The influence of GO powders’ type and content on crystallization

The influence of GO powders’ type and content on crystallization behavior of PTT was investigated by differential scanning calorimeter (DSC) and polarized optical microscopy (POM). DSC results indicated that the overall crystallization rate of PTT was accelerated by well-dispersed GO material which acts as a heterogeneous nucleation agent, since the

Avrami parameter obtained is near 3. On the contrary, large GO aggregates which is in the minority will hinder the nucleation. Interestingly, large and well-defined PTT Adavosertib ic50 spherulites instead of tremendous stunted spherulites were observed from POM, which means only a small portion of GO powders was acted as nucleation agent. Meanwhile, GO powders had no effect on PTT spherulites growth rate. In addition, the band spacing of PTT spherulites became weaker and wider with increasing GO content.

“Wingless-type MMTV integration site family, member 10B (WNT10B)

may play an important role in inhibiting differentiation of preadipocytes in vitro and impairing adipose development in vivo. In this study, based on DNA sequencing and PCR-RFLP methods, we attempted to characterize the associations between common genetic polymorphisms in WNT10B and growth traits of 435 female cattle from three breeds (Jiaxian. Qinchuan and Luxi cattle). The results indicated that g.220A>G was in the intron 1, and g.1617C>T, g.3980G>T, g.4711G>C were in the coding selleck kinase inhibitor region. At the g.3980G>T locus, Jiaxian cattle individuals with genotype

TT had greater body length than those with genotypes GG and GT (P < 0.05). At the g.220A>G locus, Qinchuan cattle individuals with genotype GG had greater growth traits than those with genotype AA and AG (P < 0.05 or P<0.01). These statistical results showed that the WNT10B gene might be a potential candidate gene for marker-assisted selection (MAS). (C) 2012 Published Navitoclax by Elsevier Ltd.”
“Background: Objective was to determine whether fear for external cephalic version (ECV) and depression are associated with the success rate of ECV in women with a breech presentation at term.\n\nMethods: Prospective study conducted in the Catharina Hospital Eindhoven between October 2007 and May 2012. Participants fulfilled The Edinburgh Depression Scale (EDS) questionnaire and expressed their degree of fear on a visual analogue scale from one to ten before ECV. Obstetric factors were evaluated as well. Primary outcome was the relation between psychological factors (fear for ECV and depression EDS scores) and ECV success rate. Secondary outcome was a possible relation between fear for ECV and increased abdominal muscle tension.\n\nResults: The overall success rate was 55% and was significantly lower (p < 0.
