Photoluminescence properties of silica aerogel/porous silicon nanocomposites
Authors: Karlash A Yu , Zakharko Yu E , Skryshevsky V A , Tsiganova A I , Kuznetsov G V
Published: August 2010

The luminescent properties of nanocomposite pellets based on silica aerogel and porous Si powder are studied depending on the ratio of chemical compounds. The photoluminescence of nanocomposites is characterized by a red–orange band related to silicon nanoparticles and a blue–green band related to silica aerogel with close values of decay time and activation energy. Remarkable tuning of nanocomposites' photoluminescence spectra in the RGB region is established allowing their use as promising phosphor materials for light-emitting diodes. The outgoing spectra of pellet photoluminescence are guided by the chemical composition ratio, porous Si and silica aerogel technology, and the storage time in ambient atmosphere. It was shown that using the silica aerogel as a dielectric matrix considerably increases the stability of photoluminescence yield of silicon nanoparticles.

While describing the technical and institutional development of the modern credit bureau, The Good Consumer draws special attention to one of the most consequential effects of credit reporting: the invention of financial identity. Formalized systems of credit evaluation produced their own categories of social reality and fostered new forms of economic objectification. The title refers to the “goodness” of credit consumers in several contexts: as prompt paying customers, trustworthy and morally upright citizens, profitable target markets, and collectively as a vital force behind the growth of the twentiethcentury American economy.

A salt- and alkali-tolerant actinomycete strain, YIM 90018T, was isolated from a saline and alkaline soil sample collected from Qinghai, China. Aerial hyphae of strain YIM 90018T were only produced on YIM 82 agar. Vegetative hyphae were well developed and did not fragment. Straight or flexuous (rectiflexibiles) spore chains were produced. The isolate grew well with 25 % (w/v) MgCl2 . 6H2O and at pH 10. All of these characters indicated that strain YIM 90018T belonged to the genus Streptomyces. On the basis of phylogenetic analysis of the 16S rRNA gene sequence, DNA–DNA hybridization and phenotypic characteristics, strain YIM 90018T could be differentiated from all recognized species of the genus Streptomyces. A novel species, Streptomyces sparsus sp. nov., is proposed, with strain YIM 90018T ( = CCTCC AA204019T = DSM 41858T) as the type strain.

A novel strain, 219820T, whose metabolites were found to be active against tumour cells, was isolated and characterized. The isolate belonged to the genus Streptomyces and had white to grey aerial mycelium and long chains of smooth spores in the aerial mycelium. A phylogenetic tree based on 16S rRNA gene sequences showed that strain 219820T had highest similarity to members of the genus Streptomyces and was most closely, albeit loosely, associated with Streptomyces crystallinus NBRC 15401T (98.624 % similarity), Streptomyces melanogenes NBRC 12890T (98.565 %) and Streptomyces noboritoensis NBRC 13065T (98.564 %). However, DNA–DNA relatedness and phenotypic data readily distinguished strain 219820T from these phylogenetically related type strains. It is evident from the combination of genotypic and phenotypic data that strain 219820T represents a novel species of the genus Streptomyces, for which the name Streptomyces sanyensis sp. nov. is proposed; the type strain is 219820T ( = CGMCC 4.5626T  = DSM 42014T).

