Charge Imbalance

open access: yes, 1981
The purpose of this article is to review the theory of charge imbalance, and to discuss its relevance to a number of experimental situations. We introduce the concepts of quasiparticle charge and charge imbalance, and discuss the generation and detection of charge imbalance by tunneling.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Role of Th1/Th2 imbalance mediated by T cell glycolytic rate-limiting enzymes hexokinase 2, phosphofructokinase-1, and pyruvate kinase M2 in oral lichen planus

open access: yesRomanian Journal of Laboratory Medicine
We aimed to explore the role of T helper cell 1 (Th1)/Th2 imbalance mediated by T cell glycolytic rate-limiting enzymes hexokinase 2 (HK2), phosphofructokinase-1 (PEK1) and pyruvate kinase M2 (PKM2) in oral lichen planus (OLP).

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Lipopolysaccharide-binding systems in the pathogenesis of vascular complications in patients with type 1 diabetes mellitus

open access: yesActa Biomedica Scientifica
Rationale. Disturbance of glycemia in type 1 diabetes mellitus (DM1) leads to the development of oxidative stress and damage to the barrier organs for lipopolysaccharide (LPS), which is accompanied by its increased translocation into the systemic ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Urban hierarchy and spatial interaction in the regional urban system in Dobrogea, Romania

open access: yesRevija za Geografijo
A region has a certain area within which there is a certain number of cities that are different in the number of the inhabitants, located at different distances from each other, forming an urban system that is based on the multitude of relationships ...
