Hilda Cid
Hilda Cid Araneda (born 20 February 1933) is a Chilean scientist who excelled in the field of crystallography. She was the first Chilean female to complete a PhD in Exact Sciences. She made remarkable contributions both as a professor of mathematics and physics and as influential researcher on structural biology, specially in protein crystallography. Life and career Hilda Cid Araneda was born on 20 February 1933 in the port city of Talcahuano (Chile), where she completed her primary and secondary studies. She was the daughter of two school teachers, well aware of the importance of the education of their children. In 1951, Hilda enrolled in the Teacher's career in physics and mathematics at the University of Concepción and in 1955 won the university prize awarded to the best undergraduate student. She moved then to the Pedagogical Institute of the University of Chile in Santiago (Chile), where she joined the laboratory of crystallography and did some research in physics while ...

Austral University Of Chile
Austral University of Chile ( or UACh) is a Chilean research university based primarily in Valdivia, with satellite campuses in Puerto Montt and Coyhaique. Founded on September 7, 1954, it is one of the eight original Chilean Traditional Universities. It operates as a nonprofit self-owned corporation under private law, and receives significant state-funding. History Foundation and early years (1942–1968) In 1942, the ''Sociedad de Amigos del Arte (Society of friends of art)'' was formed in the city of Valdivia. Aside from promoting culture, one of the society's main goals was to establish a university in the city. The idea of creating a university was presented to the national congress in the 1950s by the senator for Valdivia, Carlos Acharán Pérez de Arce, who later succeeded in consolidating the project. In a meeting held on 16 February 1954 supporters of installing a university created a directory and proclaimed Eduardo Morales Miranda as president of it. The initial ...

Structural Biologists
A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as organism, biological organisms, minerals and chemical substance, chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a Complex network, network featuring many-to-many Link (geometry), links, or a lattice (order), lattice featuring connections between components that are neighbors in space. Load-bearing Buildings, aircraft, skeletons, Ant colony, anthills, beaver dams, bridges and salt domes are all examples of Structural load, load-bearing structures. The results of construction are divided into buildings and nonbuilding structure, non-building structures, and make up the infrastructure of a human society. Built str ...

Deoxyribonuclease I
Deoxyribonuclease I (usually called DNase I), is an endonuclease of the DNase family coded by the human gene DNASE1. DNase I is a nuclease that cleaves DNA preferentially at phosphodiester linkages adjacent to a pyrimidine nucleotide, yielding 5'-phosphate-terminated polynucleotides with a free hydroxyl group on position 3', on average producing tetranucleotides. It acts on single-stranded DNA, double-stranded DNA, and chromatin. In addition to its role as a waste-management endonuclease, it has been suggested to be one of the deoxyribonucleases responsible for DNA fragmentation during apoptosis. DNase I binds to the cytoskeletal protein actin. It binds actin monomers with very high (sub-nanomolar) affinity and actin polymers with lower affinity. The function of this interaction is unclear. However, since actin-bound DNase I is enzymatically inactive, the DNase-actin complex might be a storage form of DNase I that prevents damage of the genetic information. This protein is stored ...

Actin
Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils. It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 nm. An actin protein is the monomeric subunit of two types of filaments in cells: microfilaments, one of the three major components of the cytoskeleton, and thin filaments, part of the contractile apparatus in muscle cells. It can be present as either a free monomer called G-actin (globular) or as part of a linear polymer microfilament called F-actin (filamentous), both of which are essential for such important cellular functions as the mobility and contraction of cells during cell division. Actin participates in many important cellular processes, including muscle contraction, cell motility, cell division and cytokinesis, vesicle and organelle mov ...

Carbonic Anhydrase
The carbonic anhydrases (or carbonate dehydratases) () form a family of enzymes that catalyst, catalyze the interconversion between carbon dioxide and water and the Dissociation (chemistry), dissociated ions of carbonic acid (i.e. bicarbonate and hydrogen ions). The active site of most carbonic anhydrases contains a zinc ion. They are therefore classified as metalloprotein, metalloenzymes. The enzyme maintains Acid–base homeostasis, acid-base balance and helps transport carbon dioxide. Carbonic anhydrase helps maintain acid–base homeostasis, regulate pH, and fluid balance. Depending on its location, the role of the enzyme changes slightly. For example, carbonic anhydrase produces acid in the stomach lining. In the kidney, the control of bicarbonate ions influences the water content of the cell. The control of bicarbonate ions also influences the water content in the eyes. Inhibitors of carbonic anhydrase are used to treat glaucoma, the excessive build-up of water in the eyes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uppsala University
Uppsala University (UU) () is a public university, public research university in Uppsala, Sweden. Founded in 1477, it is the List of universities in Sweden, oldest university in Sweden and the Nordic countries still in operation. Initially founded in the 15th century, the university rose to significance during the rise of Swedish Empire, Sweden as a great power at the end of the 16th century and was then given relative financial stability with a large donation from Monarchy of Sweden, King Gustavus Adolphus of Sweden, Gustavus Adolphus in the early 17th century. Uppsala also has an important historical place in Swedish national culture, and national identity, identity for the Swedish establishment: in historiography, religion, literature, politics, and music. Many aspects of Swedish academic culture in general, such as the white student cap, originated in Uppsala. It shares some peculiarities, such as the student nation system, with Lund University and the University of Helsink ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
