The sensitising effect of ORI on FLC in the treatment of C. albicans also included the promotion of apoptosis.

We demonstrated that combining azoles with ORI exerted potent synergism and that ORI could promote sensitisation to azoles in azole-resistantC. albicans. The discovery that ORI can effectively inhibit drug efflux and promote apoptosis may provide new insights and therapeutic strategies to overcome increasing azole resistance in C. albicans.

To evaluate the bleaching efficacy of a violet radiation (VR) combined or not with bleaching gels on the color and mineral content of stained teeth.

Enamel/dentin blocks were obtained and stained (n = 50) with coffee, red wine, tobacco smoke, or were left non-stained. The stained or not-stained blocks (n = 10) were distributed into five bleaching groups (n = 10) VR, CP (37 % carbamide peroxide), VR/CP, HP (35 % hydrogen peroxide), and VR/HP. Color (ΔE
ΔL, Δa, and Δb) and whiteness index (ΔWI
) changes were evaluated after staining and after bleaching using a spectrophotometer. Calcium (Ca), phosphorous (P), and Ca/P contents (in wt%) were measured after bleaching using energy-dispersive X-ray spectroscopy (EDS). Data was statistically analyzed (α = 0.05) using two-way ANOVA and Tukey tests (ΔE
ΔWI
, ΔL, Δb, wt%) or Kruskal-Wallis and Dunn tests (Δa).

VR alone caused higher colorimetric changes on coffee, tobacco and red wine-stained groups compared to non-stained enamel (p < 0.05). VR/CP exhibited higher colorimetric changes compared to CP in coffee and non-stained groups. The VR/CP, HP and VR/HP groups exhibited no change differences (p > 0.05). No differences were observed for the wt% of Ca, P and Ca/P between the groups.

The violet radiation was more effective in bleaching stained rather than non-stained teeth. VR combined with 37 % carbamide peroxide was as effective as the HP agent. Besides, no adverse effects could be observed in the enamel mineral content, regardless of the bleaching protocol tested, according to the EDS semi-quantitative analysis.

They are considered to be functional ancestors of antibodies and are classified into short and long types. In this study, we show that a pentraxin-like component (Ptx-like) with a C-terminal PTX domain, highly homologous to the short PTX of H. sapiens CRP, and a long N-terminal domain typical of long PTXs, is involved in the inflammatory response of Ciona robusta under LPS exposure in vivo. Analyses of protein domains as well as 3D modelling and phylogenetic tree supported the close relationship of Ptx-like with mammalian CRP, suggesting that C. robusta Ptx-like shares a common ancestor in the chordate lineages. qRT-PCR analysis showed that Ptx-like was transcriptionally upregulated during the inflammatory process induced by LPS inoculation and that it is involved in the initial phase as well as the secondary phase of the inflammatory response in which matrix remodelling and the achievement of homeostasis occur. In situ hybridisation assays revealed that gene transcription was upregulated in the pharynx post-LPS challenge in vivo, and that Ptx-like was expressed by clusters of haemocytes, mainly granulocytes, inside the pharynx vessels. We also found transcript-expressing granulocytes flowing in the musculature and in the lacunae of the circulatory system. These data supported that Ptx-like is a potential molecule of the acute-phase response in C. robusta immune defence systems against bacterial infection.CD154, a member of the TNF superfamily, is a multifunctional molecule highly expressed in activated T cells, and plays important roles in T cell-dependent humoral immune response. In this study, CD154 of Nile tilapia (Oreochromis niloticus) was identified, and its functions in the T cell-dependent immune response were demonstrated. The open reading frame (ORF) of OnCD154 is 699 bp, encoding a protein of 232 amino acids with a 23 amino acid transmembrane region. Amino acid sequence of OnCD154 is highly homologous to that of other teleost fish, especially rainbow trout. Quantitative real-time PCR (qRT-PCR) demonstrated that mRNA of OnCD154 is highly expressed in immune organs, especially in spleen, thymus, gills, head kidney, etc. In addition, the anti-OnCD154 polyclonal antibody (anti-(r)OnCD154) was successfully prepared, and it can react with natural protein in head kidney leukocytes. Following two immunizations with keyhole limpet hemocyanin (KLH) in vivo, the significantly up-regulated expression level of OnCD154 mRNA appeared earlier (fifth day) and higher (42.9 folds) in the second challenge than the first on in head kidney. Further, after stimulation with KLH in vitro, the expressions of T cell-dependent immune response-related molecules (activated T cell specific surface molecules CD3ε and CD154) and B cell differentiation-related molecules (Blimp1 and sIgM) and CD40 were significantly up-regulated in head kidney leukocytes. Moreover, the up-regulated expressions of these molecules were blocked with the treatment of anti-(r)OnCD154 antibody. Taken together, these results indicate that OnCD154 might get involved in T cell-dependent immune response, and provide a new insight into the humoral immune response of teleost fish.Tumor necrosis factor receptor 1 (TNFR1) associated death domain protein (TRADD) is a pivotal adaptor in TNF signaling pathway and up-regulates MAVS/IFN signaling pathway in human and mammal. However, the role of TRADD in teleost fish remains obscure. To reveal the function of teleost TRADD in the innate immune response, the TRADD homologue (bcTRADD) of black carp (Mylopharyngodon piceus) has been cloned and the function of bcTRADD is investigated in this study, which shares similar functional domain to its mammalian counterpart. bcTRADD mRNA expression level increased in response to different stimuli, including LPS, poly (IC) and virus infection in host cells. bcTRADD activated the transcriptional activity of NF-κB promoter in the reporter assay; however, showed hardly any effect on the transcriptional activity of IFN promoter. It was interesting that black carp mitochondria antiviral signaling protein (bcMAVS)-activated IFN promoter transcription were dramatically depressed by bcTRADD and the C-terminal death domain of bcTRADD was indispensable for its regulation of bcMAVS.
