Histone Modification02:32

Histone Modification

16.3K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Spreading of Chromatin Modifications02:25

Spreading of Chromatin Modifications

9.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Behavior Modification01:21

Behavior Modification

754
Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.
A real-world application of operant conditioning principles is applied...

Force Classification01:22

Force Classification

2.5K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

    Area of Science:

    • Orthopedics
    • Sports Medicine
    • Foot and Ankle Surgery

    Background:

    • Lisfranc injuries are uncommon, with subtle cases frequently missed during initial diagnosis.
    • Missed Lisfranc injuries are a significant cause of medical litigation.
    • These injuries can result from both high-energy trauma and lower-energy indirect mechanisms, particularly in athletic settings.

    Purpose of the Study:

    • To provide a topical review of subtle Lisfranc injuries.
    • To focus on contemporary perspectives regarding these injuries.
    • To describe a modification to the existing classification system for Lisfranc disruptions.

    Main Methods:

    • Literature review of subtle Lisfranc injuries.
    • Analysis of contemporary perspectives and diagnostic challenges.
    • Description of a proposed modification to a prevalent classification system.

    Main Results:

    • Subtle Lisfranc injuries are underreported, with approximately one-third missed on initial evaluation.
    • High-energy and lower-energy indirect mechanisms contribute to Lisfranc disruptions.
    • A modified classification system for Lisfranc injuries is presented.

    Conclusions:

    • Early and accurate diagnosis of subtle Lisfranc injuries is crucial to prevent litigation.
    • Understanding diverse injury mechanisms is key for diagnosis.
    • The proposed classification modification aims to improve the management of Lisfranc disruptions.
