Modeling and Evaluation of Penetration Process Based on 3D Mechanical Simulation

Sensors
In biological micromanipulation, cell penetration is a typical procedure that precedes cell injection or oocyte enucleation. During this procedure, cells usually undergo significant deformation, which leads to cell damage.

Curricular tracking and civic and political engagement: Comparing adolescents and young adults across education systems

Acta Sociologica, 2019
Country-case studies examining the relation between curricular tracking (ability sorting) in secondary education and civic and political engagement (CPE) have led to mixed findings. This calls for a comparative approach.

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

Population Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

A novel perspective on the regulation of cardiac cell beating: cardiac cell under mechanical stimulation acts as “cell activation button” to activate adjacent cardiac cell

Journal of Nanobiotechnology
The regulation of cardiac cell beating is of great significance for understanding cardiac coordination mechanisms and the treatment of cardiovascular diseases.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

A large‐scale retrospective study in metastatic breast cancer patients using circulating tumour DNA and machine learning to predict treatment outcome and progression‐free survival

Molecular Oncology, EarlyView.
There is an unmet need in metastatic breast cancer patients to monitor therapy response in real time. In this study, we show how a noninvasive and affordable strategy based on sequencing of plasma samples with longitudinal tracking of tumour fraction paired with a statistical model provides valuable information on treatment response in advance of the ...
