Salomon Rondon 1 West Brom have announced the signing of Salomon Rondon for a club-record deal worth around £12million.The striker has joined the Baggies on a four-year deal from Zenit St Petersburg to become their fifth summer signing. The fee eclipses the £10million Albion, who host Manchester City in their opening Barclays Premier League game on Monday night, paid for Brown Ideye last summer.“I am very happy to be here,” Rondon told the club’s official site.“This is a new opportunity in my career. I can’t wait to be with the other players and to play.“The club showed a lot of interest in me. That’s what is important for a player, what you take into account – and there are expectations of me.” Venezuela international Rondon, who has also played for Malaga and Rubin Kazan, scored 20 goals in 37 games for Zenit last season to tempt Albion boss Tony Pulis to splash out.“He’s got a fantastic goalscoring record in some of the top leagues in Europe and for his country,” Pulis said. “He’s 25 years of age and still to fulfil his full potential.“We hope he hits the ground running, of course, but understand it might take him time to settle. I’m sure our fans will help him and get behind him.“But we feel with age on his side and the prices English clubs are asking for their players, it’s a deal worth doing.“He comes highly recommended. I have spoken to Manuel (Pellegrini) and AVB (Andre Villas-Boas), who have worked with him (at Malaga and Zenit, respectively), and they were full of praise for the lad. We are looking forward to working with him.”
Brittle stars are included within a whole range of species, which contribute to knowledge in the medically important area of tissue regeneration. All brittle stars regenerate lose limbs, but the rate at which this occurs is highly variable and species-specific. One of the slowest rates of arm regeneration reported so far is that of the Antarctic Ophionotus victoriae. Additionally, O. victoriae also has an unusual delay in the onset of regeneration of about 5 months. Both processes are of interest for the areas of regeneration biology and adaptation to cold environments. One method of understanding the details of regeneration events in brittle stars is to characterise the genes involved. In the largest transcriptome study of any ophiuroid to date, we describe the results of mRNA pyrosequencing from pooled samples of regenerating arms of O. victoriae. The sequencing reads resulted in 18,000 assembled contiguous sequences of which 19% were putatively annotated by blast sequence similarity searching. We focus on the identification of major gene families and pathways with potential relevance to the regenerative processes including the Wnt/β-catenin pathway, Hox genes, the SOX gene family and the TGF beta signalling pathways. These data significantly increase the amount of ophiuroid sequences publicly available and provide candidate transcripts for the further investigation of the unusual regenerative process in this Antarctic ophiuroid.
