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.

The Clinician–Educator Track

Academic Medicine, 2014
Although resident-as-teacher programs bring postgraduate trainees' teaching skills to a minimum threshold, intensive, longitudinal training is lacking for residents who wish to pursue careers in medical education. The authors describe the development, implementation, and preliminary assessment of the novel track for future clinician-educators that they

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

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.

Efficient Two-Stage Autofocus for Micro-Assembly Based on Joint Spatial-Frequency Image Quality Assessment

Journal of Imaging
Reliable autofocus is a fundamental prerequisite for precise positioning in micro-assembly systems, where complex reflections, scale variations, and narrow depth-of-field often degrade the robustness of traditional sharpness metrics.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Robotic cell transportation system based on micropipette resistance modeling

Microsystems & Nanoengineering
Cell transportation, using a micropipette to pick and place cells from one droplet to another, is a key step in many cell engineering applications. However, most of the current cell transportation operations rely on microscope vision guidance, unsuitable
