Burnout among occupactional therapists in Portugal

Sistema integrado de monitorização agrícola de longo alcance

Recentes avanços tecnológicos têm permitido o nascimento de novas redes sem os de baixo consumo e de baixo custo. O aparecimento destas redes permite também o aparecimento de novos sistemas de monitorização que antigamente se classi cavam como inviáveis devido ao grande investimento necessário. Exemplo disto são os sistemas de monitorização agrícola facilitando os processos e tornado-os mais e cientes. Neste do...

Optimization of a perfusion bioreactor for tissue engineering

Tissue engineering aims to produce artificial tissue in order to create or repair the damage tissue. It is evident that scaffolds are of extreme importance, because they will be the support of the new tissue. This new tissue is cultivated in vitro in a bioreactor in which is placed the scaffold. In order to control the cell culture process inside of a bioreactor it is essential to know the fluid flow inside and...

Inhalation of peptide-loaded nanoparticles improves heart failure

Peptides are highly selective and efficacious for the treatment of cardiovascular and other diseases. However, it is currently not possible to administer peptides for cardiac-targeting therapy via a noninvasive procedure, thus representing scientific and technological challenges. We demonstrate that inhalation of small (<50 nm in diameter) biocompatible and biodegradable calcium phosphate nanoparticles (CaPs) a...

Effect of Chromatographic Conditions on Supercoiled Plasmid DNA Stability and B...

The dysfunction of the tumor suppressor gene TP53 has been associated with the pathogenesis of the majority of the cases of cancer reported to date, leading the cell to acquire different features known as the cancer hallmarks. In normal situations, the protein p53 protects the cells against tumorigenesis. By detecting metabolic stress or DNA damage in response to stress, p53 can lead the cell to senescence, aut...

Glyphosate-based herbicide toxicophenomics in marine diatoms: impacts on primar...

Glyphosate is the main active component of the commercial formulation Roundup®, the most widely used chemical herbicide worldwide. However, its potential high toxicity to the environment and throughout trophic webs has come under increasing scrutiny. The present study aims to investigate the application of bio-optical techniques and their correlation to physiological and biochemical processes, including primary...

Hábitos e Rotinas na Perturbação da Hiperatividade/ Défice de Atenção

O presente trabalho surge no âmbito do Mestrado em Educação Especial – domínio cognitivo- motor (IPL/ESECS) e visa estudar a importância dos hábitos e das rotinas para as crianças com Perturbação da Hiperatividade/Défice de Atenção (PHDA). Seguindo a lógica de uma revisão sistemática de literatura, recorreu-se à pesquisa e análise de estudos realizados com crianças com PHDA, com idades entre os 6 e os 16 anos, ...
