T cell responses to myelin basic protein (MBP) are thought to play an important role in the pathogenesis of multiple sclerosis (MS). The response to the 83-99 region of MBP represents a dominant response to MBP in patients with MS and is associated with HLA-DR2 that is linked with susceptibility to MS. Although T cell clones reactive to various regions of MBP have been found to exhibit heteroge...

Normal individuals with an HLA haplotype containing either DR2, MT1, or B8/DR3 are more likely to have abnormally prolonged Fc receptor-mediated mononuclear phagocyte system (MPS) clearance of IgG-sensitized autologous erythrocytes than their normal counterparts without such haplotypes. Although measurement of Fc receptor binding by rosette formation and saturable IgG aggregate binding revealed...

The theory of PBW properties of quadratic algebras, to which this paper aims to be a modest contribution, originates from the pioneering work of Drinfeld (see [Dr1]). In particular, as we learned after publication of [EG] (to the embarrassment of two of us!), symplectic reflection algebras, as well as PBW theorems for them, were discovered by Drinfeld in the classical paper [Dr2] 15 years befor...

Flexible bronchoscopy is more and more used for diagnosis and management of various pulmonary diseases in pediatrics. As poor coordination of children, the procedure is usually performed under general anesthesia with spontaneous or controlled ventilation to increase children and bronchoscopists' safety and comfort. Previous studies have reported that dexmedetomidine (DEX) could be safely and ef...

Forty two white patients of British or Irish descent with coeliac disease and 28 with dermatitis herpetiformis were typed for class I HLA-A, B, and C, and class II DR and DQ antigens. In coeliac disease there was a significant increase in the frequencies of A1, B8, DR3, DR7, and DQw2 compared with controls but no increase of DR2. In dermatitis herpetiformis there were similarly increased freque...

Let P be a Poisson homogeneous G-space. In [Dr2], Drinfeld shows that corresponding to each p ∈ P , there is a maximal isotropic Lie subalgebra lp of the Lie algebra d, the double Lie algebra of the tangent Lie bialgebra (g, g∗) of G. Moreover, for g ∈ G, the two Lie algebras lp and lgp are related by lgp = Adg lp via the Adjoint action of G on d. In particular, they are isomorphic as Lie algeb...

One hundred and one of 146 patients presenting with isolated idiopathic optic neuritis, previously reviewed in 1978, were reassessed clinically, and retyped for HLA antigens and Factor B alleles, after a mean follow-up of 11.6 years. Fifty eight patients (57%) had developed multiple sclerosis at the time of reassessment in the present study, of whom 51 (88%) had clinically definite disease. Thi...

Fourteen individuals with complete C2 deficiency from 11 families and 3 heterozygous C2-deficient individuals from two families were investigated. In all the 24 independent C2-deficient haplotypes, the complotype S042 was present and the majority (21/24) was [HLA-B18,S042,DR2]. All carried the type I C2 deficiency C2 pseudogene with its characteristic 28 bp deletion. All but two haplotypes had ...

Narcolepsy runs in families, and recent research has revealed the human leukocyte antigen (HLA) DR2 to be a genetic marker closely associated with the disease. But, as indicated by family studies, other factors contribute to the pathogenesis of narcolepsy. The investigation of monozygotic twins is the most specific research tool for distinguishing between a multigenetic and a multifactorial pat...
