Biosynthesis of scopoletin and scopolin in cassava roots during post-harvest physiological deterioration
Two to three days after harvesting, cassava (Manihot esculenta Crantz) roots suffer from post-harvest physiological deterioration (PPD) when secondary metabolites are accumulated. Amongst these are hydroxycoumarins (e.g....

Topical formulation and dermal delivery of active phenolic compounds in the Thai medicinal plant - <em>Clerodendrum</em> <em>petasites</em> S. Moore

Purpose: To develop topical formulations of Clerodendrum petasites S. Moore (CP), and to optimize the skin permeability and topical bioavailability of the active phenolic compounds therein. Methods: The skin...

Rigid analytic quantum groups and quantum Arens-Michael envelopes
Nicolas Dupré
Aug 19, 2019
We introduce a rigid analytification of the quantized coordinate algebra of a semisimple algebraic group and a quantized Arens-Michael envelope of the enveloping algebra of the corresponding Lie algebra, working over a...
Organocatalytic Enantioselective Sulfa-Michael Additions to α,β-Unsaturated Diazoketones

Enantioselective sulfa-Michael additions to α,β unsaturated diazocarbonyl compounds have been developed. Quinine-derived squaramide was found to be the best catalyst to promote C-S bond formation in a highly stereoselective...

G-Quadruplexes
Guanine (G)-rich sequences in nucleic acids can assemble into G-quadruplex structures that involve G-quartets linked by loop nucleotides. The structural and topological diversity of G-quadruplexes have attracted great attention...
Structural basis of G-quadruplex unfolding by the DEAH/RHA helicase DHX36.
Guanine-rich nucleic acid sequences challenge the replication, transcription, and translation machinery by spontaneously folding into G-quadruplexes, the unfolding of which requires forces greater than most polymerases can...
Review of: Karen Hunger Parshall, Michael T. Walton and Bruce T. Moran (eds.), Bridging Traditions
S Fransen
Mar 04, 2019
This collected volume is written in honour of Allen G. Debus (1926–2009), the famous historian of science. Trained as a chemist, his interest in the history of science and chemistry would guide his research and his output. As...
Synthesis of Novel Regenerable 13X Zeolite-Polyimide Adsorbent Foams

A new generic synthesis method is presented for the production of a polyimide (PI)/adsorbent (80 wt% 13X zeolite) regenerable foam filter. The method uses a dual parallel reaction foaming process comprising CO 2...

Remote stereocontrol in [3,3]-sigmatropic rearrangements
The Ireland - Claisen [3,3]-sigmatropic rearrangement has been used to access biologically important β,β′-dihydroxy α-amino acids. The rearrangement reported is highly stereoselective and offers excellent levels of remote...
RNA promotes phase separation of glycolysis enzymes into yeast G bodies in hypoxia.
In hypoxic stress conditions, glycolysis enzymes assemble into singular cytoplasmic granules called glycolytic (G) bodies. G body formation in yeast correlates with increased glucose consumption and cell survival. However, the...
Density Functional Theory Transition-State Modeling for the Prediction of Ames Mutagenicity in 1,4 Michael Acceptors

Assessing the safety of new chemicals, without introducing the need for animal testing, is a task of great importance. The Ames test, a widely used bioassay to assess mutagenicity, can be an expensive, wasteful process with...

Modelling and simulation of biased agonism dynamics at a G protein-coupled receptor.
Theoretical models of G protein-coupled receptor (GPCR) concentration-response relationships often assume an agonist producing a single functional response via a single active state of the receptor. These models have largely...

Assessment Of The MODU Rowan Gorilla I Capsize And Sinking
Darren Hickey
Apr 09, 2013
The Rowan Gorilla I was a Mobile Offshore Drilling Unit (MODU) fabricated in Mississippi by the Marathon Le Tourneau Shipyard, and completed in 1983. The jack-up spent its first 5 years following completion off the east coast...
