BACKGROUND The objective of this in-vitro study was to evaluate the effect of grape seed extract (oligomericproanthocyanidin complexes [OPCs]) on the bond strength of composite resin to bleached enamel using 5th and 7th generations of bonding agents. MATERIALS & METHODS Eighty maxillary central incisors were randomly assigned to four groups as follows: Group I (n=20): no bleaching (control); ...
abstractferulago angulata boiss. known in iran as chavir, has some bioactive compounds having antioxidant activity. because of its antioxidant activities, it sounded chavir extract can be a good candidate for finding chemopreventive agents having inductive apoptosis properties on cancer cells. in this study, the cytotoxic effects and proapoptotic activities of chavir’s leaf and flower extracts ...
The essential oil from the aerial parts ofJurinea leptoloba DC., collected from Shiraz (South of Iran), was investigated for total phenolic content (TPC), antioxidant and cytotoxic effects. TPC of J. leptoloba oil was determined to be 16.53 ± 5.69 μg gallic acid equivalent/mg sample (μg GAE/mg oil) using the Folin-Ciocalteau assay. The ferric reducing power of the oil was determined 0.117 ± 0.0...
The objective of this study is to develop a new and effective antibacterial agent against food pathogens that poses major threat human health investigate the antioxidant activity plant. Methanol, ethanol, aqueous extracts were analyzed for antimicrobial potency. Eight different microorganisms used in study, one which was yeast. These are pathogens. Antimicrobial testing performed using disc dif...
Potassium-azeloyl-diglycinate is an active ingredient as a sebum normalizer and skin lightening-agent to moisturize treat hyperpigmentation. Anti-aging (AA) cream cosmetic used prevent premature aging. The use of emulsifying agent necessary produce stable cream. One the commonly emulsifying-agents triethanolamine. This study aims formulate AA-cream potassium-azeloyl-diglycinate preparation vari...
the oxidative stress causes many diseases in human, therefore antioxidants have a specialposition in the medicinal chemistry. tyrosol is an important antioxidant with a plenty ofbiological properties. there are many strategies such as clustering single drug units in orderto develop new drugs. the cluster effect can increase drug effects relative to single drug unit.calixtyrosol is the novel clu...
INTRODUCTION Dialysis-induced oxidative stress is one of the mechanisms of atherosclerotic changes. Heparin, used in hemodialysis, is an anticoagulant drug with anti-inflammatory and antioxidant effects. This study was planned in order to evaluate the antioxidant effects of heparin and dalteparin (low-molecular weight heparin). MATERIALS AND METHODS Twenty-two patients underwent 3 hemodialysi...
BACKGROUND Natural chalcones and also their synthetic derivatives have attracted increasing attention due to various pharmacological applications. Development and discovery of new chalcones with antioxidant activities is one of the attracting areas in medicinal and natural product chemistry. OBJECTIVES In the present study, a new series of pyridine based chalcones was synthesized and their an...
BACKGROUND Mangiferin is a polyphenolic xanthonoid with remarkable antioxidant activity. Oxidative stress plays the key role in tert-butyl hydroperoxide (tBHP) induced renal cell damage. In this scenario, we consider mangiferin, as a safe agent in tBHP induced renal cell death and rationalize its action systematically, in normal human kidney epithelial cells (NKE). METHODS NKE cells were expo...
Propofol is an intravenous sedative-hypnotic agent indicated for induction and maintenance of general anesthesia as well as for sedation of intubated, mechanically ventilated adults in intensive care units (ICU). Propofol is characterized by a phenolic structure similar to that of α-tocopherol, and presents antioxidant properties that have been demonstrated both in vitro and in vivo. The aim of...
