Resonance Raman detection of carotenoid antioxidants in living human tissues.
We have used resonance Raman scattering as a novel noninvasive optical technology to measure carotenoid antioxidants in living human tissues of healthy volunteers. By use of blue-green laser excitation, clearly distinguishable carotenoid Raman spectra superimposed on a fluorescence background are obtained. The Raman spectra are obtained within less than a minute, and the required laser light ex...
متن کاملResonance Raman detection of carotenoid antioxidants in living human tissue.
Increasing evidence points to the beneficial effects of carotenoid antioxidants in the human body. Several studies, for example, support the protective role of lutein and zeaxanthin in the prevention of age-related eye diseases. If present in high concentrations in the macular region of the retina, lutein and zeaxanthin provide pigmentation in this most light sensitive retinal spot, and as a re...
متن کاملhydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
Application of Raman Technique in the Detection of Aflatoxins
Aflatoxin is one of the most important topics of research in food contamination . Aflatoxin, a member of the Mycotoxin family, is a secondary metabolite of molds such as Aspergillus Flavus and Aspergillus Parasiticus . These fungi also pollute the crops during production and storage . In the case of the products’ contamination with spores in the desired temperature and humidity conditions, the ...
