Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease of central nervous system with complex etiopathogenesis that impacts young adults (Lee et al., 2015), and MS impacts younger and middle aged character and leads to a range of disabilities that can alter their daily routines (Yara et al, 2010). Although, the exact cause of MS is still undetermined, the disease is mediated by adaptive immunity through the infiltration of T cells into the central nervous system (Bjelobaba et al, 2017). MS causes the Focal neurological symptomsand biochemical changes in the molecular level and the variation of neural cells such as loss or alteration of sensation, motor function, visible signs such as blurred vision or transient blindness, disturbance of conjugate eye movements, bladder and bowel dysfunction and cognitive impairment (Induruwa et al, 2012 and Jafarzadeh et al, 2014). Autoimmune diseases (ADs) are chronic conditions initiated by way of the loss of immunological tolerance to self-antigens (TodorovicDilas et al, 2011). It is a heterogeneous group of disorders in which more than one modification in the immune system can be specific to a particular tissue or organ or might also be systemic, non-specific, involving multiple tissues or organs (Ray et al, 2012). One possible cause behind this is a lack of understanding of pathogenic mechanisms driving progressive multiple sclerosis. Due to the indolent nature of symptom progression, current disease criteria used to signify the course of disease (Lublin et al, 2014) indicate diagnosis is generally retrospective and based totally on history of gradual worsening. Clearly, diagnosis is primary based on clinical judgment, as there is no fully reliable diagnostic test (Ontaneda et al, 2015). In latest years, the elements involved in the etiology of the disease have also included oxidative stress (OS), which is described as an imbalance between the generation of reactive oxygen species (ROS) and the mechanisms that are responsible for their elimination, andthe imbalance between OS agents and antioxidants leads to OS activating the inflammatory process (Phaniendra et al, 2015). In the absence of enough antioxidant defenses, ROS can reason oxidative damage to macromolecules resulting in oxidation of lipids, proteins and deoxyribonucleic acid (DNA) (Griffiths, 2002). Some reseach report that ROS play a main role in myelin phagocytosis (Ghabaee et al, 2010 and Tasset et al, 2012). The inflammatory response gives rise to the manufacturing of both ROS and Reactive Biochem. Cell. Arch.

Aim of study The aim of this study focuses on determination 8-H2-dG, MDA and PON1 in multiple sclerosis disease and finds the relationship between newly marker 8-H-2-dG with MDA and PON1. MATERIALS AND METHODS Subjects This study was performed on 25 female patients with age (25-35) years who diagnosed by physicians as a multiple sclerosis in Misan governorate. The patients compared with 25 apparently healthful in the identic rangel of age. In this study sample was collected five mL of venous bloods, placed in to plain tubes until coagulation was performed. Serum was separated from blood cells by centrifugation 4000 r.p.m. Assay method Determination of serum of 8-H-2-dG This assay that can be used for quantification of 8- H-2-dG in urine, cell culture, plasma and other sample matrices. The ELISA utilize an 8-H-2-dG coated plate and HRP- conjugated antibody or detection which allows for any assay range of 0.94-60 ng/mL, with sensitivity of 0.59 ng/mL. Determination of MDA The concentration of MDA,which is the consequence of lipid peroxidation and a marker of oxidative stress, was measured using thiobarbiturc acid. Determination of PON1 The quantitive sandwich enzyme immunoassay (ELISA) technique was employed for determination of PON1.
New compounds of amids [IV]a-e and Schiff bases [V]f-h derived from 2-amino-1,3,4-oxadiazoles [III] were synthesized and characterized by physical and spectraldata.2-Aamino-1,3,4-oxadiazoles was prepared by the action of bromine on acorresponding semicarbazide [II]( which was prepared by reaction of dialdehyde [I]with semicarbazide hydrochloride ) in the presence of sodium acetate , followed byan intramolecular cyclization .

In this research, cyclic compounds derived from 2- furfural mercaptan (oxazole, triazoles) were synthesized, and their biological efficacy was measured and compared with standard drugs. Also, their effectiveness as anti-oxidant was measured and compared with ascorbic acid as a standard substance. Some of the synthesized compounds were deduced with good efficacy. © 2021 Sami Publishing Company. All rights reserved

This study aimed to fabricate a curcumin@platinum nanohybrid (CUR@Pt NPs) through a green tea–based synthesis method and to evaluate its various functions, including antioxidant, burn-healing, and selective anticancer activities against PANC-1 pancreatic cancer cells. Green tea polyphenols served as natural reducing and stabilizing agents, facilitating an eco-friendly, single-step manufacturing process. Physicochemical characterization confirmed successful nanohybrid formation: a CUR@Pt band appeared at 457 nm in the UV–Vis spectrum, XRD displayed crystalline platinum peaks at 2θ = 46.9°, and 67.0°, matching the (200), and (220) planes, respectively, and TEM images showed well-dispersed spherical nanoparticles with an average siz

Background: The gene encoding a disintegrin and metalloproteinase domain 33 (ADAM33) is known to be associated with asthma in different ethnic groups. In Iraq, among the Arab ethnic background, this association has not yet been highlighted. Methods: One hundred and ninety-two asthmatics were examined; 118 males and 74 females (mean age 38.23 ± 9.13 years). The control group was 183; 110 males and the rest were females. The SNP of rs2280091 A/G (T1) was studied here to determine adam33 genotyping status using polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP). The level of total IgE was measured using enzyme-linked immunosorbent assay (ELISA). Results: Significant differences (p = 0.004) in the frequencies of

Background: Most prevalent chronic liver disease in developed and developing nations is non-alcoholic fatty liver disease. From fatty liver, which often has benign, non-progressive clinical history, to non-alcoholic steatohepatitis, a more serious variant of fatty liver that can lead to cirrhosis and end-stage liver disease, non-alcoholic fatty liver disease encompasses broad spectrum of diseases. The gold standard for determining extent of hepatic fibrosis is still liver biopsy; however, number of noninvasive tests have been established to make diagnosis and assess effectiveness of treatment.
Objective: Aim of study was to assess effectiveness of the combination of fibroscan and

Background: Traumatic ulcerative granuloma with stromal eosinophilia is an impressive benign chronic ulcerative lesion of the oral mucosa with vague etiopathogenesis. It was supposed to represent an oral counterpart of primary cutaneous CD30+ lymphoproliferative disorder. Histopathologically, it is characterized by mixed inflammatory infiltrate predominated by histiocytes, lymphocytes and eosinophils along with presence of scattered large atypical mononuclear cells. It has worrisome clinical presentation. It may heal spontaneously, but in most occasions it persists and never heal unless removed surgically (incisional or excisional biopsy). A rare subset may show worrisome immunohistochemical features. Follow up is highly recommended. Mat

Peripheral artery disease (PAD) is associated with increased oxidative stress and impaired endothelial function. Ticagrelor treatment improves antioxidant properties in addition to its antiplatelet effects. This study investigated the impact of Ticagrelor treatment on serum superoxide dismutase (SOD) levels and other biochemical parameters in PAD patients. It also evaluated the potential diagnostic accuracy and clinical utility of specific biomarkers based on receiver operating characteristic (ROC) analysis. Seventy individuals were categorized into healthy control (n=40), baseline PAD patients not on Ticagrelor (B-PAD, n=30), and same PAD patients after treated with Ticagrelor (A-PAD, n=30). Parameters measured included SOD concent
