PURPOSE The aim of the present study was to evaluate retrospectively both the results of using a mixture of bovine hydroxyapatite (BHA) and fibrin glue as the only grafting material in the floor of the maxillary sinus and the outcome of nonsubmerged implants placed later. MATERIALS AND METHODS A total of 50 consecutive patients (71 maxillary sinuses) were augmented with a mixture of BHA and f...

The regulation of human GSTA1 by chemical inducers of rodent glutathione S-transferases (GSTs) and the regulatory role of hepatic nuclear factor (HNF) 1 was investigated in Caco-2 cells. Treatment of preconfluent and confluent cells with 12-O-tetra-decanoyl phorbol-13-acetate (TPA), 3-methylcholanthrene (3-MC), 2-tert-butyl-4-hydroxy-anisol (BHA), and phenobarbital (PB) reduced GSTA1 mRNA level...

BACKGROUND Alongside flour, fat is the key ingredient of sponge cakes, including those with long shelf lives. It is an unstable food component, whose quality and nutritional safety depend on the composition and pres- ence of oxidation products. Consumption of fat oxidation products adversely affects the human body and contributes to the incidence of a number of medical conditions. Qualitative c...

Human beings are exposed to a multitude of carcinogens in their environment, and most cancers are considered to be chemically induced. Here we examined differences in genetic alterations in rat forestomach tumors induced by repeated exposure to a genotoxic carcinogen, N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) or N-methylnitrosourethane (MNUR), and chronic treatment with a non-genotoxic carcin...

lipid oxidation has adverse effect on food deterioration and human health. the antioxidant activity of fennel seed extracts (fse) was evaluated by synthetic antioxidant. its oxidative stability was compared in olive oils in concentrations of bha (75 ppm), bht(75 ppm) and  1:1 bha to bht ratio. peroxide (pv), p-anisidine (av) and totox values were evaluated to assess the extent of oil deteriorat...

Previous work pointed out the possibility to enhance the nutritional value of meat products using long chain omega-3 PUFA enriched emulsions. Oil-in-water emulsions elaborated with a mixture of algae and linseed oils (15:10) in order to be used as functional ingredient were stabilized with BHA (butylhydroxyanisol) or with a lyophilized water extract of Melissa officinalis L. (Lemon balm). The l...

A significant problem associated with the commercial acceptance of biodiesel is poor oxidative stability. This study investigates the effectiveness of various natural and synthetic antioxidants [a-tocopherol (a-T), butylated hydroxyanisole (BHA), butyl-4-methylphenol (BHT), tert-butylhydroquinone (TBHQ), 2, 5-di-tert-butylhydroquinone (DTBHQ), ionol BF200 (IB), propylgallate (PG), and pyrogallo...

A novel well-defined linear poly(ε-caprolactone) (P1) containing terminal azobenzene and ethyne groups was successfully synthesized through tin-catalyzed ring-opening polymerization of ε-caprolactone in the presence of N,N′-bis(2-hydroxyethyl)-4-(3ethynylphenylazo)aniline (BHA) in bulk. Subsequent reactions allowed the synthesis of the corresponding bromoester end-functionalized polymer (P2), w...

In this study, effects of thyme/cumin essential oils (EO) and butylated hydroxyl anisole (BHA)/butylated hydroxyl toluene (BHT) on physicochemical properties and storage stability of chicken patties were compared in different storage periods (0, 3, 7, 14, 21, and 28 d). It was found that there were significant (P < 0.05) differences between physicochemical properties of patty samples treated wi...

Natural antioxidants have gained considerable interest in recent years for their role in preventing the auto oxidation of fats, oils and fat containing food products. In the present study, three plant foods viz., amla (Emblica officianalis), drumstick leaves (Moringa oleifera) and raisins (Vitis vinifera) were used as sources of natural antioxidants. All the three extracts exhibited a high perc...
