emotional communication and economic factors play an important role in having a satisfying relationship and a more successful marriage. in this regard, we investigated the 10-year outcome of partners from three different economic levels regarding the relationship between emotional intelligence (ei) and marital satisfaction.the research was designed as a descriptive-correlative survey and data w...

background: the cultured mesenchymal stem cells (msc) have been used in many clinical trials however, there are still some concerns about the cultural conditions. one concern is related to the use of fbs as a widely used xenogeneic supplement in the culture system. human platelet-rich plasma (hprp) is a candidate replacement for fbs. in this study, the effect of hprp on msc proliferation and os...

BACKGROUND Autologous platelet concentrate has been used to improve the function and regeneration of injured tissues. Tendinopathies are common in clinical practice, although long-term treatment is required. On the basis of lead time, we compared the effect of using platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) in repairing rat Achilles tendon. METHODS The effectiveness of usi...

Decorin belongs to the small leucine-rich repeat proteoglycan family, interacts with fibrillar collagens, and regulates the assembly, structure, and biomechanical properties of connective tissues. The decorin-collagen type I-binding region is located in leucine-rich repeats 5-6. Site-directed mutagenesis of this 54-residue-long collagen-binding sequence identifies Arg-207 and Asp-210 in leucine...

Theories of economic development suggest variously that national income increases or decreases the propensity for states to fight, while systematic evidence of the impact of development on warfare is ambiguous or non-existent. The lack of empirical support for nominally opposing claims can be reconciled if elements of both sets of arguments are partially correct. We use a formal model to constr...

The nervous system consists of an ensemble of billions of neurons interconnected in a highly specific pattern that allows proper propagation and integration of neural activities. The organization of these specific connections emerges from sequential developmental events including axon guidance, target selection, and synapse formation. These events critically rely on cell-cell recognition and co...

We define a rich model to be one which contains a proper elementary substructure isomorphic to itself. Existence, non-structure, and categoricity theorems for rich models are proved. We show that a countable theory with few rich models is categorical in Ki. We also consider a stronger notion of richness, and in discussing it prove: "If T is an unstable theory, then for any saturated model M of ...
