Disorders of Erythrocytes

2.8K
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.

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

2.8K
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...

iPS Cell Differentiation01:22

iPS Cell Differentiation

3.3K
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Area of Science:

  • Hematology
  • Clinical Medicine
  • Evidence-Based Medicine

Background:

  • Sickle cell disease (SCD) is a genetic disorder causing chronic anemia, pain crises, and increased risk of infections and organ damage.
  • Prevalence is high in sub-Saharan Africa, with significant carrier rates and affected births.

Purpose of the Study:

  • To systematically review the effects of pharmaceutical interventions for preventing sickle cell crisis and acute complications.
  • To provide an evidence-based summary for clinical decision-making in SCD management.

Main Methods:

  • A systematic overview was conducted, searching major medical databases up to January 2015.
  • Included studies were systematically screened, appraised, and synthesized, with a GRADE evaluation for 12 PICO combinations.

Main Results:

  • The overview identified and evaluated systematic reviews and randomized controlled trials (RCTs).
  • Efficacy was categorized for five key interventions based on effectiveness and safety data.

Conclusions:

  • The study categorized the efficacy of antibiotic prophylaxis (in two age groups), hydroxyurea, malaria chemoprophylaxis, and pneumococcal vaccines.
  • This provides a categorized efficacy assessment for crucial SCD preventive interventions.
