Wolbachia‐infected Trichogramma dendrolimi is outcompeted by its uninfected counterpart in superparasitism but does not have developmental delay

Jin‐Cheng Zhou, Dan Shang, Shi‐Meng Liu, Chen Zhang, more

Pest Management Science > 79 > 3 > 1005 - 1017

BACKGROUND Wolbachia infection increases the superparasitism frequency of Trichogramma females and provides an opportunity for horizontal intraspecific transmission. However, superparasitism may lead to interstrain competition between Wolbachia‐infected Trichogramma offspring and their uninfected counterparts. This study investigated the outcome of interstrain intrinsic competition between Wolbachia...

Cheng‐Peng Sun, Dong Sun, Zhi‐Lin Luan, Xin Dai, more

Journal of Clinical Laboratory Analysis > 34 > 8 > n/a - n/a

Background Diverse and circumstantial evidence suggests that schizophrenia is a neurodevelopmental disorder. Genes contributing to neurodevelopment may be potential candidates for schizophrenia. The human SOX11 gene is a member of the developmentally essential SOX (Sry‐related HMG box) transcription factor gene family and mapped to chromosome 2p, a potential candidate region for schizophrenia. ...

Study of ZnSe powder mass depleted in temperature field

Minqiang Wang, Xiao Huo, Jianping Li, Zhonghai Lin, more

Ceramics International > 2008 > 34 > 4 > 1081-1083

Evaporative crystallization of nano-particles involves a complicated multiphase mass and heat transfer process that is dependent on the crystal size in a temperature field. It becomes more complicated for the crystallization of ZnSe powders using this method because of multiprocesses including sublimation, crystallization, and decomposition. This work reports our preliminary studies on the evaporation...
