Da assistência aos pobres aos cuidados de saúde primários em Portugal: o papel da enfermagem: 1926-2002
RESUMO - Este estudo analisa a forma como os cuidados de saúde não hospitalares e a enfermagem
comunitária, se desenvolveram e se influenciaram mutuamente, no período 1926-2002. Trata-se de
um estudo histórico que recorre a fontes escritas, imagéticas e orais, e utiliza conceções do novo
institucionalismo e os conceitos de poder e biopoder de Foucault, para investigar este processo.
Apresenta e analisa as origens destes cuidados e da enfermagem comunitária, o modo como se
institucionalizaram e como evoluíram. A criação e desenvolvimento dos cuidados de saúde não
hospitalares foram acompanhados pela individualização da enfermagem comunitária. As políticas e
práticas dos cuidados de saúde primários e da enfermagem comunitária apresentam uma clara
dependência do percurso já realizado.
A sua génese está ligada a práticas de caridade cristã de assistência aos mais pobres
liderada pelas Misericórdias e ordens religiosas. O novo entendimento sobre o papel do Estado
relativamente à saúde conduziu à criação de instituições não hospitalares e à diferenciação da
enfermagem comunitária. Assinale-se como momentos positivos para enfermeiros e instituições a
formação das visitadoras sanitárias, apoio à formação em saúde pública pela Fundação Rockefeller,
a criação de instituições corporativas, privadas e públicas de cuidados não hospitalares, a reforma
de 1971 e o movimento dos CSP. As políticas institucionais condicionaram o próprio
desenvolvimento e o da enfermagem comunitária, devido aos estereótipos associados ao papel da
mulher, à multiplicidade e disparidade de formações e às visões divergentes sobre o que era a
enfermagem comunitária. Este processo de desenvolvimento entretecido entre enfermagem
comunitária e CSP apresenta influências e contributos mútuos. Os cuidados de saúde não
hospitalares proporcionaram aos enfermeiros formação, desenvolvimento profissional, oportunidade
de uma intervenção diversificada e com elevado grau de autonomia. Já estes trouxeram
aproximação à comunidade, atenção especial aos mais vulneráveis, criatividade, capacidade de
adaptação perante condições adversas, contribuindo para a visibilidade e relevância afetiva dos
CSP.ABSTRACT - This study examines how primary healthcare and community nursing, developed and
influenced each other, over the period from 1926 to 2002. It is a historical study and uses
conceptions of the new institutionalism and the concepts of power and biopower of Foucault, to
investigate this process. The aim of this study is to analyze the origins and development of primary
healthcare and community nursing, how they became institutionalized and evolved. The creation of
primary healthcare was followed by individualization of community nursing. The policies and
practices of primary health care and community nursing show clear path dependence.
Its origins are linked to the practice of Christian charity to assist the poor, led by
“Misericórdias” and religious orders. The new understanding about the role of the State in relation to
healthcare led to the creation of primary healthcare services and the differentiation of community
nursing. The visiting nurses education, supporting training in public health by the Rockefeller
Foundation, the creation of corporate, private and public primary healthcare services, the 1971
reform and the movement of primary healthcare, were positive marks for the nurses and institutions.
The institutional policies conditioned the community nursing and primary healthcare, due to
the stereotypes associated with the role of women, the multiplicity and disparity of backgrounds and
divergent conceptions about community nursing. This development process reveals influences and
multiple contributions. The primary healthcare provided training to nurses, professional development,
and an opportunity for a diversified intervention with a high degree of autonomy. On the other hand,
the nurses brought concern to the vulnerable and poor people, creativity, and adaptability against
adverse conditions, contributing to the visibility and affective relevance of primary healthcare
Synthesis of novel psoralen analogues and their in vitro antitumor activity
New tetracyclic benzofurocoumarin (benzopsoralen) analogues were synthesized and their inhibitory effect on the growth of tumor cell lines was evaluated. The human tumor cell lines used were MDA MB231 (breast adenocarcinoma), HeLa (cervix adenocarcinoma) and TCC-SUP (bladder transitional cell carcinoma). The in vitro antitumor activity of the new benzopsoralens was discussed in terms of structure–activity relationship. Molecular docking studies with human-CYP2A6 enzymes were also carried out with the synthesized compounds in order to evaluate the potential of these compounds to interact with the heme group of the enzymes. The results have demonstrated that the linear compounds have the most pronounced activity against tumor cell lines and this might be related to the better accessibility that these compounds have to the active site in relation to the angular ones that have shown in the majority of the cases multiple binding poses in the active site of CYP2A6.To the Foundation for the Science and Technology (FCT, Portugal) for financial support to the NMR portuguese network (PTNMR, Bruker Avance III 400-Univ.

Cork oak forests soil bacteria: potential for sustainable agroforest production
Plant growth promoting rhizobacteria (PGPR) are in increasing demand due to their role in promoting sustainable practices, not only in agriculture but also in forestry. Keeping in mind the future application of PGPR for increasing cork oak sustainability, the aim of this study was to find cork oak PGPR isolates with increased nutrient solubilisation traits, able to promote root morphological changes and/or antagonize cork oak bark phytopathogens. Soils from three cork oak forests with distinct bioclimates (humid, semi-humid and semi-arid) were used for isolating bacteria. From the 7634 colony-forming units, 323 bacterial isolates were biochemically assayed for PGPR traits (siderophores production, phosphate solubilizing and organic acids production), and 51 were found to display all these traits. These PGPR were able to induce root morphological changes on Arabidopsis thaliana, like suppression of primary root growth, increase of lateral roots or root hairs formation. However, the most proficient PGPR displayed specific ability in changing a single root morphological trait. This ability was related not only to bacterial genotype, but also with the environment where bacteria thrived and isolation temperature. Bacteria from semi-arid environments (mainly Bacillus megaterium isolates) could hold a promising tool to enhance plant development. Other isolates (Serratia quinivorens or B. cereus) could be further explored for biocontrol purposes.This work was supported by FEDER funds through COMPETE (Programa Operacional Factores de Competitividade) and by national funds by FCT (Fundação para a Ciência e a Tecnologia) in

