A plant family of the order Dipsacales, subclass Asteridae, class Magnoliopsida.
A genus of the family POXVIRIDAE, subfamily CHORDOPOXVIRINAE, comprising poxviruses infecting sheep, goats, and cattle. Transmission is usually mechanical by arthropods, but also includes contact, airborne routes, and non-living reservoirs (fomites).
Derivatives of caproic acid. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain a carboxy terminated six carbon aliphatic structure.
Cyclic amide of caproic acid used in manufacture of synthetic fibers of the polyamide type. Can cause local irritation.
Derivatives of caprylic acid. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain a carboxy terminated eight carbon aliphatic structure.
An alkylamide found in CAPSICUM that acts at TRPV CATION CHANNELS.
A plant genus of the family CRUCIFERAE.
A plant genus of the family SOLANACEAE. The hot peppers yield CAPSAICIN, which activates VANILLOID RECEPTORS. Several varieties have sweet or pungent edible fruits that are used as vegetables when fresh and spices when the pods are dried.
The outer protein protective shell of a virus, which protects the viral nucleic acid. Capsids are composed of repeating units (capsomers or capsomeres) of CAPSID PROTEINS which when assembled together form either an icosahedral or helical shape.
Proteins that form the CAPSID of VIRUSES.
A pill sized videocamera encased in a capsule. It is designed to be swallowed and subsequently traverse the gastrointestinal tract while transmitting diagnostic images along the way.
Non-invasive, endoscopic imaging by use of VIDEO CAPSULE ENDOSCOPES to perform examination of the gastrointestinal tract, especially the small bowel.
Clouding or loss of transparency of the posterior lens capsule, usually following CATARACT extraction.
Hard or soft soluble containers used for the oral administration of medicine.
The making of a continuous circular tear in the anterior capsule during cataract surgery in order to allow expression or phacoemulsification of the nucleus of the lens. (Dorland, 28th ed)
One of the phthalimide fungicides.
A potent and specific inhibitor of PEPTIDYL-DIPEPTIDASE A. It blocks the conversion of ANGIOTENSIN I to ANGIOTENSIN II, a vasoconstrictor and important regulator of arterial blood pressure. Captopril acts to suppress the RENIN-ANGIOTENSIN SYSTEM and inhibits pressure responses to exogenous angiotensin.
RefSeq NM_007608
associated with carbapenem resistance; RefSeq YP_001847472
A plant genus of the family FABACEAE. Members contain STILBENES.
A slowly hydrolyzed CHOLINERGIC AGONIST that acts at both MUSCARINIC RECEPTORS and NICOTINIC RECEPTORS.
An antibacterial agent that has been used in veterinary practice for treating swine dysentery and enteritis and for promoting growth. However, its use has been prohibited in the UK following reports of carcinogenicity and mutagenicity. (From Martindale, The Extra Pharmacopoeia, 30th ed, p125)
Derivatives of carbamic acid, H2NC(=O)OH. Included under this heading are N-substituted and O-substituted carbamic acids. In general carbamate esters are referred to as urethanes, and polymers that include repeating units of carbamate are referred to as POLYURETHANES. Note however that polyurethanes are derived from the polymerization of ISOCYANATES and the singular term URETHANE refers to the ethyl ester of carbamic acid.
A dibenzazepine that acts as a sodium channel blocker. It is used as an anticonvulsant for the treatment of grand mal and psychomotor or focal SEIZURES. It may also be used in the management of BIPOLAR DISORDER, and has analgesic properties.
Substances and drugs that stimulate the synthesis or increase the activity of CARBAMOYL PHOSPHATE SYNTHETASE I. Drugs in this class of compounds have been used to treat the genetic disorder, CARBAMOYL-PHOSPHATE SYNTHASE I DEFICIENCY DISEASE.
An enzyme that catalyzes the formation of carbamoyl phosphate from ATP, carbon dioxide, and ammonia. This enzyme is specific for arginine biosynthesis or the urea cycle. Absence or lack of this enzyme may cause CARBAMOYL-PHOSPHATE SYNTHASE I DEFICIENCY DISEASE. EC 6.3.4.16.
An enzyme that catalyzes the formation of carbamoyl phosphate from ATP, carbon dioxide, and glutamine. This enzyme is important in the de novo biosynthesis of pyrimidines. EC 6.3.5.5.
A urea cycle disorder manifesting in infancy as lethargy, emesis, seizures, alterations of muscle tone, abnormal eye movements, and an elevation of serum ammonia. The disorder is caused by a reduction in the activity of hepatic mitochondrial CARBAMOYL-PHOSPHATE SYNTHASE (AMMONIA). (Menkes, Textbook of Child Neurology, 5th ed, pp50-1)
The monoanhydride of carbamic acid with PHOSPHORIC ACID. It is an important intermediate metabolite and is synthesized enzymatically by CARBAMYL-PHOSPHATE SYNTHASE (AMMONIA) and CARBAMOYL-PHOSPHATE SYNTHASE (GLUTAMINE-HYDROLYZING).
Compounds consisting of two phenyl groups joined by a urea. Derivatives may be used as ANTIPARASITIC AGENTS.
A group of beta-lactam antibiotics in which the sulfur atom in the thiazolidine ring of the penicillin molecule is replaced by a carbon atom. THIENAMYCINS are a subgroup of carbapenems which have a sulfur atom as the first constituent of the side chain.
A carbamate insecticide and parasiticide. It is a potent anticholinesterase agent belonging to the carbamate group of reversible cholinesterase inhibitors. It has a particularly low toxicity from dermal absorption and is used for control of head lice in some countries.
Sugar analogs in which the ring oxygen is replaced by a methylene (CH2) carbon.
An alkylating agent structurally similar to MITOMYCIN and found to be effective in the treatment of leukemia and various other neoplasms in mice. It causes leukemia and thrombocytopenia in almost all human patients.
Benzo-indoles similar to CARBOLINES which are pyrido-indoles. In plants, carbazoles are derived from indole and form some of the INDOLE ALKALOIDS.
Broad-spectrum semisynthetic penicillin derivative used parenterally. It is susceptible to gastric juice and penicillinase and may damage platelet function.
An agent derived from licorice root. It is used for the treatment of digestive tract ulcers, especially in the stomach. Antidiuretic side effects are frequent, but otherwise the drug is low in toxicity.
An inhibitor of DOPA DECARBOXYLASE that prevents conversion of LEVODOPA to dopamine. It is used in PARKINSON DISEASE to reduce peripheral adverse effects of LEVODOPA. It has no anti-parkinson activity by itself.
An imidazole antithyroid agent. Carbimazole is metabolized to METHIMAZOLE, which is responsible for the antithyroid activity.
Compounds that contain three methine groups. They are frequently used as cationic dyes used for differential staining of biological materials.
A compound formed when iodoacetic acid reacts with sulfhydryl groups in proteins. It has been used as an anti-infective nasal spray with mucolytic and expectorant action.
Compounds with the general formula RN=C=NR, where R is a hydrocarbyl group.
