This communication describes a new type of alloyed Cd-In-S quantum dots (CdIS QDs) with ultra small particle size and broadly tunable fluorescence emission from 450 to 700 nm. The band gap of CdIS QDs was mainly controlled by their composition rather than their particle size. The CdIS-ZnS core-shell nanocrystals exhibited ...

The majority of fear conditioning studies in humans have focused on fear acquisition rather than fear extinction. For this reason only a few functional imaging studies on fear extinction are available. A large number of animal studies indicate the medial prefrontal cortex (mPFC) as neuronal substrate of extinction. We therefore ...

Abstract Objectives: Motion sickness (MS) is evoked by the conflict among somatosensory, visual, and vestibular input. Some of the MS symptoms and signs are mediated by activation of the autonomic nervous system (ANS). Transcutaneous electrical nerve stimulation (TENS), a maneuver used for pain control, was found to influence cardiovascular responses ...

The drastically different reactivity of the retinal chromophore in solution compared to the protein is poorly understood. Here, we show that the addition of a methyl group to the C=C backbone of all-trans retinal protonated Schiff base accelerates the electronic decay in solution making it comparable to the proton pump ...

FGF receptor 1 (FGFR1), a membrane-targeted protein, is also involved in independent direct nuclear signalling. We show that nuclear accumulation of FGFR1 is a common response to retinoic acid (RA) in pluripotent embryonic stem cells (ESC) and neural progenitors and is both necessary and sufficient for neuronal-like differentiation and accompanying ...

Self-assembly is a desired property in supramolecular chemistry, but extensive aggregation may be counterproductive. Rigid systems typically have better organization, but are inherently less dynamic. This work shows that ion transport by amphiphilic heptapeptides (synthetic anion transporters or SATs) is affected by aggregation of the monomers in the bulk aqueous ...

Sticky stuff: A versatile strategy to spatially control gene expressions of mammalian cells is developed. A catecholamine polymer (PEI-C) is used to functionalize surfaces of adeno-associated viruses (AAV). Because of the underwater adhesive property of catechol, AAV/PEI-C hybrid vectors become highly "sticky", resulting in spatially patterned viral attachment onto substrates ...
