TL;DR: Some generalized features of amino acid composition found in thermophilic proteins, including an increase in residue hydrophobicity, a decrease in uncharged polar residues, an increases in charged residues, a increase in aromatic residues, certain amino acid coupling patterns and amino acid preferences for thermophile proteins are presented.
Abstract: Thermophilic proteins show substantially higher intrinsic thermal stability than their mesophilic counterparts. Amino acid composition is believed to alter the intrinsic stability of proteins. Several investigations and mutagenesis experiment have been carried out to understand the amino acid composition for the thermostability of proteins. This review presents some generalized features of amino acid composition found in thermophilic proteins, including an increase in residue hydrophobicity, a decrease in uncharged polar residues, an increase in charged residues, an increase in aromatic residues, certain amino acid coupling patterns and amino acid preferences for thermophilic proteins. The differences of amino acids composition between thermophilic and mesophilic proteins are related to some properties of amino acids. These features provide guidelines for engineering mesophilic protein to thermophilic protein.

TL;DR: The design and implementation of a ForCES-based router (ForTER) is illustrated and the experimental results show the feasibility of the ForTER design and some IETF ForC ES specifications.
Abstract: A router architecture based upon ForCES (Forwarding and Control Element Separation), which is being standardized by IETF ForCES working group, gains its competitive advantage over traditional router architectures in flexibility, programmability, and cost-effectiveness. In this paper, design and implementation of a ForCES-based router (ForTER) is illustrated. Firstly, the implementation architecture of ForTER is discussed. Then, a layered software model, which well illustrates ForCES features, is proposed. Based on the model, design and implementation of Control Element (CE) and Forwarding Element (FE) in ForTER are introduced in detail. Moreover, security for ForTER is considered and an algorithm to prevent DoS attacks is presented. Lastly, experiments of ForTER are illustrated for routing and running routing protocols, network management, DoS attack prevention, etc. The experimental results show the feasibility of the ForTER design. Consequently, the ForTER implementation basically testifies the feasibility of ForCES architecture and some IETF ForCES specifications.

TL;DR: A new, richer model that is capable of more realistically simulating real-world situations is described along with a new GA that produces optimal or near-optimal schedules, and results show that this new model enhances the ability of GA-based approaches, while providing decision support under more realistic conditions.
Abstract: Effective management of complex software projects depends on the ability to solve complex, subtle optimization problems. Most studies on software project management do not pay enough attention to difficult problems such as employee-to-task assignments, which require optimal schedules and careful use of resources. Commercial tools, such as Microsoft Project, assume that managers as users are capable of assigning tasks to employees to achieve the efficiency of resource utilization, while the project continually evolves. Our earlier work applied genetic algorithms (GAs) to these problems. This paper extends that work, introducing a new, richer model that is capable of more realistically simulating real-world situations. The new model is described along with a new GA that produces optimal or near-optimal schedules. Simulation results show that this new model enhances the ability of GA-based approaches, while providing decision support under more realistic conditions.

TL;DR: The results indicate that the method proposed is feasible and effective, and can extract the features of pulse signals accurately, which can be expected to facilitate the modernization of pulse diagnosis.
Abstract: A methodology for the automated time-domain characteristic parameter extraction of human pulse signals is presented. Due to the subjectivity and fuzziness of pulse diagnosis, the quantitative methods are needed. Up to now, the characteristic parameters are mostly obtained by labeling manually and reading directly from the pulse signal, which is an obstacle to realize the automated pulse recognition. To extract the parameters of pulse signals automatically, the idea is to start with the detection of characteristic points of pulse signals based on wavelet transform, and then determine the number of pulse waves based on chain code to label the characteristics. The time-domain parameters, which are endowed with important physiological significance by specialists of traditional Chinese medicine (TCM), are computed based on the labeling result. The proposed methodology is testified by applying it to compute the parameters of five hundred pulse signal samples collected from clinic. The results are mostly in accord with the expertise, which indicate that the method we proposed is feasible and effective, and can extract the features of pulse signals accurately, which can be expected to facilitate the modernization of pulse diagnosis.

