Food & Function

Black rice is rich in anthocyanin antioxidants. The present study investigated the lifespan-prolonging activity of black rice extracts (BREs) and its effect on gene expressions of CuZnSOD (SOD1), MnSOD (SOD2), catalase (CAT), methuselah (Mth) and Rpn11 involved in the antioxidant system and ageing of fruit flies. The OR wild type fly was maintained on a control diet or two experimental diets containing 10 mg ml(-1) BRE (BRE10) or 30 mg ml(-1) BRE (BRE30).

Njavara is an important medicinal rice variety of Kerala, India, widely used in Ayurveda as a 'health food' and in the treatment of rheumatoid arthritis, paralysis, neurodegenerative diseases and in rejuvenation therapy. Phytochemical investigations and spectroscopic studies of the diethyl ether fraction of methanolic extract of Njavara Black (NB) rice bran gave three important compounds namely, tricin and two rare flavonolignans- tricin 4'-O-(erythro-β-guaiacylglyceryl) ether and tricin 4'-O-(threo-β-guaiacylglyceryl) ether.

ETHNOPHARMACOLOGICAL RELEVANCE: Lauha bhasma (iron ash) is one of the iron-based herbo-metallic preparations used in Ayurvedic medicine for treating various ailments due to iron deficiency. MATERIALS AND METHODS: The preparation of Lauha bhasma (iron ash) requires normal purification (heat treatment in vegetable and animal products), special purification (treatment with herbal constituents) and calcination steps aimed at converting the raw material to a suitable therapeutic form.

Njavara is an important medicinal rice variety of Kerala, India widely used in Ayurveda for the treatment of rheumatoid arthritis, paralysis, neurodegenerative diseases and in rejuvenation therapy. The study evaluated, for the first time, antitumor effects of the two rare flavonolignans, tricin 4'-O-(erythro-β-guaiacylglyceryl) ether (compound 1) and tricin 4'-O-(threo-β-guaiacylglyceryl) ether (compound 2), isolated from 'Njavara' black.

BACKGROUND: In adult populations, emerging evidence indicates that humans are exposed to arsenic by ingestion of contaminated foods such as rice, grains, and juice; yet little is known about arsenic exposure among children. OBJECTIVES: Our goal was to determine whether rice consumption contributes to arsenic exposure in U.S. children.

Transgenic Research

Genetically modified plants expressing disease resistance traits offer new treatment strategies for human diseases, but at the same time present a challenge in terms of food safety assessment. The present 90-day feeding study was designed to assess the safety of transgenic rice expressing the recombinant human insulin-like growth factor-1 (rhIGF-1) compared to its parental wild rice. Male and female C57BL/6J rats were given a nutritionally balanced purified diet with 20% transgenic rhIGF-1 rice or 20% parental rice for 90 days.

Sake is an alcoholic beverage of Japan, with a tradition lasting more than 1,300 years; it is produced from rice and water by fermenting with the koji mold Aspergillus oryzae and sake yeast Saccharomyces cerevisiae. Breeding research on sake yeasts was originally developed in Japan by incorporating microbiological and genetic research methodologies adopted in other scientific areas. Since the advent of a genetic paradigm, isolation of yeast mutants has been a dominant approach for the breeding of favorable sake yeasts.

Black rice (Oryza sativa L. var. japonica) has been used in folk medicine in Asia. To understand the effects of black rice hydrolyzed peptides (BRP) from germinated black rice, we assessed the expression levels of about 20,000 transcripts in BRP-treated HaCaT keratinocytes using human 1A oligo microarray analysis. As a result, the BRP treatment showed a differential expression ratio of more than 2-fold: 745 were activated and 1,011 were repressed. One of the most interesting findings was a 2-fold increase in hyaluronan synthase 2 (HAS2) gene expression by BRP.

Chemoprevention has become an important area in cancer research due to the failure of current therapeutic modalities. Epidemiological and preclinical studies have demonstrated that nutrition plays a vital role in the etiology of cancer. This study was conducted to determine the chemopreventive effects of germinated brown rice (GBR) in rats induced with colon cancer. GBR is brown rice that has been claimed to be richer in nutrients compared to the common white rice.
