The paper titled " Therapeutic Management of the Hallux Rigidus " [1], published in Rehabilitation Research and Practice , has been retracted as it was found to contain substantial flaws in its scientific methodology.

The famous Black-Sholes (BS) and Cox-Ross-Rubinstein (CRR) formulas are basic results in the modern theory of option pricing in financial mathematics. They are usually deduced by means of stochastic analysis; various generalisations of these formulas were proposed using more sophisticated stochastic models for common stocks pricing evolution. In this paper we develop systematically a determinis...

CBP is a transcriptional coactivator required by many transcription factors for transactivation. Rubinstein-Taybi syndrome, which is an autosomal dominant syndrome characterized by abnormal pattern formation, has been shown to be associated with mutations in the Cbp gene. Furthermore, Drosophila CBP is required in hedgehog signaling for the expression of decapentapleigic, the Drosophila homolog...

In 1963 Rubinstein and Taybi described a new syndrome characterized by broad thumbs and toes, facial abnormalities and mental retardation. The syndrome can be observed in the neonatal period by typical thumbs, halluces and facial abnormalities. The prevalence in the general population is unknown, however the disorder is not rare and is present in about 1:600 patients in mental retardation clini...
