Signal Transduction and Pathogenic Modifications at the Melanocortin-4 Receptor: A Structural Perspective [PDF]

open access: yes, 2019
The melanocortin-4 receptor (MC4R) can be endogenously activated by binding of melanocyte-stimulating hormones (MSH), which mediates anorexigenic effects. In contrast, the agouti-related peptide (AgRP) acts as an endogenous inverse agonist and suppresses

Synthetic Lignin Oligomers: Analytical Techniques, Challenges, and Opportunities

open access: yesChemSusChem, EarlyView.
The review begins by discussing lignin and its structural complexity, followed by challenges in elucidating depolymerization products and the analytical techniques used. It then focuses on the chemical structure of synthetic lignin oligomers, their synthesis mechanisms, and their significance in current science. Finally, scientific gaps are identified,

G-Protein coupled receptor signalling in pluripotent stem cell-derived cardiovascular cells: Implications for disease modelling [PDF]

open access: yes, 2015
Human pluripotent stem cell derivatives show promise as an in vitro platform to study a range of human cardiovascular diseases. A better understanding of the biology of stem cells and their cardiovascular derivatives will help to understand the strengths

Simulations of Incompressible MHD Turbulence [PDF]

open access: yes, 2000
We simulate incompressible MHD turbulence in the presence of a strong background magnetic field. Our major conclusions are: 1) MHD turbulence is most conveniently described in terms of counter propagating shear Alfven and slow waves. Shear Alfven waves control the cascade dynamics.

Enzymatic Treatment of Lignin in Alkaline Homogeneous Systems: A Review on Alkaliphilic Laccases

open access: yesChemSusChem, EarlyView.
This review summarizes the enzymatic treatment of lignin in alkaline homogeneous systems, with a focus on alkaliphilic laccases. Unlike native laccases that promote lignin polymerization under acidic conditions, these enzymes work in basic pH, where industrial lignins are soluble.

Evolvability of Chaperonin Substrate Proteins [PDF]

open access: yes, 2009
Molecular chaperones ensure that their substrate proteins reach the functional native state, and prevent their aggregation. Recently, an additional function was proposed for molecular chaperones: they serve as buffers (_capacitors_) for evolution by ...

Comparative analysis of two genomic regions among four strains of Buchnera aphidicola, primary endosymbiont of aphids.

open access: yes, 2004
Preliminary analysis of two selected genomic regions of Buchnera aphidicola BCc, the primary endosymbiont of the cedar aphid Cinara cedri, has revealed a number of interesting features when compared with the corresponding homologous regions of the three ...
