If periodontitis, or gum disease, is left untreated, it can lead to strokes, diabetes, heart disease and the onset of dementia. The alveolar bone is an area of the mouth that is particularly impacted by periodontal disease and periodontists have therefore been searching for a means of regenerating lost alveolar bone with periodontal tissue. Dr Shogo Takashiba, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences at Okayama University, is working to help patients retain the oral functions they require for nutrition and to develop means of managing infection and inflammation, thereby improving general health. In particular, he and his team are looking at preventing biofilm-related infection, evaluating infection and inflammation, and regenerating periodontal tissue. A key focus for the researchers is on producing cost-effective methods for treating periodontal disease and, as such, they are working to develop anti-biofilm reagents for long-term use considering emerging issue of antimicrobial resistance. Part of this work involves cetylpyridinium chloride hydrate (CPC) and Takashiba and the team have developed a strategy to prevent the development of biofilm by combining phosphorylated pullulan and CPC. They have obtained patents for their oral wash, rinse and ointments in Japan, China, the US, the EU and Canada and are now looking at how to produce these regenerative and anti-biofilm treatments on an industrial scale, which will enable the general public to access the innovative treatments.

Two workshops were part of the final steps in the Economic and Social Research Council (ESRC) commissioned Ways of Being in a Digital Age project that is the basis for this Handbook. The ESRC project team coordinated one with the UK Defence Science and Technology Laboratory (ESRC-DSTL) Workshop, “The automation of future roles”; and one with the US National Science Foundation (ESRC-NSF) Workshop, “Changing work, changing lives in the new technological world.” Both workshops sought to explore the key future social science research questions arising for ever greater levels of automation, use of artificial intelligence, and the augmentation of human activity. Participants represented a wide range of disciplinary, professional, government, and nonprofit expertise. This chapter summarizes the separate and then integrated results. First, it summarizes the central social and economic context, the method and project context, and some basic definitional issues. It then identifies 11 priority areas needing further research work that emerged from the intense interactions, discussions, debates, clustering analyses, and integration activities during and after the two workshops. Throughout, it summarizes how subcategories of issues within each cluster relate to central issues (e.g., from users to global to methods) and levels of impacts (from wider social to community and organizational to individual experiences and understandings). Subsections briefly describe each of these 11 areas and their cross-cutting issues and levels. Finally, it provides a detailed Appendix of all the areas, subareas, and their specific questions.

Abstract The Internet Archive curated a 90-terabyte sub-collection of captures from the US government's public website domain (‘.gov’). Such archives provide largely untapped resources for measuring attributes, behaviors and outcomes relevant to political science research. This study leverages this archive to measure a novel dimension of federal legislators' religiosity: their proportional use of religious rhetoric on official congressional websites (2006–2012). This scalable, time-variant measure improves upon more costly, time-invariant conventional approaches to measuring legislator attributes. The authors demonstrate the validity of this method for measuring legislators' public-facing religiosity and discuss the contributions and limitations of using archived Internet data for scientific analysis. This research makes three applied methodological contributions: (1) it develops a new measure for legislator religiosity, (2) it models an improved, more comprehensive approach to analyzing congressional communications and (3) it demonstrates the unprecedented potential that archived Internet data offer to researchers seeking to develop meaningful, cost-effective approaches to analyzing political phenomena.

Background: Oral pathogens may exert the ability to trigger differently the activation of local macrophage immune responses, for instance Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans induce predominantly pro-inflammatory (M1-like phenotypes) responses, while oral commensal microbiota primarily elicits macrophage functions consistent with the anti-inflammatory (M2-like phenotypes). Methods: In healthy individuals vs. periodontal disease patients’ blood samples, the differentiation process from monocyte to M1 and M2 was conducted using two typical growth factors, the granulocyte/macrophage colony stimulating factor (GM-CSF) and the macrophage colony stimulating factor (M-CSF). Results: In contrast with the current literature our outcomes showed a noticeable increase of macrophage polarization from healthy individuals vs. periodontal patients. The biological and clinical significance of these data was discussed. Conclusions: Our translational findings showed a significant variance between control versus periodontal disease groups in M1 and M2 marker expression within the second group significantly lower skews differentiation of M2-like macrophages towards an M1-like phenotype. Macrophage polarization in periodontal tissue may be responsible for the development and progression of inflammation-induced periodontal tissue damage, including alveolar bone loss, and modulating macrophage function may be a potential strategy for periodontal disease management.

