Spontaneous coronary artery dissection during cisplatin and capecitabine therapy.

Introduction: Spontaneous coronary artery dissection is a rare cardiovascular disease that can cause acute myocardial infarction and sudden cardiac death. The mechanism of this pathology and the optimal treatment are not fully understood.

Presentation Of Case: An acute myocardial infarction developed while a fifty five years old woman with a rectal adenocarcinoma was receiving a cisplatin and capecitabine therapy.

Electronic transport via proteins.

A central vision in molecular electronics is the creation of devices with functional molecular components that may provide unique properties. Proteins are attractive candidates for this purpose, as they have specific physical (optical, electrical) and chemical (selective binding, self-assembly) functions and offer a myriad of possibilities for (bio-)chemical modification. This Progress Report focuses on proteins as potential building components for future bioelectronic devices as they are quite efficient electronic conductors, compared with saturated organic molecules.

Nanoscale electron transport and photodynamics enhancement in lipid-depleted bacteriorhodopsin monomers.

Potential future use of bacteriorhodopsin (bR) as a solid-state electron transport (ETp) material requires the highest possible active protein concentration. To that end we prepared stable monolayers of protein-enriched bR on a conducting HOPG substrate by lipid depletion of the native bR. The ETp properties of this construct were then investigated using conducting probe atomic force microscopy at low bias, both in the ground dark state and in the M-like intermediate configuration, formed upon excitation by green light.

Large anisotropic conductance and band gap fluctuations in nearly round-shape bismuth nanoparticles.

Unlike their bulk counterpart, nanoparticles often show spontaneous fluctuations in their crystal structure at constant temperature [Iijima, S.; Ichihashi T. Phys.

Very high thermopower of Bi nanowires with embedded quantum point contacts.

Quantum confinement effects in bismuth (Bi) nanowires (NWs) are predicted to impart them with high thermopower values and hence make them efficient thermoelectric materials. Yet, boundary scattering of charge carriers in these NWs operating in the diffusion transport regime mask any quantum effects and impede their use for nanoscale thermoelectric applications. Here we demonstrate quantum confinement effects in Bi NWs by forming in their structure ballistic quantum point contacts (QPCs) leading to exceptionally high thermopower values (S > 2 mV/K).
