Common Ion Effect

Common Ion Effect

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Multiple Comparison Tests

Multiple Comparison Tests

Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Common Respiratory Disorders

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Genomics
Systems Biology
Neuroscience

Background:

Understanding common molecular interactions across samples is crucial for deciphering diseases and biological processes.
Gene coexpression networks and their modules represent sample-specific gene interactions.
Identifying commonalities in these networks can illuminate disease mechanisms and biological relationships.

Purpose of the Study:

To propose quantitative comparison methods for coexpression networks.
To identify common biological mechanisms between Huntington's disease and brain aging using these new methods.

Main Methods:

Developed two novel similarity measures for quantitative comparison of coexpression networks.
Validated the measures through experiments with known coexpression networks and evaluated optimal threshold values.
Applied the similarity measures to identify common coexpression modules between Huntington's disease and brain aging.

Main Results:

Successfully proposed and validated two quantitative similarity measures for coexpression networks.
Identified specific pairs of coexpression modules common to Huntington's disease and brain aging.
Determined optimal threshold values for identifying similar coexpression network pairs.

Conclusions:

Identified shared coexpression modules between Huntington's disease and brain aging.
These common modules are associated with brain development, cell death, and immune responses.
Suggests that dysregulated cell signaling in cell death and immune/inflammation responses are potential common molecular mechanisms in both conditions.
