objective(s):the present study reports the development and validation of a sensitive and rapid extraction method beside high performance liquid chromatographic method for the determination of crocetin in human serum. materials and methods:the hplc method was carried out by using a c18 reversed-phase column and a mobile phase composed of methanol/water/acetic acid (85:14.5:0.5 v/v/v) at the flow...

Ultrasonic array imaging is used in nondestructive testing for the detection and characterization of defects. The scattering behavior any feature can be described by a matrix coefficients, called matrix. This information characterization, contrary to image-based analysis, allows defects at subwavelength scale. However, defect coefficients are, practice, contaminated other nearby scatterers or s...

Polysaccharides are of great interest to scientists due their special properties such as non-toxicity, specific physical and chemical properties, therapeutic effects, biodegradability, biocompatibility. In recent years, research has been intensively conducted on the isolation polysaccharides from natural raw materials by conventional non-conventional methods, determine structure biological acti...
