We studied the antioxidant activities of the essential oils of Zataria multiflora Boiss. (ZEO) and Bunium persicum (Boiss.) B. Fedtsch (BEO) in mixed form on linseed oil using (DPPH•), ­(­ABTS•+), H2O2 scavenging, and reducing power assays. After calculation of IC50 for ZEO and BEO separately, interactions of the essential oils were investigated at the form of mixture and the results were given...

In the present study, we investigated the ability of an immobilized phospholipase A1 (PLA1) in degumming of soybean oil. The enzyme was immobilized by simple adsorption on bentonite without any further modification. The free and immobilized PLA1 were characterized by Fourier Transform InfraRed (FT-IR) spectroscopy and X-Ray Diffraction (XRD). The immobilizat...

ABSTRACTAn oxidation stability is very important for a long-term storage of biodiesel. Some physical (density and viscosity) chemical properties (acid value, iodine peroxide value) were analyzed to predict the biodiesel produced from Waste Cooking Oil (WCO). WCO one potential feedstocks in Indonesia, which large cooking oil consumer. Biodiesel was by transesterification process 60 oC temperatur...

The influenza surface glycoprotein hemagglutinin (HA) is a potential target for antiviral drugs because of its key roles in the initial stages of infection: receptor binding and the fusion of virus and cell membranes. The structure of HA in complex with a known inhibitor of membrane fusion and virus infectivity, tert-butyl hydroquinone (TBHQ), shows that the inhibitor binds in a hydrophobic poc...

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...

The transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) coordinates expression of genes required for free radical scavenging, detoxification of xenobiotics, and maintenance of redox potential. Previously, activation of this pleiotropic response was neuroprotective in cell culture models that simulate components of stroke damage. However, the role of Nrf2 in limiting stroke d...

Background: The short-time creep behavior for a series of biodegradable nanocomposites which is used as implantable device into body is a crucial factor. In the current paper, we aimed to study the effect of bioactive glass nanoparticles (BGn) on creep and creep-recovery behaviors of PLA/PCL blends at different given load and different applied temperatures. Method: A series of biodegradab...

Background: Platanus species are widely cultured around the world and considered an important cause of allergic reactions. In the present study, we developed a sandwich ELISA to quantify Pla or 3 allergen in P. orientalis pollen extracts grown near high-traffic roads and compared it to pollen extracts collected from rural areas as control. Methods: Pollen samples were collected from three po...

platanus acerifolia, london plane tree, a significant source of airborne allergens, is widely grown in shanghai and other cities in china. in recent decades, little has been known regarding the influence of the allergens on sensitizing the population in the shanghai area. the aims of this study were to purify and characterize the two major allergens and to confirm the immunological activities o...
