Biofilm: An aggregate of
microbes with a distinct architecture. A biofilm is like a tiny city in which
microbial cells, each only a micrometer or two long, form towers that can be
hundreds of micrometers high. The "streets" between the towers are really
fluid-filled channels that bring in nutrie...
Biofluid: A biological fluid. Biofluids can be excreted (such as urine or sweat), secreted (such as breast milk or bile), obtained with a needle (such as blood or cerebrospinal fluid), or develop as a result of a pathological process (such as (such as blister or cyst fluid). The term biofluid is emp...
Bioidentical hormone therapy
therapy: Treatment with hormone medications
that contain hormones that have the same chemical formula as those made
naturally in the body, referred to by many as "bioidentical" hormones.
Bioidentical hormones are created in a laboratory by altering compounds derived
Bioinformatics: The sum of the computational approaches to analyze, manage, and store biological data. Bioinformatics involves the analysis of biological information using computers and statistical techniques, the science of developing and utilizing computer databases and algorithms to accelerate an...
Biologic evolution: Biologic evolution was contrasted
with cultural (social) evolution in 1968 by A.G. Motulsky who pointed
out that biologic evolution is mediated by genes, shows a slow rate
of change, employs random variation (mutations) and selection as
agents of change, new variants are often...
Biological chemistry: Another name for biochemistry -- the study of the chemistry of living cells, tissues, organs and organisms. One of the premier journals of biochemistry today is the JBC, the Journal of Biological Chemistry, which was founded in 1905. ...
Biological response modifiers
Biological response modifiers (BRMs): Substances
that stimulate the body's response to infection and disease. The body
naturally produces small amounts of these substances. Scientists can
produce some of them in the laboratory in large amounts for use in
treating cancer, rheumatoid arthritis, an...