TL;DR: An inverse correlation between the fungiform papillae density and the detection threshold was observed, and the highest and lowest detection thresholds were 19.88 +/- 1.31 and 5.85 +/- 0.43 mmol/l, respectively.
Abstract: The aim of this study was to investigate the relationship of fungiform papillae density with taste detection thresholds for sucrose of young male adults. One hundred and eighty two subjects aged 18-23 years (mean age: 21.9 +/- 1.2 years) were included. The densities of fungiform papillae were recorded with the aid of the digital camera, and the taste detection thresholds for sucrose were detected using a modified forced-choice triangle test. The mean density of papillae within all 170 statistic participants was 92.43 +/- 2.64/cm(2), for the 6-mm-diameter stained section of the tongue tip. The average detection threshold was 10.83 +/- 0.24 mmol/l, and the highest and lowest detection thresholds were 19.88 +/- 1.31 and 5.85 +/- 0.43 mmol/l, respectively. Also, an inverse correlation between the fungiform papillae density and the detection threshold was observed.

TL;DR: The results suggest that the purified enzyme was a cathepsin L-like enzyme and that it existed in the form of its enzyme-inhibitor complex or precursor.
Abstract: Cathepsin L-like enzyme was purified from the body wall of the sea cucumber Stichopus japonicus by an integral method involving ammonium sulfate precipitation and a series of column chromatographies on DEAE Sepharose CL-6B, Sephadex G-75, and TSK-GEL. The molecular mass of the purified enzyme was estimated to be 63 kDa by SDS-PAGE. The enzyme cleaved N-carbobenzoxy-phenylalanine-arginine7-amido-4-methylcoumarin with K(m) (69.92 microM) and k(cat) (12.80/S) hardly hydrolyzed N-carbobenzoxy-arginine-arginine 7-amido-4-methylcoumarin and L-arginine 7-amido-4-methylcoumarin. The optimum pH and temperature for the purified enzyme were found to be 5.0 and 50 degrees C. It showed thermal stability below 40 degrees C. The activity was inhibited by sulfhydryl reagents and activated by reducing agents. These results suggest that the purified enzyme was a cathepsin L-like enzyme and that it existed in the form of its enzyme-inhibitor complex or precursor.

TL;DR: The present work demonstrates that both H2O2 and NO are essential for HS-induced hypericin production of H. perforatum suspension cells and reveals a special interaction between the two signal molecules in mediating HS-triggered secondary metabolite biosynthesis of the cells.
Abstract: Heat shock (HS, 40°C, 10 min) induces hypericin production, nitric oxide (NO) generation, and hydrogen peroxide (H2O2) accumulation of Hypericum perforatum suspension cells. Catalase (CAT) and NO specific scavenger 2–4-carboxyphenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO) suppress not only the HS-induced H2O2 generation and NO burst, but also the HS-triggered hypericin production. Hypericin contents of the cells treated with both NO and H2O2 are significantly higher than those of the cells treated with NO alone, although H2O2 per se has no effects on hypericin production of the cells, which suggests the synergistic action between H2O2 and NO on hypericin production. NO treatment enhances H2O2 levels of H. perforatum cells, while external application of H2O2 induces NO generation of cells. Thus, the results reveal a mutually amplifying action between H2O2 and NO in H. perforatum cells. CAT treatment inhibits both HS-induced H2O2 accumulation and NO generation, while cPTIO can also suppress H2O2 levels of the heat shocked cells. The results imply that H2O2 and NO may enhance each other’s levels by their mutually amplifying action in the heat shocked cells. Membrane NAD(P)H oxidase inhibitor diphenylene iodonium (DPI) and nitric oxide synthase (NOS) inhibitor S,S′-1,3-phenylene-bis(1,2-ethanediyl)-bis-isothiourea (PBITU) not only inhibit the mutually amplifying action between H2O2 and NO but also abolish the synergistic effects of H2O2 and NO on hypericin production, showing that the synergism of H2O2 and NO on secondary metabolite biosynthesis might be dependent on their mutual amplification. Taken together, data of the present work demonstrate that both H2O2 and NO are essential for HS-induced hypericin production of H. perforatum suspension cells. Furthermore, the results reveal a special interaction between the two signal molecules in mediating HS-triggered secondary metabolite biosynthesis of the cells.

