O Debate Multicultural no �?â??mbito das Ciências da Religião

Caminhos, 2008
Interessa-nos, nesta reflexão, analisar a religião a partir de sua relação com os paradigmas do multiculturalismo e suas implicações na formulação de demandas que tem a ver com as Ciências da Religião.

Serodiagnóstico da túberculose. O valor dos antigénios glicolipídicos, do antigénio A60 e do P.P.D. no diagnóstico da tubérculose**2a Parte da Aula de Agregação apresentada a Faculdade de Ciências Médicas da Universidade Nova de Lisboa

Revista Portuguesa de Pneumologia, 1996
RESUMO: Neste trabalho, em face dos resultados promissores obtidos com os antigénios glicolipídicos no diagnóstico do Mycobacterium tuberculosis, avaliámos a sensibilidade e especificidade de 2 antigénios protei-cos, o Antigénio 60 e o PPD e três antigénios glicolipídicos: diaciltrialose (D.A.), sulfolipido 1 (SLI) e fenolglicolípido da ...

Spot‐14 and its paralog Spot‐14R regulate expression of metabolic and thermogenic pathway genes in murine brown and beige adipocytes

FEBS Letters, EarlyView.
Spot‐14 and Spot‐14R play distinct roles in regulating metabolism in brown and beige adipocytes. While both influence lipid and glucose pathways, Spot‐14 uniquely controls thermogenic gene expression. This dual regulation balances energy storage and heat production, highlighting potential therapeutic targets for obesity and metabolic disorders. Spot 14

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

FEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

A stepwise emergence of evolution in the RNA world

FEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Protein O‐glycosylation in the Bacteroidota phylum

FEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

Neurotoxic amyloid β‐peptide and tau produce cytokine‐like effects on PMCA in glioblastoma cell lines, enhancing its activity and isoforms expression

FEBS Open Bio, EarlyView.
Two biomarkers of Alzheimer's disease, amyloid β‐peptide (Aβ) and tau, induce the transformation of U‐251 and other glioblastoma cell lines into neurotoxic A1‐like reactive astrocytes. This transformation is produced by cytokines and is followed by upregulation of PMCA activity and isoform expression, and is closely associated with inflammation, as ...

ciencia respeito a natureza e bem estar humano

Scientiae Studia, 2008
A questão central aqui levantada é a seguinte: de que maneira a pesquisa científica deve ser conduzida de modo a assegurar que a natureza seja respeitada - que suas potencialidades regenerativas não sejam ulteriormente solapadas, e que sejam restabelecidas onde quer que seja possível - e que o bem-estar de todos, em todos os lugares, possa ampliar-se ...
