Bioelectric impedance analysis: A seemingly simple method for determining the lean body mass. Abbreviated BIA. There are two methods of the BIA. One involves standing on a special scale with footpads. A harmless amount of electrical current is sent through the body, and then the percentage of body fat is calculated. The other type of BIA involves electrodes usually placed on a wrist and an ankle and on the back of the right hand and on the top of the foot. The change in voltage between electrodes is measured. The person’s body fat percentage is then calculated from the results of the BIA.
Biofeedback: A method of treatment that uses a monitor to measure patients’ physiologic information of which they are normally unaware. By watching a monitor, patients can learn by trial and error to adjust their thinking and other mental processes in order to control ‘involuntary’ bodily processes such as blood pressure, temperature, gastrointestinal functioning, and brain […]
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 nutrients, oxygen and other necessities for live […]
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 employed as both a […]
- Bioidentical hormone therapy
Bioidentical hormone 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 from naturally-occurring plant products and are typically taken in the form of creams or […]
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 and enhance biological research. Bioinformatics is used in analyzing genomes, proteomes (protein sequences), three-dimensional modeling of biomolecules […]
