Hypothermia is used widely during open heart surgery due to its cytoprotective effects. In addition to this, other mechanisms of therapeutic hypothermia include suppression of free radicals, inhibition of destructive enzymatic reactions, reduction in metabolic requirements in low-flow regions, and inhibition of the biosynthesis, release, and uptake of excitatory neurotransmitters. Through these mechanisms, hypothermia provides a favorable balance between oxygen supply and demand, slows the onset of ischemic depolarization, decreases the release of ischemic-induced intracellular calcium influx, and suppresses nitric oxide synthase activity.
Hypothermia is widely used in open cardiac surgery not only to protect against perioperative brain ischemia that could potentially develop, but also the myocardium.
Until 1921, the Russian economy was completely mutilated and destroyed by war communism. Socialism did not start in good light, so Lenin became worried about the overall state of the economy. the war of communism that lasted from 1918 to 1921 brought the economy to a complete collapse. In March 1921, the Kronshtadt Rebellion happened, which convinced Lenin that changes in the economy should be made. Thus, in 1922. he revised economic policy and introduced the so-called new economic policy (NEP). The peasants were allowed to sell part of their property for profit, and traders were allowed to engage in business. He was thinking that it would last for decades, but only seven years later in 1928. Lenin's successor, Stalin, centralized the economy and again nationalized a huge part of the economy.
Bills and coins that a country actually circulates is called circulation currency. This is money that is used to conduct transactions between consumers and businesses for goods and services. Money that is kept in a bank and in long term investments are not a part of circulation currency because it cannot directly be used for day to day transactions.
