Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

19.6K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Migration00:53

Migration

9.0K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Cell Migration01:19

Cell Migration

6.7K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell Migration

18.9K
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Bone Disorders01:29

Bone Disorders

5.6K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Disorders of Erythrocytes01:27

Disorders of Erythrocytes

2.4K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

    Summary
    This summary is machine-generated.

    Disorders of neuronal migration are linked to epilepsy, with cortical malformations often causing intractable seizures. Magnetic resonance imaging is crucial for diagnosing these brain development issues and guiding treatment.

    Area of Science:

    • Neuroscience
    • Developmental Biology
    • Neurology

    Background:

    • Enhanced understanding of brain development reveals strong links between neuronal migration disorders and seizure disorders.
    • A significant proportion of patients with intractable epilepsy exhibit cortical malformations stemming from abnormal neuronal migration.
    • These malformations are a key factor in the pathophysiology of certain epilepsy syndromes.

    Purpose of the Study:

    • To highlight the critical role of Magnetic Resonance Imaging (MRI) in diagnosing and classifying neuronal migration disorders.
    • To underscore the connection between cortical malformations and epilepsy.
    • To emphasize the ongoing advancements in imaging techniques for better patient outcomes.

    Main Methods:

    • Review of current literature on neuronal migration disorders and epilepsy.
    • Analysis of the diagnostic capabilities of Magnetic Resonance Imaging (MRI) in identifying cortical malformations.
    • Discussion of various types of neuronal migration disorders, including polymicrogyria, schizencephaly, lissencephaly, heterotopia, and focal cortical dysplasia.

    Main Results:

    • Magnetic Resonance Imaging (MRI) is the primary diagnostic tool for identifying and categorizing neuronal migration disorders.
    • Cortical malformations originating during neuronal migration are frequently associated with intractable epilepsy.
    • Specific disorders like polymicrogyria, schizencephaly, lissencephaly, heterotopia, and focal cortical dysplasia are recognized entities within this spectrum.

    Conclusions:

    • Neuronal migration disorders are significant contributors to seizure disorders, particularly intractable epilepsy.
    • Advanced Magnetic Resonance Imaging (MRI) techniques are essential for accurate diagnosis and classification.
    • Evolving imaging protocols aim to improve the assessment of anatomic and physiologic traits for enhanced seizure management.
