" Schwan belongs to the German tradition of social democratic opposition to Karl Marx's theories. In September 1974, she was one of the founding members of the ""Seeheimer Kreis"", a conservative think tank within the SPD. She became a member of the SPD ""Grundwertekommission"" (Commission for Fundamental Values) in 1977. In 1984, she was removed from this position after criticizing the party's ""Ostpolitik"" as cooperating too closely with communist governments, while not engaging enough with dissidents. Rather she sought for support and dialog with those Eastern Europeans who would dare to criticize their governments. Schwan was reinstated in the ""Grundwertekommission"" in 1996. Since 2002, she has presided over the ""German-Polish Forum"" together with Janusz Reiter. In November 2004, the German government under Gerhard Schröder appointed her to the newly created office of the co-ordinator for cooperation with Poland (her counterpart on the Polish side was then Irena Lipowicz). She retained this position when the government changed and became headed by Christian Democrat Angela Merkel. In February 2009, she criticized Schröder for being too uncritical towards Vladimir Putin and too insensitive about Polish concerns about closer German-Russian ties.

" On 15 September 2010, Schwan supported the new initiative Spinelli Group in the European Parliament, which was founded to reinvigorate the strive for federalisation of the European Union (EU). Other prominent supporters are: Jacques Delors, Daniel Cohn-Bendit, Guy Verhofstadt, Jo Leinen, Andrew Duff, and Elmar Brok.
|
"
|
" On 23 May 2004, Schwan was the SPD candidate for the German presidential election. She received 589 votes in the ""Bundesversammlung"" (Federal Assembly) but was defeated by Horst Köhler who won 604 votes from the 1205 delegates. On 26 May 2008, SPD chairman Kurt Beck announced Schwan's renewed nomination for the upcoming presidential elections in 2009. Once again she competed with Horst Köhler, who announced his renewed candidacy on 22 May 2008.

|
" In the event Köhler was re-elected to a second term over Schwan.
|
"
|
" In the 2019 SPD leadership election, Schwan announced her intention to run for the position as the party's co-chair, together with Ralf Stegner.
|
"
|
" Ahead of the 2009 presidential election, Schwan was criticized by the Federal Commissioner for the Stasi Records, Marianne Birthler, for statements on the political regime of East Germany. Reportedly, several electors from the Green Party refused to vote for Schwan due to her statements regarding the communist state.

" The name Kay is found both as a surname (see Kay (surname)) and as a given name. In English-speaking countries, it is usually a feminine name, often a short form of Katherine or one of its variants; but it is also used as a first name in its own right, and also as a masculine name (for example in India, the Netherlands, and Sweden). The alternative spelling of Kaye is encountered as a surname, but also occasionally as a given name: for instance, actress Kaye Ballard.

