A Wisdom Archive on Platelets

Wound healing, or wound repair, is the body's natural process of regenerating dermal and epidermal tissue. When an individual is wounded, a set of events takes place in a predictable fashion to repair the damage. These events overlap in time (Midwood et al., 2004) and must be artificially categorized into separate steps: the inflammatory, proliferative, and maturation phases (Some authors consider healing to take place in four stages, by splitting different parts inflammation or proliferation into se ...

In gemology, aventurescence (sometimes called aventurization) is an optical reflectance effect seen in certain gems. The effect amounts to a metallic glitter, arising from minute, preferentially oriented mineral platelets within the material. These platelets are so numerous that they also influence the material's body colour. In aventurine quartz (actually a type of quartzite) chrome-bearing fuchsite makes for a green ... Including:

Nacre, also known as mother of pearl or sadaf, is a naturally occuring organic-inorganic composite. It is formed of layers of calcium carbonate (CaCO3) platelets (crystals), in the form of aragonite and conchiolin (a scleroprotein), separated by elastic biopolymers (such as chitin and lustrin). This mixture of hard and elastic domains makes the material strong and resilient. Strength and resilience is also likely to be due to the offset or "brickwork" arrangement of the platelets, ...

An antiplatelet drug is a member of a class of pharmaceuticals that decreases platelet aggregation and inhibits thrombus formation. They are effective in the arterial circulation, where anticoagulants have little effect. They are widely used in primary and secondary prevention of thrombotic cerebrovascular or cardiovascular disease. The most important antiplatelet drugs are : cyclooxygenase inhibitors aspirin adenosine diphosphate receptor inhibitors clopidogrel (P ...

C6H4(OCOCH3)COOH Aspirin or acetylsalicylic acid is a drug in the family of salicylates, often used as an analgesic (against minor pains and aches), antipyretic (against fever), and anti-inflammatory. It has also an anticoagulant (blood thinning) effect and is used in long-term low-doses to prevent heart attacks. Low-dose long-term aspirin irreversibly blocks formation of thromboxane A2 in platelets, producing an inhibitory effect on platelet aggregation, and this blood thi ... Including:

A thrombus or blood clot is the final product of blood coagulation, through the aggregation of platelets and the activation of the humoral coagulation system. Thrombus is physiologic in cases of injury, but pathologic in case of thrombosis. Some of the conditions in which blood clots develop include atrial fibrillation (a form of cardiac arrhythmia), heart valve replacement, a recent heart attack, extended periods of inactivity (see deep venous thrombosis), and genetic or disease related deficiencies in the blood's clott ...

Uremia is a toxic condition resulting from renal failure, when kidney function is compromised and urea, a waste product normally excreted in the urine, is retained in the blood. Uremia can lead to disturbances in the platelets, among other effects. Azotemia is another word that refers to high levels of urea, but is used primarily when the abnormality can be measured chemically but is not yet so severe as to produce symptoms. Uremia takes a long time to develop. Other related archivesAz
