Adeno: From 1 Different Sources
A pre?x denoting relation to a GLAND or glands.
Malignant tumour of glandular epithelium.... adenocarcinoma
See NOSE, DISORDERS OF.... adenoids
Benign tumour of glandular epithelium.... adenoma
A condition in which multiple glandular over-growths occur.... adenomatosis
A non-malignant tumour arising from the EPITHELIUM and made up of ADIPOSE TISSUE and glandular tissues (see GLAND).... adenolipoma
A compound comprising the chemical substances adenine, ribose and phosphates. The chemical bonds of the phosphates contain energy needed for cell METABOLISM that occurs when muscle cells contract. This energy is made available when ATP breaks up to form other chemical groupings – adenosine diphosphate (ADP) and adenosine monophosphate (AMP). The energy needed for recombining AMP and ADP to form ATP is produced by the breakdown of carbohydrates or other constituencies of food.... adenosine triphosphate (atp)
Viruses (see VIRUS) containing double-stranded DNA; these cause around 5 per cent of clinically recognised respiratory illnesses. Of the 40 or so known types, only a few have been properly studied to establish how they produce disease. Adenoviruses cause fever and in?ammation of the respiratory tract and mucous membranes of the eyes – symptoms resembling those of the common cold. They also cause ENTERITIS, haemorrhagic CYSTITIS and life-threatening infections in newborn babies. Infections are generally benign and self-limiting, and treatment is symptomatic and supportive, although the elderly and people with chronic chest conditions may develop secondary infections which require antibiotic treatment.... adenoviruses
n. the anterior lobe of the *pituitary gland.... adenohypophysis
n. see Warthin’s tumour.... adenolymphoma
a condition in which angiofibromas (flesh-coloured or pink papules) are often seen around the nose and cheek or elsewhere on the face. They are a cutaneous sign of *tuberous sclerosis.... adenoma sebaceum
n. see endometriosis.... adenomyosis
n. a *nucleoside that contains adenine and the sugar ribose and occurs in *ATP. It is also used as an *anti-arrhythmic drug to stop *supraventricular tachycardias and restore a normal heart rhythm. As such, it needs to be injected or infused quickly, which may fleetingly make the patient feel faint and develop chest pain.... adenosine
(ADA deficiency) a genetic disorder affecting about one baby in 25,000 and characterized by a defect in adenosine deaminase (ADA), an enzyme that is involved in purine metabolism. Deficiency of this enzyme results in selective damage to the antibody-producing lymphocytes; this in turn leads to a condition known as *severe combined immune deficiency (SCID), in which the affected baby has no resistance to infection and must be entirely isolated from birth. Such children have only about a 50% chance of surviving for six months. See also gene therapy.... adenosine deaminase deficiency
see ADP.... adenosine diphosphate
see AMP.... adenosine monophosphate
see ATP.... adenosine triphosphate
n. (pl. adenoses) 1. excessive growth or development of glands. 2. any disease of a gland or glandlike structure, especially of a lymph node.... adenosis
n. one of a group of DNA-containing viruses causing infections of the upper respiratory tract that produce symptoms resembling those of the common cold.... adenovirus
(FAP) see polyposis.... familial adenomatous polyposis
a type of polyp that arises in the colon and rectum and can undergo malignant transformation, usually over a period of years, although this can occur more rapidly in familial *polyposis syndromes.... tubulovillous adenoma
the presence of glandular tissue in or under the vaginal epithelium that undergoes squamous *metaplasia. It may be associated with intrauterine *diethylstilbestrol exposure. See also clear-cell carcinoma.... vaginal adenosis
