An ultrasensitive and renewable electrochemiluminescence (ECL) immunosensor was developed for the detection of tumor markers by combining a newly designed trace tag and streptavidin-coated magnetic particles (SCMPs). The trace tag (RuL@SiO(2)-Au~RuL-Ab2) was prepared by loading Ru(bpy)(3)(2+)(RuL)-conjuged secondary antibodies (RuL-Ab2) on RuL@SiO(2) (RuL-doped SiO(2)) doped Au (RuL@SiO(2)-Au)....

OBJECTIVES In line with a recent report entitled Effective Use of Educational Technology in Medical Education from the Association of American Medical Colleges Institute for Improving Medical Education (AAMC-IME), this study examined whether revising a medical lecture based on evidence-based principles of multimedia design would lead to improved long-term transfer and retention in Year 3 medica...

Freund's adjuvant (FA) and TiterMax (TM) were compared for their effectiveness in the induction of the anti-idiotypic antibodies (anti-Id or Ab2) in pigs, goats and mice against swine polyclonal anti-pseudorabies virus (PRV) antibodies (Ab1) by sequential immunization procedures. Both adjuvants had similar effects on inducing anti-swine immunoglobulin antibodies in the animals. However, high le...

The general overexpression of p53 by different types of tumor cells suggests that p53 immunity might be generally useful for tumor ininiunotherapy. We describe here the induction of immunity to p53 and resistance to tumor metastasis using an idiotypic network. Mice were immunized with domain-specific anti-p53 monoclonal antibodies (Abl): PAb-248 directed to the N-terminus; PAb-246 directed to t...

Affinity-purified rabbit antibodies specific for collagen types I, III, AB2 and for a partially characterized type IV collagen derived from a murine tumor were used to study the distribution of collagens in the normal mouse kidney. Immunofluorescence staining of conventional frozen sections demonstrated that types I and III were present in bundles around large vessels and in fibers surrounding ...

By immunization of mice with the anti-CA 125 monoclonal antibody OC125, we tried to induce antibodies directed against the tumour-associated antigen CA125, via activation of the idiotypic network. Mice immunized by repeated administrations of F(ab')2-fragments of the OC125 antibody produced anti-idiotypic antibodies, imitating the original target antigen of the OC125. After induction of these a...

Anti-idiotypic antibodies (Ab2) were raised in allotype-matched rabbits against anti-carbohydrate or anti-tobacco mosaic virus antibodies (Ab1). Several Ab2 were purified and injected into a third series of rabbits III which synthesized antiantiidiotypic antibodies (Ab3). Antigen was then given for the first time in those rabbits who had synthesized Ab3. The specific antibody synthesized in rab...

Atiyah and Bott ([AB1],[AB2]) generalized this theorem to complexes of elliptic operators; we briefly recall (under mild restrictions) their theorem. Let E0, E1, · · · , EN be a sequence of smooth hermitian vector bundles over M , equipped with a sequence of first order differential operators Di : Γ(Ei) → Γ(Ei+1). This sequence, denoted Γ(E), is called an elliptic complex if for all i, Di+1Di =...

High-fat meals (HFM) induce metabolic stress, leading to the activation of protective mechanisms, including inflammation and endogenous antioxidant defences. In the present study, we investigated the effects of antioxidant-rich fruit juice drinks on the endogenous antioxidant response induced by HFM. In a double-blind, cross-over design (10 d washout), fourteen overweight volunteers were random...
