Thus, 1 g/dL=0.1551 mmol/L. Hemoglobin A is the most intensively studied of the hemoglobin molecules. [citation needed] In human infants, the fetal hemoglobin molecule is made up of 2 α chains and 2 γ chains. The γ chains are gradually replaced by β chains as the infant grows. [53]
Estradiol is responsible for the development of female secondary sexual characteristics such as the breasts, widening of the hips and a female pattern of fat distribution. It is also important in the development and maintenance of female reproductive tissues such as the mammary glands , uterus and vagina during puberty , adulthood and pregnancy ...
The Mentzer index, described in 1973 by William C. Mentzer, [1] is the MCV divided by the RBC count. It is said to be helpful in differentiating iron deficiency anemia from beta thalassemia trait. [2] [3] The index is calculated from the results of a complete blood count.
Some evidence supports holding off on blood transfusions in those who have a hemoglobin greater than 7 to 8 g/dL and only moderate bleeding. [15] [22] If the INR is greater than 1.5 to 1.8 correction with fresh frozen plasma, prothrombin complex may decrease mortality. [15]
Pattern hair loss (also known as androgenetic alopecia (AGA) [1]) is a hair loss condition that primarily affects the top and front of the scalp. [2] [3] In male-pattern hair loss (MPHL), the hair loss typically presents itself as either a receding front hairline, loss of hair on the crown and vertex of the scalp, or a combination of both.
Typically, the cells of female humans contain two X chromosomes, while the cells of male humans have an X and a Y chromosome. [23] During early fetal development , all embryos have phenotypically female genitalia up until week 6 or 7, when a male embryo's gonads differentiate into testes due to the action of the SRY gene on the Y chromosome.

Sex category (i.e. female sex) 1 Thus, the CHA 2 DS 2 -VASc score is a refinement of CHADS 2 [ 8 ] [ 10 ] score and extends the latter by including additional common stroke risk factors, that is, age 65–74, female gender and vascular disease. [ 11 ]
In a healthy adult male of 75 kg (165 lb) with a blood volume of 5 L, a blood glucose level of 5.5 mmol/L (100 mg/dL) amounts to 5 g, equivalent to about a teaspoonful of sugar. [14] Part of the reason why this amount is so small is that, to maintain an influx of glucose into cells, enzymes modify glucose by adding phosphate or other groups to it.
