Five solid media were evaluated for isolation of Aeromonas spp. from faeces: desoxycholate citrate agar (DCA), MacConkey's agar (MAC), xylose-desoxycholate-citrate agar (XDCA), Rogol's medium (ROG), which contained ampicillin 20 mg/L and p-nitrophenyl-glycerine 25 mg/L as inhibitors, and blood agar (BA)...

Nontypeable Haemophilus influenzae (NTHi) is a Gram-negative, opportunistic pathogen that frequently causes ear infections, bronchitis, pneumonia, and exacerbations in patients with underlying inflammatory diseases, such as chronic obstructive pulmonary disease. In mice, NTHi is rapidly cleared, but a strong inflammatory...

PRDM (PRDI-BF1 and RIZ homology domain containing) family members are sequence-specific transcriptional regulators involved in cell identity and fate determination, often dysregulated in cancer. The PRDM15 gene is of particular interest, given its low expression in adult tissues and its...

Calcineurin is required for B cell receptor (BCR)-induced proliferation of mature B cells. Paradoxically, loss of NFAT transcription factors, themselves calcineurin targets, induces hyperactivity, which suggests that calcineurin targets other than NFAT are required for BCR-induced proliferation. Here we demonstrate...
