Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen ...
Phosphatidylserine (abbreviated Ptd-L-Ser or PS) is a phospholipid and is a component of the cell membrane. [ 1] It plays a key role in cell cycle signaling, specifically in relation to apoptosis. It is a key pathway for viruses to enter cells via apoptotic mimicry. [ 2] Its exposure on the outer surface of a membrane marks the cell for ...
Meso-Zeaxanthin ( 3R,3′S-Zeaxanthin) is a xanthophyll carotenoid, and is one of the three stereoisomers of zeaxanthin. The meso form is the second most abundant in nature, after 3R,3′R-zeaxanthin, which is produced by plants and algae. [1] meso -Zeaxanthin has been identified in specific tissues of marine organisms [2] and in the macula ...
While it’s certainly sobering that cardiovascular disease is the number one cause of death in this country, the good news is that this is a health condition that’s largely avoidable.
54,200 (2015) [ 7] Iron-deficiency anemia is anemia caused by a lack of iron. [ 3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [ 3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [ 1]
Venous oxygen saturation (SvO 2) is the percentage of oxygenated hemoglobin returning to the right side of the heart. It can be measured to see if oxygen delivery meets the tissues' demands. SvO 2 typically varies between 60% and 80%. [ 9] A lower value indicates that the body is in lack of oxygen, and ischemic diseases occur.
Human iron metabolism is the set of chemical reactions that maintain human homeostasis of iron at the systemic and cellular level. Iron is both necessary to the body and potentially toxic. Controlling iron levels in the body is a critically important part of many aspects of human health and disease.
Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen ( O. 2) at increased partial pressures. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes. Historically, the central nervous system condition was called the Paul Bert effect ...
