Wilson Teixeira Beraldo
Wilson Teixeira Beraldo (20 April 1917, Silvianópolis, state of Minas Gerais, Brazil – 28 July 1998, Belo Horizonte, Minas Gerais) was a Brazilian physician and physiologist, a co-discoverer of bradykinin. Beraldo graduated in medicine in 1942, having studied at the Federal University of Minas Gerais. He was also associate professor of physiology of the Faculty of Medicine of the University of São Paulo, and full professor and chairman of physiology of the Faculty of Medicine of the Federal University of Minas Gerais (1962). Beraldo was also a fellow of the Rockefeller Foundation (1949) and of the British Council (1954), a member of the New York Academy of Sciences and of the Academia Brasileira de Ciências, Brazilian Academy of Sciences. As a scientific leader, Beraldo was very important for the development of physiology in Brazil, and of the scientific establishment in general. He was a founding member of the Sociedade Brasileira para o Progresso da Ciência, Brazilian Ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Instituto Biológico
Biological Institute (''Instituto Biológico'' in Portuguese) is an applied research center organised in 1924 in São Paulo, Brazil. It is a governmental organisation concerned with the prevention of zoonoses and foodborne animal pathogens such as rabies and tuberculosis, sanitary advertisement campaigns, alternatives to the chemical control of diseases such as organic farming and biological control. Among its main achievements are the biological control of the coffee borer beetle in the 1920s in Brazil, the discovery of bradykinin, and the production of vaccines that combat the Newcastle disease, foot-and-mouth disease and the black plague in pigs. History Brazil used to be an important world coffee supplier in the international commodities markets in the beginning of the 20th century. Especially in the state of São Paulo, coffee became a major source of income from exports, and newly-rich coffee barons were sprouting all over the state. In the early 1920s, coffee farmers in t ...

Academic Staff Of The University Of São Paulo
An academy ( Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, '' Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kinin
A kinin is any of various structurally related polypeptides, such as bradykinin and kallidin. They are members of the autacoid family. Kinins are peptides that are cleaved from kininogens by the process of kallikreins. Kallikreins activate kinins when stimulated. It is a component of the kinin-kallikrein system. Their precursors are kininogens. Kininogens contain a 9-11 amino acid bradykinin sequence. In botany, the plant hormones known as cytokinins were first called kinins, but the name was changed to avoid confusion. Effects of Kinins Kinin are short lived peptides that cause pain sensation, arteriolar dilation, increase vascular permeability and cause contractions in smooth muscle. Kinins transmit their effects through G protein- coupled receptors. Kinin act on axons to block nervous impulses, which leads to distal muscle relaxation. Kinin are also potent nerve stimulators. which is mostly responsible for the sense of pain (and sometimes itching). Kinin increase vascular ...

Oxytocin
Oxytocin (Oxt or OT) is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. It plays a role in social bonding, reproduction, childbirth, and the period after childbirth. Oxytocin is released into the bloodstream as a hormone in response to sexual activity and during labour. It is also available in pharmaceutical form. In either form, oxytocin stimulates uterine contractions to speed up the process of childbirth. In its natural form, it also plays a role in bonding with the baby and milk production. Production and secretion of oxytocin is controlled by a positive feedback mechanism, where its initial release stimulates production and release of further oxytocin. For example, when oxytocin is released during a contraction of the uterus at the start of childbirth, this stimulates production and release of more oxytocin and an increase in the intensity and frequency of contractions. This process compounds in inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pancreas
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e. it has both an endocrine and a digestive exocrine function. 99% of the pancreas is exocrine and 1% is endocrine. As an endocrine gland, it functions mostly to regulate blood sugar levels, secreting the hormones insulin, glucagon, somatostatin, and pancreatic polypeptide. As a part of the digestive system, it functions as an exocrine gland secreting pancreatic juice into the duodenum through the pancreatic duct. This juice contains bicarbonate, which neutralizes acid entering the duodenum from the stomach; and digestive enzymes, which break down carbohydrates, proteins, and fats in food entering the duodenum from the stomach. Inflammation of the pancreas is known as pancreatitis, with common causes including chronic alcohol use and gallstones. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kidney
The kidneys are two reddish-brown bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder. The kidney participates in the control of the volume of various body fluids, fluid osmolality, acid–base balance, various electrolyte concentrations, and removal of toxins. Filtration occurs in the glomerulus: one-fifth of the blood volume that enters the kidneys is filtered. Examples of substances reabsorbed are solute-free water, sodium, bicarbonate, glucose, and amino acids. Examples of substances secreted are hydrogen, ammonium, potassium and uric acid. The nephron is the structural and functional unit of the kidney. Each adult human kidney contains around 1 million nephrons, while a mouse kidney con ...

Bothrops Jararaca
''Bothrops jararaca'' — known as the ''jararaca'' or ''yarara'' — is a highly venomous pit viper species endemic to South America in southern Brazil, Paraguay, and northern Argentina. The specific name, ''jararaca'', is derived from the Tupi words and , which mean "large snake". Within its geographic range, it is often abundant and is an important cause of snakebite. No subspecies are currently recognized. The drugs known as angiotensin converting enzyme (ACE) inhibitors, used for the treatment of hypertension and some types of congestive heart failure, were developed from a peptide found in the venom of this species. Description This is a slender and terrestrial species that grows to a maximum total length of 160 cm (63 in), although the average total length is much less. The head scalation includes 5-12 intersupraoculars that are weakly keeled, 7-9 supralabials (usually 8) of which the second is fused with the prelacunal to form a lacunolabial, and 9-13 sub ...
