Gout is the most frequent form of inflammatory arthritis in the world. Its prevalence is particularly elevated in specific geographical areas such as in the Oceania/Pacific region and is rising in the US, Europe, and Asia. Gout is a severe and painful disease, in which co-morbidities are responsible for a significant reduction in life expectancy. However, gout patients remain ostracized because the disease is still considered “self-inflicted”, as a result of unhealthy lifestyle and excessive food and alcohol intake. While the etiology of gout flares is clearly associated with the presence of monosodium urate (MSU) crystal deposits, several major questions …

Journal of Food and Drug Analysis
Glucose is an important energy source for cells. Glucose transport is mediated by two types of glucose transporters: the active sodium-coupled glucose cotransporters (SGLTs), and the passive glucose transporters (GLUTs). Development of an easy way to detect glucose uptake by the cell can be valuable for research. 1-(N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl) amino)-1-deoxy-D-glucose (1-NBDG) is a newly synthesized fluorescent glucose analogue. Unlike 2-NBDG, which is a good substrate of GLUTs but not SGLTs, 1-NBDG can be transported by both GLUTs and SGLTs. Thus, 1-NBDG is useful for the screening of SGLT1 and SGLT2 inhibitors. Here we further characterized 1-NBDG and compared it …

Journal of Food and Drug Analysis
Herein, we describe a rapid, sensitive, and nondestructive method—extractive nanoelectrospray ionization-mass spectrometry (EnESI-MS)—for traditional Chinese medicine (TCM) authentication. The mass-spectral fingerprints of volatile compounds released from various TCMs can be rapidly acquired using EnESI-MS without sample pretreatment. EnESI-MS was applied to successfully differentiate between two commonly used medicinal herbs, Schisandra Chinensis and Schisandra sphenanthera, which are morphologically similar but exhibit different therapeutic effects. Specific volatile compounds of each herb in a ten-component Chinese herbal product, Jia Wei Xiao Yao San, were also identified, and the method was applied to discriminate between the commercial product and a substandard version.

Journal of Food and Drug Analysis
Natural products have long been considered as a kind of complementary medicine. In this study, we investigate the apoptotic effect of essential oils of Toona sinensis roots (TSR) on human clear cell renal cell carcinomas (ccRCC). The sesquiterpene content of TSR essential oil was determined via GC/MS analysis. TSR decreased ccRCC cell viabilities, inducing ROS generation and reduction of the mitochondrial membrane potential. Moreover, TSR inhibited Bcl-2 and Hsp90 expression but increased PARP-1 cleavage and cytochrome c release. Akt, mTOR and NF-kB phosphorylation and HIF-a expression were all inhibited, which likely contributed to the anti-proliferative and anti-adhesive effects of TSR.