"= = = Macula densa = = =
|
"
|
"
|
"
|
" In the kidney, the macula densa is an area of closely packed specialized cells lining the wall of the distal tubule, at the point where the thick ascending limb meets the distal convoluted tubule. The macula densa is the thickening where the distal tubule touches the glomerulus.
|
"
|
" The cells of the macula densa are sensitive to the concentration of sodium chloride in the distal convoluted tubule. A decrease in sodium chloride concentration initiates a signal from the macula densa that has two effects:
|
"
|
"(1) it decreases resistance to blood flow in the afferent arterioles, which raises glomerular hydrostatic pressure and helps return the glomerular filtration rate (GFR) toward normal, and
|
"
|
"(2) it increases renin release from the juxtaglomerular cells of the afferent and efferent arterioles, which are the major storage sites for renin.
|
"
|
" As such, an increase in sodium chloride concentration would result in vasoconstriction of afferent arterioles, and reduced paracrine stimulation of juxtaglomerular cells. This demonstrates the macula densa feedback, where compensatory mechanisms act in order to return GFR to normal.
|
"
|
" The release of renin is an essential component of the renin–angiotensin–aldosterone system (""RAAS""), which regulates blood pressure and volume.
|
"
|
" The cells of the macula densa are taller and have more prominent nuclei than surrounding cells of the distal straight tubule (cortical thick ascending limb).
|
"
|
" The close proximity and prominence of the nuclei cause this segment of the distal tubule wall to appear darker in microscopic preparations, hence the name ""macula densa"".
|
"
|
" Macula densa cells sense changes in sodium chloride level, and will trigger an autoregulatory response to increase or decrease reabsorption of ions and water to the blood (as needed) in order to alter blood volume and return blood pressure to normal.
|
"
|
" A decrease in afferent arteriole diameter causes a decrease in the GFR (glomerular filtration rate), resulting in a decreased concentration of sodium and chloride ions in the filtrate and/or decreased filtrate flow rate. Reduced blood pressure means decreased venous pressure and, hence, a decreased peritubular capillary pressure. This results in a smaller capillary hydrostatic pressure, which causes an increased absorption of sodium ions into the vasa recta at the proximal tubule.
|
"
|
" Hence, a decrease in blood pressure results in less sodium chloride present at the distal tubule, where the macula densa is located. The macula densa senses this drop in salt concentration and responds through two mechanisms, both of which are mediated by prostaglandin release. First, prostaglandins preferentially vasodilate the renal afferent arteriole, decreasing afferent arteriole resistance and, thus, offsetting the decrease in glomerular hydrostatic pressure caused by the drop in blood pressure. Second, prostaglandin activates prostaglandin-sensitive specialized smooth muscle cells of the renal afferent arterioles, juxtaglomerular cells (JG cells), to release renin into the bloodstream. The JG cells can also release renin independently of the macula densa. There are stretch-sensitive baroreceptors lining the arterioles that will release renin if a fall in blood pressure (i.e. decreased stretch of arteriole due to less blood flow) in the arterioles is detected. Furthermore, JG cells contain beta-1 adrenergic receptors, and so activation of the sympathetic nervous system will further stimulate renin release.
|
"
|
" Thus, a drop in blood pressure results in preferential vasodilation of the afferent arterioles, increasing renal blood flow (RBF), renal plasma flow (RPF) and GFR due to greater blood flow to the glomerulus. Note that there is no change in filtration fraction, as both GFR and RPF are increased. It also results in the release of renin, which, through the renin–angiotensin system, causes constriction of the efferent arterioles, which ultimately increases hydrostatic pressure in the glomerulus.
|
"
|
" The process triggered by the macula densa helps keep the GFR fairly steady in response to varying artery pressure.
|
"
|
" Damage to the macula densa would impact blood flow to the kidneys because the afferent arterioles would not dilate in response to a decrease in filtrate osmolarity and pressure at the glomerulus would not be increased. As part of the body's blood pressure regulation, the macula densa monitors filtrate osmolarity; if it falls too far, the macula densa causes the afferent arterioles of the kidney to dilate, thus increasing the pressure at the glomerulus and increasing the glomerular filtration rate.

