AIM:To investigate the immune response of peripheral blood mononuclear cells(PBMCs)and dendritic cells (DCs)that were stimulated by probiotic preparations. METHODS:PBMCs were isolated,cultured,and stimulated with Bio-Three(a mixture of Bacillus mesentericus, Clostridium butyricum and Enterococcus faecalis;105, 10 6 and 10 7 CFU/mL for 24 h).Cytokine production of (1)circulating PBMCs;(2)PBMCs stimulated by probiotic preparation;(3)monocyte-derived DCs;and(4)DC andT cell co-culture was determined by enzyme-linked immunosorbent *** analysis of circulating PBMCs was also investigated by flow *** was obtained from individuals who consumed Bio-Three (10 9 CFU/d ***,*** and ***) for 2 wk,or those who did not take probiotics orally. RESULTS:In culture supernatants,interferon-γ(IFN-γ) and interleukin(IL)-10 production increased,but IL-4 and tumor necrosis factor-α(TNF-α)production by PBMCs decreased after 1 and 2 wk of probiotic *** cytometry was also performed on day 14 and detected enhanced expression of CD11b,HLA-DR, CD4,CD45RA,CD25,CD44 and CD69 in response to ***,IL-10 and IL-12 were upregulated in supernatants of monocyte-derived DCs,and IFN-γand IL-10 were enhanced in supernatants of CD4 + T cells co-cultured with DCs. CONCLUSION:Bio-Three appeared to stimulate the Th1 immune response,downregulate pro-inflammatory cytokines(TNF-α)and upregulate anti-inflammatory cytokine(IL-10).Probiotics could be effective in activation of PBMCs and DCs.

Impacts of external forcing and internal variability on the North Atlantic multidecadal variations since 1950

Science china Earth Sciences 2024年第8期67卷 2699-2701页

作者： Wenjian hua Aiguo DAI Key Laboratory of Meteorological Disaster Ministry of Education/Collaborative Innovation Center on Forecast and Evaluation of Meteorological DisastersNanjing University of Information Science and TechnologyNanjing 210044China Department of Atmospheric and Environmental Sciences University at AlbanyState University of New YorkAlbany 12222USA

The physical formation mechanisms of the Atlantic Multidecadal Variability(AMV)in the context of global warming have been a key research topic(Vecchi et al.,2017).The conventional view is that the AMV is mainly driven by internal dynamics within the climate system,especially in the Atlantic Ocean(Zhang et al.,2019).However,some studies suggest that decadal to multidecadal variations in North Atlantic sea surface temperature(SST)since around 1950 are related to anthropogenic and natural aerosol emissions(Otter?et al.,2010;Booth et al.,2012;hua et al.,2019).
