The infection with H. Pylori stimulates a signaling cascade that causes the generation of Cytokines and provokes Oxidative stress that is involved in the chronic inflammatory response leads to Gastric cancers. Reactive oxygen species (ROS) produce 8-Hydroxydeoxyguanosine (8-OHdG), the persistent oxidative DNA damage product. The study objective was to assess if there was a link between inflammatory cytokine levels and the presence of Oxidative DNA damage in Gastric tumor patients. In addition, evaluation of the diagnostic and prognostic value of Oxidative DNA damage and inflammatory cytokine biomarkers for Stomach cancers is being conducted. The study was accomplished on medically diagnosed Stomach cancer patients before any form of treatment. A total of 33 patients with Gastric cancers were selected and divided into Stages I, II, and III according to clinical pathology, and 32 age-matched healthy subjects as a control group. The Serum 8-OHdG, IL-6, TNF-α, IFN-γ & CEA were evaluated. The results revealed a highly significant rise (P<0.0001) in blood levels of 8-OHdG, TNF-α, & IFN-γ, and a non-significant (P=0.4747) increasing in IL-6 in GC patients compared to Controls, with levels gradually increasing as disease stages progressed. Furthermore, in GC patients, there was an insignificant (P=0.3472) positive correlation (r=0.1292) among 8-OHdG, IL-6, and CEA levels, but a noteworthy (P<0.0001) positive correlation (r=0.7235) among 8-OHdG, TNF-α, and CEA levels. In GC patients, however, there was an insignificant (P=0.6342) negative correlation (r=-0.06559) among 8-OHdG, IFN-γ, and CEA levels. The results of the current study show a strong link between serum levels of the 8-OHdG as well as inflammatory cytokines in GC patients. The significant enhancement in oxidative DNA damage, as well as overexpression of inflammatory cytokine biomarkers and CEA in the blood suggests that Oxidative stress and chronic inflammation are included in GC carcinogenesis. These observations suggest that 8-OHdG, TNF-α, & IFN-γ are viable biomarkers for the Gastric tumor prediction.
Abstract
Background: Diabetes mellitus is the most common endocrine illness, affecting an increasing number of people all over the world. It is caused by a lack, or inadequate synthesis of insulin by the pancreas leading to an increase in blood glucose concentrations. Type 2 diabetes mellitus is the most strongly linked disease to obesity of all disorders. The number of obesity-related diabetes is predicted to reach 300 million by 2025. The term 'diabesity' was coined as a result of this strong link, therefore, weight loss is seen as a key therapeutic goal in the prevention and management of type 2 diabetes mellitus. Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agon

Systemic lupus erythematosus (SLE) is the prototypic immune complex disease, characterized by excessive autoantibody production, immune complex formation and immunologically mediated tissue injury.
Methods& Patients: A cross-sectional study was conducted on two main groups ,74 patients with SLE and 30 apperantly healthy control volunteers referred to immunology department in teaching laboratories \ medical city during period of (1st of march – 31st of May) 2011. Antinuclear antibody (ANA) ,Cathepsin&n
Background: The discriminative power of the classical WHO parameters in relation to male fertility is quite low, because they only address few aspects of sperm quality and function. This has led investigators to focus their attention on the male gamete and in particular its genome.Objective: To explore which of the sperm DNA damage parameters measured by comet assay are more reliable, and their relations with the standard semen parameters.Methods: Study was done on 40 infertile men selected from couples attending the Institute of Embryo Reasearch and Infertility Treatment at Al-Kadhimiya City/ Baghdad in the period between February 2009 and May 2009, with a history of infertility of ≥1 years; and 15 healthy volunteers of proven fertili

The immunoglobulin (IG) Program death ligand-1(PD-1) cell surface receptor is predominantly expressed on the surface of many cells. The purpose of this study was to demonstrate the relationship between Program death ligand expression and some aggressive features of prostate cancer including perineural invasion, vascular invasion and necrosis. Thirty cases of prostate cancer with age range from 60 to 80 year old and 30 cases of normal prostate tissue with age under 25 year old were separated into two groups in a retrospective case-control

Patients and methods: A descriptive analytical study was conducted on a purposive sample of 50 cancer patients from both sexes who were admitted to Radiation and Neuclur Medicine Hospital in Baghdad for the purpose of giving chemotherapy for the period from April 4th to June 20th , 2008.

Background: Diabetes mellitus is a chronic metabolic disorder of the carbohydrate, protein and fat metabolism, resulting in increased blood glucose levels. Various complications of diabetes have been described with periodontitis being added as the sixth complication of diabetes mellitus. Matrix metalloproteinase-8 (MMP-8) has been identified as major tissue-destructive enzyme in periodontal disease. MMP-8 is released from neutrophils in a latent, inactive pro form and becomes activated during periodontal inflammation by independent and/or combined actions of host-derived inflammatory mediators .C-reactive protein is a systemic marker released during the acute phase of an inflammatory response. Subjects, materials and methods: Total samples
