In Erhualian and Yorkshire reciprocal cross F1 pig populations, we examined the mRNA expression characteristic of liver-derived IGF-1, IGF-1R, IGF-2, IGF-2R and IGFBP-3 during the embryonic and postnatal developmental periods (E50, E70, E90, D1, D20, D70, D120 and D180). Our results demonstrated that the IGF-system genes mRNA levels exhibited an ontogenetic expression pattern, which was potenti...

The purpose of this study was to investigate how reciprocal teaching and self-regulation affected reading comprehension of EFL learners at the high school level. 60 participants were selected and randomly assigned into two groups: an experimental group and a control group. The experimental group was taught through reciprocal teaching while the control group was taught through skill-based teachi...

OBJECTIVE This project was directed at examination of the potential reciprocal relationship between empathy and social dominance orientation (SDO), with the purpose of testing the predictions from Duckitt's highly influential dual process model of prejudice, and further examining the validity of the mere effect view of social dominance orientation. METHOD To examine this relationship, the aut...

The frequencies of sex-linked lethal mutations arising in hybrid male offspring from crosses and in nonhybrid controls were determined. The hybrids were produced by crossing representative strains of the P-M system of hybrid dysgenesis in all possible combinations. Males from the cross of P males x M females had a mutation rate about 15 times higher than that of nonhybrid males from the P strai...

In this study, we selected natural polyploidy loach (diploid, triploid and tetraploid) and hybrid F₁ generation obverse cross (4 × 2) and inverse cross (2 × 4) by diploids and tetraploids as the research model. The MSAP (methylation-sensitive amplified polymorphism) reaction system was established by our laboratory to explore methylation levels and pattern diversification features at the whole ...

in the current study, two line with short-term divergent selection for high weight (hw) and low weight (lw) at 4 wk of age after 7 generation were analyzed in coturnix japonica quail. hw line was significantly higher than lw line at 28d of age (p<0.01). 21 females, and 11 male from the hw, 18 females plus 10 male from the lw lines were mated as reciprocal cross and within lines to produce hh, l...

We derive a result on the boundedness of the multiplicity of the singular values for Hankel operator, whose symbol is of the form F (z) := ∫ dλ(t ) z − t +R(z), where λ is a complex measure with infinitely many points in its support which is contained in the interval (−1,1), and whose argument has bounded variation there, while R is a rational function with all its poles inside of the unit disk...
