Blocking the voltage‐gated sodium channel hNav1.5 as a novel pH‐dependent mechanism of action for tamoxifen

open access: yesFEBS Open Bio, EarlyView.
Patch‐clamp recordings revealed that tamoxifen inhibits voltage‐gated sodium channels, especially under acidic conditions, both common in metastatic cancer cells. These effects may explain certain antitumor properties of tamoxifen, highlighting a novel mechanism of action beyond its known endocrine effects.

Osmotic pressure‐induced calcium response states

open access: yesFEBS Open Bio, EarlyView.
Acute hypotonic stress triggers distinct calcium response patterns in HEK293T cells. These signals originate from the endoplasmic reticulum via RyR2 and propagate to neighboring cells through gap junctions. This result highlights a novel calcium‐dependent mechanism underlying the intracellular and intercellular response to osmotic pressure.

Teaching Python with team‐based learning: using cloud‐based notebooks for interactive coding education

open access: yesFEBS Open Bio, EarlyView.
This study presents a novel approach to teaching Python and bioinformatics using team‐based learning and cloud‐hosted notebooks. By integrating interactive coding into biomedical education, the method improves accessibility, student engagement, and confidence—especially for those without a computing background.

Computerized brain tumor segmentation in magnetic resonance imaging

open access: yesEinstein (São Paulo), 2012
OBJECTIVE: To propose an automatic brain tumor segmentation system. METHODS: The system used texture characteristics as its main source of information for segmentation. RESULTS: The mean correct match was 94% of correspondence between the segmented areas

Most autophagic cell death studies lack evidence of causality

open access: yesFEBS Open Bio, EarlyView.
Of 104 studies claiming autophagic cell death (ACD), only 13 demonstrated both causality and exclusion of apoptosis to confirm true ACD. Most studies relied on correlation‐level data or measured autophagy in isolation, revealing pervasive methodological shortcomings.

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

open access: yesFEBS Open Bio, EarlyView.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.

Transcriptional regulation of neuropeptide receptors underlies context‐dependent adaptation in Drosophila melanogaster

open access: yesFEBS Open Bio, EarlyView.
Under environmental changes, the expression level of neuropeptide (NP) and neuropeptide receptor (NPR) genes changes to confer context‐dependent adaptation to the model organism Drosophila melanogaster. Through finding more regulatory elements in the NPR genes in comparison with their ligands (NPs), we found that NPR‐biased transcriptional regulation ...

[Computer-assisted image processing for quantifying histopathologic variables in the healing of colonic anastomosis in dogs].

open access: yesRevista da Associacao Medica Brasileira (1992), 1998
The authors present the experimental results of the computerized quantifying of tissular structures involved in the reparative process of colonic anastomosis performed by manual suture and biofragmentable ring. The quantified variables in this study were: oedema fluid, myofiber tissue, blood vessel and cellular nuclei.An image processing software ...

A unified model for Duchenne muscular dystrophy gene involvement in cancer: context‐dependent tumour suppression and oncogenicity

open access: yesFEBS Open Bio, EarlyView.
We propose a context‐dependent model where the Duchenne muscular dystrophy (DMD) gene acts as a tumour suppressor in aggressive tumours and as an oncogene in less aggressive ones. We propose this model as a unified framework to explain the opposing survival associations with DMD expression and to guide experimental exploration of the dual role of DMD ...
