This study was designed in order to correlate the flavonoid and lipoidal matters content of Spinach roots and flowers to their hypolipidemic potential. The total flavonoid content was measured via complexation with aluminum chloride while determination of fatty acids methyl esters and unsaponifiable matters contents in both organs was performed using GC/MS. In an in vitro study, the crude etha...

BACKGROUND Reducing the nicotine content in cigarettes could improve public health by reducing smoking and toxicant exposure, but may also have unintended consequences on alcohol use. The primary objective of this study was to examine the effect of reducing the nicotine content in cigarettes on alcohol outcomes. The secondary aim was to examine whether the effects of these cigarettes on alcohol...

Effects of formulation parameters on the fractional release profile of diclofenac sodium from matrices having the manufacturing formulation ingredients are studied. As a content of cetyl alcohol (rate controlling agent) in the matrix increases, the fractional release decreases. The fractional release increases either by increasing sucrose content outside the granule or by decreasing sucrose...

background and objectives: kefiran (kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. the expansion of mixed systems can propose kefiran and polyvinyl alcohol (pvoh) as a new composite film. materials and methods: solutions of 20 gra...

In a former communication* the use of alcohol was proposed as a basis for a very rapid means of determining the moisture content of soils and possibly of other materials. Th~ form of alcohol that was then suggested was ethyl alcohol. In order to ascertain whether there are other liquids that would be more satisfactory than ethyl alcohol, an investigation has been conducted in which a large numb...

Therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. The expansion of mixed systems can propose kefiran and polyvinyl alcohol (PVOH) as a new composite film. Materials and Methods: Solutions of 20 gr...

In order to produce biodiesel from waste cooking oil and optimize its yield, a two-stage process of esterification/ transesterification has been used in this study. First, we used the acidic catalysts H2SO4 in order to diminish the content of free fatty acid (FFA) in oil that caused reducing the oil acidity from 6.1% to 0.57% through esterification. Then, the biodiesel was produced by transeste...
