Conditional gene expression and gene deletion are important experimental approaches for examining the functions of particular gene products in development and disease. The cre-loxP system from bacteriophage P1 has been used in transgenic animals to induce site-specific DNA recombination leading to gene activation or deletion. To regulate the recombination in a spatiotemporally controlled manner, we constructed a recombinant adenoviral vector, Adv/cre, that contained the cre recombinase gene under regulation of the herpes simplex virus thymidine kinase promoter. The efficacy and target specificity of this vector in mediating loxP-dependent recombination were analyzed in mice that had been genetically engineered to contain loxP sites in their genome. After intravenous injection of the Adv/cre vector into adult animals, the liver and spleen showed the highest infectivity of the adenovirus as well as the highest levels of recombination, whereas other tissues such as kidney, lung, and heart had lower levels of infection and recombination. Only trace levels of recombination were detected in the brain. However, when the Adv/cre vector was injected directly into specific regions of the adult brain, including the cerebral cortex, hippocampus, and cerebellum, recombination was detectable at the injection site. Furthermore, when the Adv/cre vector was injected into the forebrains of neonatal mice, the rearranged toxP locus from recombination could be detected in the injected regions for at least 8 weeks. Taken together, these results demonstrate that the Adv/cre vector expressing a functional cre protein is capable of mediating loxP-dependent recombination in various tissues and the recombined gene locus may in some cases be maintained for an extended period. The use of the adenovirus vector expressing cre combined with localized delivery to specific tissues may provide an efficient means to achieve conditional gene expression or knockout with precise spatiotemporal control.

New low cost sensors and open free libraries for 3D image processing are making important advances in robot vision applications possible, such as three-dimensional object recognition, semantic mapping, navigation and localization of robots, human detection and/or gesture recognition for human-machine interaction. In this paper, a novel method for recognizing and tracking the fingers of a human hand is presented. This method is based on point clouds from range images captured by a RGBD sensor. It works in real time and it does not require visual marks, camera calibration or previous knowledge of the environment. Moreover, it works successfully even when multiple objects appear in the scene or when the ambient light is changed. Furthermore, this method was designed to develop a human interface to control domestic or industrial devices, remotely. In this paper, the method was tested by operating a robotic hand. Firstly, the human hand was recognized and the fingers were detected. Secondly, the movement of the fingers was analysed and mapped to be imitated by a robotic hand.