Resume. The high prevalence of periodontal disease causes the urgency of finding ways to improve methods of diagnosis, treatment and prevention of complications of this disease. The complex clinical picture requires a differentiated approach to the choice of orthopedic rehabilitation of such patients taking into account the patient's age, degree of pathological changes and activity of the pathological process with mandatory immobilization of movable teeth by different types of splints and splint dentures. Depending on the degree of pathological changes in periodontal tissues, the size and topography of dentition defects and the severity of destructive-resorptive processes in the alveolar bone, the replacement of dentition defects should be planned using dental implants and splinttype dentures. The aim of the study. Improving the effectiveness of orthopedic treatment of periodontal diseases, burdened by defects of the dentition through the differentiated use of dental implants and splinting structures. Materials and methods. A comprehensive clinical and laboratory examination of 237 patients with clinically diagnosed periodontitis I–III degree, burdened by partial loss of teeth. From the specified contingent of persons we carried out orthopedic treatment of 98 patients aged from 30 to 69 years with periodontal diseases of various severity, aggravated by defects of dentitions of various size and localization. Cone-beam computed tomography was used for objective quantitative and qualitative assessment of periodontal tissue and bone tissue of the edentulous jaw in individuals with various clinical forms of periodontal disease, to determine the relative densitometric density of bone tissue, when planning dental implantation and for control its results. The localization of supracontacts was determined by occlusion. Diagnosis and elimination of traumatic occlusion were performed according to Jenkelson and Schuller [3]. Evaluation of the stability of dental implants was performed by frequency – resonance analysis of the stability of dental implants using the Osstell ISQ device. Results. According to the results of examination of 237 people and the division of patients into three age groups, the clinical features of the pathological process in the age aspect were established. The results of computed tomography of the dental apparatus of the subjects showed that periodontal disease in the age aspect in the dynamics is accompanied by the severity of destructive-resorptive processes in the alveolar bone, which are manifested in a decrease in the relative densitometric density of bone marrow and bone loss. Orthopedic rehabilitation of this contingent of persons was performed with the use of biologically indifferent structural materials and splinting orthopedic structures, including splinting of abutment teeth, removable prosthetics and dental implantation, as well as accompanying physiotherapy of prostheses. In the case of periodontitis of I–II degree with sufficient volume and density of bone tissue in the area of the dentition defect, high clinical efficacy was shown by the use of dental implantation in the case of gradual loading of the dental implant using a superstructure of own development. In the presence of medium and large defects of the dentition on the background of periodontitis II–III severity in the presence of significant pathological mobility of abutment teeth and insufficient volume and density of bone tissue in the area of the defect sufficient clinical effectiveness showed the use of removable dentures own design. Conclusions. Periodontal diseases in the age aspect in the dynamics are accompanied by pronounced destructive-resorptive processes in the alveolar bone, which are manifested by a decrease in the relative densitometric density of bone tissue and progressive loss of height of the alveolar process. Timely application of dental implantation due to the dosed gradual occlusal load on the alveolar bone helps to preserve the structure of the alveolar bone and the height of the alveolar process. In the presence of medium and large defects of the dentition on the background of periodontitis II–III severity in the presence of significant pathological mobility of abutment teeth and insufficient volume and density of bone tissue in the area of the dentition defect, the use of removable dentures of splinttype design is shown. To prevent complications of prosthetics and prolong the use of orthopedic structures, it is advisable to use photodynamic maintenance therapy. Key words: periodontal tissue disease, dentition defect, dental implantation, splint-type denture.

