2. Heart valve - Wikipedia

   en.wikipedia.org/wiki/Heart_valve

   A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine the direction of blood flow through the heart. Heart valves are opened or closed by a difference in blood pressure on each side. [1] [2] [3]

3. GC skew - Wikipedia

   en.wikipedia.org/wiki/GC_skew

   This asymmetry is due to the formation of the replication fork and its division into nascent leading and lagging strands. The leading strand is synthesized continuously and in juxtapose to the leading strand; the lagging strand is replicated through short fragments of polynucleotide (Okazaki fragments) in a 5' to 3' direction. [6]

4. Artificial heart valve - Wikipedia

   en.wikipedia.org/wiki/Artificial_heart_valve

   Blood clots can be hazardous because they can lodge in, and block, downstream arteries (e.g. coronary arteries, leading to heart attack [myocardial infarction]; or cerebral arteries, leading to stroke). A desirable characteristic of artificial heart valves is that they are non- or minimally thrombogenic.

5. Cardiology diagnostic tests and procedures - Wikipedia

   en.wikipedia.org/wiki/Cardiology_diagnostic...

   A variety of blood tests are available for analyzing cholesterol transport behavior, HDL, LDL, triglycerides, lipoprotein little a, homocysteine, C-reactive protein, blood sugar control: fasting, after eating or averages using glycated albumen or hemoglobin, myoglobin, creatine kinase, troponin, brain-type natriuretic peptide, etc. to assess the evolution of coronary artery disease and ...

6. Venous thrombosis - Wikipedia

   en.wikipedia.org/wiki/Venous_thrombosis

   Venous thrombosis is the blockage of a vein caused by a thrombus (blood clot). A common form of venous thrombosis is deep vein thrombosis (DVT), when a blood clot forms in the deep veins. If a thrombus breaks off and flows to the lungs to lodge there, it becomes a pulmonary embolism (PE), a blood clot in the

7. Coronary thrombosis - Wikipedia

   en.wikipedia.org/wiki/Coronary_thrombosis

   This blood clot may then restrict blood flow within the heart, leading to heart tissue damage, or a myocardial infarction, also known as a heart attack. [ 1 ] Coronary thrombosis is most commonly caused as a downstream effect of atherosclerosis , a buildup of cholesterol and fats in the artery walls.

8. Aortic valve - Wikipedia

   en.wikipedia.org/wiki/Aortic_valve

   Tissue heart valves are usually made from animal tissues, either animal heart valve tissue or animal pericardial tissue, commonly from the pig. The tissue is pretreated by removing antigens to prevent rejection and to prevent calcification. These valves tend to model after normal valves by having leaflets that form cusps and sinuses. There are ...

9. Replisome - Wikipedia

   en.wikipedia.org/wiki/Replisome

   The dimerisation of the replicative polymerases solves the problems related to efficient synchronisation of leading and lagging strand synthesis at the replication fork, but the tight spatial-structural coupling of the replicative polymerases, while solving the difficult issue of synchronisation, creates another challenge: dimerisation of the ...
