STK15 gene amplification and associated increased expression of the mitotic kinase it encodes are associated with aneuploidy and aggressive clinical behavior in human bladder cancer.
Abstract. Many researches in face recognition have been dealing with the challenge of the great variability in head pose, lighting intensity and direction,facial expression, and aging. The main purpose of this overview is to describe the recent 3D face recognition algorithms. The last few years more and more 2D face recognition algorithms are improved and tested on less than perfect images. However, 3D models hold more information of the face, like surface information, that can be used for face recognition or subject discrimination. Another major advantage is that 3D face recognition is pose invariant. A disadvantage of most presented 3D face recognition methods is that they still treat the human face as a rigid object. This means that the methods aren't capable of handling facial expressions. Although 2D face recognition still seems to outperform the 3D face recognition methods, it is expected that this will change in the near future.
Purpose: Split dose experiments were carried out with two 2 Gy fractions per day at intervals ranging from 0.5 to 24 h, in order to investigate both the time to complete repair and the detailed kinetics of repair of sublethal damage in the cervical spine of rats.Materials and methods: Male rats of the WAG/Rij strain were irradiated at 2 Gy/min with 18 MV photons to a length of 18 mm of cervical spinal cord. Four hundred twenty-three rats were irradiated without top-up doses to investigate whether repair was complete by 24 h or whether any slow repair or proliferation occurred up to 50 days after irradiation. Three hundred seventy-nine rats were also irradiated in split dose (2 Gy + At + 2 Gy each day) experiments, with intervals of 0.5, 1, 2 ,4 , 8 and 24 h. The split dose irradiations were followed by a single top-up dose of 15 Gy (producing about half the total damage).Results :
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
