Mice immunized with more SRBC than are required to produce optimal delayed-type hypersensitivity reactions, developed good antibody responses and poor delayed foot pad reactions. Cyclophosphamide treatment in low doses (20 mg/kg) before immunization, augmented the delayed-type hypersensitivity without affecting antibody responses. Cyclophosphamide did not augment delayed responses to optimal do...
Guinea pigs sensitized with either hen, duck, or goose egg albumin showed delayed hypersensitivity followed by Arthus reactions to the homologous antigen, but tended to have much weaker delayed responses and slower antibody formation to heterologous antigens. Guinea pigs with delayed hypersensitivity to one of the avian antigens had a slower antibody response to a secondary injection of heterol...
Bridged ring systems are widely found in natural products, and successful syntheses of them frequently feature intramolecular Diels-Alder reactions. These reactions are subclassified as either type I or type II depending on how the diene motif is tethered to the rest of the substrate (type I are tethered at the 1-position of the diene and type II at the 2-position). Although the type I reaction...
We are concerned here only with the last group which the Symposium defined as "those reactions to drugs in which clinical symptoms are conditioned by previous exposure to and sensitization to the drug. They are mediated by an antigen-antibody reaction". This definition, although adequate at the time of its formulation, requires some modification in the light of newer knowledge, in particular ex...
Experiments are described in which tanned red cells coated with a globulin fraction of human serum with a high titre of antibody to human thyroglobulin were agglutinated by saline extracts of human thyroid gland and thyroglobulin but not by other tissue extracts. It is suggested that the linkage is due to a specific antigen antibody reaction between cell-bound antithyroid antibody and thyroglob...
Systematic study of spallation reactions Systematic study of spallation reactions in inverse kinematics at the FRS in inverse kinematics at the FRS A campaign of measurements and studies started at GSI in 1996 in collaboration with other institutes:
An indirect enzyme-linked immunosorbent assay has been used for the detection of Salmonella group H antibodies.
(001)-oriented monoclinic nanorod and microplate WO3 films are fabricated on commercial FTO-coated glass substrates by a rubbing seed layer and a spin-coating seed layer assisted by hydrothermal reactions. The nanorod film obtained by the rubbing seed layer assisted by hydrothermal reactions is more regular and perpendicular to the substrate.
Despite its assumed importance for emotional well-being, studies investigating the positivity effect (PE) in older adults' information processing rarely tested its relationship with immediate or general affective outcome measures like emotional reactivity or emotional well-being. Moreover, the arousal level of the to-be-processed emotional stimuli has rarely been taken into account as a moderat...
