The Cross Product Between Two Vectors Definition Let u = ai + bj + ck and v = di + ej + fk be vectors then we define the cross product v x w by the determinant of the matrix:
Huperzia serrata is a rare Chinese herb which contains a powerful alkaloid called Huperzine A (Hup A for short). According to studies, Hup A has been proven to be beneficial in protecting the brain, including slowing the progression of Alzheimer's disease.
Alpha-fetoprotein (AFP, Î±-fetoprotein; also sometimes called alpha-1-fetoprotein, alpha-fetoglobulin, or alpha fetal protein) is a protein[5][6] that in humans is encoded by the AFP gene.[7][8] The AFP gene is located on the q arm of chromosome 4 (4q25). AFP is a major plasma protein produced by the yolk sac and the liver during fetal development. It is thought to be the fetal form of serum albumin. AFP binds to copper, nickel, fatty acids and bilirubin and is found in monomeric, dimeric and trimeric forms.
