KEEP EXPLORING
The behavioural phenotype of transgenic mice (3- to 5-months old) overexpressing galanin (GalOE) under the platelet-derived growth factor B (PDGF-B) promoter was evaluated in a battery of tests, including open field, locomotor cages, light-dark exploration test, elevated plus-maze and the Porsolt forced swim test. Learning and memory were assessed in the passive avoidance and the Morris water maze tasks. No difference between genotypes was found in exploratory activity in the open field. GalOE mice showed a slight increase in spontaneous locomotor activity assessed in the locomotor cages, but the amphetamine-induced increase in locomotor activity was somewhat lower in GalOE mice. Anxiety-like behaviour in the three different tests including open field, light-dark exploration and elevated plus-maze did not differ between genotypes. In the Porsolt forced swim test, GalOE mice displayed an increased time of immobility, indicative of increased learned helplessness possibly reflecting increased stress-susceptibility and/or depression-like behaviour. GalOE mice showed normal learning and memory retention in the passive avoidance and the Morris water maze tasks. These data support the hypothesis that galanin may have a role in functions related to mood states including affective disorders.
OBJECTIVE: This study examined the effects of reminiscence on depressive symptoms and mood status of elderly people residing in long-term care facilities. METHODS: A longitudinal quasi-experimental design was conducted, using two equivalent groups for pre-post test and purposive sampling. Each subject was administered pre- and post- tests at a 4 month interval, but subjects in the experimental group underwent weekly individual reminiscence therapy. Geriatric Depression Scale short form (GDS-SF) and Apparent Emotion Rating Scale (AER) were used as study instruments. RESULTS: Forty-eight subjects completed the study, with 25 in the experimental group and 23 in the control group. The experimental findings indicated that the experimental group demonstrated fewer depressive symptoms (p < 0.05) and better mood status (p = 0.05) on the post-test comparing to the control group. CONCLUSION: These warranted that reminiscence therapy is a recommended therapy for older people who reside in care facilities. It can provide a basis for planning geriatric care in community to promote the well being and quality of life of older people.
This study presents results from sentence-completion and grammaticality-judgement tasks with seven German-speaking agrammatic aphasics and seven age-matched control subjects examining verb finiteness marking and verb-second (V2) placement. The patients were found to be selectively impaired in tense marking in the face of preserved mood and agreement marking. Moreover, our results revealed that V2 scores varied across our patients, with some showing impaired and others preserved V2 performance. These findings will be discussed in the light of different syntactic accounts of agrammatism.
