The missense of smell: functional variability in the human odorant receptor repertoire.

Joel D Mainland et al.

Nature neuroscience, 17(1), 114-120 (2013-12-10)

Humans have ~400 intact odorant receptors, but each individual has a unique set of genetic variations that lead to variation in olfactory perception. We used a heterologous assay to determine how often genetic polymorphisms in odorant receptors alter receptor function.

Ginger extract and zingerone ameliorated trinitrobenzene sulphonic acid-induced colitis in mice via modulation of nuclear factor-κB activity and interleukin-1β signalling pathway.

Chien-Yun Hsiang et al.

Food chemistry, 136(1), 170-177 (2012-09-29)

Ginger is a commonly used spice with anti-inflammatory potential. Colitis is the common pathological lesion of inflammatory bowel diseases. In this study, we investigated the therapeutic effects of ginger and its component zingerone in mice with 2,4,6-trinitrobenzene sulphonic acid (TNBS)-induced

In vitro antioxidant and anti-inflammatory activities of 1-dehydro-[6]-gingerdione, 6-shogaol, 6-dehydroshogaol and hexahydrocurcumin.

Feng Li et al.

Food chemistry, 135(2), 332-337 (2012-08-08)

Hexahydrocurcumin, 1-dehydro-[6]-gingerdione, 6-dehydroshogaol and 6-shogaol were evaluated for their antioxidant and anti-inflammatory activities in the present study. The relative antioxidant potencies of ginger compounds decreased in similar order of 1-dehydro-[6]-gingerdione, hexahydrocurcumin>6-shogaol>6-dehydroshogaol in both 1,1-diphenyl-2-picyrlhydrazyl (DPPH) radical-scavenging and trolox equivalent antioxidant
