Gaseous elemental mercury [Hg(0)] emissions from soils constitute a large fraction of global total Hg(0) emissions. Existing studies do not distinguish biotic- and abiotic-mediated emissions and focus only on photoreduction mediated emissions, resulting in an underestimation of soil Hg(0) emissions into the atmosphere. In this study, directional mercury (Hg) reduction pathways in paddy soils were identified using Hg isotopes.

An understanding of mercury (Hg) transformation processes in paddy soils is urgently needed in order to control Hg contamination of human food and related health impacts. Sulfur (S)-regulated Hg transformation is one important process that controls Hg cycling in agricultural fields.

Neutrophil extracellular traps (NETs) are characterized by a extracellular fibrous network structure produced by neutrophils with DNA and proteins. NETs can be formed by NADPH-dependent NETosis and NADPH-independent NETosis. After formation, it is not only hydrolyzed by DNase in plasma but can also be degraded intracellularly and extracellularly by macrophages and dendritic cells.

However, a comparison of the efficacy of porcine ALG (pALG) and rabbit ATG (rATG) as a first-line treatment for acquired SAA has not been reported. In the present study, we retrospectively analyzed SAA patients treated with either pALG (n = 43) or rATG (n = 32) and compared their hematologic responses and survivals.

Objective: To explore the immuno-effect of plasmacytoid dendritic cells (pDC) on bacteria infection induced spontaneous remission (SR) of leukemia.
Methods: Both pDC and myeloid dendritic cells (mDC) were isolated and purified from leukemic patient with SR and healthy donor by combination of immunomagnetic beads and flow cytometry. pDC were cultured in RPMI1640 medium and stimulated with different bacteria.

Spontaneous remission (SR) of leukemia is a rare event in clinic, which possibly correlated with severe infection and sepsis, but its exact mechanism has not been confirmed. Plasmacytoid dendritic cells (pDC) and myeloid dendritic cells (mDC) play a key role in innate and adaptive immunity respectively. A patient with severe infection of staphylococcus aureus acquired completely spontaneous remission (SR), moreover a increased number of pDC were observed, suggesting that bacteria-activated pDC may play an important role in SR.
