Background and aims. Since intracanal medicaments can affect the cell viability in periapical tissues, the aim of this study was to evaluate the effect of calcium hydroxide and propolis on pulp fibroblasts. Materials and methods. Two healthy third molars were used as a source to obtain fibroblasts. The fibroblasts were cultured and subjected to 1 mg/mL of propolis and calcium hydroxide. This ex...

Propolis contains a variety of bioactive components and possesses many biological properties. This study was designed to evaluate potential effects of Brazilian green propolis on glucose metabolism and antioxidant function in patients with type 2 diabetes mellitus (T2DM). In the 18-week randomized controlled study, enrolled patients with T2DM were randomly assigned to Brazilian green propolis g...

A recent article by Nakamura R. and colleagues has reported the effects of propolis from different geographical areas on mast cell degranulation [1]. As well as flavonoids, propolis is well known among general population for its anti-allergic properties [2,3]. Actually, propolis has plenty of biological and pharmacological properties and its mechanisms of action have been widely investigated in...

Background and Purpose: Propolis has high potential beneficial bioactive properties such as anti-oxidative, anti­microbial, anti-tumour activities. However, the bitter taste insolubility nature of propolis in water lead to some limitations their usage functional food applications. Experimental Approach: Herein, we evaluated effects nanoencapsulation at different concentration levels (0, 0.4, 0....

In a new propolis type, red Brazilian propolis, 14 compounds were identified (six of them new for propolis), among them simple phenolics, triterepenoids, isoflavonoids, prenylated benzophenones and a naphthoquinone epoxide (isolated for the first time from a natural source). Three of the major components demonstrated significant antimicrobial activity, and two (obtained as inseparable mixture) ...

the purpose of this study was to investigate the therapeutic effects of propolis on biochemical and microbiological parameters in muscle tissues of carp (cyprinus carpio, linnaeus 1758) exposed to arsenic. a sublethal concentration of arsenic (0.01 ppm) and/or 0.01 ppm propolis were administered to fish for seven days. biochemical parameters [ph, lactic acid, total volatile basic nitrogen (tvb-...

BACKGROUND Propolis is a multicomponent active, complex resinous substance collected by honeybees (Apis mellifera) from a variety of plant sources. This study was designed to improve the antimicrobial efficacy of propolis by engineering a niosomal-based system for topical application. METHODS Propolis was extracted in ethanol and screened for total polyphenol content. Propolis-loaded niosomes...

BACKGROUND Vascular endothelial growth factor (VEGF) is a key regulator of pathogenic angiogenesis in diseases such as cancer and diabetic retinopathy. Bee products [royal jelly (RJ), bee pollen, and Chinese red propolis] from the honeybee, Apis mellifera, have been used as traditional health foods for centuries. The aim of this study was to investigate the anti-angiogenic effects of bee produc...

NUTRACEUTICALS 20 MARCH/APRIL 2013 SUMMARY Green propolis derives mainly from vegetative apices of Baccharis dracunculifolia (alecrim plants). However, wide variation detected in the chemical composition suggests contributions from alternative resin plant sources. Prenylated cinnamic acid-derived compounds bearing prenyl groups are predominant and pharmacologically active components of the resi...
