Axenic (germfree) and holoxenic (conventional) rats were given a pectincontaining diet (5 %1 or a pectin-free diet. The diet was not sterilized and the axenic state was maintained by the addition of antibiotics. Pectin modified little or not at all the quantity of bile acids in the small intestine, fecal bile acid excretion and fecal elimination of the sum of cholesterol and bile acids. It simi...

Impressions, dentures and other dental appliances may be contaminated with oral micro-flora or other organisms of varying pathogenicity from patient's saliva and blood. Several approaches have been tried to control the transmission of infectious organisms via dental impressions and because disinfection is less effective and has several drawbacks for impression characterization, several steriliz...

Micropropagation of banana (Musa paradisiaca Linn.) var Grand naine was carried out with media sterilized by microwave radiation. Microwave oven was effectively used to sterilize the media for in vitro shoot-multiplication of banana against autoclave. Sterilization of media in microwave oven was successfully achieved at 900W/200 ml media (4 min). In vitro shoot-multiplication was higher in the ...

Various local drug delivery devices and coatings are being developed as slow, sustained release mechanism for drugs, yet the polymers are typically not evaluated after commercial sterilization techniques. We examine the effect that commercial sterilization techniques have on the physical, mechanical, and drug delivery properties of polyurethane polymers. Specifically we tested cyclodextrin-hexa...
