Learning and Memory in the Immune Response1
Following 1 injection of rabbits with moderate amounts of some dinitrophenylated proteins, the 7 S antibodies formed initially have low average affinity for the 2,4-dinitrophenyl (DNP) group, and appear relatively homogeneous with respect to affinity. The anti-DNP molecules formed later appear more heterogeneous in binding activity and have higher average affinity for the DNP group. The rate of...
متن کاملRadiation-induced Bystander Effect in Immune Response1
Objective Since most reports on bystander effect have been only concerned with radiation-induced damage, the present paper aimed at disclosing whether low dose radiation could induce a stimulatory or beneficial bystander effect. Methods A co-culture system containing irradiated antigen presenting cells (J774A.1) and unirradiated T lymphocytes (EL-4) was established to observe the effect of J774...
متن کاملMitochondrial DNA Mutations, Pathogenicity and Inheritance
Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...
متن کاملA Robot Model of Dynamic Appraisal and Response1
INTRODUCTION A general goal of biologically inspired robotics is to learn lessons from actual biological systems and to find applications in robot design. Neural controllers and adaptive algorithms are major tools to model, at some level of abstraction, functions, structures, and behaviors present in biological systems. This involves, of course, identifying in virtue of what biological systems ...
متن کاملPhilosophy and The Human Inheritance in a Post-Western World
The dissolution of the Western-dominated Postwar Order, and the Eurocentric myths that sustain it, presents a unique opportunity to ponder an old question posed by every new generation: How can philosophy, which Islamic and ancient Greek learning traditions have long defined as the pursuit of “wisdom,” resume its millennial civilizing role? This paper looks beyond passing political events to re...
