|About me||SAN FRANCISCO Scarpe ECCO Slip On Italia , May 30 (Xinhua) -- A team of University of Washington (UW) synthetic biology researchers have demonstrated a new method for digital information processing in living cells, analogous to the logic gates used in electric circuits. Reported in the latest issue of Nature Communications, the researchers built a set of synthetic genes that function in cells like Negated OR gates, or NOR gates Scarpe ECCO Soft 7 Italia , commonly used in electronics, which each take two inputs and only pass on a positive signal if both inputs are negative. NOR gates are functionally complete, meaning one can assemble them in different arrangements to make any kind of information processing circuit. In the microchips that run electronic computers, information processing capabilities reduce data to zeros and ones. In living cells Scarpe ECCO Track 6 Italia , where constantly process information is taking place to keep track of the changing world around them and arrive at an appropriate response, deoxyribonucleic acid (DNA), proteins, lipids and sugars are arranged in complex and compartmentalized structures Scarpe ECCO Gtx Italia , as evolution has arrived at a mode of information processing at the cellular level. The potential of cells as living computers that can respond to disease, efficiently produce biofuels or develop plant-based chemicals is what researchers have been working on and searching for. The UW researchers built their circuits, the largest ever published to date in eurkaryotic cells, using DNA instead of silicon and solder Scarpe ECCO Toe Tie Italia , and inside yeast cells instead of at an electronics workbench. Eurkaryotic cells, like human cells, contain a nucleus and other structures that enable complex behaviors. Each cellular NOR gate consists of a gene with three programmable stretches of DNA -- two to act as inputs, and one to be the output. The researchers then took advantage of a relatively new technology known as clustered regularly interspaced short palindromic repeats associated protein 9 Scarpe Ecco Bianche Italia , or CRISPR-Cas9, to target those specific DNA sequences inside a cell. The Cas9 protein acts like a molecular gatekeeper in the circuit, sitting on the DNA and determining if a particular gate will be active or not. If a gate is active, it expresses a signal that directs the Cas9 to deactivate another gate within the circuit Scarpe Ecco Blu Italia , enabling the researchers to "wire" together the gates to create logical programs in the cell. What sets the new study apart from previous work, the researchers noted, is the scale and complexity of the circuits successfully assembled -- which included up to seven NOR gates assembled in series or parallel. At this size, circuits can begin to execute useful behaviors by taking in information from different environmental sensors and performing calculations to decide on the correct response. Imagined applications include engineered immune cells that can sense and respond to cancer markers or cellular biosensors that can easily diagnose infectious disease in patient tissue. Cells could potentially be reprogrammed to undergo new developmental pathways Scarpe Ecco Grigie Italia , to regrow organs or to develop entirely new ones. In such developing tissues, cells have to make complex digital decisions about what genes to express and when, and the new technology could be used to control that process. "While implementing simple programs in cells will never rival the speed or accuracy of computation in silicon, genetic programs can interact with the cell's environment directly Scarpe Ecco Marrone Italia ," senior author and UW electrical engineering professor Eric Klavins, was quoted as saying in a news release. "For example, reprogrammed cells in a patient could make targeted, therapeutic decisions in the most relevant tissues Ecco Sneakers Nere Italia , obviating the need for complex diagnostics and broad spectrum approaches to treatment."

As Bayern Munich last spring time started to entice Mats Hummels， the German head-coach knew about it and was asked about his opinion by Hummel's advisors. Loew not only understood Hummels desire to win big titles with a big club， but he saw at the same time the German national team would benefit just as much as Bayern Munich would. In both the club and national team， Hummels now plays alongside Jerome Boateng. Not only the easy 3-0 victory in the World Cup qualifier against the Czech Republic must have confirmed Loew was right to "support" the Hummels. This Tuesday evening the Hummels - Boateng duet is regarded to be a key to the succsess when the Germans face Northern Ireland in Hannover. For every national coach it must be a dream when his two central defenders play for the same club because it means the two know each almost like twins. In the case of Hummels and Boateng， the story continues as both are regarded to be among the top five central defenders in world football. To make it to the top for central defenders today means more than just defending. Hummels and Boateng's outstanding defending qualities stand for modern football as they are so called "game-opener"， meaning， they don't just kick the ball out of the danger zone but they are the first central defenders in Loew's team to have playmaker qualities. Football analysts have recently introduced a new method to show a player's effectivity. The so-called "packing" figure records how many oppo.
