This study aimed to evaluate the effects of Bifidobacterium breve CCFM683 on psoriasis and to investigate the underlying mechanisms. Bifidobacterium breve CCFM683 significantly ameliorated psoriasis in mice as well as elevated the deoxycholic acid (DCA) and lithocholic acid (LCA) in the colon compared with those of the imiquimod-treated mice. Meanwhile， B. breve CCFM683 increased the relative abundance of DCA-producing Lachnoclostridium and diminished the harmful Desulfovibrio and Prevotellaceae UCG001. Additionally， the farnesoid X receptor (FXR) in the skin was activated and the expression of the TLR4/NF-κB pathway was inhibited， and the downstream IL-17 and TNF-α were downregulated whereas IL-10 was up-regulated . Moreover， the subsequent hyperproliferation of keratinocytes and the dysfunction of the epidermal barrier were improved. In conclusion， CCFM683 administration ameliorated IMQ-induced psoriasis via modulating gut microbiota， promoting the DCA production， regulating the FXR-TLR4/NF-κB pathway， diminishing proinflammatory cytokines， and regulating keratinocytes and epidermal barrier. These findings may be conducive to elucidating the mechanism for probiotics to ameliorate psoriasis and to promote its clinical trials in skin disease.

Male cognition has gained recognition as an important potential player in sexual selection. A number of studies have found positive correlations between male sexual signals and cognitive performance an d/or female pref ere nces for males with better cog nitive performance, although other studies have not fou nd these relati on ships. Sex roles can differ dramatically, and sex differen ces in selection on cog nition likely follow from the different tasks associated with these sex roles. Here, using threespine stickleback Gasterosteus aculeatus, a species with clearly diverge nt sex roles and mutual mate choice, we focus on the cognitive trait inhibitory control because males must differentially respond to reproductive females versus other sticklebacks while defending territories and refrain from eating eggs and fry while performing paternal care. We presented fish with a detour task four times over a period of 7 days, allowing us to assess initial inhibitory control and improvement over time. We ask 1) whether there are sex differences in inhibitory control and 2) whether male mate choice is associated with female inhibitory control. Although males outperformed females on three different measures of detour task performance across four trials, these differences were largely explained by males being less neophobic than females. Females took more trials to successfully solve the detour task, even after accounting for sex differences in neophobia. Female cognitive abilities, however, were unrelated to the vigor with which males courted them. The equivocal results regarding sex differences in cognitive ability suggest further study given the very different selection pressures each sex experiences.

Air entrapment is an important consideration in environments with shallow water tables and sandy soil, like the condition of highly conductive sandy soils and flat topography in Florida, USA. It causes water table rises in soils, which are significantly faster and higher than those in soils without air entrapment. Two numerical models, Integrated Hydrologic Model (IHM) and HYDRUS-1D (a single-phase, one-dimensional Richards′ equation model) were tested at an area of west central Florida to help further understanding the shallow water table behavior during a long term air entrapment. This investigation employed field data with two modeling approaches to quantify the variation of air pressurization values. It was found that the air pressurization effect was responsible at time up to 40 cm of water table rise being recorded by the observation well for these two models. The values of air pressurization calculated from IHM and HYDRUS-1D match the previously published values. Results also indicated that the two numerical models did not consider air entrapment effect (as the predictive parameters remain uncertain) and thus results of depth to water table from these models did not compare to the observations for these selected periods. Incorporating air entrapment in prediction models is critical to reproduce shallow water table observations.

长期以来2.7~2.8 Ga被普遍接受为华北克拉通太古宙地壳生长的主峰期,与全球地壳生长同步,其主要依据是华北克拉通多数锆石的亏损地幔Hf模式年龄的峰值分布在2.7~2.8 Ga.然而Hf模式年龄受源区成分和地幔模式的选择以及源区不均一性等多种因素影响,具体数值未必有确切地质含义.而全球公认的2.7 Ga地壳生长峰期并非依据模式年龄,而主要依据:以绿岩带为代表的巨量镁铁质岩浆活动峰期在2.7 Ga,由此引发的巨量长英质岩浆活动峰期在2.7 Ga,全球地幔亏损事件的峰期也在2.7 Ga.与此相对应,对于华北克拉通,以绿岩带为代表的巨量镁铁质岩浆活动峰期在2.5 Ga,由此引发的巨量长英质岩浆活动峰期也在2.5 Ga.因此,如不考虑不同构造背景保存偏差的影响,~2.5 Ga应被视作华北克拉通较为明确的地壳生长的主峰期.

Background： There is considerable interest in using goats as models for genetically engineering dairy animals and also for using stem cells as therapeutics for bone and cartilage repair. Mesenchymal stem cells （MSCs） have been isolated and characterized from various species, but are poorly characterized in goats. Results： Goat MSCs isolated from bone marrow （BM-MSCs） and adipose tissue （ASCs） have the ability to undergo osteogenic, adipogenic and chondrogenic differentiation. Cytochemical staining and gene expression analysis show that ASCs have a greater capacity for adipogenic differentiation compared to BM-MSCs and fibroblasts. Different methods of inducing adipogenesis also affect the extent and profile of adipogenic differentiation in MSCs. Goat fibroblasts were not capable of osteogenesis, hence distinguishing them from the MSCs. Goat MSCs and fibroblasts express CD90, CD105, CD73 but not CD45, and exhibit cytoplasmic localization of OCT4 protein. Goat MSCs can be stably transfected by Nucleofection, but, as evidenced by colony-forming efficiency （CFE）, yield significantly different levels of progenitor cells that are robust enough to proliferate into colonies of integrants following G418 selection. BM-MSCs expanded over increasing passages in vitro maintained karyotypic stability up to 20 passages in culture, exhibited an increase in adipogenic differentiation and CFE, but showed altered morphology and amenability to genetic modification by selection. Conclusions： Our findings provide characterization information on goat MSCs, and show that there can be significant differences between MSCs isolated from different tissues and from within the same tissue. Fibroblasts do not exhibit trilineage differentiation potential at the same capacity as MSCs, making it a more reliable method for distinguishing MSCs from fibroblasts, compared to cell surface marker expression.
