Antioxidant activity of lactic acid bacteria is associated with multiple health-protective effects. Traditional indexes of chemical antioxidant activities poorly reflect the antioxidant effects of these bacteria in vivo. Cellular antioxidant activity (CAA) assay was used in this study to determine the antioxidant activity of cell-free supernatants (CFSs) of 10 Lactobacillus strains. The perform...

OBJECTIVE To assess the level of fear of dental procedures among 6-12 year school children and correlate the prevalence of dental caries with their dental fears scores. MATERIALS AND METHODS The study sample of 444 school children, comprising of 224 girls and 220 boys in the age group of 6-12 years old from a private English medium school were selected. Each student was asked to independently...

BACKGROUND The aim of this study was to provide insight on dental fear amongst schoolchildren and evaluate the association between caries experience and fear of dental procedures. METHODS A sample size of 250 students (both sexes) of ages 10-14 years were enrolled in the study. Before dental examination, each participant was informed about the study and given the Children's Fear Survey Schedu...

Fragile sites are loci of recurrent chromosome breakage in the genome. They are found in organisms ranging from bacteria to humans and are implicated in genome instability, evolution, and cancer. In budding yeast, inactivation of Mec1, a homolog of mammalian ATR, leads to chromosome breakage at fragile sites referred to as replication slow zones (RSZs). RSZs are proposed to be homologous to mam...

Aim: Antibiotic resistance is a major health problem. Recently, probiotics are used in the field of alternative/supportive medicine. Thus, this study, we aimed to evaluate vitro inhibitory effects four different cell-free supernatants (CFSs) lactobacilli species (L. fermentum, L. plantarum, acidophilus and rhamnosus) on clinically isolated Methicilin-resistant Staphylococcus aureus (MRSA) strai...

BACKGROUND Dental fear (DF) is a challenging problem in dentistry. It is multifactorial in origin and many contributing factors have been identified. The aim of the study was to assess dental fear among 12-15 years old Arabic speaking children in Jeddah, Saudi Arabia and its relation to demographic variables, previous dental experience, and child behaviour. METHODS In this cross-sectional stu...

Objective: Free-living amoeba (FLA) are protozoa living in soil and natural man-made water systems. They attract much attention owing to the illnesses associated with them their relationships bacteria. In this study, effect of cell-free supernatant (CFS) obtained from FLA against Staphylococcus was investigated. Materials Methods: Environmental strains (A1, A2, A3) were lake swimming pools Ista...

The earthquake (ML5.2) which occurred at Chushan town, Nantou on Nov.11, 2017 resulted many aftershocks around the hypocenter of mainshock. coulomb stress changes (∆CFSs) by mainshock demonstrated most located within portions with ∆CFSs greater than 0.1 bar, revealing may be induced After investigating different depths, results showed positive values under depth 15km were transferred...

Aim: This study compared the levels of dental anxiety experienced by young uncooperative children having dental rehabilitation using general anaesthesia (GA) with those who had their dental treatments by “Tell-ShowDo” technique in the dental clinic. Methods: Out of 54 children, 26 had been treated under GA and 28 had been treated with the use of “Tell-Show-Do” behavioural approach method. At th...
