Intramolecular conversions. V. Rational rate constants for reversible unimolecular reactions

International Journal of Chemical Kinetics, 1985
AbstractThe available RRKM programs which cover the full pressure range (high → low‐pressure limits) were written for nonreversible reactions. For reversible reactions the correct shapes of the fall‐off curves can be estimated by applying a correction factor to the RRKM bimolecular rate constant, which depends on a ratio of state densities at the ...

Rational Vaccine Design by Reverse & Structural Vaccinology and Ontology

2021
Vaccination is one of the most successful public health interventions in modern medicine. However, it is still challenging to develop effective vaccines against many infectious diseases such as tuberculosis, HIV, and malaria. There are challenges in integrating the high volume, variety, and variability of vaccine-related data and rationally designing ...

Rational Design of a Reversible pH-Responsive Switch for Peptide Self-Assembly

Journal of the American Chemical Society, 2006
Peptide TZ1H, based on the heptad sequence of a coiled-coil trimer, undergoes fully reversible, pH-dependent self-assembly into long-aspect-ratio helical fibers. Substitution of isoleucine residues with histidine at the core d-positions of alternate heptads introduces a mechanism by which self-assembly is coupled to the protonation state of the ...

On possible reversible changes between arational and rational behavior of society

The Bulletin of Mathematical Biophysics, 1968
In our recent book,Looking at History Through Mathematics (MIT Press, 1968), we discussed two possible mechanisms of a transition of a society from an “arational” behavior, in which most things are accepted uncritically on faith, to a rational behavior, characterized by a critical appraisal of everything.

Reversed Enantioselectivity of Diisopropyl Fluorophosphatase against Organophosphorus Nerve Agents by Rational Design

Journal of the American Chemical Society, 2009
Diisopropyl fluorophosphatase (DFPase) from Loligo vulgaris is an efficient and robust biocatalyst for the hydrolysis of a range of highly toxic organophosphorus compounds including the nerve agents sarin, soman, and cyclosarin. In contrast to the substrate diisopropyl fluorophosphate (DFP) the nerve agents possess an asymmetric phosphorus atom, which ...

Why Rational People Do IrRAtIonaL tHinGs: The Theory of Psychological Reversals

Journal of Psychosocial Nursing and Mental Health Services, 1991
1. The theory of psychological reversals holds that individuals are inherently inconsistent and that they reverse between metamotivational states. Four pair states have been identified: telic/paratelic; negativistic/conformist; mastery/sympathy; autocentric/allocentric. 2.

Rational Design of Potent Non-Nucleoside Inhibitors of HIV-1 Reverse Transcriptase

Journal of Medicinal Chemistry, 2012
A new series of non-nucleoside reverse transcriptase inhibitors based on an imidazole-amide biarylether scaffold has been identified and shown to possess potent antiviral activity against HIV-1, including the NNRTI-resistant Y188L mutated virus. X-ray crystallography of inhibitors bound to reverse transcriptase, including a structure of the Y188L RT ...
