[ 1 ] - Evaluation of Immature Neutrophil Ratio and Calprotectin Level for the Diagnosis of Neonatal Sepsis
Background: Sepsis is defined as a systematic inflammatory reaction against infection. Despite the recent advances in medical and pediatric sciences, sepsis remains a significant life-threatening health issue. The main problem associated with this disorder is the nonspecific and non-discriminative symptoms of noninfectious diseases. The present study aimed to introduce diagnostic parameters of ...
[ 2 ] - The Association of Gastritis and Peptic Ulcer With Polymorphisms in the Inflammatory-related Genes IL-4 and IL-10 in Iranian Population
Background and Objective: The current study aimed at assessing the relationship between gastritis and peptic ulcer susceptibility and inflammation-related gene polymorphisms in Iranian patients. Gastritis and peptic ulcer are common medical complications with serious outcomes on the quality of life. Inflammatory responses of gastric mucosa are associated with helicobac...
[ 3 ] - KRAS Codon 12 and 13 Mutations in Gastric Cancer in the Northeast Iran
Background & objective: KRAS mutations are reported in many types of cancers including pancreas, lung, colon, breast, and gastric (GC). High frequency of KRAS mutation is observed in the pancreas, colon, and lung cancers; they commonly arise in codon 12 and 13 of exon 2. Due to the lack of information about the frequency of KRAS</...
[ 4 ] - Chromogenic in situ Hybridization Compared with Real Time Quantitative Polymerase Chain Reaction to Evaluate HER2/neu Status in Breast Cancer
Background and objective: The assessment of human epidermal growth factor receptor 2 (HER2) status has become of great importance in the diagnosis of breast cancer. The aim of this study was to investigate the diagnostic value of quantitative Polymerase Chain Reaction (qPCR) and Chromogenic In Situ Hybridization (CISH) to assess HER2 status of biopsy specimens. <...
[ 5 ] - Fluorescent in Situ Hybridization and Real-Time Quantitative Polymerase Chain Reaction to Evaluate HER-2/neu Status in Breast Cancer
Background:Breast cancer remains the most common and second lethal cancer in females. HER-2/neu is one of the most important amplified oncogene in breast cancer. The amplification of HER-2 is correlated with decreased survival, metastasis, and early recurrence. The amplification of HER-2/neu gene and synthesis of th...
[ 6 ] - Analysis of BAALC gene Expression as prognosis factor in Pediatric Acute Myeloid Leukemia in Iran
Background:Brain and Acute Leukemia Cytoplasmic (BAALC) is a gene which its expression is confined to progenitor cells; therefore, no expression has been illustrated in mature cells of bone marrow or white blood cells (WBC). In addition, high BAALC expression is associated with poor prognosis in Acute Myeloid Leukemia (AML) individuals and is considered as an important risk factor in Cyto...
[ 7 ] - Evaluation of BAALC gene expression in normal cytogenetic acute myeloid leukemia patients in north-east of Iran
Background: Acute myeloid leukemia (AML) is known as one of the most common leukemia among adults. Environmental and different genetic factors affect disease process, prognosis and treatment. Among different genetic factors NPM1, FLT3, MLL and BAALC genes are the most effective on patient's survival rate. The aim of this study was to assess amount of BAALC gene expression in AML patients, and i...
[ 8 ] - Prevalence of MPL (W515K/L) Mutations in Patients with Negative-JAK2 (V617F) Myeloproliferative Neoplasm in North-East of Iran
Background and Objective: Janus kinase 2 (JAK2) and Myeloproliferative Leukemia (MPL) mutations are confirmatory indicators for Myeloproliferative Neoplasm (MPN). The current study was performed to determine the frequency of MPL mutation in MPN patients without JAK2 mutation, in order to assign MPL mutation frequency in North-East of Iran.Methods: Total o...
[ 9 ] - Molecular Status of BRAF Mutation in Prostate Adenocarcinoma: The Analysis of 100 Cases in North-East of IRAN
Background and Objective: BRAF mutations were studied in various populations for prostate carcinoma (PC); however, mutations in BRAF gene are unusual compared to KRAS. Oncogenic activating of BRAF mutations were studied lately in almost 0%-10% of prostate cancer cases. Methods: In this retrospective study, we gathered 100 formalin-fixed ...
[ 10 ] - 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...
[ 11 ] - Expression of ROR1 Gene in Patients with Acute Lymphoblastic Leukemia
Background: Acute lymphoblastic leukemia (ALL) results from genetic alterations in a single lymphoid progenitor cell. Expression of ROR1 is reported to be increased in ALL and mantle cell lymphoma. In this study the expression of ROR1 was assessed in newly diagnosed patients with ALL. Methods: This study was carried out on 40 patients with newly diagnosed ALL and healthy individuals as contro...
[ 12 ] - 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...
[ 13 ] - The Survival of Patients with t(15;17)(q22;q12) Positive Acute Promyelocytic Leukemia: A Study in North-East of Iran
Background & Objective: Acute promyelocytic leukemia (APL) with t(15;17)(q22;q12) is a relatively common subtype of acute myeloid leukemia (AML). Here, our objective was to ascertain the survival of patients with this leukemia in north-east of Iran. Methods: Survival rates of 42 APL patients with t(15;17)(q22;q12) were assessed. Clinical information was ...
[ 14 ] - NUDT15 genetic variants and 6-mercaptopurine intolerance in pediatric acute lymphoblastic leukemia: an updated review
Acute lymphoblastic leukemia (ALL) accounts for nearly 30% of pediatric cancers. The maintenance treatment for ALL comprises daily oral 6-mercaptopurine (6-MP) and weekly methotrexate (MTX). 6-MP is a purine analog that can significantly improve the long-term survival of ALL patients. Despite more than 90% of 5-year survival of childhood ALL in developed countries, treatment interruption due to...
