Abstract:
Lymphomas are frequent malignant neoplasms, due to the destructive and rapidity of their clinical course, they present extensive areas of necrosis, which could be induced by the Epstein Bar virus (EBV) that is present in most of these lymphomas causing oro-nasal communications that they have an impact on phonation, chewing, swallowing and loss of self-esteem. Due to the extension of this type of communication, they represent a challenge in surgical rehabilitation opting for a prosthetic device.

    
Introduction
Lymphomas are a group of neoplasms originating in the immune system, whose cells are widely distributed and have an extensive functional range. In the head and neck region there is a high incidence of nasal type T / NK cell lymphomas associated with the Epstein Var virus (EBV) showing a similar pattern of strain type distribution between neoplastic tissues and reactive processes. EBV may infect cells of the T / NK lineage, raising the possibility of exposure of the nasal, nasopharyngeal, hard and soft palate mucosa. It is also argued that EBV may participate in the induction of cytokines, in particular tumor necrosis, factor kappa-β and metalloproteases in virally infected cells, causing areas of necrosis.1 The oral cavity, the nasal cavity, the maxillary sinuses and the rest of the oropharynx area is constituted by the presence of the hard palate that structurally forms a physical barrier and the soft palate that together with a series of movements of the pharyngeal walls achieves the separation and coupling of the nasal space with the oral and pharyngeal space. The anatomical integrity of both is important to ensure proper function. Maxillary defects can be restored by means of a prosthetic device designed to close these acquired communications. A palatal obturator is defined as a prosthetic device designed

 Lateral Rock Characteristic Evidence of Hydrocarbon Restoration from Post-Stack Impedance Inversion: A Case Study of ZED-field Offshore Niger Delta Lateral predictions of rock properties that are descriptive of a reservoir have been studied using a model-established seismic inversion approach that was used to convert input seismic data into an acoustic impedance structure to optimize hydrocarbon restoration in the field. This was actualized by integrating wireline logs and 3D post stack seismic data procured from ZED-Field offshore Niger Delta. The inversion system employed in this study comprises of forward modelling of reflection coefficients starting with a low-frequency impedance model induced from well logs and convolution of the reflection coefficients with the source wavelet extracted from the seismic input. P-impedance analysis at reservoir C5000 delineated from the control well gave a near perfect correlation of 0.998109 (≈ 99.8 %) between the original P-impedance log, in...

 Sustainable Development: Reality Or Myth? Since the United Nations Environment Conference in Stockholm (1972), the concept of sustainable development has steadily made its way among individual scientists and international organizations. The apotheosis of this development was the adoption by the United Nations in 2015 of the 17 Sustainable Development Goals. However, many scientists and politicians were skeptical about the concept of sustainable development, since the results of implementing sustainable development in different countries were far from expected. Many decisions taken at the level of the UN and other international organizations turned out to be unfulfilled. In my opinion, as well as some other Russian scientists, the concept of sustainable development is an unrealistic project, it is a myth, although it is very positive and humane. Sustainable development goals can be achieved only by the most economically developed countries entering the era of post-industrialism. In...

 How to Treat Cancer Properly Cancer is one of the deadliest diseases in the world, chemotherapy is effective under some conditions, but has too heavy side effects, and it is not effective to a considerable proportion of cases while the side effects are often life-threatening, drugs (not unhealthy addictive drugs mentioned in reference four, the drug in reference four only mean those makes people addictive but does no good to health, destroying health quickly) are not always available to improve the condition. However, sport is a potential treatment that is effective to cancer before the cancer is disseminated, this gets little attention but is true both in theory and practice. The physical activities that have moderate intensity and duration should have devastating effects on cancer cells, they make the body hot and reduce the nutritional resources that cancer cells can get, also renew the proteins in the body and improve one’s mood, cancer cells are hard to live when one is activ...
