The effect of inclusion of garlic essential oil (EO) at 33, 66 and 100 µg mL(-1), raw garlic (GAR) at 5, 10 and 15 mg mL(-1) and monensin (MON) at 7.5 µg mL(-1) of incubation medium on organic matter digestibility (OMD) was studied with in vitro gas production, ANKOM daisy(II) and conventional in vitro (IVOMD) methods. The material was incubated with sheep ruminal fluid and the experimental des...

The benzoic and cinnamic acids found in forages were tested for their inhibitory effects on digestion of cellulose and hemicellulose by mixed cultures of rumen microorganisms in vitro. Rate and extent of cellulose digestion with the addition of cinnamic acids were determined. The benzoic acids and aldehydes were also compared for their inhibitory potential. Of the benzoic acid derivatives, only...

considering the ease of isolation and high expansion potential of pulp stem/progenitor cells isolated from wisdom and primary teeth they have been implicated as the most reliable autologous cell source in dental tissue engineering. meanwhile, different isolation methods have remarkable impacts on the expansion potential of adult stem cells. in enzymatic digestion method extracted teeth as denta...

pollution of agricultural lands is a widespread problem in mine regions. the transport of the pollutants through the food chain, causes their accumulation s in tissues of plants and animals which endangers their health. this study aimed to measure the concentrations of heavy metals (lead, copper, zinc and manganese) in wheat roots of darreh zaresh villages which might be used for future environ...

The crystalline inclusion of Bacillus thuringiensis, dissolved in 8 m urea containing 10% 2-mercaptoethanol and dialyzed to pH 8.3 to 8.5, was compared with a fraction obtained by the same extraction procedure from spores broken by dry rupture. The two fractions behaved similarly on chromatography with Sephadex G-100 and diethylaminoethyl cellulose. The preparations behaved identically on acryl...

Knowledge of digestion kinetics of solid foods in human stomach, as affected by food processing methods, is critical in establishing processing conditions at the manufacturing stage to achieve desirable release of nutrients in the gastrointestinal tract. The objective of this study was to investigate how roasting affected disintegration and solid release properties of almond in simulated gastri...

We describe a simple and convenient method for processing small amounts of tissue samples for trace-metal measurements by atomic absorption spectrometry, by use of a modified Parr microwave digestion bomb. Digestion proceeds rapidly (less than or equal to 90 s) in a sealed Teflon-lined vessel that eliminates contamination or loss from volatilization. Small quantities of tissue (5-100 mg dry wei...
