Introduction: Early childhood caries (ECC) is one of the most common problems in children worldwide which is seen in 3-45% preschool children population. Bacterial factor is one of the main four components (time, microorganism, diet, host) to create caries. Streptococcus mutans is one of the most important cariogenic microorganisms. The objective of this study is evaluating Streptococcus mutans...
Sibling Paenibacillus dendritiformis bacterial colonies grown on low-nutrient agar medium mutually inhibit growth through secretion of a lethal factor. Analysis of secretions reveals the presence of subtilisin (a protease) and a 12 kDa protein, termed sibling lethal factor (Slf). Purified subtilisin promotes the growth and expansion of P. dendritiformis colonies, whereas Slf is lethal and lyses...
purpose: to determine bacterial flora of the conjunctiva and lacrimal sac in adult patients with naso-lacrimal duct obstruction (nldo) in comparison with normal flora. methods: this study included 40 consecutive adult patients with nldo and 40 age- and sex matched healthy controls. specimens for bacterial culture were obtained from the involved and normal conjunc-tiva preoperatively and from th...
The cDNAs encoding three germin-like proteins (PsGER1, PsGER2a, and PsGER2b) were isolated from Pisum sativum. The coding sequence of PsGER1 transiently expressed in tobacco leaves gave a protein with superoxide dismutase activity but no detectable oxalate oxidase activity according to in-gel activity stains. The transient expression of wheat germin gf-2.8 oxalate oxidase showed oxalate oxidase...
Abstract Background: Dental caries are one of the major clinical problems. Bacterial treatment is an alternative technique for pathogen microorganism replacement. The most common bacterial treatment technique is using probiotic bacteria. The aim of this study was to evaluate short-term consumption of probiotic yogurt on salivary Streptococcus mutans and Lactobacillus in adult. Materials and met...
Self organized systems have been widely studied during the past decades. The definition of a concrete collective behavior in a population and the interaction between the individuals is known as swarm intelligence (SI). By observing natural conducts, some SI models that are very popular nowadays have been developed recently like Ant Colony Optimization or Artificial Bee Colony algorithms. The ai...
