Dentin sialophosphoprotein (DSPP) gene mutations cause autosomal dominantly inherited diseases. DSPP gene mutations lead to abnormal expression of DSPP, resulting in a series of histological, morphological, and clinical abnormalities. A large number of previous studies demonstrated that DSPP is a dentinal-specific protein, and DSPP gene mutations lead to dentin dysplasia and dentinogenesis imperfecta. Recent studies have found that DSPP is also expressed in bone, periodontal tissues, and salivary glands. DSPP is involved in the formation of the periodontium as well as tooth structures. DSPP deficient mice present furcation involvement, cementum, and alveolar bone defect. We speculate that similar periodontal damage may occur in patients with DSPP mutations. This article reviews the effects of DSPP gene mutations on periodontal status. However, almost all of the research is about animal study, there is no evidence that DSPP mutations cause periodontium defects in patients yet. We need to conduct systematic clinical studies on DSPP mutation families in the future to elucidate the effect of DSPP gene on human periodontium.
Conclusion: Tumor voxel dose response SF2 can be derived using multiple FDG-PET imaging obtained during the early weeks of radiation treatment. Distribution of SF2 has significant predictability power on tumor local failure, and the recurrent location. It can be used as the objective function to target radio-resistant tumor cells.
With the development of the new era and the continuous progress of society, people are facing more and more pressures in their daily lives. Most people experience negative emotions such as doubt, anxiety and restlessness, and lose confidence in life. This is a red flag that should be heeded. Positive psychology plays an indispensable role in the new era. It can help people get out of the psychological haze. In the new era, positive psychology has become the first choice for most people to deal with mental illness. From the perspective of positive psychology in the new era, this paper uses the SPSS analysis method to analyze the number of samples, and analyzes the connotation and characteristics of positive psychology.
Semiconductor industry as a measure of a country's light industry level, has its own development history. This article will give a systematic account of the history of the technology used to produce integrated circuits on chips used in silicon electronics, as well as concepts and solutions to power consumption problems, for those who want to enter this industry. In the former case, we will quote data and compare and analyze them to highlight the characteristics of the development over a certain period. For the latter, we will argue and explain more from the principle point of view.
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.
