[Effects of acute fear stress on spatial memory and neuronal plasticity in the medial prefrontal cortex in mice].

The purpose of this study was to investigate the effects of acute fear stress on the spatial memory and neuronal plasticity of medial prefrontal cortex (mPFC) neurons in mice, and to elucidate the mechanisms underlying mPFC plasticity and post-stress memory regulation. Male C57BL/6 mice (6 weeks old) were randomly divided into control group and stress group. Foot shock stress was applied to establish an acute fear stress model.

Effect of Homebuyer Comment on Green Housing Purchase Intention-Mediation Role of Psychological Distance.

Green housing is a new type of building that advocates energy saving and environmental protection. How to stimulate buyers to buy green housing under the background of high cost is the key problem to guide green consumption. First of all, based on the existing literature, the comment of homebuyers was divided into comment quantity, comment quality, comment titer and evaluator credibility.

[Bioinformatics analysis and significance of expression of CC chemokine ligand 23 (CCL23) in hepatocellular carcinoma].

Objective To investigate the expression of C-C motif chemokine ligand 23 (CCL23) in hepatocellular carcinoma (HCC) and its clinical significance for survival and prognosis. Methods GEPIA, HCCDB, MetaScape, TIMER, TISIDB, Kaplan-Meier Plotter and other online databases were used to analyze the expression level of CCL23 in HCC, the functional notes of co-expression gene and its gene ontology (GO), the enrichment of Kyoto gene and genome encyclopedia (KEGG), the correlation between tumor cell purity, the expression of CCL23 in immune cells and its significance for survival and prognosis of patients. Results The expression of CCL23 in all stages of HCC was negatively correlated with the purity of HCC tumor cells.

Physiological responses of somaclonal variants of triploid bermudagrass (Cynodon transvaalensis x Cynodon dactylon) to drought stress.

Eight somaclonal variants with enhanced drought tolerance were isolated from regenerated plants of triploid bermudagrass (Cynodon dactylon x Cynodon transvaalensis cv., TifEagle). Three of them (10-17, 89-02, 117-08) with strong drought tolerance were selected for investigations of physiological responses to drought stress.