" Cottesloe is a western suburb of Perth, Western Australia, within the Town of Cottesloe. Cottesloe was named for Thomas Fremantle, 1st Baron Cottesloe, a prominent Tory politician and the brother of Admiral Sir Charles Fremantle for whom the city of Fremantle was named. The nearby suburb of Swanbourne was named for the Fremantle family seat, Swanbourne House, in Swanbourne, Buckinghamshire.
|
"
|
" Cottesloe was home to Australian Prime Minister John Curtin. The house he built still stands in Jarrad Street. It is now vested jointly in the National Trust of Australia (WA) and Curtin University.
|
"
|
" Cottesloe is a beach-side suburb of the city of Perth in Western Australia. It is located roughly halfway between Perth central business district and the port of Fremantle. It is famous for its beaches, cafes and relaxed lifestyle.
|
"
|
" Cottesloe is bounded by the Indian Ocean to the west; a line extending from Boundary Road, Mosman Park to the ocean to the south; the Perth-Femantle Railway, Stirling Highway, Congdon Street and West Coast Highway to the east; and North Street to the north. Cottesloe is generally residential, with a significant shopping area located between Jarrad and Station streets adjacent to the Cottesloe railway station.
|
"
|
" In the 2016 census, there were 7,375 people in Cottesloe. 68.8% of people were born in Australia. The most common other countries of birth were England 8.6%, South Africa 1.8%, New Zealand 1.6% and United States of America 1.4%. 86.6% of people spoke only English at home. The most common responses for religion were No Religion 36.4%, Anglican 22.6% and Catholic 19.3%.
|
"
|
" Of the occupied private dwellings in Cottesloe, 66.9% were separate houses, 14.9% were semi-detached, row or terrace houses, townhouses etc., and 18.1% were flat or apartments.
|
"
|
" Of the employed people in Cottesloe, 7.2% worked in hospitals (except psychiatric hospitals). Other major industries of employment included legal services 3.6% and general practice medical services 3.0%.
|
"
|
" Historically the beach and its panorama are reflections of the changes in the last 110 years of Perth's history. The photos and paintings of Cottesloe Beach that are either in collections or published, give tangible evidence of the importance of beach-oriented activities in the Perth community. Cottesloe Beach is a popular place for beach cricket. An oceanway allows pedestrians and cyclists to move along the beaches in a sustainable manner.
|
"
|
" In 2009, ""Lonely Planet"" named Cottesloe Beach the world's 2nd best beach for families.
|
"
|
" A new town planning scheme was approved for Cottesloe allowing developers to build to five storeys high along Marine Terrace with the Ocean Beach Hotel site allowed to reach eight storeys. The decision followed a two decade long debate.
|
"
|
" Cottesloe is served by Swanbourne, Grant Street, Cottesloe, Mosman Park and Victoria Street railway stations on the Fremantle line. Various bus routes along Stirling Highway and through the suburb's western and eastern sections link Cottesloe to Perth and Fremantle. All services are operated by the Public Transport Authority. During the summer months, the council provides a free shuttle bus every hour during the day, called the Cott Cat, between Cottesloe train station and the Cottesloe beachfront. In 2004 the service carried over 30,000 passengers, at a cost of $15,000.
|
"
|
" Cottesloe is part of the federal division of Curtin. From 1901 to 1968 and from 1974 to 1980 it was part of the Fremantle electorate. Curtin is regarded as a safe seat for the centre right Liberal Party, which has held the seat continually since its inception, with the exception of a period from 1996 to 1998 when former Liberal member Allan Rocher held the seat as an independent. The current member is Celia Hammond. In the parliament of Western Australia, the Legislative Assembly electoral district of Cottesloe is held by David Honey, also of the Liberal Party.
|
"
|
" John Curtin, Prime Minister of Australia for much of World War II, was local federal member of parliament from 1928 to 1931 and 1934 to 1945. He lived in Cottesloe from 1918 until his death in office in 1945. Curtin's house in Jarrad Street is vested in the National Trust of Australia (WA) and Curtin University. During 2008 there was a suggestion that the house be relocated to the Curtin University grounds but the decision was made that the house remain in Cottesloe. In May 2009 the federal government announced that it would provide a grant of $580,000 to the National Trust to restore the house.

" Claude de Bernales was a mining entrepreneur who in 1911 bought Attorney-General Richard Pennefather's 1898 Federation Queen Anne house, naming it ""Overton Lodge"". In 1936 it was rebuilt as a 30-room Inter-war Spanish Mission style residence, designed by Bernard Evans. It was bought for £30,000 by the Town of Cottesloe in 1950 and renamed the ""Cottesloe War Memorial Town Hall and Civic Centre"".

" In December 2008 the Town voted to restore the pylon, a concrete structure built in 1935, at a cost of $172,000. Decades of battering by the ocean has eroded the pylon, which was one of three pylons built to anchor a shark net following a fatal attack in 1925. Two were destroyed by storms in 1937. Since then it has become an iconic landmark and popular diving platform for beach users.
|
"
|
" During major storm activity on 21–22 May 2009, the spike was knocked off the pylon. However this is not the first time this has occurred; during storms in 1995, the spike was also knocked over. It then remained on the bottom of the ocean in approximately 3 metres of water until an unnamed group removed the structure using nothing but wood and rope.
|
"
|
" After the pylon was restored, it was painted in the Cottesloe Surf Lifesaving Club colours, but it was soon changed to the colours of North Cottesloe Lifesaving Club. It has alternated colours many times since.
