search for novel antimicrobial agents from microorganisms, an actinomycete strain Streptomyces sp. isolated from a soil sample collected in Taejon, Korea, was found to produce a new antibacterial 16-methyloxazolomycin (1). In this paper, we describe the production, isolation, structural elucidation and biological activities of 1. The strain was cultured in the seed mediumconsisting of glucose 2...

OBJECTIVE: To determine the optimal radiation dose and observe the influence of radiation sterilization on spirulina polypeptide powder. METHODS: The polypeptide powder of spirulina was sterilized using a 60Coγ ray. RESULTS: Radiation sterilization had significant effects on spirulina polypeptide powder, which was more effective with increasing radiation dose. Taking the sterilization rate and ...

Sterilization: The world’s most widely used method Sterilization is the world’s most widely used contraceptive method, in developing and developed countries alike. It accounts for nearly half of all contraceptive use. Today, one out of four couples worldwide use sterilization as their family planning method. However, the number of female sterilization users exceeds the number of vasectomy users...

Women who undergo sterilization may later regret this decision. This systematic review examines whether age at sterilization is associated with poststerilization regret. Using MEDLINE and EMBASE, we identified 19 articles that examined associations between women's age at sterilization and later regret, requests for sterilization reversal and undergoing sterilization reversal or requesting in vi...

The development of bio-resorbable implant materials is rapidly going on. Sterilization of those materials is inevitable to assure the hygienic requirements for critical medical devices according to the medical device directive (MDD, 93/42/EG). Biopolymer-containing biomaterials are often highly sensitive towards classical sterilization procedures like steam, ethylene oxide treatment or gamma ir...

Sterilization is a process that eliminates or kills all microbes, including transmissible agents present on a surface, contained in a fluid, medication or biological culture media (UCLA Department Epidemiology). Dry heat sterilization is one of the important methods of eliminating microbes, as it coagulates the proteins in an organism, causing oxidative free radical damage thus leading to cell ...
