The aim of the present study was to evaluate the capacity of some root canal irrigants to induce genetic damage and/or cellular death in vitro. Murine fibroblast cells were exposed to ethylenediaminetetraacetic acid (EDTA), sodium hypochlorite (NaOCl), MTAD™ and citric acid in increasing concentrations for 3 h at 37ºC. The negative control group was treated with vehicle control (phosphate buffe...

In this research, the diffusion coefficient of phosphate ions in agarose-citric acid diffusive gel has been studied. The layer was prepared by mixing 1.5% agarose solution with addition citric solutions at various concentration. casted between two glass plates which were separated using a spacer 0.1 cm thickness and clamped together three sides. Gel formed for 15 minutes an oven 40oC. then calc...

The antibody fraction (less than 6ml) was added to immobilized enzyme (2ml of packed gel). The antibodies were recycled for 2h and the unattached antibodies washed from the gel for 1 h. Specific antibodies were eluted by washing with citric acid (0.1 M, pH2.2). Experiments marked with an asterisk were performed simultaneously. The molecular weights of immunoglobulin G and creatine kinase were t...

Citric acid is the most widely used organic acid in the field of foods and beverages as an acidulant as well as in pharmaceutical and chemical products. Demand for citric acid has increased worldwide, including in Turkey. It is generally produced by surface or submerged fungal fermentation mainly with Aspergillus niger. However, the highest citric acid production has been obtained with the subm...

Well-crystallized BiOCl nanoplates with exposed {001} facets were synthesized by a facile electrochemical anodic oxidation method. The thickness of the nanoplates decreases with increasing citric acid content in the electrolyte. The optical absorption edge of the BiOCl nanoplates shifts to a longer wavelength with citric acid. The BiOCl nanoplates obtained with citric acid show a high photocata...

In this study, cobalt aluminate was prepared by a sol-gel method. XRD and FTIR analyses of the precursors obtained at 300 °C for 12 h revealed that type complexing agent used in synthesis affects pyrolysis step. An amorphous phase using citric acid as agent. A beginning crystallization observed agents such polyacrylic glycine. The structural investigation starting reagents lines exhibit charact...

objective: polyphenol oxidase or ppo (ec 1.14.18.1) is considered the enzyme responsible for quality deterioration and browning in different fruits during postharvest period. the objective of this study was to evaluate the antibrowning (inhibition of polyphenol oxidase activity) effect of cysteine, ascorbic acid, citric acid, kojic acid and glycine at two different ph (6 and 7) in  hawthorn. me...

ABSTRACT. Nano hydroxyapatite (n-HAp) and its composites have shown a great development in the field of tissue regeneration controlled drug delivery due to good biocompatibility bioactivity behavior. Furthermore, HAp-based nanocomposites enhance mechanical properties. These synthetic HAp can also be tailored fabricate scaffold with porosity which facilitate growth cell engineering. In this pape...
