Pefloxacine mesilate- and ofloxacin-loaded polyethylcyanoacrylate nanoparticles: characterization of the colloidal drug carrier formulation.
1995
The entrapment of fluoroquinolones, perfloxacine mesilate (PFX) and ofloxacin (OFX), in polyalkylcyanoacrylate (PECA) nanoparticles could offer some advantages for their biological application; for examples, increasing their bioavailability, controlling the drug time-release in blood, and reducing the formation of bacterial resistance. To load these two drugs in PECA polymeric bulk, the incorporation or adsorption method was performed. These two methods were capable of influencing nanoparticle size, molecular weight, release profile, and drug–polymer association. The incorporation method, particularly for the OFX system, achieved PECA nanoparticle suspensions with a mean size value three ti…
IMPAIRED ALLOCENTRIC SPATIAL MEMORY UNDERLYNG TOPOGRAPHICAL DISORIENTATION
2006
The cognitive processes supporting spatial navigation are considered in the context of a patient (CF) with possible very early Alzheimer's disease who presents with topographical disorientation. Her verbal memory and her recognition memory for unknown buildings, landmarks and outdoor scenes was intact, although she showed an impairment in face processing. By contrast, her navigational ability, quantitatively assessed within a small virtual reality (VR) town, was significantly impaired. Interestingly, she showed a selective impairment in a VR object-location memory test whenever her viewpoint was shifted between presentation and test, but not when tested from the same viewpoint. We suggest t…
Fathers’ marital satisfaction and their involvement with their child with disabilities
2011
The study examines whether fathers’ marital satisfaction – that is, relationships within the parents’ marriage – is correlated with their involvement with their child with disabilities. Data were collected from 243 Polish fathers who were married and who had at least one child with disabilities. The issue was assessed by two measures, the Marital Satisfaction Scale and the Father Involvement Scale. The results show that fathers’ marital satisfaction is significantly (p 0.05) correlated with the fifth component of fathers’ involvement with their child with disabilities, active help in achieving independence by their children.
A context-aware approach for long-term behavioural change detection and abnormality prediction in ambient assisted living
2015
This research aims to describe pattern recognition models for detecting behavioural and health-related changes in a patient who is monitored continuously in an assisted living environment. The early anticipation of anomalies can improve the rate of disease prevention. Here we present different learning techniques for predicting abnormalities and behavioural trends in various user contexts. In this paper we described a Hidden Markov Model based approach for detecting abnormalities in daily activities, a process of identifying irregularity in routine behaviours from statistical histories and an exponential smoothing technique to predict future changes in various vital signs. The outcomes of t…
Recognition of Falls and Daily Living Activities Using Machine Learning
2018
A robust fall detection system is essential to support the independent living of elderlies. In this context, we develop a machine learning framework for fall detection and daily living activity recognition. Using acceleration data from public databases, we test the performance of two algorithms to classify seven different activities including falls and activities of daily living. We extract new features from the acceleration signal and demonstrate their effect on improving the accuracy and the precision of the classifier. Our analysis reveals that the quadratic support vector machine classifier achieves an overall accuracy of 93.2% and outperforms the artificial neural network algorithm. Re…
Gender differences in child and adolescent daily activities : a cross-national time use study
2021
This study used 2009–2015 time-diary data to examine gender differences in daily activities among children and adolescents aged 10–17 in Finland, Spain and the UK ( N = 3517). In all three countries, boys were significantly more involved in screen-based activities and exercising and girls in domestic work, non-screen educational activities and personal care. Gender differences in socializing time were only significant in the UK, with girls socializing more than boys. Gender gaps within countries were largest in domestic work (UK: 60%; Finland: 58%; Spain: 48%) and exercising (UK: 57%; Finland: 36%; Spain: 27%), followed by educational time (UK: 35%; Finland: 34%; Spain: 18%) and screen-bas…
The importance of moral sensitivity when including persons with dementia in qualitative research
2012
Author's version of an article in the journal: Nursing Ethics. Also avaliable from the publisher at: httjp://dx.doi.org/10.1177/0969733012455564 The aim of the article is to show the importance of moral sensitivity when including persons with dementia in research. The article presents and discusses ethical challenges encountered when a total of fifteen persons with dementia from two nursing homes and seven proxies were included in a qualitative study. The examples show that ethical challenges may be unpredictable. As researcher you participate with the informants in their daily life and in the interview situation, and it is not possible to plan all that may happen. A procedural proposal to …
Togetherness — A Manifestation of Day Care Life
1999
This article discusses togetherness in the day care centre. In what way and in which situations is togetherness expressed among children? “What is the impact of adults on the rise and development of togetherness?” Answers to these questions were sought by making use of observations carried out in a cooperative Nordic study of the quality of children's lives in Danish, Finnish and Swedish day care centres. The data were collected by observing five‐year‐old children during their daily activities in seven day care centres. Attention was paid to relations between the children and adults as well as to the objects — in the sense of contents and objectives of ongoing activities. What do individual…
Community dimensions and emotions in the era of COVID-19
2021
Abstract Following an ecological perspective, reactions to a disaster—such as the COVID‐19 pandemic—should be analysed in the interdependence between individual and community dimensions. The present study aims to analyse individual emotional dimensions (anxiety, joy, fear or depressive feelings) and their community dimensions (connectedness, emotional sharing and solidarity) with a longitudinal approach among university students from Italian universities. Participants were 746 university students at t1 (during the lockdown) and 361 at t2 (after the lockdown) recruited in six Italian universities from different areas of Italy. Comparing emotional dimensions in the two times, t2 is characteri…
Anxiety and pain perception in patients undergoing mandibular autogenous block bone surgery
2020
Background The aim of the present study was to investigate pain perception and anxiety within the context of surgery for the placement of mandibular block bone and to evaluate the causality effect between theses variables. Material and methods A total of 13 patients were recruited for the study and were submitted to mandibular autogenous block bone surgery. Demographic data were collected and the anxiety level was determined using the State-Trait Anxiety Inventory (STAI). The STAI was administered on the day of surgery and on the 14th postoperative day. Pain was determined using the visual analogue scale (VAS) and limitation of daily activities and postoperative symptoms were also reported.…
