Background: Nowadays, radiotherapy is used effectively for treatment of head and neck cancers. Mucositis is one of the most important side effects of radiotherapy. Radio-protective agents protect tissues and cells against the adverse effects due to ionizing radiation and cleave radiation-induced free radicals. Lycopene as a potent antioxidant protects cells against oxidative damage by free radi...

this study examined the possible effects of lycopene at physiological dosage and body fat mass on the humoral immune response in patients with type 2 diabetes mellitus (t2dm). a total of 35 patients with typ2 diabetes mellitus from both sexes aged 54±9 yrs from the iranian diabetes society were introduced into a double blind placebo controlled clinical trial conducted for 2 months. after a 2-we...

the aim of this work was to study the antimicrobial activity of tomato skin lycopene oleoresin against pseudomonas aeruginosa، escherichia coli، staphylococcus ureuse، salmonella typh ، l. monocytogenes ، bacillus cereus، bacillus licheniformis. oleoresin was extracted from tomato peel. lycopene content was measured by spectrophotometer. lycopene oleoresin contained 2321mg lycopene/ 100 g oleor...

coq10 and lycopene are isoprenoid compounds with nutraceutical and pharmaceutical benefits. in this study, the effect of concomitant lycopene biosynthesis on coq10 accumulation in transformed escherichia coli dh5α was studied. a lycopene production pathway including geranylgeranyl diphosphate synthase (crte), phytoene synthase (crtb), and phytoene desaturase (crti) from erwinia herbicola was co...

Evidence for cardioprotective effects of lycopene is inconsistent. Studies of circulating lycopene generally report inverse associations with CVD risk, but studies based on lycopene intake do not. The failure of dietary studies to support the findings based on biomarkers may be due in part to misclassification of lycopene intakes. To address this potential misclassification, we used repeated me...

CoQ10 and lycopene are isoprenoid compounds with nutraceutical and pharmaceutical benefits. In this study, the effect of concomitant lycopene biosynthesis on CoQ10 accumulation in transformed Escherichia coli DH5α was studied. A lycopene production pathway including geranylgeranyl diphosphate synthase (crtE), phytoene synthase (crtB), and phytoene desaturase (crtI) from Erwinia herbicola was co...

Higher plasma lycopene concentrations have been associated with a reduced risk of several chronic diseases. Determinants of lycopene concentrations in humans have received limited attention. We had blood lycopene concentrations and lycopene consumption data available from 111 participants in a two-center cancer prevention trial involving beta-carotene and examined determinants of plasma lycopen...

Doxorubicin is an excellent chemotherapeutic agent utilized for several types of cancer but the irreversible doxorubicin-induced cardiac damage is the major limitation for its use. Oxidative stress seems to be associated with some phase of the toxicity mechanism process. To determine if lycopene protects against doxorubicin-induced cardiotoxicity, male Wistar rats were randomly assigned either ...

       The protective effect of tomato extract and lycopene on acute doxorubicin-induced myocardial toxicity was evaluated in mice. Doxorubicin toxicity, induced by a single intraperitoneal injection (15 mg/kg), was revealed by elevated serum CPKMB and histopathological observations. Tomato extract (1.2 and 2.4 g/kg, i.p.) and lycopene (1.7 and 3.5 mg/kg, i.p.), prevented the rise in serum CPKM...
