Neurobiology 
Neuropeptide Y (NPY) is a 36 amino acid peptide neurotransmitter found in the brain and autonomic nervous system. NPY has been associated with a number of physiologic processes in the brain, including the regulation of energy balance, memory and learning, and epilepsy.The main effect is increased food intake and decreased physical activity. NPY is secreted by the hypothalamus, and in addition to increasing food intake, it increases the proportion of energy stored as fat and blocks nociceptive signals to the brain NPY also augments the vasoconstrictor effects of noradrenergic neurons.

Product overview

    Carcinoembryonic antigen (carcinoembryonic antigen, CEA) is a kind of protein complex, rich in polysaccharides initially extracted from colon cancer tissue. Early fetus digestive tube and some organizations has the ability to synthesize the CEA, progesterone content gradually reduced after six months, very low levels in the blood after birth. Was later found in addition to the colon cancer, other malignant tumor patients serum CEA levels are unusually high.CEA as tumor markers in monitoring the tumor recurrence (such as colon cancer) tests can be found more early than others.
