Rosemary (Rosmarinus officinalis) leaves possess a variety of bioactivities. Previous studies have shown that the extract of rosemary leaves from supercritical fluid extraction inhibits the expression of inflammatory mediators with apparent dose-dependent responses. In this study, three different extraction conditions (5000 psi at 40, 60, and 80 °C) of(More)
Mithramycin (Mith) forms a drug-metal complex with a 2:1 stoichiometry by chelation with a Ni(II) ion, which was determined using circular dichroism spectroscopy. Mith exhibits an increased affinity (~55 fold) for Ni(II) in the presence of DNA compared to the absence of DNA, suggesting that DNA acts as an effective template to facilitate chelation. Also, we(More)
Monascus sp. fermented products are known for their antihypercholesterolemic effects; however, their antioxidant and anti-inflammatory activities are different from those of many plant-derived foods. To evaluate the effect of turmeric addition into the medium on the antioxidant and anti-inflammatory activities of Monascus pilosus fermented products, we(More)
Natural products play an important role in promoting health with relation to the prevention of chronic inflammation. N(6)-(2-Hydroxyethyl)adenosine (HEA), a physiologically active compound in the medicinal mushroom Cordyceps cicadae, has been identified as a Ca(2+) antagonist and shown to control circulation and possess sedative activity in pharmacological(More)
A high-fat diet contributes to the etiology of metabolic diseases. As the liver plays a crucial role in metabolism, an insight into the hepatic proteomics will help to illustrate the physiological effect of a high-fat diet. Fourteen nine-week old male Syrian hamsters were maintained on either control (C) or high-fat (HF) diets (0.2% cholesterol +22% fat)(More)
Obesity is a global health problem. Because of the high costs and side effects of obesity-treatment drugs, the potential of natural products as alternatives for treating obesity is under exploration. 2,4,5-Trimethoxybenzaldehyde (2,4,5-TMBA) present in plant roots, seeds, and leaves was reported to be a significant inhibitor of cyclooxygenase-2 (COX-2)(More)
OBJECTIVE Hypercholesterolemia is a major risk factor for atherosclerosis. The fermented products of Monascus sp. have been known for their antihypercholesterolemic effect; however, the studies mostly have focused on the inhibition of cholesterol biosynthesis in liver. In this study, we examined whether fermented products of Monascus pilosus have regulatory(More)
Hypercholesterolemia initiates the atherogenic process; however, chronic inflammation promotes atherogenesis. Monascus spp. fermented products are recognized for their anti-hypercholesterolemic effect, but their anti-inflammatory activity is not as significant as that of many plant-derived foods. To enhance the anti-inflammatory function of Monascus pilosus(More)
Cordyceps cicadae is a parasitic fungus that hibernates inside a host (Cicada flammata Dist.) and then grows its fruiting body on the surface of the insect. The complete insect/fungus combination of C. cicadae has been widely applied in Chinese traditional medicine. Recent studies have demonstrated that the medicinal benefits of cultured mycelia are as(More)
