| tissue distribution & elimination of capsaicin, piperine & curcumin following oral intake in rats. | curcumin, capsaicin and piperine--the bioactive compounds present in spices--turmeric (curcuma longa), red pepper (capsicum annuum) and black pepper (piper nigrum) respectively, have a considerable portion of structural homology. tissue distribution and elimination of these three structurally similar bioactive compounds was examined following their oral intake in rats. | 2010 | 20516541 |
| capsaicin, a component of red peppers, stimulates protein kinase ckii activity. | protein kinase ckii (ckii), a heterotetramer composed of two catalytic (alpha or alpha') subunits and two regulatory (beta) subunits, plays a critical role in cell proliferation and anti-apoptosis. recently, capsaicin was shown to trigger apoptosis. therefore, we examined the effect of capsaicin on ckii activity. although capsaicin induced apoptotic death in hela cells, ckii activity was increased in the cytosolic fraction of hela cells after treatment. capsaicin did not change the expression of ... | 2010 | 20510015 |
| disease resistance to bacterial pathogens affected by the amount of ferredoxin-i protein in plants. | summary ferredoxin-i (fd-i) is a fundamental protein that is involved in several metabolic pathways. the amount of fd-i found in plants is generally regulated by environmental stress, including biotic and abiotic events. in this study, the correlation between quantity of fd-i and plant disease resistance was investigated. fd-i levels were increased by inoculation with pseudomonas syringae pv. syringae but were reduced by erwinia carotovora ssp. carotovora. transgenic tobacco over-expressing fd-i ... | 2007 | 20507485 |
| cellular antioxidant activity of common vegetables. | the measurement of antioxidant activity using biologically relevant assays is important to screen fruits, vegetables, natural products, and dietary supplements for potential health benefits. the cellular antioxidant activity (caa) assay quantifies antioxidant activity using a cell culture model and was developed to meet the need for a more biologically representative method than the popular chemistry antioxidant capacity measures. the objective of the study was to determine the caa, total phenol ... | 2010 | 20462192 |

| development of a modified caco-2 cell model system for studying iron availability in eggs. | a modified caco-2 cell model system was developed for studying iron availability in mixtures of fresh and/or cooked foods subjected to a simulated gastrointestinal digestion. the effect of combining foods containing high levels of ascorbic acid with cooked eggs on ferritin expression in the cells was measured. there was no detectable increase in ferritin with eggs alone, indicating that none of the iron was available for uptake into the cells, but when mixed with orange juice or salad (lettuce, ... | 2010 | 20170171 |
| exposure to aflatoxins in japan: risk assessment for aflatoxin b1. | the intake of total aflatoxins (aft) and aflatoxin b(1) (afb(1)) from food in japan was estimated from aft and afb(1) concentration and frequency data in 24 foods (884 samples) from a 3-year retail market survey from the summer of 2004 to the winter of 2006, and by food consumption data from the national health and nutrition survey performed in 2005. the aft and afb(1) survey revealed that peanut, peanut products, cocoa, chocolate, pistachio, white pepper, red pepper, almond, job's tears, buckwh ... | 2010 | 20155541 |
| capsiate inhibits ultraviolet b-induced skin inflammation by inhibiting src family kinases and epidermal growth factor receptor signaling. | capsiate, one of the major capsaicinoids, is nonpungent and present in sweet pepper. we investigated the effects of capsiate on the ultraviolet b (uvb)-induced inflammatory response in skin and its molecular mechanisms. capsiate-pretreated human keratinocytes inhibited intracellular reactive oxygen species (ros), which activate the mitogen-activated protein kinase and nuclear factor-kappab (nf-kappab) pathways. therefore, we determined the effects of capsiate on these pathways. capsiate inhibite ... | 2010 | 20123015 |
| nsaid-activated gene-1 as a molecular target for capsaicin-induced apoptosis through a novel molecular mechanism involving gsk3beta, c/ebpbeta and atf3. | capsaicin, a natural product of the capsicum species of red peppers, is known to induce apoptosis and suppress growth. non-steroidal anti-inflammatory drug-activated gene-1 (nag-1) is a cytokine associated with pro-apoptotic and antitumorigenic property in colorectal and lung cancer. our data demonstrate that capsaicin leads to induction of apoptosis and up-regulates nag-1 gene expression at the transcriptional level. overexpression of ccaat/enhancer binding protein beta (c/ebpbeta) caused a sig ... | 2010 | 20110283 |
| toward a quarter century of pathogen-derived resistance and practical approaches to plant virus disease control. | the concept of pathogen-derived resistance (pdr) describes the use of genetic elements from a pathogen's own genome to confer resistance in an otherwise susceptible host via genetic engineering [j. theor. biol. 113 (1985) 395]. illustrated with the bacteriophage qbeta in escherichia coli, this strategy was conceived as a broadly applicable approach to engineer resistance against pathogens. for plant viruses, the concept of pdr was validated with the creation of tobacco plants expressing the coat ... | 2010 | 20109666 |
