Soft matter, 11(29), 5883-5888 (2015-06-25)
Solid surfaces suspended in critical aqueous binary mixtures containing hydrophilic salt have recently been found to exhibit anomalous interactions, and a possible mechanism is provided by the asymmetric solvation preferences of weakly and strongly hydrophilic cations and anions, respectively. Here...

Previous research demonstrated that sperm motility is dependent upon mitochondrial calcium cycling. Thus, sperm are inactivated when extracellular calcium ions are chelated. Mitochondrial calcium cycling, however, is driven by extracellular sodium ions. The hypothesis that sperm inactivation is subject to...

Human embryonic stem cells (hESCs) are pluripotent and capable of generating new β-cells, but current in vitro differentiation protocols generally fail to produce mature, glucose-responsive, unihormonal β-cells. Instead, these methods tend to produce immature polyhormonal endocrine cells which mature in...

Bacteria communicate with each other by the use of signaling molecules, a process called 'quorum sensing'. One group of quorum sensing molecules includes the oligopeptides, which are mainly produced by Gram-positive bacteria. Recently, these quorum sensing peptides were found to...

Friedreich's ataxia (FA) is a recessive, predominantly neurodegenerative disorder caused in most cases by mutations in the first intron of the frataxin (FXN) gene. This mutation drives the expansion of a homozygous GAA repeat that results in decreased levels of...

Transplantation is one potential clinical application of neural stem cells (NSCs). However, it is very difficult to monitor/control NSCs after transplantation and so provide effective treatment. Electrical measurement using a poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) modified microelectrode array (MEA) is a biocompatible, non-invasive...

We study the addition of electrolytes to surfactant-free microemulsions in the domain where polydisperse pre-Ouzo aggregates are present. As in previous studies, the microemulsion is the ternary system water/ethanol/1-octanol, where ethanol acts as co-solvent. Addition of electrolytes modifies the static...
