the aim of this research was determination of nutritive value of cressa cretica with gas test method, in vivo digestibility and degradability with nylon bag method in three phenological stages. the amount of crude protein decreased significantly in seeding stage. but the amount of ndf and adf increased in seeding stage. the degradability of dry matter and rapid and slowly degradable fractions d...

We propose a physical model for developmental process at cellular level to discuss the mechanism of epigenetic landscape. In our simplified model, a minimal model, the network of the interaction among cells generates the landscape epigenetically and the differentiation in developmental process is understood as a self-organization. The effect of the regulation by gene expression which is a key i...

Triptycenes have been established as unique scaffolds because of their backbone ?-structure with a propeller-like shape and saddle-like cavities. They are some the key organic molecules that extensively studied in polymer chemistry, supramolecular chemistry material science. become chiral when substituents unsymmetrically attached at least two different aromatic rings. This Minireview highlight...

Directed differentiation of stem cells offers a scalable solution to the need for human cell models recapitulating islet biology and T2D pathogenesis. We profiled mRNA expression at 6 stages of an induced pluripotent stem cell (iPSC) model of endocrine pancreas development from 2 donors, and characterized the distinct transcriptomic profiles associated with each stage. Established regulators of...

Vacuolar processing enzyme (VPE) is a Cys proteinase responsible for the maturation of vacuolar proteins. Arabidopsis thaliana deltaVPE, which was recently found in the database, was specifically and transiently expressed in two cell layers of the seed coat (ii2 and ii3) at an early stage of seed development. At this stage, cell death accompanying cell shrinkage occurs in the ii2 layer followed...

If we can construct an information-processing system with rules of behavior that lead it to behave like the dynamic system we are trying to describe, then this system is a theory of the child at one stage of the development. Having described a particular stage by a program, we would then face the task of discovering what additional information-processing mechanisms are needed to simulate develo...

introduction: determining the skeletal age and remaining growth potential of patients are important factors in orthodontic treatment. evaluating cervical vertebrae development is a reliable method for determining skeletal age. this study aimed to evaluate the correlation between dental calcification and stages of skeletal maturation. materials and methods: this descriptive cross-sectional study...

in this study the relation between cultural development and social development in i an is studied with secondary analysis method. statistical data of this study is based on previous experimental researches, especially national survey of iranians cultural behaviors in 1378 and national surveys of iranians values and attitudes in 1379 and 1382. for measuring the cultural development, some element...
