Surface-modified 3D starch-based scaffold for improved endothelialization for bone tissue engineering
2009
Providing adequate vascularization is one of the main hurdles to the widespread clinical application of bone tissue engineering approaches. Due to their unique role in blood vessel formation, endothelial cells (EC) play a key role in the establishment of successful vascularization strategies. However, currently available polymeric materials do not generally support EC growth without coating with adhesive proteins. In this work we present argon plasma treatment as a suitable method to render the surface of a 3D starch-based scaffold compatible for ECs, this way obviating the need for protein pre-coating. To this end we studied the effect of plasma modification on surface properties, protein …
Alginate/silica composite hydrogel as a potential morphogenetically active scaffold for three-dimensional tissue engineering
2013
Pursuing our aim to develop a biomimetic synthetic scaffold suitable for tissue engineering, we embedded bone cells, osteoblast-related SaOS-2 cells and osteoclast-like RAW 264.7 cells, into beads, formed of a Na-alginate-based or a silica-containing Na-alginate-based hydrogel matrix. The beads were incubated either separately (only one cell line in a culture dish) or co-incubated (SaOS-2-containing beads and RAW 264.7 beads). The alginate and alginate/silica hydrogel matrices were found not to impair the viability of the encapsulated cells. In these matrices the SaOS-2 cells retain their capacity to synthesize hydroxyapatite crystallites. The mechanical properties, including surface roughn…

Physicochemical properties, sugar profile, and non-starch polysaccharides characterization of old wheat malt landraces
2021
Abstract Craft beers produced by small breweries are becoming increasingly popular worldwide due to their unique composition, taste, and flavour. Wheat malt is a traditional brewing raw material with great potential to improve beer properties such as mouthfeel, foam, haze, and flavour. In this study, the malting quality of eight wheat varieties (four common and four durum) was evaluated to explore the feasibility of producing 100 % wheat malt beer from old landraces. The physicochemical characteristics such as friability, Kolbach index, viscosity, and colour, of the wheat malts indicated a better degree of modification in the common wheat varieties when compared to that of the durum wheat v…
Cold-water immersion combined with active recovery is equally as effective as active recovery during 10 weeks of high-intensity combined strength and…
2019
Summary Study aim: The purpose of this study was to compare the effects of cold-water immersion (CWI) vs. active recovery performed after each individual strength and endurance training session over a 10-week period of high-intensity combined strength and endurance training. Materials and methods: Seventeen healthy men completed 10 weeks of high-intensity combined strength and endurance training. One group (AR, n = 10) completed active recovery that included 15 minutes of running at 30–40% VO2max after every strength training session while the other group (CWI, n = 7) completed 5 minutes of active recovery (at the same intensity as the AR group) followed by 10 minutes of cold-water (12 ± 1°…
Effects of a home-based rehabilitation program in community-dwelling older people after discharge from hospital: A subgroup analysis of a randomized …
2021
Objective: To examine whether pre-admission community mobility explains the effects of a rehabilitation program on physical performance and activity in older adults recently discharged from hospital. Design: A secondary analysis of a randomized controlled trial. Setting: Home and community. Participants: Community-dwelling adults aged ⩾60 years recovering from a lower limb or back injury, surgery or other disorder who were randomized to a rehabilitation ( n = 59) or standard care control ( n = 58) group. They were further classified into subgroups that were not planned a priori: (1) mild, (2) moderate, or (3) severe pre-admission restrictions in community mobility. Interventions: The 6-mont…
Cross-border mobility and long-distance communication as modes of care circulation: insights from the Peruvian ‘zero generation’
2016
ABSTRACTThe contribution of older family members in the sending countries to the well-being of transnational families has only recently come more into the focus of research. Cross-border mobility and long-distance communication are two central modes through which the members of this ‘zero generation’ engage in transnational family life. By applying the framework of care circulation, this paper seeks to discuss the influence of cross-border mobility and long-distance communication on older Peruvian non-migrants’ engagement in transnational family care arrangements. The paper shows, first, that political and economic factors, as well as communication infrastructures, shape the patterns of the…
Gated Housing Estates in the Arab World: Case Studies in Lebanon and Riyadh, Saudi Arabia
2002
The authors analyze the cultural, economic, and political background of new gated housing estates in the Arab world with the aid of case studies in Lebanon and Riyadh. Their question is to what extent these developments represent a reappearance of the fragmented settlement patterns in many of the old towns. On the one hand, new compounds of several villas and common facilities housing extended families in Riyadh may be interpreted as a revival of certain sociospatial settings in the old town, in which extended families often shared a common courtyard. The compounds for Western foreigners in Saudi Arabia follow the principle of spatial seclusion of social groups with different cultural and r…
