Hundreds of thousands of people worldwide are diagnosed with kidney cancer each year, and this disease is more common in developed societies. Approximately 30% of patients with kidney cancer are recognized at the metastatic stage. Segmentation is an important process in the computer-aided treatment planning of kidney diseases. For this reason, more importance should be given to studies focused on segmentation as accurate segmentation is of high importance in the medical sense. This paper focuses on an improved version of the existing U-Net3D models. The aim is to assist physicians struggling with kidney segmentation. The improved U-Net3D model showed better performance than U-Net, U-Net+ResNet, and U-Net++ models, with 97.89% accurate segmentation.

The field of orthodontics in its new era is venturing ahead to more up-to-date technological point of view. Digital technology has a significant effect on our lives ever since the modernization of mobile phones. The advances in technology have remodelled the diagnosis and treatment plan in the field of medicine. Digital workflows are currently increasing in the orthodontic practice and has touched every aspect of orthodontics – with transformations in the documentation, study casts, analysis of a dental malocclusion, smile designing, treatment planning and for fabrication of orthodontic appliances. Three - dimensional imaging of the dentition, skeletal components and the face allows for treatment planning in three dimension and use of computer aided design (CAD) and computer aided manufacturing (CAM) for customization of orthodontic appliances. Software integration of digital models, 3D facial imaging and cone-beam computed tomography (CBCT) makes it possible to simulate the treatment plan and to attain a good communication with the patients. Recent advancement in digital videography has allowed the clinicians to capture patient’s speech, oral and pharyngeal function, and smile at the same time. Effective and optimal tooth movement required for the patient can also be monitored with the digitalization. Moreover, this digital platform has created the advantage of accessing the patient’s information from any location with the help of cloud based computing storage systems. These advancements have improved the efficiency, accuracy, consistency, and predictability of the treatment outcomes and have also led to progress in educational component and communication. The digitalization is bringing about a revolutionary change in the field of diagnosis and treatment planning, posing a challenge to clinical efficiency and knowledge. KEY WORDS Digital Orthodontics, Digital Workflow, Digital Dental Models, Digital Radiography, CAD CAM, Orthodontics, Review

SUMMARY Interdisciplinary treatment planning is necessary in certain clinical situations to optimize esthetic treatment outcomes. Patients presenting with severe wear of their anterior teeth from iatrogenic influences pose a particularly difficult problem in terms of esthetic treatment planning. Collaboration of practitioners from the disciplines of orthodontics, periodontics, and restorative dentistry is essential for the treatment of patients with complex esthetic dental needs. Careful assessment of clinical situations and corresponding specialty consultations are of utmost importance to achieve more predictable and esthetic treatment outcomes. The purpose of this clinical case is to report to the readership a novel digital fabrication of computer-aided design/computer-aided manufacturing milled acrylic provisional restorations and final lithium disilicate definitive restorations after orthodontic and periodontal therapy with virtual master impressions, casts, and articulation.

COX-2/mPGES-1/PGE2 cascade plays critical roles in modulating many physiological and pathological actions in different organs. In the kidney, this cascade is of high importance in regulating fluid metabolism, blood pressure, and renal hemodynamics. Under some disease conditions, this cascade displays various actions in response to the different pathological insults. In the present review, the roles of this cascade in the pathogenesis of kidney injuries including diabetic and nondiabetic kidney diseases and acute kidney injuries were introduced and discussed. The new insights from this review not only increase the understanding of the pathological role of the COX-2/mPGES-1/PGE2 pathway in kidney injuries, but also shed new light on the innovation of the strategies for the treatment of kidney diseases.
