A new concept for producing highly pure Ti metal powder from ilmenite(FeTiO)_(3))is proposed in this *** nitride(TiN)or titanium oxycarbonitride(TiO_(x)C_(y)N_(z))could be synthesized in the first step via the simultaneous carbothermal reduction and nitridation(CTRN)of FeTiO3 to remove oxygen *** separate oxygen completely,high-quality TiS2 samples were then synthesized from TiN and TiC using S2 gas,and the clean sulfides were finally reduced toα-Ti powders with spherical morphology using electrolysis in molten CaCl_(2).Xray diffraction(XRD),scanning electron microscopy(SEM)in conjunction with energy-dispersive X-ray spectroscopy(EDS),and elemental LECO analysis were used to study the phases and microstructures of the sulfides and the electrochemically reduced *** Ti powder showed no carbon contamination and consisted of high-purity foil-like Ti sheets with very low oxygen,carbon,and nitrogen contents of less than 0.15 wt%O,0.02 wt%C,and 0.003 wt%N,*** quality of the Ti powder was much higher than that of the powder obtained using the conventional OS process(proposed by *** and ***)starting directly from the oxides.

Effects of mineralocorticoid receptor antagonists on responses to hemorrhagic shock in rats

World Journal of Critical Care Medicine 2018年第1期7卷 1-8页

AIM To evaluate the effects of mineralocorticoid receptor(MR) antagonists on mortality and inflammatory responses after hemorrhagic shock(HS) in *** One hundred and two male Sprague–Dawley rats were randomly assigned to one of the following three groups: Control, spironolactone (SPL), and eplerenone(EP) groups. HS was induced by the removal of blood. One half of rats were evaluated to determine mortality, hemodynamics, plasma tumor necrosis factor-alpha(TNF-α) concentrations, and arterial blood gas at 8 h afterHS recovery. In the remainder of rats, the expression levels of genes encoding cytokines were evaluated in liver tissue samples at 1 h after HS recovery. RESULTS The survival rates 8 h after HS recovery were 71%, 94%, and 82% in the control, SPL, and EP groups, respectively. There were no significant differences in survival rates among the three groups (P = 0.219). Furthermore, there were no significant differences in gene expression levels in the liver or plasma TNF-α concentrations among the three groups(P = 0.888).CONCLUSION Pretreatment with MR antagonists did not improve mortality or cytokine responses in the liver after HS recovery in rats.