An anaerobic rod-shaped thermophile was isolated from a hydrothermal vent at Suiyo Seamount, Izu-Bonin Arc, western Pacific Ocean, and was named strain MN14T. The rods were Gram-negative-staining, non-motile without flagella, 2–4 µm long and 0.5 µm wide, and divided by binary fission in the mid-exponential phase. The cells were surrounded by a sheath-like structure (toga) and occurred singly or in chains. Spheroids containing multiple cells were observed not only in the stationary phase, as previously observed for species of the order Thermotogales, but also from the early exponential phase. Transmission electron microscopy revealed that the peptidoglycan in rods partly disintegrated in the early growth phases and that the outer membrane of the spheroids was not completely lined with peptidoglycan. These findings suggested that the spheroids were formed from rods by the disintegration of peptidoglycan and subsequent inflation of the outer membrane. The spheroids eventually generated tiny cells in the periplasmic space, indicating a viviparous mode of proliferation in addition to binary fission. Strain MN14T grew at 40–75 °C, pH 5.0–8.2 and with 0.25–5.20 % (w/v) NaCl, with optimal growth occurring at 68 °C, pH 6.8 and with 2.5 % NaCl. The shortest doubling time was 24 min, assuming that the strain propagated only by binary fission. Elemental sulfur enhanced growth, but was not essential. Thiosulfate was not an electron acceptor for growth. The strain was a chemo-organotroph that grew on yeast extract as the sole growth substrate. Tryptone and starch supported its growth in the presence of yeast extract. The G+C content of the genomic DNA was 31.7 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that this strain belonged to the genus Thermosipho. No significant DNA–DNA hybridization was observed between the genomic DNA of strain MN14T and phylogenetically related species of the genus Thermosipho. Based on this evidence, strain MN14T is proposed to represent a novel species, named Thermosipho globiformans sp. nov. The species epithet globiformans reflects the formation of multicellular and reproductive spheroids by the novel strain. The type strain of this species is MN14T ( = JCM 15059T = DSM 19918T).

Four strains isolated in the last 15 years were revealed to be identical in their 16S rRNA gene sequences to MCRO19, the sequence of which was deposited in GenBank in 1995. In a polyphasic analysis including phenotypic and genotypic features, the five strains (including MCRO19), which had been isolated in four European countries, turned out to represent a unique taxonomic entity. They are scotochromogenic slow growers and are genetically related to the group that included Mycobacterium simiae and 15 other species. The novel species Mycobacterium europaeum sp. nov. is proposed to accommodate these five strains. Strain FI-95228T ( = DSM 45397T  = CCUG 58464T) was chosen as the type strain. In addition, a thorough revision of the phenotypic and genotypic characters of the species related to M. simiae was conducted which leads us to suggest the denomination of the ‘Mycobacterium simiae complex’ for this group.
Optimization of de novo transcriptome assembly from next-generation sequencing data
Authors: Surget-Groba Yann , Montoya-Burgos Juan I.
Published: August 2010

Transcriptome analysis has important applications in many biological fields. However, assembling a transcriptome without a known reference remains a challenging task requiring algorithmic improvements. We present two methods for substantially improving transcriptome de novo assembly. The first method relies on the observation that the use of a single k-mer length by current de novo assemblers is suboptimal to assemble transcriptomes where the sequence coverage of transcripts is highly heterogeneous. We present the Multiple-k method in which various k-mer lengths are used for de novo transcriptome assembly. We demonstrate its good performance by assembling de novo a published next-generation transcriptome sequence data set of Aedes aegypti, using the existing genome to check the accuracy of our method. The second method relies on the use of a reference proteome to improve the de novo assembly. We developed the Scaffolding using Translation Mapping (STM) method that uses mapping against the closest available reference proteome for scaffolding contigs that map onto the same protein. In a controlled experiment using simulated data, we show that the STM method considerably improves the assembly, with few errors. We applied these two methods to assemble the transcriptome of the non-model catfish Loricaria gr. cataphracta. Using the Multiple-k and STM methods, the assembly increases in contiguity and in gene identification, showing that our methods clearly improve quality and can be widely used. The new methods were used to assemble successfully the transcripts of the core set of genes regulating tooth development in vertebrates, while classic de novo assembly failed.
Signatures of positive selection apparent in a small sample of human exomes

Published: August 2010

Exome sequences, which comprise all protein-coding regions, are promising data sets for studies of natural selection because they offer unbiased genome-wide estimates of polymorphism while focusing on the portions of the genome that are most likely to be functionally important. We examine genomic patterns of polymorphism within 10 diploid autosomal exomes of European and African descent. Using coalescent simulations, we show how polymorphism, site frequency spectra, and intercontinental divergence in these samples would be influenced by different modes of positive selection. We examine putatively selected loci from four previous genome-wide scans of SNP genotypes and demonstrate that these regions indeed show unusual population genetic patterns in the exome data. Using a series of conservative criteria based on exome polymorphism, we are able to fine-scale map signatures of selection, in many cases pinpointing a single candidate SNP. We also identify and evaluate novel candidate selection genes that show unusual patterns of polymorphism. We sequence a portion of one novel candidate locus, IVL, in 74 individuals from multiple continents and examine global genetic diversity. Thus, we confirm, narrow, and supplement existing catalogs of putative targets of selection, and show that exome data sets, which are likely to soon become common, will be powerful tools for identifying adaptive genetic variation.

