ferula galbaniflua boiss is one of the natural plants of iran that its exudates, barijeh gum, can be used in food industry. the present study explored the properties of a new gum extracted from tubers of ferula galbaniflua. for this purpose, barijeh gum was extracted from crude exudates by alcoholic extraction with 90% ethanol. the purity of gum was relatively high, and it composed mostly of sa...

This study investigated the antidiabetic activities of different methanolic concentrations D. bulbifera extract. The pulverized dried tubers were cold macerated with methanol in water 30, 50, 70 % v/v. Hyperglycermia was induced by administration a single intraperitoneal dose alloxan (120 mg/kg). Hyperglycermic mice treated various extracts at 50 and 200 mg/kg for 10 days. trend activity 70>50>...

Polysaccharide conjugates were alkali-extracted from green tea (TPC-A). Although it contained 11.80% covalently binding proteins, TPC-A could not bind to the Coomassie Brilliant Blue dyes G250 and R250. TPC-A had no expected characteristic absorption peak of protein in the UV-vis spectrum scanning in the range of 200-700 nm. The UV-vis wavelength of 280 nm was not suitable to detect the presenc...

Procyanidins in plant products are present as extractable or unextractable/bound forms. We optimized alkaline hydrolysis conditions to liberate procyanidins and depolymerize polymers from dried cranberry pomace. Alkaline extracts were neutralized (pH 6-7) and then procyanidins were extracted with ethyl acetate and analyzed by normal phase high performance liquid chromatography. Alkaline hydroly...

The strain MA428-C1 was shaken-cultured (120 strokes/min., 8 cm amplitude) in. a medium (pH7.0) containing 2% glucose, 1.5% soybean meal, 0.3% NaCl, 0.1% K2HPO4, 0.1 % MgSO4-7H2O, 0.0007 % CuSO4-5H2O, 0.0001 % FeSO4-7H2O, 0.0008 % MnCl2-4H2O, 0.0002% ZnSO4-7H2O at 27°C for 5 days. The amount of gougeroxymycin was determined by a cylinder plate method described by one of the authors1}.. About 70...

The protective effect of the aqueous extracted turmeric antioxidant protein on H2O2-induced red blood cell lipid peroxidation and hemolysis was investigated. Turmeric antioxidant protein inhibited lipid peroxidation and hemolysis by 70% and 80%, respectively, and was found to be more effective as an antioxidant than were -tocopherol and curcumin.

PURPOSE This study aimed to investigate the effect of changing the kilovoltage peak (kVp) on the radiographic assessment of dental caries. MATERIALS AND METHODS Seventy-five extracted posterior teeth with proximal caries or apparently sound proximal surfaces were radiographed with conventional E-speed films and a photostimulable phosphor system using 60 kVp and 70 kVp for the caries assessmen...

BACKGROUND Routine tissue processing has generated banks of paraffin-embedded tissue that could be used in retrospective cohort studies to study the molecular changes that occur during cancer development. The purpose of this study was to determine whether a p53 microarray could be used to sequence the p53 gene in DNA extracted from formalin-fixed, paraffin-embedded (FFPE) tissues. METHODS DNA...

This study aimed to elucidate anti-inflammatory activities from extracts of Asterina pectinifera on nitric oxide (NO) production, TNF-α and IL-6 release in lipopolysaccharide (LPS) -stimulated murine macrophage cell, RAW264.7. We prepared the methanolic extracts (60-MAP, 70-MAP, 80-MAP and 90-MAP) , aqueous extract (W-AP) and functional bioactive compound fraction (He-AP and EA-AP) from Asterin...
