mutation in desmoplakin
An arsenical which has been used as a feed additive for enteric conditions in pigs and poultry. It causes blindness and is ototoxic and nephrotoxic in animals.
Proposed chemotherapeutic agent against filaria and trichomonas.
Oxidoreductases that specifically reduce arsenate ion to arsenite ion. Reduction of arsenate is a critical step for its biotransformation into a form that can be transported by ARSENITE TRANSPORTING ATPASES or complexed by specific sulfhydryl-containing proteins for the purpose of detoxification (METABOLIC DETOXIFICATION, DRUG). Arsenate reductases require reducing equivalents such as GLUTAREDOXIN or AZURIN.
Inorganic or organic salts and esters of arsenic acid.
Metallochrome indicator that changes color when complexed to the calcium ion under physiological conditions. It is used to measure local calcium ion concentrations in vivo.
A shiny gray element with atomic symbol As, atomic number 33, and atomic weight 75. It occurs throughout the universe, mostly in the form of metallic arsenides. Most forms are toxic. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), arsenic and certain arsenic compounds have been listed as known carcinogens. (From Merck Index, 11th ed)
Disorders associated with acute or chronic exposure to compounds containing ARSENIC (ARSENICALS) which may be fatal. Acute oral ingestion is associated with gastrointestinal symptoms and an encephalopathy which may manifest as SEIZURES, mental status changes, and COMA. Chronic exposure is associated with mucosal irritation, desquamating rash, myalgias, peripheral neuropathy, and white transverse (Mees) lines in the fingernails. (Adams et al., Principles of Neurology, 6th ed, p1212)
Inorganic or organic compounds that contain arsenic.
Efflux pumps that use the energy of ATP hydrolysis to pump arsenite across a membrane. They are primarily found in prokaryotic organisms, where they play a role in protection against excess intracellular levels of arsenite ions.
Inorganic salts or organic esters of arsenious acid.
An organoarsenic compound that was commonly used for treating SYPHILIS and other diseases.
Processes and results of aesthetic expression.
The use of art as an adjunctive therapy in the treatment of neurological, mental, or behavioral disorders.
A genus of CRUSTACEA of the order ANOSTRACA, found in briny pools and lakes and often cultured for fish food. It has 168 chromosomes and differs from most crustaceans in that its blood contains hemoglobin.
A plant genus of the family ASTERACEAE with strong-smelling foliage. It is a source of SANTONIN and other cytotoxic TERPENES.
A plant species of the genus ARTEMISIA, family ASTERACEAE that has been used in ABSINTHE. The oil contains neurotoxic 1-thujone and d-isothujone.
A plant species of the genus ARTEMISIA, family ASTERACEAE. It is the source of the antimalarial artemisinin (ANTIMALARIALS).
A group of SESQUITERPENES and their analogs that contain a peroxide group (PEROXIDES) within an oxepin ring (OXEPINS).
Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood flow through these vessels. They are also known as arterial insufficiency.
The blood pressure in the ARTERIES. It is commonly measured with a SPHYGMOMANOMETER on the upper arm which represents the arterial pressure in the BRACHIAL ARTERY.
A hereditary autosomal recessive disorder characterized by abnormal twists and turns (tortuosity) of the arteries due to excessive elongation. Affected individuals are susceptible to ANEURYSM and arterial STENOSIS and may also have respiratory, eye, facial, skin, and joint abnormalities. Mutations in the SLC2A10 gene have been identified. OMIM: 208050
The vessels carrying blood away from the heart.
Abnormal communication between two ARTERIES that may result from injury or occur as a congenital abnormality.
The smallest divisions of the arteries located between the muscular arteries and the capillaries.
Thickening of the walls of small ARTERIES or ARTERIOLES due to cell proliferation or HYALINE deposition.
Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involved, such as ATHEROSCLEROSIS with fatty lesions in the ARTERIAL INTIMA of medium and large muscular arteries.
Common occlusive arterial disease which is caused by ATHEROSCLEROSIS. It is characterized by lesions in the innermost layer (ARTERIAL INTIMA) of arteries including the AORTA and its branches to the extremities. Risk factors include smoking, HYPERLIPIDEMIA, and HYPERTENSION.
A vessel that directly interconnects an artery and a vein, and that acts as a shunt to bypass the CAPILLARY BEDS. Not to be confused with SURGICAL ANASTOMOSIS or ARTERIOVENOUS FISTULA.
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
Surgical shunt allowing direct passage of blood from an artery to a vein. (From Dorland, 28th ed)
INFLAMMATION of any ARTERIES.
