α-amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2zncl2 as a bio lewis acidic ionic liquid. mild lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.
PURPOSE Lewis rats immunized with myelin basic protein (MBP) develop experimental autoimmune encephalomyelitis (EAE) and associated anterior uveitis (AU), which recurs. The goal was to analyze cellular activation markers and adhesion molecules of T cells that infiltrate the eyes and spinal cord during acute and recurrent AU in actively and passively induced diseases simultaneously in the same a...
Norovirus (NoV), a member of the family Caliciviridae, is a major cause of acute water- and food-borne nonbacterial gastroenteritis and forms antigenically diverse groups of viruses. Human NoVs are divided into at least three genogroups, genogroups I (GI), GII, and GIV, which contain at least 15, 18, and 1 genotypes, respectively. Except for a few genotypes, all NoVs bind to histo-blood group a...
Association of Haptoglobin Phenotypes with Serum Levels of IgE and IgA in Allergic Rhinitis Patients
Background: Allergic rhinitis (AR) is an allergic disorder of the nasal tissue that underlies diseases such as sinusitis, otits and asthma. Different predisposing factors including immunological and non-immunological factors contribute to the disease pathogenesis. Objective: To investigate association of haptoglobin (Hp) phenotypes (Hp1-1, 2-1 and 2-2) with serum immunoglobulins A and E levels ...
Background: Disequilibrium between oxidative stress and antioxidant levels has been proposed as an important case of exudative age-related macular degeneration (ARMD). The aim of the present study was to investigate lipid profile and oxidized low-density lipoprotein (OX-LDL) levels within paraoxonase 1 (PON1) phenotypes together in the patients with exudative ARMD. Methods: Of 90 patients, 45 ...
ABSTRACT Alpha 1-Antitrypsin is one of the most important serine protease in human serum,inhibiting several proteases.As an inhibitor of proteases it is a non-specific lever in humoral defence of the body. Its level increases significantly under the infections condition of pregnancy. The health of lung,too, depends on maintaininig the equilibrium of protease antitrypsin ,and Alpha 1-trypsin p...
Background and Aims: Age-related macular degeneration (ARMD) is a degenerative retinal disorder that causes progressive loss of central vision in older adults. The study aimed to determine the effect of asymmetric dimethylarginine (ADMA) as oxidizing metabolite and paraoxonase (PON1) activity within its phenotypes as an antioxidant agent in the development of such multifactorial disease. Mater...
Abstract Background and Objectives The FUT3 gene regulates the expression of Lewis blood group antigens mainly Lea and Leb. The Lewis negative phenotype, is the result of an inactivated FUT3 enzyme that lacks glycosidase activity. Several single nucleotide polymorphisms (SNPs) may cause enzyme inactivation with different racial distribution. This study aimed to determine the frequency of these...
