It is common knowledge that adaptation to hypobaric hypoxia provides for a number of protective NO-dependent effects in the organism. However, many aspects of its influence on NO metabolism remain unclear. In this work we studied the relationship between NO production and deposition in the course of adaptation to hypoxia. No production was assayed by the total concentration of nitrates and nitrites in rat serum, while the volume of NO depot was determined from the level of isolated aorta relaxation in response to diethyldithiocarbamate in vitro. In the course of adaptation to hypoxia, nitrate and nitrite concentration increases as well as NO deposition in the vascular wall. The volume of NO depot correlated reliably with the serum concentration of nitrates and nitrites. Hence, adaptation to hypoxia increases NO production and deposition, which can underlie its NO-dependent protective effects.

The present study demonstrates the synthesis of compact ZnO layers using CdS sensitized on ZnO as a photoanode with copper sulfide (CuS) and carbon as a counter electrode (CE). In this study, a compact ZnO layer was fabricated using the simple and low-cost successive ionic layer adsorption and reaction (SILAR) method, and CuS CE films were synthesized using the chemical bath deposition method. Various characterizations, such as X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), confirmed the formation of ZnO and CdS sensitizations on the ZnO .

Zn-air batteries (ZABs) present high energy density and high safety but suffer from low oxygen reaction reversibility and dendrite growth at Zn electrode in alkaline electrolytes. Non-alkaline electrolytes have been considered recently for improving the interfacial processes in ZABs. However, the dynamic evolution and reaction mechanisms regulated by electrolytes at both the positive and Zn negative electrodes remain elusive.

In this study we evaluated the effects of flow lamination on aerosol flow dynamics and deposition at the exit point in testing models with spatial barriers (narrowing or curving).We compared ModiFlow (MF) to an idealized Standard Spacer (SS) in their efficiency of delivery of aerosolized medication (fluticasone) across different types of spatial barriers. Fluticasone propionate HFA Inhaler from Prasco Labs 220 µg per actuation was used to deliver 1 spray in each test tube.

Flexibility enhancement is a pressing issue in the current development of advanced lithium-metal battery applications. Many types of organic polymers are inherently flexible, which can form a composite structure enhancing electrode flexibility. However, organic polymers have a negative influence on the plating and stripping of lithium-metal anodes, and the large number of polymers block the pore of the material, reducing the utilization of the active site.

This study reports a rare case of immune-complex mediated mesangial proliferative glomerulonephritis (ICGN) with a full-house pattern in a 56-year-old Japanese man, observed during the treatment of immune thrombocytopenic purpura (ITP). Because of persistent complement deficiency and worsening of kidney function, he was treated with prednisolone, and his urinary findings improved markedly. However, as the complement titers were still low, mycophenolate mofetil was also prescribed, which normalized complement levels.
