Transfer factor factors are contraindicated for women who are pregnant or breastfeeding. When human- and bovine-derived transfer factor are generated from blood cells they carry the potential for blood-borne disease such as HIV/AIDS and Hepatitis C. Colostrum is a form of milk produced by the mammary glands of mammals (including humans) in late pregnancy. Colostrum also contains multiple immune modulating molecules, including high antibody levels. Based on studies noting an overlap in the observed in vitro effects between a molecule contained in colostrum called colostrinin and the dialyzable leukocyte extract mentioned above, a hypothesis formed that the two were the same. There
Conjunctive normal form formula_30 and formula_31 with a new variable, and repeating as often as necessary. To convert first-order logic to CNF: As an example, the formula saying ""Anyone who loves all animals, is in turn loved by someone"" is converted into CNF (and subsequently into clause form in the last line) as follows (highlighting replacement rule redices in formula_71): Informally, the skolem function formula_72 can be thought of as yielding the person by whom formula_60 is loved, while formula_74 yields the animal (if any) that formula_60 doesn't love. The 3rd last line from below then reads as ""formula_60 doesn't love the animal
