The treatment of locoregional recurrence (LRR) of head and neck squamous cell carcinoma (HNSCC) often requires a combination of surgery, radiation therapy and/or chemotherapy. Survival outcomes are poor and the treatment outcomes are morbid. Cold atmospheric plasma (CAP) is an ionized gas produced at room temperature under laboratory conditions. We have previously demonstrated that treatment wi...

F OUR trials were conducted with boar spermatozoa to determine the effects of dilution rate, seminal plasma content and extender composition on susceptibility to cold shock and the development of resistance to cold during 30 C incubation. Acrosome morphology and sperm motility were used to assess damage by cold shock. The susceptibility of boar spermatozoa to cold shock increased as the dilutio...

Effects of cold oxygen plasma treatment on activating the surface of poplar veneers and improving its wettability were investigated. The veneers were treated with cold oxygen plasma for 1, 3, 5, 7, and 9 min, and aged in air for 1, 3, 7, 14, 21, and 28 days. The dynamic adhesive wettability of veneers was assessed using the contact angle, K-value analysis, and surface free energy. The shear str...

Non-thermal atmospheric pressure ('cold') plasmas have received increased attention in recent years due to their significant biomedical potential. The reactions of cold plasma with the surrounding atmosphere yield a variety of reactive species, which can define its effectiveness. While efficient development of cold plasma therapy requires kinetic models, model benchmarking needs empirical data....

Th is study investigated the potential eff ect of cold plasma on reducing residues of pesticides diazinon and chlorpyrifos in apples and cucumbers and its eff ects on property of products. Two separate concentrations of each pesticide with 500 and 1,000 ppm were prepared and the samples were inoculated by dipping them into the solutions. All samples treated with pesticides were exposed to cold ...

Cold plasma is increasingly under research for decontamination of foods, especially fresh fruits and vegetables. The effect of cold plasma on food quality, however, remains under researched. This study investigates the effects of cold plasma generated within a sealed package from a dielectric barrier discharge on the physical quality parameters and respiration rates of cherry tomatoes. Respirat...

The nano-modification of selected substrates by means of atmospheric cold plasma treatment was exploited for the two-dimensional (2D) self-assembling of silver nanoparticles (Ag NPs). Such a useful combination of the cold plasma treatment of substrate surface and an immediate easy deposition of Ag NPs creating the 2D self-assemblies on the substrates is published for the first time, to the best...

This review explores the use of microwave heating and microwave-generated plasma for biosecurity applications. Microwave has been shown to rapidly heat kill a wide range pests pathogens. Examples thermal disinfestation soils, grains, hay, timber are presented discussed. energy can also ionize various gasses, including air, create plasma. Plasmas described by many characteristics, such as temper...

two hundred and fifty day-old broiler chickens were housed in a high altitude farm and divided in two experimental groups (cold-exposed and control). at the age of 3 and 4 d, the cold-exposed chickens were exposed to 15?c for 3 h, while the control birds were reared under normal condition. during the period between 14 and 28 days, both groups of chickens were exposed to a low environmental temp...

BACKGROUND Cold atmospheric plasma could constitute an alternative against multi-drug resistant pathogens. Susceptibility of enterococci to cold atmospheric plasma was investigated in vitro. METHODS 39 clinical isolates of enterococci were grouped dependent on the most important resistance patterns and treated on agar using dielectric barrier discharge plasma. These included enterococci with ...
