In microbiology, in vivo is often used to refer to experimentation done in a whole organism, rather than in live isolated cells, for example, cultured cells derived from biopsies. In this situation, the more specific term is ex vivo. Once cells are disrupted and individual parts are tested or analyzed, this is known as in vitro. [citation needed]
Flooding, sometimes referred to as in vivo exposure therapy, is a form of behavior therapy and desensitization —or exposure therapy —based on the principles of respondent conditioning. As a psychotherapeutic technique, it is used to treat phobia and anxiety disorders including post-traumatic stress disorder. It works by exposing the patient ...
Prolonged exposure therapy (PE) - a form of behavior therapy and cognitive behavioral therapy designed to treat post-traumatic stress disorder, characterized by two main treatment procedures – imaginal and in vivo exposures. Imaginal exposure is a repeated 'on-purpose' retelling of the trauma memory.
Definition. In vitro ( Latin for "in glass"; often not italicized in English usage [ 3][ 4][ 5]) studies are conducted using components of an organism that have been isolated from their usual biological surroundings, such as microorganisms, cells, or biological molecules. For example, microorganisms or cells can be studied in artificial culture ...
Prolonged exposure therapy. Prolonged exposure therapy ( PE) is a form of behavior therapy and cognitive behavioral therapy designed to treat post-traumatic stress disorder. It is characterized by two main treatment procedures – imaginal and in vivo exposures. Imaginal exposure is repeated 'on-purpose' retelling of the trauma memory.
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in ...
To compensate for this problem, in vivo experimentation allowed testing to occur in the original organism or environment. To bridge the dichotomy of benefits associated with both methodologies, in situ experimentation allowed the controlled aspects of in vitro to become coalesced with the natural environmental compositions of in vivo ...
DNA synthesis is the natural or artificial creation of deoxyribonucleic acid (DNA) molecules. DNA is a macromolecule made up of nucleotide units, which are linked by covalent bonds and hydrogen bonds, in a repeating structure. DNA synthesis occurs when these nucleotide units are joined to form DNA; this can occur artificially ( in vitro) or ...
