Bile acid concentrations were estimated enzymatically in fasting and postprandial (two-hour) serum samples from 18 normal subjects and 30 patients with histologically proven hepatobiliary disease. The serum bile acid concentration was less than 15 mumol/1 in normal subjects and did not increase postprandially. The fasting serum bile acid concentration was raised in 27 of the patients with hep...

approximately 10-30% of tomatoes are wasted during processing. tomato pomace consists of crushed skin and seeds of tomatoes. seeds might be considered as a potential source of vegetable oil. the extracted oil is high in unsaturated fatty acids, namely linoleic acid. the extracted oil after purification or refining might be employed for consumption. the object of this study was to evaluate the e...

in this study, removal of acid blue 62 from aqueous solution by mesoporous silicate mcm-41 modified by aminopropyltriethoxysilane (aptes) composite was studied. properties of synthesized composite were analyzed and confirmed by sem, edx and ftir. results show that langmuir adsorption isotherm has the best compatibility with the results of experiments. kinetic analysis using pseudo-first-order m...

â  performance and capacity of sulfur recovery unit (sru) are greatly affected by the h2s:co2 ratio of the acid gas stream. the acid gases in iran contain around 35 mol% h2s and 60 mol% co2. this low concentration of h2s calls for more complex sulfur plant, larger equipments, and higher costs. acid gas enrichment processes (age) is run to upgrade low quality acid gas collected from gas treating...

legumes are rich sources of protein and consider a good alternative to make a protein films. in this study, central composite design to investigate the simultaneously effect of the grasspea protein isolates (2 - 10 percent), glycerol (0.5 - 7%) and oleic acid (0 - 2%) on properties of edible films made from grasspea protein isolates, such as thickness, density, percentage of solubility in water...

many factors, particularly the planted cultivar for oil production and climatic conditions, can affect olive oil quality. this research was conducted with 12 olive cultivars in olive research stations with different climatic conditions (taroum, roodbar, gorgan, kazeron and sarpolezehab). fruits with 4-4.5 ripening indices were harvested in each region. fatty acids composition data were analyzed...

introduction: early differentiation of biliary atresia from neonatal hepatitis is of utmost importance, since on time surgery of biliary atresia significantly improves the outcome. hepatobiliary scintigraphy is an integral part of diagnosis work-up of these patients; however its specificity for diagnosis of biliary atresia is suboptimal. in this study we evaluated the value of ursodeoxycholic a...

background and aims: walnuts are good sources of polyunsaturated fatty acids (pufa) and polyphenols which have beneficial effects such as proper growth, decreasing coronary heart disease, prevention of several kinds of cancer, anti-inflammatory and anti-mutagenic activities. in this study, the fatty acid content and antiradical activity of different walnut (juglans regia l.) genotypes grown in ...

The chemical composition, main physicochemical properties, and nutritional value of seed flour and seed oil of Lannea kerstingii were studied. The results indicated that seeds contained 3.61% moisture, 57.85% fat, 26.39% protein, 10.07% carbohydrates, and 2.08% ash. Potassium was the predominant mineral, followed by magnesium and calcium. The essential amino acids were at higher levels than the...

spectropholornetrie technique is used to evaluate binding of the vanadium(1u) ion to a water solublecaruc[4] arene molecule in aqueous solution. on the basis of the calculated value formation constant at25rc.we found that the eomplexation of this metal on is very favored towards 25, 26, 27, 2stetrahydroxy-5, 11, 17, 23-tetnmulphonalic acid-calix[0]arenegaussian 03 package.
