Differential Effects of Verapamil on Various Gastric Lesions in Rats
1988
Verapamil (3, 10, 20 mg/kg-1) increases the necrotizing effects of oral 25% NaCl or 100% ethanol. Damage by 0.6 N HCl was not equally affected since 1 mg/kg-1 of verapamil decreased the ulcer index whereas the higher doses augmented it. Pharmacologically induced gastric lesions were also differently affected by verapamil, ulcers produced by histamine being greatly enhanced and those of reserpine inhibited. Neither indomethacin nor compound 48/80 ulcers were modified. These results suggest that verapamil modifies the susceptibility of the gastric mucosa to damage.
The heterogeneity of services and the differential effects on business and territorial innovation
2011
The innovative results of firms depend upon their specific characteristics and their ability to weave together their competences with the innovative resources in their environment. Different approaches have underlined the importance of location and the context of business innovation. In particular, the existence of knowledge intensive services (KIS) enables firms to create and commercialise new processes, products and services. However, KIS can present substantial differences in their capacity to contribute to innovation. This article examines the relationship between KIS and business innovation and establishes a KIS typology in order to pinpoint its effects on business innovation. The resu…
Differential effects of perceptions of equal, favourable and unfavourable autonomy support on educational and well-being outcomes
2019
Abstract In this study, we examined whether high-school students experienced optimal educational and well-being outcomes when they perceived that they and their classmates received an equal, rather than unequal, and high amount of autonomy support from teachers. In a prospective study that aimed to predict academic grades and well-being outcomes, surface analyses of polynomial regression equations pointed that perceptions of equal autonomy support were the most optimal in terms of yielding highest levels of need satisfaction, autonomous forms of motivation and happiness with math courses. Additionally, in accordance with tenets of self-determination theory, we demonstrated that effects asso…
Previous Training in the Water Maze
1999
It has been shown that acquisition rates in the water maze vary across strains of mice, although the differential effects of previous experience in this spatial task have been scarcely evaluated. The aim of the present study was to evaluate the effects of training in the water maze at an early age (2 months) in two strains of mice (NMRI and C57BL) using a longitudinal study. Mice with or without previous training were tested when they were 6 months, and retested when 10 months old. The results showed that trained NMRI mice performed better than all the other groups, both at test and retest, indicating that previous training had more beneficial effects in NMRI than in C57BL mice. These resul…

Interruptions (interfering stimuli to respond to) and distractions (interfering stimuli to be ignored) have been shown to negatively impact performance, particularly in tasks requiring working memory (WM). This study investigated how these two types of external interference affect task performance and attentional and WM processes as indexed by specific event-related potentials (ERPs) of the EEG. A Continuous Number Task (CNT) was applied, in which participants had to either decide whether the current number (condition without WM load) or the sum of the current and the preceding number (condition with WM load) was odd or even while responding to interlaced single letters (interruptions) or i…
Differential effects of age on subcomponents of response inhibition.
2013
Inhibitory deficits contribute to cognitive decline in the aging brain. Separating subcomponents of response inhibition may help to resolve contradictions in the existing literature. A total of 49 healthy participants underwent functional magnetic resonance imaging (fMRI) while performing a Go/no-go-, a Simon-, and a Stop-signal task. Regression analyses were conducted to identify correlations of age and activation patterns. Imaging results revealed a differential effect of age on subcomponents of response inhibition. In a simple Go/no-go task (no spatial discrimination), aging was associated with increased activation of the core inhibitory network and parietal areas. In the Simon task, whi…
R&D subsidies & external collaborative breadth: Differential gains and the role of collaboration experience
2018
The file attached to this record is the author's final peer reviewed version. External collaboration breadth is important for firms to acquire the knowledge needed to innovate. In this paper, we combine cross-sectional and longitudinal data from the Spanish Panel of Technological Innovation Survey (PITEC) to examine the indirect impact of R&D subsidies on firm external collaboration breadth. We contribute to understanding of the indirect impacts of R&D subsidies by first providing strong evidence of an economically significant average positive impact of R&D subsidies on firm external collaboration breadth. Second, our results advance understanding of the differential impacts of R&D subsidie…
A typological approach of perceived resource fluctuations after job transitions in a representative panel study
2020
Job and career transitions are unique experiences that vary within and between persons. One possible reason for the differential effects of transitions is that they can involve resource gains, loss...

Objectives: The present naturalistic study aims to investigate the differential effects of the patient’s and the therapist’s attachment representations on the attachment to the therapist as perceived by the patient, and their impact on self-esteem-change through psychotherapy.Methods: Attachment variables of N = 573 patients as well as N = 16 therapists were assessed. Attachment representations were measured for therapists and patients via the Bielefelder Questionnaire for Client Attachment Exploration, the Relationship Specific Attachment to Therapist Scales and the Adult Attachment Interview. The patient’s attachment to therapists was evaluated and patients’ self-esteem was measured via t…
