Precipitation behaviour of wrought Al-6Mg alloys with ternary scandium and quaternary zirconium and titanium has been studied. Hardness measurements and resistivity studies are employed to assess the precipitation behaviour of scandium doped Al-6Mg alloy without or with quaternary additions of zirconium and titanium. Further, the kinetics of precipitations are studied by differential scanning c...

The incorporation of tendon graft into bone tunnel is one of the most challenging clinical issues in anterior cruciate ligament (ACL) reconstruction. As a biodegradable metal, Mg has appropriate mechanical strength and osteoinductive effects, thus may be a promising alternative to commercialized products used for graft fixation. Therefore, it was hypothesized that Mg based interference screws w...

OBJECTIVE To reassess endometrial morphological criteria of normality identifying the best morphological and molecular "implantation window" indicators in normal women. DESIGN Prospective clinical study. SETTING Assisted reproductive unit. PATIENT(S) Fourteen healthy volunteers. INTERVENTION(S) Blood sampling for LH, E(2), and progesterone (P4) determinations. Daily vaginal ultrasounds....

background: leukemia inhibitory factor (lif) is a neurortophic cytokine which plays an important role in the neural cell survival. expression of lif and its receptor, lifr, in different brain regions has been demonstrated. based on evidences lif plays an important role in the modulation of neurogenesis and glial responses to injury. up-regulation of lif after central nervous system (cns) damage...

The innovative titanium-magnesium composite (Ti-Mg) was produced by powder metallurgy (P/M) method and is characterized in terms of corrosion behavior. Material and methods: Two groups of experimental material, 1 mass% (Ti-1Mg) and 2 mass% (Ti-2Mg) of magnesium in titanium matrix, were tested and compared to commercially pure titanium (CP Ti). Immersion test and chemical analysis of four soluti...

We report optical damage resistant nearstoichiometric Ti:Mg:Er:LiNbO3 single-mode strip waveguides fabricated on congruent LiNbO3 by Er diffusion, Mg/Ti codiffusion, and vapor-transport-equilibration process. The waveguide optical properties, compositions, crystalline phases and Mg, Er and Ti profiles were characterized, and stable signal enhancement has been measured with >200mW pump power. Ke...
