Immortalised cell lineAn immortalised cell line is a population of cells from a multicellular organism which would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular senescence and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro. The mutations required for immortality can occur naturally or be intentionally induced for experimental purposes. Immortal cell lines are a very important tool for research into the biochemistry and cell biology of multicellular organisms.
Système d'atterrissage aux instrumentsLe système d'atterrissage aux instruments ou ILS (acronyme de l'anglais instrument landing system) est un moyen de radio-navigation utilisé pour l'approche de précision d'aéronefs en régime de vol aux instruments. La procédure correspondante est appelée approche ILS. thumb|Indicateur : (de gauche à droite) trop à droite, bien centré, trop à gauche Il comprend deux éléments : un localizer (LOC) qui fournit l'écart de l'avion par rapport à l'axe de la piste ; un glide path qui fournit l'écart de l'avion par rapport à la pente nominale d'approche (le plus souvent 3 degrés).
Anorectal manometryAnorectal manometry (ARM) is a medical test used to measure pressures in the anus and rectum and to assess their function. The test is performed by inserting a catheter, that contains a probe embedded with pressure sensors, through the anus and into the rectum. Patients may be asked to perform certain maneuvers, such as coughing or attempting to defecate, to assess for pressure changes. Anorectal manometry is a safe and low risk procedure.
PubChemPubChem est une banque de données américaine de molécules chimiques gérée par le National Center for Biotechnology Information (NCBI), branche de la Bibliothèque nationale de médecine des États-Unis sous l'autorité des National Institutes of Health (NIH). PubChem répertorie plusieurs millions de composés en mettant gratuitement en ligne, pour chaque substance, une grande quantité de données de divers ordres : chimique, biochimique, pharmacologique, production, toxicologique, environnemental Des accès aux données de PubChem sont possibles par des langages de script tels que Python, Ruby ou Perl.
Incontinence fécaleFecal incontinence (FI), or in some forms encopresis, is a lack of control over defecation, leading to involuntary loss of bowel contents, both liquid stool elements and mucus, or solid feces. When this loss includes flatus (gas), it is referred to as anal incontinence. FI is a sign or a symptom, not a diagnosis. Incontinence can result from different causes and might occur with either constipation or diarrhea. Continence is maintained by several interrelated factors, including the anal sampling mechanism, and incontinence usually results from a deficiency of multiple mechanisms.
Progestogen (medication)A progestogen, also referred to as a progestagen, gestagen, or gestogen, is a type of medication which produces effects similar to those of the natural female sex hormone progesterone in the body. A progestin is a synthetic progestogen. Progestogens are used most commonly in hormonal birth control and menopausal hormone therapy. They can also be used in the treatment of gynecological conditions, to support fertility and pregnancy, to lower sex hormone levels for various purposes, and for other indications.
Culture industryThe term culture industry (Kulturindustrie) was coined by the critical theorists Theodor Adorno (1903–1969) and Max Horkheimer (1895–1973), and was presented as critical vocabulary in the chapter "The Culture Industry: Enlightenment as Mass Deception", of the book Dialectic of Enlightenment (1947), wherein they proposed that popular culture is akin to a factory producing standardized cultural goods—films, radio programmes, magazines, etc.—that are used to manipulate mass society into passivity.
Lever arm shock absorberLever arm shock absorbers were the first form of hydraulic shock absorber or damper used for car suspension. They appeared in the 1930s and were most commonly used in the 1950s and 1960s, but were replaced by telescopic shock absorbers in the 1970s. One of the earliest patents for a hydraulic lever arm shock absorber was awarded in 1925 to Georges de Ram, who was already an established maker of friction disk shock absorbers. Hydraulic shock absorbers, invented by Ralph Peo in 1930, appeared as a development to replace the previous friction disks.
