objective: nowadays, as the field of neural tissue engineering advances, the fabrication and application of combined structures open a new window of research for the regeneration of nervous system injuries. in this study, chitosan/poly(vinyl alcohol)-carbon nanotube nanocomposites has been exploited as scaffolds. materials and methods: electrospinning was used to fabricate chitosan/poly(vinyl ...
the effects of operating parameters such as feed temperature and permeate-side pressure on the performance of a commercial pva membrane in the dehydration of toluene by a pervaporation (pv) membrane system is studied in the present work. the results obtained indicate that increasing temperature in the range of 40 to 70 °c and reducing permeate pressure in the range of 1 to 10 mmhg increase memb...
Alcohol in Iran is produced mainly from molasses of sugar cane and sugar beet. Other sources of alcohol production like wheat and barley exist, but because of some cultural and political reasons, they cannot be legally used for producing alcohol in Iran. Twenty-six manufacturers in 18 provinces are officially active. The actual capacity of ethanol production with medical purity is about 100mill...
Background and Objective: Emotional intelligence is a kind of emotional information processing which protects individuals against stress and helps them to approach better compatibility and compliance. This study aimed to assess the relation between emotional intelligence and alcohol drinking, cigarette smoking and psychiatric drugs abuse in students’ community. Materials and Methods: Thi...
BACKGROUND The aim of our work was to compare two methods, both based on direct transmethylation with different reagents, BF3/MeOH (boron trifluoride in methanol) or HCl/MeOH (hydrochloride acid in methanol), in acid catalysis, without prior extraction, to find the fast, non-expensive but enough precise method for 9 principal fatty acids (lauric, myristic, palmitic, stearic, oleic, linoleic, li...
The ultrasound contrast agents Echovist(®) and Levovist(®) (Bayer AG, Schering AG, Germany) are based on the release of gas bubbles from milled α-d-galactose. In diagnostic ultrasound, for this class of contrast agents, there is a need for prolonged contrast duration. To investigate if new carbohydrate compositions could prolong the lifetime of the gas bubbles, α-d-galactose was mixed with othe...
Very long-chain saturated fatty acids (VLSFAs) are saturated fatty acids with 20 or more carbons. In contrast to the more abundant saturated fatty acids, such as palmitic acid, there is growing evidence that circulating VLSFAs may have beneficial biological properties. Whether genetic factors influence circulating levels of VLSFAs is not known. We investigated the association of common genetic ...
Leaf traits, structure and water status of Conocarpus lancifolius, a Combretaceae were investigated under semi-arid conditions. The leaf traits examined included leaf area and thickness, stomatal distribution, sclerophylly, succulence and relative water content. Additionally, the types of secretory structures, histochemistry of trichomes, and chemical nature of the cuticlular waxes were evaluat...
Soybean seeds are an important source of vegetable oil and biomaterials. The content of individual triacylglycerol species (TAG) in soybean seeds is difficult to quantify in an accurate and rapid way. The present study establishes an approach to quantify TAG species in soybean seeds utilizing an electrospray ionization tandem mass spectrometry with multiple neutral loss scans. Ten neutral loss ...
Modifications in dietary fatty acid intake might lead to a modification in membrane phospholipid fatty acid composition. The purpose of this study was to investigate relationship between different type of oil consumption and leukocyte membrane phospholipid composition. This study was carried out in subjects utilizing butter (n = 15), margarine (n = 15), fluid oil (n = 15) and mixed types of oil...
