Identification of Antibiotics in Surface-Groundwater. A Tool towards the Ecopha...

Environmental monitoring, particularly of water, is crucial to screen and preselect potential hazardous substances for policy guidance and risk minimisation strategies. In Portugal, extensive data are missing. This work aimed to perform a qualitative survey of antibiotics in surface- groundwater, reflecting demographic, spatial, consumption and drug profiles during an observational period of three years. A pass...

Spiro-β-lactam BSS-730A Displays Potent Activity against HIV and Plasmodium

The high burden of malaria and HIV/AIDS prevents economic and social progress in developing countries. A continuing need exists for development of novel drugs and treatment regimens for both diseases in order to address the tolerability and long-term safety concerns associated with current treatment options and the emergence of drug resistance. We describe new spiro-β-lactam derivatives with potent (nM) activit...

A proposed lectin‐mediated mechanism to explain the in Vivo antihyperglycemic a...

Experiments conducted in vitro and in vivo, as well as clinical trials for hypoglycemic therapeutics, support the hypoglycemic properties of the lectin γ-conglutin, a Lupinus seed storage protein, by a mechanism not yet been clarified. Structural studies established that binding of γ-conglutin, in native and denatured form, to insulin occurs by a strong binding that resists rupture when 0.4 M NaCl and 0.4 M gal...

Patient access to gene therapy medicinal products : a comprehensive review

Background Gene therapies have the potential to be a curative approach to a large number of genetic diseases. However, granting of a positive marketing authorisation does not equal patient access to therapy. Objectives The purpose of this paper is to identify a full set of hurdles potentially preventing patient access to gene therapies based on the available literature. Methods A review of the literature using ...

Lupinus albus protein componentes inhibit MMP-2 and MMP-9 gelatinolytic activit...

Matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9) are regarded as important clinical targets due to their nodal-point role in inflammatory and oncological diseases. Here, we aimed at isolating and characterizing am MMP-2 and-9 inhibitor (MMPI) from Lupinus albus and at assessing its efficacy in vitro and in vivo. The protein was isolated using chromatographic and 2-D electrophoretic procedures and sequenced b...

The Challenges of the European Medicines Evaluation by 2025

A terapêutica está, felizmente, em constante evolução e tal deve-se ao progresso da ciência e tecnologia. Do ponto de vista de quem prescreve, dispensa e utiliza medicamentos, esta evolução constante é mais percetível pelo posicionamento dos novos medicamentos nos algoritmos terapêuticos das diferentes patologias. Este posicionamento deriva do trabalho de diversos participantes, sendo que um dos principais é o ...
