This study was performed to evaluate the enhancement of functional components of germinated rough rice. Rough rice was germinated at 37 °C for 6 days, and subjected to a high hydrostatic pressure treatment (HPT) at 30 MPa for 24 h (HP24) and 48 h (HP48). Germinated rough rice without HPT (HP0), HP24, and HP48 were analysed for their functional components. The highest γ-aminobutyric acid, total arabinoxylan, and tricin 4′-O-(threo- β-guaiacylglyceryl) ether contents were 121.21 mg/100 g, 10.6%, and 85.82 μg/g, respectively, after HP48 for 2 days. γ-Oryzanol contents increased from 23.19-36.20 mg/100 g (at HP0) to 31.80-40.32 mg/100 g (at HP48). The highest vitamin B (60.99 mg/100 g) and E (4.07 mg/100 g) contents were observed after HP24 for 5 and 2 days, respectively. These results suggest that a combination of HPT and germination efficiently enhances the functional characteristics of rough rice. © 2014 Elsevier Ltd. All rights reserved.

Not Available Laser Fare-Advanced Technology Group (LF-ATG) has teamed with Triton Systems, Inc. (Triton), and Molecular Geodesics, Inc. (MGI), to propose an innovative method for producing multi-material structures that arrest the propagation of acoustic or vibrational energy. The approach forms scattering centers using Laser Engineered Net Shaping (LENS). The scattering elements will be intrinsically periodic due to their layered build format and geometric structure. With proper choice of material densities and elastic moduli, destructive interference of longitudinal and transverse acoustic waves over a specific frequency range has been demonstrated in simple periodic structures (Refs. 1-3). LF-ATG and Triton have applied the LENS solid freeform (SFF) method to generate titanium matrix composites (Ref. 4). We anticipate adapting LENS to provide a more diverse range of materials and periodic geometries in the design, fabrication and test of composite devices that are opaque to mechanical vibrations over a significantrange of frequencies. As shown in this proposal, our approach can achieve precise tailoring of the spatial distribution of the scattering / phase shifting materials in millimeter to tens of centimeter-scale structures. This will potentially enable acoustic and vibration isolation in multiple directions at frequencies ranging from the audible to the ultrasonic.

DESCRIPTION (provided by investigator): Burkholderia pseudomallei is a bioterrorist threat. With the best current therapies, lethality is typically as high as 40%. The overall goal of this application is the development of new drugs against this organism. In Phase I, we will exploit the high sequence similarity between B. pseudomallei and its less virulent relative Pseudomonas aeruginosa to build innovative screens for rapid, safe discovery of effective therapeutic agents. The two species are similar in genome size and composition, with nucleotide and amino acid sequence identities for many genes in the 50-70% range, and in their mechanisms of drug resistance. We will identify genes for new drug targets in B. pseudomallei with orthologs in P. aeruginosa, validate them as essential for survival or growth of both species, and move them into P. aeruginosa as replacements for the native orthologs. Then, we will measure the whole-genome expression profile of P. aeruginosa strains engineered to under express each B. pseudomallei target gene, and use the results to construct a validated set of sensitive whole-cell reporter screens. In Phase II, we will apply these screens to a library of over 100,000 compounds and advance the most promising candidates into lead optimization and efficacy testing in animal models.