TL;DR: In this paper, Huber-Carol et al. developed a test statistic to test whether the progressively Type-II censored samples come from an exponential distribution, and the null distribution of the test statistic is also derived.
Abstract: In this article, we develop a test statistic to test whether the progressively Type-II censored samples come from an exponential distribution. The null distribution of the test statistic is also derived. Using the Monte Carlo method, we compare the power of the test statistic with the power of the test statistic T proposed by [Balakrishnan et al., 2002, A test of exponentiality based on spacings for progressively Type II censored data. In: C. Huber-Carol et al. (Eds) Goodness-of-Fit Tests and Model Validity, pp. 89–111 (Boston: Birkhauser).]. The simulation results show that the test statistic performs better than the test statistic T, except for a few cases.

Abstract: Post-genomic tools and technologies have dramatically changed the experimental approaches by which complex biological systems can be characterized. The technique of proteome analysis using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and mass spectrometry has the power to monitor global changes that occur in the protein complement of tissues and subcellular compartments. A new challenge for proteomics has recently been recognized in the differentiation of food proteomes. This report focuses on the present knowledge and future potential application of proteomics in food science and technology.

TL;DR: The AG-I-35S (−60)::Barnase construct can be useful in diminishing pollen and seed formation in plants, providing a novel bisexual sterility strategy for interception of transgene escape and has other potentially commercial use for transgenic engineering.
Abstract: To explore a new approach to generating reproductive sterility in transgenic plants, the barnase gene from Bacillus amyloliquefaciens was placed under the control of an 1853-bp nucleotide sequence from the 3′end of the second intron of Arabidopsis AGAMOUS and CaMV 35S (−60) minimal promoter [AG-I-35S (−60)::Barnase], and was introduced into tobacco through transformation mediated by Agrobacterium tumefaciens. All AG-I-35S (−60)::Barnase transgenic plants showed normal vegetative growth and 28% of the transgenic lines displayed complete ablation of flowering. Two transgenic lines, Bar-5 and Bar-15, were 98.1 and 98.4% sterile, respectively, as determined by seed production and germination. When controlled by AG-I-35S (−60) chimeric promoter, barnase mRNA was detected in the reproductive tissues of transgenic tobacco plants, but not in vegetative parts. This study presents the first application of an AG intron sequence in the engineered ablation of sexual reproduction in plants. The AG-I-35S (−60)::Barnase construct can be useful in diminishing pollen and seed formation in plants, providing a novel bisexual sterility strategy for interception of transgene escape and has other potentially commercial use for transgenic engineering.

TL;DR: Experimental results demonstrate that the method is feasible and effective in recognizing depth, frequency, rhythm, strength and shape of pulse signals, which can be expected to facilitate the modernization of pulse diagnosis.
Abstract: This paper presents a quantitative method for automatic identification of human pulse signals. The idea is to start with the extraction of characteristic parameters and then to construct the recognition model based on Bayesian networks. To identify depth, frequency and rhythm, several parameters are proposed. To distinguish the strength and shape, which cannot be represented by one or several parameters and are hard to recognize, the main time-domain feature parameters are computed based on the feature points of the pulse signal. Then the extracted parameters are taken as the input and five models for automatic pulse signal identification are constructed based on Bayesian networks. Experimental results demonstrate that the method is feasible and effective in recognizing depth, frequency, rhythm, strength and shape of pulse signals, which can be expected to facilitate the modernization of pulse diagnosis.
