introduction: coronal microleakage is the major cause of failure of root canal treatments. the purpose of this study was to evaluate the sealing ability of white mta, c&b; metabond and cavit against coronal microleakage of enterococcus faecalis for four months. methods and materials: ninety extracted single–rooted human teeth were selected. root canal instrument-tation and abturation with gutta...

To investigate the effects of carvacrol supplementation in rainbow trout induced by lipopolysaccharide (LPS), relative gene expressions levels of some pro-inflammatory cytokines and apoptosis markers in kidney and liver were measured. Fish with a mean weight of 44.71±1.33 g were studied using four different treatments with three replicates each. Inflammation and apoptosis were performed using L...

The study investigated the effect of 10% aqueous extracts ginger, garlic and onion on quality shelf life frozen chevon pork as reflected by changes in values 2-thiobartituric acid reactive substances (2-TBARS) total volatile basic nitrogen (TVB-N) over a 14 day storage under conditions.  pH, 2-TBARS TVB-N were measured from at -20°C after days. resulted low pH 5.63, 5.79 5.67 for mixed...

The following chemical changes were observed during the cold storage of mussels for 6 days at 4 ◦C. Total volatile basic nitrogen (TVB-N, mg N per 100 g) and trimethylamine values (TMA-N, mg N per 100 g) were increased from 22.55 and 5.96 mg per 100 g at day 0 to 12.38 and 0.42 mg per 100 g, respectively, at the end of the storage period. The indole value and putrescine concentration were incre...

nowadays, using natural preservatives than synthetic ones is increasing. the present study was aimed to compare the effect of thyme (zataria multiflora boiss), onion (allium cepa) and ziziphora clinopodioides extracts on shelf-life extending of rainbow trout (oncorhynchus mykiss) salted, vacuum packaged fillet, kept at 4°c. for this purpose fish filets were kept in 4 treatment: salted in brine ...

Background and aim: Low-power lasers relief pain in some musculoskeletal disorders and accelerate wound healing process. However, there are few reports on effects of low-power lasers on mast cells. In this study the effects of low-power gallium aluminium arsenide laser (Ga.Al.As.laser) radiation on number and degranulation of mast cells of open skin wound bed of rats were studied using qu...

background: despite the ever-increasing beneficial applications of magnetic nanoparticles in biological systems, few studies have been carried out on the combined effects of nanoparticles (fe and ni) on human health. in the present study the effects of fe2nio4 nanoparticle on inflammatory factors were assessed. methods : twenty-four wistar rats were randomly divided into 3 groups: two groups we...

In this study, the effects of three different bacterial isolates added to vase solution on life were investigated. All significantly increased gerbera cut flowers. While flowers in control was 3 days, period reached up 11 days kept containing bacteria. Daily water uptake decreased with increasing time all treatments. Although there some differences between treatments terms daily uptake, it has ...
