Background and Purpose—Stroke is implicated in the incidence of dementia, and the risk of poststroke dementia is well characterized, but the excess risk of dementia in those with stroke compared with those without stroke is not well known. Methods—We conducted a systematic review of the excess risk of incident dementia conferred by stroke. Studies of the risk of incident dementia in the populat...

Price rigidity is the key mechanism for propagating business cycles in traditional Keynesian theory. Yet the New Keynesian literature has failed to show that sticky prices by themselves can e¤ectively propagate business cycles in general equilibrium. We show that price rigidity in fact can (by itself) give rise to a strong propagation mechanism of the business cycle in standard New Keynesian mo...

In a wide class of monetary models with both cash and credit goods, the main welfare cost of inflation is that it distorts the choice between these two goods. In these models, distortions exist because the relevant measure of the relative price between cash and credit goods for consumers is the usual relative price discounted by the nominal interest rate. Changes in the inflation rate therefore...

OBJECTIVES/HYPOTHESIS Mesenchymal stem cells (MSCs) hold therapeutic promise for vocal fold scar, yet the precise mechanism(s) underlying tissue level changes remain unclear. We hypothesize that MSCs interact with native fibroblasts to favorably affect healing. Furthermore, we hypothesize that these interactions vary based on MSC source. METHODS Vocal fold fibroblasts (VFFs), adipose-derived ...

This paper seeks to evaluate the effects of expansionary monetary policy by the central bank on inflation, output and employment in a limited-participation model for different parameters value of inter-temporal elasticity of substitution and the Frisch (inverse of the labor supply) elasticity. To this end, a modified cash in advance model in line with Lucas (1990), Christiano (1991) and F...

This study examined the effects of antagonism of the peak level of glucocorticoids in vivo, which occurs as rats enter the feeding/activity (dark) period on glucose and glutamine metabolism in incubated isolated rat soleus muscle preparations. Thus the rats were treated with the potent glucocorticoid antagonist RU 486 2 h before and 1 and 2 h into the dark period. Both the content of glutamine ...

Background Despite the risk of ‘method slurring’, researchers have triangulated within a single qualitative study methods that are philosophically incongruent or in a limited context, are congruent, as with hermeneutic phenomenology and constructivist grounded theory. Methods/ Materials We aimed to make the case that what works best can be to mix two qualitative methods that are philosophically...

In this study, we develop a monetary Schumpeterian growth model with endogenous market structure (EMS) to explore the e¤ects of monetary policy on the number of …rms, …rm size, economic growth and social welfare. EMS leads to richer implications and di¤erent results from previous studies in which market structure is exogenous. In the short run, a higher nominal interest rate leads to lower grow...

BACKGROUND Early gestation represents a period of vulnerability to environmental insult that has been associated with adult psychiatric disease. However, little is known about how prenatal perturbation translates into adult brain dysfunction. Here, we use a longitudinal study design to examine the effects of disruption of early gestational neurogenesis on brain volume in the non-human primate. ...
