Abstract:

The totalizing and absolutizing tendencies of metaphysics can undermine our essential ethical relationality. Is there a metaphysics that is robust enough and conducive to preserving this intuition? In answer, this paper will draw upon Martin Buber and Justus Buchler. Buber’s seminal work, I and Thou (1923), explores the nature of the ethical encounter. Buchler’s Metaphysics of Natural Complexes (1966) develops a general ontology, which can be described as an ordinal metaphysics. Encounters are thoroughly relational for Buber. Buchler’s metaphysics is also thoroughly relational. A phenomenologi

Abstract:

Innate cell engager (ICE®) constructs are bispecific tetravalent antibodies targeting specific tumor antigens and simultaneously engaging natural killer (NK) cell and macrophage receptors for the destruction of tumor cells. Pre-complexing of ICE® constructs with adoptive NK cells is a novel approach to enhance NK cell activity. The suitability of such complexes for cryopreservation, whilst retaining the biological activity and specificity, may enable the development of off-the-shelf NK cell products. This study investigates the binding affinity of ICE® constructs targeting EpCAM and NK cell re

Abstract:

Abstract This research work investigates the iron chromatographic displacement from the granular activated carbon (GAC) columns that occurred in the Vars, Ontario groundwater treatment plant. Natural organic matter (NOM) (XAD-8) fractionation showed that 30% of NOM was hydrophobic with the capability of forming complexes with iron. CHELEX-100 isolation indicated that 37–40% of the iron was organically-bound. The quantification of complexed iron performed on GAC microcolumn effluent at iron exhaustion point showed that this iron was neither adsorbed nor split from NOM. This indicates that NOM–i

Abstract:

Retinoid X receptors (RXRs) are promiscuous partners of heterodimeric associations with other members of the Nuclear Receptor (NR) superfamily. Through these liaisons RXR ligands (“rexinoids”) either transcriptionally activate on their own the “permissive” subclass of heterodimers (PPAR/RXR, LXR/RXR, FXR/RXR) or synergize with partner ligands in the “non-permissive” subclass of heterodimers (RAR/RXR, VDR/RXR and TR/RXR). The nature and extent of the interaction of the ligand-receptor complexes with co-regulators, which is cell and context-dependent, results ultimately in transcriptional modula

Abstract:

We investigate the similarities between adic finiteness and homological finiteness for chain complexes over a commutative Noetherian ring. In particular, we extend the isomorphism properties of certain natural morphisms from homologically finite complexes to adically finite complexes. We do the same for characterizations of certain homological dimensions. In addition, we study transfer of adic finiteness along ring homomorphisms, all with a view toward subsequent applications.

Abstract:

Modern food products provide no more than 5-6% of the body's need for micronutrients, many of which are antioxidants. The current state of the problem of nutritional deficiency predetermines a chronic long-term deficiency of antioxidants in the diet. Providing the body with balanced polyvalent antioxidant complexes and normalizing its antioxidant status is the basis of health and active longevity.
