Bioelectric Energy Sources
|
D001674 |
[Electric power supply devices which convert biological energy, such as chemical energy of metabolism or mechanical energy of periodic movements, into electrical energy.
] |
|
Bioengineering
|
D057005 |
[The application of engineering principles and methods to living organisms or biological systems.
] |
|
Bioethical Issues
|
D026688 |
[Clusters of topics that fall within the domain of BIOETHICS, the field of study concerned with value questions that arise in biomedicine and health care delivery.
] |
|
Bioethics
|
D001675 |
[A branch of applied ethics that studies the value implications of practices and developments in life sciences, medicine, and health care.

|
Biofeedback, Psychology
|
D001676 |
[The therapy technique of providing the status of one's own AUTONOMIC NERVOUS SYSTEM function (e.g., skin temperature, heartbeats, brain waves) as visual or auditory feedback in order to self-control related conditions (e.g., hypertension, migraine headaches).
] |
|
Biofilms
|
D018441 |
[Encrustations formed from microbes (bacteria, algae, fungi, plankton, or protozoa) embedded in an EXTRACELLULAR POLYMERIC SUBSTANCE MATRIX that is secreted by the microbes. They occur on body surfaces such as teeth (DENTAL DEPOSITS); inanimate objects, and bodies of water. Biofilms are prevented from forming by treating surfaces with DENTIFRICES; DISINFECTANTS; ANTI-INFECTIVE AGENTS; and anti-fouling agents.

|
Biofortification
|
D000072759 |
[Improving the NUTRITIONAL VALUE of plant foods by augmenting the plant's environment, by using PLANT BREEDING, or by GENETIC ENGINEERING plants to increase their ability to synthesize VITAMINS or uptake essential NUTRIENTS from the soil.
] |
|
Biofouling
|
D057219 |
[Process by which unwanted microbial, plant or animal materials or organisms accumulate on man-made surfaces.
] |
|
Biofuels
|
D056804 |
[Hydrocarbon-rich byproducts from the non-fossilized BIOMASS that are combusted to generate energy as opposed to fossilized hydrocarbon deposits (FOSSIL FUELS).
] |
|
Biogenic Amines
|
D001679 |
[A group of naturally occurring amines derived by enzymatic decarboxylation of the natural amino acids. Many have powerful physiological effects (e.g., histamine, serotonin, epinephrine, tyramine). Those derived from aromatic amino acids, and also their synthetic analogs (e.g., amphetamine), are of use in pharmacology.
] |
|
Biogenic Monoamines
|
D015306 |
[Biogenic amines having only one amine moiety. Included in this group are all natural monoamines formed by the enzymatic decarboxylation of natural amino acids.
] |
|
Biogenic Polyamines
|
D015317 |
[Biogenic amines having more than one amine group. These are long-chain aliphatic compounds that contain multiple amino and/or imino groups. Because of the linear arrangement of positive charge on these molecules, polyamines bind electrostatically to ribosomes, DNA, and RNA.

|
Biographies as Topic
|
D001680 |
[Works about a written account of a person's life and the branch of literature concerned with the lives of people.
] |
|
Biography
|
D019215 |
[Works consisting of an account of the events, works, and achievements, personal and professional, during a person's life.
] |
|
Biohazard Release
|
D055885 |
[Uncontrolled release of biological material from its containment. This either threatens to, or does, cause exposure to a biological hazard. Such an incident may occur accidentally or deliberately.
] |
|
Biolistics
|
D019470 |
[Techniques where DNA is delivered directly into organelles at high speed using projectiles coated with nucleic acid, shot from a helium-powered gun (gene gun). One of these techniques involves immunization by DNA VACCINES, which delivers DNA-coated gold beads to the epidermis.
] |
|
Biological Assay
|
D001681 |
[A method of measuring the effects of a biologically active substance using an intermediate in vivo or in vitro tissue or cell model under controlled conditions. It includes virulence studies in animal fetuses in utero, mouse convulsion bioassay of insulin, quantitation of tumor-initiator systems in mouse skin, calculation of potentiating effects of a hormonal factor in an isolated strip of contracting stomach muscle, etc.

|
Biological Availability
|
D001682 |
[The extent to which the active ingredient of a drug dosage form becomes available at the site of drug action or in a biological medium believed to reflect accessibility to a site of action.
] |
|
Biological Clocks
|
D001683 |
[The physiological mechanisms that govern the rhythmic occurrence of certain biochemical, physiological, and behavioral phenomena.
] |
|
Biological Coevolution
|
D000073930 |
[The process of reciprocal evolutionary change occurring between pairs of species or among groups of species as they interact.
