Comparison of Dried Blood Spot Sampling Methods for RNA‐Based Biomarker Measurement in Anti‐Doping

open access: yesDrug Testing and Analysis, EarlyView.
This study demonstrates that RNA‐based biomarkers of erythropoiesis, ALAS2 and CA1, can be reliably quantified across commonly used DBS sampling matrices, including venous and capillary blood spotted on cellulose cards and the Tasso‐M20 device. ABSTRACT Dried blood spot (DBS) sampling offers logistical advantages, but it remains unexplored whether ...

Modified Guanidines as Potential Chiral Superbases. 3. Preparation of 1,4,6-Triazabicyclooctene Systems and 1,4-Disubstituted 2-Iminoimidazolidines by the 2-Chloro-1,3-dimethylimidazolinium Chloride-Induced Cyclization of Guanidines with a Hydroxyethyl Substituent

open access: yes, 2016
Simple preparation methods of modified guanidines have been explored as potential chiral superbases. Thus, 3,7,8-trisubstituted and 3,6,7,8-tetrasubstituted 1,4,6-triazabicyclooctene systems were prepared from (1S,2S)-1,2-diphenylethylenediamine through ...

Titanacarborane Amide Catalyzed Transamination of Guanidines

open access: yes, 2016
This work describes a catalytic transamination of guanidines with a broad substrate scope of primary, secondary, heterocyclic, aliphatic, and aromatic amines, using 5−10 mol % of the half-sandwich titanacarborane amide [σ:η1:η5-(OCH2)(Me2NCH2)C2B9H9]Ti ...

The role of Rho GTPases in facial morphogenesis

open access: yesDevelopmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Ion‐Enriched Porous Organic Polymer for Gold Recovery From E‐Waste

open access: yesEcoEnergy, EarlyView.
A novel ion‐enriched porous organic polymer was designed and synthesized. It exhibits ultrahigh gold adsorption efficiency with capacity up to 1530.9 mg g−1, and also shows selective capture ability towards gold ions in the actual CPU leaching solution, demonstrating its promising potential for gold recovery from actual e‐waste.

Copper-catalyzed oxidative three-component synthesis of N, N',N″-trisubstituted guanidines.

open access: yes, 2013
International audienceA copper-catalyzed three-component synthesis of trisubstituted N-aryl guanidines involving cyanamides, arylboronic acids, and amines has been developed. This operationally simple oxidative process, which is performed in the presence

Optimized iCIEF Fractionation Enables Deep Profiling of Antibody Drug Conjugate Charge Heterogeneity

open access: yesELECTROPHORESIS, EarlyView.
This study developed and optimized an iCIEF fractionation method to characterize ADC charge variants. The optimized approach enabled stable separation, identification of major PTMs, and drug‐load distributions across light and heavy chains. ABSTRACT Antibody drug conjugates (ADCs) are a novel class of therapeutic drugs that combine selectivity of an ...

Proteomic signatures of equine dental tooth tissues in ageing and disease

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...
