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 ...
All values in Hematology – red blood cells (except hemoglobin in plasma) All values in Hematology – white blood cells; Platelet count (Plt) A few values are for inside red blood cells only: Vitamin B 9 (folic acid/folate) in red blood cells; Mean corpuscular hemoglobin concentration (MCHC)
To do this their hemoglobin levels should not be allowed to drop below 90 to 105 g/L (9 to 10.5 g/dL). [ 27 ] There is insufficient evidence to recommend a particular hemoglobin threshold in people with myelodysplasia or aplastic anemia , [ 28 ] and guidelines recommend an individualized approach to transfusion.

[4] Central to the physiologic maintenance of GFR is the differential basal tone of the afferent (input) and efferent (output) arterioles (see diagram).
It affects women more than men due to the sharp fall in estrogen production that follows menopause. [193] Globally, it is estimated that 21.2% of women and 6.3% of men over the age of 50 have osteoporosis, corresponding to a total of around 500 million people worldwide. [194] About 15% of Caucasians in their 50s and 70% of those over 80 are ...
Women's health differs from that of men's health in many unique ways. Women's health is an example of population health, where health is defined by the World Health Organization (WHO) as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity".

Klinefelter syndrome can also result from an extra X chromosome in only some of the body's cells. These cases are called mosaic 46,XY/47,XXY. Trisomy X. This syndrome results from an extra copy of the X chromosome in each of a female's cells. Females with trisomy X have three X chromosomes, for a total of 47 chromosomes per cell.
