Aesthetics of teeth, including tooth color, is of great importance to people. Conventional clinical tooth-whitening treatments are mainly based on hydrogen peroxide (H2O2), while some studies demonstrate that the bleaching process can be accelerated when enhanced by heat or light (laser, cold light). The dependence on H2O2 may lead to sensitivity or different degree of injury on soft tissue. As the...
Oral squamous cell carcinoma (OSCC) is the most widespread malignant oral cavity neoplasm, with even higher proportion of deaths than breast cancer and cervical cancer. Although advances were made in conventional treatment for OSCC such as surgery and radiation therapy, there has not been significant increase in the 5-year survival rate in the past four decades, and chemotherapeutic drug resistance...
In our previous studies, we have found that during atmospheric pressure cold plasma treatment, oxidative stress pathways are required for yeast cell response. In addition, overexpressions of anti-oxidant SOD genes can remarkably protective yeast cells from plasma injury. These results are in coincidence with other groups' findings with mammalian cells, thus encouraging us to explore more on the anti-oxidative...
A direct current atmospheric pressure cold plasma jet was used to inactivate Staphylococcus aureus (S. aureus) suspended in a liquid. Three types of gases, pure argon (99.999%), argon with 2% oxygen, and argon with 2% oxygen and 10% nitrogen were used as operating gases respectively. The inactivation efficacies for the plasma jets operating in the three gases decrease from Ar/O2(2%) to Ar/O2(2%)/N2(10%)...
Summary form only given. Dermatophytes are the most common aetiological agents, which invade into keratinized tissues (skin, hair, nails) of humans and animals causing dermatophytosis (also known as ringworm or tinea). Swimming pools, fitness centers, barber shops, beauty parlors, saunas and steam baths are common places to pick up superficial fungal infections. Mycotic infections have become more...
Summary form only given. Eating habits, smoking, drugs and chemicals can cause undesirable staining of teeth. Tooth bleaching has become a popular dental practice to remove stains from the tooth surface for aesthetic or therapeutic purposes. Clinical teeth-whitening involves the application of H2O2 gel (35%), which might be harmful after prolonged use.In this paper, we present tooth-whitening results...
Summary form only given. Aqueous environments are susceptible to contamination by bacteria, protozoa and viruses, which are the root cause of various illnesses. These contaminations are usually treated by chemical methods. Recently, attempts have been made to inactivate bacteria in water with non-thermal plasmas using various approaches, e.g., a pulsed streamer discharge plasma or a gliding arc discharge...
