PGF2alpha
Prostaglandin F2α (PGF2α in prostanoid nomenclature), pharmaceutically termed carboprost is a naturally occurring prostaglandin used in medicine to induce labor and as an abortifacient. Prostaglandins are lipids throughout the entire body that have a hormone-like function. In pregnancy, PGF2 is medically used to sustain contracture and provoke myometrial ischemia to accelerate labor and prevent significant blood loss in labor. Additionally, PGF2 has been linked to being naturally involved in the process of labor. It has been seen that there are higher levels of PGF2 in maternal fluid during labor when compared to at term. This signifies that there is likely a biological use and significance to the production and secretion of PGF2 in labor. Prostaglandin is also used to treat uterine infections in domestic animals. In domestic mammals, it is produced by the uterus when stimulated by oxytocin, in the event that there has been no implantation during the luteal phase. It acts on t ...

Prostaglandin F2α Receptor
Prostaglandin F receptor (FP) is a receptor (biochemistry), receptor belonging to the prostaglandin receptor, prostaglandin (PG) group of receptors. FP binds to and mediates the biological actions of Prostaglandin F2alpha, Prostaglandin F2α (PGF2α). It is encoded in humans by the ''PTGFR'' gene. Gene The ''PTGFR'' gene is located on human chromosome 1 at position p31.1 (i.e. 1p31.1), contains 7 exons, and codes for a G protein coupled receptor (GPCR) of the rhodopsin-like receptor family, Subfamily A14 (see rhodopsin-like receptors#Subfamily A14). ''PTGFR'' is expressed as two Alternative splicing, alternatively spliced transcript variants encoding different isoforms, FPA and FPB, which have different C-terminal lengths. MicroRNA miR-590-3p binds to the Three prime untranslated region of the FP gene to repress its Translation (biology), translation. miR-590-3p thus appears to be a negative regulator of FP expression in various cell types. Expression In humans, FP mRNA and/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arachidonic Acid
Arachidonic acid (AA, sometimes ARA) is a polyunsaturated omega-6 fatty acid 20:4(ω-6), or 20:4(5,8,11,14). It is structurally related to the saturated arachidic acid found in cupuaçu butter. Its name derives from the New Latin word ''arachis'' (peanut), but peanut oil does not contain any arachidonic acid. Chemistry In chemical structure, arachidonic acid is a carboxylic acid with a 20-carbon chain and four ''cis''-double bonds; the first double bond is located at the sixth carbon from the omega end. Some chemistry sources define 'arachidonic acid' to designate any of the eicosatetraenoic acids. However, almost all writings in biology, medicine, and nutrition limit the term to ''all cis''-5,8,11,14-eicosatetraenoic acid. Biology Arachidonic acid is a polyunsaturated fatty acid present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine, and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain, muscles, an ...

Prostaglandin
The prostaglandins (PG) are a group of physiologically active lipid compounds called eicosanoids having diverse hormone-like effects in animals. Prostaglandins have been found in almost every tissue in humans and other animals. They are derived enzymatically from the fatty acid arachidonic acid. Every prostaglandin contains 20 carbon atoms, including a 5-carbon ring. They are a subclass of eicosanoids and of the prostanoid class of fatty acid derivatives. The structural differences between prostaglandins account for their different biological activities. A given prostaglandin may have different and even opposite effects in different tissues in some cases. The ability of the same prostaglandin to stimulate a reaction in one tissue and inhibit the same reaction in another tissue is determined by the type of receptor to which the prostaglandin binds. They act as autocrine or paracrine factors with their target cells present in the immediate vicinity of the site of their secret ...

Intravenous Therapy
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth. It may also be used to administer medications or other medical therapy such as blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route of administration is also used for the consump ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyometra
Pyometra or pyometritis is a uterine infection. Though it is most commonly known as a disease of the unaltered female dog, it is also a notable human disease. It is also seen in female cattle, horses, goats, sheep, swine, cats, rabbits, hamsters, ferrets, rats and guinea pigs. Pyometra is an important disease to be aware of for any dog or cat owner because of the sudden nature of the disease and the deadly consequences if left untreated. It has been compared to acute appendicitis in humans, because both are essentially empyemas within an abdominal organ. Signs and symptoms The most obvious symptom of open pyometra is a discharge of pus from the vulva in a female that has recently been in heat. However, symptoms of closed pyometra are less obvious. Symptoms of both types include vomiting, loss of appetite, depression, and increased drinking and urinating. Fever is seen in less than a third of female dogs with pyometra. Closed pyometra is a more serious condition than open pyom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboprost
Carboprost (INN, trade names for the tromethamine salts Hemabate, Tham) is a synthetic prostaglandin analogue of PGF2α (specifically, it is 15-methyl-PGF2α) with oxytocic properties.

Prostaglandin Analogue
Prostaglandin analogues are a class of drugs that bind to a prostaglandin receptor. Wider use of prostaglandin analogues is limited by unwanted side effects and their abortive potential. Uses Prostaglandin analogues such as misoprostol are used in treatment of duodenal and gastric ulcers. Misoprostol and other prostaglandin analogues protect the lining of the gastrointestinal tract from harmful stomach acid and are especially indicated for the elderly on continuous doses of NSAIDs. In the field of ophthalmology, drugs of this class are used to lower intraocular pressure (IOP) in people with glaucoma. Up until the late 1970s prostaglandins were thought to raise IOP, but a paper published in 1977 showed that prostaglandin F2α lowered it, and subsequent studies found that this was due to increasing the outflow of aqueous humor, mainly by relaxing the ciliary muscle, and possibly also due to changes in extracellular matrix and to widening of spaces within the trabecular meshwork. ...

AKR1B1
Aldo-keto reductase family 1, member B1 (AKR1B1), also known as aldose reductase, is an enzyme that is encoded by the ''AKR1B1'' gene in humans. It is a reduced nicotinamide-adenine dinucleotide phosphate (NADPH)-dependent enzyme catalyzing the reduction of various aldehydes and ketones to the corresponding alcohol. The involvement of AKR1B1 in oxidative stress diseases, cell signal transduction, and cell proliferation process endows AKR1B1 with potential as a therapeutic target. Structure Gene The ''AKR1B1'' gene lies on the chromosome location of 7q33 and consists of 10 exons. There are a few putative pseudogenes for this gene, and one of them has been confirmed and mapped to chromosome 3. Protein AKR1B1 consists of 316 amino acid residues and weighs 35853Da. It does not possess the traditional dinucleotide binding fold. The way it binds NADPH differs from other nucleotide adenine dinucleotide-dependent enzymes. The active site pocket of human aldose reductase is relativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclooxygenase
Cyclooxygenase (COX), officially known as prostaglandin-endoperoxide synthase (PTGS), is an enzyme (specifically, a family of isozymes, ) that is responsible for formation of prostanoids, including thromboxane and prostaglandins such as prostacyclin, from arachidonic acid. A member of the animal-type heme peroxidase family, it is also known as prostaglandin G/H synthase. The specific reaction catalyzed is the conversion from arachidonic acid to prostaglandin H2 via a short-living prostaglandin G2 intermediate. Pharmaceutical inhibition of COX can provide relief from the symptoms of inflammation and pain. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen, exert their effects through inhibition of COX. Those that are specific to the COX-2 isozyme are called COX-2 inhibitors. The active metabolite (AM404) of paracetamol is a COX inhibitor, a fact to which some or all of its therapeutic effect has been attributed. In medicine, the root symbol "COX" is ...
