Guidelines on sustainable forest management in drylands of Ethiopia [PDF]

open access: yes, 2019
About 80% of forests in Ethiopia are dry forest. For the last 20 years they have been subject to land use changes, and replaced by agricultural land and settlements.

Separation Options for Phosphorylated Osteopontin from Transgenic Microalgae Chlamydomonas reinhardtii. [PDF]

open access: yes, 2018
Correct folding and post-translational modifications are vital for therapeutic proteins to elicit their biological functions. Osteopontin (OPN), a bone regenerative protein present in a range of mammalian cells, is an acidic phosphoprotein with multiple ...

Unveiling unique protein and phosphorylation signatures in lung adenocarcinomas with and without ALK, EGFR, and KRAS genetic alterations

open access: yesMolecular Oncology, EarlyView.
Proteomic and phosphoproteomic analyses were performed on lung adenocarcinoma (LUAD) tumors with EGFR, KRAS, or EML4–ALK alterations and wild‐type cases. Distinct protein expression and phosphorylation patterns were identified, especially in EGFR‐mutated tumors. Key altered pathways included vesicle transport and RNA splicing.

Development of Polymer Resins using Neural Networks

open access: yesPolímeros, 2002
The development of polymer resins can benefit from the application of neural networks, using its great ability to correlate inputs and outputs. In this work we have developed a procedure that uses neural networks to correlate the end-user properties of a

Nicotinamide N‐methyltransferase promotes drug resistance in lung cancer, as revealed by nascent proteomic profiling

open access: yesMolecular Oncology, EarlyView.
AZD9291 has shown promise in targeted cancer therapy but is limited by resistance. In this study, we employed metabolic labeling and LC–MS/MS to profile time‐resolved nascent protein perturbations, allowing dynamic tracking of drug‐responsive proteins. We demonstrated that increased NNMT expression is associated with drug resistance, highlighting NNMT ...

Studies of the biological and therapeutic effects of argentine stingless bee propolis [PDF]

open access: yes, 2018
Meliponids are native bees of the Americas, characterized by having no sting (ANSA). Some live in the Yunga forests of northern Argentina, a place rich in a diversity of this type of bees of which at least thirty-three species may be found. Propolis is a

Biophysical characterization and ion transport with cell‐based and proteoliposome reconstitution assays of invertebrate K+‐Cl− cotransporters

open access: yesFEBS Open Bio, EarlyView.
The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Experimental kinetic study of transesterification of ethyl acetate with methanol catalyzed by gel and macroporous acidic ion exchange resins [PDF]

open access: yes, 2012
The reaction kinetics of the liquid-phase transesterification of ethyl acetate with methanol have been investigated over a series of commercially available ion-exchange resins. Two morphology types of cross-linked polymer resins have been considered, i.e.
