The characteristics of excitatory lineage differentiation and the developmental conservation in Reeler neocortex.

The majority of neocortical projection neurons are generated indirectly from radial glial cells (RGCs) mediated by intermediate progenitor cells (IPCs) in mice. IPCs are thought to be a great breakthrough in the evolutionary expansion of the mammalian neocortex. However, the precise ratio of neuron production from IPCs and characteristics of RGC differentiation process are still unclear.

Paeoniflorin ameliorates depressive-like behavior in prenatally stressed offspring by restoring the HPA axis- and glucocorticoid receptor- associated dysfunction.

Background: Prenatal stress (PS) can increase the risk of nervous, endocrine and metabolic diseases and induce depression in offspring. Paeoniflorin (PA) is an amorphous glucoside isolated from the aqueous extract of roots of the peony plant (Paeonia lactiflora Pall.) and exerts various pharmacological effects in the nervous system.

Icariin ameliorates learning and memory impairments through ERK/CaMKIIα/CREB signaling and HPA axis in prenatally stressed female offspring.

Background: Prenatal stress (PS) leads to a wide variety of behavioral and emotional aberration observed in later life, particularly in the impairment of spatial learning and memory in offspring. Icariin (ICA) is a naturally occurring furanocoumarin and exhibits many pharmacological properties, including potent improvement on learning and memory.

Purpose: We pretend to investigate the improvement of ICA on learning and memory impairment in PS.

[Residence time distributions and spatial variation of N, P in the subsurface-flow constructed wetlands for purification of eutrophic aquaculture water].

Hydraulic residence time distributions (RTD) and spatial variations of N, P were studied in a small-scale horizontal subsurface-flow constructed wetlands (HSFCWs) planted with Cyperous alternifolius and Typha angustifolia respectively for purification of eutrophic aquaculture water. The results show that the residence time distribution curves of the investigated HSFCWs lie between plug-flow and completely mixed model with characteristic values (sigma2) of 0.3246 and 0.

[Electrofusion of building coupling system for degrading anthracene and fusants' choices].

Some researches have been carried out for the electro fusion of building coupling system for degrading anthracene and the choices of fusants. During the experiments, total rate of fusion stable in alternation current frequency 500 kHz, impulse intensity 300 V/cm, impulse width 5 micros, amount of impulse 2 and alternation current intensity 20-40 V/cm were found. The resistant plate with erythromycin and ampicillin can screen the fusant of autochthonous bacterium and surfactant-producing bacterium.
