Modifying factors of PD‐L1 expression on tumor cells in advanced non‐small‐cell lung cancer

open access: yesThoracic Cancer, Volume 13, Issue 23, Page 3362-3373, December 2022., 2022
Programmed death ligand‐1 (PD‐L1) is an essential biomarker guiding treatment in nononcogene addicted advanced lung adenocarcinoma, and many factors may impact its reproducibility and performance. This study demonstrated an increased probability of identifying PD‐L1‐positive samples in poorly differentiated, solid predominant, and EGFR wild‐type tumors.

On the (n,k)-th Catalan numbers [PDF]

open access: yesCommun. Korean Math. Soc. 23(3) (2008) 349-356, 2015
In this paper, we generalize the Catalan number to the $(n,k)$-th Catalan numbers and find a combinatorial description that the $(n,k)$-th Catalan numbers is equal to the number of partitions of $n(k-1)+2$ polygon by $(k+1)$-gon where all vertices of all $(k+1)$-gons lie on the vertices of $n(k-1)+2$ polygon.

Core‐Twisted, Cationic Perylene Diimides; Homochiral Dimerisation and Chiroptical Anion Sensing

open access: yesChemistry – A European Journal, Accepted Article.
Core‐twisted perylene diimides are chiral organic dyes that may be exploited for self‐assembled chiroptical materials or for the enantioselective recognition and sensing of chiral substrates. Discrete self‐assembled dimers and host–guest complexes of core‐twisted perylene diimides are important for furthering our understanding of this supramolecular ...

Cysteine restriction‐specific effects of sulfur amino acid restriction on lipid metabolism

open access: yesAging Cell, Volume 21, Issue 12, December 2022., 2022
The proposed mechanism of CR‐specific effects of SAAR on adipose metabolism. (1) Due to the lack of Cys in SAAR diets, it imposes both MR and CR. CR specifically results in decreased biosynthesis of the tripeptide glutathione. (2) Lower hepatic glutathione increases the abundance of the transcription factor Nrf2, which translocates to the nucleus and ...

La geolingüística catalana, ahir i avui

open access: yesCaplletra: Revista Internacional de Filologia, 2015
After surveying a number of books on geolinguistics which have completely or partially focused on the Catalan language from the seventies, this paper points out the importance of continental atlases and linguistic research groups to the development of ...

Determination of Boron Content in Surface Paintings From Historical Stained‐Glass Windows

open access: yesChemistry–Methods, EarlyView.
The present work validates the use of LIBS as an analytical technique for in‐situ qualitative and quantitative determination of boron content in enamels and historical glass samples and provides information on in‐depth possible changes in the chemical composition induced by corrosion effects.

Exploring Semanticity for Content and Function Word Distinction in Catalan

open access: yesLanguages
In the realm of linguistics, the concept of “semanticity” was recently introduced as a novel measure designed to study linguistic networks. In a given text, semanticity is defined as the ratio of the potential number of meanings associated with a word to

Access to Highly Functional and Polymerizable Carbonate‐Drug Conjugates

open access: yesChemSusChem, EarlyView.
A generic protocol for drug‐functionalized and carbon dioxide‐based six‐membered cyclic carbonates has been developed. These functional carbonates can be designed for effective ring‐opening polymerization to forge polycarbonates that support a controllable amount of a given drug and additional functionality, opening up complementary strategies for ...
