Feasibility of a ctDNA multigenic panel for non‐small‐cell lung cancer early detection and disease surveillance

open access: yesMolecular Oncology, EarlyView.
Plasma‐based detection of actionable mutations is a promising approach in lung cancer management. Analysis of ctDNA with a multigene NGS panel identified TP53, KRAS, and EGFR as the most frequently altered, with TP53 and KRAS in treatment‐naïve patients and TP53 and EGFR in previously treated patients.

Short term effects of irradiance on the growth of Pterocladiella capillacea (Gelidiales, Rhodophyta) [PDF]

open access: yes, 2019
Pterocladiella capillacea has been economically exploited for agar extraction in the Azores for many years. Harvesting dropped to a full stop in the early 1990s due to a population collapse, but restarted in 2013.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Liofilização: ciência ou arte? [PDF]

open access: yes, 2014
The freeze-drying (lyophilization) process is defined as a stabilizing process in which a substance is first frozen and then the quantity of the solvent (generally water) is reduced, first by sublimation and then desorption to values that will no longer ...

A subset of MMR‐proficient colon cancers responds to neoadjuvant immunotherapy

open access: yesMolecular Oncology, EarlyView.
Tan et al. reveal that a distinct subset of early‐stage pMMR colon cancers can respond to neoadjuvant immunotherapy. In the NICHE‐2 trial, responders (26%) were characterized by chromosomal instability, TP53 mutations, and proliferative cell‐cycle programs, whereas nonresponders showed metabolic and stromal reprogramming with TGF‐β‐driven ...

Protein O‐glycosylation in the Bacteroidota phylum

open access: yesFEBS 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.

Português, língua de ciência? [PDF]

open access: yes, 2016
Não é possível ignorar que para ter peso no panorama científico global, em muitas áreas, a divulgação tem de fazer do inglês o veículo fundamental. Esta imposição do inglês como única língua de ciência pode contribuir para uma menorização das outras ...

Contributo dos blogues de ciência para a construção da literacia científica cívica no século XXI [PDF]

open access: yes, 2013
Numa sociedade marcada pela superabundância de informação que exige, cada vez mais, o posicionamento crítico dos cidadãos, os blogues de ciência constituem um dos modos de interação possível para o debate de tópicos com relevância para um exercício de ...

Short‐term actions of epigalocatechin‐3‐gallate in the liver: a mechanistic insight into hypoglycemic and potential toxic effects

open access: yesFEBS Open Bio, EarlyView.
Epigallocatechin‐3‐gallate (EGCG) acutely inhibited gluconeogenesis and enhanced glycolysis, glycogenolysis, and fatty acid oxidation in perfused rat livers. Mechanistic assays revealed mitochondrial uncoupling, inhibition of pyruvate carboxylation and glucose‐6‐phosphatase, shift of NADH/NAD+ ratios toward oxidation, and loss of membrane integrity ...

Acerca de los "hábitos artificiales" en la antropología luliana y el ascenso espiritual del hombre [PDF]

open access: yes, 2005
The concept of "habitus artificialis" in lullian anthropology involves the knowledge of the divines virtues -the nature's secrets-, and it represents the spiritual way of human being. Similarly, some documents of medieval universities contain the natural
