Sunao Tawara
was a Japanese pathologist known for the discovery of the atrioventricular node. Tawara was born in Ōita Prefecture and studied at the Medical School, Imperial University of Tokyo in Tokyo, graduating in 1901 and receiving his Medical Doctor, Doctorate of Medical Science in 1908. Between 1903 and 1906 he spent in Philipps University of Marburg in Marburg, studying pathology and pathological anatomy with Ludwig Aschoff. It was here he undertook his important works on pathology and anatomy of heart. Upon returning to Japan he was appointed assistant professor of pathology at Kyushu University, Kyushu Imperial University in Fukuoka, obtaining full professorship in 1908. :''Node of Tawara'': a remnant of primitive fibers found in all mammalian hearts at the base of the interauricular septum, and forming the beginning of the auriculoventricular bundle or bundle of His, which is a muscular band, containing nerve fibers, connecting the auricles with the ventricles of the heart.

Kyushu University
, abbreviated to , is a Japanese national university located in Fukuoka, on the island of Kyushu. It was the 4th Imperial University in Japan, ranked as 4th in 2020 Times Higher Education Japan University Rankings, one of the top 10 Designated National University and selected as a Top Type university of Top Global University Project by the Japanese government. Kyudai is considered one of the most prestigious research-oriented universities in Japan and is a member of the Alliance of Asian Liberal Arts Universities along with the University of Tokyo, Waseda University, Peking University and others. The history of Kyushu University can be traced back to the medical schools of the Fukuoka Domain (福岡藩 Fukuoka han) established in 1867. The school was reorganized to Fukuoka Medical College of Kyoto Imperial University in 1903 and became independent as Kyushu Imperial University in 1911. Albert Einstein visited the university on December 25, 1922. There are 2,089 foreign st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kyushu University Faculty
is the third-largest island of Japan's five main islands and the most southerly of the four largest islands ( i.e. excluding Okinawa). In the past, it has been known as , and . The historical regional name referred to Kyushu and its surrounding islands. Kyushu has a land area of and a population of 14,311,224 in 2018. In the 8th-century Taihō Code reforms, Dazaifu was established as a special administrative term for the region. Geography The island is mountainous, and Japan's most active volcano, Mount Aso at , is on Kyushu. There are many other signs of tectonic activity, including numerous areas of hot springs. The most famous of these are in Beppu, on the east shore, and around Mt. Aso in central Kyushu. The island is separated from Honshu by the Kanmon Straits. Being the nearest island to the Asian continent, historically it is the gateway to Japan. The total area is which makes it the 37th largest island in the world. It's slightly larger than Taiwan island . T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laureates Of The Imperial Prize
In English, the word laureate has come to signify eminence or association with literary awards or military glory. It is also used for recipients of the Nobel Prize, the Gandhi Peace Award, the Student Peace Prize, and for former music directors of orchestras who retain some level of involvement. History In ancient Greece, the laurel (''Laurus nobilis'') was sacred to Apollo, and as such, sprigs of it were fashioned into a crown or wreath of honor for poets and heroes. This symbolism has been widespread ever since. "Laureate letters" in old times meant the dispatches announcing a victory; and the epithet was given, even officially (e.g. to John Skelton) by universities, to distinguished poets. The name of "bacca-laureate" for a bachelor's degree shows a confusion with a supposed etymology from Latin bacca lauri (the laurel berry), which, though incorrect, involves the same idea. From the more general use of the term "poet laureate" arose its restriction in England to the of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Tokyo Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Das Reizleitungssystem Des Säugetierherzens
''Das Reizleitungssystem des Säugetierherzens'' (English: "''The Conduction System of the Mammalian Heart''") is a scientific monograph published in 1906 by Sunao Tawara. It has been recognized by cardiologists as a monumental discovery, and a milestone in cardiac electrophysiology". The monograph revealed the existence of the atrioventricular node and the function of Purkinje cells. It was used by Arthur Keith and Martin Flack as a detailed guide in their attempts to verify the existence of the Bundle of His, which subsequently led to their discovery of the sinoatrial node. Throughout the beginning of the 20th century, Tawara's monograph influenced the work of many cardiologists and it was later cited by Willem Einthoven in his anatomical interpretation of the electrocardiogram. Background Prior to Tawara's discoveries, it was assumed that electrical conduction through the Bundle of His was slow, because of the long interval between atrial and ventricular contractions.

Bundle Of His
The bundle of His (BH) or His bundle (HB) ( "hiss"Medical Terminology for Health Professions, Spiral bound Version'. Cengage Learning; 2016. . pp. 129–.) is a collection of heart muscle cells specialized for electrical conduction. As part of the electrical conduction system of the heart, it transmits the electrical impulses from the atrioventricular node (located between the atria and the ventricles) to the point of the apex of the fascicular branches via the bundle branches. The fascicular branches then lead to the Purkinje fibers, which provide electrical conduction to the ventricles, causing the cardiac muscle of the ventricles to contract at a paced interval. Function The bundle of His is an important part of the electrical conduction system of the heart, as it transmits impulses from the atrioventricular node, located at the anterior-inferior end of the interatrial septum, to the ventricles of the heart. The bundle of His branches into the left and the right bundle br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fukuoka
is the sixth-largest city in Japan, the second-largest port city after Yokohama, and the capital city of Fukuoka Prefecture, Japan. The city is built along the shores of Hakata Bay, and has been a center of international commerce since ancient times. The area has long been considered the gateway to the country, as it is the nearest point among Japan's main islands to the Asian mainland. Although humans occupied the area since the Jomon period, some of the earliest settlers of the Yayoi period arrived in the Fukuoka area. The city rose to prominence during the Yamato period. Because of the cross-cultural exposure, and the relatively great distance from the social and political centers of Kyoto, Osaka, and later, Edo (Tokyo), Fukuoka gained a distinctive local culture and dialect that has persisted to the present. Fukuoka is the most populous city on Kyūshū island, followed by Kitakyushu. It is the largest city and metropolitan area west of Keihanshin. The city was de ...
