The relationship between the level of physical activity, independence in daily activities, and life quality and satisfaction in women over 80 living …

Wprowadzenie. Rosnący poziom opieki zdrowotnej stale zwiększa długość życia ludzi. Rosnąca liczba osób starszych i zaburzenie równowagi w strukturze populacji wpłynie na wiele dziedzin życia, w tym na system ubezpieczeń społecznych, orientację zawodową osób pracujących czy kulturę. Dlatego bardzo ważne jest, aby osoby starsze zachowały nie tylko dobre zdrowie fizyczne, ale także utrzymywały zdolność do samoopieki tak długo, jak to możliwe, pozostały sprawne funkcjonalnie i wyrażały zadowolenie z życia we wszystkich dziedzinach. Cel. Niniejsze badanie ma na celu analizę czynników wpływających na jakość życia w różnych dziedzinach (fizyczna, psychologiczna, społeczna i środowiskowa), takich j…

Progression of functional limitations in relation to physical activity: a life course approach

2010

Abstract In this minireview, we summarize the research results to date on the progression of functional limitations and the role of physical activity during the life course in preventing risk factor accumulation. In addition, socioeconomic and health disparities play a role in the development process of functional limitation throughout life. We discuss the potential role of physical activity in alleviating this process. Functional limitations usually develop gradually over an extended period of time while the level of physical functioning varies greatly already from midlife onwards. Current research strongly suggests that physical activity has a beneficial effect on functional limitations a…

Is Physical Exercise Harmful to Liver Transplantation Recipients? Review of Literature

2015

Liver transplantation is a treatment that significantly improves the patients' quality of life. However, we should be more ambitious and seek an improvement in their fitness through training protocols allowing them to fully return to daily activities. English and Spanish-language articles on PubMed and the Cochrane Library were searched untill 2014. Articles were reviewed by 2 of the authors to determine if they were suitable for inclusion. It is shown a compilation of studies that included patients who have participated in aerobic, strength, or both combined training programs, without implying a risk for the graft function. There is a lack of studies with high scientific evidence that stab…

Physical performance in relation to menopause status and physical activity

2018

Objective: The aim of this study was to examine differences in physical performance (muscle power, muscle strength, aerobic capacity, and walking speed) across menopausal stages and potential of leisure physical activity (PA) to modify the impact of menopause on physical performance. Methods: In this cross-sectional study, women aged 47 to 55 were randomly selected from the Finnish National Registry and categorized as premenopausal (n ¼ 233), perimenopausal (n ¼ 381), or postmenopausal (n ¼ 299) based on serum concentrations of follicle-stimulating hormone and bleeding diary. Physical performance was measured by knee extension force, handgrip force, vertical jumping height, maximal walking …

Functional data analysis for optimizing strategies of cash flow management

2015

The cash management deals with problem of automating and managing cash flow processes. Optimization of the management processes greatly reduces overall cash handling costs. The present analysis is an empirical study of cash flows, from and to bank branches, deriving an underlying theoretical framework, which can in a reasonable way be connected with the optimal strategy. Functional data analysis is considered an appropriate framework to analyse the dynamics of the time series behavior of cash flows: since the observations are not equally spaced in time and their number is different for each series, they are converted in a collection of random curves in a space spanned by finite dimensional …

Strong Bonding of Single C60 Molecules to (1 × 2)-Pt(110): an STM/DFT Investigation.

2007

International audience; The interaction of single C60 molecules with the (1 × 2)-Pt(110) surface has been studied by scanning tunneling microscopy and density functional theory (DFT) calculations on slab models. Molecules are observed to be frozen at room temperature and are found to be almost exclusively in the same configuration. Extensive DFT calculations show that this configuration is the global energy minimum, suggesting that adsorbed molecules have enough rototranslational freedom to escape from the numerous local minima. The adsorption energy (3.81 eV) is the strongest ever found for C60, and it is roughly proportional to the number of the Pt and C atoms at contact distance. Analysi…

Squaric Acid Mediated Synthesis and Biological Activity of a Library of Linear and Hyperbranched Poly(Glycerol)-Protein Conjugates

2012

Polymer-protein conjugates generated from side chain functional synthetic polymers are attractive because they can be easily further modified with, for example, labeling groups or targeting ligands. The residue specific modification of proteins with side chain functional synthetic polymers using the traditional coupling strategies may be compromised due to the nonorthogonality of the side-chain and chain-end functional groups of the synthetic polymer, which may lead to side reactions. This study explores the feasibility of the squaric acid diethyl ester mediated coupling as an amine selective, hydroxyl tolerant, and hydrolysis insensitive route for the preparation of side-chain functional, …

Adsorption of the herbicide 4-chloro-2-methylphenoxyacetic acid (MCPA) by goethite.

2014

Interaction between the goethite surface and 4-chloro-2-methylphenoxyacetic acid (MCPA) herbicide was studied using density functional theory (DFT) calculations combined with molecular dynamics (MD). The important step made here lies in the use of a periodic DFT method enabling the study of a mineral surface of different protonation states, in strong contrast with previous molecular modeling studies limited to single protonation state corresponding to the point of zero charge. Different surface OH groups and MCPA proton states were used to mimic the strong effects of pH on the outer- and inner-sphere surface complexes that are theoretically possible, together with their binding energies, an…

A topological isomer of the Au25(SR)18−nanocluster

2020

Energetically low-lying structural isomers of the much-studied thiolate-protected gold cluster Au25(SR)18− are discovered from extensive (80 ns) molecular dynamics (MD) simulations using the reactive molecular force field ReaxFF and confirmed by density functional theory (DFT). A particularly interesting isomer is found, which is topologically connected to the known crystal structure by a low-barrier collective rotation of the icosahedral Au13 core. The isomerization takes place without breaking of any Au–S bonds. The predicted isomer is essentially iso-energetic with the known Au25(SR)18− structure, but has a distinctly different optical spectrum. It has a significantly larger collision cr…
