The number, size, distribution, and variety of resulting colonies were noted. To test whether these bacteria could have come from oral sources, 17 colonies were selected for culture on Mitis-Salivarius (M-S) agar. Those colonies that grew on the M-S agar were Gram stained.
Results. Twenty-eight test plates (56%) exhibited growth of
bacterial colonies on blood agar. Seventeen of those bacterial colonies were selected for growth on M-S agar, and 13 (76.47%) showed growth, 69% of them gram positive.
Conclusion. Our results indicate reinforcing standard precautions of infection control for intraoral radiography, and that gas sterilization of plates after each day’s clinical use is a potential PARP signaling solution. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010; 109: 457-462)”
“We present a detailed study of strain behavior associated with martensitic transition in polycrystalline Ni45Co5Mn37In13 Heusler alloy. A spontaneous phase transition strain with the value of about 0.4% in this alloy can be acquired by applying and removing Selleckchem MK2206 magnetic field, exhibiting a large two-way metamagnetic shape memory effect (MSME) with nonprestrain. This effect is originated from magnetoelastic coupling due to a large difference in Zeeman energy between austenitic
and martensitic phases. In addition, it was also found that even after three magnetic field cycles at 320 K, the two-way MSME is still reproducible. Such characteristic could be ascribed to a random orientation of martensite variants in present alloy. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3516487]“
“A novel processing method of combining dynamic vulcanization with the silane-grafted water-crosslinking technique to improve the comprehensive
properties of polyethylene (PE) is reported. PE was grafted with vinyl triethoxysilane (VTEO) first, and then, N,N,N’,N’-tetragylcidyl-4,4′-diaminodiphenylmethane epoxy resin was dynamically cured in a PE-g-VTEO matrix through a twin-screw extruder to prepare PE-g-VTEO/epoxy blends. Polyethylene-graft-maleic selleck chemicals llc anhydride (PE-g-MAH) was used as a compatibilizer to improve the interaction between PE-g-VTEO and the epoxy resin. The results show that the novel processing method improved the strength, stiffness, and toughness of the blends, especially the heat resistance of the blends, by the addition of the dynamically cured epoxy resin as the reinforcement. PE-g-MAH increased the compatibility between PE-g-VTEO and the epoxy resin, which played an important role in the improvement of the comprehensive properties of the blends. In addition, after treatments in both hot air and hot water, the comprehensive properties of blends were further improved, thanks to the further curing reaction of epoxy with PE-g-VTEO.
