Current advances in molecular biology enable us to access the rapidly increasing body of genetic information. It is still challenging to model gene systems at the molecular level. Here, we propose two types of reaction kinetic models for constructing genetic networks. Time delays involved in transcription and translation are explicitly considered to explore(More)
A stochastic genetic toggle switch model that consists of two identical, mutually repressive genes is built using the Gillespie algorithm with time delays as an example of a simple stochastic gene regulatory network. The stochastic kinetics of this model is investigated, and it is found that the delays for the protein productions can highly weaken the(More)
Memantine hydrochloride is a first-line therapeutic drug approved by the US Food and Drug Administration for the management of moderate to severe Alzheimer's disease (AD). We conducted a review of the literature to determine the changes to the central glutamatergic neurotransmitter system in dementia subtypes and the available clinical evidence regarding(More)
A microstructure design of anisotropic resonant inclusions is investigated for the elastic metamaterial plate with the aid of the numerically based effective medium model. Experimental validation is then conducted in the anisotropic metamaterial plate through both harmonic and transient wave testing, from which the anisotropic effective dynamic mass(More)
To study noise in the number of protein molecules produced in gene expression, we use a delayed reaction model coupling transcription and translation to examine nine biochemical factors. Fourteen numerical experiments were performed, which show clearly the linear scaling behavior between the protein variance and the mean. We found that the most dominant(More)
BACKGROUND The RNA binding protein, DEAD END (DND1), is essential for maintaining viable germ cells in vertebrates. It is also a testicular germ cell tumor susceptibility factor in mice. DND1 has been shown to interact with the 3'-untranslated region (3'-UTR) of mRNAs such as P27 and LATS2. Binding of DND1 to the 3'-UTRs of these transcripts blocks the(More)
The Jesse H. Jones Graduate School of Management was established in 1974 through a gift from Houston Endowment, Inc. The school provides its highly select graduate students with unique opportunities for professional training in management. The master of business administration (MBA) program includes elective offerings in accounting , entrepreneurship,(More)
The increasing evidences showed that adverse early life events have profound long lasting consequences in adult rats including neural, behavioral, and cognitive effects. Early maternal separation was one of the models of adverse early life stress, but which period acts critically was unknown until now. The purpose of this paper was to explore the effects of(More)
