Construction of Multifunctional Nanoarchitectures in One Step on a Composite Fuel Catalyst through In Situ Exsolution of LaSrFeNiNbO.

Multifunctional nanoarchitecture (MNA) on catalysts has attracted great attention because of its capability to improve the performance, durability, and resistance to unwanted side reactions. Such structures, however, are conventionally prepared by deposition methods, which inherently suffer from costly and time-consuming drawbacks. Here, we report a simple one-step process to successfully construct a novel MNA with core-shell nanoparticles anchored at the heterointerface of dual-phase oxide substrates through a phase transition and in situ exsolution of perovskite LaSrFeNiNbO (LSFNNb0.

A self-assembled dual-phase composite as a precursor of high-performance anodes for intermediate temperature solid oxide fuel cells.

A durable high-performance anode with a unique microstructure of a hetero-structured surface layer and exsolved Fe-Cu bimetal nano-fibers is fabricated from a self-assembled dual-phase precursor consisting of a single perovskite (SP) and a Ruddlesden-Popper (RP) layered perovskite component. This work opens up new opportunities to fabricate high-performance anodes for IT-SOFCs.

Vagal Modulation of the Inflammatory Response in Sepsis.

The vagus nerve can sense peripheral inflammation and transmit action potentials from the periphery to the brainstem. Vagal afferent signaling is integrated in the brainstem, and efferent vagus nerves carry outbound signals that terminate in spleen and other organs. Stimulation of efferent vagus nerve leads to the release of acetylcholine in these organs.

Novel Nano-composites SDC-LiNaSO as Functional Layer for ITSOFC.

As an ionic conductive functional layer of intermediate temperature solid oxide fuel cells (ITSOFC), samarium-doped ceria (SDC)-LiNaSO nano-composites were synthesized by a sol-gel method and their properties were investigated. It was found that the content of LiNaSO strongly affected the crystal phase, defect concentration, and conductivity of the composites. When the content of LiNaSO was 20 wt%, the highest conductivity of the composite was found to be, respectively, 0.

Internal and external carotid artery embolism following facial injection of autologous fat.

Autologous fat injection is a common aesthetic procedure for soft-tissue augmentation of the face. Although this procedure is generally regarded as safe, several patients have experienced acute visual loss or cerebral infarction after these injections. We describe a case of internal and external carotid artery fat embolism that occurred following injection of autologous fat into the face.

Advances in the management of acute liver failure.

Acute liver failure (ALF) is an uncommon but dramatic clinical syndrome characterized by hepatic encephalopathy and a bleeding tendency due to abrupt loss of liver function caused by massive or submassive liver necrosis in a patient with a previously healthy liver. The causes of ALF encompass a wide variety of toxic, viral, metabolic, vascular and autoimmune insults to the liver, and identifying the correct cause can be difficult or even impossible. Many patients with ALF develop a cascade of serious complications involving almost every organ system, and death is mostly due to multi-organ failure, hemorrhage, infection, and intracranial hypertension.

Stimulation of α7 nicotinic acetylcholine receptor by nicotine increases suppressive capacity of naturally occurring CD4+CD25+ regulatory T cells in mice in vitro.

α7 Nicotinic acetylcholine receptor (α7 nAChR) has been found in several non-neuronal cells and is described as an important regulator of cellular function. Naturally occurring CD4(+)CD25(+) regulatory T cells (Tregs) are essential for the active suppression of autoimmunity. The present study investigated whether naturally occurring Tregs expressed α7 nAChR and investigated the functionary role of this receptor in controlling suppressive activity of these cells.
