Transition, alteration of a physical system from one state, or condition, to another.
In one type of transition, alteration in the parameters that characterize the regulatory network interactions (e.g., by mutation) can change the landscape topography: flattening a hill here, deepening a valley there, etc., thereby influencing the course of the gravity-defined trajectories of the ball/cells.
These changes impinge on the cellular transcriptome by regulating the activity of several chromatin modifying enzymes that bring about epigenomic transition through alteration in DNA methylation and histone post translational modifications.
Third, he contrasted dynamic transitions or alterations with dynamic permanence, and thus for the first time identifies, and differentiates between, two basic 'Gestalts' or forms of dynamicity.
Opportunities for ecological intensification, utilizing trees in agricultural landscapes, vary along stages of a tree cover transition of forest alteration and deforestation followed by agroforestation.
For the first transition, a typical alteration of spatiotemporal and kinematic measures can be seen in Fig. 4B,C,E,G and Fig. 5A,B,N.
It is clear that pronounced molecular alterations occur during the normal to DCIS transition; however, genetic alterations to explain the divergent gene expression patterns between in situ and invasive breast carcinomas have not been observed [ 25].
Hematopoietic pre-B-cell leukemia transcription factor interacting protein promotes GC cell proliferation through activation of G1/S and G2/M cell cycle transitions, accompanied by alteration of expression of important cell cycle regulators.
Mitochondria comprise a target of NO and there is accumulating evidence that inhibition of respiration may contribute to the pro-apoptotic effect of NO by ΔΨm alteration, transition-pore opening and release of cytochrome c [ 45, 49].
Physiological change in the menopausal transition will cause many alterations in hormonal, physical and emotional aspects of life, but it is not the cause of every symptom in a woman past 40.
In addition, the glass transition temperatures were little alteration, while the modulus maintained high value, and the impact strength was enhanced by 2 3 times compared with that of the neat epoxy.
