ESR1 methylation and ESR1 mutations in circulating tumor cells (CTCs) and paired plasma‐cfDNA of advanced breast cancer patients: A feasibility proof‐of‐concept study

open access: yesMolecular Oncology, EarlyView.
Circulating tumor cells (CTCs) and plasma cell‐free DNA (cfDNA) were analyzed to detect ESR1 mutations and methylation in patients with advanced breast cancer. CTC‐derived DNA showed higher sensitivity for mutation detection and revealed complementary genetic and epigenetic alterations, highlighting the added value of CTC analysis for understanding ...

Deformation and Resistivity Characteristics of Compacted Loess Under Dry–Wet Cycles

open access: yesGeosciences
Compacted loess is widely used as road subgrade filling in northwestern China, but its stability is threatened by traffic loads and repeated dry–wet cycles, leading to subgrade settlement or collapse.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

open access: yesMolecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

open access: yesMolecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Improved Grammar-Based Compressed Indexes [PDF]

open access: yes, 2012
We introduce the first grammar-compressed representation of a sequence that supports searches in time that depends only logarithmically on the size of the grammar. Given a text $T[1..u]$ that is represented by a (context-free) grammar of $n$ (terminal and nonterminal) symbols and size $N$ (measured as the sum of the lengths of the right hands of the ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Sustainable prediction of compression index in fine-grained soils using machine learning techniques

open access: yesOpen Geosciences
The accurate prediction of ultimate settlement is of critical importance for the longevity of structures, as it helps prevent structural damage and functional deterioration.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

open access: yesFEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

About Graph Index Compression Techniques [PDF]

open access: yes, 2019
We perform a preliminary study on large graph efficient indexing using a gap-based compression techniques and different node labelling functions. As baseline we use the Webgraph + LLP labelling function. To index the graph we use three labelling functions: Pagerank, HITS, and Pagerank with random walks choosing restart nodes with HITS authority scores.

Heterogeneidade da compactação de um latossolo vermelho-amarelo sob pomar de laranja Compaction heterogeneity of a haplustox under an orange orchard

open access: yesRevista Brasileira de Ciência do Solo, 2004
A heterogeneidade na compactação do solo, provocada por diferentes intensidades de tráfego, pode limitar a produção em áreas citrícolas. O objetivo deste trabalho foi quantificar o índice de compressão (IC) e a pressão de preconsolidação (sigmap) nas ...
