PrimPol allows cells to make copies of their DNA even when it is damaged, and prevents breaks in the chromosomes Every day, the human body produces new cells to regenerate tissues and repair those that have suffered injury. Each time this happens, the cells make copies of their DNA that they will pass on to the resulting daughter cells. This process of copying the DNA, also called replication, is very delicate, given that it can generate severe alterations in the DNA that are associated...

Combining common antibiotics with additional compounds could make previously resistant bacteria more susceptible to the same antibiotics. 'Resuscitation' of existing antibiotics has the potential to make infections caused by multidrug-resistant bacteria easier to control, reducing antibiotic usage and levels of antimicrobial resistance, say scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week. Researchers from University College...

Inhibiting the "drug efflux pumps" in bacteria, which function as their defence mechanisms against antibiotics, can mask the effect of mutations that have led to resistance in the form of low-affinity drug binding to target molecules in the cell. This is shown by researchers at Uppsala University in a new study that can provide clues to how the development of resistance to antibiotics in bacteria can be delayed.The introduction of antibiotics as drugs in the treatment of bacterial infections...

Green tea can help beat superbugs according to Egyptian scientists speaking today (Monday 31 March 2008) at the Society for General Microbiology's 162nd meeting being held this week at the Edinburgh International Conference Centre.The pharmacy researchers have shown that drinking green tea helps the action of important antibiotics in their fight against resistant superbugs, making them up to three times more effective.Green tea is a very common beverage in Egypt, and it is quite likely that...
