TRPA1: the species difference
provided a comprehensive review on the recent progress and remaining puzzles. Ample evidence suggests that the sensory function of TRPA1 is evolutionarily conserved. This notion is further supported by the fact that TRPA1 from several mammalian species (human, rat, and mouse) is activated by common ligands (a plethora of electrophylus) through a common mechanism (covalent modification). However...
متن کاملRepresentational difference analysis to distinguish cryptic species.
In the study of biodiversity it is important to have a reliable system for identification of various genetically distinct units (species, subspecies, etc.). One of the most efficient tools available today is the polymerase chain reaction (PCR) with diagnostic primers that yield a detectable product for one taxon but not for other taxa. Critical to this method is the identification of diagnostic...
متن کاملSpecies and Cell Types Difference in Tryptophan Metabolism
L-Tryptophan (L-TRP) is a nutritionally essential amino acid and the kynurenine (KYN) pathway is the major route of L-TRP catabolism. Besides being synthesized for proteins, L-TRP and its metabolites have critical roles for the functions of nervous and immune systems. Many researches show that optimal amounts of L-TRP in diets depend on species, developmental stages, environmental factors and h...
متن کاملFeedback Control in a Periodic Delay Single-Species Difference System
A periodic delay single-species difference system with feedback control is established. With the help of analysis method and Lyapunov function, a good understanding of the permanence and global attractivity of the system is gained. Numerical simulations are presented to verify the validity of the proposed criteria. Our results show that feedback control has no influence on the permanence while ...
متن کاملIntegro-difference equations for interacting species and the Neolithic transition
We introduce a set of sequential integro-difference equations to analyze the dynamics of two interacting species. Firstly, we derive the speed of the fronts when a species invades a space previously occupied by a second species, and check its validity by means of numerical random-walk simulations. As an example, we consider the Neolithic transition: the predictions of the model are consistent w...
