Platelet formation in Mediterranean macrothrombocytosis
Nouvelle Revue Francaise D'Hematologie
|June 10, 1978
Summary
Mediterranean macrothrombocytosis maintains normal platelet counts by producing fewer, larger platelets. This study reveals insights into platelet production and kinetics, highlighting the importance of platelet size and survival data.
Area of Science:
- Hematology
- Platelet Physiology
Background:
- Platelet size and survival are key parameters in hemostasis.
- Mediterranean macrothrombocytosis is a condition characterized by enlarged platelets.
Purpose of the Study:
- To investigate platelet size distribution and survival in Mediterranean macrothrombocytosis.
- To understand the mechanisms regulating platelet production and kinetics in this condition.
Main Methods:
- Comparative analysis of platelet size distribution and survival parameters.
- Study included control subjects and patients with Mediterranean macrothrombocytosis.
Main Results:
- Mediterranean macrothrombocytosis patients maintain normal platelet mass (thrombocytocrit).
- This is achieved through normal platelet survival, increased splenic pooling, and production of fewer, larger platelets.
Conclusions:
- The study provides insights into megakaryocytic mechanisms determining platelet size.
- Integrating platelet size distribution and survival parameters is crucial for understanding human platelet kinetics.

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

01:18Structure and Function of Platelets
3.6K
The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

01:31Formation of Species
45.3K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride.

Enthalpy changes are typically tabulated for reactions in which both the reactants and products are at the same conditions. A standard state is a commonly accepted set of conditions used as a reference point for the determination of properties under other different conditions. For chemists, the IUPAC standard state refers to materials under a pressure of 1 bar and solutions at 1 M and does not specify a temperature. Many thermochemical tables list values with a standard state of 1 atm. Because...

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...
