Although both the T and B cells of the Lewis rat have immunoglobulin receptors for basic protein (BP) of myelin, and both cell types are required for antibody production to BP, the present results demonstrate that the T cells are the only cells required for the induction of experimental allergic encephalomyelitis (EAE). Both EAE and anti-BP were readily induced in thymectomized, irradiated Lewi...

The Lewis blood group system comprises two main carbohydrate antigens, Le(a) and Le(b). Lewis typing has traditionally been based on serologic determinations using erythrocytes and saliva. Several recent studies have demonstrated that erythrocyte Lewis phenotype may change during pregnancy or disease, and inappropriate Lewis antigens have been found in both normal and neoplastic tissue. To eval...

Frustrated Lewis pair (FLP) chemistry, a concept that has emerged in the last decade, presents unique systems capable of metal-free hydrogenation by using simple combinations of cooperative main group element components. This finding is particularly interesting given that hydrogenation is a chemical reaction that is performed on a huge scale worldwide with current technologies relying on metal-...

Bis- and tris-Lewis acids, based on alkynylsilanes with terminal boron functions, were prepared tested for their ability to accept neutral Lewis base molecules.

The legacy of Gilbert Newton Lewis (1875-1946) pervades the lexicon of chemical bonding and reactivity. The power of his concept of donor-acceptor bonding is evident in the eponymous foundations of electron-pair acceptors (Lewis acids) and donors (Lewis bases). Lewis recognized that acids are not restricted to those substances that contain hydrogen (Brønsted acids), and helped overthrow the "mo...

Cell rolling is an important physiological and pathological process that is used to recruit specific cells in the bloodstream to a target tissue. This process may be exploited for biomedical applications to capture and separate specific cell types. One of the most commonly studied proteins that regulate cell rolling is P-selectin. By coating surfaces with this protein, biofunctional surfaces th...

©AsiaPacific MediaEducator Issue No.11 July Dec. 2001 T paper discusses some fundamental assumptions about pluralism in the Australian print media. Pluralism, the number of print media outlets available to the public, and known as structural diversity, can be considered as one of two elements of media diversity. The other is the variety of views presented by those outlets, known as content dive...

Capillary endothelial cells can be induced to form capillary-like structures in vitro by plating on fibronectin-coated dishes (Ingber, D. E., and Folkman, J. (1989) J. Cell Biol. 109, 317-330), thereby mimicking angiogenesis. To assess the role of glycoproteins bearing asparagine-linked oligosaccharides in this process, we tested the effect of oligosaccharide processing inhibitors on the format...
