Tricyclic Antidepressant
Tricyclic antidepressants (TCAs) are a class of medications that are used primarily as antidepressants. TCAs were discovered in the early 1950s and were marketed later in the decade. They are named after their chemical structure, which contains three rings of atoms. Tetracyclic antidepressants (TeCAs), which contain four rings of atoms, are a closely related group of antidepressant compounds. Although TCAs are sometimes prescribed for depressive disorders, they have been largely replaced in clinical use in most parts of the world by newer antidepressants such as selective serotonin reuptake inhibitors (SSRIs), serotonin–norepinephrine reuptake inhibitors (SNRIs) and norepinephrine reuptake inhibitors (NRIs). Adverse effects have been found to be of a similar level between TCAs and SSRIs. Medical uses The TCAs are used primarily in the clinical treatment of mood disorders such as major depressive disorder (MDD), dysthymia, and treatment-resistant variants. They are also ...

Trans-Canada Air Lines
Trans-Canada Air Lines (also known as TCA in English, and Trans-Canada in French) was a Canadian airline that operated as the country's flag carrier, with corporate headquarters in Montreal, Quebec. Its first president was Gordon Roy McGregor. Founded in 1937, it was renamed Air Canada in 1965. History With heavy involvement from C. D. Howe, a senior minister in the Mackenzie King cabinet, TCA was created by the Crown Corporation Canadian National Railway (CNR), and launched its first flight on 1 September 1937, on a flight between Vancouver and Seattle. An air-mail contract with Royal Mail Canada was one of the methods by which TCA was financed. The creation of TCA was partly by CNR management who wanted to expand the company into the new field of passenger aviation, and was partly by government direction. Prior to TCA, no large national airline existed in Canada. With war looming, and other nations (primarily the U.S.) experiencing major increases in the creation of passen ...

True Cost Accounting
True Cost Accounting (TCA) is an accounting approach that measures and values the hidden impacts of economic activities on the Natural environment, environment, society and health. TCA is also referred to as full cost accounting (FCA) or “multiple capital accounting (MCA)”. The approach moves beyond purely economic thinking with the aim of improving decision-making in commercial organizations and in public policy. It includes accounting for natural capital, human capital, social capital and produced capital. The True Cost Accounting approach can be applied to every sector of the economy. It aims to reveal the impacts of economic activities on society as a whole, in addition to the private costs directly incurred by producers and consumers. These can be environmental, health or social impacts that are not reflected in the market prices of products and services, i.e. not included in the operational profit and loss accounts, and so are regarded as hidden. True Cost Accounting is of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tricarboxylic Acid Cycle
The citric acid cycle—also known as the Krebs cycle, Szent–Györgyi–Krebs cycle, or TCA cycle (tricarboxylic acid cycle)—is a series of biochemical reactions that release the energy stored in nutrients through acetyl-CoA oxidation. The energy released is available in the form of ATP. The Krebs cycle is used by organisms that generate energy via respiration, either anaerobically or aerobically (organisms that ferment use different pathways). In addition, the cycle provides precursors of certain amino acids, as well as the reducing agent NADH, which are used in other reactions. Its central importance to many biochemical pathways suggests that it was one of the earliest metabolism components. Even though it is branded as a "cycle", it is not necessary for metabolites to follow a specific route; at least three alternative pathways of the citric acid cycle are recognized. Its name is derived from the citric acid (a tricarboxylic acid, often called citrate, as the ioniz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transportation Corridor Agencies
Transportation Corridor Agencies (TCA) are two joint powers authorities formed by the California State Legislature in 1986 to plan, finance, construct, and operate Orange County's toll roads. TCA consists of two local government agencies: * The San Joaquin Hills Transportation Corridor Agency which oversees the San Joaquin Hills Toll Road (State Route 73). * The Foothill/Eastern Transportation Corridor Agency which runs both the Foothill Toll Road (State Route 241) and the Eastern Toll Road ( State Route 241 and State Route 261). The toll roads maintained by TCA are financed with tax-exempt bonds on a stand-alone basis—taxpayers are not responsible for repaying any debt if toll revenues fall short. Some California lawmakers and toll road advocates favor using similar local agencies to build and maintain tollways, especially after the controversy of authorizing a private company to initially run the 91 Express Lanes. Others oppose them, arguing that new toll roads wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trichloroacetic Acid
Trichloroacetic acid (TCA; TCAA; also known as trichloroethanoic acid) is an analogue of acetic acid in which the three hydrogen atoms of the methyl group have all been replaced by chlorine atoms. Salts and esters of trichloroacetic acid are called trichloroacetates. Synthesis Trichloroacetic acid was discovered by Jean-Baptiste Dumas in 1830. It is prepared by the reaction of chlorine with acetic acid in the presence of a suitable catalyst such as red phosphorus. This reaction is Hell–Volhard–Zelinsky halogenation. : + 3 → + 3 Another route to trichloroacetic acid is the oxidation of trichloroacetaldehyde. Use It is widely used in biochemistry for the precipitation of macromolecules, such as proteins, DNA, and RNA. TCA and DCA are both used in cosmetic treatments (such as chemical peels and tattoo removal) and as topical medication for chemoablation of warts, including genital warts. It can kill normal cells as well. It is considered safe for use fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
