Dicamba is toxic to conifer species but is in general less toxic to grasses. [2] Dicamba is a synthetic auxin that functions by increasing plant growth rate, leading to senescence and cell death. [2] [11] The growth regulating properties of dicamba were first discovered by Zimmerman and Hitchcock in 1942. [12]
Maternal Blood Volume. During pregnancy the plasma volume increases by 40-50% and the red blood cell volume increases only by 20–30%. [22] These changes occur mostly in the second trimester and prior to 32 weeks gestation. [24] Due to dilution, the net result is a decrease in hematocrit or hemoglobin, which are measures of red blood cell ...
Anemia is a condition in which blood has a lower-than-normal amount of red blood cells or hemoglobin. [1] Anemia in pregnancy is a decrease in the total red blood cells (RBCs) or hemoglobin in the blood during pregnancy. Anemia is an extremely common condition in pregnancy world-wide, conferring a number of health risks to mother and child. [2]
Venous stasis may occur at the end of the first trimester, due to enhanced compliance of the vessel walls by a hormonal effect. [2] Also, pregnancy can cause hypercoagulability by other factors, e.g. the prolonged bed rest that often occurs post partum that occurs in case of delivery by forceps, vacuum extractor or Caesarean section. [2] [4]
While an early study suggested that maternal red blood cells switch on hemoglobin F production during pregnancy, [27] more recent literature suggested that the increase in haemoglobin F could be, at least in part, due to fetal red blood cells being transferred to the maternal circulation. [28] [21]

It is estimated that less than 1ml of fetal blood is lost to the maternal circulation during normal labour in around 96% of normal deliveries. [1] [2] The loss of this small amount of blood may however be a sensitising event and stimulate antibody production to the foetal red blood cells, an example of which is Rhesus disease of the newborn.
2. Excessive Stress. Stress is a natural, normal part of the human experience, and your body knows how to handle it. When you’re under stress, your body releases stress hormones that activate ...
