Raymond C. Stevens
Raymond C. Stevens (born 1963) is an American chemist and Structural biology, structural biologist, Founder, CEO and Board Member of Structure Therapeutics; Founding Director of the at ShanghaiTech University; Professor Emeritus of Chemistry, and Founding Director of the Bridge Institute at the University of Southern California; Board Member, Danaher Corporation.

However, an enthusiastic professor (John Ricci) converted him to the study of Chemistry. He s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structural Biology
Structural biology is a field that is many centuries old which, and as defined by the Journal of Structural Biology, deals with structural analysis of living material (formed, composed of, and/or maintained and refined by living cells) at every level of organization. Early structural biologists throughout the 19th and early 20th centuries were primarily only able to study structures to the limit of the naked eye's visual acuity and through magnifying glasses and light microscopes. In the 20th century, a variety of experimental techniques were developed to examine the 3D structures of biological molecules. The most prominent techniques are X-ray crystallography, nuclear magnetic resonance, and electron microscopy. Through the discovery of X-rays and its applications to protein crystals, structural biology was revolutionized, as now scientists could obtain the three-dimensional structures of biological molecules in atomic detail. Likewise, NMR spectroscopy allowed information about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Southgate Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow the Oxfor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

G Protein-coupled Receptor
G protein-coupled receptors (GPCRs), also known as seven-(pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptors, and G protein-linked receptors (GPLR), form a large group of evolutionarily-related proteins that are cell surface receptors that detect molecules outside the cell and activate cellular responses. Coupling with G proteins, they are called seven-transmembrane receptors because they pass through the cell membrane seven times. Text was copied from this source, which is available under Attribution 2.5 Generic (CC BY 2.5) license. Ligands can bind either to extracellular N-terminus and loops (e.g. glutamate receptors) or to the binding site within transmembrane helices (Rhodopsin-like family). They are all activated by agonists although a spontaneous auto-activation of an empty receptor can also be observed. G protein-coupled receptors are found only in eukaryotes, including yeast, choanoflagellates, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of California, Berkeley
The University of California, Berkeley (UC Berkeley, Berkeley, Cal, or California) is a public land-grant research university in Berkeley, California. Established in 1868 as the University of California, it is the state's first land-grant university and the founding campus of the University of California system. Its fourteen colleges and schools offer over 350 degree programs and enroll some 31,800 undergraduate and 13,200 graduate students. Berkeley ranks among the world's top universities.

Tenure-track
Tenure is a category of academic appointment existing in some countries. A tenured post is an indefinite academic appointment that can be terminated only for cause or under extraordinary circumstances, such as financial exigency or program discontinuation. Tenure is a means of defending the principle of academic freedom, which holds that it is beneficial for society in the long run if scholars are free to hold and examine a variety of views. By country United States and Canada Under the tenure systems adopted by many universities and colleges in the United States and Canada, some faculty positions have tenure and some do not. Typical systems (such as the widely adopted "1940 Statement of Principles on Academic Freedom and Tenure" of the American Association of University Professors) allow only a limited period to establish a record of published research, ability to attract grant funding, academic visibility, teaching excellence, and administrative or community service.

Aspartate Carbamoyltransferase
Aspartate carbamoyltransferase (also known as aspartate transcarbamoylase or ATCase) catalyzes the first step in the pyrimidine biosynthetic pathway (). In ''E. coli'', the enzyme is a multi- subunit protein complex composed of 12 subunits (300 kDa in total). The composition of the subunits is C6R6, forming 2 trimers of catalytic subunits (34 kDa) and 3 dimers of regulatory subunits (17 kDa). The particular arrangement of catalytic and regulatory subunits in this enzyme affords the complex with strongly allosteric behaviour with respect to its substrates. The enzyme is an archetypal example of allosteric modulation of fine control of metabolic enzyme reactions. ATCase does not follow Michaelis–Menten kinetics. Instead, it lies between its low-activity, low-affinity "tense" and its high-activity, high-affinity "relaxed" states. The binding of substrate to the catalytic subunits results in an equilibrium shift towards the R state, whereas binding of CTP to the regulatory subu ...

Marathon Des Sables
''Marathon des Sables'', or MdS, ( French for Marathon of the Sands, also known as Sahara Marathon) "Facing Africa NOMA : The Marathon des Sables", FacingAfrica.org, 2010, webpage: -->pages/mds/default.asp FA8. is a six-day, ultramarathon, which is approximately the distance of six regular marathons. The longest single stage (2009) is long. This multiday race is held every year in southern Morocco, in the Sahara Desert. It has been regarded as the toughest foot race on Earth. The first event of the Marathon started in 1986. History The marathon was the brainchild of French concert promoter Patrick Bauer who in 1984 traversed the Sahara desert on foot and alone. He covered 350 km (214 mi) in 12 days without encountering a single oasis or desert community along the way. Two years later in 1986 the first ''Marathon des Sables'' was run. Twenty-three runners participated in the race with Bernard Gaudin and Christiane Plumere, both of France, finishing as th ...

American River 50 Mile Endurance Run
The American River 50 Mile Endurance Run, or AR50, is the second largest 50-mile (80.47 kilometer) ultramarathon beginning in Sacramento, California and ending in Auburn, California. The event is held annually in April. For most of the first , the course follows a bike path that runs along the American River, then switches to trails for the remainder of the race. Awards In addition to 1st, 2nd, and 3rd place awards in each age division, all runners who cross the finish line in less than 14 hours are awarded a special finisher's jacket. Also, the Dick Collins Legend Award is presented at the finish of the AR50. History The race was first held in 1980 with 200 participants. For its first two years, the starting line was in Auburn and runners finished in Sacramento. In 1982, this was reversed and the race has started in Sacramento. The 2010 race was won by Geoff Roes and Tracy Garneau. Records The course record for the Sacramento to Auburn run for men was set in 1994 by Tom ...
