Screening the Pathogen Box for Identification of New Chemical Agents with Anti-Fasciola hepatica Activity
(American Society for Microbiology, 2019)
Fascioliasis is an infectious parasitic disease distributed globally and caused by the liver fluke Fasciola hepatica or F. gigantica This neglected tropical disease affects both animals and humans, and it represents a ...
Active thermo chemical tables: thermochemistry for the 21st century
(2005-12)
Active Thermochemical Tables (ATcT) are a good example of a significant breakthrough in chemical science that is directly enabled by the US DOE SciDAC initiative. ATcT is a new paradigm of how to obtain accurate, reliable, ...
Enzymatic and chemical synthesis of new anticoagulant peptides
(American Chemical Society, 2018-09)
In this study we report the enzymatic synthesis of N-α-[Carbobenzyloxy]-Tyr-Gln-Gln (Z-YQQ), a new anticoagulant tripeptide. It was obtained using phytoproteases from the stems and petioles of Asclepias curassavica L. as ...
Chemical derivatization of natural extracts obtained from Larrea divaricata Cav. increase in the antioxidant activity and protein precipitating capacity
(Academia Publishing, 2017-07)
In the present work modified extracts of Larrea divaricata was obtained bychemical transformations in order to improve the antioxidant activity and theprotein precipitating capacity. Apigenine-7-methylether, quercetin, ...
Highly microporous sorbents from lignocellulosic biomass: Different activation routes and their application to dyes adsorption
(Elsevier, 2019-10)
Highly microporous carbons were produced from two abundant agricultural residues, olive tree pruning and coffee husk. Different activation routes were tested to obtain the adsorbents, choosing experimental conditions that ...
Isolation, chemical investigation and antiviral activity of polysaccharides from Gracilaria corticata (Gracilariaceae, Rhodophyta)
(Elsevier Science, 2002-12)
Polysaccharides were sequentially extracted from the agarophyte Gracilaria corticata. Chemical analysis combined with infrared spectroscopy showed that the cold water extracted material consists mainly of a high molecular ...
Chemical effects on dye efflux activity in live zebrafish embryos and on zebrafish Abcb4 ATPase activity
(Elsevier Science, 2020-12)
ATP‐binding cassette (ABC) transporter proteins include efflux pumps that confer multixenobiotic resistance to zebrafish embryos, a valuable toxico/pharmacological model. Here, we established an automated microscopy‐based ...
Understanding Chemical Equilibrium: The Role of Gas Phases and Mixing Contributions in the Minimum of Free Energy Plots
(American Chemical Society, 2017-03)
The use of free energy plots to understand the concept of thermodynamic equilibrium has been shown to be of great pedagogical value in materials science. Although chemical equilibrium is also amenable to this kind of ...
Production process optimization model to increase productivity of microenterprises in the industrial chemical sector using 5s and tpm
(Springer, 2021-01-01)
The industrial chemical sector has grown during the last years in the Peruvian market, becoming highly competitive since it represents the second main activity in the manufacturing industry. However, companies belonging ...