Novel benzopsoralen analogues : synthesis, biological activity and molecular docking studies
New benzopsoralen analogues were synthesized and their inhibitory effect on the growth of tumourtumour cell lines (MDA MB231 and TCC-SUP) was evaluated. The in vitro antitumour activity of the new benzopsoralen analogues was discussed in terms of structure–activity relationship. Molecular docking studies with human-CYP2A6 enzymes were also carried out with the synthesized compounds to evaluate the potential of these molecules to interact with the haem group of the enzymes. The results demonstrated that the compounds that are able to interact with the iron ion of the haem cofactor and at the same time with active site Asn297 are those that have better anti-proliferative activity.To the Foundation for the Science and Technology (FCT, Portugal) for financial support to the NMR Portuguese network (PTNMR, Bruker Avance III 400-Univ.

Data on European seabass fed with methionine-enriched diets obtained through label free shotgun proteomics
This data article is associated with the research article "Evaluating the impact of methionine-enriched diets in the liver of European seabass through label-free shotgun proteomics". Here it is described the data obtained from proteomic analysis of 36 European seabass juveniles (3 fish x 3 replicate tanks) after 18 days of feeding with experimental diets containing four inclusion levels of methionine (Met): 0.77%, 1%, 1.36% and 1.66% Met (w/w). We analysed this dataset and compared it with that obtained during the long-term feeding period i.e., 85 days. Fish liver proteins were digested with trypsin and purified peptides were analysed by LC-MS/MS. Proteins were identified with at least two peptides at 0.1% Decoy false discovery rate (FDR). In this dataset, we present the analysis of the differential abundant proteins (DAP) with significant differences across treatments after 18 days of feeding (One-Way ANOVA, p < 0.05). Treatment's comparisons were also performed between the 18- and 85-days feeding trials through Two-Way ANOVA (p < 0.05). MS/MS raw data are available via ProteomeXChange with identifiers PXD019610 and 10.6019/PXD019610 (18-days dataset); and PXD019622 and 10.6019/PXD019622 (85-days dataset). This dataset corresponds to fish sampled after 18-days of experimental trial and is made available to support the study conducted in the afore-mentioned article, by performing the analysis during a short-term period of feeding. The data presented may be further used in other nutritional studies e.g., addressing hepatic changes mediated by Met.ALG-01-0247-FEDER-3520/ UIDB/04326/2020/ IF/00482/2014/CP1217/CT0005info:eu-repo/semantics/publishedVersio
New magnetogels based on manganese ferrite nanoparticles and self-assembled peptide hydrogels as drug nanocarriers
In this work, superparamagnetic manganese ferrite (MnFe2O4) nanoparticles were successfully incorporated in self-assembled peptide-derived hydrogels. The new magnetogels were tested as nanocarriers for two fluorescent drugs, curcumin (an anticancer and neuroprotective drug) and a new antitumor thienopyridine derivative. Fluorescence-based techniques (fluorescence emission, FRET and fluorescence anisotropy) were used to assess incorporation of these drugs in the magnetogels and their transport towards models of biological membranes. It can be observed that the drug moves to the model membranes upon interaction of the drug-loaded magnetogels with membranes.This work was supported by the Portuguese Foundation for Science and Technology (FCT) in the framework of the Strategic Funding of CF-UM-UP (UID/FIS/04650/2013) and of CQ-UM (UID/QUI/00686/2013).

Novel scFv against Notch Ligand JAG1 Suitable for Development of Cell Therapies toward JAG1-Positive Tumors
Funding Information: This research was funded by the Fundação para a Ciência e Tecnologia/Ministério da Ciência, Tecnologia e Ensino Superior (FCT/MCTES, Portugal) grant PTDC/BBB-BMD/4497/2014 (to A.B.), through national funds to iNOVA4Health (UIDB/04462/2020 and UIDP/04462/2020), and the Associate Laboratory LS4FUTURE (LA/P/0087/2020). Publisher Copyright: © 2023 by the authors.The Notch signaling ligand JAG1 is overexpressed in various aggressive tumors and is associated with poor clinical prognosis. Hence, therapies targeting oncogenic JAG1 hold great potential for the treatment of certain tumors. Here, we report the identification of specific anti-JAG1 single-chain variable fragments (scFvs), one of them endowing chimeric antigen receptor (CAR) T cells with cytotoxicity against JAG1-positive cells. Anti-JAG1 scFvs were identified from human phage display libraries, reformatted into full-length monoclonal antibodies (Abs), and produced in mammalian cells. The characterization of these Abs identified two specific anti-JAG1 Abs (J1.B5 and J1.F1) with nanomolar affinities. Cloning the respective scFv sequences in our second- and third-generation CAR backbones resulted in six anti-JAG1 CAR constructs, which were screened for JAG1-mediated T-cell activation in Jurkat T cells in coculture assays with JAG1-positive cell lines. Studies in primary T cells demonstrated that one CAR harboring the J1.B5 scFv significantly induced effective T-cell activation in the presence of JAG1-positive, but not in JAG1-knockout, cancer cells, and enabled specific killing of JAG1-positive cells. Thus, this new anti-JAG1 scFv represents a promising candidate for the development of cell therapies against JAG1-positive tumors.publishersversionpublishe
