چکیده

thinking would result in increased diabetes-related goal setting. Goals during the late adolescent period would be developmentally appropriate, such as self-managing their diabetes in order to spend more time away from home with peers. However, what goals are set throughout the stages of adolescence remains unstudied. Risk and Protective Factors Health status and individual factors often influence diabetes self-management behaviors and can serve as either risk or protective factors (Knafl, Grey & McCorkle, 2006). The uniqueness and complexities of self management are influenced by many things including. The medical regimen followed, duration of illness and gender. However, there are few studies, to date, with a focus on regimen and duration of illness. Although the affect gender has on self-management has been widely studied, the findings from studies are

Negative guidance factor-induced macropinocytosis in the growth cone plays a critical role in repulsive axon turning.

Macropinocytosis is a type of poorly characterized fluid-phase endocytosis that results in formation of relatively large vesicles. We report that Sonic hedgehog (Shh) protein induces macropinocytosis in the axons through activation of a noncanonical signaling pathway, including Rho GTPase and nonmuscle myosin II. Macropinocytosis induced by Shh is independent of clathrin-mediated endocytosis bu...

Syntaxin 1B suppresses macropinocytosis and semaphorin 3A-induced growth cone collapse.

Growth cone collapse is a crucial process for repulsive axon guidance and is accompanied by a reduction in growth cone surface area. This process of reduction may be regulated by endocytosis; however, its molecular mechanism is unclear. Macropinocytosis is a clathrin-independent form of endocytosis in which large areas of plasma membrane can be engulfed. We have reported previously that macropi...

Ca2+ induces macropinocytosis via F-actin depolymerization during growth cone collapse.

Growth cone collapse occurs in repulsive axon guidance and is accompanied by a reduction in the surface area of the plasma membrane of growth cones. However, the mechanism of this reduction is unclear. Here, we show that during growth cone collapse, caffeine-induced Ca(2+) release from ryanodine-sensitive Ca(2+) stores triggers the formation of large vacuoles in growth cones by macropinocytosis...

Sonic Hedgehog Guides Axons via Zipcode Binding Protein 1-Mediated Local Translation.

Sonic hedgehog (Shh) attracts spinal cord commissural axons toward the floorplate. How Shh elicits changes in the growth cone cytoskeleton that drive growth cone turning is unknown. We find that the turning of rat commissural axons up a Shh gradient requires protein synthesis. In particular, Shh stimulation increases β-actin protein at the growth cone even when the cell bodies have been removed...

Performance of methylation and expression fluctuations of sonic hedgehog genes in gastric adenocarcinoma

Gastric cancer (GC) is considered as one of the most serious cancers, and in Iran, due to environmental factors in different regions, it has a high frequency. Apart from environmental factors, genetic and epigenetic ones also play a key role in the development of carcinogenesis of GC. In this regard, the study of functioning of the molecular mechanisms involved in the carcinogenesis and also tu...
