OBJECTIVES To investigate the combined roles of level and perceived stability of self-esteem in prospectively predicting depression. DESIGN Symptoms of depression and anxiety were measured both before and after psychoeducational treatment for depression; level and perceived stability of self-esteem were measured before treatment. METHOD Participants were 26 adults (16 female), age range 21-...

This study examined narrative identity in 2 groups of participants who were younger (ages ranging from late adolescence through young adulthood) and older (over the age of 65 years). Participants completed an extensive interview in which they reported three self-defining memories. Interviews were coded for several characteristics of autobiographical reasoning: self-event connections representin...

Inhibition of Mek/Erk signaling by pharmacological Mek inhibitors promotes self-renewal and pluripotency of mouse embryonic stem cells (ESCs). Intriguingly, Erk signaling is essential for human ESC self-renewal. Here we demonstrate that Erk signaling is critical for mouse ESC self-renewal and genomic stability. Erk-depleted ESCs cannot be maintained. Lack of Erk leads to rapid telomere shorteni...

We study equilibrium shapes, stability and possible bifurcation diagrams of fluids in higher dimensions, held together by either surface tension or self-gravity. We consider the equilibrium shape and stability problem of self-gravitating spheroids, establishing the formalism to generalize the MacLaurin sequence to higher dimensions. We show that such simple models, of interest on their own, als...

OBJECTIVE This randomized controlled trial aimed to compare the stability of mandibular arch orthodontic treatment outcomes between passive self-ligating and conventional systems during 6 months of retention. METHODS Fortyseven orthodontic patients with mild to moderate crowding malocclusions not requiring extraction were recruited based on inclusion criteria. Patients (mean age 21.58 ± 2.94 ...

We address the generalized thermodynamics and the collapse of a system of self-gravitating Langevin particles exhibiting anomalous diffusion in a space of dimension D. This is a basic model of stochastic particles in interaction. The equilibrium states correspond to polytropic configurations similar to stellar polytropes and polytropic stars. The index n of the polytrope is related to the expon...

OBJECTIVES The purpose of this study was to investigate the independent relationship between neighborhood context (characterized through age structure, economic conditions, service provision, and residential stability) and self-reported health among elders in one U.S. city. METHODS By using multilevel statistical models, we examined the cross-sectional relationships between markers of neighbo...

Objective. This study aimed to evaluate effects of type 1 diabetes mellitus and mini-implant placement method on the primary stability of mini-implants by comparing mechanical stability and microstructural/histological differences. Methods. After 4 weeks of diabetic induction, 48 mini-implants (24 self-tapping and 24 self-drilling implants) were placed on the tibia of 6 diabetic and 6 normal ra...
