B-lymphocyte antigen CD20 or CD20 is B lymphocyte cell-surface molecule. It is a 33-37 kDa non-glycosylated protein. CD20 is expressed on the surface of B-cells from the pre-B phase, the expression is lost in terminally differentiated plasma cells. [5] [6] CD20 is used as a therapeutical target of B-cell malignancies and autoimmune diseases. [6]
Breast size does not determine the amount of milk a woman will produce or whether she will be able to successfully breastfeed her baby. [21] Larger breast size pre pregnancy is a sign there are more fatty cells within the breast, which do not affect milk production. A more important indicator is breast changes during the course of pregnancy.
Prolactin has a wide variety of effects. It stimulates the mammary glands to produce milk (): increased serum concentrations of prolactin during pregnancy cause enlargement of the mammary glands and prepare for milk production, which normally starts when levels of progesterone fall by the end of pregnancy and a suckling stimulus is present.

The term is used only after a mother's milk "comes in", which usually occurs around 30–40 hours after delivery of a full-term infant. Low milk supply is distinct from the scenario in which the mother's milk comes in later than normal but is thereafter produced in sufficient quantities; this is known as delayed onset of lactation (delayed ...

About 30% of all preterm deliveries (before 37 weeks) are complicated by PPROM, and rupture of membranes before viability (before 24 weeks) occurs in less than 1% of all pregnancies. [11] Since there are significantly fewer preterm deliveries than term deliveries, the number of PPROM cases make up only about 5% of all cases of PROM.
A baby's chances for survival increases 3 to 4 percentage points per day between 23 and 24 weeks of gestation, and about 2 to 3 percentage points per day between 24 and 26 weeks of gestation. After 26 weeks the rate of survival increases at a much slower rate because survival is high already. [ 16 ]
