Glossary Term
Ubiquitin is a family of widely distributed proteins found in all eukaryotes that contain a highly conserved sequence of 76 amino acids identical in organisms from humans to insects. It participates in diverse cellular functions by conjugation to other proteins through its carboxy terminus. Ubiquitination is associated with many highly regulated biological events including protein degradation, chromatin remodelling, heat shock, cell cycle progression, differentiation, antigen presentation, retrovirus assembly, apoptosis, signal transduction, transcriptional activation, biological clocks, receptor down regulation, and endocytosis. Protein ubiquitination regulates the half-lives of many proteins by targeting them for degradation. Newly discovered families of ubiquitination and deubiquitination enzymes participate in these processes. Ubiquitination enzymes may provide new therapeutic targets and ways of intervention in many human diseases.

Indicadores
A branched tricyclic glycosylated peptide with bactericidal activity against most organisms and bacteriostatic effect on enterococci. At a site different from that of penicillins and cephalosporins, vancomycin binds tightly to the D-alanyl-D-alanine portion of cell wall precursors, thereby interfering with bacterial cell wall synthesis. This leads to activation of bacterial autolysins that destroy the cell wall by lysis. Vancomycin may also alter the permeability of bacterial cytoplasmic membranes and may selectively inhibit RNA synthesis.
Indicadores
Vascular endothelial growth factor A (232 aa, ~27 kDa) is encoded by the human VEGFA gene. This protein plays a role in both cell proliferation and angiogenesis.

Indicadores
A group of water-soluble vitamins essential for metabolism and normal physiological functions. B6 vitamins, including pyridoxine, pyridoxal, and pyridoxamine, are converted in vivo to pyridoxal phosphate, a cofactor necessary for the synthesis of amino acids, neurotransmitters, and sphingolipids. More than 100 enzymes involved in protein metabolism require vitamin B6 as a cofactor. Vitamin B6 is essential to red blood cell, nervous system, and immune systems functions and helps maintain normal blood glucose levels. Vitamin B6 is found in a wide variety of foods including cereals, beans, meat, poultry, fish, and some fruits and vegetables. (NCI04)

A vitamin E test measures the amount of vitamin E in your blood. Vitamin E (also known as tocopherol or alpha-tocopherol) is a nutrient that is found in every cell of your body. It helps your nerves and muscles work well, prevents blood clots, and boosts your immune system so it can fight off infections from germs .

Pruebas
This test looks for white blood cells in a sample of your stool (poop). White blood cells are also called leukocytes, so this test is sometimes called a leukocytes in stool test.

A white blood count measures the number of white blood cells (WBCs) in your blood. White blood cells, also called leukocytes, are part of your immune system . They are a type of blood cell made in your bone marrow and found in your blood and lymph tissue (part of your immune system). If you are injured or get sick, the white blood cells will travel through your bloodstream and tissues to where they are needed. There, they will help your body fight off infections and other diseases.
