelium, 15 samples of oral squamous papilloma, and 41 samples of...

BACKGROUND The diagnosis of Hirschsprung's disease (HD) is based on the absence of ganglion cells. In hemotoxilin and eosin (H and E) as well as acetylcholine esterase staining there are limitations in the diagnosis of immature ganglion cells in neonates. METHODS In this prospective study, 54 biopsies taken from suspected HD patients (five mucosal specimens and 49 full thickness specimens) we...

UNLABELLED Prostate cancer is a major public health problem in the world. Molecular studies are necessary for the development of prognostic markers in prostate cancer. There is a great interest in mucin studies in treatment development of human malignancies, including prostate cancer. Nevertheless, their expressions in prostate cancer need further investigation. MATERIALS AND METHODS Mucin 1 ...
