A team of researchers at Karolinska Institutet has generated a map over the effects of small drug-like molecules on PARP1 and other similar proteins in the body. This map may explain the mechanism behind putative side effects of the so-called PARP inhibitors, and can play an important role in the development of novel tailor-made cancer drugs. The study is presented in the journal Nature Biotechnology, and will hopefully contribute to new cancer therapies with fewer detrimental side effects....

Fresh insights into how our cells multiply could help scientists develop drugs to treat cancer Fresh insights into how our cells multiply could help scientists develop drugs to treat cancer. Researchers have gained better understanding of the workings of two key proteins that control cell division. This process must be carried out accurately to keep cells healthy, and when it goes out of control, it can lead to cancer. The study, led by the University of Edinburgh, could contribute...

In “Mass Extinctions: Nature´s Spectacular Staging of Natural Selection” Julian Lieb, M.D  provides evidence that “die-offs” or mass deaths are episodes of natural selection, caused by activation of enzymes of the arachidonic acid cascade. In prior publications, Dr Lieb showed that products of the arachidonic acid cascade are the agents of natural selection and evolution, differentiating between infertility and reproduction, and between health and...

Rice University undergraduate simplifies tool for biomolecular research A Rice University undergraduate will depart with not only a degree but also a possible patent for his invention of an efficient way to create protein libraries, an important component of biomolecular research. Rice senior Manan Mehta discovered a method to create libraries of "circularly permuted" proteins at the suggestion of his mentor, bioengineer Jonathan Silberg. The research was reported this week in the...

Scientists have shed new light on the way superbugs such as MRSA are able to become resistant to treatment with antibiotics Scientists have shed new light on the way superbugs such as MRSA are able to become resistant to treatment with antibiotics. Researchers have mapped the complex molecular structure of an enzyme found in many bacteria. These molecules — known as restriction enzymes — control the speed at which bacteria can acquire resistance to drugs and eventually...

New research by scientists at the University of Southampton could lead to the design of more effective drugs to combat malaria. The research will enable scientists to learn more about the nature of the enzymes required for vitamin biosynthesis by the malaria causing pathogen Plasmodium. Vitamins are essential nutrients required in small amounts, the lack of which leads to deficiencies. Many pathogenic microorganisms produce vitamins, and these biosynthetic pathways may provide suitable...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
