Summary
Cell death mechanisms significantly impact tissue shrinkage. Cellular scale shrinkage is the primary driver of population-level changes, even with consistent cell death rates.
Area of Science:
- Biophysics
- Computational Biology
- Cell Biology
Background:
- Cell death is a complex process with varied outcomes at the tissue level.
- Understanding cell death's population-scale effects is crucial for fields like morphogenesis and cancer treatment.
- Current computational models lack robust methods to link cellular death to tissue-scale phenomena.
Purpose of the Study:
- To develop a mechanically robust agent-based model to simulate cell death's impact on population-scale tissue behavior.
- To investigate the mechanistic relationship between cellular scale changes during death and overall tissue shrinkage.
- To quantify model uncertainty and parameter interactions using sensitivity analysis.
Main Methods:
- Developed a mechanically robust agent-based cell model.
- Applied algorithmic rules at the cellular level to observe emergent population-scale effects.
- Implemented variance-based sensitivity analysis for stochastic model parameterization.
Main Results:
- Cellular scale shrinkage was identified as the most influential parameter affecting population shrinkage.
- Population shrinkage varied significantly based on cellular shrinkage, irrespective of the fraction of dying cells.
- Sensitivity analysis revealed key parameter interactions and model uncertainties.
Conclusions:
- The proposed agent-based model provides a framework for studying cell death's population-scale implications.
- Cellular shrinkage dynamics are critical determinants of tissue-level responses to cell death.
- Further research is needed to quantify diverse cell death mechanisms and their tissue-scale consequences.

01:27Shrinkage in Concrete
425
Shrinkage in concrete is primarily due to water loss from evaporation, hydration of cement, or carbonation, leading to a reduction in volume. The volumetric contraction results in volumetric strain in concrete. However, in practice, shrinkage is measured as linear strain, which is one-third of the volumetric strain.
When concrete is still in its plastic state, it can undergo a decrease in volume by about 1% of its absolute volume. This decrease is known as plastic shrinkage. It arises either...

01:21Drying Shrinkage
389
When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage.
A portion of this drying shrinkage can be reversed; if the concrete is...

01:24Carbonation Shrinkage
502
Atmospheric CO2 penetrates the concrete's pores and, in the presence of moisture, forms carbonic acid, which then reacts with calcium hydroxide in the hydrated cement, forming calcium carbonate. This process reduces the concrete's volume and is termed carbonation shrinkage.
The concrete's permeability is slightly reduced as calcium carbonate produced during the reaction fills its pores. Furthermore, its strength is slightly enhanced as the water released during the reaction...

01:18Autophagic Cell Death
4.6K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