We identified two glycosyltransferases that contribute to the structural diversification of flavonol glycosides in grapevine (Vitis vinifera): glycosyltransferase 5 (Vv GT5) and Vv GT6. Biochemical analyses showed that Vv GT5 is a UDP-glucuronic acid:flavonol-3-O-glucuronosyltransferase (GAT), and Vv GT6 is a bifunctional UDP-glucose/UDP-galactose:flavonol-3-O-glucosyltransferase/galactosyltransferase. The Vv GT5 and Vv GT6 genes have very high sequence similarity (91%) and are located in tandem on chromosome 11, suggesting that one of these genes arose from the other by gene duplication. Both of these enzymes were expressed in accordance with flavonol synthase gene expression and flavonoid distribution patterns in this plant, corroborating their significance in flavonol glycoside biosynthesis. The determinant of the specificity of Vv GT5 for UDP-glucuronic acid was found to be Arg-140, which corresponded to none of the determinants previously identified for other plant GATs in primary structures, providing another example of convergent evolution of plant GAT. We also analyzed the determinants of the sugar donor specificity of Vv GT6. Gln-373 and Pro-19 were found to play important roles in the bifunctional specificity of the enzyme. The results presented here suggest that the sugar donor specificities of these Vv GTs could be determined by a limited number of amino acid substitutions in the primary structures of protein duplicates, illustrating the plasticity of plant glycosyltransferases in acquiring new sugar donor specificities.

Published: August 2010

C4 photosynthesis drives productivity in several major food crops and bioenergy grasses, including maize (Zea mays), sugarcane (Saccharum officinarum), sorghum (Sorghum bicolor), Miscanthus x giganteus, and switchgrass (Panicum virgatum). Gains in productivity associated with C4 photosynthesis include improved water and nitrogen use efficiencies. Thus, engineering C4 traits into C3 crops is an attractive target for crop improvement. However, the lack of a small, rapid cycling genetic model system to study C4 photosynthesis has limited progress in dissecting the regulatory networks underlying the C4 syndrome. Setaria viridis is a member of the Panicoideae clade and is a close relative of several major feed, fuel, and bioenergy grasses. It is a true diploid with a relatively small genome of ~510 Mb. Its short stature, simple growth requirements, and rapid life cycle will greatly facilitate genetic studies of the C4 grasses. Importantly, S. viridis uses an NADP-malic enzyme subtype C4 photosynthetic system to fix carbon and therefore is a potentially powerful model system for dissecting C4 photosynthesis. Here, we summarize some of the recent advances that promise greatly to accelerate the use of S. viridis as a genetic system. These include our recent successful efforts at regenerating plants from seed callus, establishing a transient transformation system, and developing stable transformation.
Normal‐matrix‐based nonlinearH∞attitude tracking for spacecraft
Authors: Hong‐Yu Zhu
Published: August 2010

Purpose

The purpose of this paper is to develop a novel nonlinearH∞control approach for the nonlinear multivariable attitude tracking of rigid spacecraft.

Design/methodology/approach

Based on the transformation of the attitude tracking problem into quaternion error stabilization, the feedback control law is developed by using the normal matrix control theory with the inverse‐additive perturbation description of systems uncertainties, and the Hamilton‐Jacobi‐Isaacs (HJI) partial differential inequality is employed for providing the nonlinearH∞control criteria for the proposed control law. The onboard recursive least squares (RLS) estimation algorithm of inertia tensor is used for the further improving of the normal matrix property of the control system. The RLS algorithm is simple enough for the spacecraft borne computer. Computer simulation is performed to demonstrate the effectiveness of the control law proposed.

