Coat Assembly and GTPases01:33

Coat Assembly and GTPases

4.1K
Vesicles incorporate different coat protein subunits in different cell locations, which changes the properties of the coat, such as the shape and geometry of the transport vesicles. Thus, vesicle coat proteins also play a significant role in cargo selection.
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...

Incomplete Dominance01:43

Incomplete Dominance

29.1K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

1.7K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

8.7K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Cardiomyopathy II: Dilated Cardiomyopathy

257
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Epistasis01:39

Epistasis

49.3K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

    Summary

    Coats disease, a rare retinal vascular disorder, typically affects young individuals. Neglected treatment in a pediatric patient revealed the disease's natural, progressive course.

    Area of Science:

    • Ophthalmology
    • Retinal Vascular Diseases
    • Pediatric Ophthalmology

    Background:

    • Coats disease is a rare, non-hereditary retinal vascular abnormality.
    • It is characterized by idiopathic retinal telangiectasia and progressive exudation.
    • The condition typically presents in the first two decades of life.

    Purpose of the Study:

    • To describe the natural course of Coats disease.
    • To highlight the consequences of neglected treatment in a pediatric patient.

    Main Methods:

    • Case report of a pediatric patient with Coats disease.
    • Observation of the disease progression without intervention due to family neglect.

    Main Results:

    • The patient's Coats disease followed a progressive course.

  • Neglected treatment allowed for the observation of the natural disease trajectory.

    • Conclusions:

    • Coats disease can have significant progression when left untreated.
    • This case underscores the importance of timely medical intervention for retinal vascular abnormalities.
