Alpha-Fetoprotein
Alpha-fetoprotein (609 aa, ~69 kDa) is encoded by the human AFP gene. This protein plays a role in the binding to copper, nickel, bilirubin and fatty acids in the fetal circulation.

Indicadores
The orally bioavailable alpha form of the naturally-occurring fat-soluble vitamin E, with potent antioxidant and cytoprotective activities. Upon administration, alpha-tocopherol neutralizes free radicals, thereby protecting tissues and organs from oxidative damage. Alpha-tocopherol gets incorporated into biological membranes, prevents protein oxidation and inhibits lipid peroxidation, thereby maintaining cell membrane integrity and protecting the cell against damage. In addition, alpha-tocopherol inhibits the activity of protein kinase C (PKC) and PKC-mediated pathways. Alpha-tocopherol also modulates the expression of various genes, plays a key role in neurological function, inhibits platelet aggregation and enhances vasodilation. Compared with other forms of tocopherol, alpha-tocopherol is the most biologically active form and is the form that is preferentially absorbed and retained in the body.
Glossary Term
Alternate Splicing is a process in which multiple protein isoforms or products are generated from a single gene as a result of splicing together different nonconsecutive exons during the processing of initially identical nascent transcripts of a gene into mature mRNA transcripts. An exon may be connected to any one of several alternative exons to form the mRNA and generate related proteins, often in a tissue or developmental stage specific manner.
Indicadores
A broad-spectrum semi-synthetic aminoglycoside antibiotic, derived from kanamycin with antimicrobial property. Amikacin irreversibly binds to the bacterial 30S ribosomal subunit, specifically locking 16S rRNA and S12 protein within the 30S subunit. This leads to interference with translational initiation complex and misreading of mRNA, thereby hampering protein synthesis and resulting in bactericidal effect. This agent is usually used in short-term treatment of serious infections due to susceptible strains of Gram-negative bacteria.
Pruebas
An ammonia levels test measures the amount of ammonia in a sample of your blood. Ammonia is also called NH3. It is a normal waste product in your body. Healthy bacteria in your intestines make ammonia when you digest protein in the foods you eat.
Pruebas
An amylase test measures the amount of amylase in your blood or urine (pee). Amylase is an enzyme, a protein that speeds up chemical reactions in your body. Amylase helps you digest carbohydrates . Most of the amylase in your body is made by your pancreas and salivary (spit) glands.
Pruebas
The determination of the amount of the amyloid alpha precursor protein in a biological specimen.
Pruebas
The determination of the amount of amyloid beta protein which is composed of peptides 1 to 41 in a sample.
Pruebas
An ANA test is a blood test that looks for antinuclear antibodies in your blood. Antibodies are proteins that your immune system makes to fight foreign substances, like viruses and bacteria. But an antinuclear antibody attacks your healthy cells instead. It's called "antinuclear" because it targets the nucleus of the cells, which is in charge of sending signals that are needed for important cell functions.

The determination of the amount of a complex comprised of angiopoietin-related proteins 3 and 8 in a sample.

Human ANPEP wild-type allele is located within 15q25-q26 and is approximately 30 kb in length. This allele, which encodes aminopeptidase N protein, is involved in the modulation of peptide hydrolysis and human infection by cytomegalovirus and coronavirus.
