Objectives: The antioxidant capacity impairs in kidney and urinary bladder of animals with stone disease. Herbal medicine can improve the antioxidant condition of renal tissue. Cynodon dactylon (C. dactylon) is a medicinal plant with antioxidative and diuretic properties and different preparations of this plant have shown promising effects in stone disease. Assessment of the whole plant decocti...

[ 2 ] - The protective effect of Nigella sativa against cisplatin-induced nephrotoxicity in rats

Objective: The clinical use of cisplatin is highly restricted, because of its nephrotoxicity.In this study the protective effect of Nigella sativa (N. sativa) against cisplatin-induced nephrotoxicity was investigated in rats. Materials and Methods: In the current study, the effects of the administration of aqueous-ethanolic extract of N. sativa (100 and 200 mg/kg, BW) and vitamin E (100 mg/kg, ...

[ 3 ] - The diagnostic value of TTF1, P63, HMWK [34βE12], CK7, and CD56 immunostaining in classification of lung carcinoma

Background & objective: The histologic distinction of small cell from non-small cell lung carcinoma and correct identification of all subtypes of lung carcinoma are very important in treatment management. The main method for histologic classification of lung tumors is based on morphology. However, in small bronchoscopic biopsies in par...

[ 4 ] - بررسی ارزش یافته ‌های آنالیز تصویری در تشخیص سایتولوژیک اسمیرسرویکو واژینال

مقدمه: روش های آنالیز تصویری امروزه دارای اهمیت فراوانی به عنوان روش کمکی در تشخیص های پاتولوژیک است و این روش ها می ‌توانند به عنوان یک روش موازی باعث افزایش دقت و سرعت ارزیابی نمونه ها شوند. مواد و  روش ها: این مطالعه از نوع مشاهده ای-مقطعی بر روی 50 مورد از نمونه های اسمیر سرویکوواژینال انجام شد که به بخش آسیب شناسی بیمارستان قائم مشهد ارجاع شده بود. ابتدا تمام نمونه ها بر اساس سیستم بتسدا د...

[ 5 ] - The Relationship Between Fibroblastic Growth Factor Receptor-1 (FGFR1) Gene Amplification in Triple Negative Breast Carcinomas and Clinicopathological Prognostic Factors

Background & Objective: In Triple-Negative Breast Cancers (TNBCs), estrogen receptor (ER), progesterone receptor (PR) and HER2/neu genes are not expressed. Fibroblastic Growth Factor Receptor-1 (FGFR1) gene product is a protein that acts as a receptor of thyrosin kinase. It plays a role in the proliferation, differentiation, and migration of malignant cells. The objective was t...

[ 6 ] - Vascular Mimicry Expression in Invasive Ductal Carcinoma; A New Technique for Prospect of Aggressiveness

Background & Objective: In vascular (vasculogenic) mimicry (VM), tumoral cells mimic the endothelial cells and form the extracellular matrix-rich tubular networks. It has been proposed that VM is more extensive in aggressive tumors. This study was designed to investigate the rate of VM expression in the stromal cells of invasive ductal carcinoma (IDC) and to find its relationsh...

[ 7 ] - Evaluation of Cyclooxygenase-2 Expression in Association with Clinical-Pathological Factors in Malignant Melanoma

Background and Objective: The primary goal of this study is to develop a rigorous understanding ofthe correlation between COX-2 expression and malignant melanoma prognostic factors. Material and Methods: In this cross-sectional study, we analyzed 60 cases of cutaneous malignant melanoma. The related stained slides were reviewed by two pathologists. The re...

[ 8 ] - Epstein-Barr Virus and Human Herpesvirus 8 in Idiopathic Pulmonary Fibrosis

Background & Objective: Idiopathic pulmonary fibrosis (IPF) is a chronic and uniformly fatal interstitial lung disease with incompletely understood pathogenesis. Several studies have given the evidence for and against viral cofactors in the pathogenesis of Idiopathic pulmonary fibrosis. In this study Epstein-Bar Virus (EBV) and Human Herpesvirus 8 (HH...

[ 9 ] - Hydro-Ethanolic Extract of Portulaca Oleracea Ameliorates Total and Differential WBC, Lung Pathology and Oxidative Biomarkers in Asthmatic Rats

Objective: The effects of Portulaca oleracea (P. oleracea; PO) on total and differential WBC count, and oxidant/antioxidant biomarkers in bronchoalveolar lavage fluid (BALF) as well as on lung pathology in asthmatic rats were examined. Methods and Methods: Rats were randomly divided into; control group (C), asthma group, asthma groups treated with either P. oleracea (rats that received P...

[ 10 ] - Hydro-Ethanolic Extract of Portulaca Oleracea Ameliorates Total and Differential WBC, Lung Pathology and Oxidative Biomarkers in Asthmatic Rats

Objective: The effects of Portulaca oleracea (P. oleracea; PO) on total and differential WBC count, and oxidant/antioxidant biomarkers in bronchoalveolar lavage fluid (BALF) as well as on lung pathology in asthmatic rats were examined. Methods and Methods: Rats were randomly divided into; control group (C), asthma group, asthma groups treated with either P. oleracea (rats that received P...

[ 11 ] - Evaluation of CD133 and CD56/NCAM expression in Wilms tumor and their association with prognostic factors

Objective(s): To validate certain markers for cancer stem cell populations and their clinical importance in Wilms tumor (WT)Materials and Methods: Immunohistochemical study for CD133 and CD56/NCAM was performed on forty-six cases of WT that were diagnosed between 1999 and 2015, and the association of these markers with survival and progn...

[ 12 ] - Liposomal gp100 vaccine combined with CpG ODN sensitizes established B16F10 melanoma tumors to anti PD-1 therapy

Objective(s): Program death 1 (PD-1)/ program death-ligand 1 (PD-L1) pathways, as the main inhibitory checkpoints, induce immunosuppression in the tumor microenvironment (TME). Despite the importance of inhibitor checkpoint receptor (ICR) blockers, their outcomes have been limited by the low immune response rate and induced acquired resistance. Pre-existing tumor-speci...
