Molecular Oncology, EarlyView.Detection of extrachromosomal circular DNA (eccDNA) in plasma samples from EGFR‐mutated non‐small cell lung cancer patients. Plasma was collected before and during treatment with the EGFR‐tyrosine kinase inhibitor osimertinib. Plasma eccDNA was detected in all cancer samples, and the presence of the EGFR gene on eccDNA serves as a potential biomarker ...

Introducción a la artillería de torsión
Gladius, 2011 La artillería de torsión grecorromana es un campo tan apasionante como poco estudiado en la bibliografía española. Del siglo IV a.C. al VI d.C., la evolución de este tipo de armamento —diseñado para lanzar dardos o piedras— está jalonada de hallazgos ...

Estudio del efecto de la silice coloidal sobre la resistencia de un hilado. [PDF]
, 1963 Se determina la resistencia que corresponde a ambos hilados bajo distintos estados de torsión, con el fin de establecer hasta qué punto la influencia de la sílice coloidal es de importancia bajo un punto de vista industrial en el caso que aquí ...

FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Adnexal torsion: is there a familial tendency?
Clinical and Experimental Obstetrics & Gynecology, 2020 Objective: To investigate whether patients diagnosed with adnexal torsion report a family history of adnexal torsion in a first degree relative. Materials and Methods: All women with a surgical diagnosis of adnexal torsion operated from 2008 to 2016 were

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

La Influencia de Élie Cartan sobre la obra de Albert Einstein [PDF]
, 2014 Sin Élie Cartan, las matemáticas y la física del siglo XX serían muy distintas de las que conocemos, especialmente en relación con el intento de Einstein de construir una teoría de campo unificado. Cartan introdujo la noción de "tétrada’" o vielbein, que

Advanced Engineering Materials, EarlyView.In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Advanced Engineering Materials, EarlyView.Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.
