Purpose: The production of formulaic expressions (conversational speech formulas, pause fillers, idioms, and other fixed expressions) is excessive in the left hemisphere and deficient in the right hemisphere and in subcortical stroke. Speakers with Alzheimer's disease (AD), having functional basal ganglia, reveal abnormally high proportions of formulaic language. Persons with Parkinson's disease (PD), having dysfunctional basal ganglia, were predicted to show impoverished formulaic expressions in contrast to speakers with AD. This study compared participants with PD, participants with AD, and healthy control (HC) participants on protocols probing production and comprehension of formulaic expressions. Method: Spontaneous speech samples were recorded from 16 individuals with PD, 12 individuals with AD, and 18 HC speakers. Structured tests were then administered as probes of comprehension. Results: The PD group had lower proportions of formulaic expressions compared with the AD and HC groups. Comprehension testing yielded opposite contrasts: participants with PD showed significantly higher performance compared with participants with AD and did not differ from HC participants. Conclusions: The finding that PD produced lower proportions of formulaic expressions compared with AD and HC supports the view that subcortical nuclei modulate the production of formulaic expressions. Contrasting results on formal testing of comprehension, whereby participants with AD performed significantly worse than participants with PD and HC participants, indicate differential effects on procedural and declarative knowledge associated with these neurological conditions. C linical descriptions of formulaic language in aphasic speech have flourished for more than 150 years under a wide variety of terms. Formulaic language, in its modern conception, consists of fixed, unitary expressions known to a language community with their characteristic form, meaning, and usage conditions. Typical examples are conversational speech formulas ("You betcha," "You've got to be kidding," and "Say what?"), expletives ("heck"), idioms ("as the crow flies," "That's the way the cookie crumbles"), proverbs ("When it rains, it pours"), and other conventionalized expressions ("all things being equal," "in the meantime," and "the long and the short of it is"; Altenberg, 1998;Biber, 2009;Kuiper, 2004;Wray, 2002). These expressions share the features of fixed or canonical form; conventionalized, often nonliteral meaning; and specific relations to discourse context.As reviewed in Van Lancker (1973, 1975, 1994, formulaic language has its venerable beginnings in observations by J. Hughlings Jackson (1874aJackson ( /1932Jackson ( , 1874bJackson ( /1932, who labeled the preserved expressions seen in adults with language disability following left-brain damage automatic or nonpropositional speech. Examples cited by Hughlings Jackson include phrases belonging classically to the conception of formulaic expressions: "Take care," "That's a lie," "Good bye," "Oh dear," and "Bles...
Background:This study evaluated the effect of vege-powder (VP), mainly consisted of chicory, broccoli, and whole grains, on bowel habit improvement and constipation alleviation.Methods:Using the Roman standard II, 96 male and female subjects in their twenties with constipation symptoms were divided into a control group or VP group. Subjects in a control group were supplied with rice flakes-powder (RFP) and subjects in the VP group were provided with 30 g of VP twice daily for 4 weeks. Constipation relief effectiveness was surveyed on 5-point Likert scales depending on stool hardness, amount of stool, sensation of incomplete evacuation, and straining to defecate at day 0, 14, and 28 of RFP or VP intake.Results:Repeated measures analysis of variance analysis revealed that VP intake caused significant temporal changes in stool hardness, amount, sensation of incomplete evacuation, and straining to defecate. In addition, significant differences between control and VP groups were found in stool hardness, amount, sensation of incomplete evacuation, and straining to defecate at day 14 and 28 of experimental diet consumption. VP supplement for 2 weeks significantly increased the evacuation frequency (1.04 ± 0.71), compared to control group (0.41 ± 0.64) and this increase was maintained at 4 week of diet supplements.Conclusions:This result showed that constipated subjects who consumed VP, mainly consisting of chicory, broccoli, and whole grains, improved constipation symptoms at 2 and 4 weeks of consumption compared to those of control group who were provided with RFP.
For many years, brain ischemia has been known to be a leading cause of adult neurological disorder. In particular, many reports have shown that hyperexcitability of neurons and inflammatory response of the glia induced by ischemic reperfusion (I/R) determine the fate of cells in the ischemic core and the penumbra region. Although there are many reports on the activation and roles of signal transducer and activator of transcription (STAT) proteins (STAT1, STAT3, and STAT5) during hyperexcitation in the neuron and inflammation occurring following I/R, the temporal and spatial activation of STAT6 protein in the ischemic cortex still remain elusive. In this study, using a transient rat middle cerebral artery occlusion model, we primarily investigated the time-course expression of the phosphorylated STAT6 (pSTAT6) in the ischemic core region following I/R, which was compared with that of pSTAT3. We found that pSTAT6 significantly decreases at 1 and 12 h following I/R, whereas pSTAT3 markedly increases at each follow-up time point. In addition, the level of pSTAT6 is reduced in the ischemic core in comparison with the penumbra region at 12 h following I/R. However, there is no significant difference in pSTAT3 expression between the ischemic core and the penumbra. Taken together, our data suggest that pSTAT6 and pSTAT3 are modulated differently following I/R during ischemic stroke.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
