<abstract xmlns="http://www.w3.org/1999/xhtml">Hepatitis is a global disease that is on the rise and is currently the cause of more deaths than the human immunodeficiency virus each year. As a result, there is an increasing need for antivirals. Previously, effective antivirals have been found in the form of substrate-mimetic antiviral protease inhibitors. The application of machine learning has been used to predict cleavage patterns of viral proteases to provide information for future drug design. This study has successfully applied and compared several machine learning algorithms to hepatitis C viral NS3 serine protease cleavage data. Results have found that differences in sequence-extraction methods can outweigh differences in algorithm choice. Models produced from pseudo-coded datasets all performed with high accuracy and outperformed models created with orthogonal-coded datasets. However, no single pseudo-model performed significantly better than any other. Evaluation of performance measures also show that the correct choice of model scoring system is essential for unbiased model assessment.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Some mineral nutrients may help to alleviate cadmium stress in plants. Therefore, influence of Fe, Ca, and Zn supplements on photosynthesis light reactions under Cd stress studied in two Indian rice cultivars namely, MO-16 and MTU-7029 respectively. Exogenous application of both Fe and Ca ions helped to uphold quantum efficiency and linear electron transport during Cd stress. Also, recovery of biomass noticed during Cd treatment with Fe and Ca supplements. It was found that accumulation of carotenoids as well as non photochemical quenching enhances with Fe, Ca, and Zn supplements. Chlorophyll a/b ratio increased with Cd accumulation as a strategy to increase light harvest. Lipid peroxidation level was ascertained the highest during Cd plus Zn treatments. Above results point that both Fe and Ca ions supplements help to alleviate Cd stress on photosynthesis light reactions of rice plants.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The soil degraded and changed by the anthropic activity must be monitored and the awareness of the intrinsic processes will allow a pertinent analysis of the effects of the application of the new technologies on the management and the sustainability of the soil.Two natural and anthropic Phaeozems were analyzed from the point of view of chemical, microbiological characteristics, quality and composition of organic compounds.Total values of microbial biomass and bacterial and fungal counts were generally twice higher in Calcaric Phaeozems than in Verti-Stagnic Phaeozems.The content of humic precursors in Calcaric Phaeozems was quantitatively higher than that determined in Verti-stagnic Phaeozems, with a total content of phenols of 14.6mgGAExg−1d.m., polysaccharides and proteins of 97mgxg−1, respectivelly 16.6mgxl−1.The ascending chromatograms showed specific distribution and higher density of the organic compounds in the CAFT sub-fraction of the Verti-stagnic Phaeozems. Pfeiffer specific chromatograms revealed an enzyme activity much higher than average at the Verti-stagnic Phaeozems, with a well-characterized functional diversity. The nutritional reserve appeared increased but poorly diversified in the Calcaric Phaeozems. Humification processes are intense, colloidal substances are present, the mineral component is very well integrated in the organic material at the Verti-stagnic Phaeozems and complex protein content is well revealed especially in the Calcaric Phaeozems.Capillary dynamolysis reflected a characteristic pattern of Phaeozems soils, with particularities for each soil type, represented by colors, contours and particular forms of the specific structures developed.Both soils presented good conditions for sustaining vegetation either natural or cultivated but results indicated that anthropic intervention determined a more dynamic mineralization of organic matter. Further monitoring of soil organic matter dynamics is needed and adjusting management practices for conservation of biodiversity and global ecosystem protection against the effect of anthropic intervention.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Activated charcoal was microencapsulated with <italic>Lactobacillus acidophilus</italic> 314 previously adapted for urea uptake. The creatinine removal capacity of this combination microcapsule was evaluated in-vitro in media simulating the small intestine. Results show that microcapsules containing both activated charcoal and <italic>L. acidophilus</italic> 314 demonstrated potential for decreasing creatinine. Interestingly, when co-encapsulating both activated charcoal and <italic>L. acidophilus</italic> 314 a smaller decrease in creatinine was observed than when encapsulating them separately. However, co-encapsulated microcapsules were more stable in various parts of the gastrointestinal system and survived longer in storage. These results suggest the feasibility of using microcapsules containing activated charcoal and probiotic bacteria as oral adjuvants for creatinine removal and provides a theoretical model for the use of these microcapsules to remove any unwanted metabolite.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Morning Glory (<italic>Ipomoea purpurea</italic> (L.) Roth.) is a climbing plant known for its ornamental properties and ease of cultivation in temperate climates. Quality and colour of flowers and leaves, especially in the production of ornamentals, are important parameters both for producers and for customers. This study aimed to investigate the changes in photosynthetic pigment, protein and dry matter content of <italic>in vitro</italic>-propagated <italic>I. purpurea</italic> following chitosan treatment with different polymerization degrees (DP) and to determine the indirect effect of this biopolymer on leaves of the plant. Nodal explants of <italic>I. purpurea</italic> were cultured in medium supplemented with 5, 10 and 20 mg L−1 concentrations of a chitosan oligomers mixture with a variable degree of polymerization (DP) ranging from 2 to 15 or chitosan polymer with DP of 70. It was found that both oligomeric and polymeric chitosan treatments increased chlorophyll-a contents in the leaves when compared to the chitosan-naïve control group. Polymeric chitosan stimulated chlorophyll-b and carotenoid synthesis more effectively than the oligomer mixture. Also, 10 mg L−1 polymeric chitosan better triggered total protein production and plant dry matter content in <italic>I. purpurea</italic>. The results of this study showed that, due to their stimulatory effects on photosynthetic pigment, protein and plant dry matter production, chitosan oligomers at low concentration and polymers at moderate concentration might be considered as safe and natural biostimulants for ornamental plants which could affect the plant’s attractiveness and commercial success.</abstract>
