In contrast, requires the traditional surgical approach, patients will be placed with a heart-lung machine stopped with their hearts, while a heart surgeon cuts maze-like patterns in the atrial tissue and sews the incisions the formation of lesions the formation of lesions or small scars. Surgeons can also alternative energy sources such as radiofrequency or cryothermy to create lesions in cardiac tissue. The lesions disrupt the abnormal electrical impulses AF AF.
Gallivan says, provide that the idea of bacteria this with caffeine, and give each bacterium a piece of DNA from coffee plants, the enzyme that allow the bacterium to the caffeine to theophylline it needs to survive can encode convert. Continue reading
The study examined ways to control the activity of phosphoenolpyruvate carboxykinase – a key enzyme in the metabolic pathway used by the human body to produce glucose involved. Phosphoenol helps to control blood sugar levels during fasting. An overproduction of this enzyme, among other events, may lead to type 2 diabetes.
The group examined the roles of three amino acid residues and, more specifically examined how the change of each residue affected the enzyme properties the researchers concluded that it is possible for the activity of the enzyme from a location other than where the. Reaction takes place, to influence on the enzyme. Continue reading
MRC scientists gain Royal Society Users MedalsTwo MRC – funded scientists have discovered a Royal Medal the Royal Society awarded. The annual awards are presented to scientists in recognition of the profound implications of their results for the other in their fields had have work done. Sir Alan Fersht, director of the MRC Centre for Protein Engineering, University of Cambridge, and Sir Philip Cohen, Director of the Medical Research Council Protein Phosphorylation Unit in Dundee are the medal winners.
Sir Alan Fersht FRS FMedSci , which was also the Herchel Smith Professor of Organic Chemistry at the University of Cambridge, with the Royal Medal of A for his pioneering work on protein engineering, which he developed into a fundamental tool of the enzyme analysis and the problem of protein folding.