Findings

By the normal matrix control theory, the nonlinearH∞control law for attitude tracking is developed without solving the HJI inequality and with the inflight estimation of inertia, the proposed control law is adaptive and robust to the variation of mass properties, and its normality is further improved.

Research limitations/implications

The paper is limited in rigid spacecraft with slowly changing mass property. The flexible influences are not considered.

Practical implications

The paper provides an alternative to the spacecraft researchers/engineers for developing the robust attitude control law with a simple structure and self‐tuning ability.

Originality/value

The paper is the first to provide a robust control based on the normal matrix approach, the HJI inequality, and the estimation of inertia.
Antioxidant contents of pre‐packed fresh‐cut versus whole fruit and vegetables
Authors: Linus Opara Umezuruike , Al‐Ani Majeed R.
Published: August 2010

Purpose

The purpose of this paper is to evaluate the difference in antioxidant contents of pre‐packed fresh‐cut and whole fruit and vegetables as sold in the market.

Design/methodology/approach

Samples of pre‐packed fresh‐cut fruit and vegetables as well as whole produce were collected from the market in Muscat and Oman, and analyzed for vitamin C, lycopene and total carotenoids. Analysis of variance was carried out to determine the level of statistical differences between fresh‐cut and whole fruit and vegetables.

Findings

In both fruit and vegetables, vitamin C contents are higher in whole than fresh‐cut produce, with greater reductions in vitamin C contents of fresh‐cut vegetables than fruit. In both fresh‐cut and whole fruit, lycopene content is 30‐36 times higher in watermelon than the contents of other fruit genotypes studied. Similarly, total carotenoids content of watermelon is six to 21 times higher than other types of fruit studied. Both lycopene and total carotenoids content are higher in whole than fresh‐cut fruit, except in pineapple fruit. In both fresh‐cut and whole vegetables, lycopene content of carrot is three to four times higher than cucumber, and four to six times higher than celery. Implications of these results on public health policy are discussed.

Originality/value

Previous studies on quality of fresh‐cut produce are based on controlled experimental studies using samples of produce from the same batch to compare fresh‐cut versus whole produce. However, consumers in retails stores often have to make a choice between pre‐packed fresh‐cut or whole (un‐cut) produce, which are not usually from the same source or batch. It is therefore essential to understand the differences in nutritional value of whole and pre‐packed fresh‐cuts sold in the market.
Effects of cooking methods on carotenoids content of Omani kingfish (Scomeberomorus commersonL.)
Authors: Linus Opara Umezuruike , Al‐Ani Majeed R.
Published: August 2010

Purpose

Fish is subjected to different methods of preparation and a major challenge facing consumers is maintaining and preserving the nutritional quality of cooked fish. This paper aims to examine the effects of different cooking methods (baking, boiling, deep‐frying, pan‐frying, microwaving and grilling) on total carotenoids and lycopene content in muscle and skin fractions of Omani kingfish.

Design/methodology/approach

Fresh, commercially harvested kingfish samples were purchased from a supermarket and prepared using six commonly used cooking methods. Raw fish samples were used as control. Muscle and skin fish portions for each cooking method and raw samples were analyzed for total carotenoids and lycopene contents.

Findings

The paper finds that cooking methods affected kingfish skin and muscle differently. The positive effects of cooking methods on kingfish muscle scored from high to low are as follows for total carotenoids content: grilling, microwaving, pan‐frying, boiling, deep‐frying and baking; and grilling, microwaving, boiling, deep‐frying, baking and pan‐frying for lycopene content. Baking resulted in the highest increase in both total carotenoids and lycopene contents in the skin, followed by grilling and pan‐frying for total carotenoids. In conclusion, grilling, followed by microwaving, is finds to be the best cooking method for high‐carotenoids content and healthy eating of kingfish.

Originality/value

This is the first paper to be reported on the effects of different cooking methods on total carotenoids content (including lycopene) in skin and muscle of kingfish caught in the warm waters of the Gulf of Oman.
