Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain, fever, and inflammation. This includes painful menstrual periods, migraines, and rheumatoid arthritis. It may also be used to close a patent ductus arteriosus in a premature baby. It can be used orally or intravenously. It typically begins working within an hour.
The Noctilucales are an order of marine dinoflagellates. They differ from most others in that the mature cell is diploid and its nucleus does not show a dinokaryotic organization. They show gametic meiosis.
The Journal of Theoretical Biology is a biweekly peer-reviewed scientific journal covering theoretical biology, as well as mathematical, computational, and statistical aspects of biology. Some research areas covered by the journal include cell biology, evolutionary biology, population genetics, morphogenesis, and immunology.
Chlorphenamine, also known as chlorpheniramine, is an antihistamine used to treat the symptoms of allergic conditions such as allergic rhinitis. It is taken orally. The medication takes effect within two hours and lasts for about 4–6 hours. It is a first-generation antihistamine and works by blocking the H1 receptor.
ATC code P01Antiprotozoals is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. Subgroup P01 is part of the anatomical group P Antiparasitic products, insecticides and repellents.
l-DOPA, also known as levodopa and l-3,4-dihydroxyphenylalanine, is made and used as part of the normal biology of some plants and animals, including humans. Humans, as well as a portion of the other animals that utilize l-DOPA, make it via biosynthesis from the amino acid l-tyrosine. l-DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines. Furthermore, l-DOPA itself mediates neurotrophic factor release by the brain and CNS. In some plant families, l-DOPA is the central precursor of a biosynthetic pathway that produces a class of pigments called betalains. l-DOPA can be manufactured and in its pure form is sold as a psychoactive drug with the INN levodopa; trade names include Sinemet, Pharmacopa, Atamet, and Stalevo. As a drug, it is used in the clinical treatment of Parkinson's disease and dopamine-responsive dystonia.
The Hong Kong flu, also known as the 1968 flu pandemic, was a flu pandemic that occurred in 1968 and 1969 and which killed between one and four million people globally. It is among the deadliest pandemics in history, and was caused by an H3N2 strain of the influenza A virus. The virus was descended from H2N2 through antigenic shift, a genetic process in which genes from multiple subtypes are reassorted to form a new virus.
Cannabidivarin (CBDV, GWP42006) is a non-intoxicating psychoactive cannabinoid found in Cannabis. It is a homolog (chemistry) of cannabidiol (CBD), with the side-chain shortened by two methylene bridges (CH2 units).
Vulimiri Ramalingaswami was an Indian medical scientist, pathologist and medical writer. His pioneering research on nutrition got him elected to the National Academy of Sciences, Russian Academy of Medical Sciences and the Royal Society of London.
Nomifensine (Merital, Alival) is a norepinephrine-dopamine reuptake inhibitor, i.e. a drug that increases the amount of synaptic norepinephrine and dopamine available to receptors by blocking the dopamine and norepinephrine reuptake transporters. This is a mechanism of action shared by some recreational drugs like cocaine and the medication tametraline (see DRI). Research showed that the (S)-isomer is responsible for activity.
The Tektite habitat was an underwater laboratory which was the home to divers during Tektite I and II programs. The Tektite program was the first scientists-in-the-sea program sponsored nationally. The habitat capsule was placed in Great Lameshur Bay, Saint John, U.S. Virgin Islands in 1969 and again in 1970.
Cyclopentamine is a sympathomimetic alkylamine, classified as a vasoconstrictor. Cyclopentamine was indicated in the past as an over-the-counter (OTC) medication for use as a nasal decongestant, notably in Europe and Australia, but has now been largely discontinued.
The enzyme α-N-acetylglucosaminidase is a protein associated with Sanfilippo syndrome, with systematic name α-N-acetyl-D-glucosaminide N-acetylglucosaminohydrolase. It catalyses the hydrolysis of terminal non-reducing N-acetyl-D-glucosamine residues in N-acetyl-α-D-glucosaminides, and also UDP-N-acetylglucosamine.
Deoxyribonuclease IV (phage-T4-induced) is catalyzes the degradation nucleotides in DsDNA by attacking the 5'-terminal end.
ATCvet code QP51Antiprotozoals is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System for veterinary medicinal products, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products for veterinary use. Subgroup QP51 is part of the anatomical group QP Antiparasitic products, insecticides and repellents.
Caroxazone is an antidepressant which was formerly used for the treatment of depression but is now no longer marketed. It acts as a reversible monoamine oxidase inhibitor (RIMA) of both MAO-A and MAO-B subtypes, with five-fold preference for the latter.
Talsupram is a selective norepinephrine reuptake inhibitor (NRI) which was investigated as an antidepressant in the 1960s and 1970s but was never marketed. Along with talopram, it is structurally related to the selective serotonin reuptake inhibitor (SSRI) citalopram.
Pelanserin (TR2515) is a chemical compound that acts as an antagonist of the 5-HT2 and α1-adrenergic receptors.
WB-4101 is a compound which acts as an antagonist at the α1B-adrenergic receptor. It was one of the first selective antagonists developed for this receptor and was invented in 1969, but is still commonly used in research into adrenergic receptors, especially as a lead compound from which to develop more selective drugs.
Estrofurate, also known as 17α-(3-furyl)-estra-1,3,5(10),7-tetraene-3,17-diol 3-acetate, is a synthetic, steroidal estrogen that was synthesized in 1967 and studied in the late 1960s and early 1970s but was never marketed. It is a relatively weak estrogen in bioassays.