Comprehensive and appropriate occlusion reconstruction therapy is necessary for orthodontic treatment of adult patients with malocclusion with periodontal disease associated with occlusal trauma. We report the case of a patient with extensive moderate chronic periodontitis associated with occlusal trauma. The patient was diagnosed with extensive moderate chronic periodontitis associated with occlusal trauma and underwent thorough treatment for periodontal disease, oral management, and 20 months of orthodontic therapy. Moreover, reconstructed occlusion was performed to evaluate occlusal trauma for visualization using Brux Checker (BC) analysis before and after active orthodontic treatment. The patient acquired stable anterior guidance and a functional occlusal relationship. BC findings revealed weakening of the functional contact between the lateral occlusal force of the dentition and the front teeth and alveolar bone regeneration. The laminar dura became clearer, and the periodontal tissue improved. Our results suggest that assessment of occlusion function using BC analysis and periodontal examination was effective in enabling occlusal treatment goal clarification through orthodontic treatment in case of periodontal disease associated with occlusal trauma.

Neuromyelitis optica (NMO) is a recurrent inflammatory disease that preferentially targets the optic nerves and spinal cord leading to blindness and paralysis. The hallmarks of NMO include bilateral optic neuritis and longitudinally extensive transverse myelitis. Woman and African Americans are overrepresented in the US patient population. NMO is associated with the NMO-IgG biomarker, which targets the aquaporin-4 water channel on astrocytes. The humoral pathology of NMO lesions include IgG and IgM deposits and infiltration by granulocytes suggesting that the NMO-IgG may be involved in the pathogenesis of disease. This review of the recent NMO literature covers the clinical features, epidemiology, radiology and pathology of disease and includes discussion of the important basic science research work in the field.


In the era of Globalization, advancement of technology and stiff competition, particularly, in the I.T. Industry, companies have to adopt new H.R. strategies and practices so as to constantly evolve and grow. In this context, existing recruitment strategies have to be replaced by new strategies. Many companies are now extensively depending on the internet to connect to larger audiences globally. Organizations are in a position to attract profiles, resumes from potential candidates by announcing their vacancies on their own websites. E-recruitment is evoking interest among the companies typically over the last few years. The spread of information technology and growth of Internet has paved way for companies willing to hunt for talent on the job seeking websites. In the years to come, social networking will soon be an indispensable part of the hiring process. It is cost effective, does not require setting up an office and forms an effective tool for recruiters. The main purpose of this study was to understand the application of factor analysis in social science research and to reduce a large number of variables into manageable smaller factors for further analysis of the employers’ perception on social media recruitment with reference to the I.T. Sector in Bangalore.

Abstract Various simulation type tools and conventional algorithms are being used to determine knee muscle forces of human during dynamic movement. These all may be good for clinical uses, but have some drawbacks, such as higher computational times, muscle redundancy and less cost-effective solution. Recently, there has been an interest to develop supervised learning-based prediction model for the computationally demanding process. The present research work is used to develop a cost-effective and efficient machine learning (ML) based models to predict knee muscle force for clinical interventions for the given input parameter like height, mass and angle. A dataset of 500 human musculoskeletal, have been trained and tested using four different ML models to predict knee muscle force. This dataset has obtained from anybody modeling software using AnyPyTools, where human musculoskeletal has been utilized to perform squatting movement during inverse dynamic analysis. The result based on the datasets predicts that the random forest ML model outperforms than the other selected models: neural network, generalized linear model, decision tree in terms of mean square error (MSE), coefficient of determination (R2), and Correlation (r). The MSE of predicted vs actual muscle forces obtained from the random forest model for Biceps Femoris, Rectus Femoris, Vastus Medialis, Vastus Lateralis are 19.92, 9.06, 5.97, 5.46, Correlation are 0.94, 0.92, 0.92, 0.94 and R2 are 0.88, 0.84, 0.84 and 0.89 for the test dataset, respectively.
