Development and characterisation of monolithic silica stationary phases for ion chromatography [PDF]

open access: yes, 2006
Silica based monolithic HPLC columns have received much attention in recent years, particularly those modified for reversed-phase separations. However, for ionexchange, silica based monolithic columns have received only limited attention.

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC [PDF]

open access: yes, 2012
Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways.

A Single Biaryl Monophosphine Ligand Motif—The Multiverse of Coordination Modes

open access: yesInorganics, 2023
Biaryl monophosphines are important precursors to active catalysts of palladium-mediated cross-coupling reactions. The efficiency of the phosphine-based transition metal complex catalyst has its origin in the electronic structure of the complex used and ...

The fabrication and modification of capillary polymer monoliths for the separation of small ions [PDF]

open access: yes, 2012
The fabrication and modification of polymer monoliths, in capillary formats, for the separation of small ions is presented. The separation of small ions using polymer monoliths has limitations and this work aims to investigate increasing the ion exchange

Measurements of cadmium levels in relation to tobacco dependence and as a function of cytisine administration

open access: yesScientific Reports
Cigarette smoking delivers a number of heavy metals, including cadmium (Cd), into the body. Bioaccumulation may result in an increase in pathological consequences over time.

Major Inorganic Ions in Polish Beers

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Food Science and Technology, 2021
Reliable determination of various components of beers is still a challenge due to their complex matrices. Inorganic ions are very important components of beer; their content depends mainly on the quality of water and additional substances used in the ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
