Streptomyces Hygroscopicus
''Streptomyces hygroscopicus'' is a bacterial species in the genus '' Streptomyces''. It was first described by Hans Laurits Jensen in 1931. Biochemistry Cultures of different strains of ''S. hygroscopicus'' can be used to produce several chemical compounds or enzymes. Small molecules Immunosuppressants Sirolimus (also known as rapamycin) is an antifungal and immunosuppressant that has been isolated from ''S. hygroscopicus'' from soil samples from Easter Island. Ascomycin is another immunosuppressant produced by some strains of ''S. hygroscopicus;'' it has a similar structure to sirolimus and can be used to treat autoimmune diseases and skin diseases and can help prevent rejection after an organ transplant. Antibiotics The antibiotics geldanamycin, hygromycin B, nigericin, validamycin, and cyclothiazomycin are found in ''S. hygroscopicus''. Experimental cancer drugs Indolocarbazoles can be found in ''S. hygroscopicus'' . Anthelmintics and insecticides Mi ...

People From Khushab District
The term "the people" refers to the public or Common people, common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of Person, persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Declaration on the Rights of Indigenous Peoples, Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independence, independent sovereignty and therefore secession. Indeed, judge Ivor Jennings i ...

Canadian Microbiologists
Canadians () are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity and Canadian values. Canada has also been strongly influenced by its linguistic, geographic, an ...

Sirolimus
Sirolimus, also known as rapamycin and sold under the brand name Rapamune among others, is a macrolide compound that is used to coat coronary stents, prevent organ transplant rejection, treat a rare lung disease called lymphangioleiomyomatosis, and treat perivascular epithelioid cell tumour (PEComa). It has immunosuppressant functions in humans and is especially useful in preventing the rejection of kidney transplants. It is a mammalian target of rapamycin (mTOR) kinase inhibitor that reduces the sensitivity of T cells and B cells to interleukin-2 (IL-2), inhibiting their activity. This compound also has a use in cardiovascular drug-eluting stent technologies to inhibit restenosis. It is produced by the bacterium '' Streptomyces hygroscopicus'' and was isolated for the first time in 1972, from samples of ''Streptomyces hygroscopicus'' found on Easter Island. The compound was originally named rapamycin after the native name of the island, Rapa Nui. Sirolimus was initially deve ...

Easter Island
Easter Island (, ; , ) is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is renowned for its nearly 1,000 extant monumental statues, called ''moai'', which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park. Experts differ on when the island's Polynesian inhabitants first reached the island. While many in the research community cited evidence that they arrived around the year 800, a 2007 study provided compelling evidence suggesting their arrival was closer to 1200. The inhabitants created a thriving and industrious culture, as evidenced by the island's numerous enormous stone ''moai'' and other artifacts. Land clearing for cultivation and the introduction of the Polynesian rat led to gradual deforestation. By the time of European arrival in 1722, the i ...

Partition Of India
The partition of India in 1947 was the division of British India into two independent dominion states, the Dominion of India, Union of India and Dominion of Pakistan. The Union of India is today the Republic of India, and the Dominion of Pakistan is the Islamic Republic of Pakistan and the People's Republic of Bangladesh. The Partition (politics), partition involved the division of two provinces, Bengal and the Punjab Province (British India), Punjab, based on district-wise Hindu or Muslim majorities. It also involved the division of the British Indian Army, the Royal Indian Navy, the Indian Civil Service, the History of rail transport in India, railways, and the central treasury, between the two new dominions. The partition was set forth in the Indian Independence Act 1947 and resulted in the dissolution of the British Raj, or Crown rule in India.
