propranolol (pl), a non-selective beta-blocker, is a cardiovascular drug widely used to treat hypertension. the present study was concerned with assessing the cytogenetic effects of this drug on chinese hamster ovary (cho) cell line. mtt assay was then carried out to determine the cytotoxicity index (ic50) of the drug. the ic50 value of pl was 0.43±0.02 mm. to investigate the clastogenic effect...

inspecting the behavior of the rockfill materials is of significant importance in analysis of rockfill dams. since the dimensions of grains in such materials are greater than the conventional sizes suitable for soil mechanics tests, it is necessary to experimentally study them in specific large-scale apparatuses. in this research, the behavior of rockfill materials in two large rockfill dams co...

the rice conversion process is an agricultural transformative industry that consumes a great deal of fossil fuel and electricity. in this study, the effect of different factors on energy consumption, energy consumption index and whitening index were investigated. the experimental design was a split plot design with four whitening periods (15, 30, 45, 60s) (main plot), three rice varieties (khaz...

Hydrothermal treatment of rice, called “Parboiling”, is an ancient traditional process in Asian countries. It consists soaking rough rice water and steaming it, it both reduces the level grain breakage increases head yield during milling. However, parboiling associated with some drawbacks regarding consumer preferences: loss its aroma, reduced rice-kernel whiteness increased kernel hardness. Th...

The relative contribution of acylglycerols and phospholipids to the lipid hydrolysis on milled rice was investigated during storage at 37°C and 70% relative humidity for 50 days. The monoglycerol, diglycerol, and lysophospholipid contents of surface lipid were determined by reversed-phase HPLC. Monoand diglycerol content of milled rice increased during storage from 0.06% to 0.18% (w/w milled ri...

Celiac disease is an autoimmune disease that affects the villi of the small intestine causing abdominal pain, gas, diarrhea, or bad absorption due to gluten intolerance. The only treatment for this disease consists of a lifelong gluten free diet; this is, celiac people cannot consume products containing gluten, such as wheat, barley, and rye, but they can use rice and corn. Thus, rice flour is ...

A study was carried out at the Rice Research Institute of Iran (RRII) to investigate the effect of rollers differential peripheral speed of commercial rubber roll husker and paddy moisture content on the husking index and percentage of broken rice. The experiment was conducted at six levels of rollers differential speed (1.5, 2.2, 2.9, 3.6, 4.3 and 5 m/s) and three levels of paddy moisture cont...
