Convenience rice has become widely popular due to its easy availability for cooking. This study investigated the starch structure and composition of leachate and the microstructure of reheated convenience rice using novel processing technologies: super-heated steaming(SHS), auto-electric cooking(AEC), and pressurized-steam cooking(PSC). Additionally, the effect of two different target water contents(58% and 63%) was also evaluated. The PSC_63% sample had the highest total solids and amylopectin amount in the leachate. The amylopectin amount in the leachate differed significantly based on the targeted water content. Morphological characterization revealed that the swelling of starch and the coated layer on the surface of rice grains were most pronounced in the PSC_63% sample due to the pressure processing. The textural hardness of the AEC_58% sample was much higher than that of the other samples. The PSC_63% sample had the highest textural adhesiveness value, which can be attributed to the highest amylopectin amount in the leachate. Sensory characterization showed that the PSC_63% sample had the highest glossiness, whiteness, moistness, and overall acceptability. The principal component analysis score plots presented substantial differences in the leachate and textural and sensory characteristics of reheated convenience rice among the different processing technologies.

RIP140, a Janus metabolic switch involved in defense functions

Cellular & Molecular Immunology 2013年第1期10卷 7-9页

作者： hun Taeg chung School of Biological Sciences University of Ulsan Meta-Inflammation Basic Research Laboratory Ulsan KoreaCorrespondence: Dr HT Chung School of BiologicalSciences University of Ulsan Meta-lnflammation BasicResearch Laboratory Ulsan Korea.

Since its discovery almost 15 years ago, the receptor-interacting protein RIP140has been determined to be a corepressor of various transcription factors and nuclear receptors. Mice lacking the RIP140 gene are lean, exhibit resistance to high-fat diet- induced obesity and have increased glucose tolerance and insulin sensitivity. In 2008, RIP140 was determined to be a coactivator of nuclear factor-~cB, a master transcriptional regulator of inflammation in immune cells, including macrophages. This year, it was reported that RIP 140 degradation is involved in the resolution of inflammation and in endotoxin tolerance. The general picture that had emerged indicates that RIP140 is a ]anus metabolic switch that convergently regulates metabolic pathways involved in defense func- tions through its pleotropic interactions with transcription factors.

Dear editor,The security of cryptographic techniques heavily relies on the confidentiality of the key, and everything except keys can be made open to public without affecting security. When working with cryptographic services, we must protect the keys from a variety of attackers, including eavesdroppers and malware. A whitebox adversary is an attacker

Direct ink writing of polycaprolactone/polyethylene oxide based 3D constructs

引用

Progress in Natural Science:Materials International 2021年第2期31卷 180-191页

作者： Bin Zhang Se hun chung Susan Barker Duncan Craig Roger J.Narayan Jie Huang Department of Mechanical Engineering University College London Medway School of Pharmacy Universities of Greenwich and Kent School of Pharmacy University College London Joint Department of Biomedical Engineering University of North Carolina and North Carolina State University

There has been increasing interest over recent years in the application of three-dimensional(3 D) printing technologies in the biomedical field. One such method is Direct Ink Writing(DIW); this approach has the potential advantage of allowing room-temperature deposition of materials, presented as an ink, to build complex architectures. DIW offers the ability to process biomaterials containing temperature-sensitive components. Due to the fabrication principles of DIW, there are specific rheological requirements that the ink must exhibit for the 3 D construction. For this reason, hydrogel-based liquid feed stocks have been the focal point of ink development. As a consequence, studies based on inks comprising hydrophobic biomaterials, which are insoluble in water and hence unsuited to the hydrogel approach, have been *** this study, we investigate novel inks that utilize polycaprolactone(PCL), a hydrophobic polymer, as the primary constituent by dissolving the polymer in solvent systems based on dichloromethane(DCM) and acetone(ACE). Moreover, polyethylene oxide(PEO) was incorporated into the PCL systems in order to extend the range of hydrophilicity of the systems. The rheological properties of the inks were investigated as a function of polymer composition and solvent system. Woodpile constructs of PCL and PCL/PEO were fabricated using DIW method and were assessed by a series of material characterisation. The type of solvent system had a noticeable impact on the ink rheology, which ultimately affected the surface properties. The incorporation of PEO particularly enhanced the roughness and wettability of the constructs. Our results support the use of DIW as a new means to process hydrophobic polymers for biomedical applications.

A new heuristic approach was undertaken for the establishment of a core set for the diversity research of rice. As a result, 107 entries were selected from the 10 368 characterized accessions. The core set derived using this new approach provided a good representation of the characterized accessions present in the entire collection. No significant differences for the mean, range, standard deviation and coefficient of variation of each trait were observed between the core and existing collections. We also compared the diversity of core sets established using this Heuristic Core Collection （HCC） approach with those of core sets established using the conventional clustering methods. This modified heuristic algorithm can also be used to select genotype data with allelic richness and reduced redundancy, and to facilitate management and use of large collections of plant genetic resources in a more efficient way.
