Paddy fields are a major emission source of the greenhouse gas methane. In the present study, the addition of ferrihydrite to xylan-amended paddy soil microcosms suppressed methane emissions. PCR-based and metatranscriptomic ana-lyses revealed that the addition of ferrihydrite suppressed methanogenesis by heterogeneous methanogens and simultaneously activated Geobacteraceae, the most abundant iron-reducing diazotrophs.

Objectives: The aims of this study were (1) to develop a decision-making aid for couples hesitant about transitioning from infertility treatment to advanced assisted reproductive technology, (2) to examine the adequacy of this aid, and (3) to evaluate its usability. After the first version of the decision-making aid was created, the first version was supervised and finally a prototype of the decision-making aid was completed. We conducted a feasibility study from February to March 2022.

Article Synopsis
  • Aging leads to an increase in senescence-associated (SA) CD4 T cells that don't respond to normal stimulation and promote spontaneous germinal center (Spt-GC) development, contributing to autoantibody production.
  • CD153 and its receptor CD30 are found on SA-T cells and Spt-GC B cells, and the absence of either protein hinders the growth of these cells.
  • Engaging CD153 helps restore TCR signaling in SA-T cells, while engaging CD30 promotes B cell expansion; blocking their interaction can reduce the rise of these cells and improve autoimmune conditions like lupus in mice.
