DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Allosteric Proteins-ATCase

5.7K
Binding sites linkages can regulate a protein's function.  For example, enzyme activity is often regulated through a feedback mechanism where the end product of the biochemical process serves as an inhibitor.
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to  N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis...

Changes in Skin Color: Clinical Perspectives

1.7K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

5.7K
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

    Area of Science:

    • Metabolic Disorders
    • Rheumatology
    • Genetics

    Background:

    • Alkaptonuria (AKU) is a rare autosomal recessive metabolic disorder.
    • It results from homogentisic acid oxidase deficiency, leading to homogentisic acid accumulation.
    • Characterized by homogentisic aciduria, ochronosis, and arthropathy.

    Purpose of the Study:

    • To present a case of severe ochronotic arthritis managed with total joint replacement.
    • To evaluate the efficacy of joint replacement in relieving pain and improving function in AKU patients.

    Main Methods:

    • Case report of a middle-aged female patient with bilateral hip and shoulder ochronotic arthritis.
    • Staged total joint replacement procedures performed for hip and shoulder joints.
    • Assessment of clinical and functional outcomes post-surgery.

    Main Results:

    • The patient underwent successful bilateral hip and shoulder replacements without complications.
    • Complete pain relief and satisfactory clinical and functional outcomes were achieved.
    • Demonstrates the effectiveness of total joint replacement in severe ochronotic arthropathy.

    Conclusions:

    • Ochronosis, a complication of AKU, can lead to severe peripheral joint arthropathy.
    • Multiple joint involvement is frequently observed in ochronotic arthropathy.
    • Total joint replacement offers a viable solution for persistent pain and functional recovery in severe cases.
