The Adena Regional Medical Center is a hospital in Chillicothe, Ohio, United States.
Adenine
A purine base found in RNA and DNA; in double-stranded DNA adenine pairs with the pyrimidine thymine.
Adenine (A)
"One member of the A-T (adenine-thymine) base pair in DNA. The other base pair in DNA is G-C (guanine-cytosine). Each base pair forms a ""rung of the DNA ladder."" A DNA nucleotide is made of a molecule of sugar, a molecule of phosphoric acid, and a molecule called a base. The bases are the ""letters"" that spell out the genetic code. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In DNA base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine. Adenine is also one of the bases in RNA. There it always pairs with uracil (U). The base pairs in RNA are therefore A-U and G-C."
Adenitis
Inflammation of a gland.
Adeno-
"Prefix referring to a gland, as in adenoma and adenopathy. From the Greek aden meaning originally ""an acorn"" and later ""a gland"" in the form of an acorn. Before a vowel, adeno- becomes aden-, as in adenitis (inflammation of a gland)."
Adenocard
Adenocard is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): adenosine .
Adenoid cystic carcinoma
"A type of cancer that most often develops in the salivary glands of the head and neck. It may arise in other sites such as the skin, lacrimal gland, trachea, breast, cervix and prostate. Adenoid cystic carcinoma (ACC) has a characteristic appearance under the microscope. Abnormal ""nests"" or cords of certain cells (epithelial cells) can be seen to surround or infiltrate ducts and glandular structures. These structures are typically filled with a mucous-like material or contain abnormal fibrous membranes (hyaline membranes). ACC is an unusual tumor. It is slow-growing but relentless. It tends to be locally invasive and infiltrate the ""sheaths"" or coatings surrounding nerve fibers (perineural spaces). ACC often recurs years later at the site where the tumor first arose or it may metastasize. Unlike most carcinomas, it seldom metastasizes to nearby lymph nodes but rather to distant sites. The lung is the most common site of metastasis, with the liver second. Bone metastases indicate a poor prognosis . Treatment usually involves surgery to resect (remove) the tumor. Postoperative radiotherapy may help prevent local recurrence. Chemotherapy may slow the tumor but no chemotherapy has yet been found that is effective in destroying it."
Adenoidectomy
The surgical removal of the adenoids.
Adenoiditis
Infection of the adenoids.
Adenoids
Glandular tissue in the back of the throat that may swell, especially during childhood, obstruct breathing and speaking, and lead to ear infections.
Adenoids and Tonsils
"These celebrated structures in the back of the throat are composed of tissue similar to the lymph nodes or ""glands."" "
Adenoma
A benign epithelial tumor in which the cells form glandular structures or are derived from glandular epithelium.

Adenomyoma
A nodule that forms around tissue of the inner uterus (endometrial tissue) as a result of adenomyosis. See adenomyosis.
Adenomyomata
Plural form of adenomyoma.
Adenomyosis
Pronounced a-den-o- mi-o-sis, this is a common benign condition of the uterus in which the endometrium (the mucous membrane lining the inside of the uterus) grows into the myometrium (the uterine musculature located just outside the endometrium). The endometrium and myometrium under normal circumstances are adjacent to one another, discrete neighbors. In adenomyosis, the endometrium boorishly implants itself in the myometrium. The myometrium may respond to this intrusion with muscular overgrowth. If an island of endometrial tissue is contained and circumscribed within the myometrium, it forms a nodule called an adenomyoma (plural: adenomyomata). Adenomyosis is made up of adeno (gland) + myo (muscle) + osis (a condition of) = a condition of glandular tissue (referring to the endometrium) in the muscle (the myometrium). Adenomyosis goes by several other names including endometriosis interna, endometriosis uterina, adenomyosis uteri and adenomyometritis.
Adenomyosis uteri
Also known more succinctly as adenomyosis (pronounced ad-den-o-mi-o- sis), this is a common benign condition of the uterus in which the endometrium (the mucous membrane lining the inside of the uterus) grows into the myometrium (the uterine musculature located just outside the endometrium) The endometrium and myometrium under normal circumstances live adjacent to one another as discrete neighbors. In adenomyosis, the endometrium invades the myometrium. The myometrium may respond to this intrusion with muscular overgrowth. If an island of endometrial tissue is contained and circumscribed within the myometrium, it forms a nodule called an adenomyoma (plural: adenomyomata). Adenomyosis is made up of adeno (gland) + myo (muscle) +osis (a condition of) = a condition of glandular tissue (referring to the endometrium) in the muscle (the myometrium). Adenomyosis goes by several other names including endometriosis interna or uterina, and adenomyometritis.
Adenopathy
"Large or ""swollen"" lymph nodes. Synonymous with lymphadenopathy."
Adenoscan
Adenoscan is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): adenosine .
Adenosine
A nucleoside containing adenine as its base. Adenosine acts to dilate the coronary arteries and is employed in the adenosine thallium scan of the heart.
Adenosine deaminase (ADA)
An enzyme that plays a key role in salvaging purine molecules.
Adenosine deaminase (ADA) deficiency
A genetic (inherited) condition that results in a immune deficiency disorder called severe combined immunodeficiency disease. Adenosine deaminase is an enzyme that plays a key role in salvaging purine molecules. ADA deficiency is of special interest in the history of genetics. The first successful instance of gene therapy in humans was carried out in 1990 by Drs. W. French Anderson, R. Michael Blaese and Kenneth W. Culver who infused genetically engineered blood cells to repair ADA deficiency.
Adenosine thallium scan
A method of examining the heart to obtain information about the blood supply to the heart muscle. Special cameras take a series of pictures of the heart. Radioactive thallium is injected into the bloodstream and serves as a tracer. The tracer attaches to certain cells and makes them visible to the special camera. The tracer attaches to the muscle cells of the heart so the imaging camera can take pictures of the heart muscles. If an area of the heart does not receive an adequate flow of blood, the cells in the underserved area do not receive as much tracer and it appears as a darker area on the picture taken by the camera.
Adenosine triphosphate
The primary fuel used by cells to generate the biochemical reactions essential for life.
Adenovirus
One of the viruses that cause the common cold.
Adensoine
Adensoine is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): adenosine .

Adjuvant treatment

Adrenal glands
Two glands, one on top of each kidney, which produce a variety of hormones that affect nearly every body system.
Adrenaline
Or epinephrine. One of two chemicals (the other is norepinephrine) released by the adrenal gland that increases the speed and force of heartbeats. It dilates the airways to improve breathing and narrows blood vessels in the skin and intestine so that an increased flow of blood reaches the muscles and allows them to cope with the demands of exercise.
Alpha-fetoprotein (AFP)
A protein produced by a developing fetus that is present in amniotic fluid and, in smaller amounts, in a pregnant woman's blood. Abnormal levels of AFP found in a blood test between the 15th and 18th weeks of pregnancy can indicate abnormalities in the fetus.
