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

, 2008 Self-referencing with ion-selective microelectrodes (ISMs) is a useful approach for monitoring near-real-time ion flux near single cells and across epithelia. While ISMs for H+, Ca2+, and K+ have been optimized for use with self-referencing, ISMs for two

Modulation of ion uptake in tomato (Lycopersicon esculentum L.) plants with exogenous application of calcium under salt stress condition [PDF]
Poljoprivreda, 2016 Salinity affects almost every aspect of the physiology and biochemistry of plants due to both osmotic stress and ionic toxicity. We studied the variation of ion uptake in tomato cv.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Ion Selectivity and Allostery in the NaK Channel [PDF]
, 2015 Ion channels require proper ion selectivity and regulated gating in order to perform their cellular functions. Bacterial ion channels serve as excellent model systems to study structure/function relationships concerning the fundamental processes of ion ...

Ion–Ion Interactions at the Selectivity Filter [PDF]
The Journal of General Physiology, 2000 In the Kv2.1 potassium channel, binding of K+ to a high-affinity site associated with the selectivity filter modulates channel sensitivity to external TEA. In channels carrying Na+ current, K+ interacts with the TEA modulation site at concentrations ≤30 μM.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.
