Acceptability and usability of 'One Key Question'® in Australian primary health care.

Background: Around one-third of pregnancies in women attending antenatal care are unintended. This means a substantial number of women enter pregnancy without optimising their health prior to conception. Primary care practitioners are uniquely placed to counsel women about how to plan for pregnancy and about how to avoid unintended conception.

Roquin-2 shares functions with its paralog Roquin-1 in the repression of mRNAs controlling T follicular helper cells and systemic inflammation.

Accumulation of T follicular helper (Tfh) cells and proinflammatory cytokines drive autoantibody-mediated diseases. The RNA-binding protein Roquin-1 (Rc3h1) represses the inducible costimulator ICOS and interferon-γ (IFN-γ) in T cells to prevent Tfh cell accumulation. Unlike Rc3h1(san) mice with a mutation in the ROQ domain of Roquin-1, mice lacking the protein, paradoxically do not display increased Tfh cells.

Identification of Bcl-6-dependent follicular helper NKT cells that provide cognate help for B cell responses.

Lipid antigens trigger help from natural killer T cells (NKT cells) for B cells, and direct conjugation of lipid agonists to antigen profoundly augments antibody responses. Here we show that in vivo, NKT cells engaged in stable and prolonged cognate interactions with B cells and induced the formation of early germinal centers. Mouse and human NKT cells formed CXCR5(+)PD-1(hi) follicular helper NKT cells (NKT(FH) cells), and this process required expression of the transcriptional repressor Bcl-6, signaling via the coreceptor CD28 and interaction with B cells.

Estradiol valerate and intake of sweetened water.

Recently, it has been shown that female rats receiving very large doses (e.g., 2 mg) of estradiol valerate (EV) take considerably more alcoholic beverage than placebo controls.
