Adiponectin, an adipocyte-derived protein, has been suggested to play important role in insulin sensitivity. We examined the association between sensitivity (M value) evaluated by euglycemic-hyperinsulinemic glucose clamp and adiponectin concentrations 30 essential hypertensives (EHT) 20 normotensives (NT) investigated effect of blockade renin-angiotensin system (RAS) on concentrations. EHT were divided into 12 insulin-resistant (EHT-R) 18 non-insulin-resistant (EHT-N) using mean-1 SD M...
This article presents the high temperature tensile and creep behaviors of a novel entropy alloy (HEA). The microstructure this HEA resembles that advanced superalloys with FCC matrix L1
The present work investigates the high temperature oxidation and corrosion behaviour of entropy superalloys (HESA). A content various solutes in HESA leads to formation complex oxides, however Cr Al activities are sufficient promote protective chromia or alumina on surface. By comparing resistances a Ni-based superalloy—CM247LC, Al2O3-forming can possess comparable resistance at 1100 °C, Cr2O3-forming exhibit superior against hot 900 °C. This has demonstrated potential maintain surface...
Although refractory high entropy alloys (RHEAs) have shown potentials to be developed as structural materials for elevated temperature applications, most of the reported oxidation behaviours RHEA were associated with short term exposures only up 48 hours, and there is a lack understanding on mechanism any to-date. In this work, by using thermogravimetric analysis, isothermal was conducted novel at 1000 °C 1100 200 which an unprecedented testing duration. The external oxide layer strongly...
Based on results of in vitro studies, it has been hypothesized that blockade the renin-angiotensin system (RAS) promotes recruitment and differentiation pre-adipocytes increased formation small insulin-sensitive adipocytes counteracts ectopic deposition lipids, thereby improving insulin sensitivity. We investigated effect RAS sensitivity, adipocyte size, intramuscular lipid content fructose-fed rats (FFR) as a model insulin-resistant hypertension.Six-week-old male Sprague-Dawley were divided...
Thermal barrier coatings (TBCs) with different levels of segmentation crack density were produced by spraying two types ZrO 2 –8Y O 3 powders. The fused and crushed powder has a greater capability forming segmented than the hollow sphere (HOSP) one. highly reveal much lower porosity compared traditionally sprayed coatings, thereby compromising property thermal insulation TBCs. Microstructure conductivity HOSP are more sensitive to changes in spray conditions. Segmentation cracks had strong...
Our previous study showed that kallikrein gene transfer protects against gentamicin-induced nephrotoxicity and enhances renal function. In this study, we investigated the effects potential mechanisms of kallikrein/kinin on inflammation apoptosis induced by gentamicin.Rats were injected subcutaneously with gentamicin daily for 10 days received an intravenous injection adenovirus carrying human tissue or control virus first day administration.After treatment, significantly attenuated tubular...
Novel high temperature alloys – entropy superalloys (HESA) have been developed by elevating the mixing entropies of Ni-Al-Co-Cr-Fe-Ti systems, these contain stable FCC γ matrix and L12 γ' precipitates; compositions spaces are outside scopes traditional Ni-base equimolar alloys. The thermal stability precipitates can be enhanced through alloy design thermodynamic calculation based on Thermo-Calc. HESAs potentials to structural application; densities below 8.0 g/cm3 with lower cost raw...
The microstructure and high temperature hardness of two face‐centered cubic entropy Ni‐based alloys with L1 2 γ′ precipitates have been studied. Both exhibit higher mixing the advantages in lower density cost raw materials than conventional superalloys. Their solvus are above 1 150 °C, γ–γ′ can be thermodynamically stable after isothermal ageing from 700 to 100 °C for at least 500 h. By XRD peak deconvolution, positive lattice misfits between γ shown till elevated temperatures. results...
Shape memory effect, the ability to recover a pre-deformed shape on heating, results from reversible martensitic transformation between austenite and martensite phases. Here, we demonstrate strategy of designing high-entropy alloys (HEAs) with high-temperature effect in CrMnFeCoNi alloy system. First, calculate difference Gibbs free energy face-centered-cubic (FCC) hexagonal-close-packed (HCP) phases, find substantial increase thermodynamic equilibrium temperature FCC HCP phases through...

Design methods Six-week-old male Sprague-Dawley rats were fed either normal rat chow or fructose-rich chow. For last 2 weeks a 6-week period diet, treated with vehicle (control FFR); temocapril, an angiotensin converting...
LaB6 nanowires are ideal for applications as an electrical field-induced ion and electron point source due to their miniature dimensions, low work function, well excellent electrical, thermal, mechanical properties. We present here a reliable method fabricate assemble single nanowire-based field emitters of different crystal orientations. The atomic arrangement, emission brightness from each plane, stability have been characterized using microscopy (FIM) (FEM). It is found that the ⟨001⟩...
Abstract A hierarchical microstructure strengthened high entropy superalloy (HESA) with superior cost specific yield strength from room temperature up to 1,023 K is presented. By phase transformation pathway through metastability, HESA possesses a containing dispersion of nano size disordered FCC particles inside ordered L1 2 precipitates that are within the matrix. The average tensile could be 120 MPa higher than advanced single crystal superalloy, while still exhibit an elongation greater...
