Non-thermal plasma suppresses bacterial colonization on skin wound and promotes wound healing in mice.

The present study evaluated the effect of non-thermal plasma on skin wound healing in BalB/c mice. Two 6-mm wounds along the both sides of the spine were created on the back of each mouse (n=80) by using a punch biopsy. The mice were assigned randomly into two groups, with 40 animals in each group: a non-thermal plasma group in which the mice were treated with the non-thermal plasma; a control group in which the mice were left to heal naturally.

Evolution of HIV-1 in a patient population failing multiple-drug therapy.

To understand the evolutionary pathway of the multi-drug-resistant virus HIV-1 under drug-induced selection pressure, plasma from seven patients from baseline to different intervals post-treatment failure were used in RT-PCR protocols. Multiple clones were sequenced for each time point. Drug-resistant mutations were detected in five patients.
