64 ± 0.36 to 7.06 ± 0.28 μM. In addition, they also effectively decreased VEGF-induced cell migration with IC50 values ranging from 1.57 ± 0.60 to 4.77 ± 0.62 μM. The structure-activity relationship of these compounds is discussed. The anti-angiogenic property of (5R, 8R, 9R, 10R, 13S, 14R, 17R, 18R, 19S)-17,18-epoxy-17,18-seco-28-norlupa-17- hydroxy-20 (29) -ene-3-one is mediated by the VEGFR2 - AKT signaling pathway.Danofloxacin is a fluoroquinolone developed for veterinary medicine and used in avian species for the treatment of numerous bacterial infections. However, no pharmacokinetic data have been reported in geese. The aim of the study was three-fold (i) to evaluate the pharmacokinetics of danofloxacin in geese after single oral (PO) and intravenous (IV) administrations; (ii) to define its residue depletion profile in different goose tissues, and (iii) to recreate a multiple-dose simulation in the practical context of large-scale breeding. Twenty-four healthy geese were randomly divided in three groups each composed of eight animals. Group 1 received danofloxacin IV (5 mg/kg) and groups 2 and 3 were treated PO with the same dose. Blood was collected until 24 h (IV; group 1) and 48 h (PO; group 2) after administration. Two animals from group 3 were sacrificed at 6, 10, 24 and 48 h to collect samples of muscle, heart, kidney, liver, and lung. Danofloxacin was quantified in each matrix using a validated high-performancue penetration value, with an explorative withdrawal time of 2.6 and 3.8 days, respectively. A practical multiple-dose regimen simulation does not lead to significant plasma drug accumulation.

Increasingly, their structurally complex scaffolds are also envisioned as leads for applications for which they did not evolve, an approach aided by engineering of new-to-nature analogs. Ribosomally synthesized and post-translationally modified peptides (RiPPs) are promising candidates for bioengineering because they are genetically encoded and their biosynthetic enzymes display significant substrate tolerance. This review highlights recent advances in the discovery of highly unusual new reactions by genome mining and the application of engineering approaches to generate and screen novel RiPP variants. Furthermore, through the use of synthetic biology approaches, hybrid molecules with enhanced or completely new activities have been identified, which opens the door for future advancement of RiPPs as potential next-generation therapeutics.Amino acids are one of the most important synthons employed in the biotechnology, pharmaceutical and agrochemical industries for the preparation of active agents. Recently, the emerging use of these compounds as tools for protein engineering, has also been reported. Numerous chemo- and biocatalytic strategies have been developed for the stereoselective synthesis of these compounds. One of the most efficient processes is the enzymatic dynamic kinetic resolution of N-acylated derivatives, where an N-acyl amino acid racemase (NAAAR) is coupled with an enantioselective, hydrolytic enzyme (aminoacylase), and used to convert a racemic mixture of starting materials to enantiopure products. Here we provide a brief overview of the structure and mechanism of NAAAR. We will also review the applications of this class of biocatalyst, as well as discussing the various strategies employed to obtain an efficient system for the synthesis of optically pure canonical and non-canonical amino acids.The future availability and quality of natural resources essential to life such as ecosystem services and biodiversity depend on the conservation and restoration of native vegetation. The Brazilian Native Vegetation Protection Law (NVPL) requires farmers to conserve a minimum percentage of native vegetation within their properties as Legal Reserves (LR) as well as riparian forests and hilltops as Permanent Preservation Areas (PPAs). To monitor the conservation and facilitate the compliance of these areas, the Rural Environmental Registry (CAR) and the Environmental Regularization Program (PRA) were created. However, so far, little is known about farmers' interest in joining the PRA and the actions they intend to take to correct their past illegal deforestation. This article explores a unique dataset comprising of the individual answers of 97 thousand farmers in the states of Pará and Mato Grosso given to the Brazilian Forest Service in the process of joining at the national rural environmental registry system. We found that the adherence to the PRA is positively correlated with recognition of the LR deficit and the size of the rural property. Also medium and large landowners and crop producers tend to seek compliance by taking actions outside the farm (compensation), while small farmers and squatters are more likely to act inside their own areas (restoration). Understanding farmers' interests and options for LR compliance can contribute for the formulation of more effective implementation strategies for PRA and NVPL.This paper introduces a new methodology for quantifying the total resilience of water resources management scenarios. The climate change impacts on water supply and demand have been investigated using a calibrated soil and water assessment tool (SWAT) and a MODSIM water allocation model. Several criteria have been defined to measure five aspects of water resources systems resilience. The first aspect defines resilience as system strength against crossing a performance threshold (reliability). read more In the second aspect, if the system crosses the performance