Summary
This study determined the mechanical properties of the human placenta using experimental data and finite element analysis. The identified hyper-viscoelastic parameters offer a new approach to modeling placental biomechanics.
Area of Science:
- Biomedical Engineering
- Materials Science
- Reproductive Biology
Context:
- The mechanical properties of the human placenta are crucial for understanding its function during pregnancy.
- Previous models have not fully captured the complex biomechanical behavior of placental tissue.
Purpose:
- To determine the mechanical properties of the human placenta.
- To develop and validate a hyper-viscoelastic model for placental tissue behavior.
Summary:
- An experimental study involving 80 human placentas was conducted.
- A finite element numerical model was developed using inverse analysis to identify material parameters.
- The Ogden hyper-viscoelastic model was optimized, yielding specific material parameters (mu and alpha values) for static conditions.
Impact:
- The determined parameters provide a quantitative understanding of placental mechanical behavior.
- These parameters can be integrated into numerical models for further research and potential clinical applications.
- This research advances the field of biomechanics in obstetrics and gynecology.

00:54What is Behavior?
10.3K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Chemical reactions often occur in a stepwise fashion, involving two or more distinct reactions taking place in a sequence. A balanced equation indicates the reacting species and the product species, but it reveals no details about how the reaction occurs at the molecular level. The reaction mechanism (or reaction path) provides details regarding the precise, step-by-step process by which a reaction occurs.
For instance, the decomposition of ozone appears to follow a mechanism with two steps:

01:58Mechanical Protein Functions
5.7K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

02:37Experimental Determination of Chemical Formula
47.5K
The elemental makeup of a compound defines its chemical identity, and chemical formulas are the most concise way of representing this elemental makeup. When a compound’s formula is unknown, measuring the mass of its constituent elements is often the first step in determining the formula experimentally.

7.7K
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
