Etoposide‐induced cancer cell death: roles of mitochondrial VDAC1 and calpain, and resistance mechanisms

open access: yesMolecular Oncology, EarlyView.
The complex mode of action of the topoisomerase II inhibitor etoposide in triggering apoptosis involves several mechanisms: overexpression of the mitochondrial protein VDAC1, leading to its oligomerization and formation of a large channel that mediates the release of pro‐apoptotic protein; and overexpression of the apoptosis regulators p53, Bax, and ...

Cultures of Optimism [PDF]

open access: yesCultural Sociology, 2011
Drawing on material from a broad range of fields, this article identifies an ‘optimism of everyday life’ and proposes that it performs significant psychological, social and cultural functions. These functions are briefly reviewed, with particular reference to psychological and physical health, family and social relationships and the achievement of ...

Response to neoadjuvant chemotherapy in early breast cancers is associated with epithelial–mesenchymal transition and tumor‐infiltrating lymphocytes

open access: yesMolecular Oncology, EarlyView.
Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

Fast EM-driven nature-inspired optimization of antenna input characteristics using response features and variable-resolution simulation models

open access: yesScientific Reports
Utilization of optimization technique is a must in the design of contemporary antenna systems. Often, global search methods are necessary, which are associated with high computational costs when conducted at the level of full-wave electromagnetic (EM ...

Multiplex single‐cell profiling of putative cancer stem cell markers ALDH1, SOX9, SOX2, CD44, CD133 and CD15 in endometrial cancer

open access: yesMolecular Oncology, EarlyView.
Cancer stem cells are associated with aggressive disease, but a deep characterization of such markers is lacking in endometrial cancer. This study uses imaging mass cytometry to explore putative cancer stem cell markers in endometrial tumors and corresponding organoid models.

Storage capacity allocation strategy for distribution network with distributed photovoltaic generators

open access: yesJournal of Modern Power Systems and Clean Energy, 2018
Distributed photovoltaic generators (DPGs) have been integrated into the medium/low voltage distribution network widely. Due to the randomness and fluctuation of DPG, however, the distribution and direction of power flow are changed frequently on some ...

Stochastic variation in the FOXM1 transcription program mediates replication stress tolerance

open access: yesMolecular Oncology, EarlyView.
Cellular heterogeneity is a major cause of drug resistance in cancer. Segeren et al. used single‐cell transcriptomics to investigate gene expression events that correlate with sensitivity to the DNA‐damaging drugs gemcitabine and prexasertib. They show that dampened expression of transcription factor FOXM1 and its target genes protected cells against ...

ePyDGGA: automatic configuration for fitting epidemic curves

open access: yesScientific Reports
Many epidemiological models and algorithms are used to fit the parameters of a given epidemic curve. On many occasions, fitting algorithms are interleaved with the actual epidemic models, which yields combinations of model-parameters that are hard to ...

Efficient Gradient-Enhanced Bayesian Optimizer with Comparisons to Quasi-Newton Optimizers for Unconstrained Local Optimization [PDF]

open access: yesarXiv
The probabilistic surrogates used by Bayesian optimizers make them popular methods when function evaluations are noisy or expensive to evaluate. While Bayesian optimizers are traditionally used for global optimization, their benefits are also valuable for local optimization.
