Phenothiazine
Phenothiazine, abbreviated PTZ, is an organic compound that has the formula S(C6H4)2NH and is related to the thiazine-class of heterocyclic compounds. Derivatives of phenothiazine are highly bioactive and have widespread use and rich history. The derivatives chlorpromazine and promethazine revolutionized the fields of psychiatry and allergy treatment, respectively. An earlier derivative, methylene blue, was one of the first antimalarial drugs, and derivatives are under investigation as possible anti-infective drugs. Phenothiazine is a prototypical pharmaceutical lead structure in medicinal chemistry. Uses Phenothiazine itself is only of theoretical interest, but its derivatives revolutionized psychiatry, other fields of medicine, and pest management. Other derivatives have been studied for possible use in advanced batteries and fuel cells. Phenothiazine-derived drugs In 1876, methylene blue, a derivative of phenothiazine, was synthesized by Heinrich Caro at BASF. The st ...

Petrozavodsk
Petrozavodsk (russian: Петрозаводск, p=pʲɪtrəzɐˈvotsk; Karelian, Vepsian and fi, Petroskoi) is the capital city of the Republic of Karelia, Russia, which stretches along the western shore of Lake Onega for some . The population of the city was 280,890 as of 2022. Etymology The name of the city is a combination of words Peter (Peter the Great) and ''zavod'' (meaning factory). It was previously known as ''Shuysky Zavod'' (1703–1704) and ''Petrovskaya Sloboda'' (1704–1777), which was the first name of the city related to Peter the Great. It was renamed to Petrozavodsk after Catherine the Great granted the settlement the status of a city. An ancient Swedish name was ''Onegaborg'', known from a map from 1592 of the Flemish cartographer Abraham Ortelius, and hence translated to Finnish as ''Äänislinna'', a name used during the occupation of Eastern Karelia by Finnish forces during the Continuation War (1941–1944) in the context of World War II.

Pentylenetetrazol
Pentylenetetrazol, also known as pentylenetetrazole, leptazol, metrazol, pentetrazol (INN), pentamethylenetetrazol, Corazol, Cardiazol, Deumacard, or PTZ, is a drug formerly used as a circulatory and respiratory stimulant. High doses cause convulsions, as discovered by Hungarian-American neurologist and psychiatrist Ladislas J. Meduna in 1934. It has been used in convulsive therapy, and was found to be effective—primarily for depression—but side effects such as uncontrolled seizures were difficult to avoid. In 1939, pentylenetetrazol was replaced by electroconvulsive therapy, which is easier to administer, as the preferred method for inducing seizures in England's mental hospitals. In the US, its approval by the Food and Drug Administration was revoked in 1982. It is used in Italy as a cardio-respiratory stimulant in combination with codeine in a cough suppressant drug. Mechanism The mechanism of pentylenetetrazol is not well understood, and it may have multiple mechanisms ...

Pacific Time Zone
The Pacific Time Zone (PT) is a time zone encompassing parts of western Canada, the western United States, and western Mexico. Places in this zone observe standard time by subtracting eight hours from Coordinated Universal Time ( UTC−08:00). During daylight saving time, a time offset of UTC−07:00 is used. In the United States and Canada, this time zone is generically called the Pacific Time Zone. Specifically, time in this zone is referred to as Pacific Standard Time (PST) when standard time is being observed (early November to mid-March), and Pacific Daylight Time (PDT) when daylight saving time (mid-March to early November) is being observed. In Mexico, the corresponding time zone is known as the ''Zona Noroeste'' (Northwest Zone) and observes the same daylight saving schedule as the U.S. and Canada. The largest city in the Pacific Time Zone is Los Angeles, whose metropolitan area is also the largest in the time zone. The zone is two hours ahead of the Hawaii–Ale ...
