Inducible arginase 1 deficiency in mice leads to hyperargininemia and altered amino acid metabolism [PDF]

open access: yes, 2013
Arginase deficiency is a rare autosomal recessive disorder resulting from a loss of the liver arginase isoform, arginase 1 (ARG1), which is the final step in the urea cycle for detoxifying ammonia. ARG1 deficiency leads to hyperargininemia, characterized

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Climate effects of recycled fertilizers and biochar: emissions of nitrous oxide, methane and ammonia in a field experiment [PDF]

open access: yes, 2018
Background Nitrogen (N) fertilizers are essential for crop production. Farmyard manure and slurry traditionally constitute about half of the total N inputs into crop production in Switzerland.

Machine Learning‐Enabled Polymer Discovery for Enhanced Pulmonary siRNA Delivery

open access: yesAdvanced Functional Materials, EarlyView.
This study provides an efficient approach to train a machine learning model by merging heterogeneous literature data to predict suitable polymers for siRNA delivery. Without the need for extensive laboratory synthesis, the machine learning enabled a virtual screening and successfully predicted a polymer that is validated for effective gene silencing in

REGIONAL DIFFERENTIATION AND POSSIBILITIES OF REDUCING AMMONIA EMISSIONS FROM AGRICULTURE IN POLAND [PDF]

open access: yesAnnals of the Polish Association of Agricultural and Agribusiness Economists, 2019
The main purpose of this paper was to present ammonia (NH3) emissions from agriculture, on a regional scale, in 2017, and identify recommendable agricultural practices limiting ammonia emissions.

Natural Gas as Feedstock for Fertilizer [PDF]

open access: yes, 2007
Separation of the hydrogen needed for the ammonia synthesis reaction, from its source is difficult. Hydrogen production method is the main source of distinction between the various ammonia production routes.

Biochemistry Changes That Occur after Death: Potential Markers for Determining Post-Mortem Interval [PDF]

open access: yes, 2013
Death is likely to result in very extensive biochemical changes in all body tissues due to lack of circulating oxygen, altered enzymatic reactions, cellular degradation, and cessation of anabolic production of metabolites.
