Influence of the flexural modulus of prefabricated and experimental posts on the fracture strength and failure mode of composite resin cores.

The purpose of this study was to evaluate the influence of flexural modulus of non-metal posts on the fracture strength and failure mode of composite resin cores. Thirty-two human premolars were divided into four groups: prefabricated glass fiber post with 1.0 mm diameter and composite resin core (Group PE1.

The effect of feeding lactic acid to Salmonella typhimurium experimentally infected swine.

Antimicrobial resistant Salmonella are becoming more prevalent. Therefore, alternative methods to control swine Salmonella infection must be explored. We examined whether feeding lactic acid to swine is an effective way to control clinical and subclinical Salmonella Typhimurium infection in these animals.
