Ancitabine
|
D003504 |
[Congener of CYTARABINE that is metabolized to cytarabine and thereby maintains a more constant antineoplastic action.

|
Ancrod
|
D000721 |
[An enzyme fraction from the venom of the Malayan pit viper, Agkistrodon rhodostoma. It catalyzes the hydrolysis of a number of amino acid esters and a limited proteolysis of fibrinogen. It is used clinically to produce controlled defibrination in patients requiring anticoagulant therapy. EC 3.4.21.-.

Ancylostoma
|
D000722 |
[A genus of nematode intestinal parasites that consists of several species. A. duodenale is the common hookworm in humans. A. braziliense, A. ceylonicum, and A. caninum occur primarily in cats and dogs, but all have been known to occur in humans.

|
Ancylostomatoidea
|
D000723 |
[A superfamily of nematode parasitic hookworms consisting of four genera: ANCYLOSTOMA; NECATOR; Bunostomum; and Uncinaria. ANCYLOSTOMA and NECATOR occur in humans and other mammals. Bunostomum is common in ruminants and Uncinaria in wolves, foxes, and dogs.

Ancylostomiasis
|
D000724 |
[Infection of humans or animals with hookworms of the genus ANCYLOSTOMA. Characteristics include anemia, dyspepsia, eosinophilia, and abdominal swelling.

|
Andersen Syndrome
|
D050030 |
[A form of inherited long QT syndrome (or LQT7) that is characterized by a triad of potassium-sensitive periodic paralysis, VENTRICULAR ECTOPIC BEATS, and abnormal features such as short stature, low-set ears, and SCOLIOSIS. It results from mutations of KCNJ2 gene which encodes a channel protein (INWARD RECTIFIER POTASSIUM CHANNELS) that regulates resting membrane potential.

Andorra
|
D000725 |
[A principality in the Pyrenees between France and Spain. Its capital is also called Andorra. (From Webster's New Geographical Dictionary, 1988, p50)

Androgen Antagonists
|
D000726 |
[Compounds which inhibit or antagonize the biosynthesis or actions of androgens.
] |
|
Androgen Receptor Antagonists
|
D059002 |
[Compounds that bind to and inhibit the activation of ANDROGEN RECEPTORS.
] |
|
Androgen-Binding Protein
|
D000727 |
[Carrier proteins produced in the Sertoli cells of the testis, secreted into the seminiferous tubules, and transported via the efferent ducts to the epididymis. They participate in the transport of androgens. Androgen-binding protein has the same amino acid sequence as SEX HORMONE-BINDING GLOBULIN. They differ by their sites of synthesis and post-translational oligosaccharide modifications.

|
Androgen-Insensitivity Syndrome
|
D013734 |
[A disorder of sexual development transmitted as an X-linked recessive trait. These patients have a karyotype of 46,XY with end-organ resistance to androgen due to mutations in the androgen receptor (RECEPTORS, ANDROGEN) gene. Severity of the defect in receptor quantity or quality correlates with their phenotypes. In these genetic males, the phenotypic spectrum ranges from those with normal female external genitalia, through those with genital ambiguity as in Reifenstein Syndrome, to that of a normal male with INFERTILITY.
, A disorder also known as complete androgen insensitivity syndrome (CAIS). The 46,XY genetic male totally lacks androgen responsiveness in the target organs thus exhibits a female phenotype.
, A disorder also known as partial androgen insensitivity syndrome (PAIS). These patients exhibit partial resistance to androgenic and metabolic effects of TESTOSTERONE.

|
Androgens
|
D000728 |
[Compounds that interact with ANDROGEN RECEPTORS in target tissues to bring about the effects similar to those of TESTOSTERONE. Depending on the target tissues, androgenic effects can be on SEX DIFFERENTIATION; male reproductive organs, SPERMATOGENESIS; secondary male SEX CHARACTERISTICS; LIBIDO; development of muscle mass, strength, and power.

|
Andrographis
|
D035685 |
[A plant genus of the family ACANTHACEAE. Members contain andrographolide and other DITERPENES and androechin, a CHALCONE.
] |
|
Andrology
|
D033441 |
[A scientific or medical discipline concerning the study of male reproductive biology, diseases of the male genital organs, and male infertility. Major areas of interest include ENDOCRINOLOGY; SPERMATOGENESIS; SEMEN ANALYSIS; FERTILIZATION; CONTRACEPTION; and CRYOPRESERVATION.
] |
|
Andropause
|
D047649 |
[An endocrine state in men, characterized by a significant decline in the production of TESTOSTERONE; DEHYDROEPIANDROSTERONE; and other hormones such as HUMAN GROWTH HORMONE. Andropause symptoms are related to the lack of androgens including DEPRESSION, sexual dysfunction, and OSTEOPOROSIS. Andropause may also result from hormonal ablation therapy for malignant diseases.

|
Andropogon
|
D031722 |
[A plant genus of the family POACEAE. The common name of bluestem is also used for other plants in this family. Andropogon nardus has been reclassified as CYMBOPOGON nardus and Andropogon zizanioides as Chrysopogon zizanioides.

] |
|
Androstane-3,17-diol
|
D015113 |
[The unspecified form of the steroid, normally a major metabolite of TESTOSTERONE with androgenic activity. It has been implicated as a regulator of gonadotropin secretion.
