Complex of bismuth, an anti-inflammatory drug, was studied by EPR spectroscopy. The aim of this study was to determine concentrations and properties of free radicals formed during thermal sterilization of bismuth subgallate according to pharmacopoeia norms to optimize its sterilization process. Different temperatures (160°C, 170°C, and 180°C) and times (120 minutes, 60 minutes, and 30 minutes) ...

BACKGROUND AND OBJECTIVES The safety and efficacy of female hysteroscopic sterilization using the Essure system has been well documented.

BACKGROUND Steam sterilization is an essential part of infection prevention. The literature shows that sterilization of medical instruments containing channels is not trivial. Phaco hand pieces have a simple configuration: a device contains a channel with a constant radius. No literature was found indicating whether the sterilization conditions on the inner surface of a phaco hand piece are inf...

Copper NiTi wires were introduced by Sachdeva R and Miyasaki S in 1994. This latest innovation in the evolutionary scale gives us the opportunity of choosing the force level by choosing the temperature at which the wires will deliver its optimum force level. With so many advantages and their ability to return to their original form coupled with the high cost of copper NiTi many clinicians start...

In the food industry field, heat sterilization, as a routine sterilization approach, is widely adopted. During such a process, the prepackaged foods in cans or pouches are put into a autoclave which is filled with the hot water or steam used as the medium of the thermal process. People can, under some particular requirements, have the appropriate control of the sterilization process by adjustin...

Tubal sterilization is one of the contraceptive methods whose use has increased the most in Brazil, but a growing number of women have expressed regret after the procedure. A case-control study was conducted at the Centro Integrado de Saúde Amaury de Medeiros (CISAM), Recife, Pernambuco, Brazil, in 1997 to investigate the association between changes in family structure and request for or submit...

Statement of the Problem File fracture can interfere with cleaning and shaping of the canal and compromise periradicular healing. Autoclave sterilization may prone the files to fracture. Purpose The purpose of the present study was to determine the effect of autoclave sterilization on the cyclic fatigue resistance of Hero642 rotary instrument in two curvatures of 45 and 60 degrees. Material...

To evaluate the possibilities of using gamma irradiation for the sterilization of ointments, the effect of irradiation on spores of Bacillus pumilus and Bacillus sphaericus in dry material and in two different kinds of ointments was studied. The results indicate that for sterilization purposes irradiation was less effective in white petrolatum as compared to irradiation in the dry state. No suc...
