Background: Little is known regarding the interaction of dental implant surface nanotubes and oral soft and hard tissues. The purpose of this study was to evaluate both histologically and radiographically the qualitative and quantitative effects of dental implant surface nanotubes on hard and soft tissue in a canine model.
Methods: Three subgroups consisting of a combination of test and control implants and abutments (Group A: control implant/control abutment, Group B: control implant/test abutment: Group C: test implant/test abutment) were placed in edentulous mandibles of six large-breed canines. Implants and abutments were placed on one side at baseline, and on the opposite side of the mandible at week 10; sacrifice occurred at week 12. Quantitative and qualitative analyses were used to measure newly formed hard and soft tissues histologically and radiographically.
Results: The mean radiographic change in marginal bone level from weeks 0 to 12 between implant groups was not statistically significant (P > 0.05). Mean soft tissue contact (junctional epithelium + connective tissue) for Groups A, B, and C were 2.29, 2.33, and 2.31 mm, respectively, with no statistically significant difference (P > 0.05) between the groups. All connective tissue fibers were oriented parallel to the abutment regardless of surface treatment.
Conclusions: The findings of this study suggest that healing of hard and soft tissues around implants and abutments is similar when comparing grit-blasted surfaces to machined, turned surfaces with nanotubes. Both resulted in similar soft tissue contact values, as well as connective tissue fiber orientation.

Background: Synovial sarcoma (SS) is classified as an aggressive high-grade soft tissue sarcoma that predominantly affects the extremities. Despite its prevalence in the extremities (up to 80%), diagnostic and treatment challenges persist. This study aims to address these challenges by providing a comprehensive analysis of SS in extremities, focusing on diagnostic accuracy and treatment outcomes.

Introduction Surgical resection remains a standard treatment of non-functioning pituitary adenomas (NFPA). These tumors have significant intratumoral variability of growth rates and texture hardness. This preliminary study aims to identify variations in gene expression of different locations and textures within the same tumor to better explain tumor pathophysiology.

The prevalence of oromaxillofacial fracture in pediatric patients is comparatively less than in adults, which could be due to several inconclusive factors, such as infrequent exposure to high-contact sports games, rash driving of vehicles and motorbikes, alcohol consumption, and fist fights for personal reasons under the influence of alcohol. More importantly, most of the time, children are under the care of their parents till they reach an age of maturity. One more thing that everyone believes even today is the elasticity nature of their bones as well as their body weight during their growing stage.

While the number of studies investigating Achilles tendon pathologies has grown exponentially, more research is needed to gain a better understanding of the complex relation between its hierarchical structure, mechanical response, and failure. At the microscale, collagen fibers are, with some degree of dispersion, primarily aligned along the principal loading direction. However, during tension, rearrangements and reorientations of these fibers are believed to occur.
