The relationship between culling rate, herd structure and production efficiency in a pig nucleus herd
pig computer simulation culling rate
font style='font-size:12px;'>
2015/6/8
Computer simulation of sow culling was run in a nucleus herd. The specified constant culling rate from 15 to 21% was simulated for all parities. The resultant different age structure of a herd was stu...
An 'environment to nucleus' signaling system operates in B lymphocytes: redox status modulates BSAP/Pax-5 activation through Ref-1 nuclear translocation

2014/12/12
The Ref-1 (also called APE or HAP1) protein is a bifunctional enzyme impacting on a wide variety of important cellular functions. It acts as a major member of the DNA base excision repair pathway. Mor...
Notch functions from the cytoplasm to the nucleus during T cell activation
Cytokines T cells activate cells cell signal
font style='font-size:12px;'>
2014/12/11
Notch1 specifically upregulates expression of the cytokine interferon-γ in peripheral T cells through activation of NF-κB. However, how Notch mediates NF-κB activation remains unclear. NF-κB activatio...
TRAF-interacting protein, an inhibitor of the canonical nuclear factor-kappaB pathway, plays a key role in the estradiol -dependent apoptosis of the dual-phenotype gamma amino butyric acid/glutamate neurons in the anteroventral periventricular nucleus of the male rat