threshold, the recovery rate of the system after a disturbance is evaluated. The violation from the performance threshold has been measured as the third aspect (vulnerability), which considers the failure's severity. The fourth aspect is the resilience under extreme events with unknown occurrence probability, which includes four sub-criteria, namely rapidity, robustness, resourcefulness, and redundancy (4 R). Finally, the fifth criterion considers the ecological condition of the system (ecological index). To compare water resources management scenarios (alternatives), an analytical evidential reasoning-based (ER) approach has been used. To show the applicability of the proposed methodology, it has been applied to the Zarrinehrud river basin, which is the leading water supplier of Lake Urmia in Iran. As one of the largest saline lakes globally, this lake has been suffering from drastic desertification and salinization in the past two decades. The grade-based results of the performance criteria are synthesized into a grade-based total resilience criterion to facilitate the comparison of water resources management scenarios. It is shown that a scenario which results in 40% reduction in agricultural water demand until 2023 has the highest resilience and an acceptable construction and operational cost.Land subsidence (LS) in arid and semi-arid areas, such as Iran, is a significant threat to sustainable land management. The purpose of this study is to predict the LS distribution by generating land subsidence susceptibility models (LSSMs) for the Shahroud plain in Iran using three different multi-criteria decision making (MCDM) and five different artificial intelligence (AI) models. The MCDM models we used are the VlseKriterijumska Optimizacija IKompromisno Resenje (VIKOR), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) and Complex Proportional Assessment (COPRAS), and the AI models are the extreme gradient boosting (XGBoost), Cubist, Elasticnet, Bayesian multivariate adaptive regression spline (BMARS) and conditional random forest (Cforest) methods. We used the Receiver Operating Characteristic (ROC) curve, Area Under Curve (AUC) and different statistical indices,i.e. accuracy, sensitivity, specificity, F score, Kappa, Mean Absolute Error (MAE) and Nash-Sutcliffe Criteria (NSC)to validate and evaluate the methods. Based on the different validation techniques, the Cforest method yielded the best results with minimum and maximum values of 0.04 and 0.99, respectively. According to the Cforest model, 30.55% of the study area is extremely vulnerable to land subsidence. The results of our research will be of great help to planners and policy makers in the identification of the most vulnerable regions and the implementation of appropriate development strategies in this area.This study compares the delivered cost of forest biomass and its associated GHG emissions for three sizes of biorefinery including 50,000 m3 (small scale), 250,000 m3 (medium scale), and 700,000 m3 (large scale). The proposed methodology in this study includes harvest intensity which is often overlooked. The Pontiac region located in the Province of Quebec (Southeastern Canada) is used as a case study due to the availability of data in this forestry biomass rich region. Furthermore, there are significant similarities with other forestry regions to enable generalisation of the proposed case study. Harvest intensities of 423 harvest zones (cutblocks) are considered in cost and GHG emissions analysis of delivered biomass from each cutblock to the biorefinery. The results show that harvest intensities of cutblocks must be prioritized over conventional parameters such as transportation distance. The selection and prioritisation of cutblocks according to transportation distance without considering harvest intensities would result in an increase of about 12.5% in delivered costs of biomass for small and medium scale biorefineries. Results also reveal that the transportation distance would be a more significant parameter when using the same harvest intensity for all the selected cutblocks. Required logistics and harvesting equipment for three biorefinery sizes were also quantified. Sensitivity analysis shows that reduced productivity of harvest equipment by 20% could increase the delivered costs of biomass and GHG emissions by 10% for medium and large scale biorefineries and by 13% for a small scale biorefinery.Greenhouse gasses have adverse effects on global warming and air pollution and need to be optimized by minimizing the contributing factors. This work analyzes the effects of economic growth and energy resources (renewable and nonrenewable) on the emissions of greenhouse gasses (GHG). A 2000-2016 panel data from 25 developing Asian countries is analyzed through a robust Random Effect (RE) approach and Hausman Taylor Regression (HTR). Findings show a positive correlation between economic growth and energy consumption, while a 1% increase in renewable energy consumption results in a 0.193% decrease in carbon emissions. Economic growth and renewable energy are positively correlated in both the short and long term, which implies a valid feedback hypothesis. The findings indicate the significant contribution of nonrenewable energy resources to greenhouse gas emissions and the positive impact of renewable resources on greenhouse gas emissions' control. Furthermore, this study highlights the potential of developing Asian economies to preserve the environment through more robust regional environmental policies and renewable energy resources.
