Background & Aim: The American Psychiatrists Association has inserted Internet gaming disorder into Section III of DSM-V. The IGD-20 test has been introduced as a tool for investigating IGD. This study aims to assess the validity of the Persian version of IGD-20 test. Methods: In this methodological study, 394 undergraduate students of Tabriz University of Medical Sciences were included using ...
Objective: Previous research has shown that attentional bias towards game-related stimuli is a significant factor in the etiology, maintenance and severity of Internet Gaming Disorder (IGD). Therefore, interventions targeting attentional bias towards game-related stimuli, can potentially ameliorate this disorder. The aim of the present research was to examine the effectiveness of online Attenti...
IgD myeloma is very rate. It differs from multiple myeloma of other classes in several aspects and its laboratory diagnosis may be difficult, as total plasma protein concentration is often normal, and a paraprotein peak may not be easily demonstrable by the conventional electrophoretic techniques. We report here two cases of IgD myeloma investigated in this laboratory. Immunochemical, biochemic...
Introduction: Host immune responses are considered as an an important factor concerning the progression of HBV infection. B cells population following Hepatitis B infection has received scant attention. A Poroliferation-Inducing Ligand (APRIL) can be introduced as a stimulator of B cell activities. Therefore, this study intended to investigate the proportion of IgD positive B lymphocytes in liv...

Recent discoveries of IgD in ancient vertebrates suggest that IgD has been preserved in evolution from fish to human for important immunological functions. A non-canonical form of class switching from IgM to IgD occurs in the human upper respiratory mucosa to generate IgD-secreting B cells that bind respiratory bacteria and their products. In addition to enhancing mucosal immunity, IgD class-sw...
Haemophilus influenzae type b and nontypeable H. influenzae have been reported to bind human immunoglobulin D (IgD). IgD myeloma sera from five patients were tested for the ability of IgD to bind to H. influenzae. Serotype b strains bound human IgD in four of the five sera tested. IgD in the fifth serum bound strongly to type b strain MinnA but poorly to other type b strains. Additionally, IgD ...
IgD is a surface immunoglobulin, which is coexpressed with IgM on greater than 90% of mature B cells, but its levels in serum are extremely low compared to those of IgM. It role as a surface receptor has been reemphasized by our recent findings that IgD receptors are induced on helper T cells by exposure to IgD and that such cells have immunoaugmenting properties. The present study shows that c...
High titers of autoantibodies directed to isotypic determinants of IgD were produced by inoculation of syngeneic monoclonal IgD, conjugated covalently to keyhole limpet hemocyanin, into adult or neonatal inbred mice. Anti-idiotypic antibodies were induced at the same time. The average affinity of the mouse antibodies (Ka approximately equal to 10(7) M-1) is similar to that of rabbit anti-IgD an...
Incubation of normal mouse splenic lymphocytes with dimeric mouse IgD results in the formation of T-cell factors that selectively inhibit rosette formation of Fc delta receptor-positive lymphocytes with IgD-coated erythrocytes. The rosette-inhibiting factors bound to IgD-Sepharose and were recovered by elution at acid pH. The results indicate that the rosette-inhibiting factors are IgD-binding ...
