Both of these effects confirm and extend the result of other studies. The third result was that in people who exercised, the loss of white matter integrity caused by alcohol consumption was prevented or reduced, depending on how much exercise was done and which particular white matter tract in the brain is examined.
Penicillin is one of the earliest discovered and widely used antibiotic agents, derived from the Penicillium mold. Antibiotics are natural substances that are released by bacteria and fungi into the their environment, as a means of inhibiting other organisms-it is chemical warfare on a microscopic scale.
It is the mould that saved millions of lives by producing the first ever known modern antibiotic, the penicillin. The discovery of penicillin from the fungus Penicillium chrysogenum (then known as Penicillium notatum) by Sir Alexander Fleming in 1928, perfected the treatment of bacterial infections. The name Penicillium comes from the resemblance of the spore producing structures (conidiophores) of the fungus to a paintbrush (penicillus is the Latin word for paintbrush).
