Chicken egg yolk antibodies (IgY) against camel immunoglobulins were generated and their specificity was shown by double immunodiffusion, immunoelectrophoresis, and Western blotting. Anti camel antibodies specifically react to camel antibodies in immunodiffusion and immunoelectrophoresis were demonstrated. Western blotting revealed that IgY antibodies recognize the heavy chain in a number of ma...

Representatives of two species, the chicken and the goat, were immunized by injection with Freund's adjuvant, of specific precipitates prepared from the antisera of rabbits with various allotypic specificities. The precipitation reactions of the resulting antisera with normal rabbit sera were studied in liquid and in gellified media. In these reactions the isotypic specificity and often one or ...

We initiated a clinical trial for patients with advanced malignant melanoma treated with an anti-idiotype antibody that mimics the disialoganglioside GD2. We report the clinical and immune responses of the first 12 patients entered into this trial. Patients received 1-, 2-, 4-, or 8-mg doses of the anti-idiotype antibody mixed with 100 microg of QS-21 adjuvant every other week, four times, and ...

Trigallium heptachloride, G a3Cl7, has been prepared from GaCl3 and Ga in sealed glass ampoules. G a3Cl7 crystallizes in the space group P«a2, (No. 33) with a = 1181.8(1) pm; b = 889.7(1) pm; c — 1057.5(1) pm; Z = 4. The compound is isotypic with KGa2Cl7. The G a2Cl7~ anion has nearly C2 symmetry (gauche conformation) with d (G a—Clbrjdg) = 230.3 pm, d(G a—Clterm) = 214.3 pm and < G a —Cl —Ga =...

The crystal structure of the title compound, [YbCl2(H2O)6]Cl, was determined at 110 K. Samples were obtained from evaporated aceto-nitrile solutions containing the title compound, which consists of a [YbCl2(H2O)6](+) cation and a Cl(-) anion. The cations in the title compound sit on a twofold axis and form O-H⋯Cl hydrogen bonds with the nearby Cl(-) anion. The coordination geometry around the m...

The main goal is to study the Hopf algebra structure on quivers. The main result obtained by C. Cibils and M. Rosso is improved. That is, in the case of infinite dimensional isotypic components it is shown that the path coalgebra kQ admits a graded Hopf algebra structure if and only if Q is a Hopf quiver. All nonisomorphic point path Hopf algebras and point co-path Hopf algebras are found. The ...

In the title compound, [Ni(C(12)H(9)O(2))(2)(C(7)H(6)N(2))(2)]·H(2)O, The Ni(II) cation is located on a twofold rotation axis and is six-coordinated in a distorted NiN(2)O(4) octa-hedral geometry. The asymmetric unit consists of a nickel(II) ion, one 2-(naphthalen-1-yl)acetate anion, a neutral benzotriazole ligand and one half of a lattice water mol-ecule. The crystal packing is stabilized by O...

In the centrosymmetric binuclear title complex, [Dy(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Dy(III) ions are linked by four 2-phen-oxy-propionate (L) groups through their bi- and tridentate bridging modes. Each Dy(III) ion is nine-coordinated by one 1,10-phenanthroline mol-ecule, one bidentate carboxyl-ate group and four bridging carboxyl-ate groups in a distorted DyN(2)O(7) monocapped ...

We summarize here the main characteristics of a novel model of pulmonary hypersensitivity. Mice were immunized with a subcutaneous implant of a fragment of heat solidified chicken egg white and 14 days later challenged with ovalbumin given either by aerosol or by intratracheal instillation. This procedure induces a persistent eosinophilic lung inflammation, a marked bone marrow eosinophilia, an...

The title salt, (C5H6ClN2)2[CoCl4], was synthesized by slow evaporation of an aqueous solution at room temperature. The asymmetric unit consists of two essentially planar (C5H6ClN2)(+) cations [maximum deviations = 0.010 (3) and 0.014 (3) Å] that are nearly perpendicular to each other [dihedral angle = 84.12 (7)°]. They are bonded through N-H⋯Cl hydrogen bonds to distorted [CoCl4](2-) tetra-hed...
