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.

Prenex normal form "all" be written in universal-existential form, a special case of the prenex normal form that has every universal quantifier preceding any existential quantifier, so that all sentences can be rewritten in the form formula_79 formula_80 formula_81 formula_82 formula_83 formula_46, where formula_46 is a sentence that does not contain any quantifier. This fact allowed Tarski to prove that Euclidean geometry is decidable. Prenex normal form A formula of the predicate calculus is in prenex normal form if it is written as a string of quantifiers and bound variables, called the prefix, followed by a quantifier-free part, called the matrix. Every formula
