Mechanism and effects of pulsatile GABA secretion from cytosolic pools in the human beta cell

Chiara Cianciaruso, Steinunn Baekkeskov Hanahan, Petra Catalina Schwalie, Edward Allen Phelps

Pancreatic beta cells synthesize and secrete the neurotransmitter GABA (gamma-aminobutyric acid) as a paracrine and autocrine signal to help regulate hormone secretion and islet homeostasis. Islet GABA release has classically been described as a secretory- ...

First-principles calculations of iodine-related point defects in CsPbI3

Joachim Maier, Alessandro Senocrate

We present here first principles hybrid functional calculations of the atomic and electronic structure of several iodine-related point defects in CsPbI3, a material relevant for photovoltaic applications. We show that the presence of neutral interstitial I ...

What is the 'spectral diet' of humans?

Marilyne Andersen, Forrest Simon Webler

Our visual perception of the world - seeing form and colour or navigating the environment - depends on the interaction of light and matter in the environment. Light also has a more fundamental role in regulating rhythms in physiology and behaviour, as well ...

Mechanism suppressing charge recombination at iodine defects in CH3NH3PbI3 by polaron formation

Alfredo Pasquarello, Francesco Ambrosio, Julia Anna Wiktor

Metal-halide perovskites exhibit high efficiencies in photovoltaic applications and low recombination rates, despite the high concentrations of intrinsic defects. We here study the hole trapping at the negative iodine interstitial, which corresponds to the ...
