Genome‐wide analysis of in vivo CcpA binding with and without its key co‐factor HPr in the major human pathogen group A Streptococcus

Molecular Microbiology, Volume 115, Issue 6, Page 1207-1228, June 2021., 2021
The carbon catabolite protein, CcpA, regulates carbohydrate utilization and virulence in concert with its phosphorylated co‐factor histine containing protein (HPr~P). In this study we engineered a CcpA isoform that does not interact with HPr~P.

Equivalence of finite dimensional input-output models of solute transport and diffusion in geosciences [PDF]

, 2016
We show that for a large class of finite dimensional input-output positive systems that represent networks of transport and diffusion of solute in geological media, there exist equivalent multi-rate mass transfer and multiple interacting continua ...

Universal Evolutionary Model for Periodical Species

Complexity, Volume 2021, Issue 1, 2021., 2021
Real‐world examples of periodical species range from cicadas, whose life cycles are large prime numbers, like 13 or 17, to bamboos, whose periods are large multiples of small primes, like 40 or even 120. The periodicity is caused by interaction of species, be it a predator‐prey relationship, symbiosis, commensalism, or competition exclusion principle ...

Conservation applications of niche modeling: Native and naturalized ferns may compete for limited Hawaiian dryland habitat. [PDF]

Appl Plant Sci
Abstract Premise Competition from naturalized species and habitat loss are common threats to native biodiversity and may act synergistically to increase competition for decreasing habitat availability. We use Hawaiian dryland ferns as a model for the interactions between land‐use change and competition from naturalized species in determining habitat ...

Modelamiento molecular y análisis estructural de la variante I684S en la enzima TYK2 y su relación con la propensión a la psoriasis

Revista de la Academia Colombiana de Ciencias Exactas Físicas y Naturales, 2023
La psoriasis es una enfermedad inflamatoria crónica inmunomediada en la que el eje IL-23/Th17 dirige el proceso patogénico. En la regulación del sistema inmunitario la propensión al desarrollo de la psoriasis en una población colombiana se asoció con la ...

Remotely Almost Periodic Solutions of Ordinary Differential Equations

Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021
In this paper, we analyze the existence and uniqueness of remotely almost periodic solutions for systems of ordinary differential equations. The existence and uniqueness of remotely almost periodic solutions are achieved by using the results about the exponential dichotomy and the Bi‐almost remotely almost periodicity of the homogeneous part of the ...
