Reversible covalent bonding is often used for the creation of novel supramolecular structures, multi-component assemblies and sensing ensembles. Despite the remarkable success of dynamic covalent systems, the reversible binding of a mono-alcohol with high strength is challenging. Here, we show that a strategy of carbonyl activation and hemiaminal ether stabilization can be embodied in a four-co...

Binding of the lipoteichoic acids of Bifidobacterium bifidum to human colonic epithelial cells appeared to be specific, reversible, and cell concentration and time dependent. A single population of approximately 8.3 X 10(8) binding sites per cell was detected, with a dissociation constant of 125 microM. Ester-linked fatty acids are essential for binding.

quantum-dot cellular automata (qca) is an emerging and promising technology that provides significant improvements over cmos. recently qca has been advocated as an applicant for implementing reversible circuits. however qca, like other nanotechnologies, suffers from a high fault rate. the main purpose of this paper is to develop a fault tolerant model of qca circuits by redundancy in hardware a...

introduction: several supra spinal areas such as rostral ventrolateral medulla (rvlm) area are involved in basic cardiovascular regulation. the kolliker— fuse nucleus (kf) is located in pons and is heavily connected with rvlm. the cardiovascular effect of kf nucleus has been shown and it is suggested that kf is involved in sympathetic vasomotor tone and basic cardiovascular regulation. therefor...

Phase-change materials (PCMs) undergo a reversible transition from semiconducting to metallic state, nicely termed “incipient metal.” This is driven by Peierls distortion. A model of covalent bonding developed in tight-binding scheme that accounts for the drastic evolution some properties PCMs, among which Grüneisen parameter. The original vibrational PCM and related distorted are analyzed. thr...

Supramolecular binding motifs are increasingly employed in the design of biomaterials. The ability to rationally engineer specific yet reversible associations into polymer networks with supramolecular chemistry enables injectable or sprayable hydrogels that can be applied via minimally invasive administration. In this review, we highlight two main areas where being used drug delivery systems: e...

We describe the binding of [125I]iodophenpropit, the first radiolabelled histamine H3-antagonist, to ratcortex membranes. The binding of [125I]iodophenpropit was selective, saturable, readily reversible, and of high affinity (Ko-value of 0.32 nM; Bmax-value of 209 fmoVmg of protein). Specific binding at a concentration of 0.3 nM accounted for 45 to 55% of total binding. [125I]Iodophenpropit...

11 C-SCH442416 was reported in preclinical studies with rodents and primates to be the first nonxanthine radioligand suitable for the in vivo imaging of adenosine A2A receptors with positron emission tomography (PET). The aim of the present work was to investigate the suitability of 11 CSCH442416 for the in vivo quantification of A2A receptors in human brain. Methods: Five male healthy subjects...
