are needed to aid diagnosis of ichthyobodosis and epizootiological studies on Ichthyobodo spp. We have designed a specific quantitative real-time Selonsertib nmr PCR assay targeting SSU rDNA for the detection of Ichthyobodo spp. infections. Also, several novel primer sets are presented for use in identification of Ichthyobodo spp. through PCR and sequencing. These PCR methods have been optimized and tested on samples from wild caught and farmed fish from different
geographical areas in Norway. The real-time PCR assay has been tested for sensitivity and efficiency, and we present data demonstrating its use for absolute quantification of Ichthyobodo salmonis in tissue samples through RT-qPCR and qPCR. We demonstrate the use of the
described set of molecular tools for the detection and sequencing of Ichthyobodo spp. from farmed and wild fish, and also show that they may aid the discovery of new Ichthyobodo species. The detection of light Ichthyobodo spp. infections through microscopy is time consuming and less sensitive compared to PCR methods. Initial real-time PCR testing and subsequent sequencing of positive samples is a powerful method that will increase diagnostic precision, aid carrier detection and promote species discoveries in the Ichthyobodonidae. Our preliminary observations indicate a high Ichthyobodo spp. diversity. (C) 2012 Elsevier Ireland Ltd. All rights reserved.”
“Background and Objective: Some studies have PD0325901 shown that laser phototherapy is able to increase skin flap viability by decreasing the necrotic area and increasing neoangiogenesis. However, the mechanism by which laser acts on cells is not fully understood. The present study investigated the effects of two different laser wavelengths at 30 and 40 J/cm(2) on the viability of skin flap in rats. Material and Methods: Sixty male animals were used in this study. They were distributed into the following groups (n = 12 each group): control group, group irradiated with 660nm at 30 J/cm(2); group irradiated with 780 nm, at 30 J/cm(2), group irradiated with
660nm at 40 J/cm(2); and group irradiated with 780nm at 40 J/cm(2). The skin flap was performed on the back Combretastatin A4 order of all animals studied, with a plastic sheet interposed between the flap and the donor site. Laser irradiation was done immediately after the surgery and on days 1, 2, 3, and 4 post-surgery. The percentage of the necrotic area of the flap was calculated at day 7 post-surgery. Results: Control group showed a necrotic area of 62.83%. Interestingly, no statistically significant differences were found among the treated groups and the control group. Conclusion: This present study showed that 660nm and 780nm lasers at doses of 30 and 40 J/cm(2) were not effective for decreasing the necrotic area of the skin flaps in rats.
