Preliminary evaluation of zeolite-based platforms as potential dual drug delive...

Several zeolite-based delivery systems (ZDS) built with faujasite structure were prepared containing silver (Ag+) and 5-Fluorouracil (5-FU) as antimicrobial and antineoplastic agents, respectively. The idea behind this drug combination is an answer to the increasing evidence of colonization of tumor microenvironments by pathogenic microorganisms and their active role in tumor growth. Two ZDS with a fixed load o...

The promotion of psychological development in the aging process

The purpose of this paper is to present the main theoretical and empirical foundations for the promotion of psychological development with older people. The orientation of developmental psychology to older people has arisen because of interest among psychologists in using developmental approaches of human behavior and development for understanding the plasticity of the aging mind and development, and the import...

Performance of self-cleaning cotton textiles coated with TiO2, TiO2-SiO2 and Ti...

In the present study composites based on TiO(2 )nanoparticles, SiO2 and HY zeolite were synthesized by using a standard sol-gel methodology and analyzed by Fourier-transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy-energy-dispersive X-ray spectroscopy techniques. The photocatalysts were impregnated on cotton textiles and their photocatalytic abilities were examined by degradatio...

Aging in place in Portugal

Aging in place means the ability to continue living at home and in the community over time, safely and independently. The promotion and enhancement of aging modalities at home and in the community is a model of social intervention currently favored by the World Health Organization as people get older (WHO, 2015). In this article we present the main data resulting from the collection and systematization of about...

Building a model to analyse and compare social policies on ageing

Demographic ageing results in issues both for individuals and for organizations, with regards to social, economic and health issues. The challenge for public policies is to create the adequate resources and to adapt devices, in order to facilitate and allow an ageing process with well-being. The WHO’s proposal of Active Ageing has a great potential in guiding ageing policies, in particular local interventions. ...

Ageing in place e intervenção psicológica no domicílio

Pretende-se com esta comunicação caracterizar e valorizar o que é habitualmente designado por ageing in place (“envelhecer em casa e na comunidade”, em tradução livre), designadamente, no que respeita à promoção da inclusão social dos cidadãos mais velhos nas respetivas comunidades.

Identifying priorities for aging policies in two Portuguese communities

The aging population has an impact on health, social and economic issues in regards to individuals, communities and organizations. The challenge for local policies in response to aging is to create sufficient resources to meet the population’s needs, wishes and rights as people age. Active aging constitutes one of the guiding perspectives on policies. Taking into account the local governance perspective, the in...

Modification of microfluidic paper-based devices with dye nanomaterials obtaine...

Zeolite nanostructures were used as hosts for dyes normally used in some bioassays (pH and protein), and applied on microfluidic paper-based analytical devices (PADs). The obtained dye nanomaterials were characterized by several techniques (structural (FTIR and XRD), surface (SEM/EDX), textural (N2 adsorption) analyses and dye loading determination by TGA analysis), to confirm the stability of both host and gue...

Appropriation and use of new technologies by Portuguese elderly in a Senior Uni...

This paper reports a research carried out with Portuguese elderly, intended to investigate the influences and computer learning resonances in their sociability. Interviews were conducted with six elderly participants of a Internet course of the Universidade Sénior Contemporânea, in the city of Porto, Portugal.
