Neuropsychological status of alcohol-dependent patients: increased performance through goal-setting instructions.
2004
Aims: The effects of goal-setting instructions on neuropsychological performance of alcohol-dependent patients and control subjects were assessed. Methods: 57 alcohol-dependent patients and 59 carefully age- and education-matched healthy control subjects underwent standard neuropsychological investigation. In addition, the goal-setting paradigm was used to systematically manipulate motivation. Participants were requested to calculate simple mathematical problems repeatedly within phases of a 2-min duration receiving normal or goal setting-instructions (to increase performance in the next phase by 20%). Results: The patients demonstrated deficits in standard neuropsychological tests. Patient…
Computer Games and Fine Motor Skills
2012
The study seeks to determine the influence of computer games on fine motor skills in young adults, an area of incomplete understanding and verification. We hypothesized that computer gaming could have a positive influence on basic motor skills, such as precision, aiming, speed, dexterity, or tremor. We examined 30 habitual game users (F/M – 3/27; age range 20–25 years) of the highly interactive game Counter Strike, in which players impersonate soldiers on a battlefield, and 30 age- and gender-matched subjects who declared never to play games. Selected tests from the Vienna Test System were used to assess fine motor skills and tremor. The results demonstrate that the game users scored apprec…
Supporting public decision process in buildings energy retrofitting operations: the application of a Multiple Criteria Decision Aiding model to a cas…
2020
Abstract The challenge of promoting sustainable cities and reaching the objectives developed by the European Green Deal includes the renovation of the building sector, as it is responsible for 40% of energy consumption in Europe. Regional or local public administrations have to allocate their financial resources for improving the energy performances of their building stock and to face a multidimensional problem, where different aspects – such as energy efficiency, financial-economic feasibility and environmental protection – have to be harmonized. The present study proposes a Multiple Criteria Decision Aiding model, which includes the ELECTRE TRI-nC method, for supporting the public decisio…
The bronchodilatory effect of deep inspiration diminishes with aging
2004
AbstractDeep inspirations have the ability to dilate constricted airways. The impairment of this function has been associated with the occurrence of asthmatic symptoms. We evaluated whether the bronchodilatory effect of deep inspiration (DI) is affected by aging. We tested 25 healthy subjects (median age: 54 yrs, range: 25–83 yrs). Single dose methacholine (Mch) provocations were performed in the absence of DI, which induced at least 15% reduction in inspiratory vital capacity (IVC) from baseline. The post-Mch IVC measurement was followed by 4 DIs and by another IVC (post-DI IVC). The fractional difference between post-DI IVC and post-Mch IVC represented the % bronchodilation by DI. The % b…
Real time analysis of volatile organic compounds (VOCs) in centenarians.
2014
Centenarians are a model to study human longevity and the physiological process of aging. A plethora of studies on this model show the complexity of the system. Laboratory studies fail to find a biomarker of senescence. The real time exhaled breath volatile organic compounds (VOCs) has been suggested as a new biomarker to detect and monitor physiological processes in the respiratory system. VOCs exhaled by centenarians have not been studied in the general population and across-age-groups. In the present study we investigated, in real time, the breath properties and VOC exhaled content in healthy centenarians as compared with non-centenarian seniors and young healthy subjects. We found disti…
Bronchial responsiveness and airway inflammation in trained subjects
2008
We read with interest the paper by Shaaban and coworkers1 on the protective effect of physical activity against bronchial hyperreactivity (BHR) in the general population. The authors suggest that a beneficial effect of deep inspirations during exercise could account for the lower prevalence of BHR in physically active subjects compared with sedentary subjects, while the accompanying editorial2 favours an “anti-inflammatory” effect of exercise as the most plausible explanation. We have studied lung function and airway cell biology …
