Glossary Term
Pertaining to a portion of the whole; any one of two or more samples of something, of the same volume or weight.
Glossary Term
Mutually exclusive alternative forms of the same gene occupying the same locus on homologous chromosomes, differing in nucleotide sequence and governing the same biochemical and developmental process.
Pruebas
The determination of the amount of alpha globulin present in a sample.

The determination of the amount of alpha-1 acid glycoprotein present in a sample.
Pruebas
The determination of the amount of alpha-fetoprotein present in a blood sample.
Pruebas
The determination of the amount of the alpha-methylfentanyl in a sample.
Pruebas
The determination of the amount of alpha-N-acetylglucosaminidase present in a sample.
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
The determination of the amount of amphiregulin in a sample.
Glossary Term
A statistical technique which helps in making inference whether three or more samples might come from populations having the same mean; specifically, whether the differences among the samples might be caused by chance variation.
