Image analysis of immediate full-arch prosthetic rehabilitations guided by a digital workflow: assessment of the discrepancy between planning and execution.

Background: A dentition with adequate function and esthetics is essential for the well-being and quality of life. A full implant-retained fixed prosthetics is an ideal solution for fully edentulous arch, however requires complex planning, surgical, and prosthetic procedure. With the help of digital workflow, it becomes a predictable and fast solution for the dentists and the patients.

Randomized controlled clinical trial comparing two dental implants with different neck configurations.

Background: Peri-implant bone levels can vary according to the implant neck macro-design and the implant-abutment interface.

Purpose: To compare the changes in soft and hard tissues when using a one-piece implant with a machined collar (TG) versus a two-piece implant with a progressive platform widening and a platform switching connection (SP).

Material And Methods: Partially edentulous patients willing to receive one or two implants in the posterior maxilla or mandible were randomized to the control (TG) or to the test group (SP).

Estimation of the site of wheezes in pulmonary emphysema: airflow simulation study by the use of A 4D lung model.

Adventitious lung sounds in pulmonary emphysema, wheezes, are continuous musical sounds during expiration with 400 Hz or more. The textbook tells that expiratory airflow limitation in emphysema occurs at the peripheral airways and that wheezes are generated there. We have recently proposed a novel hypothesis based on image analysis and theoretical consideration that expiratory airflow limitation in emphysema occurs at the intra-mediastinal airway (trachea, main bronchi, and right lobar bronchi) due to compression by overinflated lungs.

Multifocal epithelial hyperplasia: A potentially precancerous disease? (Review).

Multifocal epithelial hyperplasia (MEH), also known as Heck's disease, manifests as a papulonodular lesion in the oral mucosa and has been associated with the human papillomavirus, a virus related to various precancerous diseases in the oral cavity. It has a predisposition for the female gender and for children. Although the majority of reported cases have been among American Indians and Eskimos, it has been described in multiple ethnic groups in various geographical locations.

Identification of RNA-binding proteins in RAW 264.7 cells that recognize a lipopolysaccharide-responsive element in the 3-untranslated region of the murine cyclooxygenase-2 mRNA.

RAW 264.7 cells rapidly induce cyclooxygenase-2 (COX-2) in response to lipopolysaccharide treatment. Part of the increased COX-2 expression occurred through post-transcriptional mechanisms mediated through specific regions of the 3'-untranslated region (UTR) of the message.
