Preparation and properties of phosphinic acid-functionalized polyacrylonitrile hollow fiber membrane for heavy metal adsorption.

In this study, phosphorylated polyacrylonitrile hollow fiber membrane was synthesized by reacting aminated polyacrylonitrile hollow fiber membrane with phosphinic acid in a Mannich reaction. The batch single-factor measurements revealed that the phosphorylated polyacrylonitrile (PPAN) membrane had an outstanding ability for Hg adsorption. Thermodynamic investigations indicated that the adsorption process was homogenous, and the theoretical maximum adsorption capacity predicted by the Langmuir model was 371.

Effects of Nitrogen Deficiency on the Metabolism of Organic Acids and Amino Acids in .

Organic acids metabolism and nitrogen (N) metabolism in rice seedlings and the relationship between them are not fully understood. In this study, rice ( L. ssp.

Evaluation on antiosteoporosis of collagen peptides prepared by immobilized protease with eggshell membrane.

Collagen peptides are a potential treatment for osteoporosis due to their antiosteoporosis activity. In this study, we prepared immobilized protease with eggshell membrane as carrier, and then hydrolyzed collagen to obtain collagen peptide. The antiosteoporosis of collagen peptides was confirmed by hBMSC osteogenic differentiation and bone mineralization improvement results.

An overview of the bioactivity of monacolin K / lovastatin.

Monacolin K (MK) is the principal active substance in Monascus-fermentation products (e.g. red yeast rice).

Preventive effects of combinative natural foods produced by elite crop varieties rich in anticancer effects on -nitrosodiethylamine-induced hepatocellular carcinoma in rats.

The World Cancer Research Fund International has released 32 anticancer effects (ACEs) that targeted every stage of cancer processes. Thus, we designed two formulas of natural food combination Diet I and Diet II, mainly produced by elite crop varieties rich in ACEs with different mixture ratios, and evaluated their cancer preventive effects on nitrosodiethylamine (NDEA)-induced hepatocarcinogenesis. After 20 weeks of dietary intervention, Diet I and Diet II reduced incidence, size, and number of hepatic nodules (<0.

Production of Marker-free Transgenic Rice ( L.) with Improved Nutritive Quality Expressing .

Rice seed proteins are lacking essential amino acids (EAAs). Genetic engineering offers a fast and sustainable method to solve this problem as it allows the specific expression of heterologous EAA-rich proteins. The use of selectable marker gene is essential for generation of transgenic crops, but might also lead to potential environmental and food safety problems.

Proteomic Analysis Reveals Coordinated Regulation of Anthocyanin Biosynthesis through Signal Transduction and Sugar Metabolism in Black Rice Leaf.

Black rice ( L.) is considered to be a healthy food due to its high content of anthocyanins in the pericarp. The synthetic pathway of anthocyanins in black rice grains has been identified, however, the proteomic profile of leaves during grain development is still unclear.

iTRAQ-Based Quantitative Proteomics Analysis of Black Rice Grain Development Reveals Metabolic Pathways Associated with Anthocyanin Biosynthesis.

Background: Black rice (Oryza sativa L.), whose pericarp is rich in anthocyanins (ACNs), is considered as a healthier alternative to white rice. Molecular species of ACNs in black rice have been well documented in previous studies; however, information about the metabolic mechanisms underlying ACN biosynthesis during black rice grain development is unclear.

Production of dammarane-type sapogenins in rice by expressing the dammarenediol-II synthase gene from Panax ginseng C.A. Mey.

Ginsenosides are the main active ingredients in Chinese medicinal ginseng; 2,3-oxidosqualene is a precursor metabolite to ginsenosides that is present in rice. Because rice lacks a key rate-limiting enzyme (dammarenediol-II synthase, DS), rice cannot synthesize dammarane-type ginsenosides. In this study, the ginseng (Panax ginseng CA Mey.

Production of oleanane-type sapogenin in transgenic rice via expression of β-amyrin synthase gene from Panax japonicus C. A. Mey.

Background: Panax japonicus C. A. Mey.

Genome re-sequencing and bioinformatics analysis of a nutraceutical rice.

The genomes of two rice cultivars, Nipponbare and 93-11, have been well studied. However, there is little available genetic information about nutraceutical rice cultivars. To remedy this situation, the present study aimed to provide a basic genetic landscape of nutraceutical rice.

Genome-wide analysis of radiation-induced mutations in rice (Oryza sativa L. ssp. indica).

Radiation has been efficiently used for rice germplasm innovation. However, the molecular mechanisms by which radiation induces mutations are still unclear. In this study, we performed whole genome sequencing to reveal the comprehensive mutations in rice treated with radiation.

DNp73 improves generation efficiency of human induced pluripotent stem cells.

Background: Recent studies have found that p53 and its' associated cell cycle pathways are major inhibitors of human induced pluripotent stem (iPS) cell generation. In the same family as p53 is p73, which shares sequence similarities with p53. However, p73 also has distinct properties of its own, such as two alternative promoters to express transactivation of p73 (TAp73) and N terminal deleted p73 (DNp73).
