BACKGROUND
The aetiology of inflammatory bowel disease (IBD) remains poorly understood. Recent evidence suggests an important role of gut microbial dysbiosis in IBD, and this may be associated with changes in faecal volatile organic metabolites (VOMs).
OBJECTIVE
To describe the changes in the faecal
Antibiotic treatment for infectious diseases commonly leads to host inflammatory responses. Molecules with bifunctional antibacterial and anti-inflammatory properties could provide a solution for such clinical manifestations. Here we report such bifunctional activity for a diarylheptanoid
BACKGROUND
Inflammation triggered by oxidative stress can cause various ailments, such as cancer, rheumatoid arthritis, asthma, diabetes etc. In the last few years, there has been a renewed interest in studying the antioxidant and anti-inflammatory action of plant constituents such as flavonoids and
Dysregulated production of reactive oxygen species (ROS) during oxidative stress has been associated with a number of inflammatory and age-related degenerative diseases. ROS can directly react with DNA to form oxidized DNA bases. Direct protein oxidation and carbonylation occur on certain amino acid
Diarylheptanoid A, 5-hydroxy-7-(4'-hydroxy-3'-methoxyphenyl)-1-phenyl-3-heptanone, is a naturally occurring phytochemical ingredient isolated from the rhizome of Alpinia officinarum. In order to confirm the anti-inflammatory activity of diphenylheptane A, we investigated its effects on
Certain medicinal plants contain anti-inflammatory and antioxidative substances that can exert chemopreventive effects. Our previous studies have demonstrated that the methanol extract of Alpinia oxyphylla Miquel (Zingiberaceae) inhibits tumor promotion in mouse skin. Two major diarylheptanoids
Recently, considerable attention has been focused on identifying naturally occurring chemopreventive substances capable of inhibiting, retarding, or reversing the multi-stage carcinogenesis. A wide array of phenolic substances, particularly those present in dietary and medicinal plants, have been
The rhizome of Alpinia officinarum Hance, a popular spice used as a condiment in China and Europe, has various reported bioactivities, including anticancer, anti-inflammatory and antioxidant effects. However, its anti-angiogenic activity has not previously been reported. In this study, a
The genotoxic effects of multi-walled carbon nanotubes (MWCNTs) were examined by using in vitro and in vivo assays. MWCNTs significantly induced micronuclei in A549 cells and enhanced the frequency of sister chromatid exchange (SCE) in CHO AA8 cells. When ICR mice were intratracheally instilled with
