Retroviruses cause cancers in a variety of animals and humans. Research on retroviruses has provided important insights into mechanisms of oncogenesis in humans, including the discovery of viral oncogenes and cellular proto-oncogenes. The subject of this review is the mechanisms by which retroviruses that do not carry oncogenes (non-acute retroviruses) cause cancers. The common theme is that th...
The theory of behavioral communication for humanoid robots that in teract with humans is discussed in this paper For behavioral communication it is fundamental for a humanoid robot to recognize the meaning of the whole body mo tion of a human According to the previous works it can be done in the symbolic level by adopting the proto symbol space de ned by the Hidden Markov Models based on the mi...
Deep-sea hydrothermal vents are one of the most unique and fascinating ecosystems on Earth. Although phylogenetic diversity of vent communities has been extensively examined, their physiological diversity is poorly understood. In this study, a GeoChip-based, high-throughput metagenomics technology revealed dramatic differences in microbial metabolic functions in a newly grown protochimney (inne...
background & objective: the current approaches to reduce the risk of colorectal carcinoma are through the detection and removal of the precursor lesion” adenomatous polyps”. the study was conducted to evaluate the immunohistochemical expression of p53 and bcl2 in colorectal adenomas and carcinomas. patients and methods: a total of 86 cases, 33 colorectal adenomas, 33 colorectal adenocarcin...
The expression of c-sis proto-oncogene in bronchoalveolar mononuclear cells was studied in seven patients with pulmonary sarcoidosis. By means of nuclear run on transcription assay, the transcriptional level of c-sis proto-oncogene in bronchoalveolar mononuclear cells was investigated. Expression of c-sis proto-oncogene in bronchoalveolar mononuclear cells was enhanced. Enhancement of c-sis tra...
Vanillin offers interesting possibilities for corrosion inhibition because of its safe use and highsolubility in water. The effect of vanillin on the corrosion inhibition of AISI 304 stainless steel in0.5M H2SO4 solution has been studied using potentiodynamic polarization and electrochemicalimpedance spectroscopy (EIS). Furthermore, this paper demonstrates that the electrochemical noise(EN) tec...
